Description

Technical Field

[0001] This application relates to the field of tire inspection equipment technology, and in particular to a device for inspecting the interior and exterior of agricultural and engineering tires. Background Technology

[0002] In the production of different types of tires, such as agricultural tires and engineering tires, tire inspection is a key link to ensure tire quality. In particular, after vulcanization, the inner lining of the tire is inspected to check whether the vulcanization is smooth and whether there are problems such as internal cracks, visible lines in the inner lining, and insufficient rubber bulges. These quality problems directly affect the service life and safety of the tire.

[0003] Currently, the most common method for tire inspection is manual inspection, which requires operators to move the tires to a designated location, such as an inspection platform, to observe them. The tires are then inspected visually or with the help of simple tools to determine their processing quality.

[0004] However, during manual inspection, tires need to be manually moved up and down the inspection platform, which not only consumes a lot of time and energy but also easily leads to operator fatigue. At the same time, due to the weight of the tires, manual operation cannot flexibly adjust the tire position, resulting in a limited observation angle and making it difficult to fully inspect the details of the tire's interior and exterior. The efficiency and accuracy of the inspection need to be improved.

[0005] The aforementioned technologies have the drawback of making tire inspection inconvenient. Utility Model Content

[0006] To address the inconvenience of tire inspection, this application provides a device for inspecting the interior and exterior of agricultural and engineering tires.

[0007] The agricultural and engineering tire lining and appearance inspection device provided in this application adopts the following technical solution:

[0008] An inspection device for the inner lining and appearance of agricultural and engineering tires includes: a lifting mechanism, which includes a lifting bracket and a lifting drive, the fixed end of the lifting drive being connected to the lifting bracket; and an inspection mechanism, which includes a support frame and a mounting assembly, one side of the support frame being connected to the telescopic end of the lifting drive, the other side of the support frame being slidably connected to the lifting bracket, the lifting drive being used to drive the support frame to slide along the lifting bracket, the first end of the mounting assembly being connected to the support frame, and the second end of the mounting assembly being used to mount the tire, so that the mounting height of the tire is adjustable.

[0009] By adopting the above technical solution, the coordination between the lifting mechanism and the inspection mechanism enables adjustable tire mounting height, thus facilitating operators' inspection of the tire's interior and exterior. The lifting drive component moves the support frame along the lifting bracket, thereby adjusting the height of the support frame and changing the height of the mounting components connected to it. This allows for a change in the height of the tire supported by the mounting components, facilitating its lifting to a suitable height for operator observation. Compared to traditional inspection platforms, this device eliminates the need for frequent tire movement, significantly reducing operator workload while improving inspection efficiency and convenience.

[0010] Optionally, the inspection mechanism includes a lighting element located on the side of the lifting bracket near the second end of the mounting assembly.

[0011] By adopting the above technical solution, an illumination element is installed on the side of the lifting bracket near the second end of the mounting assembly, ensuring that light directly illuminates the tire inspection area. This reduces misjudgments caused by insufficient light and simplifies the operation process, eliminating the need for additional handheld lighting tools and reducing the workload of operators. The illumination element effectively improves the lighting conditions of the inspection environment, providing operators with a clearer field of vision when inspecting the tire's interior and exterior, thereby improving the accuracy and efficiency of the inspection.

[0012] Optionally, the lighting element is retractable.

[0013] By adopting the above technical solution, the retractable design of the lighting component allows the lighting range to be flexibly adjusted according to actual inspection needs, avoiding interference from insufficient or excessive light. At the same time, it facilitates changing the position of the light source according to inspection needs, ensuring the comprehensiveness and accuracy of tire interior and exterior inspection.

[0014] Optionally, the mounting assembly includes two mounting groups, each mounting group including a support shaft and a bearing seat. The bearing seat is disposed on the support frame. The first end of the support shaft is rotatably connected to the bearing seat, and the second end of the support shaft is used to mount the tire. The two mounting groups are arranged relatively parallel and spaced apart.

