Wheel set withdrawing machine provided with clamping key structure wheel withdrawing seat capable of being used bi-directionally

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 dismantling equipment, in particular to a wheel set unloading machine with a two-way usable key structure wheel unloading seat. Background technique [0002] Wheel sets for railway vehicles are usually divided into two categories: wheel sets for passenger cars and wheel sets for freight cars. The main difference between the two is that the wheel sets for freight cars are not equipped with brake discs. Seat position, and the wheel set for passenger cars must also be press-fitted with two or three sets of brake discs in the second wheel gear. When the wheelset is unloading, the wheel unloading force is very large, some can reach more than 400 tons, and the brake disc can usually be withdrawn by tens of tons. [0003] The main problems that exist in the existing wheel-removing equipment have the following two points: [0004] First, the existing wheel-removing machine with fixed wheel-removing seat can onl...

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
