Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mining conveyors, and in particular to a laser monitoring and alarm device for conveyor belt faults in mining conveyors. Background Technology
[0002] Mining conveyors are key equipment used in mining production for the continuous transport of bulk materials (such as ore, coal, sand and gravel), and are characterized by high efficiency, automation, and long-distance transportation. Mining conveyors are usually composed of belts and drive units. Due to the change in tension at various points after transporting materials, the belts on the conveyor often run off-center, which can lead to belt wear and even equipment damage. Utility Model Content
[0003] To reduce the probability of belt misalignment leading to wear and material spillage, this application provides a laser monitoring and alarm device for belt faults in mining conveyors.
[0004] This application provides a laser monitoring and alarm device for fault detection of conveyor belts in mining applications, which adopts the following technical solution:
[0005] A laser monitoring and alarm device for faulty conveyor belts in mining applications includes a monitoring mechanism and a return mechanism mounted on the belt frame. The monitoring mechanism includes a fixing component mounted on the belt frame. A U-shaped connecting rod is fixedly connected to the fixing component. An infrared transmitter and an infrared receiver are slidably connected to the two ends of the U-shaped connecting rod through an adjusting component, respectively. A PLC controller and an alarm light are also mounted on the U-shaped connecting rod. The PLC controller is communicatively connected to the alarm light and the infrared receiver.
[0006] By adopting the above technical solution, under normal circumstances, the infrared transmitter emits infrared rays, and the infrared receiver receives the emitted infrared rays. When the belt deviates, the deviated belt blocks the infrared rays, thus preventing the infrared receiver from receiving them. At this time, the infrared receiver sends feedback to the PLC controller, and the PLC controller sends a signal to control the alarm light to light up, thereby playing a warning role and making it easier for operators to check in time, reducing the probability of belt deviance causing wear and material spillage.
[0007] Optionally, the fixing component includes a U-shaped fixing block, which is slidably connected to the belt frame and fixedly connected to the U-shaped connecting rod. A first screw hole is provided on the top wall of the U-shaped fixing block, and a first adjusting bolt is threaded into the first screw hole. A clamping block is fixedly connected to one end of the first adjusting bolt near the belt frame.
[0008] By adopting the above technical solution, when installing the entire monitoring mechanism, the U-shaped fixing block is first slidably connected to the belt frame, and then the first adjusting bolt is rotated. The first adjusting bolt drives the clamping block to rotate, and the clamping block abuts against the belt frame, thereby realizing the detachable connection of the monitoring mechanism, so that the monitoring mechanism can be installed at any position on the belt frame.
[0009] Optionally, the adjustment assembly includes two sliding rings, which are slidably connected to both ends of the U-shaped connecting rod and fixedly connected to the infrared transmitter and the infrared receiver, respectively. Limiting racks are fixedly connected to the side walls at both ends of the U-shaped connecting rod. A first sliding groove is formed on the opposite end face of the two sliding rings, and a sliding rod is slidably connected in the first sliding groove. A limiting insert is fixedly connected to the end of the sliding rod near the limiting rack. A spring is fixedly connected to the opposite end face of the two sliding rings, and a connecting ring is fixedly connected to the side wall of the sliding rod. The spring is fixedly connected to the connecting ring.
[0010] By adopting the above technical solution, the sliding ring enables the infrared transmitter and infrared receiver to slide, thereby adjusting the alarm for different degrees of deviation and improving the applicability of the monitoring mechanism; and the limit rack and limit block limit the sliding ring, reducing the probability of accidental sliding of the sliding ring.
[0011] Optionally, the return mechanism includes a mounting base, which is fixedly connected to the belt frame. A mounting component is slidably connected to the mounting base via a sliding assembly, and a rotating roller is rotatably connected to the mounting component.
[0012] By adopting the above technical solution, the setting of the rotating roller realizes the adjustment of the belt that is running off track. When the belt runs off track, the belt that is running off track contacts the rotating roller, the rotating roller rotates and limits the belt, so that it returns to the normal transport track.
[0013] Optionally, the sliding assembly includes a slide rail, which is fixedly connected to the mounting base. A second slider is slidably connected to the slide rail, and a sliding plate is fixedly connected to the second slider. The sliding plate is connected to the mounting assembly, and a third slider is fixedly connected to the sliding plate. A lead screw nut is provided inside the third slider. An adjusting lead screw is also rotatably connected to the mounting base, and the adjusting lead screw cooperates with the lead screw nut.
