Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gangue blocking, in particular to a gob-side entry retaining gangue blocking device. BACKGROUND

[0002] Gob-side entry retaining is to maintain the original mining roadway along the edge of the goaf after the coal mining face is mined. In order to recover the protective coal pillars left in the traditional mining method, certain technical means are used to re-support the crossheading of the previous section for use by the next section. This method of retaining the roadway is to retain the original crossheading along the edge of the goaf, which is called gob-side entry retaining. Gob-side entry retaining can maximize resource recovery and avoid coal loss.

[0003] When gob-side entry retaining technology is used, the roof is prone to fall off in a large area in the goaf after the coal mining face is mined, causing the gangue to easily slide into the roadway under the action of gravity. Therefore, it is necessary to block the gangue to avoid the gangue from sliding into the roadway. However, the existing gangue blocking device lacks a corresponding buffer structure, and the gangue directly falls on the gangue blocking net, which has a great impact on the gangue blocking net, easily causing damage to the gangue blocking net. Moreover, the damaged gangue blocking net cannot block the gangue from sliding, affecting the use effect and service life of the gangue blocking net. In addition, the inclination angle of the gangue blocking net cannot be adjusted, which cannot adapt to different use environments.

[0004] In view of the above problems, some solutions are also given in the prior art. For example, the Chinese utility model patent with publication number CN221799839U discloses a gob-side entry retaining gangue blocking device. The device is connected with the auxiliary gangue blocking plate through the hinged connection of the arc-shaped gangue blocking plate, cooperates with the arc-shaped structure of the arc-shaped gangue blocking plate, and combines the elastic action of the buffer spring, effectively buffers the falling gangue, and makes the gangue slowly slide down, solving the problem that the prior art lacks a corresponding buffer structure, the gangue directly falls on the gangue blocking net, which has a great impact on the gangue blocking net, and easily causes damage to the gangue blocking net. The mutual cooperation of the arc-shaped gangue blocking plate and the auxiliary gangue blocking plate achieves the purpose of double protection. Even if the arc-shaped gangue blocking plate is damaged, the auxiliary gangue blocking plate still has the function of blocking the gangue from sliding, improving the protection effect of the device. Although the prior art can improve the protection effect to a certain extent, when in use, gangue or coal blocks cannot be avoided from falling between the arc-shaped gangue blocking plate and the auxiliary gangue blocking plate, which affects the normal deformation of the buffer spring driven by the arc-shaped gangue blocking plate, thereby affecting the buffering effect of the falling gangue and the protection effect to a certain extent.

[0041] When gangue falls on the second gangue blocking plate 503, the second gangue blocking plate 503 will extrude the buffer spring 502 under the impact force of the gangue, at this time, the gangue can be buffered under the action of the second gangue blocking plate 503 and the buffer spring 502, avoiding the gangue falling on the gangue blocking net and causing a large impact force on the gangue blocking net, so that the gangue blocking net is easily damaged, affecting the protection effect, and at the same time, the metal air bag 501 is arranged to isolate the buffer spring 502 from the gangue, thereby avoiding the gangue being stuck on the buffer spring 502, affecting the service life of the buffer spring 502, and affecting the normal buffering of the buffer spring 502 to the gangue falling on the second gangue blocking plate 503, thereby improving the protection effect.

[0042] When the gangue slides off the second gangue blocking plate 503, the buffer spring 502 is stretched and drives the metal air bag 501 and the second gangue blocking plate 503 to reset, and in the process of resetting the metal air bag 501, air is sucked from the outside through the air inlet valve 605, and then in the process of compressing the metal air bag 501, the air in the metal air bag 501 flows to the water tank 601 through the exhaust valve 606 and the first air pipe 607, and in the process of air extraction and exhaust of the metal air bag 501, the impact of the gangue falling can be consumed, further improving the protection effect.

[0043] In the process of gangue falling, dust is easily raised, and then the dust diffuses everywhere, affecting the health of workers, and small particle gangue leaks, and then after the airflow flows to the water tank 601, the pressure in the water tank 601 increases, and then under the action of the pressure, the water flow in the water tank 601 flows to the water cavity 602 through the drain valve 604 and the through hole assembly 9, and sprays to the outside through the spray head 603 on the water cavity 602, thereby the dust can be sprayed and dust-settling treatment is performed on the dust, further improving the protection effect.

