Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a fully automatic bidirectional self-aligning idler group correction device. Background Technology

[0002] Belt conveyors are widely used material conveying equipment in the industrial field, undertaking transportation tasks in many scenarios such as mines, ports, and metallurgy. They use a drive unit to drive a belt to move, thereby realizing the transport of goods. However, during long-term operation, belt conveyors may experience belt misalignment due to various factors such as the stability of the installation foundation, changes in equipment load, and the impact of falling materials.

[0003] In the prior art, various belt misalignment correction devices have been developed to address the problem of belt conveyor misalignment. For example, Chinese utility model patent CN222117968U discloses a hydraulic heavy-duty belt conveyor misalignment correction device. This device mainly includes a vertically mounted upright frame with a shaped plate fixed to its upper end. A misalignment sensor is installed on one side of the shaped plate, and the upright frame and the shaped plate, as well as the shaped plate and the misalignment sensor, are rigidly connected. When the belt misaligns, the edge of the belt contacts the misalignment sensor, which detects the misalignment signal and triggers subsequent correction actions. Its working principle is to use the direct contact of the rigid structure to sense the belt deviation, and then use a hydraulic system to drive the correction mechanism to adjust the belt. This structure can achieve belt misalignment detection and correction to a certain extent.

[0004] However, the rigid connection method of the belt misalignment sensor in the aforementioned existing technology has significant drawbacks. When the belt misaligns and impacts the misalignment sensor, the edge of the belt will be subjected to large impact stress, which can easily lead to rubber cracking, exposed steel wire rope, and even safety accidents such as belt tearing. At the same time, the rigid mounting position of the misalignment sensor is prone to plastic deformation under long-term impact load, resulting in a decrease in detection accuracy, requiring frequent maintenance, and increasing the maintenance cost of the equipment. Utility Model Content

[0005] This application provides a fully automatic bidirectional self-aligning idler group correction device, which solves the technical problems of easy wear and high maintenance costs after belt misalignment in the prior art, reduces safety hazards during belt conveyor operation, and lowers maintenance costs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fully automatic bidirectional self-aligning idler roller group correction device, including an idler roller assembly and a support mechanism located below the idler roller assembly. Both sides of the support mechanism are fixed with detection and drive brackets. A swing pin and a vertical plate are rotatably installed on the top of the detection and drive brackets. A correction oil pump is installed on one side of the vertical plate, and a correction detection wheel is installed above the correction oil pump. A horizontal plate is fixed on the opposite side of the vertical plate. The horizontal plate has a strip hole. The length direction of the strip hole is perpendicular to the movement direction of the belt. A spring is fitted on the outside of the swing pin. The spring is located below the strip hole. The upper end of the swing pin passes through the strip hole on the horizontal plate and is fitted with a nut. The width of the opposite sides of the nut is greater than the groove width of the strip hole.

[0007] When the belt deviates and impacts the alignment detection wheel, the vertical plate moves laterally under force, causing the swing pin to slide within the slot in the horizontal plate. Simultaneously, this compresses the spring nested around the swing pin. The spring absorbs the impact energy through elastic deformation, causing the alignment detection wheel to swing, preventing a rigid collision between the belt and the detection wheel. When the belt deviation decreases or the impact disappears, the spring force pushes the horizontal plate back to its original position, returning the alignment detection wheel to its initial position, preparing for the next alignment trigger. Throughout this process, the swing pin acts as a hinge fulcrum, working in conjunction with the spring force to achieve elastic mounting of the alignment detection wheel. This avoids rigid impact between the alignment detection wheel and the belt edge, reducing the likelihood of belt wear and safety hazards, and lowering maintenance costs.

