Background

The pneumatic monorail crane uses an I-steel suspended above a roadway as a track and comprises transport equipment such as a tractor, a brake car, a carrier car and the like. The tractor generally adopts the reduction gear to provide power, and including two sets of reduction gears setting up in the both sides of track respectively, current tractor structure is as shown in the chinese patent of patent publication No. CN211468421U (a pneumatic monorail hoist variable speed adjusting device), and unilateral speed reduction includes an input shaft, and the input shaft drives two output shafts rotation respectively, and output shaft top fixedly connected with gyro wheel. The rollers are symmetrically arranged on two sides of the rail respectively, and the symmetrical rollers clamp the rail web plate. When the monorail crane is towed, the rollers rotate to generate friction with the track web, so that the monorail crane moves along the track to provide power for other components. However, the existing tractors have limited traction force, so that the carried goods are limited, and the goods transportation efficiency is low. Aiming at the problems in the prior art, we propose a unilateral triaxial output speed reducer.
