Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, and in particular to a hydraulic support maintenance device. Background Technology

[0002] Hydraulic supports are the core support equipment for modern fully mechanized mining faces. Their core function is to create a safe and movable steel structure working space for underground coal mining operations. By providing stable and reliable roof support, they effectively isolate the goaf and fundamentally ensure the safety of personnel and equipment, which is the fundamental guarantee for safe production in mines.

[0003] Commonly used hydraulic support maintenance equipment is difficult to support and position large components of hydraulic supports. Furthermore, due to the large weight of the hydraulic support components, they are not easy to rotate on the maintenance equipment, making it difficult to align the components with the hydraulic support. This requires the use of a hand-operated hoist or crane for positioning, resulting in a high level of maintenance difficulty. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a hydraulic support repair device, which aims to improve the problem that commonly used hydraulic support repair devices are difficult to support and position large components of hydraulic supports. Furthermore, due to the large weight of the hydraulic support components, they are not easy to rotate on the repair device, which makes it difficult to align the components with the hydraulic support. This requires the use of a hand hoist or crane for positioning, resulting in high repair difficulty.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic support maintenance device, comprising a base plate, a scissor mechanism and a hydraulic mechanism fixedly connected to the top surface of the base plate, the hydraulic mechanism being rotatably connected to the middle of the scissor mechanism, a top plate fixedly connected to the top surface of the scissor mechanism, a fixing ring fixedly connected to the top surface of the top plate by bolts, a rotating ring rotatably connected to the inner wall of the fixing ring by ball bearings, an adjusting plate fixedly connected to the top surface of the rotating ring, and a limit block fixedly connected to the top surface of the adjusting plate.

[0006] By adopting the above solution, a slewing bearing is constructed by using a top plate and bolts to install a fixing ring, and then using the fixing ring and ball bearings to install a slewing ring. An adjusting plate is then installed on the slewing ring, and a limit block is installed on the adjusting plate. This limits the movement of the hydraulic support components and allows them to rotate horizontally. This improves the problem that commonly used hydraulic support maintenance devices are unable to support and position large components of the hydraulic support. Furthermore, because the components of the hydraulic support are heavy, they are not easy to rotate on the maintenance device, making it difficult to align the components with the hydraulic support. This requires the use of a hand-operated hoist or crane for positioning, resulting in high maintenance difficulty.

[0007] Preferably, the scissor lift mechanism includes a second mounting bracket, the second mounting bracket being rotatably connected to a first scissor lift arm via a mounting shaft, a third sliding block being fixedly connected to the bottom surface of the top plate, and a second slider being slidably connected inside the two third sliding blocks, the end of the first scissor lift arm away from the second mounting bracket being fixedly connected to the second slider, the bottom surface of the top plate being fixedly connected to a third mounting bracket, the third mounting bracket being rotatably connected to a second scissor lift arm via a mounting shaft, the top surface of the bottom plate being fixedly connected to a first sliding block and a second sliding block, the interior of the first and second sliding blocks being slidably connected to a first slider, the end of the second scissor lift arm away from the third mounting bracket being fixedly connected to the first slider, and the first scissor lift arm being rotatably connected to the second scissor lift arm via a central pin.

[0008] Preferably, the hydraulic mechanism includes a first mounting bracket, a first hydraulic cylinder is rotatably connected to the first mounting bracket via a mounting shaft, a first piston rod is slidably connected to the inner wall of the first hydraulic cylinder, a first connecting column is fixedly connected to the end of the first piston rod away from the first hydraulic cylinder, a connecting piece is rotatably connected to the end of the first connecting column, a second connecting column is rotatably connected to the end of the connecting piece away from the first connecting column, and the second connecting column is rotatably connected to the side of the second scissor arm near the third mounting bracket.

[0009] Preferably, a fixing block is fixedly connected to the top surface of the top plate, a second hydraulic cylinder is fixedly connected to the top surface of the fixing block, and a second piston rod is slidably connected to the inner wall of the second hydraulic cylinder.

[0010] Preferably, an adjusting cylinder is fixedly connected to the side wall of the limiting block, and an adjusting rod is provided on the inner wall of the adjusting cylinder.

[0011] Preferably, a wheel frame is fixedly connected to the bottom surface of the base plate, and the wheel frame is rotatably connected to wheels via axles.

[0012] Preferably, the wheel has a pin hole inside, and a pin is slidably connected in the pin hole, the pin passing through the side wall of the wheel frame.

[0013] Preferably, a handle is fixedly connected to the end of the base plate.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a fixed ring is installed using a top plate and bolts, and a slewing ring is installed using the fixed ring and ball bearings, thus forming a slewing bearing. An adjusting plate is then installed using the slewing ring, and a limiting block is installed on the adjusting plate. This limits the movement of the hydraulic support components and allows them to rotate horizontally. This improves upon the common problem that hydraulic support maintenance devices struggle to support and position large hydraulic support components. Furthermore, because the hydraulic support components are heavy, they are difficult to rotate on maintenance devices, making it difficult to align the components with the hydraulic support. This necessitates the use of a hand-operated hoist or crane for positioning, leading to significant maintenance difficulties.

