Embodiment approach

[0015] Such as figure 1 As shown, this embodiment is a high-rise, towering structure construction climbing formwork hydraulic synchronous control system with two sets of oil cylinder jacking mechanisms. The system includes a fuel tank 7, an oil pump 8, a transmission pipeline system, two sets of oil cylinder jacking mechanisms, and a synchronous control device. The transmission pipeline system includes oil suction branch L1, oil return branch L2 and electromagnetic reversing valve 17, and each set of oil cylinder jacking mechanism includes jack 18, hydraulic control check valve 2 and two-position three-way control valve 4, and the The jack 18 has a rodless cavity (upper cavity) and a rod cavity (lower cavity). The synchronous control device is composed of a synchronous valve 5 and a one-way speed regulating valve 6 connected in series.

[0016] The jacking mechanisms of the two oil cylinders are installed on the load-bearing mechanism 1 of the formwork, the jack 18, the hydr...

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...
