Description

Technical Field

[0001] The invention belongs to the technical field of belt conveyors, in particular to a deviation correcting device for belt conveyors. Background Art

[0002] Belt conveyor is also called belt conveyor or belt conveyor. It is a kind of continuous transportation equipment with traction. Its working principle is to drive the drum to rotate through the motor or other power, and the drum drives the belt to move, so as to transport materials from one place to another. Belt conveyor has a wide range of uses, mainly suitable for coal, mining, building materials, chemical industry, petroleum and transportation and other industries.

[0003] When the staff uses a belt conveyor to convey materials, they will place the materials steadily on the feed end of the belt conveyor, then start the motor of the belt conveyor to make the drum start to rotate, thereby driving the belt to move. When the materials are conveyed to the unloading end of the belt, they will be unloaded to the target location, and then the material transportation will be completed.

[0004] During long-term use and observation, it was found that in the process of using a belt conveyor to transport materials, the position deviation of the belt conveyor will cause the material to scatter from the edge or gap of the belt, resulting in material loss.

[0005] To this end, the present invention provides a belt conveyor deviation correcting device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one problem raised in the background technology, a belt conveyor deviation correcting device is proposed.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: a belt conveyor deviation correction device described in the present invention comprises a base; a support frame is fixedly connected to the top side wall of the base; the support frames are a pair and are symmetrically arranged on both sides of the base; a motor is provided in the middle of the side wall of one side of the support frame; a conveying roller is fixedly connected to the output end of the motor; the conveying rollers are multiple and are evenly arranged between a pair of support frames; the conveying rollers and the support frame are rotatably connected; a conveying belt is rotatably connected between the multiple conveying rollers; an electric push rod is fixedly connected to the middle of the side wall of the support frame; a movable plate is fixedly connected to the output end of the electric push rod; a plurality of limit plates are fixedly connected to the middle of the side wall of the movable plate; the limit plate is sleeved on the outside of the conveying roller; the conveying A detection component is provided above the conveyor belt; in this step, a conveyor belt, an electric push rod, a movable plate and a limit plate are arranged. When the conveyor belt deviates from the predetermined track, the electric push rod is started to make adjustments without manual intervention to ensure that the conveyor belt remains on the correct running path, and the deviation correction device driven by the electric push rod can be flexibly adjusted according to the actual deviation of the conveyor belt to adapt to the requirements of different materials and working conditions to ensure that the conveyor belt always remains in the correct position. By timely correcting the deviation of the conveyor belt, the friction between the conveyor belt and the support frame can also be reduced, thereby extending the service life of the conveyor belt and reducing the replacement cost caused by wear. At the same time, it can also reduce the scattering and waste of materials caused by the deviation of the conveyor belt.

[0008] Preferably, a fixing rod is fixedly connected to the middle of the side wall of the movable plate; the fixing rods are multiple and are regularly arranged in a linear array on the side wall of the movable plate; a roller is rotatably connected to the middle of the side wall of the fixing rod; the roller is arranged above the conveyor belt; this step, by setting the fixing rod and the roller, can make it easier to adjust the position of the material as needed during the conveying process, ensuring that the material arrives at the designated position accurately, and the roller can also make the material move smoothly on the conveyor belt, reducing the transmission interruption caused by material jamming or deviation, and improving the efficiency of the entire conveying system. At the same time, the roller also has a certain buffering performance. When the material encounters impact or vibration during the transmission process, the roller can absorb part of the energy and reduce the direct impact on the material, thereby reducing the risk of material damage.

[0009] Preferably, an elastic rod is fixedly connected to the middle of the side wall of the movable plate; there are multiple elastic rods and they are regularly arranged in a linear array on the side wall of the movable plate; the multiple elastic rods are respectively arranged between a pair of adjacent fixed rods; the ends of the elastic rods are fixedly connected to push plates; the elastic rods and push plates are both made of elastic materials; in this step, by arranging elastic rods and push plates, materials can be pushed from both sides to the middle of the conveyor belt, so that the materials are more evenly distributed on the conveyor belt, avoiding local accumulation or vacancies that reduce the space utilization of the conveyor belt, and improving the transportation capacity and efficiency of the belt conveyor.

