Technical Field

[0001] This utility model relates to the field of electro-hydraulic control transmission technology, and in particular to an adaptive electro-hydraulic control transmission component. Background Technology

[0002] Hydraulic systems, with their high power density, rapid response, and large load capacity, have become a core driving technology in fields such as engineering machinery and aerospace since the mid-20th century. For example, hydraulic supports play a crucial role in supporting the roof in fully mechanized coal mining faces, and their stability directly affects production safety. Traditional hydraulic systems rely on mechanical valve groups and fixed parameter control.

[0003] Most electro-hydraulic control transmission components on the market are monolithic, and the length of the telescopic end body is fixed, which cannot meet the length requirements. Therefore, an adaptive electro-hydraulic control transmission component is needed. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive electro-hydraulic control transmission assembly, which solves the problem that most existing electro-hydraulic control transmission assemblies are monolithic, while the length of the telescopic end body is fixed, which makes it impossible to meet the length requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptively adjustable electro-hydraulic control transmission assembly, comprising an electro-hydraulic control transmission body, a hydraulic push rod at the telescopic end of the electro-hydraulic control transmission body, an adjusting push rod at the top end of the hydraulic push rod, a first bearing on the side wall of the adjusting push rod, a hand handle on the inner side of the first bearing, a first bevel gear fixed at the end of the hand handle, a second bevel gear meshing with one side of the first bevel gear, a threaded column fixed on the inner side of the second bevel gear, a second bearing on the outer side of the top end of the threaded column, a first threaded groove threadedly connected to the outer periphery of the threaded column, an adjusting bracket installed outside the first threaded groove, a slider fixed on the side wall of the adjusting bracket, and a slide rail on the outer side of the slider.

[0006] Preferably, the upper wall of the electro-hydraulic control transmission body is provided with an oil drain port, the inner side of the oil drain port is provided with a closing cover, and a gel sealing ring is provided at the connection between the oil drain port and the closing cover.

[0007] Preferably, the hand handle forms a rotating structure with the adjusting rod via the first bearing, and the hand handle forms a fixed structure with the first bevel gear. The first bevel gear forms a meshing structure with the threaded column via the second bevel gear.

[0008] Preferably, the threaded column is threadedly connected to the adjusting bracket via a first threaded groove, and the adjusting bracket is slidingly connected to the slide rail via a slider.

[0009] Preferably, the side wall of the oil drain port is provided with a rotating shaft, the periphery of the rotating shaft is provided with a locking plate, the side wall of the locking plate is fixed with a handle, the other side wall of the locking plate is fixed with a limiting plate, the outer wall of the closing cover is provided with a limiting groove, one side of the limiting groove is provided with a locking groove, the locking plate and the oil drain port form a rotating structure through the rotating shaft, the handle and the limiting plate form a fixed structure through the locking plate and the limiting plate, the locking plate and the closing cover form a locking structure through the locking groove, and the limiting plate and the closing cover form a sliding structure through the limiting groove.

[0010] Preferably, a retaining ring is provided on the outer side of the handle, and a second threaded groove is provided at the connection between the retaining ring and the handle, and the retaining ring is threadedly connected to the handle through the second threaded groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The adaptive electro-hydraulic control transmission assembly is equipped with a threaded column and a first threaded groove. By rotating the hand handle with external force, the first bevel gear can be rotated. Through the meshing structure of the first and second bevel gears, the rotation of the first bevel gear can cause the second bevel gear to rotate, which indirectly drives the threaded column to rotate. Then, through the threaded connection between the threaded column and the first threaded groove, the rotation of the threaded column can cause the adjusting bracket to move. The movement of the adjusting bracket can push the adjusting rod in the opposite direction to move and extend, thereby adjusting the length of the telescopic end body. This avoids the situation where most of the electro-hydraulic control transmission assembly is a single piece, while the length of the telescopic end body is fixed, which would prevent the length requirement from being met. 2. The adaptive electro-hydraulic control transmission assembly is equipped with a locking plate and a limiting plate. When the handle is in the open state, the limiting plate will be located at the innermost side of the drain port. Through the sliding structure of the limiting plate and the limiting groove, the closing cover can be installed inside the drain port. Then, by rotating the handle with external force, the locking plate and the limiting plate can be rotated, so that the locking plate is engaged with the locking groove to install the closing cover. Since the width of the locking plate is greater than the limiting groove, the closing cover cannot slide out. Finally, the fixing ring is installed through the second threaded groove to fix the handle and realize the quick disassembly and assembly of the closing cover, so that the oil can be dispensed or discharged after the closing cover is quickly disassembled and assembled.

