Abstract

PURPOSE:To exhibit wedge effect definitely and hold the wheels of a railway carriage. CONSTITUTION:A wheel stopper arm 57 is supported with a hinge pin 60 at a lateral position of a rail 12 for railway carriage. A wedge 57a, which is fitted into a corner formed by the top of the rail and a tread of the hinge pin 60, is installed to the tip of the wheel stopper arm 57. By slanting the axial line of the hinge pin 60 downward at the front of the corner or laterally to the corner, the wedge 57a at the tip of the arm 57 moves on a plane slanted forward or upward laterally between a wheel stopper position on the rail 12 and a retracted position lateral to the rail.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel stop device for a rail vehicle and a rail vehicle three-dimensional storage facility equipped with the wheel stop device.

[0002]

2. Description of the Related Art As a proposal for a three-dimensional storage facility for railway vehicles, a hangar having a multi-layered structure in which a storage unit having rails for railway vehicles is provided on each floor, and a vehicle elevating device equipped with an elevator for a railway vehicle are arranged in front and rear. Is known (see Japanese Patent Publication No. 54-6798). In this one, a loading and unloading line of a railway vehicle extends across the vehicle elevating device across from the hangar, and a railway vehicle is loaded on the elevator of the vehicle elevating device from the loading and unloading line, and the elevator is mounted on the elevator. The vehicle is moved up to the planned storage floor of the hangar and the vehicle is stored in the storage section on the floor by self-propelled.

In the case of the above-mentioned three-dimensional storage facility, since the railway vehicle is stored in the storage section by self-propelled from the elevator, the driver operates the brake on the elevator to prevent accidental movement of the railway vehicle. Although it is possible to prevent it, it is necessary to prevent the stored railway cars from running accidentally due to an earthquake etc. in the hangar. There are similar requirements for equipment (the yard).

A movable wheel stopper device is generally known as a means for preventing such accidental movement of a railway vehicle. For example, a wheel stopper arranged between a pair of parallel rails is made to move laterally on the rail by interlocking with a related rolling device.

[0005]

However, in the case of the above-mentioned movable wheel stopper, if the stop position of the wheel on the rail shifts back and forth, the wheel stopper hits the side surface of the wheel and does not move on the rail. Even if it moves on the rail, there is a concern that a relatively wide gap will be created between the wheel and the wheel, and the desired wheel stopping function may not be fully exerted.

Further, when the movable wheel stopper is not sufficiently reliable as described above, it becomes difficult to apply the above-mentioned three-dimensional storage equipment as a wheel stopper for a railroad vehicle on a lift. For this reason, a driver is always required for loading and unloading railway vehicles, and loading / unloading cannot be automated.

That is, an object of the present invention is to provide a wheel stop device for a railway vehicle that solves such a problem, and also provide a three-dimensional storage facility for a rail vehicle using the wheel stop device.

[0008]

In order to solve the above problems, the present invention enables a car stop member to be arranged on a rail by rotational movement from the side of the rail, and its rotational movement surface relative to the rail. It is to incline.

That is, a wheel stop device for a railway vehicle that solves the above problems is for preventing the railway vehicle stopped on a rail from moving, and is a corner formed by the upper surface of the rail and the tread of the wheel. A wheel stopper arm having a wedge that fits in the end portion, and a wheel that is provided on the side of the rail and rotatably supports the wheel stopper arm, and the wedge of the wheel stopper arm fits in the corner. A hinge pin whose axis is inclined forward or downward to the front or side of the corner so as to move on a plane inclined forward or sideward of the corner between the stop position and the retracted position on the side of the rail. And drive means for rotating the wheel stopper arm.

In this case, "toward the front or side of the corner" as the direction of inclination of the hinge pin and the plane does not mean only one of the front and the side, but "in the middle". It is meant to include "diagonal front".

Further, the three-dimensional storage facility for a railway vehicle that solves the above-mentioned problems is provided with a storage cabinet having a multi-layer structure in which a storage section having a rail for the railway vehicle is provided on each floor, and a storage cabinet provided in front of the storage cabinet. And a vehicle elevating device for elevating the lift table on which the rails for the elevator are laid to the floors of the hangar so that the rails of the lift table are connected to the rails of the storage parts of the hangar. Two wheel stoppers according to claim 1 are provided for preventing front and rear movements of a railway vehicle on a table, respectively, with their hinge pins arranged at side portions of a rail of an elevator. It is characterized by

[0012]

In the wheel stopper device for a railway vehicle, the wedge of the wheel stopper arm has the upper surface of the rail because the axis of the hinge pin of the wheel stopper arm is inclined forward or downward to the front or side of the corner. And the treads of the wheels are fitted into the corner while descending diagonally from the upper front to the rear. That is, the wedge moves in the left-right direction of the rail, moves in the front-back direction, and moves in the vertical direction. Each of these movements then has the following effects.

