TECHNICAL FIELD

[0001] The present application relates to the technical field of belt conveyors, in particular to a belt conveyor drum device with automatic deviation correction function. BACKGROUND

[0002] In industrial production, belt conveyors, as key equipment for material transportation, are widely used in mining, metallurgy, building materials, chemical industry and other fields. One of the core components of the belt conveyor is the drum device, which directly affects the running stability and service life of the conveyor belt. However, in the actual operation process, the conveyor belt often deviates, which not only causes the conveyor belt to wear out and reduces the service life of the equipment, but also may cause material spillage, equipment failure and other serious problems, affecting the continuity and safety of production.

[0003] With the continuous development of automation technology, some belt conveyor drum devices with automatic deviation correction function have emerged. However, the existing automatic deviation correction devices have the problems of complex structure, low correction efficiency, poor reliability, etc., which cannot meet the requirements of industrial production for equipment stability and efficiency. For example, some devices cannot quickly and effectively drive the deviation correction components to act after detecting the deviation of the conveyor belt, resulting in delayed correction; the contact mode of the correction components of some devices with the conveyor belt is unreasonable, which may easily damage the conveyor belt.

[0004] During the operation of the belt conveyor, the diameter of the outer wall of the drum may change due to factors such as wear and tear and temperature change, which will affect the tension distribution of the conveyor belt and further affect the running stability of the conveyor belt. The existing drum device lacks real-time detection and adjustment mechanism for the diameter of the outer wall of the drum, and cannot timely discover and solve the problems caused by the change of the diameter of the drum. At the same time, the detection components are prone to accumulate dust and dirt during long-term use, affecting the accuracy of detection, and most of the existing devices do not have effective cleaning devices.

[0021] Wherein, the centrifugal force generated when the rotating drum II rotates drives the U-shaped base and the rolling wheel to move outward and stretch the tension spring I.

[0022] In a possible design, the driving structure further comprises:

[0023] A base plate is fixed to the inner wall of one side of the U-shaped mounting base plate; a sliding guide rod II is slidably penetrated through the base plate; an arc-shaped support plate is fixed to one end of the sliding guide rod II close to the U-shaped base, and the inner concave surface thereof is matched with the rolling wheel; a moving base is fixed to one end of the sliding guide rod II away from the arc-shaped support plate; a tension spring II is sleeved on the outer wall of the sliding guide rod II, and the two ends thereof are respectively in abutment with the moving base and the base plate; an inclined groove is arranged in the moving base; a vertical groove is arranged in the inner wall of one side of the U-shaped mounting base plate; a positioning pin rod is fixedly connected at one end with the mounting strip plate and slidably connected at the other end in the inclined groove and the vertical groove.

[0026] In a possible design, the top of the installation base frame is provided with arc-shaped guide rail grooves, and the bottom of the U-shaped installation support is fixed with positioning pin columns which are in sliding cooperation with the arc-shaped guide rail grooves, for limiting the deflection angle of the U-shaped installation support.

[0027] In a possible design, the bottom of the positioning pin column is embedded with a rolling ball which is in rolling contact with the inner wall of the bottom of the arc-shaped guide rail groove, for supporting the U-shaped installation support and reducing friction.

[0028] In a possible design, the inner part of the U-shaped support frame and the outer wall of the rotating wheel are both fixed with rotating seats, and the worm is rotatably penetrated through the two rotating seats through a bearing, for increasing the rotating stability of the worm.

[0029] In a possible design, the tensioning and buffering mechanism comprises:

[0030] two installation panels fixed to the top of the installation base frame, sliding guide grooves arranged in the installation panels, sliding bases slidingly connected in the sliding guide grooves, tension springs III with two ends respectively connected with the sliding bases and the inner wall of the bottom of the sliding guide grooves, and guide wheels rotatably connected between the two sliding bases and abutting against the inner wall of the transmission belt.

[0031] When one side of the transmission belt is extruded, the guide wheels and the sliding bases can be pressed to move downward against the tension of the tension springs III, so as to provide space for the transmission belt.

