Description

Technical Field

[0001] This application relates to the field of tire testing equipment technology, and in particular to an explosion-proof device for a tire machine tool durability testing machine. Background Technology

[0002] Tire performance and durability testing machines are used to detect abnormal deformations of tires during operation, such as local bulges, thereby identifying weak points in the tire and enabling performance enhancement of the corresponding parts of the tire.

[0003] Currently, tire machine tool performance durability testing machines in related technologies typically use metal wires surrounding the tire. The tire deformation is detected by observing the contact between the deformed tire and the metal wires.

[0004] However, the detection method of tire contact with metal wire has low sensitivity and is prone to situations where tire deformation is not detected in time, and the tire has already run to the point of bursting. This makes it impossible to reliably detect the tire and identify the weak point, and it also affects the safety of the test. At the same time, the metal wire in contact with the running tire has poor durability, which is not conducive to maintaining good detection reliability.

[0005] The aforementioned technologies have drawbacks, such as poor reliability in tire testing and a high risk of tire blowout. Utility Model Content

[0006] To address the issues of poor reliability and susceptibility to tire explosion during testing, this application provides an explosion-proof device for a tire machine tool durability testing machine.

[0007] The explosion-proof device for the tire machine tool durability testing machine provided in this application adopts the following technical solution:

[0008] An explosion-proof device for a tire machine tool durability testing machine includes: a support mechanism comprising a support frame and a support shaft, the support shaft being rotatably connected to the support frame and used to connect a tire; a drive mechanism disposed on a first side of the support shaft and used to drive the tire to rotate; a detection mechanism comprising a detection bracket, a first detection component, and a second detection component, both disposed on the detection bracket and on a second side of the support shaft, the first detection component facing the tire tread and spaced apart from the tire, the first detection component being used to detect the tire's shape to identify local bulges, the second detection component being spaced apart from the tire and used to measure the tire's temperature; and a controller electrically connected to both the first and second detection components.

[0009] By adopting the above technical solution, the cooperation between the support mechanism and the drive mechanism can stably fix the tire and drive its rotation, thereby simulating the operating state under actual use scenarios. The first detection component in the detection mechanism can accurately identify local protrusions on the tire surface, promptly detecting potential tire blowout risks without contacting the tire, and reducing the possibility of tire blowouts caused by contact with the tire; the second detection component can measure the tire temperature, further enabling early warning of tire blowouts, so as to detect weak points while the tire maintains its intact shape. The connection between the controller and the detection components enables centralized processing and analysis of detection data, improving detection efficiency and accuracy. By setting the interval between the detection mechanism and the tire, the durability of the device is improved, and by reducing the risk of tire blowouts, the safety and reliability of tire machine tool durability testing are enhanced.

[0010] Optionally, the detection mechanism includes a third detection component disposed above the tire, the third detection component being used to detect the tire odor, and the third detection component being electrically connected to the controller.

[0011] By adopting the above technical solution, it is possible to detect tire odor and transmit the detection results to the controller for analysis and processing. This allows for timely detection of potential tire blowout risks during durability testing based on tire odor conditions, thereby improving the safety and reliability of the test.

[0012] Optionally, the detection mechanism includes a moving component, and the third detection component is disposed on the moving component, the moving component driving the third detection component to move horizontally above the tire.

[0013] By adopting the above technical solution, the moving component can drive the third detection component to move horizontally above the tire, thereby achieving accurate tire odor detection. At the same time, the moving component expands the detection range of the third detection component, avoiding the detection blind spot problem caused by the fixed detection position. Furthermore, the moving component can drive the third detection component to move away from the tire, thereby reducing the impact of the third detection component on tire installation and removal, as well as the impact of tire blowout on the third detection component.

[0014] Optionally, it may also include an alarm mechanism electrically connected to the controller.

[0015] By adopting the above technical solution, when an abnormal situation occurs during tire durability testing, the controller can determine whether to trigger an alarm based on data obtained by the testing agency. Once the condition is met, the alarm mechanism will promptly issue an alert, reminding operators to take measures, effectively improving the safety of the testing process and avoiding potential tire blowout risks that could damage equipment and personnel.

[0016] Optionally, the first detection component includes a first detection element and a first adjustment element, wherein the fixed end of the first adjustment element is connected to the detection bracket, and the first detection element is connected to the telescopic end of the first adjustment element.

