Lifting device for building-attached lifting scaffold

Abstract

The invention discloses a lifting device for a building-attached lifting scaffold (commonly known as 'climbing frame') or a building construction operation platform. The lifting device comprises a base, a lifting main machine, power boosting pulley blocks, a hinge, a tensioning mechanism and a chain. In the construction process, the base is fixed to the lower portion of a main frame of the attached lifting scaffold, the main machine is installed on the base, and the chain is wound across the power boosting pulley blocks and the lifting main machine. The number of the power boosting pulley blocks is two, and one power boosting pulley block is connected with a support of the attached lifting scaffold through the hinge. The tensioning mechanism is installed on the upper portion of the attached lifting scaffold. The lifting device can be matched with the universal attached lifting scaffold on the market, and ascends and descends along with a scaffold body. During construction, manual carrying is not needed, chain reversing is not needed, repeated wire disconnection and connection are not needed, the fault rate of equipment is reduced, the labor intensity of workers is relieved, the loss of the equipment is lowered, and the construction efficiency of a whole building is improved.

Description

technical field [0001] The invention belongs to hoisting and hoisting equipment, in particular to a lifting device for building attached lifting scaffolding. Background technique [0002] At present, the construction of high-rise and super high-rise buildings mostly uses building-attached lifting scaffolds (commonly known as "climbing frames") or building construction work platforms (hereinafter referred to as building construction work platforms or building-attached lifting scaffolds for short). Mainly slow-rising chain hoists. Limited by the lifting height, during the lifting process of the attached lifting scaffold, the slow-rising chain hoist needs to be manually transported to the upper floor for installation and fixing, re-arrange the power cable, and then reverse the chain for lifting. The force-bearing structure is fixed, and once the lifting operation is completed, the manual lifting cycle needs to be carried out again during the construction work on the higher flo...

AI Technical Summary

Problems solved by technology

2, laborious

The slow-rising chain hoist weighs up to 80 kg, and it is very labor-intensive to carry out manual handling and installation for many times

3. Equipment loss

The slow-rising chain hoist needs to be disassembled and installed many times, which will cause certain equipment failures

4. There are potential safety hazards

The chain lifting system does not need to disassemble the hoist during the cycle lifting or lowering process, but the upside-down hoist is heavy and the chain utilization rate is low. During the use process, the chain needs to be reversed many times to meet the building construction, which is time-consuming and labor-intensive and not energy-saving.
