Railway turnout repair device and rail burr repair method

Abstract

The invention discloses a railway turnout repair device and repair method. The device comprises a grinding mechanism and a walking frame. The grinding mechanism comprises a base, an adjustable machine frame and an abrasive belt driving mechanism. The base is fixedly connected with the walking frame, the adjustable machine frame is movably connected to the base through an adjusting driving mechanism, and the abrasive belt driving mechanism is arranged on the adjustable machine frame; the abrasive belt driving mechanism comprises a driving wheel, a tension wheel and a bottom wheel, an abrasive belt sequentially makes contact with and passes by the driving wheel, the tension wheel and the bottom wheel, the abrasive belt is driven by the driving wheel to rotate, a profiling pressing block is arranged on the inner ring of the abrasive belt below the adjustable machine frame, and the profiling face of the profiling pressing block is in sliding connection with the inner surface of the abrasive belt. The adjustable machine frame horizontally moves so as to make the profiling pressing block press the abrasive belt so that the abrasive belt can be in sliding connection with the side face of a rail, burrs of the rail can be ground in all directions, the whole device is high in automation degree, manpower is greatly saved, grinding efficiency and the grinding effect are improved, stability is good, manufacturing cost is low, and the device and method are suitable for large-scale application and popularization in industry.

Description

technical field [0001] The invention relates to the technical field of railway rail repair, in particular to a railway switch repair device. Background technique [0002] Turnouts are an important part of railway rails. After long-term use, burrs will occur on the side of the rail surface, which will affect the normal and safe use of the track. The grinding of turnouts has become an important part of railway maintenance operations. After years of experience, railway experts generally It is agreed that rail grinding has the following advantages: prolonging the life of the rail track, prolonging the track processing cycle, improving the running stability of the vehicle, and reducing noise. However, due to the complex situation of railway turnouts (changing lines, various rail shapes, narrow space, etc.), the existing equipment has huge limitations: the cost of the turnout grinding locomotive or the grinding robot is extremely high, and the existing common grinding wheel Typ...

Problems solved by technology

However, due to the complex situation of railway turnouts (changing lines, various rail shapes, narrow space, etc.), the existing equipment has huge limitations: the cost of the turnout grinding locomotive or the grinding robot is extremely high, and the existing common grinding wheel Type turnout grinding equipment adopts the grinding wheel grinding method, which requires manual adjustment of the contact position of the grinding wheel, the grinding effect is heavily dependent on the operator, the grinding speed is slow, and the effect varies from person to person, which is very unstable
