Description

Technical Field

[0001] This utility model relates to the field of hydraulic station technology, specifically to a leak-proof hydraulic system power station. Background Technology

[0002] In modern industrial production, hydraulic power units, as an important power supply device, are widely used in various types of machinery. They transmit and convert energy through the pressure of hydraulic oil to drive actuators to complete various complex tasks. However, in actual operation, hydraulic power units face many challenges, among which leakage caused by loose oil pipe joints is particularly prominent.

[0003] When a hydraulic power station is in operation, the hydraulic oil in the oil pipes flows under high pressure, with frequent pressure fluctuations. Simultaneously, the equipment's own operational vibrations and the influence of the external environment cause the oil pipe joints to be subjected to alternating stress over a long period. Most existing hydraulic power stations use traditional threaded connections for their oil pipe joints. Under long-term high-pressure and vibration conditions, this type of connection is highly susceptible to loosening. Once the joint loosens, hydraulic oil will leak from the gaps.

[0004] Hydraulic oil leaks not only waste energy, reduce the efficiency of hydraulic systems, and increase operating costs, but also potentially pollute the surrounding environment. If leaked hydraulic oil comes into contact with open flames or other hazardous factors, it could even pose a risk of fire or other safety accidents. Furthermore, frequent leak repairs require downtime for maintenance, which undoubtedly affects the normal operation of equipment, reduces production efficiency, and causes unnecessary economic losses for the company.

[0005] Therefore, it is necessary to provide a leak-proof hydraulic system power station to solve the above problems. Utility Model Content

[0021] It also includes a collection frame 5 fixedly connected to the hydraulic station body 1, a control valve 6 installed on one side of the collection frame 5, and a first hexagonal nut 401 and a second hexagonal nut 411 located on the other side of the collection frame 5; The limiting unit is installed on the side of the assembly frame 5 near the first hexagonal nut 401 and the second hexagonal nut 411. The limiting unit has a connecting frame 7 and a limiting block 8. The connecting frame 7 is fixedly connected to the assembly frame 5, and the limiting block 8 is slidably installed in the connecting frame 7.

[0022] The connecting frame 7 has a vertically opened slide groove 71, and a top cover 72 is installed on the top of the slide groove 71. One end of the limiting block 8 slides in the slide groove 71.

[0023] The bottom of the limiting block 8 is provided with a nut limiting groove 82 and an oil pipe limiting groove 83. The oil pipe limiting groove 83 is located at the end of the limiting block 8. The nut limiting groove 82 has a semi-hexagonal shape and its size matches the first hexagonal nut 401. The oil pipe limiting groove 83 has a semi-circular shape and its size matches the diameter of the first oil pipe 4.

[0024] The top of the limiting block 8 located in the slide groove 71 has a magnetic part 81, and the material of the top cover 72 is a magnetic material.

[0025] The bottom sides of the limiting block 8 have connecting parts 84 extending outward, and the connecting parts 84 have several connecting holes for connection.

[0026] The nut limiting groove 82 located in the limiting units at the upper and lower ends of the first hexagonal nut 401 and the first oil pipe 4 is directly opposite to the first hexagonal nut 401, and the oil pipe limiting groove 83 is directly opposite to the first oil pipe 4. The upper and lower connecting parts 84 are fixedly connected by installing fasteners in the connecting holes.

[0027] The pipeline transmission unit also includes a first motor 2 and a second motor 21. The output end of the first motor 2 is connected to a first hydraulic pump 3. One end of the first hydraulic pump 3 is connected to the hydraulic station body 1, and the other end is connected to the first oil pipe 4. The output end of the second motor 21 is connected to a second hydraulic pump 31. One end of the second hydraulic pump 31 is connected to the hydraulic station body 1, and the other end is connected to the second oil pipe 41.

[0028] In one embodiment, how does this hydraulic station achieve leak prevention?

[0029] Specifically, a first oil pipe 4 and a second oil pipe 41 are installed on the first hydraulic pump 3 and the second hydraulic pump 31. The first oil pipe 4 is installed on the control valve 6 via a first hexagonal nut 401. When the first hexagonal nut 401 is rotated, the first oil pipe 4 rotates accordingly. Then, the second oil pipe 41 is installed on the control valve 6 via a second hexagonal nut 411. When the second hexagonal nut 411 is rotated, the second oil pipe 41 rotates accordingly. The positions of the first hexagonal nut 401 and the second hexagonal nut 411 are finely adjusted so that they correspond to the nut limiting groove 82 respectively. Then, the first... Oil pipe 4 and oil pipe 41 are respectively connected to the first hydraulic pump 3 and the second hydraulic pump 31 through flanges. Pull the upper and lower limit blocks 8 of the first hexagonal nut 401 so that the upper and lower nut limit grooves 82 surround the first hexagonal nut 401. At the same time, the first oil pipe 4 is also located in the oil pipe limit groove 83. Meanwhile, the connection holes on the upper and lower connection parts 84 are concentrically set. The connection holes are fastened with screws and nuts to fix the upper and lower limit blocks 8. The second hexagonal nut 411 is connected in the same way. When it is necessary to adjust the position of the first oil pipe 4 and the second oil pipe 41, loosen the fasteners of the upper and lower limit blocks 8, and move the limit blocks 8 inward toward the connecting frame 7. When the limit blocks 8 reach the limit position in the slide groove 71, the magnetic part 81 is attracted to the top cover 72 to prevent the upper limit blocks 8 from falling due to gravity. The upper and lower limit blocks 8 of the second oil pipe 41 are disassembled in the same way as above.

[0030] In summary, this hydraulic station employs a limiting block 8 at the connection between the first oil pipe 4 and the second oil pipe 41 near the control valve 6. This allows the corresponding first hexagonal nut 401 and second hexagonal nut 411 to be confined within the nut limiting groove 82. This ensures that the first hexagonal nut 401 and second hexagonal nut 411 are held abutted by the inner wall of the nut limiting groove 82, preventing loosening even during vibrations of the hydraulic station. An oil pipe limiting groove 83 extends from one end of the nut limiting groove 82, confining the pipe sections of the first oil pipe 4 and second oil pipe 41 near the first hexagonal nut 401 and second hexagonal nut 411 within the oil pipe limiting groove 83. This prevents bending and leakage at the connection point. The limiting unit provides comprehensive limiting protection for the connection node, further enhancing the reliability of the joint and providing structural assurance for the efficient operation of the hydraulic system.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
