Description

Technical Field

[0001] This application relates to the technical field of plastic running track testing, and in particular to a device for detecting the impact absorption and vertical deformation of plastic running tracks. Background Technology

[0002] Currently, synthetic running tracks, also known as all-weather athletic tracks, are composed of polyurethane prepolymer, mixed polyethers, waste tire rubber, EPDM rubber granules or PU particles, pigments, additives, and fillers. Synthetic running tracks possess characteristics such as good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which are conducive to athletes' speed and technique, effectively improving athletic performance and reducing the rate of falls and injuries. Composed of materials such as polyurethane rubber, synthetic running tracks have a certain degree of elasticity and color, and possess a certain degree of UV resistance and aging resistance, making them internationally recognized as the best all-weather outdoor sports flooring material. After the synthetic running track is completed, comprehensive testing is required, with testing of its impact absorption performance and vertical deformation performance being particularly important. Related technologies typically use a heavy hammer to impact the ground, and sensors record the magnitude of track deformation to test the impact absorption performance and vertical deformation performance of the synthetic running track.

[0003] Regarding the aforementioned technologies: when testing plastic running tracks, the height of the weights is often not precisely adjustable according to actual needs, which can easily lead to a decrease in the accuracy of the test results. Utility Model Content

[0004] To improve the accuracy of test results, this application provides a device for testing the impact absorption and vertical deformation of plastic running tracks.

[0005] This application provides a device for detecting the impact absorption and vertical deformation of a plastic running track, which adopts the following technical solution:

[0006] A device for detecting impact absorption and vertical deformation of a plastic running track, comprising:

[0007] Supporting institutions;

[0008] A gravity mechanism includes a drive component, a movable component, and a counterweight. The drive component is mounted on the support mechanism. The movable component and the counterweight are slidably mounted on the support mechanism. The counterweight is located below the movable component. The movable component can attract the counterweight. The movable component is connected to the drive component. The drive component can drive the counterweight to move through the movable component.

[0009] A positioning mechanism includes an adjusting member and several positioning members, wherein the several positioning members are distributed sequentially along the height direction of the support mechanism, and the adjusting member is disposed on the support mechanism. The adjusting member is used to adjust the position of the several positioning members so that the positioning members position the movable component.

[0010] The detection mechanism is mounted on the support mechanism and located below the weight.

[0011] By adopting the above technical solutions, the support mechanism provides a stable foundation, ensuring the stability and reliability of the entire testing device. The drive component can precisely control the movement of the movable component, which in turn moves the weight. Furthermore, the adjusting component, through the positioning component, can precisely position the movable component, thereby achieving precise adjustment of the weight's height. This avoids testing errors caused by inaccurate height adjustment to a certain extent, thus improving the accuracy of the test results. In addition, the testing mechanism can monitor the impact absorption and vertical deformation of the weight on the plastic track in real time, ensuring the accuracy and reliability of the test data.

[0012] Optionally, the support mechanism includes a first support plate and a second support plate, the first support plate and the second support plate are disposed opposite to each other, a plurality of support rods are disposed between the first support plate and the second support plate, the drive component is disposed on the first support plate, the detection mechanism is movably disposed on the second support plate, the movable component and the counterweight are respectively slidably disposed on the support rods, the counterweight is disposed close to the second support plate, and the adjusting component and the positioning component are respectively disposed on the support rods.

[0013] By adopting the above technical solution, the multiple support rods between the first support plate and the second support plate not only ensure the stability and structural strength of the entire device, but also provide a reliable sliding track for the moving components and the counterweight, enabling the counterweight to move smoothly in the vertical direction.

[0014] Optionally, the support rod is provided with positioning grooves, the number of positioning grooves being equal to the number of positioning components, and a plurality of positioning grooves being distributed sequentially along the length direction of the support rod. The support rod is provided with a sliding groove along its own length direction, the sliding groove communicating with the plurality of positioning grooves. One positioning component is slidably inserted into one positioning groove, and one end of the adjusting component is slidably inserted into the sliding groove. The adjusting component is used to push the positioning component out of the positioning groove.

[0015] By adopting the above technical solution, when the adjusting component moves along the slide groove, it can push the positioning component to extend from the positioning groove, thereby facilitating the positioning of the moving component and achieving precise positioning of the hammer height. This structure not only improves the controllability of the hammer's falling position during the testing process but also ensures the consistency of testing conditions for each test, thus improving the accuracy and reliability of the test results. Furthermore, the multi-stage positioning grooves allow for flexible selection of the appropriate hammer falling height according to different testing needs, further enhancing the applicability and flexibility of the device.

