Description

Technical Field

[0001] This utility model relates to the field of gangue spraying dust suppression technology, specifically to a supporting system for gangue filling in underground coal mine tunnel boring machines. Background Technology

[0002] In modern coal mining operations, tunnel boring machines (TBMs) are key equipment for driving mining progress due to their efficient and stable tunneling performance. However, a large amount of gangue is generated during the tunneling process. This gangue needs to be transported to the underground filling area through a conveying system to complete the task of supporting the goaf and maintaining safe production in the mine.

[0003] In existing technologies, gangue is typically transported using belt conveyors. However, during transport, the gangue generates a large amount of fine dust due to friction, collisions, and contact with the conveying equipment. This dust permeates the underground tunnels, and workers inevitably inhale it. Prolonged exposure to such an environment can easily lead to serious respiratory diseases such as pneumoconiosis and silicosis.

[0004] In the current technology, the common method to deal with dust problems during the transportation of gangue is to spray water to suppress dust. Multiple spray heads are installed at the top of the belt conveyor to spray the gangue to suppress dust and achieve the purpose of adsorbing dust and suppressing dust. However, the spray head angle is fixed, which makes it difficult to fully cover the gangue transportation area and easily creates dust suppression dead zones, which may cause some dust to still escape into the air. Utility Model Content

[0005] This utility model proposes a supporting system for underground backfilling of gangue in coal mine tunnel boring machines, which solves the problem of dust suppression dead zones that are easily generated during the dust suppression process of spraying gangue with spray heads in the existing technology.

[0006] The technical solution of this utility model is as follows: a coal mine shield tunneling machine gangue underground filling system, including a first belt conveyor, a second belt conveyor, a support cover, spray pipes, a water supply mechanism, and a swing mechanism. The second belt conveyor is located on one side of the first belt conveyor, and one end of the second belt conveyor is fixedly connected to the first belt conveyor. The support cover is located on one side of the second belt conveyor, and two support plates are fixedly arranged between the support cover and the second belt conveyor. Multiple spray pipes are rotatably arranged inside the support cover, and multiple spray heads are connected to the bottom sidewall of the spray pipes. The water supply mechanism is located inside the support cover for supplying water to the spray pipes. The swing mechanism is located between the support cover and the spray pipes for driving the spray heads to swing around the spray pipes.

[0007] Preferably, the water supply mechanism includes:

[0008] The first cavity is formed inside the support cover;

[0009] The spray pipe extends into the first cavity near the side wall of the first cavity, and the spray pipe is rotatably and sealingly connected to the side wall of the first cavity.

[0010] A water supply pipe is installed through the side wall of the first cavity.

[0011] Furthermore, the swing mechanism includes:

[0012] The second cavity is formed inside the support cover;

[0013] The end of the spray pipe near the second cavity is sealed and extends into the second cavity;

[0014] An adjusting plate is fixedly installed on the bottom side wall of the spray pipe;

[0015] An angle adjustment mechanism is disposed in the second cavity and is used to adjust the angle of the adjustment plate relative to the spray pipe.

[0016] Furthermore, the angle adjustment mechanism includes:

[0017] An adjusting disc is rotatably mounted on the side wall of the second cavity, located on one side of the adjusting plate.

[0018] An adjustment through hole is provided on the adjustment plate;

[0019] An adjusting column is fixedly installed at an eccentric position on the adjusting disc, and the adjusting column extends into the adjusting through hole;

[0020] A drive mechanism is disposed between the support cover and the adjustment disc, and is used to drive the plurality of adjustment discs to rotate.

[0021] Furthermore, the drive mechanism includes:

[0022] The third cavity is opened on one side of the second cavity, and the side wall of the third cavity is rotatably provided with a first bevel gear on one side of the adjusting disk;

[0023] A drive rod is rotatably disposed within the third cavity. Multiple second bevel gears are coaxially and fixedly disposed on the drive rod, and the second bevel gears mesh with the adjacent first bevel gears.

[0024] A first motor is mounted on the support cover, and the output end of the first motor is fixedly connected to the drive rod.

[0025] Based on the above scheme, a rubber pad is fixedly installed on the side wall of the adjusting column.

[0026] The working principle and beneficial effects of this utility model are as follows:

[0027] 1. In this utility model, by setting up a second belt conveyor, a support cover and a spray pipe, before the gangue is transported by the first belt conveyor, the gangue can be placed on the second belt conveyor for dust suppression spraying. Then, the gangue is transferred to the surface of the first belt conveyor for transportation by the operation of the second belt conveyor, thereby avoiding the gangue spraying process from having a significant impact on the transportation efficiency of the gangue.

[0028] 2. In this utility model, by setting up an angle adjustment mechanism, the operation of the drive mechanism can drive the adjustment plate to rotate. At the same time, the rotation of the adjustment plate drives the adjustment column to move around the adjustment plate. Then, the pressure of the adjustment column on the positioning through hole drives the adjustment plate and the spray pipe to reciprocate the angle. Thus, the angle of the spray head on the spray pipe can be changed to spray the gangue under the support cover in a comprehensive manner, thereby avoiding dust dead corners.

