2. Application range
The machine is mainly used for grinding rail thermite seamless welding or strengthening welding and burr caused by rail wear. The machine body is made of high-strength aluminum alloy frame, equipped with inclined anti-skid guide wheel, which can grind both sides and top surface of rail head. It is a special equipment for rail head grinding in railway engineering.
B. Basic structure & Working principle
1. Basic structure: As shown in the figure, the machine is composed of armrest, grinding head, adjusting mechanism, sill, profiling wheel and gasoline engine.
2. Working principle: The engine drives the small pulley to rotate, and the grinding head rotates through the belt drive, which will produce grinding effect on the rail; The grinding position is adjusted by rotating the handwheel to control the lifting and lowering of the lifting lever; The position of the grinder is positioned by the elastic top force between the handlebar and the bottom beam, and the grinding can be realized while the handrail is inclined.
