Description

Technical Field

[0001] This invention relates to the field of underground coal transportation technology, and in particular to a split-type sprocket shaft assembly for a scraper conveyor. Background Technology

[0002] The main function of a scraper conveyor in a fully mechanized coal mining face is to continuously transport the coal mined by the coal mining machine to the transfer conveyor, ensuring the continuous transport of coal out of the mine. The sprocket shaft assembly, as the power output component of the scraper conveyor, is a key component. During operation, it withstands severe impacts from the scraper chain, coal blocks, and rocks. The harsh working conditions require it to possess high strength and toughness, while also demanding high wear resistance and a long service life for the sprockets.

[0003] The inventors of this application have discovered the following problems in practical use: In existing related technologies, the main structural form of sprocket shaft assemblies is generally an integral structure. However, when using an integral sprocket shaft assembly, the sprocket ring is a vulnerable part. After a period of use, it needs to be reversed or replaced. When replacing the sprocket ring of an integral sprocket shaft assembly, the entire sprocket shaft assembly needs to be removed from the frame. Due to its large size and heavy weight, disassembly is relatively difficult.

[0004] Therefore, the present invention provides a split sprocket shaft assembly for scraper conveyors to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a split-type sprocket shaft assembly for scraper conveyors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A split-type sprocket shaft assembly for a scraper conveyor includes an annular column as a connecting carrier. The surface of the annular column is provided with a movable mechanism, and the surface of the annular column is provided with a disassembly mechanism. A reversing mechanism is fixedly connected to the surface of the disassembly mechanism.

[0008] The movable mechanism includes an arc-shaped block fixed to the surface of an annular column, and a connecting ring on the surface of the arc-shaped block. An arc-shaped groove is formed on the inner surface of the connecting ring, and multiple sets of threaded holes are formed on the surface of the connecting ring. A locking block is fixedly connected to the surface of the connecting ring, and a rotating ring is formed on the surface of the locking block. A locking groove is formed on the inner surface of the rotating ring. A limiting bolt is movably connected to the surface of the rotating ring, and a prism is fixedly connected to the surface of the rotating ring. A threaded hole is formed on the surface of the prism, and gear teeth are movably connected to the surface of the prism. A limiting bolt is provided inside the threaded hole. When the gear teeth need to be replaced, by turning the limiting bolt and simultaneously sliding the gear teeth, the gear teeth can be separated from the prism, facilitating the replacement of damaged gear teeth without disassembling the entire sprocket shaft assembly, resulting in good performance.

[0009] As a further embodiment of the present invention, the gear teeth form a movable structure through the through holes and the second limiting bolt. Multiple sets of prisms are provided, and the prisms and the rotating ring are an integrated structure. Since multiple sets of prisms and the second threaded holes are provided on the surface of the rotating ring, the gear teeth can engage with the prisms. By turning the second limiting bolt, the gear teeth can be limited, and the number of gear teeth can be adjusted according to the usage requirements.

[0010] As a further embodiment of the present invention, the inner wall of the slot is in contact with the surface of the card block, and the inner wall of the rotating ring is in contact with the surface of the connecting ring. By turning the limiting bolt one and simultaneously sliding the rotating ring, the rotating ring can be slid to a suitable position, and then the limiting bolt one can be turned to limit it, thereby adjusting the spacing between the rotating rings, which is practical.

[0011] As a further embodiment of the present invention, the surface of the arc-shaped block is in contact with the inner wall of the arc-shaped groove, and the inner wall of the connecting ring is in contact with the surface of the annular column. Since the arc-shaped block and the arc-shaped groove are engaged, the connecting ring can be limited. At the same time, by sliding the connecting ring, the connecting ring and the annular column can be separated.

[0012] As a further embodiment of the present invention, the limiting bolt is connected to the threaded hole by a thread, and the rotating ring is connected to the limiting bolt by a through hole to form a movable structure. By using the threaded hole and the limiting bolt together, the indirection between the rotating rings can be adjusted according to actual usage requirements.

[0013] As a further embodiment of the present invention, the disassembly mechanism includes a connecting plate fixed to the inner wall of the annular column, and a threaded post is fixedly connected to the surface of the connecting plate. A concave ring is movably connected to the surface of the threaded post, and a limit nut is threadedly connected to the surface of the threaded post. A groove is formed on the inner surface of the concave ring, and the inner wall of the groove fits against the outer surface of the annular column. When the connecting ring needs to be disassembled, the concave ring can be separated from the connecting ring by turning the limit nut and sliding the concave ring. At the same time, since the arc-shaped block and the connecting ring are engaged with each other, the connecting ring can be separated from the annular column by sliding the connecting ring, making disassembly convenient.

