Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0028] This embodiment discloses a hydraulic rail changer. Such as Figure 1 to Figure 6 As shown, the hydraulic rail changer includes a horizontally arranged main frame 1. The main frame 1 is equipped with a clamping assembly for clamping the rail 5 to be replaced, a translational assembly for transporting the rail 5 to be replaced, and for lifting and lowering the rail 5 to be replaced. The lifting assembly of the rail 5, the engine 6 and the hydraulic oil tank 7, the clamping assembly can move horizontally along the main frame 1. The clamping assembly, translation assembly and lifting assembly are all driven by hydraulic cylinders, and the clamping assembly, translation assembly and lifting assembly The lifting components are controlled independently of each other without interference by different hydraulic control valve grou...

Abstract

The invention discloses a hydraulic rail changing machine, and belongs to the technical field of rail changing operation devices, aiming to solve the problems of existing large rail changing devices,such as inconvenience in use and low efficiency in manual rail changing work. The hydraulic rail changing machine comprises a horizontal main frame. A clamping component, a translation component and alifting component are mounted on the main frame; the clamping component is used for clamping a to-be-changed steel rail; the translation component is used for carrying the to-be-changed steel rail; the lifting component is used for lifting and dropping the to-be-changed steel rail; the clamping component can horizontally move along the main frame; the clamping component, the translation componentand the lifting component are driven by a hydraulic oil cylinder, and can be independently controlled by different hydraulic control valve groups. The hydraulic rail changing machine can rapidly remove and lay steel rails during public rail changing. Compared with large-scale rail changing vehicles, the hydraulic rail changing machine has the advantages of flexibility in use, economy, and wide application range; compared with manual work, the hydraulic rail changing machine has the advantages of high working efficiency, reduced manpower and reduced 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 must run repeatedly on the rail. After the time is reached, the rail will gradually wear and consume, causing various damages to the rail, such as hole cracks, rail head cracks, falling blocks, peeling, and nuclear damage. Safety has a serious negative impact. Damaged and failed rails must be replaced in sections to ensure driving safety. [0003] The current public works system either relies on manpower or uses rail-changing vehicles when replacing rails. The rail-changing car is a large-scale rail maintenance machine. The product price is high, and the use and maintenance costs are high. Generally, it is only equipped in large-scale public works stations. Large-scale rail-changing vehicles are mostly used during major repairs or when a large number...
