Construction creeping formwork hydraulic synchronous control system of high-rise structure

Abstract

The invention provides a construction creeping formwork hydraulic synchronous control system of a high-rise structure, comprising an oil tank, an oil pump, a transmission pipeline system, two oil cylinder jacking mechanisms and a synchronous control device. The transmission pipeline system comprises an oil-absorbing branch, an oil-returning branch and an electromagnetic directional valve, and either oil cylinder jacking mechanism comprises jacks, a hydraulic one-way valve and two-position three-way control valves. The construction creeping formwork hydraulic synchronous control system is characterized in that either two-position three-way control valve is provided with an opening connected with the synchronous control device, an opening connected with a corresponding jack and an opening connected with the electromagnetic directional valve; the opening connected with the synchronous control device and the opening connected with the jack are communicated when the power is on; and the opening connected with the synchronous control device and the opening connected with the electromagnetic directional valve are communicated when the power is off. The construction creeping formwork hydraulic synchronous control system can favorably solve the problems of different motion speeds and asynchrony motion in various jacking machine positions, can automatically control the lifting speed and ensures stable and synchronous lifting.

Description

technical field [0001] The invention relates to a hydraulic synchronous system, in particular to a hydraulic synchronous control system for climbing forms in building constructions such as high-rise structure core concrete and large bridge main towers. Background technique [0002] The hydraulic climbing formwork system used in the construction of high-rises, super high-rises, high-rise structure core concrete, and large bridge main towers used to mainly rely on imported equipment. However, due to the high cost, the country has also begun to develop its own products. The current domestic technology has the disadvantages of complex structure, imperfect function, inconvenient operation and low labor rate. [0003] The climbing formwork system is generally equipped with two or more sets of jacking positions (cylinder jacking mechanism), and the load on the system is different in each position, so each jacking position of the climbing formwork system (oil cylinder jacking mecha...

However, due to the high cost, the country has also begun to develop its own products

The current domestic technology has the disadvantages of complex structure, imperfect function, inconvenient operation and low labor rate.

[0003] The climbing formwork system is generally equipped with two or more sets of jacking positions (cylinder jacking mechanism), and the load on the system is different in each position, so each jacking position of the climbing formwork system (oil cylinder jacking mechanism) Due to the different resistances overcome during jacking work, the movement speed of each jacking position (cylinder jacking mechanism) will be different, and the accumulated error will cause the climbing system to jam at least, and cannot climb normally; Damage to the mechanical parts of the climbing formwork system will have a great impact on the construction of the project

In order to solve the problem of synchronous lifting, similar foreign products mainly rely on strict control of the stacking of equipment and materials on the climbing formwork system, as well as frequent inspections by operators and frequent manual adjustment deviations. This manual method not only limits the use of the climbing formwork system functions, increased the work intensity of operators, and did not fundamentally solve technical problems

Some foreign companies use intelligent means such as computers and sensors to carry out synchronous control. However, due to the large investment in equipment, complex systems, high operation requirements, and difficult maintenance, they cannot be widely accepted by domestic enterprises.
