Problems solved by technology

Although these semi-automatic hydraulic jacking systems solve the lifting problem of heavy loads, as the weight and volume of large buildings become larger and larger, the structure is complex, and the load distribution is uneven, the control accuracy and control points of the jacking are required. This requires the hydraulic jacking system to be able to realize multi-point synchronous lifting while supporting the building. The existing semi-automatic hydraulic jacking system can no longer meet the requirements of multi-point synchronous jacking. How to lift a super It has become a difficult problem for large buildings to coordinate and coordinate multiple points to complete high-precision synchronous lifting
At the same time, the jacking system itself is a complex system. How to ensure the stability and firmness of the support during the jacking process is also an urgent problem to be solved.

Abstract

The invention relates to a hydraulic synchronous jacking system which comprises four main oil cylinders, a console, a programmable controller, a switching power supply and eight electromagnetic reversing valves, wherein a proportional reversing valve, four upper bolt oil cylinders, four lower bolt oil cylinders and an opening device are arranged on each main oil cylinder; each electromagnetic reversing valve is used for controlling the four upper bolt oil cylinders or the four lower bolt oil cylinders on the same main oil cylinder; an encoder is arranged on each opening device, and output signal interfaces of the encoders are connected with a signal input interface of the programmable controller and the signal input interface of a touch screen; and the hydraulic synchronous jacking system further comprises an oil pump motor for controlling the main oil cylinders, the upper bolt oil cylinders and the four lower bolt oil cylinder. According to the hydraulic synchronous jacking system disclosed by the invention, the four main oil cylinders are adopted, each main oil cylinder is equipped with the four upper bolt oil cylinders and the four lower bolt oil cylinders, and stable and firm support of the system is ensured; and the programmable controller is adopted, and automatic synchronous control of the system can be realized by controlling the oil pump motor, the proportional reversing valves and the electromagnetic reversing valves.

Description

technical field [0001] The invention relates to the technical field of building hydraulic jacking, in particular to a hydraulic synchronous jacking system. Background technique [0002] At present, in order to meet the synchronous jacking requirements of large buildings, semi-automatic hydraulic jacking systems are generally used. Although these semi-automatic hydraulic jacking systems solve the lifting problem of heavy loads, as the weight and volume of large buildings become larger and larger, the structure is complex, and the load distribution is uneven, the control accuracy and control points of the jacking are required. increase, which requires the hydraulic jacking system to be able to realize multi-point synchronous lifting while supporting the building. The existing semi-automatic hydraulic jacking system can no longer meet the requirements of multi-point synchronous jacking. How to lift a super It has become a difficult problem for large buildings to coordinate and...
