Abstract

The invention provides an aerial work platform and an autorail. The aerial work platform comprises a slewing mechanism, a base, a telescopic arm, a folding arm, a drive cylinder and a working bucket. The slewing mechanism comprises a support seat, a slewing seat and a drive device. The drive device comprises a hydraulic cylinder and a slewing bearing. The base is fixed on the slewing seat. A lower leveling cylinder is disposed between a fixed arm and the base. An upper leveling cylinder is disposed between a sliding arm and the folding arm. A first sprocket is hinged to the hinge joint of the folding arm with the sliding arm. The other end of the upper leveling cylinder is hinged with the edge of the first sprocket. A second sprocket is hinged to the hinge joint of the folding arm with the working bucket. The second sprocket is fixed on the working bucket. A chain is disposed between the first sprocket and the second sprocket. The distance between the fixed arm and the hinge joint of the lower leveling cylinder with the base equals to that between the first sprocket and the hinge joint of the upper leveling cylinder with the sliding arm. Reliability of the aerial work platform is improved.

Description

technical field [0001] The invention relates to a dual-purpose vehicle for railway and highway, in particular to an aerial work platform and a dual-purpose vehicle for railway and highway. Background technique [0002] At present, the dual-purpose vehicle for railway and highway is widely used in the rail transportation industry because it can run on both the road and the railway. The dual-purpose vehicle for railway and highway is usually used for operations such as railway traction, emergency repair, construction and emergency rescue.
