Roller assembly of lifting device

Abstract

The invention discloses a roller assembly of lifting device. The device comprises a plurality of sets of fixed idler wheels and a plurality of sets of movable idler wheels, and the fixed idler wheelsand the movable idler wheels are arranged on an installation frame at intervals in the vertical direction, the fixed roller is rotationally arranged on the inner side of the mounting frame and is suitable for abutting against the front side of the guide rail; the movable roller is arranged on the outer side of the mounting frame and is suitable for abutting against the rear side of the guide rail;the movable rolling wheel comprises a rotating rod, a sliding block, a wheel body and a locking piece, the rotating rod is rotationally arranged on the mounting frame in the horizontal direction, therear end of the sliding block is arranged on the rotating rod in a sliding mode, the wheel body is rotationally arranged at the front end of the sliding block, and the locking piece is movably arranged on the rotating rod; and the limiting block is suitable for abutting against the sliding block and is used for limiting the backward displacement of the sliding block. The locking device has the advantages of simplicity and convenience in operation, reliability in locking and stability 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.
