Description

Technical Field

[0001] The present invention relates to the technical field of coal mine filling, and particularly to an automatic filling device for a coal mine gob area. Background Art

[0002] Backfilling of a coal mine gob area can effectively support the roof of the gob area, reduce the scope and degree of roof collapse, thereby significantly reducing the surface subsidence amount, protecting surface buildings, farmland, etc. from damage, and creating conditions for subsequent operations by forming a new working face, shortening the mining and filling cycle, improving the comprehensive production capacity of mining.

Detailed Embodiments

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0050] Before further describing the embodiments of the present invention in detail, the directional terms involved in the embodiments of the present invention, such as "upper part", "lower part", "side part", are based on Figure 1 the directions shown in [the figure], and do not have the meaning of limiting the protection scope of the present invention.

[0051] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the drawings.

[0052] As described above, because the roadway conditions in the goaf are complex and highly irregular, the existing devices cannot effectively ensure the filling density and the roof - contacting rate. Therefore, this application provides an automatic filling device for coal mine goafs.

[0053] AsFigures 1 to 7 As shown in the figure, an automatic filling device for a goaf in a coal mine includes a traveling mechanism and an isolation mechanism 4. The isolation mechanism 4 is arranged on the traveling mechanism, and the isolation mechanism 4 abuts against the filler and the peripheral wall of the goaf. The isolation mechanism 4 includes an extended isolation component, a first driving component, and an isolation cover 410. The extended isolation component is connected to the traveling mechanism, the first driving component is arranged on the extended isolation component, and the isolation cover 410 covers the first driving component. The first driving component is used to drive the isolation cover 410 to deform so that the isolation cover 410 abuts against the filler and the peripheral wall of the goaf, and the extended isolation component is used to drive the first driving component to move in a direction away from or close to the peripheral wall of the goaf. In this application, the isolation cover 410 in the isolation mechanism 4 can deform under the drive of the first driving component. The deformed isolation cover 410 abutting against the filler can improve the density of the filler, and the deformed isolation cover 410 abutting against the peripheral wall of the goaf can improve the roof contact rate. The setting of the extended isolation component further enhances the deformation amount of the isolation cover 410, and further improves the filler density and the roof contact rate.

[0054] Exemplarily, such as Figure 1 and Figure 3 As shown in the figure, the isolation cover 410 includes a first plate perpendicular to the axis of the isolation cover 410, a second plate, a third plate, a fourth plate, a fifth plate, a sixth plate, a seventh plate, an eighth plate, and a ninth plate parallel to the axis of the isolation cover 410. The second plate, the third plate, the fourth plate, the fifth plate, the sixth plate, the seventh plate, the eighth plate, and the ninth plate are all connected to the first plate. The second plate and the sixth plate are arranged parallel and opposite to each other, the third plate and the seventh plate are arranged parallel and opposite to each other, the fourth plate and the eighth plate are arranged parallel and opposite to each other, and the fifth plate and the ninth plate are arranged parallel and opposite to each other. The isolation cover 410 may further include a tenth plate arranged parallel and opposite to the first plate.