[0010] Preferably, a brush is fixedly connected to the middle part of the inner wall of the limit plate; the brushes are in plurality and are regularly arranged in a circular array on the side wall of the limit plate; the brushes slide on the conveyor roller; the brushes are made of elastic material; the brush is arranged in this step to clean the surface of the conveyor roller. The adhesion accumulated on the surface of the conveyor roller for a long time will cause the surface of the conveyor roller to be uneven, which will further cause the conveyor belt to deviate. Therefore, cleaning the surface of the conveyor roller can maintain the flatness of the conveyor roller, prevent the conveyor belt from deviating, and ensure the stability of material conveying. At the same time, cleaning the surface of the conveyor roller can reduce the friction between the material adhered to the surface of the conveyor roller and the conveyor roller, thereby improving the operation efficiency of the belt conveyor.

[0011] Preferably, a connecting plate is fixedly connected to the middle part of the side wall of the limit plate; the connecting plate is arranged between a pair of adjacent limit plates; by setting the connecting plate in this step, multiple synchronously moving limit plates can be tightly connected together to form a more stable overall structure, thereby ensuring the stable operation of the entire correction system.

[0012] Preferably, an oil storage bag is fixedly connected to the middle part of the side wall of the limit plate; the oil storage bag is arranged between the limit plate and the conveyor belt; the oil storage bag is made of elastic material; by arranging the oil storage bag in this step, a lubricating film can be formed between the conveyor roller and the conveyor belt, thereby reducing direct contact and friction between the two, and helping to extend the service life of the conveyor roller and the conveyor belt. At the same time, the lubricating oil can reduce the friction resistance between the conveyor roller and the conveyor belt, so that the belt conveyor can run more smoothly during operation, reduce energy loss, and thus improve the operation efficiency of the entire system.

[0013] Preferably, the detection assembly includes a fixed plate; the fixed plate is fixedly connected to the side wall of the support frame; the fixed plates are a pair and are symmetrically arranged on both sides of the support frame; a level detector is fixedly connected to the middle of the side wall of the fixed plate; in this step, by setting up the level detector, the horizontal state of the conveyor belt can be monitored in real time. Once the conveyor belt deviates, the level detector will immediately display the corresponding deviation value or issue an alarm, which helps the staff to quickly discover and deal with the deviation problem.

[0014] Preferably, a collection box is slidably fitted in the middle of the inner wall of the base; the collection box is arranged under the conveyor belt; by setting the collection box in this step, materials scattered from the edge of the conveyor belt can be collected, thereby reducing material losses and improving production efficiency. After setting the collection box, the workload of cleaning up scattered materials can be greatly reduced, thereby improving work efficiency.

[0015] Preferably, an elastic pad is fixedly connected to the inner wall of the bottom of the collection box; the elastic pad is made of elastic material; this step, by arranging the elastic pad inside the collection box, can cushion the impact force of the material falling into the collection box, reduce the risk of the material being damaged by impact, and thus protect the integrity and quality of the material.

[0016] The beneficial effects of the present invention are as follows: 1. The belt conveyor deviation correction device described in the present invention is provided with a conveyor belt, an electric push rod, a movable plate and a limit plate.

At the same time, it can also reduce the scattering and waste of materials caused by the deviation of the conveyor belt.

[0017] 2. The belt conveyor correction device described in the present invention, by setting a fixed rod and a roller, can make it easier to adjust the position of materials as needed during the transmission process, ensuring that the materials accurately reach the designated position, and the roller can also make the materials move smoothly on the conveyor belt, reducing transmission interruptions caused by material jams or deviations, thereby improving the efficiency of the entire transmission system. At the same time, the roller also has a certain buffering performance. When the material encounters impact or vibration during the transmission process, the roller can absorb part of the energy and reduce the direct impact on the material, thereby reducing the risk of material damage.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Specific examples are given below.

