Abstract

The invention discloses a high-pressure water jet steel rail grinding system which comprises a vehicle body assembly arranged on a rail, a front power bogie and a rear power bogie. The vehicle body assembly is provided with a traction system, a pressurization system, a detection system, a cleaning system, a grinding material supply system, a grinding system and an electrical control system. The traction system, the pressurization system, the grinding system, the abrasive supply system and the electrical control system are all arranged in the middle of the vehicle body assembly. The grinding material supply system comprises a grinding material barrel, a grinding material pipeline and an electric control transposition valve which are arranged above the grinding system; the invention further discloses a corresponding polishing efficiency optimization control method. High-strength rough grinding is adopted in the early stage and used for treating obvious corrugation, fat edges and the like; high-precision fine grinding is adopted in the later stage, and the grinding efficiency is optimized; insufficient polishing or excessive polishing is avoided, and multi-degree-of-freedom polishing posture adjustment is independently achieved; the polishing efficiency is optimized, self-adaptive and intelligent polishing operation is achieved, and the polishing efficiency is further optimized.

Description

technical field [0001] This patent relates to the field of rail grinding, in particular to a high-pressure water jet rail grinding system and a method for optimizing the grinding efficiency thereof. Background technique [0002] With the accumulation of operating mileage, the steel rail, as the load-bearing component of the wheel-rail relationship, bears various complex and changeable loads, impacts and frictions from the vehicle, resulting in damage and defects such as corrugation, cracks, peeling, and fat edges on the surface and inside of the rail. , seriously affecting the driving stability and safety. As we all know, rail grinding is currently the most effective measure to eliminate rail surface failures. In order to remove the disease, repair the profile, prolong the life of the rail, and improve the wheel-rail relationship, rail grinding and repairing is widely used at home and abroad as the main means of comprehensive maintenance of the railway system. The rail gri...
