BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railway vehicle carrier used to push and move a railway vehicle on a main rail, and more specifically, to operate a pusher mechanism that engages with a wheel of the railway vehicle when pushing the wheel. It concerns the structure of the part.

[0002]

2. Description of the Related Art Conventionally, as this type of railway vehicle carrier, for example, there is one disclosed in Japanese Patent Laid-Open No. 62-160957. This is movable along a main rail and a guide rail laid along the main rail to a wheel catching machine a as shown in FIG. 9, and is attached to the tip of a pusher arm b attached to the wheel catching machine a so as to be able to move up and down. A pusher roller c capable of engaging with a wheel on the main rail is provided, and a wire rope d for moving the wheel catcher a is connected to both ends of the wheel catcher a. Then, by applying a strong tension to the wire rope d, the rod f in the vehicle catcher a is pulled against the spring e, and the pushing of the pusher arm b by the tip of the rod f is released. The pusher arm b is erected by the force of h via the rod i, and the pusher roller c at the tip of the pusher arm b is moved to the engagement position with the wheel. By weakening, the force of the spring e overcomes the force of the spring h, and the pusher arm b is tilted by the rod f to move the pusher roller c to the retracted position.

[0003]

In such a conventional example, since the pusher arm b can be erected and the pusher roller c can be engaged with the wheel by applying tension to the wire rope d, it can be remotely operated. It can be operated, and even if the stop position of the vehicle is not constant, the vehicle catcher a can be moved to that position and the pusher arm b can be erected at an arbitrary position. However, in such a conventional example, the spring h urges the pusher arm b upright via the rod f, and normally the strong spring e is used.
Since the pusher arm b is pushed down by pushing the rod f with the force of, the spring h is always compressed by the force of the spring e except when the pusher arm b is erected. There is a problem that it easily deteriorates and its life is shortened. Further, in order to raise or tilt the pusher arm b, the structure in which the rod i is connected to the pusher arm b and the tip of the rod f is pressed and the force of the two rods f and i acts on the pusher arm b must be adopted. However, there is a problem in that the structure for raising and lowering the pusher arm b becomes complicated and precision is required for each part and assembly in order to operate the pusher arm b accurately.

The present invention has been made in view of the above problems, and an object of the present invention is to raise and lower the pusher arm by the strength of the tension applied to the wire rope when moving the railway vehicle and pusher roller. Can be engaged or retracted, and the parts such as the pusher arm can be prevented from being damaged even if the pusher roller is erected upright with the wheels present, and the structure of the device can be simplified. An object is to provide a transportation device for a vehicle.

[0005]

In order to achieve the above-mentioned object, a railway vehicle carrier according to the present invention comprises a wheel catcher 3 along a main rail 1 and a guide rail 2 laid along the main rail 1.
A wire rope for moving the wheel catcher 3 is provided with a pusher roller 5 that can be engaged with the wheel 6 on the main rail 1 at the tip of a pusher arm 4 that is attached to the wheel catcher 3 so as to be able to move up and down. 10 is connected to both ends of the wheel catcher 3, and a strong tension is applied to the wire rope 10 to erect the pusher arm 4 to move the pusher roller 5 at the tip of the pusher arm 4 to the engagement position with the wheel 6. In the one in which the pusher arm 4 is tilted to move the pusher roller 5 to the retracted position by weakening the tension of the wire rope 10, the first rod 20 and the second rod 27 are positioned so that the second rod 27 is located on the pusher arm 4 side. As shown in FIG.
The wheel catcher 3 is provided with a first spring 23 that connects the end of the wire rope 10 to one end of the first rod 20 opposite to the pusher arm 4 side and biases the first rod 20 toward the pusher arm 4 side. The other end of the one rod 20 and the second rod 27
Is connected to the pusher arm 4 at the other end of the second rod 27 via the second spring 26, and the spring force of the second spring 26 is set to be weaker than the spring force of the first spring 23. It is characterized by

Further, side guide rollers 13 are rotatably mounted on both sides of the wheel catcher 3, and the side guide rollers 13 are rotatably provided in the recesses 14 on the side portions of the main rail 1 and the guide rail 2. The upper guide rollers 15 are rotatably mounted on both sides of the upper portion of the wheel catcher 3, and the upper guide rollers 15 are rotatably provided along the upper side surfaces of the main rail 1 and the guide rail 2. Is also preferable.