[0016] Optionally, a pressure sensor is provided on the positioning member, and the pressure sensor detects the moving component when the moving component abuts against the positioning member.

[0017] By adopting the above technical solution, when the moving component comes into contact with the positioning component, the pressure sensor can accurately detect the position of the moving component, ensuring that the weight is released at the predetermined height, thereby achieving accurate measurement of the impact absorption performance and vertical deformation performance of the plastic track, and improving the reliability and accuracy of the test results.

[0018] Optionally, one end of the positioning member extends into the groove and is provided with a first inclined surface, the first inclined surface being inclined toward the first support plate, and one end of the adjusting member is provided with a second inclined surface, the second inclined surface being parallel to the first inclined surface.

[0019] By adopting the above technical solution, the first inclined surface at one end of the positioning component and the second inclined surface at one end of the adjusting component cooperate with each other. When the adjusting component moves along the slide groove, the interaction force between the two parallel inclined surfaces converts the vertical movement of the adjusting component into the horizontal movement of the positioning component. This design allows the adjusting component to more precisely control the extension position of the positioning component, thereby achieving precise positioning of the moving component, ensuring accurate adjustment of the weight height, and ultimately improving the accuracy of the test results.

[0020] Optionally, a receiving groove is formed on the inner wall of the positioning groove, an elastic element is provided in the receiving groove, a protrusion is provided on the positioning element, the protrusion is slidably inserted into the receiving groove, the elastic element is disposed between the protrusion and the inner wall of the receiving groove, and the elastic element is used to push the protrusion to move closer to the sliding groove.

[0021] By adopting the above technical solution, when the adjusting member pushes the positioning member out of the positioning groove, the elastic member can push the positioning member to move closer to the slide groove through the protrusion, so that the positioning member applies a force to the adjusting member to clamp the adjusting member in the slide groove, thereby reducing the possibility of the adjusting member's position shifting. When the adjusting member and the positioning member are separated, the elastic member can push the positioning member back into the positioning groove through the protrusion to avoid the positioning member interfering with the moving component.

[0022] Optionally, the slide groove has a T-shaped cross-section, with the smaller end of the slide groove penetrating the surface of the support rod, and the shape of the end of the adjusting member inserted into the slide groove is adapted to the shape design of the slide groove.

[0023] By adopting the above technical solution, the cross-section of the slide is designed in a T-shape, which allows the adjusting component to slide stably within the slide without disengaging, while ensuring smooth movement of the adjusting component. This structural design not only improves the stability of the adjusting component but also enhances the reliability of the overall device.

[0024] Optionally, the movable component includes a movable plate and an electromagnet. The movable plate is slidably mounted on the support rod, and the electromagnet is mounted on the movable plate and close to the counterweight. When the positioning member positions the movable plate, the electromagnet is de-energized.

[0025] By adopting the above technical solution, the electromagnet can attract the weight, so that the movable plate can move the weight to a specified height by the electromagnet. When the positioning component positions the movable plate, the electromagnet is de-energized, so that the electromagnet no longer attracts the weight. This helps to ensure that the weight is released at a specific position and avoids inaccurate weight position caused by continuous operation of the electromagnet, thereby improving the accuracy and reliability of the detection results.

[0026] Optionally, one end of the adjusting member extends out of the groove, and the movable plate has a relief groove adapted to the adjusting member, through which the adjusting member can pass.

[0027] By adopting the above technical solution, a groove extends from one end of the adjusting component, allowing operators to easily push the adjusting component and adjust the position of the positioning component. Simultaneously, a clearance groove is provided on the movable plate to accommodate the adjusting component, ensuring that the adjusting component and the movable plate do not easily interfere. This not only improves the ease of operation of the adjusting component but also ensures that the movable plate can slide smoothly on the support rod, thereby achieving precise control of the weight height and further improving the accuracy of the test results.

[0028] Optionally, a through slot is provided on the second support plate. The detection mechanism includes a detector, a buffer, an impact pin, and a detection platform. The detector is disposed on the second support plate, the buffer is disposed in the through slot, the impact pin is disposed at the end of the buffer near the weight, and the detection platform is disposed at the end of the buffer away from the weight. The detection platform is connected to the detector and can extend through the through slot.

