Description

Technical Field

[0001] The utility model belongs to the technical field of mechanized mining and transportation equipment for coal mines, in particular to a large depression angle mining and transportation device for coal. Background Art

[0002] Mechanized mining coal face transportation equipment is one of the important parts in coal mine production. It plays an important role in transporting coal and running the coal mining machine, and directly affects whether the coal mining face can operate normally. With the advancement of technology, the future coal mining machinery and equipment will also develop in the direction of intelligence and automation, further improving the technical level of the coal mining industry.

[0003] At present, a large-angle mining process is used for steeply inclined soft-top and soft-bottom working faces. In the working condition where materials cannot flow by themselves, traditional scraper conveyors cannot meet the requirements of material transportation. Moreover, running in an inclined state is not conducive to safe production, reduces the working efficiency of the equipment, directly affects the production capacity of coal mine transportation, and affects the actual work. Therefore, a large-angle mining and coal transportation device is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the traditional scraper conveyor cannot meet the requirements of material transportation under the working condition that the material cannot slide by itself, and to propose a large-angle mining and transportation device for coal.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a large-angle coal mining and transportation device, including a tail frame, a fixed frame is provided on the upper surface of the tail frame, a tensioning cylinder is provided on the fixed frame, a tensioning sprocket is provided on the side wall of the tail frame, a bearing seat is provided on the side wall of the tensioning sprocket, and the side wall of the bearing seat is rotatably connected to one end of the tensioning cylinder through a short shaft.

[0006] As a further description of the above technical solution:

[0007] A guide path is provided on the outer wall of the tail frame, and a slideway is provided inside the guide path.

[0008] As a further description of the above technical solution:

[0009] A fixed block is provided in the slideway of the guide machine way, and a plate chain is provided at one end of the fixed block.

[0010] As a further description of the above technical solution:

[0011] A lining block is provided inside the guide track, and a scraper is provided at one end of the lining block.

[0012] As a further description of the above technical solution:

[0013] A cover plate is installed on the outer wall of the guide track through bolt threads, and the outer surface of the tensioning sprocket is meshed and connected with the plate chain.

[0014] As a further description of the above technical solution:

[0015] A driving sprocket is provided at one end of the guide track, and the outer surface of the driving sprocket is meshed and connected with the plate chain.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. In the utility model, a tensioning oil cylinder is provided. At this time, the tensioning oil cylinder on the tail frame adjusts the running tensioning sprocket. When the leaf chain is too loose, the tensioning oil cylinder extends to one side, and the tensioning oil cylinder pushes the tensioning sprocket to move. When the tensioning oil cylinder extends, the tensioning sprocket moves toward the tight side of the leaf chain, thereby increasing the tensioning force of the leaf chain. Conversely, when the leaf chain is too tight, the tensioning oil cylinder will retract, and then the tensioning oil cylinder will drive the tensioning sprocket to move toward the loose side, thereby reducing the tensioning force of the leaf chain. By adjusting the tension of the equipment, it is helpful to realize the transportation of coal that cannot slide naturally near the coal wall side during steeply inclined and large-angle mining, so that the coal can be transported out in a timely and effective manner, thereby improving the transportation efficiency of the coal.

[0018] 2. In the utility model, by providing a cover plate, the return scraper and plate chain are protected under the protection of the cover plate on the guide machine way, and the coal is continuously transported by the scraper and plate chain, which helps to protect the plate chain and scraper from external factors, reduce wear and damage, thereby extending the service life of the equipment and realizing continuous transportation of scraped coal.

[0026] A guide path 4 is provided on the outer wall of the tail frame 1, a slide is provided inside the guide path 4, a fixed block 8 is provided inside the slide of the guide path 4, a plate chain 7 is provided at one end of the fixed block 8, a lining block 9 is provided inside the guide path 4, and a scraper 5 is provided at one end of the lining block 9.

[0027] The specific implementation method is as follows: the motor then drives the driving sprocket 6 on the guide machine path 4 to rotate, and the driving sprocket 6 drives the tensioning sprocket 3 to rotate through the plate chain. At this time, the plate chain 7 starts to circulate, and the plate chain 7 drives the scraper 5 to rotate synchronously. At this time, the tensioning cylinder 2 on the tail frame 1 adjusts the running tensioning sprocket 3 to facilitate the smooth operation of the equipment. When the plate chain 7 is too loose, the tensioning cylinder 2 extends to one side, and the tensioning cylinder 2 pushes the tensioning sprocket 3 to move. When the tensioning cylinder 2 extends, the tensioning sprocket 3 moves toward the tight side direction of the plate chain 7, thereby increasing the tensioning force of the plate chain 7. Conversely, when the plate chain is too tight, the tensioning cylinder 2 will retract, and then drive the tensioning sprocket 3 to move toward the loose side direction through the tensioning cylinder 2, thereby reducing the tensioning force of the plate chain 7.

[0028] A cover plate 10 is installed on the outer wall of the guide machine path 4 through bolt threads, the outer surface of the tensioning sprocket 3 is meshed with the plate chain 7, and a driving sprocket 6 is provided at one end of the guide machine path 4, and the outer surface of the driving sprocket 6 is meshed with the plate chain 7.

[0029] The specific implementation method is: under the protection of the cover plate 10 on the guide machine way 4, the return scraper 5 and the plate chain 7 are protected to improve the operating efficiency of the equipment, and then the coal is continuously transported through the scraper 5 and the plate chain 7.

[0030] Working principle: When coal transportation begins, the power supply is first started to drive the equipment to run, and then the motor drives the driving sprocket 6 on the guide machine path 4 to rotate. The driving sprocket 6 drives the tensioning sprocket 3 to rotate through the leaf chain. At this time, the leaf chain 7 starts to circulate, and the leaf chain 7 drives the scraper 5 to rotate synchronously. At this time, the tensioning cylinder 2 on the tail frame 1 adjusts the running tensioning sprocket 3. When the leaf chain 7 is too loose, the tensioning cylinder 2 extends to one side, and the tensioning cylinder 2 pushes the tensioning sprocket 3 When the tensioning cylinder 2 is extended, the tensioning sprocket 3 moves toward the tight side of the leaf chain 7, thereby increasing the tensioning force of the leaf chain 7. Conversely, when the leaf chain is too tight, the tensioning cylinder 2 will be retracted, and then the tensioning sprocket 3 will be driven by the tensioning cylinder 2 to move toward the loose side, thereby reducing the tensioning force of the leaf chain 7. Under the protection of the cover plate 10 on the guide way 4, the return scraper 5 and the leaf chain 7 are protected, and then the scraper 5 and the leaf chain 7 are continuously transported.
