A connecting rod 25 is fixedly installed on the lower surface of the two first sliding blocks 24, and one end of the connecting rod 25 away from the first sliding block 24 is fixedly connected to the upper surface of the arc-surface limiting plate 21.

[0024] By adopting the above technical solution, by driving the two first sliders 24 to slide toward or away from each other along the inner wall of the first slide groove 23, the two first sliders 24 make the two arc-surface limit plates 21 move toward or away from each other through the two connecting rods 25.

[0028] By adopting the above technical solution, the turntable 27 can be easily rotated through the cooperation of the hexagonal wrench and the hexagonal slot 28, and the turntable 27 causes the double-headed screw 26 to rotate.

[0029] The fixing mechanism 3 includes two L-shaped clamping plates 31, and the inner walls of the two L-shaped clamping plates 31 are fixedly installed with L-shaped protective pads 32.

[0030] By adopting the above technical solution, when the two L-shaped clamping plates 31 are pulled to move toward each other, the two L-shaped clamping plates 31 cause the two second sliders 34 to slide toward each other along the inner wall of the second slide groove 33, and the backward sliding of the two second sliders 34 causes the two telescopic rods 35 and the two telescopic springs 36 to contract. When the pile foundation detector is placed between the two L-shaped clamping plates 31, the extension of the two telescopic rods 35 and the two telescopic springs 36 causes the two second sliders 34 to slide toward each other along the inner wall of the second slide groove 33, and the two second sliders 34 cause the two L-shaped clamping plates 31 to move toward each other, and the two L-shaped clamping plates 31 clamp the detector through the two L-shaped protective pads 32.

[0031] Two side plates 37 are fixedly mounted on one side of the frame plate 13, and pull rods 38 are fixedly mounted on the outer walls of the two L-shaped clamping plates 31. The pull rods 38 penetrate the side plates 37 and are movably connected to the side plates 37. The other ends of the two pull rods 38 are fixedly mounted with handles 39.

[0032] By adopting the above technical solution, by pulling the handle 39 , the handle 39 causes the L-shaped clamping plate 31 to move horizontally through the pull rod 38 .

[0033] The rotating mechanism 4 includes a circular slide rail 41, the inner wall of the circular slide rail 41 is fixedly connected to the outer wall of the fixed ring 12, the outer wall of the circular slide rail 41 is slidably connected to two arc-shaped sliders 42, one side of an arc-shaped slider 42 is fixedly installed with two fixing rods 43, one end of the two fixing rods 43 away from one arc-shaped slider 42 is fixedly connected to the other side of the frame plate 13, and a circular gear ring 44 is fixedly installed on the lower surface of the two arc-shaped sliders 42, and the circular gear ring 44 and the circular slide rail 41 are coaxial.

[0034] By adopting the above technical solution, by driving the circular gear ring 44 to rotate, the circular gear ring 44 causes the arc-shaped slider 42 to slide along the axis of the circular slide rail 41 as the center of the circle, and the arc-shaped slider 42 causes the installed detector to rotate around the axis of the circular slide rail 41 as the center of the circle through the fixing rod 43 and the frame plate 13.

[0035] A first motor 45 is fixedly installed on the inner wall of the fixed ring 12, a first fixed block 46 is fixedly installed on the outer wall of the first motor 45, one side of the first fixed block 46 is fixedly connected to the inner wall of the fixed ring 12, a rotating rod 47 is fixedly installed on the driving output end of the first motor 45, a gear 48 is fixedly installed on the end of the rotating rod 47 away from the first motor 45, and the gear 48 is meshingly connected with the circular gear ring 44.

[0036] By adopting the above technical solution, by turning on the first motor 45 , the driving shaft of the first motor 45 causes the rotating rod 47 to rotate, the rotating rod 47 causes the gear 48 to rotate, and the gear 48 drives the circular gear ring 44 to rotate.

[0037] The retracting and unwinding mechanism 5 includes two rotating shafts 51, both ends of the two rotating shafts 51 are rotatably connected to the equipment box 11, the outer walls of the two rotating shafts 51 are fixedly installed with winding rollers 52, the outer walls of the two winding rollers 52 are wound with cables 53, and the winding directions of the two cables 53 are opposite, and the outer wall of the top cover 1 is fixedly installed with two guide plates 54, a cable 53 passes through a guide plate 54 and is movably plugged with a guide plate 54, one end of the cable 53 away from the winding roller 52 is fixedly connected to the upper surface of the fixing ring 12, one end of the two rotating shafts 51 is fixedly installed with a synchronous wheel 55, and a synchronous belt 56 is transmission-connected between the two synchronous wheels 55.

