Description

[Detailed description of the invention] The present invention relates to a railway crane.

As shown in Figure i1, a conventional railway crane is equipped with a revolving body 1 on a traveling body 3 so as to be able to rotate horizontally, and as a means for hoisting a load onto this revolving body 1, there is a pool 2 that can be raised and lowered and supported by a rope from the pool 2. As shown in FIG. has been done. Since this platform $4 is mounted on the railway, the traveling body 3 is freely supported by the trolley 4. In the case of such a conventional example, the length is Easily subject to load restrictions. This restriction had the disadvantage that railway cranes could not be dispatched to their destinations because they could not cross the bridge.

The purpose of the present invention is to expand the range of activity of a railway crane and at the same time to ensure sufficient stability in lifting work.

The gist of the present invention is that, as a basic configuration, there is provided a railway crane equipped with a means for hoisting a load onto a traveling body supported by a bogie running on a railway. A bogie is provided, a swinging pillow having a long groove in the vehicle width direction is attached to the bogie in the center portion, and the traveling body is mounted on the swinging pillar via a guide roller directed in the vehicle width direction, which is a guiding direction. A traveling support device for a railway crane, characterized in that a pin attached to the traveling body is passed through the groove, a receiver is attached to the pin, and the shape of the receiver is such that it hits the swinging pillow in the vertical direction. The front and rear ends and the center of the running body are supported by bogies to reduce the weight distribution per length of the railway, and the running body is free by the length of the groove with respect to the central bogie. The crane can safely pass through a curved road with a small radius, and when lifting a load, it can improve the stability of the railway crane by receiving the dead weight of the intermediate truck on the traveling body side.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 7.

A pool 2 in which a hanging tool 2a is suspended and supported by a rope is attached to a revolving body 1 so as to be able to rise and fall freely. The revolving body 1 is attached to the traveling body 3 so that it can freely rotate horizontally.

The traveling body 3 is made longer in the forward and backward directions than the traveling body of a conventional railway crane.

The traveling body 3 is provided with three carts 5 and 6 at approximately equal intervals.

The trolley 5 is arranged at the forward and backward movement end side of the traveling body 3, and is attached to the traveling body 3 so as to be horizontally rotatable.

The intermediate truck 6 has an axle 13 as shown in FIGS. 4 and 5.
The vehicle is equipped with a truck frame 10 that supports the vehicle.

A swing pillow 11 that is long in the vehicle width direction of the truck 6 is attached to the truck frame 10 via a coil spring 14 so as to be vertically movable.

The rocking pillow 11 is provided with a shaft 9 in the center that is long in the vehicle width direction, and this shaft 9 has a shape that opens upwardly and downwardly.

A center pinot 17 is passed through the groove 9. The upper end of the center pin 17 is fixed within a bottle receiver δ to which the traveling body 31 is fixed. A guide rod 18 having a square appearance is rotatably attached to the center/middle part of the bottle 17 via a post 19. Spring holder 2 at the bottom of center bottle] 7
1 is fixed, and the upward coil supported by this spring holder 21 is supported by a spring n, and the holder is fit into the lower part of the center pinot 17 so as to be able to move up and down. Ukehataha,
It has a cylindrical shape as a whole, and has a flange portion 23a whose lower end protrudes horizontally to such an extent that it cannot fit into the groove 9.

A bearing 15 is fixed to the upper surface of the rocking pillow 11, and a guide roller 16 is rotatably supported by the bearing 15. The guide direction of this guide roller 16 is directed in the vehicle width direction. The upper part of the guide roller 16 is as shown in FIG.
A reverse gate-shaped guide plate (24) is mounted so as to cover it. This guide plate 24 is fixed to the traveling body 3.

As shown in FIG. 7, the sliding plates are fixed to two sides of the guide block 18, and the two sliding plates are in contact with the inner surface of the groove 9.

Both carts 5 and 6 are mounted on the railway, so that the railway crane can run on the railway.

According to such an embodiment, the distance between each carriage *5, 6 is wide, and the arrangement of each carriage 5, 6 is even, so that the weight of the railway crane applied to the railway is distributed evenly over a long length. dispersed between Therefore, it is possible to safely pass through bridges that have a limit on the load per unit length.

Furthermore, when traveling on a curved railway road with a small radius R as shown in FIG. Therefore, it is necessary for the traveling body 3 to shift by eight dimensions in the vehicle width direction with respect to the intermediate truck 6. This necessity is achieved by the traveling body 3 moving in the vehicle width direction on the guide rollers 16 at the same time as the guide gray) 24. During this movement, the sliding plates in the groove 9 slide on the inner surface of the beam 9, and the middle IL/pinot 17 moves in the same direction as the movement of the traveling body 3 in the axle direction. Therefore, the traveling body 3 is allowed to shift by eight dimensions relative to the truck 6 in the vehicle width direction.

Even if the traveling body 3 deviates in the vehicle width direction in this way, the center bin 17 is caught in the groove 9 by the rocking pillow 11 in the forward and backward directions via the guide block 18 and the sliding plate. In this way, the traveling traction force is transmitted between the truck 6 and the traveling body 3.

Therefore, even curved railway roads can be passed smoothly.

In this way, when a railway crane is being towed to its destination by an intermediate car, it can pass smoothly and safely even if there are weak bridges or curved railway roads with a small radius on the way. .

In addition, when the railway crane that has stopped at its destination starts crane work, at the second time, an outrigger (not shown) is pushed out and a part of the weight from the traveling body 3 is transferred to the ground via the outrigger. It will be supported. In this case, the traveling body 3 becomes slightly more floating than when traveling, but
At this time, the collar portion 23a of the receiver n is caught on the rocking pillow 11, and the weight of the stand $6 is applied to the traveling body 3 side. In this case, the weight of the truck 6 is added to the traveling body 3, and the weight of the truck 6 acts on the traveling body as a weight to stabilize the unstable balance of the railway crane during lifting work. Therefore, lifting work of the load can be accomplished in a stable state.

Furthermore, the impact when the rocking pillow 11 is hooked on the collar portion 23a is alleviated by the coil spring ρ, making it safe.

Also, since the swinging pillow 11 is hooked up to the traveling body 3 side,
The rollers 16 do not come off from the reverse concave shape of the example guide plate, and preparation for re-travel is easy.

In particular, the structure in which the truck 6 is connected to the two truck frames lO and each truck frame 10 via the axle 13 is extremely cylindrical because there is no need to firmly connect and fix the truck frames 10 with other strength members. It has a trolley configuration. However, since the strength is weak, the four sides formed by each truck frame lO and the axle 13 are deformed, and the swing pillow 11 is slightly twisted. This tension is applied to the roller 16 by the amount of clearance C between the end face of the roller 16 and the end face of the kite plate 24.
The kite block 18 is allowed to slide between the and the kite plate, and the kite block 18 is allowed to rotate around the center pin 17 via the boss 19. Therefore, no unreasonable action will occur anywhere due to this twist. In this way, an extremely simple truck 6 as shown in FIG. 4 could be adopted since unreasonable effects were avoided.

As described above, according to the present invention, by employing the intermediate bogie, the dead weight of the railway crane can be distributed over a wide range and applied to the railway road side, and at the same time, it is possible to tolerate the vehicle width deviation between the traveling body and the intermediate bogie. Since the intermediate bogie can be used as a weight to improve stability, the range of operation of the railway crane can be expanded by passing through weak areas and curved railway roads with a small radius, and the work of lifting loads can be done in a stable state. Implementable effects can be obtained.
