When the replacement of the ballast is completed, the excavator is moved from the roadbed of the vehicle along the guide rails, and is lifted and stored on both sides of the vehicle.

The following effects are obtained by such an operation. (1) Since the ballast is supplied immediately after the ballast is excavated, the space after the ballast is excavated does not become large, and temporary receiving of rails by jacks or the like becomes unnecessary. (2) Since the excavator rotates up and down with respect to the rail and can be inserted from above the ballast ballast obliquely and starts excavation, there is no need for extra excavation for the excavator to enter the ballast. (3) The shape of the excavator is not a shape having a full width of the roadbed from one side of the conventional vehicle, but a shape excavating from both the left and right sides of the vehicle. The structure of the device can be simplified. (4) Since the excavator can rotate with respect to the vehicle and move up and down in the vertical direction and is stored on both sides of the vehicle, the amount of protrusion from the vehicle width is reduced.

The ballast 9 collected by the excavation is sucked through the suction port 2a, the suction pump 2c is introduced through the suction hose 2b, and further discharged from the discharge side to the ballast collection tank 6 through the discharge hose 2d.

The attitude adjusting device 3 operates in the following manner in order to adjust the attitude so that the excavator 1 and the suction device 2 can perform optimal excavation and suction of the ballast with respect to the ballast 9. FIG. 9 is a plan view showing the posture of the excavator 1 in the middle of being pulled out to the left and right with respect to the traveling direction on the rail 12 and the posture after the overhang. As shown in FIG. 9, when the hydraulic pressure generated by a hydraulic pump or the like (not shown) is fed to the contraction side of the cylinder 3φ, the turning link 3n turns counterclockwise around the turning center axis 3m, and the excavator Reference numeral 1 indicates that the connecting plate 3L directly connected to the rotating link 3n rotates clockwise about the rotating central axis 3m as shown by an arrow. At the same time, when the excavator 1 rotates and comes to a position orthogonal to the rail 12, the rotation is stopped. Next, when the excavator 1 comes to a position orthogonal to the rail 12, ballast excavation is performed in the following manner.

When oil pressure generated by a hydraulic pump or the like (not shown) is supplied to the extension side of the cylinder 3a, the cylinder 3a shown in FIG. 3 is extended, and the connecting plate 3e is centered on the pin 3g.
Rotates counterclockwise. Further, when the cylinder 3a is contracted, the cylinder 3a rotates in the opposite clockwise direction. As described above,
The rough adjustment of the excavating device 1 and the suction device 2 is performed by operating the guide rail 7 to vertically move the mounting base 3d on which the above-described connecting plate 3e is mounted relative to the vehicle.

That is, as shown in FIGS. 3, 4, and 6,
Rollers 3i, 3i 'are applied to the outer peripheral surface and both side surfaces of the guide rail 7.
By driving the output shaft 3k of the electric motor 3j mounted so as to mesh with the internal teeth 7a mounted on the inner peripheral surface of the guide rail 7, the drive shaft 3k meshed with the internal teeth 7a meshes. The guide rail 7 revolves around the center of curvature while rotating. Therefore, the mounting base 3d also revolves up and down with respect to the vehicle 5 in the same manner. In FIG. 3, when the drive shaft 3k rotates clockwise, the state where the mounting base 3d moves upward with respect to the vehicle is indicated by an arrow.

Next, the vehicle 5 is operated by the operation of the posture adjusting device 3.
In contrast, three types of cases in which the attitude of the roadbed changer is changed according to each work are shown below. (A) FIG. 7 is a plan view showing a state during traveling movement in which the excavator is stored within the vehicle width, and FIG. 8 is a front view of FIG. The situation when the vehicle is forwarded will be described with reference to both figures. Guide rail 7
In response to this, the mounting base 3d is caused to move upward and the cylinder 3φ
When the excavator 1 is pulled up from the surface of the ballast ballast 9 and the cylinder 3a is further extended and the turning link 3n is turned counterclockwise, the excavating device 1 turns in the direction of the arrow shown in the figure and the vehicle recess. 5a, the amount of protrusion from the vehicle 5 is minimized, and the vehicle 5 can travel. (B) FIG. 9 is a plan view showing the posture during and after the excavator is pulled out to the left and right positions with respect to the rail traveling direction, and FIG.
0 is an EE sectional view of FIG. In both figures, the state immediately before the start of excavation will be described. The excavator 1 is pivotally installed above the guide rail 7 similarly to the state shown in the above (a),
When the cylinder 3d is contracted and operated in this state, the turning link 3n turns clockwise, so that the excavator 1 integrated with the turning link 3n rotates clockwise about the turning center axis 3m as shown by an arrow in the figure. Then, the rotation is stopped in a posture orthogonal to the rail 12 as shown on the left side of FIG. (C) FIG. 11 is a front view showing a state at the start of excavation of a ballast ballast, in which the mounting base 3d is set at an intermediate position with respect to the guide rail 7, and the cylinder 3a is shortened from the above state (b). Then, the tip of the excavator 1 is inserted into the ballast 9 below the rail 12, and the excavator 1 and the suction device 2 start excavation and recovery. (D) FIG. 2 shows a situation during the excavation work. The mounting base 3 d is set at the lower part of the guide rail 7 and the cylinder 3
a is shortened, the excavator 1 is positioned horizontally with respect to the floor 10, excavated by the excavator 1, and sucked by the suction device 2.

