A rail clamping device

Abstract

The invention discloses a steel rail clamping device. The steel rail clamping device comprises a frame assembly, a support roller assembly and a clamping assembly, wherein the support roller assembly and the clamping assembly are both arranged on the frame assembly, the support roller assembly is used for bearing the weight of a steel rail, and the clamping assembly is used for clamping the steel rail. The steel rail clamping device is more convenient, effective and reliable to use and can improve the steel rail machining precision and machining percent of pass.

Description

technical field [0001] The invention relates to rail welding processing technology, more specifically, to a rail clamping device. Background technique [0002] With the rapid development of high-speed trains in China, the quality of the rails used for on-site laying is also becoming higher and higher. This requires that the rails must be processed at each station in the production line of the welding rail base, such as rough grinding. Work station, fine milling station, the machining accuracy of this processing equipment reaches the level of 0.01mm, so it is necessary to obtain an effective and reliable clamping when the rail is processed, so as to ensure that the steel rail meets the requirements of the factory standard of the steel rail after being processed by various equipment . [0003] Since the production line of the welding rail base is an assembly line operation mode, the equipment itself is required to have rail rollers at each rail processing station, and the rai...

Problems solved by technology

[0005] At present, in common equipment, the rail is clamped by clamping both sides of the rail waist 2 or the rail running surface 4 and the bottom surface of the rail bottom 3 on the rail head 1. This clamping method is easy for rail processing operations. When interference occurs, it is not easy to process, and the part of the rail head 1 is not exposed as much as possible.

In addition, the force generated by the existing rail clamping cylinder directly acts on the rail clamping. Due to the limitation of structural space, it is difficult to make the clamping cylinder large, and it is also difficult to increase the pressure of the hydraulic system to a high level. Therefore, the clamping force of the rail is very limited, so it is easy to produce deviation during the processing of the rail, which affects the processing accuracy and leads to the generation of unqualified rails