[0008] As a further improvement to the above scheme, the support mechanism includes a crossbeam I and a crossbeam II. A longitudinal beam connects the crossbeam I and the crossbeam II. A hydraulic cylinder is installed on the longitudinal beam. The cylinder body of the hydraulic cylinder is hinged to one side of the longitudinal beam. The piston rod of the hydraulic cylinder is rotatably connected to a traction plate. The traction plate is fixed to one side of the idler roller assembly. The bottom of the idler roller assembly is rotatably installed above the crossbeam I. Thus, the driving force of the hydraulic cylinder can directly act on the idler roller assembly.

[0009] As a further improvement to the above solution, the idler assembly includes a horizontal frame, which is mounted on a crossbeam I via a pivot at its bottom center. A horizontal idler is mounted on the horizontal frame, and side frames are fixed at both ends of the horizontal frame, with side idlers mounted on the side frames.

[0010] As a further improvement to the above scheme, a bearing housing is fixed in the middle of the crossbeam I, and a bearing is installed in the bearing housing. The bearing is engaged with the rotating shaft below the horizontal frame. Through the engagement of the bearing housing and the bearing, the resistance of the horizontal swing of the idler roller assembly can be reduced.

[0011] As a further improvement to the above scheme, rollers are installed at both ends of the bottom of the horizontal frame, and a support plate is supported under each roller. The support plate is fixed to the crossbeam I. In this way, the resistance encountered by the roller assembly during the swing process can be further reduced by the contact between the support plate and the roller, and the sensitivity of the correction response can be improved. The symmetrically arranged support plates form a double-support rolling support, which can improve the stability of the equipment.

[0012] As a further improvement to the above solution, the inspection and drive bracket includes a column, the lower end of which is fixed to the support mechanism, and a channel steel is fixed to the upper end of the column. The web of the channel steel is welded to the column, and the groove of the channel steel faces upward. The channel steel with the groove facing upward forms a "groove" structure with an opening at the top, which can provide a position for the installation of the swing pin and the vertical plate.

[0013] As a further improvement to the above scheme, there are two strip holes on the horizontal plate, and a swing pin passes through each of the two strip holes. The lower ends of the two swing pins are rotatably connected to the two flanges of the channel steel, respectively. Thus, when the vertical plate swings due to the impact of the belt, the two swing pins slide synchronously in the strip holes of the horizontal plate, which can evenly bear the lateral force and avoid the vertical plate from tilting or twisting due to the single swing pin being subjected to force on one side.

[0014] As a further improvement to the above scheme, the correction oil pump is installed at the top of the vertical plate, and a sleeve is provided at the lower end of the vertical plate. A pin passes through the sleeve, and the two ends of the pin are connected to the two flanges of the channel steel respectively. The vertical plate can only swing around the axis of the pin in a plane perpendicular to the direction of belt running, which restricts the degree of freedom in other directions.

[0015] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages:

[0016] 1. When the belt deviates and impacts the correction detection wheel, the vertical plate moves laterally under force, causing the swing pin to slide within the slot in the horizontal plate. Simultaneously, the spring nested around the swing pin compresses the spring. The spring absorbs the impact energy through elastic deformation, causing the correction detection wheel to swing, preventing a rigid collision between the belt and the detection wheel. When the belt deviation decreases or the impact disappears, the spring force pushes the horizontal plate back to its original position, returning the correction detection wheel to its initial position, preparing for the next correction trigger. Throughout this process, the swing pin acts as a hinge fulcrum, working in conjunction with the spring force to achieve elastic mounting of the correction detection wheel. This avoids rigid impact between the correction detection wheel and the belt edge, reducing the likelihood of belt wear and safety hazards, and lowering maintenance costs.

[0017] 2. Because a support plate is fixed on beam I, and the support plate cooperates with two rollers at the bottom of the horizontal frame, the resistance encountered by the roller assembly during swing is reduced, and the sensitivity of the correction response is improved. At the same time, the rollers are installed at both ends of the bottom of the horizontal frame, thus forming a double-support rolling support, thereby improving the stability of the equipment.

