Abstract:

To solve the problem of wheel skidding in a few working platform hoist bogies，by analyzing the structural form and installation form of the hoist, it is judged that the wheel skidding is caused by excessive wheel pairs, lack of selfadjusting function, poor contact between the wheel tread and the track, resulting in insufficient wheel pressure. Aiming at the wheel skidding problem of individual trolley hoist when it is running, a set of auxiliary running mechanism of platform hoist is designed. By adding a ring gear to the drive wheel device and adding a rack beside the track, the problem of wheel skidding when the trolley hoist is running is solved.

Key words:

platform hoist；bogie wheel, skidding, auxiliary running mechanism