[0055] Exemplarily, the first driving component includes a first driving structure and a second driving structure. The first driving structure is arranged on the circumferential side parallel to the axis of the extended isolation component. The first driving structure is used to drive the isolation cover 410 to deform so that the isolation cover 410 abuts against the peripheral wall of the goaf. That is, the first driving structure is connected to the second plate to the ninth plate. The first driving structure includes a first driving member 45, a second driving member 47, and a third driving member 46. The outer contour of the extended isolation component is rectangular. The first driving member 45 is arranged on the first side and the second side of the extended isolation component arranged parallel and opposite to each other. The second driving member 47 is arranged on the third side and the fourth side of the extended isolation component arranged parallel and opposite to each other. The third driving member 46 is arranged at the four included angles of the outer contour of the extended isolation component. Taking Figure 4 the shown orientation as an example, the first side of the extended isolation component is the left side of the extended isolation component, the second side of the extended isolation component is the right side of the extended isolation component, the third side of the extended isolation component is the upper side of the extended isolation component, and the fourth side of the extended isolation component is the lower side of the extended isolation component. Taking Figure 3 andFigure 4 As shown, the first driving member 45, the second driving member 47, and the third driving member 46 are all hydraulic cylinders, and multiple of each are provided. Multiple first driving members 45 are arranged along the first side of the extended isolation assembly, multiple first driving members 45 are arranged along the second side of the extended isolation assembly, multiple second driving members 47 are arranged along the third side of the extended isolation assembly, multiple second driving members 47 are arranged along the fourth side of the extended isolation assembly, and one third driving member 46 is provided at each of the four corners of the outer contour of the extended isolation assembly. The fixed ends of the first driving member 45, the second driving member 47, and the third driving member 46 are connected to the extended isolation assembly, and the telescopic end of the first driving member 45 is connected to the isolation cover 410. The first driving member 45 arranged along the first side of the extended isolation assembly is connected to the fourth plate, the first driving member 45 arranged along the second side of the extended isolation assembly is connected to the eighth plate, the second driving member 47 arranged along the third side of the extended isolation assembly is connected to the second plate, the second driving member 47 arranged along the fourth side of the extended isolation assembly is connected to the sixth plate, and the four third driving members 46 provided at the four corners are respectively connected to the third plate, the fifth plate, the seventh plate, and the ninth plate.

[0056] Exemplarily, the second driving structure is arranged on a side perpendicular to the axis of the extended isolation assembly, and the second driving structure is used to drive the isolation cover 410 to deform so that the isolation cover 410 abuts against the packing. That is, the second driving structure is in contact with the first plate. The second driving structure includes a fourth driving member 48, and the fourth driving member 48 is a hydraulic cylinder. Multiple fourth driving members 48 are provided, the fixed ends of the multiple fourth driving members 48 are connected to the extended isolation assembly, and the telescopic ends of the multiple fourth driving members 48 are connected to the first plate.

[0057] Exemplarily, the deformation directions of the isolation cover 410 driven by the first driving member 45, the second driving member 47, and the third driving member 46 are all perpendicular to the axis of the extended isolation assembly, so that the isolation cover 410 fits better with the peripheral wall of the gob roadway and has stronger adaptability to the irregular wall surface of the gob. The deformation direction of the isolation cover 410 driven by the fourth driving member 48 is parallel to the axis of the extended isolation assembly, so that the isolation cover 410 abuts against the packing, further compressing the packing and improving the compaction degree of the packing. The isolation cover 410 is made of a material with certain elasticity.

[0058] The settings of the first driving member 45, the second driving member 47, and the third driving member 46 can minimize the gap between the isolation mechanism 4 and the peripheral wall of the gob, thus effectively preventing the leakage of the filling material and further improving the filling quality and filling efficiency. The setting of the fourth driving member 48 can further compress the filling solvent in the closed space, thereby improving the compaction degree and roof contact rate of the filling.

[0059] Exemplarily, the isolation mechanism 4 further includes anti-damage blocks 49. A plurality of anti-damage blocks 49 are provided, and an anti-damage block 49 is provided at the junction of each of the first driving member 45, the second driving member 47, the third driving member 46, the fourth driving member 48 and the isolation cover 410. The anti-damage block 49 has a certain elasticity and has a buffering effect, effectively reducing the damage suffered by the first driving member 45, the second driving member 47, the third driving member 46, the fourth driving member 48 and the isolation cover 410. At the same time, it can also cause the hydraulic controller 5 controlling the first driving member 45, the second driving member 47, the third driving member 46 and the fourth driving member 48 to appropriately increase the pressure, thereby improving the compaction degree and roof contact rate of the filling.

