Description

Technical Field

[0001] This application belongs to the technical field of coal mine conveyor belt machines, specifically relating to a conveyor belt misalignment detection device for coal mine conveyor belt machines. Background Technology

[0002] In coal mining and material transportation systems, mining belt conveyors (also known as belt conveyors) rely on the principle of friction transmission to become the core equipment for transporting powdery and granular low-abrasive materials such as coal, gravel, and sand. Their operational stability directly affects coal mine production efficiency and operational safety. Due to the complex characteristics of materials in coal mine transportation scenarios and the fact that belts operate under high loads for extended periods, belt misalignment is a common fault. This not only easily leads to material spillage and accelerated belt wear, but in severe cases, it can also cause equipment jamming or even shutdown. Therefore, it is necessary to monitor the belt's operating status in real time through belt misalignment monitoring devices.

[0003] While existing technologies include monitoring devices (such as Chinese patent CN218173666U) that attempt to optimize installation adjustability and monitoring accuracy through methods like screw-fixed clamps and slag-cleaning plates, significant shortcomings remain in practical applications. Firstly, existing devices are ineffective at preventing belt misalignment, relying heavily on single detection components for offset feedback and lacking a structure that actively limits and constrains the belt, making it difficult to reduce misalignment at its source. Secondly, the coordination between limiting and monitoring functions is insufficient; the device cannot flexibly adjust the limiting position according to the belt conveyor's operating conditions, resulting in a monitoring range and limiting accuracy that cannot adapt to the needs of different belt specifications. This reduces the overall effectiveness of the device and fails to meet the operational requirements of efficient and stable transportation in coal mines. Utility Model Content

[0004] Therefore, the technical problem to be solved by this application is to provide a belt misalignment detection device for coal mine conveyor belts, which solves at least one of the technical problems mentioned in the background art.

[0005] To address the aforementioned problems, this application provides a belt misalignment detection device for coal mine conveyor belts, comprising a mounting frame and a belt, wherein the belt is disposed on the top of the mounting frame; and further comprising: A limiting mechanism, comprising a limiting sub-mechanism and at least two misalignment detectors, wherein the misalignment detectors are disposed at the top of the mounting frame and located on both sides of the tape, for real-time monitoring of the misalignment status of the tape and issuing an alarm. The limiting sub-mechanism is located at the top of the mounting frame and on both sides of the tape, and is used to limit the tape.

[0006] Optionally, the limiting sub-mechanism further includes a horizontal adjustment component and a limiting component. The horizontal adjustment component is respectively provided on both sides of the top of the mounting frame, and the limiting component is provided on the horizontal adjustment component for laterally limiting the tape from both sides.

[0007] Optionally, the limiting component includes a limiting plate, a fixing plate, and rollers. The limiting plate is provided on the fixed plate at one end facing the tape, and at least two rollers are provided on the limiting plate at one end facing the tape surface. The side of the fixing plate away from the limiting plate is mounted on the horizontal adjustment component.

[0008] Optionally, the leveling assembly includes a mounting plate, a lead screw, and a guide. The mounting plate is disposed on the top of the mounting frame so that the leveling assembly is disposed on the mounting frame. The lead screw is rotatably mounted on the mounting plate, one end of the lead screw passing through the mounting plate and threadedly connected to the fixed plate. A guide is disposed between the mounting plate and the lead screw. Rotating the lead screw causes the fixed plate to move in the horizontal direction to adjust the distance between the fixed plate and the tape.

[0009] Optionally, the guide is a telescopic rod, and the telescopic rod is connected to both sides of the mounting plate. One end of the telescopic rod is fixedly connected to the fixing plate to provide limiting support for the fixing plate.

[0010] Optionally, the limiting sub-mechanism further includes a first limiting ring, which is fixedly disposed at the top of the mounting bracket and located on both sides of the end of the tape, for limiting the end of the tape.

[0011] Optionally, the deviation monitoring device further includes a vertical adjustment component. The vertical adjustment component is provided in the circulation cavity of the tape and is mounted on the mounting frame for adjusting the tension of the tape.

[0012] Optionally, the vertical adjustment assembly includes a rotating rod and anti-slip wheels. The two ends of the rotating rod are disposed on the mounting frame and can move vertically relative to the mounting frame. A plurality of anti-slip wheels are sleeved on the rotating rod, and the anti-slip wheels are used to support the tape.

[0013] Optionally, the vertical adjustment assembly further includes a threaded rod and a slide groove. The mounting bracket has a slide groove arranged vertically on opposite sides at its ends. A slider is slidably installed in the slide groove. A rotating rod is provided between two oppositely arranged sliders. The threaded rod passes through one of the sliders and is threadedly connected to the slider. Both ends of the threaded rod are rotatably mounted on the slide groove wall. Rotating the threaded rod causes the slider to move up and down along the slide groove, thereby adjusting the vertical position of the anti-slip wheel.

