Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, specifically to an integrated positioning and driving jet grouting drilling rig. Background Technology

[0002] Jet grouting piles utilize a drilling rig to place the jet grouting pipe and nozzle at the designed elevation at the bottom of the pile. Pre-prepared grout is injected with high-pressure energy by a high-pressure generator and then ejected at high speed from the nozzle on the side of the grouting pipe, forming a highly concentrated stream of liquid that directly disrupts the soil. During the injection process, the drill rod rotates and is lifted, allowing the grout to be fully mixed with the soil, forming a columnar solidified body of a certain diameter in the soil, thereby reinforcing the foundation.

[0003] Before constructing existing high-pressure jet grouting piles, control points are determined using a total station, marked with embedded stones, and after verification of the survey lines, pile positions are laid out on-site using steel rulers and survey lines, secured with bamboo sticks—one stick per pile—to ensure the center displacement deviation of the pile hole is less than 50mm. However, the on-site construction environment is often complex, and using bamboo sticks to temporarily determine pile positions often results in deviations and is prone to loss, requiring re-measurement of the pile position. Secondly, existing high-pressure jet grouting pile drilling rigs are often too large. When construction needs to be carried out in confined spaces, such as under bridges, smaller high-pressure jet grouting pile drilling rigs are often chosen. However, most small high-pressure jet grouting pile drilling rigs lack a drive mechanism, requiring manual operation, which is time-consuming and labor-intensive. Summary of the Invention

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figure 1 As shown, an integrated rotary grouting pile drilling rig for positioning and driving includes a mounting frame 1, a connecting arm 2, a grouting mechanism 3, and a positioning block 4.

[0036] Tracked wheels 5 are mounted on both sides of the mounting frame 1. These tracks 5 drive the device's movement and can be controlled by a controller. An electrical box 6 is mounted on the upper end of the mounting frame 1 for power supply. The upper end of the mounting frame 1 also has a mounting groove containing two screw drive mechanisms. Figure 2 and Figure 3 As shown, lead screw drive mechanism one and lead screw drive mechanism two specifically include a mounting frame 7, and a lead screw 8 is respectively installed inside the mounting frame 7. One end of the lead screw 8 is connected to the inner wall of the mounting frame 7 through a bearing, and the other end of the lead screw 8 passes through the mounting frame 7 and is connected to the drive component. Figure 4As shown, the driving component specifically includes a third motor 9 and a bevel gear transmission assembly 10 fixed to the output shaft of the third motor 9. The bevel gear transmission assembly 10 is fixed to one end of a lead screw 8. Two lead screws 8 pass through slider 11 and slider 2 12 respectively and are threadedly connected to slider 11 and slider 2 12 respectively. The two ends of slider 11 and slider 2 12 are in contact with the inner wall of the mounting frame 7, thereby playing a limiting role. The third motor 9 and the bevel gear transmission assembly 10 drive the lead screws 8 to rotate, thereby driving slider 11 and slider 2 12 to move within the mounting frame 7. The second lead screw transmission mechanism is fixed to the upper end of slider 11, and the moving directions of slider 11 and slider 2 12 are perpendicular to each other. A movable plate 13 is fixed to the upper end of slider 2 12. The first lead screw transmission mechanism can drive the movable plate 13 to move laterally in the horizontal plane, and the second lead screw transmission mechanism can drive the movable plate 13 to move vertically in the horizontal plane.

