Description

Technical Field

[0001] This utility model relates to the field of coal mine backfilling and mining technology, specifically to a hydraulic lifting and isolation device for paste backfilling space. Background Technology

[0002] In coal mining, horizontal shaft tunneling machines are commonly used for coal mining operations. During the mining process, hydraulic supports are used to support the roadway of the mining face. As the horizontal shaft tunneling machine advances, the hydraulic supports need to be pushed and pulled in sequence. Behind the hydraulic supports, a goaf filling space is formed. To prevent the ground above the goaf filling space from settling, the goaf filling space needs to be filled with paste and gangue. To ensure the filling effect of the goaf filling space, the goaf filling space is usually filled with paste in a segmented and isolated manner.

[0003] Existing technologies typically employ isolation walls to segment and isolate goaf-filling spaces. These walls are generally constructed primarily of single pillars, bamboo mats, and wooden planks, making them unsuitable for isolating goaf-filling spaces with large mining heights and steep inclinations. They also exhibit weak compressive and tensile strength, making them ill-suited for goaf-filling spaces of varying heights and inclinations. Furthermore, the construction and installation of these isolation walls often require significant manpower and resources, resulting in high labor intensity for workers, poor reliability, inconvenient operation, and difficulty in adapting to diverse application scenarios. Summary of the Invention

[0004] This utility model addresses the problem that existing isolation walls are difficult to adapt to mined-out filling spaces of different heights and inclination angles by providing a hydraulic lifting isolation device for paste filling spaces. The device itself is height-adjustable, enabling it to meet the isolation requirements of mined-out filling spaces of different heights and inclination angles. It is also easy to assemble, disassemble, and move, reducing the labor intensity of workers.

[0005] To achieve the above objectives, the technical solution of this utility model is: a hydraulic lifting and isolating device for a paste filling space, comprising at least one isolation structure, wherein the isolation structure includes two hydraulic lifting and isolating mechanisms arranged opposite each other, and a connecting component is provided between the two hydraulic lifting and isolating mechanisms. The isolation structure segments the mined-out filling space, and the connecting component connects the two opposite hydraulic lifting and isolating mechanisms to form the isolation structure, thereby achieving the effect of segmenting and isolating the mined-out filling space using the two hydraulic lifting and isolating mechanisms.

[0006] The hydraulic lifting and isolation mechanism includes a base, a support base, an isolation baffle, and a lifting assembly. The support base is located above the base, and the isolation baffle is installed on the outer side of the support base. The isolation baffle consists of multiple isolation plates, which are spliced ​​together to form the isolation baffle. The isolation baffle seals and isolates the mined-out filling space. The lifting assembly drives the support base to move up and down, and the support base synchronously drives the isolation baffle to move up and down, achieving the effect of segmented isolation of mined-out filling spaces at different heights.

[0007] The lifting components are spaced apart between the base and the support, with both ends of each lifting component connected to the base and the support, respectively. A fixing component is provided between adjacent lifting components and is connected to the lifting component. The fixing component secures the lifting component, ensuring stability and safety during use.

[0008] Furthermore, the lower inner side of the isolation plate is symmetrically provided with baffle connecting seats, and the upper inner side of the isolation plate is symmetrically provided with strip connecting plates. The baffle connecting seats and strip connecting plates on two adjacent isolation plates are hinged together; the uppermost isolation plate is connected to the support base. Two adjacent isolation plates are connected by baffle connecting seats and strip connecting plates to facilitate the assembly and disassembly of the isolation plates, and to facilitate the addition or removal of isolation plates according to the height of the mined-out filling space.

[0009] Furthermore, the top of the support base is symmetrically provided with convex plates, and the top of the convex plates is provided with multiple sharp blocks at intervals; a square hole is opened on the outer side plate of the base, and a sampling gate is provided at the square hole. After the support base contacts the top of the goaf filling space, the sharp blocks can be inserted into the top of the goaf filling space, improving the stability of the device.

