Description

Technical Field

[0001] The invention relates to the technical field of vibration detection, in particular to a vibration detector for a bulldozer shaft and a detection method thereof. Background Art

[0002] The dynamic balancing of the press shaft refers to measuring the vibration condition of the press shaft during rotation, finding the distance difference between the centrifugal force center of the press shaft and the axis of rotation, thereby determining the dynamic balance state of the press shaft and ensuring its stability and safety during operation.

[0003] Before making dynamic balance corrections, the final shaft needs to be tested for balance to determine its initial state. After completing the final shaft balance test, dynamic balance corrections can be made based on the test results. After completing the final shaft dynamic balance corrections, another test is required to confirm the correction effect.

[0004] The existing dynamic balancing test generally installs the final shaft on a test seat, controls the rotation of the final shaft through the test seat, and records the vibration amplitude of the final shaft during rotation. Through data analysis, the static balance state of the final shaft is determined, that is, the distance between the centrifugal force center and the axis of the final shaft is found. However, due to the different scenarios in which the final shaft is used, the required rotation speed is also different. The existing test generally only tests at the same speed, resulting in inaccurate final shaft test results. Summary of the invention

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0042] See also Figure 1 to Figure 10In an embodiment of the present invention, a vibration detector for a bulldozer shaft includes: a truss 1, a lifting plate 2, an elastic clamping assembly, a card plate 30, a driving mechanism, a vibration detection mechanism, a detection ring 31, a sensor 32, and a speed control mechanism. In order to ensure the accuracy of the shaft detection, it is necessary to control the shaft to perform vibration detection at different speeds. Therefore, during the detection, the shaft can be placed between the card plates 30 and pass through the detection ring 31. Under the action of the card plates 30, the shaft is located at the center of the detection ring 31 when it is not rotating. Due to the uneven mass distribution of the shaft, different parts are subjected to different centrifugal forces when it rotates. Therefore, when the driving mechanism is working, the card plate 30 is driven to move through the speed control mechanism to drive the shaft to rotate. When the shaft rotates, the centrifugal force is increased. During the process, vibration will occur, and the sensor 32 will record the amplitude of the vibration. At the same time, the driving mechanism will also drive the vibration detection mechanism to move, so that the detection ring 31 moves along the length direction of the press shaft, and the press shaft is comprehensively detected by the sensor 32. The vibration detection mechanism will also drive the speed control mechanism to move, and after the detection ring 31 moves to the end of the stroke on one side of the press shaft, the speed of the elastic clamping assembly is adjusted by the speed control mechanism and the driving mechanism to increase the speed of the press shaft. As the speed of the press shaft increases, its vibration amplitude will also increase. Under the action of the vibration detection mechanism, the detection ring 31 is controlled to move toward the initial position to measure the vibration amplitude of the press shaft at different speeds. The above steps are repeated to obtain accurate data for the vibration detection of the press shaft.

[0043] The details are as follows, including:

[0044] A truss 1, and a lifting plate 2 fixedly mounted on the truss 1 and symmetrically arranged;

[0045] Also includes:

[0046] See also Figure 1-Figure 3 , Figure 6 , Fig. 9 , Fig.10 , an elastic clamping assembly is arranged on the lifting plate 2, and a plurality of clamping plates 30 equidistantly distributed around the circumference are connected to the elastic clamping assembly, and the clamping plates 30 are used to clamp the pressure shaft, and the elastic clamping assembly includes a rotating sleeve 25 rotatably mounted on the lifting plate 2, a cross plate 26 is fixed to the end of the rotating sleeve 25, and a plurality of hollow rods 27 equidistantly distributed around the circumference are fixed to the cross plate 26, a support rod 28 is movably mounted in the hollow rod 27, and the support rod 28 is fixedly connected to the clamping plate 30, and a spring 29 abutting against the clamping plate 30 is sleeved on the hollow rod 27 and the support rod 28.

[0047] In detail, due to the uneven mass distribution of the press shaft, vibration will occur when the press shaft rotates. Therefore, it is necessary to ensure that the jumping of the press shaft is not restricted during clamping to ensure the accuracy of the detection. In the initial state, the spring 29 is in a compressed state, so that the support rod 28 is located at the end of the stroke away from the hollow rod 27 to minimize the distance between the card plates 30. When the press shaft needs to be detected, the card plates 30 can be controlled to move in a direction away from each other, and the press shaft can be placed between the card plates 30. When the placement is completed, the spring 29 is elastically released, and the card plates 30 are controlled to fit with the press shaft through the support rod 28, thereby fixing the press shaft.

