Problems solved by technology
In the traditional welding seam grinding operation, grinding wheel grinding machines are often used for grinding rail welds. Due to the rigid contact between the grinding wheel and the rail, the impact on the rail is large, the vibration is large, and the grinding quality is easily affected; the contact area between the grinding wheel and the weld is small, and the grinding wheel wears quickly. , the height of the grinding wheel needs to be constantly adjusted during the grinding process; at the same time, the grinding wheel needs to rely on the envelope of a small straight line to approach the target profile curve of the rail, which results in low grinding efficiency and high labor intensity for the operator

The invention provides a profiling abrasive belt grinding machine for a steel rail. The profiling abrasive belt grinding machine for the steel rail mainly comprises a rack, an abrasive belt, a drive wheel, a contact wheel, travelling wheels and an internal combustion engine, wherein the abrasive belt is sequentially wound on the excircles of the drive wheel and the contact wheel; the travelling wheels are installed at support positions at the two sides of the lower end of the rack, and travel along the steel rail; the internal combustion engine is located above the rack, and is connected with the drive wheel through a belt; and a tensioning mechanism is arranged between the drive wheel and the contact wheel. According to the profiling abrasive belt grinding machine for the steel rail, which is provided by the invention, the abrasive belt is used as a grinding tool, and the abrasive belt and the steel rail form flexible contact during grinding operation due to the own characteristics of a rubber layer in the contact wheel, and the abrasive belt, thus the influence of vibration of the grinding machine on the grinding quality can be reduced; a tensioning device is installed between the drive wheel and the contact wheel, thus the overall structure is simplified; and only the contact wheel moves up and down during grinding pressing, thus the operation is convenient.
Description
technical field [0001] The invention relates to the technical field of railway maintenance machinery, in particular to a rail profiling abrasive belt grinder. Background technique [0002] After on-line welding and repairing of railway rails, the welds need to be polished to make the surface of the rails smooth. In the traditional welding seam grinding operation, grinding wheel grinding machines are often used for grinding rail welds. Due to the rigid contact between the grinding wheel and the rail, the impact on the rail is large, the vibration is large, and the grinding quality is easily affected; the contact area between the grinding wheel and the weld is small, and the grinding wheel wears quickly. , the height of the grinding wheel needs to be adjusted continuously during the grinding process; at the same time, the grinding wheel grinding needs to rely on the envelope of a small straight line to approach the target profile curve of the rail, the grinding efficiency is l...
