[0002] Drilling is an important step in the construction of bridge pile foundations. A drilling machine is used to drill vertical pile holes in the ground to facilitate the subsequent pouring of the pile.
[0003] When drilling, the verticality of the drill rod needs to be calibrated to avoid borehole deviation. Once the borehole is deviated, it will affect the stability of the pile foundation and may also damage the drill rod. The current calibration method is to use a bubble level to measure the verticality of the drill rod manually. The inspection process is cumbersome and time-consuming. After the test results are recorded, fine-tuning is performed, and then calibration is performed again. The whole process is time-consuming and does not have the function of easy online monitoring and correction.

[0008] As a further technical solution of this utility model, the shape and size of the inside of the sensor fixing sleeve are adapted to the shape and size of the outside of the side sensor fixing rod, and the sensor fixing sleeve can slide back and forth along the outside of the side sensor fixing rod.
[0009] As a further technical solution of this utility model, the first laser rangefinder and the second laser rangefinder have the same specifications, and the two sets of the first laser rangefinders are positioned opposite each other.
[0010] As a further technical solution of this utility model, the upper and lower ends of the first laser rangefinder and the second laser rangefinder are flush, and the PLC controller, the first laser rangefinder, the second laser rangefinder, the speaker, and the three-color alarm light are electrically connected.
[0011] As a further technical solution of this utility model, the lifting plate has multiple sets of positioning screw holes inside. The bottom ends of the side sensor fixing rod and the central sensor fixing rod are respectively vertically welded with two sets of positioning screws. Locking nuts are sleeved on the outside of the positioning screws. A hand-tightening bolt is inserted into the top of the sensor fixing sleeve.

A counterweight is fixedly connected to the bottom of the right side of the lifting plate. Two sets of limiting optical shafts are vertically fixedly connected inside the main fixing frame. A ball screw lever is vertically movably connected between the upper and lower ends inside the main fixing frame. A servo motor is installed at the bottom inside the main fixing frame. The thread inside the ball screw nut matches the thread outside the ball screw lever.

The output end of the servo motor is connected to the bottom end of the ball screw lever. The limiting optical shaft passes through the inside of the optical shaft through hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the bridge pile foundation drilling verticality calibrator with correction function not only realizes the function of easy online monitoring and correction, but also realizes the function of adjustable sensor position and adjustable detection height;
[0014] (1) By setting up a lifting plate, side sensor fixing rod, sensor fixing sleeve, first laser ranging sensor, central sensor fixing rod, second laser ranging sensor, speaker and three-color alarm light, when in use, the bottom fixing plate is fixed to the drilling platform by bolts, the main fixing frame is located on the side of the drill rod, the lifting plate is located behind the drill rod, the second laser ranging sensor on the central sensor fixing rod measures the position behind the drill rod, and the first laser ranging sensor on the side sensor fixing rod measures the position on both sides of the drill rod.

Loosening the hand-tightening bolt, since the hand-tightening bolt and the top of the sensor fixing sleeve are threadedly connected, its bottom is pressed against the side sensor fixing rod when it is tightened. As the hand-tightening bolt is loosened, its bottom and the side sensor fixing rod are separated from each other, and the sensor fixing sleeve can slide back and forth along the side sensor fixing rod. Then, by tightening the hand-tightening bolt again, the position of the sensor fixing sleeve on the side sensor fixing rod can be adjusted, thereby adjusting the position of the first laser ranging sensor, realizing the function of adjustable sensor position.

