Description

  The present invention relates to a track traveling vehicle.

Conventionally, a plurality of units consisting of a base stand with a lateral feed mechanism and a hydraulic jack that can be mounted upwards thereon are mounted on, for example, a motor car (towing vehicle) and pulled by this motor car. If the truck is derailed, take out the unit mounted on the motor car, set the base stand (with a packing plate, etc.) on the roadbed below the derailed truck, A hydraulic jack was mounted upward on the base stand and jacked up. At this time, the unit composed of the base base and the hydraulic jack uses (at least) a pair of left and right, and after the jack is up, the lateral feed mechanism of the base base is operated by the left and right workers, respectively. Moved sideways to restore derailment.
However, the unit has a considerable weight, and it is difficult and troublesome for the operator to carry it to a trolley car and to set it on the lower roadbed.
Therefore, in order to solve such a conventional problem, a patent application has been filed once (see Patent Document 1).
That is, a lateral feed base provided on the lower surface side of the vehicle base so as to be slidable in the left-right direction and capable of positioning, and a left-right horizontal screw rod pivotally attached to the lateral feed base so as to be rotatable around a horizontal horizontal axis. And an assembly member for attaching a hydraulic jack to each of the left and right sides of the vehicle base. When the vehicle derails, After pulling out and positioning (fixing), attach hydraulic jacks to the left and right assembly members, attach operating ratchet levers to the left and right screw rods, jack up the vehicle base, Workers placed on the left and right sides of the car swing the ratchet lever while talking to each other, rotate the screw rod around the horizontal axis, and feed the vehicle base horizontally until the wheel is positioned above the rail. For devices that restore derailment , It has filed a patent application.

This adjustment fastener is provided on each of the left and right sides of the hydraulic jack 29 and the assembly member 23.

Next, an operation (usage method) of the track traveling vehicle according to the present invention will be described.
As shown in FIG. 8, when the vehicle base 1 is derailed, first, as a derailment recovery setup operation, the lateral feed in the storage state on the side where the operation obstacle such as the vehicle support member 18 does not protrude (one on the left and right sides) The base 21 (21A) is pulled out and positioned and fixed with the stopper pin 26 (see FIG. 7). When the left or right lateral feed base 21A is pulled out, the first member 31 slides on the second member 32 and moves to the left or right side, so that the connecting member 3 extends, and the left and right other lateral feed base 21 (21B). ) Is fixed by the stopper pin 26 and the stored state is maintained.

  The hydraulic jacks 29 and 29 are attached to the left and right assembly members 23 and 23, respectively. Further, a ratchet lever 27 is attached to one end 22a of the first screw rod 22A, and a lever guide 28 is attached to the lateral feed base 21A that has been pulled out.

  9 and 10, after attaching the hydraulic jack 29, the ratchet lever 27, and the lever guide 28, the ratchet lever 27 is operated so that the left and right assembly members 23 (23A) and the hydraulic jack 29 ( 29A) is disposed in the vicinity of the left and right outer sides of the rail r. The torque for rotating the first screw rod 22A is transmitted to the second screw rod 22B via the connecting member 3, and the second screw rod 22B also rotates (the first screw rod 22A and the second screw rod 22B Since the winding direction, screw shape, number of threads, pitch, and diameter of the screw are the same), the left and right other assembly member 23 (23B) and the hydraulic jack 29 (29B) are the left and right one assembly member 23A and the hydraulic jack. Synchronize with 29A (Screw by the same amount at the same speed in the same direction).

  After the arrangement of the hydraulic jack 29 is completed, a manual type hydraulic pump (not shown) is connected to the hydraulic jack 29. Further, a block-like or plate-like laying member (packing member) 25 is disposed below the hydraulic jack 29.

  After the above derailment recovery setup operation, the hydraulic jacks 29 and 29 are extended by operating the hydraulic pump. Until the wheel 19 is positioned above the upper surface of the rail r, the extension work of the hydraulic jack 29 and the receiving work of the vehicle base 1 using the laying member 25 are performed (jack-up work).

After a jack-up operation, when one worker placed on the left or right side swings the ratchet lever 27 attached to the first screw rod 22A back and forth, the operating force (torque) around the left and right horizontal axis is The first screw rod 22A is transmitted to the second screw rod 22B via the connecting member 3, and the first screw rod 22A and the second screw rod 22B are synchronized (rotated in the same direction at the same speed).
Since the left and right assembly members 23A and 23B and the hydraulic jacks 29A and 29B are in a fixed state in which they are prevented from moving in the left and right directions under load, the left and right screw rods 22A and 22B are rotated by the rotation of the first and second screw rods 22A and 22B. Each of the lateral feed bases 21A and 21B and the guide rail members 20A and 20B and the vehicle base 1 are laterally fed (screwed) integrally. The lateral movement amounts on the left and right sides of the vehicle base 1 are the same, and the lateral movement is stable. The vehicle is laterally fed until the wheel 19 is positioned above the rail r (lateral feeding operation).

  Further, in the lateral feed operation, the operation can be performed on the side where the operation obstacle such as the vehicle support member 18 is not overhanging. Therefore, it is possible to attach the pipe-shaped extension lever 24 to the handle portion of the ratchet lever 27. . The extension lever 24 can reduce the burden on the operator.

After the transverse feed operation is completed, the left and right hydraulic jacks 29, 29 are shortened, and the wheel 19 is placed on the rail r.
Disconnect the hydraulic jack 29 from the hydraulic pump, disengage the hydraulic jack 29, the lever guide 28, and the ratchet lever 27, place the lateral feed base 21 in the stowed state (storage position), and fix the positioning. It is assumed that the vehicle is ready for traveling.
Although not shown in the drawing, when there is an operation obstacle on the left and right other side, the left and right lateral feed base 21A is set in the retracted state, the left and right other horizontal feed base 21B is pulled out and the ratchet lever 27 is attached. It is also possible to perform derailment recovery work.