[0060] Exemplarily, such as Figure 3 , Figure 4 , Figure 5 shown, the stretching isolation assembly includes a stretching assembly 43 and a second driving assembly. The second driving assembly is connected to the traveling mechanism. Two stretching assemblies 43 are provided. The two stretching assemblies 43 are connected to the second driving assembly. The two stretching assemblies 43 are hinged. The second driving assembly is used to drive an included angle to be formed between the two stretching assemblies 43. The second driving assembly is further used to drive the two stretching assemblies 43 to rotate circumferentially around the axis of the stretching isolation assembly. The second driving assembly can cause an included angle to be formed between the two stretching assemblies 43, so that the first plate undergoes a micro-deformation and bending, and the filler filled in the stretching isolation assembly forms a filling shape with an inclined surface, while ensuring the roof contact rate of the filling, reducing the subsequent filling difficulty. At the same time, the second driving assembly can drive the two stretching assemblies 43 to rotate circumferentially around the axis of the stretching isolation assembly, so as to adjust the direction of the included angle formed by the two stretching assemblies 43, so as to cope with the complex goaf environment, further improving the practicability of the automatic filling device for coal mine goafs and ensuring the filling efficiency.

[0061] Exemplarily, such as Figure 3 and Figure 4As shown in the figure, the second driving assembly includes a fifth driving member 41, a sixth driving member 44 and a rotating disk 42; the fifth driving member 41 is arranged on the traveling mechanism, the rotating disk 42 is arranged on the fifth driving member 41, the sixth driving member 44 is arranged on the rotating disk 42, an extension assembly 43 is arranged on the rotating disk 42, and the other extension assembly 43 is connected to the sixth driving member 44; the fifth driving member 41 is used to drive the rotating disk 42 to drive the two extension assemblies 43 to rotate circumferentially around the axis of the extension isolation assembly, and the sixth driving member 44 is used to drive one extension assembly 43 to rotate relative to the other extension assembly 43 so as to form an included angle between the two extension assemblies 43. Specifically, both the fifth driving member 41 and the sixth driving member 44 are driving motors, and the driving shaft of the fifth driving member 41 is connected to the center of the rotating disk 42. The rotating disk 42 can be circular, square or other shapes, and no specific limitation is made here. A rotating shaft connected to the sixth driving member 44 is provided on the extension assembly 43 not fixed on the rotating disk 42, and the extending direction of the axis of the rotating shaft is perpendicular to the extending direction of the axis of the driving shaft of the fifth driving member 41. The sixth driving member 44 drives the extension assembly 43 not fixed on the rotating disk 42 to rotate relative to the extension assembly 43 fixed on the rotating disk 42 through the rotating shaft, so as to form an included angle between the two extension assemblies 43. The axis of the extension isolation assembly is coaxially arranged with the axis of the rotating disk 42.

[0062] Exemplarily, as Figure 5 shown, the extension assembly 43 includes a telescopic link structure 435, a fixing frame, an adjusting column 433, a seventh driving member 438, and a threaded rod 437. The fixing frame includes a fixing column 431 and a slide rail 432. A slide rail 432 is arranged at each end of the fixing column 431, and the length direction of the slide rail 432 is parallel to the telescopic direction of the telescopic link structure 435. The adjusting column 433 is arranged parallel to the fixing column 431. A plurality of adjusting columns 433 are provided, and the plurality of adjusting columns 433 are connected to the fixing column 431 through the telescopic link structure 435. The two ends of the adjusting column 433 are slidably connected to the slide rail 432. The seventh driving member 438, the threaded rod 437 and the fixing column 431 are connected, and the threaded rod 437 is threadedly connected to the plurality of adjusting columns 433. The seventh driving member 438 is used to drive the adjusting column 433 to move along the telescopic direction of the telescopic link structure 435.

[0063] Exemplarily, in combination with Figure 4 and Figure 5 shown, the fixing column 431 is arranged on the side of the extension assembly 43 close to the center of the rotating disk 42. The fixing columns 431 of the two extension assemblies 43 are hinged. The fixing column 431 of the extension assembly 43 not fixed on the rotating disk 42 is connected to the sixth driving member 44, and the fixing column 431 of the extension assembly 43 fixed on the rotating disk 42 is connected to the rotating disk 42.

[0064] Exemplarily, in combination with Figure 4 andFigure 5 As shown, in each stretching component 43 of the present application, multiple sets of telescopic link structures 435 are provided to ensure the connection stability between the adjusting column 433 and the fixed column 431. It can be understood that, in one embodiment, the adjusting columns 433 are arranged in pairs, and a pair of adjusting columns 433 are arranged at the same connection joint of the telescopic link structure 435, including a front row adjusting column 433 and a rear row adjusting column 433 corresponding to the front row adjusting column 433. In another embodiment, joint holes are provided on the adjusting column 433, and the telescopic link structure 435 is connected to the joint holes on the adjusting column 433.

