Description

Technical Field

[0001] The invention relates to the technical field of filling and management of goaf areas, in particular to a filling and management device for goaf areas in coal mines. Background Art

[0002] Coal mine goaf refers to the empty space or cavity left after underground coal or coal gangue is mined during coal mining operations. If the goaf is not properly reinforced or backfilled, it may collapse over time, causing ground subsidence, forming sinkholes on the surface, and possibly forming waterlogging, which in turn affects the cultivation of farmland.

[0003] The filling method is currently a common goaf management technology. Through grouting, backfilling and other methods, the voids can be filled to make the goaf reach a stable state. However, before backfilling, support members are usually set in the goaf to support the goaf. The presence of the support members will hinder the filling process. During filling, the support members need to be removed from the goaf, which is more troublesome. After the support members are removed, the goaf has no effective support during filling and is prone to collapse, posing certain safety hazards.

[0004] For example, a filling device for coal mine goaf disclosed in a Chinese patent (authorization announcement number CN109555557A) can make a side plate one against the side of the goaf to avoid collapse by rotating a rotating rod one with a rotating shaft one, and the horizontal length of the rotating rod one can be adjusted by connecting with a fixed rod one, so as to facilitate the use of goafs of different widths and increase the use range of the device. The purpose of setting the connecting rod is to enable the device to adjust the overall use height through the snap connection of the column, thereby improving the applicability of the device.

[0005] However, the device can only support the goaf, and the device located in the goaf blocks the filling of the goaf with gangue paste. When the goaf is filled with gangue paste, the entire device must be moved out of the goaf for filling. The goaf cannot be supported when the gangue paste is filled, and the goaf is prone to collapse, posing certain safety hazards.

[0006] Therefore, those skilled in the art provide a coal mine goaf filling and management device to solve the problems raised in the above background technology. Summary of the invention

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The auxiliary adjustment assembly of the present invention can be used to adjust the position of the moving box when in use. The combination of the first electric push rod and the connecting rod can make the first electric push rod drive the two connecting rods to move, and the moving box and the moving support plate can be driven to move by the movement of the connecting rod. At the same time, the connecting rod can be moved along the track of the notch under the limit of the notch through the notch provided on the inner wall of the fixed box, so that the connecting rod drives the moving box and the moving support plate to move downward, translate and then upward;

[0029] By moving downward, the mobile support plate can no longer be in contact with the top of the goaf. By moving horizontally, the positions of the mobile box and the mobile support plate can be moved. By moving upward again, the mobile support plate can be brought into contact with the top of the goaf again. Through the above operations, the mobile box and the mobile support plate can be adjusted separately when the base and the adjustment assembly are fixed, thereby realizing the adjustment of the support area and filling area of ​​the goaf. By setting the fixed support plate, the mobile support plate and the hydraulic support rod, the goaf can also be effectively supported during filling to avoid collapse of the goaf.

[0030] 2. The present invention realizes convenient transportation and efficient filling of the paste by connecting the conveying pipeline with the ground paste conveying pipeline. The design of the filling baffle effectively isolates the poured paste and the device, ensuring the smooth progress of the filling work. The application of the bellows enables the discharge pipe to freely extend and retract with the moving box when the auxiliary adjustment component drives the moving support component to move, ensuring the continuity and uniformity of the filling.

[0031] 3. The present invention sets up a lateral adjustment component. When in use, the hydraulic support rod can be extended outward by adjusting the lateral adjustment component to assist in supporting the side wall of the goaf, making the entire goaf more stable. At the same time, through the setting of the connecting component, when in use, when the two connecting rods move, the connecting plate drives the piston rod to slide through the connecting component at the same time, so that the pressure in the hydraulic tank changes, and the hydraulic support rod is adjusted with the movement of the connecting rod and the movable support plate, so that the movable support plate can move smoothly. When the movable support plate is fixed, the two hydraulic support rods extend outward again to support the side wall of the goaf again. The auxiliary support function of the hydraulic support rods on both sides further enhances the stability of the support structure, and effectively prevents the risk of collapse of the goaf.

