Description

  The present invention relates to a traverser for a railway vehicle that transports a temporary carriage that runs on a pull-in rail in a facility, for example, in order to inspect and repair the railway vehicle.

Generally, in order to perform overhaul inspection, repair, etc. of a railway vehicle, it is necessary to separate the car body and the bogie from the railway car. When the railway car enters, it is installed in the facility from the main car that runs on the main rail. The work of exchanging with a temporary carriage that runs on the pull-in rail is performed. Then, after completion of the overhaul and repair, an operation of replacing the temporary carriage worn on the railway vehicle with the main carriage is performed. In this case, the railcar traverser is used as a means for transferring the temporary carriage that has become unnecessary after the exchange between the main carriage and the temporary carriage to the return line. As shown in FIG. 9, the railcar traverser 100 is moved on the moving rail R <b> 2 toward the work station of the railcar and stopped at a position facing the railcar 101 waiting on the rail R <b> 1. Then, the tip end portion of the Tongrel 103 attached to the side end portion of the railcar traverser 100 is brought into contact with the upper surface of the rail R1. Then, the temporary carriages 102b and 103b of the railway vehicle 101 waiting on the rail R1 are brought into a state where they can move onto the floor rail 104 of the railway vehicle traverser 100 via the tongrel 103.
As shown in FIG. 10, the tongrel 103 is generally attached to a side end portion of a traverser so as to be able to be flipped up and its tip is tapered (see Patent Document 1).

JP-A-10-129482

  However, in the above-described Tongleil 103, as shown in FIG. 10, the slope of the rail surface 103S with respect to the upper and lower steps between the floor rail 104 of the railcar traverser 100 and the rail R1 on which the railcar 101 waits is made gentle, and the workpiece is removed. It is necessary to facilitate the movement, and the total length L must be long. For example, in order to facilitate the manual movement of the main carriage or temporary carriage as a work, the inclination angle θ of the rail surface 103S needs to be within about 6 to 7 °. The total length L is about 2.0 to 2.5 m or more. For this reason, when the tongrel 103 is turned from the flipped-up state (stored state) to the lying down state (use state), the leading end of the railway vehicle 101 waiting on the rail R1 and the leading end of the tongrel 103 are not interfered with each other. In this case, the railway vehicle 101 waiting on the rail R1 has to be separated from the railway vehicle traverser 100 by the above-mentioned total length L of the tongrel 103 or more. Therefore, the flip-up type Tongrail 103 has a problem that the vehicle standby space has to be increased due to the total length L of the Tongrel 103. In particular, in the case of a vehicle with a large amount of protrusion at the front end of the vehicle, such as the Shinkansen leading vehicle, it is difficult to vertically rotate the Tongrel 103 without interfering with the front end of the vehicle in the existing vehicle standby space. Met.

  The present invention has been made to solve such a problem, can contribute to space saving of the vehicle standby space, and the front end portion of the railway vehicle waiting on the rail does not interfere with the front end portion of the Tongle rail. An object of the present invention is to provide a railway vehicle traverser that can move a tongrel from a retracted state to a used state in a compact manner.

In order to achieve the above object, a railcar traverser according to the present invention comprises the following arrangement.
(1) A pedestal mounted with a workpiece and configured to be able to run on a moving rail, and a tongrel mounted on a side end of the pedestal so as to be retractable, and laid in a direction orthogonal to the moving rail. A railcar traverser for mounting and transferring the work on the rail on which the railcar is waiting on the base via the Tongrel.
The Tongleil has a tip portion formed so as to be rotatable in a substantially horizontal direction, and the tip portion is in contact with the upper end of the rail in use and is formed in a tapered shape in the vertical direction. And