[0065] Exemplarily, as Figure 4 and Figure 5 shown, slide rails 432 are respectively provided at the upper end and the lower end of the fixed column 431, and the slide rails 432 are arranged between two rows of adjusting columns 433. Preferably, the stretching component 43 further includes pulleys 434, the pulleys 434 are arranged at the ends of the adjusting columns 433, and the pulleys 434 are slidably connected to the slide rails 432 to prevent the adjusting columns 433 from disengaging from the slide rails 432 when stretching or contracting.

[0066] Exemplarily, as Figure 4 and Figure 5 shown, the first driving member 45 is connected to the outermost adjusting column 433, the second adjusting member is connected to the slide rail 432, and the third driving member 46 is connected to one end of the slide rail 432. The adjusting column 433 can be driven by the seventh driving member 438 to move along the telescopic direction of the telescopic link structure 435, and further drive the first driving member 45 to drive the isolation cover 410 to further deform, so as to better adhere to the wall surface of the irregular gob area.

[0067] Exemplarily, as Figure 4 and Figure 5 shown, the seventh driving member 438 is a driving motor, and the driving motors on the two telescopic components are located on both sides of the center of the rotating disk 42 to avoid interference between the two seventh driving members 438. As Figure 5 shown, when the seventh driving member 438 is started, the fixed column 431 remains stationary, and a threaded transmission occurs between the adjusting column 433 and the threaded rod 437. According to the rotation direction of the driving shaft of the seventh driving member 438, the adjusting column 433 moves in a direction close to or away from the fixed column 431. The setting of the threaded rod 437 can provide stretching power for the stretching component 43 under the drive of the seventh driving member 438, thereby increasing the isolation range of the isolation mechanism 4 and further improving the filling efficiency.

[0068] Exemplarily, as Figure 4 and Figure 5As shown, the stretching component 43 further includes a sliding rod 436. The sliding rod 436 is connected to the fixed column 431. The length direction of the sliding rod 436 is parallel to the telescopic direction of the telescopic link structure 435. The sliding rod 436 is slidably connected to a plurality of adjusting columns 433 to prevent the adjusting columns 433 from detaching from the slide rail 432 when they stretch or contract. The setting of the sliding rod 436 can also keep the adjusting columns 433 that have detached from the slide rail 432 moving in the horizontal direction, avoiding complete detachment and damage of the adjusting columns 433.

[0069] Exemplarily, as Figure 1 As shown, the automatic filling device for coal mine goafs further includes a hydraulic controller 5. The hydraulic controller 5 is arranged above the support plate. The hydraulic controller 5 is connected to the hydraulic cylinder to control the start of the hydraulic cylinder. Specifically, the hydraulic controller 5 includes a hydraulic oil tank 51, an oil pump 52, a first pressure booster 53, and a pressure controller 54. The hydraulic oil tank 51 is fixedly assembled on the upper surface of the bearing plate 1. The oil pump 52 is fixedly arranged on the upper surface of the hydraulic oil tank 51. The oil pump 52 is connected to the first pressure booster 53. The first pressure booster 53 is connected to the pressure controller 54. The pressure controller 54 is provided with four output ports, all of which are connected to the isolation mechanism 4. Specifically, the four output ports of the pressure controller 54 are respectively connected to a plurality of first driving members 45, a plurality of second driving members 47, a plurality of third driving members 46, and a plurality of fourth driving members 48 to control the telescopic amounts of the plurality of first driving members 45, the plurality of second driving members 47, the plurality of third driving members 46, and the plurality of fourth driving members 48. Specifically, the sequential driving of the plurality of first driving members 45, the plurality of second driving members 47, the plurality of third driving members 46, and the plurality of fourth driving members 48 by the pressure controller 54 means that, first, the telescopic amounts of the plurality of first driving members 45 are controlled so that the fourth plate and the eighth plate of the isolation sleeve are in contact with the two side walls of the roadway; second, the telescopic amounts of the plurality of second driving members 47 are controlled so that the second plate and the sixth plate of the isolation sleeve are in contact with the roof and the ground of the roadway; third, the telescopic amounts of the plurality of third driving members 46 are controlled so that the third plate, the fifth plate, the seventh plate, and the ninth plate of the isolation sleeve are in contact with the peripheral wall of the roadway; and fourth, the plurality of fourth driving members 48 are controlled to be in contact with the filling material.