[0014] By adopting the above technical solution, when adjusting the distance between the rotating roller and the belt, the adjusting screw is manually rotated, which in turn drives the sliding plate to slide through the third slider. The sliding plate drives the rotating roller to slide through the mounting assembly. The sliding of the rotating roller realizes the adjustment of the belt deviation. In addition, the position of the rotating roller can be adjusted according to the maximum allowable belt deviation angle, which improves the applicability of the return mechanism.
[0015] Optionally, the mounting assembly includes a rotating plate rotatably connected to the sliding plate and rotatably connected to the rotating roller. A fixing plate is fixedly connected to the end face of the rotating plate away from the belt. A second sliding groove is formed on the side wall of the fixing plate. A fixing block is fixedly connected to the end face of the sliding plate away from the slide rail. A third sliding groove is formed on the end face of the fixing block away from the sliding plate. A first slider is slidably connected in the third sliding groove. A rotating rod is hinged to one end of the first slider away from the sliding plate. A limit block is rotatably connected to one end of the rotating rod away from the first slider. The limit block is slidably connected in the second sliding groove. A second screw hole is formed on the side wall of the third sliding groove. A second adjusting bolt is threaded into the second screw hole. An abutment block is fixedly connected to one end of the second adjusting bolt located in the third sliding groove. The abutment block abuts against the first slider.
[0016] By adopting the above technical solution, the setting of the rotating plate realizes the adjustment of the rotating roller angle, which in turn facilitates the adjustment of the rotating roller angle according to the inclination angle of the belt, thereby enabling the rotating roller to cooperate with the belt.
[0017] In summary, this application includes the following beneficial technical effects:
[0018] 1. Under normal circumstances, the infrared transmitter emits infrared rays, and the infrared receiver receives the emitted infrared rays. When the belt deviates, the deviated belt blocks the infrared rays, so the infrared receiver cannot receive the infrared rays. At this time, the infrared receiver sends feedback to the PLC controller, and the PLC controller sends a signal to control the alarm light to light up, thus playing a warning role, making it easy for operators to check in time, and reducing the probability of belt deviation causing wear and material spillage.
[0019] 2. The sliding ring design allows the infrared transmitter and receiver to slide, thereby enabling adjustment of alarms for different degrees of deviation and improving the applicability of the monitoring mechanism; furthermore, the limit rack and limit block design limits the sliding ring, reducing the probability of accidental sliding.
[0020] 3. The rotating roller is designed to adjust the belt that is running off track. When the belt runs off track, the belt that is running off track comes into contact with the rotating roller, which rotates and limits the belt, bringing it back to the normal transport track.
[0021] 4. When adjusting the distance between the rotating roller and the belt, manually rotate the adjusting screw, which in turn drives the sliding plate to slide through the third slider. The sliding plate drives the rotating roller to slide through the mounting assembly. The sliding of the rotating roller adjusts the degree of belt deviation. The position of the rotating roller can be adjusted according to the maximum allowable belt deviation angle, which improves the applicability of the return mechanism. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0029] This application discloses a laser monitoring and alarm device for faults in mining conveyor belts.

The monitoring mechanism 3 includes a fixing component 31, which includes a U-shaped fixing block 311. The U-shaped fixing block 311 is slidably connected to the belt frame 1. A first screw hole is provided on the side wall at both ends of the U-shaped fixing block 311. A first adjusting bolt 312 is threaded into the first screw hole. A clamping block 313 is fixedly connected to the end of the first adjusting bolt 312 near the belt frame 1.
[0031] A U-shaped connecting rod 32 is fixedly connected to the side wall of the U-shaped fixing block 311 away from the belt frame 1. Both ends of the U-shaped connecting rod 32 are slidably connected to an infrared transmitter 34 and an infrared receiver 35 respectively through an adjusting component 33. A PLC controller 36 and an alarm light 37 are also fixedly connected to the side wall of the U-shaped connecting rod 32 away from the belt 2. The PLC controller 36 is communicatively connected to the alarm light 37 and to the infrared receiver 35.
