Polishing and washing machine special for high-speed railway track

Abstract

The invention relates to a polishing and washing machine special for a high-speed railway track. The polishing and washing machine special for the high-speed railway track comprises a variable high-pressure washing device. The high-pressure washing direction of the variable high-pressure washing device can be adjusted, so that the polishing and washing machine is not affected in the polishing process; after polishing is completed, the high-pressure washing direction is adjusted so that the variable high-pressure washing device can work, residual polishing scrap iron and non-cleaned dust attached to the track are rapidly washed away through the high-pressure water jet working principle, and the high-pressure washing effect is good; the lower end of the variable high-pressure washing deviceis symmetrically provided with four fourth hydraulic cylinders, and the top ends of the four fourth hydraulic cylinders are provided with adjustable polishing devices; by means of the four fourth hydraulic cylinders, the polishing height of the polishing and washing machine can be adjusted; the variable high-pressure washing device comprises a washing support plate, the two sides of the lower endface of the washing support plate are symmetrically provided with two washing adjusting branch chains and two high-pressure washing branch chains, and the two washing adjusting branch chains are connected with the two high-pressure washing branch chains correspondingly. By means of the polishing and washing machine, the full-automatic polishing and washing functions of the track can be achieved, manual operation is not needed, and the automation degree is high.

Description

[0001] This invention is a divisional application of the Chinese invention patent application with the patent application number "201610493546.4" and the name "A special grinding and cleaning machine for high-speed train tracks" filed by the applicant on June 28, 2016. The entire content of which is incorporated in in this application. technical field [0002] The invention relates to the technical field of rail processing, in particular to a special grinding and cleaning machine for high-speed train rails. Background technique [0003] With the continuous development of high-speed rail technology, the quality requirements of rails are getting higher and higher. Since the speed of high-speed rails, bullet trains, and subways is much higher than that of ordinary trains, the smoothness of rails is highly required, and the main factors that affect the smoothness of rails There are the following aspects: 1. After the main body of the rail is produced and formed, there will be ma...

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a special grinding and cleaning machine for high-speed train tracks, which can solve the problems of manual operation, low automation, slow grinding and cleaning speed, and poor grinding effect in existing rail grinding and cleaning equipment. , It is difficult for the equipment to be completely attached to the surface of the rail, the grinding range is small, the scope of application is small, the cleaning effect of residual grinding iron chips is poor, and the work efficiency is low. It can realize the automatic grinding and cleaning function of the rail without manual operation and a high degree of automation. And it has the advantages of fast grinding and cleaning speed, good grinding effect, the equipment can be completely attached to the surface of the rail, large grinding range, wide application range, good high-pressure cleaning effect of residual grinding iron filings and high work efficiency.
