Description

Technical Field

[0001] The utility model relates to the field of plastic runway detection equipment, in particular to a movable abrasion resistance detection device for plastic runways. Background Art

[0002] In order to improve the anti-slip effect of plastic runways, an anti-slip particle layer is usually scattered on the top surface of the plastic runway, and the anti-slip particles are used to increase the friction with the soles of athletes' shoes, thereby reducing the slipping problem.

[0003] Due to production process or binder quality problems, the anti-slip particles will separate from the elastic layer of the plastic runway under the action of friction and cause shedding problems, that is, they are not wear-resistant. Therefore, abrasion resistance detection is required after construction. In the prior art, the invention patent with the application number 2023113018303 discloses an abrasion resistance detection device for a plastic runway in a stadium. The abrasion resistance of the plastic runway is detected by simulating the foot movements of athletes with a grinding wheel in frictional contact with the sample. However, the structure is complex, the cost is high, and only sample detection can be carried out, and the plastic runway at the construction site cannot be detected, so improvements are needed.

Description of the Drawings

[0015] Figure 1 is a structural schematic diagram of the present utility model. Detailed Embodiment

[0016] The following combines Figure 1 and further illustrates the technical solution of the present utility model through specific embodiments.

[0017] Such as Figure 1 The mobile wear resistance detection device for a plastic runway shown includes: a trolley 1, a gantry 8, a sliding seat 12, a cam 9 and a motor 10. The trolley 1 is movably arranged on the plastic runway 14. In this embodiment, the bottom of the trolley 1 is provided with casters 15 with self-brakes, which can move flexibly and can change positions at the construction site to detect the wear resistance of multiple positions on the plastic runway.

[0018] The gantry 8 is arranged in the trolley 1 in a liftable manner. In this embodiment, a second screw rod 4 penetrating the trolley 1 upward is arranged on the gantry 8, and second nuts 5 are arranged on the second screw rod 4 above and below the trolley 1, which is convenient for height adjustment and fixation of the gantry 8.

[0019] Vertically extending guide rails 13 are symmetrically arranged on both sides inside the gantry 8, and the sliding seat 12 is arranged on the guide rails 13 in a liftable manner. In this embodiment, a slider 17 located on the guide rail 13 is arranged on the back of the sliding seat 12, which improves the lifting stability of the sliding seat 12.

[0020] The motor 10 is horizontally arranged at the lower part of the sliding seat 12 respectively. In this embodiment, the cam 9 is arranged on the rotating shaft of the motor 10, and the cam 9 is driven to rotate by the motor 10. Sandpaper is arranged on the outer circle of the cam 9, and during the rotation of the cam 9, friction is carried out with the surface of the plastic runway through the sandpaper to realize wear resistance detection. The sandpaper can be fixed on the outer circle of the cam 9 through glue, with stable structure, convenient replacement and low cost.

[0021] A first screw rod 6 is provided at the top of the sliding seat 12 and penetrates upward through the gantry 8. A spring 11 is arranged on the first screw rod 6 between the sliding seat 12 and the gantry 8 to elastically support the sliding seat 12 downward, so that the cam 9 is in elastic contact with the surface of the plastic runway. As Figure 1 shown, a first nut 7 is arranged on the first screw rod 6 above the gantry 8 to limit the lowest height of the gantry 8. During the rotation of the cam 9, the sandpaper on the large-diameter section of the outer circle of the cam 9 can contact the surface of the plastic runway, and the sandpaper on the small-diameter section of the outer circle of the cam 9 can be not in contact with the surface of the plastic runway. Moreover, with the rotation of the cam 9, the elastic force is also different, which is beneficial to simulating the change of the foot strength of the exerciser.

[0022] In this embodiment, the cams 9 on both sides rotate out of sync. As Figure 1 shown, the small-diameter section of the outer circle of the left cam faces downward and is not in contact with the surface of the plastic runway, and the sandpaper on the large-diameter section of the outer circle of the right cam is in contact with the surface of the plastic runway to perform the alternating friction detection of the cams on both sides, and the simulation effect is good.

[0023] In this embodiment, the rotating shaft of the motor 10 is perpendicular to the wheel axle of the caster 15. Coupled with the braking function of the caster 15, it can prevent the cart 1 from moving forward when the sandpaper contacts the surface of the plastic runway, and improve the stability during the test.

[0024] In order to improve the moving flexibility, a mobile power source 2 and a controller 3 are arranged on the cart 1. The controller 3 is connected in series between the motor 10 and the mobile power source 2 to supply power for the movement of the motor 10. In addition, a counterweight 16 is arranged on the cart 1 to increase the self-weight of the cart 1 and avoid the shaking problem during the test.

[0025] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
