Description

Technical Field

[0001] This invention specifically relates to the field of conductive roller ring wear detection technology, and more specifically to a conductive roller ring wear detection device. Background Technology

[0002] With the increasing national demand for new energy sources, wind power has become a mainstream clean energy source. Conductive slip rings are a core component of wind turbines, responsible for transmitting electrical energy and signals between the rotating and stationary ends. Their performance directly affects the operational stability and operating costs of wind turbines. Traditional conductive slip rings use a sliding friction structure, which suffers from severe wear and high frictional losses over long-term operation, leading to unstable contact resistance, low transmission efficiency, short component lifespan, and frequent maintenance, failing to meet the long-term low-maintenance requirements of wind power generation. Existing technology has replaced conductive slip rings with conductive roller rings, significantly reducing frictional losses. However, critical parts of the roller ring still experience frictional losses over long-term operation, and the amount of wear directly affects conductivity stability and component lifespan. Currently, existing detection methods mostly rely on manual inspection or offline disassembly inspection, resulting in low detection efficiency and a lack of dedicated wear detection devices, making real-time quantitative detection impossible. Therefore, there is an urgent need for a matching wear detection device to ensure stable turbine operation. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned problems existing in the prior art and provide a conductive rolling ring wear detection device with high automation, accurate detection and real-time quantitative detection.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A conductive roller ring wear detection device includes a rotary drive mechanism, a wear detection mechanism, a control and processing system, and a frame assembly.

[0006] Both the rotary drive mechanism and the wear detection mechanism are mounted on the frame assembly.

[0007] The control and processing system issues control commands, which are then driven by the frame assembly to rotate. Simultaneously, the wear detection mechanism forms a tight contact with the conductive rolling ring under test. The wear detection mechanism collects wear data and feeds it back to the control and processing system, which then integrates the data and outputs the results.

[0008] Furthermore, as a preferred embodiment, the rotary drive mechanism includes a drive motor, a drive shaft, and a belt drive mechanism. The drive motor is mounted on a support pedestal of the frame assembly, and the drive shaft is connected to the output end of the drive motor via a coupling or a belt drive mechanism.

[0009] Furthermore, as a preferred embodiment, the belt drive mechanism includes a driving pulley, a driven pulley, and a synchronous drive belt. The driving pulley is connected to the output shaft of the drive motor, and the driven pulley is connected to the drive shaft. The driving pulley drives the driven pulley via the drive belt, causing the three-jaw chuck to work together. The drive belt is usually a synchronous belt, and the grooves of both the large and small pulleys match the tooth profile of the drive belt.

[0010] Furthermore, as a preferred embodiment, the three-jaw chuck is a self-centering chuck, where the jaws can move synchronously along the radial direction to achieve centering and clamping of conductive rolling rings of different models.

[0011] Furthermore, preferably, the wear detection mechanism includes a linear slide rail, a detection ring plate, and a detection device connected to the outside of the detection ring plate. The detection device, controlled by a control processing system, drives a detection contact to move radially, thereby contacting the conductive roller ring and detecting the degree and amount of wear. The detection ring plate, through a slider cooperating with the linear slide rail, can slide horizontally along the worktable surface and can be disassembled and replaced according to different workpiece specifications. The linear slide rail is supported on the worktable surface by a frame assembly.

[0012] Furthermore, as a preferred embodiment, the detection device includes a detection contact, a lead screw assembly (207), a guide assembly (208), and a contour replication ring. The detection contact moves radially under the drive of the lead screw assembly (207), and the contour replication ring is mounted on the rear ring plate of the detection ring plate for contacting the outer ring of the conductive rolling ring to be tested and replicating its wear contour.

[0013] Furthermore, as a preferred embodiment, the detection contact is coupled with the contour replication ring to detect the displacement change of the contour replication ring caused by the wear of the conductive roller ring. The detection head is provided with an elastic buffer structure and a displacement detector. The displacement detector is used to collect the radial displacement signal of the detection head to characterize the wear amount of the conductive roller ring.

