Description

Technical Field

[0001] The present invention relates to the field of bending amount detection, and more specifically, to a bending amount detection system and method for a carrying roller. Background Art

[0002] The carrying roller is an important component of the belt conveyor. There are many types and a large number of them. It can support the weight of the conveyor belt and the material. Detecting the bending degree of the carrying roller is an important link to ensure the efficient and stable operation of the conveying system. The reasons for detecting the bending degree include the following aspects:

[0003] Avoid deviation: A bent carrying roller will cause uneven stress on the conveyor belt, resulting in deviation, causing edge wear or tearing.

[0004] Reduce vibration: A bent carrying roller will generate abnormal vibration and noise during high-speed operation, affecting the stability of the equipment.

[0005] Uniform stress: A carrying roller with an excessive bending degree will cause local pressure concentration on the conveyor belt, accelerating the wear of the carrying roller bearings and seals.

[0006] Reduce maintenance costs: Timely replacement of bent carrying rollers can avoid collateral damage to other components and reduce the frequency of downtime for maintenance.

[0007] Among them, the detection of the bending degree of the carrying roller generally uses rotational detection: the carrying roller is installed on the test bench for rotation, and a dial indicator is used to measure the radial runout. However, when using a dial indicator for measurement, only the middle part of the carrying roller can be detected, and it is difficult to detect the entire carrying roller, resulting in poor detection effects.

[0020] A detection method for a bending amount detection system of a carrying roller, comprising the following steps:

[0021] S1: Installation. Take out the inner shaft of the carrying roller, then insert the carrying roller on the surface of the cylinder. The motor box drives the screw rod to rotate, driving the driving plate to drive the ejecting block to snap into the inside of the carrying roller, and the first cross bar abuts against both sides of the carrying roller.

[0022] S2: Adjustment. Move the adjustment plate. The bottom of the correction rod contacts both sides of the carrying roller. Rotate the rotating disk, move the dial indicator to the position of the correction groove, rotate the rotating disk, and the pointer of the dial indicator is at the bottom of the correction groove. Then repeat the operation until the pointer of the dial indicator reaches the bottom of the other correction groove. Compare the values of the dial indicator at the bottoms of the two correction grooves, and then rotate the rotating disk again so that the pointer of the dial indicator points to the carrying roller.

[0023] S3: Detection. Rotate the extrusion disk, the limiting rod snaps into the screw rod, rotate the screw rod to drive the cylinder to rotate, the cylinder rotation drives the carrying roller to rotate, move the dial indicator, and the dial indicator detects different positions of the rotating carrying roller.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In this solution, by moving the dial indicator, the dial indicator moves on the surface of the mounting rod. By fitting the pointer of the dial indicator with the surface of one end of the carrying roller, the contact point at this time is the reference point. Then move the dial indicator to move the dial indicator to the other side of the carrying roller. During the movement, different positions of the carrying roller are detected, so as to obtain the height difference between other position detection points and the reference point, and then the bending degrees of different positions of the carrying roller can be obtained. More detected values are available, and the applicable range is wider.

[0026] 2. In this solution, the distance from the bottom of the correction rod to the center of the rotating disk is the same as the distance from the end point of the detection needle of the dial indicator to the center of the rotating disk. After the correction rod contacts both sides of the carrying roller, it is convenient to rotate the second annular disk to rotate the correction rod and the dial indicator by 180 degrees, so that the end point of the pointer of the dial indicator reaches the position where the correction rod contacts the carrying roller. At this time, the reference point of the carrying roller is determined, and it is more convenient to determine the reference point. And the adjustment plate can move inside the detection frame, which is convenient to adjust the height of the detection mechanism according to the size of the carrying roller, and the applicable range is wider. Rotate the mounting rod again to rotate the mounting rod with the dial indicator by 180 degrees, and then move the dial indicator to move the dial indicator from one side of the carrying roller to the other side of the carrying roller to detect the carrying roller. And the movement of the dial indicator can detect carrying rollers with different diameters and lengths, and the applicable range is wider.

[0027] 3. In this scheme, a spring sheet is fixedly connected to the bottom of the groove, and the spring sheet is squeezed by moving the pop-up block into the driving plate to deform the spring sheet, so that the pop-up block can return to its original position under the action of the spring sheet. The pop-up block extends out under the action of the spring sheet, and the pop-up block can resist the inner wall of the roller, so that the axis of the roller coincides with the axis of the cylinder, which is more convenient for fixing the roller.

