specific Embodiment approach

[0014] Rail grinding car of the present invention, its preferred embodiment is:

[0015] It includes a frame body, a grinding unit is arranged on the frame body, a running wheel is arranged on the lower part of the frame body, the frame body is suspended on a grinding train, and the distance between the frame body and the grinding train is There is a lifting hydraulic cylinder between them.

[0016] A locking device is provided between the frame body and the grinding train.

[0017] A traction device is provided between the frame body and the grinding train, one end of the traction device is hinged to the grinding train, and the other end is hinged to the frame body.

[0018] The rail grinding vehicle is a rail profile grinding vehicle or a corrugated grinding vehicle.

[0019] The rail profile grinding vehicle includes four groups of grinding units, and each group of grinding units includes two grinding heads.

[0020] The corrugation grinding vehicle includes two groups o...

specific Embodiment

[0021] Such as figure 1 As shown, it includes a welded frame (frame body), four lifting hydraulic cylinders for controlling the lifting of the trolley, a locking device, a traction device, and a deflectable grinding unit. The frame body features four rimmed wheels that ride on rails while sanding. The traction device realizes two-way traction operation through a tow bar.

[0022] During the grinding operation, the grinding motor of the grinding unit is lifted, the locking device is unlocked, the trolley falls into the rail surface under its own weight, the deflection angle of the grinding unit is set, and the motor drives the grinding wheel to grind the rail surface.

[0023] The rail grinding car includes a rail profile grinding trolley and a wave grinding trolley. The main difference is that the grinding units are different. The rail profile grinding trolley has four sets of grinding units, while the corrugation grinding trolley has two sets of grinding units. The other par...

Abstract

The invention discloses a steel rail polishing vehicle which comprises a vehicle frame. Polishing units are arranged on the vehicle frame, traveling wheels are arranged on the lower portion of the vehicle frame, the vehicle frame is suspended on a polishing train, and a lifting hydraulic cylinder is arranged between the vehicle frame and the polishing train. Locking devices are arranged between the vehicle frame and the polishing train. A traction apparatus is arranged between the vehicle frame and the polishing train. The steel rail polishing vehicle has the advantages that wavy abrasion of tracks and scratching of wheel rails can be amended by the steel rail polishing vehicle, tilting deformation of inner and outer rails can be corrected by the steel rail polishing vehicle, contact surfaces and the like of the wheel rails can be trimmed, accordingly, the defects can be overcome by the steel rail polishing vehicle, and the steel rail polishing vehicle is applicable to polishing straight and curved steel rails for large road maintenance operation.

Description

technical field [0001] The invention relates to a rail repair device, in particular to a rail grinding vehicle. Background technique [0002] In the 1950s, with the rapid economic development of various countries, the volume and speed of railway transportation developed rapidly. Subsequently, the damages such as wavy wear and contact fatigue of rails are becoming more and more serious, which affects the safety and economy of railway transportation. The maintenance and repair of rails is becoming more and more important, and rail grinding vehicles have appeared to grind and polish the rails. [0003] In the prior art, there are two types of rail profile grinding trolleys and corrugated grinding trolleys according to the wear and tear of rail contours, which can perform preventive and restorative grinding on the rails on the line during operation and operation, and eliminate the wavy wear of the rails and the fat edge of the rails. , saddle wear, weld sag and fish scale crac...
