Abstract

The invention discloses a straight jacking type freight lifting platform and relates to the technical field of freight lifting devices. The straight jacking type freight lifting platform comprises a frame body, a hydraulic cylinder arranged on the lower portion of the frame body and a freight lifting platform body dragged by a steel wire rope pulley winding set driven by the hydraulic cylinder. A push rod driven by a fall-preventing cylinder is arranged on the upper portion of the frame body. The push rod transversely extends out at working time. Compared with the prior art, the straight jacking type freight lifting platform overcomes the defect of rebounded height, caused by hydraulic compression, of the platform body, and is increased in safety performance and reliability.

Description

technical field [0001] The invention relates to the technical field of cargo lifting devices, in particular to a straight-top cargo lifting platform. Background technique [0002] At present, the structure of most hydraulic straight-top cargo platforms is composed of hydraulic cylinders, wire rope pulley windings, cargo platforms and skeletons. Place the goods on the loading platform, start the hydraulic system to drive the platform up, amplify the lifting height through the pulley winding, stop unloading when the goods reach the height of the predetermined top dead center, and then return to the bottom dead center. Generally, the hydraulic cargo platform cannot limit the rebound height of the platform due to hydraulic compression after unloading, which may easily cause cargo or even personal accidents. It is much heavier, and when the hydraulic system leaks or the wire rope breaks, the goods and the platform are prone to fall at an extremely fast speed and cause accidents....
