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: Avoid deviation: A bent carrying roller will cause uneven stress on the conveyor belt, leading to deviation, resulting in edge wear or tearing.

[0003] Reduce vibration: A bent carrying roller will generate abnormal vibration and noise during high-speed operation, affecting the stability of the equipment.

[0004] Even 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.

[0005] Reduce maintenance costs: Timely replacement of the bent carrying roller can avoid collateral damage to other components and reduce the frequency of shutdown for maintenance.

[0006] 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 and rotated, 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. Summary of the Invention

[0007] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a bending amount detection system and method for a carrying roller. By moving the dial indicator so that the dial indicator moves on the surface of the mounting rod, and by fitting the pointer of the dial indicator to the surface of one end of the carrying roller, the contact point at this time is the reference point. Then move the dial indicator so that the dial indicator 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 at different positions of the carrying roller can be obtained. More detection values are obtained, and the applicable range is wider.

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A bending amount detection system for a carrying roller includes a detection frame. At the bottom between the two vertical plates of the detection frame, a clamping mechanism is provided.

[0015] Furthermore, a first cross bar is rotatably connected to the side of the connecting block away from the drive plate, a second cross bar is rotatably connected to the side of the first cross bar away from the connecting block, and the side of the second cross bar away from the first cross bar is rotatably connected to the horizontal plate.

[0016] Furthermore, the left side of the cylinder penetrates through the detection frame and extends to the outside of the detection frame, the left side of the lead screw penetrates through the cylinder and extends to the outside of the detection frame, a motor box is fixedly connected to the right side of the detection frame, and the output shaft of the motor in the motor box is connected to the lead screw by a belt.

[0017] Furthermore, a conversion mechanism is provided on the surface of the cylinder, the conversion mechanism includes a pressing disk rotatably connected to the surface of the cylinder, a protrusion extends from the inside of the pressing disk towards the center of the circle, a limiting rod is slidably connected to the left surface of the cylinder, a second spring is welded to the left inside of the cylinder, a first annular disk is fixedly connected to the left surface of the detection frame, and a limiting groove for accommodating the insertion of the limiting rod is provided on the surface of the first annular disk.

[0018] A detection method for a bending amount detection system of a carrying roller, comprising the following steps: 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. S2: Adjustment. Move the adjustment plate. The bottom of the correction rod contacts both sides of the carrying roller twice. 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. 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.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 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 to 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 further obtain the bending degree of different positions of the carrying roller. More detection values are obtained, and the applicable range is wider.

[0020] 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 bottom of 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 drive the dial indicator to rotate 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.

[0021] 3. In this solution, a elastic sheet is fixedly connected to the bottom of the groove. By moving the ejecting block into the driving plate to squeeze the elastic sheet, the elastic sheet is deformed, which is convenient for the ejecting block to return to its original position under the action of the elastic sheet. When the ejecting block extends under the action of the elastic sheet, the ejecting block can abut against the inner wall of the carrying roller, making the axis of the carrying roller coincide with the axis of the cylinder, which is more convenient for fixing the carrying roller.

[0022] 4. In this solution, when the first crossbar drives the connection point of the second crossbar to tilt upwards, the first crossbar finally becomes perpendicular to the cylinder. When the driving plate drives the crossplate towards the idler roller, the first crossbar abuts against the idler roller, fixing the idler roller again. It is more convenient to fix the idler roller and can fix idler rollers of different sizes. When the crossplate reaches the position of the transverse groove, without the obstruction of the cylinder, the first crossbar extends out from the transverse groove, preventing the extended first crossbar from affecting the placement of the idler roller on the surface of the cylinder. And by rotating the cylinder in the reverse direction, the driving plate returns to its original position. At this time, the side wall of the cylinder presses against the second crossbar, causing the second crossbar to drive the first crossbar back to its original position, facilitating the detection of other idler rollers again and making the detection more convenient.

[0023] 5. In this solution, when the limiting rod moves under the extrusion of the extrusion disc, the limiting rod squeezes the second spring, causing the second spring to change from the natural stretching state to the taut state, which facilitates the limiting rod to return to its original position. When the second spring is in the natural stretching state, the limiting rod extends into the internal part of the limiting groove, realizing the fixation of the first annular disc and the cylinder, and preventing the rotating cylinder from affecting the fixation of the idler roller during the installation of the idler roller.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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.

[0027] Please refer to Figures 1 to 10 , a bending amount detection system for a roller, including a detection frame 1. A clamping mechanism 5 is arranged at the bottom between the two vertical plates of the detection frame 1. The clamping mechanism 5 includes a cylinder 51 for fixing the roller. After taking out the inner shaft of the roller, the cylinder 51 is inserted into the position of the roller shaft, effectively preventing the force application point from not being in the middle of the roller, and causing the bending deformation point of the roller to be located on both sides of the roller, resulting in difficulty in fixing the roller. The applicable range is wider. A detection mechanism 4 is arranged at the top between the two vertical plates of the detection frame 1. The detection mechanism 4 includes an adjusting plate 46 slidably connected to the opposite surfaces of the two vertical plates, a rotating disc 45 rotatably connected to the opposite surfaces of the two adjusting plates 46. Connecting rods 43 are fixedly connected to the opposite surfaces of the two rotating discs 45. A mounting rod 42 is fixedly connected between the two connecting rods 43. 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 roller, the contact point at this time is the reference point. Then move the dial indicator 3 so that the dial indicator 3 moves to the other side of the roller. During the movement, different positions of the roller are detected, so as to obtain the height difference between other position detection points and the reference point, and further obtain the bending degree of different positions of the roller. More detection values are obtained, and the applicable range is wider.