[0032] When the transmission belt deviates to one side, the rotating wheel is driven to rotate by the rubber wheel I, the supporting column is extruded by the cooperation of the positioning pin shaft and the frame body, the pressure sensing sensor receives the pressure signal, the distance of the deviation of the transmission belt can be judged, and the output shaft of the hydraulic oil cylinder is controlled to start to extend or contract, so that the pressure of the deviated side of the transmission belt on the rotating drum II is increased, so as to complete the automatic deviation correction of the transmission belt.

The rubber wheel II can drive the deviated conveyor belt to the center, further completing the correction operation and improving the correction efficiency.

[0034] In this invention, when the rotating drum II rotates, it synchronously drives the U-shaped base and the rolling wheel to revolve. Under the action of centrifugal force, the U-shaped base and the rolling wheel move outward, the tension spring I is stretched, the rolling wheel abuts against the inner wall of the arc-shaped support plate and pushes the arc-shaped support plate, the sliding guide rod II and the moving base to move outward, and drives the mounting strip to move up and clean the distance sensing sensor through the cleaning brush, so that the cleaning operation can be automatically completed when the rotating drum II rotates.

[0035] In this invention, the rolling wheel, under the action of centrifugal force, pushes the movable base to move outward through the arc-shaped support plate. The cooperation of the inclined groove and the vertical groove can drive the positioning pin and the mounting strip to move upward along the trajectory of the vertical groove. The mounting strip cleans the distance sensing sensor with a cleaning brush. When the rotating drum II stops running, the mounting strip drives the cleaning brush to move downward and reset, which can clean the distance sensing sensor again, ensuring the cleanliness of the distance sensing sensor and facilitating the accurate measurement of the outer diameter of the rotating drum II in the later stage.

[0036] In this invention, the conveyor belt deviation can be automatically detected. Through the cooperation of components such as rubber wheel I and rotating wheel, the pressure sensor receives the signal and controls the hydraulic cylinder to complete the automatic correction, avoiding manual operation, improving efficiency, and reducing conveyor belt wear. On the other hand, an auxiliary correction component is provided. When the conveyor belt deviates, rubber wheel II rotates, driving the deviated conveyor belt towards the center, improving correction efficiency. In addition, when rotating roller II rotates, the drive structure uses centrifugal force to automatically clean the distance sensor with a cleaning brush, ensuring measurement accuracy. It can also clean again when the machine stops running, ensuring sensor cleanliness and facilitating accurate measurement of the outer diameter of rotating roller II. This device can effectively correct conveyor belt deviation, improve correction response speed, maintain sensor detection accuracy, and extend equipment life. Attached Figure Description

DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.

[0049] In an embodiment, referring to Figures 1-8 , the belt conveyor drum device mainly includes an installation base frame 1, a rotating drum I 2, a rotating drum II 3, a conveying belt 4, a deviation correction structure, an auxiliary deviation correction assembly, a distance sensing sensor 24, and a driving structure. The installation base frame 1 serves as the support foundation of the entire device and provides installation positions and fixed supports for other components. The rotating drum I 2 and the rotating drum II 3 are drivingly connected through the conveying belt 4 to realize the conveying function of the materials. The deviation correction structure is used to adjust in time when the conveying belt 4 deviates, and the auxiliary deviation correction assembly improves the deviation correction efficiency. The distance sensing sensor 24 is used to detect the diameters of different positions of the outer wall of the rotating drum II 3, and the driving structure cleans the distance sensing sensor 24 when the rotating drum II 3 rotates.

[0050] Referring to Figure 1 and Figure 5, the installation base 1 is made of high-strength steel material, has good rigidity and stability, and can withstand various loads generated during the operation of the whole device. The top side of the installation base 1 is rotatably connected with a rotating drum I 2 through a rack, and the rack is fixedly connected with the installation base 1 through bolts, so as to ensure that the rotating drum I 2 is firmly installed. The other side of the top of the installation base 1 is rotatably connected with a U-shaped mounting bracket 5 through a rotating shaft, and the U-shaped mounting bracket 5 is rotatably connected with a rotating drum II 3. The rotating shaft is made of high-quality alloy steel, which is precisely machined and heat treated, has high strength and wear resistance, and can ensure the stable rotation of the U-shaped mounting bracket 5 and the rotating drum II 3. The rotating drum I 2 and the rotating drum II 3 are drivingly connected through a transmission belt 4, and the transmission belt 4 is made of high-strength rubber material, which has good elasticity and wear resistance, and can meet the conveying requirements of different materials.

