Fully automatic wheel set unloading machine

Abstract

The invention discloses a fully automatic wheel set withdrawal machine. The fully automatic wheel set withdrawal machine comprises a rack, stop dog devices, a hydraulic and electrical control system. The middle portion of an upper cross beam and the middle portion of a lower cross beam of the rack are correspondingly provided with bosses. Main oil cylinder devices are symmetrically arranged in a left fixing beam and a right fixing beam of the rack respectively. A centre device is arranged in the front of a main oil cylinder piston rod. The quantity of the stop dog devices is two. The stop dog devices are symmetrically arranged on the left side and the right side in the rack respectively. Each stop dog device is provided with a stop dog body. The upper portion of each stop dog body is connected with a straight line guide rail and a moving oil cylinder. The straight line guide rails and the moving oil cylinders are arranged on the cross beam of the rack. A U-shaped opening of each stop dog body is opened in a sidewards manner, and each stop dog body is provided with grooves used for entering of a wheel and a braking disc. According to the fully automatic wheel set withdrawal machine, the withdrawal efficiency and precision can be improved, the wheel and the braking disc can be simultaneously withdrawn at a time, and the time is saved. Due to automatic centering positioning, it is guaranteed that parts are prevented from being damaged during the withdrawal process, the precision is not influenced, economic losses are prevented, and the fully automatic wheel set withdrawal machine is beneficial to an assembling production line.

Description

technical field [0001] The invention relates to special machinery equipment for railways, which is suitable for withdrawing and unloading train wheel sets with brake discs, and belongs to a full-automatic wheel set unloading machine. Background technique [0002] In recent years, manufacturers at home and abroad have successively launched special railway wheel set unloading machines to solve the unloading of wheels, axles and brake discs after the train speeds up. Some of these models have a single function, and the wheels and brake discs need to be unloaded step by step, which takes a long time and is inefficient; although some have the function of unloading the wheels and brake discs at the same time, after the wheels are on the machine, there is no The top device cannot be automatically aligned mechanically, and needs to be manually aligned. Not only is the operation cumbersome, but the accuracy cannot be guaranteed. If there is a slight difference, there will be awkwardn...

Problems solved by technology

Some of these models have a single function, and the wheels and brake discs need to be unloaded step by step, which takes a long time and is inefficient; although some have the function of unloading the wheels and brake discs at the same time, after the wheels are on the machine, there is no The top device cannot be automatically aligned mechanically, and needs to be manually aligned. Not only is the operation cumbersome, but the accuracy cannot be guaranteed. If there is a slight difference, there will be awkwardness during the unloading process, and the axle, brake disc, and wheel set cannot be guaranteed to be free from damage. , which will directly cause economic losses