[0007]

When the wheel catcher 3 is moved by the wire rope 10 to stop the wheel catcher 3 at a position corresponding to the appropriate wheel 6, and the wire rope 10 is applied with a tension higher than a certain level stronger than the first spring 23. , The first rod 20 is pulled in the opposite direction to the pusher arm 4 against the first spring 23, and the pusher arm 4 is pulled via the first rod 20, the second spring 26, and the second rod 27. Stands up and the pusher roller 5 engages with the wheel 6. When the tension of the wire rope 10 is weakened to a certain value or less, the force of the first spring 23 causes the first rod 20 to return,
The pusher arm 4 falls and the pusher roller 5 returns to the retracted position. Further, even if the first rod 20 is pulled when the pusher arm 5 is tensioned to the wire rope 10 in a state where the pusher arm 5 is located immediately below the wheel 6 by an erroneous operation and the first rod 20 is pulled, the second spring 26 Does not force the second rod 27 to be pulled and the pusher arm 5 is not forced.

[0008]

EXAMPLE A guide rail 2 is laid parallel to the main rail 1 on the outside of one of the main rails 1 of the pair of main rails 1, and a wheel catcher is provided between the main rail 1 and the guide rail 2. 3 is movably attached. As shown in FIG. 8, a wire rope 10 is arranged outside the guide rail 2 and between the guide rail 2 and the main rail 1, and the wire rope 10 is annularly arranged around the guide rail 2. I am running around. The wire rope 10 can be annularly driven by a winch 11, and by driving the wire rope 10, the wheel catcher 3 connected to the wire rope 10 is moved. The wire rope 10 is wound around the tension roller 12 at the end of the guide rail 2 in the longitudinal direction, and the tension roller 12 can freely apply tension to the wire rope 10.

It rolls along 4 freely. A plurality of upper guide rollers 15 are rotatably mounted on both sides of the upper portion of the wheel catcher half 3a, and the upper guide rollers 15 are rotatably mounted on the upper side surfaces of the main rail 1 and the guide rail 2. I have it. Then, by driving the wire rope 10, the side guide roller 13 and the upper guide roller 15 roll along the main rail 1 and the guide rail 2 so that the wheel catcher 3 moves smoothly. Further, a wire rope guide roller 17 is arranged outside the guide rail 2,
Wire rope 10 is wire rope guide roller 17
It is designed to be moved by being guided by.

As shown in FIGS. 2 and 5, each wheel catcher half 3a of the wheel catcher 3 has a pivot shaft 7 so as to project to the main rail 1 side at the side where the wheel catcher half 3a is connected. Is projected. The pivot shaft 7 is provided so as to project in a direction orthogonal to the longitudinal direction of the main rail 1, and is also provided so as to be inclined so as to be lowered downward toward the main rail 1 side. Pivot 7
The base of the pusher arm 4 is mounted so that the pusher arm 4 rotates about a pivot shaft 7, and a nut 18 screwed onto the tip of the pivot shaft 7 prevents the pusher arm 4 from coming off.
The pusher arm 4 rotates in a plane orthogonal to the pivot shaft 7. A pusher roller 5 is rotatably attached to the tip of the pusher arm 4. Then, when the pusher arm 4 is rotated so as to be raised, the pusher roller 5 moves toward the main rail 1 side due to the inclination of the pivot shaft 7, and when the pusher arm 4 abuts on the stopper 19, the pusher roller 5 is raised. Is located on the main rail 1 and is located at a position where the pusher roller 5 engages with the wheel 6.
When the pusher arm 4 is tilted downward, the pusher roller 5 moves away from the main rail 1 due to the inclination of the pivot shaft 7, and the pusher arm 4 and pusher roller 5 are moved to the main line while the pusher arm 4 is tilted substantially horizontally. It is housed between the rail 1 and the guide rail 2, and the pusher roller 5 retreats from the position of engagement with the wheel 6.

