Abstract

The invention discloses a hydraulic rail-changing machine, which belongs to the technical field of rail-changing devices and is designed to solve the problems of inconvenient use of existing large-scale rail-changing devices and low efficiency of manual rail-changing work. The hydraulic rail changing machine of the present invention comprises a main frame arranged horizontally, on which are installed a clamping assembly for clamping the rail to be replaced, a translation assembly for carrying the rail to be replaced and a lifting assembly for lifting and lowering the rail to be replaced, The clamping assembly can move horizontally along the main frame; the clamping assembly, translation assembly and lifting assembly are all driven by hydraulic cylinders, and the clamping assembly, translation assembly and lifting assembly are controlled independently by different hydraulic control valve groups. The hydraulic rail changing machine of the present invention can quickly remove and lay steel rails during rail changing operations in public works. Compared with large-scale rail changing vehicles, the hydraulic rail changing machine is more flexible, more economical, and can be used in a wider range; compared with manual operations, the hydraulic rail changing machine has high working efficiency, can reduce manpower and labor intensity.

Description

technical field [0001] The invention relates to the technical field of rail changing operation devices, in particular to a hydraulic rail changing machine. Background technique [0002] During the operation of the railway, the train has to run repeatedly on the rails. After a long time, the rails will be gradually worn and consumed, causing various damages to the rails, such as hole cracks, rail head cracks, falling blocks, peeling and nuclear damage, etc. serious negative impact on safety. The failed rails damaged in sections must be replaced to ensure driving safety. [0003] At present, when the public works system replaces the rail operation, it either relies on manpower or uses a rail changing car. The rail changing car is a large-scale rail maintenance machine. The product price is high, and the use and maintenance costs are relatively high. Generally, it is only equipped in large-scale public works stations. Large-scale rail change vehicles are mostly used during t...
