Trolley transmission mechanism with balance wheel unit

The utility model relates to a trolley transmission mechanism with a balance wheel unit, and belongs to the technical field of metallurgy. Comprising a trolley frame, a plurality of balance wheel mechanisms arranged at intervals are arranged at the bottom of the trolley frame in the length direction, the balance wheel mechanisms are fixed to the trolley frame, any balance wheel mechanism is connected with a driving device, and the driving device drives the balance wheel mechanisms to rotate and drives the trolley frame to move. Each balance wheel mechanism comprises two balance wheel units which are symmetrically arranged in the width direction of the trolley frame. The two balance wheel units are connected through a transmission shaft. Each balance wheel unit comprises a balance wheel frame, the balance wheel frames are fixed to the trolley frame through balance pins, and a plurality of balance wheels arranged at intervals are arranged in the balance wheel frames. Damage faults of the balance wheels are redu
