<About the rotating machine transport vehicle 10>
FIG. 1 is a perspective view of a rotating machine transport vehicle 10 according to a first embodiment of the present invention as viewed from the left front side. FIG. 2 is a perspective view of the rotating machine transport vehicle 10 according to the first embodiment when viewed obliquely from the left rear. In the drawings below FIG. 1 described below, X, Y, and Z directions are shown as appropriate. Here, the X direction is the front-rear direction of the rotating machine transport vehicle 10, the Y direction is the width direction of the rotating machine transport vehicle 10 (the direction perpendicular to the X direction in the horizontal direction), and the Z direction is the vertical direction of the rotating machine transport vehicle 10. It is.
The rotating machine transport vehicle 10 includes a rotating machine system 1 and a tractor 20 that is detachably connected to the rotating machine system 1 and pulls and transports the rotating machine system 1.

  The rotary machine system 1 includes a trailer 30 and a rotary machine installation base 100 (hereinafter referred to as “base 100”) mounted on the trailer 30 and fixed to the loading platform 31. Further, the rotary machine system 1 includes a motor 101 (also an inverter or the like) that is a driving machine, a speed increasing machine 102 that is a driven machine driven by a driving machine such as the motor 101, and the like. A compressor 103 and other auxiliary machines 131 are provided. The motor 101 (or a reciprocating engine, a gas turbine, etc.), the speed increaser 102, the compressor 103, etc. are all rotating machines provided with a rotating body. The driving machine may use an internal combustion engine or the like instead of the motor 101. Hereinafter, the motor 101, the speed increaser 102, and the compressor 103 are collectively referred to as a rotating machine 40.

The base 100 on which such a rotary machine 40 or the like is installed may be lifted by a forklift or a crane and placed on the trailer 30. Alternatively, a plurality of cylindrical rollers may be used to move the base 100 on which the rotary machine 40 or the like is installed and pull it up on the trailer 30. The base 100 placed on the trailer 30 in this way is fixed on the loading platform 31 of the trailer 30 (details will be described later).
In FIGS. 1 and 2, only the frame 50 surrounding the base 100 and the rotating machine 40 on the trailer 30 is illustrated. However, when the base 100 and the rotary machine 40 are transported, a panel that covers the base 100 and the rotary machine 40 is actually provided on the frame 50.

  The applications of the rotating machine 40 as described above are as follows. That is, a pipeline is used as one means for transporting a fluid such as natural gas over a long distance. In the pipeline, compressors are provided at various places to pump (pump) the fluid. That is, pressure is applied to the fluid in the pipe of the pipeline by the compressor, and the fluid flows in the pipe by this pressure.

  In a region where a plurality of pipelines are installed in parallel, when one pipeline is closed due to trouble or the like, fluid such as natural gas remaining in the pipeline is removed. I have to. Therefore, the closed pipeline and another pipeline installed in parallel with the pipeline are connected by, for example, a temporary line, and the fluid is pumped from the former to the latter. In this case, it is necessary to bring a compressor or the like to the site to pump the fluid. Devices such as the rotating machine 40 are used at such times. In addition, when a predetermined section of one pipeline is closed and the natural gas or the like in the closed section is returned to the upstream section that is not closed, an apparatus such as the rotating machine 40 is used. That is, in the rotary machine 40, the motor 101 is used as a drive source, the rotational speed of the output shaft of the motor 101 is increased by the speed increaser 102, and the compressor 103 is rotationally driven at the increased rotational speed to fluid such as natural gas. Pump. In FIGS. 1 and 2, illustrations of connecting portions such as an output shaft and an input shaft of each device are omitted (may be omitted as appropriate in the drawings of FIG. 3 and subsequent drawings). The rotating machine 40 is carried to a place where the temporary line is installed, and is used in the place for a necessary period. After the intended work is completed, another place (new work place, Or carry it to the warehouse. That is, these rotary machines 40 are mobile devices.