[0070] The setting of the hydraulic controller 5 can make the edge of the isolation mechanism 4 fit tightly with the peripheral wall of the goaf roadway, prevent the filling material from leaking, and at the same time, the hydraulic controller 5 can apply a uniform pressure to the edge of the isolation mechanism 4, thereby avoiding damage to the automatic filling device for coal mine goafs caused by excessive pressure at a certain place.

[0071] Exemplarily, as Figure 1 and Figure 2As shown in the figure, the automatic filling device for the goaf of a coal mine further includes an adjustment mechanism 3. The adjustment mechanism 3 includes a first adjustment component and a second adjustment component. The first adjustment component is connected to the traveling mechanism, the second adjustment component is arranged on the first adjustment component, and the isolation mechanism is arranged on the second adjustment component. The first adjustment component is used to adjust the angle between the axis of the extended isolation component and the cross-section of the goaf, and the second adjustment component is used to adjust the height between the isolation mechanism and the ground of the goaf.

[0072] Exemplarily, as Figure 2 shown, the angle between the axis of the extended isolation component and the cross-section of the goaf always takes a value less than or equal to 90°. In the original position, the angle between the axis of the extended isolation component and the cross-section of the goaf is 90°. As Figure 1 shown, after adjustment, the angle between the axis of the extended isolation component and the cross-section of the goaf is less than 90°. For example, the first adjustment component can control the pitching motion of the axis of the extended isolation component relative to the ground of the goaf, and the first adjustment component can also control the left-right swing of the axis of the extended isolation component relative to the side wall of the goaf.

[0073] Exemplarily, as Figure 1 and Figure 2 shown, the first adjustment component includes a fixed plate 31, a fixed block 33, a connecting rod 32, an eighth driving member 34, and a ninth driving member 35. The second adjustment component includes a sliding track 36 and a sliding block 37. The fixed plate 31 is connected to the traveling mechanism. The first end of the connecting rod 32 is connected to the fixed plate 31, and the second end of the connecting rod 32 is rotatably connected to the fixed block 33 through a first rotating shaft. The first end of the eighth driving member 34 is connected to the first end of the connecting rod 32, and the second end of the eighth driving member 34 is rotatably connected to the fixed block 33 through a second rotating shaft. The first end of the ninth driving member 35 is connected to the fixed plate 31, and the second end of the ninth driving member 35 is connected to the side wall of the connecting rod 32. The sliding track 36 is slidably connected to the fixed block 33, and the sliding block 37 is slidably connected to the sliding track 36. The setting of the first adjustment component increases the adjustment range of the angle between the adjustment isolation mechanism 4 and the cross-section of the goaf. The second adjustment component changes the relative height between the traveling mechanism and the isolation mechanism 4.

[0074] Exemplarily, as Figure 1As shown in the figure, the traveling mechanism includes a carrier plate 1 and traveling wheels 2. The traveling wheels 2 are arranged below the carrier plate 1. Driving the traveling wheels 2 can drive the carrier plate 1 to move. The fixing plate 31 is connected to the end of the carrier plate 1. The eighth driving member 34 and the ninth driving member 35 are hydraulic cylinders. The first end of the eighth driving member 34 is the fixed end of the hydraulic cylinder, the second end of the eighth driving member 34 is the telescopic end of the hydraulic cylinder, the first end of the ninth driving member 35 is the fixed end of the hydraulic cylinder, and the second end of the ninth driving member 35 is the telescopic end of the hydraulic cylinder. The eighth driving member 34 drives the axis of the extension isolation assembly to perform a pitching motion relative to the ground of the goaf, and the ninth driving member 35 drives the axis of the extension isolation assembly to swing left and right relative to the side wall of the goaf. The number of connecting rods 32 provided can be adjusted according to requirements.