[0015] By adopting the above technical solution, the tire can be stably placed on the support shaft of the mounting component. At the same time, since the first end of the support shaft is rotatably connected to the bearing seat, the tire can rotate freely, which makes it convenient for operators to inspect the inside and outside of the tire from all angles, improving inspection efficiency and convenience.

[0016] Optionally, the surface of the support shaft is rough.

[0017] By adopting the above technical solution, the surface roughness of the support shaft can increase the friction between it and the tire, effectively preventing the tire from slipping or shifting during the installation process. It also facilitates the rotation of the tire by rotating the support shaft, thereby ensuring the stability of the tire and the comprehensiveness of the inspection process.

[0018] Optionally, the lifting mechanism includes a floating joint, which is located at the telescopic end of the lifting drive member and is used to connect the support frame.

[0019] By adopting the above technical solution, the floating joint can effectively compensate for the installation error between the lifting drive component and the support frame, improve the flexibility and stability of the connection, thereby ensuring that the support frame runs smoothly during the lifting process, reducing the vibration or jamming that may be caused by rigid connection, and improving the reliability and service life of the overall device.

[0020] Optionally, the lifting mechanism includes a first slide rail and a first slider. The first slide rail is disposed on one side of the lifting bracket, and the first slider is slidably connected to the first slide rail. The first slider is connected to the support frame, so that the vertical height of the support frame is adjustable.

[0021] By adopting the above technical solution, the coordinated use of the first slide rail and the first slider in the lifting mechanism allows the support frame to slide smoothly along the lifting bracket, thereby adjusting the vertical height of the support frame. This effectively solves the problem of inconvenient operation of the original inspection platform, significantly improves the convenience and accuracy of tire mounting height adjustment, reduces the labor intensity of operators, and improves inspection efficiency.

[0022] Optionally, it further includes a moving mechanism, which includes a base, a second slide rail, a second slider, and a driving component. The second slide rail is disposed on the base, the second slider is slidably connected to the second slide rail, the lifting bracket is connected to the second slider, the driving component is disposed on the base, the output end of the driving component is connected to the lifting bracket, and the driving component is used to drive the lifting bracket to move horizontally.

[0023] By adopting the above technical solution, the moving mechanism enables the lifting bracket to move horizontally as a whole, thereby facilitating tire position adjustment and improving inspection efficiency and convenience. The base provides a stable support foundation for the entire moving mechanism, ensuring the device remains stable during movement; the cooperation between the second slide rail and the second slider enables smooth horizontal movement of the lifting bracket, reducing resistance and vibration during movement; the introduction of the drive component automates the horizontal movement of the lifting bracket, reducing the intensity of manual operation and improving the accuracy and convenience of operation.

[0024] Optionally, the drive assembly includes a movable drive component, a lead screw, and a lead screw nut. The two ends of the lead screw are rotatably connected to the base. The output end of the movable drive component is drively connected to one end of the lead screw. The lead screw nut is screwed onto the lead screw. The lifting bracket is connected to the lead screw nut. The lead screw nut is used to drive the lifting bracket to move horizontally.

[0025] By adopting the above technical solution, the drive assembly enables the lifting bracket to move horizontally, facilitating tire position adjustment to meet different inspection needs. Specifically, the engagement of the lead screw and nut achieves precise horizontal displacement control, improving operational convenience and accuracy; the transmission connection of the moving drive component further ensures the stability and reliability of the movement process, reducing manual intervention and improving work efficiency.

[0026] Optionally, the moving mechanism includes a coupling for connecting the output end of the moving drive component and the lead screw.