  Therefore, the rotating machine 40 is placed on the trailer 30 and carried to the destination. In this case, it is desired that the trailer 30 can use a general-purpose trailer generally used in logistics. That is, in order to use a general-purpose trailer generally used in physical distribution as the trailer 30, it is necessary to sufficiently suppress vibration of the rotating machine 40 during transportation. Moreover, it is necessary to be able to suppress the vibration caused by the operation of the rotating machine 40 and the like so that the rotating machine 40 and the like can be operated even in a soft ground. Furthermore, when the engine of the tractor 20 is operating, it is necessary to protect the compressor 103 and the like from the vibration of the engine. In other words, for these purposes, it is essential to provide a mechanism for vibration isolation in the base 100 so that a special trailer having a mechanism for vibration isolation need not be used.

Here, the compressor 103 and the like are protected from the vibration of the engine of the tractor 20 by driving the engine in the tractor 20 to a part of the electric power used to operate the rotating machine 40 and the like on the base 100. This is because the generated power may be used. That is, since the engine of the tractor 20 is also operated during the operation of the rotating machine 40, the vibration of the engine of the tractor 20 is transmitted to the rotating machine 40, and thus it is necessary to protect the compressor 103 and the like from the vibration. In other words, there are cases where only the tractor 20 (or both the tractor 20 and the trailer 30 is returned after the rotary machine 40 is lowered) after the rotary machine 40 is transported on the trailer 30 to the destination. It must be taken into account that 20 may be used locally in a connected state.
Thus, in order to use a general-purpose trailer as the trailer 30, it is necessary to provide a mechanism for vibration isolation in the base 100. In this case, it is necessary to reduce the weight of the base 100 for the convenience of transportation while preventing vibration by the base 100 and firmly supporting the heavy rotating machine 40 and the like.

<About Base 100>
Below, the structure and operation | movement of the base 100 used as a means for solving these subjects are demonstrated in detail.
FIG. 3 is a perspective view of the rotating machine installation base 100 according to the first embodiment of the present invention as viewed obliquely from below. FIG. 4 is a top view of the rotary machine installation base 100 according to the first embodiment, and FIG. 5 is a bottom view of the rotary machine installation base 100 according to the first embodiment.
In other words, the base 100 takes into account the arrangement and weight of each device to be installed, and appropriately arranges the girders, which are strength members in the base 100, to reduce the amount of girders, thereby reducing the manufacturing cost and weight. Plays.

  First, on the base 100, for example, from the rear side of the rotating machine transport vehicle 10 in the X direction, a drive installation area 104 where a drive machine such as a motor 101 is installed, a speed increaser 102 driven by the drive machine, A driven machine installation area 105 in which a driven machine such as the compressor 103 is installed, and an auxiliary machine installation area 106 in which other auxiliary machines 131 are installed are sequentially provided. 3 and the subsequent drawings, the auxiliary machine 131 (FIGS. 1 and 2) is not shown.

On the upper surface portion of the base 100, a plate material 100i such as a rust-proof steel plate is fixed to a later-described girders (110 to 115) by welding. The plate member 100i may be fixed to the girders by a method other than welding, such as bolts and rivets, but welding is desirable in that continuous fixing is possible.
Two anti-vibration devices 107 and 108 are installed in the lower part of the drive installation area 104 where the vibration due to the weight of the drive machine such as the motor 101 and the rotational motion is applied.
One anti-vibration device 109 is installed below the driven machine installation area 105 to which vibration due to the weight and rotational motion of the speed-up gear 102 and the compressor 103 of the driven machine is applied. That is, the base 100 is supported by a total of three vibration isolation devices 107, 108, and 109.

The anti-vibration devices 107, 108, and 109 are configured by springs, dampers, and the like. Specifically, the vibration isolators 107, 108, and 109 attenuate the applied vibration by elastic energy due to the rigidity of the spring, internal friction of the spring, viscous damping force of the damper, and the like. The anti-vibration devices 107, 108, and 109 may be members having elasticity and damping action such as rubber other than springs and dampers.
That is, in general, the motor 101 is heavy among the devices installed on the base 100, and vibration due to motor torque is large. Therefore, two of the three anti-vibration devices 107 and 108 are installed below the drive unit installation area 104, and the base is adapted to the load and vibration (forced vibration, natural vibration, etc.) of the motor 101. The deformation of 100 is suppressed.
The base 100 is constructed of a plurality of girders (110 to 115) and a plate 100i to support each device on the base 100. The girders (110 to 115) are H-shaped steel or the like, and the plate is a steel plate or the like subjected to rust prevention treatment.

