Description

Technical Field

[0001] This invention relates to the field of conveyor alignment, and in particular to an automatic alignment device for belt conveyors. Background Technology

[0002] As a core piece of equipment in the continuous conveying field, belt conveyors have become deeply integrated into key industrial scenarios such as mining, port loading and unloading, building materials production, and power coal transportation, thanks to their advantages of large conveying capacity, high efficiency, and wide applicability. They have become the "lifeline" of material transfer. In underground coal conveying systems in mines, a single belt conveyor can transport distances exceeding one kilometer and a daily conveying capacity of tens of thousands of tons, directly determining the mine's raw coal production efficiency. In port bulk cargo terminals, belt conveyors undertake the unloading and transfer of bulk commodities such as iron ore and coal, and their operational stability directly affects ship turnaround efficiency and port throughput. In cement and building materials production lines, belt conveyors need to continuously transport abrasive materials such as sand, gravel, and cement clinker, operating under harsh conditions of high load and high dust levels for extended periods, making them a critical node for ensuring the continuous operation of the production line.

[0003] If conveyor belt misalignment is not corrected in time, it will trigger a series of chain reactions, causing equipment damage, production interruption, and even safety accidents. From the perspective of equipment damage, the edge of the misaligned conveyor belt will continuously rub against the frame, guard plates, and other equipment components, causing wear and cracking of the conveyor belt edge rubber layer. In severe cases, it will tear the core layer of the conveyor belt, shortening its service life. The normal service life of an ordinary nylon core conveyor belt is about 3-5 years. If it is in a state of misalignment and friction for a long time, its service life can be shortened to 1-2 years. Moreover, replacing a long-distance conveyor belt requires an investment of hundreds of thousands of yuan and several days of downtime, resulting in significant economic losses.

[0004] Currently, most automatic belt conveyor alignment devices on the market rely on a single elastic reset structure, such as using springs to apply a reset force to the misaligned conveyor wheel to achieve position correction. However, in actual working conditions, this type of device has significant shortcomings: when the conveyor is transporting heavy materials such as coal and ore, if there is a sudden accumulation of material, sudden damage to the conveyor belt joint, or equipment start-up impact, it will generate a severe lateral impact load on the conveyor wheel. At this time, the response speed of a single elastic structure is difficult to match the changes in instantaneous impact and cannot quickly suppress the large swing of the conveyor wheel, resulting in excessive misalignment between the conveyor wheel and the device's central axis. This can lead to structural damage such as cracking of the device's weld points and deformation of the fixing pins, and even cause the conveyor wheel to break. This not only affects the normal operation of the equipment but also increases maintenance costs and safety hazards. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that the response speed of a single elastic structure is difficult to match the changes of instantaneous impact.

[0006] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes an automatic belt conveyor alignment device, which includes a conveyor wheel; a disturbance part located inside the conveyor wheel and movably connected to the conveyor wheel; a swing part located on the inner wall of the conveyor wheel; and a locking part located inside the swing part and coaxially arranged with the swing part; wherein, when the conveyor wheel speed reaches a threshold, the conveyor wheel drives the swing part to contact and lock with the locking part.

[0007] In a preferred embodiment of the automatic belt conveyor alignment device of the present invention: the disturbance part includes a disturbance ring that overlaps with the central axis of the conveyor wheel, and the outer periphery of the disturbance ring is connected to the conveyor wheel through a plurality of disturbance elements.

[0008] In a preferred embodiment of the automatic belt conveyor alignment device of the present invention: a balancing part is provided between the disturbance part and the locking part, and a shaft is provided in the middle of the balancing part, the shaft passing through the disturbance part and the locking part in sequence.

[0009] In a preferred embodiment of the automatic belt conveyor alignment device of the present invention: the balancing part includes an inner fixed seat fixedly sleeved on the shaft, an outer fixed seat coaxially sleeved on the outside of the inner fixed seat, and a plurality of symmetrically distributed elastic alignment components connected between the inner fixed seat and the outer fixed seat.

[0010] In a preferred embodiment of the automatic belt conveyor alignment device of the present invention: the swing part includes a swing ring connected to the inner wall of the conveyor wheel, and a plurality of locking rods are distributed circumferentially on the swing ring. The locking rods are rotatably connected to the swing ring through a connecting ring, and torque members with opposite torques are provided on both sides of the connecting ring.

