Hydraulic switches track-lifting and shifting machine

Abstract

The present invention relates to a hydraulic rail-lifting track-shifting machine, consisting of machine unit, track-hooking device, rail-lifting device, track-shifting device, main machine rotating device and power system, etc. in which the main unit is formed from cross-beam and oil tank, the sleeve of the track-hooking device is cover-mounted on the track hook, the track hook is connected with lifting oil cylinder by means of nut, the track-hooking rolling frame is connected with horizontal track-hooking oil cylinder, two large offset oil cylinders of the rail-lifting device are respectively fixed on two rail-lifting rolling frames, and the horizontal track-shifting oil cylinder is fixed on the cross-beam of machine body and connected with pulling rod.

Description

Technical field: [0001] The invention belongs to the technical field of railway turnout lifting equipment, in particular to a hydraulic track opening machine. Background technique: [0002] Before the present invention was made, the turnout equipment used by my country's railway engineering department mainly contained manual hydraulic track setters, or adopted foreign large-scale tamping machines as auxiliary track setters. Among them, the disadvantage of the manual hydraulic track lifter is that the track force is small, each track force is less than 200KN, and more than four machines are required to work at the same time during operation, which requires a lot of manpower, and manual operation is required. The pump makes the oil cylinder move to complete the lifting operation, and the operation efficiency is low. At the same time, the machine is limited by the structure and the lifting amount is small, only 110mm, and the total moving amount is only 50mm, which cannot meet ...

Problems solved by technology

Among them, the disadvantage of the manual hydraulic track lifter is that the track force is small, each track force is less than 200KN, and more than four machines are required to work at the same time during operation, which requires a lot of manpower, and manual operation is required. The pump makes the oil cylinder move to complete the lifting operation, and the operation efficiency is low. At the same time, the machine is limited by the structure and the lifting amount is small, only 110mm, and the total moving amount is only 50mm, which cannot meet the large lifting amount of the turnout and the moving operation. Need; while the foreign large-scale tamping machine is attached to the track setting device is installed in the middle of the tamping car, the running wheel of the tamping machine is pressed on the switch rail when starting the track, and the track setting device can only be used in a limited The operation within the range cannot meet the needs of the large-scale operation of the turnout and the large-scale operation of the track. The device cannot meet the needs of the new laying and overhaul of the turnout.
