Load control device for attached lifting scaffold

Abstract

The invention discloses a load control device for an attached lifting scaffold, which comprises an electric control system and a sensor, wherein the sensor is electrically connected with the electric control system; and the electric control system is provided with a program for controlling the operation of a power unit of the attached lifting scaffold. The load control device is characterized in that the sensor comprises a piston shell and a piston rod, the piston shell is connected with a lifting beam of the attached lifting scaffold, the piston rod is connected with an electric block, an oil duct outlet is arranged in the piston cavity on the lower end of the piston rod and connected with the inlet of a controllable hydraulic non-return valve through a pipeline, the outlet of the controllable hydraulic non-return valve is connected with a transparent oil pipe, the transparent oil pipe is provided with a photoelectric switch for detecting the liquid level, and the photoelectric switch is electrically connected with the electric control system; and the controllable hydraulic non-return valve is provided with a control device which controls oil to flow from the inlet to outlet or from the outlet to inlet in a single direction. By adopting the technical scheme, the lifting load of the scaffold can be effectively limited, and overload and danger are prevented.

Description

technical field [0001] The invention relates to a load control device for preventing individual equipment from being overloaded during the operation of multiple lifting equipment, in particular to a device for preventing overload during the operation process of an attached lifting 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...

AI Technical Summary

Problems solved by technology

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 the scaffold on different electric hoists. Some electric hoists are less loaded or even not loaded at all, while some electric hoists have load concentration. , causing the frame to deform or the chain of the electric hoist to break, and the frame to fall