[0051] With reference to Figure 5 and Figure 6 , in order to control the angle of rotation of the U-shaped mounting bracket 5 and avoid damage to the transmission belt 4 caused by too large rotation angle, arc-shaped guide grooves 20 are arranged on both sides of the top of the installation base 1, and positioning pin columns 21 are fixedly arranged on both sides of the bottom of the U-shaped mounting bracket 5, and the positioning pin columns 21 are slidingly matched with the arc-shaped guide grooves 20. The bottom of the positioning pin column 21 is rollingly embedded with a rolling ball 22, and the rolling ball 22 is in contact with the inner wall of the bottom of the arc-shaped guide groove 20. When the U-shaped mounting bracket 5 rotates, the rolling ball 22 can reduce the friction and support the U-shaped mounting bracket 5, so as to avoid the inclination of the U-shaped mounting bracket 5.

[0052] With reference to Figures 1-3 and Figure 5 , the deviation correcting structure is arranged on the top of the installation base 1, mainly including two connecting racks 6, two rotating wheels 7, a base plate 11, a supporting column 12, a frame body 13, a positioning pin shaft 10, a rotating shaft 8, a rubber wheel I 9, a fixed base 14, a sliding guide rod I 15, a fixed disc 16, a spring element 18, a pressure sensing sensor 17 and a hydraulic oil cylinder 19, and a protective cover can be arranged on the outer side of the rotating wheel 7.

[0053] With reference to Figures 1-3 and Figure 5The two connecting frames 6 are fixed on the top of the mounting base 1 and are located on both sides of the conveying belt 4. The base plate 11 is fixed on the side of the connecting frame 6 close to the conveying belt 4, and the top of the base plate 11 is slidingly connected with the support column 12 which can freely slide on the base plate 11 in the horizontal direction. The top of the support column 12 is fixed with the frame body 13. The rotating wheel 7 is rotated on one side of the connecting frame 6, and the side of the rotating wheel 7 deviated from the center is fixed with the positioning pin shaft 10 which extends into the frame body 13 and slidingly cooperates with the frame body 13. When the rotating wheel 7 rotates, the positioning pin shaft 10 slides in the frame body 13, thereby driving the support column 12 to move. The outer wall of the rotating wheel 7 is rotatably provided with the rotating shaft 8, and the top end of the rotating shaft 8 is fixed with the rubber wheel I 9 which abuts against one side of the conveying belt 4. When the conveying belt 4 deviates, the conveying belt 4 touches the rubber wheel I 9 and drives the rotating wheel 7 to rotate. The fixed base 14 is fixed on the top of the base plate 11, and the sliding guide rod I 15 is slidingly arranged in the fixed base 14 and is fixedly connected with the support column 12 at one end. The outer wall of the sliding guide rod I 15 is slidingly sleeved with the fixed disc 16 located on the side of the fixed base 14 close to the support column 12. The outer wall of the sliding guide rod I 15 is sleeved with the spring element 18 which is a cylindrical helical spring with an elastic coefficient range of 50-100 N / mm, a free length range of 50-100 mm and an outer diameter range of 20-40 mm. The two ends of the spring element 18 are respectively abutted against the fixed disc 16 and the support column 12 through the spring seats. A plurality of pressure sensing sensors 17 are embedded on the side of the fixed base 14 close to the support column 12. When the spring element 18 is compressed, the fixed disc 16 applies pressure to the pressure sensing sensor 17 under the elastic force of the spring element 18, and the pressure sensing sensor 17 can detect the pressure received by the fixed disc 16 and transmit the pressure signal to the control system (not shown in the figure). The top of the mounting base 1 is rotatably connected with the hydraulic oil cylinder 19, and the output shaft of the hydraulic oil cylinder 19 is rotatably connected with one side of the U-shaped mounting bracket 5. When the pressure sensing sensor 17 detects the pressure, the control system starts the hydraulic oil cylinder 19 according to the pressure signal, and the output shaft of the hydraulic oil cylinder 19 starts to extend or contract, so that the U-shaped mounting bracket 5 rotates, thereby moving the rotating drum II 3 forward on the side deviated from the conveying belt 4 and backward on the other side, so that the pressure of the rotating drum II 3 on the side deviated from the conveying belt 4 increases and the pressure of the rotating drum II 3 on the other side decreases, and the conveying belt 4 deviates to the side with smaller pressure, thereby completing the automatic deviation correction of the conveying belt 4.