<About the driving machine installation area 104 and the driven machine installation area 105>
In the driving machine installation area 104 and the driven machine installation area 105, main girders 110 extending in parallel to or along the longitudinal direction of the base 100 on both side surfaces (including the vicinity of both side surfaces) of the base 100 as girders, 110 is installed as a pair.
The main girder 110 covers the entire range of both areas 104 and 105 or a part of the range across both areas 104 and 105 so that both the drive machine installation area 104 and the driven machine installation area 105 are mounted. Installed. 3 to 5 show a case where the main girders 110 and 110 are provided on both side surfaces of the drive machine installation area 104 and the driven machine installation area 105.
The vibration isolators 107 and 108 are attached to the main beam 110 on both side surfaces.

In the drive machine installation area 104 and the driven machine installation area 105, heavy equipment such as the motor 101 of the drive machine and the compressor 103 of the driven machine is installed. Therefore, in order to suppress deformation in the gravity direction of the base 100 (deformation in the downward direction of the Z axis in FIG. 3) by these devices, the main girder 110 is more rigid than each other girder (described later). Is high.
In consideration of the shaking of the base 100 during transportation, the inertial force of the shaking of the base 100 and the rotary machine 40 is not limited to the direction of gravity of the base 100 (the lower direction of the Z axis), but also the width of the base 100. Since it also affects the direction (the short direction of the base 100, the Y-axis direction), it is necessary to improve the rigidity of the base 100 in the width direction.

In consideration of this, in the first embodiment, high-rigidity main girders 110 are installed on both side surfaces of the base 100, and this structure allows the entire width of the base 100 (the short direction of the base 100, the Y-axis direction). ) Is improved, and deformation of the base 100 in the width direction can be suppressed.
In addition to the main girder 110, a main machine stiffening girder extending in an arbitrary direction is installed in the driving machine installation area 104 and the driven machine installation area 105.

The main machine stiffening girder is appropriately installed as described below in consideration of the arrangement and weight of each device on the drive machine installation area 104 and the driven machine installation area 105.
For example, as shown in FIG. 3, below the motor 101 in the drive machine installation area 104, the main machine stiffening girder 111 that receives the weight of the motor 101 is placed in the width direction of the base 100 (the short direction of the base 100, the Y-axis direction). ) May be provided.
The vibration isolator 109 is attached to the central portion of the main machine stiffening girder 111a provided in the driven machine installation area 105 by extending in the width direction of the base 100 (short direction of the base 100, Y-axis direction). It is done.

  Further, from the installation position of the vibration isolator 109 below the compressor 103 in the driven machine installation area 105, extending toward the main girder 110 so as to be spaced apart from each other in a top view and fixed to the main girder 110. The two main machine stiffening girders 112 are installed. Specifically, one of the main machine stiffening girders 112 is fixed to a rigid portion by welding, bolting, or the like at the center of the main machine stiffening girder 111a to which the vibration isolator 109 is attached. Then, the other of the main machine stiffening girders 112 is fixed to the left and right main girders 110 by welding, bolting or the like.

  As a result, the two main machine stiffening girders 112 are viewed from above from the attachment location of the vibration isolator 109 (the longitudinal edge of the driven machine installation area 105 and the lower central portion in the width direction) toward the main girder 110. Thus, they are stretched while being spaced apart from each other in an oblique direction and fixed to the left and right main girders 110. Therefore, the rigidity with respect to the load of the drive machine installation area 104 and the driven machine installation area 105 in the XY plane direction (the horizontal plane direction of the base 100) and torsion around the axis in the XY plane direction can be increased.

In addition, the main machine stiffening girder can be extended and arranged in an arbitrary direction according to the weight and arrangement of the driving machine and the driven machine. Thereby, a suitable girder according to the weight and arrangement of the driving machine and the driven machine can be provided.
Since the main girder 110 bears most of the rigidity required for the drive machine installation area 104 and the driven machine installation area 105, the main machine stiffening girders 111, 111a, and 112 have lower rigidity than the main girder 110. May be.