[0010] Furthermore, the lifting assembly includes a column and a lifting cylinder. The lower end of the column is connected to the base via a pin, and the upper end of the column is equipped with a clamp. The lifting cylinder is fixedly mounted on the top of the column, and the piston rod of the lifting cylinder is connected to a support seat. The column supports the lifting cylinder and ensures that the lifting cylinder can lift the support seat to the top of the mined-out filling space.

[0011] Furthermore, the fixing assembly includes a support plate, a connecting seat, and a fixing member. The lower end of the support plate is connected to the inner side plate of the base. The connecting seat is disposed inside the support plate. Side fixing plates are symmetrically arranged on both sides of the lower part of the connecting seat. A limiting plate is provided at the bottom of the side fixing plate, and one end of the limiting plate is located at the top of the inner side plate of the base. The limiting plate serves to limit the support plate and prevent the support plate from tilting to either side. The side fixing plate ensures that one end of the limiting plate is located at the top of the inner side plate of the base, thus ensuring that the limiting plate effectively limits the support plate.

[0012] Furthermore, both sides of the connecting seat are provided with fixing components, which include multiple arc-shaped connecting plates, hand gripping plates, and fastening arc plates. The arc-shaped connecting plates are fixedly connected to the connecting seat, and both ends of the arc-shaped connecting plates are connected to the hand gripping plates via pins. The hand gripping plates are fixedly connected to the fastening arc plates, and the fastening arc plates are connected to the clamp bolts. The cooperation between the hand gripping plates and the arc-shaped connecting plates facilitates the opening and closing of the two fastening arc plates. The two fastening arc plates, in conjunction with the clamp, achieve the effect of fixing the column.

[0013] Furthermore, the base is symmetrically provided with mounting seats inside, and both the mounting seats and the connecting seats are provided with connecting members at their tops. The connecting members include a sleeve and a fixed shaft sleeved inside the sleeve.

[0014] Furthermore, the connecting assembly includes three horizontal cylinders: a first horizontal cylinder, a second horizontal cylinder, and a third horizontal cylinder. There are two first horizontal cylinders, each with its two ends connected to a fixed shaft on the top of one of the two mounting bases. Similarly, the two ends of the second horizontal cylinder are also connected to fixed shafts on the top of one of the two connecting bases. The first, second, and third horizontal cylinders connect two corresponding hydraulic lifting and isolating mechanisms to ensure the stability and safety of the device during use, and also allow for adjustment of the distance between the two hydraulic lifting and isolating mechanisms.

[0015] Furthermore, a hinge seat is provided at the center of the inner side of the support base, and both ends of the transverse hydraulic cylinder three are respectively hinged to two corresponding hinge seats. The transverse hydraulic cylinder three connects two corresponding support bases through the hinge seats to improve the stability of the top of the support base to the mined-out filling space.

[0016] Furthermore, a connecting mechanism is provided on the inner side of the two hydraulic lifting isolation mechanisms arranged side by side. The connecting mechanism includes a longitudinal oil cylinder and two inner bases. The two inner bases are respectively arranged inside the base of the two hydraulic lifting isolation mechanisms. A connecting piece is also provided on the top of the inner base. The two ends of the longitudinal oil cylinder are respectively connected to the connecting pieces on the top of the two inner bases. The connecting mechanism serves to connect the two adjacent isolation structures and improve the stability of the device structure.

[0017] The beneficial effects of this utility model through the above technical solution are as follows:

[0018] This utility model has a reasonable structure and good performance. Its height can be adjusted to meet the isolation needs of mined-out filling spaces at different heights. It can be placed on the inclined surface of mined-out filling spaces at different angles to meet the isolation needs of mined-out filling spaces at different angles. It can adapt to the isolation of mined-out filling spaces with large mining height and large angle. It does not require a lot of manpower and material resources, thus reducing the labor intensity of workers.

[0019] This utility model's isolation structure achieves the effect of segmented isolation of the mined-out filling space through two corresponding hydraulic lifting isolation mechanisms. The isolation baffle of the hydraulic lifting isolation mechanism seals and isolates the mined-out filling space. The lifting component drives the isolation baffle to move up and down, which can adjust the height of the isolation baffle to meet the isolation requirements of mined-out filling spaces at different heights. The fixing component fixes the lifting component, ensuring stability and safety during use.

