Embodiment 1

[0037] combine figure 1 and figure 2 As shown, this embodiment discloses a hydraulic cylinder oil circuit locking valve group 10 , and the locking valve group 10 includes a first unit module 11 and a second unit module 12 . Unit module 11 includes oil pipe 1 111, oil pipe 2 112, hydraulic control check valve 1 113, electromagnetic check valve 1 114, overflow valve 1 115, unloading check valve 1 116; unit module 2 12 includes oil pipe 3 121 , oil pipe four 122, hydraulic control check valve two 123, electromagnetic check valve two 124, overflow valve two 125, unloading check valve two 126; said oil pipe one 111, oil pipe two 112, oil pipe three 121, oil pipe four One end of 122 is provided with a plurality of oil ports, and the other end is an external oil port.

[0038] The oil inlet of the hydraulically controlled one-way valve 113, the oil outlet of the electromagnetic one-way valve 114, and the oil outlet of the unloading one-way valve 126 are respectively communicated w...

Embodiment 2

[0045] image 3 A connection relationship diagram between the hydraulic cylinder oil circuit locking valve group 10 and the jacking cylinder 20 is disclosed. Such as image 3 As shown, one locking valve group 10 controls two jacking cylinders 20 at the same time, of course, it can also control more or one, and the principle is the same. The jacking cylinder 20 includes two chambers. According to the position of the plunger rod of the jacking cylinder, the two chambers are respectively called the rodless chamber and the rod chamber. Both the rodless chamber and the rod chamber are provided with oil ports.

[0046] combine Figure 1 to Figure 3 As shown, the external oil port of the oil pipe 2 112 is connected with the oil port of the rodless chamber of the jacking cylinder 20 , and the external oil port of the oil pipe 3 121 is connected with the oil port of the rod chamber of the jacking cylinder 20 . In this case, the working mode one of the above-mentioned locking valve g...

Embodiment 3

[0050] Figure 4 A connection relation diagram between the locking valve group 10 and the three-position four-way proportional reversing valve 7 is disclosed. The external oil port of the first oil pipe 111 and the external oil port of the oil pipe four 122 are respectively connected with the three-position four-way proportional reversing valve 7, and the three-position four-way proportional reversing valve 7 is used to realize that the jacking cylinder 20 is extending the cylinder, When shrinking the cylinder in different working conditions, the hydraulic oil flow direction in the jacking cylinder 20 is changed.

[0051] The three-position four-way proportional reversing valve 7 includes an oil inlet P, an oil port A, an oil port B, and an oil return port T, wherein the oil port A and the oil port B are respectively connected to the external oil ports of oil pipe one 111 and oil pipe four 122 connected. The three-position four-way proportional reversing valve 7 is provided ...

Abstract

The invention discloses an integral steel platform jacking oil cylinder oil circuit controlling system. The system comprises a hydraulic pump station, a one-way valve, a plurality of jacking oil cylinder controlling units, and a PLC. An oil outlet hydraulic pipeline of the hydraulic pump station communicates with an oil inlet of the one-way valve, and a multi-oil-outlet pipeline is arranged at thean oil outlet of the one-way valve via a hydraulic hose. Each of the jacking oil cylinder controlling units comprises a three-position four-way proportional directional valve, a locking valve group and a jacking oil cylinder; and the three-position four-way proportional directional valve is used for realizing change of the hydraulic oil flow direction in the jacking oil cylinder in different working situations of the jacking oil cylinder including cylinder extending and cylinder retracting. The locking valve group is arranged on an oil circuit pipeline between the three-position four-way proportional directional valve and the jacking oil cylinder. The PLC is used for controlling the three-position four-way proportional directional valves and the locking valve groups to work. The integralsteel platform jacking oil cylinder oil circuit controlling system can be adapted to change of flow direction of hydraulic oil in an oil pipe, and has dual effects of locking and unloading in both flow directions of the hydraulic oil, so safe operation of the hydraulic oil cylinder is ensured.

Description

technical field [0001] The invention relates to an oil circuit control system for an integral steel platform jacking cylinder, in particular to a locking valve group used for the oil circuit control of the jacking oil cylinder of the integral steel platform formwork of a super high-rise building. 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] The overall steel platform gradually climbs up with the construction of the bu...
