Description

Technical Field

[0001] This utility model relates to the field of coal conveyor belt technology, specifically to a tear prevention device for a mining coal conveyor belt. Background Technology

[0002] During coal transportation, coal conveyor belts in mines are prone to tearing due to foreign objects (such as large stones or metal parts) mixed in with the material. A tearing accident not only damages the equipment but can also lead to production interruptions, increased maintenance costs, and safety hazards.

[0003] Existing mine coal conveyor belts generally rely on manual periodic inspections, which is not only time-consuming and labor-intensive, but also unable to detect foreign objects or abnormalities on the belt in a timely manner, making it difficult to guarantee the accuracy and timeliness of the inspection.

[0004] Therefore, a tear prevention device for mine coal conveyor belts that is easy to install and use is needed. Utility Model Content

[0005] The technical problem this invention aims to solve is that manual inspection is inefficient and it is difficult to guarantee the accuracy and timeliness of the inspection. This invention provides a tear prevention device for mine coal conveyor belts that is easy to install and use.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a tear prevention and control device for a coal conveyor belt, comprising a coal conveyor belt body and a tear prevention and control mechanism;

[0007] The tear prevention mechanism includes a mounting plate, a camera, an infrared sensor, and a control panel. There is a pair of mounting plates, which are fixed to both sides of the main body of the coal conveyor belt by the mounting mechanism. The top of each mounting plate is connected to an upper support plate located directly above the main body of the coal conveyor belt. The camera is detachably mounted on the upper support plate and faces the main body of the coal conveyor belt.

[0008] The bottom ends of the two mounting plates are respectively connected to lower support plates extending to the bottom of the main body of the coal conveyor belt. A connecting plate is detachably connected between the two lower support plates. Infrared sensors are embedded in the top surface of the connecting plate and multiple sensors are evenly distributed.

[0009] After the control panel is bolted to the side wall of the coal conveyor belt, it is connected with the camera and infrared sensor. The control panel is equipped with an audible and visual alarm.

[0010] As an improvement, the mounting mechanism includes through holes, threaded mounting holes, and mounting bolts;

[0011] Two mounting plates are provided with through holes. After the mounting bolts pass through each through hole, they are threaded into the mounting threaded holes on the outer wall of the coal conveyor belt. The split structure makes it easy to install on different coal conveyor belts and quickly realize the installation operation.

[0012] As an improvement, sliding grooves are provided on both sides of the two mounting plates. Each upper support plate and lower support plate is connected to a pair of support rods that slide in the sliding grooves. After each upper support plate and lower support plate slides to different positions in the sliding grooves, they are fixed by a positioning mechanism. This can be adjusted as needed, thus making it suitable for coal conveyor belts of different specifications.

[0013] As an improvement, the positioning mechanism includes a positioning plate, a positioning hole, and a positioning threaded hole;

[0014] Each upper and lower support plate has a positioning plate that slides close to the mounting plate between its two support rods. The positioning plate has positioning holes, and bolts pass through the positioning holes to engage with different positioning threaded holes on the mounting plate. Multiple positioning threaded holes are evenly arranged along the sliding direction of the upper and lower support plates to quickly achieve positioning operations.

A magnetic plate is provided on the top surface of the upper support plate to facilitate disassembly and maintenance.

[0016] As an improvement, an L-shaped plate slides on the bottom surface of the connecting plate, and there is a pair of mirror images. After the connecting plate is placed on the two lower support plates, the two L-shaped plates are pushed to a horizontal position to fit tightly against the bottom surface of the lower support plate. Fixing screw holes are opened on the L-shaped plates to facilitate the maintenance of infrared sensors, and the position of the L-shaped plates can be easily adjusted as needed, thus making it suitable for coal conveyor belts of different specifications.

[0017] As an improvement, a scraper is also included. A scraper is fixedly installed on the top surface of the connecting plate. After the positioning mechanism fixes the position of the two lower support plates, the scraper is in close contact with the belt surface of the coal conveyor body, effectively cleaning foreign objects from the belt surface and reducing the risk of tearing.

[0018] As an improvement, the control panel is connected to the camera and infrared sensor via a wireless transmission device to enable real-time data transmission.

[0019] The advantages of this utility model compared with the prior art are as follows:
