Title:
STEEL RAIL GRINDING EQUIPMENT BASED ON HIGH-PRESSURE WATER JET TECHNOLOGY, AND OPERATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/000992
Kind Code:
A1
Abstract:
Disclosed is steel rail grinding equipment based on high-pressure water jet technology, comprising a flatbed vehicle (1), a water jet grinding unit (2) provided inside the flatbed vehicle (1), a rail measurement unit (5), a grinding control terminal (6), and a hydraulic driving device (9). The hydraulic driving device (9) comprises a speed sensor (911) and a position sensor (912); the water jet grinding unit (2) comprises a lifting/lowering mechanism (21) connected to the flatbed vehicle (1), grinding water jet cutters (22) connected to the lifting/lowering mechanism (21), and a water flow pressure regulating device (23) and an abrasive feeding device (24) separately communicated with the grinding water jet cutters (22). According to the present invention, a central controller controls the flatbed vehicle to move to a grinding operation coordinate point in real time, and according to different positions, different angles, different corrugations, and different profiles of steel rails, the water jet grinding unit performs automatic position and attitude regulation along the arc of a mounting base for grinding.