[0014] Optionally, the vertical adjustment assembly further includes a second limiting ring, which is sleeved on both ends of the rotating rod.

[0015] By employing the above technical solution, this utility model application has at least the following beneficial effects: This application provides a belt misalignment monitoring device and a coal mine conveyor belt. A dual anti-misalignment system with detection and constraint functions is constructed through a limiting mechanism. The misalignment detector can monitor the belt's operating status in real time and issue an alarm promptly upon detection of deviation, providing accurate information for subsequent adjustments. Simultaneously, the limiting sub-mechanisms on both sides of the belt form physical constraints, actively limiting and guiding the belt during transportation, significantly reducing misalignment. This solves the problem of existing devices relying solely on single detection and having weak anti-misalignment capabilities, effectively reducing the risk of material spillage, belt wear, and equipment jamming caused by misalignment.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] See also Figures 1 to 4 As shown in the embodiment of this application, a belt misalignment detection device for a coal mine conveyor belt machine is provided, including a mounting frame 1 and a belt 2. The belt 2 is disposed on the top of the mounting frame 1. It also includes a limiting mechanism 3, which includes at least two limiting sub-mechanisms and at least two misalignment detectors 301. The misalignment detectors 301 are disposed on the top of the mounting frame 1 and located on both sides of the belt 2, and are used to monitor the misalignment status of the belt 2 in real time and issue an alarm. The limiting sub-mechanisms are disposed on the top of the mounting frame 1 and located on both sides of the belt 2, and are used to limit the belt 2.

[0023] By constructing a dual anti-deviation system with detection and constraint functions through the limiting mechanism 3, the deviation detector 301 can monitor the running status of the conveyor belt 2 in real time and issue an alarm in time once deviation occurs, providing accurate basis for subsequent adjustments; at the same time, the limiting sub-mechanisms on both sides of the conveyor belt 2 can form physical constraints from both sides of the conveyor belt 2, actively limiting and guiding the conveyor belt 2 during transportation, greatly reducing the occurrence of deviation, solving the problem that the existing device only relies on a single detection and has weak anti-deviation capability, and effectively reducing the risk of material spillage, conveyor belt wear and equipment jamming caused by deviation.

[0024] Among them, the deviation detector 301 is set at the top of the mounting frame 1 and located on both sides of the tape 2; in this embodiment, three deviation detectors 301 are set on one side of the mounting frame 1 along the movement direction of the tape 2; the deviation detector 301 detects the deviation of the tape 2, and when the tape 2 deviates, an alarm can be issued in time, so that the position of the tape 2 can be adjusted in time.

[0025] Specifically, in this embodiment, the misalignment detector 301 is a vertical roller misalignment detector, which is a commercially available part, and the specific model can be selected according to the specific working conditions.

[0026] The limiting sub-mechanism is located at the top of the mounting frame 1 and on both sides of the tape 2. In this embodiment, a limiting sub-mechanism is provided between two adjacent deviation detectors 301. The limiting sub-mechanism limits the tape 2 on both sides of the width direction of the tape 2 to prevent the tape 2 from deviating.

[0027] Multiple misalignment detectors 301 are arranged at the top of the mounting frame 1, which can monitor the misalignment of the tape 2 in real time from different sections of the tape 2. At the same time, the tape 2 is constrained from both sides by multiple limiting sub-mechanisms to avoid misalignment problems caused by lack of local limiting.

[0028] In another embodiment, the limiting sub-mechanism further includes a horizontal adjustment component and a limiting component. The horizontal adjustment component is provided on both sides of the top of the mounting frame 1, and the limiting component is provided on the horizontal adjustment component for laterally limiting the tape 2 from both sides.

[0029] The horizontal adjustment component is used to provide driving force to the limiting component, so that the limiting component can move toward or away from the tape 2 to achieve lateral limiting of the tape 2.

[0030] In another embodiment, the limiting component includes a limiting plate 304, a fixing plate 303 and rollers 305. The fixing plate 303 is provided with the limiting plate 304 at one end facing the tape 2, and the limiting plate 304 is provided with at least two rollers 305 at one end facing the surface of the tape 2. The side of the fixing plate 303 away from the limiting plate 304 is mounted on the horizontal adjustment component.

