Description

Technical Field

[0001] This utility model relates to the field of tear detection technology, specifically a novel conveyor belt tear detection device. Background Technology

[0002] Belt conveyors are bulk material transport equipment, typically consisting of rollers, idlers, conveyor belts, drive units, protective devices, and counterweights. They are widely used in ports, power plants, steel mills, and other enterprises. Conveyor belts are primarily made of rubber, making them easily scratched by foreign objects.

[0003] In the prior art, the authorized announcement number CN220866413U discloses a conveyor belt tear detection device, which includes a conveyor belt body, a support mechanism connected to the outside of the conveyor belt body, a detection mechanism set on the outside of the conveyor belt body, and an adjustment mechanism connected to the outer end of the detection mechanism; through the structural design of the detection mechanism, a simple and effective structure and low cost are achieved.

[0004] By installing steel wires under the conveyor belt, when a wire inside a tear in the conveyor belt hits a detection wire, the strong force causes the detection wire to shift, which in turn moves a counterweight. Once the counterweight moves away from a microswitch, it sends a stop signal to the conveyor belt to prevent the tear from widening further. However, when the tear is small, only a small amount of material flows down, and the exposed wires are too short to hit the detection wire, resulting in a failure to detect the tear. Therefore, a novel conveyor belt tear detection device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a novel conveyor belt tear detection device to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel conveyor belt tear detection device, comprising an idler bracket, on which a conveyor belt idler is rotatably mounted, and a conveyor belt body is provided on the conveyor belt idler. A collection mechanism is provided between the idler brackets, and the collection mechanism includes a support column disposed between the idler brackets. A crossbar is fixedly installed between the support columns. A first spring is provided at the upper end of the support column. A positioning foot is fixedly installed above the first spring. A collection bucket is fixedly installed on the positioning foot. A detection mechanism is provided below the collection bucket.

[0007] Preferably, the collecting mechanism further includes a drive disc fixedly installed at one end of the conveyor belt idler and a connecting seat fixedly installed on the collecting hopper, and a connecting rod is installed between the connecting seat and the drive disc.

[0008] Preferably, a rotating shaft is fixedly installed on the connecting seat, and a rotating shaft is also fixedly installed at the edge of the drive disk. One end of the connecting rod is rotatably installed on the connecting seat via the rotating shaft, and the other end of the connecting rod is rotatably installed at the edge of the drive disk via the rotating shaft.

[0009] Preferably, one end of the first spring is fixedly installed on the support column, and the other end of the first spring is fixedly installed on the positioning support leg. The collecting hopper is movably installed below the conveyor belt body through the first spring, and the conveyor belt body is movably installed above the collecting hopper through the conveyor belt idler roller.

[0010] Preferably, the detection mechanism includes a left support and a right support fixedly installed below the collection hopper. A movable shaft is rotatably installed on the left support, and a horizontal rod is rotatably installed on the movable shaft. A trigger plate is fixedly installed at the middle position of the horizontal rod. A second spring is fixedly installed on the right support, and a limit switch is fixedly installed on one side of the right support, with the limit switch located below the horizontal rod.

[0011] Preferably, the right bracket has a mounting groove, and the second spring is mounted on the right bracket through the mounting groove.

[0012] Preferably, the left bracket has a rotating groove, and the movable shaft is rotatably mounted on the left bracket through the rotating groove.

[0013] Preferably, one end of the horizontal rod is rotatably mounted on the left bracket via a movable shaft, and the other end of the horizontal rod is located at the upper end of the second spring. The trigger plate is mounted below the collecting hopper via the horizontal rod, and the trigger plate is aligned with the discharge port at the bottom of the collecting hopper.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this application, the material falling through the crack will fall onto the trigger plate. Under the action of gravity, one end of the horizontal bar will be pressed down. After the horizontal bar is pressed down, it will trigger the limit switch, which will send a stop signal to stop the belt conveyor to prevent the crack from expanding further.

[0016] 2. In this application, when the cracks on the conveyor belt body are small, a small amount of material will fall. At this time, the collecting hopper collects this falling material. During the material collection process, the conveyor belt idlers drive the drive disc to rotate. The rotation of the drive disc causes the connecting rod to reciprocate. The reciprocating motion of the connecting rod causes the collecting hopper to swing, making it easier for the material collected in the collecting hopper to slide onto the trigger disc, thus enabling timely detection of small cracks on the conveyor belt.

[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] Example: Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a novel conveyor belt tear detection device, including a roller bracket 1, a conveyor belt roller 2 rotatably mounted on the roller bracket 1, a conveyor belt body 3 on the conveyor belt roller 2, a collection mechanism 4 between the roller brackets 1, and a detection mechanism 5 below the collection hopper 401.

