Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing pad detection technology, in particular to an impact resistance detection platform for shock-absorbing pads. Background Art

[0002] Currently, football fields are all paved with artificial turf. During the laying process of artificial turf, shock-absorbing pads are mostly laid at the bottom of the turf to reduce the risk of athletes falling and getting injured during exercise.

[0003] During the production process of shock-absorbing pads, shock-absorbing pads need to be tested for impact resistance. The impact resistance test is an important test method that can evaluate the resistance of materials or structures to impact. It is a necessary test step to determine whether the shock-absorbing pads can perform normally.

[0004] Currently, impact resistance testing of shock-absorbing pads is usually performed manually, using a detection device to perform a free-fall impact on the surface of the shock-absorbing pad to record the deformation of the surface of the shock-absorbing pad. However, due to large errors in manual operation and the inability to maintain constant test conditions for each test, the test results are not accurate. At the same time, the detection device needs to be manually reset repeatedly during operation before testing again, which makes the detection efficiency low. Utility Model Content

[0009] In addition, a preferred structure is that a control panel is installed on one side of the frame, and the control panel is electrically connected to the drive motor, the pressure sensor module, and the electromagnet suction block respectively.

[0010] In addition, the preferred structure is that a drive box is provided on one side of the frame, and a rack is provided on one side of the interior of the drive box. The rack is connected to a pin gear through a tooth-groove meshing transmission.

[0012] In addition, a preferred structure is that corresponding slots are provided on both sides of the drive box to meet the lifting and lowering operations of the drive motor and the support rod.

[0013] The beneficial effects of the utility model are:

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 A shock-absorbing pad impact resistance testing platform includes a frame 1, a testing platform 2 is installed in the middle of the frame 1, and a plurality of limit plates 7 are installed on the upper part of the testing platform 2 through a slide groove 22, and a support rod 62 is installed above the testing platform 2 through a drive box 5, and an electromagnet suction block 6 is provided on one side of the support rod 62. The bottom of the electromagnet suction block 6 is magnetically connected to a pressure sensing module 61, and the pressure sensing module 61 is directly above the testing platform 2.

[0023] Furthermore, connecting rods 21 are cross-staggeredly arranged in the middle of the testing platform 2, and a sliding groove 22 is opened on one side of the upper part of the connecting rod 21. A limiting plate 7 is installed on the sliding groove 22 through a rubber slider 71 to limit the sliding.

[0024] Furthermore, a control panel 3 is installed on one side of the frame 1 , and the control panel 3 is electrically connected to the driving motor 4 , the pressure sensing module 61 , and the electromagnet suction block 6 .

[0025] Furthermore, a drive box 5 is provided on one side of the frame 1, and a rack 51 is provided on one side of the interior of the drive box 5. The rack 51 is connected to a pin gear 52 through a tooth-groove meshing transmission. One end of the pin gear 52 is connected to the drive motor 4, and the other end is connected to the support rod 62 through a connecting piece.

[0026] Furthermore, a conical limiting groove 8 is provided at the bottom of the electromagnet suction block 6 , an electromagnetic suction component is provided on the top wall of the conical limiting groove 8 , and a pressure sensing module 61 is installed in the conical limiting groove 8 through the conical magnetic block 611 to limit the pressure.

[0027] Furthermore, corresponding slots are provided on both sides of the driving box 5 to meet the lifting and lowering operations of the driving motor 4 and the support rod 62.

[0028] In this embodiment, the shock-absorbing pad to be tested is placed on the testing platform 2 set on the frame 1, and the outer wall of the shock-absorbing pad is clamped and limited by moving the limit plate 7. When it is locked firmly, the driving motor 4 is controlled to rise, and the pressure sensing module 61 connected to it is driven to rise. When it is lifted to the specified height, the electromagnet suction block 6 is powered off, that is, the magnetic force disappears, and the pressure sensing module 61 connected to it falls freely and falls to the middle of the shock-absorbing pad below, and generates impact data.

[0029] Then, during the reset operation, the driving motor 4 drives the electromagnet suction block 6 downward to the pressure sensing module 61. At this time, the electromagnet suction block 6 is energized to generate electromagnetic suction force, and guides the conical magnetic block 611 set on the upper part of the pressure sensing module 61 through the conical limiting groove 8 opened at its bottom, thereby completing the adsorption and connection operation.

[0030] Among them, during actual use, the driving motor 4 rotates and drives the pin gear 52 to rotate through the output shaft, and the pin gear 52 is engaged with the rack 51 in the driving box 5. At the same time, one end of the pin gear 52 is connected to the support rod 62 through a connecting piece. The pin gear 52 will drive the driving motor 4 and the support rod 62 to move synchronously during the rotation and lifting process.

[0031] Among them, during actual use, when the rubber slider 71 drives the limit plate 7 to move, the rubber slider 71 frictionally contacts the inner wall of the slide groove 22, and due to the characteristics of the rubber material, it has a certain damping force when moving, thereby satisfying the free adjustment function of the limit plate 7 and avoiding its displacement.

[0032] In the present utility model, the shock-absorbing pad to be tested is limited by multiple limit plates 7 set on the test platform 2, and the electromagnet suction block 6 is lifted to the corresponding height by the driving motor 4, and the electromagnet is controlled to be powered off so that the pressure sensing module 61 falls freely and collides with the shock-absorbing pad below to generate data, and the driving motor 4 is reset and repeated. During this process, the conical magnetic block 611 and the conical limit groove 8 can increase the recovery efficiency of the pressure sensing module 61, and the device can keep the height and other conditions of each test consistent, effectively avoiding the errors caused by manual detection, and at the same time increasing work efficiency through automatic recovery.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