[0038] By adopting the above technical solution, by driving a rotating shaft 51 to rotate, one rotating shaft 51 makes the other rotating shaft 51 rotate synchronously in the same direction through two synchronous wheels 55 and a synchronous belt 56, and the two rotating shafts 51 make the two cables 53 unwind or reel through two winding rollers 52. By setting a guide plate 54, the guide plate 54 limits the cable 53 during the unwinding and reeling process, and the unwinding and reeling of the cable 53 causes the fixed ring 12 to rise or fall.

[0041] Working principle: when it is necessary to inspect the foundation pile, the staff first pulls the two handles 39 in opposite directions at the same time. The two handles 39 separate the two L-shaped clamping plates 31 in opposite directions through the two pull rods 38. The two L-shaped clamping plates 31 make the two second sliders 34 slide in opposite directions along the inner wall of the second slide groove 33. The opposite sliding of the two second sliders 34 makes the two telescopic rods 35 and the two telescopic springs 36 contract. Then the pile foundation detector is placed between the two L-shaped clamping plates 31, and the detection end of the pile foundation detector faces the axial direction of the fixing ring 12. At this time, the two handles 39 are released, the two telescopic rods 35 and the two telescopic springs 36 are extended, and the two second sliders 34 slide in opposite directions along the inner wall of the second slide groove 33. The two second sliders 34 make the two L-shaped clamping plates 31 move in opposite directions. The two L-shaped clamping plates 31 clamp the pile foundation detector through the two L-shaped protective pads 32, thereby conveniently realizing the fixed installation of the pile foundation detector, thereby effectively improving the convenience of installing the pile foundation detector. Subsequently, the staff makes the fixing ring 12 sleeved on the outer wall of the pile, and the inner wall of the fixing ring 12 contacts the outer wall of the pile. At this time, the top cover 1 is sleeved on the top of the pile. Then, the hexagonal wrench and the hexagonal slot 28 are cooperated to rotate the turntable 27, and the turntable 27 rotates the double-headed screw 26. While the double-headed screw 26 rotates, the two first sliders 24 slide toward each other along the inner wall of the first slide groove 23. The two first sliders 24 move the two arc-surface limit plates 21 toward each other through the two connecting rods 25 until the outer walls of the two arc-surface anti-skid pads 22 are in close contact with the top outer wall of the pile. Then, the rotation of the turntable 27 is stopped. At this time, the two arc-surface limit plates 21 fix the top cover 1 to the top of the pile through the two arc-surface anti-skid pads 22, thereby conveniently realizing the fixed connection between the top cover 1 and the top of the pile, and then facilitating the subsequent detection of the pile. At this time, the staff turns on the first motor 45, the driving shaft of the first motor 45 rotates the rotating rod 47, the rotating rod 47 rotates the gear 48, the gear 48 drives the circular gear ring 44 to rotate, the circular gear ring 44 makes the two arc-shaped sliders 42 slide along the axis of the circular slide rail 41 as the center of the circle, the two arc-shaped sliders 42 make the installed detector rotate around the axis of the circular slide rail 41 as the center of the circle through the two fixing rods 43 and the frame plate 13, and the pile detector detects the outer wall of the pile; After a circle of detection contact of the pile foundation, the staff turns on the second motor 57, and the driving shaft of the second motor 57 rotates the corresponding rotating shaft 51, and one rotating shaft 51 rotates synchronously in the same direction through two synchronous wheels 55 and a synchronous belt 56, and the two rotating shafts 51 unwind the two cables 53 through two winding rollers 52, and the unwinding of the two cables 53 causes the fixing ring 12 to descend, and the fixing ring 12 causes the installed pile foundation detector to descend synchronously through the frame plate 13, until the height of the pile foundation detector after vertical descent is adapted to the height required for the detection operation, and then the second motor 57 is turned off, thereby conveniently realizing the self-rotation and height adjustment of the pile foundation detector, and then facilitating the staff to conduct all-round detection of the pile foundation.
