Problems solved by technology

Although the hydraulic jacking device is not prone to explosion accidents, the disadvantage of using hydraulic pressure as power is that the jacking speed is too slow, which will prolong the entire construction time and increase the input cost of the project

Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific examples.

[0013] In this embodiment, a general control box controls two sub-control boxes, and each sub-control box controls six jacks as an example for illustration.

[0014] A multi-point synchronous hydraulic jacking system. Twelve jacks 7 are evenly divided into two groups. Each jack 7 is equipped with a displacement sensor 8 for detecting its displacement. The oil inlet end of each jack 7 is connected to There is an electromagnetic valve 6, and the output ends of six displacement sensors 8 in each group are all connected with a sub-control box 3, and the output ends of the sub-control box 3 are respectively electrically connected with six electromagnetic valves 6 in the same group; The oil inlet end of the solenoid valve 6 is connected to the oil pump 4 through the main oil pipe; the speed limiting valve 5 is arranged on the main oil pipe between the oil pump 4 and the solenoid val...

Abstract

The invention provides a multi-point synchronous hydraulic jacking system. The multi-point synchronous hydraulic jacking system comprises a plurality of jacks, wherein a displacement sensor is arranged on each jack and used for detecting displacement of the jack; a solenoid valve is connected with the oil inlet end of each jack; the output terminals of the displacement sensors are all connected with slave control boxes; the output terminals of the slave control boxes are electrically connected with the solenoid valves; the oil inlet ends of the solenoid valves are connected with an oil pump through a main oil pipe; and a speed limit valve is arranged on the main oil pipe between the oil pump and the solenoid valves. Multiple points can be controlled by the slave control boxes to work synchronously, and part of the points can be operated to work synchronously; and some independent point can also be independently regulated, so that the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of hydraulic jacking, and in particular relates to a multi-point synchronous hydraulic jacking system. Background technique [0002] At present, jacking devices are required in engineering fields such as the sliding form technology of building construction and the large tank flipping technology of installation engineering. And common jacking device generally adopts hydraulic pressure or air pressure as power. Since the pneumatic jacking device needs to compress the gas in a large-diameter tubular material such as a closed steel casing and steel pipe pile, it is prone to gas leakage and the risk of explosion. For large objects such as large-diameter tubular materials such as steel casings and steel pipe piles, once an explosion accident occurs, the consequences will be disastrous. Although the hydraulic jacking device is not prone to explosion accidents, the disadvantage of using hydraulic pressure as power...
