Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, and more specifically, to an anti-tearing device for a belt conveyor. Background Art

[0002] In the process flow, industrial mining materials are mostly transported by belt conveyors. Generally, iron removers are installed on each belt. However, the iron removal effect of the iron remover is limited, and there is a risk of the iron remover failing and shutting down. Once the iron remover is shut down and demagnetized, the iron will fall and scratch the belt. In addition, other foreign objects will also scratch the belt, causing the belt to tear. This not only easily causes material waste, but also causes a lot of economic losses every year due to such accidents. Therefore, a device that can detect belt tearing is needed. When the belt is torn, the relevant transportation device can be stopped in time to reduce losses.

[0003] The Chinese patent announcement number is CN217304936U, and the announcement date is August 26, 2022. The name of the invention is a mining conveyor belt tear detection device. The application sets parallel lights and uses a camera to feed back pictures of the conveyor belt in real time, and processes the pictures to determine whether the surface of the conveyor belt is torn. In the above application, the camera can monitor the transportation of the conveyor belt in real time, but when it is used, due to the large amount of dust at the construction site, the pictures of the conveyor belt taken will have defects, which can easily cause misjudgment of the machine. Although a vacuum cleaner is set in the above application document, the above situation is possible. Utility Model Content

[0004] The utility model overcomes the problem in the prior art that although the condition of the belt can be monitored by images to achieve the purpose of tear prevention, due to the large amount of dust on the construction site, misjudgment may easily occur, causing the belt conveyor to stop working due to misjudgment. An anti-tear device for a belt conveyor is provided, which can use the material that penetrates from the tear to trigger a sensor when the belt is torn, so as to stop the relevant conveyor from working, thereby effectively preventing the loss from expanding.

[0006] In the utility model, when the belt is torn, the material will fall onto the weight-supporting plate from the gap at the tear, and the weight-supporting plate moves downward under the action of gravity, and the weight-supporting plate moves downward against the action of the damping member, so that the weight-supporting plate triggers the detection device, and the micro switch at this time stops the relevant transport equipment from working, and stops the upstream conveyor belt from working, thereby reducing losses. In addition, the weight-supporting plate in the present application can catch a part of the material, and can also reduce a part of the losses.

[0007] Preferably, the vertical sliding assembly includes a slide groove arranged on the mounting member along the gravity direction, a slider arranged on the weight-supporting plate and slidably matched with the slide groove, and a damping member is arranged between the slider and the mounting bracket.

[0008] Through the cooperation of the slider and the slide groove, the weight-supporting plate can slide along the vertical direction.

[0009] Preferably, two vertically arranged sliding posts cooperate to form a sliding groove, waist-shaped grooves are arranged on both sides of the sliding block, and the waist-shaped grooves on both sides of the sliding block cooperate with the sliding posts on both sides respectively.

[0012] The abutting spring in this embodiment abuts between the first hole and the second hole. The first hole and the second hole can limit the damping member, thereby ensuring that the spring abuts between the support plate and the slider.

[0013] Preferably, the damping element is a spring.

[0014] The spring can maintain its original state for a long time within its elastic limit, thereby improving the stability of the equipment.

[0016] The detection device is arranged at the bottom of the second hole, so that when the spring is compressed, the detection device can be triggered immediately.

[0017] Preferably, the detection device is a micro switch.

[0018] The micro switch has the advantage of high sensitivity and can be triggered quickly, causing the relevant equipment to stop working in time.

[0019] Preferably, the vertical sliding assemblies are arranged on both sides of the weight-supporting tray in the length direction, and each weight-supporting tray is provided with two groups of vertical sliding assemblies.

[0020] Compared with the prior art, the beneficial effect of the utility model is that when the belt is torn, the material will fall onto the weight-supporting plate from the gap at the tear, and the weight-supporting plate moves downward under the action of gravity, and the weight-supporting plate moves downward against the action of the damping member, so that the weight-supporting plate triggers the detection device, and the micro switch at this time stops the relevant transport equipment from working, and stops the upstream conveyor belt of the belt from working, thereby reducing losses. In addition, the weight-supporting plate in the present application can catch part of the material, and can also reduce part of the losses. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0032] Example 1: Reference Figures 1 to 9 As shown, a belt conveyor tear prevention device comprises: a mounting frame 1, a weight-supporting plate 2 arranged on the mounting frame 1, vertical sliding components 3 are arranged on both sides of the weight-supporting plate 2 on the mounting frame 1, and the weight-supporting plate 2 is installed on the vertical sliding components 3; a detection device 4 is arranged on the mounting frame 1, and a damping member 5 is arranged between the mounting frame 1 and the weight-supporting plate to maintain a distance between the two; after the weight-supporting plate 2 receives the material, it overcomes the elastic force of the damping member 5 and slides downward, and the weight-supporting plate triggers the detection device 4.

