Description

Technical Field

[0001] The invention belongs to the technical field of construction machinery detection equipment, and particularly relates to a wear detection device for track rollers of construction machinery. Background Art

[0002] As a construction machine, construction machinery is usually equipped with a driving mechanism for easy transfer. In order to be applicable to different working environments and ensure the passability of engineering vehicles, some construction machinery will choose tracks instead of tires. Construction machinery driven by tracks is equipped with a suspension system and a wheel set. The wheel set is divided into a driving wheel, a guide wheel, a carrier wheel and a track roller. Among them, the track rollers are distributed at the bottommost end and are responsible for bearing the overall weight of the construction machinery. Therefore, the track rollers are in a compressed state for a long time, resulting in inevitable wear of the track rollers, which in turn affects the overall drive system. Thus, the condition of the track rollers is related to the moving ability of construction machinery.

[0003] In order to master the wear condition of the track rollers, it is necessary to regularly detect and replace the track rollers, and replace the severely worn track rollers. During the detection process, it is necessary to move the construction machinery to a specific detection tooling position, or remove the track rollers from the suspension system for detection, resulting in a cumbersome detection process and interfering with the work of the construction machinery, and rapid detection cannot be achieved. Therefore, a portable detection device is needed to detect the wear of the track rollers of construction machinery without affecting the normal work of the construction machinery.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] As Figures 1 - 9 shown, this embodiment is used to detect the wear of the to-be-detected idler wheel 402 of construction machinery, and includes a lifting detection component 100, a hydraulic lifting component 200, and a moving track 300. The lifting detection component 100 is arranged on the hydraulic lifting component 200, the hydraulic lifting component 200 is arranged on the moving track 300, the hydraulic lifting component 200 is configured to control the lifting of the lifting detection component 100, the hydraulic lifting component 200 is slidably connected to the moving track 300, the to-be-detected idler wheel 402 is arranged on the suspension system 401 of the construction machinery vehicle body 400. When this embodiment is in use, the hydraulic lifting component 200 moves on the moving track 300, the hydraulic lifting component 200 drives the lifting detection component 100 to move to the position of the to-be-detected idler wheel 402, and then the hydraulic lifting component 200 drives the lifting detection component 100 to rise to contact the to-be-detected idler wheel 402, thereby pushing the to-be-detected idler wheel 402 to compress the suspension system 401, so that the suspension system 401 contracts, and the to-be-detected idler wheel 402 is lifted without moving the construction machinery vehicle body 400, so that the lifting detection component 100 can detect its wear.

[0022] In this embodiment, the lifting detection assembly 100 includes a detection plug 101 and detection rollers 102. A plurality of the detection rollers 102 are arranged on the detection plug 101, and the detection rollers 102 are fixedly connected to the detection plug 101. An elastic pressing strip 105 is circumferentially arranged on the curved surface of the detection roller 102, and the elastic pressing strip 105 is slidably and telescopically connected to the detection roller 102. The detection plug 101 can be used to lift the idler wheel 402 to be detected. The detection rollers 102 on the detection plug 101 are in direct contact with the idler wheel 402 to be detected. When the plurality of elastic pressing strips 105 arranged on the curved surface of the detection roller 102 come into contact with the idler wheel 402 to be detected, they are pressed down. When there is wear on the idler wheel 402 to be detected, there is a gap between the idler wheel 402 to be detected and the detection roller 102, resulting in the elastic pressing strip 105 not being pressed down, thereby determining whether there is a wear defect on the idler wheel 402 to be detected.

[0023] In this embodiment, a plurality of detection rollers 102 are arranged on the detection plug 101, and the central axes of the plurality of detection rollers 102 coincide with each other. When the idler wheel 402 to be detected is in a multi-layer stacked structure, by increasing the corresponding detection rollers 102, a comprehensive detection of the idler wheel 402 to be detected is ensured.

[0024] When this embodiment is in use, first, the hydraulic lifting assembly 200 on the moving track 300 slides towards the position of the idler wheel 402 to be detected. At this time, the lifting detection assembly 100 is in the lowest position. The hydraulic lifting assembly 200 drives the lifting detection assembly 100 to synchronously approach the idler wheel 402 to be detected. When the detection plug 101 moves between the idler wheel 402 to be detected and the traveling track 403, it is ensured that the detection rollers 102 and the idler wheel 402 to be detected are vertically corresponding. Subsequently, the hydraulic lifting assembly 200 drives the lifting detection assembly 100 to rise. During the rising process of the lifting detection assembly 100, the detection plug 101 and the detection rollers 102 apply an upward thrust to the idler wheel 402 to be detected, causing a single suspension system 401 to contract, and the idler wheel 402 to be detected is separated from the traveling track 403. At this time, the idler wheel 402 to be detected is in an active state and can rotate freely. Subsequently, the hydraulic lifting assembly 200 drives the detection plug 101 to rotate, and the detection plug 101 drives the detection rollers 102 to rotate synchronously. When the detection rollers 102 rotate, the elastic pressing strips 105 on the detection rollers 102 sequentially come into contact with the idler wheel 402 to be detected, thereby determining whether there is a wear defect on the idler wheel 402 to be detected according to the pressed state of the elastic pressing strips 105.

