Lifting platform supporting leg

Abstract

A lifting platform supporting leg comprises a fixed supporting leg body, a movable supporting leg body, a hydraulic cylinder and a supporting foot. One end of the fixed supporting leg body is fixed to a bottom frame of a lifting platform, and the other end of the fixed supporting leg body is hinged to the upper end of the movable supporting leg body. The tail end of the hydraulic cylinder is hinged to the fixed supporting leg body. Two guide grooves are oppositely formed in the two sides of the movable supporting leg body. The front end of a piston rod of the hydraulic cylinder is provided with a transverse shaft. The two ends of the transverse shaft are located in the guide grooves in the two sides of the movable supporting leg body respectively. The supporting foot is connected to the lower end of the movable supporting leg body through a universal joint. By means of the lifting platform supporting leg, the problems that cost is increased and occupied space is enlarged by the adoption of a long-stroke hydraulic cylinder are solved; the supporting foot can rotate according to the inclination angle of the ground so as to make stable contact with the inclined surface, and therefore safety accidents caused by instability of the lifting platform are avoided; meanwhile, the supporting foot is connected to the bottom end of the supporting leg through a pin, and therefore the supporting foot with antiskid teeth can be replaced as required.

Description

technical field [0001] The invention relates to an auxiliary device used on a lifting platform, in particular to a supporting leg of the lifting platform. Background technique [0002] Lifting platform is a multi-functional lifting and loading and unloading mechanical equipment, which makes high-altitude operations more efficient and safer. At present, the lifting platform is divided into fixed type and mobile type. When in use, it is often encountered on a slope or a slope. The supporting legs of the ordinary lifting platform support legs can only completely contact the ground on the horizontal plane. It cannot be implemented, which will cause the instability of the lifting platform, which may slide and cause safety accidents. Moreover, in order to ensure that the bottom of the movable legs of the lifting platform can fall to the ground, hydraulic cylinders with long strokes are used between the supporting legs of the lifting platform, which not only has high cost, but al...

Problems solved by technology

At present, the lifting platform is divided into fixed type and mobile type. When in use, it is often encountered on a slope or a slope. The supporting legs of the ordinary lifting platform support legs can only completely contact the ground on the horizontal plane. It cannot be implemented, which will cause the instability of the lifting platform, which may slide and cause safety accidents.

Moreover, in order to ensure that the bottom of the movable legs of the lifting platform can fall to the ground, hydraulic cylinders with long strokes are used between the supporting legs of the lifting platform, which not only costs high, but also takes up a lot of space
