Description

Technical Field

[0001] This utility model relates to the field of hydraulic station technology, and in particular to a high-power hydraulic station. Background Technology

[0002] A hydraulic power unit, as the power source of a hydraulic system, mainly consists of a booster pump, a drive motor, an oil tank, a control valve group, an accumulator, and auxiliary components. Its function is to transmit power through hydraulic oil to drive actuators such as hydraulic cylinders and hydraulic motors to complete predetermined actions. Conventional hydraulic power units typically use a single booster pump combined with basic components such as check valves and relief valves to construct the oil circuit. For example, Chinese Patent No. CN217055758U discloses a hydraulic power unit including an oil tank, a drive mechanism, an oil inlet mechanism, and an oil outlet valve mechanism; the drive motor... Both the oil inlet mechanism and the oil outlet valve mechanism are installed on the oil tank. The oil inlet mechanism is installed inside the oil tank and connected to the drive mechanism and the oil outlet valve mechanism. The oil outlet valve mechanism includes a valve body, a reversing valve, and a check valve. The reversing valve is installed on the valve body. The valve body has at least one oil inlet passage and at least two oil inlet and outlet passages. The first end and the second end of the oil inlet passage are respectively connected to the oil inlet of the oil outlet valve mechanism and the oil inlet of the reversing valve. The first ends of the two oil inlet and outlet passages are respectively connected to the two oil outlets of the reversing valve. The second ends of the two oil inlet and outlet passages are exposed on the outer wall of the valve body. The check valve is installed on the oil inlet passage.

[0003] Although the hydraulic station's outlet valve mechanism has a simple structure and can achieve liquid delivery with fewer valve bodies, saving on valve body and manufacturing costs, this type of hydraulic station has significant shortcomings in high-power applications: First, a single pumping mechanism cannot meet the demand for large flow rates, resulting in low oil delivery efficiency; second, pressure regulation relies on mechanical valves, which have slow response speeds and insufficient control precision; in addition, existing hydraulic stations require shutdown for maintenance, affecting the continuity of operations, and lack effective pressure relief and oil filtration mechanisms, which can easily cause system pressure fluctuations and oil contamination.

[0004] Therefore, there is an urgent need for a hydraulic station solution that can improve oil delivery efficiency, enhance pressure regulation flexibility, and adapt to high-power operating conditions. Utility Model Content

[0005] In view of the above situation and to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a high-power hydraulic station. The above technical objective is achieved through the following technical solution:

[0029] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1 To be continued Figure 5 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0030] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. Example

[0031] A high-power hydraulic power unit, comprising:

[0032] A hydraulic station base 1 is provided, and a terminal box 2 is provided at the upper end of the hydraulic station base 1. A first flow interface 201 and a second flow interface 202 are provided at the front end of the terminal box 2. The first flow interface 201 is located on one side of the second flow interface 202. The first flow interface 201 and the second flow interface 202 at the front end of the terminal box 2 are used to connect to an external hydraulic cylinder.

[0033] The terminal box 2 is equipped with an electromagnetic directional valve 203. The first flow port 201 and the second flow port 202 are connected to the electromagnetic directional valve 203. When the external hydraulic cylinder is working, the electromagnetic directional valve 203 can switch the oil circuit direction according to the oil supply and return requirements of the hydraulic cylinder to assist the hydraulic cylinder in fully extending and retracting.

[0034] The lower end of the hydraulic station base 1 is equipped with an oil storage tank 10 and an oil return tank 503. The external structures of the two are separated by a partition, but the bottom ends of the oil return tank 503 and the oil storage tank 10 are connected to each other through multiple pipelines.

[0035] A connector 3 is provided at the other port of the electromagnetic reversing valve 203.

[0036] Specifically, the connector 3 includes a first connecting pipe 301, a second connecting pipe 302, and a three-way pipe 303. The first connecting pipe 301 and the second connecting pipe 302 are installed in parallel on the booster suction pipe 403. The three-way pipe 303 is connected to one end of the first connecting pipe 301 and the second connecting pipe 302, and the three-way pipe 303 is installed inside the terminal box 2. The other end of the three-way pipe 303 is installed with the reversing solenoid valve. The first connecting pipe 301 and the second connecting pipe 302 are connected in parallel. The three-way pipe 303 is connected to the solenoid reversing valve 203 to realize oil circuit diversion or flow control.

