Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to an automatic correction device for a foldable mining conveyor. Background Technology

[0002] As continuous transportation equipment, belt conveyors play a vital role in mining industries such as coal mines and metal mines, serving as a key link in ensuring efficient material transportation. However, the underground working environment is typically characterized by narrow spaces, varied roadways, and frequent changes in the working face, which places stringent requirements on the structural adaptability of conveyors.

[0003] Traditional mining conveyors are mostly integral or segmented rigid structures, with large lengths and volumes. They are cumbersome to transport, install, and turn underground, consuming significant manpower and resources and severely impacting the overall efficiency and flexibility of mining operations. To adapt to changes in the working face, the conveyors need to be frequently disassembled and reassembled, a tedious and time-consuming process.

[0004] During prolonged high-load operation, conveyor belts are prone to misalignment due to uneven stress, roller wear, or uneven material loading. Misalignment not only causes material spillage and increases cleaning workload, but also severely damages the belt edges and frame, reducing equipment lifespan and, in severe cases, leading to belt tearing and other serious accidents, posing a significant threat to safe production. Currently, misalignment is addressed through two main methods: manual inspection and adjustment, which are slow to respond and inconsistent in effectiveness; and external automatic correction devices, which are typically added as accessories, resulting in low integration with the conveyor body, complex structures, and the occupation of valuable underground space. Furthermore, the efficiency and reliability of their coordinated operation are difficult to guarantee.

[0005] Therefore, this utility model proposes a foldable automatic correction device for mining conveyors to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a foldable automatic correction device for mining conveyors, which aims to improve the existing technology of mining conveyors, which suffer from structural rigidity, inconvenience in transportation and transfer, and lack of an integrated and efficient automatic correction structure for conveyor belt deviation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a foldable mining conveyor automatic correction device, comprising a first support plate, a conveyor belt, a folding assembly, a limiting assembly, and support legs.

[0008] The folding assembly includes a second support plate fixed to a first support plate, and a first rotating plate rotatably connected to the second support plate.

[0009] The limiting assembly is disposed on the first support plate and includes a second rotating plate rotatably connected to the first support plate via a second rotating shaft, and a hydraulic cylinder for driving the second rotating plate to rotate.

[0010] The conveyor belt is supported on the first support plate, and the outriggers are connected to the bottom of the first support plate. Through the integrated structure of the folding component and the limiting component, the device can be conveniently folded and efficiently automatically corrected.

[0011] Preferably, the folding assembly further includes a rotating column rotatably disposed within the second support plate, the rotating column being linked to the first rotating plate; the folding assembly also includes a locking mechanism for selectively locking the rotating column to restrict its rotation.

[0012] Preferably, the locking mechanism includes a limiting post that can be separably engaged with the rotating post, and a sliding post that is linked to the limiting post and used to drive the movement of the limiting post.

[0013] Preferably, the locking mechanism further includes a pull plate connected to the sliding column; a first fixing plate fixedly connected to the sliding column, with a limiting post disposed on the first fixing plate; and a spring sleeved on the sliding column.

[0014] Preferably, the limiting assembly further includes a transmission mechanism connected between the output end of the hydraulic cylinder and the second rotating plate.

[0015] Preferably, the transmission mechanism includes a second fixed plate connected to the output end of the hydraulic cylinder, and a connecting rod with one end rotatably connected to the second fixed plate and the other end rotatably connected to the second rotating plate.

[0016] Preferably, the limiting component further includes a slide rail fixed on the first support plate and a limiting plate fixed on the second fixed plate and slidingly engaging with the slide rail.

[0017] Preferably, the transmission mechanism further includes a connecting frame, which is fixedly connected to the output end of the hydraulic cylinder, and a second fixing plate is disposed inside the connecting frame.

[0018] Preferably, the limiting component further includes a connecting plate fixed to the first support plate, and the hydraulic cylinder is pivotally connected to the connecting plate via a first rotating shaft.

[0019] This utility model has the following beneficial effects: 1. In this utility model, by setting a folding component with a locking mechanism, reliable folding and unfolding connection between the support plates of each section of the conveyor is realized, which solves the problem that the existing mining conveyor has a strong overall structure and a large volume, making it difficult to transport, transfer and quickly deploy in narrow underground spaces. It achieves the technical effect of compact structure, easy transportation, flexible deployment and stable connection.

[0020] 2. In this utility model, by integrating a limiting component driven by a hydraulic cylinder into the conveyor support plate, the problem of existing conveyor belt deviation relying on manual adjustment and slow response, or the complex structure and low integration of external correction devices, is solved, achieving the technical effect of high degree of automation, rapid response and stable operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-5This utility model provides an embodiment of a foldable automatic correction device for mining conveyors, which aims to solve the problems of existing mining conveyors having a simple structure, being inconvenient to transport and transfer, and lacking an efficient automatic correction structure integrated with the machine body to address the problem of conveyor belt deviation.

