Description

Technical Field

[0001] This utility model relates to the field of roller repair technology, specifically to an online repair auxiliary support and repair device. Background Technology

[0002] In industrial production, support rollers, as key support components of heavy equipment (such as rotary kilns and dryers), bear heavy loads and friction for extended periods, making them prone to wear, scratches, and uneven surfaces, which affect the stability and safety of equipment operation. Traditional support roller repair methods usually require disassembling the rollers and transporting them to a repair shop for processing. This method is not only time-consuming and labor-intensive, but also leads to prolonged equipment downtime, resulting in significant production losses.

[0003] To improve maintenance efficiency, current repair methods have incorporated online repair technology, which enables the repair of support rollers during continuous operation or short-term shutdowns. For example, patent CN110774132A discloses a device for online dynamic repair of rotary kiln support rollers. This device includes: a sliding guide rail, a power motor, a support frame, a sanding belt, and a machine frame. The sliding guide rail is located on the top of the machine frame, and the power motor is fixed to the sliding guide rail and can reciprocate along it. A drive wheel is fixed to the rotating shaft of the power motor, and a support frame is fixed to the motor's housing. A driven wheel is shafted onto the support frame, and a sanding belt is fitted onto both the drive wheel and the driven wheel. The sanding belt can contact the rotary kiln support rollers. This device can perform online dynamic repair of the support rollers and tires during rotary kiln operation.

[0004] However, existing online repair equipment often has limited functionality, mainly focusing on the repair operation itself. In actual repair processes, precise inspection of the support roller is required before and after repair. Existing technologies require the use of separate inspection and repair equipment, resulting in cumbersome disassembly and reassembly, and difficulty in ensuring consistency between the inspection and repair benchmarks, thus affecting repair accuracy and efficiency.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problems of limited functionality in online repair equipment, the separation of detection and repair operations leading to cumbersome disassembly and reassembly, and the difficulty in ensuring consistency between detection and repair benchmarks, this invention provides an online repair auxiliary support and repair device that integrates detection and repair functions and allows for rapid switching of operating modes. This support, through a rotatable mounting mechanism and multiple functional stations arranged circumferentially, achieves integrated automated detection and repair of the same equipment or component, significantly improving repair efficiency and accuracy.

[0021] It should be noted that the online repair auxiliary support and repair device described in this utility model are used for, but not limited to, support roller repair. For ease of explanation, this utility model only uses the application of the online repair auxiliary support and repair device to support roller repair as an example. The principle of the online repair auxiliary support and repair device in the repair of other types of rotating bodies is essentially the same as that in the repair of support rollers, and will not be described in detail here.

[0022] Please see Figures 1 to 4 In a first aspect, embodiments of this application provide an online repair auxiliary support, including a mounting body 1, a rotating mounting mechanism 2, and a detection structure 3. The rotating mounting mechanism 2 is rotatably mounted on the mounting body 1. Multiple mounting stations are arranged circumferentially along its rotation axis on the rotating mounting mechanism 2, including at least one detection mounting station and at least one repair mounting station. The repair mounting station is configured for mounting repair tools, and the rotating mounting mechanism 2 is configured to switch between different mounting stations corresponding to the position to be repaired when rotating around its rotation axis. The detection structure 3 includes multiple detection elements respectively disposed on each detection mounting station.

[0023] In this device, by setting up a rotating mounting mechanism 2 and multiple circumferentially arranged mounting stations, the detection and repair tools can be quickly switched on the same device. The detection structure 3 is equipped with multiple detection components, enabling real-time detection of the surface condition of the support roller before, during, and after repair, obtaining accurate data to provide a basis for the repair operation. Both the detection components and the repair tools are mounted on the rotating mounting mechanism 2, which can rotate around its axis, flexibly switching between different stations corresponding to the repair position. This ensures the consistency of the positioning reference, effectively avoiding errors caused by multiple clamping operations, and significantly improving repair accuracy and reliability. This online repair method avoids the need to disassemble the support roller, greatly shortening equipment downtime and reducing production losses and maintenance costs.

[0024] Among them, the main installation body 1 serves as the supporting foundation for the entire device and can be a plate type, frame type, column type, or other mechanical structure suitable for fixed installation. Its specific form can be adjusted according to the actual application scenario.

