Description

Technical Field

[0001] This utility model relates to the field of coal mine support technology, specifically to an installation device for a mesh fence used in coal mine support. Background Technology

[0002] Coal mine support mesh is a key support material used in coal mine roadways, working faces, and tunnels to reinforce the roof and sidewalls. After being laid, it can fit closely to the roadway walls and roof, effectively preventing rock fragments from falling and improving the support effect.

[0003] In existing technologies, when installing support mesh on the top of a coal mine tunnel, workers usually need to lift the support mesh and manually hold it up before another worker can operate the installation. This requires at least two people to work together, which increases labor costs and time. In addition, the mine environment is narrow and the support mesh is heavy, so manual support may cause slips, collisions, or other injuries due to unstable posture.

[0004] In view of this, it is necessary to propose an installation device for coal mine support mesh to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0005] The purpose of this utility model is to provide an installation device for a coal mine support mesh, in order to solve the problems mentioned in the background art, which usually require two people to cooperate when installing support mesh on the top of a coal mine tunnel, which increases labor costs, and the support mesh is heavy, which may cause slips, collisions and other injuries due to unstable posture when manually supporting it.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an installation device for a coal mine support mesh, comprising a base and a coal mine support mesh, four universal wheels symmetrically installed below the base, a support frame installed above the base, a support structure connected to the support frame, two axle seats symmetrically installed above the base, a height adjustment structure connected to the two axle seats, a worm gear connected to the support structure, and a deflection structure connected to the worm gear.

[0007] Preferably, the support structure includes an adjusting frame, which is slidably installed inside the support frame. A movable frame is rotatably installed at one end of the adjusting frame. Several guide rods are slidably installed inside the movable frame. A bracket is installed at one end of each guide rod, and the coal mine support mesh is in contact with the bracket.

[0008] Preferably, a spring is slidably sleeved on the guide rod, with the two ends of the spring respectively installed between the movable frame and the bracket.

[0009] Preferably, a stop block is installed at one end of the guide rod, and the stop block is located below the movable frame.

[0010] Preferably, the guide rod has a guide groove inside, and a guide block is slidably installed in the guide groove. The guide block is installed on the inner wall of the movable frame.

[0011] Preferably, the height adjustment structure includes a bidirectional lead screw, which is rotatably installed inside two bearing seats. A geared motor is installed on one side of the corresponding bearing seat, and the output end of the geared motor is installed on the bidirectional lead screw. Two linkage slides are symmetrically threaded on the bidirectional lead screw. Both linkage slides are slidably installed above the base, and connecting rods are rotatably installed on both linkage slides. One end of each connecting rod is rotatably installed on both sides of the adjustment frame.

[0012] Preferably, the deflection structure includes a second geared motor, which is mounted on one side of the adjusting frame. The output end of the second geared motor is mounted on a worm gear, which is rotatably mounted inside the adjusting frame. A worm wheel is mounted on the inner wall of the movable frame, and the worm wheel meshes with the worm gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In use, the coal mine support mesh can be placed on the bracket. The combination of the base, support frame and adjustment frame can provide auxiliary support for the coal mine support mesh, so that the construction personnel do not need to manually hold the coal mine support mesh for operation, saving labor. According to the different sizes of the mine, the support height of the coal mine support mesh can be adjusted by turning on the reduction motor, so that it can be adjusted according to the height of the coal mine, ensuring that the coal mine support mesh can fit with the top of the mine, which is convenient for its installation.

[0015] (2) By turning on the geared motor, the angle between the movable frame and the bracket can be finely adjusted, thereby changing the support angle of the coal mine support mesh, so that it can be finely adjusted according to the curvature of the top side of the coal mine tunnel, thereby further improving the fit between the coal mine support mesh and the tunnel when supporting the coal mine support mesh.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: an installation device for a coal mine support mesh, including a base 100 and a coal mine support mesh 101. Four universal wheels 102 are symmetrically installed below the base 100. A support frame 200 is installed above the base 100, and a support structure is connected to the support frame 200. The support structure can be used to provide support for the coal mine support mesh 101, avoiding the need for workers to hold it by hand. Two bearing seats 300 are symmetrically installed above the base 100, and a height adjustment structure is connected to the two bearing seats 300. The height adjustment structure can be used to adjust the support height of the coal mine support mesh 101. A worm gear 400 is connected to the support structure, and a deflection structure is connected to the worm gear 400. The deflection structure is used to fine-tune the angle of the coal mine support mesh 101.

[0025] Furthermore, the support structure includes an adjusting frame 201, which is slidably installed inside the support frame 200. A movable frame 202 is rotatably installed at one end of the adjusting frame 201. Several guide rods 203 are slidably installed inside the movable frame 202. A bracket 204 is installed at one end of each guide rod 203. The coal mine support mesh 101 is in contact with the bracket 204. In use, the coal mine support mesh 101 can be placed on several brackets 204. The support frame 200, adjusting frame 201, and bracket 204 can provide support for it.