[0028] Such as Figures 1 to 10As shown in the figure, 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 the rotation of the mounting rod 42 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 end point of the pointer 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. 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. 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. 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. 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.

[0029] As Figures 1 to 10As shown in the figure, a lead screw 52 is rotatably connected inside a cylinder 51. Two driving plates 53 are helically driven and connected to the surface of the lead screw 52. The thread directions of the two driving plates 53 are opposite, which facilitates driving the relative movement of the driving plates 53 by rotating the lead screw 52. A pop-up block 531 is slidably connected inside the two driving plates 53. By moving the driving plates 53, the driving plates 53 can drive the pop-up block 531 to move. A transverse groove 511 for accommodating the movement of the pop-up block 531 is provided inside the cylinder 51 corresponding to the movement track of the pop-up block 531, so that the pop-up block 531 can leave the driving plate 53 and extend out from the transverse groove 511. When the pop-up block 531 reaches the outside of the cylinder 51, by moving the pop-up block 531 towards the middle of the cylinder 51, the roller on the surface of the cylinder 51 can be squeezed, so that the roller is located in the middle of the cylinder 51, which is convenient for detecting the roller. The end of the pop-up block 531 away from the driving plate 53 is arc-shaped. After the roller is in the middle of the cylinder 51, when the driving plate 53 continues to rotate under the lead screw 52, the driving plate 53 drives the pop-up block 531 to continue to move, and the pop-up block 531 is squeezed by the roller and returns to the inside of the driving plate 53. The driving plate 53 drives the pop-up block 531 to move towards the inside of the cylinder 51. A groove 532 is provided inside the driving plate 53 corresponding to the movement track of the pop-up block 531. The groove 532 facilitates the movement of the pop-up block 531 inside the driving plate 53, making the movement of the pop-up block 531 more convenient. A spring piece 533 is fixedly connected to the bottom of the groove 532. By moving the pop-up block 531 into the driving plate 53 and squeezing the spring piece 533, the spring piece 533 is deformed, which is convenient for the pop-up block 531 to return to its original position under the action of the spring piece 533. When the pop-up block 531 extends under the action of the spring piece 533, the pop-up block 531 can abut against the inner wall of the roller, making the axis of the roller coincide with the axis of the cylinder 51, which is more convenient for fixing the roller.

[0030] As Figures 1 to 10As shown, a cross plate 54 is fixedly connected to the side of the driving plate 53 close to the vertical plate of the detection frame 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, enabling the extension block 544 to drive the connecting block 542 to move inside the cross plate 54 and 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 upwards. Eventually, the first cross bar 541 is perpendicular to the cylinder 51. When the driving plate 53 drives the cross plate 54 towards the idler, the first cross bar 541 abuts against the idler, fixing the idler again, making the fixing of the idler more convenient 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 squeezes 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.

[0031] 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 to 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 disc 61 rotatably connected to the surface of the cylinder 51. By rotating the pressing disc 61, the pressing disc 61 rotates on the edge of the cylinder 51. A convex part 611 extends from the inside of the pressing disc 61 towards the center of the circle. When the pressing disc 61 rotates, the convex part 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 convex part 611, the inclined surface of the limiting rod 62 is pressed by the convex part 611, so that the limiting rod 62 moves under the extrusion. The limiting rod 62 moves towards the lead screw 52, and 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. When the lead screw 52 rotates, the cylinder 51 can be driven to rotate. When the lead screw 52 rotates while 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 disc 61, the limiting rod 62 presses the second spring 63, changing the second spring 63 from the natural stretching state to the taut state, which is convenient for the limiting rod 62 to return to its original position. A first annular disc 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 disc 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 disc 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.

[0032] A detection method for a bending amount detection system of an idler roller includes the following steps: S1: Installation. Take out the inner shaft of the idler roller, and 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 ejecting block 531 to be stuck into the inside of the idler roller, and the first cross bar 541 abuts against both sides of the idler roller. S2: Adjustment. Move the adjustment plate 46, the bottom of the correction rod 44 contacts both sides of the idler roller. Rotate the rotating disc 45, move the dial indicator 3 to the position of the correction groove 441, rotate the rotating disc 45, and the pointer of the dial indicator 3 is at the bottom of the correction groove 441. Then repeat the operation, and the pointer of the dial indicator 3 reaches the bottom of another correction groove 441. Compare the values of the dial indicator 3 at the bottoms of the two correction grooves 441, and then rotate the rotating disc 45 again, and the pointer of the dial indicator 3 points to the idler roller. S3: Detect. Rotate the extrusion disc 61, and the limit rod 62 is inserted into the lead screw 52. Rotate the lead screw 52 to drive the cylinder 51 to rotate. The rotation of the cylinder 51 drives the roller to rotate. Move the dial indicator 3, and the dial indicator 3 detects different positions of the rotating roller.