[0011] In a preferred embodiment of the automatic alignment device for belt conveyors of the present invention: the locking part includes a locking disc disposed on the shaft, a plurality of locking blocks corresponding to the locking rod are disposed on the outer side of the locking disc, and a buffer groove is provided on the locking disc to accommodate the sliding of the locking disc, and the buffer groove is provided with a buffer member that applies damping to the locking blocks.

[0012] In a preferred embodiment of the automatic belt conveyor alignment device of the present invention: a counterweight is fixed on the locking end of the locking rod, and the locking block has a locking hole that locks with the locking rod.

[0013] In a preferred embodiment of the automatic belt conveyor alignment device of the present invention, a cleaning unit is further included. The cleaning unit includes a storage ring located on one side of the locking disc and fixed on the shaft. The storage ring has multiple storage slots inside, and a cleaning medium is added inside the storage slots. The locking disc has multiple cleaning holes communicating with the storage slots at positions corresponding to the locking blocks. A deformation layer is fixed inside the cleaning holes.

[0014] In a preferred embodiment of the automatic belt conveyor alignment device of the present invention: a piston block is slidably provided inside the storage tank, a connector is fixed at one end of the piston block, and the end of the connector away from the piston block moves through the storage ring and connects to the inner wall of the conveyor wheel.

[0015] In a preferred embodiment of the automatic belt conveyor alignment device of the present invention: the connecting member includes an upper connecting rod and a lower connecting rod, the upper connecting rod and the lower connecting rod are connected by a ball shaft, the lower connecting rod is slidably and sealed to the storage tank, and the upper connecting rod is bonded and fixed to the conveyor wheel.

[0016] The beneficial effects of this invention are as follows: by automatically locking and fixing the locking rod and the locking block, the relative movement between the conveying wheel and the shaft is restricted, avoiding structural damage such as cracking of the welding point and deformation of the intermediate fixing pin caused by excessive offset of the central axis of the conveying wheel and the shaft, while preventing the conveying wheel from jamming or breaking, thus eliminating safety hazards. The damping force generated by the buffer when the locking block slides can slow down the sliding speed of the locking block, prevent the locking block from colliding violently with the inner wall of the buffer groove, protect the locking block and locking disc, and extend the service life of the components.

[0017] By setting up a cleaning unit, the cleaning medium can be automatically driven to clean the locking block when the conveyor wheel swings, effectively removing pollutants such as coal dust, mine dust, and water vapor attached to the locking block. This prevents the locking block from failing to trigger the locking rod due to pollutants, ensuring that the locking unit can always play a normal protective role. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0022] Reference Figure 1 This embodiment provides an automatic belt conveyor alignment device, including a conveyor wheel 1; a disturbance part 2, which is located inside the conveyor wheel 1 and movably connected to the conveyor wheel 1; a swing part 3, which is located on the inner wall of the conveyor wheel 1; and a locking part 4, which is located inside the swing part 3 and coaxially arranged with the swing part 3; wherein, when the rotational speed of the conveyor wheel 1 reaches a threshold, the conveyor wheel 1 drives the swing part 3 to contact and lock with the locking part 4.

[0023] In this embodiment, the disturbance part 2 is located inside the conveyor wheel 1 and is movably connected to the conveyor wheel 1. This movable connection allows the disturbance part 2 to swing or rotate within a certain range inside the conveyor wheel 1.

[0024] The swing part 3 is installed on the inner wall of the conveyor wheel 1. The installation position of the swing part 3 must ensure that it can swing on the inner wall of the conveyor wheel 1. For example, the swing part 3 can be connected to the inner wall of the conveyor wheel 1 through a hinge structure.

[0025] The locking part 4 is located inside the swing part 3 and is coaxial with the swing part 3. Coaxial setting means that the central axis of the locking part 4 coincides with the central axis of the swing part 3. This coaxial setting can ensure that the locking part 4 and the swing part 3 maintain synchronous center positioning during movement, and avoid the locking function failure due to axis offset.

