Crane lifting safety positioning apparatus

Abstract

The present invention discloses a crane lifting safety positioning apparatus, which comprises a track (1) and an electric hoist (2), wherein a wire rope drum (21), a wire rope (22), a guide fork (23), a guide rod (24) and a lifting hook (25) are arranged in the electric hoist (2), the electric hoist (2) is arranged in the track (1) and can move along the track (1), the crane lifting safety positioning apparatus is characterized by further comprising a sliding rod (3), a sliding sleeve (4), a bolt (5), a bracket (6) and a spotlight (7), the sliding rod (3) is arranged on the lower portion of the electric hoist (2), the sliding sleeve (4) sleeves on the sliding rod (3), the sliding sleeve (4) and the guide fork (23) are connected, the bracket (6) and the sliding sleeve (4) are connected, and the spotlight (7) and the bracket (6) are connected through the bolt (5). The crane lifting safety positioning apparatus has characteristics of simple structure, easy operation, fast and accurate positioning, safety and reliability.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a safety positioning device for driving hoisting. Background technique [0002] Now when the crane is carrying out the lifting operation, the worker locates the lifting point of the lifting by visually measuring the approximate drop point of the hook. Due to the large error of this positioning method, a large inclined lift often occurs, and an excessively large inclined lift may It will damage the guide fork, cause the steel wire rope to be tangled and cannot be lifted, and has to be repaired, and the maintenance workload is large. In addition, too much inclined hanging may also damage the steel wire rope, causing a safety hazard. Contents of the invention [0003] The object of the present invention is to provide a safety positioning device for driving hoisting with simple structure, convenient operation, fast and accurate positioning, safety and reliability. [0004] In order to achieve ...
