Vehicle lifting pin base of railway vehicle and using method for vehicle lifting pin base

Abstract

The invention discloses a vehicle lifting pin base of a railway vehicle, and a using method for the vehicle lifting pin base, and belongs to the field of railway vehicles, and the vehicle lifting pin base realizes vehicle lifting operation and vehicle dropping operation without dismounting an anti-yaw damper base. The vehicle lifting pin base comprises a pedestal, a regulating wedge, a plug pin, a handle and a buckle plate, wherein the width and the height of the pedestal are separately smaller than the width and the height of a vehicle lifting hole; the length of the pedestal is greater than the thickness of the vehicle lifting hole; the two ends in a length direction of the pedestal are separately an inner end and an outer end; the inner end is provided with a pin hole in a width direction; a pin matched with the pin hole is arranged in the pin hole; the bottom surface of the outer end is provided with the buckle plate capable of being buckled on a vehicle lifting arm; the part, before the buckle plate, of the lower surface of the pedestal is upward in the shape of step; the length of a transverse step surface adjacent to the buckle plate is equal to the thickness of the vehicle lifting hole; the position, close to the outer end, of the upper surface of the pedestal is of an inclined surface which is thinned outwards; the regulating wedge is arranged on the inclined surface; and the two adjacent surfaces of the regulating wedge and the inclined surface are separately distributed with saw teeth which are matched. By virtue of the vehicle lifting pin base, the vehicle lifting operation and the vehicle dropping operation are safe, efficient, convenient and quick.

Description

Technical field [0001] The invention relates to a tooling for rail vehicles and a method of use thereof, in particular to a tooling and methods of use used when the rail vehicle is lifted and dropped. Background technique [0002] When a high-speed EMU is newly built, the vehicle needs to be lifted to facilitate the assembly of various components on the vehicle. The lifting parking space is set on the installation surface of the anti-snake damper seat on both sides of the car body bolster, and the anti-snake damper seat is installed after the vehicle is newly built. [0003] When the high-speed EMUs are overhauled, especially the four-level and five-level repairs, the anti-snake damper seat needs to be overhauled, so the original lifting method of the newly built EMUs needs to be disassembled. Only after the shock absorber seat can be lifted and dropped. However, in maintenance such as the three-level maintenance program, there is no need to perform maintenance on the anti-snake ...

AI Technical Summary

Problems solved by technology

Removing and installing the anti-snake shock absorber seat only for lifting and lowering the vehicle not only leads to inefficiency, but also tends to cause unnecessary bumps and other safety hazards during the disassembly process
