Description

Technical Field

[0001] This utility model relates to a rock-blocking device, and more particularly to a rock-blocking device for an inclined belt conveyor. Background Technology

[0002] Inclined shaft belt conveyors are a common and essential transportation equipment in coal mine production, playing a crucial role in the continuous transportation of coal and gangue. During the transportation process, coal chunks and gangue inevitably roll and fall off the belt surface, and these rolling coal chunks and gangue are not easily stopped from continuing to fall, posing certain safety hazards to production.

[0003] Patent publication number CN209800018U discloses a gangue-blocking device for a scraper conveyor, comprising: a fixed bracket and a gangue-blocking plate. The fixed bracket and the gangue-blocking plate are hinged together by a hinge device, and a positioning device is provided between the fixed bracket and the gangue-blocking plate to fix their relative positions. The gangue-blocking device is designed with a flip-up structure; the gangue-blocking plate is erected when gangue blocking is needed and lowered when not needed for easy observation of the working face. While this patent facilitates the erection and dismantling of the gangue-blocking plate, after prolonged use, the continuous impact of coal gangue may cause deformation or damage to the plate, necessitating replacement. During the replacement of the gangue-blocking plate, if the conveyor does not stop running, there is a risk of coal gangue splashing out from the dismantling point, potentially causing personal injury and safety issues. However, if the conveyor is stopped to replace the baffle plate, it will directly affect the normal transportation operation of the coal mine. Utility Model Content

[0004] To overcome the risks of coal gangue splashing out from the disassembly point if the conveyor does not stop running during the replacement of the gangue baffle, and the disadvantage that stopping the conveyor to replace the gangue baffle would directly affect the normal transportation operation of the coal mine, this utility model provides a gangue baffle device for inclined shaft belt conveyors.

[0005] The technical solution is as follows: A rock-blocking device for an inclined belt conveyor includes a base, a support frame, and a protective isolation mechanism. Two support frames are provided, and the two support frames are respectively located on the left and right sides of the base. Each support frame has a protective isolation mechanism on its top. The protective isolation mechanism includes a fixing bolt, a mounting frame, and an isolation plate. The mounting frame is inserted into the support frame. A threaded hole is opened on one side of the support frame, and the fixing bolt fixes the mounting frame in the support frame through the threaded hole. The top of the mounting frame has at least two slots, one of which contains an isolation plate.

[0006] Optionally, it also includes a handle, with a handle provided on the top of the partition.

[0007] Optionally, it also includes a mounting bracket, a bearing seat, a mounting plate, a support bracket, a one-way plate, and a limiting rod. Multiple mounting brackets are provided between two support brackets, and several bearing seats are provided on the rear side of the mounting bracket. A mounting plate is provided between every two bearing seats. The mounting plate is hinged to the mounting bracket through the bearing seat. A one-way plate is fixed to the bottom of the mounting plate. The limiting rod is located on the rear side of the mounting bracket, and the one-way plate contacts the limiting rod.

[0008] Optionally, it also includes a screw and a support rod, one end of which is hinged to the upper part of the mounting frame, and the other end of which is fitted with a screw. The top of the support frame is provided with a threaded groove that matches the screw.

[0009] Optionally, it also includes nuts, with two nuts on the outside of the screw, located on the upper and lower sides of the strut respectively.

[0010] Optionally, it also includes a buffer sleeve, with the outer side of the limiting rod fitted with a buffer sleeve.

[0011] The beneficial effects of this utility model are: 1. The design of multiple slots on the top of the isolation plate and mounting frame of this utility model allows the isolation plate to be replaced without stopping the operation of the inclined conveyor, maintaining the continuous operation of the conveyor and avoiding production interruption due to machine stoppage for isolation plate replacement. Moreover, when replacing the isolation plate, even if the conveyor continues to work, the gangue will not splash out from the gap of the replaced isolation plate, reducing the possibility of accidents.

[0012] 2. The design of multiple one-way plates in this utility model ensures that even if some one-way plates are lifted when encountering sharp coal piles, the remaining one-way plates can still play a blocking role, thereby enhancing the overall stability and reliability of the system.

Detailed Implementation

[0018] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0019] A rock-blocking device for an inclined belt conveyor, such as Figures 1-3 As shown, the system includes a base 1, a support frame 9, and a protective isolation mechanism. There are two support frames 9, which are respectively located on the left and right sides of the base 1. The distance between the two support frames 9 is sufficient to accommodate the inclined conveyor 2. Each support frame 9 has a protective isolation mechanism on its top. The protective isolation mechanism includes a fixing bolt 13, a mounting frame 14, and an isolation plate 15. The top left and right sides of the support frame 9 have grooves. The mounting frame 14 is inserted into the grooves of the support frame 9. The side wall of the support frame 9 has a threaded hole. The fixing bolt 13 is threaded into the threaded hole and fixes the mounting frame 14 in the support frame 9 through the threaded hole. The top of the mounting frame 14 has two slots, one on the left and one on the right. One of the slots contains the isolation plate 15.