[0025] Specifically, the cooperation between the idler bracket 1 and the conveyor belt idler 2 can lift the conveyor belt body 3 so that the conveyor belt body 3 can transport materials. The cooperation between the detection mechanism 5 and the collection mechanism 4 can promptly detect small cracks on the conveyor belt, achieving high detection accuracy.

[0026] like Figure 2 and Figure 3As shown, the collecting mechanism 4 includes a support column 404 disposed between the idler roller brackets 1, a crossbar 405 fixedly installed between the support columns 404, a first spring 403 provided at the upper end of the support column 404, a positioning foot 402 fixedly installed above the first spring 403, and a collecting hopper 401 fixedly installed on the positioning foot 402. The collecting mechanism 4 also includes a drive disk 406 fixedly installed at one end of the conveyor belt idler roller 2 and a connecting seat 408 fixedly installed on the collecting hopper 401. A connecting rod 407 is installed between the connecting seat 408 and the drive disk 406. A rotating shaft is fixedly installed on the connecting seat 408, and a rotating shaft is also fixedly installed at the edge of the drive disk 406. One end of the connecting rod 407 is rotatably installed on the connecting seat 408 through the rotating shaft, and the other end of the connecting rod 407 is rotatably installed at the edge of the drive disk 406 through the rotating shaft.

[0027] Specifically, when a small crack appears on the surface of the conveyor belt body 3, some material will slowly leak and fall from the crack. At this time, the collecting hopper 401 located below the conveyor belt will collect this falling material in a timely manner. During the material collection process in the collecting hopper 401, the idler rollers below the conveyor belt will continue to operate, driving the drive disc 406 connected to it to rotate synchronously. During the rotation of the drive disc 406, it will drive the connecting rod 407 to perform regular reciprocating motion through mechanical connection. This reciprocating motion of the connecting rod 407 is further transmitted to the collecting hopper 401, causing it to produce a moderate oscillating motion. This oscillation helps the material collected in the collecting hopper 401 to slide more smoothly onto the trigger disc 505 below. Through this linkage mechanism, even small cracks on the conveyor belt can be detected in time, thereby avoiding greater losses caused by continuous material leakage.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, the detection mechanism 5 includes a left support 501 and a right support 502 fixedly installed below the collection hopper 401. A movable shaft 503 is rotatably installed on the left support 501, and a horizontal rod 504 is rotatably installed on the movable shaft 503. A trigger disc 505 is fixedly installed in the middle of the horizontal rod 504. A second spring 507 is fixedly installed on the right support 502. A limit switch 506 is fixedly installed on one side of the right support 502, and the limit switch 506 is located below the horizontal rod 504. An installation groove is provided on the right support 502, and the second spring 507 is installed on the right support 502 through the installation groove.

[0029] Specifically, when a crack appears on the belt surface during the operation of the belt conveyor, the material spilling from the crack will fall vertically due to gravity, eventually landing precisely on the working surface of the trigger plate 505. As the material accumulates, the weight borne by the trigger plate 505 gradually increases, and this continuously increasing gravity is applied to one end of the horizontal bar 504 through mechanical transmission. As a key component of the lever mechanism, the horizontal bar 504 will produce a significant displacement after being subjected to sufficient downward pressure, causing its other end to descend accordingly. This precise mechanical movement will eventually contact the limit switch 506 installed in the appropriate position, thereby triggering the electrical contacts inside the switch. Once activated, the limit switch 506 immediately sends an emergency stop signal to the control system. Upon receiving this signal, the central control system will quickly cut off the power supply to the belt conveyor, causing the entire conveying system to stop immediately. This rapid-response protection mechanism effectively prevents the belt crack from further expanding during continuous operation, avoiding more serious equipment damage and material loss, and ensuring safe and orderly production.

[0030] Working principle: When there is a crack in the conveyor belt body 3, the material on the conveyor belt body 3 will fall down. The material falling through the crack will fall onto the trigger plate 505. Under the action of gravity, one end of the horizontal bar 504 will be pressed down. After one end of the horizontal bar 504 is pressed down, it will trigger the limit switch 506, which will send a stop signal, and the belt conveyor will stop running to prevent the crack from expanding further. When the crack on the conveyor belt body 3 is small, a small amount of material will fall down. At this time, the collecting hopper 401 collects this falling material. During the collecting process, the conveyor belt idler 2 will drive the drive plate 406 to rotate. When the drive plate 406 rotates, it will drive the connecting rod 407 to reciprocate. When the connecting rod 407 reciprocates, it will drive the collecting hopper 401 to swing, making it easier for the material collected by the collecting hopper 401 to slide onto the trigger plate 505, so as to detect smaller cracks on the conveyor belt in time.