[0048] Preferably, since the spacing between the clamps 30 is adjustable, the clamps of different sizes can be clamped, thereby increasing the applicability of the device. When the clamp rotates and vibrates, the clamps 30 can move with the clamp under the action of the spring 29 to ensure the accuracy of the detection.

[0049] See also Figure 1-Figure 5 , Figure 7 The lifting plate 2 is also provided with a driving mechanism connected with the elastic clamping assembly, and the driving mechanism can drive the clamping plate 30 to move through the elastic clamping assembly to control the rotation of the pressure shaft, and the driving mechanism includes a transmission rod 4 rotatably mounted on the lifting plate 2, and the transmission rod 4 is connected with the output shaft of the motor 3 fixedly mounted on the lifting plate 2; and also includes a follower cone 15 fixedly mounted on the transmission rod 4, a sliding sleeve 17 is movably mounted on the transmission rod 4, and a movable cone 18 is fixed on the sliding sleeve 17, and a plurality of card slots 16 equidistantly distributed on the circumference of the follower cone 15 and the movable cone 18 are provided, and a driven assembly connected with the rotating sleeve 25 is arranged in the card slot 16, wherein the driven assembly includes a support column 19 slidably mounted in the card slot 16, and an arc plate 20 is fixed on the end of the support column 19 away from the card slot 16, and a belt 21 rotatably connected with the rotating sleeve 25 is sleeved on the arc plate 20.

[0050] It should be noted that when the pressure shaft is tested, it is necessary to control the rotation of the pressure shaft to measure its vibration amplitude. When the pressure shaft is fixed between the clamping plates 30, the motor 3 works and drives the transmission rod 4 to rotate, thereby driving the follower cone 15 to rotate. The follower cone 15 will control the movement of the support column 19 through the clamping groove 16, thereby driving the arc plate 20 to move. Under the action of the arc plate 20, the movable cone 18 is controlled to rotate synchronously through the support column 19 and the clamping groove 16. The arc plate 20 will also drive the rotating sleeve 25 to rotate through the belt 21, thereby controlling the rotation of the pressure shaft through the clamping plate 30.

[0051] Preferably, if the mass distribution of the pressure shaft is relatively uniform, the vibration amplitude is not obvious. Therefore, different rotation speeds need to be applied to the pressure shaft to ensure the accuracy of the detection. In the initial state, the distance between the follower cone disk 15 and the movable cone disk 18 is the largest, so that the support column 19 is located at the end of the stroke on one side of the slot 16, so that the distance between the arc plates 20 is minimized. At this time, the rotation speed of the rotating sleeve 25 remains unchanged. If the rotation speed needs to be increased, under the action of the speed control mechanism, the sliding sleeve 17 is controlled to move toward the follower cone disk 15, so that the distance between the follower cone disk 15 and the movable cone disk 18 is reduced, thereby controlling the support column 19 to move along the length direction of the slot 16 to increase the distance between the arc plates 20. Since the belt 21 can be stretched or contracted to a certain extent, the belt 21 will be stretched. At this time, the transmission ratio between the arc plate 20 and the rotating sleeve 25 changes, thereby increasing the rotation speed of the rotating sleeve 25.

[0052] See also Figure 1-Figure 3 , Figure 5 , Figure 7 , Figure 8 , a vibration detection mechanism is arranged on the lifting plate 2 and connected to the driving mechanism, a detection ring 31 is connected to the vibration detection mechanism, a plurality of sensors 32 are fixed to the circumferential inner wall of the detection ring 31, the pressing shaft passes through the detection ring 31, and the vibration detection mechanism can control the detection ring 31 to move along the length direction of the pressing shaft when the driving mechanism moves, and the vibration detection mechanism includes a first spiral groove 5, a second spiral groove 6, and an annular groove 7 provided on the transmission rod 4, the first spiral groove 5 and the second spiral groove 6 are cross-arranged, and the annular groove 7 is symmetrical It is provided that a translation assembly is provided on the lifting plate 2, wherein the translation assembly includes a rotating rod 8 rotatably mounted on the lifting plate 2, a supporting sleeve 9 movably mounted on the rotating rod 8, a diamond block 10 rotatably mounted on the side wall of the supporting sleeve 9, and the diamond block 10 can be slidably connected along the first spiral groove 5, the second spiral groove 6 and the annular groove 7; it also includes a guide rod 22 fixedly mounted on the lifting plate 2, a No. 1 guide sleeve 23 slidably mounted on the guide rod 22, and the No. 1 guide sleeve 23 is fixedly connected to the supporting sleeve 9 and the detection ring 31.

