[0027] The working principle of the hole detector in the above technical solution is as follows:

[0028] In the process of detecting the diameter of the pile, first, the whole device is lowered into the pile hole by the crane and the lifting ring, and in the process of lowering, the distance between the detection rod 3 and the main shaft 24 can be adjusted according to the diameter of the pile hole. In the adjustment process:

[0029] First, pull one of the first connecting rods 31 to move the sliding sleeve 32 connected by the first connecting rod 31 upwards or downwards, and the support rod 21 is synchronously driven during the movement. Until the diameter of the pile hole is adjusted to the same size, the sliding rod 22 is fixed with the limiting protrusion 23, and the rope is fixed in the connecting port 33a before lowering by the crane. The distributed detection rods 3 are connected by the rope, and then the connecting port 33a is pulled upwards. After the connecting port 33a is pulled, the connecting rope 33b drives the connecting seat 33c to swing upwards along the mounting seat 33d. At this time, the roller 33e is exposed in the straight slot of the rod body 33, and the included angle between the lower swing foot 36 and the connecting base 35 is kept between 45°-60°. The successful lowering of the hole detector can effectively avoid the contact and wear of the side surface of the detection rod;

[0030] When the hole detector completes the detection work, it is taken out. When taking out, the lower swing foot 36 is first received in the inside of the containing groove 5b1, the electric telescopic rod 35d is started, and the lower swing foot 36 is pressed to the movable plug body 5b5 at the same time when the electric telescopic rod 35d is retracted. The movable plug body 5b5 is compressed towards the inside of the communication pipe 5b4. In the compression process, the gas in the communication pipe 5b4 is output on the partition plate 5b3, driving the partition plate 5b3 to advance along the inside of the containing groove 5b1, and in turn driving the electric telescopic rod 35d to move synchronously. The lower swing foot 36 is better received in the containing groove 5b1. In this way, when the connecting base 35 is placed on the ground, it can be more stable, and the hole detector is not easy to fall over.