The left-right movement allows the wedge to move between the wheel stop position on the rail and the retracted position on the side of the rail.

The movement in the front-rear direction allows the wheel stop position on the rail to be slightly shifted in the front-rear direction.

The movement in the vertical direction is combined with the movement in the front-rear direction, so that the wedge is surely brought into contact with both the upper surface of the rail and the stepping on the wheel, and a wedge effect effective for stopping the wheel is obtained.

To explain the above a little further, when the wedge is simply horizontally rotated, the above-mentioned actions and can be obtained, but the above-mentioned actions cannot be obtained. That is, in order for the wedge to be substantially in contact with the rail upper surface at the wheel stop position, it is necessary to make almost no difference in height between the rail upper surface and the wedge lower surface.
However, the rail normally sinks slightly under the wheel load of the railroad car, and it is also possible that it will sink due to other factors such as secular change. It is practically difficult to set the horizontal turning height of the wedge.

Therefore, in the case of the method of horizontally rotating the wedge as described above, it is necessary to make the height of the wedge considerably higher than the upper surface of the rail in order to surely prevent the interference with the rail. Therefore, the wedge cannot stop the movement of the wheel by the wedge effect, and needs to stop the wheel only by the power of the driving means of the wheel stop arm. This means that not only a large amount of power is required as the drive means, but also the drive by the drive means cannot be released even after the wedge is moved to the contact position with respect to the wheel.

As is clear from the above description, in the case of this means, even if an external force accidentally acts on the railway vehicle, the external force is received from the wheels by the wedge effect on the upper surface of the rail through the wedge. After the wedge is once moved to the wheel stop position, the drive of the wheel stop arm by the drive means can be released.

Further, in the above-mentioned three-dimensional storage facility for railway vehicles, the two wheel stoppers have their hinge pins for preventing forward movement and rear movement of the railway vehicle on the elevator, respectively. Since the railcars are arranged on the side of the rail, accidental forward movement and backward movement of the railcar mounted on the lifting platform can be reliably prevented during lifting.

[0020]

As described above, according to the wheel stopper device for a railway vehicle, the hinge pin of the wheel stopper arm having the wedge at the tip is forwardly or laterally forward of the corner formed by the rail upper surface and the wheel laterally of the rail. A plane that is inclined downward and is inclined forward or sideward of the corner between the wheel stop position where the wedge of the wheel stopper arm fits in the corner and the retracted position on the side of the rail. Since it moves above, the wedge can be moved to the wheel stop position even if the wheel stop position on the rail shifts back and forth, while ensuring that the wedge is both on the top surface of the rail and on the tread of the wheel. It is possible to obtain a wedge effect which is effective for stopping the wheel by contacting the wheel.

Further, according to the three-dimensional storage facility for a railway vehicle, the wheel stopper device is mounted on the elevator base of the vehicle elevator installed in front of the hangar having the multi-layered structure, and the rail vehicle is moved forward on the elevator base. Since it is provided for blocking and for preventing rear movement, it is possible to reliably prevent movement of the railcar on the elevator without braking the railcar, and between the elevator and the hangar. It is possible to automate the loading and unloading of railway vehicles by using the vehicle transport device to move the railway vehicles.

-Vehicle Carrier-In order to move the railway vehicle W between the respective storage sections 5 of the hangar 1 and the elevator 11 of the vehicle elevator 2, the elevator 11 is provided with a vehicle conveyor 21 shown in FIG. Is incorporated. That is, in FIG. 3, 22 is an endless roller chain wound around the sprockets 23 and 24 at both ends of the lifting table 11, 25 is a guide rail provided along the carrier side of the conveyor chain 22, and 26 is a guide rail 25. The vehicle carrier is supported by and is coupled to the roller chain 22.

More specifically, as shown in FIG.

