Embodiment
Referring to figs. 1 through Fig. 3, the utility model embodiment is described further.
A kind of computer monitoring for strobe system, comprise touch-screen, PLC, gate level meter, water-level gauge and gate hoist, described gate hoist comprises fuel tank, oil pump, the first oil cylinder and the second oil cylinder; The oil-in of described oil pump is connected with fuel tank by oil pipe 5, the oil-out of described oil pump is connected with a hydraulic fluid port of the first oil cylinder and the second oil cylinder by oil pipe 5, described first oil cylinder is connected with fuel tank by oil pipe 5 with another hydraulic fluid port of the second oil cylinder, and the oil pipe 5 between the oil-out of described oil pump and the first oil cylinder is provided with the first variable valve; Oil pipe 5 between the oil-out of described oil pump and the second oil cylinder is provided with the second variable valve; Oil pipe 5 between the oil-in of described oil pump and fuel tank is provided with pump valve; Described gate level meter comprises the first gate level meter and the second gate level meter; Described first gate level meter, the second gate level meter, the first variable valve, the second variable valve and oil pump are all connected with PLC.
Above scheme, carried out the lifting of control gate, and the duty of two oil cylinders depends on the situation of oil inlet quantity by the first oil cylinder and the second oil cylinder; In addition, the first gate level meter is for measuring the aperture of hydraulic switch gate side, and the second gate level meter is for measuring the aperture of hydraulic switch gate opposite side, and the gatage measured is delivered to PLC by the first gate level meter and the second gate level meter; Therefore, in the lifting process of hydraulic switch gate, if the side aperture of hydraulic switch gate is greater than opposite side, so PLC will control suitably reduce the aperture of the first (the second) variable valve or increase the aperture of the second (the first) variable valve, change the oil inlet quantity of the first oil cylinder and the second oil cylinder, result reaches two lateral balances again by the first oil cylinder and the second oil cylinder hydraulic control open-close sluice gate exactly.
Concrete, as shown in Figure 3, be divided into upper oil cavitie 1 and lower oil cavitie 2 in oil cylinder, separated by piston 3, the telescopic shaft of oil cylinder is fixedly connected with piston 3 simplified diagram of oil cylinder; Upper oil cavitie 1 is directly connected with fuel tank by oil pipe 5, and lower oil cavitie 2 is connected with the oil-out of oil pump by oil pipe 5; Telescopic shaft and the gate of oil cylinder are in transmission connection.Therefore, when to lower oil cavitie 2 oiling, expansion link 4 can be retracted into oil cylinder inside, and gate is risen, and meanwhile, the interior oil of upper oil cavitie 1 flow back in fuel tank by upper oil pipe 5; When the oil of lower oil cavitie 2 is detached, expansion link 4 stretches out oil cylinder, and gate is declined.In the present embodiment, the aperture of hydraulic switch gate both sides is detected respectively by two gate level meters, when having there is the different situation of hydraulic switch gate both sides aperture, PLC just can regulate the oil inlet quantity of the lower oil cavitie 2 of first, second oil cylinder by the aperture adjusting first, second variable valve, and then the offset deviation of regulating piston 3, finally make hydraulic switch gate both sides aperture identical.The embodiment of gate level meter is the technology that those skilled in the art should grasp, and therefore, the present embodiment repeats no more.
Further, described gate hoist also comprises the first three-position four-way valve and the second three-position four-way valve, wherein, the P mouth of the first three-position four-way valve is connected with the oil-out of oil pump by oil pipe 5, described first variable valve is arranged on the oil pipe 5 between the P mouth of the first three-position four-way valve and oil pump, the T mouth of described first three-position four-way valve is connected with fuel tank by oil pipe 5, the A mouth of described first three-position four-way valve is connected with this hydraulic fluid port of the first oil cylinder with by oil pipe 5, and the B mouth of described first three-position four-way valve is connected with this another hydraulic fluid port of the first oil cylinder by oil pipe 5; The P mouth of described second three-position four-way valve is connected with the oil-out of oil pump by oil pipe 5, described second variable valve is arranged on the oil pipe 5 between the P mouth of the second three-position four-way valve and oil pump, the T mouth of described second three-position four-way valve is connected with fuel tank by oil pipe 5, the A mouth of described second three-position four-way valve is connected with this hydraulic fluid port of the second oil cylinder with by oil pipe 5, and the B mouth of described second three-position four-way valve is connected with this another hydraulic fluid port of the second oil cylinder by oil pipe 5; Described first three-position four-way valve is all connected with PLC with the control end of the second three-position four-way valve.
Above scheme, when opening hydraulic switch gate, PLC controls two three-position four-way valves, the P mouth of two three-position four-way valves is communicated with A mouth, T mouth is communicated with B mouth, the oil that so oil pump exports just can enter into the lower oil cavitie 2 of oil cylinder, and the oil in oil cylinder upper oil cavitie 1 can be back in fuel tank; After the aperture of hydraulic switch gate reaches predetermined value, A, B mouth that PLC controls two three-position four-way valves disconnects with P, T mouth respectively, and so the aperture of hydraulic switch gate remains unchanged; When closing hydraulic switch gate, the P mouth that PLC controls two three-position four-way valves is communicated with B mouth, and A mouth is communicated with T mouth, and so the oil of oil cylinder lower oil cavitie 2 flow back into fuel tank by three-position four-way valve, and the oil that oil pump exports can enter into the upper oil cavitie 1 of oil cylinder.Therefore, by arranging first, second three-position four-way valve, unlatching and the state that can realize hydraulic switch gate on the one hand keep, on the other hand, when closing hydraulic switch gate, the oil pressure by increasing upper oil cavitie 1 to upper oil cavitie 1 oil transportation of oil cylinder can also be realized, promote hydraulic switch gate and decline, prevent hydraulic switch gate to be stuck.In addition, when hydraulic switch gate declines, PLC also can by the aperture of control two variable valve, and when ensureing that hydraulic switch gate declines, the aperture of its both sides is identical.
In addition, this PLC is also connected with warning device, when adjustment is broken down, when causing gate stuck, is reported to the police by warning device, to remind staff.
