Description

Technical Field

[0001] The present invention relates to the technical field of transportation, and specifically relates to a pipe belt conveyor belt breakage protection device. Background Art

[0002] The pipe belt conveyor belt breakage protection device is a safety device for a pipe belt conveyor. It mainly uses sensors to monitor the running state of the pipe belt in real time. When abnormal situations such as belt breakage occur in the pipe belt, it can quickly trigger the braking mechanism, thereby forming a clamping protection for the broken pipe belt, preventing the material from driving the pipe belt due to inertia and causing secondary damage, and through an alarm device, reminding the staff to handle it in time to avoid material spillage, thus avoiding accidents such as material spillage, equipment damage and injuries to personnel caused by the breakage of the pipe belt, and ensuring the safe and stable operation of the pipe belt conveyor.

[0003] In the existing pipe belt conveyor belt breakage protection device, when the pipe belt breaks, although the braking mechanism can form a clamping protection for the broken pipe belt, at the moment of pipe belt breakage, the tension balance of the pipe belt is instantly broken. After the originally tight pipe belt loses its restraint, it will undergo a violent elastic deformation, which will cause strong vibrations. Coupled with the high-speed impact of the material and the broken pipe belt, it further exacerbates the amplitude and frequency of the vibration. Inertia causes the material to carry the broken pipe belt and impact the braking mechanism at high speed, not only quickly wearing and deforming the clamping components, but also causing the clamping action to be misaligned or incompletely closed due to the interference of the vibration force and other failure situations. Summary of the Invention

[0026] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0027] 1. Through the sliding component, the biting component, the damping component and the vibration damping conduction component in the braking mechanism, the inertia and vibration generated by the conveyor belt during the clamping of the broken conveyor belt can be transmitted and consumed. Among them, the biting component is used to clamp the conveyor belt when the conveyor belt breaks, and the sliding component is used to cooperate with the biting component to move in the base after clamping the conveyor belt, so as to increase the buffering distance of the biting component. The damping component and the vibration damping conduction component cooperate with each other to guide the vibration generated when the biting component clamps the broken conveyor belt, and consume and offset the vibration through the vibration damping conduction component, so as to reduce the vibration amplitude of the broken conveyor belt when the biting component clamps it, ensuring the stability and reliability of the clamping action of the biting component, preventing the clamping failure caused by vibration, and avoiding a large amount of materials from spilling or hitting other components of the pipe conveyor due to inertia and vibration, reducing the risk of material waste and equipment failure.

[0028] 2. Through the energy-consuming mechanism and the guiding mechanism, the inertia of the broken conveyor belt buffered by the sliding component can be guided and offset. Among them, by using the power component, the conveyor belt component, the resistance component and the compression component in the energy-consuming mechanism, the inertia of the broken conveyor belt can be consumed to achieve the purpose of reducing the inertia acting on the sliding component. Among them, the power component is used to receive and conduct the inertial force transmitted by the guiding mechanism, and the inertial force transmitted to the power component will further drive the conveyor belt component to rotate in the outer box, and stir the suspended thick liquid contained in the outer box of the resistance component arranged in the conveyor belt component. When the resistance component stirs the suspended thick liquid, the suspended thick liquid has high viscosity and will generate a strong and continuous resistance to the resistance component during the stirring process. This resistance can effectively consume the inertial force and greatly reduce the effect of inertia on the sliding component. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0044] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] The present invention will be further described below with reference to the embodiments.

[0046] Embodiment: Refer to Figures 1 to 13 , a pipe belt conveyor belt break protection device, comprising:

[0047] A base 1, and two slide bars 12 are fixedly connected to both sides of the base 1 in the length direction;

[0048] A braking mechanism 2, the braking mechanism 2 includes a sliding component 21 arranged in the slide bar 12, a biting component 25 is arranged at the central position of the sliding component 21, a damping component 27 is arranged at the bottom of the biting component 25, and a plurality of springs 28 and a plurality of damping conduction components 29 are alternately arranged at the bottom of the biting component 25;

[0049] An energy-consuming mechanism 3, the energy-consuming mechanism 3 includes an outer box 31 fixedly connected to the upper end surface of one side of the base 1 in the width direction, and a suspended thick liquid is contained in the outer box 31;

[0050] At least three power components 33 and two compression components 36 are linearly arranged in the outer box 31, a conveyor belt component 34 is jointly arranged on the outer peripheral surfaces of the two power components 33, and a plurality of resistance components 35 are arranged in a rectangular array on the upper end surface of the conveyor belt component 34;

[0051] A guiding mechanism 4, the guiding mechanism 4 is arranged on both sides inside the top of the base 1 in the width direction, and the guiding mechanism 4 is connected to the biting component 25.

