Description

Technical Field

[0001] This utility model relates to the field of material detection technology for belt conveyors, specifically a material condition detection device for belt conveyors. Background Technology

[0002] As a core material conveying equipment in coal mining, power generation and other fields, coal belt conveyors have the advantages of large conveying capacity, low energy consumption, stable operation and adaptability to complex working conditions. They have become a key carrier in the process of coal flowing from the production end to the consumption end. Therefore, accurate detection of the real-time status of coal materials on coal belt conveyors is a core requirement to ensure the safe operation of equipment, improve conveying efficiency and reduce operation and maintenance costs.

[0003] In existing technologies, material detection for coal conveyor belts generally adopts a manual inspection mode, where operators periodically observe the material conveying status along the conveyor line. This method is not only labor-intensive and inefficient, but also prone to missed or false detections due to visual fatigue and harsh working conditions, failing to meet the real-time and accuracy requirements of modern production. Alternatively, automated detection devices based on fixed detection points can be used. These devices typically fix sensors directly to the conveyor support to monitor the material condition. However, the fixed detection position makes it impossible to flexibly adjust the monitoring range of the detection components according to actual working conditions such as changes in coal conveying volume, adjustments to the width of the conveyor belt, or shifts in material loading areas, resulting in poor detection flexibility. Utility Model Content

[0004] In order to solve the problems in related technologies, this utility model provides a material condition detection device for belt conveyors. This device solves the problem of the inability to adjust the monitoring range of the detection components according to the actual situation of coal transportation and the poor detection flexibility.

[0005] To solve the above problems, the following technical solutions are provided: The present invention relates to a material condition detection device for a belt conveyor, comprising a support frame mounted on a conveyor belt support. The support frame is vertically arranged, and two parallel fixed plates are fixedly connected to the top of the support frame. A horizontally arranged slide rod is slidably connected between the two fixed plates. The slide rod is provided with at least one detection component for detecting the material condition, and an adjustment component for adjusting the position of the detection component is provided between the detection component and the slide rod.

[0006] By adopting the above technical solution, a horizontal sliding rod is set between two parallel fixed plates, and a detection component is configured on the sliding rod. The position of the detection component along the sliding rod is adjusted in conjunction with an adjustment component. This solves the shortcomings of existing fixed detection devices that cannot adapt to actual working conditions such as changes in coal conveying volume, adjustments to the width of the conveyor belt, or migration of material loading areas. This invention allows adjustment of the lateral position of the detection component by sliding the sliding rod, and fine-tuning of the specific position of the detection component on the sliding rod by adjusting the adjustment component. This achieves comprehensive coverage of the material bearing surface of the conveyor belt, improving the comprehensiveness and accuracy of material condition detection, thereby solving the problem of poor flexibility.

[0007] Furthermore, the inner wall of the fixing plate is provided with a first groove extending along the sliding direction of the slide rod, and both ends of the slide rod are provided with a first protrusion that matches the corresponding first groove. The first protrusion is embedded in the first groove and can slide along the length direction of the first groove.

[0008] The above solution uses the first groove and the first protrusion to determine the sliding trajectory of the slide rod, thus avoiding problems such as deviation and jamming during the sliding process.

[0009] Furthermore, the adjustment assembly includes an adjustment block, a connecting rod, and a slider. The adjustment block is located on the side wall of the slider, the upper end of the connecting rod is fixedly connected to the adjustment block, and the lower end of the connecting rod is slidably connected to the slider.

[0010] In the above scheme, by adjusting the settings of the components, when there are minor changes in working conditions such as local accumulation of coal or uneven loading on the conveyor belt, the slider can be slid along the connecting rod to achieve a small range of fine adjustment, ensuring that the detection components are always aligned with the key monitoring points of the material.

[0011] Furthermore, the adjusting block and the slide rod are slidably engaged. A second groove is provided on the side wall of the slide rod, and a second protrusion adapted to the second groove is provided on the slide rod. The second protrusion is embedded in the second groove and can slide along the length direction of the second groove.

[0012] In the above scheme, the setting of the second groove and the second protrusion is used to determine the sliding trajectory of the adjusting block, providing precise guidance for the movement of the adjusting block and avoiding lateral deviation or jamming of the adjusting block during the sliding process.

[0013] Furthermore, the detection component is detachably connected to the end of the sliding block away from the connecting rod.

