Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0023] As Figure 1 shown, a turf testing tooling for a stadium includes a mounting frame 1. The turf is laid on the upper surface of the mounting frame 1, and two pressing plate assemblies 2 are arranged at the upper end of the mounting frame 1 to press and fix the turf on the mounting frame 1.

[0024] As Figure 2 shown, the pressing plate assembly 2 includes a fixing frame 21 fixed to the upper end of the mounting frame 1. A pressing plate 22 is arranged on the fixing frame 21. At least two guide rods 23 are arranged at the upper end of the pressing plate 22. The guide rods 23 penetrate through the fixing frame 21 along the vertical direction and are slidably connected with the fixing frame 21. An adjusting rod 24 is arranged on the fixing frame 21. The adjusting rod 24 penetrates through the fixing frame 21 along the vertical direction and is threadedly connected with the fixing frame 21. The end of the adjusting rod 24 is rotatably connected with the pressing plate 22. By rotating the adjusting rod 24, the lifting movement of the pressing plate 22 can be controlled, so that the turf can be pressed tightly on the upper end of the mounting frame 1 to facilitate the tensile test of the turf.

[0025] It is worth mentioning that in this embodiment, the adjusting rod 24 needs to have a self-locking ability, that is, the thread lead angle of the adjusting rod 24 is less than the equivalent friction angle to ensure the stable pressing and fixing of the turf.

[0026] Of course, the ways to drive the lifting of the pressing plate 22 include but are not limited to the structure of the adjusting rod 24 in this embodiment. In some embodiments, a linear driving component such as a cylinder and a telescopic rod can also be arranged on the fixing frame 21 to directly drive the lifting of the pressing plate 22, and the turf can also be pressed tightly on the upper end of the mounting frame 1.

[0027] An installation plate 11 is fixed to each side of the upper end of the mounting frame 1. A flipping frame 3 is arranged on the installation plate 11. A rotating shaft 31 is fixed to each side of the flipping frame 3. The two rotating shafts 31 are coaxial and are respectively rotatably connected with the two installation plates 11, so that the flipping frame 3 can be flipped around the rotating shaft 31. A hydraulic cylinder 4 is arranged at the upper end of the flipping frame 3. A connecting plate 5 is fixed to the end of the driving shaft of the hydraulic cylinder 4. A spring dynamometer 6 is fixed to the connecting plate 5. A clamping component 7 is installed on the lower hook of the spring dynamometer 6. The clamping component 7 can clamp the grass on the turf, and under the drive of the hydraulic cylinder 4, a pulling force is applied to the turf. By reading the value on the spring dynamometer 6, the pulling force applied to the turf can be judged, and by controlling the flipping of the flipping frame 3, the adjustment of the pulling force angle of the turf can be realized.

[0028] As Figure 3 and Figure 4 shown, the clamping assembly 7 includes a support plate 71. A connecting frame 72 is fixed to the upper end of the support plate 71. A hanging ring 73 is fixed to the upper end of the connecting frame 72. The hanging ring 73 cooperates with the hook on the spring dynamometer 6 to transmit the pulling force to the clamping assembly 7 and even to the turf;

[0029] Two clamping plates 74 are slidably connected to the lower end of the support plate 71. Two fixing plates 711 are fixed to the support plate 71. A lead screw 75 is rotatably connected between the two fixing plates 711. First external threads 751 and second external threads 752 are respectively arranged at both ends of the lead screw 75. The first external thread 751 and the second external thread 752 have opposite helix directions and respectively penetrate through the two clamping plates 74 and are threadedly connected to the clamping plates 74. By arranging a motor on one of the fixing plates 711 to drive the lead screw 75 to rotate, the two clamping plates 74 can be made to approach each other, thereby realizing the clamping and fixing of the grass on the turf;

[0030] Of course, the way to drive the two clamping plates 74 to approach each other includes but is not limited to the lead screw 75 and other structures in this embodiment. In some embodiments, two cylinders can also be arranged on the support plate 71 to respectively drive the two clamping plates 74 to approach each other, and the grass on the turf can also be clamped and fixed.

[0031] In this embodiment, by arranging a driving assembly 8 on one of the mounting plates 11, the flipping frame 3 is driven to flip around the rotating shaft 31 to achieve the purpose of applying an inclined pulling force to the turf;

[0032] As Figure 5 shown, the driving assembly 8 includes a first gear 81 fixed on one of the rotating shafts 31. A motor 82 is fixed to the mounting plate 11. A second gear 83 is fixed on the driving shaft of the motor 82. The second gear 83 meshes with the first gear 81. Driven by the motor 82, the flipping frame 3 can be driven to tilt and flip around the rotating shaft 31;

[0033] Of course, the structure of the driving assembly 8 includes but is not limited to the gear meshing structure in this embodiment. In some embodiments, the driving assembly 8 can also directly be a motor. The motor is installed on the mounting plate 11 and directly drives the rotating shaft 31 to rotate, and the flipping frame 3 can also be driven to tilt and flip around the rotating shaft 31.

[0034] Working principle:

[0035] By setting two pressing plate assemblies 2 on the mounting frame 1 to press both ends of the turf tightly against the surface of the mounting frame 1, and arranging a turning frame 3 that can rotate around the rotating shaft 31 between the two mounting plates 11, a spring tensiometer 6 that can be lifted and lowered is arranged on the turning frame 3 to pull the clamping assembly 7, and the tensile force is transmitted from the clamping assembly 7 to the turf, so as to realize the test of the tensile property of the turf. By controlling the turning and tilting of the turning frame 3, the adjustment of the tensile angle of the turf can be realized, thereby improving the reliability of the test results.