[0017] By adopting the above technical solution, the first adjusting member in the first detection assembly can adjust the position of the first detection member, thereby ensuring that the first detection member can accurately face the tire tread for detection. This adjustable design improves the flexibility and accuracy of the detection, making the identification of tire shape and local bulges more reliable.

[0018] Optionally, the first detection component is a 3D laser scanner.

[0019] By adopting the above technical solution, the first inspection component uses a 3D laser scanner, which can accurately acquire the 3D shape information of the tire surface. Combined with the fixing and rotation of the tire by the support and drive mechanisms, the 3D laser scanner can scan the tire tread from all directions, accurately detect the tire shape and identify protruding parts, thereby improving the accuracy and reliability of the inspection.

[0020] Optionally, the second detection component includes a second detection element and a second adjustment element, with the fixed end of the second adjustment element connected to the detection bracket and the second detection element connected to the telescopic end of the second adjustment element.

[0021] By adopting the above technical solution, the second detection element is connected to the detection bracket through the second adjustment element, which enables the position adjustment of the second detection element, thereby improving the accuracy and adaptability of temperature measurement.

[0022] Optionally, the second detection element is a temperature measuring gun, and the temperature measuring gun is provided with at least one.

[0023] By adopting the above technical solution, tire temperature can be accurately measured. The temperature gun configuration makes temperature detection more efficient and accurate, and the configuration of multiple temperature guns can be flexibly adjusted to increase the number of detection points according to actual needs, thereby improving detection coverage and data reliability.

[0024] Optionally, the third detection component includes a third detection element and a third adjustment element, wherein the fixed end of the third adjustment element is connected to the detection bracket, and the third detection element is connected to the rotating end of the third adjustment element.

[0025] By adopting the above technical solution, precise adjustment of tire odor detection is achieved. By connecting the third detection element to the rotating end of the third adjustment element, the detection angle and direction of the third detection element can be flexibly adjusted to ensure full coverage of the tire odor detection area; the fixed end of the third adjustment element is connected to the detection bracket, providing a stable support structure and ensuring the reliability and accuracy of the third detection element during the detection process.

[0026] Optionally, the third detection device is an electronic nose.

[0027] By employing the above technical solution, the electronic nose can accurately detect the odor generated by the tire during durability testing. Combined with the rotation function of the third adjustment component, it enables comprehensive monitoring of odors from different locations on the tire. This detection method helps to promptly identify any abnormal chemical reactions or material aging problems that may exist inside the tire, thereby providing more comprehensive data support for assessing the tire's safety and durability.

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

[0029] 1. By inspecting the tire shape through the first detection component, local protrusions on the tire surface can be identified in real time from a distance, effectively improving detection efficiency and accuracy, timely detection of potential risks, and preventing tire blowout accidents;

[0030] 2. The second detection component is used to measure tire temperature. Combined with the controller, it enables real-time monitoring of temperature data, which helps to determine in advance whether the tire is overheating and further improves the safety of the testing process.

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 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.

[0041] 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.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this application discloses an explosion-proof device for a tire machine tool durability testing machine (hereinafter referred to as the "device"). The device includes a support mechanism 1, a drive mechanism 2, a detection mechanism 3, and a controller.

[0043] A detection layer can be provided on the outer surface of the tire 100. The material of the detection layer can be selected as needed, as long as it enables the detection mechanism 3 to reliably detect the shape of the tire 100. The support mechanism 1 includes a support frame 11 and a support shaft 12. The support shaft 12 is rotatably connected to the support frame 11 and is used to support the tire 100. The drive mechanism 2 is located on the first side of the support shaft 12 and is used to drive the tire 100 to rotate. The cooperation between the support mechanism 1 and the drive mechanism 2 can stably fix the tire 100 and drive it to rotate, thereby simulating the operating state under actual use scenarios. The drive mechanism 2 includes a drive motor 21, a drive shaft 22, and a drive wheel 23. The drive motor 21 is mounted on the first side of the support shaft 12. The output end of the drive motor 21 is connected to the drive shaft 22. The drive wheel 23 is connected to the drive shaft 22, so that the drive motor 21 can drive the drive wheel 23 to rotate. The outer peripheral surface of the drive wheel 23 is in contact with the outer peripheral surface of the tire 100, so that the tire 100 can be rotated by the rotational friction of the drive wheel 23, simulating the use state of the tire 100.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the detection mechanism 3 includes a detection bracket 31, a first detection component, and a second detection component. Both the first and second detection components are mounted on the detection bracket 31 and are located on the second side of the support shaft 12. The first detection component is positioned facing the tread of the tire 100 and is spaced apart from the tire 100. The first detection component is used to detect the shape of the tire 100 to identify any local protrusions. The second detection component is also spaced apart from the tire 100 and is used to measure the temperature of the tire 100.

