Hoisting and automatic unhooking method of dike twisting body

Abstract

The invention relates to a hoisting and automatic unhooking method of a dike twisting body. The hoisting and automatic unhooking method comprises the following steps: 1: carrying out hoisting and automatic unhooking on the twisting body by a crane through an automatic unhooking device; 2: connecting one end of a first steel wire rope by a main hook of a rotary suspension arm through a hoisting ring and connecting the other end of the first steel wire rope with an upper load bearing point of a fixed hanger; 3: connecting one end of a second steel rope through a secondary hook and connecting theother end of the second steel rope with the lower end of a movable plate; 4: connecting a hoisting ring at one end of a suspender with an arc-shaped hoisting hook of the movable plate; connecting a hoisting ring at the other end of the suspender with a lower load bearing point of the fixed hanger; 5: pulling up the lower end of the movable plate to rise and enabling the arc-shaped hoisting hook to rise along the peripheral direction of a connecting pin shaft; when the arc-shaped hoisting hook of the movable plate and the suspender parallel to the ground automatically fall off, realizing automatic unhooking. The hoisting and automatic unhooking method provided by the invention has the advantages of improving the working efficiency, ensuring the construction progress, reducing the construction cost, alleviating the labor intensity, improving the working environment and realizing targets of energy saving and environment protection, and safety construction.

Description

technical field [0001] The invention relates to a hoisting and automatic decoupling method, in particular to a hoisting and automatic decoupling method for a dike torsion body. Background technique [0002] In the hoisting construction of the existing embankment twisting body, although it can be hoisted on the bank platform by a crane, it can be hoisted with common locks. However, due to the inability to automatically unhook, operators need to unlock the lock under the embankment and pass through the uneven embankment. The operation is difficult, the labor intensity is high, and the operation efficiency is low; It is easy to cause accidents, especially when working on embankments in the high temperature and open air, the working environment is harsh, and it is easy to cause heat stroke; some workers who are submerged in the twisting body cannot be decoupled, resulting in the failure of hoisting construction, which affects the construction period and brings economic losses. ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to overcome the defects of the prior art, and provides a method for hoisting and automatically uncoupling the torsion body of an embankment, which solves the problem that workers cannot unhook due to part of the torsion body being submerged in the water, and ensures that the construction operation can be carried out smoothly