[0025] In this embodiment, the number of the detection insertion rods 101 is two. The axes of the two detection insertion rods 101 are located on the same horizontal plane, and the distance between the two detection insertion rods 101 is adjustable. During actual use, the two detection insertion rods 101 are respectively located on both sides of the to-be-detected idler wheel 402 and at the same height. When the detection insertion rods 101 rise, the same external force is applied to both sides of the to-be-detected idler wheel 402 to ensure the force balance of the to-be-detected idler wheel 402, thereby avoiding damage to the to-be-detected idler wheel 402, and the distance between the two detection insertion rods 101 can be adaptively adjusted according to the size of the to-be-detected idler wheel 402.

[0026] In this embodiment, by providing the lifting detection insertion rods 101 and the detection rollers 102, when the detection insertion rods 101 are inserted between the to-be-detected idler wheel 402 and the traveling track 403, the to-be-detected idler wheel 402 and the traveling track 403 can be separated without disassembling the to-be-detected idler wheel 402. At the same time, the elastic pressing strips 105 provided on the detection rollers 102 sequentially contact the to-be-detected idler wheel 402 when the detection rollers 102 rotate, and the surface wear condition of the to-be-detected idler wheel 402 is detected by judging the compression and expansion state of the elastic pressing strips 105.

[0027] In this embodiment, the hydraulic lifting assembly 200 includes a hydraulic jack 201 and an insertion rod support 203. A telescopic rod 202 is provided on the hydraulic jack 201. The telescopic rod 202 is slidably and telescopically connected to the hydraulic jack 201. The insertion rod support 203 is fixedly connected to the telescopic rod 202. The detection insertion rod 101 is provided on the insertion rod support 203. The detection insertion rod 101 and the insertion rod support 203 are rotatably connected. By providing the hydraulic jack 201 to drive the lifting of the detection assembly 100, a greater thrust can be provided to ensure that the to-be-detected idler wheel 402 and the traveling track 403 can be separated.

[0028] During the specific use of this embodiment, the hydraulic jack 201 drives the telescopic rod 202 to extend. The insertion rod support 203 on the telescopic rod 202 gradually rises, and at the same time, the detection insertion rod 101 on the insertion rod support 203 rises synchronously, finally realizing the lifting of the to-be-detected idler wheel 402.

[0029] In this embodiment, the hydraulic lifting assembly 200 further includes a driving motor 204. A motor support 206 is fixedly connected to the driving motor 204. The driving motor 204 is fixedly connected to the hydraulic lifting assembly 200 through the motor support 206. The output end of the driving motor 204 is connected to the detection insertion rod 101. The driving motor 204 is configured to drive the rotation of the detection insertion rod 101. By providing the driving motor 204 to drive the rotation of the detection insertion rod 101.

[0030] In the specific use of this embodiment, two driving motors 204 drive the two detection insertion rods 101 to rotate respectively. When the detection insertion rods 101 rotate, the detection rollers 102 on the detection insertion rods 101 drive the to-be-detected carrier wheels 402 to rotate. At the same time, the rotation directions of the two detection insertion rods 101 are set to be the same, so that the rotation directions of the detection rollers 102 on both sides of the to-be-detected carrier wheel 402 are the same, ensuring that the to-be-detected carrier wheel 402 can maintain a rotating state. As the detection rollers 102 rotate, the contact points between the detection rollers 102 and the to-be-detected carrier wheel 402 change, and the elastic pressing strip 105 can contact each surface of the to-be-detected carrier wheel 402, realizing a comprehensive detection of the wear state of the to-be-detected carrier wheel 402.

[0031] In this embodiment, the hydraulic lifting assembly 200 further includes a moving base 207. The hydraulic jack 201 and the motor support 206 are both fixedly arranged on the moving base 207. The bottom surface of the moving base 207 is slidably connected to the moving track 300. The sliding direction of the moving base 207 on the moving track 300 is parallel to the central axis of the detection insertion rod 101. The hydraulic jack 201, the driving motor 204 and the lifting detection assembly 100 are all integrated on the moving base 207. By moving the moving base 207, the movement of the lifting detection assembly 100 and the hydraulic lifting assembly 200 can be realized, facilitating the movement and transfer of this detection device and enabling rapid detection of multiple to-be-detected carrier wheels 402.

[0032] In the specific use of this embodiment, the moving track 300 is placed on the side of the engineering machinery vehicle body 400, and the direction of the moving track 300 points to the position of the to-be-detected carrier wheel 402. Subsequently, the lifting detection assembly 100 and the hydraulic lifting assembly 200 are moved together towards the to-be-detected carrier wheel 402 by moving the moving base 207. After the wear detection of the to-be-detected carrier wheel 402 is completed, the moving base 207 is moved back to its original position. Subsequently, the engineering machinery vehicle body 400 is started to move forward a short distance, so that the moving track 300 is aligned with the next to-be-detected carrier wheel 402, and then the next to-be-detected carrier wheel 402 can be detected. It is applicable to machinery with multiple to-be-detected carrier wheels 402, and can complete the wear degree detection of the to-be-detected carrier wheels 402 without disassembling the to-be-detected carrier wheels 402, and at the same time does not affect the normal working state of the engineering machinery vehicle body 400.

