Description

[Detailed description of the invention] Industrial application field: The present invention relates to an improvement of a derailment recovery device for a railway vehicle.

BACKGROUND OF THE INVENTION Conventionally, various ideas have been disclosed and put into practical use for restoring a derailed railway vehicle to its original track. For example, prior art is disclosed in Publication Utility Model No. 41-18242, Publication Utility Model No. 7125-42, Publication No. 4732-44-54, and the like.

Regarding the device of this prior invention, the former (Jikko Sho 41
In the system disclosed in Publication No. 18242), two wheeled supports that are raised by alternately operating two jacks are placed at required intervals on the return rail that intersects on the main track. Then, the vehicle is lifted up via the cross beam for supporting the vehicle, and the vehicle is tried to return to the track from the derailed position, which requires many operations and requires many components. In the latter, disclosed in Japanese Utility Model Publication No. 42-7125, a long and slender bogie is placed on the return rail, and jacks are placed on both ends of the bogie to lift the derailed vehicle and move it along the return rail. Since the pinion attached to the bogie that meshes with the installed rack gear is manually rotated to move it along the return rail, it is convenient that a pair of jacks attached to one bogie can not respond to derailed vehicles. Since it cannot be achieved, it may be inconvenient to operate.

Furthermore, the return track device shown in Japanese Utility Model Publication No. 54-4732 is a device that has improved the above-mentioned problems, but it also has a serrated transverse feed rack along the curved return track rail. The locking means for engaging the locking pawl with this cross-feeding rack and the return track truck with jacks are connected by a hydraulic cylinder, and the truck is moved by the hydraulic cylinder. The stop means must be repositioned every time the moving hydraulic cylinder moves one stroke, which is time-consuming, and the return rail also uses a transverse feed rack attached at an irregular position. Therefore, it was often inconvenient to assemble the long rails in an orderly manner at the accident site under poor conditions.

Problem to be solved: In this conventional recovery system for derailed vehicles, a jacked truck for returning to the track is placed below the derailed vehicle, and the vehicle is returned to the main track along the returning rail. When performing lateral movement for the purpose of horizontal movement, the operator had to perform the lateral movement operation directly or change the movement reaction force position intermittently.
The device of this invention is capable of horizontally moving from the derailed position to the main track using remote control after preparations for recovery have been made, and is intended to be a device that can rationally recover by further improving work efficiency. .

Measures to solve the problem: A curved rail that can be placed across the track, two cross-feeding carts equipped with jacks that can move on the curved rails, and the cross-feeding carts are interconnected. In a derailed vehicle recovery device, which has a continuous link that moves, and a reaction force holding device on the curved rail side during movement; the moving reaction force holding device straddles the curved rail along the curved rail, and A clamp frame with guide rollers in contact with the front and rear and both outside sides of each rail, a pair of left and right clamp claws whose bases are pivoted in a direction perpendicular to the curved rail inside the clamp frame, and both clamp claws. This clamp frame is constructed of a locking cylinder that is mounted between the clamping cylinders and locking the clamping claws, and the clamp frame is configured to clamp the curved rail using the guide rollers disposed on the outside and the clamping claws. This is a derailment recovery device characterized by connecting a cross-feeding bogie with a cross-feeding cylinder.

Effect: With this configuration, when a derailed vehicle is returned to the main track, a curved rail is assembled by well-known means, and two sets of cross-feeding bogies are connected to each other on this curved rail and placed. At the same time, the clamp frame of the reaction force holding device is connected to one of the carts and preparations are made.

The jacks on the cross-feeding truck are lifted and floated with respect to the derailed vehicle, and then the locking cylinder built into the clamp frame of the reaction force holding device is activated by sending pressure medium in the direction of extension. Then, the locking cylinder causes the clamp claw to come into contact with the inside of the curved rail, and the outside roller clamps the curved rail, thereby fixing the clamp frame. After that, if pressure medium is supplied to the cross-feeding cylinder and the piston rod of the cross-feeding cylinder is extended, the connected cross-feeding bogie will move along the curved rail toward the main track side, and the lifted and supported vehicle will be placed on the rail. Bring it closer. 1 of this horizontal feed cylinder
When the movement for the stroke is completed, the locking cylinder is actuated in the retracting direction to release the fixation from the curved rail, and the piston rod of the cross-feeding cylinder is moved backward, thereby moving the clamp frame by one stroke. Then, the locking cylinder is operated again to fix the clamp frame to the curved rail, and the cross-feeding cylinder is again operated to extend, thereby moving the vehicle being lifted via the cross-feeding truck.

By repeating such operations, the traverse carriage and the clamp frame are moved alternately in order to return the derailed vehicle to the main track.

Embodiments: The device of the present invention will be described in detail with reference to embodiment figures as follows.

1 and 2 are a plan view and a front view of the device of the present invention arranged on the main track,
1 is a curved rail for cross-feeding, which can be divided into three parts for easy transportation and on-site assembly. Reference numerals 2 and 2' are transverse carriages, each of which can run along a curved rail 1 with four wheels 3, and has a hydraulic jack 4 erected on its upper center surface. 5 is both side feed carts 2, 2'
It is a link that connects.