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0024] This utility model discloses a fully automatic bidirectional self-aligning idler roller group correction device. Please refer to [link / reference]. Figures 1 to 3It includes a roller assembly 1 and a support mechanism 2 located below the roller assembly 1. Both sides of the support mechanism 2 are fixed with inspection and drive brackets 3. A swing pin 4 and a vertical plate 5 are rotatably installed on the top of the inspection and drive brackets 3. A correction oil pump 6 is installed on one side of the vertical plate 5. A correction detection wheel 7 is installed above the correction oil pump 6. A horizontal plate 8 is fixed on the opposite side of the vertical plate 5. A strip hole 801 is provided on the horizontal plate 8. The length direction of the strip hole 801 is perpendicular to the direction of belt movement. A spring 9 is fitted on the outside of the swing pin 4. The spring 9 is located below the strip hole 801. The upper end of the swing pin 4 passes through the strip hole 801 on the horizontal plate 8 and is fitted with a nut 10. The width of the opposite sides of the nut 10 is greater than the groove width of the strip hole 801.

[0025] In this embodiment, as Figure 1 As shown, the support mechanism 2 is arranged horizontally, and the inspection and drive bracket 3 is welded and fixed to both sides of the support mechanism 2, symmetrically distributed. The lower end of the vertical plate 5 is hinged to the inspection and drive bracket 3. The correction oil pump 6 is installed on the plate surface of the vertical plate 5 facing the belt, and the correction detection wheel 7 is installed above the correction oil pump 6. An oil storage box can be installed below the correction oil pump 6, and the oil storage box is connected to the oil pipe (this is prior art and will not be described in detail in this embodiment). The horizontal plate 8 is fixed to the plate surface of the vertical plate 5 facing away from the belt. Its function is to support the spring 9 and cooperate with the swing pin. The radial dimension of the swing pin 4 is smaller than the groove width of the strip hole 801. The lower end of the swing pin 4 is rotatably connected to the inspection and drive bracket 3, and the upper end is provided with an external thread. After the external thread cooperates with the nut 10, the nut 10 can form a limit. The spring 9 is sleeved on the outside of the swing pin 4, located between the horizontal plate 8 and the inspection and drive bracket 3, and the spring 9 is in a compressed state.

[0026] When the belt is running normally, the belt alignment detection wheel 7 is in its initial position. When the belt deviates, the wheel surface of the belt alignment detection wheel 7 contacts the side of the belt. When the belt deviation increases, the belt alignment detection wheel 7 is impacted, and the vertical plate 5 swings to the deviation side, causing the swing pin 4 to slide within the slot 801 and compress the spring 9. The spring 9 absorbs the impact energy through elastic deformation, avoiding rigid collision. When the belt deviation decreases or the impact disappears, the elastic force of the spring 9 pushes the vertical plate 5 to reset, and the belt alignment detection wheel 7 returns to its initial position.

[0027] In the above structure, the elastic support of spring 9 and the sliding engagement of the swing pin 4 with the strip hole 801 achieve elastic installation of the belt deviation detection wheel 7. Compared with the rigid connection of the belt deviation sensor in the prior art, this structure significantly reduces the impact stress on the belt edge through the buffering effect of spring 9 when the belt deviates, effectively reducing problems such as rubber cracking and exposed wire rope, and reducing the risk of belt tearing accidents. At the same time, the engagement of swing pin 4 and nut 10 can adjust the preload of spring 9 to adapt to the deviation correction needs under different working conditions, and the structure is simple and compact, and easy to maintain.

[0028] In the specific structure of the support mechanism 2, the support mechanism 2 includes a crossbeam I 201 and a crossbeam II 202. A longitudinal beam 203 is connected between the crossbeam I 201 and the crossbeam II 202. A hydraulic cylinder 14 is installed on the longitudinal beam 203. The cylinder body of the hydraulic cylinder 14 is hinged to one side of the longitudinal beam 203. The piston rod of the hydraulic cylinder 14 is rotatably connected to a traction plate 15. The traction plate 15 is fixed to one side of the roller assembly 1. The bottom of the roller assembly 1 is rotatably installed above the crossbeam I 201.

