8. The airport runway skid resistance detection apparatus of claim 1, wherein: the lower end of the support column is provided with a lifting assembly and a lifting knob, and the lifting assembly is configured to adjust the height of the support column by screwing the lifting knob.
9. The airport runway skid resistance detection apparatus of claim 1, wherein: the first pendulum bob and the second pendulum bob respectively comprise a balancing weight, and a friction pad is arranged on the balancing weight so as to be in contact with the ground when the balancing weight swings to the lower part along with the first swing rod or the second swing rod and slide for a preset distance along with the balancing weight.
10. The detection method of the airport runway skid resistance detection apparatus as claimed in any of claims 1 to 9, characterized in that: the method comprises the following steps:
(1) after the anti-skid performance detection device of the airport runway is placed on a road surface to be detected, the first swing ring and the second swing ring are connected through a connecting bolt, and the connecting bolt is positioned under the vertical groove by adjusting the liftable ground feet;
(2) rotating the lifting knob to adjust the height of the support and rotating the second oscillating bar to enable the friction pad of the second pendulum bob to slide on the ground for a preset distance;
(3) and rotating the trigger switch to enable the connecting bolt to be separated from the first swing ring and the second swing ring, wherein the first swing rod and the second swing rod respectively swing downwards and oppositely under the action of gravity and simultaneously drive the first pointer and the second pointer to rotate, the first swing rod and the second swing rod fall back after rotating to the highest positions, vertical surfaces of the first wedge block and the second wedge block push against each other in the falling process, and the first swing rod and the second swing rod stop moving.
(4) Recording scale values of the staying positions of the first pointer and the second pointer;
(5) loosening the first wedge block and the second wedge block to enable the first swing rod and the second swing rod to return to the initial positions, and rotating the trigger switch to enable the connecting bolt to be connected with the first swing ring and the second swing ring; the first pointer and the second pointer are dialed back to the initial positions;
(6) and (5) repeating the steps (3) to (5) to obtain a plurality of scale values, and calculating the average value of the scale values.