[0037] like Figure 1 As shown, a hinge 14 is fixed to the lower end of the connecting arm 2. The hinge 14 is rotatably connected to the hinge shaft 15, specifically through a bearing connection. A triangular limiting block 16 is fixed to the hinge shaft 15, and the bottom of the triangular limiting block 16 is fixed to the upper end of the moving plate 13. By setting the triangular limiting block 16, the connecting arm 2 can only rotate clockwise as shown in the figure. The connecting arm 2 is equipped with a lifting mechanism, which includes a conveyor belt 17, specifically a conveyor track. The connecting arm 2 has an installation cavity, and the conveyor belt 17 is installed in the installation cavity. Sliding holes 18 are respectively provided on the side walls of the connecting arm 2, and the sliding holes 18 communicate with the installation cavity. Sliding blocks 4 are fixed to both sides of the conveyor belt 17, and the sliding blocks 4 pass through the sliding holes 18 and are fixed to the lifting block 19. During the rotation of the conveyor belt 17, the sliding blocks 4 move vertically, thereby driving the lifting block 19 to move vertically. A positioning device 20 is fixed on the lifting block 19, and the positioning device 20 is connected to a total station. The grouting mechanism 3 is fixed on the lifting block 19. The grouting mechanism 3 has an inlet and an outlet, and adopts an existing high-pressure grouting mechanism. The outlet of the grouting mechanism 3 is connected to the hollow drill rod 21, and the hollow drill rod 21 is rotatably connected to the outlet of the grouting mechanism 3, specifically through a bearing connection. Figure 2 As shown, a drill bit 22 is fixed to the lower end of the hollow drill rod 21. The drill bit 22 is a slurry-producing drill bit 22. The hollow drill rod 21 and the drill bit 22 are driven by existing technology, or a drive motor is directly installed on the lifting block 19 to drive the hollow drill rod 21 to rotate through gear transmission.

[0038] like Figure 5As shown, the positioning block 4 has a through hole 23 for the hollow drill rod 21 to pass through. The positioning block 4 is movably mounted on a fixed frame. The fixed frame consists of two parallel horizontal bars 24 and two parallel vertical bars 25. The horizontal bars 24 are fixed to the two vertical bars 25 respectively, and the horizontal bars 24 and vertical bars 25 are perpendicular to each other. The lower ends of both the horizontal bars 24 and vertical bars 25 are fixed with ground inserts 26 for fixing to the ground. The upper ends of both the horizontal bars 24 and vertical bars 25 are provided with sliding grooves 27. Sliding blocks 28 are respectively fitted on the outside of the horizontal bars 24 and vertical bars 25, and the sliding blocks 28 move along the sliding grooves 27. Four connecting rods 29 are fixed to the outer wall of the positioning block 4. The ends of the connecting rods 29 away from the positioning block 4 pass through the sliding blocks 28, and the sliding blocks 28 have through holes through which the connecting rods 29 pass. The positioning block 4 can be moved within the fixed frame by using the sliding blocks 28.

[0039] The slider 328 moves the positioning block 4 in the following way: Figure 6 As shown, the slider 3 28 has a mounting cavity 2 30, which houses a motor 31. The output shaft of the motor 31 is fixed to a gear 32. Two rotating shafts 33 are also arranged parallel to each other within the mounting cavity 30. The two ends of each rotating shaft 33 are connected to the inner wall of the mounting cavity 30 via bearings. An auxiliary rotating wheel 34 is fixed to each rotating shaft 33. A connecting rod 29 is located between the two auxiliary rotating wheels 34, with its upper and lower ends in contact with the auxiliary rotating wheels 34. Gears 2 35 and 36 are fixed to each rotating shaft 33, meshing with gears 1 32 and 36 respectively. The motor 31 drives gear 1 32 to rotate, which in turn drives gears 2 35 and 36 to rotate in opposite directions. These gears, in turn, drive the two rotating shafts 33 and the auxiliary rotating wheels 34 to rotate in opposite directions. This allows the connecting rod 29 to move using the two auxiliary rotating wheels 34, thus moving the positioning block 4.

[0040] The slider 3 28 moves along the slide groove 3 27 in the following manner, as follows: Figure 6 As shown, slider 28 has a mounting cavity 37, which houses motor 38. The output shaft of motor 38 is fixed to a driving bevel gear 39, which meshes with a driven bevel gear 40. Two pulleys 41 are also installed within mounting cavity 37, within slide groove 27. Both pulleys 41 are fixed to a connecting shaft 42, whose ends are connected to the inner wall of mounting cavity 37 via bearings. The driven bevel gear 40 is fixed to the connecting shaft 42 containing one of the pulleys 41. Motor 38 drives the driving bevel gear 39 to rotate, which in turn drives the driven bevel gear 40 to rotate. The driven bevel gear 40 then drives the pulley 41 to rotate along slide groove 27, thus moving slider 28 along slide groove 27.