[0044] As shown in Figure 1 , Figure 6 , Figure 8 , the adjusting assembly 7 comprises a frame body 701 fixedly installed on the bottom wall of the top plate 3, a linkage plate 702 fixedly connected with the first gangue blocking plate 4 is rotatably installed on the frame body 701, a sliding slot is formed in the vertical plate 2, a sliding block 703 is slidably installed in the sliding slot, a connecting rod 704 is rotatably installed on the sliding block 703, a connecting plate 705 is rotatably installed on one end of the connecting rod 704 away from the sliding block 703, and a linkage rod 706 fixedly connected with the first gangue blocking plate 4 is fixedly installed on the connecting plate 705.

[0045] The vertical plate 2 is vertically rotatably provided with a threaded rod 707 threadedly matched with the sliding block 703, the top end of the threaded rod 707 is fixedly provided with a first bevel gear 708, the vertical plate 2 is horizontally rotatably provided with a rocker 709, the rocker 709 is fixedly provided with a second bevel gear 710 engaged with the first bevel gear 708, and the vertical plate 2 is provided with a locking assembly 8 for fixing the rocker 709.

[0046] By adopting the above technical scheme, when the angle of the second gangue blocking plate 503 needs to be adjusted, the user can drive the second bevel gear 710 to rotate through the rocker 709, drive the threaded rod 707 to rotate through the second bevel gear 710 and the first bevel gear 708, then drive the sliding block 703 to slide along the sliding groove in the process of rotation of the threaded rod 707, and drive the connecting plate 705 to move through the connecting rod 704 in the process of sliding of the sliding groove, drive the connecting plate 702 to rotate around the frame body 701 through the first gangue blocking plate 4 in the process of movement of the connecting plate 705, then drive the second gangue blocking plate 503 to rotate in the process of rotation of the first gangue blocking plate 4, and adjust the angle of the second gangue blocking plate 503, thereby facilitating the adjustment of the angle of the second gangue blocking plate 503.

[0047] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 The locking assembly 8 comprises a mounting plate 801 slidably mounted on the vertical plate 2, a side wall of the mounting plate 801 is provided with a linkage groove, a push rod 802 is slidably mounted in the linkage groove, a first spring 803 is jointly mounted between the push rod 802 and the linkage groove, a horizontal groove 804 is formed in the vertical plate 2 and slidably matched with the push rod 802, a first fixing groove 805 and a second fixing groove 806 are respectively formed in the horizontal groove 804, and a fixing hole 807 is formed in the rocker 709, and a fixing rod 808 is fixedly mounted on the mounting plate 801 and slidably matched with the fixing hole 807.

[0048] The through hole assembly 9 comprises a communication hole 901 formed in the mounting plate 801, a water pipe 902 is inserted in the water cavity 602 and communicated with the communication hole 901, and the water pipe 902 is communicated with the output end of the drain valve 604 through the communication hole 901.

[0049] By adopting the above technical scheme, when the rocker 709 needs to be rotated, the user can first push the push rod 802 upward, at this time the first spring 803 is compressed and has a restoring tendency, then after the push rod 802 is out of contact with the second fixed groove 806, the push rod 802 is driven to move the mounting plate 801, when the push rod 802 moves to the first fixed groove 805, the first spring 803 drives the push rod 802 to enter the first fixed groove 805, and the push rod 802 is fixed, at the same time, the mounting plate 801 drives the fixed rod 808 to be out of contact with the fixed hole 807 in the process of moving, at this time the user can normally rotate the rocker 709, when the adjustment of the second baffle 503 is completed, the user can push the push rod 802 upward again, and make the push rod 802 out of contact with the first fixed groove 805, then the push rod 802 and the mounting plate 801 drive the fixed rod 808 to be inserted into the fixed hole 807, after the fixed rod 808 is inserted into the fixed hole 807, the first spring 803 is stretched and drives the push rod 802 to be inserted into the second fixed groove 806, so that the position of the rocker 709 can be fixed, that is, the position of the first baffle 4 can be fixed, effectively avoiding that the gangue impacts the second baffle 503 to drive the vertical plate 2 to vibrate, so that the threaded rod 707 is slightly rotated, causing the position of the first baffle 4 and the second baffle 503 to deviate and affect the protection effect, and further improving the protection effect.