The guide rails 25, 25 are fixed to the facing webs of the rail bases 11a, 11a, respectively. Both of the guide rails 25, 25 are formed to have a substantially U-shaped cross section, and the openings of the guide rails 25, 25 face inward.

The vehicle carrier 26 is the guide rail 2 described above.
Running body 28 supported by rollers 27 on 5, 25
And a connector 29 that is attachable to and detachable from the connector J of the railway vehicle W, and the connector 29 is supported by the traveling body 28 so as to be able to move up and down. The elevating means 31 is the traveling body 2
8 and a pinion 33 that is rotatably driven by a motor 32, and the pinion 3 that is fixed to a column of the coupler 29.
3 and the rack 34 in the vertical direction that meshes with each other.

Further, the connector 29 includes a first connecting portion 29a used when moving the railway vehicle W between the hangar 1 and the elevator 11, the second loading / unloading line 4, and the elevator 11. The second connecting portion 29 used when moving the railway vehicle W between
and b are provided in the front and rear, and are supported so as to be able to advance and retreat with respect to the above-mentioned column.

Wheel Stop Device FIGS. 5 and 6 show a wheel stop device 55 for preventing accidental movement of the railroad vehicle W on the rails 12 of the lift 11. That is, the wheel stopper device 5 that engages with the front wheel Wh of the biaxial wheels of the railroad vehicle W is mounted on the lift 11.
5 and a wheel stopper device 55 that engages with the rear wheel Wh are provided symmetrically. Note that FIG. 6 shows an example in which the left wheel Wh and the right wheel Wh are provided symmetrically as the wheel stopper device 55, but a pair of front and rear wheels Wh may be provided for each of the left and right wheels Wh. . Also, the second loading / unloading line 4
A similar wheel stopper device is also provided in each of the storage sections 5 of the storage case 1.

The structure of the wheel stopper device 55 will be described. This is a wheel stopper arm 57 rotatably supported by the rail base 11a, and a cylinder device (driving means) 58 for rotating the wheel stopper arm 57. And are equipped with.

That is, a bracket 59 is fixed to the upper portion of the side surface of the rail base 11a, and the center portion of the wheel stopper arm 57 is attached to the bracket 59 by the hinge pin 6.
Pivoted by 0. And the wheel stop arm 5
A tapered wedge 57a that fits into a substantially triangular corner formed by the stepping of the wheel Wh and the upper surface of the rail 12 is provided at the tip of the wheel 7. The hinge pin 60 has an axis of the rail 12
Along the front of the above-mentioned corner, it inclines forward and downward.

On the other hand, in the cylinder device 58, the base end of the cylinder portion is pivotally supported by a bracket 61 fixed to the lower portion of the side surface of the rail base 11a by a hinge pin 62 inclined like the hinge pin 60, and the tip of the piston rod. Is the same hinge pin 6 at the base end of the arm 57.
They are connected by 3.

Therefore, the wheel stopper arm 57 is rotated so that the wedge 57a moves on the plane inclined forward and upward toward the front of the corner as the piston rod advances and retracts. With the advance of
The wedge 57a is in a wheel stop position where it is fitted in the corner formed by the wheel Wh and the rail 12, and the wedge 57a is in a retracted position diagonally above and laterally of the rail 12 due to the retraction of the piston rod. Then, the front and rear wheel stopper arms 57, 57 come into contact with the front and rear wheels Wh, Wh from the front and rear, so that the railway vehicle W cannot move forward and backward.

When the wedge 57a is moved to the wheel stop position, the wedge 57a is moved laterally on the rail from the side of the rail, and at the same time, moved backward and descends. Because of this rearward movement, even if the stop position of the wheel Wh deviates back and forth from the planned position, the wedge 57a can move to a position where it fits into the corner portion, and because of the lowering. The upper surface of the wedge 57a contacts the wheel Wh harder and the lower surface of the wedge 57a reliably contacts the upper surface of the rail. In this case, the wedge 57a is connected to the wheel stopper arm 5 by
Since there is some vertical play due to the hinge pin 60 of No. 7, the contact between the wheel Wh and the upper surface of the rail are reliably contacted.