When the excavation of the ballast 9 has been completed by the above operation, the excavator 1 and the suction device 2 are moved in the vehicle forward posture by the reverse of the operations (a), (b), (c) and (d). To complete the series of operations.

Next, when a series of excavation work is completed, as shown in FIG. 1, the ballast 9 under the excavated rail 12 is removed, and a space 16 after excavation is formed. Here, the operation of the supply device 4 for supplying a new ballast to the space 16 will be described below.

The excavated and recovered ballast is classified into a ballast that can be reused by a ballast classifier (not shown).
The newly replenished ballast is stored in the ballast supply tank 4a on the excavation and recovery vehicle 13c. Here, when the suction pump in the supply device 4 (not shown) is operated, the supply ballast is supplied by the supply hose 4b to the hopper 4c. The new ballast is sequentially sent out by the multi-stage conveyors 4d, 4e, 4f, and 4g, and is supplied to the space 16 and filled back.

When the ballast replacement is completed as described above, the vehicle advances in the traveling direction R of the vehicle shown in FIG. 1, and a new ballast ballast replacement operation is performed. In FIG. 1, the width of the bucket 1b of the excavator 1 is the width of the sleeper 8, but if the width of the bucket 1b is larger than the width of the sleeper 8, the work efficiency is further improved. The supply vehicle 13b is equipped with a power unit 14, which is a drive source of each device, as shown in FIG.

The configuration of the embodiment described above is summarized as follows. (1) An excavator 1 for excavating a ballast 9 for a ballast, a collecting device for collecting ballast after excavation, and a posture adjusting device 3 for adjusting the posture of the excavator 1 for ballast excavation in an optimal state. As a supply device 4 for supplying the ballast to the space after the ballast excavation, the vehicle is mounted and connected to each vehicle, and the ballast is immediately supplied after the ballast excavation. (2) An attitude adjusting device 3 composed of a hydraulic cylinder, a link, and the like is installed so that the ballast excavator 1 can be turned 90 ° with respect to the rail 12 and vertically moved up and down. Is inserted into.
Further, the chain cutter main body 1a is arranged so that the cutter rotates vertically with respect to the rail 12. (3) Two excavators 1 are installed in the left-right direction of the vehicle, and the ballast is replaced by half the width of the roadbed, so that the length of the cutter body of the excavator is short. (4) Since the excavator can be turned 90 ° with respect to the rail and moved up and down in the vertical direction, the excavator is stored in the vehicle recess during traveling and has a structure that does not protrude beyond the vehicle width.

With this configuration, the present embodiment has the following advantages. (1) Since the ballast under the sleeper which needs to be replaced in the ballast 9 is excavated and sucked and collected, auxiliary work such as temporary support of the rail 12 is unnecessary, and the working efficiency is greatly improved as compared with the conventional method. (2) Since the excavator 1 is inserted into the ballast from diagonally above the rail 12 in the left-right direction and excavates, hand digging by an operator for inserting the excavator 1 becomes unnecessary. (3) The vehicle travels only when the vehicle is moving, and when the ballast is excavated, the vehicle is stopped. Therefore, the structure is simple and the required power is small. In addition, the excavator 1 is constructed symmetrically in the left and right directions with respect to the vehicle, and excavates at the same time, so that a balance can be obtained at the time of excavation. (4) An external force can be applied to the vehicle at the same time from both lateral directions. In this case, the external force is simply one direction, and the structure corresponding to the external force is simplified. (5) The excavator 1 is extended by the cylinder and the link mechanism in the lateral direction with respect to the rail traveling direction during ballast excavation, and is folded 90 ° from this state during traveling movement to be within the vehicle width. By being stored, the protrusion is reduced, and safety during traveling is ensured.

Here, the connecting rod 3q (shown in FIG. 7) connects and supports the turning center shaft 3m attached to the left and right positions of the vehicle 5, and the excavating device 1 of the cantilevered roadbed changer having a cantilever structure with respect to the vehicle 5. The suction device 2 is configured to be structurally strong.

[0040]

As specifically described above, according to the present invention, a guide rail in which an excavator mounted on a vehicle is mounted on both side surfaces of the vehicle, a mounting base that moves up and down along the guide rail, and this mounting base The ballast excavated by supporting it with the connecting plate connected to the ballast is collected by suctioning the ballast with a suction device, and the ballast supply device supplies the ballast to the empty space after excavation. Is played. (1) Since only the ballast under the sleeper that needs to be replaced is excavated and sucked in the ballast, auxiliary work such as temporary support of rails is not required, and the working efficiency is greatly improved as compared with the conventional method. (2) Since the excavator is automatically inserted from both sides of the vehicle, hand digging for insertion by an operator is not required. (3) The vehicle travels only when the vehicle is moving and stops when the ballast is excavated. Therefore, the structure is simple and the required power is small. The excavator is configured symmetrically in the left-right direction with respect to the vehicle and excavates at the same time, so that a balance can be obtained during excavation. In addition, the external force can be applied to the vehicle simultaneously from both lateral directions, and the structure corresponding to the external force is simplified. (4) The excavator is extended in the left and right direction with respect to the rail traveling direction during ballast excavation, and is stored within the vehicle width during traveling movement, so that protrusion is reduced, and safety during traveling is ensured.
