Problems solved by technology
Traditionally, grinding wheel grinding machines are mostly used to eliminate corrugation. The grinding wheel is in rigid contact with the rail, and the vibration is large; the contact area between the grinding wheel and the weld is small, and the grinding wheel wears quickly. Therefore, the height of the grinding wheel must be adjusted continuously during the grinding process, and the operator is labor-intensive. Now The grinding machine with rail corrugated grinding wheel needs to install rollers on both sides to assist to complete, the size is large, and it is not easy to operate

The invention provides a rail corrugation abrasive belt grinder. The rail corrugation abrasive belt grinder comprises an abrasive belt, a driving wheel, a tensioning wheel, a parallel-arranging contact wheel, a rack, a support, walking wheels, an internal combustion engine and a lifting pressure applying device. The abrasive belt is wound on the outer circles of the driving wheel, the tensioning wheel and the parallel-arranging contact wheel on the support sequentially. The support is connected with the internal combustion engine through the lifting pressure applying device. The walking wheels are installed in the support positions at the lower end of the rack and walk along a rail. According to the rail corrugation abrasive belt grinder, the abrasive belt is adopted as a grinding tool, through a rubber layer of the contact wheel and the characteristics of the abrasive belt, the abrasive belt makes flexible contact with the rail during grinding operation, and the influence of vibration of the grinder on the grinding quality can be lowered. According to deflection of a grinding mechanism, precise locating of a grinding angle is completed through an angular deflection disc and a locating pin. The inwards-concave type parallel-arranging contact wheel is adopted as the contact wheel, so that the rail corrugation grinding efficiency is improved effectively.
Description
technical field [0001] The invention relates to the technical field of railway maintenance machinery and equipment, in particular to a rail wave abrasive belt grinder. Background technique [0002] Long-term operation of railway rails is prone to corrugation, which affects the stability and comfort of train operation. Therefore, grinding is required to make the surface of the rails smooth. Traditionally, grinding wheel grinding machines are mostly used to eliminate corrugation. The grinding wheel is in rigid contact with the rail, and the vibration is large; the contact area between the grinding wheel and the weld is small, and the grinding wheel wears quickly. Therefore, the height of the grinding wheel must be adjusted continuously during the grinding process, and the operator is labor-intensive. Now The grinding machine with rail corrugated grinding wheel needs to install rollers on both sides to assist to complete it. The size is large and it is not easy to operate. Co...