[0014] As a further embodiment of the present invention, a threaded post II is fixedly connected to the surface of the concave ring, and a limit nut II is threadedly connected to the surface of the threaded post II. A limit ring is movably connected to the surface of the threaded post II, and a trapezoidal block is fixedly connected to the surface of the limit ring. Several sets of balls are provided on the inner surface of the limit ring, and the surface of the balls is in contact with the surface of the connecting ring. When the whole assembly needs to be disassembled, the concave ring can be separated from the annular post by turning the limit nut II and sliding the concave ring. The present invention can be disassembled into individual parts, which is convenient for carrying and transportation, and avoids the problem of the integral sprocket shaft assembly being too large and inconvenient to transport.

[0015] As a further embodiment of the present invention, the reversing mechanism includes a connecting column fixed to the surface of the limiting ring, and a limiting block is fixedly connected to the surface of the connecting column. A transmission gear is provided on the surface of the connecting column, and a limiting groove is formed on the inner surface of the transmission gear. A threaded column three is fixedly connected to the surface of the connecting column, and a limiting nut three is connected to the surface of the threaded column three through a thread. By turning the limiting nut three and sliding the transmission gear, the transmission gear can be separated from the threaded column three and the connecting column, which facilitates the disassembly and replacement of the transmission gear.

[0016] As a further embodiment of the present invention, the inner wall of the limiting groove is in contact with the surface of the limiting block, and the surface of the limiting nut three is in contact with the surface of the transmission gear. When it is necessary to change direction, the disassembled transmission gear is engaged with the threaded post three and the connecting post on the other side, and the limiting nut three is turned to limit the direction, so that the sprocket shaft assembly can be changed.

[0017] Compared with related technologies, the split-type sprocket shaft assembly for scraper conveyors provided by the present invention has the following beneficial effects:

[0018] 1. In use, this invention solves the problem that sprocket rings are easily damaged parts and need to be reversed or replaced after a period of use. When replacing sprocket rings in an integral sprocket shaft assembly, the entire assembly needs to be removed from the frame, which is difficult due to its large size and weight. This invention, by turning the limit bolt two and simultaneously sliding the gear teeth, separates the gear teeth from the prisms, facilitating gear replacement without disassembling the entire sprocket shaft assembly. Furthermore, the rotating ring surface has multiple sets of prisms and threaded holes, which, in conjunction with the gear teeth, allow for timely adjustment of the number of teeth, resulting in better performance. By turning the limit bolt one and simultaneously sliding the rotating ring, the threaded holes on the connecting ring surface allow for adjustment of the spacing between the rotating rings, further improving performance.

[0019] 2. When using this invention, by tightening the second limiting nut and sliding the concave ring, the concave ring can be separated from the connecting ring. At the same time, since the arc-shaped block and the connecting ring are engaged with each other, sliding the connecting ring can separate the connecting ring from the annular column. Disassembly is convenient. By tightening the second limiting nut and sliding the concave ring, the concave ring can be separated from the annular column. This invention can be disassembled into individual parts, which is convenient for carrying and transportation, avoiding the problem of the integral sprocket shaft assembly being too large and inconvenient to transport.

[0020] 3. When using this invention, by turning the limit nut three and sliding the transmission gear, the transmission gear can be separated from the threaded column three and the connecting column, which is convenient for disassembling and replacing the transmission gear. At the same time, when it is necessary to change direction, the transmission gear can be engaged with the threaded column three and the connecting column on the other side.

[0021] In summary, this invention allows for easy replacement of the gear teeth by turning the second limiting bolt and simultaneously sliding the gear teeth, thus facilitating the removal of the entire sprocket shaft assembly without disassembling the entire assembly. Furthermore, by turning the second limiting nut and sliding the concave ring, the concave ring can be separated from the annular column, allowing the invention to be disassembled into individual components for easy transport and avoids the inconvenience of transporting an integral sprocket shaft assembly.

A threaded hole 210 is provided on the surface of the prism 209, and a gear tooth 211 is movably connected to the surface of the prism 209. A limit bolt 212 is provided inside the threaded hole 210. When the gear tooth 211 needs to be replaced, the gear tooth 211 can be separated from the prism 209 by turning the limit bolt 212 and sliding the gear tooth 211 at the same time. This makes it convenient to replace the damaged gear tooth 211 without disassembling the entire sprocket shaft assembly, resulting in good performance.

[0032] Reference Figure 1-6The gear teeth 211 shown form a movable structure through the through hole and the second limiting bolt 212. Multiple sets of prisms 209 are provided, and the prisms 209 and the rotating ring 206 are an integrated structure. Since multiple sets of prisms 209 and threaded holes 210 are provided on the surface of the rotating ring 206, the gear teeth 211 can engage with the prisms 209. By turning the second limiting bolt 212, the gear teeth 211 can be limited. The number of gear teeth 211 can be adjusted according to the usage requirements.

