The present application is described in further detail below with reference to fig. 1.
The application provides a single-hydraulic solenoid valve sequential driving double-door control system, which comprises an actuating cylinder, a hydraulic solenoid valve 3, a bidirectional current-limiting valve and a one-way valve.
Specifically, the actuator cylinder comprises a first actuator cylinder 1 and a second actuator cylinder 2, the bidirectional flow limiting valve comprises a first bidirectional flow limiting valve and a second bidirectional flow limiting valve, the one-way valve comprises a first one-way valve and a second one-way valve, the first bidirectional flow limiting valve and the first one-way valve which are connected in parallel are arranged on a first oil pipeline connected with the first actuator cylinder 1, the second bidirectional flow limiting valve and the second one-way valve which are connected in parallel are arranged on a second oil pipeline connected with the second actuator cylinder 2, the directions of the first one-way valve and the second one-way valve are opposite, and the hydraulic solenoid valve 3 can simultaneously control the first actuator cylinder 1 and the second actuator cylinder 2.
In one embodiment of the present application, the first oil line is connected to the third oil line after being connected in parallel to the second oil line, and the hydraulic solenoid valve 3 is disposed on the third oil line. The first oil line is connected to the rodless chamber of the first actuator cylinder 1 and the second oil line is connected to the rodless chamber of the second actuator cylinder 2. The direction of the first check valve is the direction in which the oil of the first actuating cylinder 1 can flow out, and the direction of the second check valve is the direction in which the oil of the second actuating cylinder 2 can flow in. The left hatch is connected to the first actuator 1 and the right hatch is connected to the second actuator 2.
In the single-hydraulic solenoid valve sequentially-driven double-door control system, the right side cabin door is in compression joint with the left side cabin door, oil liquid in the second actuator cylinder 2 connected with the right side cabin door enters the rodless cavity of the second actuator cylinder 2 through the second one-way valve relatively quickly in the process of putting down, so the putting down speed is relatively high, and the oil liquid in the rodless cavity of the second actuator cylinder 2 can only pass through the second two-way flow-limiting valve due to the cut-off of the second one-way valve when the second actuator cylinder is put up, so the putting up speed is relatively low. On the contrary, in the process of putting down the first actuator cylinder 1 connected with the left side cabin door, oil can only enter the rodless cavity of the first actuator cylinder 1 through the first bidirectional flow limiting valve due to the cut-off of the first one-way valve, so the putting down speed is slow, and in the process of putting up the first actuator cylinder 1, the oil in the rodless cavity of the first actuator cylinder 1 can more quickly pass through the first one-way valve, so the putting up speed is higher. Thereby ensuring that the right side cabin door is pressed and the left side cabin door is prevented from collision in the retracting and releasing process.
The single-hydraulic electromagnetic valve sequential driving double-door control system can control a crimping cabin door and an undercarriage sequential actuating system through one hydraulic electromagnetic valve, and is simple in control method and high in reliability. Firstly, the control system only needs to control one electromagnetic valve, so that the complex logic judgment is reduced, and meanwhile, the failure rate of the electromagnetic valve is reduced to one half of the original failure rate; secondly, the number of electromagnetic valves is reduced by one, the number of pipelines is reduced by one, and the weight of the system is reduced; finally, the system has strong universality and has good optimization effect on various sequential actuating mechanisms with crimping relation and complex logic judgment.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
