Righting machine for tunnel vehicle

Abstract

The invention discloses a righting machine for a tunnel vehicle, and relates to a righting machine. The righting machine comprises an inclined accident carriage, righting hook plates, jacking oil cylinders, supporting oil cylinders and anti-skid pad plates, the oil cylinders are arranged at the four corners of the lower portion of the accident carriage, the two oil cylinders at one same side are the jacking oil cylinders, and the two oil cylinders at the other side are the supporting oil cylinders; the jacking oil cylinders are arranged at the lower portion of the portion, at the low inclinedsurface, of the accident carriage, the accident carriage is connected with the jacking oil cylinders and the supporting oil cylinders through the righting hook plates, the lower portions of the jacking oil cylinders and the lower portions of the supporting oil cylinders are provided with base plates connected through pin shafts, and the base plates are arranged on the anti-skid pad plates or placed on a whole ballast bed; the righting machine is convenient to assemble, safe and reliable, and the reset and return speed of the inclined accident carriage is controlled through a speed control valve arranged on a control valve set of a high-pressure pump station.

Description

technical field [0001] The invention relates to a straightening tool, in particular to a tunnel vehicle straightening tool. Background technique [0002] As we all know, with the development of railway transportation, railway tunnels are becoming more and more common, which means that the possibility of railway traffic accidents in tunnels increases accordingly. One of the forms of railway traffic accidents in tunnels is when the vehicle goes off-line. Tilting against the tunnel wall, this requires a rescue device to straighten the tilted vehicle; currently there is a straightening machine that can straighten the tilted vehicle, but the disadvantage of this kind of straightening machine is that after the vehicle is straightened to a certain extent, Completely relying on self-resetting, it will cause great damage to the vehicle and the line, and may cause the vehicle to tilt twice, and there is a certain risk; therefore, it has become a challenge for those skilled in the art ...
