A kind of railway track special grinding and cleaning intelligent all-in-one machine

Abstract

The invention relates to an intelligent polishing and cleaning integrated machine special for a railway track. The intelligent polishing and cleaning integrated machine comprises a parallel-connection supporting mechanism, and the parallel-connection supporting mechanism comprises a fixed platform. Three parallel-connection branch chains are evenly installed on the lower end face of the fixed platform in the axis direction. The top ends of the three parallel-connection branch chains are all installed on a movable platform. A self-stabilizing mobile device is welded to the lower end face of the movable platform, and the self-stabilizing mobile device can achieve stable self-adjustment of the polishing direction according to the bending shape of the railway track. A variable high-pressure cleaning device is installed on the lower end face of the self-stabilizing mobile device, can quickly remove residual polishing scrap iron and unremoved dust adhering to the railway track based on the working principle of high-pressure water jetting, and has a good high-pressure cleaning effect. Four fourth hydraulic cylinders are symmetrically installed at the lower end of the variable high-pressure cleaning device. An adjustable polishing device is installed at the top ends of the four fourth hydraulic cylinders. The adjustable polishing device can carry out polishing back and forth by being completely attached to the surface of the railway track. The intelligent polishing and cleaning integrated machine can achieve the full-automatic railway track polishing and cleaning functions, is free of manual operation and is high in degree of automation.

Description

technical field [0001] The invention relates to the technical field of rail processing, in particular to an intelligent all-in-one machine for grinding and cleaning rails. Background technique [0002] 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 many burrs on the surface, and the smoothness of the rail is poor; 2. Secondary welding is required between the 100-meter long rails, but after welding The welding points under the rail are extremely uneven on the track, which affects the smoothness of the rail; 3. The rails in use may be corroded for a long time and may also produce rust sp...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides an intelligent all-in-one machine for grinding and cleaning railway tracks, which can solve the problems of manual operation, low degree of automation, slow grinding and cleaning speed, and equipment work that exist in existing rail grinding and cleaning equipment. There are vibrations during the process, poor equipment stability, uneven grinding force, poor grinding effect, poor self-adjustment performance in the grinding direction, difficulty in fully attaching the equipment to the rail surface, small grinding range, small application range, and cleaning effect of residual grinding iron filings Poor and low work efficiency and other problems, can realize the automatic grinding and cleaning function of the rails, without manual operation, high degree of automation, eliminates the vibration during the working process of the equipment, good stability of the equipment, and has fast grinding and cleaning speed, and the grinding direction Good self-stable adjustment performance, the equipment can be completely attached to the rail surface, large grinding range, wide application range, good high-pressure cleaning effect of residual grinding iron filings and high work efficiency, etc.