[0025] Please see Figure 1-5 A bridge pile foundation drilling verticality calibrator with a correction function also includes a correction component. The correction component includes two sets of side sensor fixing rods 5. The two sets of side sensor fixing rods 5 are installed on the top of the lifting plate 4. A sensor fixing sleeve 6 is sleeved on the outside of the side sensor fixing rods 5. A first laser rangefinder 7 is fixedly connected to the bottom of the sensor fixing sleeve 6.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the bottom fixing plate 1 is fixed to the drilling platform with bolts, the main fixing frame 3 is located on the side of the drill rod, the lifting plate 4 is located behind the drill rod, the second laser range sensor 9 on the central sensor fixing rod 8 measures the position behind the drill rod, and the first laser range sensor 7 on the side sensor fixing rod 5 measures the position on both sides of the drill rod. When the drill rod deviates, the three sets of range sensors can quickly detect the change in distance, the three-color alarm light 22 sounds an alarm, and at the same time the speaker 21 broadcasts a voice message according to the distance of the deviation. The staff makes fine adjustments according to the broadcast voice message until the voice message is completely vertical.
[0028] The lifting plate 4 has multiple sets of positioning screw holes 11 inside. The bottom ends of the side sensor fixing rod 5 and the central sensor fixing rod 8 are vertically welded with two sets of positioning screws 12. The positioning screws 12 are fitted with locking nuts 10. The top of the sensor fixing sleeve 6 is inserted with a hand-tightening bolt 13. The positions and dimensions of the positioning screw holes 11 and the positioning screws 12 are one-to-one. The positioning screws 12 pass through the inside of the positioning screw holes 11. The top of the sensor fixing sleeve 6 is threaded inside. The threads inside the sensor fixing sleeve 6 match the threads outside the hand-tightening bolt 13, which facilitates the adjustment of the sensor position.
[0029] Specifically, such as Figure 2 and Figure 3 As shown, the position of the first laser rangefinder 7 can be adjusted according to the specifications and dimensions of the drill rod. By inserting the positioning screw 12 into the positioning screw hole 11 at different positions, the distance between the two sets of first laser rangefinders 7 can be adjusted. Loosen the hand-tightening bolt 13. Since the hand-tightening bolt 13 is threadedly connected to the top of the sensor fixing sleeve 6, its bottom is pressed against the side sensor fixing rod 5 when it is tightened. As the hand-tightening bolt 13 is loosened, its bottom and the side sensor fixing rod 5 are separated from each other, and the sensor fixing sleeve 6 can slide back and forth along the side sensor fixing rod 5. Then, tighten the hand-tightening bolt 13 again to adjust the position of the first laser rangefinder 7.

The internal thread of the ball screw nut 15 matches the external thread of the ball screw lever 19. The inner diameter of the optical shaft through hole 16 is the same as the outer diameter of the limiting optical shaft 18. The ball screw lever 19 passes through the inside of the ball screw nut 15. The output end of the servo motor 20 is connected to the bottom end of the ball screw lever 19. The limiting optical shaft 18 passes through the inside of the optical shaft through hole 16, which facilitates the adjustment of the sensor working height.
[0031] Specifically, such as Figure 1 and Figure 4 As shown, the working height of the sensor can be adjusted according to the height of the drill rod. The servo motor 20 drives the ball screw lever 19 to rotate. The ball screw lever 19 and the ball screw nut 15 inside the slider 14 cooperate to drive the slider 14 and the lifting plate 4 to move up and down. The optical axis through hole 16 and the limiting optical axis 18 cooperate to make the up and down movement smooth. The counterweight 17 can prevent the lifting plate 4 from tilting.

When the drill rod deviates, the three sets of range sensors can quickly detect the change in distance, the three-color alarm light 22 sounds an alarm, and at the same time the speaker 21 broadcasts a voice message according to the distance of the deviation. The staff makes fine adjustments according to the broadcast voice message until the voice message is completely vertical. The position of the first laser rangefinder 7 can be adjusted according to the specifications and dimensions of the drill rod. By inserting the positioning screw 12 into the positioning screw holes 11 at different positions, the distance between the two sets of first laser rangefinders 7 can be adjusted. Loosening the hand-tightening bolt 13, since the hand-tightening bolt 13 is threadedly connected to the top of the sensor fixing sleeve 6, its bottom is pressed against the side sensor fixing rod 5 when it is tightened. As the hand-tightening bolt 13 is loosened, its bottom and the side sensor fixing rod 5 are separated from each other, and the sensor fixing sleeve 6 can slide back and forth along the side sensor fixing rod 5. Then, by retightening the hand-tightening bolt 13, the position of the sensor fixing sleeve 6 on the side sensor fixing rod 5 can be adjusted, thereby adjusting the position of the first laser rangefinder 7. The working height of the sensor can be adjusted according to the height of the drill rod. The servo motor 20 drives the ball screw lever 19 to rotate. The ball screw lever 19 and the ball screw nut 15 inside the slider 14 cooperate to drive the slider 14 and the lifting plate 4 to move up and down. The optical axis through hole 16 and the limiting optical axis 18 cooperate to make the up and down movement smooth. The counterweight 17 can prevent the lifting plate 4 from tilting.
