The telescopic ends of the two hydraulic cylinders 402 are fixedly mounted with a dust box 401. A drilling assembly 5 is provided below the dust box 401. The drilling assembly 5 consists of a dust suction mechanism and a drilling mechanism and is used to absorb dust generated when drilling holes in the pile foundation 2. The lower surface of the dust box 401 is connected to the dust suction mechanism. The upper surface of the dust box 401 is located between the two hydraulic cylinders 402 and is equipped with a dust suction pump 4 through bolts. 03, the suction port of the dust suction pump 403 is connected with the interior of the dust box 401, the outer walls of the two hydraulic cylinders 402 and the dust suction pump 403 are sleeved with a mounting plate 7, the outer walls of both sides of the mounting plate 7 are welded with limiting plates 701, the inner wall tops of the two vertical plates 102 are provided with limiting grooves 1022, the ends of the two limiting plates 701 are located in the limiting grooves 1022 and are slidably connected thereto, and the control panel 105 is electrically connected with the electric slide rail 1031, the dust suction pump 403, the drilling assembly 5 and the rotating assembly 8; A horizontal plate 3 is welded between the two vertical plates 102 and located above the support block 101. An upper arc plate 301 is provided at the center below the two horizontal plates 3. The arc surfaces of the two upper arc plates 301 are connected to the upper surface of the pile foundation 2. A plurality of balls are embedded in the arc surfaces of the two upper arc plates 301. A threaded rod 302 is rotatably installed at the center of the upper surface of the two upper arc plates 301. The top end of the threaded rod 302 passes through the horizontal plate 3 and is fixed with a rotating handle 304. Guide rods 303 are penetrated on both sides of the threaded rod 302 on the horizontal plate 3. The bottom ends of the two guide rods 303 are fixedly connected to the two ends of the upper surface of the upper arc plate 301.

[0024] When splicing the pile foundation 2 of the highway bridge, it is necessary to drill holes in the splicing part for installing the embedded parts or bolts thereon. At this time, the staff first places the pile foundation 2 horizontally and moves it laterally, so that the pile foundation 2 is located in the arc groove 1011 on the two support blocks 101, and the rolling cylinder 1012 contacts the surface of the pile foundation 2. Then the staff manually turns the rotary handle 304, and the rotary handle 304 drives the threaded rod 302 to rotate. The threaded rod 302 moves downward along the cross plate 3 through the bolts, so that the upper arc plate 301 moves following the rotation of the threaded rod 302 under the restriction of the guide rod 303, and the guide rod 303 slides along the cross plate 3 until the arc surface of the upper arc plate 301 contacts the surface of the pile foundation 2, and cooperates with the arc groove 1011 to achieve the function of clamping and fixing, wherein the ball of the upper arc plate 301 contacts the surface of the pile foundation 2; Then the staff starts the electric slide rail 1031 through the control panel 105, and observes the movement of the sliding seat 4 in real time through the transparent window 1021. The sliding seat 4 drives the drilling assembly 5 to move above the drilling position of the pile foundation 2 through the two hydraulic cylinders 402. When the two hydraulic cylinders 402 move, the mounting plate 7 and the limiting plate 701 will move. The two limiting plates 701 will slide along the limiting groove 1022, and the two limiting plates 701 can start the suspended support of the entire drilling assembly 5. Then, the dust suction pump 403, the two hydraulic cylinders 402 and the drilling assembly 5 are started through the control panel 105. The driving part of the drilling mechanism in the hole assembly 5, the dust suction pump 403 works to generate negative pressure in the dust box 401, and acts on the actuator of the dust suction mechanism in the drilling assembly 5. At this time, the telescopic ends of the two hydraulic cylinders 402 push the dust box 401 to move downward, so that the dust box 401 drives the drilling assembly 5 to move downward, and the actuator end of the dust suction mechanism contacts the upper surface of the pile foundation 2. Under the continuous operation of the hydraulic cylinder 402, the dust suction mechanism shrinks, and the drilling mechanism performs drilling construction on the surface of the pile foundation 2. The generated dust is sucked into the dust box 401 by suction and attached to the dust collecting bag 9, completing the drilling of the pile foundation 2; When it is necessary to drill holes on other surfaces of the pile foundation 2, the staff starts the actuator of the rotating assembly 8 through the control panel 105, which can control the two rolling cylinders 1012 to rotate. The rotation of the two rolling cylinders 1012 drives the pile foundation 2 to rotate through friction with the surface of the pile foundation 2, wherein the surface of the rolling cylinder 1012 can be provided with a friction layer to increase friction, and at the same time, the upper arc plate 301 and the plurality of balls on the driving shell 104 can cooperate with the rolling cylinder 1012 to rotate the pile foundation 2, so that the other surfaces of the pile foundation 2 rotate to the upper side and below the drilling assembly 5, and then repeat the above-mentioned drilling operation to perform drilling construction; Therefore, the present application can cover the drilling site and absorb the generated dust when drilling the pile foundation 2 to prevent it from scattering to the surroundings, reducing the steps of manual cleaning, and can automatically flip the pile foundation 2 to improve the adaptability of the drilling construction.

