Embodiment Construction

[0015] Such as figure 1 , figure 2 As shown, the electro-hydraulic dismounting machine for the coupler buffer device of the railway locomotive is composed of a driving frame 10, a hydraulic dismounting mechanism assembled at the front of the driving frame 10, and a hydraulic pressure-bearing mechanism assembled at the rear, and the rear of the driving frame 10 The front part is equipped with two universal wheels 1, and the front part is equipped with two directional wheels 8 in the front and rear directions. The front part of the car is equipped with a frame lifting mechanism. The directional wheel 11 of left and right directions, two piston rods of vehicle frame lifting oil cylinder 9 are hinged with lifting rotating support. The hydraulic cylinder of the above-mentioned hydraulic pressure-bearing mechanism adopts a double-stage double-acting telescopic cylinder 2, and the top of the piston rod of the cylinder 2 is equipped with a pressure-bearing support 3. The assembled ...

Abstract

The present invention discloses an electric hydraulic replacer for railway rolling stock coupling buffer device. It is formed from carriage frame, hydraulic replacing mechanism for carriage frame front assembly and hydraulic pressure-bearing mechanism for rear assembly. The hydraulic cylinder of the above-mentioned hydraulic pressure-bearing mechanism adopts double-stage double-action telescopic cylinder, the top portion of piston rod of the cylinder is equipped with pressure-bearing support. The above-mentioned hydraulic replacing mechanism is formed from supporting lifting cylinder, supporting mounted on the top of piston rod of support lift cylinder, claw hook mechanism assembled on the middle portion of support and two hook-removing cylinders symmetrically assembled on the support at two sides of claw hook mechanism.

Description

technical field [0001] The invention relates to an electro-hydraulic dismantling machine for coupler buffer devices of railway locomotives and vehicles for disassembling and assembling operations. Background technique [0002] With the rapid development of the railway transportation industry, freight trains are heavy-loaded and speed-up, and higher requirements are put forward for the quality standards and tooling equipment of freight trains. After the freight trains are heavy-loaded, the failures increase significantly. Replace the coupler buffer during the station repair operation. The workload of the device is increased, but most station repairs still rely on manual replacement of the coupler buffer device, or use simple devices to disassemble the coupler buffer device. There is no special equipment, the labor intensity is high, and the work efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide an electro-hydraulic dism...