[0028] 4. In this scheme, the first cross bar lifts up the connection between the second cross bar, and finally the first cross bar and the cylinder are vertical. When the driving plate moves the cross plate toward the roller, the first cross bar presses against the roller to fix the roller again. It is more convenient to fix the roller and can fix rollers of different sizes. When the cross plate reaches the position of the cross groove, the first cross bar is not blocked by the cylinder. The first cross bar extends from the cross groove to prevent the extended first cross bar from affecting the placement of the roller on the surface of the cylinder, and the cylinder is rotated in the opposite direction to return the driving plate to its original position. At this time, the side wall of the cylinder squeezes the second cross bar, so that the second cross bar brings the first cross bar back to its original position, which is convenient for detecting other rollers again and more convenient.

[0029] 5. In this solution, when the limit rod moves under the pressure of the extrusion disk, the limit rod squeezes the second spring, causing the second spring to change from a naturally extended state to a tight state, so that the limit rod can return to its original position. When the second spring is in a naturally extended state, the limit rod extends into the interior of the limiting groove to achieve the first annular disk and the cylinder to remain fixed, preventing the rotating cylinder from affecting the fixation of the roller when the roller is installed.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 to 10, a bending amount detection system for a carrying roller, comprising a detection frame 1. At the bottom between the two vertical plates of the detection frame 1, a clamping mechanism 5 is provided. The clamping mechanism 5 includes a cylinder 51 for fixing the carrying roller. After taking out the inner shaft of the carrying roller, the cylinder 51 is inserted into the position of the carrying roller shaft, effectively preventing the force application point from not being in the middle of the carrying roller, and causing the bending deformation point of the carrying roller to be on both sides of the carrying roller, resulting in difficulty in fixing the carrying roller, with a wider application range. At the top between the two vertical plates of the detection frame 1, a detection mechanism 4 is provided. The detection mechanism 4 includes an adjustment plate 46 slidably connected to the opposite surfaces of the two vertical plates, a rotating disk 45 rotatably connected to the opposite surfaces of the two adjustment plates 46. Fixedly connected to the opposite surfaces of the two rotating disks 45 are connecting rods 43. Between the two connecting rods 43, a mounting rod 42 is fixedly connected. A dial indicator 3 is slidably connected to the surface of the mounting rod 42. By moving the dial indicator 3, the dial indicator 3 moves on the surface of the mounting rod 42. By fitting the pointer of the dial indicator 3 to the surface of one end of the carrying roller, the contact point at this time is the reference point. Then, the dial indicator 3 is moved so that the dial indicator 3 moves to the other side of the carrying roller. During the movement, different positions of the carrying roller are detected, so as to obtain the height difference between the detection points at other positions and the reference point, and further the bending degree of different positions of the carrying roller can be obtained. More detection values are obtained, and the application range is wider.

[0044] Such as Figures 1 to 10As shown, a second annular disk 41 is rotatably connected to the opposite surface of the adjustment plate 46. By rotating the second annular disk 41, the second annular disk 41 is on the surface of the adjustment plate 46. By rotating the connecting rod 43, the rotation of the mounting rod 42 can be controlled by rotating the connecting rod 43, making the rotation of the mounting rod 42 more convenient. And when the mounting rod 42 rotates, it can drive the dial indicator 3 to rotate. A correction rod 44 is connected to the bottom between the two second annular disks 41. Since the correction rod 44 is parallel to the cylinder 51, after the idler is fixed on the surface of the cylinder 51, by moving the adjustment plate 46, the adjustment plate 46 drives the second annular disk 41, the connecting rod 43, the correction rod 44 and the rotating disk 45 to move downward, facilitating the correction rod 44 to fit with the surface of the idler. The distance from the bottom of the correction rod 44 to the center of the rotating disk 45 is the same as the distance from the end point of the detection needle of the dial indicator 3 to the center of the rotating disk 45. After the correction rod 44 contacts both sides of the idler, by rotating the second annular disk 41, the correction rod 44 and the dial indicator 3 are rotated 180 degrees, facilitating the pointer end point of the dial indicator 3 to reach the position where the correction rod 44 contacts the idler. At this time, the reference point of the idler is determined, making it more convenient to determine the reference point. And the adjustment plate 46 can move inside the detection frame 1, facilitating the adjustment of the height of the detection mechanism 4 according to the size of the idler, with a wider range of applications. Both sides of the correction rod 44 extend downward to form correction grooves 441, and the bottom of the correction rod 44 is on the same horizontal plane as the bottom of the correction grooves 441. By rotating the second annular disk 41, the second annular disk 41 drives the correction rod 44 to rotate. After the correction rod 44 rotates 180 degrees, the correction grooves 441 rotate with the correction rod 44. At this time, the openings of the correction grooves 441 face downward. Then rotate the mounting rod 42 to rotate the mounting rod 42 and the dial indicator 3. At this time, the pointer of the dial indicator 3 points downward. Then move the dial indicator 3 to the position of the correction grooves 441, and rotate the mounting rod 42 again to drive the dial indicator 3 to rotate, making the pointer of the dial indicator 3 point upward again, facilitating the dial indicator 3 to contact the bottom of the correction grooves 441. The dial indicator 3 detects the correction grooves 441, and then repeat the operation of testing the correction grooves 441 to detect the other correction grooves 441. When the detection results of the two correction grooves 441 are the same and the pointer is 0, the idler can be detected at this time. If the detection results of the two correction grooves 441 are the same and the pointer is other values, it can be obtained that the dial indicator 3 is not zeroed and needs to be zeroed. If the detection results of the two correction grooves 441 are different, it means that the correction rod 44 is bent and the device needs to adjust the correction rod 44 to make the measurement of the idler by the device more accurate. Then rotate the mounting rod 42 again to drive the dial indicator 3 to rotate 180 degrees, and then move the dial indicator 3 to move the dial indicator 3 from one side of the idler to the other side of the idler to detect the idler. And the movement of the dial indicator 3 can detect idlers with different diameters and lengths, with a wider range of applications.

