AI Technical Summary

Technical Problem

Using lifting devices to lift heavy objects in confined spaces presents problems of low efficiency and safety hazards, especially in old residential staircases or construction sites, where materials are difficult to adjust their path flexibly, making them prone to collisions or people falling.

Method used

The lifting device, driven by a hydraulic system, combines chain drive and gear meshing to enable flexible up-and-down movement and forward-and-backward adjustment of the lifting rod. It also achieves precise stopping and safe placement of heavy objects through chain drive and pulley rails.

Benefits of technology

The lifting device can flexibly adjust the path in narrow spaces, reduce material damage, avoid the risk of bumps and falls, and improve transportation efficiency and safety.

Abstract

This utility model discloses an installation and lifting device for indoor decorative materials, including a base. A hydraulic rod is fixedly connected to the upper end of the base. A second gear is provided at the bottom of the cylinder, and the second gear meshes with a first gear. A threaded column is fixedly connected to the upper end of the second gear. Through this structure, the output end of a fourth motor is fixedly connected to the first gear. The first gear meshes with the second gear, driving the second gear to rotate. The rotation of the second gear causes the threaded column fixedly connected to it to rotate. When the threaded column rotates, it drives the threaded connecting rod connected to it to move up and down. An upper limiting ring limits the threaded connecting rod to prevent it from disengaging. A limiting groove is provided on the edge of the lifting rod to limit the rotation of the lifting rod and the threaded connecting rod. This allows the lifting rod to move up and down by rotating the motor, enabling heavy objects to be easily pulled into the floor according to their lifting height.
