Description

  The present invention relates to a track-type traffic system that travels a vehicle having traveling wheels made of rubber tires or the like on a predetermined track, and has traveling guide wheels on both sides of the vehicle. Reliable and simplified that allows the vehicle to travel safely and reliably on an X-shaped branch road formed by crossing tracks, using a side guide system that is guided by guide rails provided on both sides The present invention relates to a configuration of a branching device that has an improved configuration and improved ease of assembly and maintainability.

  Unlike a railroad vehicle that runs on rails, a rubber tire that is a running wheel is usually used for a vehicle of a track-based new transportation system that runs on a predetermined track with wheels made of rubber tires and is automatically driven unattended. A steering wheel for steering is provided to turn along a predetermined track, and the vehicle is mechanically steered by contacting and guiding the guide wheel on a guide rail provided on the track side. And running.

As a form of the branch path on which the track vehicle changes the traveling track, for example, there are a Y-shaped branch path as shown in FIG. 6A and an X-shaped branch path as shown in FIG. 6B.
Among these, for example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-178911) discloses a branching mechanism when a vehicle travels on a Y-shaped branch road. In this apparatus, a guide rail is provided on a track, and a vehicle is steered by guiding a travel guide wheel provided on the vehicle side to the guide rail. Then, on the Y-shaped branch road, the guide rail on the side of the branch road where the vehicle does not travel is moved laterally by a rolling machine or the like to release the engagement with the travel guide wheels, so that the vehicle enters the other branch road. It is configured.

Further, a branching device when a relatively high-speed train travels on an X-shaped branch road is disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 6-264403).
FIG. 7 is a skeleton diagram of the branching device. The branching device has two single-sided branching machines 03, 04, 05, 06 facing upstream lines 01, 01 ′ and downstream lines 02, 02 ′, respectively. These branching machines are each converted to a conversion width (W) by a rotating arm with a speed reducer provided on the ground side base to form an X shape, and a rotating girder 07 is installed between them to provide a smooth transition of the vehicle Is possible. Reference numeral 022 denotes a fixed girder which is disposed at the tip of each branching machine and is left to secure a gap L2 for inserting the rotating beam 07 when the branching machine forms an X shape.

In Patent Document 3 (Japanese Patent Laid-Open No. 54-51106), as in Patent Document 1, guidance is provided in a branching device that steers a vehicle with a guide rail and traveling guide wheels when traveling on a Y-shaped branch road. A system in which a rail is configured by a support bar that can be raised and lowered is disclosed.
Patent Document 4 (Japanese Patent Application Laid-Open No. 57-187401) discloses a branching device for steering a vehicle with a guide rail and traveling guide wheels when traveling on a Y-shaped branch road, as in Patent Document 1. A system is disclosed in which two roadside guide rails can be moved up and down by a rotating crankshaft.

  Patent Document 5 (Japanese Patent Application Laid-Open No. 7-150503) discloses a branching device that steers a vehicle with a guide rail and traveling guide wheels when traveling on a Y-shaped branch road, as in Patent Document 1. A system is disclosed in which a guide rail on one side of a straight path that becomes an obstacle when sending from a straight path to a branch path can be rotated 90 degrees in a horizontal direction from an upright state.

However, in the method of guiding the traveling guide wheels by the guide rails as disclosed in Patent Document 1 and steering the vehicle, the guide rails provided on the respective tracks cross each other on the X-shaped branch road, which is effective. No branching device has been realized.
Further, the branch device for the X-shaped branch path disclosed in Patent Document 2 requires position adjustment by moving the branching machines 03 to 06 and rotating the rotating girder 07 having a heavy weight. It takes a long time to change the route, and it is not suitable when frequent course changes are required.

  Further, the lifting means disclosed in Patent Documents 3 to 5 do not take into account the rotationally driven portion or the clearance facing the fixed rail surface. If these are not taken into consideration, the entire apparatus or the entire branch path must be removed for replacement during actual assembly or maintenance, and welding and other complicated adjustment work are also required during assembly.