[0052] The sliding component 21 in the braking mechanism 2 enables the engaging component 25 in the braking mechanism 2 to move in the base 1 under the influence of inertia after clamping the broken conveyor belt, so as to achieve the guidance of inertia by the guiding mechanism 4. The engaging component 25 clamps the broken conveyor belt, and the shock-absorbing conduction component 29 cooperates with the spring 28 to guide and buffer the vibration fluctuation of the conveyor belt when the engaging component 25 clamps the broken conveyor belt. The shock-absorbing component 27 is used to receive the vibration wave guided by the shock-absorbing conduction component 29 and consume the vibration wave with its weight. The energy-consuming mechanism 3 utilizes the power converted from the inertial force transmitted to the power component 33 by the guiding mechanism 4 to drive the conveyor belt assembly 34 to rotate, and then enables the resistance component 35 arranged in the conveyor belt assembly 34 to rotate in the outer box 31 and stir the suspended thick liquid contained in the outer box 31. When the resistance component 35 stirs the suspended thick liquid, the suspended thick liquid has high viscosity and will generate a strong and continuous resistance to the resistance component 35 during the stirring process, and this resistance can effectively consume the inertial force.

[0053] Refer to Figures 1 to 6 , two slide bars 12 on each side are symmetrically fixedly connected from top to bottom along the length direction of the base 1. A controller is fixedly connected to the side surface of the base 1. Two warning lights 11 are symmetrically fixedly connected to the upper end surface of the base 1 on the side far from the outer box 31, and the warning lights 11 are electrically connected to the controller;

[0054] The sliding component 21 includes sliders 211 slidably connected to the rod bodies of the slide bars 12. A linkage rod 212 is fixedly connected to the opposite surfaces of the two sliders 211 in the width direction of the base 1. A fixing plate 213 is fixedly connected to the opposite surfaces of the two sliders 211 in the length direction of the base 1. A bottom clamping block 214 is fixedly connected to the upper end surface of the fixing plate 213 at the bottom of the base 1;

[0055] Positioning plates 22 are fixedly connected to the upper end surfaces of the two sliders 211 at the top of the base 1. A multi-chamber air bag tube 23 is fixedly connected to the side of the positioning plate 22 located on one side of the outer box 31. The multi-chamber air bag tube 23 is filled with air. An electro-hydraulic rod 24 is fixedly connected to the center position of the upper end surface of the fixing plate 213 at the top of the base 1, and the electro-hydraulic rod 24 is electrically connected to the controller.

[0056] The slider 211 in the sliding component 21 enables the engaging component 25 to slide in the base 1, and the bottom clamping block 214 is used to provide enough friction for the engaging component 25 to clamp the broken pipe belt. When the sliding component 21 moves in the base 1 under the inertia of the engaging component 25 clamping the broken pipe belt, it will squeeze the multi-chamber air bag tube 23. When the multi-chamber air bag tube 23 is compressed, the air in the multi-chamber air bag tube 23 enters the energy-consuming mechanism 3, changing the internal pressure of the energy-consuming mechanism 3. The amount of air delivered by the multi-chamber air bag tube 23 to the energy-consuming mechanism 3 is determined by the magnitude of the inertial force received by the sliding component 21 and the sliding distance in the base 1.

[0057] Refer to Figure 5 、 Figure 7 The bite assembly 25 includes two pressure rods 252 movably inserted on both sides of the fixed plate 213 centered on the electro-hydraulic rod 24. A connecting plate 251 is fixedly connected to the upper end surfaces of the two pressure rods 252, and the telescopic end of the electro-hydraulic rod 24 is fixedly connected to the side of the connecting plate 251 facing the fixed plate 213. The other ends of the two pressure rods 252 are fixedly connected to a top plate 253;

[0058] The top plate 253 is divided into a clamping area and a damping area along the length direction, and the clamping area faces the side of the warning light 11. A top clamping block 26 is fixedly connected to the bottom of the clamping area, and the top clamping block 26 corresponds to the position of the bottom clamping block 214.

[0059] When the electro-hydraulic rod 24 in the bite assembly 25 drives the connecting plate 251 to descend due to the fracture of the pipe belt, as the connecting plate 251 descends, it further drives the pressure rod 252 to descend. As the pressure rod 252 descends, it will clamp the pipe belt located between the top clamping block 26 and the bottom clamping block 214 through the top plate 253.