[0053] Furthermore, the first spiral groove 5 and the second spiral groove 6 are opened in a bolt shape, and the starting surface of the first spiral groove 5 and the second spiral groove 6 are the same, and the end surface is also the same, but the opening angles differ by 180°, and the spiral directions are opposite, so that the first spiral groove 5 and the second spiral groove 6 are arranged in a cross shape, and the annular groove 7 is symmetrically arranged, and is connected with the starting point and the end point of the first spiral groove 5 and the second spiral groove 6 respectively, and the diamond block 10 is arranged in a diamond shape. In the initial state, the support sleeve 9 is located at the end of the stroke on one side of the transmission rod 4, and the diamond block 10 is located at the connection position of one of the annular grooves 7 and the first spiral groove 5. The detection ring 31 is located at the end of the stroke on one side of the pressure shaft. When the pressure shaft needs to be detected, at this time, the transmission rod 4 rotates, driving the first spiral groove 5, the second spiral groove 6 and the annular groove 7 to move, and the diamond block 10 will disengage from the annular groove 7 and enter the first spiral groove 5, so that the support sleeve 9 is located at the end of the stroke on one side of the transmission rod 4. The sleeve 9 moves, thereby driving the detection ring 31 to move along the length direction of the pressure shaft. Under the action of the sensor 32, the vibration generated when the pressure shaft rotates is detected. The support sleeve 9 will also drive the No. 1 guide sleeve 23 to move along the length direction of the guide rod 22. The No. 1 guide sleeve 23 and the guide rod 22 have a guiding function to ensure that the support sleeve 9 moves along the length direction of the rotating rod 8 without deflection. When the diamond block 10 moves to the connection position between the first spiral groove 5 and the other annular groove 7, the support sleeve 9 moves to the end of the stroke, and the transmission rod 4 continues to rotate, so that the diamond block 10 slides along the annular groove 7 and enters the second spiral groove 6, so that the support sleeve 9 moves toward the initial position, thereby controlling the detection ring 31 to detect again along the length direction of the pressure shaft until the diamond block 10 returns to the initial position, and repeats the above steps to fully detect the pressure shaft.

[0054] Preferably, since the diamond block 10 is arranged in a diamond shape, it can be ensured that when the diamond block 10 moves along the trajectory of the first spiral groove 5 or the second spiral groove 6, when it moves to the intersection of the first spiral groove 5 and the second spiral groove 6, the diamond block 10 always moves along the trajectory of the first spiral groove 5 or the second spiral groove 6, and will not enter the other spiral groove through the intersection. Among them, the sensor 32 is a distance sensor, which can detect the distance from the sensor 32 to the pressure shaft. If the pressure shaft vibrates, the distance between the sensor 32 and the pressure shaft changes, thereby realizing the detection of the vibration amplitude. This is an application of the prior art and will not be elaborated in this application.

[0055] See also Figure 1-Figure 3 , Figure 5 , Figure 7 , Figure 8, a speed control mechanism is arranged on the vibration detection mechanism and connected to the driving mechanism. The speed control mechanism can adjust the speed of the elastic clamping assembly through the driving mechanism when the vibration detection mechanism moves. The speed control mechanism includes a first straight groove 801, a first inclined groove 802, a second straight groove 803, and a second inclined groove 804 that are symmetrically arranged on the rotating rod 8. A No. 1 limit block 11 is fixed to the inner wall of the supporting sleeve 9. The No. 1 limit block 11 is connected to the first straight groove 801, the first inclined groove 802, the second straight groove 803, and the second inclined groove 80 4 sliding connection, the rotating rod 8 is provided with a guide assembly connected with the sliding sleeve 17, wherein the guide assembly includes a guide groove 805 opened on the rotating rod 8, a movable sleeve 12 is movably mounted on the rotating rod 8, a second limit block 13 slidably connected with the guide groove 805 is fixed in the movable sleeve 12, a movable plate 14 rotatably connected with the sliding sleeve 17 is fixed on the side wall of the movable sleeve 12, and the guide assembly also includes a second guide sleeve 24 slidably mounted on the guide rod 22, and the second guide sleeve 24 is fixedly connected with the movable sleeve 12.

