Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a derailment restoration lateral feed device for promptly restoring a vehicle to a main rail when the vehicle derails in a tunnel or the like.

[0002]

2. Description of the Related Art When a conventional vehicle derails from a rail,
Push the vehicle horizontally to a certain height by operating the manual hydraulic pump using the fixed jacks arranged on the left and right, then stack the sleepers on the roadbed, and further install the transverse feed stand with the feed screw shafts on the sleepers. Then, after mounting a jack on the horizontal feed table and pushing up to the position where the wheels on the vehicle dodge the rail top surface with this jack, the jack on the horizontal feed table is screwed by the screw shaft installed horizontally on the horizontal feed table. It was fed sideways and the vehicle was restored on the rail.

[0003]

In the conventional means for restoration, the vehicle is laterally moved by the screw shaft of the transverse feed table. However, there is a possibility that the sleepers may sink due to the softness of the roadbed and the vehicle may fall over. Need to unload once and reload the sleepers. Therefore, it takes time to perform the work, and further, in order to move the screw, the screw shaft operation of the horizontal feed table is operated by two persons separately, so that it is often the case that the same force is not performed at the same time. Had various inconveniences.

SUMMARY OF THE INVENTION According to the present invention, a pair of frames having guide rails on the lower surface are installed at a distance from each other and fixed to a vehicle, and a rack shaft is slidably fitted on the frame. , The rack jack main body having a pinion that meshes with the teeth of the rack shaft is erected and fixed, and the center of the feed member is connected to the rack shaft, and at the same distance left and right centered on the connecting portion of the feed member. A receiving member for setting the head of the jack on the lower surface is provided at each position, and the connecting pieces of the moving bases that move along the guide rails are connected to each other, and the rack jack main body laterally moves the pair of moving bases in the derailing direction. It is intended to provide a derailment-recovery transverse feed device that speeds up work by performing feeding.

When the wheel 2 of the vehicle 1 derails from the rail, the manual hydraulic pump 19 is closed by the flow rate adjusting cutoff valves 20, 20a, 20.
b, 20c and connected to a four-way branch 21 and each branch pipe of the four-way branch 21 is connected to a hose 22, 22.
a, 24, 24a are connected to the fixed jacks 18 and 18a and the jacks 15 and 16 mounted on the sleepers 23 and 23a, and the fixed jacks 18 and 18a are preset to the left and right corresponding positions of the vehicle 1 (see FIG. 5). Further, after setting the fixed jacks 18 and 18a, the shutoff valves 20 and 20a provided on the branch 21 are opened, and the manual hydraulic pump 19 is operated to raise the wheels 2 of the vehicle 1 to the extent that they exceed the upper surface of the rail R. Shut-off valve 2 for the holes sent to the fixed jacks 18 and 18a
Close 0 and 20a.

After the supply of the fixed jacks 18 and 18a has been stopped, the jack receiving member 17 of the transverse feed base A of the vehicle 1 is moved in the reverse direction in which the wheels have been derailed, and the sleeper 23 is associated with the receiving member 17 at this moving position. , 23a, and sleepers 2
Heads 15a of jacks 15 and 16, respectively on 3,23a,
16a are respectively set on the receiving members 17 (see FIG. 6), and the shutoff valves 20b, 20c connected to the jacks 15, 16 provided on the four-way branch 21 are opened to open the manual hydraulic pump 1
Fixed jacks 18 and 1 by jacks 15 and 16 by 9
Push up until 8a loosens. At this time, jacks 15 and 16
Is adjusted so that the cutoff valves 20b and 20c are adjusted so that the cutoff valves are leveled horizontally.

Further, when the jacks 15 and 16 are pushed up, the shut-off valves 20b and 20c are closed to keep the pushed-up state, and then the rack jack for laterally feeding the lateral feed table A fixed to the vehicle 1. Pinion shaft 8a provided on the main body 6
The ratchet handle 9 is set on and the movable bases 14 and 14 are simultaneously started to move laterally at the same time by rotating the handle 9 via the feed member 11 connected to the rack shaft 7 to a predetermined position. Shut-off valves 20b and 2 which are connected to the jacks 15 and 16 after moving 14 and 14
0c is gradually lowered onto the rail R while adjusting 0c so that the vehicle 1 becomes horizontal, and the wheels 2 are restored and completed (see FIG. 7).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a derailment recovery transverse feeding device according to the present invention, which will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a vehicle having wheels 2, which run on rails R. A transverse feed base A is laterally fixed to the rear side of the wheel 1. This lateral feed platform A includes a pair of frames 3, 3
The a is fixed laterally to the vehicle 1 with a space therebetween.

Further, on the lower surface of each of the frames 3 and 3a,
Guide rails 5 and 5a provided with guide grooves 4 and 4a at corresponding positions
Are horizontally installed along the frames 3 and 3a, respectively, and a horizontal feed rack jack main body 6 is installed between the frames 3 and 3a and fixed by an L-shaped frame 6a.

The lateral feed rack jack body 6 has a rack shaft 7
Is horizontally slidably fitted to the frame 3, and a pinion 8 adapted to mesh with the rack tooth portion 7a of the rack shaft 7 is supported by a bearing. The pinion shaft 8a has its end exposed to the outside and a ratchet. The handle 9 is fitted to transmit the rotation.

The traverse table A is constructed so that the rack jack body 6 is attached to one end of a protective cylinder 10 that covers the rack shaft 7 so that a part of the rack shaft 7 can be stored.

The tip end of the rack shaft 7 is connected by a pin 12 to a connecting plate 11a of a feeding member 11 which is formed in a triangular shape in the central portion and protrudes. Further, the feeding member 11 is a center line of the connecting plate 11a. The connecting holes 11b, 11b are drilled at positions equidistant from each other around the center of the connecting holes 11b, 11b.
And sliding bases 13, 1 slidably fitted on the guide rails 5, 5a.
A connecting member 14a from the movable bases 14 and 14 attached to 3a is connected by connecting pins 25 and 25, respectively, and by lateral movement of the rack shaft 7, the feed member is connected to the rack shaft 7 via a pin 12. The movable bases 14, 14 that are in contact with 11 are guided by the guide rails 5, 5a to be moved left and right.

Receiving members 17 and 17 for setting heads 15a and 16a of jacks 15 and 16 to be described later are provided on the moving bases 14 and 14, respectively.

Reference numerals 18 and 18a denote fixed jacks installed on the left and right sides of the vehicle 1. The fixed jacks 18 and 18a are connected to a manual hydraulic pump 19, and the flow control cutoff valve 2 is provided.
The four-way branch 21 provided with 0, 20a, 20b, and 20c and the hoses 22 and 22a are connected. Also, 2
3 and 23a are sleepers, and the jacks 15 and 16 are mounted on the sleepers 23 and 23a.
5 and 16 are the four-way branch 19 and hoses 24 and 24a
I have contacted you.

[0016]

As described above, according to the present invention, the transverse feed table having the rack jack main body is attached to the vehicle.
Therefore, even if the roadbed is in poor condition, only the jack on the inclined side needs to be raised, and it is not necessary to reload the sleepers as in the conventional case where the sleepers sink and tilt. Further, in the lateral feeding, the pair of moving bases are moved at a time by the rack jack main body through the feeding member, so that there is no imbalance as in the case of being operated by two people as in the conventional case, and the moving can be performed on average. Further, since the transverse feed table is attached to the vehicle and is not exposed to the outside from the vehicle, only jacks can be used for work or carrying in a narrow place such as a tunnel, so that work can be performed quickly and recovery is quick.
