the first motor 305 is started to move the automatic unhooking device 311 downwards and connect the automatic unhooking device 311 with the adapter block 408, after connection, the first motor 305 is started to lift the loading box 401 until the loading box 401 is separated from the cushion block 103, and the locking screw is unscrewed to enable the adjusting block 410 to be turned downwards until the locking screw 411 is located at the bottom of the through groove two 412, for example: the solid block 414 angle can be divided into six gears of 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees and 30 degrees, and when the polyurethane buffer is required to be measured and no inclination angle impact exists, the 30-degree solid block 414 is placed on the adjusting block 410; when the impact with the inclination angle of the polyurethane buffer of 5 degrees is required to be measured, a 25-degree solid block 414 is placed on the adjusting block 410, and the like, when the impact with the inclination angle of the polyurethane buffer of 30 degrees is required to be measured, the solid block 414 is not required to be placed, and then the locking screw 411 is screwed down;
different numbers of weights 402 can be placed inside the loading box 401 according to measurement, the weight of each weight 402 is standard and the same, the weight of each weight 402 can be designed according to the measured index, the loading box 401 is weighed by the weight on the automatic unhooking device 311, after the weight reaches a preset value, the first motor 305 is started to drive the loading box 401 to move upwards to a preset height, when the impact force corresponding to the measured polyurethane buffer is below the top plate 107, the automatic unhooking device 311 can be directly separated from the adapter 408, so that the loading box 401 can do free-falling motion to perform impact force experiments on the polyurethane buffer;
when the height required for measuring the impact force of the polyurethane buffer exceeds the height of the top plate 107, when the loading box 401 is in free falling, the propeller 202 is started, the motor II 504 is started at the same time, the propeller 202 can apply a downward pressure to the loading box 401 through the contact plate 201, so that the downward movement acceleration of the loading box 401 is larger than the gravity acceleration, and the motor II 504 can drive the opposite-impact plate 501 and the propeller 202 to move downwards along with the acceleration structure 2 at a certain distance through the roller 512, so that the thrust of the propeller 202 is kept stable.
Before the polyurethane buffer body 104 is impacted, the corresponding solid block 414 can be installed on the slope 105 according to the inclination angle of the adjusting block 410, so that the adjusting block 410 can avoid the slope 105 from damaging the adjusting block 410 when the polyurethane buffer body 104 is impacted.
The invention and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the invention as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present invention.
