The working principle is as follows: when the fixed-point detection device for the pile foundation hole in the civil pile foundation construction is used, firstly, according to the figures 1-3, when the device needs to be positioned and installed, the artificial change of the relative telescopic length of the middle rod 3 and the pressure rod 10 is carried out according to the diameter of the outlet position of the end part of the pile foundation hole 1, as shown in figure 2, under the action of the strip-shaped hole structure on the middle rod 3 and the bolt 11, the change of the relative overlapping length of the middle rod 3 and the pressure rod 10 is carried out, a short telescopic movement space is reserved between the middle rod 3 and the pressure rod 10, and meanwhile, the first elastic piece 12 in the middle rod 3 and the pressure rod 10 acts, so that the middle rod 3 and the pressure rod 10 have good impact damping effect when moving axially relative to each other, as shown in figure 1, the change of the relative overlapping length of the middle rod 3 and the pressure rod 10 enables the distance between the positioning piece 2 and the sliding cylinder 13 to be changed, and the cross-shaped combination and overlapping between the sliding cylinder 13 and the pressure rod 10 can The structure is primarily positioned at the side of a pile foundation hole 1, in order to ensure that the installation of the device is more stable, the impact rod 4 is impacted and impacted by external force, so that the impact rod 4 drives the middle rod 3 to slide in the positioning part 2, the impact force of the impact rod 4 is under the action of the composition structure between the middle rod 3 and the pressure rod 10, the impact shock absorption protection of the device can be effectively carried out through the composition structure, the impact damage of the device is avoided, as shown in figure 3, when the middle rod 3 slides in the positioning part 2, the tooth block structure at the side of the positioning part 2 is meshed with the gear ring 6, so that the gear ring 6 drives the positioning pipe 5 to rotate in the positioning part 2 due to the connection of bearings, the limiting block 9 at the end part of the inner hollow pin 8 is in fit sliding connection with the spiral structure at the bottom of the drilling rod 7, and the drilling rod 7 is in threaded connection with the positioning, the drill rod 7 penetrates through the hollow pin 8 and is drilled into soil to be firmly grabbed, the positioning piece 2 is grabbed and positioned on the ground, and meanwhile, the impact rod 4 drives the middle rod 3 to move towards the sliding barrel 13, so that the distance between the positioning piece 2 and the sliding barrel 13 is enlarged, the effects of grabbing the ground of the device and squeezing type positioning on the inner wall of the outlet of the pile foundation hole 1 are achieved, and fixed-point installation of the device is more stable;
as shown in fig. 1 and 4, when detecting a pile foundation hole 1, the extending pipe 19 and the sliding barrel 13 are slid relatively to change the length of the extending pipe into the pile foundation hole 1, so as to facilitate detection of diameters at different positions in the pile foundation hole 1, and the extending pipe 19 is positioned, as shown in fig. 4, by rotating the screw 18, 2 positioning clamps 17 and the cross rod 15 are slid through and moved relatively, so that the positioning clamps 17 clamp the extending pipe 19, and at the same time, under the action of an elastic extrusion structure arranged between the connecting rod 14 and the outer wall of the sliding barrel 13 and connected by a spring, the end of the connecting rod 14 laterally pulls the cross rod 15 and the positioning clamps 17 through the first rotating shaft 16, the extending pipe 19 in the middle of the positioning clamps 17 is limited for two times, and when adjusting the extending position of the extending pipe 19, the connecting rod 14 is pushed forward only to prevent the extending pipe 19 from being pulled, and the pushing of the connecting rod 14 is released when the vertical position of the extending pipe 19 is changed, the extension pipe 19 can be pulled and positioned conveniently and quickly;
according to fig. 1 and 5-7, when the internal detection of the pile foundation hole 1 is performed, the sawtooth rod 21 is manually pulled to make the sawtooth rod 21 perform the ascending or descending motion in the extending pipe 19, as shown in fig. 5-6, when the sawtooth rod 21 performs the ascending motion in the extending pipe 19, the extending pipe 19 is engaged with the gear shaft 27 to make the extending pipe 19 rotate anticlockwise, when the gear shaft 27 is engaged and rotated, the gear shaft 27 is engaged with the sawtooth strip 28 which is stationary on the outer wall of the extending pipe 19, so that the gear shaft 27 drives the connecting seat 25 to perform the downward movement of the clamping sliding connection with the extending pipe 19, the connecting seat 25 which extends to the lower part of the outer side of the extending pipe 19 is weakly magnetically attracted with the magnetic baffle plate 26 and pressurized to keep relatively stationary, and the connecting seat 25 which extends to the upper part of the outer side of the extending pipe 19 is connected with the magnetic baffle plate 26 to be separated from the downward movement to make the detecting rod 29 and the connecting seat 25 rotate, and, the axial end of the detection rod 29 transversely moves to contact the inner wall of the pile foundation hole 1, the sawtooth rod 21 moves and stands still, the diameter of the pile foundation hole 1 at the position is detected under the action of the scale value 23 on the sawtooth rod 21, similarly, when the sawtooth rod 21 descends in the extension pipe 19, the connecting seat 25 above the outer side of the extension pipe 19 is connected with the magnetic baffle plate 26 in a weak magnetic adsorption mode and is pressurized, the connection seat 25 below the outer side of the extension pipe 19 is connected with the magnetic baffle plate 26 and is separated from the upward movement mode, the detection rod 29 and the connecting seat 25 rotate, the detection rod 29 is folded and overturned again to detect the diameters of different positions in the pile foundation hole 1, the position of the extension pipe 19 does not need to be repeatedly changed, the positioning is carried out after the movement of the sawtooth rod 21, when the data is conveniently read, the limiting pin 22 can be manually pulled under the action of the spring, so that the tip structure at the end part of the limiting pin 22 is clamped with the tooth block structure of, the positioning and changing of the moving position of the saw tooth bar 21 can be facilitated.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