[0060] Refer to Figures 7 to 9 A spring 28 is fixedly connected to the bottom of the damping area, and the other end of the spring 28 is fixedly connected to a buffer plate 210;

[0061] The vibration damping conduction assembly 29 includes a first fixing block 291 fixedly connected to the bottom of the damping area. Two elastic support ropes 294 are sleeved on opposite sides of the first fixing block 291. The other sides of the two elastic support ropes 294 are jointly sleeved with a second fixing block 293. The side of the second fixing block 293 away from the first fixing block 291 is fixedly connected to the upper end surface of the buffer plate 210. A vibration conduction rod 292 is fixedly connected to the center position of the second fixing block 293. The other end of the vibration conduction rod 292 penetrates through the first fixing block 291 and the damping area and extends above the damping area.

[0062] When the buffer plate 210 contacts the fractured pipe belt and presses the pipe belt, the spring 28 will be compressed. The vibration damping conduction assembly 29 uses the elastic support ropes 294 to support the first fixing block 291 and the second fixing block 293. When the buffer plate 210 contacts the fractured pipe belt and presses the pipe belt, the first fixing block 291 and the second fixing block 293 will also approach each other due to the pressure. At this time, the elastic support ropes 294 play a role in buffering the vibration wave, and the vibration wave received by the second fixing block 293 in the buffer plate 210 is guided to the vibration damping assembly 27 through the vibration conduction rod 292.

[0063] Refer to Figure 7, the shock absorption assembly 27 includes a concave plate 271 fixedly connected to one end of the vibration guide rod 292 away from the second fixed block 293. On both sides of the upper end face of the shock absorption area centered on the concave plate 271, pulley groups 272 are fixedly connected. The pulley groups 272 are composed of brackets and pulleys. The brackets are fixedly connected to the shock absorption area, and the pulleys are rotatably connected to the brackets. On both sides of the concave plate 271 facing the pulley groups 272, elastic ropes 273 are fixedly connected, and the rope bodies of the elastic ropes 273 are in contact with the pulleys. The other side of the elastic ropes 273 is fixedly connected to counterweight blocks 274.

[0064] The concave plate 271 in the shock absorption assembly 27 is used to receive the vibration wave guided by the vibration guide rod 292, and the elastic ropes 273 use the counterweight blocks 274 to consume the vibration wave guided into the concave plate 271 through weight. The pulley groups 272 are used to ensure the smoothness when the elastic ropes 273 drive the counterweight blocks 274 to move up and down.

[0065] Refer to Figures 9 to 11 , the power assembly 33 includes rotating rods 331 rotatably connected to both sides in the length direction inside the outer box 31. At both ends of the rotating rods 331, sawtooth gears 332 are fixedly connected;

[0066] One side of the outer box 31 away from the base 1 is rotatably connected to a rotating shaft 32, and one end of the rotating shaft 32 close to the outer box 31 penetrates the outer box 31 and is fixedly connected to any one of the rotating rods 331.

[0067] The rotating rods 331 can further transfer and convert the inertia received by the sliding assembly 21 guided by the guiding mechanism 4, thereby driving the rotation of the sawtooth gears 332.

[0068] Refer to Figures 11 to 12 , the conveyor belt assembly 34 includes a toothed groove conveyor belt 341 engaged with the outer circumferential surfaces of the two sawtooth gears 332. On the opposite surfaces of the two toothed groove conveyor belts 341, an elastic conveyor belt 342 is fixedly connected;

[0069] The resistance assembly 35 includes a fixed rod 353 fixedly connected to the upper end face of the elastic conveyor belt 342. On the upper end face of the fixed rod 353, a conical box 351 is fixedly connected. On both inner side walls of the conical box 351, a plurality of inclined plates 352 are linearly arrayed and fixedly connected. In the middle of the conical box 351, a multi-rhombus rod 354 is rotatably connected.

[0070] The rotation of the sawtooth gears 332 can drive the rotation of the toothed groove conveyor belt 341 and the elastic conveyor belt 342. As the elastic conveyor belt 342 rotates, the conical box 351 of the resistance assembly 35 in the elastic conveyor belt 342 combines with the internal inclined plates 352 and the multi-rhombus rod 354 to stir the suspended thick liquid contained in the outer box 31, thereby consuming the inertial energy transmitted by the guiding mechanism 4.

