[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1 Figures 1 to 5 As shown, a transmission device for underground mining operations includes a top support slide rail 1, a transmission E-type bracket 2 slidably connected to the side of the top support slide rail 1, and an upper support roller assembly 4 rotatably connected to the side of the transmission E-type bracket 2. A lower support roller assembly 5 is arranged parallel below the upper support roller assembly 4. A conveyor belt 6 is provided on the upper end face of both the lower support roller assembly 5 and the upper support roller assembly 4. A rotating component 3 is provided at the connection between the upper support roller assembly 4 and the lower support roller assembly 5 and the transmission E-type bracket 2. The top support slide rail 1 includes a T-shaped slide rail 101, and a guide slide rod 103 with the same direction as the T-shaped slide rail 101 is arranged parallel to the side of the T-shaped slide rail 101. The transmission E-type bracket 2 includes a bracket side 201 that is slidably mounted on the side of the T-shaped slide rail 101. A lifting part 205 is provided on the side of the bracket side 201, and a rotating component 3 is mounted on the side end face of the lifting part 205.

[0018] Specifically, the transmission E-type bracket 2 also includes a support part 202 welded above the bracket side 201. The support part 202 is sleeved on the outside of the guide slide rod 103. A limiting end 207 is welded to the end of the bracket side 201, and two rollers 203 are rotatably installed on the side of the limiting end 207 near the groove in the middle of the T-shaped slide rail 101. Multiple connectors 102 are welded to the top of the T-shaped slide rail 101.

[0019] Furthermore, the T-shaped slide rail 101 is fixed to the top of the tunnel in the working area by the connector 102, and the guide slide rod 103 is also equipped with connecting accessories for fixing the guide slide rod 103.

[0020] Specifically, the transmission E-type bracket 2 also includes support plates 208 set on the upper and lower sides of the lifting part 205, and a lifting cylinder 204 is bolted to the top of the upper support plate 208. The telescopic end of the lifting cylinder 204 is fixedly connected to the lifting part 205, and a guide column 206 is set between the two support plates 208 and penetrates the interior of the lifting part 205.

[0021] Furthermore, the lifting cylinder 204 can drive the lifting part 205 to move up and down, thereby driving the upper support roller assembly 4 and the lower support roller assembly 5 installed on it to move up and down synchronously, so that the upper support roller assembly 4 and the lower support roller assembly 5 can be adapted to the height of the conveyor belt 6.

[0022] In use, the E-type transmission bracket 2 is slidably connected to the T-shaped slide rail 101 in the top support slide rail 1 through its bracket side 201, and is stably guided by the guide slide rod 103. After the lifting electric cylinder 204 is started, the lifting part 205 can be driven to move upward, which drives the upper support roller assembly 4 and the lower support roller assembly 5 to stick to the conveyor belt 6 upward.

[0023] In summary, with the E-type transmission bracket 2 in place, the operator can push or use an external drive device to move the entire E-type transmission bracket 2 along the top support slide rail 1, flexibly adjusting the working position. Furthermore, the conveyor belts 6 on the upper support roller assembly 4 and the lower support roller assembly 5 can fully meet the material transportation requirements.

[0024] Example 2: In addition to all the technical features included in Example 1, this example also includes: Specifically, the rotating assembly 3 includes a connector 301 fixed to the side end face of the lifting part 205. A transmission worm gear 303 is rotatably connected inside the connector 301, and one end of the transmission worm gear 303 is mounted on the inner wall of the connector 301 through a bearing.

[0025] Furthermore, two connectors 301 are provided, which are respectively connected to the upper support roller assembly 4 and the lower support roller assembly 5.

[0026] Specifically, the other end of the transmission worm 303 is fixed with an internal hexagonal screw head 304 embedded in the connector 301. An embedded hole 305 is provided at the connection between the internal hexagonal screw head 304 and the connector 301. A transmission worm wheel 302 is meshed and connected to the lower part of the transmission worm 303.

[0027] Furthermore, the transmission worm 303 and the transmission worm wheel 302 are selected as worm gear assemblies with self-locking properties.

[0028] Specifically, the upper support roller assembly 4 includes an upper support rod 401 rotatably connected to one of the connectors 301 via a bearing. A first support frame 404 is welded above the upper support rod 401. A middle idler roller 402 and a side idler roller 403 are arranged from the inside to the outside among the multiple first support frames 404.

[0029] Furthermore, the central idler roller 402 and the two sets of side idler rollers 403 form a U-shaped structure to ensure that the material does not scatter during the conveying process.

[0030] Specifically, the lower support roller assembly 5 includes a lower support rod 501 rotatably connected to another connector 301 via a bearing. A second support frame 503 is welded above the lower support rod 501. Two lower rollers 502 are arranged between the multiple second support frames 503, and the two sets of lower rollers 502 form a V-shaped structure.

[0031] Furthermore, the lower support roller assembly 5 and the upper support roller assembly 4 have different shapes to meet different material carrying requirements and prevent material spillage. When the middle idler roller 402, the side idler roller 403 and the lower idler roller 502 are damaged, they can be maintained individually without stopping the machine.

[0032] Specifically, the lower support rod 501 and the upper support rod 401 are respectively connected to two transmission worm gears 302, and the ends of the lower support rod 501 and the upper support rod 401 are installed inside the connector 301 through bearings.

[0033] Furthermore, the connector 301 has a hollow interior structure for mounting the transmission worm 303 and the transmission worm wheel 302, with the bearing embedded at the end of the connector 301.

[0034] In use, the transmission worm 303 in the rotating assembly 3 is manually or driven to rotate via the internal hexagonal screw head 304, which drives the transmission worm wheel 302 that meshes with it to rotate. This causes the upper support rod 401 or the lower support rod 501 connected to the transmission worm wheel 302 to rotate, ultimately achieving angle adjustment of the upper support rod 401 and the lower support rod 501 to ensure that the conveyor belt 6 remains taut. When not in use, the upper support rod 401 and the lower support rod 501 can be adjusted to be parallel to the horizontal plane for easy recycling of the conveyor belt 6.

[0035] In summary, the rotating component 3 can rotate the upper support rod 401 or the lower support rod 501, ensuring that the conveyor belt 6 remains taut during material transportation. When recycling the conveyor belt 6, the idler roller can be placed horizontally, away from the conveyor belt 6, making it convenient to recycle the conveyor belt 6.

[0036] The E-type support bracket 2 is slidably connected to the T-shaped slide rail 101 in the top support slide rail 1 via its support side 201, and is stably guided by the guide slide rod 103. The transmission worm gear 303 in the rotating assembly 3 is manually or driven to rotate via the internal hexagonal screw head 304, which drives the transmission worm wheel 302 that meshes with it to rotate, thereby causing the upper support rod 401 or the lower support rod 501 that is keyed to the transmission worm wheel 302 to rotate, and finally realizes the angle adjustment of the upper support rod 401 and the lower support rod 501. After the upper support roller assembly 4 and the lower support roller assembly 5 are perpendicular to the conveyor belt 6, the lifting cylinder 204 is activated. The lifting cylinder 204 drives the lifting part 205 to move upward, thereby driving the upper support roller assembly 4 and the lower support roller assembly 5 to press against the conveyor belt 6. The material can be transported through the conveyor belt 6. When it is necessary to inspect a certain roller, there is no need to stop the machine for maintenance.
