High-precision grinding machining device for high-speed railway industry

Abstract

The high-precision grinding machining device comprises an intelligent railway grinding system and a vehicle frame, a treatment box is installed on the vehicle frame, a steel rail is arranged below the vehicle frame, a plurality of rolling wheels are rotationally connected to the lower portions of the left side and the right side of the vehicle frame, and the surfaces of the rolling wheels make contact with the upper rail face of the steel rail. A plurality of grinding assemblies are arranged between the front and rear rollers, the grinding assemblies are uniformly distributed in the frame, each grinding assembly comprises a flitch plate, the flitch plates are fixed to the lower portion in the frame, the left side of the lower surface of each flitch plate is rotationally connected with a first fixing plate, and a vertical plate is fixed to the right side of the lower surface of each flitch plate; the side, close to the first fixing plate, of the vertical plate is rotationally connected with a hydraulic cylinder, the upper end of the first fixing plate is fixedly connected with a third motor, the interior of the hydraulic cylinder is slidably connected with a piston rod, and the problem that the upper rail surface of the current railway steel rail is not sufficiently polished is solved.

Description

technical field [0001] The invention relates to the technical field of railway maintenance, in particular to a high-precision grinding device used in the high-speed railway industry. Background technique [0002] With the continuous development of the high-speed rail industry, more and more passengers choose to travel by high-speed rail. When the high-speed rail industry is booming, track maintenance is becoming more and more important. Patent No. CN211285095U discloses a robotized rail grinding car, which solves the problems of low grinding precision and low grinding efficiency of traditional manual grinding machines by setting up a swinging mechanical arm, grinding components and electric components. It has good versatility and can complete rail grinding. Comprehensive grinding is beneficial for maintenance, but in the daily maintenance of rails, it cannot realize the intelligentization of rail maintenance. In the grinding of rails, the degree of wear on the top surface of...

Patent No. CN211285095U discloses a robotized rail grinding car, which solves the problems of low grinding precision and low grinding efficiency of traditional manual grinding machines by setting up a swinging mechanical arm, grinding components and electric components. It has good versatility and can complete rail grinding. Comprehensive grinding is beneficial for maintenance, but in the daily maintenance of rails, it cannot realize the intelligentization of rail maintenance. In the grinding of rails, the degree of wear on the top surface of the rails is different. If the same grinding force is used, It will make the rail surface with low wear degree suffer more grinding, resulting in waste of materials, and it will also prevent the rail surface with high wear degree from being fully polished, so that the repair can meet the smoothness standard of the rail surface, which will lead to rail repair after rail repair. Surface accuracy is not high