[0031] The fixed plate 303 has a limiting plate 304 at the end facing the conveyor belt 2. The limiting plate 304 is located in the upper part of the fixed plate 303 so that the lower surface of the limiting plate 304 is higher than the upper surface of the upper belt of the conveyor belt 2. At least two rollers 305 are provided at the end of the limiting plate 304 facing the surface of the conveyor belt 2. The limiting plate 304 and the rollers 305 correspond to the lateral sides of the conveyor belt 2 (i.e., the left and right edges of the conveyor belt 2), which can form a rigid physical barrier from both sides of the conveyor belt 2, directly limiting the lateral movement boundary of the conveyor belt 2, thereby reducing the phenomenon of the conveyor belt 2 running off track. When the conveyor belt 2 tends to run off track to one side due to material offset, uneven tension, etc., its edge will contact the fixed plate 303 on the corresponding side. The fixed plate 303 will prevent the conveyor belt 2 from continuing to move outward, and constrain the conveyor belt 2 within the preset running track to prevent it from deviating from the normal conveying path.

[0032] In another embodiment, the horizontal adjustment assembly includes a mounting plate 302 and a lead screw 306. The mounting plate 302 is disposed on the top of the mounting frame 1 so that the horizontal adjustment assembly is disposed on the mounting frame 1. The lead screw 306 is rotatably mounted on the mounting plate 302. One end of the lead screw 306 passes through the mounting plate 302 and is threadedly connected to the fixing plate 303. A guide is provided between the mounting plate 302 and the lead screw 306. Rotating the lead screw 306 causes the fixing plate 303 to move in the horizontal direction to adjust the distance between the fixing plate 303 and the tape 2.

[0033] The mounting plate 302 is disposed on the top of the mounting frame 1 so that the horizontal adjustment component is installed on the top of the mounting frame 1. The mounting plate 302 is used to realize the installation of the horizontal adjustment component on the mounting frame 1 on the one hand, and to support the limiting component on the other hand.

[0034] Specifically, both the mounting plate 302 and the fixing plate 303 are rectangular plates, arranged parallel to each other along the moving direction of the limiting plate 304, and there is a gap between them to provide moving space for the fixing plate 303 and the limiting plate 304.

[0035] A lead screw 306 is rotatably mounted on the mounting plate 302. One end of the lead screw 306 passes through the mounting plate 302 and is threadedly connected to the fixing plate 303. The mounting plate 302 and the lead screw 306 are rotatably mounted so that there is only rotational freedom and no translational freedom between the lead screw 306 and the mounting plate 302. At least part of the end of the lead screw 306 extends out of the end face of the mounting plate 302 away from the fixing plate 303, and a cap is provided at the end. One end of the lead screw 306 passes through the mounting plate 302 and is threadedly connected to the fixing plate 303. A guide is provided between the mounting plate 302 and the lead screw 306. The guide is provided so that when the lead screw 306 rotates and drives the fixing plate 303 to move horizontally, the fixing plate 303 will not rotate.

[0036] Specifically, the guide component is a telescopic rod 307. Both sides of the mounting plate 302 are connected to the telescopic rod 307. One end of the telescopic rod 307 is fixedly connected to the fixing plate 303 to provide limiting support for the fixing plate 303.

[0037] Telescopic rods 307 are connected to both sides of the mounting plate 302. In this embodiment, the telescopic rods 307 are symmetrically arranged on the mounting plate 302 with the lead screw 306 as the center of symmetry. They are also connected to the end face of the fixing plate 303 away from the mounting limit plate 304 to limit the rotational freedom of the fixing plate 303.

[0038] More specifically, in other embodiments, the guide may also be a slide block assembly or a guide rail block assembly.

[0039] In another embodiment, the limiting sub-mechanism further includes a first limiting ring 308, which is fixedly disposed at the top of the mounting frame 1. The first limiting ring 308 is located on both sides of the end of the tape 2 and is used to limit the end of the tape 2. The tape 2 has two first limiting rings 308 mounted on the mounting frame 1 on both ends. The two oppositely arranged first limiting rings 308 can laterally limit the tape 2, preventing the tape 2 from deviating at the end.

[0040] In another embodiment, the deviation monitoring device further includes a vertical adjustment component 4. One end of the circulation cavity of the tape 2 is provided with the vertical adjustment component 4, which is mounted on the mounting frame 1 and is used to adjust the tightness of the tape 2.

[0041] The inner circulation cavity of the tape 2 is the space enclosed by the upper and lower belt sections of the tape. A vertical adjustment component 4 is installed at one end of the inner circulation cavity of the tape 2. The vertical adjustment component 4 is typically arranged laterally along the tape 2, and its two ends are mounted on the side walls of the mounting frame 1. The vertical adjustment component 4 has a vertical degree of freedom of movement, and tensions the tape 2 through vertical movement.

[0042] In another embodiment, the vertical adjustment assembly 4 includes a rotating rod 401 and anti-slip wheels 402. The two ends of the rotating rod 401 are disposed on the mounting frame 1 and move vertically relative to the mounting frame 1. A plurality of anti-slip wheels 402 are sleeved on the rotating rod 401 and the anti-slip wheels 402 are used to support the tape 2.