[0032] 4. The present invention provides a folding assembly, and after completing the filling work, the device can fold the filling baffle to no longer be perpendicular to the moving box through the action of the second electric push rod and the connecting rod, and make the moving box bend, thereby greatly reducing the occupied area of ​​the device. This design not only facilitates the movement and transportation of the equipment, but also improves the reusability and economy of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] When the device is needed to be used, the base 1 is first connected to the coal mining machine so that the entire device can move synchronously with the movement of the coal mining machine. At the same time, before use, the filling baffle 34 can be folded and the mobile support component can be bent by the folding component 8 to reduce the overall area of ​​the device and facilitate entry into the goaf. After entering, the mobile support component and the filling baffle 34 are adjusted to the working state by adjusting the folding component 8;

[0046] By starting the hydraulic rod 11, the hydraulic rod 11 drives the vertical support adjustment assembly 2 and the mobile support assembly to move upward until the tops of the vertical support adjustment assembly 2 and the mobile support assembly are in contact with the top of the goaf. The top of the goaf is supported by the vertical support adjustment assembly 2 and the mobile support assembly to prevent the goaf from collapsing during filling. The auxiliary adjustment assembly provided on the vertical support adjustment assembly 2 can drive the mobile support assembly to move in the direction of the vertical support adjustment assembly 2 during use, thereby increasing the irrigation area of ​​the goaf and improving the filling efficiency.

[0047] The delivery pipeline 4 is connected to the ground paste delivery pipeline, so that the filling paste is delivered to the vertical limit groove 53 through the push plate 51 and the connecting rod 52 and poured through the vertical limit groove 53 to fill the goaf. The filling baffle 34 is set, and during the filling, the filling baffle 34 can isolate and block the poured paste from the device to facilitate the filling work. The connecting rod 52 is set between the push plate 51 and the vertical limit groove 53. When the auxiliary adjustment component drives the moving support component to move, the connecting rod 52 can facilitate the vertical limit groove 53 to extend and retract following the movement of the moving box 3.

[0048] For example 2, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 The vertical support adjustment assembly 2 includes a fixed box 21, and first pillars are installed on the four corners of the top of the fixed box 21.

[0049] During use, when the hydraulic rod 11 drives the vertical support adjustment assembly 2 to move upward, the fixed box 21 and the fixed support plate 22 move upward synchronously until the top of the fixed support plate 22 contacts the top of the goaf, and through the auxiliary adjustment assembly arranged in the fixed box 21, when the fixed box 21 moves upward, the movable box 3 and the movable support plate 31 are simultaneously driven to move upward, so that the top of the movable support plate 31 also contacts the top of the goaf, and the goaf is supported by the fixed support plate 22 and the movable support plate 31. At the same time, by arranging the conveying pipeline 4 below the fixed support plate 22 and the movable support plate 31, the conveying pipeline 4 can be protected by the fixed support plate 22 and the movable support plate 31 during use to prevent falling gravel from damaging the push plate 51 and the vertical limit groove 53.

[0050] For example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 The auxiliary adjustment component includes a first electric push rod 5, the output end of the first electric push rod 5 is fixedly connected to a push plate 51, and the two sides of the push plate 51 near the bottom are fixedly connected to sliders 54, and the two sliders 54 are respectively slidably connected to adjacent horizontal limit grooves 25. The side of the push plate 51 away from the first electric push rod 5 is slidably connected to two connecting rods 52, and the side of the push plate 51 away from the first electric push rod 5 is provided with two vertical limit grooves 53. The two connecting rods 52 are installed with limit rods at one end close to the push plate 51, and the two limit rods are slidably connected to the adjacent vertical limit grooves 53. Two first sliding blocks 55 are also respectively installed on the two connecting rods 52. A plurality of first sliding blocks 55 are slidably connected in adjacent notches respectively, one end of the two connecting rods 52 away from the first electric push rod 5 penetrates the fixed box 21 and extends to the outside of the fixed box 21, the extended ends of the two connecting rods 52 are rotatably connected to the adjacent first connecting blocks 32, and damping washers are arranged between the inner walls on both sides of the first connecting blocks 32 and the adjacent connecting rods 52, two limit rings 56 are also installed on the two connecting rods 52, and connecting holes 57 are also opened inside the two connecting rods 52, the ends of the two connecting holes 57 close to the hydraulic tank 6 are connected to the hydraulic tank 6, and the other ends of the two connecting holes 57 are connected to the hydraulic support rod 58;