[0071] Refer to Figure 11 ,Figure 13 , the compression assembly 36 includes a compression box 361 and a guide plate 363 fixedly connected to the inner walls on both sides in the length direction of the outer box 31 respectively, and the compression box 361 is located on one side of the rotating shaft 32. Elastic rods 362 are fixedly connected to both sides of the compression box 361, and the other side of the elastic rods 362 is fixedly connected to the guide plate 363. A connecting block 37 is fixedly connected to the outer box 31 on one side of the rotating shaft 32, and one side of the connecting block 37 facing the outer box 31 penetrates the outer box 31 and communicates with the compression box 361. The other side of the connecting block 37 is fixedly connected to a connecting pipe 371, and the other end of the connecting pipe 371 is fixedly connected to the side of the multi-chamber airbag pipe 23 away from the positioning plate 22.

[0072] The connecting pipe 371 of the compression box 361 in the compression assembly 36 is used to receive the air compressed and conveyed by the multi-chamber airbag pipe 23, so that the compression box 361 expands, and then changes the pressure of the part in the outer box 31 without the suspended thick liquid, so as to enhance the resistance of the suspended thick liquid to the suspended thick liquid.

[0073] Refer to Figure 4 , the guiding mechanism 4 includes a hollow frame 41 fixedly connected inside the base 1 in the width direction. A threaded rod 42 is rotatably connected inside the hollow frame 41. A threaded slider 43 is slidably connected inside the hollow frame 41, and the threaded slider 43 is threadedly connected to the rod body of the threaded rod 42. The upper end surface of the threaded slider 43 is fixedly connected to the bottom of the fixing plate 213 of the electro-hydraulic rod 24 through an anchoring rod. One side of the base 1 facing the outer box 31 is rotatably connected to a torsion rod 44, and one end of the torsion rod 44 facing the base 1 penetrates the base 1, the hollow frame 41 and is fixedly connected to the threaded rod 42. The other side of the torsion rod 44 is belt-drivenly connected to the rotating shaft 32.

[0074] The anchoring rod of the threaded slider 43 in the guiding mechanism 4 is used to transmit the force when the sliding assembly 21 slides to the threaded slider 43. Then, through the movement of the threaded slider 43 in the threaded rod 42, the threaded rod 42 rotates, and through the belt-driven connection between the torsion rod 44 and the rotating shaft 32, the rotational force of the threaded rod 42 is transmitted to the rotating rod 331.

[0075] The operation principle of this embodiment is specifically as follows:

[0076] The first step: First, the braking of the broken transmission of this equipment (the equipment in this solution refers to the pipe belt machine belt break protection device) needs to cooperate with a detector for detecting the breakage of the pipe belt. Therefore, a detector for detecting the breakage of the pipe belt is provided in front of the equipment position, such as: a tension detector, a position detector, etc. Since the detectors are all prior arts, they are not shown in the figure, and the detectors are electrically connected to the controller.

[0077] Among them, at the moment when the pipe belt breaks, the detector detects an abnormality and transmits the signal to the controller. After receiving the pipe belt break signal transmitted by the detector, the controller immediately activates the braking mechanism 2 and activates the electro-hydraulic rod 24 in the braking mechanism 2. With the activation of the electro-hydraulic rod 24, the telescopic end of the electro-hydraulic rod 24 drives the connecting plate 251 to descend. Since the connecting plate 251 is connected to the two pressure rods 252, when the connecting plate 251 descends, it drives the pressure rods 252 to move downward synchronously. As the pressure rods 252 move downward, the top plate 253 descends accordingly, and then the top clamp 26 approaches the bottom clamp 214. Since the pipe belt is located between the top clamp 26 and the bottom clamp 214, when the top clamp 26 and the bottom clamp 214 fit together, the broken pipe belt is firmly clamped. Moreover, the top clamp 26 and the bottom clamp 214 are made of anti-slip and wear-resistant materials, such as high-strength rubber added with tungsten carbide particles, which can provide sufficient friction when clamping the pipe belt to ensure that the pipe belt will not escape due to inertia and effectively prevent the continuous sliding of the pipe belt.

[0078] Step 2: At the moment when the top clamp 26 and the bottom clamp 214 of the biting assembly 25 clamp the pipe belt, due to the inertia of the pipe belt, the biting assembly 25 will drive the sliding assembly 21 to slide on the base 1 (in the initial state, the sliding assembly 21 is located on the side of the base 1 away from the outer box 31, and the sliding distance of the sliding assembly 21 on the base 1 is determined by the inertia when clamping the pipe belt). During the sliding process of the sliding assembly 21, the slider 211 located on the upper end surface of the base 1 will squeeze the multi-chamber air bladder tube 23, causing the air filled in the multi-chamber air bladder tube 23 to be continuously squeezed out (the multi-chamber air bladder tube 23 is made of an elastic material and has good elasticity and sealing performance). The squeezed air enters the compression box 361 of the compression assembly 36 through the connecting pipe 371, so that the compression box 361 expands under the action of the air (the expansion size of the compression box 361 is determined by the inertia when clamping the pipe belt), and then changes the pressure of the non-suspended thick liquid part in the outer box 31 (suspended thick liquid: such as silica gel suspension, sodium carboxymethyl cellulose (CMC) solution, and sodium silicate suspension, etc.). Because according to the ideal gas state equation PV = nRT (where P is pressure, V is volume, n is the amount of substance, R is a constant, and T is temperature), when the temperature and the amount of substance are approximately constant, the expansion of the compression box 361 will increase the pressure in the outer box 31 and enhance the resistance of the suspended thick liquid to the subsequent stirring action;