[0027] By adopting the above technical solution, the coupling effectively connects the output end of the moving drive component and the lead screw, ensuring stable and reliable transmission between them. This design avoids reduced transmission efficiency or equipment failure caused by unstable connection, compensates for relative misalignment during assembly, and thus improves the smoothness and accuracy of the entire inspection device during horizontal movement. At the same time, the use of the coupling facilitates assembly and maintenance, further enhancing the practicality and economy of the device.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By coordinating the lifting and inspection mechanisms, the tire mounting height is adjustable, eliminating the need for operators to manually move tires, significantly reducing labor intensity and improving inspection efficiency;

[0030] 2. The sliding connection design between the support frame and the lifting bracket, combined with the movement of the lifting drive component, allows for flexible adjustment of the tire position, optimizes the observation angle, and facilitates a comprehensive inspection of the tire's internal details;

[0031] 3. The lighting further enhances the convenience of inspection, especially in low-light conditions, clearly displaying the condition of the inner surface of the tire and ensuring the accuracy and reliability of the inspection. Attached Figure Description

[0041] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0043] like Figure 1 and Figure 2As shown in the embodiment of this application, an inspection device (hereinafter referred to as "the device") for the interior and exterior of agricultural and engineering tires is disclosed. The device includes a lifting mechanism 1 and an inspection mechanism 2. The cooperation between the lifting mechanism 1 and the inspection mechanism 2 enables the adjustability of the tire 100 mounting height, thereby facilitating the operator to inspect the interior and exterior of the tire 100.

[0044] The lifting mechanism 1 includes a lifting bracket 11 and a lifting drive component 12, while the inspection mechanism 2 includes a support frame 21 and a mounting assembly 22. The lifting bracket 11 provides support for the lifting drive component 12 and the inspection mechanism 2. The fixed end of the lifting drive component 12 is connected to the lifting bracket 11. One side of the support frame 21 is connected to the telescopic end of the lifting drive component 12, and the other side of the support frame 21 is slidably connected to the lifting bracket 11. The first end of the mounting assembly 22 is connected to the support frame 21, and the second end of the mounting assembly 22 is used to mount the tire 100. The lifting drive component 12 drives the support frame 21 to slide along the lifting bracket 11, thereby adjusting the height of the support frame 21. The support frame 21 drives the mounting assembly 22 to move, thus making the mounting height of the tire 100 supported by the mounting assembly 22 adjustable, allowing the tire 100 to be lifted to a suitable height for easy observation by the operator. Compared to traditional inspection platforms, this device eliminates the need for frequent manual handling of the tire 100, significantly reducing the labor intensity of the operator while improving inspection efficiency and convenience.

[0045] like Figure 1 and Figure 2 As shown, optionally, the mounting assembly 22 includes two mounting groups, each including a support shaft 221 and a bearing seat 222. The bearing seat 222 is mounted on the support frame 21. The first end of the support shaft 221 is rotatably connected to the bearing seat 222, and the second end of the support shaft 221 is used to mount the tire 100, allowing the tire 100 to be placed vertically. The two mounting groups are arranged relatively parallel and horizontally spaced. In this embodiment, the support shaft 221 is used to receive the processed and flipped tire 100 conveyed by the previous process conveying production line. The support shaft 221 extends horizontally, allowing the tire 100 to be stably placed on the support shaft 221 of the mounting assembly 22. At the same time, since the first end of the support shaft 221 is rotatably connected to the bearing seat 222, the tire 100 can rotate freely, facilitating operators to inspect the inside and outside of the tire 100 from all angles, improving inspection efficiency and convenience.

[0046] The lifting drive component 12 drives the support frame 21 to move, thereby changing the height of the support shaft 221 and thus adjusting the height of the tire 100. The lifting drive component 12 can be a cylinder, a hydraulic cylinder, or an electric telescopic rod, or any structure capable of extension and retraction. Two bearing seats 222 can be installed in the same support assembly, respectively positioned on opposite sides of the support frame 21. The support shaft 221 passes through both bearing seats 222, spaced apart to improve the reliability of the support for the support shaft 221. The rotation of the support shaft 221 can be achieved manually or by using a drive structure, such as a motor, whose output is connected to the first end of the support shaft 221, causing the support shaft 221 to rotate, thereby rotating the tire 100 for comprehensive inspection. It is understood that the rotation of the support shaft 221 also reduces rotational resistance when the tire 100 rotates, allowing for convenient manual rotation of the tire 100 for 360° inspection. The cooperation between the support shaft 221 and the bearing seat 222 enables the stable installation of the tire 100. The two sets of installation groups are relatively parallel and spaced apart, which can ensure that the tire 100 is subjected to uniform force during the installation process and avoid tilting or slipping.