[0020] The two hydraulic lifting isolation mechanisms of this utility model are connected by a connecting component, which improves the stability and safety of the isolation structure and allows for adjustment of the distance between the two hydraulic lifting isolation mechanisms. The column of the lifting component supports the lifting cylinder, ensuring that the lifting cylinder pushes the support seat to the top of the goaf filling space, thereby ensuring that the isolation baffle seals and isolates the goaf filling space. After the support seat contacts the top of the goaf filling space, the sharp block on the convex block on the top of the support seat can be inserted into the top of the goaf filling space, improving the stability of the isolation structure when isolating the goaf filling space.

[0021] This utility model of isolation baffle is composed of multiple isolation plates spliced ​​together. Through the function of baffle connecting seats and strip connecting plates on the isolation plates, it is easy to disassemble and install the isolation plates. The number of isolation plates can be increased or decreased according to the height of the mined-out filling space to be blocked and isolated.

[0022] The two adjacent isolation structures of this utility model are connected by a connecting mechanism, which plays a role in stabilizing and strengthening the isolation structures, thereby improving the stability of the device structure. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0034] like Figures 1-9 As shown, a hydraulic lifting and isolating device for a paste filling space includes at least one isolation structure. Each isolation structure comprises two opposing hydraulic lifting and isolating mechanisms, with a connecting component between the two mechanisms. In this embodiment, two isolation structures are arranged side-by-side. By placing the isolation structures within the goaf filling space, the space is segmented and isolated. The connecting component connects the two corresponding hydraulic lifting and isolating mechanisms, which effectively segment and isolate the goaf filling space.

[0035] The hydraulic lifting isolation mechanism includes a base 1, a support base 13, an isolation baffle, and a lifting assembly. The support base 13 is located above the base 1, and the isolation baffle is provided on the outer side of the support base 13. The isolation baffle includes multiple isolation plates 17, which are spliced ​​together to form the isolation baffle. In this embodiment, the base 1 has a hollow interior and an open top. The base 1 allows the hydraulic lifting isolation mechanism to be placed on the inclined surface of the goaf filling space, achieving an effect suitable for isolation requirements of goaf filling spaces with different inclination angles. The isolation baffle serves to isolate the goaf filling space.

[0036] The lifting components are arranged at intervals between the base 1 and the support 13. Both ends of the lifting components are connected to the base 1 and the support 13, respectively. A fixing component is provided between two adjacent lifting components, and the fixing component is connected to the lifting component. In this embodiment, there are two lifting components between the base 1 and the support 13. The lifting components can drive the support 13 to move up and down. Simultaneously, the support 13 moves up and down, driving the isolation baffle to move up and down. When the lifting components push the support 13 to the top of the goaf filling space, the isolation baffle isolates the goaf filling space.

[0037] The lower inner side of the isolation plate 17 is symmetrically provided with baffle connecting seats 18, and the upper inner side of the isolation plate 17 is symmetrically provided with strip connecting plates 19. The baffle connecting seats 18 and strip connecting plates 19 on two adjacent isolation plates 17 are hinged together; the uppermost isolation plate 17 is connected to the support base 13. In this embodiment, there are two baffle connecting seats 18 and two strip connecting plates 19 on the inner side of the isolation plate 17. The baffle connecting seats 18 and the strip connecting plates 19 correspond to each other vertically. The baffle connecting seat 18 includes two strip plates that are fixedly connected to the isolation plate 17. The two strip plates are fitted with pins. The upper end of the strip connecting plate 19 has a through hole. The strip connecting plate 19 is fitted onto the pin through the through hole. Two adjacent isolation plates 17 are connected to each other through the pin of the baffle connecting seat 18 and the strip connecting plate 19. The inner side of the uppermost isolation plate 17 is not fitted with a strip connecting plate 19. The uppermost isolation plate 17 has symmetrical pin holes on its upper side. The outer side of the support base 13 is symmetrically fitted with pin shafts. The uppermost isolation plate 17 is connected to the support base 13 through the pin holes and the pin shafts. The two lowermost isolation plates 17 can be folded. The isolation baffle is composed of multiple isolation plates 17 spliced ​​together. The number of isolation plates 17 can be increased or decreased according to the height of the mined-out filling space.