[0020] like Figure 4 As shown, it also includes a handle 16. The top of the isolation plate 15 is provided with a handle 16, which allows workers to remove the isolation plate 15 from the mounting frame 14.

[0021] like Figure 2 As shown, it also includes a mounting frame 3, a bearing 4, a mounting plate 5, a support frame 9, a one-way plate 6, and a limiting rod 7. Multiple mounting frames 3 are provided between two support frames 9. Several bearings 4 are provided on the rear side of the mounting frame 3. A mounting plate 5 is provided between every two bearings 4. The mounting plate 5 is hinged to the mounting frame 3 through the bearings 4. The bottom of the mounting plate 5 is fixed with a one-way plate 6 by bolts. The one-way plate 6 can rotate counterclockwise to allow raw coal to pass through. The limiting rod 7 is located on the rear side of the mounting frame 3. The limiting rod 7 can block the one-way plate 6 to prevent the gangue from rolling back when the one-way plate 6 rotates clockwise. The one-way plate 6 is in contact with the limiting rod 7.

[0022] like Figure 3 As shown, it also includes a screw 10 and a support rod 11. One end of the support rod 11 is hinged to the upper part of the mounting frame 14, and the other end of the support rod 11 is fitted with the screw 10. The top of the support frame 9 is provided with a threaded groove that matches the screw 10, and the screw 10 passes through the threaded groove on the support frame 9.

[0023] like Figure 3 As shown, it also includes nuts 12. Two nuts 12 are provided on the outside of the screw 10. The two nuts 12 are located on the upper and lower sides of the support rod 11, respectively. By tightening the nuts 12, the support rod 11 can be firmly fixed on the screw 10.

[0024] like Figure 2As shown, it also includes a buffer sleeve 8. The buffer sleeve 8 is sleeved on the outside of the limiting rod 7. The buffer sleeve 8 can alleviate the impact force generated when the one-way plate 6 rotates clockwise and collides with the limiting rod 7.

[0025] Install the inclined conveyor 2 between two support frames 9, then start the inclined conveyor 2 and pour raw coal into the inlet end of the inclined conveyor 2. During the process of transporting the raw coal from the inlet end to the outlet end of the inclined conveyor 2, hard and heavy gangue mixed in the raw coal may splash out from the inclined conveyor 2. The isolation plates 15 on both sides of the support frames 9 can block these flying gangue in the inclined conveyor 2, preventing injury from flying gangue. When replacing the isolation plates 15 that are damaged after long-term operation, since there are two slots on the top of the mounting frame 14 for placing the isolation plates 15, it is possible to first... The new isolation plate 15 is inserted into the mounting frame 14 through the empty slot, and the old isolation plate 15 is removed from the mounting frame 14 using the handle 16. This allows the replacement of the isolation plate 15 without stopping the operation of the inclined conveyor 2. This not only allows the inclined conveyor 2 to continue operating, avoiding production interruptions due to the replacement of the isolation plate 15, thus improving overall work efficiency, but also prevents accidents caused by gangue splashing out from the gaps in the replaced isolation plate 15 while the inclined conveyor 2 continues to operate. Alternatively, a mounting frame 3 can be installed between the two support frames 9 during the transportation of raw coal. Pushing the one-way plate 6 on the mounting frame 3 and passing it through the bottom of the mounting frame 3, the limiting rod 7 is installed on the rear side of the mounting frame 3. When the rolling raw coal hits the one-way plate 6, the limiting rod 7 can prevent the one-way plate 6 from being pushed clockwise, thus preventing the raw coal from passing through the one-way plate 6. This effectively prevents the gangue in the raw coal from rolling back, ensuring the safety of the transportation process. When the raw coal pile has different heights, especially when encountering sharp raw coal piles, when the raw coal pile passes through the mounting frame 3, a single one-way plate 6 will be completely lifted. When a single one-way plate 6 is lifted, since the sides of the sharp raw coal pile are open, the gangue behind the mounting frame 3 is easily... The coal rolls out from both sides of the sharp coal pile, causing it to roll backwards. The design of multiple one-way plates 6 ensures that even if some one-way plates 6 are lifted, the remaining one-way plates 6 can still act as a barrier, effectively preventing the coal from rolling backwards. If the isolation plate 15 is hit by a large piece of coal, the fixing bolts 13 may not be able to withstand the impact force, causing the mounting frame 14 to loosen, deform, or be damaged. The mounting frame 14 is connected to the support frame 9 by the strut 11 to form a stable triangular structure. This structure can effectively resist the impact force. The support force of the strut 11 can be adjusted by adjusting the two nuts 12.

[0026] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