[0050] When the rocker 709 is fixed, the push rod 802 is located at the first fixed groove 805, at this time the communication hole 901 on the mounting plate 801 is not communicated with the water pipe 902, then when the device installation is completed and the rocker 709 is fixed, the push rod 802 is located at the second fixed groove 806, at this time the communication hole 901 on the mounting plate 801 is communicated with the water pipe 902, at this time the water flow in the water tank 601 can normally flow to the water cavity 602 through the drain valve 604, the communication hole 901 and the water pipe 902, so as to avoid that when the gangue baffle device is transported or installed, the water flow in the water tank 601 flows to the outside through the drain valve 604, causing water resource waste and affecting normal dust spraying.

[0051] As shown in Figure 5 The end of the fixed rod 808 close to the fixed hole 807 is tapered.

[0052] By adopting the above technical scheme, by making the end of the fixed rod 808 close to the fixed hole 807 tapered, the initial contact area of the fixed rod 808 and the fixed hole 807 can be reduced, so as to facilitate the insertion of the fixed rod 808 into the fixed hole 807.

[0053] As shown in Figure 4 The water cavity 602 is fixedly installed with an elastic film 10.

[0054] By adopting the technical scheme, after the water flow flows into the water cavity 602, the water flow will extrude the elastic film 10 and make the elastic film 10 deform, and then the elastic film 10 gradually shrinks as the water flow flows to the outside through the spray head 603, that is, by arranging the elastic film 10, it can be ensured that a large amount of water flow can normally flow into the water cavity 602, and the water flow can normally flow through the spray head 603 to continuously spray to the outside, and the spraying time can be further improved, thereby further improving the protection effect.

[0055] Method for use: when the gangue falls on the second gangue blocking plate 503, the second gangue blocking plate 503 will extrude the buffer spring 502 under the impact force of the gangue, at this time, the gangue can be buffered under the action of the second gangue blocking plate 503 and the buffer spring 502, so as to avoid the gangue from falling on the gangue blocking net and causing a large impact force to the gangue blocking net, so that the gangue blocking net is easy to be damaged and the protection effect is affected, and meanwhile, the metal air bag 501 is arranged to isolate the buffer spring 502 from the gangue, so as to avoid the gangue from being stuck on the buffer spring 502; when the gangue slides off the second gangue blocking plate 503, the buffer spring 502 stretches and drives the metal air bag 501 and the second gangue blocking plate 503 to reset, and in the process of resetting the metal air bag 501, air flow is sucked from the outside through the air inlet valve 605, and then in the process of compressing the metal air bag 501, the air flow in the metal air bag 501 flows into the water tank 601 through the air outlet valve 606 and the first air pipe 607, and in the process of air extraction and exhaust of the metal air bag 501, the impact of the gangue falling can be consumed; after the air flow flows to the water tank 601, the pressure in the water tank 601 increases, and then under the action of the pressure, the water flow in the water tank 601 flows into the water cavity 602 through the drain valve 604 and the through hole assembly 9, and sprays to the outside through the spray head 603 on the water cavity 602, so as to spray the dust; after the adjustment of the second gangue blocking plate 503 is completed, the user can push the push rod 802 upward again and make the push rod 802 out of contact with the first fixed slot 805, and then drive the fixed rod 808 to insert into the fixed hole 807 through the push rod 802 and the mounting plate 801, after the fixed rod 808 inserts into the fixed hole 807, the first spring 803 stretches and drives the push rod 802 to insert into the second fixed slot 806, so as to fix the position of the rocker 709, that is, to fix the position of the first gangue blocking plate 4; when the rocker 709 is fixed, the push rod 802 is located at the first fixed slot 805, at this time, the communication hole 901 on the mounting plate 801 is not communicated with the water pipe 902, then when the device is installed and the rocker 709 is fixed, the push rod 802 is located at the second fixed slot 806, at this time, the communication hole 901 on the mounting plate 801 is communicated with the water pipe 902, at this time, the water flow in the water tank 601 can normally flow into the water cavity 602 through the drain valve 604, the communication hole 901 and the water pipe 902, so as to avoid that when the gangue blocking device is transported or installed, the water flow in the water tank 601 flows to the outside through the drain valve 604.