[0029] In this embodiment, as Figure 2 As shown, crossbeams I 201 and II 202 are arranged in parallel, and two longitudinal beams 203 are provided, spaced apart and vertically connected between crossbeams I 201 and II 202, forming a frame structure. A hydraulic cylinder 14 is horizontally installed in the middle of one of the longitudinal beams 203. The cylinder body of the hydraulic cylinder 14 is hinged to the longitudinal beam 203 via a hinged seat, and the piston rod can extend and retract horizontally. One side of the traction plate 15 is rotatably connected to the piston rod of the hydraulic cylinder 14, and the other side is welded and fixed to the side of the idler assembly 1. The middle position of the bottom of the idler assembly 1 is rotatably connected to the middle position of crossbeam I 201, thereby enabling the idler assembly 1 to swing in the horizontal plane. Thus, when the piston rod of the hydraulic cylinder 14 extends and retracts, the traction plate 15 drives the idler assembly 1 to swing, achieving belt correction. In the above structure, the arrangement of the hydraulic cylinder 14 and the traction plate 15 allows for automatic adjustment of the angle of the idler assembly 1 based on the feedback signal from the correction detection wheel 7, achieving fully automatic correction.

[0030] In the specific structure of the idler assembly 1, the idler assembly 1 includes a horizontal frame 101, which is mounted on a crossbeam I 201 via a pivot at the center of its bottom. A horizontal idler 103 is mounted on the horizontal frame 101, and side frames 102 are fixed at both ends of the horizontal frame 101. Side idlers 104 are mounted on the side frames 102.

[0031] In this embodiment, as Figure 1 , Figure 2 As shown, the horizontal frame 101 is in the shape of an "I" (a straight line), and the horizontal idlers 103 are evenly arranged on the upper surface of the horizontal frame 101 along the belt running direction to support the middle of the belt. The side frame 102 is in the shape of an "L" (another straight line), and is fixed at both ends of the horizontal frame 101 at an angle. The side idlers 104 are installed on the side frame 102, and their axes form a certain angle with the axes of the horizontal idlers 103 to guide the edge of the belt. In the above structure, the combination of the horizontal idlers 103 and the side idlers 104 forms a trough-shaped idler group, which can effectively improve the belt's load-bearing capacity and stability. Therefore, when the idler assembly 1 swings, the side idlers 104 can generate a lateral thrust on the edge of the belt, which is beneficial for assisting the belt to return to its correct position and improving the correction efficiency.

[0032] Specifically, a bearing housing 16 is fixed in the middle of the crossbeam I 201, and a bearing is installed inside the bearing housing 16. The bearing engages with a rotating shaft below the horizontal frame 101. In this embodiment, a deep groove ball bearing is installed inside the bearing housing, and the rotating shaft is rotatably connected to the bearing housing 16 through the bearing. The bearing reduces the frictional resistance when the idler roller assembly 1 swings, making the correction action more sensitive, while also reducing mechanical wear and extending the maintenance cycle of the equipment.

[0033] More specifically, rollers 105 are installed at both ends of the bottom of the horizontal frame 101, and a support plate 17 is supported below each roller 105. The support plate 17 is fixed to the crossbeam I 201. In this embodiment, as... Figure 2 As shown, rollers 105 are symmetrically installed at both ends of the bottom of the horizontal frame 101. The support plate 17 is a horizontally arranged steel plate fixed to the upper surface of the crossbeam I 201. The upper surface of the support plate 17 can contact the rollers 105, forming a rolling support for the rollers 105. When the roller assembly 1 swings, the rollers 105 roll on the support plate 17, further reducing the swing resistance. The symmetrically arranged rollers 105 and support plate 17 form a double-support structure, which improves the stability of the roller assembly 1 and avoids tilting or jamming caused by single-point support.

