Abstract

The invention provides a rotary repair method of a locomotive comprehensive test bed. The method comprises the following steps of positioning, clearance adjustment, size detection, rotary repair and size reinspection. Synchronous or sequential online rotary repair to track wheels and wheel pairs is achieved through a rotary repair system integrally arranged with the track wheels and the wheel pairs, and the rotary repair efficiency is improved. A positioning assembly is used for positioning a vehicle body, it is guaranteed that the axes of the wheel pairs and the track wheels are kept in the same vertical plane in the rotary repair process, and friction contact transmission is achieved. The technical problem of low rotary precision caused by displacement of bogies or track wheel units in the rotary repair process is reduced.

Description

technical field [0001] The invention relates to the technical field of rail vehicle maintenance, in particular to a method for repairing a rolling stock comprehensive test bench. 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 driving mechanism, a control mechanism, an out-of-roundness measu...