[0026] When the belt conveyor starts running, the conveyor wheel 1 rotates accordingly. As the running time of the conveyor wheel 1 increases or the load changes, the speed of the conveyor wheel 1 will gradually change. When the speed of the conveyor wheel 1 increases and reaches the preset threshold, the motion state of the conveyor wheel 1 will generate enough driving force to drive the swing part 3 to move, so that the swing part 3 starts to swing around its installation point. During the swing of the swing part 3, since the locking part 4 is located inside the swing part 3 and is coaxial with the swing part 3, when the swing part 3 swings to a specific position, the locking part 4 will contact a specific structure inside the swing part 3, thereby realizing the locking function. After locking, the swing part 3 is fixed in the current position, and then the swing part 3 generates a reverse force on the conveyor wheel 1, so that the conveyor wheel 1, which may have a large deviation, is effectively limited, and the automatic deviation adjustment function is realized.

[0027] refer to Figure 1-2As an optional embodiment, the disturbance part 2 includes a disturbance ring 21 that overlaps with the central axis of the conveyor wheel 1. The outer periphery of the disturbance ring 21 is connected to the conveyor wheel 1 through multiple disturbance elements 22. A balancing part 5 is provided between the disturbance part 2 and the locking part 4. A shaft 51 is provided in the middle of the balancing part 5, and the shaft 51 passes through the disturbance part 2 and the locking part 4 in sequence. The balancing part 5 includes an inner fixing seat 52 fixedly sleeved on the shaft 51. An outer fixing seat 53 is coaxially sleeved on the outer side of the inner fixing seat 52. Multiple symmetrically distributed elastic adjustment elements 54 are connected between the inner fixing seat 52 and the outer fixing seat 53.

[0028] In this embodiment, the disturbance part 2 includes a disturbance ring 21 that overlaps with the central axis of the conveyor wheel 1. The outer periphery of the disturbance ring 21 is connected to the conveyor wheel 1 through multiple disturbance components 22. When the conveyor wheel 1 encounters extreme impact loads or instantaneous large offset conditions, the conveyor wheel 1 can swing around the disturbance ring 21 because the disturbance ring 21 overlaps with the central axis of the conveyor wheel 1 and is connected through multiple disturbance components 22. This swinging method can effectively disperse the force of extreme impact loads on the conveyor wheel 1 and the entire conveying system, avoiding damage to components due to excessive load concentration. At the same time, under instantaneous large offset conditions, the position of the conveyor wheel 1 is adjusted by swinging, reducing the impact of offset on the conveying process. When the conveyor wheel 1 deviates from its designated path, a misalignment occurs between the central axis of the conveyor wheel 1 and the central axis of the shaft 51, causing the conveyor wheel 1 to oscillate. This oscillation of the conveyor wheel 1 affects the elastic adjustment components 54 in the balancing section 5, specifically by compressing and stretching the elastic adjustment components 54 at different positions. Because the elastic adjustment components 54 are elastic, they generate a restoring force after being compressed and stretched. To restore the conveyor wheel 1 to a stable state, under the action of this restoring force, the conveyor wheel 1 needs to oscillate in the opposite direction of the deviation to reset, thereby restoring the balance state where the central axis of the conveyor wheel 1 coincides with the central axis of the shaft 51. This process achieves automatic deviation adjustment. Furthermore, because multiple symmetrically distributed elastic adjustment components 54 are arranged in the balancing section 5, the combined restoring force generated by these multiple components significantly enhances the adjustment force on the conveyor wheel 1, thereby greatly improving the adjustment effect. This allows for faster and more effective correction of the conveyor wheel 1's deviation, ensuring its continuous and stable operation. The disturbance ring 21 is ring-shaped, and its central axis completely overlaps with the central axis of the conveyor wheel 1. It is installed inside the conveyor wheel 1 and coincides with the central axis of the conveyor wheel 1. The disturbance component 22 may specifically include metal rods, ball shafts 653, etc., and there may be multiple of them. The shaft 51 is a cylindrical long rod, which is installed in the middle of the balancing part 5 and passes through the disturbance part 2 and the locking part 4 in sequence, thus providing support and positioning for the disturbance part 2 and the locking part 4. The inner fixing seat 52 is fixedly sleeved on the shaft 51, and the inner fixing seat 52 is either interference-fitted or connected to the shaft 51 by a key, ensuring that the inner fixing seat 52 and the shaft 51 rotate synchronously and will not slide relative to each other. The outer fixing seat 53 has an inner diameter larger than the outer diameter of the inner fixing seat 52, and is coaxially sleeved on the outside of the inner fixing seat 52, maintaining coaxiality with the inner fixing seat 52. The elastic adjustment component 54 may include a helical spring, a disc spring, a rubber elastic component, etc., and there are multiple such components. The connection method is that one end is fixedly connected to the outer peripheral surface of the inner fixing seat 52 (such as welding, hook connection, etc.), and the other end is fixedly connected to the inner peripheral surface of the outer fixing seat 53. The multiple elastic adjustment components 54 are symmetrically distributed between the inner fixing seat 52 and the outer fixing seat 53 (such as evenly symmetrically distributed along the circumference). By designing the disturbance ring 21 and multiple disturbance components 22 of the disturbance part 2, the conveyor wheel 1 can swing around the disturbance ring 21 when encountering extreme impact loads or instantaneous large offset conditions, thereby dispersing the impact load and reducing the impact of offset. By utilizing the shaft 51, inner fixed seat 52, outer fixed seat 53, and multiple symmetrically distributed elastic adjustment components 54 of the balance part 5, when the conveyor wheel 1 deviates, the elastic adjustment components 54 are squeezed and stretched to generate a restoring force, which drives the conveyor wheel 1 to swing back and reset, thereby achieving automatic deviation adjustment. refer to Figure 2-5 In one embodiment provided in this application, the swinging part 3 includes a swinging ring 31 connected to the inner wall of the conveying wheel 1. Multiple locking rods 32 are circumferentially distributed on the swinging ring 31. The locking rods 32 are rotatably connected to the swinging ring 31 via a connecting ring. Torque members 33 with opposite torques are provided on both sides of the connecting ring. The locking part 4 includes a locking disc 41 mounted on the shaft 51. Multiple locking blocks 42 corresponding to the locking rods 32 are provided on the outer side of the locking disc 41. A buffer groove 43 is provided on the locking disc 41 to accommodate the sliding of the locking disc 41. The buffer groove 43 is provided with a buffer member 44 that applies damping to the locking blocks 42. A counterweight 321 is fixed to the locking end of the locking rod 32. The locking block 42 has a locking hole 322 for locking with the locking rod 32.

