Description

[0002] In the field of industrial automation and mechanical manufacturing, pneumatic and hydraulic systems are widely used in systems that require precise control and efficient energy conversion. These systems provide performance superior to that of a single pneumatic or hydraulic system by converting pneumatic energy into hydraulic energy. For example, pneumatic systems generally have the advantages of fast response and simple structure, but their output force is limited and insufficient to meet the requirements of certain high-load applications. On the other hand, hydraulic systems can provide greater force output and precise control, but their response speed is slow and the motor is always running, causing the hydraulic oil to generate high temperature, high energy consumption, and a relatively complex system.

[0003] The existing pneumatic hydraulic system uses an air-controlled pressure valve to control the automatic reversing of the piston. Its disadvantage is that the piston position cannot be determined. If the pressure of the piston in the middle position has reached the rated pressure, the entire system will stop working until the pressure drops and then continue to work. In addition, traditional gas-liquid booster cylinders or gas-liquid boosters are single-shot boosters, and the boosted oil output is limited by volume. Summary of the invention

[0014] When the oil return drive element compresses air into the second cavity, the first electrically controlled one-way valve opens and the booster rod returns, the hydraulic oil returns to the fully sealed liquid storage cavity through the second oil circuit, the booster cavity and the first oil circuit.

[0015] In some embodiments, the fully sealed liquid storage chamber includes a liquid storage cylinder barrel and two liquid storage cylinder covers, the liquid storage cylinder covers are provided with a first air inlet, an oil inlet and return port, and a first oil outlet, the execution chamber includes an execution cylinder barrel and two execution cylinder covers, the execution cylinder covers are provided with a first oil inlet and an oil outlet channel, the boosting chamber is provided with a second oil outlet and the first electrically controlled one-way valve at one end away from the oil outlet channel, the second oil outlet is connected to the first cavity of the workstation, and the second cavity is provided with a second air inlet.

[0038] For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] Regarding the drawings of the present application, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of the present specification. It should also be understood that the drawings are not drawn to scale.

[0040] Existing pneumatic hydraulic systems use pneumatically controlled pressure valves to achieve automatic reversing of the piston, but there are several problems. First, the system cannot accurately detect the position of the piston. When the piston is in the middle position and the pressure reaches the rated value, the entire system will stop and cannot be restarted until the pressure drops, which leads to low working efficiency. In addition, traditional gas-liquid booster cylinders or boosters are usually only able to perform single boosting, and the oil output is limited by its internal volume, which cannot meet the application requirements of multiple boosting.

[0041] Based on the above problems, Figure 1 As shown, the present specification provides a gas-liquid continuous pressurization device, including a fully sealed liquid storage chamber 2, an execution chamber 3, a pressurization chamber 4, an oil inlet drive element, a pressurization drive element and a control circuit, wherein hydraulic oil is arranged in the fully sealed liquid storage chamber 2, a first oil circuit connected between the fully sealed liquid storage chamber 2 and the pressurization chamber 4 is arranged, a second actuator 5 is arranged in the execution chamber 3, a pressurization rod 7 is arranged on the second actuator 5, a magnet is arranged on the second actuator 5, and magnetic induction switches are arranged at both ends of the moving path of the second actuator 5, the magnetic induction switch, the oil inlet drive element and the pressurization drive element are all connected to the control circuit, the control circuit controls the oil inlet drive element to input compressed air so that the hydraulic oil enters the pressurization chamber 4 through the first oil circuit, and controls the pressurization drive element to drive the second actuator 5 to move so that the pressurization rod 7 continuously pressurizes the hydraulic oil in the pressurization chamber 4, with such a configuration, through the magnet and the magnetic induction switch, the system can detect the piston position in real time, effectively solves the problem that the piston position cannot be determined in the traditional system, prevents the system from stagnating due to the piston staying in the middle position, and improves the system stability and operation efficiency.

[0042] Secondly, the control circuit allows the hydraulic oil to continuously enter the boost chamber by precisely controlling the oil inlet drive element and the boost drive element, and realizes continuous boosting of the oil through the movement of the second actuator. Compared with the traditional single boost device, this design breaks through the limitation of single boosting and can provide stable and continuous boosting output to adapt to work scenarios with higher requirements.

[0043] In addition, the control circuit of the device integrates the oil inlet drive element, the boost drive element and the magnetic induction switch to achieve automatic control. The system can autonomously adjust the boost process according to the piston position and oil pressure detected in real time, reducing human intervention and improving the intelligence level of the equipment.