[0014] Furthermore, preferably, the control processing system is used to receive displacement data from multiple detection devices and process the data to generate a circumferential wear distribution curve of the conductive rolling ring.

[0015] Furthermore, as a preferred embodiment, the control and processing system includes a cabinet installed on the right side of the workbench and a control laptop installed on the front of the workbench. These components establish signal connections with the rotary drive mechanism and the wear detection mechanism via a communication interface, enabling data transmission and integration to form a closed-loop feedback.

[0016] Furthermore, as a preferred embodiment, the cabinet support legs are adjustable to ensure the cabinet's horizontal height and stability, and the support legs provide horizontal shock absorption when in contact with the ground. The left side of the cabinet door has a heat dissipation assembly composed of annular ventilation holes, which form a convection airflow channel to achieve convection cooling under high-temperature conditions.

[0017] Compared with existing technologies, the present invention, employing the above-mentioned technical solution, has the following beneficial effects: Through a multi-point detection structure, it achieves comprehensive acquisition of the wear amount of the conductive rolling ring, improving detection accuracy; through a rotary drive mechanism, it achieves automated detection, improving detection efficiency; through a control processing system, it processes multi-point data to generate wear distribution curves, enabling visual analysis of the wear state; through a self-centering chuck structure, it improves the clamping adaptability of rolling rings of different specifications; through a movable detection ring plate structure, it improves the adaptability and flexibility of the equipment; through a protective structure, it improves the safety of the detection process; through a contour replication structure, it achieves real-time replication of the wear contour of the outer ring of the conductive rolling ring, and combines this with indirect measurement using detection contacts, constructing a "contour replication—displacement detection" detection path, avoiding errors caused by direct contact detection, and improving the stability, repeatability, and measurement accuracy of the detection process; through an integrated closed-loop feedback structure, it effectively reduces labor and time costs, reduces detection errors, significantly improves wear detection efficiency, overcomes the shortcomings of existing technologies in comprehensively assessing the wear state, and achieves efficient, accurate, and visual detection of the wear amount of the conductive rolling ring. The rotary drive mechanism, wear detection mechanism, and control processing system are installed on the frame assembly respectively. Each mechanism has an independent structure and a clear function, which not only facilitates the assembly and debugging of the whole machine, but also makes it easier for later inspection and maintenance.

[0024] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, this embodiment provides a conductive roller ring wear detection device, including a rotary drive mechanism, a wear detection mechanism, a control and processing system, and a frame assembly.

[0026] The rotary drive mechanism is mounted on the frame assembly and includes a drive motor, a drive shaft, and a belt drive mechanism. The drive motor drives the drive shaft to rotate via a synchronous belt. A self-centering three-jaw chuck is set at the front end of the drive shaft to hold the conductive rolling ring.

[0027] The wear detection mechanism includes a linear slide and a detection ring plate. The detection ring plate is mounted on the linear slide via a slider and can move axially to accommodate conductive rolling rings of different sizes. Multiple detection devices are evenly arranged circumferentially on the detection ring plate.

[0028] Each detection device includes a lead screw assembly (207), a guide assembly (208), and a detection contact, which moves radially under the drive of the lead screw and maintains stable motion under the constraint of the guide assembly.

[0029] The detection contact indirectly obtains the wear profile change of the conductive rolling ring by cooperating with the profile replication ring. Its displacement is collected by the displacement detector and the displacement signal is transmitted to the control processing system.

[0030] The control and processing system processes the displacement data from multiple detection points and generates a circumferential wear distribution curve for the conductive rolling ring through a fitting algorithm, thereby achieving a quantitative assessment of the wear amount.

[0031] A protective cover is installed on the outside of the equipment to isolate the testing area, improve operational safety, and facilitate observation of the testing process.
