Description

Technical Field

[0001] The invention relates to the technical field of tubular belt conveyors, in particular to a tightening and twisting tubular conveyor deviation correction device. Background Art

[0002] Most of the existing methods to solve the torsion of tubular belts are to install material baffles or manually adjust rollers. However, such adjustment methods can only be debugged after the machine is shut down, and cannot be corrected during operation, which greatly affects the progress of material transportation. The invention patent with application number CN202410479375.4 discloses a tubular conveyor belt anti-twist adjustment roller group, including a tubular belt in a feeding section and a tubular belt in a return section. The rollers on both sides increase the clockwise friction force respectively to force the state of the tubular belt to be adjusted, thereby correcting the deviation of the tubular belt, improving the stability of the tubular belt conveying system, and reducing the occurrence of leakage of liquid slurry conveyed by the tubular belt.

[0003] Although the device has the above advantages, it still has the following defects in actual use:

[0004] 1) The device corrects the deviation by the friction damping effect of the adjustment component, and the correction force is small, resulting in poor actual correction effect;

[0005] 2) The device monitors the tubular belt through a pressure module and performs forced correction to a certain extent. First, its effective area is small, resulting in poor correction effect. Secondly, forced correction causes increased force, which can easily cause damage to the pressure module and affect the accuracy of subsequent monitoring results.

The shaft gear 8 is composed of a shaft rod and a gear, and the number and position of the gears on the shaft rod are adapted to the arc rack 3, which can support the arc rack 3. The ends of the two coupling gears 8 are fixedly connected with bearing supports 9. The connection between the bearing supports 9 and the shaft rod of the coupling gear 8 has a rotation damping measure to improve the stability of the arc rack 3 when it is not closed. The outer surfaces of the bearing supports 9 on both sides are fixedly connected to the outer surfaces of the support plate 7 and the slide plate 2 respectively. The outer surface of the arc rack 3 is provided with a waist groove 10. The waist groove 10 is arranged in an arc shape and is coaxially arranged with the arc rack 3. The inside of the waist groove 10 is movably connected with a clamping wheel 11. The clamping wheel 11 rolls inside the waist groove 10 to facilitate the rotation of the arc rack 3. At least two clamping wheels 11 are arranged to enhance the balanced support effect on the arc rack 3, and to fix the path and guide its movement. The outer surface of the clamping wheel 11 is rotatably connected with a fixed plate 12, and the outer surface of the fixed plate 12 is fixedly connected to the outer surface of the support plate 7.

[0041] In this embodiment, the driving motor 6 is powered on to drive the two slides 2 to move, so that the arc-shaped racks 3 on both sides approach each other and close together, so that they are sleeved on the outside of the tubular belt and coaxial with the tubular belt. When the tubular belt is twisted, the arc-shaped rack 3 is driven by the coupling gear 8 and can rotate to force the tubular belt to correct the deviation. At the same time, during the rotation process, the clamping wheel 11 moves inside the waist groove 10 through the support of the fixed plate 12 to support, guide and limit the movement of the arc-shaped rack 3.

[0042] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 ;

[0043] The roller assembly 4 includes a roller frame 41, which is composed of a U-shaped frame and rotating rollers, and at least two rotating rollers are arranged on the ∪-shaped frame to improve the axial contact area and the correction effect. At the same time, the roller frame 41 is provided with multiple groups of equal angles along the axial direction of the arc-shaped rack 3. A telescopic rod 42 is arranged on the outside of the roller frame 41. The telescopic rod 42 is made of an existing electric push rod and is electrically connected to an external control circuit. By controlling the roller frame 41 to move toward the axis of the arc-shaped rack 3, tubular belts of different sizes can be corrected. The outer surface of the telescopic rod 42 is fixedly connected to a mounting plate 43, and the outer surface of the mounting plate 43 is fixedly connected to the outer surface of the arc-shaped rack 3. The output end of the telescopic rod 42 is fixedly connected to a sleeve 44, and a sliding rod 45 is slidably connected to the inside of the sleeve 44. One end of the sliding rod 45 is fixedly connected to the outer surface of the roller frame 41, and the other end of the sliding rod 45 is fixedly connected to a stop plate 46. The stop plate 46 has a rectangular cross-section and plays a role in correction. The sleeve 44 has a forming and limiting function, and a displacement sensor is arranged inside the sleeve 44. By monitoring the position of the butt plate 46, the torsion of the tubular belt is monitored. The outer surface of the butt plate 46 is slidably connected to the inside of the sleeve 44. The outer surface of the butt plate 46 is movably connected to a cam 47. There are displacement grooves on both sides of the rotation axis of the cam 47 to provide space for the movement of the butt plate 46. The outer surface of the cam 47 is fixedly connected to a rotating motor 48. The rotating motor 48 is electrically connected to an external control circuit, and the external control circuit is electrically connected. The outer surface of the rotating motor 48 is fixedly connected to the inside of the sleeve 44. The outer surface of the slide rod 45 is sleeved with a compression spring 49. The elastic force of the compression spring 49 is greater than the force applied to the roller frame 41 during normal tubular belt movement, and it can play a certain correction role through its own elastic force, and it is convenient for the roller frame 41 to reset after movement. The ends of the compression spring 49 are respectively fixedly connected to the outer surface of the butt plate 46 and the inside of the sleeve 44.

[0044] In this embodiment, when the arc-shaped rack 3 is closed, the output end of the telescopic rod 42 extends out to drive the roller frame 41 to move and contact the surface of the tubular belt. Then, the rotating motor 48 drives the cam 47 to rotate, so that the other end of the cam 47 faces the abutment plate 46, thereby providing space for the movement of the abutment plate 46. When the tubular belt is twisted, the corresponding roller frame 41 is pushed to move, so that the sliding rod 45 drives the abutment plate 46 to move synchronously inside the sleeve 44, and at the same time, the compression spring 49 is stretched. Then, the displacement sensor detects the movement of the abutment plate 46, and then the rotating motor 48 drives the cam 47 to rotate, and the other end of the cam abuts against the abutment plate 46 to move, and the compression spring 49 is compressed to the limit, so that the position of the roller frame 41 is fixed and is on the outer periphery of the tubular belt when it is normal. Then, through the rotation of the arc-shaped rack 3, the roller frame 41 can follow the movement to correct the deviation of the tubular belt. After the deviation correction is completed, the cam 47 is again separated from the fixation to the roller frame 41, so that the roller frame 41 performs the monitoring work again.
