Trolley for overhauling sorting machine

The trolley can linearly move in the direction of a track at the upper end of the sorting machine and comprises an operation platform, supports are arranged on the periphery of the operation platform, and a sliding assembly is arranged at the end of the operation platform. The sliding assembly comprises a base connected to the working platform and rolling wheels arranged on the base, and the rolling wheels are movably connected to the base and can drive the working platform to move linearly; the operation platform further comprises a braking assembly arranged on the support, the braking assembly has an abutting state or a separating state relative to the idler wheels, and when the braking assembly abuts against the idler wheels, the operation platform stops moving. When the brake assembly is separated from the rolling wheels, the operation platform can linearly move on the track of the sorting machine, so that personnel can quickly maintain components on the sorting machine. 本实用新型公开了一种用于分选机检修的小车，能够沿着分选机上端的轨道方