[0056] Furthermore, the first inclined groove 802 and the second inclined groove 804 are arranged in a spiral shape, and the pitch is equal, the number of spiral turns is a quarter turn, the two ends of the first inclined groove 802 are respectively connected to one end of the first straight groove 801 and the second straight groove 803, and the two ends of the second inclined groove 804 are respectively connected to the other end of the first straight groove 801 and the second straight groove 803, and the guide groove 805 is arranged in a ring shape and spirally. In the initial state, the No. 1 limit block 11 is located at the connection position between the first straight groove 801 and the second inclined groove 804, and the No. 2 limit block 13 is located at the end of the stroke on one side of the guide groove 805. When the transmission rod 4 rotates, the control support sleeve 9 moves along the length direction of the rotating rod 8, so that the No. 1 limit block 11 moves along the length direction of the first straight groove 801. At this time, the rotating rod 8 will not rotate. When the No. 1 limit block 11 moves to the connection between the first straight groove 801 and the first inclined groove 802 When the first limit block 11 is in the open position, the first limit block 11 will enter the first inclined groove 802, causing the rotating rod 8 to rotate. When the first limit block 11 moves to the connecting position of the first inclined groove 802 and the second straight groove 803, the rotating rod 8 rotates a quarter of a turn, the supporting sleeve 9 moves to the end of the stroke, and the detection ring 31 moves to the end of the stroke on one side of the pressure shaft. When the rotating rod 8 rotates, it will also drive the guide groove 805 to move. Under the action of the guide groove 805, the movable sleeve 12 fixed with the second limit block 13 moves, so that the second guide sleeve 24 moves along the length direction of the guide rod 22, ensuring that the movable sleeve 12 will not deflect during movement. The movable sleeve 12 will also drive the movable plate 14 to move, so as to drive the sliding sleeve 17 to move along the length direction of the transmission rod 4 and move toward the follower cone 15, so that the spacing between the arc plates 20 increases, thereby increasing the rotation speed of the rotating sleeve 25.

[0057] Preferably, the transmission rod 4 continues to rotate, so that the support sleeve 9 moves toward the initial position, so that the No. 1 limit block 11 moves along the length direction of the second straight groove 803. When the No. 1 limit block 11 moves to the connection position between the second straight groove 803 and the second inclined groove 804, the No. 1 limit block 11 enters the second inclined groove 804, so that the rotating rod 8 rotates until the No. 1 limit block 11 moves to the connection position between the second inclined groove 804 and the first straight groove 801, and the rotating rod 8 rotates a quarter of a turn again, thereby controlling the movable sleeve 12 to continue to move through the guide groove 805 and the No. 2 limit block 13, so that the spacing between the movable cone disk 18 and the follower cone disk 15 is reduced again, thereby increasing the spacing between the arc plates 20, so that the rotation speed of the rotating sleeve 25 is increased, so that the rotation speed of the pressure shaft is increased, thereby further increasing the accuracy of detection.

[0058] Among them, at this time, the second limit block 13 moves to the end of the stroke on the other side of the guide groove 805, and the rotation speed of the rotating sleeve 25 reaches the maximum. When the transmission rod 4 continues to rotate, the control detection ring 31 detects the pressure shaft when the pressure shaft rotation speed is the maximum. After the detection of the detection ring 31 is completed, under the action of the first limit block 11 and the first inclined groove 802, the rotating rod 8 is rotated another quarter of a turn, and under the action of the guide groove 805 and the second limit block 13, the movable sleeve 12 moves toward the initial position to increase the spacing between the follower cone disc 15 and the movable cone disc 18, thereby reducing the rotation speed of the rotating sleeve 25, and repeat the above steps until the rotation speed of the rotating sleeve 25 returns to the initial state and the rotating rod 8 rotates one circle. At this time, the detection of the pressure shaft is completed.

[0059] A detection method of a vibration detector for a bulldozer shaft comprises the following steps:

[0060] Step 1: insert the pressure shaft to be tested between the clamping plates 30 and pass through the detection ring 31. Under the action of the elastic clamping assembly, the pressure shaft is fixed by the clamping plates 30;

[0061] Step 2: Under the action of the driving mechanism, the elastic clamping assembly is driven to move, so as to control the rotation of the pressing shaft through the clamping plate 30. At the same time, the driving mechanism also drives the vibration detection mechanism to move, so as to drive the detection ring 31 to move along the length direction of the pressing shaft. Under the action of the sensor 32, the vibration generated when the pressing shaft rotates is detected;

[0062] Step 3: When the detection ring 31 moves to the end of the stroke, the vibration detection mechanism drives the speed control mechanism to move to adjust the speed of the elastic clamping assembly, thereby increasing the speed of the pressing shaft;

[0063] Step 4: After the detection is completed, the pressing shaft can be taken out from the clamping plate 30.