[0025] Please see Figures 1 to 4 In some possible embodiments, the rotary mounting mechanism 2 is rotatably mounted on the mounting body 1 via a rotary support or bearing. The rotary mounting mechanism 2 includes a disc-shaped mounting platform 21 and several mounting plates 22. Multiple mounting portions are evenly distributed circumferentially along the axis of rotation on the mounting platform 21, and each mounting portion is detachably connected to a mounting plate 22 via bolts. The multiple mounting plates 22 together constitute multiple mounting stations, including at least one inspection mounting station and at least one repair mounting station, used to respectively support the inspection component and the repair tool.

[0026] To drive the rotary mounting mechanism 2 to rotate automatically, please refer to [link / reference]. Figure 1 In some possible embodiments, the online repair auxiliary support also includes a rotary drive structure 4, which is connected to the rotary mounting mechanism 2 and is used to drive the rotary mounting mechanism 2 to rotate so as to switch different mounting positions to correspond to the position to be repaired.

[0027] Please see Figure 1 and Figure 5 In some possible embodiments, the rotary drive structure 4 includes a rotary drive motor 41 and a gear transmission mechanism 42. The rotary drive motor 41 is fixed to the mounting body 1, and its output shaft is connected to the driving gear 421 via a coupling. The gear transmission mechanism 42 consists of a meshing driving gear 421 and a driven gear 422, with the driven gear 422 coaxially fixed to the rotary mounting mechanism 2. After receiving a control signal, the rotary drive motor 41 precisely drives the mounting platform 21 to rotate a specific angle through the gear pair, thereby achieving precise switching of workstations.

[0028] Of course, please see Figures 1 to 7In some other possible embodiments, the rotation of the rotating mounting mechanism 2 can also be achieved by manual rotation. In this case, the position of the rotating mounting mechanism 2 can be manually determined and fixed by the cooperation of the positioning pin 52 and the positioning hole 51. To ensure the positioning accuracy after rotation stops, in some possible embodiments, the bracket is also provided with a positioning structure 5. The positioning structure 5 includes multiple positioning holes 51 provided on the mounting body 1 and positioning pins 52 provided on the rotating mounting mechanism 2. When the mounting platform 21 rotates to the target position and is aligned, the positioning pins 52 can be inserted into the corresponding positioning holes 51, thereby eliminating transmission gaps and ensuring the stability of the tool during operation.

[0029] Furthermore, to improve the stability of the locating pin 52 after it is inserted into the locating hole 51, the locating pin 52 is provided with threads that are compatible with the threads on the inner wall of the locating hole 51. When the locating pin 52 is inserted into the locating hole 51, the two are tightly connected by the threads, which enhances the bonding force between the locating pin 52 and the locating hole 51 and effectively prevents the locating pin 52 from loosening or shifting due to external forces during operation.

[0030] Of course, in some other possible embodiments, the positioning structure 5 and the rotary drive structure 4 can coexist. In this case, the positioning structure 5 and the rotary drive structure 4 cooperate with each other to ensure the stable operation and precise operation of the online repair auxiliary support. The positioning structure 5 ensures that the rotary mounting mechanism 2 can be accurately positioned after it stops rotating through the tight cooperation of the positioning pin 52 and the positioning hole 51, while the rotary drive structure 4 realizes the automatic rotation and station switching of the rotary mounting mechanism 2 through the motor and gear transmission mechanism 42.

[0031] To expand the adjustment range and flexibility of the repair device, please refer to Figure 1 In some possible embodiments, the online repair auxiliary support also includes a linear drive structure 6, which is connected to the rotary mounting mechanism 2 and is used to drive the rotary mounting mechanism 2 to move in a linear direction to adjust the position of the rotary mounting mechanism 2 relative to the device to be repaired.

[0032] Please see Figures 1 to 5In some possible embodiments, the linear drive structure 6 includes a linear screw guide rail, comprising a servo motor 61, a linear guide rail 63, a ball screw 62, and a sliding frame 64. The servo motor 61 is fixed to the mounting body 1, and its output shaft is connected to the ball screw 62 via a coupling. The ball screw 62 is arranged parallel to the linear guide rail 63. The sliding frame 64 is sleeved on the ball screw 62 and the linear guide rail 63, threadedly engaging with the ball screw and slidably engaging with the linear guide rail 63. The rotary mounting mechanism 2 is fixed on the sliding frame 64. The servo motor 61 drives the ball screw 62 to rotate, thereby causing the sliding frame 64 to move linearly along the linear guide rail 63, achieving precise movement of the rotary mounting mechanism 2 in the linear direction. Through the linear drive structure 6, the position of the rotary mounting mechanism 2 can be flexibly adjusted according to the specific location of the device to be repaired and the repair requirements, enabling the repair tools and inspection parts to be more accurately aligned with the parts to be repaired, further improving the accuracy and efficiency of the repair. Meanwhile, the linear drive structure 6 and the rotary mounting mechanism 2 work together to provide multi-dimensional adjustment capabilities for the online repair auxiliary support, enabling it to adapt to repair tasks in different scenarios.

