Abstract

The invention relates to a scaffold lifting assembly for buildings, in particular to a scaffold lifting device for buildings. The scaffold lifting device comprises a controller, a plurality of electric hoists matched with each other, a falling prevention mechanism and hydraulic sensors, wherein a vertical sliding cavity is formed, below a supporting seat, in the building, a sliding piston is arranged at the bottom of the supporting seat, the sliding piston is vertically and slidably connected in the sliding cavity, a reset spring is arranged in the sliding cavity, the sliding cavity communicates with the hydraulic sensors, the controller is used for controlling the electric hoists to lower a scaffold at a set distance, and the controller controls the electric hoists according to hydraulicdata transmitted by the hydraulic sensors until all the hydraulic sensors display the same hydraulic numbers. The scaffold lifting device detects the electric hoists without changing the structures ofthe electric hoists.

Description

technical field [0001] The invention relates to a lifting and lowering component of a building scaffold, in particular to a lifting device for a building scaffold. Background technique [0002] In the existing building construction technology, the attached lifting scaffold is widely used because of its less steel consumption, neat and beautiful appearance, and fast construction progress. The lifting process equipment generally adopts electric hoist. The upper hook of the electric hoist is connected to the building, and the lower hook is connected to the bottom of the scaffold. When the electric hoist is started, the scaffold body can be raised or lowered through the positive and negative rotation of the electric hoist. Often multiple electric hoists operate at the same time to realize the overall lifting of the scaffold. In this way, it is easy for the electric hoist to run fast or slow during the operation process, which leads to the redistribution of the self-weight of th...
