Scissor type lift and lifting device thereof

Abstract

The invention discloses a scissor type lift and a lifting device thereof. The lifting device comprises a protective supporting plate, a lock, a bumper, a head shaft and at least two parallel engine-driven telescopic devices, wherein each engine-driven telescopic device comprises a telescopic rod at one end thereof respectively; the head shaft is pivoted with tail ends of telescopic rods of the at least two parallel engine-driven telescopic devices respectively; the two ends of the protective supporting plate are fixed to the at least two parallel engine-driven telescopic devices respectively; the lock is arranged on the protective supporting plate between the two engine-driven telescopic devices; one end of the bumper is pivoted with the head shaft; the rod is close to the lock and is provided with a plurality of notches distributed along the axial direction; and the notches and the lock forms a self-locked structure locked in one way. The scissor type lift and the lifting device thereof of the invention can ensure the safety of the lifting operation, reduce the height difference between two platforms of the scissor type lift and meet the standard requirement.

Description

technical field [0001] The invention relates to a load-bearing machine, in particular to a scissor lift and a lifting device thereof. Background technique [0002] The function of the car lift is to lift the car from the ground to a certain height, which is convenient for the maintenance personnel to detect and repair the car. According to the structure of the lift, the lift can be divided into three categories: 1) two-post lift; 2) four-post lift; 3) scissor lift. [0003] In order to avoid the loss of human property caused by the sudden fall of the car, it is necessary to design a safety device with high safety. Among them, the mechanical insurance is the main safety guarantee device during the use of the car scissor lift. When personnel perform vehicle maintenance, mechanical insurance needs to ensure that the height difference between the left and right working platforms of the scissor lift is within the permitted range and the safety of the vehicle maintenance personn...

Problems solved by technology

Usually the total length of the bottom plate parts 1 and 4 is 2 meters or more, and the mechanical structure of this length can only be welded and positioned by the above-mentioned welding technology, that is, this technology will inevitably cause thermal deformation and deformation of the mechanical structure after welding.