[0051] When in use, the fixed box 21 can be connected to the movable box 3 through two connecting rods 52, so that the movable box 3 moves up and down synchronously with the fixed box 21;

[0052] When the movable box 3 needs to be adjusted separately, the first electric push rod 5 is started, so that the first electric push rod 5 pushes the push plate 51 to move, so that the sliders 54 on both sides of the push plate 51 slide along the transverse limit grooves 25 on the inner wall of the fixed box 21. When the push plate 51 slides, the two connecting rods 52 connected to the other side of the push plate 51 move with the push plate 51 at the same time. Since the connecting rod 52 is provided with a first sliding block 55, and the first sliding block 55 slides on the notch, when the push plate 51 pulls the connecting rod 52 to move, the first sliding block 55 will slide along the track of the notch.

[0053] In the initial position, the first sliding block 55 is located on the horizontal sliding groove 24. When the push plate 51 drives the connecting rod 52 to move, the first sliding block 55 slides from the horizontal sliding groove 24 to the arc-shaped sliding groove 23, and at the same time makes the connecting rod 52 slide downward along the vertical limiting groove 53. When sliding to the upward arc-shaped sliding groove 23, the connecting rod 52 slides upward along the vertical limiting groove 53, and the first sliding block 55 slides to the next horizontal sliding groove 24, closing the first electric push rod 5, fixing the push plate 51 and the connecting rod 52, and completing one adjustment work;

[0054] When the connecting rod 52 slides up and down under the action of the push plate 51, the movable box 3 connected to the connecting rod 52 moves at the same time as the connecting rod 52 moves. When the first sliding block 55 drives the connecting rod 52 to move to the descending arc-shaped sliding groove 23, the movable box 3 moves downward with the movable support plate 31 at the same time, so that the movable support plate 31 no longer contacts the top of the goaf. When the connecting rod 52 slides in the upward arc-shaped sliding groove 23, it pulls the movable box 3 at the same time to drive the movable support plate 31 to move in the direction of the fixed box 21 and then move upward. When the first sliding block 55 drives the connecting rod 52 to move to the next horizontal sliding groove 24, the top of the movable support plate 31 contacts the top of the goaf again. At this time, the position adjustment of the movable box 3 and the movable support plate 31 is completed;

[0055] The first electric push rod 5 is closed to fix the connecting rod 52 and the moving box 3, so that the moving support plate 31 continues to support the goaf.

Slide grooves 66 are provided on both sides of the U-shaped moving block 64. Second sliding blocks 67 are slidably connected in the two slide grooves 66. The ends of the two second sliding blocks 67 away from the U-shaped moving block 64 slide in the adjacent arc-shaped sliding grooves 23 respectively, and the two The second sliding blocks 67 are all located at the lowest point of the arc-shaped sliding groove 23. A connecting plate 68 is also provided above the U-shaped moving block 64. The two ends of the connecting plate 68 are respectively fixed to the two second sliding blocks 67.

The other ends of the two first connecting rods 75 are hinged with third connecting blocks 76, and the two third connecting blocks 76 are both installed on the connecting disk 63.

[0057] When the mobile support plate 31 is fixed to support the top of the goaf, the hydraulic support rods 58 on the two connecting rods 52 extend outward at the same time to provide auxiliary support for the side walls of the goaf. When the push plate 51 drives the two connecting rods 52 to move, the U-shaped moving block 64 is pulled to slide in the fixed box 21 through the limiting of the two limiting rings 56. When the U-shaped moving block 64 slides, the second sliding blocks 67 arranged on both sides of the U-shaped moving block 64 slide along the trajectory of the arc-shaped sliding groove 23, and move up and down under the limiting of the sliding groove 66. When the two second sliding blocks 67 slide downward, the moving rack 71 is driven to move downward through the connecting plate 68, so that the moving rack 71 drives the rotating gear 72 to rotate, and the two rotating disks 74 are driven to rotate at the same time through the synchronization rod 73.