A hydraulic push rod 2 is provided at the telescopic end of the electro-hydraulic control transmission body 1. An adjusting push rod 3 is provided at the top of the hydraulic push rod 2. A first bearing 4 is provided on the side wall of the adjusting push rod 3. A hand handle 5 is provided on the inner side of the first bearing 4. A first bevel gear 6 is fixed at the end of the hand handle 5. A second bevel gear 7 is meshed with one side of the first bevel gear 6. A threaded column 8 is fixed on the inner side of the second bevel gear 7. A second bearing 9 is provided on the outer side of the top of the threaded column 8. A first threaded groove 10 is threadedly connected to the outer periphery of the threaded column 8. An adjusting bracket 11 is installed on the outside of the first threaded groove 10. A slider 12 is fixed on the side wall of the adjusting bracket 11. A slide rail 13 is provided on the outer side of the slider 12.

[0016] The hand crank 5 forms a rotating structure with the adjusting rod 3 via the first bearing 4. The hand crank 5 forms a fixed structure with the first bevel gear 6. The first bevel gear 6 forms a meshing structure with the threaded column 8 via the second bevel gear 7. When the hand crank 5 is rotated by external force, the first bevel gear 6 can be driven to rotate. Through the meshing structure of the first bevel gear 6 and the second bevel gear 7, the rotation of the first bevel gear 6 can cause the second bevel gear 7 to rotate, which indirectly drives the threaded column 8 to rotate.

[0017] The threaded column 8 is connected to the adjusting bracket 11 by the first threaded groove 10. The adjusting bracket 11 is connected to the slide rail 13 by the slider 12. Through the threaded connection between the threaded column 8 and the first threaded groove 10, the rotation of the threaded column 8 can move the adjusting bracket 11. The movement of the adjusting bracket 11 can push the adjusting rod 3 in the opposite direction to move and extend, thereby adjusting the length of the telescopic end body.

[0018] Example 2 Unlike Embodiment 1, the upper wall of the electro-hydraulic control transmission body 1 is provided with an oil drain port 14, and a closing cover 15 is provided on the inner side of the oil drain port 14. A colloid sealing ring 16 is provided at the connection between the oil drain port 14 and the closing cover 15. The colloid sealing ring 16 can make the closing cover 15 have a certain degree of sealing after installation.

[0019] Example 3 Unlike Embodiment 1, the side wall of the drain port 14 is provided with a rotating shaft 17, and a locking plate 18 is provided around the rotating shaft 17. A handle 19 is fixed to the side wall of the locking plate 18, and a limiting plate 20 is fixed to the other side wall of the locking plate 18. A limiting groove 21 is formed on the outer wall of the closing cover 15, and a locking groove 22 is provided on one side of the limiting groove 21. The locking plate 18 and the drain port 14 form a rotating structure through the rotating shaft 17. The handle 19 and the limiting plate 20 form a fixed structure through the locking plate 18 and the limiting plate 20. The locking plate 18 and the closing cover 15 form a locking structure through the locking groove 22. The limiting plate 20 and the closing cover form a locking structure through the limiting groove 21. 15 forms a sliding structure. When the handle 19 is in the open state, the limiting plate 20 will be located at the innermost side of the oil drain port 14. Through the sliding structure of the limiting plate 20 and the limiting groove 21, the closing cover 15 can be installed inside the oil drain port 14. Then, by rotating the handle 19 with external force, the locking plate 18 and the limiting plate 20 can be rotated, so that the locking plate 18 is locked into the locking groove 22 to install the closing cover 15. Since the width of the locking plate 18 is greater than that of the limiting groove 21, the closing cover 15 cannot slide out, realizing the quick installation and removal of the closing cover 15, so that the oil can be taken out and discharged after the closing cover 15 is quickly installed and removed.

[0020] A retaining ring 24 is provided on the outer side of the handle 19. A second threaded groove 23 is provided at the connection between the retaining ring 24 and the handle 19. The retaining ring 24 is threadedly connected to the handle 19 through the second threaded groove 23. The retaining ring 24 is installed through the second threaded groove 23 to fix the handle 19.

[0021] Working principle: First, by rotating the hand handle 5 with external force, the first bevel gear 6 can be rotated. The rotation of the first bevel gear 6 can rotate the second bevel gear 7, which indirectly drives the threaded column 8 to rotate. The rotation of the threaded column 8 can move the adjusting bracket 11. The movement of the adjusting bracket 11 can push the adjusting rod 3 in the opposite direction to move and extend, thereby adjusting the length of the telescopic end body. Then, when the hand handle 19 is in the open state, the limiting plate 20 will be located at the oil drain port 1. On the innermost side of 4, through the sliding structure of the limiting plate 20 and the limiting groove 21, the closing cover 15 can be installed inside the oil drain port 14. Then, by rotating the handle 19 with external force, the locking plate 18 and the limiting plate 20 can be rotated, so that the locking plate 18 is locked into the locking groove 22 to install the closing cover 15. Since the width of the locking plate 18 is greater than that of the limiting groove 21, the closing cover 15 cannot slide out, realizing the quick installation and removal of the closing cover 15, so that the oil can be removed and discharged after the closing cover 15 is quickly installed and removed.