In the present invention, since the tongrel is formed so that the tip portion thereof is rotatable in a substantially horizontal direction, the tip portion of the tongrel is maintained at a substantially constant height in the vertical direction at the tip portion of the tongrel. Can be rotated. Therefore, even if the railway vehicle is waiting at a position close to the railcar traverser, the Tongleil can be used from the retracted state while avoiding the interference with the leading end of the waiting railway vehicle. Can be moved to.
In addition, the tip of the Tongrel is in contact with the upper end of the rail where the railway vehicle waits during use and is tapered in the vertical direction. The front end of the Tongleil can pass through a gap formed between the lower end of the front end of the railway vehicle waiting on the top and the upper end of the rail. For this reason, the overall length of the Tongrel can be increased, and the slope of the rail surface of the Tongrel can be made gentle to facilitate the movement of the workpiece.
As a result, even if the railway vehicle is waiting at a position close to the railcar traverser in a narrow vehicle waiting space, the leading edge of the railway vehicle and the leading edge of the tongrail are not interfered with each other. It is possible to move from the retracted state to the in-use state so that the work on the rails on which the railway vehicle stands by can be mounted and transported on the base via the Tongrel.
Therefore, according to the present invention, it is possible to contribute to space saving of the vehicle standby space, the front end portion of the railway vehicle waiting on the rail and the front end portion of the tongrel pass each other, and the tongler is used from the retracted state. It is possible to provide a railcar traverser that can be moved to a state.

(2) In the railcar traverser described in (1),
The tongrel is formed in parallel with the rail from a base end portion connected to a side end portion of the base to a middle portion in a longitudinal direction, and the tip portion is centered on the middle portion. It is characterized in that it is formed so as to be able to rotate approximately 90 ° from a parallel state to an orthogonal state.

  In the present invention, the tongrel is formed in parallel with the rail on which the railway vehicle waits from the base end connected to the side end of the base to the intermediate portion in the longitudinal direction, and the tip is centered on the intermediate portion. Since the portion is formed so as to be able to turn approximately 90 ° from a state parallel to the rail to a state orthogonal to the rail, the weight of the tip side Tongler turning about 90 ° is reduced, and the base side It is possible to further simplify the support structure of the proximal end side Tongler connected to the end portion, the rotation mechanism of the distal end portion, and the like. It should be noted that it is preferable that the minimum clearance between the intermediate portion or the front end portion of the Tongrel and the front end portion of the railway vehicle standing on the rail is secured in the range of 100 to 150 mm when the Tongrel is stored.

(3) In the railcar traverser described in (1) or (2),
The tongrel is supported by the base in a state of being urged upward with respect to the side end of the base, and a predetermined distance is provided between the lower end of the tongrel and the upper end of the rail when no load is applied. A gap is formed.

  In the present invention, the tongrel is supported by the base in a state of being biased upward with respect to the side end of the base, and the lower end of the tongrel and the upper end of the rail on which the railway vehicle stands by when no load is applied. Since a predetermined gap is formed between the railcar, even if the tongrel vibrates somewhat in the vertical direction when the traverser for the railcar moves on the moving rail, the railcar waits at the lower end of the tongrail. Interference with the upper end of the rail can be prevented. The means for urging the Tongrel upward is applicable to an elastic body such as a spring, a pneumatic device such as a cylinder, or a hydraulic device, and is not particularly limited. Further, it is preferable that the predetermined gap formed between the lower end of the Tongleil and the upper end of the rail on which the railway vehicle stands by at no load is about 20 to 30 mm. If the predetermined gap is about 20 to 30 mm, it is possible to easily avoid the interference between the upper end of the Tongler and the lower end of the railcar waiting on the rail when the Tongrel is moved from the stored state to the used state. Because it can.

  According to the present invention, it is possible to contribute to space saving of the vehicle standby space, and the front end portion of the railway vehicle waiting on the rail and the front end portion of the Tongle rail pass without interfering, and the Tongle rail is changed from the stored state to the used state. A traverser for a railway vehicle that can be moved can be provided.

The temporary carriage 1 (1a, 1b) is mounted on the base 3 with the self-propelled temporary carriage 1a and the follower temporary carriage 1b connected in the front-rear direction.