Reference numeral 10 denotes a reaction force holding device, which includes a clamp frame 11 that is movable across the curved outer rail and inner rail of the curved rail 1, and a locking cylinder that operates a clamp claw built into the clamp frame 11. One side of this clamp frame 11 and the rear side (or front side) of one of the traverse carriages 2 are connected by a traverse cylinder 6.

As shown in FIGS. 3 to 6, the clamp frame 11 has a rectangular box shape with an open bottom surface, and mounting seat pieces 12 for outer guide/receiving rollers 13, 13 are fixed horizontally at both longitudinal ends thereof. , rollers 14 for supporting and running along the curved rail are installed at both ends of the longitudinal side plates 11', 11'.
5 are attached to the front and rear, respectively. Inside this frame 11, a pin 1 is supported at both ends in parallel to the running direction, passing through side plates 11', 11'.
Clamp claws 17, 17 are loosely provided at the proximal ends of the clamp claws 17, 16, respectively.
A locking cylinder 18 is installed between the floating parts 7 and 17,
Its base end and piston rod 18' tip connecting piece 1
8'' and are connected with pins 19 and 19', respectively, and are installed horizontally.
7' are each shaped so as to hold the head of the curved rail 1 when clamped (of course, this is not limiting). The center line of action of the locking cylinder 18 is aligned with the center of the peripheral surface of the receiving guide roller 13 located on the outside of the curved rail 1. The cylinder piston rod 18 is connected between the end of the connecting pin 19' between one clamp claw 17 and the locking cylinder 18, and the end of a threaded rod 21 with an ear piece 20 protruding from the inner surface of the side plate 11' of the frame 11. ' A spring 22 for pulling back is attached (this way, a single-acting cylinder can be used. Therefore, such a spring is not necessary in the case of a double-acting cylinder). 23 is a bracket for connection with the horizontal feed cylinder 6; 24 is a handle for carrying; 25
is the stopper bolt of the clamp claw. In addition,
Each device operated using hydraulic oil is connected to piping and controlled from a remote location.

According to the device having such a configuration, when it is transported to a work site and placed on the curved rail 1 assembled on the main rail R as shown in FIG.
is mounted and connected by a connecting rod 5, and a reaction force holding device 10
A clamp frame 11 is also mounted thereon and connected to the transverse carriage 2 by a transverse cylinder 6. Of course, each cylinder 6, 18 and jack 4 are operable and located under the derailed vehicle. After lifting the derailed vehicle using the hydraulic jack, first feed hydraulic oil into the locking cylinder 18 and push out the piston rod 18', then the two connecting clamp claws 17, 17 will automatically synchronize and lock the curved rail. The clamp frame 11 is fixed to the curved rail 1 by abutting on both inner sides of the rail 1 and a guide receiving roller 13 located on the outer side. Therefore, when the transverse feed cylinder 6 is actuated to move the piston rod forward, the transverse feed carriage 2 connected to the frame 11 with a reaction force moves forward by one stroke of the cross feed cylinder 6. The derailed vehicle being lifted up by this transverse carriage 2 and the other transverse carriage 2' connected by a connecting rod 5 via their respective hydraulic jacks 4 is pulled onto the track R. Next, when the operating pressure to the locking cylinder 18 is released, the piston rod 18' is moved back by the force of the return spring 22.
The clamp claws 17, 17 are pulled back, and the roller 13
The clamping force is eliminated and the clamp frame 11
is unfixed.

Therefore, when the rod of the cross-feeding cylinder 6 is moved backward, the clamp frame 11 is moved against the guide roller 1.
4 and 14, it is pulled toward the traverse carriage 2 on the curved rail 1. When the clamp frame 11 moves by one stroke of the cross-feeding cylinder 6, the locking cylinder 18 is operated again and the clamp claw 1 is moved.
7, 17 and guide receiving rollers 13, 13 to clamp the rail, and the clamp frame 11
is fixed, and when the transverse feed cylinder 6 is operated to project the rod one stroke, the transverse feed carriages 2, 2' move. Thereafter, the derailed vehicle can be returned to the main track R along the curved rail 1 by alternately repeating the clamp operation/unclamp operation of the locking cylinder 18 of the clamp frame and the expansion/contraction operation of the cross-feeding cylinder 6. Then, by lowering the hydraulic jacks 4 all at once, the wheels of the derailed vehicle can be returned to the track.

After work, each part of the device can be disassembled individually and easily removed.

Effects of the invention: In the device of this invention, the movement reaction force during traversing operation is absorbed by the two clamp claws skillfully incorporated to connect the locking cylinder and the locking cylinder, and the guide attached to the outside. It can be secured by fixing the curved rail without a separate locking means by using a clamp frame with rollers, and by alternately expanding and contracting this clamp frame and the transverse feed cylinder connected to it. Since it is now possible to perform horizontal feed, the manual operation required in the past is reduced.
Return operations can now be performed remotely by centralizing the control panel, ensuring safety and saving labor, shortening and streamlining work time.