[0033] The mounting frame 1 includes two parallel trusses 11, two transport shafts 12 are arranged at both ends of the trusses 11, one of the two transport shafts 12 is connected to an output motor 13, and belts are respectively wound around the two transport shafts 12. The output motor 13 drives one of the transport shafts 12 to work, so that the belt can move on the two transport shafts 12, thereby realizing the transportation of materials. The position where the belt is located above the two transport shafts 12 is the upper belt 14, and the position where the belt is located below the two transport shafts 12 is the lower belt 15. The belt conveyor anti-tear device is arranged between the upper belt 14 and the lower belt 15.

[0034] A support plate 16 is provided on each of the two trusses 11. A rib is provided at the bottom of the support plate 16 to strengthen its support strength. The support plate 16 mainly supports the anti-tearing device of the entire belt conveyor. The vertical sliding assembly 3 is provided on the support plate 16, and the supporting plate 2 is provided on the support plate 16 through the vertical sliding assemblies 3 on both sides thereof. When the supporting plate is subjected to gravity, it can slide in the vertical direction.

[0035] The vertical sliding assembly 3 in this embodiment includes a slide groove 31 arranged on the mounting member along the gravity direction, a slider 32 fixedly arranged on the weight-supporting plate 2 and slidingly matched with the slide groove 31, and a damping member 5 arranged between the slider 32 and the mounting bracket. The damping member 5 in this embodiment is a spring. The spring abuts between the slider 32 and the support plate 16, and the spring elastic coefficient in this embodiment is relatively small. Of course, the damping member 5 in this embodiment can also be set to other elastic structures, such as a rubber structure.

[0036] The slide groove 31 in this embodiment is formed by the cooperation of two vertically arranged slide posts 33, which are fixedly arranged on the support plate 16, and the two cooperate to form the vertical slide groove 31. In order to make the slider 32 more stable when sliding, waist grooves 34 are arranged on both sides of the slider 32, and the waist grooves 34 on both sides of the slider 32 cooperate with the slide posts 33 on both sides respectively. The waist grooves 34 play a guiding role, thereby guiding the sliding of the slider 32.

[0037] The vertical sliding components 3 are arranged on both sides of the length direction of the weight-supporting plate 2, and each weight-supporting plate 2 is provided with two sets of vertical sliding components 3. That is, two vertically arranged slide grooves 31 are arranged on one side of each weight-supporting plate 2, and two sliders 32 are arranged on each weight-supporting plate 2 to match the two vertical slide grooves 31 respectively.

[0038] A first hole 35 is provided on the lower end surface of the slider 32, and a second hole 36 is provided on the mounting frame 1. The second hole 36 and the first hole 35 are coaxially arranged, and the damping member 5 abuts between the second hole 36 and the first hole 35. The abutting spring in this embodiment abuts between the first hole 35 and the second hole 36, and the first hole 35 and the second hole 36 can limit the spring, thereby ensuring that the spring abuts between the support plate 16 and the slider 32.

[0039] The detection device 4 is arranged at the bottom of the second hole 36, and the spring is arranged at the periphery of the detection device 4. Through the above arrangement, when the weight-carrying plate 2 is pressed downward by gravity to overcome the force of the spring, the spring is compressed, so that the weight-carrying plate 2 acts on the detection device 4, and the detection device 4 detects the effect of pressure, thereby stopping the operation of the relevant transportation equipment and reducing losses.

[0040] The detection device 4 in this embodiment is a micro switch arranged in the second hole 36. Once the weight tray 2 acts on the micro switch due to gravity, the micro switch will cut off the switch, causing the relevant transportation equipment to stop working and reduce losses.

[0041] The working principle of this embodiment is as follows: the belt conveyor tear-proof device is set between the upper belt 14 and the lower belt 15 of the belt conveyor, and is set at the end of the belt conveyor. Because the end of the belt conveyor usually receives materials from the upper hopper, when the materials fall from the hopper to the end of the belt conveyor, the belt will be subjected to a large force due to the gravity of the materials. Therefore, the belt at the end of the belt conveyor is the most likely to tear.

[0042] When the belt is torn, the material will fall onto the weight-supporting plate from the gap at the tear. The weight-supporting plate moves downward under the action of gravity, overcoming the action of the spring to move downward, causing the weight-supporting plate to trigger the micro switch. At this time, the micro switch stops the relevant transportation equipment and the upstream conveyor belt of the belt, thereby reducing losses. In addition, the weight-supporting plate in the present application can catch part of the material, which can also reduce some losses.

[0043] Example 2: Reference Figures 1 to 9As shown, a belt conveyor tear prevention device comprises: a mounting frame 1, a weight-supporting plate 2 arranged on the mounting frame 1, vertical sliding components 3 are arranged on both sides of the weight-supporting plate 2 on the mounting frame 1, and the weight-supporting plate 2 is installed on the vertical sliding components 3; a detection device 4 is arranged on the mounting frame 1, and a damping member 5 is arranged between the mounting frame 1 and the weight-supporting plate to maintain a distance between the two; after the weight-supporting plate 2 receives the material, it overcomes the elastic force of the damping member 5 and slides downward, and the weight-supporting plate triggers the detection device 4.