[0045] As Figures 1 to 10As shown, the cylinder 51 is rotatably connected with a screw rod 52, and the surface of the screw rod 52 is spirally connected with two driving plates 53. The threads of the two driving plates 53 are in opposite directions, so that the screw rod 52 can be rotated to drive the driving plates 53 to move relatively. The two driving plates 53 are internally slidably connected with an ejection block 531. By moving the driving plate 53, the driving plate 53 can move with the ejection block 531. The cylinder 51 is provided with a transverse groove 511 corresponding to the moving track of the ejection block 531 to accommodate the movement of the ejection block 531, so that the ejection block 531 can leave the driving plate 53 and extend from the transverse groove 511. The ejection block 531 reaches the outside of the cylinder 51, and moves toward the middle of the cylinder 51 by the ejection block 531. The roller on the surface of the cylinder 51 can be squeezed so that the roller is in the middle of the cylinder 51, which is convenient for detecting the roller. The end of the ejection block 531 away from the driving plate 53 is arc-shaped. When the roller is in the cylinder 51 After the part is moved, the driving plate 53 continues to rotate with the screw rod 52, and the driving plate 53 continues to move with the ejection block 531, and the ejection block 531 is squeezed by the roller and returns to the inside of the driving plate 53, and the driving plate 53 moves with the ejection block 531 to the inside of the cylinder 51. The driving plate 53 is provided with a groove 532 corresponding to the moving trajectory of the ejection block 531. The groove 532 facilitates the movement of the ejection block 531 in the driving plate 53, making the movement of the ejection block 531 more convenient. The groove bottom of the groove 532 is fixedly connected with a spring piece 533, and the ejection block 531 moves into the driving plate 53 to squeeze the spring piece 533, so that the spring piece 533 is deformed, so that the ejection block 531 can return to its original position under the action of the spring piece 533, and the ejection block 531 extends out under the action of the spring piece 533, and the ejection block 531 can abut against the inner wall of the roller, so that the axis of the roller coincides with the axis of the cylinder 51, which is more convenient for fixing the roller.

[0046] like Figures 1 to 10As shown in the figure, a cross plate 54 is fixedly connected to one side of the driving plate 53 close to the vertical plate of the detection rack 1. A connecting block 542 is slidably connected inside the cross plate 54. The bottom of the connecting block 542 extends downward to form an extension block 544. The connecting block 542 moves inside the cross plate 54, and the connecting block 542 drives the extension block 544 to move inside the cross plate 54. A first spring 543 is welded to the right side of the cross plate 54. The first spring 543 is in a tense state, which facilitates the first spring 543 to drive the extension block 544 to move, so that the extension block 544 drives the connecting block 542 to move inside the cross plate 54, making the movement of the cross plate 54 more convenient. A first cross bar 541 is rotatably connected to the side of the connecting block 542 away from the driving plate 53. By moving the connecting block 542, the first cross bar 541 can be driven to move inside the cross plate 54. A second cross bar 545 is rotatably connected to the side of the first cross bar 541 away from the connecting block 542. The side of the second cross bar 545 away from the first cross bar 541 is rotatably connected to the cross plate 54, which facilitates the joint of the first cross bar 541 and the second cross bar 545 to tilt upward. Finally, the first cross bar 541 is perpendicular to the cylinder 51. When the driving plate 53 drives the cross plate 54 to move towards the idler, the first cross bar 541 abuts against the idler, and the idler is fixed again, making it more convenient to fix the idler and capable of fixing idlers of different sizes. When the cross plate 54 reaches the position of the cross groove 511, the first cross bar 541 is not blocked by the cylinder 51, and the first cross bar 541 extends out from the cross groove 511, preventing the extended first cross bar 541 from affecting the placement of the idler on the surface of the cylinder 51. And by rotating the cylinder 51 in the reverse direction, the driving plate 53 returns to its original position. At this time, the side wall of the cylinder 51 presses against the second cross bar 545, causing the second cross bar 545 to drive the first cross bar 541 back to its original position, facilitating the detection of other idlers again and making the detection more convenient.