[0044] In some embodiments, the second actuator 5 is a piston or a diaphragm. Figure 1 As shown in FIG. , the second actuator 5 is a piston.

[0045] In some embodiments, Figure 3 and Figure 4As shown, the boosting rods 7 are provided at both ends of the second actuator 5, the boosting chambers 4 are provided at both sides of the actuator chamber 3, and the fully sealed liquid storage chamber 2 and the two boosting chambers 4 are respectively provided with first oil paths in communication. When the boosting driving element drives the second actuator 5 to operate, the two boosting rods 7 achieve alternate boosting in the corresponding boosting chambers 4. With such an arrangement, through the alternate action of the two boosting rods 7, the system can complete the boosting work in one boosting chamber 4 while the other boosting chamber 4 is preparing for the next boosting cycle. This alternating boosting mechanism improves the continuity and efficiency of the boosting process and reduces waiting time and system pauses.

[0046] Secondly, since the boosting process is performed alternately between the two boosting chambers 4, the workload of each boosting chamber 4 and the boosting rod 7 is relatively uniform, which can reduce the friction and wear of the components and extend the service life of the equipment.

[0047] In some embodiments, the second actuator 5 is a piston slidably disposed in the execution chamber 3, the magnet 9 is a magnetic ring sleeved on the piston, the execution chamber 3 is provided with a fixed rod along the moving direction of the piston, and the two magnetic induction switches 10 are spaced apart on the fixed rod. With such a configuration, the non-contact design of the magnetic ring and the magnetic induction switch 10 reduces mechanical wear and improves the durability and reliability of the system. This wear-free detection method reduces maintenance requirements and extends the service life of the equipment. In addition, the non-contact sensing method is not affected by environmental factors such as oil and dust, and is suitable for working in complex and harsh environments, ensuring the stability and reliability of the equipment.

[0048] Second, as Figure 2 As shown, the present application provides a pneumatic hydraulic booster station, including the gas-liquid continuous booster device, the oil outlet end of the booster chamber 4 is provided with a solenoid valve 13, the pneumatic hydraulic booster station is usually used in conjunction with a workstation, the workstation is generally an oil cylinder, the solenoid valve 13 is connected to the control circuit, the solenoid valve 13 is mainly used for switching the oil supply circuit and the oil return circuit, the solenoid valve can quickly and accurately switch the oil supply and oil return paths, and realize precise control of the flow of hydraulic oil.

[0049] Thirdly, Figure 5 and Figure 6As shown, the present application provides a pneumatic hydraulic system, including the gas-liquid continuous pressurizing device, a workstation and an oil return drive element, wherein the workstation includes a first actuator 1 driven by hydraulic pressure and a first cavity 100 and a second cavity 101 arranged on both sides of the first actuator 1, a second oil circuit connected to the pressurizing cavity 4 and the first cavity 100 is arranged, and a first electrically controlled one-way valve 6 connected to the control circuit is arranged on the second oil circuit, and the first electrically controlled one-way valve 6 is a passage toward the first cavity 100; the oil inlet drive element output The compressed air is introduced so that the hydraulic oil enters the first cavity 100 through the first oil circuit, the boosting chamber 4 and the second oil circuit, and drives the first actuator 1; the boosting driving element is used to drive the second actuator 5 to move so that the boosting rod 7 continuously boosts the hydraulic oil in the boosting chamber 4, and continuously injects the boosted hydraulic oil into the first cavity 100; when the oil return driving element compresses air to the second cavity 101, the first electrically controlled one-way valve 6 is opened and the boosting rod 7 returns, the hydraulic oil returns to the fully sealed liquid storage cavity 2 through the second oil circuit, the boosting chamber 4 and the first oil circuit. In this way, continuous boosting is achieved through the gas-liquid continuous boosting device, and the hydraulic oil can be continuously boosted and transported to the workstation. At the same time, the boosted oil output is not limited by volume, making the entire device more compact and enabling the device to meet higher hydraulic requirements, especially in applications that require long-term and high-intensity operations.

[0050] In some embodiments, the fully sealed liquid storage chamber 2 includes a liquid storage cylinder 200 and two liquid storage cylinder covers 201, and the liquid storage cylinder covers 201 are provided with a first air inlet 202, an oil inlet and return port 203, and a first oil outlet 204. The execution chamber 3 includes an execution cylinder 300 and two execution cylinder covers 301, and the execution cylinder covers 301 are provided with a first oil inlet 302 and an oil outlet channel 303. The end of the boost chamber 4 away from the oil outlet channel 303 is provided with a second oil outlet 400 and the first electrically controlled one-way valve 6, and the second oil outlet 400 is connected to the first cavity 100 of the workstation, and the second cavity 101 is provided with a second air inlet 102. The design of the fully sealed liquid storage chamber 2 and the execution chamber 3 makes the layout of the system components reasonable and reduces the overall space occupied by the system. The setting of each interface such as the air inlet, oil inlet and oil outlet helps to achieve close connection and effective cooperation between components.