  The base 3 is a cart body in which a floor board is joined to a frame body formed in a substantially rectangular shape, and a front end portion 31 and a rear end portion 32 that are positioned in the front-rear direction with respect to the traveling direction (the direction of the arrow T). A central portion 33 formed between a front end portion 31 and a rear end portion 32 is formed in a low floor shape. Traveling wheels 34 that travel on the moving rail 2 are disposed on both sides of the front end portion 31 and the rear end portion 32 formed in a raised floor shape. Drive motors 35 are coupled to the traveling wheels 34 disposed on both sides of the rear end portion 32. A battery 311 for supplying power to the drive motor 35 is mounted on the front end 31 of the base 3, and a hydraulic unit 321, an operation panel 322, and the like are mounted on the rear end 32 of the base 3. .

  In the central portion 33 of the base 3, a floor rail 332 for guiding the temporary carriage 1 (1a, 1b) is laid in a direction perpendicular to the traveling direction of the traverser 10 for the railway vehicle at substantially the same height as the floor surface. Has been. The gauge of the floor rail 332 is the same as the gauge of the rail 6 on which the railway vehicle 5 stands by. The floor rail 332 is laid in a straight line up to the side end 331 of the central portion 33 of the base 3.

  On the side end 331 of the base 3, a tongrel 4 formed with the same gauge as the floor rail 332 is attached. The tong rail 4 is formed so that the front end portion 43 is rotatable in a substantially horizontal direction, and the front end portion 43 comes into contact with the upper end of the rail 6 on which the railway vehicle 5 stands by during use, and is tapered in the vertical direction. Is formed.

<Detailed structure of Tongleil>
Next, the detailed structure of the tongrail 4 of the traverser 10 for the railway vehicle will be described with reference to FIGS. FIG. 4 shows a partially enlarged plan view of the Tongrel shown in FIG. FIG. 5 shows a side view of the B view shown in FIG. FIG. 6 is a cross-sectional view taken along the line CC shown in FIG. FIG. 7 is a cross-sectional view taken along the line DD shown in FIG.

  As shown in FIG. 4 to FIG. 7, the railway vehicle 5 is connected to the intermediate portion 42 (42 a) divided in the longitudinal direction from the base end 41 connected to the side end 331 of the base 3. It is formed in parallel with the waiting rail 6 and the tip 43 is approximately 90 from the state parallel to the rail 6 (used state) to the state orthogonal (stored state) with respect to the rail 6 around the intermediate part 42 (42a). ° It is designed to be rotatable. The distal end portion 43 rotates in a double-spreading manner toward the left and right outer sides of the rail. The tongrel 4 is supported by the base 3 while being biased upward with respect to the side end portion 331 of the base 3, and the bottom end 4B2 of the tongrel 4 and the top end 61 of the rail 6 are not loaded. A predetermined gap d is formed between the two.

  Specifically, the tongrel 4 is divided into two in the longitudinal direction at the intermediate end portion 42 (42a, 42b) into a base end portion side tongrel 4A and a tip end portion side tongrel 4B. When the proximal end side Tongrel 4A and the distal end side Tongrel 4B come into contact with each other at the intermediate portion 42 (42a, 42b), the rail vehicle 5 is extended in a straight line. In this case, the upper end (rail surface) 4A1 of the base end portion side Tongrel 4A and the upper end (rail surface) 4B1 of the front end portion side Tongrel 4B form an inclined surface having a gentle same gradient (inclination angle: about 6 °). To do.

  Further, in the intermediate portion 42 (42a, 42b) of the tongrel 4, the area of the abutting surface where the proximal end side tongrel 4A and the distal end side tongrel 4B abut on the intermediate portion 42 (42a, 42b). Abutment blocks 421 and 421 are provided for increasing the amount of the contact. In addition, when the base end part side Tongrel 4A and the front end part side Tongleil 4B contact | abut in the intermediate part 42 (42a, 42b), you may connect contact block 421,421 with pins. As a result, it is possible to prevent bending and the like during use of the Tongrel 4. Further, as will be described later, when the rod portion of the hydraulic cylinder 441 that rotates the front end side Tongler 4B expands and contracts, a method of controlling the bending at the time of using the Tongrel 4 by detecting the expanding and contracting end may be used.

