Portable foldable shear type lifter

Abstract

The invention discloses a portable foldable shear type lifter. The portable foldable shear type lifter comprises bases, transitional plates, first shear arms, second shear arms and worktables. At least two hydraulic cylinders are fixed on the bases; the transitional plates are fixed on the end sides of telescopic rods of the hydraulic cylinders; the first connecting ends of the first shear arms are connected to the bases; the second connecting ends of the first shear arms are connected to the transition plates; the third connecting ends of the second shear arms are connected to the transitional plates; and the fourth connecting ends of the second shear arms are connected to the worktables. By designing a moving scheme of the shear type lifter, two ends of the first shear arms and the second shear arms are correspondingly hinged together according to the characteristics of parallelogram. The whole set of device is powered by a hydraulic system and the strokes of the pistons are changed to lift the lifter, so that the problems that an existing shear type lifter is slow in lifting speed, relatively large in stress of the hydraulic cylinders at the beginning of work, inconvenient to carry and poor in safety performance are solved.

Description

technical field [0001] The invention belongs to the technical field of lifts, in particular to a portable and foldable scissor lift. Background technique [0002] The structure of the hydraulic car lift is mainly divided into three categories: pneumatic, hydraulic and mechanical from the drive type of the lift. Among them, hydraulic pressure is the most, followed by mechanical type, and pneumatic is the least; from the column structure, there are mainly single-column, double-column, four-column, scissors and trench lifts. Hydraulic lifts are characterized by stability, low noise, high strength, long service life, and low maintenance costs. Hydraulic lifts generally consist of hydraulic motors, jacking cylinders and columns, sliding brackets, balance chains, and electrical control systems. It consists of several parts. Since the weight of the car is generally large, coupled with the weight of the lifting device itself, the lifting force is required to be large, and the lifti...

Problems solved by technology

[0004] The purpose of the present invention is to provide a portable foldable scissor lift. By designing the motion scheme of the single scissor lift, the whole set of equipment is powered by a hydraulic system to change the stroke of the piston rod, thereby solving the current Scissor lifts have problems of slow lifting speed, large force on the hydraulic cylinder at the beginning of work, inconvenient carrying, and poor safety performance