  Further, when comparing the Y-shaped branch path and the X-shaped branch path, as shown in FIG. 6, the Y-shaped branch path has a much longer branch point than the X-shaped branch path, and the time required for changing the branch path is long. And the speed of the travel at the branch point is limited, so that there is a problem that the speed limit section becomes long. Therefore, the Y-shaped branch road cannot be adopted near a station where the operation cycle becomes long and the vehicle frequently starts and stops or where the track is curved.

As described above, in the new traffic system that employs the mechanical steering system on the branch road using the guide rail and the traveling guide wheel as disclosed in Patent Document 1, the branch device on the X-shaped branch road has been used so far. However, such a mechanical steering system using a guide rail has a strong resistance to a lateral force against the vehicle, and the center part of the track can be made flat. There is an advantage that passengers are easy to evacuate by walking on the track, such as when the car stops in an emergency.
Therefore, it is desired to realize a branching device that can safely and reliably travel on an X-shaped branch road with such a mechanical steering system and that is easy to assemble and reduces work during maintenance. It was.

(B) is an IIb arrow view in FIG. (A), (c) is an IIc arrow view in FIG. (A), (d) is an IId arrow view in FIG. (E) is the IIe arrow line view in figure (d).
1-2, A and B are trajectories that intersect with each other to form an X-shaped branch path. On both sides of the tracks A and B, an outer guide rail 11a and an inner guide rail 11b are installed in order to guide the traveling guide wheels 2 projecting from both side walls of the vehicle 1 from both sides. In addition, on the upper part of the guide rails 11a and 11b, a train line 12 for supplying electric power to the traveling vehicle 1 is laid. A portion 17 is provided. Reference numeral 3 denotes a traveling wheel of the vehicle 1 made of rubber tires or the like.

13a and 13b are auxiliary rails provided so as to be capable of moving up and down on the crossing plane X. The guide rails provided on both sides of the tracks A and B are extended from the outer guide rail 11a so as to be connected to the line of the outer guide rail 11a. A pair of auxiliary rails 13 a arranged on the line and facing each other are simultaneously raised to constitute guide rails for the guide wheels 2 arranged on both sides of the vehicle 1.
Reference numeral 14 denotes an arm having one end connected to the auxiliary rails 13a and 13b and supporting the auxiliary rail so that the auxiliary rail can be moved up and down. The other end of the arm 14 is disposed on the vehicle running surface Y on the tracks A and B or on the periphery of the track. It is rotatably installed by a support shaft 14a embedded below the running surface Y.

  Reference numeral 15 denotes a turning machine having a conventionally known structure installed around the X-shaped branch path, and its output shaft 15a is connected to a rotating shaft 16a arranged in parallel with the auxiliary rail 13a. As shown in FIG. 2C, the output shaft 15a is reciprocated by the rack and pinion mechanism in the rotary machine 15, and is connected to the rotating shaft 16a via the lever 21 to rotate the rotating shaft 16a. On the other hand, 15b is a lock rod for fixing the rotation shaft 16a after the rotation shaft 16a rotates by a set angle.

In the apparatus of the first embodiment, as shown in FIG. 1, when the vehicle 1 approaches the X-shaped branch path on the track B, the vehicle 1 is arranged so as to block the running surface of the track A at the intersection plane X. It is necessary to raise the auxiliary rail 13a and lower the auxiliary rail 13b disposed on the track B. This lifting mechanism will be described with reference to FIG.
In FIG. 2, since the output shaft 15a of the rotary machine 15 is connected to the rotating shaft 16a via the lever 21, the reciprocating motion of the output shaft 15a rotates the rotating shaft 16a. A crank 22 is attached to the rotation shaft 16 a on the auxiliary rail 13 a side, and the crank 22 is connected to the arm 14.