-Regarding the mode of loading / unloading- (Incoming from the first loading / unloading line 3) The railway vehicle W runs on the first loading / unloading line 3 and enters the loading unit 5 on the first floor of the hangar 1 (Fig. 7). The two wheel stoppers 55 of the storage unit 5 are operated (the wedge 57a moves to the wheel stopper position) to hold the wheels Wh of the railroad vehicle W from the front and the rear. The driver of the railway vehicle W releases the brakes of the railway vehicle W and gets off here. The lift table 11 stops at a position corresponding to the storage section 5 (the lift table 11 may be stopped at this position in advance).

The vehicle carrier 21 operates, and the vehicle carrier 26 moves to the end of the lift 11 on the side of the storage section 5 (note that the previous operation of the vehicle carrier 21 causes the railcar W to move). This is necessary when the sheet is sent to the second loading / unloading line 4, and if the previous operation is for other than that, the movement is not necessary).

The connector 29 of the vehicle carrier 26 rises, and the first connector 29a of the connector 29 projects toward the storage part 5 and is joined to the connector J of the railroad vehicle W (state of FIG. 7). Since the wheel stopper device 55 holds the wheels Wh of the railcar W from the front and rear, the railcar W at the time of the connection is
There is no accidental transfer of. After that, the wheel stop device 5
5 moves the wedge 57a to the retracted position to release the holding of the wheels Wh.

As the vehicle carrier 26 travels to the end of the elevator 11 on the side of the second loading / unloading line 4, the railway vehicle W moves from the storage section 5 to the elevator 11 (state in FIG. 8). Even after this transition, the connected state of the transporting vehicle 26 and the railway vehicle W is maintained.

The wheel stopper device 55 on the lift 11 operates to hold the wheels Wh of the railway vehicle W from the front and the rear. This prevents accidental movement of the railroad vehicle W while the elevator platform 11 is being raised or lowered.

The lifting platform 11 rises to the floor where the railway vehicle W is to be stored (see FIG. 9). If the planned storage floor is underground, it will descend.

After the wheel stopper device 55 on the lift 11 moves the wedge 57 a to the retracted position, the vehicle carrier 26 travels to the end portion on the storage section 5 side, and the railway vehicle W is stored in the storage section 5. Put in.

The wheel stopper device 55 of the storage unit 5 operates to hold the wheels Wh of the railway vehicle W from the front and the rear.
This prevents accidental movement of the railway vehicle W during storage. Further, the connector 29 of the vehicle carrier 26 operates to release the connection between the first connecting portion 29a and the railway vehicle W, the first connecting portion 29a retracts, and the connector 2
9 descends.

(Incoming from the second loading / unloading line 4) Railway vehicle W
While self-propelled along the second loading / unloading line 4 and stopping at the end of the loading / unloading line 4, the lifting platform 11 stops at a height above the ground (a position corresponding to the storage part 5 on the first floor above the ground). After that, the railway vehicle W is stored in the same flow as in the case of storing from the first loading / unloading line 3. The differences are as follows.

A. The point that the vehicle carrier 26 and the railway vehicle W are connected using the second connecting portion 29b of the connector 29.

B. The vehicle carrier 26 moves from the end on the second loading / unloading line 4 side of the elevator 11 to the end on the hangar 1 side to move the railway vehicle W from the second loading / unloading line 4 onto the elevator 11. After that, for the purpose of warehousing into the planned storage section 5, it is necessary to temporarily disconnect the connection with the railroad vehicle W and run idle from the hangar 1 side to the second storage line 4 side.

(Outgoing to the first loading / unloading line 3) In this case,
Since the operation of warehousing from the first warehousing / leaving line 3 described above is the reverse operation, a lot of explanations will not be required. That is,
At the time of the previous warehousing, the railway vehicle W was moved from the storage unit 5 on the first floor to the storage unit 5 on the other floor, but in the case of the warehousing,
The railway vehicle W is moved from the storage unit 5 on the other floor to the storage unit 5 on the first floor above the ground, and there is no substantial difference in the operation mode. The driver boarded the railway vehicle W transferred to the storage unit 5 on the first floor above the ground, and the railway vehicle W self-propelled,
The vehicle will depart from the storage unit 5.

(Outgoing to the second shipping line 4) Also in this case,
Since the operation mode is the reverse of the warehousing from the second warehousing / leaving line 4 described above, the description thereof will be omitted.

It goes without saying that the wheel stopper device can be applied not only to the three-dimensional storage equipment for railway vehicles, but also to the storage equipment (the yard) in which a large number of lateral lines are branched in a plane.