[0029] By adopting the above technical solution, when the plastic running track needs to be tested, a weight is dropped from a designated height to apply force to the impact pin. The impact pin then applies force to the testing platform through a buffer, causing the testing platform to impact the plastic running track. At this time, the detector can monitor the movement status and impact force of the testing platform in real time, thus facilitating the testing of the plastic running track and ensuring the accuracy and reliability of the test data.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Through the cooperation of the moving components, adjusting parts and positioning parts, the height of the counterweight can be precisely adjusted, which helps to reduce the detection error caused by inaccurate height adjustment, and thus helps to improve the accuracy of the detection results;

[0032] 2. Through the cooperation of the positioning element, the protrusion and the elastic element, the elastic element can apply force to the adjusting element through the protrusion and the positioning element in sequence to clamp the adjusting element in the slide groove, thereby reducing the possibility of the adjusting element's position shifting. When the adjusting element is separated from the positioning element, the elastic element can push the positioning element back into the positioning groove through the protrusion to avoid the positioning element interfering with the moving component.

[0033] 3. The setting of the first and second inclined surfaces allows the vertical movement of the adjusting component to be converted into the horizontal movement of the positioning component through the interaction force between the two parallel inclined surfaces when the adjusting component moves in the slide groove. This enables precise control of the extension position of the positioning component, thereby achieving accurate positioning of the moving component. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model.

[0044] Reference Figure 1 A device for detecting impact absorption and vertical deformation of a plastic running track includes a support mechanism 1, a gravity mechanism 2, a positioning mechanism 3, and a detection mechanism 4. The gravity mechanism 2, positioning mechanism 3, and detection mechanism 4 are respectively mounted on the support mechanism 1. The gravity mechanism 2 applies force to the detection mechanism 4 to facilitate the detection of deformation data of the plastic running track. The positioning mechanism 3 precisely adjusts the height of the gravity mechanism 2, thereby improving the accuracy and reliability of the detection results.

[0045] The support mechanism 1 includes a first support plate 11 and a second support plate 12. The first support plate 11 and the second support plate 12 are arranged opposite to each other, and multiple support rods 13 are arranged between them. These support rods 13 can be made of stainless steel to ensure sufficient rigidity and stability. In this embodiment, two support rods 13 are provided, and the two support rods 13 are arranged opposite to each other.

[0046] The second support plate 12 is provided with a support leg 14, which is used to contact the ground to support the entire device, thereby preventing the device from shifting or shaking during the detection process and ensuring the stability of the device.

[0047] Reference Figure 2 and Figure 3 The support rod 13 has several positioning grooves 131, which are distributed sequentially along the length of the support rod 13. Each positioning groove 131 has a receiving groove 132 on its inner wall (see reference). Figure 4 Furthermore, the support rod 13 is provided with a sliding groove 133 along its own length direction, and the sliding groove 133 is connected to a number of positioning grooves 131. In this embodiment, the cross-section of the sliding groove 133 is T-shaped, and the smaller end of the sliding groove 133 penetrates through the surface of the support rod 13.

[0048] Reference Figure 1 and Figure 3 The positioning mechanism 3 includes an adjusting member 31 and several positioning members 32. The number of positioning members 32 is equal to the number of positioning slots 131. One positioning member 32 is slidably inserted into a positioning slot 131, and one end of the positioning member 32 extends into a sliding groove 133 and is provided with a first inclined surface 321, which is inclined towards the first support plate 11. A pressure sensor 322 is provided at the end of the positioning member 32 away from the sliding groove 133.

[0049] Reference Figure 3 The positioning member 32 has an integrally formed protrusion 323, which is slidably inserted into the receiving groove 132, and an elastic member 134 is provided between the protrusion 323 and the inner wall of the receiving groove 132. In this embodiment, the elastic member 134 is a spring, so that the elastic member 134 can be used to push the protrusion 323 to move closer to the slide groove 133.

[0050] Reference Figure 2 and Figure 3 One end of the adjusting member 31 is slidably inserted into the slide groove 133 and adapted to the shape design of the slide groove 133, so that the adjusting member 31 is not easy to disengage from the slide groove 133, and the other end of the adjusting member 31 extends out of the slide groove 133, so that the operator can easily push the adjusting member 31.

[0051] Reference Figure 3The adjusting member 31 has a second inclined surface 311 at one end extending into the slide groove 133, which is parallel to the first inclined surface 321. When it is necessary to extend the designated positioning member 32 out of the positioning groove 131, the adjusting member 31 is moved. The adjusting member 31 applies a force to the first inclined surface 321 through the second inclined surface 311 to drive the positioning member 32 out of the positioning groove 131. At this time, the elastic member 134 is compressed, and the elastic member 134 applies a force to the adjusting member 31 through the protrusion 323 and the positioning member 32 to clamp the adjusting member 31 in the slide groove 133, thereby reducing the possibility of the adjusting member 31 shifting position.

[0052] Reference Figure 1 and Figure 3 When the adjusting member 31 separates from the positioning member 32, the elastic member 134 can push the positioning member 32 back into the positioning groove 131 through the protrusion 323, so as to avoid the positioning member 32 interfering with the movable component 22, ensuring the smooth movement of the movable component 22, and positioning when it extends.