[0079] Meanwhile, as the sliding component 21 continues to slide, more and more air enters the compression box 361, causing it to expand continuously. The movement of the sliding component 21 is connected to the fixed plate 213 through the threaded slider 43 of the guiding mechanism 4. Therefore, as the sliding component 21 moves, the threaded slider 43 performs a threaded drive on the threaded rod 42, prompting the threaded rod 42 to rotate. The rotation of the threaded rod 42 is transmitted to the rotating shaft 32 through the torsion bar 44 and the belt drive, driving the rotating rod 331 of the power component 33 to rotate. The rotating rotating rod 331 uses the sawtooth gears 332 at both ends to drive the toothed groove conveyor belt 341 and the elastic conveyor belt 342 of the conveyor belt component 34 to rotate. As the elastic conveyor belt 342 rotates, the resistance component 35 on the elastic conveyor belt 342 rotates accordingly. Inside the conical box 351 of the resistance component 35, the inclined plate 352 and the multi-ridge rod 354 stir the suspended thick liquid in the outer box 31. Since the suspended thick liquid has high viscosity and the physical state of the suspended thick liquid changes after the pressure in the outer box 31 increases. From a microscopic perspective, the increase in pressure reduces the molecular spacing of the suspended thick liquid and enhances the intermolecular interaction force. From a macroscopic perspective, according to Stokes' law F = 6πηrv, although the size (particle radius r) and the moving speed v of the resistance component 35 remain unchanged, the increase in pressure makes the viscosity coefficient η of the suspended thick liquid equivalently increase. For example, when the pressure increases, the suspended thick liquid with an original viscosity coefficient of 10 Pa·s may have an equivalent viscosity coefficient increased to 12 Pa·s. Then, according to the formula calculation, the resistance F received by the resistance component 35 will also increase correspondingly. The greater the resistance caused by the suspended thick liquid to the resistance component 35, the more energy is consumed by the resistance component 35 when stirring the liquid. This means that the inertial force of the broken pipe belt can be more effectively consumed, further enhancing the consumption effect of the energy-consuming mechanism 3 on the inertial force of the broken pipe belt.

[0080] Step 3: While the pipe belt drives the sliding component 21 to slide in the base 1 due to inertia, since the pipe belt is in a taut state before fracture, the huge inertia and elastic deformation after fracture will cause strong vibrations. Therefore, when the buffer plate 210 contacts the vibrating fractured pipe belt, according to Hooke's law F = kx (where F is the spring elastic force, k is the spring stiffness coefficient, and x is the spring deformation), the spring 28 will be elastically deformed due to extrusion, absorbing part of the vibration energy and reducing the impact force of the vibration, achieving a preliminary buffering effect. When the buffer plate 210 is impacted by vibration, the first fixing block 291 and the second fixing block 293 approach due to the pressure, and the elastic support rope 294 stretches and contracts by virtue of its own elasticity, further buffering the vibration wave and reducing the transmission of the vibration. At the same time, the vibration guiding rod 292 guides the vibration wave received by the buffer plate 210 to the vibration damping component 27. After the concave plate 271 receives the vibration wave guided by the vibration guiding rod 292, the elastic rope 273 drives the counterweight 274 to move up and down with the assistance of the pulley block 272. According to the law of conservation of energy, the gravitational potential energy and kinetic energy of the counterweight 274 are converted into each other during the movement, converting the energy of the vibration wave into other forms of energy (such as heat energy, etc.) and consuming it, greatly reducing the vibration amplitude, ensuring the stable and reliable clamping action of the clamping component 25, avoiding clamping failure caused by vibration, and ensuring the safe operation of the equipment.

[0081] Among them, it should be specifically noted that while the detector feeds back information to the controller, the controller synchronously controls the warning light 11 to turn on, reminding the staff to handle it in time to avoid more serious accidents caused by the fracture of the pipe belt.