[0044] The mounting frame 1 includes two parallel trusses 11, two transport shafts 12 are arranged at both ends of the trusses 11, one of the two transport shafts 12 is connected to an output motor 13, and belts are respectively wound around the two transport shafts 12. The output motor 13 drives one of the transport shafts 12 to work, so that the belt can move on the two transport shafts 12, thereby realizing the transportation of materials. The position where the belt is located above the two transport shafts 12 is the upper belt 14, and the position where the belt is located below the two transport shafts 12 is the lower belt 15. The belt conveyor anti-tear device is arranged between the upper belt 14 and the lower belt 15.

[0045] Two support plates 16 are arranged on the two trusses 11. Ribs are arranged at the bottom of the support plates 16 to strengthen the support strength. The support plates 16 mainly support the anti-tearing device of the entire belt conveyor. The vertical sliding assembly 3 is arranged on the support plate 16, and the supporting plate 2 is arranged on the support plate 16 through the vertical sliding assemblies 3 on both sides thereof. When the supporting plate is subjected to gravity, it can slide in the vertical direction.

[0046] The vertical sliding assembly 3 in this embodiment includes a slide groove 31 arranged on the mounting member along the gravity direction, a slider 32 arranged on the weight-carrying plate 2 and slidingly matched with the slide groove 31, and a damping member 5 arranged between the slider 32 and the mounting bracket. The damping member 5 in this embodiment is a spring, and the spring elastic coefficient in this embodiment is relatively small. The spring abuts between the slider 32 and the support plate 16. Of course, the damping member 5 in this embodiment can also be set to other elastic structures, such as a rubber structure.

[0047] The slide groove 31 in this embodiment is formed by the cooperation of two vertically arranged slide posts 33, which are fixedly arranged on the support plate 16, and the two cooperate to form the vertical slide groove 31. In order to make the slider 32 more stable when sliding, waist grooves 34 are arranged on both sides of the slider 32, and the waist grooves 34 on both sides of the slider 32 cooperate with the slide posts 33 on both sides respectively. The sleeve hole plays a guiding role, thereby guiding the sliding of the slider 32.

[0048] The vertical sliding components 3 are arranged on both sides of the length direction of the weight-supporting plate 2, and each weight-supporting plate 2 is provided with two sets of vertical sliding components 3. That is, two vertically arranged slide grooves 31 are arranged on one side of each weight-supporting plate 2, and two sliders 32 are arranged on each weight-supporting plate 2 to match the two vertical slide grooves 31 respectively.

[0049] A first hole 35 is provided on the lower end surface of the slider 32, and a second hole 36 is provided on the mounting frame 1. The second hole 36 and the first hole 35 are coaxially arranged, and the damping member 5 abuts between the second hole 36 and the first hole 35. The abutting spring in this embodiment abuts between the first hole 35 and the second hole 36, and the first hole 35 and the second hole 36 can limit the spring, thereby ensuring that the spring abuts between the support plate 16 and the slider 32.

[0050] The detection device 4 is arranged at the bottom of the second hole 36, and the spring is arranged at the periphery of the detection device 4. Through the above arrangement, when the weight-carrying plate 2 is pressed downward by gravity to overcome the force of the spring, the spring is compressed, so that the weight-carrying plate 2 acts on the detection device 4, and the detection device 4 detects the effect of pressure, thereby stopping the operation of the relevant transportation equipment and reducing losses.

[0051] The detection device 4 in this embodiment is a gravity sensor arranged in the second hole 36. The top contact head of the gravity sensor is in contact with the load-supporting plate. Once the load-supporting plate 2 acts on the gravity sensor due to gravity, the control system senses a large gravity change through the gravity sensor, and the control system will cut off the switch of the relevant equipment, causing the relevant transportation equipment to stop working, thereby reducing losses.

[0052] The working principle of this embodiment is as follows: the belt conveyor tear-proof device is set between the upper belt 14 and the lower belt 15 of the belt conveyor, and is set at the end of the belt conveyor. Because the end of the belt conveyor usually receives materials from the upper hopper, when the materials fall from the hopper to the end of the belt conveyor, the belt will be subjected to a large force due to the gravity of the materials. Therefore, the belt at the end of the belt conveyor is the most likely to tear.

[0053] When the belt is torn, the material will fall onto the weight-supporting plate from the gap at the tear. The weight-supporting plate moves downward under the action of gravity, overcoming the action of the spring to move downward, causing the weight-supporting plate to trigger the gravity sensor. The control system senses a large gravity change through the gravity sensor, and the control system will cut off the switch of the relevant equipment, causing the upstream conveyor belt of the belt to stop working, thereby reducing losses. In addition, the weight-supporting plate in the present application can catch part of the material, which can also reduce some losses.

[0054] Example 3: Reference Figure 6As shown, the structure of this embodiment is similar to that of the embodiment 2, except that an adjusting threaded hole 37 is provided at the bottom end of the second hole 36, an adjusting thread matched with the adjusting threaded hole 37 is provided on the outer wall of the gravity sensor, and the gravity sensor is fixedly arranged in the adjusting threaded hole 37 by threaded connection. Therefore, the position of the gravity sensor can be adjusted by rotating the gravity sensor, thereby adjusting the distance between the top of the gravity sensor and the weight-supporting plate, thereby changing the triggering sensitivity of the gravity sensor.