[0058] When the two rotating disks 74 rotate, the first connecting rod 75 arranged thereon pulls the connecting disk 63 to move through the third connecting block 76, so that the connecting disk 63 drives the piston rod 62 to slide outward in the hydraulic tank 6, so that the pressure in the hydraulic tank 6 changes, so that the liquid in the communicating hole 57 flows back to the hydraulic tank 6 through the liquid outlet pipe 61, so that the two hydraulic support rods 58 no longer support the side wall of the goaf, so that the movable support plate 31 can move smoothly;

[0059] When the two first sliding blocks 55 move to the rising section of the arc-shaped sliding groove 23, the second sliding block 67 synchronously drives the connecting plate 68 and the moving rack 71 to move upward, thereby driving the rotating gear 72 and the two rotating disks 74 to rotate in the opposite direction, so that the two rotating disks 74 drive the first connecting rod 75 to push the connecting disk 63, and transport the liquid in the hydraulic tank 6 to the connecting hole 57 through the liquid outlet pipe 61, so that the two hydraulic support rods 58 extend outward to support the side wall of the goaf again.

[0061] When the device needs to be folded after use, the second electric push rod 82 is first started to make the output end of the second electric push rod 82 retract into the second electric push rod 82. At the same time, the filling baffle 34 is pulled along the second connecting block 33 under the action of the second connecting rod 83 and the fourth connecting block 84 to flip the filling baffle 34 to fold it until it is no longer perpendicular to the moving box 3. When the filling baffle 34 is folded, the second electric push rod 82 continues to retract, and the moving box 3 is bent under the action of the filling baffle 34 and the first connecting block 32, thereby reducing the occupied area of ​​the device and facilitating the removal of the device from the goaf.

[0062] When it is necessary to unfold the folded device, start the second electric push rod 82 again, so that the second electric push rod 82 drives the second connecting rod 83 and the fourth connecting block 84 to move outward, and pushes out the filling baffle 34. After being pushed out, the mobile box 3 is reset to a horizontal state with the auxiliary push of the filling baffle 34, so that the filling baffle 34 is perpendicular to the mobile box 3. When the filling baffle 34 is perpendicular to the mobile box 3, the second electric push rod 82 can no longer push the filling baffle 34 to move, and the second electric push rod 82 is closed. A triangular support is formed by the second electric push rod 82, the second connecting rod 83, the filling baffle 34 and the mobile box 3 to ensure the stability of the mobile box 3 and the filling baffle 34, while improving the stability of the mobile support plate 31 supporting the goaf.

[0063] The working principle of the present invention is as follows: when the device is needed, the base 1 is first connected to the coal mining machine so that the entire device can move synchronously with the movement of the coal mining machine, and the hydraulic rod 11 is started to drive the vertical support adjustment assembly 2 and the movable support assembly to move upward until the top of the fixed support plate 22 and the movable support plate 31 are in contact with the top of the goaf, and the top of the goaf is supported by the fixed support plate 22 and the movable support plate 31. At the same time, the hydraulic support rods 58 on the two connecting rods 52 are simultaneously extended outward to support the side wall of the goaf. Auxiliary support connects the delivery pipe 4 with the ground paste delivery pipe, so that the filling paste is delivered to the vertical limit groove 53 through the push plate 51 and the connecting rod 52 and poured through the vertical limit groove 53 to fill the goaf. During the filling, the filling baffle 34 can isolate and block the poured paste from the device to facilitate the filling work. By setting the connecting rod 52 between the push plate 51 and the vertical limit groove 53, when the auxiliary adjustment component drives the mobile support component to move, the connecting rod 52 can facilitate the vertical limit groove 53 to follow the movement of the mobile box 3 and extend and retract;

[0064] When the movable box 3 needs to be adjusted separately, the first electric push rod 5 is started, so that the first electric push rod 5 pushes the push plate 51 to move, so that the sliders 54 on both sides of the push plate 51 slide along the transverse limit grooves 25 on the inner wall of the fixed box 21. When the push plate 51 slides, the two connecting rods 52 connected to the other side of the push plate 51 move with the push plate 51 at the same time. Since the connecting rod 52 is provided with a first sliding block 55, and the first sliding block 55 slides on the notch, when the push plate 51 pulls the connecting rod 52 to move, the first sliding block 55 will slide along the track of the notch.