[0043] The rotating rod 401 has two ends mounted on the mounting frame 1 and moves vertically relative to the mounting frame 1. The rotating rod 401 is usually arranged in the transverse direction of the tape 2, covering the entire transverse direction of the tape 2. Multiple anti-slip wheels 402 are sleeved on the rotating rod 401. The arrangement of multiple anti-slip wheels 402 increases the contact area with the inner wall of the tape 2, thereby improving the overall friction and preventing the tape 2 from slipping during operation.

[0044] In another embodiment, the vertical adjustment assembly 4 further includes a threaded rod 406 and a slide groove 405. The mounting bracket 1 has a slide groove 405 arranged vertically on opposite sides at its end. A slider 404 is slidably installed in the slide groove 405. A rotating rod 401 is provided between two sliders 404 arranged opposite to each other. The threaded rod 406 passes through one of the sliders 404 and is threadedly connected to the slider 404. Both ends of the threaded rod 406 are rotatably installed on the groove wall of the slide groove 405. Rotating the threaded rod 406 causes the slider 404 to move up and down along the slide groove 405, thereby adjusting the vertical position of the anti-slip wheel 402.

[0045] The mounting bracket 1 has vertically arranged grooves 405 on opposite sides at its ends. A slider 404 is slidably mounted within each groove 405. The grooves 405 can be fixed to the mounting bracket 1 by bolts, or they can be formed on the side wall of the mounting bracket 1. The slider 404 can move along the grooves 405. A rotating rod 401 is provided between the two opposing sliders 404, allowing the rod to rotate relative to the sliders 404. A threaded rod 406 passes through one of the sliders 404 and is threadedly connected to the slider 404. Both ends of the threaded rod 406 are rotatably mounted on the groove wall of the slide 405. The slide 405 can be used to restrict the movement trajectory of the slider 404 and also as a carrier for mounting the threaded rod 406. The threaded rod 406 is arranged vertically and is rotatably mounted on the groove wall of the slide 405. That is, the threaded rod 406 only has rotational freedom relative to the slide 405. The threaded rod 406 is threadedly connected to the slider 404. Under the restriction of the slide 405, the slider 404 can only move vertically up and down under the rotation of the threaded rod 406, which in turn drives the rotating rod 401 and the anti-slip wheel 402 to move vertically up and down, thus tensioning the tape 2.

[0046] In another embodiment, the vertical adjustment component 4 further includes a second limiting ring 403, which is sleeved on both ends of the rotating rod 401.

[0047] The second limiting ring 403 is fixed at both ends of the rotating rod 401 and symmetrically distributed on both sides of the conveyor belt 2. It directly limits the lateral movement range of the conveyor belt 2 through physical obstruction. When the conveyor belt 2 tends to deviate to one side due to uneven tension, material offset, etc., its edge will contact the second limiting ring 403 on the corresponding side. The second limiting ring 403 forms a rigid constraint based on the fixed structure of the rotating rod 401, preventing the conveyor belt 2 from continuing to deviate along the axial direction of the rotating rod 401, and limiting the conveyor belt 2 within the preset conveying width range, preventing it from deviating from the support range of the rotating rod 401.

[0048] The limiting submechanism is equipped with a lead screw 306 and a telescopic rod 307 adjustment structure. Rotating the lead screw 306 can drive the fixed plate 303 to move laterally, flexibly adjusting the distance between the limiting plate 304 and the tape 2 to adapt to tapes 2 of different widths. The telescopic rod 307 provides stable support for the fixed plate 303, ensuring that the limiting position can still maintain a reliable constraint effect after adjustment. In addition, the threaded rod 406 in the vertical adjustment component 4 drives the slider 404 and the second limiting ring 403 to move up and down, flexibly adjusting the position of the rotating rod 401 and the anti-slip wheel 402, thereby adapting to different tightness conditions of the tape 2, realizing dynamic adaptation of the limiting and monitoring functions, and solving the problem that existing devices are difficult to adjust according to working conditions and have poor adaptability.

[0049] The overall structure is simple in design, and the assembly and operation process is easy. It can be put into coal mine operation scenarios without complicated debugging, reducing the difficulty of operation for workers. The components are highly coordinated. The real-time monitoring of the vertical roller type deviation detector and the active constraint of the limit structure form a closed loop, which not only ensures the accuracy of monitoring, but also enhances the effectiveness of preventing deviation. At the same time, the stable support of components such as the telescopic rod 307 and the limit ring improves the durability of the device in high-load transportation environment, extends the service life of the equipment, and comprehensively optimizes the use effect of the device to meet the operation requirements of efficient and stable transportation of coal mine belt conveyors.

The above are merely preferred embodiments of this application.