[0047] like Figure 1 and Figure 2 As shown, optionally, the surface of the support shaft 221 is rough. In this embodiment, the roughness of the support shaft 221 can be improved by surface knurling. The roughness of the support shaft 221 can increase the friction between it and the tire 100, effectively preventing the tire 100 from slipping or shifting during installation, and facilitating the rotation of the tire 100 by rotating the support shaft 221, thereby ensuring the stability of the tire 100 and the comprehensiveness of the inspection process.

[0048] like Figure 1 and Figure 2 As shown, optionally, the lifting mechanism 1 includes a first slide rail 14 and a first slider 15. The first slide rail 14 is located on one side of the lifting bracket 11, and the first slider 15 is slidably connected to the first slide rail 14. The first slider 15 is connected to the support frame 21, making the vertical height of the support frame 21 adjustable. The cooperative use of the first slide rail 14 and the first slider 15 allows the support frame 21 to slide smoothly along the lifting bracket 11, thereby adjusting the vertical height of the support frame 21. This effectively solves the problem of inconvenient operation of the original inspection platform, significantly improves the convenience and accuracy of tire 100 mounting height adjustment, reduces the labor intensity of operators, and improves inspection efficiency.

[0049] like Figure 1 and Figure 2As shown, optionally, the lifting mechanism 1 includes a floating joint 13, which is located at the telescopic end of the lifting drive component 12 and is used to connect the support frame 21. The floating joint 13 can effectively compensate for the installation error between the lifting drive component 12 and the support frame 21, improve the flexibility and stability of the connection, thereby ensuring that the support frame 21 runs smoothly during lifting, reducing vibration or jamming that may occur due to rigid connection, and improving the reliability and service life of the overall device. The floating joint 13 can better solve the problem of relative eccentricity between the lifting drive component 12 and the support frame 21, reduce the installation difficulty of the lifting drive component 12 and the support frame 21, and achieve effective pushing even when the coaxiality between the lifting drive component 12 and the support frame 21 is low, thus slowing down the damage rate of the sealing ring of the cylinder of the lifting drive component 12 and extending the service life of the cylinder. Specifically, the floating joint 13 can be a floating joint connector.

[0050] like Figure 1 and Figure 2 As shown, optionally, the inspection mechanism 2 includes an illumination element 23, which is located on the side of the lifting bracket 11 near the second end of the mounting assembly 22. This illumination element 23 allows light to directly illuminate the area of ​​the tire 100 to be inspected, reducing misjudgments caused by insufficient light. It also simplifies the operation process, eliminating the need for additional handheld lighting tools and reducing the workload of operators. The illumination element 23 effectively improves the lighting conditions of the inspection environment, providing operators with a clearer field of vision when inspecting the inside and outside of the tire 100, thereby improving the accuracy and efficiency of the inspection.

[0051] like Figure 1 and Figure 2 As shown, optionally, the lighting element 23 is retractable. The lighting fixture may include a lamp body and a telescopic connector, through which the lamp body can be moved. The type of lamp body and the power supply method are not limited. The telescopic connector can be a flexible component or a telescopic structure, selected as needed. The retractable design of the lighting element 23 allows the lighting range to be flexibly adjusted according to actual inspection needs, avoiding interference from insufficient or excessive light. Simultaneously, it facilitates changing the position of the light source as needed, ensuring the comprehensiveness and accuracy of the tire 100's internal and external inspections.

[0052] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the device further includes a moving mechanism 3 for moving the tire 100 from the previous workstation to the observation workstation for observation. The moving mechanism 3 includes a base 31, a second slide rail 32, a second slider 33, and a drive assembly 34. The second slide rail 32 is disposed on the base 31, and the second slider 33 is slidably connected to the second slide rail 32. The lifting bracket 11 is connected to the second slider 33. The drive assembly 34 is disposed on the base 31, and the output end of the drive assembly 34 is connected to the lifting bracket 11. The drive assembly 34 is used to drive the lifting bracket 11 to move horizontally. The shape of the lifting bracket 11 is not limited, as long as it can provide stable support and connection. In this embodiment, the upper end of the lifting bracket 11 extends vertically to provide support for the inspection mechanism 2, and the lower end of the lifting bracket 11 is used to connect to the moving mechanism 3.