[0025] The foldable mining conveyor automatic correction device includes a first support plate 2, a conveyor belt 1 supported on the first support plate 2, a folding component 3 and a limiting component 4 integrated on the first support plate 2, and a support leg 5 connected to the bottom of the first support plate 2. Specifically, the folding assembly 3 is used to realize the folding connection between this device and another adjacent device. It includes a second support plate 302 fixed to the first support plate 2 and a first rotating plate 301 rotatably connected to the second support plate 302. The rotation of the first rotating plate 301 relative to the second support plate 302 provides a structural basis for the overall folding of the device. The limiting component 4 is used to actively correct the conveyor belt 1 when it deviates from its designated path. It is mounted on the first support plate 2 and includes a second rotating plate 409 as the correction actuator. The second rotating plate 409 is rotatably connected to the top of the first support plate 2 via a second rotating shaft 410. The limiting component 4 also includes a hydraulic cylinder 403 as a power source. The hydraulic cylinder 403 is used to output power to drive the second rotating plate 409 to rotate, thereby realizing the correction action of the conveyor belt 1.

[0026] The bottom of the second support plate 302 is fixed to the bottom of the first support plate 2. The first rotating plate 301 is rotatably connected to the side wall of the second support plate 302. The rotating column 303 is rotatably connected to the inner wall of the second support plate 302. The rotating column 303 is also connected to the first rotating plate 301 in a transmission connection to achieve synchronous rotation. To achieve reliable locking and unlocking of the folding action, the folding assembly 3 also includes a locking mechanism, which includes a sliding post 305 slidably disposed inside the second support plate 302. One end of the sliding post 305 is connected to a pull plate 304 for manual operation, and the other end is fixedly connected to a first fixing plate 306. A limit post 307 is provided on the first fixing plate 306. The limit post 307 is used to engage with the rotating post 303 in a separable manner. A spring 308 is sleeved on the outer wall of the sliding post 305 to provide a restoring force to the sliding post 305. When folding is required, pulling the pull plate 304 can drive the sliding column 305 to slide against the elastic force of the spring 308, thereby driving the first fixed plate 306 and the limiting column 307 to move synchronously, so that the limiting column 307 is disengaged from the locking state of the rotating column 303, thereby releasing the rotation lock on the first rotating plate 301. After folding to the position, releasing the pull plate 304 will push the sliding column 305 to reset in the opposite direction, so that the limiting column 307 re-engages with the rotating column 303, completing the locking.

[0027] The limiting component 4 includes a transmission mechanism connected between the output end of the hydraulic cylinder 403 and the second rotating plate 409. The transmission mechanism includes a connecting frame 404 fixedly connected to the output end of the hydraulic cylinder 403. A second fixed plate 405 is disposed in the connecting frame 404. One end of a connecting rod 408 is rotatably connected to the second fixed plate 405, and the other end of the connecting rod 408 is rotatably connected to the side wall of the second rotating plate 409. The limiting component 4 is also provided with a guide structure, which includes a slide rail 407 fixed on the first support plate 2 and a limiting plate 406 fixed on the top of the second fixed plate 405. The limiting plate 406 and the slide rail 407 are slidably engaged. In order to ensure that the hydraulic cylinder 403 is securely installed and can adapt to angle changes during movement, the limiting assembly 4 also includes a connecting plate 401 fixed on the first support plate 2, and the hydraulic cylinder 403 is pivotally connected to the connecting plate 401 through the first rotating shaft 402.

[0028] Working principle: During the folding operation, the pull plate 304 is pulled first. The pull plate 304 drives the sliding column 305 to slide inside the second support plate 302. During the sliding process, the sliding column 305 compresses the spring 308. At the same time, the first fixed plate 306, which is fixedly connected to the sliding column 305, and the limiting column 307 set on the first fixed plate 306 move synchronously. After the limiting column 307 moves, it disengages from the locking state with the rotating column 303. At this time, the lock is released, and the first support plate 2 can be moved to make the first rotating plate 301 rotate around the second support plate 302, and the rotating column 303 rotates synchronously, thereby realizing the folding between the two adjacent first support plates 2. Through the synergistic effect of the folding component 3 and the locking mechanism, the problems of fixed structure, inconvenient transportation and deployment of the existing conveyor are solved.

[0029] During the operation of the conveyor, when the conveyor belt 1 deviates from its designated path, the limiting component 4 is activated, and the hydraulic cylinder 403 begins to work. Its output end pushes the connecting frame 404 and the internal second fixed plate 405 to move linearly. This movement is guided by the sliding cooperation between the slide rail 407 fixed on the first support plate 2 and the limiting plate 406 fixed on the second fixed plate 405, ensuring the smoothness of the movement. The linear movement of the second fixed plate 405 is converted into the rotational movement of the second rotating plate 409 through the connecting rod 408. The second rotating plate 409 then rotates around its own second rotating axis 410 and uses its side edge to push against the edge of the conveyor belt 1, applying a corrective force to push the deviated conveyor belt 1 back onto the correct track. Through this series of linkages of the limiting component 4, the automated, integrated, and precise correction of the conveyor belt deviation is achieved.
