Four-column lifter with pressed locking lifting car

Abstract

The invention relates to a four-column lifter with a pressed locking lifting car. The four-column lifter comprises four stand columns distributed in a rectangular form; a left side plate is arranged between two stand columns on the left side; a right side plate is arranged between two stand columns on the right side; two bridge plates are transversely joined between the left side plate and the right side plate; the lifting car is arranged between the two bridge plates; a scissor type lifting device is arranged at the upper part of the lifting car; pressure stop plates respectively extend out from the front and back two side surfaces of the lifting car; and the outer ends of the pressure stop plates both extend above the bridge plates on the corresponding sides. The lifting car can freely move along the bridge plates when having no pressure, so that the parking position of the lifting car is conveniently adjusted; and meanwhile, the lifting car uses the bridge plates as rails, so that the utilization efficiency of the bridge plates is improved. When the lifting car works, a vehicle is pressed on the lifting car, and the pressure stop plates on the lifting car are pressed on the bridge plates to realize positioning and locking of the lifting car by the pressure stop plates through using elastic deformation of a shaft inserted in the lifting car and self-adaptive upward movement corresponding to the lifting car.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a four-column lift with a pressure-locked lifting vehicle. Background technique [0002] Since the 1990s, domestic lifts have gradually become popular. With the increase in the number of cars in our country, four-post lifts, as an important tool for car maintenance, have greatly increased their demand. Now the lift market has nearly a hundred Chinese and foreign brands, and hundreds of product series. The price of foreign brands is relatively high, but relying on their good product quality, stable performance, and simple equipment operation, they have established a good reputation among dealers. With the development of the domestic four-post lift industry in recent years, many improvements have been made in terms of product design, technology development and after-sales service, and sales have also greatly increased. [0003] The wheel lift type lift is the most commo...

AI Technical Summary

Problems solved by technology

[0003] The wheel lift type lift is the most common among the four-post lifts. People often need to loosen the suspension of the car when working under the four-post lift. Therefore, a lifting car is often installed on the four-post lift to jack up the axle. , to unload the suspension, but the lift car is easy to slide on the bridge plate, which is not conducive to the safety of the vehicle inspection process