[0053] The moving mechanism 3 enables the lifting bracket 11 to move horizontally as a whole, facilitating the adjustment of the tire 100's horizontal position and improving inspection efficiency and convenience. The base 31 provides a stable support foundation for the entire moving mechanism 3, ensuring stability during movement. The cooperation between the second slide rail 32 and the second slider 33 enables smooth horizontal movement of the lifting bracket 11, reducing resistance and vibration during movement. The introduction of the drive assembly 34 automatically controls the horizontal movement of the lifting bracket 11, reducing the intensity of manual operation and improving operational accuracy and convenience. Specifically, the second slider 33 can be bolted to the bottom of the lifting bracket 11.

[0054] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the drive assembly 34 includes a movable drive component 341, a lead screw 342, and a lead nut 343. Both ends of the lead screw 342 are rotatably connected to the base 31. The output end of the movable drive component 341 is drive-connected to one end of the lead screw 342. The lead nut 343 is screwed onto the lead screw 342. The lifting bracket 11 is connected to the lead nut 343, which drives the lifting bracket 11 to move horizontally. The movable drive component 341 can be a motor, and the lead screw 342 can be a ball screw. Since the lifting bracket 11 connected to the lead nut 343 is slidably connected to the base 31, the rotation of the lifting bracket 11 is restricted through the connection between the base 31 and the lifting bracket 11, so that the rotation of the lead screw 342 can be converted into the linear movement of the lead nut 343. In other embodiments, one end of the lead screw 342 can be rotatably connected to the base 31, and the other end can be drive-connected to the movable drive component 341, with the movable drive component 341 fixedly connected to the base 31. Necessary support structures can be provided at the moving drive component 341 to ensure that the moving drive component 341 can be reliably connected to the lead screw 342.

[0055] The drive assembly 34 enables the lifting bracket 11 to move horizontally, facilitating the adjustment of the tire 100 position to meet different inspection needs. Specifically, the cooperation between the lead screw 342 and the nut 343 achieves precise horizontal displacement control, improving the convenience and accuracy of operation; the transmission connection of the moving drive component 341 further ensures the stability and reliability of the movement process, reduces manual intervention, and improves work efficiency.

[0056] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the moving mechanism 3 includes a coupling 344, which connects the output end of the moving drive component 341 and the lead screw 342. The coupling 344 effectively connects the output end of the moving drive component 341 and the lead screw 342, ensuring stable and reliable transmission between them. This design avoids reduced transmission efficiency or equipment failure due to unstable connection, compensates for relative misalignment during assembly, and thus improves the smoothness and accuracy of the entire inspection device during horizontal movement. Simultaneously, the use of the coupling 344 facilitates assembly and maintenance, further enhancing the practicality and economy of the device. The coupling 344 can be a quincunx flexible coupling 344, which can compensate for the relative misalignment between the motor and the lead screw 342, achieving shock absorption and ensuring smooth movement of the lifting bracket 11 driven by the lead screw 342.

[0057] It is understandable that the device also includes necessary structures for connection, support, drive, positioning, limiting and control functions, so that the device can operate normally; the shape, size, material and number of each part of the device can be determined as needed, as long as the corresponding functions can be achieved.

[0058] The implementation principle of the agricultural and engineering tire interior and exterior inspection device according to this application embodiment is as follows: The lifting drive component 12 drives the support frame 21 to move along the lifting bracket 11, thereby adjusting the height of the support frame 21. This changes the height of the mounting component 22 connected to the support frame 21, thus changing the height of the tire 100 supported by the mounting component 22. This allows the tire 100 to be lifted to a suitable height for easy observation by the operator. Compared to traditional inspection platforms, this device eliminates the need for frequent manual handling of the tire 100, significantly reducing the labor intensity of the operator while improving inspection efficiency and convenience.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