The rotating shaft 16 a is connected to the rotating shaft 16 b on the auxiliary rail 13 b side via the universal joint 24, and the rotating motion of the rotating shaft 16 a is transferred to the rotating shaft 16 b via the universal joint 24. Communicated. A crank 23 is attached to the rotating shaft 16b, and the crank 23 is connected to the arm 14 on the auxiliary rail 13b side.
The cranks 22 and 23 change the rotational motion of the rotational shafts 16a and 16b to a reciprocating motion in the vertical direction to raise and lower the arm 14, but the cranks 22 and 23 are provided with phases shifted by 180 degrees from each other. Therefore, when one arm 14 is raised, the other arm 14 is lowered.

In FIG. 2B, the auxiliary rail 13a is placed on a cradle 25 embedded in the traveling surface Y when lowered, and the upper surface of the lowered auxiliary rail 13a coincides with the traveling surface Y. It has become. A guide surface 13c receives the guide wheel 2.
When the rotating shaft 16a is rotated forward in this way, the auxiliary rail 13a is raised, and conversely, the auxiliary rail 23b is lowered, and when the rotating shaft 16a is rotated backward, the auxiliary rail 13a is lowered and conversely. The auxiliary rail 23b rises. Here, circular movement in one direction is referred to as “rotation”, and circular movement in both forward and reverse directions is referred to as “rotation”.

Reference numeral 26 denotes a shielding plate attached at the same height as the upper surface of the arm and the auxiliary rail at the joint between the arm 14 and the auxiliary rails 13a and 13b. A bearing 27 is installed to support the rotating shafts 16a and 16b. As shown in FIG. 2D, the rotary shafts 16a and 16b in the vicinity of the bearing 27 have a stepped portion 16c, and a spacer 28 is inserted into the stepped portion 16c. It is fixed in the axial direction. The spacer 28 is divided into two and can be attached to and detached from the rotating shaft.
Further, as shown in FIG. 2 (e), the bearing 27 is also configured so that the portion supporting the rotating shaft can be divided. The length b of the spacer 28 is set to be longer than the drawing allowance a between the rotating shafts 16a and 16b and the universal joint 24 (a <b).

In the apparatus of the first embodiment, when the vehicle 1 travels on the track B and approaches the X-shaped branch road, the auxiliary rail 13b disposed so as to block the track on which the vehicle 1 travels is lowered, and the vehicle 1 raises the auxiliary rail 13a arranged along the track B along which the vehicle 1 travels. The raised auxiliary rail 13a functions as a guide rail for the guide wheels 2, and the lowered auxiliary rail 13b forms a running surface Y.
In the first embodiment, if the auxiliary rail 13a is raised by the structure shown in FIG. 2, the auxiliary rail 13b adjacent to the auxiliary rail 13a is automatically lowered, so that the vehicle 1 uses the auxiliary rail 13a as the guide rail. Since the guide wheel 2 can be guided as follows, it is possible to pass through the intersection plane X without hindrance.

  When removing the rotary shafts 16a and 16b for maintenance, inspection, etc., first remove the split portion 27a of the bearing 27, remove the cranks 22 and 23 from the rotary shaft, and then remove the spacer 28 to remove the rotary shaft. 16 a and 16 b can move in the axial direction by the length b of the spacer 27, and can be pulled out from the fitting portion with the universal joint 24.

According to the first embodiment, the vehicle 1 can travel on the X-shaped branch road safely and reliably with such a simple device configuration. In the first embodiment, the lifting means of the auxiliary rails 13a and 13b are connected by the universal joint 24, and the raising and lowering movements of the auxiliary rails 13a and 13b are interlocked. It is only necessary to install the apparatus. In this embodiment, the apparatus configuration can be further simplified.
Further, since the auxiliary rail 13b is lowered when the auxiliary rail 13a is raised, the auxiliary rail 13b also has its own weight as a counterweight, and the load on the drive source can be reduced.

  Further, in the X-shaped branch road, as shown in FIG. 1, the train line 12 is interrupted at the intersection plane X, but according to the first embodiment, the vehicle length of the vehicle 1 is longer than the intersection plane X. At least one power receiving unit 17 can maintain contact with the train line 12, and therefore can always receive power even on an X-shaped branch path.

