Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a jacking car for derailment restoration, which is suitable for use when restoring a derailed bogie.

[Conventional technology]

The trolleys called iron trolleys that are pulled by motor cars and used to transport rails, sleepers, etc. are built with a lower height than other general vehicles, so ready-made jacks are used to transport rails, sleepers, etc. It is very difficult to put it under and restore it, and even if you try to lift it by hand and restore it,
A normal trolley weighs more than 2 kg, and since the weight of the loaded rails and other objects is added to it, it was completely impossible to restore the area manually.

Therefore, the idea was to develop a jack specifically for low-height bogies and use this jack to push the bogie up to recover from the derailment, but this jack only pushes the bogie up and cannot move it laterally. During recovery, it is necessary to repeatedly push up the trolley with jacks and move it laterally, which is very dangerous and time consuming.Furthermore, if the wheels are damaged due to derailment, There is a problem in which the trolley cannot be moved even if it is restored using jacks, so in the end, a crane truck is called in to lift the truck and the truck is restored, or if the wheels are damaged, a crane truck is used to lift the truck and move it. was.

[Problem to be solved by the invention]

However, when hoisting a trolley with a crane truck, it is necessary to unload the loaded rails, sleepers, etc., so this work takes time and can take time to restore.
In addition, if there is no crane nearby, it takes time to call for one, so recovery using a crane is very troublesome, and if a bogie derails on a commercial line, it can significantly delay the schedule. Furthermore, if a train derails on a track that cannot be accessed by a crane, there is the problem that the crane cannot be used to restore the track, and it takes time to recover.

Therefore, the technical problem of the present invention is to be able to recover the derailment of a bogie extremely easily, safely and in a short time no matter where the derailment occurs, and furthermore, to recover the derailment of a bogie in a short time. To provide a jacking car for derailment recovery that is devised so that the bogie can be moved smoothly even in such cases.

[Means to solve the problem]

The measures taken in the present invention to solve the above technical problems are as follows.

(1) A plurality of wheel bodies configured to be able to move freely on the rails, which can be freely placed on the wheel bodies, and a moving block that can be moved laterally with respect to the rails is installed inside, and these wheels are installed at both ends. A main frame body to which a lever block for moving the movable block is attached, a cylinder unit configured to be freely placed on the movable block, and a cylinder unit that can be freely connected to an arm mounting bracket attached to the side of the derailed truck, and
and a return arm capable of raising a derailed bogie to a predetermined height by being pushed up by the rod of the cylinder unit.

(2) Furthermore, an arm holder that can be freely mounted on the main frame body and has a universal joint on the top surface, and one end can be freely connected to an arm mounting bracket that is attached to the trolley, and and a traveling arm, the other end of which is connected to the universal joint of the arm pedestal, and is capable of supporting the truck in an elevated state by the returning arm.

[Effect]

The above means works as follows.

■The element (1) above is that when recovering from a derailment, first place the wheel body on the rail, place the main frame body on top of this wheel body, and then place it on the moving block installed on the main frame body. Install the cylinder unit.

By operating the lever block and moving the moving block, this cylinder unit is aligned with the return line arm connected to the arm mounting bracket of the derailed bogie, and the rod is protruded by remotely controlling the cylinder unit. For example, this rod pushes up the return arm to raise the bogie, then operate the lever block mentioned above to move the moving block, align the wheels of the bogie with the rail, and then remotely control the cylinder unit again. By lowering the rod, the derailed truck can be quickly and safely restored.

■The element (2) above is that after the rod of the cylinder unit raises the truck, the traveling arm attached to the arm mounting bracket of the truck is connected to the universal joint of the arm holder attached to the main frame. For example, even if the rod of the cylinder unit is lowered, the traveling arm supports the bogie in the raised state, so even if the wheels of the bogie are damaged due to derailment, the wheels of the main frame body will remain in the raised state. Allows the body to move quickly.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.

Since the derailment recovery jack vehicle according to the present invention is as described above, when the bogie 30 is derailed, the two wheel bodies 13 and 14 are placed on the front rails Xa and Xb, and then, The main frame body 1 is set on these wheel bodies 13.14 using the handles 15.16, the case body 20 carrying the cylinder unit 21 is attached to the moving block 3, and the arm of the derailed bogie 30 is attached. Attach the return line arm 22 to the return line bracket 31 or 32 using the pin 23, then fit the support shaft 22a of the return line arm 22 into the support groove 21a of the rod 21R, and then supply hydraulic pressure to the cylinder unit 21. When the rod 21R is projected upward, the derailed truck 30 is lifted up by the returning arm 22 as shown in FIG. 4.

After lifting the truck 30 as described above, move the moving block 3 by operating the lever blocks 10 and 11, and move the axle 3
After aligning 0T and 30T to each rail Xa and Xb,
If the hydraulic pressure is removed from the cylinder unit 21 and the rod 21R is lowered, the bogie 30 can be returned to the rails Xa and Xb.
The double track work is completed by removing the cylinder unit 21 and the main frame body 1, and removing the axle bodies 13 and 14.

On the other hand, if the wheels 30T are damaged due to derailment and the bogie 30 cannot run, the return arm 22
0 is lifted up, that is, in the state shown in FIG. If the traveling arm 27 is connected between them using pins 26 and 28, 28, respectively, as shown in FIG. The lifted state is maintained by the arm 27, and the jacking vehicle of the present invention itself serves as a bogie to enable the carriage 30 to be transported.

〔effect〕

As described above, according to the jacking vehicle for derailment recovery according to the present invention, even in the case of a bogie that is too low to be lifted with a ready-made jack, it can be lifted, and
It is possible to return to the track in an extremely short time by moving it laterally, and furthermore, even if it is unable to run due to wheel damage caused by derailment, the jacking vehicle of the present invention can be used as a bogie and can be run freely. It is possible to get back on track and run safely in a much shorter time than when using a car, and it is also possible to get back on track easily even in places where crane trucks cannot enter. In addition to the fact that it can usually be disassembled and stored in a compact manner, it is extremely convenient for transportation and storage.
