Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, and in particular to an intelligent device integrating electro-hydraulic control of the main and auxiliary valves of a hydraulic support. Background Technology

[0002] In fully mechanized coal mining faces, electro-hydraulic directional valves are essential hydraulic components for operating and controlling mine hydraulic supports. They deliver high-pressure emulsion from the emulsion pump station to the corresponding actuators of the mine hydraulic supports according to the pre-determined coal mining process requirements, ensuring the safe and orderly operation of coal mining. This device is an innovative design to address issues related to the protection, ease of operation, and maintenance efficiency of electromagnetic control components in underground coal mine hydraulic support systems. By integrating multiple mechanical linkage structures, it achieves effective protection and efficient operation of the electromagnetic plate, ensuring the stability and reliability of the system.

[0003] Chinese utility model patent CN221682994U discloses an electro-hydraulic control directional valve for coal mine hydraulic supports. A threaded rod is placed inside a hollow tube, passing through the top of the control plate and inserting into the second limiting groove. A valve plate is then placed inside the feed hole, with the threaded groove on the top of the valve plate engaging with the threaded rod, facilitating easy assembly and disassembly. Finally, a gantry plate protects the electromagnetic plate. When the electromagnetic plate operates, it works with a magnet tube. When the magnet tube generates magnetic force, it drives the threaded rod to rise and fall, which in turn drives the valve plate to rise and fall, connecting the feed hole to the inlet. This achieves isolation between different feed routes in the same mining area, preventing overflow slurry and cleaning water from shutdowns from polluting the working environment and improving product efficiency.

[0004] In the existing design, the gantry plate is fixed to the control plate by multiple positioning bolts. Although this fixing method can provide a certain degree of stability and protection, in actual operation, every time the electromagnetic plate needs to be maintained or replaced, multiple positioning bolts must be unscrewed one by one before the gantry plate can be removed. This process is not only time-consuming and labor-intensive, but also prone to problems such as stripped bolts or loss. For modern coal mines that pursue high output, any unnecessary downtime is a huge blow to production efficiency.

[0005] Therefore, it is necessary to provide a new intelligent device for the electro-hydraulic control of the main and auxiliary valves of a hydraulic support to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an intelligent device integrating electro-hydraulic control of the main and auxiliary valves of a hydraulic support.

[0007] The hydraulic support main and auxiliary valve electro-hydraulic control integrated intelligent device provided by this utility model includes a control board. Hollow tubes are symmetrically connected to the top of the control board. Electromagnetic plates are provided on the top of the two hollow tubes. Protective components are provided at both ends of the top of the control board.

[0008] The protective component includes a rotating component and a limiting bracket. The bottom of the rotating component and the limiting bracket are fixedly connected to the two ends of the top of the control board, respectively. The limiting bracket has a limiting groove for engaging with the rotating component. The rotating component is located on the top of the electromagnetic plate, and the rotating component has a protective groove for engaging with the electromagnetic plate.

[0009] Furthermore, the rotating component includes two fixed columns, which are respectively fixedly connected to the top of the control panel. Rotating columns are rotatably connected to the adjacent sides of the two fixed columns. A protective plate is fixedly connected to the outer surface of the rotating column. An annular groove is provided at the end of the protective plate away from the rotating column, and a telescopic component is provided in the annular groove.

[0010] Furthermore, the protective groove is formed at the bottom of the protective plate, and the cross-sectional dimensions of the protective groove are larger than those of the electromagnetic plate.

[0011] Furthermore, the telescopic component includes a spring, one end of which is fixedly connected to the side wall of the annular groove, and the end of the spring away from the annular groove is fixedly connected to a telescopic column. The end of the telescopic column away from the spring extends out of the annular groove and is fixedly connected to a telescopic bracket. The bottom of the telescopic bracket near the end of the telescopic column is fixedly connected to a telescopic block that matches the cross-section of the limiting groove.

[0012] Furthermore, a tension ring is fixedly connected to the end of the telescopic bracket away from the telescopic column, and the tension ring is arranged in a ring shape.

[0013] Furthermore, a valve seat is fixedly connected to the bottom of the control board, and valve pipes are fixedly connected to both sides of the control board.

[0014] Furthermore, the control board has a material conveying hole inside, and the bottom of the valve seat has a material inlet, which is connected to the material conveying hole.

[0015] Compared with related technologies, the intelligent device for electro-hydraulic control of the main and auxiliary valves of the hydraulic support provided by this utility model has the following advantages:

[0016] This intelligent electro-hydraulic control device for the main and auxiliary valves of the hydraulic support allows for easy unlocking and rotation of the protective plate by simply pulling the pull ring, eliminating the need for complicated tools or procedures and greatly improving the efficiency of on-site maintenance. When the telescopic block resets and fits tightly with the limit groove, a stable self-locking state is formed, ensuring that the protective plate will not open accidentally and increasing the safety of the system.

[0017] The protective groove design ensures that the electromagnetic plate is completely covered when not in operation, effectively preventing coal dust, water vapor and other pollutants from entering and extending the service life of the electromagnetic plate. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 , Figure 1 A schematic diagram of the overall structure of the intelligent device for electro-hydraulic control of the main and auxiliary valves of the hydraulic support provided by this utility model; Figure 2 A schematic diagram of the integrated electro-hydraulic control intelligent device for the main and auxiliary valves of the hydraulic support provided by this utility model; Figure 3 Schematic diagram of the state structure of the protective component provided by this utility model Figure 1 ; Figure 4 Schematic diagram of the state structure of the protective component provided by this utility model Figure 2 ; Figure 5 A cross-sectional view of the protective component provided by this utility model.