[0041] The fixed frame and the movable plate 13 are detachably connected, and the connection method is as follows: Figure 6 As shown, a connecting plate 43 is fixed on the mounting bracket, such as... Figure 7 As shown, a connecting plate 44 is fixed on the movable plate 13, as... Figure 8 As shown, connecting plate 1 43 and connecting plate 2 44 are engaged. Specifically, connecting plate 2 44 has a groove 45 for engaging connecting plate 1 43, and the upper and lower ends of the groove 45 are respectively provided with slots 46. The upper and lower ends of connecting plate 1 43 are respectively provided with movable blocks 47, which are adapted to the slots 46. Figure 9 As shown, the connecting plate 43 has placement slots 48 at its upper and lower ends for placing the locking block 47. A spring 49 is installed inside each slot 48, with one end fixed to the bottom of the slot and the other end fixed to the locking block 47. A rotating rod 50 is installed inside the connecting plate 43, with one end extending out of the connecting plate 43 and fixed to the handle 51, and the other end connected to the connecting plate 43 via a bearing. Track rollers 52 are fixed to the rotating rod 50, with both ends fixed to one end of the track 53, and the other ends of the track 53 passing through the placement slots 48 and fixed to the locking block 47. Two sets of sliding grooves 54 are provided on the side wall of the connecting plate 43. Since the locking block 47 is relatively long, multiple sliding grooves 54 can be provided in each set. A pull rod 55 is installed inside each sliding groove 54, with one end extending out of the sliding groove 54 and fixed to the handle 57. The other end of the pull rod 55 is fixed to the insert block 56. The vertical cross-section of the insert block 56 is a right-angled triangle, and the end of the insert block 56 near the locking block 47 is the hypotenuse of the right-angled triangle. A second spring 58 is fitted outside the pull rod 55 and inside the slide groove 44. One end of the second spring 58 is fixed to the inner wall of the slide groove 44, and the other end of the second spring 58 is fixed to the insert block 56. The locking block 47 has a slot 59 that matches the insert block 56 at the end near the insert block 56. A stop block 60 is also fixed on the pull rod 55. The stop block 60 is located outside the connecting plate 43 and can limit the distance the pull rod 55 can move.

[0042] When it is necessary to disassemble the fixed frame and the movable plate 13, turn the handle 51. The handle 51 drives the track wheel 5 to rotate, and the track wheel 5 drives the track inward. The track drives the locking block 47 from the locking slot 46 into the placement slot 48, and the spring 49 retracts. During the process of the locking block 47 moving into the placement slot 48, it presses against the insert block 56, the pull rod 55 moves outward, and the spring 58 retracts. When the locking block 47 is fully inserted into the placement slot 48, the slot 59 on the locking block 47 moves to a position flush with the insert block 56. At this time, the spring 58 rebounds, causing the insert block 56 to insert into the slot 59, thus limiting the locking block 47. Then, simply pull the connecting plate 43 out of the groove 45 of the connecting plate 44.

[0043] When it is necessary to connect the fixed frame and the movable plate 13, insert the connecting plate 1 43 into the groove 45 of the connecting plate 2 44, pull the handle 2 57 outward, the handle 2 57 drives the pull rod 55 to move outward, and the insert 56 leaves the slot 59. Since there is no limiting effect of the insert 56, under the action of the spring 1 49, the locking block 47 moves out of the placement groove 48 and extends into the locking groove 46, thereby fixing the connecting plate 1 43 and the connecting plate 2 44.

[0044] Working principle: When determining the pile position for rotary jet grouting, the pile position is first roughly determined using the positioning instrument 20 and tracked wheels 5, based on the coordinates provided by the total station. After the pile position is roughly determined, the fixing frame and moving plate 13 are disassembled. The fixing frame is lowered and fixed to the ground using the ground plug 26. Then, the moving plate 13 is moved by the first and second screw drive mechanisms, while the positioning block 4 is moved by the first motor 31 and the second motor 38, thereby adjusting the position of the drill bit 22 and ensuring that the hollow drill rod 21 is always within the positioning block 4, achieving precise locking of the pile position. Then, the grout enters the hollow drill rod 21 from the grouting mechanism 3 and is sprayed out from the drill bit 22, forming a highly concentrated liquid flow that directly damages the soil. During the spraying process, the conveyor belt 17 drives the hollow drill rod 21 and the drill bit 22 to move vertically and rotate, so that the grout and the soil are fully mixed and formed into a columnar solidified body of a certain diameter in the soil, thereby strengthening the foundation.

[0045] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the present invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
