Suspension and lifting system for large-area building, and using method thereof

Abstract

The invention discloses a suspension and lifting system for a large-area building, and a using method thereof, and particularly designs a multi-point hydraulic volume synchronization system controlledby a computer. According to the characteristics of the large-area building, the large-area building needs to be controlled in a partitioned mode in the lifting and horizontal-moving processes of thelarge-area building, position close-loop control is conducted between areas, and pressure closed-loop control is conducted in the areas. According to the suspension and lifting system, pressure closed-loop and position close-loop double-control selection modes can be achieved; and partitioned position control, area internal force suspension control and overall lifting speed control over a large-area component can be achieved, and overall precise control over overall suspension and lifting of the large-area component is achieved finally.

Description

technical field [0001] The invention relates to the technical field of building jacking, in particular to a large-area building suspension and lifting system and its application method. Background technique [0002] Synchronous jacking of large-area and complex structural parts is a complex control technology. The traditional way is that the pressure relief valve is lifted synchronously in different areas. Each point in the area is controlled by pressure, and the position is controlled synchronously between the areas. Due to the complexity of the component force and the characteristics of the support points, the pressure of the system in the area When controlling, there will be a large position out of sync in the area, which will cause a risk for the building to be lifted. [0003] If position and pressure control is also used for each point in the area, there will be a large number of control points, a large number of equipment requirements, high failure rate and high cost...

Problems solved by technology

The traditional way is that the pressure relief valve is lifted synchronously in different areas. Each point in the area is controlled by pressure, and the position is controlled synchronously between the areas. Due to the complexity of the component force and the characteristics of the support points, the pressure of the system in the area When controlling, there will be a large position out of sync in the area, which will pose a risk for building jacking

[0003] If position and pressure control is also used for each point in the area, there will be a large number of control points, a large number of equipment requirements, and a high failure rate and high cost of control valves during system operation, which also seriously affects the overall construction efficiency.