[0033] In this embodiment, the lifting detection assembly 100 further includes a distance-adjusting stop bar 103. The distance-adjusting stop bar 103 is arranged between adjacent detection rollers 102. Both ends of the distance-adjusting stop bar 103 abut against the end faces of adjacent detection rollers 102. The length of the distance-adjusting stop bar 103 is adjustable. By adjusting the length of the distance-adjusting stop bar 103, the distance between the detection rollers 102 can be adjusted, realizing different distribution states of the detection rollers 102 on the detection insertion rod 101.

[0034] When this embodiment is used in practice, for some rollers 402 to be detected that have a multi-layer structure, the gap width between each layer is first measured, and then the length of the adjustable baffle 103 is adjusted to the gap width, and then the adjustable baffle 103 is placed between adjacent detection rollers 102, so that the distance between adjacent detection rollers 102 is equal to the gap width of the rollers 402 to be detected, thereby achieving that the multi-layer structure of the rollers 402 to be detected are all in contact with the detection rollers 102, thereby improving the detection accuracy.

[0035] In this embodiment, an end chamfer 104 is provided on the end of the detection rod 101 away from the hydraulic lifting assembly 200. When the detection rod 101 moves toward the supporting wheel 402 to be detected, the end of the detection rod 101 will be inserted into the gap between the supporting wheel 402 to be detected and the walking track 403. By providing the end chamfer 104 on the end of the detection rod 101, it is ensured that the detection rod 101 can be smoothly inserted into the gap between the supporting wheel 402 to be detected and the walking track 403.

[0036] At the same time, an end chamfer 104 is provided on the end of the detection rod 101, which can increase the pressure at the end of the detection rod 101. When the detection rod 101 encounters obstacles such as sand and vegetation during its movement, it can smoothly penetrate the obstacles, thereby improving the puncture ability of the detection rod 101.

[0037] In this embodiment, an electronic control module 205 is provided on the drive motor 204, and the electronic control module 205 is electrically connected to the drive motor 204. The electronic control module 205 is configured to control the speed and direction of the drive motor 204, and the speed and direction of each drive motor 204 are adjusted through the electronic control module 205.

[0038] In actual use, for some to-be-detected rollers 402 with larger diameters, the rotation speed of the drive motor 204 can be adjusted specifically, and the rotation speed of the drive motor 204 can be reduced to output a larger torque, thereby ensuring that the drive motor 204 can drive the rotation of the detection roller 102 and the to-be-detected roller 402; conversely, for some to-be-detected rollers 402 with smaller diameters, the output torque of the drive motor 204 can be reduced accordingly to obtain a higher rotation speed, thereby making the detection roller 102 and the to-be-detected roller 402 rotate at a faster speed, thereby improving the detection efficiency.

[0039] In this embodiment, a piezoresistor is arranged between the elastic strip 105 and the detection roller 102, and the piezoresistors are connected to the current detection component. The piezoresistors and the current detection component are used to detect the pressure state of the elastic strip 105. The wear condition of the supporting wheel 402 to be detected can be determined by monitoring whether the readings of the current detection component are the same.

[0040] In the specific use of this embodiment, the detection roller 102 and the weight wheel 402 to be detected rotate, and the elastic pressing strips 105 on the detection roller 102 sequentially contact different positions of the weight wheel 402 to be detected; in the ideal state where there is no wear on the weight wheel 402 to be detected, since the axial distance between the detection roller 102 and the weight wheel 402 to be detected remains unchanged, the displacement of each elastic pressing strip 105 being pressed down is the same, so that the change amount of each piezoresistor is also the same. The result reflected on the current detection component is that the current on each piezoresistor is equal.

[0041] However, in actual situations, there is wear on the surface of the weight wheel 402 to be detected. With the axial distance between the detection roller 102 and the weight wheel 402 to be detected remaining unchanged, it will inevitably lead to the displacement of the elastic pressing strip 105 in contact with the worn position being different from that of other elastic pressing strips 105. The displacement amount of the elastic pressing strip 105 in contact with the worn position being pressed down will be smaller, resulting in a difference in the change amount of this piezoresistor compared to the change amounts of other piezoresistors. The result reflected on the current detection component is that the current of this piezoresistor is different from other currents, and thus it can be determined that there is wear on the weight wheel 402 to be detected.

[0042] At the same time, according to the magnitude of the difference between the currents in the current detection component, the degree of wear at the worn area can be judged. The greater the current difference, the greater the degree of wear, thus realizing the quantitative detection of the wear state.

[0043] In this embodiment, a rubber coating layer is provided on the elastic pressing strip 105. The rubber coating layer is located on the surface of the elastic pressing strip 105 away from the detection roller 102. Contact occurs between the rubber coating layer and the weight wheel 402 to be detected, which can play a buffering role and at the same time increase the friction force between the detection roller 102 and the weight wheel 402 to be detected, ensuring that the detection roller 102 can drive the weight wheel 402 to be detected to rotate.

[0044] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