[0014] By adopting the above technical solution, the detection component and the sliding block are detachable. When the detection component fails, it can be directly disassembled and replaced without disassembling other components such as the adjusting block and connecting rod. This helps to shorten the replacement time, reduce downtime losses in the coal conveying system, and improve production continuity.

[0015] Furthermore, the detection component includes a sensor module, the detection end of which is arranged facing the material bearing surface of the conveyor belt body.

[0016] The above scheme uses sensor modules to monitor the condition of coal materials in real time.

[0017] Furthermore, multiple sliding rods are provided, each of which is horizontally arranged between two fixed plates.

[0018] The above solution expands the layout space of the detection components by setting up multiple sliding rods, increases the detection coverage, and eliminates the problem of blind spots in the wide conveyor belt body.

[0019] Furthermore, a mounting base is fixedly connected to the bottom of the support frame, and the mounting base has a threaded hole. The mounting base is detachably connected to the conveyor belt bracket by bolts passing through the bolt holes.

[0020] The above solution allows for quick installation and disassembly of the support frame and conveyor belt bracket through the installation of the mounting base, thereby reducing costs.

[0021] Furthermore, the support frame is provided with cover plates on its side wall, rear end and top end surfaces, and the cover plates are fixedly connected to the support frame by screws. A door panel is hinged to the front end surface of the support frame, and an observation window is provided on the door panel.

[0022] The above solution uses a cover plate to block coal particles, dust and other impurities that splash during coal conveying. The door panel allows for operation without disassembling the cover plate, making maintenance easier.

[0023] Furthermore, two parallel horizontal plates are fixedly connected to the top of the support frame, and the horizontal plates are arranged perpendicular to the fixed plate.

[0024] In the above scheme, the horizontal plates are arranged perpendicularly to the fixed plates on the top of the support frame to form a rectangular frame structure, which improves the load-bearing capacity and resistance to deformation.

[0025] The above solution has the following advantages: 1. This utility model discloses a material condition detection device for a belt conveyor. By setting a horizontal slide bar between two parallel fixed plates and configuring a detection component on the slide bar, and cooperating with an adjustment component to adjust the position of the detection component along the slide bar, it solves the defects of existing fixed detection devices that cannot adapt to actual working conditions such as changes in coal conveying volume, adjustment of conveyor belt width, or migration of material off-center loading areas. This utility model can adjust the lateral position of the detection component by sliding the slide bar and fine-tune the specific position of the detection component on the slide bar by adjusting the adjustment component, so as to achieve full coverage of the material bearing surface of the conveyor belt body. This is beneficial to improving the comprehensiveness and accuracy of material condition detection, thereby solving the problem of poor flexibility.

[0026] 2. The adjustment component includes an adjustment block, a connecting rod, and a slider. The adjustment block is located on the side wall of the slider. The upper end of the connecting rod is fixedly connected to the adjustment block, and the lower end of the connecting rod is slidably connected to the slider. By setting the adjustment component, when there are minor changes in working conditions such as local accumulation or uneven loading of coal on the conveyor belt body, a small-range fine adjustment can be achieved by sliding the slider along the connecting rod to ensure that the detection component is always aligned with the key monitoring points of the material.

Detailed Implementation

[0028] 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.

[0029] In specific embodiment 1, such as Figures 1-6 As shown, the material condition detection device for a belt conveyor of this utility model includes a support frame 2 mounted on a conveyor belt bracket 1. The support frame 2 is vertically arranged, and two parallel fixed plates 3 are fixedly connected to the top of the support frame 2. A horizontally arranged slide rod 4 is slidably connected between the two fixed plates 3. At least one detection component for detecting material condition is mounted on the slide rod 4. An adjustment component for adjusting the position of the detection component is provided between the detection component and the slide rod 4. By setting the horizontal slide rod 4 between the two parallel fixed plates 3 and configuring the detection component on the slide rod 4, the position of the detection component can be adjusted along the slide rod 4 in conjunction with the adjustment component. This solves the defects of existing fixed detection devices that cannot adapt to actual working conditions such as changes in coal conveying volume, adjustment of the width of the conveyor belt body 17, or migration of material off-center loading areas. This utility model can adjust the lateral position of the detection component by sliding the slide rod 4 and fine-tune the specific position of the detection component on the slide rod 4 by adjusting the adjustment component, so as to achieve full coverage of the material bearing surface of the conveyor belt body 17. This is beneficial to improving the comprehensiveness and accuracy of material condition detection, thereby solving the problem of poor flexibility.