[0023] like Figures 1 to 5 As shown, a belt conveyor deviation correction device described in an embodiment of the present invention comprises a base 1; a support frame 11 is fixedly connected to the top side wall of the base 1; the support frames 11 are a pair and are symmetrically arranged on both sides of the base 1; a motor 12 is provided in the middle of the side wall of one side of the support frame 11; a conveying roller 13 is fixedly connected to the output end of the motor 12; the conveying rollers 13 are multiple and are evenly arranged between the pair of support frames 11; the conveying rollers 13 are rotatably connected to the support frame 11; a conveying belt 14 is rotatably connected between the multiple conveying rollers 13; an electric push rod 15 is fixedly connected to the middle of the side wall of the support frame 11; A movable plate 16 is fixedly connected to the output end of the electric push rod 15; a plurality of limit plates 17 are fixedly connected to the middle of the side wall of the movable plate 16; the limit plates 17 are sleeved on the outside of the conveying roller 13; a detection component is provided above the conveying belt 14; when working, the staff starts the motor 12, the motor 12 drives the connected conveying roller 13 to rotate, and the conveying roller 13 drives the conveying belt 14 to move when it rotates, because the conveying belt 14 connects the plurality of conveying rollers 13 together, and the plurality of conveying rollers 13 rotate synchronously at this time, so that the conveying belt 14 continues to move under the push of the plurality of conveying rollers 13, and then the staff The material to be conveyed is placed on the top of the conveyor belt 14, and the material starts to move under the drive of the conveyor belt 14. When the detection component detects that the position of the conveyor belt 14 is offset, the staff starts the electric push rods 15 on both sides of the support frame 11. At this time, the electric push rods 15 push the movable plate 16 connected to the output end, so that the movable plate 16 simultaneously drives multiple limit plates 17 to approach the conveyor belt 14. At this time, the limit plate 17 will correct the deviated conveyor belt 14. This step sets the conveyor belt 14, the electric push rod 15, the movable plate 16 and the limit plate 17. When the conveyor belt 14 deviates from the predetermined track, the electric push rods 15 are started. The rod 15 is adjusted without human intervention to ensure that the conveyor belt 14 remains on the correct running path, and the correction device driven by the electric push rod 15 can be flexibly adjusted according to the actual deviation of the conveyor belt 14 to adapt to the requirements of different materials and working conditions, ensuring that the conveyor belt 14 always remains in the correct position. By timely correcting the deviation of the conveyor belt 14, the friction between the conveyor belt 14 and the support frame 11 can also be reduced, thereby extending the service life of the conveyor belt 14 and reducing the replacement cost caused by wear and tear. At the same time, it can also reduce the scattering and waste of materials caused by the deviation of the conveyor belt 14.

[0024] like Figures 1 to 5 As shown, a fixed rod 2 is fixedly connected to the middle of the side wall of the movable plate 16; the fixed rods 2 are multiple and are regularly arranged in a linear array on the side wall of the movable plate 16; a roller 21 is rotatably connected to the middle of the side wall of the fixed rod 2; the roller 21 is arranged above the conveyor belt 14; when working, when the electric push rod 15 pushes the movable plate 16 to move, the movable plate 16 will drive the multiple fixed rods 2 on the side wall to move, so that the fixed rod 2 brings the roller 21 close to the conveyor belt 14, so that the material on the top of the conveyor belt 14 contacts with the roller 21, and during the contact process, the roller 21 will contact the conveyor belt 14 by rolling. The position of the material is adjusted. In this step, by setting the fixed rod 2 and the roller 21, the position of the material can be adjusted more easily as needed during the transmission process, ensuring that the material arrives at the specified position accurately. The roller 21 can also make the material move smoothly on the conveyor belt 14, reducing the transmission interruption caused by material jamming or deviation, and improving the efficiency of the entire transmission system. At the same time, the roller 21 also has a certain buffering performance. When the material encounters impact or vibration during the transmission process, the roller 21 can absorb part of the energy and reduce the direct impact on the material, thereby reducing the risk of material damage.