[0034] In the specific structure of the inspection and drive support 3, the inspection and drive support 3 includes a column 301. The lower end of the column 301 is fixed to the support mechanism 2, and a channel steel 302 is fixed to the upper end of the column 301. The web of the channel steel 302 is welded to the column 301, and the slot of the channel steel 302 faces upward. In this embodiment, the column 301 is vertically fixed to the end of the crossbeam II 202, and the channel steel 302 is horizontally fixed to the top of the column 301. Its web is welded to the top of the column 301 to form a stable support structure. The slot of the channel steel 302 faces upward, thereby providing space for the installation of the swing pin 4 and the vertical plate 5.

[0035] like Figure 3 As shown, the horizontal plate 8 has two strip-shaped holes 801, and a pivot pin 4 passes through each of the two strip-shaped holes 801. The lower ends of the two pivot pins 4 are rotatably connected to the two flanges of the channel steel 302, respectively. In this embodiment, the horizontal plate 8 is a steel plate, and the two strip-shaped holes 801 are located on the side away from the vertical plate 5 and are arranged in parallel. The lower end of the pivot pin 4 is rotatably connected to the flange of the channel steel 302 by a pin, and the upper end of the pivot pin 4 is fixed with a nut 10 after passing through the strip-shaped hole 801. The double pivot pin 4 structure makes the swing of the vertical plate 5 more stable, avoids the skewing or twisting that may occur with a single pivot pin 4, ensures that the correction detection wheel 7 is always in perpendicular contact with the edge of the belt, and improves the accuracy of the detection.

[0036] Specifically, the alignment pump 6 is installed at the top of the vertical plate 5. A sleeve 501 is located at the lower end of the vertical plate 5, through which a pin 502 passes. Both ends of the pin 502 are connected to the two flanges of the channel steel 302. In this embodiment, the alignment pump 6 is fixed to the top of the vertical plate 5 with bolts, and its installation height is higher than the height plane of the horizontal plate 8. The sleeve 501 at the lower end of the vertical plate 5 is a circular tube structure. The pin 502 passes through the through holes of the sleeve 501 and the flanges of the channel steel 302, forming a hinge fulcrum. This structure ensures that when the vertical plate 5 is impacted by the belt, it flips away from the belt and the center of gravity shifts downward, thereby compressing the spring 9.

[0037] The working process of this device is as follows: When the belt slips off-center, the edge of the slipping belt contacts and pushes the correction detection wheel 7 on one side to rotate. The correction detection wheel 7 drives the correction oil pump 6 to operate, and the hydraulic oil in the oil reservoir below the correction oil pump 6 is transported to the hydraulic cylinder 14 through the oil pipe, pushing the piston rod of the hydraulic cylinder 14 to move. The piston rod is connected to the idler assembly 1 through the traction plate 15, causing the idler assembly 1 to swing around the connection position between its bottom and the support mechanism 2, so that the idler forms an inclined angle. The friction between the belt and the idler generates a lateral force to correct the belt towards the center position.

[0038] When the belt misalignment impacts the correction detection wheel 7, the vertical plate 5 moves laterally under force, causing the swing pin to slide within the slot 801 of the horizontal plate 8. Simultaneously, it compresses the spring 9 nested around the swing pin 4. The spring 9 absorbs the impact energy through elastic deformation, causing the correction detection wheel 7 to swing, preventing a rigid collision between the belt and the detection wheel 7. When the belt deviation decreases or the impact disappears, the spring force of the spring 9 pushes the horizontal plate 8 back to its original position, preparing the correction detection wheel 7 for the next correction trigger. Throughout this process, the swing pin 4 acts as a hinge fulcrum, and in conjunction with the spring force of the spring 9, achieves the elastic installation of the correction detection wheel 7, avoiding rigid impact between the correction detection wheel 7 and the belt edge, reducing the probability of belt wear and safety hazards, and lowering maintenance costs.