[0029] In this embodiment, under extreme impact loads or instantaneous large deviation conditions, when the conveyor belt experiences severe instantaneous deviation due to material accumulation (such as a large amount of coal accumulating in a certain section of the conveyor belt when conveying coal), joint damage (such as the canvas layer breaking at the conveyor belt joint), or starting impact, the conveyor wheel 1 will be subjected to a great lateral impact force. At this time, although the elastic adjustment component 54 can provide elasticity, its response speed may not be sufficient to immediately suppress excessive swaying, resulting in excessive deviation between the conveyor wheel 1 and the central axis of the shaft 51, exceeding the allowable range of the limit groove, causing structural damage (such as cracking of the weld point, deformation of the intermediate fixing pin), or even causing the conveyor wheel 1 to jam or break, forming a safety hazard. When the conveyor belt experiences a severe, momentary deviation, it causes a sudden increase in the oscillation speed of the conveyor wheel 1, resulting in a high-angular acceleration. Since a counterweight 321 is fixed to the locking end of the locking rod 32, this high-angular acceleration generates a significant inertial torque. This inertial torque overcomes the torque generated by the opposing torque members 33 on both sides of the connecting ring, driving the locking rod 32 to oscillate around the connection point of the connecting ring. During the oscillation of the locking rod 32, its locking end approaches the locking point on the outer side of the locking disc 41. Block 42 eventually contacts and engages with the locking hole 322 on the locking block 42, achieving automatic locking and fixing; after locking and fixing, the relative movement of the conveying wheel 1 and the shaft 51 is restricted, the conveying wheel 1 cannot continue to swing significantly, and the offset between the central axis of the conveying wheel 1 and the shaft 51 is forcibly fixed at the current angle, thereby avoiding structural damage caused by excessive offset; at the same time, because the locking occurs at the moment of high impact, the kinetic energy generated will be absorbed by the mechanical locking structure composed of the swing part 3 and the locking part 4, playing a buffering and protective role. The locking rod 32 is long and rod-shaped. One end has a protrusion or groove that matches the locking hole 322, and the other end is rotatably connected to the swing ring 31 through a connecting ring. A counterweight 321 is fixed on the locking end of the locking rod 32 by welding or bolt connection. Torque component 33 can specifically be a torsion spring, torsion bar, elastic metal sheet, etc. The buffer component 44 can specifically be a damping spring, a rubber damping block (attached to the inner wall of the buffer groove 43), etc. By automatically locking and fixing the locking rod 32 and the locking block 42, the relative movement between the conveyor wheel 1 and the shaft 51 is restricted, avoiding structural damage such as cracking of the welding point and deformation of the intermediate fixing pin caused by excessive offset of the central axis of the conveyor wheel 1 and the shaft 51. At the same time, it prevents the conveyor wheel 1 from jamming or breaking, eliminating safety hazards. When the locking block 42 slides, the damping force generated by the buffer 44 can slow down the sliding speed of the locking block 42, prevent the locking block 42 from violently colliding with the inner wall of the buffer groove 43, protect the locking block 42 and the locking disc 41, and extend the service life of the components. refer to Figure 6In some embodiments, a cleaning unit 6 is also included. The cleaning unit 6 includes a storage ring 61 located on one side of the locking disc 41 and fixed to the shaft 51. The storage ring 61 has multiple storage slots 62 inside, and cleaning media is added to the storage slots 62. The locking disc 41 has multiple cleaning holes 63 corresponding to the positions of the locking block 42, which communicate with the storage slots 62. A deformation layer is fixed inside the cleaning holes 63. A piston block 64 is slidably disposed inside the storage slot 62. A connector 65 is fixed to one end of the piston block 64. The end of the connector 65 away from the piston block 64 movably passes through the storage ring 61 and is connected to the inner wall of the conveyor wheel 1. The connector 65 includes an upper connecting rod 651 and a lower connecting rod 652. The upper connecting rod 651 and the lower connecting rod 652 are connected by a ball joint 653. The lower connecting rod 652 is slidably and sealed to the storage slot 62, and the upper connecting rod 651 is bonded and fixed to the conveyor wheel 1.