[0025] like Figures 1 to 5 As shown, an elastic rod 3 is fixedly connected to the middle part of the side wall of the movable plate 16; the elastic rod 3 is multiple and is regularly arranged in a linear array on the side wall of the movable plate 16; the multiple elastic rods 3 are respectively arranged between a pair of adjacent fixed rods 2; a push plate 31 is fixedly connected to the end of the elastic rod 3; the elastic rod 3 and the push plate 31 are both made of elastic material; during operation, when the electric push rod 15 pushes the movable plate 16 to move, the movable plate 16 will drive the multiple elastic rods 3 on the side wall to move, so that the elastic rod 3 brings the push plate 31 to approach the conveyor belt 14, and at this time the push plate 31 will slide on the top of the conveyor belt 14 and push the material on the top of the conveyor belt 14, and push the material at the edge of the conveyor belt 14 to the center of the conveyor belt 14. In this step, by setting the elastic rod 3 and the push plate 31, the material can be pushed from both sides to the middle of the conveyor belt 14, so that the material is more evenly distributed on the conveyor belt 14, avoiding the situation where local accumulation or vacancy leads to a reduction in the space utilization rate of the conveyor belt 14, and improving the transportation capacity and efficiency of the belt conveyor.

[0026] like Figure 4 and Figure 5As shown, a brush 4 is fixedly connected to the middle of the inner wall of the limiting plate 17; the brushes 4 are multiple and are regularly arranged in a circular array on the side wall of the limiting plate 17; the brushes 4 slide on the conveying roller 13; the brushes 4 are made of elastic material; when working, because the limiting plate 17 is covered on the outside of the conveying roller 13, when the limiting plate 17 moves, the limiting plate 17 will slide on the conveying roller 13 with the multiple brushes 4 on the inner wall, and at this time, the brushes 4 will clean the materials adhered to the surface of the conveying roller 13, such as coal dust, mud, oil stains, etc. Cleaning: In this step, the brush 4 is arranged to clean the surface of the conveyor roller 13. The adhesion accumulated on the surface of the conveyor roller 13 for a long time will cause the surface of the conveyor roller 13 to be uneven, which will further cause the conveyor belt 14 to deviate. Therefore, cleaning the surface of the conveyor roller 13 can maintain the flatness of the conveyor roller 13, prevent the conveyor belt 14 from deviating, and ensure the stability of material transportation. At the same time, cleaning the surface of the conveyor roller 13 can reduce the friction between the material adhered to the surface of the conveyor roller 13 and the conveyor roller 13, thereby improving the operation efficiency of the belt conveyor.

[0027] like Figure 4 and Figure 5 As shown, a connecting plate 5 is fixedly connected to the middle part of the side wall of the limit plate 17; the connecting plate 5 is arranged between a pair of adjacent limit plates 17; during operation, when multiple limit plates 17 move, the connecting plates 5 connected between adjacent limit plates 17 will move synchronously to ensure that the limit plates 17 move at the same level. In this step, by setting the connecting plate 5, multiple synchronously moving limit plates 17 can be tightly connected together to form a more stable overall structure, thereby ensuring the stable operation of the entire correction system.

[0028] like Figure 4 and Figure 5 As shown, an oil storage bag 6 is fixedly connected to the middle part of the side wall of the limit plate 17; the oil storage bag 6 is arranged between the limit plate 17 and the conveyor belt 14; the oil storage bag 6 is made of elastic material; during operation, when the limit plate 17 moves toward the conveyor belt 14 and contacts with the conveyor belt 14, the conveyor belt 14 will squeeze the oil storage bag 6 on the surface of the limit plate 17, and the lubricating fluid inside the oil storage bag 6 will overflow outward and be smeared between the conveyor roller 13 and the conveyor belt 14. In this step, by setting the oil storage bag 6, a lubricating film can be formed between the conveyor roller 13 and the conveyor belt 14, reducing direct contact and friction between the two, and helping to extend the service life of the conveyor roller 13 and the conveyor belt 14. At the same time, the lubricating oil can reduce the friction resistance between the conveyor roller 13 and the conveyor belt 14, so that the belt conveyor can be smoother during operation, reduce energy loss, and thus improve the operation efficiency of the entire system.

[0029] like Figures 1 to 3As shown, the detection component includes a fixed plate 7; the fixed plate 7 is fixedly connected to the side wall of the support frame 11; the fixed plates 7 are a pair and are symmetrically arranged on both sides of the support frame 11; a level detector 71 is fixedly connected to the middle of the side wall of the fixed plate 7; when working, the staff determines whether the position of the conveyor belt 14 is offset according to the offset indication of the level detector 71. When it is found that the conveyor belt 14 is offset, the electric push rod 15 is started to correct the deviation. In this step, by setting the level detector 71, the horizontal state of the conveyor belt 14 can be monitored in real time. Once the conveyor belt 14 is offset, the level detector 71 will immediately display the corresponding deviation value or issue an alarm, which is helpful for the staff to quickly find and deal with the offset problem.