[0037] The first connecting pipe 301 is equipped with a first solenoid valve 6 and a first pressure gauge 7, and the second connecting pipe 302 is equipped with a second solenoid valve 8 and a second pressure gauge 9. The oil pressure can be monitored and adjusted in real time. Under normal working conditions, only one of the first solenoid valve 6 and the second solenoid valve 8 needs to be opened to ensure that one of the first connecting pipe 301 and the second connecting pipe 302 is in operation. When maintenance is required, the circuit can be switched without stopping the machine. When the pressure of a single connecting pipe is too high, the first solenoid valve 6 and the second solenoid valve 8 can be opened at the same time to increase the flow of hydraulic oil in the pipe and reduce the pressure in the pipeline.

[0038] The transfer box 4 is located on the upper end of the hydraulic station base 1 and is located at one end of the connecting piece 3. A first oil pumping mechanism is connected to the side wall of the transfer box 4, and a second oil pumping mechanism is connected to the top of the transfer box 4. The transfer box is used to coordinate the first oil pumping mechanism and the second oil pumping mechanism to transport oil, and integrates a booster suction pipe 403. The first oil pumping mechanism and the second oil pumping mechanism are set in parallel. At the same time, hydraulic oil is drawn through the booster suction pipe 403. The whole system improves the oil delivery efficiency and adapts to the working environment with high power requirements by working in parallel with the dual oil pumping mechanisms.

[0039] The terminal box 2 is also equipped with an oil supply pipe 11. The oil supply pipe 11 has a built-in pump body, which can further help improve the oil supply efficiency. One end of the oil supply pipe 11 is connected to the inside of the oil storage tank 10, and the oil supply pipe 11 is connected to the solenoid reversing valve 203.

[0040] When the external hydraulic cylinder is working, the solenoid directional valve 203 controls the flow direction of the first flow port 201 and the second flow port 202. The first flow port 201 is set as A and the second flow port 202 is set as B. A is connected to the end of the piston rod of the hydraulic cylinder, and B is connected to the front end of the piston rod of the hydraulic cylinder. When the hydraulic cylinder needs to be pushed out, the oil supply pipe 11 is connected to A and the three-way pipe 303 is connected to B. According to the power requirements, the first oil pumping mechanism and the second oil pumping mechanism can work alone or simultaneously to pump oil from B. At this time, the pressure balance inside the hydraulic cylinder will force A to replenish oil from the oil supply pipe 11 into the hydraulic cylinder. When the hydraulic cylinder needs to be retracted, the oil supply pipe 11 is connected to B and the three-way pipe 303 is connected to A.

[0041] The first oil extraction mechanism and the second oil extraction mechanism are respectively provided with a first transfer connecting pipe 401 and a second transfer connecting pipe 402. The first transfer connecting pipe 401 and the second transfer connecting pipe 402 converge in the transfer box 4. The pressurized oil suction pipe 403 is connected to one end of the first transfer connecting pipe 401 and the second transfer connecting pipe 402. At the same time, the pressurized oil suction pipe 403 is also connected to one end of the connector 3.

[0042] The first oil pumping mechanism also includes a first oil pumping pipe 404, a first booster pump 405, and a first oil delivery pipe 406. The first booster pump 405 is located at the upper end of the hydraulic station base 1. The first oil pumping pipe 404 and the first oil delivery pipe 406 are both installed on the first booster pump 405. The first oil pumping pipe 404 is located at one end of the first transfer connecting pipe 401, and the first oil delivery pipe 406 is connected to the lower end of the hydraulic station base 1. The second oil pumping mechanism also includes a second oil pumping pipe. 407, second booster pump 408, second oil delivery pipe 409. The second booster pump 408 is located at the upper end of the hydraulic station base 1. The second oil extraction pipe 407 and the second oil delivery pipe 409 are both installed on the second booster pump 408. The second oil extraction pipe 407 is located at one end of the second transfer connecting pipe 402. The second oil delivery pipe 409 is also connected to the lower end of the hydraulic station base 1. The first oil delivery pipe 406 and the second oil delivery pipe 409 are both connected to the inside of the oil storage tank 10.

[0043] Both the first and second oil pumping mechanisms include a combination of a booster pump, a sucker pipe, and a delivery pipe. The booster pump drives the suction of hydraulic oil, which is drawn from the terminal box 2 into the pump body through the sucker pipe and then returned to the oil storage tank 10 through the delivery pipe.

[0044] A pressure relief return oil pipe 501 is installed on the side wall of the transfer box 4. The pressure relief return oil pipe 501 is connected to the booster suction oil pipe 403. The other end of the pressure relief return oil pipe 501 is connected to a filter 502. The lower end of the filter 502 is equipped with a return oil tank 503. When the system pressure is too high, the pressure relief return oil pipe 501 can release hydraulic oil into the return oil tank 503. During this return oil process, the filter 502 is also used to filter part of the returned hydraulic oil.
