Abstract

The invention discloses a clamping device and a polishing positioning device, which are invented for solving the problems of the prior art, such as low polishing efficiency and the like. The clamping device comprises a first connecting plate and a clamping plate which are connected in turn and further comprises a second connecting plate, a spring plate device and a hydraulic driving brake which are also connected in turn, wherein the spring plate device comprises two sets of spring plates which are arranged oppositely; clapboards are arranged on two sides between the spring plates; one set of the spring plates is connected to the second connecting plate; the other set of the spring plates is connected to the hydraulic driving brake; and the clamping plate is arranged between two hydraulic cylinder pistons of the hydraulic driving brake and is matched with the hydraulic driving brake. The clamping device can be used for fixedly connecting two polishing devices, and the two polishing devices are in rigid connection along a vertical direction and are in elastic connection along a horizontal direction, thereby increasing a polishing operation surface of the polishing devices and realizing the polishing repairing for waveform abrasion of a steel rail.

Description

technical field [0001] The invention relates to a rail grinding technology, in particular to a clamping device and a grinding positioning device. Background technique [0002] At present, my country's railway has entered a period of rapid development. In 2010, the national railway operating mileage reached more than 90,000 kilometers. It is estimated that the national railway operating mileage will reach 120,000 kilometers by the end of the "Twelfth Five-Year Plan". With the development of high-speed and heavy-duty railways in China, more stringent requirements are put forward for the safety, comfort and transportation capacity of railway lines. Rail grinding, as an important method of railway maintenance and maintenance in the railway engineering department, has reached a relatively perfect application stage and has produced huge economic benefits. [0003] The existing rail grinding device includes a support, a rotating mechanism and a motor with a grinding wheel. The fix...
