A rail grinding device adaptable to rails with different distances

Abstract

The invention discloses a rail grinding device capable of adapting to rails with different distances. The device comprises a machine body. A left-right sliding cavity with an upward opening is formedin the machine body. A left-right sliding rail is arranged on the lower wall of the left-right sliding cavity. A left-right slide block is arranged in the left-right sliding rail. A sliding block spring is fixedly arranged on the outer surface of the left side of the left-right sliding block. A switching cavity is formed below the left-right sliding cavity. A through hole for arranging a clampingposition is formed in the upper part of the left-right sliding cavity. A transmission cavity is formed in the right side of the switching cavity. A rotatable second rotating rod is arranged in the transmission cavity. A locking cavity is formed in the right side of the transmission cavity. The second rotating rod extends left and right into the switching cavity and the locking cavity. A brake clamping ring for locking is arranged in the locking cavity. After the distance between grinding knives is adjusted, the position between the grinding knives can be locked, and therefore, the situation inwhich the grinding quality is affected due to the fact that the distance between the grinding knives is changed due to vibration or other reasons in the grinding process is avoided.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to a rail grinding device that can adapt to rails with different distances. 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; The remaining welding points 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 also produce rust spots, which reduces the smoothness of the rails; 4. The rails are exposed to the outside for...

[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; The remaining welding points 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 also produce rust spots, which reduces the smoothness of the rails; 4. The rails are exposed to the outside for a long time. There is a lot of dust attached to the surface, which reduces the smoothness of the rails. The existing rail grinding devices are often used for grinding rails of a single specification, and are often not suitable for rails of different specifications due to geographical terrain and other reasons.