  That is, the main machine stiffening girders 111, 111a, and 112 may have a reduced section modulus and a reduced rigidity by reducing the thickness or reducing the shape. In this way, the main machine stiffening girders 111, 111a, 112 can be reduced in size to save the amount of material, and compared with the case where all the girders in the base 100 have the same rigidity as the main girders 110. Thus, the manufacturing cost and weight associated with the raw material cost of the girder can be reduced.

<Auxiliary machine installation area 106>
As shown in FIGS. 3 to 5, any auxiliary machine installation area 106 other than the driving machine and the driven machine in which the auxiliary machine 131 (FIGS. 1 and 2) (not shown in FIGS. 3 to 6) is provided is arbitrary. Auxiliary stiffening girders 113, 114, 115 extending in the direction are installed. The auxiliary machine stiffening girders 113, 114, and 115 are appropriately installed as described below in consideration of the arrangement and weight of each device on the auxiliary machine installation area 106.
In general, since the auxiliary machine 131 is lighter than the main machine such as the motor 101 and the compressor 103, the load that the auxiliary machine installation area 106 receives from the auxiliary machine 131 is small.

Therefore, the auxiliary machine stiffening girder 113 provided on both side surfaces (including the vicinity of both side surfaces) of the auxiliary machine installation area 106 does not need a high-rigidity girder like the main girder 110 and may have low rigidity. 3 to 5 show a case where the auxiliary machine stiffening girders 113 are provided on both side surfaces of the auxiliary machine installation area 106.
That is, the auxiliary machine stiffening girder 113 may be connected to the main girder 110 so as to extend on the extension of the main girder 110 according to the installation area of the auxiliary machine 131, for example.

  As other accessory stiffening girders provided in the accessory installation area 106, for example, as shown in FIGS. 3 and 5, the auxiliary machine stiffening extending in the longitudinal direction of the approximate center of the accessory installation area 106 of the base 100. There is a digit 114. As other auxiliary stiffening girders, two auxiliary stiffening girders 115 extending from the auxiliary stiffening girders 114 toward the auxiliary stiffening girders 113 on both sides obliquely with each other when viewed from above are also provided. is there. Then, the auxiliary machine stiffening girder 114 and the auxiliary machine stiffening girder 115 are installed in a three-pronged shape in a top view corresponding to the auxiliary machine installation area 106. The trifurcated start point is located between the vibration isolator 109 installed in the lower part of the driven machine installation area 105 and the auxiliary machine 131 (FIGS. 1 and 2) on the auxiliary machine installation area 105. To do. Thereby, both the weight of the auxiliary machine 131 and the load supported by the vibration isolator 109 can be received at the trifurcated starting point.

  Further, the auxiliary stiffening girder 113 on both sides extending in the longitudinal direction and the auxiliary stiffening girder 114 on the central portion are moved from the central auxiliary stiffening girder 114 to the auxiliary stiffening girder 113 on both sides. The two auxiliary stiffening girders 115 extending obliquely from each other when viewed from above are connected. Thereby, the strength member can be formed in the X direction and the Y direction in the accessory installation area 106 only by the accessory stiffening girder 115 extending in the XY plane direction. That is, the auxiliary machine stiffening girder 115 is extended as a strength member in the X direction and the Y direction in the auxiliary machine installation area 106, and the rigidity of the auxiliary machine installation area 106 in the X direction and the Y direction can be added.

In addition, the accessory stiffening girder 115 extending in the XY plane direction can increase the rigidity against torsional deformation around the horizontal axis in the XY plane direction. And the auxiliary machine stiffening girder 114 in the central portion can effectively support the weight of the auxiliary machine 131 by passing below the auxiliary machine 131 (FIGS. 1 and 2) on the auxiliary machine installation area 106. it can.
In addition, the auxiliary machine stiffening girders 113, 114, and 115 can be extended and arranged in any direction according to the weight and arrangement of the auxiliary machine 131 (FIGS. 1 and 2). Thereby, an appropriate girder according to the weight and arrangement of the auxiliary machine 131 can be provided in the auxiliary machine installation area 106.