[0026] Furthermore, a spring 205 is slidably sleeved on the guide rod 203. The two ends of the spring 205 are respectively installed between the movable frame 202 and the bracket 204. Since there are certain pits and depressions above the coal mine tunnel, when the movable frame 202 continues to rise, the bracket 204 will be squeezed by the inner wall of the tunnel, thus compressing the spring 205. Under the action of the guide rod 203 and the spring 205, the bracket 204 can slide and adapt according to the degree of pits and depressions at the top of the tunnel.

[0027] Furthermore, a stop 206 is installed at one end of the guide rod 203. The stop 206 is located below the movable frame 202. The stop 206 can prevent the guide rod 203 from falling out of the movable frame 202 during the sliding process.

[0028] Furthermore, a guide groove 207 is provided inside the guide rod 203, and a guide block 208 is slidably installed in the guide groove 207. The guide block 208 is installed on the inner wall of the movable frame 202. When the guide rod 203 slides, it can slide on the guide block 208 through the guide groove 207. The setting of the guide groove 207 and the guide block 208 can limit the angle of the guide rod 203 and prevent the bracket 204 and the guide rod 203 from rotating and shifting.

[0029] Example 2: Figure 1 To facilitate adjustment of the support height of the coal mine support mesh 101 according to the mine tunnel height, a height adjustment structure is provided. This structure includes a bidirectional lead screw 301, which is rotatably mounted inside two bearing seats 300. A geared motor 302 is mounted on one side of each bearing seat 300, and the output end of the geared motor 302 is mounted on the bidirectional lead screw 301. Two symmetrically threaded linkage slides 303 are fitted onto the bidirectional lead screw 301, and both linkage slides 303 are slidably mounted above the base 100. Two linkage slides 303 are rotatably mounted with connecting rods 304. One end of each connecting rod 304 is rotatably mounted on both sides of the adjusting frame 201. Turning on the geared motor 302 can drive the bidirectional lead screw 301 to rotate. When the bidirectional lead screw 301 rotates, it can drive the two linkage slides 303 to move, so that the moving linkage slides 303 push the adjusting frame 201 to slide and rise inside the support frame 200 through the connecting rods 304. This causes the adjusting frame 201 to drive the movable frame 202 and the bracket 204 to rise. The remaining features are the same as in Embodiment 1.

[0030] Example 3: As Figure 2-3To facilitate fine-tuning of the angle of the coal mine support mesh 101 according to the curvature of the mine wall, a deflection structure is arranged. The deflection structure includes a second geared motor 401, which is installed on one side of the adjusting frame 201. The output end of the second geared motor 401 is installed on the worm gear 400, which is rotatably installed inside the adjusting frame 201. A worm wheel 402 is installed on the inner wall of the movable frame 202, and the worm wheel 402 meshes with the worm gear 400. By turning on the second geared motor 401, the worm gear 400 can be driven to rotate. The rotating worm gear 400 can drive the movable frame 202 to rotate on the adjusting frame 201 through meshing with the worm wheel 402, thereby causing the guide rod 203, bracket 204 and the supported coal mine support mesh 101 to tilt. The remaining features are the same as in Embodiment 1.

[0031] The working principle is as follows: During use, the coal mine support mesh 101 can be placed on several brackets 204, which provide support. Then, the geared motor 302 is turned on, driving the bidirectional lead screw 301 to rotate. The connection between the bidirectional lead screw 301 and the bearing 300 and support frame 200 can be made into a smooth surface to ensure that the bidirectional lead screw 301 can rotate normally within the bearing 300. The remaining two ends of the bidirectional lead screw 301 can be provided with threads facing opposite directions, and each thread is adapted to two linkage slides 303. Thus, when the bidirectional lead screw 301 rotates, it can drive the two linkage slides 303 to move and approach each other. The moving linkage slides 303 will drive one end of the connecting rod 304 to rotate and move... The movement causes the other end of the connecting rod 304 to push the adjusting frame 201 to slide and rise inside the support frame 200. This causes the adjusting frame 201 to drive the movable frame 202 and the bracket 204 to rise, which in turn drives the coal mine support mesh 101 to rise and adhere to the top of the coal mine tunnel. Since there are some pits and depressions above the coal mine tunnel, when the movable frame 202 continues to rise, the bracket 204 will be squeezed by the inner wall of the tunnel, causing the guide rod 203 to slide inside the movable frame 202. At the same time, the bracket 204 will compress the spring 205. Under the action of the guide rod 203 and the spring 205, the bracket 204 can slide and adapt according to the degree of pits and depressions at the top of the tunnel, improving the adhesion effect between the coal mine support mesh 101 and the top of the tunnel.

[0032] The universal wheels 102 allow the base 100 to be moved within the scaffolding or mine shaft to adjust its position. Activating the geared motor 401 drives the worm gear 400 to rotate. The rotating worm gear 400, through engagement with the worm wheel 402, causes the movable frame 202 to rotate on the adjusting frame 201, thereby tilting the guide rod 203, bracket 204, and the supported coal mine support mesh 101. This allows for fine-tuning of the angle of the coal mine support mesh 101 to match the curvature of the mine wall. During adjustment, it must be ensured that the coal mine support mesh 101 does not detach from the bracket 204 after tilting.

[0033] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