[0053] Reference Figure 1 The gravity mechanism 2 includes a drive assembly 21, a movable assembly 22, and a counterweight 23. The drive assembly 21 is mounted on the first support plate 11, and the movable assembly 22 is slidably mounted on the support rod 13 and connected to the drive assembly 21. The drive assembly 21 is used to drive the movable assembly 22 to rise and fall.

[0054] The drive assembly 21 includes a lifting motor 211 and a transmission rod 212. The lifting motor 211 is mounted on the first support plate 11, and the transmission rod 212 is slidably connected to the first support plate 11 and arranged parallel to the support rod 13. One end of the transmission rod 212 is connected to the lifting motor 211, and the other end is connected to the movable assembly 22, thereby enabling the lifting motor 211 to drive the movable assembly 22 to rise and fall via the transmission rod 212. In other embodiments, the drive assembly 21 may also be a pneumatic cylinder or a hydraulic cylinder.

[0055] The movable component 22 includes a movable plate 221 and an electromagnet 222. The movable plate 221 is slidably mounted on the support rod 13, and the electromagnet 222 is mounted on the movable plate 221 and positioned close to the counterweight 23.

[0056] Reference Figure 1 and Figure 4 The movable plate 221 is provided with a relief groove 2211 adapted to the adjustment member 31. When the movable plate 221 passes the adjustment member 31, the adjustment member 31 can pass through the relief groove 2211, so that the movable plate 221 is less likely to interfere with the adjustment member 31.

[0057] When the weight 23 needs to be moved to a designated height, the positioning component 32 at the designated position first extends out of the positioning slot 131. Then, the electromagnet 222 is energized, causing it to attract the weight 23. Next, the lifting motor 211 is started. The lifting motor 211 drives the weight 23 upward through the transmission rod 212, the movable plate 221, and the electromagnet 222. When the movable plate 221 rises to contact the positioning component 32, the weight 23 reaches the designated height. At this time, the pressure sensor 322 detects the movable plate 221, and the electromagnet 222 is de-energized, allowing the weight 23 to fall.

[0058] It should be noted that, in this embodiment, how to make the pressure sensor 322 and the electromagnet 222 work together is a conventional technical means for those skilled in the art, and therefore will not be described in detail in this embodiment.

[0059] Reference Figure 5 A vertical through-slot 121 is formed on the second support plate 12, penetrating both the upper and lower surfaces of the second support plate 12 to form a channel for the vertical movement of the detection platform 44. The detection mechanism 4 includes a detector 41, a buffer 42, an impact pin 43, and a detection platform 44. The detector 41 is mounted on the second support plate 12, the buffer 42 is disposed within the through-slot 121, the impact pin 43 is connected to the end of the buffer 42 near the counterweight 23, and the detection platform 44 is connected to the end of the buffer 42 away from the counterweight 23. In this embodiment, the buffer 42 is a spring, which can reduce the impact on the detection mechanism 4. In other embodiments, the buffer 42 can also be made of other elastic materials.

[0060] The testing platform 44 extends through the through slot 121 and is fixedly connected to the detector 41. In this embodiment, the detector 41 is a displacement sensor, which enables the detector 41 to monitor the movement state of the testing platform 44 in real time, so as to complete the testing of the plastic running track.

[0061] The implementation principle of the impact absorption and vertical deformation detection device for plastic running tracks in this embodiment is as follows: When it is necessary to detect the plastic running track, the detection device is first placed in a designated position, and according to the detection requirements, the positioning member 32 at the designated position is pushed out of the positioning groove 131 by the adjusting member 31. Then, the lifting motor 211 is started and the electromagnet 222 is energized, so that the lifting motor 211 drives the electromagnet 222 to contact the weight 23 through the transmission rod 212 and the movable plate 221, so that the electromagnet 222 attracts the weight 23.

[0062] Next, the lifting motor 211 reverses its operation to raise the weight 23. When the movable plate 221 contacts the positioning element 32, the lifting motor 211 stops. At this point, the weight 23 reaches the designated height, the pressure sensor 322 detects the movable plate 221, and the electromagnet 222 is de-energized, causing the weight 23 to fall and impact the impact pin 43. The impact pin 43 applies force to the detection platform 44 through the buffer element 42. The detection platform 44, impacted, penetrates the through groove 121 and applies the impact force to the surface of the plastic track, causing the detection platform 44 to impact the plastic track. At this time, the detector 41 records the deformation of the plastic track caused by the impact, thereby achieving accurate detection of the impact absorption performance and vertical deformation performance of the plastic track.

[0063] 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.