[0029] 3. In this utility model, through the operation of the drive mechanism, the operation of the first motor can drive the drive column and the second bevel gear to rotate, thereby facilitating the synchronous rotation of multiple adjustment discs through the meshing of the second bevel gear and the first bevel gear;

[0030] 4. In this utility model, the arrangement of the second belt conveyor, support cover, spray pipe, water supply mechanism and swing mechanism facilitates the comprehensive spraying of gangue on the surface of the second belt conveyor by the swinging of the spray head, thereby solving the problem of dust suppression dead zones that are easily generated during the dust suppression process of spraying gangue with the spray head in the prior art.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0040] like Figures 1-6 As shown in the figure, this embodiment proposes a coal mine tunnel boring machine gangue underground filling system, including a first belt conveyor 1, a second belt conveyor 2, a support cover 3, spray pipes 4, a water supply mechanism, and a swing mechanism. The second belt conveyor 2 is located on one side of the first belt conveyor 1, and one end of the second belt conveyor 2 is fixedly connected to the first belt conveyor 1. The support cover 3 is located on one side of the second belt conveyor 2, and two support plates are fixedly installed between the support cover 3 and the second belt conveyor 2. Multiple spray pipes 4 are rotatably installed inside the support cover 3, and multiple spray heads 5 are connected to the bottom side wall of the spray pipes 4. The water supply mechanism is located inside the support cover 3 for supplying water to the spray pipes 4. The swing mechanism is located between the support cover 3 and the spray pipes 4 for driving the spray heads 5 to swing around the spray pipes 4.

[0041] Reference Figure 3 and Figure 4 The water supply mechanism includes a first cavity 6 and a water supply pipe 7. The first cavity 6 is located inside the support cover 3. The spray pipe 4 extends into the first cavity 6 near the side wall of the first cavity 6. The spray pipe 4 is rotatably and sealed to the side wall of the first cavity 6. The water supply pipe 7 is installed through the side wall of the first cavity 6. Specifically, the operator can supply water to the first cavity 6 and the spray pipe 4 through the water supply pipe 7, and then spray the gangue with the spray head 5 to reduce dust.

[0042] Reference Figures 4-6The swing mechanism includes a second cavity 8, an adjusting plate 9, and an angle adjusting mechanism. The second cavity 8 is located inside the support cover 3. One end of the spray pipe 4 near the second cavity 8 is sealed and extends into the second cavity 8. The adjusting plate 9 is fixedly mounted on the bottom side wall of the spray pipe 4. The angle adjusting mechanism is located inside the second cavity 8 and is used to adjust the angle of the adjusting plate 9 relative to the spray pipe 4. The angle adjusting mechanism includes an adjusting disc 10, an adjusting through hole 11, an adjusting column 12, and a driving mechanism. The adjusting disc 10 is rotatably mounted on the side wall of the second cavity 8, located on one side of the adjusting plate 9. The adjusting through hole 11 is located on the adjusting plate 9, and the adjusting column 12 is fixedly mounted on the adjusting disc 10. In an eccentric position, the adjusting column 12 extends into the adjusting through hole 11. The driving mechanism is set between the support cover 3 and the adjusting plate 10 to drive multiple adjusting plates 10 to rotate. A rubber pad is fixedly installed on the side wall of the adjusting column 12. Specifically, the operation of the driving mechanism can drive the adjusting plate 10 to rotate. At the same time, the rotation of the adjusting plate 10 drives the adjusting column 12 to move around the adjusting plate 10. Then, the squeezing of the positioning through hole by the adjusting column 12 drives the adjusting plate 9 and the spray pipe 4 to reciprocate the angle. Thus, the angle of the spray head 5 on the spray pipe 4 can be changed to spray the gangue below the support cover 3 comprehensively, thereby avoiding dust dead zones.

[0043] Reference Figure 5 The drive mechanism includes a third cavity 13, a drive rod 15, and a first motor 17. The third cavity 13 is located on one side of the second cavity 8. A first bevel gear 14 is rotatably mounted on the side wall of the third cavity 13 on one side of the adjustment disk 10. The drive rod 15 is rotatably mounted inside the third cavity 13. Multiple second bevel gears 16 are coaxially and fixedly mounted on the drive rod 15. The second bevel gears 16 mesh with the adjacent first bevel gears 14. The first motor 17 is mounted on the support cover 3. The output end of the first motor 17 is fixedly connected to the drive rod 15. Specifically, the operation of the first motor 17 can drive the drive rod and the second bevel gears 16 to rotate, thereby facilitating the synchronous rotation of multiple adjustment disks 10 through the meshing of the second bevel gears 16 and the first bevel gears 14.

[0044] Working principle: During use, the operator first places the gangue on the surface of the second belt conveyor 2 using existing conveying devices such as excavators or loaders. Then, the second belt conveyor 2 transports the gangue to the surface of the first belt conveyor 1. During this process, the operator can supply water to the first cavity 6 and the spray pipe 4 through the water supply pipe 7, and then spray the gangue with the spray head 5 to reduce dust. At the same time, the operator controls the first motor 17 to work. The operation of the first motor 17 can drive the drive column and the second bevel gear 16 to rotate, so that the meshing of the second bevel gear 16 and the first bevel gear 14 can drive multiple adjusting discs 10 to rotate synchronously. During the rotation of the adjusting discs 10, the rotation of the adjusting discs 10 drives the adjusting column 12 to move around the adjusting discs 10. Then, the squeezing of the positioning through hole by the adjusting column 12 causes the adjusting plate 9 and the spray pipe 4 to change the angle back and forth. Thus, the angle change of the spray head 5 on the spray pipe 4 can be used to spray the gangue under the support cover 3 comprehensively, thereby avoiding dust suppression dead spots.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
