All-steel adhesion type lifting scaffolding positive and negative rotation simultaneous lifting system and method

Abstract

The invention discloses an all-steel adhesion type lifting scaffolding positive and negative rotation simultaneous lifting system and method. The all-steel adhesion type lifting scaffolding positive and negative rotation simultaneous lifting system comprises a climbing frame and a lifting rope chain, and an electric hoist is fixedly installed at the lower part of the climbing frame; an upper lifting point is mounted at a high-order position of the climbing frame, and a lower lifting point is mounted at a low order of the climbing frame; a first guide wheel and a second guide wheel are arrangedon the lower lifting point, and a first wall-attaching lifting point and a second wall-attaching lifting point are separately installed on the upper and lower parts of the neutral position of a building wall; and the lifting rope chain comprises a first chain and a second chain and forms a closed loop with a guiding fine chain, and the closed loop bypasses the electric hoist, the first guide wheel, the second guide wheel, the upper lifting point and the wall-attaching lifting points in sequence. According to the all-steel adhesion type lifting scaffolding positive and negative rotation simultaneous lifting system and method, the climbing frame can be driven by the positive and negative rotation of the electric hoist to run upwards, and the lower parts of the first guide wheel and the second guide wheel are provided with a chain pre-tightening mechanism for facilitating the pre-tightening operation of the chains, thereby achieving the effects of bi-directional lifting and two-way pre-tensioning.

Description

technical field [0001] The invention discloses a forward and reverse simultaneous lifting system and method of an all-steel attached lifting scaffold, which belongs to the technical field of construction scaffold manufacturing according to the International Patent Classification (IPC). Background technique [0002] Attached lifting scaffolding, also known as climbing frame in the industry, is a support set up on construction sites for workers to operate and solve vertical and horizontal transportation. It is a new type of scaffolding system developed in recent years. It is mainly used in high-rise shear wall buildings. Can climb up or down buildings. [0003] The electric hoist of the traditional all-steel attached lifting scaffold lifting system is a one-way lifting. The specific structure: the electric hoist is fixed to the lower part of the lifting scaffold, the active chain hook of the electric hoist is fixed to the middle hanging point of the attached wall on the buildi...

AI Technical Summary

Problems solved by technology

[0008] 1. The electric hoist only lifts up when the whole system is running forward, and after the scaffolding is lifted to the set position, the electric hoist needs to rotate in the opposite direction to fix the chain hooks 1 and 2 to the hanging point of the last attached wall. This step It will take a long time and the efficiency is low;

[0009] 2. The chain is pre-tightened. Workers need to climb to the top of the frame to pre-tighten the chain, which is inconvenient to operate and poses a great safety hazard.