[0065] In the initial position, the first sliding block 55 is located on the horizontal sliding groove 24. When the push plate 51 drives the connecting rod 52 to move, the first sliding block 55 slides from the horizontal sliding groove 24 to the arc-shaped sliding groove 23, and at the same time makes the connecting rod 52 slide downward along the vertical limiting groove 53. When sliding to the upward arc-shaped sliding groove 23, the connecting rod 52 slides upward along the vertical limiting groove 53, and the first sliding block 55 slides to the next horizontal sliding groove 24, closing the first electric push rod 5, fixing the push plate 51 and the connecting rod 52, and completing one adjustment work;

[0066] When the connecting rod 52 slides up and down under the action of the push plate 51, the movable box 3 connected to the connecting rod 52 moves at the same time as the connecting rod 52 moves. When the first sliding block 55 drives the connecting rod 52 to move to the descending arc-shaped sliding groove 23, the movable box 3 moves downward with the movable support plate 31 at the same time, so that the movable support plate 31 no longer contacts the top of the goaf. When the connecting rod 52 slides in the upward arc-shaped sliding groove 23, it pulls the movable box 3 at the same time to drive the movable support plate 31 to move in the direction of the fixed box 21 and then move upward. When the first sliding block 55 drives the connecting rod 52 to move to the next horizontal sliding groove 24, the top of the movable support plate 31 contacts the top of the goaf again. At this time, the position adjustment of the movable box 3 and the movable support plate 31 is completed;

[0067] When the push plate 51 drives the two connecting rods 52 to move, the U-shaped moving block 64 is pulled to slide in the fixed box 21 through the limit of the two limit rings 56. When the U-shaped moving block 64 slides, the second sliding blocks 67 arranged on both sides of the U-shaped moving block 64 slide along the track of the arc-shaped sliding groove 23, and move up and down under the limit of the sliding groove 66. When the two second sliding blocks 67 slide downward, the moving rack 71 is driven to move downward through the connecting plate 68, so that the moving rack 71 drives the rotating gear 72 to rotate, and the two rotating disks 74 are driven to rotate at the same time through the synchronization rod 73.

[0068] When the two rotating disks 74 rotate, the first connecting rod 75 arranged thereon pulls the connecting disk 63 to move through the third connecting block 76, so that the connecting disk 63 drives the piston rod 62 to slide outward in the hydraulic tank 6, so that the pressure in the hydraulic tank 6 changes, so that the liquid in the communicating hole 57 flows back to the hydraulic tank 6 through the liquid outlet pipe 61, so that the two hydraulic support rods 58 no longer support the side wall of the goaf, so that the movable support plate 31 can move smoothly;

[0069] When the two first sliding blocks 55 move to the rising section of the arc-shaped sliding groove 23, the second sliding block 67 synchronously drives the connecting plate 68 and the moving rack 71 to move upward, thereby driving the rotating gear 72 and the two rotating disks 74 to rotate in the opposite direction, so that the two rotating disks 74 drive the first connecting rod 75 to push the connecting disk 63, and the liquid in the hydraulic tank 6 is transported to the connecting hole 57 through the liquid outlet pipe 61, so that the two hydraulic support rods 58 extend outward to support the side wall of the goaf again;

[0070] When the device needs to be folded after use, the second electric push rod 82 is first started to make the output end of the second electric push rod 82 retract into the second electric push rod 82, and the filling baffle 34 is pulled along the second connecting block 33 under the action of the second connecting rod 83 and the fourth connecting block 84 to flip the filling baffle 34 along the second connecting block 33, so that the filling baffle 34 is folded until it is no longer perpendicular to the moving box 3. When the filling baffle 34 is folded, the second electric push rod 82 continues to retract, and the moving box 3 is bent under the action of the filling baffle 34 and the first connecting block 32, thereby reducing the occupied area of ​​the device and facilitating the device to be moved out of the goaf.

[0071] When it is necessary to unfold the folded device, start the second electric push rod 82 again, so that the second electric push rod 82 drives the second connecting rod 83 and the fourth connecting block 84 to move outward, and pushes out the filling baffle 34. After being pushed out, the mobile box 3 is reset to a horizontal state with the auxiliary push of the filling baffle 34, so that the filling baffle 34 is perpendicular to the mobile box 3. When the filling baffle 34 is perpendicular to the mobile box 3, the second electric push rod 82 can no longer push the filling baffle 34 to move, and the second electric push rod 82 is closed. A triangular support is formed by the second electric push rod 82, the second connecting rod 83, the filling baffle 34 and the mobile box 3 to ensure the stability of the mobile box 3 and the filling baffle 34, while improving the stability of the mobile support plate 31 supporting the goaf.