Also, considering that the girder is installed so as to be positioned below all the devices installed in the auxiliary machine installation area 106, for example, rather than simply installing the girder in a grid pattern in the X direction and the Y direction. If the girder is installed in an oblique direction like the auxiliary machine stiffening girder 115, the number of members can be reduced and the required rigidity can be secured, and the amount of girder can be reduced. Therefore, it is possible to reduce manufacturing costs and weights such as raw material costs and assembly costs of the base 100.
The auxiliary machine stiffening girder 113 may be connected to the main girder 110 and extended in any direction of the base 100 in the auxiliary machine installation area 106. Thereby, the auxiliary machine stiffening girder 113 can support the main girder 110 together with the loads of the driving machine installation area 104, the driven machine installation area 105, and the auxiliary machine installation area 106.

  Further, the auxiliary machine stiffening girders 113, 114, and 115 can be lower in rigidity than the main girder 110, as with the main machine stiffening girders 111, 111a, and 112, and the thickness and shape relating to the section modulus indicating the rigidity. It is possible to save material by reducing the dimensions. Therefore, compared with the case where all the girders in the base 100 have the same rigidity as the main girders 110, the amount of girders can be reduced, and the raw material cost of the girders and the manufacturing cost and weight associated with assembly can be reduced. .

  With the above-described configuration, an appropriate number of appropriate rigidity girders are provided in an appropriate position and direction in each of the drive machine installation area 104, the driven machine installation area 105, and the auxiliary machine installation area 106. Be placed. By optimizing each girder provided in the entire base 100 according to the driving machine, driven machine, and auxiliary machine, the manufacturing man-hours, the number of members, and the dimensions can be reduced, thereby reducing the manufacturing cost and the weight of the base 100. Is possible.

<Installation of base 100>
FIG. 6 is a perspective view showing an installation example of the rotating machine installation base 100 according to the first embodiment of the present invention.
For example, the vibration isolation devices 107, 108, and 109 of the base 100 are installed at the positions of the vibration isolation device installation portions 121, 122, and 123 of the loading platform 31 of the trailer 30, respectively. Specifically, the vibration isolators 107, 108, and 109 are fixed to the vibration isolator installation sections 121, 122, and 123 with bolts or welded by welding, for example.
As described above, the base 100 is firmly fixed on the loading platform 31 of the trailer 30, so that the rotary machine 40 is transported on the trailer 30 or when the base 100 and the rotary machine 40 are transported by the rotary machine transport vehicle 10. It is possible to prevent the base 100 from being displaced on the loading platform 31 during operation.

In addition, the girder (110, 111, 111a, 112, 113, 114, 115) installed in each area | region of the drive machine installation area | region 104 of this Example 1, the driven machine installation area | region 105, and the auxiliary machine installation area | region 106 is shown. Generally, H-section steel can be used, but various other shape steels such as I-section and T-section, and flat plates may be used.
Further, the main girder 110, the main machine stiffening girders 111, 111a, 112, and the auxiliary machine stiffening girders 113, 114, 115 may be different in rigidity.

  According to the rotating machine transport vehicle 10 of the present embodiment described above, the two anti-vibration devices 107 and 108 are provided at the lower part of the drive machine installation area 104 of the base 100, and the lower part of the driven machine installation area 105 is provided. One vibration isolator 109 is provided. These vibration isolators 107, 108, 109 can prevent vibration of the rotating machine 40 during transportation. In addition, vibration of the rotating machine 40 and the like can be prevented and the base 100 can be reduced in weight, so that the rotating machine transport vehicle 10 can be operated even on soft ground. Further, the vibration isolators 107, 108, and 109 prevent the vibration of the trailer 20 engine from being transmitted to the rotating machine 40 or the like even when the engine of the trailer 20 is operating while the rotating machine 40 or the like is operating. Therefore, it is possible to protect the motor 101 as the driving machine, the speed increaser 102 as the driven machine, the compressor 103, and the like from vibrations of the engine of the trailer 20. Therefore, the trailer 20 can be a general-purpose trailer that is used for general physical distribution, even if it is not a special vehicle having an anti-vibration function.

