A wheel set unloading machine with a wheel unloading seat with a key structure that can be used in both directions

Abstract

The invention discloses a wheel set withdrawing machine provided with a clamping key structure wheel withdrawing seat capable of being used bi-directionally. The wheel set withdrawing machine comprises a base, a withdrawing hydraulic cylinder, two side pulling plates, two linear rails, two jacking air cylinders and the wheel withdrawing seat; the withdrawing hydraulic cylinder is arranged at one end of the base; a flexible ejecting head is arranged at the output end of the withdrawing hydraulic cylinder; the wheel withdrawing seat is arranged in the middle of the base; the withdrawing hydraulic cylinder and the wheel withdrawing seat are fixedly connected together by the aid of the two side pulling plates from two sides; the two linear rails are separately arranged on two sides of the wheel withdrawing seat; and the two jacking air cylinders are movably arranged on the linear rails correspondingly. The wheel set withdrawing machine has the advantages that the provided wheel withdrawingseat is reasonable in structure, good in manufacturability and high in strength, the stable and effective use condition of the large withdrawing force up to hundreds of tons during wheel withdrawingcan be met, the requirement for withdrawing of a brake disc provided with two or three brake disc wheel sets can also be met through adjustment of the direction of the wheel withdrawing seat, and thusthe operations of wheel withdrawing and brake disc withdrawing are realized reliably.

Description

Technical field [0001] The invention relates to the field of wheel-set disassembly equipment, and in particular to a wheel-set unloading machine with a wheel-retracting seat with a two-way use card key structure. Background technique [0002] Railway vehicle wheelsets are usually divided into two categories: passenger car wheelsets and freight car wheelsets. The main difference between the two is that the wheelsets for freight cars are not equipped with brake discs. It consists of two wheels that are press-fitted on the axle wheels in an interference fit. The seat part, and the passenger car wheel set must be press-fitted with two or three sets of brake discs in the two-wheel opening gear. In the unloading operation of the wheelset, the unloading force of the wheel is very large, some can reach more than 400 tons, and the brake disc can usually be withdrawn from tens of tons. [0003] The main problems existing in the existing reversing equipment are as follows: [0004] First, the...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a wheel set unloading machine with a two-way use card key structure unloading seat, which solves the problem that the traditional wheel set unloading machine cannot unload the wheel set with the brake disc. The defect of elastic deformation due to the concentration of load at the bearing jaw
