Problems solved by technology

The total pressure of the hydraulic oil in the hydraulic oil circuit should not be replaced frequently. In the existing technology, the control system of the jacking cylinder and the control system of the supporting corbel cylinder are often controlled by different hydraulic pumps and hydraulic pipelines. The construction cost is high and the cooperative work less effective

Embodiment 1

[0049] This embodiment discloses a hydraulic control system for the integral steel platform formwork of a super high-rise building, which will be further described below in conjunction with the accompanying drawings, wherein, figure 1 The schematic diagram of the hydraulic control system, Figure 2 to Figure 4 They are the three-dimensional view and the top view of the main structure of the hydraulic control system in two directions respectively.

[0050] combine Figure 1 to Figure 4 As shown, the hydraulic control system for the overall steel platform formwork of a super high-rise building includes a hydraulic pump station 1, a check valve 2, a system maximum oil pressure control component, several jacking cylinder control units, a support corbel control circuit, and a PLC control unit. Device 21.

[0051] The hydraulic pump station 1 includes components such as a fuel tank, a filter, a drive motor, and an oil suction pump. After the hydraulic pump station 1 is started, th...

Embodiment 2

[0079] This embodiment provides a hydraulic control method for the integral steel platform formwork of a super high-rise building, using the hydraulic control system for the integral steel platform formwork of a super high-rise building in Embodiment 1, and the control method includes the following steps:

[0080] Step 1. The PLC controller controls the reversing valve 4 to connect the overflow valve 15 to the hydraulic oil circuit. The jacking cylinder control unit controls the jacking cylinder 14 to perform cylinder extension operation, so that the overall steel platform is pre-lifted to a height H 1 . The pre-jacking height of the overall steel platform is centimeter level, such as H 1 =5cm. The specific process of the hydraulic cylinder extension operation is as follows: After the hydraulic pump station 1 is started, the hydraulic oil flows to the oil port of the hydraulic hose 3 through the check valve 2; the oil inlet of the reversing valve is connected with the relief ...

Abstract

The invention discloses a hydraulic control system and method for a formwork frame of an integral steel platform of a super high-rise building. Leg control circuit, and PLC controller; wherein the maximum oil pressure control components of the system include a reversing valve, relief valve 1, and relief valve 2; the jacking cylinder control unit and the supporting corbel control circuit are under the control of the PLC controller Collaborative work. The hydraulic control system sets the maximum oil pressure control component of the system, and when the working oil pressure required by the two working modes of the jacking hydraulic system and the supporting hydraulic system is greatly different and operates alternately, the relief valve 1 and the relief valve 2 are operated alternately. With the switching of the two working modes, it is alternately connected to the oil circuit system, so that the requirements of the two working modes can be met through a set of hydraulic pump station and oil supply pipeline, the construction cost is reduced, and the cooperative work effect is good.

Description

technical field [0001] The invention relates to a hydraulic control system and method for an integral steel platform formwork of a super high-rise building, and belongs to the field of steel platform formwork climbing equipment. Background technique [0002] The overall steel platform is the main platform in the construction process of modern super high-rise buildings, and its construction stability determines the safety of the building construction process. The construction platform is bulky and its own structural design is reasonable, which provides many conveniences for the construction process. Construction personnel and construction machinery can complete work activities on the construction platform, such as concrete shear wall reinforcement binding, wooden formwork presupport, concrete pouring and other processes. [0003] After the construction of the concrete shear wall of a building is completed, and the concrete load-bearing and compressive strength reach the stan...