As described above, the base 100 includes the main beam 110, the main machine stiffening beams 111, 111a, 112, the auxiliary machine stiffening beams 113, 114, 115, and the like. The configuration and operation of each digit are as described above. Therefore, each digit can firmly support the motor 101 as a driving machine, the speed increaser 102 as a driven machine, the compressor 103, and the like.
In addition, since the main machine stiffening girders 111, 111a, 112 and the auxiliary machine stiffening girders 113, 114, 115 are lower in rigidity than the main girder 110 as described above, the weight can be reduced. In addition, the manufacturing cost can be reduced. Therefore, since no load is applied to the trailer 30, a general-purpose trailer 30 can be used as the trailer 30.

The rotating machine installation base 200 according to the second embodiment (hereinafter referred to as “base 200”) is obtained by adding a base hollow portion 217 between the drive machine installation area 204 and the driven machine installation area 205 to form a hollow base. The auxiliary machine 231 is installed in the section 217.
Of the base 200 according to the second embodiment, the parts having the same configuration and function as those of the base 100 shown in FIGS. The detailed description is omitted.

  FIG. 9 is a cross-sectional view of the base hollow portion 217 cut along line AA in FIG. By providing a base hollow portion 217 between the drive machine installation area 204 and the driven machine installation area 205, a connecting shaft between the drive machine such as the motor 201 and the driven machine such as the speed increaser 202 or the compressor 203 is provided. The auxiliary machine 231 is installed at a position where it does not interfere with 201j, that is, below the connecting shaft 201j. That is, the bottom position of the auxiliary machine 231 is lower than the position of the upper surface of the plate material 200i.

  By effectively utilizing the lower part of the connecting shaft 201j as the installation area of the auxiliary machine 231, the installation area of the auxiliary machine 231 (the installation space of the auxiliary machine 231) arranged in the auxiliary machine installation area 206, which was separately required, is reduced. As a whole, the base 200 becomes smaller and the weight of the base 200 can be reduced (in this case, the auxiliary machine installation area 206 shown in FIGS. 7 and 8 is unnecessary). Alternatively, the auxiliary machine installation area 206 can be effectively used for installation other than the auxiliary machine 231.

In addition, by installing the auxiliary machine 231 in the base hollow portion 217 at a low position in the base 200, the position of the center of gravity of the auxiliary machine 231 relative to the base 200 compared to the case where the auxiliary machine 231 is installed on the base 200. Can be lowered.
Thus, by lowering the position of the center of gravity of the auxiliary machine 231 within the base 200, the length of the arm of the moment of the auxiliary machine 231 with respect to the base 200 can be reduced. Therefore, the moment applied from the auxiliary machine 231 to the base 200 is reduced, and deformation of the base 200 can be suppressed.

Note that due to the influence of the base hollow portion 217, the plate material 200 i (corresponding to the plate material 100 i in the first embodiment) provided on the upper surface portion of the base 200 disappears in the base hollow portion 217. Therefore, although the rigidity of the base 200 itself is reduced, the auxiliary machine 231 is installed in the base hollow portion 217, and thus the rigidity of the auxiliary machine 231 is added to the base 200.
In addition, when the rigidity of the base hollow portion 217 is insufficient, a reinforcing girder 211k (FIG. 7) may be added to the outer peripheral portion surrounding the base hollow portion 217 or the bottom surface portion of the base hollow portion 217. The reinforcing girder may be H-shaped steel, other various shaped steels such as I-shaped and T-shaped, and flat plates.
The base hollow portion 217 may be provided so as to penetrate the base 200 in the height direction (Z-axis direction). If the auxiliary machine 231 does not interfere with the connection shaft 201j, the base hollow portion 217 may be disposed above the base 200. You may provide even a part of height direction.

FIG. 10 is a bottom view of the rotating machine installation base 300 according to the third embodiment of the present invention.
The rotating machine installation base 300 according to the third embodiment (hereinafter referred to as “base 300”) is configured such that the bases 100 and 200 according to the first and second embodiments are arranged at positions symmetrical to the base width center lines 100c and 200c. In contrast, the girder is arranged at asymmetric positions.

Of the base 300 shown in FIG. 10, parts having the same configuration and function as those of the base 100 shown in FIGS. 3 to 6 are illustrated by changing the reference numerals in the 100s to the 300s, and the description thereof is omitted.
The center of gravity of each device (driving machine, driven machine, auxiliary machine) installed on the base 300 is rarely in a symmetric position with respect to the base width center line 300c, and the weight of each device is also different. In general, the base 300 receives an asymmetric load with respect to the base width center line 300c.