[0030] like Figure 1 and Figure 2 As shown, a collecting box 8 is slidably fitted in the middle of the inner wall of the base 1; the collecting box 8 is arranged under the conveyor belt 14; during operation, when materials fall from the top of the conveyor belt 14 during the conveying process, they will directly fall into the collecting box 8, and the staff can pull the collecting box 8 out of the base 1 to clean up the fallen materials. In this step, by setting up the collecting box 8, the materials scattered from the edge of the conveyor belt 14 can be collected, thereby reducing material losses and improving production efficiency. After setting up the collecting box 8, the workload of cleaning up the scattered materials can be greatly reduced, thereby improving work efficiency.

[0031] like Figure 1 and Figure 2 As shown, an elastic pad 9 is fixedly connected to the inner wall of the bottom of the collecting box 8; the elastic pad 9 is made of elastic material; in this step, by arranging the elastic pad 9 inside the collecting box 8, the impact force of the material falling into the collecting box 8 can be cushioned, and the risk of the material being damaged due to impact can be reduced, thereby protecting the integrity and quality of the material.

[0032] Working principle: The staff starts the motor 12, and the motor 12 drives the connected conveyor roller 13 to rotate. When the conveyor roller 13 rotates, it drives the conveyor belt 14 to move. Because the conveyor belt 14 connects multiple conveyor rollers 13 together, the multiple conveyor rollers 13 rotate synchronously at this time, so that the conveyor belt 14 continues to move under the push of the multiple conveyor rollers 13. Then the staff places the material to be conveyed on the top of the conveyor belt 14, and the material starts to move under the drive of the conveyor belt 14. When the detection component detects that the position of the conveyor belt 14 is offset, the staff starts the electric push rods 15 on both sides of the support frame 11. At this time, the electric push rods 15 push the output end connection The movable plate 16 drives the plurality of limit plates 17 to approach the conveyor belt 14 at the same time. At this time, the limit plates 17 will correct the deviated conveyor belt 14. When the electric push rod 15 pushes the movable plate 16 to move, the movable plate 16 will drive the plurality of fixed rods 2 on the side wall to move, so that the fixed rod 2 brings the roller 21 close to the conveyor belt 14, so that the material on the top of the conveyor belt 14 contacts the roller 21. During the contact process, the roller 21 will adjust the position of the material by rolling. When the electric push rod 15 pushes the movable plate 16 to move, the movable plate 16 will drive the plurality of elastic rods 3 on the side wall to move, so that the elastic rods 3 The rod 3 brings the push plate 31 closer to the conveyor belt 14. At this time, the push plate 31 will slide on the top of the conveyor belt 14 and push the material on the top of the conveyor belt 14, pushing the material at the edge of the conveyor belt 14 to the center of the conveyor belt 14. Because the limit plate 17 is covered on the outside of the conveyor roller 13, when the limit plate 17 moves, the limit plate 17 will slide on the conveyor roller 13 with multiple brushes 4 on the inner wall. At this time, the brush 4 will clean the materials adhered to the surface of the conveyor roller 13, such as coal dust, mud, oil, etc. When multiple limit plates 17 move, the connecting plates 5 connected between adjacent limit plates 17 will move synchronously to ensure that the limit plates 17 are on the same level. When the limit plate 17 moves toward the conveyor belt 14 and contacts the conveyor belt 14, the conveyor belt 14 will squeeze the oil storage bag 6 on the surface of the limit plate 17. At this time, the lubricating fluid inside the oil storage bag 6 will overflow and be smeared between the conveyor roller 13 and the conveyor belt 14. The staff determines whether the position of the conveyor belt 14 is offset according to the offset indication of the level detector 71. When it is found that the conveyor belt 14 is offset, the electric push rod 15 is started to correct it. When the material falls from the top of the conveyor belt 14 during the transmission process, it will fall directly into the collection box 8. The staff can pull the collection box 8 out of the base 1 to clean up the fallen material.