A first rod 20 is longitudinally slidably mounted on each wheel catcher half 3a of the wheel catcher 3, and a wire rope is connected to one end of the first rod 20 in the longitudinal direction. A portion 21 is provided, and the end portion of the wire rope 10 is connected to the wire rope connecting portion 21.
A spring accommodating portion 22 is provided so as to surround the first rod 20 in the wheel catcher half 3a, and a first spring 23 made of a compression spring is accommodated in the spring accommodating portion 22. The end portion of the first spring 23 is engaged with the collar portion 24 of the first rod 20, and the first spring 23 urges the first rod 20 toward the pusher arm 4 side. A spring accommodating portion 25 is provided at the end of the first rod 20 on the pusher arm 4 side, and the spring accommodating portion 25 includes a second spring 26 that is a compression spring.
Is decorated. The second rod 27 is slidably mounted on the wheel catcher half 3a between the first rod 20 and the pusher arm 4, and a part of the second rod 27 is inserted into the spring housing portion 25. . The collar portion 28 of the second rod 27 is the second
It is engaged with one end of the spring 26 and urges the second rod 27 in the direction opposite to the pusher arm 4. A connecting rod 29 is arranged between the second rod 27 and the pusher arm 4, and one end of the connecting rod 29 is connected to the second rod 27.
Is rotatably connected to the other end of the connecting rod 29, and the other end of the connecting rod 29 is rotatably connected to the pusher arm 4 above the pivot shaft 7. Regarding the first spring 23 and the second spring 26, the spring force of the first spring 23 is sufficiently stronger than that of the second spring 26. However, if the tension applied to the wire rope 10 is less than a certain value, the spring force of the first spring 23 is so strong that the first rod 20 does not slide and the second rod 27 does not move as shown in FIG. 6A. The pusher arm 4 does not slide and remains tilted. In this state, if the wire rope 10 is applied with a tension of a certain value or more (stronger than the spring force of the first spring 23), the first spring 23 becomes as shown in FIG. 6B.
The first rod 20 is pulled by the wire rope 10 and slides against the load, and the sliding of the first rod 20 causes the second rod 2 to move.

[Effect of the Invention] The present invention, as described above, includes the first rod and the second rod.
The rod and the second rod are arranged in a line so that the second rod is located on the pusher arm side, and are mounted slidably in the wheel catcher in the longitudinal direction. The end of the wire rope is attached to one end of the first rod opposite to the pusher arm side. The wheel catcher is provided with a first spring for urging the first rod toward the pusher arm, and the other end of the first rod and one end of the second rod are connected via the second spring and The other end of the rod is connected to the pusher arm, and the spring force of the second spring is set to be weaker than the spring force of the first spring. The first rod is pulled in the opposite direction of the pusher arm against the spring, the pusher arm is pulled via the first rod, the second spring, and the second rod, and the pusher arm stands up and pusher roller When the wheel is engaged and the tension of the wire rope is weakened to a certain value or less, the first rod returns by the force of the first spring, the pusher arm falls down, and the pusher roller returns to the retracted position. Depending on the tension applied to the rope, the pusher arm can be raised and lowered to move the pusher roller to the engaging position or the retracted position. Even if the first rod is pulled when the operation of raising the pusher arm with tension is applied, the second spring does not stretch and the second rod is not pulled forcefully, and the pusher arm is not forced. It is possible to reliably prevent the arm, pusher roller, etc. from being damaged. Since the rod and the second rod are arranged in a straight line and are urged in the same direction by the first spring and the second spring, the first spring and the second spring are Since the forces that interfere with each other in the stretched state do not act, there is no factor that deteriorates the spring as in the conventional case, and the life can be improved. Furthermore, the pusher arm has a structure in which only the second rod is connected. Since the structure that allows the pusher arm to be tilted can be simplified, the structure for tilting the pusher arm is simpler than before, and the precision of the parts and assembly is not required as much as in the past to operate the pusher arm accurately. It is a thing.

According to a second aspect of the present invention, side guide rollers are rotatably mounted on both sides of the wheel catcher, and the side guide rollers are recessed in the main rail and side portions of the guide rail. Since the upper guide rollers are rotatably mounted on both sides of the upper part of the wheel catcher and the upper guide rollers are rotatably mounted on the main rail and the upper side surface of the guide rail, Even if the wheel catcher travels between the rail and the guide rail, the wheel catcher travels smoothly by being guided by the side guide rollers and the upper guide rollers. It is possible to move the pusher arm up and down due to the strong and weak tension on the wire rope, and it is possible to move the Deployment is intended never to malfunction at stake.