  For example, as shown in FIG. 4, when the motor 101 and the compressor 103 are connected via the speed increaser 102, even if the motor 101 is arranged on the base width center line 100 c, The motor shaft center 101c and the compressor shaft center 103c are misaligned. Similarly, as shown in FIG. 8, when the motor 201 and the compressor 203 are connected via the speed increaser 202, the speed increaser 302 is used even if the motor 201 is disposed on the base width center line 200 c. The motor shaft center 201c and the compressor shaft center 203c are shifted.

  Therefore, even if the motors 101 and 201 are arranged on the base width center lines 100c and 200c, the compressors 103 and 203 are arranged at positions shifted from the base width center lines 100c and 200c, respectively. That is, since the centers of gravity of the compressors 103 and 203 deviate from the base width centers 100c and 200c, the girders constituting the bases 100 and 200 are also arranged at asymmetric positions with respect to the base width centers 100c and 200c, respectively. There is a need to.

  In the third embodiment shown in FIG. 10, the center of gravity 304G of each device on the drive machine installation area 304 is located on the upper side of the base width center line 300c. Similarly, in the third embodiment shown in FIG. 10, the center of gravity 305G of each device on the driven machine installation region 305 and the center of gravity 306G of each device on the auxiliary machine installation region 306 are represented by the base width center line 300c. The example located in the lower side is shown.

  Therefore, the main machine stiffening girder 321 is arranged in the drive machine installation region 304 so as to increase the rigidity above the base width center line 300c according to the center of gravity position 304G. That is, considering the gravity center position 304G of the drive machine installation region 304 where the drive machine is installed and the weight of the drive machine, the main machine stiffening girder 321 having an appropriate rigidity (dimension) is asymmetrical with respect to the base width center line 300c. Place in position. Thus, the main machine stiffening girder 321 is provided with a girder having a rigidity suitable for supporting the weight of the driving machine and the weight of the center of gravity 304G.

Further, in the driven machine installation area 305, the main machine stiffening girder 312c is arranged so as to increase the rigidity below the base width center line 300c according to the center of gravity position 305G. That is, considering the center of gravity position 305G of the driven machine installation area 305 where the driven machine is installed and the weight of the driven machine, the main machine stiffening girder 312c having the appropriate rigidity (dimension) is connected to the base width center line 300c. To asymmetrical positions.
Further, according to the center of gravity position 306G, the auxiliary machine stiffening girders 314 and 315 are arranged in the auxiliary machine installation area 306 so as to increase the rigidity below the base width center line 300c. That is, the girders 314 and 315 having rigidity suitable for supporting the center of gravity of the center of gravity position 306G and supporting the weight of the auxiliary machine are disposed at positions asymmetric with respect to the base width center line 300c.

  In this way, considering the respective gravity center positions 304G, 305G, and 306G and the weights of the driving machine, driven machine, and auxiliary machine, girders 321, 312c, 314, and 315 having appropriate dimensions are arranged at asymmetric positions. By doing so, the rigidity of the base 300 is improved and members such as extra girders can be reduced as compared with the case where girders are arranged at positions symmetrical to the base width center line 300c. Therefore, the weight of the base 300 can be reduced.

  Also in the structure of the base 300, the main girder 310 and the main machine stiffening girders 311 and 312 are installed in the drive machine installation area 304 and the driven machine installation area 305, respectively. Further, an auxiliary machine stiffening girder 313 is installed in the auxiliary machine installation area 306. The rigidity of the main machine stiffening girders 311 and 312 and the auxiliary machine stiffening girder 313 may be lower than the rigidity of the main girder 310. The rigidity of the main machine stiffening girders 321 and 312c and the auxiliary machine stiffening girders 314 and 315 may be lower than the rigidity of the main girder 310.

That is, the two main machine stiffening girders 112a are widened from each other in an oblique direction in a top view from the mounting position of the vibration isolator 109 below the compressor 103 toward the vibration isolators 107 and 108 of the main girder 110.