  Moreover, the lower end 4A2 of the base end side side Tongrel 4A is formed in parallel with the upper end (rail surface) 4A1. The lower end 4B2 of the front end side Tongrel 4B is formed in a substantially horizontal shape and extends in a straight line with the rail 6 on which the railway vehicle 5 stands by, and is in a no-load state (indicated by a virtual line in FIG. 5). A predetermined gap d is formed between the upper end (rail surface) 61 of the rail 6 on which the railcar 5 waits by the urging force of spring members 448 and 455 which will be described later. The predetermined gap d is preferably about 20 to 30 mm. In order to adjust the predetermined gap d, an adjustment bolt 412 that comes into contact with the end surface of the base end portion 41 of the base end portion side Tongrel 4A is screwed to the side end portion 331 of the base 3. Note that the lower end 4B2 of the front end side Tongrel 4B is in a state where the temporary carriage 1 (1a, 1b) is transferred in a state where the lower end 4B2 extends in a straight line with the rail 6 on which the railway vehicle 5 stands by (in FIG. 5, a solid line). In the illustrated example, the spring members 448 and 455 are bent and come into contact with the upper end (rail surface) 61 of the rail 6.

  Further, a bearing bracket 444 is formed on the intermediate portion 42a of the base end side Tongrel 4A so as to protrude outward in the left and right directions of the rail, and the intermediate portion 42b of the tip end side Tongrel 4B is moved rearward when rotated. A projecting link arm 442 is formed. A link arm 442 is connected to the bearing bracket 444 via a hinge shaft 443 so as to be rotatable in the horizontal direction. A rod portion of the hydraulic cylinder 441 is connected to the rear end portion of the link arm 442. The hydraulic cylinder 441, the link arm 442, and the like constitute the turning mechanism 44 of the tip side Tongler 4B.

  In addition, a cylinder support member 446 that protrudes to the left and right outward of the rail is formed in the vicinity of the center in the longitudinal direction of the base end portion side Tongrel 4A. A case rear end portion of the hydraulic cylinder 441 is coupled to the cylinder support member 446 via a hinge shaft 445 so as to be rotatable in the horizontal direction. The distal end portion 43 of the distal end side Tongrel 4B is substantially from a state parallel to the rail 6 on which the railway vehicle 5 stands by centering on the hinge shaft 443 to a state perpendicular to the state by the expansion and contraction of the rod portion of the hydraulic cylinder 441. Rotate approximately 90 ° horizontally. Here, the state in which the tip end portion 43 of the tip portion side Tongrel 4B is parallel to the rail 6 on which the railway vehicle 5 waits corresponds to the use state of the Tongrel 4 and the tip portion 43 of the tip portion side Tongrel 4B. The state perpendicular to the rail 6 on which the railway vehicle 5 stands by corresponds to the retracted state of the Tongrel 4. In the retracted state of the Tongrel 4, it is preferable that the minimum gap between the intermediate portion 42 or the tip portion 43 and the tip portion of the railway vehicle 5 is secured about 100 to 150 mm.

  Further, the base end portion 41 of the base end portion side Tongrel 4A is connected to be pivotable in the vertical direction via a hinge shaft 411 formed on the side end portion 331 of the base 3. The hinge shaft 411 is supported by a third spring receiving bracket 447 described later. In addition, two reinforcing members 451 and 452 extending inward in the left and right directions are joined to the base end portion side Tongrel 4A so as to be separated from each other in the longitudinal direction of the rail. One reinforcing member 451 is joined in the vicinity of the base end portion 41, and the other reinforcing member 452 is joined in the vicinity of the intermediate portion 42a. A first spring receiving bracket 453 is joined to the reinforcing member 451 joined in the vicinity of the base end portion 41. A second spring receiving bracket 454 extends from the side end 331 of the base 3 below the first spring receiving bracket 453. A plurality of spring members 455 and 455 are mounted between the first spring support bracket 453 and the second spring support bracket 454. Adjustment bolts 456 and 456 that are in contact with the spring retainers 457 of the spring members 455 and 455 are screwed to the first spring receiving bracket 453, respectively.