[0015] 2. In this utility model, a first scissor arm is installed on the base plate, a second scissor arm is installed on the top plate, and a third sliding block limits the second slider. A first sliding block and a second sliding block limit the first slider. A central pin connects the first and second scissor arms. A first hydraulic cylinder and a first piston rod work in conjunction with a second connecting column to provide power to the second scissor arm, thereby driving the first and second scissor arms to rise, thus raising the top plate. This improves the problem of unstable lifting and insufficient lifting force in common hydraulic support maintenance devices, which increases the risk of hydraulic support parts and maintenance personnel falling.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-3 One embodiment of this utility model provides a hydraulic support maintenance device, including a base plate 1. A scissor mechanism and a hydraulic mechanism are fixedly connected to the top surface of the base plate 1. The hydraulic mechanism is rotatably connected to the middle of the scissor mechanism. A top plate 25 is fixedly connected to the top surface of the scissor mechanism. A fixing ring 26 is fixedly connected to the top surface of the top plate 25 by bolts 27. A rotating ring 29 is rotatably connected to the inner wall of the fixing ring 26 by ball bearings 28. An adjusting plate 30 is fixedly connected to the top surface of the rotating ring 29. A limit block 31 is fixedly connected to the top surface of the adjusting plate 30.

[0020] Specifically, the base plate 1 is used to install the scissor mechanism and the hydraulic mechanism. The scissor mechanism is used to install the top plate 25, and the top plate 25, together with bolts 27, is used to install the fixing ring 26. The bolts 27 are used to fix the fixing ring 26 and prevent it from shaking. The fixing ring 26 can cooperate with the ball bearings 28 to install the rotating ring 29. The ball bearings 28 are spherical, which reduces the friction of the rotating ring 29 and improves its sensitivity and durability. The rotating ring 29 is used to install the adjusting plate 30 and drive the adjusting plate 30 to rotate. The adjusting plate 30 is used to install the limiting block 31 and cooperates with the limiting block 31 to limit the components of the hydraulic support, preventing the components from rolling or shaking. By rotating the adjusting plate 30, the components can be driven to rotate. The component rotates, thereby aligning with the mounting holes of the component. The fixing ring 26 is installed using the top plate 25 and bolts 27. The slewing ring 29 is installed using the fixing ring 26 and ball bearings 28, thus forming a slewing bearing. The adjusting plate 30 is then installed using the slewing ring 29, and a limit block 31 is installed on the adjusting plate 30. This limits the hydraulic support component and allows it to rotate in the horizontal direction. This improves the problem that commonly used hydraulic support maintenance devices are difficult to support and position large components of hydraulic supports. Furthermore, because the components of hydraulic supports are heavy, they are not easy to rotate on the maintenance device, making it difficult to align the components with the hydraulic support. This requires the use of a hand hoist or crane for positioning, resulting in high maintenance difficulty.

[0021] Reference Figures 1-3The scissor lift mechanism includes a second mounting bracket 12, which is rotatably connected to a first scissor lift arm 13 via a mounting shaft 9. A third sliding block 22 is fixedly connected to the bottom surface of the top plate 25. A second slider 23 is slidably connected inside the two third sliding blocks 22. The end of the first scissor lift arm 13 away from the second mounting bracket 12 is fixedly connected to the second slider 23. A third mounting bracket 24 is fixedly connected to the bottom surface of the top plate 25. A second scissor lift arm 20 is rotatably connected to the third mounting bracket 24 via a mounting shaft 9. A first sliding block 17 and a second sliding block 19 are fixedly connected to the top surface of the bottom plate 1. A first slider 18 is slidably connected inside the first sliding block 17 and the second sliding block 19. The end of the second scissor lift arm 20 away from the third mounting bracket 24 is fixedly connected to the first slider 18. The first scissor lift arm 13 is rotatably connected to the second scissor lift arm 20 via a central pin 21.

[0022] Specifically, the second mounting bracket 12 is used to install the first scissor arm 13 in conjunction with the mounting shaft 9. The first scissor arm 13 is used to install the second slider 23. The third sliding block 22 is used to limit the second slider 23 and, through the second slider 23, limit the first scissor arm 13. The third mounting bracket 24 is used to install the second scissor arm 20 in conjunction with the mounting shaft 9. The second scissor arm 20 is used to install the first slider 18 and is connected to the first scissor arm 13 through the central pin 21. The second sliding block 19 and the first sliding block 17 are used to limit the first slider 18 and, through the first slider 18, limit the second scissor arm 20. This forms a scissor lifting mechanism, improving the stability and load-bearing capacity of the top plate 25 when it rises and falls.