  Thus, the base 100A is configured such that the main machine stiffening girder 112a couples the vibration isolators 107, 108, and 109 that support the three points of the base 100A. Therefore, it is possible to realize the base 100A in which the rigidity in the XY plane direction (base 100A horizontal plane direction) of the driving machine installation area 104 and the driven machine installation area 105 and the torsion around the axis in the XY plane direction is further improved.

FIG. 12 is a bottom view of the rotating machine installation base 200A of Example 2 according to Example 4 of the present invention.
A rotating machine installation base 200A (hereinafter referred to as “base 200A”) of Example 2 according to Example 4 is provided with a main machine stiffening girder 212a. That is, the two main machine stiffening girders 212a have a width in an oblique direction when viewed from above from the mounting position of the vibration isolator 209 below the compressor 203 toward the vibration isolators 207 and 208 of each main girder 210. Stretching while spreading. The machine stiffening girder 212a is connected to each attachment location of the vibration isolator 207 and the vibration isolator 208.
The other configuration of the base 200A is the same as that of the base 200 of the second embodiment shown in FIGS. 7 to 9, and therefore, the same reference numerals are given and detailed description thereof is omitted.

  As a result, the base 200A is configured such that the main machine stiffening girder 212a couples the vibration isolators 207, 208, and 209 that support the three points of the base 200A. Therefore, it is possible to realize the base 200A in which the rigidity in the XY plane direction (base 200A horizontal plane direction) of the driving machine installation area 204 and the driven machine installation area 205 and the torsion around the axis in the XY plane direction is further improved.

FIG. 13 is a bottom view of the rotating machine installation base 300A of Example 3 according to Example 4 of the present invention.
The rotating machine installation base 300A of Example 3 according to Example 4 (hereinafter referred to as “base 300A”) is provided with a main machine stiffening girder 312a. That is, the two main machine stiffening girders 312a are directed from the attachment position of the vibration isolator 309 below the compressor 303 to the vibration isolator 307 and the vibration isolator 308 of each main girder 310, and are mutually spaced in an oblique direction in a top view. Stretching while expanding. The main machine stiffening girder 312a is connected to each attachment location of the vibration isolator 307 and the vibration isolator 308.

Since the other configuration of the base 300A is the same as that of the base 300 of the third embodiment, the same reference numerals are given and detailed description thereof is omitted.
Accordingly, the main machine stiffening girder 312a is configured to couple the three-point supported vibration isolators 307, 308, and 309 of the base 300A, so the XY plane between the drive machine installation area 304 and the driven machine installation area 305 It is possible to realize the base 300A having improved rigidity with respect to the load in the direction (base 300A horizontal plane direction) and torsion around the axis in the XY plane direction.

In the first to fourth embodiments, an active vibration isolation mount or a semi-active vibration isolation mount may be applied as the vibration isolation devices 107, 108, and 109. For example, the load sensor detects vibration and the electromagnetic actuator operates to cancel the vibration. According to this, the spring characteristics of the mount and the damper can be freely set, and the characteristics of the spring on the trailer 30 side and the spring on the base 100 side can be matched. At this time, the load sensor may be replaced with a strain sensor that measures strain or a position sensor that measures displacement of the position. Moreover, control can be changed according to road conditions, such as a bad road or a paved road.
Furthermore, the spring characteristics can be changed by the gas residual pressure in the closed section of the pipeline to be worked. For example, when the residual gas pressure is high, the rotation speed of the motor 101 can be reduced. However, when the residual gas pressure becomes low, it is necessary to increase the rotation speed of the motor 101 and increase the compression ratio. At this time, the occurrence of vibration also differs. For this reason, it is meaningful to change the spring characteristics in accordance with the residual pressure. Incidentally, you may make it change according to the rotation speed of the motor 101 instead of residual gas pressure.

In the first to fourth embodiments, various configurations have been described. However, these configurations may be appropriately combined.
In addition, the “both side surface portions in the drive machine installation area and the driven machine installation area” in the present invention includes the vicinity of both side surfaces of the bases 100, 200, 300, 100A, 200A, and 300A in the first to fourth embodiments. Shall be.
Note that the size of the base 100 can be determined according to the road regulations of the country of use.
While various embodiments of the present invention have been described above, various modifications and changes can be made within the scope of the present invention. That is, the embodiments of the present invention can be arbitrarily changed as appropriate without departing from the spirit of the invention.