[0033] Detection structure 3 includes multiple detection components. Please refer to [link / reference]. Figures 1 to 4 In some possible embodiments, the detection components are a laser displacement sensor 31 and a vision inspection device 32. The laser displacement sensor 31 is fixedly mounted on the mounting plate 22 of one of the inspection and installation stations, and is used for non-contact, high-precision detection of displacement data such as surface wear and unevenness of the support roller. The vision inspection device 32 uses a camera or other imaging device, and is fixedly mounted on the mounting plate 22 of another inspection and installation station, to acquire high-definition image information of the support roller surface for defect identification and location.

[0034] In some possible embodiments, a repair tool, such as a grinding tool 7 or a turning tool 8, is mounted on the mounting plate 22 of the repair installation station. The rotary mounting mechanism 2 can rotate about its axis, thereby quickly switching the required inspection piece or repair tool to the working position, realizing continuous inspection and repair operations on the workpiece.

[0035] Preferably, please refer to Figures 1 to 4In this embodiment, there are four mounting plates 22. Two mounting plates 22 are respectively equipped with a laser displacement sensor 31 and a vision inspection device 32, while the other two mounting plates 22 are respectively equipped with a grinding tool 7 and a turning tool 8. The four mounting plates 22 are evenly distributed on the disc-shaped mounting table 21 of the rotary mounting mechanism 2. Correspondingly, every time the mounting table 21 rotates 45°, the work position can be switched and positioned by the rotary drive structure 4 or the positioning structure 5, ensuring that it can accurately correspond to the preset detection or repair position after each rotation. This layout not only improves work efficiency but also makes the entire repair process smoother and more controllable. In actual operation, the operator can flexibly select the detection or repair tool according to the specific condition of the support roller, and can quickly switch tools through a simple rotation operation, greatly shortening non-productive time.

[0036] Of course, in other possible embodiments, the number and layout of the mounting plates 22 can be flexibly adjusted according to actual needs. For example, when it is necessary to add inspection items or repair functions, the number of mounting plates 22 can be increased accordingly, and the required inspection components or repair tools can be configured on the newly added mounting plates 22. At the same time, the layout of the mounting plates 22 can also be adjusted according to the optimization of the workflow to further improve the efficiency and accuracy of the repair operation.

[0037] Secondly, this application also provides a repair device, including an online repair auxiliary bracket as described in any of the above embodiments, and further including repair tools, such as a grinding tool 7 and a turning tool 8, installed on its repair installation station. The grinding tool 7 and the turning tool 8 are respectively installed on the mounting plate 22 of the repair installation station, and the two can be flexibly replaced according to actual repair needs. The grinding tool 7 is mainly used for rough grinding and fine grinding of the support roller surface to remove the wear layer, corrosion layer or uneven area of ​​the surface, and restore the geometric shape and dimensional accuracy of the support roller. The turning tool 8 is suitable for cutting the support roller surface, and by precisely controlling the cutting depth and feed rate, high-precision repair of the support roller surface can be achieved.

[0038] To better understand this utility model, the following is combined with... Figures 1 to 7The technical solution of this utility model is described in detail as follows: First, the device is moved to the initial working position by the linear drive structure 6. The rotary drive structure 4 is activated, rotating the vision inspection device 32 to the working position to perform a global scan imaging of the workpiece surface and identify defect areas. Subsequently, the rotation switches to the laser displacement sensor 31 to accurately measure the three-dimensional morphology of the identified defect areas, obtaining quantitative data such as wear depth and range. Based on the detection data, the control system generates a repair path. The rotary drive structure 4 operates again, switching the grinding tool 7 to the working position for grinding or turning the defect area. After processing, intermediate measurements can be performed again at the inspection station to ensure the grinding or turning effect until the required dimensions and surface finish are achieved.

[0039] This utility model, by setting up an installation body 1, a rotating installation mechanism 2, and a detection structure 3, utilizes a rotatable installation mechanism and a circumferentially arranged multi-station design to integrate detection and repair functions into the same device. It enables rapid and accurate switching between detection and repair tools on the same reference platform, which not only avoids the reference error and time consumption caused by multiple disassembly and assembly and separate positioning in traditional methods, but also significantly improves repair accuracy and work efficiency. Furthermore, it ensures repair quality and reduces rework through real-time detection and feedback before and after repair.