[0045] The first detection component in the detection mechanism 3 can accurately identify localized protrusions on the surface of tire 100, promptly detecting potential blowout risks without contacting tire 100 and reducing the possibility of a blowout due to contact. The second detection component can simultaneously measure the temperature of tire 100, further providing an early warning of tire 100 bursting by measuring the temperature, allowing for the detection of weak points while tire 100 maintains its intact shape. The controller is electrically connected to both the first and second detection components. The connection between the controller and the detection mechanism 3 enables centralized processing and analysis of the detection data, improving detection efficiency and accuracy. The spacing between the detection mechanism 3 and tire 100 enhances the durability of the device, improving the safety and reliability of the tire durability testing machine by reducing the risk of tire 100 blowout.

[0046] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the first detection assembly includes a first detection element 321 and a first adjustment element 322. The fixed end of the first adjustment element 322 is connected to the detection bracket 31, and the first detection element 321 is connected to the telescopic end of the first adjustment element 322, enabling the first detection element 321 to detect the upper end of the tire 100, thereby obtaining images including the tire crown, tire shoulder, and tire sidewall. The first adjustment element 322 in the first detection assembly can adjust the position of the first detection element 321, thereby ensuring that the first detection element 321 can accurately face the tread of the tire 100 for detection, applicable to tires 100 of different specifications. This adjustable design improves the flexibility and accuracy of detection, making the identification of the tire 100's shape and protrusions more reliable.

[0047] Optionally, the first detection element 321 is a three-dimensional laser scanner. The first detection element 321, employing a three-dimensional laser scanner, can accurately acquire three-dimensional shape information of the tire 100 surface. Combined with the fixing and rotation of the tire 100 by the support mechanism 1 and the drive mechanism 2, the three-dimensional laser scanner can scan the tire 100 tread from all directions, accurately detect the tire 100's shape, and identify protruding parts, thereby improving the accuracy and reliability of the detection.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the second detection assembly includes a second detection element 331 and a second adjustment element 332. The fixed end of the second adjustment element 332 is connected to the detection bracket 31, and the second detection element 331 is connected to the telescopic end of the second adjustment element 332. The second detection element 331 is connected to the detection bracket 31 through the second adjustment element 332, which enables the position adjustment of the second detection element 331, thereby improving the accuracy and adaptability of temperature measurement.

[0049] Optionally, the second detection element 331 is a temperature measuring gun, with at least one temperature measuring gun provided to accurately measure the temperature of the tire 100. The use of temperature measuring guns makes temperature detection more efficient and accurate. The configuration of multiple temperature measuring guns can be flexibly adjusted to increase the number of detection points according to actual needs, thereby improving the detection coverage and data reliability. In this embodiment, both the first adjusting element 322 and the second adjusting element 332 can be structures capable of extension and retraction, such as cylinders, hydraulic cylinders, or electric telescopic rods. In other embodiments, the first adjusting element 322 and the second adjusting element 332 can also be swing cylinders or a combination of telescopic cylinders and swing cylinders, depending on the actual situation, as long as the position or attitude of the first detection element 321 and the second detection element 331 can be adjusted.

[0050] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the testing mechanism 3 includes a third testing component. The third testing component is located above the tire 100 and is used to detect the odor of the tire 100. The third testing component is electrically connected to the controller. The third testing component can detect the odor of the tire 100 and transmit the detection results to the controller for analysis and processing. Based on the odor of the tire 100, the potential risk of tire blowout during durability testing can be detected in a timely manner, improving the safety and reliability of the test.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the detection mechanism 3 includes a moving component. A third detection component is disposed on the moving component, and the moving component drives the third detection component to move horizontally above the tire 100. The moving component can drive the third detection component to move horizontally above the tire 100, thereby achieving accurate detection of the tire odor. At the same time, the moving component expands the detection range of the third detection component, avoiding the detection blind spot problem caused by a fixed detection position. Furthermore, the moving component can move the third detection component away from the tire 100, thereby reducing the impact of the third detection component on the installation and removal of the tire 100, as well as the impact of a tire blowout on the third detection component. The moving component may include a moving drive 351, a lead screw 352, and a lead nut 353. The moving drive 351 may be a motor. The output end of the motor is connected to the lead screw 352. The lead screw 352 is rotatably connected to the support mechanism 1. The lead nut 353 is screwed to the lead screw 352 and slides with the support frame 11. It can convert the rotation of the lead screw 352 into the linear movement of the lead screw 352, thereby driving the third detection component to move horizontally. This enables the avoidance of tire blowout when the tire 100 bursts, and improves the service life of the third detection component.