[0030] The inner wall of the fixing plate 3 is provided with a first groove 5 extending along the sliding direction of the slide rod 4. Both ends of the slide rod 4 are provided with a first protrusion that matches the corresponding side of the first groove 5. The first protrusion is embedded in the first groove 5 and can slide along the length direction of the first groove 5. The first groove 5 and the first protrusion are used to determine the sliding trajectory of the slide rod 4 and avoid problems such as deviation and jamming of the slide rod 4 during the sliding process.

[0031] The adjustment assembly includes an adjustment block 6, a connecting rod 7, and a slider 8. The adjustment block 6 is located on the side wall of the slider 4. The upper end of the connecting rod 7 is fixedly connected to the adjustment block 6, and the lower end of the connecting rod 7 is slidably connected to the slider 8. By setting the adjustment assembly, when there are minor changes in working conditions such as local accumulation or uneven loading of coal on the conveyor belt body 17, a small-range fine adjustment can be achieved by sliding the slider 8 along the connecting rod 7 to ensure that the detection assembly is always aligned with the key monitoring points of the material.

[0032] The adjusting block 6 and the slide rod 4 are in a sliding fit. A second groove 9 is provided on the side wall of the slide rod 4, and a second protrusion 10 adapted to the second groove 9 is provided on the slide rod 4. The second protrusion 10 is embedded in the second groove 9 and can slide along the length direction of the second groove 9. The second groove 9 and the second protrusion 10 are used to determine the sliding trajectory of the adjusting block 6, providing precise guidance for the movement of the adjusting block 6 and avoiding lateral deviation or jamming of the adjusting block 6 during the sliding process.

[0033] The detection assembly includes a sensor module 11, with the detection end of the sensor module 11 facing the material bearing surface of the conveyor belt body 17, for real-time monitoring of the coal material condition.

[0034] Multiple slide bars 4 are provided, each slide bar 4 is horizontally arranged between two fixed plates 3. By setting multiple slide bars 4, the arrangement space of the detection components is expanded, the detection coverage range is increased, and the problem of blind spots in the wide conveyor belt body 17 is eliminated.

[0035] The support frame 2 is fixedly connected to the bottom of the mounting base 12. The mounting base 12 has a threaded hole. The mounting base 12 is detachably connected to the conveyor belt bracket 1 by bolts passing through the bolt holes. With the mounting base 12, the support frame 2 and the conveyor belt bracket 1 can be quickly installed and disassembled, thereby reducing costs.

[0036] The top of the support frame 2 is also fixedly connected to two parallel horizontal plates 16. The horizontal plates 16 are arranged perpendicularly to the fixed plate 3 on the top of the support frame 2 to form a rectangular frame structure, which improves the load-bearing capacity and resistance to deformation.

[0037] In specific embodiment 2, the difference between this embodiment and embodiment 1 is that the detection component and the end of the sliding block away from the connecting rod 7 are detachably connected. When the detection component fails, the detection component can be directly disassembled and replaced without disassembling other components such as the adjusting block 6 and the connecting rod 7. This helps to shorten the replacement time, reduce downtime losses of the coal conveying system, and improve production continuity.

[0038] In a specific embodiment 3, such as Figure 1 As shown, the difference between this embodiment and embodiments 1 and 2 is that the support frame 2 in this embodiment is provided with a cover plate 13 on the side wall, rear end face and upper end face. The cover plate 13 is fixedly connected to the support frame 2 by screws. A door panel 14 is hinged on the front end face of the support frame 2. An observation window 15 is opened on the door panel 14. The cover plate 13 is used to block coal particles, dust and other impurities splashed during the coal conveying process. The door panel 14 can be opened directly without disassembling the cover plate 13, which is conducive to improving the convenience of maintenance.

[0039] During operation, the position of the sensor module 11 is precisely adjusted according to the coal conveying conditions. The slide bar 4 is pushed so that the first protrusions at both ends slide along the first groove 5 on the inner wall of the fixed plate 3. The sliding direction of the slide bar 4 is consistent with the conveying direction of the conveyor belt body 17. The adjustment block 6 is pushed so that the second protrusion 10 slides along the second groove 9 on the side wall of the slide bar 4, which drives the connecting rod 7 and the slider 8 to move synchronously. At the same time, the slider 8 can slide along the lower end of the connecting rod 7 to achieve longitudinal fine adjustment of the sensor module 11, ensuring that the detection end of the sensor module 11 is accurately facing the material bearing surface of the conveyor belt body 17.