[0075] Six traveling wheels 2 are provided, which have a shock-absorbing function. The arrangement of the traveling wheels 2 can ensure the stability of the operation of the automatic goaf filling device in coal mines, reduce the damage suffered by each mechanism, and at the same time can also cope with a relatively complex goaf environment.

[0076] Exemplarily, as Figure 1 shown, the length direction of the fixing plate 31 is parallel to the width direction of the carrier plate 1. As Figure 2 shown, the length direction of the fixing block 33, the length direction of the sliding track 36 are perpendicular to the length direction of the fixing plate 31. The sliding track 36 slides along the length direction of the fixing block 33, and the sliding block 37 slides along the length direction of the sliding track 36.

[0077] The adjustment mechanism 3 can adjust the placement position and placement angle of the isolation mechanism 4 in real time according to the actual situation, so as to ensure the filling effect and filling quality.

[0078] Exemplarily, as Figure 1 and Figure 7 shown, the automatic goaf filling device in coal mines further includes a filling production mechanism 6. The filling production mechanism 6 is arranged on the traveling mechanism. The filling production mechanism 6 and the isolation mechanism 4 are connected through a filling pipe 67. The filling production mechanism 6 includes a classifier 62, a stirrer 64, and a cementitious material tank 65. The classifier 62 is provided with a filler inlet 63 and a filler outlet. Multiple filler outlets are provided, and the filler outlets and the stirrer 64 are arranged in one-to-one correspondence. The stirrer 64 is connected to the filler outlet. The cementitious material tank 65 is connected to multiple stirrers 64, and the stirrer 64 and the isolation mechanism 4 are connected through a filling pipe 67.

[0079] Exemplarily, the filling production mechanism 6 further includes a support frame 61 which is fixed on the bearing plate 1. The support frame 61 is divided into upper and lower layers. The classifier 62 is fixed on the upper layer, and the agitator 64 and the cementitious material tank 65 are arranged on the lower layer and connected to the bearing plate 1. The filling production mechanism 6 further includes a second pressurizer 66 which is arranged between the agitator 64 and the filling pipe 67. During operation, the filler enters the classifier 62 through the filler inlet 63 and is crushed and classified by the classifier 62. The fillers of different particle size grades enter the corresponding agitators 64 through the corresponding filler outlets. The cementitious material in the cementitious material tank 65 is controlled to enter the corresponding agitator 64 according to the incorporation rate of the cementitious material required in different agitators 64. The filler and the cementitious material are stirred in the agitator 64 to obtain the filling material. The filling material is filled into the space between the isolation mechanism 4 and the roadway under the pressure of the second pressurizer 66 through the filling pipe 67 to complete the filling, thereby effectively supporting the roof of the goaf and reducing the scope and degree of roof collapse.

[0080] Exemplarily, two groups of filling production mechanisms 6 are arranged in this application. Six filling pipes 67 are connected by a bundle pipe, and the output ends of the filling pipes 67 are arranged on the isolation mechanism 4.

[0081] Exemplarily, as Figure 8 shown, after the goaf to be filled is divided according to the particle size of the waste minerals and the incorporation rate of the cementitious material, it can be divided into at most six levels, namely A, B, C, D, E, and F. According to the actual situation, the complex goaf environment is processed separately. On the premise of ensuring the density and roof contact rate, block treatment is carried out. The isolation mechanism 4 can block the goaf into blocks. Through the first driving component, the isolation mechanism 4 forms a closed space with the goaf wall of the block. After injecting the filling material into the closed space, the filling material in the closed space can also be compressed preferentially through the first driving component, the second driving component, and the adjusting mechanism 3 (for example, driving one extension component 43 to rotate relative to another extension component 43 to form an angle between the two extension components 43 to ensure the smooth injection of the subsequent filling material), so as to ensure the roof contact rate and density of the closed space. It is filled layer by layer from bottom to top until the filling of the top is completed. During the filling process, the filling material in the agitator 64 of the corresponding particle size grade is controlled to be filled according to the particle size requirements of the level. During the filling process, the isolation mechanism 4 blocks the filling material to prevent it from scattering until the filling requirements of this position are completed.
