Synchronous lifting control method for construction exterior rack

Abstract

The invention discloses a synchronous lifting control method for a building outer frame. 1. A stroke switch is set on the rotating shaft of each electric hoist; 2. The on-off times of the stroke switch of each electric hoist are input into a microprocessor, and the Perform processing and calculation according to the program set in it, and the micro-processor sends a control signal to each electric hoist to control the start and close of each electric hoist; 3. The microprocessor automatically designates an electric hoist as the reference hoist, if a certain When the difference between the on-off times of the limit switch of an electric hoist and the on-off times of the limit switch of the reference hoist is greater than or less than the preset value in the micro-processing, the micro-processing will send a signal of closing or starting to the electric hoist ; 4. When the difference between the on-off times of the travel switch of the electric hoist exceeding the set ratio and the on-off times of the reference hoist is positive or negative, the micro-processing will send a start or close signal to the reference hoist. The method of the invention can control a plurality of electric hoists to operate synchronously during lifting, so that each component part of the scaffold can be raised synchronously.

Description

technical field [0001] The invention relates to a scaffold used in the field of high-rise buildings, in particular to a method for synchronously lifting and lowering a building outer frame for controlling the synchronous lifting of an electric lifting type building outer frame. Background technique [0002] In the field of civil high-rise building construction, a full house of scaffolding was initially used, that is, it was built from the ground upwards, and it rose synchronously with the rise of the building. meters or higher; this kind of full house scaffolding is gradually abandoned by construction units because it consumes a lot of pipes and fasteners, requires a lot of labor to build, and has certain safety hazards and other unfavorable factors. In high-rise or super high-rise buildings, the construction unit has already or will soon adopt a liftable outer frame to replace the traditional scaffolding. Such as the technical scheme disclosed in the Chinese invention pate...

Problems solved by technology

[0004] The present invention aims at the aforementioned disadvantages that the lift-type scaffolding in the prior art cannot or is difficult to achieve synchronous operation when lifting, or although it can achieve synchronous operation, the equipment price is high, and provides a simple and practical control method with a very low equipment price The synchronous lifting control method of building outer frame