[0038] The top of the support base 13 is symmetrically provided with convex plates 14, and the top of the convex plates 14 is provided with a plurality of sharp blocks 15 spaced apart. The outer side plate of the base 1 has a square hole, and a sampling door 26 is provided at the square hole. In this embodiment, there are two convex plates 14 on the top of the support base 13, and three sharp blocks 15 on the convex plates 14. The height of the sharp block 15 located in the middle is higher than the height of the sharp blocks 15 on both sides. The purpose of this is that when the support base 13 is in close contact with the top of the goaf filling space, the sharp block 15 can be inserted into the top of the goaf filling space, thereby improving the stability of the hydraulic lifting isolation mechanism. The upper end of the sampling door 26 is hinged to the outer side plate of the base 1. After the space is filled with paste in the segmented isolation by the hydraulic lifting isolation mechanism for a period of time, the sampling door 26 can be opened to drain the water that has seeped into the isolation baffle side of the paste. The paste sample can also be taken from the sampling door 26 and the state of paste solidification can be observed.

[0039] The lifting assembly includes a column 3 and a lifting cylinder 12. The lower end of the column 3 is connected to the base 1 via a pin, and the upper end of the column 3 is provided with a clamp 4. The lifting cylinder 12 is fixedly installed on the top of the column 3, and the piston rod of the lifting cylinder 12 is connected to a support seat 13. In this embodiment, the column 3 supports the lifting cylinder 12 to ensure that the lifting cylinder 12 can lift the support seat 13 to the top of the mined-out filling space. A pin is fixedly installed inside the support seat 13, and the end of the piston rod of the lifting cylinder 12 is rotatably fitted onto the pin.

[0040] The fixing assembly includes a support plate 5, a connecting seat 6, and a fixing member. The lower end of the support plate 5 is connected to the inner side plate of the base 1. The connecting seat 6 is disposed on the inner side of the support plate 5. Side fixing plates 20 are symmetrically arranged on both sides of the lower part of the connecting seat 6. A limiting plate 21 is provided at the bottom of the side fixing plate 20. One end of the limiting plate 21 is located at the top of the inner side plate of the base 1. In this embodiment, the inner side plate of the base 1 has an inverted "T" shape. A pin is installed at the upper end of the inner side plate of the base 1, and the support plate 5 is fitted on the pin. The limiting plate 21 limits the support plate 5 to prevent the support plate 5 from tilting to both sides. The side fixing plate 20 makes one end of the limiting plate 21 located at the top of the inner side plate of the base 1 to ensure that the limiting plate 21 limits the support plate 5. The side fixing plate 20 and the limiting plate 21 are both provided with arc-shaped grooves that match the column 3 on the side near the column 3. The purpose of this is to avoid interference between the side fixing plate 20 and the limiting plate 21 and the column 3.

[0041] The fasteners are provided on both sides of the connecting seat 6. Each fastener includes multiple arc-shaped connecting plates 7, gripping plates 8, and fastening arc plates 9. The arc-shaped connecting plates 7 are fixedly connected to the connecting seat 6. Both ends of the arc-shaped connecting plates 7 are connected to the gripping plates 8 via pins. The gripping plates 8 are fixedly connected to the fastening arc plates 9, which are bolted to the clamp 4. In this embodiment, the fasteners include three arc-shaped connecting plates 7, which are spaced apart on the connecting seat 6. Pins are vertically installed at both ends of each arc-shaped connecting plate 7. A gripping plate 8 is installed between adjacent arc-shaped connecting plates 7. The gripping plate 8 is rotatably mounted on the pin, allowing the gripping plate 8 to drive the fastening arc plate 9 to open and close, thus loosening or tightening the pins of the column 3. The fastening arc plate 9 includes an arc-shaped portion matching the clamp 4 and a vertical portion bolted to the clamp 4.

