A parallel intelligent grinding robot arm for high-speed railway tracks

Abstract

The invention relates to an intelligent grinding mechanical arm for a railway special for parallel high-speed trains. The intelligent grinding mechanical arm comprises a parallel supporting mechanism, wherein the parallel supporting mechanism comprises a fixed platform; three parallel supporting chains are uniformly mounted on the lower end surface of the fixed platform along the axial direction; the top ends of the three parallel supporting chains are mounted on a movable platform; four hydraulic cylinders IV are symmetrically mounted at the lower end of the movable platform; adjustable grinding devices are mounted at the top ends of the four hydraulic cylinders IV; the four hydraulic cylinders IV can adjust the grinding height of the intelligent grinding mechanical arm, so that the intelligent grinding mechanical arm can be applied to the grinding operation of railways at different terrain heights; and the adjustable grinding devices can be completely and closely fitted to the surface of the railway for grinding back and forth, and are large in grinding range, good in grinding effect and high in working efficiency. The intelligent grinding mechanical arm can realize a full-automatic grinding function for the railway, does not need manual operation, and is high in automation degree; shakes of equipment in a working process are eliminated, and the equipment is high in stability.

Description

technical field [0001] The invention relates to the technical field of rail processing, in particular to a parallel-connected high-speed rail special track intelligent grinding mechanical arm. 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...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a parallel-connected high-speed rail special track intelligent grinding mechanical arm, which can solve the problems of manual operation, low degree of automation, slow grinding speed, and equipment working process in the existing rail grinding equipment. There are problems such as vibration, poor stability of equipment, uneven grinding force, poor grinding effect, difficulty in fully attaching the equipment to the surface of the rail, small grinding range, small application range, and low work efficiency. The automatic grinding function of rails can be realized. , no need for manual operation, high degree of automation, eliminating the vibration during the working process of the equipment, good stability of the equipment, and has the advantages of fast grinding speed, equipment can be completely attached to the surface of the rail, large grinding range, wide application range and high work efficiency.
