Obviously, the two cannot meet the needs of my country's high-speed rail grinding
[0003] On-line rail grinding is a typical area grinding, which should be completed by a flexible abrasive belt, but the traditional abrasive belt can only be used under low-speed and low-pressure conditions, and cannot meet the requirements of high speed and large grinding volume

Embodiment Construction

[0022] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] The invention provides a grinding wheel capable of array surface area polishing, which includes a grinding wheel main body, which is a rigid rotating wheel.

[0024] The middle part of the grinding wheel body is provided with one or several air storage cavities for storing compressed air; the grinding wheel body is provided with one or several small air compressors, and the air outlet of the small air compressors is connected with the air storage cavity. The opening and closing and speed regulation of the air compressor are controlled by the remote control device. The main body of the grinding wheel is provided with a high-pressure blower for delivering high-pressure and high-speed airflow to the airflow cooling channel, and the airflow cooling channel includes the first airflow cooling channel, the second airflow cooling channel, and the thir...

Abstract

The invention provides a grinding wheel with an array-type region grinding function. The grinding wheel comprises a grinding wheel body. One or more sliding rigid or semirigid abrasive blocks are arranged on the circumference of the edge of the grinding wheel body. The abrasive blocks slide in the radial direction of the grinding wheel body. Through the structure, the grinding wheel with the array-type region grinding function can always maintain balanced grinding pressure on a ground region as a traditional grinding belt do. When the shaft array interval radian is small, and the telescopic travel of a polishing and grinding module is increased, the multiple abrasive blocks can simultaneously act within a certain region range, and the grinding balance is maintained in a large range. The working linear speed can reach hundreds of meters per second or over, rapid cooling can be achieved, and the service life is long.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to a grinding wheel capable of array surface polishing. Background technique [0002] For the on-line grinding of rails, the combined grinding method of zirconium corundum grinding wheels imported from the United States is currently used on a large scale. This method is to place 48 pieces of zirconium corundum resin-bonded grinding wheels on three locomotives to grind the rails simultaneously from different directions. The fastest grinding speed is only 18 kilometers per hour, and the dust spreads everywhere, directly polluting electrical equipment along the road. The latest grinding locomotive imported from Europe has a working speed of only 30 kilometers per hour. When working, the entire railway line is closed. Obviously, these two cannot meet the needs of my country's high-speed rail grinding. [0003] On-line rail grinding is a typical surface area grinding, which should be done by a flexi...