[0026] In the specific implementation process, such as Figures 1 to 5 As shown, the intelligent device for electro-hydraulic control of the main and auxiliary valves of the hydraulic support provided by this utility model includes a control board 1. Hollow tubes 2 are symmetrically connected to the top of the control board 1. Electromagnetic plates 3 are provided on the top of the two hollow tubes 2. Protective components are provided at both ends of the top of the control board 1.

[0027] The protective component includes a rotating part and a limiting bracket 6. The bottom of the rotating part and the limiting bracket 6 are fixedly connected to the two ends of the top of the control plate 1, respectively. The limiting bracket 6 is provided with a limiting groove 7 for engaging with the rotating part. The rotating part is located on the top of the electromagnetic plate 3, and the rotating part is provided with a protective groove 11 for engaging with the electromagnetic plate 3.

[0028] While traditional fixed protective covers can provide some protection, they are not conducive to daily maintenance and quick replacement. The hydraulic support main and auxiliary valve electro-hydraulic control integrated intelligent device provided by this utility model adopts a multi-component collaborative design of rotating parts, limit brackets 6, telescopic buffer structure, and tension ring 17. It has a protective structure that has both good sealing performance and is easy to maintain. It is mainly designed to adapt to the complex working conditions in underground mines. The underground environment of coal mines is harsh and contains a large amount of coal dust, water vapor, vibration and other factors.

[0029] The rotating component includes two fixed columns 8, which are fixedly connected to the top of the control plate 1 respectively. Rotating columns 9 are rotatably connected to the adjacent sides of the two fixed columns 8. A protective plate 10 is fixedly connected to the outer surface of the rotating column 9. An annular groove 12 is provided at the end of the protective plate 10 away from the rotating column 9. A telescopic component is provided in the annular groove 12.

[0030] The protective groove 11 is located at the bottom of the protective plate 10, and the cross-sectional dimension of the protective groove 11 is larger than that of the electromagnetic plate 3. During the movement, the protective plate 10 will rotate in a ring around the rotating column 9. The larger size of the protective groove 11 will reduce the possibility of collision with the two ends of the electromagnetic plate 3, thus reducing the service life.

[0031] The telescopic component includes a spring 13. One end of the spring 13 is fixedly connected to the side wall of the annular groove 12. The end of the spring 13 away from the annular groove 12 is fixedly connected to a telescopic column 14. The end of the telescopic column 14 away from the spring 13 extends out of the annular groove 12 and is fixedly connected to a telescopic bracket 15. The bottom of the telescopic bracket 15 adjacent to the telescopic column 14 is fixedly connected to a telescopic block 16 that matches the cross-section of the limiting groove 7. The end of the telescopic bracket 15 away from the telescopic column 14 is fixedly connected to a tension ring 17. The tension ring 17 is arranged in a ring shape, which conforms to the ergonomic principle.

[0032] A valve seat 4 is fixedly connected to the bottom of the control board 1, and valve pipes 5 are fixedly connected to both sides of the control board 1. A material conveying hole is opened inside the control board 1, and a material inlet is opened at the bottom of the valve seat 4. The material inlet is connected to the material conveying hole.

[0033] The working principle provided by this utility model is as follows: During installation or maintenance, the protective plate 10 is in a closed state, the protective groove 11 covers the electromagnetic plate 3, the telescopic block 16 is located in the limiting groove 7 of the limiting bracket 6, and the spring 13 is in a natural state. The operator applies a tensioning force to the tension ring 17 to drive the telescopic bracket 15 to move, thereby pulling the telescopic column 14 and the telescopic block 16. The telescopic column 14 stretches the spring 13, causing the telescopic block 16 to disengage from the limiting groove 7 of the limiting bracket 6. After the telescopic block 16 disengages from the limiting groove 7, the protective plate 10 can rotate around the rotating column 9 as the axis. During the rotation of the protective plate 10, the protective groove 11 at the bottom gradually separates from the electromagnetic plate 3, exposing the electromagnetic plate 3 for operation or maintenance. At this time, the operator can perform operations such as inspection, repair or replacement of the electromagnetic plate 3.

[0034] After closing the protective plate 10 for protection, and completing the operation of the electromagnetic plate 3, the protective plate 10 needs to be closed again to protect the electromagnetic plate 3 from the influence of the external environment. Rotate the rotating column 9 again to make the protective groove 11 of the protective plate 10 gradually approach the electromagnetic plate 3. Before the protective groove 11 is about to contact the electromagnetic plate 3, the operator needs to stretch the telescopic bracket 15 again so that the position of the telescopic block 16 is outside the limit bracket 6. When the telescopic block 16 is flush with the limit groove 7 of the limit bracket 6, the stretching of the telescopic bracket 15 is released. Using the elastic potential energy of the spring 13, the telescopic column 14 and the telescopic block 16 automatically reset, so that the telescopic block 16 is tightly attached to the inner wall of the limit groove 7, ensuring that the protective plate 10 is stably covering the electromagnetic plate 3.
