AI Technical Summary

Technical Problem

In construction, when using two steel wire ropes to tie the ends of steel bars for lifting, imbalance often occurs, causing one steel bar to slip off, the entire bundle of steel bars to loosen and fall, endangering personnel safety and causing the mission to fail.

Method used

Design a safety hoisting device for building construction, which adopts a structure including a crossbeam, a limiting component, and a two-way screw rod. Through threaded connection and sliding groove limiting, it achieves rigid fixation of both ends of the steel bar, ensuring the stability of the hoisting process.

Benefits of technology

This effectively prevents steel bars from loosening and falling during hoisting, ensuring the safety of construction personnel and guaranteeing the successful completion of the hoisting task.

Abstract

The utility model discloses a safe hoisting device for building construction belongs to hoist field, crossbeam, prevent falling unit, it includes the limiting assembly of symmetrical setting at the bottom end of crossbeam for fixed reinforcement, the bottom end of crossbeam is provided with the chute, through the cooperation of above each device, in the use, first put the reinforcement into two groups of limiting assembly one by one, because the length of reinforcement, both ends will extend outside limiting assembly, then rotate two -way screw rod, both ends are connected with the connecting plate thread, and the connecting plate is limited by the chute, and the connecting plate will move along the chute to limiting assembly when rotating, drive the displacement of the limiting box of being connected together, finally, two groups of limiting box inner chamber extrude reinforcement one end respectively, realize rigid fixing, solve two steel wire ropes bundle reinforcement both ends hoist, hoist and carry frequently unbalance, and one steel bar slip will cause the whole bundle loose to fall, endanger personnel safety and the problem of task failure.
