Abstract

The invention provides rail wheel and bogie wheel repairing equipment of a high-speed rail bearing comprehensive test bed. The equipment comprises a vehicle body, positioning assemblies and bogies and further comprises a rail wheel system correspondingly arranged under the bogies and a turning repair system which is used for sequentially adjusting the clearance of corresponding wheel pairs on the bogies and rail wheels on the rail wheel system and respectively repairing the wheel pairs and the rail wheels. Wheel pair shafts and rail wheel shafts are used as rotating bodies for turning repair, centering turning repair is adopted, and the technical problem that the center of the wheel pairs or rail wheels cannot be determined in a non-wheel-falling turning repair mode in the prior art is solved; and a turning repair assembly arranged on the rack is used for turning repair of the wheel pairs or the rail wheels, the structure is compact, the machining precision is high, synchronous turning repair can be conducted on the wheel pairs and the rail wheels at the same time, synchronous turning repair is conducted on the set of rail wheels and the wheel pairs with the similar abrasion degree, the stability of the turning repair process is guaranteed, and then the turning repair precision is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle maintenance, in particular to equipment and methods for repairing rail wheels and bogie wheels of a comprehensive test bench for high-speed rail bearings. Background technique [0002] After the existing locomotive and vehicle rolling test bench works for a long time, its track wheel tread wears, and the track wheel tread wears to a certain extent and needs to be repaired to restore the original tread shape curve. [0003] In the existing technical solution, the vehicle repair is carried out by disassembling the rail wheel and the wheel set, which has disadvantages such as reinstallation after the repair is completed, complicated process path, difficult disassembly, long maintenance time, and high cost. [0004] Chinese invention patent CN 111318724 A discloses a wheel turning repairing equipment and method thereof. The wheel turning equipment includes a tool holder, a driving wheel, a drivi...