[0026] The driving motor 5021 of the drilling assembly 5 works together with the dust suction pump 403 and the two hydraulic cylinders 402. The output end of the driving motor 5021 drives the connected drill rod 5022 to rotate. When the telescopic ends of the two hydraulic cylinders 402 push the dust box 401 downward, the dust box 401 drives the dust suction pump 403, the square tube 501, the telescopic tube 5011 and the arc-shaped pipe mouth 5012 to move downward until the tooth surface of the arc-shaped pipe mouth 5012 contacts the surface of the pile foundation 2. The setting of the tooth surface can avoid the arc-shaped pipe mouth 5012 from contacting the surface of the pile foundation 2. The dust collecting box 401 is sealed to facilitate the suction to absorb the dust. At this time, as the hydraulic cylinder 402 continues to work, the dust collecting box 401 will drive the square tube 501 to continue to move downward. The downwardly moving square tube 501 will squeeze the telescopic tube 5011, causing the telescopic tube 5011 to shrink, and will also shrink the two telescopic rods 601 and squeeze the supporting spring 602. At this time, the fixed block 502 will move with the square tube 501, so that the rotating drill rod 5022 will contact the surface of the pile foundation 2 through the arc-shaped pipe mouth 5012 and perform drilling construction. The dust generated by drilling enters the telescopic tube 5011 and the square tube 501 through the suction at the arc-shaped pipe mouth 5012, enters the dust box 401 from both sides of the fixed block 502 through the valve 504 opened upward due to the suction, and adheres to the dust collecting bag 9.

[0029] The working principle of the present invention is: When splicing the pile foundation 2 of the highway bridge, it is necessary to drill holes in the splicing part for installing the embedded parts or bolts thereon. At this time, the staff first places the pile foundation 2 horizontally and moves it laterally, so that the pile foundation 2 is located in the arc groove 1011 on the two support blocks 101, and the rolling cylinder 1012 contacts the surface of the pile foundation 2.

The sliding seat 4 drives the drilling assembly 5 to move above the drilling position of the pile foundation 2 through the two hydraulic cylinders 402. When the two hydraulic cylinders 402 move, the mounting plate 7 and the limiting plate 701 are driven to move. The two limiting plates 701 slide along the limiting groove 1022. Then the dust suction pump 403, the two hydraulic cylinders 402 and the driving motor 5021 are started through the control panel 105. The operation of the dust suction pump 403 generates negative pressure in the dust box 401, and suction is generated at the arc-shaped pipe mouth 5012 through the square tube 501 and the telescopic tube 5011. The output end of the driving motor 5021 drives the connected drill rod 5022 to rotate When the telescopic ends of the two hydraulic cylinders 402 push the dust box 401 downward, the dust box 401 will drive the dust suction pump 403 and the square tube 501, the telescopic tube 5011 and the arc-shaped pipe mouth 5012 to move downward until the tooth surface of the arc-shaped pipe mouth 5012 contacts the surface of the pile foundation 2. At this time, as the hydraulic cylinder 402 continues to work, the dust box 401 will drive the square tube 501 to continue to move downward, and the downward moving square tube 501 will squeeze the telescopic tube 5011, causing the telescopic tube 5011 to shrink, and will also shrink the two telescopic rods 601 and squeeze the support spring 602. At this time, the fixed block 502 will move with the square tube 501, so that the rotating drill rod 5022 contacts the surface of the pile foundation 2 through the arc-shaped pipe mouth 5012 and performs drilling construction; The dust generated by drilling enters the telescopic tube 5011 and the square tube 501 through the suction force at the arc-shaped tube opening 5012, and enters the dust box 401 from both sides of the fixed block 502 through the valves 504 opened upward due to the suction force, and adheres to the dust collecting bag 9; When it is necessary to drill holes on other surfaces of the pile foundation 2, the staff starts the fixed motor 806 of the rotating assembly 8 through the control panel 105, and the output end of the fixed motor 806 drives the rotating shaft 807 to rotate, and the rotating shaft 807 drives the driving sprocket 808 to rotate, and the driving sprocket 808 drives the driven sprockets 805 on both sides to rotate through the transmission chain 809, and the two driven sprockets 805 drive the shaft rod 804 to rotate, and the connected worm 803 is driven to rotate through the rotating shaft rod 804, and the two worm 803 drives the meshing The worm gear 802 rotates, so that the two worm gears 802 drive the transmission shaft 801 to rotate. The rotating transmission shaft 801 transmits the rotational force to the rolling cylinders 1012 at both ends, so that the rolling cylinders 1012 rotate and drive the pile foundation 2 to rotate through friction. At the same time, the upper arc plate 301 and several balls on the drive shell 104 can cooperate with the rolling cylinders 1012 to rotate the pile foundation 2, so that the other surfaces of the pile foundation 2 rotate to the upper side and below the drilling assembly 5, and then repeat the above drilling operation to carry out drilling construction.