[0047] As Figures 1 to 10As shown in the figure, the left side of the cylinder 51 penetrates through the detection frame 1 and extends to the outside of the detection frame 1. The left side of the lead screw 52 penetrates through the cylinder 51 and extends to the outside of the detection frame 1. The right side of the detection frame 1 is fixedly connected with a motor box 2. The output shaft of the motor in the motor box 2 is connected with the lead screw 52 through a belt. By rotating the output shaft of the motor in the motor box 2, the lead screw 52 can be rotated, making the rotation of the lead screw 52 more convenient. A conversion mechanism 6 is arranged on the surface of the cylinder 51. The conversion mechanism 6 includes a pressing disk 61 rotatably connected to the surface of the cylinder 51. By rotating the pressing disk 61, the pressing disk 61 rotates on the edge of the cylinder 51. A protrusion 611 extends from the inside of the pressing disk 61 towards the center of the circle. When the pressing disk 61 rotates, the protrusion 611 can be driven to rotate. A limiting rod 62 is slidably connected to the left surface of the cylinder 51. During the rotation of the protrusion 611, the protrusion 611 presses the inclined surface of the limiting rod 62, causing the limiting rod 62 to move under the extrusion. The limiting rod 62 moves towards the lead screw 52, so that the limiting rod 62 extends into the inside of the lead screw 52, realizing the fixation of the limiting rod 62 and the lead screw 52, and realizing that when the lead screw 52 rotates, it can drive the cylinder 51 to rotate. When the lead screw 52 rotates but the cylinder 51 does not rotate, it is convenient for the clamping mechanism 5 to fix the idler roller. When the lead screw 52 rotates and drives the cylinder 51 to rotate, the cylinder 51 rotates and drives the idler roller to rotate, which is convenient for the dial indicator 3 to detect the idler roller and makes the detection more convenient. A second spring 63 is welded inside the left side of the cylinder 51. When the limiting rod 62 moves under the extrusion of the pressing disk 61, the limiting rod 62 presses the second spring 63, causing the second spring 63 to change from the natural stretching state to the tense state, which is convenient for the limiting rod 62 to return to its original position. A first annular disk 11 is fixedly connected to the left surface of the detection frame 1. A limiting groove 111 for the limiting rod 62 to extend into is formed on the surface of the first annular disk 11. When the second spring 63 is in the natural stretching state, the limiting rod 62 extends into the inside of the limiting groove 111, realizing the fixation of the first annular disk 11 and the cylinder 51, and preventing the rotating cylinder 51 from affecting the fixation of the idler roller during the installation of the idler roller.

[0048] A detection method for a bending amount detection system of an idler roller includes the following steps:

[0049] S1: Installation. Take out the inner shaft of the idler roller, then insert the idler roller on the surface of the cylinder 51. The motor box 2 drives the lead screw 52 to rotate, driving the driving plate 53 to drive the ejector block 531 to snap into the inside of the idler roller, and the first cross bar 541 abuts against both sides of the idler roller.

[0050] S2: Adjustment. Move the adjustment plate 46. The bottom of the correction rod 44 contacts the idler twice. Rotate the rotating disk 45. Move the dial indicator 3 to the position of the correction groove 441. Rotate the rotating disk 45 until the pointer of the dial indicator 3 is at the bottom of the correction groove 441. Then repeat the operation until the pointer of the dial indicator 3 reaches the bottom of the other correction groove 441. Compare the values of the dial indicator 3 at the bottoms of the two correction grooves 441. Then rotate the rotating disk 45 again so that the pointer of the dial indicator 3 points to the idler.

[0051] S3: Detection. Rotate the extrusion disk 61. The limit rod 62 is engaged in the lead screw 52. Rotate the lead screw 52 to drive the cylinder 51 to rotate. The rotation of the cylinder 51 drives the idler to rotate. Move the dial indicator 3 to detect different positions of the rotating idler.