[0030] In this embodiment, during the long-term operation of the conveyor belt, pollutants such as coal dust, mine dust, and water vapor may seep into the locking part 4. These pollutants will adhere to the locking block 42, causing the locking block 42 to be unable to trigger the locking action with the locking rod 32, thus causing the locking part 4 to lose its protective function for the conveyor wheel 1. When the conveyor wheel 1 swings, since the upper connecting rod 651 is fixed to the conveyor wheel 1, the conveyor wheel 1 will pull the upper connecting rod 651. The upper connecting rod 651 drives the lower connecting rod 652 to move through the ball shaft 653. The lower connecting rod 652 is fixedly connected to the piston block 64 and is also sealed and slidably connected to the storage tank 62. Therefore, the lower connecting rod 652 will drive the piston block 64 to slide in the storage tank 62. During the sliding process, the piston block 64 will squeeze the cleaning medium in the storage tank 62. The squeezed cleaning medium will flow towards the cleaning hole 63. When the pressure of the cleaning medium reaches a predetermined value, it will act on the cleaning hole 63. The deformation layer inside 3 deforms and opens, allowing the cleaning medium to be discharged from the cleaning hole 63 with a stronger impact force. The discharged cleaning medium acts on the locking block 42, thereby cleaning the coal powder, mine dust and other pollutants attached to the locking block 42. During the swing of the conveyor wheel 1, since the upper connecting rod 651 and the lower connecting rod 652 are connected by the ball shaft 653, the ball shaft 653 can rotate at multiple angles. Therefore, the connecting part 65 can adapt well to the swing of the conveyor wheel 1 in different directions and amplitudes, ensuring that the piston block 64 can be driven to squeeze the cleaning medium and complete the cleaning action in any swing state of the conveyor wheel 1. The deformation trigger pressure of the deformation layer can be set according to the cleaning requirements. This ensures that the cleaning medium has sufficient impact force while avoiding excessively low pressure that could cause the deformation layer to open accidentally, resulting in waste of the cleaning medium. The cleaning unit 6 automatically drives the cleaning medium to clean the locking block 42 when the conveyor wheel 1 swings, effectively removing contaminants such as coal dust, mine dust, and water vapor adhering to the locking block 42. This prevents contaminants from preventing the locking block 42 from triggering the locking rod 32, ensuring that the locking unit 4 always functions properly for protection. The connector 65 adopts a combination structure of upper connecting rod 651, lower connecting rod 652 and ball shaft 653, which can adapt well to the swing of the conveyor wheel 1 and ensure that the piston block 64 can be stably driven to squeeze the cleaning medium under different swing states of the conveyor wheel 1, thus ensuring the reliability and continuity of the cleaning action. Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