Further, the bearing 27 and the cranks 22, 23, etc. that require maintenance such as refueling and replacement, are located below the shielding plate 26 that forms the same plane as the vehicle traveling surface Y, at a position away from the easily traveling surface Y. Because it is arranged, maintenance and inspection of the equipment becomes easy. Further, the removal of the rotating shafts 16a and 16b is extremely easy only by removing the spacer 28.
The auxiliary rails 13a and 13b may be moved up and down separately without connecting the lifting means of the auxiliary rails 13a and 13b with the universal joint 24. In this case, four turning machines are required, but a mechanism for interlocking the lifting means of the auxiliary rails 13a and 13b can be omitted.
Moreover, you may rotate the rotating shaft 16a via a reduction gear using an electric motor etc. instead of the rolling mill 15. FIG.

The rotary shaft 31 is connected to the output shaft 15a of the above-described turning machine 15 via the lever 21 to convert the reciprocating motion of the output shaft 15a into the rotary motion of the rotary shaft 31. Reference numeral 15b denotes a lock rod for fixing the rotating shaft 31 after rotating it by a set angle.

The rotary shafts 31 and 32 are supported by bearing seats 34, 35 and 36, 37, respectively, and are connected to each other by a connecting rod 33 via links 38, 39. The rotation shafts 31 and 32 are connected to the auxiliary rails 13a or 13b via links 40 or 41, respectively.
In the second embodiment, one switch 15 (four in total) is installed for one auxiliary rail 13a, 13b.

In FIG. 5, reference numeral 42 denotes an adjustment rail which is configured separately from the auxiliary rail body 13a and has a fitting groove 42a slidably fitted to the fitting piece 43 protruding from the auxiliary rail body 13a. The position relative to 13a can be adjusted. After adjusting the position with respect to the auxiliary rail 13a, it is fixed to the auxiliary rail rail 13a with a bolt 45 in the long hole 44.
With the adjustment rail 42, the tip end portion of the auxiliary rail 13a after installation can be adjusted to an appropriate position with respect to the auxiliary rail 13 and the outer guide rail 11a.

  In the apparatus of the second embodiment, when the switch 15 is operated and its output shaft 15a is moved in the axial direction, the rotary shaft 31 connected to the output shaft 15a and the rotary shaft 31 via the connecting rod 33 are connected. The connected rotation shafts 32 rotate simultaneously. As a result, the links 40 and 41 connected to the rotating shafts 31 and 32 rotate around the rotating shafts 31 and 32, so that the auxiliary rails 13a and 13b connected to the links 40 and 41 are moved up and down. The auxiliary rail becomes a guide rail when it is raised and guides the guide wheels 2, and when it is lowered, it becomes the same height as the running surface Y and forms a part of the running surface.

According to the apparatus of the second embodiment, the vehicle can travel safely and reliably on the X-shaped branch road with a simple configuration. Even if the train line 12 is interrupted at the intersection X, the entire length of the vehicle 1 is longer than the width of the intersection X, so that one of the power receiving units 17 arranged on the left and right sides of the vehicle 1 is always on the train. Contact with the line 12 can be maintained, and the vehicle 1 will not be disturbed.
In the second embodiment, the rotary shaft 31 may be driven via a speed reducer with an electric motor or the like instead of the switch 15.

Further, when the auxiliary rail 13a is installed, it is continuous as much as possible so that the tip portion does not hit the auxiliary rail 13b, the outer guide rail 11a, etc. However, in the present embodiment, the position of the tip of the auxiliary rail 13a can be adjusted by the adjustment rail 42, so that the position of the tip of the auxiliary rail 13a is adjusted to an optimum position. be able to.
Further, as shown in FIG. 5 (b), since the adjustment rail 42 is provided with the step portion 42b, the step at the portion of the guide surface 13c where the travel guide wheel 2 contacts can be kept to a minimum.

  As described above, according to the present invention, in a track-type traffic system having a mechanical steering device composed of a travel guide wheel provided on a vehicle and a guide rail provided on a track side, the vehicle has an X-shaped branch. When traveling on a road, it is possible to realize a highly reliable branching device that can travel safely and reliably with a simple configuration, and that can improve ease of assembly and maintainability.
