Rail grinding device

Abstract

The invention discloses a rail grinding device which comprises a moving platform. The moving platform reciprocates along the two sides of a rail, the moving platform is provided with a first linear lifting assembly, and the first linear lifting assembly is arranged towards the top surface of the rail; the first linear lifting assembly is provided with a rotating part and a rotating platform, the rotating part drives the rotating platform to rotate, the rotating platform is provided with a second linear lifting assembly, and the second linear lifting assembly is provided with a power part; and the power part is connected with a grinding head or connected to the grinding head through by a power steering gear. According to the rail grinding device, different angles and different faces of the rail can be ground and maintained by using a single unit, and the use range is wide and versatility is high.

Description

technical field [0001] The invention relates to the field of rail grinding and maintenance, in particular to a rail grinding device. Background technique [0002] In recent years, with the continuous development of my country's railway transportation industry, the train weight and traffic density of main trunk lines have been increasing, and large-scale passenger dedicated lines have been continuously constructed. Improving the comfort and safety of railway operation is the basic requirement in the process of railway development. However, due to my country's high traffic density, increased passenger speed, heavy freight, and harsh driving conditions, trains seriously damage the track structure, and the rail surface is prone to defects such as fatigue cracks, spalling, fat edges, etc., and wave wear, which affect the safety and stability of railway operation. Sex has a serious impact. [0003] Nowadays, when grinding and repairing rails, manual grinding machines or rail grind...

However, due to my country's high traffic density, increased passenger speed, heavy freight, and harsh driving conditions, trains seriously damage the track structure, and the rail surface is prone to defects such as fatigue cracks, spalling, fat edges, etc., and wave wear, which affect the safety and stability of railway operation. sex has a serious impact

[0003] Nowadays, when grinding and repairing rails, manual grinding machines or rail grinding vehicles are generally used for operation. The traditional manual grinding machines are light in structure, but the grinding accuracy is not high, the grinding efficiency is low, the operation is complicated, and the labor intensity is high. The rail grinding vehicle Although the grinding speed is fast, the precision is high, and the effect is good, but because there are many rail grinding surfaces, different grinding surfaces need to use different grinding units to achieve rail grinding, which has poor versatility and is difficult to repair and maintain.
