Problems solved by technology
These small grinding machines all use the grinding wheel as the grinding tool, and there is a rigid contact between the grinding wheel and the rail. Any vibration of the grinding machine will directly affect the grinding quality of the rail. The target profile curve has low grinding efficiency and high labor intensity for the operator, making it difficult to meet the high-precision and high-efficiency maintenance requirements of existing railways, especially high-speed railway turnouts

The invention provides a steel rail turnout abrasive belt grinding machine which comprises a machine frame, traveling wheels, a gasoline engine, a triangular belt, an abrasive belt grinding head device, a horizontal transverse moving device, an angle deflection mechanism and a lifting pressure applying mechanism. The abrasive belt grinding head device comprises an abrasive belt, a contact (driving) wheel, a guiding wheel, a tensioning mechanism and an abrasive belt grinding head installation base plate. The abrasive belt is sequentially wound on the outer circle of the contact (driving) wheel, the outer circle of the guiding wheel and the outer circle of a tensioning wheel. According to the steel rail turnout abrasive belt grinding machine, the abrasive belt serves as a grinding tool to grind a steel rail turnout, through a rubber layer of the contact wheel and the characteristics of the abrasive belt, the abrasive belt is in flexible contact with a steel rail during grinding operation, and the influences of vibration of the grinding machine on the grinding quality can be reduced; and the grinding operation requirements for the whole contour of the steel rail can be met with a enveloping frequency, and the grinding operation efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of railway maintenance machinery, in particular to an abrasive belt grinder for steel track switches. Background technique [0002] The turnout is an important line connection equipment for rolling stock to transfer from one track to another. Due to the long-term high-load rolling of the locomotive wheels, it is prone to various damages such as corrugation, fat edges, cracks, and falling blocks, which seriously affects The locomotive runs safely. The structure of railway turnout is complicated, there are many restrictions and constraints, and the maintenance is very difficult. At present, various railway engineering departments usually use small-scale steel track switch grinding machines to assist large and medium-sized steel rail grinding vehicles to realize the maintenance and repair of various steel rails (such as point rails, core rails, guard rails, wing rails, etc.) in the turnout area. These small g...