[0042] The base 1 has symmetrically arranged mounting seats 27 inside. Both the mounting seats 27 and the connecting seat 6 have connecting members at their tops. Each connecting member includes a sleeve 10 and a fixed shaft 11 fitted inside the sleeve 10. In this embodiment, a circular plate is fixedly installed at the upper end of the fixed shaft 11, serving as a limiting element. Pins are inserted into the lower ends of the sleeve 10 and the fixed shaft 11, fixing the fixed shaft 11 within the sleeve 10 via the pins.

[0043] The connecting assembly includes a first transverse hydraulic cylinder 22, a second transverse hydraulic cylinder 23, and a third transverse hydraulic cylinder 24. There are two first transverse hydraulic cylinders 22, each with its two ends connected to a fixed shaft 11 at the top of one of the two mounting seats 27. The two ends of the second transverse hydraulic cylinder 23 are connected to fixed shafts 11 at the top of one of the two connecting seats 6. In this embodiment, both ends of the first transverse hydraulic cylinder 22 are rotatably connected to rotating seats via pins. Ear plates are mounted on the rotating seats and rotatably mounted on the fixed shafts 11. The first transverse hydraulic cylinder 22 connects to the bases 1 of the two hydraulic lifting isolation mechanisms to improve the stability of the lower part of the isolation structure. Both ends of the second transverse hydraulic cylinder 23 are rotatably connected to rotating seats via pins. Ear plates are mounted on the rotating seats and rotatably mounted on the fixed shafts 11. The second transverse hydraulic cylinder 23 connects to the connecting seats 6 of the two hydraulic lifting isolation mechanisms to improve the stability of the middle part of the isolation structure.

[0044] A hinge seat 16 is provided at the inner center of the support base 13, and the two ends of the transverse hydraulic cylinder 24 are respectively hinged to two corresponding hinge seats 16. In this embodiment, the transverse hydraulic cylinder 24 connects two corresponding support bases 13 through the hinge seats 16 to improve the stability of the top of the support base 13 to the mined-out filling space, that is, to improve the stability of the upper part of the isolation structure.

[0045] The inner sides of the two hydraulic lifting isolation mechanisms arranged side by side are provided with a connecting mechanism, which includes a longitudinal cylinder 25 and two inner bases 2. The two inner bases 2 are respectively located inside the bases 1 of the two hydraulic lifting isolation mechanisms. The top of each inner base 2 is also provided with a connecting piece. The two ends of the longitudinal cylinder 25 are respectively connected to the connecting pieces at the top of the two inner bases 2. In this embodiment, the two ends of the longitudinal cylinder 25 are also rotatably connected to a rotating seat via a pin. The rotating seat is equipped with an ear plate, which is rotatably fitted onto a fixed shaft 11. The inner bases 2 inside the bases 1 of the two hydraulic lifting isolation mechanisms are connected by a transverse cylinder 22 to improve the stability of the two adjacent isolation structures. The number of isolation structures can be selected according to the width of the mined-out filling space.

[0046] The working principle of this utility model is as follows: When the horizontal shaft tunneling machine pushes and pulls the hydraulic support during tunneling, a goaf filling space is formed in the space behind the hydraulic support. When the goaf filling space needs to be filled, a specified number of hydraulic lifting isolation devices are placed in the goaf filling space according to the length of the goaf filling space and the length of the section to be isolated. The base 1 of the hydraulic lifting isolation mechanism is placed on the inclined surface of the goaf filling space, which is suitable for goaf filling spaces with different inclination angles.

[0047] After the hydraulic lifting isolation device is placed, the lifting cylinder 12 is opened, the piston rod of the lifting cylinder 12 extends and drives the support seat 13 to move upward. The support seat 13 drives the isolation baffle to move upward. After the support seat 13 is in close contact with the top of the goaf filling space and the sharp block 15 is inserted into the top of the goaf filling space, the lifting cylinder 12 is closed. At this time, the isolation baffle achieves the purpose of sealing and isolating the goaf filling space. Then, the segmented isolated goaf filling space can be filled with paste.

[0048] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model.