[0023] Reference Figure 3 The hydraulic mechanism includes a first mounting bracket 8, which is rotatably connected to a first hydraulic cylinder 10 via a mounting shaft 9. A first piston rod 11 is slidably connected to the inner wall of the first hydraulic cylinder 10. A first connecting post 14 is fixedly connected to the end of the first piston rod 11 away from the first hydraulic cylinder 10. A connecting piece 15 is rotatably connected to the end of the first connecting post 14. A second connecting post 16 is rotatably connected to the end of the connecting piece 15 away from the first connecting post 14. The second connecting post 16 is rotatably connected to the side of the second scissor arm 20 near the third mounting bracket 24.

[0024] Specifically, the first mounting bracket 8 is used to mount the first hydraulic cylinder 10 in conjunction with the mounting shaft 9. The first hydraulic cylinder 10 can provide thrust to the first piston rod 11, and then apply thrust to the connecting piece 15 and the second connecting post 16 through the first connecting post 14 connected to the first piston rod 11. Since the second connecting post 16 is fixed to the second scissor arm 20, and the second scissor arm 20 is limited by the third mounting bracket 24, the second connecting post 16 cannot move horizontally, but rotates around the first mounting bracket 8, and drives the side of the second scissor arm 20 close to the first slider 18 to slide towards the first mounting bracket 8, thereby causing the first scissor arm 13 and the second scissor arm 20 to rotate relative to each other, thereby raising the top plate 25.

[0025] Reference Figure 1 A fixing block 34 is fixedly connected to the top surface of the top plate 25, and a second hydraulic cylinder 35 is fixedly connected to the top surface of the fixing block 34. A second piston rod 36 is slidably connected to the inner wall of the second hydraulic cylinder 35.

[0026] Specifically, the fixing block 34 is used to install the second hydraulic cylinder 35 and raise the height of the second hydraulic cylinder 35 so that it is aligned with the hydraulic support parts placed on the adjusting plate 30. The second hydraulic cylinder 35 is used to install the second piston rod 36 and provide thrust to the second piston rod 36, thereby pushing the parts on the adjusting plate 30 and pushing the parts into the hydraulic support, thereby saving manpower and maintenance time.

[0027] Reference Figure 1 The side wall of the limiting block 31 is fixedly connected to an adjusting cylinder 32, and the inner wall of the adjusting cylinder 32 is provided with an adjusting rod 33.

[0028] Specifically, the adjusting cylinder 32 is used to limit the adjusting rod 33. The adjusting rod 33 is inserted into the adjusting cylinder 32, thereby driving the limiting block 31 to rotate by moving the adjusting rod 33, which in turn drives the hydraulic support to rotate. This prevents the maintenance personnel from getting their fingers pinched by directly moving the limiting block 31, and reduces the force required to rotate the adjusting plate 30, thereby reducing the manpower burden.

[0029] Reference Figures 1-4 A wheel frame 3 is fixedly connected to the bottom surface of the base plate 1, and the wheel frame 3 is rotatably connected to the wheel 5 via the wheel axle 4.

[0030] Specifically, the wheel frame 3 is used to install the wheel 5 in conjunction with the wheel axle 4. The four corners of the base plate 1 are equipped with wheel frames 3, wheel axles 4 and wheels 5, which can reduce the friction with the bottom surface and facilitate the transfer of the hydraulic support maintenance device.

[0031] Reference Figure 4 The wheel 5 has a pin hole 6 inside, and a pin 7 is slidably connected in the pin hole 6. The pin 7 passes through the side wall of the wheel frame 3.

[0032] Specifically, wheel 5 is used to open pin hole 6. Pin hole 6 can cooperate with pin 7 and wheel frame 3 to limit wheel 5. When the maintenance device is in use, pin 7 is inserted into pin hole 6 through wheel frame 3, thereby preventing the maintenance device from sliding and causing maintenance personnel and parts to fall.

[0033] Reference Figure 1 A handle 2 is fixedly connected to the end of the base plate 1.

[0034] Handle 2 is used to push the maintenance device, which speeds up the transfer of the maintenance device when needed.

[0035] Working principle: When in use, push handle 2 to stop the maintenance device below the maintenance point, and insert pin 7 into pin hole 6 through wheel bracket 3. Start the first hydraulic cylinder 10 to provide thrust to the first piston rod 11, and apply thrust to connecting piece 15 and second connecting post 16 through the first piston rod 11. Since the second connecting post 16 is fixed to the second scissor arm 20 and the second scissor arm 20 is limited by the third mounting bracket 24, the second connecting post 16 cannot be pushed horizontally, but rotates around the first mounting bracket 8, thereby driving the side of the second scissor arm 20 close to the third mounting bracket 24 to rise. The first scissor arm 13 and the second scissor arm 20 rotate relative to each other, causing the top plate 25 to rise. Place the part to be installed on the adjusting plate 30. The limiting block 31 can keep the part stable. After the top plate 25 is raised to a suitable height, insert adjusting rod 33 into adjusting cylinder 32 and turn adjusting rod 33 to align the part with the mounting port. At this time, start the second hydraulic cylinder 35 to provide thrust to the second piston rod 36, thereby pushing the part into the mounting port.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
