TECHNICAL FIELD

[0001] The utility model relates to a split type hydraulic station based on modularization belongs to hydraulic station field. BACKGROUND

[0002] The split type hydraulic station is a system that separates each function module of a hydraulic system, and each module is responsible for a specific function and integrated together through pipelines or connectors. The modular design makes the hydraulic station more flexible, easy to maintain and expand. The oil filter is a commonly used facility in the hydraulic station. The oil filter is installed between the hydraulic pump and the valve body. A threaded cover is threadedly connected to the oil filter. After the oil filter is used for a period of time, it needs to be disassembled and cleaned. However, some hydraulic oil is usually left in the pipeline connected to the threaded cover. Therefore, when the oil filter is separated from the threaded cover, the hydraulic oil left in the pipeline will drip from the pipeline connected to the threaded cover, affecting the cleanliness of the surface of the hydraulic station. Therefore, a split type hydraulic station based on modularization is needed to prevent hydraulic oil from dripping randomly when the oil filter is disassembled. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a split type hydraulic station based on modularization to solve the problems raised in the background art. The utility model prevents hydraulic oil from dripping randomly when the oil filter is disassembled.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-3 This utility model provides a technical solution: a modular split hydraulic station, including a frame 1, a hydraulic oil tank 6 installed inside the frame 1, a second pressure gauge 15 installed on the upper surface of the hydraulic oil tank 6, a hydraulic pump 2 installed on the upper surface of the hydraulic oil tank 6, the inlet end of the hydraulic pump 2 connected to the hydraulic oil tank 6, the outlet end of the hydraulic pump 2 connected to a threaded cover 3 through a pipe, an oil filter 14 threadedly connected to the threaded cover 3, the threaded cover 3 connected to a six-position five-way valve 5 through a pipe, the six-position five-way valve 5 installed on the upper surface of the hydraulic oil tank 6, a return oil pipe 18 extending to the bottom of the hydraulic oil tank 6 installed at the bottom of the six-position five-way valve 5, and a first pressure gauge 4 installed on the upper surface of the six-position five-way valve 5. By installing the hydraulic pump 2, the six-position five-way valve 5, etc., on the hydraulic oil tank 6, the main components of the hydraulic station, such as the hydraulic pump 2 and the six-position five-way valve 5, can be combined in a split manner, which is convenient for disassembly and expansion.

[0025] See Figure 1 , Figure 2 , Figure 4 and Figure 5A top box 16 is located directly below the oil filter 14. A side box 12, communicating with the top box 16, is installed on one side of the top box 16. The contact part between the side box 12 and the top box 16 is snapped into the corner of the upper surface of the frame 1. A U-shaped plate 9 is provided on one side of the side box 12. A rectangular cross-section insertion interface 22 is opened on the side of the U-shaped plate 9 facing the side box 12. A rectangular cross-section insertion plate 11 is inserted into the insertion interface 22. The insertion plate 11 is connected and fixed to the side box 12. The two ends of the U-shaped plate 9 extend to the two sides of the frame 1 connected to the side box 12, respectively. Small holes 23 are opened at both ends of the U-shaped plate 9. A positioning nut 8 is provided on one side of the small hole 23, concentrically arranged with the small hole 23. The positioning nut 8 is connected and fixed to the U-shaped plate 9. A limit screw 7 is threaded into the positioning nut 8. The positioning screw locally increases the thickness of the part of the U-shaped plate 9 where the limit screw 7 is installed, which is beneficial to reducing the thickness of the U-shaped plate 9. The top box 16 is positioned directly below the oil filter 14, and the structure formed by the top box 16 and the side box 12 is secured at the corner of the upper surface of the frame 1. Then, the plug plate 11 on the side box 12 is inserted into the plug interface 22. Subsequently, the limiting screws 7 at both ends of the U-shaped plate 9 are brought into contact with the two parallel sides of the hydraulic oil tank 6. At this time, the limiting screws 7 are in contact with the frame 1, thereby limiting the position of the structure formed by the side box 12 and the top box 16. This completes the assembly of the structure formed by the side box 12 and the top box 16 with the frame 1. When the threaded cover 3 and the oil filter 14 are disassembled, the hydraulic oil remaining in the pipe connected to the threaded cover 3 will drip into the space formed by the top box 16 and the side box 12, achieving centralized collection of the dripping hydraulic oil, reducing the waste of hydraulic oil, and preventing the hydraulic oil from dripping randomly when disassembling the oil filter 14, which helps to maintain the overall cleanliness of the hydraulic station.

[0026] See Figure 1 , Figure 2 and Figure 4 The bottom of the side box 12 is equipped with an oil drain pipe 21 that communicates with the side box 12. The lower end of the oil drain pipe 21 is threaded with a sealing cap 10. After opening the sealing cap 10, it is easy to drain the hydraulic oil in the space formed by the top box 16 and the side box 12. A sponge block 13 is inserted in the lower part of the top box 16. One end of the sponge block 13 extends into the side box 12 and fits against the inner wall of the side box 12. After the hydraulic oil drips into the top box 16, it will come into contact with the sponge block 13. The sponge block 13 buffers the hydraulic oil and prevents it from splashing randomly. This helps to reduce the depth of the top box 16. A connecting plate 19 is installed on the side of the top surface of the top box 16 away from the side box 12. The connecting plate 19 is connected to the L-shaped plate 17 through the fastener formed by the threaded head 20 and the nut. The horizontal part of the L-shaped plate 17 is connected to the threaded cover 3 through screws to support the threaded cover 3 and improve the stability of the structure.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
