AI Technical Summary

Technical Problem

During the downward process of the four-pillar lift, if an obstacle appears below the beam, it is easy to cause the working platform to be imbalanced and the vehicle falls. The existing technology uses electronic components to detect and determine, which is costly and has low reliability.

Method used

A mechanical locking structure is designed, including a slide, a fuse plate, a locking block and a restriction hole. When the cross beam is inclined, the locking block is inserted into the restriction hole to prevent further tilting of the working platform and prevent the vehicle from sliding and falling.

Benefits of technology

Through the mechanical locking structure, the lift working platform is effectively prevented from tipping, reducing the risk of vehicle side slip and falling, and the structure is simple, low cost and high reliability.

Abstract

The utility model discloses a descending resistance locking structure of a four-column lifting machine, which comprises two mutually parallel girders, two mutually parallel cross beams and four stand columns, the two girders are arranged on the upper end surfaces of the two cross beams, the four stand columns are vertically arranged and respectively positioned at the two ends of the two cross beams, and the two cross beams are arranged on the upper end surfaces of the four stand columns. Sliding bodies are arranged at the two ends of the cross beam respectively, sliding rails allowing the sliding bodies to slide up and down are arranged on the side walls of the stand columns, safety plates are vertically arranged on the inner side walls of the sliding rails, locking blocks are arranged on the upper side walls of the ends, away from the cross beam, of the sliding bodies, and a plurality of limiting holes are evenly formed in the side walls of the safety plates in the vertical direction. The structure is simple and reasonable, the production and manufacturing cost can be reduced, and the working performance is stable and reliable.