[0052] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the third detection component includes a third detection element 341 and a third adjustment element 342. The fixed end of the third adjustment element 342 is connected to the detection bracket 31, and the third detection element 341 is connected to the rotating end of the third adjustment element 342. By connecting the third detection element 341 to the rotating end of the third adjustment element 342, the detection angle and direction of the third detection element 341 can be flexibly adjusted to ensure full coverage of the odor detection area of ​​the tire 100. The fixed end of the third adjustment element 342 is connected to the detection bracket 31, providing a stable support structure and ensuring the reliability and accuracy of the third detection element 341 during the detection process. Optionally, the third detection element 341 is an electronic nose, which can accurately detect the odor generated by the tire 100 during the durability test. Combined with the rotation function of the third adjustment element 342, it enables comprehensive monitoring of the odor at different locations of the tire 100. This detection method helps to promptly detect any abnormal chemical reactions or material aging problems that may exist inside the tire 100, thereby providing more comprehensive data support for evaluating the safety and durability of the tire 100. The third adjusting element 342 can be a swing cylinder to drive the electronic nose to rotate.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the device also includes an alarm mechanism electrically connected to the controller. When an abnormality occurs in the tire 100 during the durability test, the controller can determine whether to trigger an alarm condition based on the data obtained by the detection mechanism 3. Once the condition is met, the alarm mechanism will promptly issue an alarm to remind the operator to take measures, effectively improving the safety of the test process and avoiding potential tire blowout risks that could damage equipment and personnel. The controller and alarm mechanism can be selected from existing structures according to actual needs, and their principles can be implemented using existing structures. For example, the controller can be a programmable logic controller (PLC); the PLC analyzes the image of the first detection component 321, the temperature of the second detection component 331, and the odor of the third detection component 341. Based on setting the basic shape of the image, the temperature threshold, and the burnt odor of the tire 100 as reference parameters, when the detection results from the detection mechanism 3 are sent to the PLC, the PLC compares them with the reference parameters. If any of the three detection results exceeds the reference parameters, the alarm mechanism will sound an alarm. The alarm mechanism can be selected as needed, such as an audible and visual alarm.

[0054] This device can detect even a slight bulge or protrusion in the tire 100 using the first detection element 321, and trigger an alarm mechanism via the controller, which then automatically shuts down the device. After shutdown, the device can easily identify weak points in the tire 100 at an early stage of bulging while the tire remains intact, facilitating accurate determination of the cause of damage. It is understood that the device also includes necessary structures for connection, support, drive, positioning, limiting, and control functions to ensure its normal operation; the shape, size, material, and quantity of each part of the device can be determined as needed to achieve the corresponding functions.

[0055] The implementation principle of the explosion-proof device for a tire machine tool durability testing machine according to this application embodiment is as follows: The support mechanism 1 and the drive mechanism 2 work together to stably drive the tire 100 to rotate, thereby simulating the operating state under actual use scenarios. The first detection component in the detection mechanism 3 identifies the protrusions on the surface of the tire 100, and promptly detects potential tire blowout risks without contacting the tire 100, reducing the possibility of tire blowout caused by contact with the tire 100. The second detection component measures the temperature of the tire 100, and further realizes the early warning of tire blowout by the temperature of the tire 100, so as to detect weak parts while the tire 100 maintains its intact shape. The third detection component can detect the odor of the tire 100 and transmit the detection results to the controller for analysis and processing, thereby promptly detecting the potential tire blowout risk of the tire 100 during the durability test based on the odor of the tire 100. The connection between the controller and the detection mechanism 3 realizes centralized processing and analysis of detection data, improving detection efficiency and accuracy. By setting the interval between the testing mechanism 3 and the tire 100, the durability of the device is improved, and the safety and reliability of the tire 100 machine tool durability test are enhanced by reducing the risk of tire blowout.

[0056] 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.