[0033] Reference Figure 1-6 The inner wall of the slot 207 is in contact with the surface of the block 205, and the inner wall of the rotating ring 206 is in contact with the surface of the connecting ring 202. By turning the limiting bolt 208 and simultaneously sliding the rotating ring 206, the rotating ring 206 can be slid to a suitable position, and then the limiting bolt 208 can be turned to limit it. This allows for adjustment of the spacing between the rotating rings 206, making it highly practical.

Since the arc-shaped block 201 and the arc-shaped groove 203 are engaged, the connecting ring 202 can be limited. At the same time, by sliding the connecting ring 202, the connecting ring 202 can be separated from the annular column 1.

[0035] Reference Figure 1-6 The limit bolt 208 shown is connected to the threaded hole 204 via a thread. The rotating ring 206 forms a movable structure with the limit bolt 208 via a through hole. By using the threaded hole 204 and the limit bolt 208 together, the indirection between the rotating rings 206 can be adjusted according to actual usage requirements. Example 2:

A concave ring 303 is movably connected to the surface of the threaded column 302, and a limit nut 304 is threadedly connected to the surface of the threaded column 302. A groove 305 is provided on the inner surface of the concave ring 303, and the inner wall of the groove 305 fits against the outer surface of the annular column 1. When it is necessary to disassemble the connecting ring 202, the concave ring 303 can be separated from the connecting ring 202 by turning the limit nut 308 and sliding the concave ring 303. At the same time, since the arc block 201 and the connecting ring 202 are engaged with each other, the connecting ring 202 can be separated from the annular column 1 by sliding the connecting ring 202, which is convenient for disassembly.

[0037] In this embodiment, refer to Figure 1-6As shown, a threaded post 306 is fixedly connected to the surface of the concave ring 303, and a limit nut 308 is threadedly connected to the surface of the threaded post 306. A limit ring 309 is movably connected to the surface of the threaded post 306, and a trapezoidal block 310 is fixedly connected to the surface of the limit ring 309. Several sets of balls 307 are provided on the inner surface of the limit ring 309. The surface of the balls 307 is in contact with the surface of the connecting ring 202. When the whole assembly needs to be disassembled, the concave ring 303 can be separated from the annular post 1 by turning the limit nut 308 and sliding the concave ring 303. The invention can be disassembled into individual parts, which is convenient for carrying and transportation, and avoids the problem of the integral sprocket shaft assembly being too large and inconvenient to transport.

A transmission gear 403 is provided on the surface of the connecting post 401, and a limiting groove 404 is opened on the inner surface of the transmission gear 403. A threaded post 405 is fixedly connected to the surface of the connecting post 401, and a limiting nut 406 is threadedly connected to the surface of the threaded post 405. By turning the limiting nut 406, the transmission gear 403 can be slid, and the transmission gear 403 can be separated from the threaded post 405 and the connecting post 401, which facilitates the disassembly and replacement of the transmission gear 403.

[0040] The working principle of this invention is as follows: When it is necessary to replace the gear tooth 211, by tightening the second limiting bolt 212 and simultaneously sliding the gear tooth 211, the gear tooth 211 can be separated from the prism 209, making it convenient to replace the damaged gear tooth 211 without disassembling the entire sprocket shaft assembly, resulting in good performance. Since multiple sets of prisms 209 and threaded holes 210 are provided on the surface of the rotating ring 206, the gear tooth 211 can engage with the prism 209. By tightening the second limiting bolt 212, the gear tooth 211 can be limited, and the number of gear teeth 211 can be adjusted according to usage requirements, resulting in better performance. By tightening the first limiting bolt 208 and simultaneously sliding the rotating ring 206, the rotating ring 206 can be slid to a suitable position, and then the first limiting bolt 208 can be tightened to limit it, thus adjusting the spacing between the rotating rings 206, providing good practicality. When it is necessary to disassemble the connecting ring 202, by tightening the second limiting nut 308... By sliding the concave ring 303, the concave ring 303 can be separated from the connecting ring 202. At the same time, since the arc-shaped block 201 and the connecting ring 202 are engaged with each other, sliding the connecting ring 202 can separate the connecting ring 202 from the annular column 1, making disassembly convenient. When the whole assembly needs to be disassembled, by turning the limit nut 2 308 and sliding the concave ring 303, the concave ring 303 can be separated from the annular column 1. The invention can be disassembled into individual parts, which is convenient for carrying and transportation, avoiding the bulky and inconvenient transportation of the integral sprocket shaft assembly. When the direction needs to be reversed, by turning the limit nut 3 406 and sliding the transmission gear 403, the transmission gear 403 can be separated from the threaded column 3 405 and the connecting column 401, making it convenient to disassemble and replace the transmission gear 403. At the same time, the transmission gear 403 is engaged with the threaded column 3 405 and the connecting column 401 on the other side, and the limit nut 3 406 is turned to limit it, so that the sprocket shaft assembly can be reversed.
