Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical equipment protection, in particular to a coal mine electromechanical equipment protection device. Background Art

[0002] In the process of coal mining, some electromechanical equipment will be used for mining work. There are many types of electromechanical equipment in coal mines. The roadheader is an extremely important mechanical equipment in coal mining, especially in the process of tunnel excavation. The roadheader integrates multiple functions such as rock breaking, rock loading, and rock transportation. It can continuously cut and crush the coal seam, and load and transport the crushed materials to achieve efficient tunnel excavation. Compared with the traditional drilling and blasting method, it has significant advantages such as fast excavation speed and good tunnel quality.

[0003] When a roadheader is mining, as the cutting head continues to mine deeper, large pieces of ore often fall down. The main part of the cutting part of the existing roadheader is only covered by a layer of iron shell, and the protection measures are weak. After the large ore blocks are cut and dropped, they may damage the core power part and accumulate on the plane of the cutting part, leaving safety hazards. For this reason, we propose a protective device for coal mine electromechanical equipment. Utility Model Content

By utilizing the coordinated structure of the pulley, rotating frame, transmission rod, roller, linkage rod, sleeve, etc., the coal blocks on the buffer plate can be smoothly pushed and dropped, thereby realizing the automatic transfer of the coal blocks and preventing the coal blocks from accumulating above the cutting part and affecting the normal operation of the roadheader.

[0013] 2. With the help of the rotating rod and the scraper rod, the utility model can clean the broken coal blocks on the surface of the cutting part when the buffer plate is moved by the gravity of the coal blocks, thereby ensuring the cleanliness of the surface of the cutting part, facilitating its subsequent normal operation and reducing the potential hidden dangers caused by the residual broken coal blocks.

The two long plates are rotatably connected, and the rotating frame 6 is rotatably connected to a pulley 7. The pulley 7 is composed of two upper and lower rollers and an inverted L-shaped plate. A slide rail 12 is fixedly installed on the side of the buffer plate 3, and the two rollers are respectively connected to the slide rail 12 The upper wall and the lower wall are in rolling contact to reduce friction resistance. The pulley 7 is rotatably connected to the transmission rod 8, and the transmission rod 8 is rotatably connected to the roller 9. The transmission rod 8 is also fixedly connected to the linkage rod 10. The linkage rod 10 is rotatably connected to the sleeve 11. The surface of the sleeve 11 is provided with concave and convex patterns. When the sleeve 11 contacts the coal block, the friction force can be reduced by self-rotation. A crushing barrel 15 is fixedly installed on the transport part of the tunneling machine 1. The crushing barrel 15 is used to receive large coal blocks. Crushing teeth 16 are provided in the crushing barrel 15. The crushing teeth 16 are fixedly mounted on the planetary loading mechanism of the tunneling machine 1 and rotate synchronously with the planetary loading mechanism. The crushing teeth 16 are composed of a connecting rod 161 and a plurality of crushing gears 162. The connecting rod 161 and the plurality of crushing gears 162 are fixedly connected.

[0023] Working principle: When a large coal block falls above the cutting part of the roadheader 1, the coal block is first blocked by the buffer plate 3 and its impact force is buffered. Due to the gravity of the large coal block, the large coal block will squeeze the spring 5 through the slider 4 on the buffer plate 3, and in the process of the buffer plate 3 moving downward, the pulley 7 will be subjected to force and roll in the slide rail 12 under the restriction of the rotating frame 6, thereby driving the transmission rod 8 to move horizontally, and the roller 9 will roll on the buffer plate 3 driven by the transmission rod 8. At the same time, the linkage rod 10 drives the sleeve 11 to move horizontally, and then pushes the large coal block from the buffer plate 3 and drops it; in the process of the buffer plate 3 moving downward under the gravity of the coal block, the buffer plate 3 will squeeze the rotating rod 13, and the rotating rod 13 is forced to push the scraper rod 14, and the scraper rod 14 moves horizontally under the restriction of the surface of the cutting part of the roadheader 1, and the scraper rod 14 pushes the broken coal blocks on the surface of the cutting part to move horizontally and then fall.

[0024] When large coal lumps fall from the buffer plate 3, the crushing barrel 15 will receive the large coal lumps, and then the crushing teeth 16 will squeeze the large coal lumps together with the cylinder wall of the crushing barrel 15 through rotation until the large coal lumps are broken and fall off from the crushing barrel 15, and then the star wheel loading structure will collect the broken coal lumps to the subsequent transportation equipment.