  Further, a third spring receiving bracket 447 is provided at the side end 331 of the base 3 so as to extend below the cylinder support member 446 along the base end side tongrel 4A. A spring member 448 is mounted between the third spring receiving bracket 447 and the cylinder support member 446. An adjustment bolt 449 that abuts against the spring retainer 4481 of the spring member 448 is screwed onto the cylinder support member 446. The gap d between the lower end 4B2 of the front end side tongrail 4B and the upper end 61 of the rail 6 on which the railway vehicle 5 waits has a predetermined dimension (20 to 30 mm), and the traverser 10 for this railway vehicle The spring force of the spring members 455 and 448 described above is adjusted by the adjusting bolts 456 and 449 in order to suppress the vertical vibration of the entire Tongle rail 4 when the side Tongrel 4B is retracted and travels on the moving rail 2.

<Operation method of the traverser for this railway vehicle>
Next, an operation method of the railcar traverser will be described with reference to FIG. FIG. 8 shows an operational flowchart of the railcar traverser shown in FIG.

  As shown in FIG. 8, first, the railcar traverser 10 is moved from the original position to the railcar standby position (step: S1). Here, the traveling wheel 34 is rotated by operating the operation panel 322 and supplying power from the battery 311 to the drive motor 35. The original position is a position on the moving rail 2 where the railcar traverser 10 stands by and returns and temporarily stores the temporary carriage.

  Next, the railcar traverser 10 is stopped at the railcar standby position, and the tongue rail 4 is rotated from the retracted state to the used state (step: S2). Here, by operating the operation panel 322, the hydraulic pressure is supplied from the hydraulic unit 321 to the hydraulic cylinder 441, and the distal end portion 43 of the distal end side Tongrel 4B is rotated by approximately 90 °.

  Next, the temporary carriage 1 (1a, 1b) is mounted on the traverser 10 for the railway vehicle via the Tongler 4 (step: S3). Since the temporary carriage 1 (1a, 1b) is equipped with a self-propelled drive motor 12, the drive motor 12 is operated upon mounting.

  Next, after turning the tongrel 4 from the use state to the retracted state (step: S4), the traverser 10 for the railway vehicle is moved to the original position (step: S5). The tongue rail 4 is rotated by a hydraulic cylinder 441, and the traverser 10 for the railway vehicle is moved by a drive motor 35.

  Next, after turning the tongrel 4 from the retracted state to the in-use state (step: S6), the return line in which the temporary carriage 1 (1a, 1b) mounted on the railcar traverser 10 is laid in the original position. On the rail (step: S7). The temporary carriage 1 (1a, 1b) is transferred by a self-propelled drive motor 12. The temporary carriage 1 (1a, 1b) transferred onto the rail of the return line is transported for mounting on the railway vehicle 5 to be newly arrived and subjected to overhaul inspection or repair.

Next, after turning the tongrel 4 from the use state to the retracted state (step: S8), the traverser 10 for this railway vehicle is put on standby at the original position (step: S9).
As described above, by operating the railcar traverser 10, even if the railcar 5 is waiting at a position close to the railcar traverser 10 in the existing narrow vehicle standby space, the railcar 5 The tip part and the tip part 43 of the Tongle rail 4 pass each other without interfering with each other, and the Tongle rail 4 is moved from the retracted state to the used state, and the work on the rail 6 on which the railcar 5 waits (for example, the temporary carriage 1) It can be mounted on the base 3 via the tongue rail 4 and transported without difficulty.

<Effect>
As described above, according to the railcar traverser 10 according to the present embodiment described in detail, the tip portion 43 of the tongrel 4 is formed so that the tip portion 43 is rotatable in a substantially horizontal direction. The top end 43 of the Tongrel 4 can be rotated while maintaining the height in the vertical direction at substantially constant. Therefore, even if the railway vehicle 5 stands by at a position close to the railcar traverser 10, while avoiding the interference of the distal end portion 43 of the tongrail 4 with the distal end portion of the railway vehicle 5 waiting, the tongrail 4 Can be moved from the storage state to the use state.
Further, the tip 43 of the tongrel 4 is in contact with the upper end 61 of the rail 6 on which the railcar 5 waits during use, and is formed in a tapered shape in the vertical direction. When moving to the rail 6, the tip 43 of the Tongle rail 4 can pass through a gap formed between the lower end of the tip of the railway vehicle 5 waiting on the rail 6 and the upper end 61 of the rail 6. Therefore, the entire length of the Tongrel 4 can be formed long, and the gradient of the rail surface of the Tongrel 4 can be made gentle to facilitate the movement of the work 1 (main carriage or temporary carriage).

  As a result, even if the railway vehicle 5 stands by at a position close to the railcar traverser 10 in the existing narrow vehicle waiting space, the leading end portion of the railway vehicle 5 and the leading end portion 43 of the tongrel 4 interfere with each other. Without passing, the Tongle rail 4 is moved from the retracted state to the used state, and the work on the rail 6 on which the railcar 5 waits (for example, a temporary carriage) is easily mounted on the base 3 via the Tongle rail 4. And can be transported.

  Therefore, according to the present embodiment, it is possible to contribute to space saving of the vehicle standby space, and the front end portion of the railway vehicle 5 waiting on the rail 6 and the front end portion 43 of the tongrel 4 can pass each other without interference, It is possible to provide a railcar traverser 10 that can move 4 from a retracted state to a used state.

  Further, according to the present embodiment, the tongrel 4 is formed in parallel with the rail 6 on which the railway vehicle 5 waits from the base end portion 41 connected to the side end portion 331 of the base 3 to the intermediate portion 42 in the longitudinal direction. In addition, since the distal end portion 43 is formed to be rotatable about 90 ° from a state parallel to the rail 6 to a state orthogonal to the rail 6 around the intermediate portion 42, the distal end portion rotated about 90 °. By reducing the weight of the side Tongrel 4B, it is possible to further simplify the support structure of the base end side Tongler 4A connected to the side end 331 of the base 3 and the rotation mechanism of the front end 43. it can.

  In addition, since the minimum gap between the intermediate portion 42 or the tip portion 43 of the Tongrel 4 and the tip portion of the railway vehicle 5 waiting on the rail 6 is secured in the retracted state of the Tongrel 4 about 100 to 150 mm. Even when the railway car traverser 10 and the railway vehicle 5 waiting on the rail 6 pass each other, even if the Tongleil 4 slightly vibrates in the lateral direction, the intermediate part 42 or the tip part 43 of the Tongleil 4 is on standby railway. Interference with the front end portion of the vehicle 5 can be prevented.

  Further, according to the present embodiment, the tongrel 4 is supported by the base 3 while being biased upward with respect to the side end 331 of the base 3, and the bottom end of the tongrel 4 (when no load is applied). 4B2) and the upper end 61 of the rail 6 on which the railway vehicle 5 waits, a predetermined gap (about 20 to 30 mm) d is formed, so that the railcar traverser 10 moves on the moving rail 2 Even if the tongrel 4 vibrates to some extent, the lower end (4B2) of the tongrel 4 can be prevented from interfering with the upper end 61 of the rail 6 on which the railcar 5 is waiting. Further, since the predetermined gap is about 20 to 30 mm, the upper end (4B1) of the Tongle rail 4 interferes with the lower end of the railway vehicle 5 waiting on the rail 6 when the Tongle rail 4 is moved from the retracted state to the used state. Can be easily avoided.

As mentioned above, although the railcar traverser 10 of this embodiment was demonstrated in detail, this invention is not limited to this, A various change is possible in the range which does not deviate from the meaning.
For example, in the present embodiment, one set of the Tongrel 4 is attached to the side end portion 331 on one side of the base 3, but this is not necessarily limited thereto. For example, two sets of the tongrel 4 may be attached to the side end portions 331 on both sides of the base 3.