[0051] In some embodiments, a plurality of sealing structures 8 are provided between the boost rod 7 and the oil outlet channel 303, and are respectively located on the front and rear sides of the first oil inlet 302. The setting of the sealing structure 8 greatly reduces the possible leakage of hydraulic oil during the boosting process, ensures the stability and efficiency of the system, helps to maintain the system pressure, and improves working performance.

[0052] Secondly, when the booster rod 7 is located at the initial position, the first oil inlet 302 is connected to the oil outlet channel 303, ensuring that the hydraulic oil can smoothly enter the oil outlet channel.

[0053] Fourthly, Figure 7 As shown, the present application provides another pneumatic hydraulic system, including the gas-liquid continuous boosting device and workstation, the workstation including a first actuator 1 driven by hydraulic pressure and a first cavity 100 and a second cavity 101 arranged on both sides of the first actuator 1; the second actuator 5 is a diaphragm, and boosting rods 7 are arranged on both sides of the diaphragm, and the ends of the boosting rods 7 are arranged with the magnets 9, the boosting chambers 4 are arranged on both sides of the actuator chamber 3, and the two boosting chambers 4 are respectively provided with the magnetic induction switches 10 corresponding to the magnets 9, and the magnetic induction switches are arranged outside the boosting chamber 4, and the boosting chamber 4 is provided with a first The one-way valve 11 and the second one-way valve 12, the fully sealed liquid storage chamber 2 is connected to the corresponding boosting chamber 4 through the two first one-way valves 11 respectively, the first one-way valve 11 is a passage toward the boosting chamber 4, the fully sealed liquid storage chamber 2 can continuously supply oil to the boosting chamber 4, and the continuous movement of the boosting rod 7 is realized through the diaphragm, the two boosting chambers 4 are connected to the first cavity 100 through the corresponding second one-way valve 12, the second one-way valve 12 is a passage toward the first cavity 100, through the design of the diaphragm and the boosting rod 7, the system can effectively convert pneumatic energy into hydraulic energy, perform continuous boosting, and improve the working efficiency of the system. Secondly, the combination of magnets and magnetic induction switches enables the system to accurately detect the position of the boosting rod and achieve precise control, which helps to improve the response speed and control accuracy of the system.

[0054] In some embodiments, a third oil circuit 14 is provided between the first cavity 100 and the fully sealed liquid storage cavity 2, and a second electrically controlled one-way valve 15 is provided on the third oil circuit 14. The second electrically controlled one-way valve is a passage toward the first cavity 100. The fully sealed liquid storage cavity 2 can normally supply oil to the first cavity 100. When oil return is required, it is only necessary to open the second electrically controlled one-way valve 15. The two boosting cavities 4 are connected to the third oil circuit 14 through the corresponding second one-way valves 12. The third oil circuit 14 can be used as both an oil supply circuit and an oil return circuit. The second one-way valve 12 can prevent the hydraulic oil from flowing back to the boosting cavity 4.

[0055] Secondly, the use of the second electrically controlled one-way valve 15 can achieve precise control of the flow path of the hydraulic oil, so that the system can flexibly adjust the flow direction of the liquid under different working conditions.

[0056] In summary, the above system drives the hydraulic oil directly to drive the piston through compressed air, so that the actuator cylinder is driven at high speed during the idle stroke, which not only saves energy but also reduces the cost of high-speed driving of the entire system.

[0057] At the same time, the above system eliminates the oil trapping phenomenon caused by process reasons in all hydraulic pumps, eliminates the temperature rise of hydraulic oil, increases the service life of hydraulic oil, eliminates motor idling, and reduces energy consumption by more than 80% in some areas. For existing booster cylinders and superchargers, when the effective boost stroke is long and the required pressure oil capacity is large, the pneumatic-hydraulic conversion hydraulic circuit plus the continuous boosting system can perfectly solve the above problems.

[0058] The above system can perfectly control the output hydraulic end pressure by adjusting the pressure of compressed air, and there is no hydraulic output overload burning motor phenomenon and pressure pulsation phenomenon in ordinary hydraulic systems.
