Lifting device

Abstract

The invention provides a lifting device. The lifting device comprises a guide rail, a mounting rack, a loading platform, a power assembly, a lifting assembly, a locking assembly, a control assembly and a roller assembly; the roller assembly comprises fixed rollers and movable rollers, wherein multiple groups of the fixed rollers and the movable rollers are arranged on the mounting rack at intervals along the vertical direction; the fixed rollers are rotatably arranged at the inner side of the mounting rack, and are suitable for abutting against the front side of the guide rail; the movable rollers are arranged at the outer side of the mounting rack, and are suitable for abutting against the rear side of the guide rail; the fixed rollers and the movable rollers cooperate with each other torealize the horizontal limit and vertical movement of the mounting rack relative to the guide rail; and each movable roller comprises a rotating rod, a sliding block, a wheel body and a locking element. The lifting device provided by the invention has the advantages of being in modularized split arrangement, convenient in assembly and disassembly, safe and reliable, and stable in operation.

Description

technical field [0001] The invention relates to tool equipment, in particular to a lifting device. Background technique [0002] Lifting equipment is a device that enables people or things to move back and forth between low and high places. The important indicators of lifting equipment are: 1. Safety; 2. Detachability; 3. Has the function of crisis relief and escape. [0003] At present, the common lifting mechanisms include civil elevators and building elevators. Civilian elevators have high requirements for supporting facilities, and generally cannot be used for outdoor operations; cables are used for lifting, and cable breakage is prone to fall accidents. In addition, power failure during operation is not conducive to escape. Construction lifts are suitable for outdoor use, but steel pipe supports are required, making the construction relatively complex and costly. At the same time, construction lifts are lifted by cables, which are prone to fall accidents if the cables ...

AI Technical Summary

Problems solved by technology

However, in the follow-up use, the inventors found that several lifting devices in the past still had the following problems: (1) the volume was large, the overall weight was heavy, and it was inconvenient to carry and carry when working outdoors; The locking wheel assembly is essential for the limit along the horizontal direction, but before installing the mounting bracket to the guide rail, the locking wheel assembly must be removed first, then the mounting bracket is close to the guide rail, and finally the locking wheel assembly is installed on the The horizontal limit is realized on the outside of the guide rail; the loading and unloading process is time-consuming and laborious, and frequent loading and unloading will cause great damage to the fasteners, which are prone to loosening and pose a safety hazard; (3) there are still defects in function, especially in terms of intelligent control.