[0032] Under normal circumstances, the infrared transmitter 34 emits infrared rays, and the infrared receiver 35 receives the emitted infrared rays. When the belt 2 deviates from its normal position, the deviated belt 2 blocks the infrared rays, thus preventing the infrared receiver 35 from receiving them. At this time, the infrared receiver sends feedback to the PLC controller 36, and the PLC controller 36 sends a signal to control the alarm light 37 to light up, thereby playing a warning role and making it easy for operators to check in time, reducing the probability of wear and spillage caused by belt 2 deviating from its normal position. At the same time, when installing the entire monitoring mechanism 3, the U-shaped fixing block 311 is first slidably connected to the belt frame 1, and then the first adjusting bolt 312 is rotated. The first adjusting bolt 312 drives the clamping block 313 to rotate, and the clamping block abuts against the belt frame 1, thereby realizing the detachable connection of the monitoring mechanism 3, so that the monitoring mechanism 3 can be installed at any position on the belt frame 1.

A sliding rod 335 is slidably connected in the first sliding groove. A limiting insert 333 is fixedly connected to the end of the sliding rod 335 near the limiting rack 332. A fixing sleeve 334 is fixedly connected to the opposite end face of the two sliding rings 331. A spring 337 is fixedly connected to the opposite end face of the two sliding rings 331. The spring 337 is located inside the fixing sleeve 334. A connecting ring 336 is fixedly connected to the side wall of the sliding rod 335. The spring 337 is fixedly connected to the connecting ring 336.
[0034] The sliding ring 331 enables the infrared transmitter 34 and the infrared receiver 35 to slide, thereby adjusting the alarm for different degrees of deviation and improving the applicability of the monitoring mechanism 3. Furthermore, the limiting rack 332 and the limiting block 333 limit the sliding ring 331, reducing the probability of the sliding ring 331 sliding accidentally.
[0035] refer to Figure 4 and Figure 5 The return mechanism 4 includes a mounting base 41, which is fixedly connected to the belt frame 1. A mounting component 44 is slidably connected to the mounting base 41 via a sliding component 43, and a rotating roller 42 is rotatably connected to the mounting component 44.
[0036] The sliding assembly 43 includes two slide rails 431, both of which are fixedly connected to the mounting base 41. A second slider 432 is slidably connected to each of the two slide rails 431. A sliding plate 433 is fixedly connected to both second sliders 432. The sliding plate 433 is connected to the mounting assembly 44.

An adjusting lead screw 435 is also rotatably connected to the mounting base 41. The adjusting lead screw 435 cooperates with the lead screw nut.
[0037] Mounting assembly 44 includes a rotating plate 441, which is rotatably connected to a sliding plate 433 and rotatably connected to a rotating roller 42. A fixing plate 442 is fixedly connected to the end face of the rotating plate 441 away from the belt 2. A second slide groove 45 is formed on the side wall of the fixing plate 442. A fixing block 443 is fixedly connected to the end face of the sliding plate 433 away from the slide rail 431. A third slide groove 46 is formed on the end face of the fixing block 443 away from the sliding plate 433. A first slider 444 is slidably connected in the third slide groove 46. A rotating rod 446 is hinged to one end of the sliding plate 433 away from the first slider 444. A limiting block 445 is rotatably connected to the other end of the rotating rod 446 away from the first slider 444. The limiting block 445 is slidably connected in the second slide groove 45. A second screw hole 47 is provided on the side wall of the third slide groove 46 away from the rotating plate 441. A second adjusting bolt 447 is threaded into the second screw hole 47. An abutment block 448 is fixedly connected to one end of the second adjusting bolt 447 located in the third slide groove 46. The abutment block 448 abuts against the first slider 444.
[0038] The rotating roller 42 is designed to correct the deviation of the belt 2. When the belt 2 deviates, it contacts the rotating roller 42, which rotates and limits the belt 2, bringing it back to the normal transport track. Simultaneously, when adjusting the distance between the rotating roller 42 and the belt 2, the adjusting screw 435 is manually rotated, which in turn drives the sliding plate 433 to slide via the third slider 434. The sliding plate 433 drives the rotating roller 42 to slide via the mounting assembly 44. The sliding of the rotating roller 42 adjusts the degree of belt deviation, allowing the position of the rotating roller 42 to be adjusted according to the maximum allowable belt deviation angle, thus improving the applicability of the corrective mechanism 4. Furthermore, the rotating plate 441 allows for the adjustment of the angle of the rotating roller 42, facilitating the adjustment of the angle of the rotating roller 42 according to the tilt angle of the belt 2, thereby improving the coordination between the rotating roller 42 and the belt 2.