[0054] Referring to Figures 2-4 The auxiliary deviation correction assembly is used to improve the deviation correction efficiency when the deviation correction structure is running, mainly including a U-shaped support frame 45, a power transmission shaft 46, a worm gear 47, a worm 49, an umbrella gear I 50, an umbrella gear II 51 and a rubber wheel II 48.

[0055] With reference to Figure 3 And Figure 4 , the U-shaped support frame 45 is fixed to the outer wall of the rotating wheel 7, and the power transmission shaft 46 is rotatably arranged through the U-shaped support frame 45. The worm gear 47 is fixedly arranged on the outer wall of the power transmission shaft 46 and located in the U-shaped support frame 45. The outer wall of the rotating shaft 8 is fixedly arranged with the umbrella gear II 51, and the U-shaped support frame 45 is rotatably connected with the worm 49, the worm 49 is engaged with the worm gear 47, and one end of the worm 49 is fixedly arranged with the umbrella gear I 50 engaged with the umbrella gear II 51. The outer wall of the power transmission shaft 46 is fixedly arranged with two rubber wheels II 48, and the two rubber wheels II 48 are located on both sides of the power transmission shaft 46. When the transmission belt 4 deviates and pushes the rubber wheel I 9, the friction between the transmission belt 4 and the rubber wheel I 9 drives the rubber wheel I 9 to rotate, and the rubber wheel I 9 drives the worm 49 to rotate through the cooperation of the umbrella gear II 51 and the umbrella gear I 50, and the worm 49 is engaged with the worm gear 47 to drive the power transmission shaft 46 and the rubber wheel II 48 to rotate. When the transmission belt 4 deviates and pushes the rotating wheel 7 to rotate, the rotating wheel 7 drives the rubber wheel II 48 to rotate synchronously through the U-shaped support frame 45, so that the rubber wheel II 48 abuts against the inner wall of the transmission belt 4, and the self-rotation of the rubber wheel II 48 completes the deviation correction of the transmission belt 4. With the increasing of the rotating angle of the rotating wheel 7, the pressure of the rubber wheel II 48 on the inner wall of the transmission belt 4 is gradually increased, and the deviation correction efficiency is further improved.

[0056] With reference to Figure 4 In order to increase the stability of the worm 49 and enable the rotating shaft 8 to stably drive the power transmission shaft 46, the inner part of the U-shaped support frame 45 and the outer wall of the rotating wheel 7 are both fixedly arranged with rotating seats, and the worm 49 is rotatably arranged through the two rotating seats.

A plurality of distance sensing sensors 24 are fixed on the inner wall of the side of the U-shaped mounting base plate 23 away from the rotating drum 13, for detecting the diameters of different positions of the outer wall of the rotating drum 13. Since the diameter of the outer wall of the drum may change due to factors such as wear and temperature change during the operation of the belt conveyor, the diameter of the outer wall of the drum is detected in real time by the distance sensing sensor 24, so that the diameter change can be found in time, so that corresponding measures can be taken for adjustment, to ensure that the tension distribution of the transmission belt is uniform, and to improve the operation stability of the transmission belt. The U-shaped mounting base plate 23 is slidingly connected with a mounting strip plate 38, one side of the mounting strip plate 38 is fixed with a plurality of cleaning brushes 39 (nylon brush filaments, diameter 0.1-0.3mm), and the cleaning brushes 39 cooperate with the distance sensing sensors 24, for cleaning the distance sensing sensors 24, to ensure the accuracy of the measurement of the distance sensing sensors 24. In the long-term use process, dust and dirt are easy to accumulate on the surface of the distance sensing sensor 24, which affects the accuracy of detection, and the cleaning brush 39 can timely remove these impurities, to ensure that the distance sensing sensor 24 is always in good working condition.

[0058] With reference to Figure 5 , Figure 7 , Figure 10 and Figure 8 , the driving structure is arranged at both ends of the rotating drum 13, for driving the cleaning of the distance sensing sensor 24 by the mounting strip plate 38 when the rotating drum 13 rotates.
