Description

Technical Field

[0001] The present invention relates to the technical field of pile driving and soil extraction, and specifically to a building pile driving and soil extraction device. Background Art

[0002] The purpose of building pile driving is to increase the bearing capacity and stability of the foundation to ensure the safety of the building during use. Pile driving and soil extraction means that during pile driving, since the pile body needs to be embedded in the ground, it is necessary to remove the residual floating soil in the drilled pile hole so that the pile body can be smoothly embedded in the pile hole.

[0003] For the traditional method of clearing soil in the pile hole, people often shovel the soil into a bucket, and then a hoisting device hoists the bucket filled with soil and stones out of the pile hole. However, the inner wall of the pile hole sometimes loosens, causing the soil to fall off, and sometimes groundwater suddenly seeps out, which cannot guarantee the safety of personnel. Summary of the Invention

[0004] The purpose of the present invention is to provide a building pile driving and soil extraction device to solve the problems raised in the above background art.

[0013] As a further improvement of the present invention: The centering moving component includes a sector plate fixedly connected to the central frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] During use, the frame is installed on an engineering vehicle, so that the engineering vehicle drives the frame to move towards the pile hole. The first active telescopic rod drives the bracket to move, so that the bracket drives the track frame to rotate. The track frame drives the rotating frame to rotate. The lifting and placing mechanism releases the rotating driving mechanism into the pile hole, so that the rotating driving mechanism drives the soil-scraping and collecting mechanism to fall into the pile hole. As the rotating driving mechanism drives the hanging frame to sink to the bottom of the pile hole, the synchronous closing part falls to the bottom of the pile hole. The rotating driving mechanism drives the hanging frame to rotate. The hanging frame drives the first multi-prism to rotate. The first multi-prism drives the central frame to rotate. The central frame drives the centering moving component to rotate, so that the three sets of soil-shoveling components rotate. During this period, driven by the centering moving component, the soil-shoveling components push the floating soil at the bottom of the pile hole to the center of the pile hole and clean out an annular space at the bottom of the pile hole, so as to provide space for placing the semi-annular soil-collecting mechanism. Then the lifting and placing mechanism lifts the rotating driving mechanism, so as to lift the hanging frame out of the pile hole. At this time, the two sets of soil-shoveling components are disassembled, and the other set of soil-shoveling components is disassembled from the centering moving component and reversed 180 degrees. Then the reversed soil-shoveling component is installed on the centering moving component. At this time, as the soil-scraping and collecting mechanism falls back to the bottom of the pile hole again, the soil-shoveling component inserts into the center of the pile hole to pile up the floating soil. The centering moving component drives the soil-shoveling component to move towards the semi-annular soil-collecting mechanism that has fallen to the bottom of the pile hole, so as to push the floating soil into the semi-annular soil-collecting mechanism, thereby collecting the floating soil at the bottom of the pile hole. The present invention replaces personnel to collect the floating soil at the bottom of the pile hole through the cooperation of the lifting and placing mechanism, the rotating driving mechanism, and the soil-scraping and collecting mechanism, avoiding manual soil-shoveling operations by personnel entering the pile hole and protecting the safety of personnel.

Specific embodiments

[0029] The technical solution of the present invention will be further described in detail below in conjunction with specific embodiments.

[0030] Embodiment 1, referring to Figures 1 to 10 As shown, a soil extraction device for building pile driving includes a frame 1. The frame 1 is fixedly connected with a controller. Under normal circumstances, the frame 1 needs to be installed in the bucket of an engineering vehicle. The frame 1 is hinged with a first active telescopic rod 2. The moving end of the first active telescopic rod 2 is hinged with a bracket 3. The bracket 3 is fixedly connected with a track frame 4. The lower end of the track frame 4 is fixedly installed with a rotating frame 5 hinged with the frame 1. It further includes:

[0031] A hoisting and placing mechanism 6 connected to the rotating frame 5, and the hoisting and placing mechanism 6 is connected to the track frame 4;

[0032] A rotation driving mechanism 7 connected to the hoisting and placing mechanism 6, and the rotation driving mechanism 7 is connected to the rotating frame 5;

[0033] A soil scraping and collecting mechanism 8 connected to the rotation driving mechanism 7. The soil scraping and collecting mechanism 8 includes a hanging frame 9 installed at the bottom of the rotation driving mechanism 7. The rotation driving mechanism 7 is connected to the hanging frame 9 through multiple groups of nuts. The hanging frame 9 is connected with a semi-circular soil collecting mechanism 10. The hanging frame 9 is connected with a synchronous closing part 11. The synchronous closing part 11 includes a first multi-prism 12 fixedly connected with the hanging frame 9. The lower end of the first multi-prism 12 is fixedly installed with a central frame 13. The central frame 13 is fixedly connected with a camera 14. The lower end of the central frame 13 is fixedly installed with a centering moving component 15. The centering moving component 15 is connected with the hanging frame 9. The centering moving component 15 is movably connected with three soil shoveling components 16. By applying a driving force to the soil shoveling components 16, the moving directions of the three soil shoveling components 16 extend to the same position. The soil shoveling components 16 are used for pushing the floating soil at the bottom of the pile hole.

[0034] During use, the rack 1 is installed on an engineering vehicle, enabling the engineering vehicle to drive the rack 1 to move towards the pile hole. The first active telescopic rod 2 drives the support 3 to move, causing the support 3 to drive the track frame 4 to rotate. The track frame 4 drives the rotating frame 5 to rotate. The hoisting mechanism 6 allows the rotating drive mechanism 7 to fall into the pile hole by releasing the rotating drive mechanism 7, causing the rotating drive mechanism 7 to drive the soil scraping and collecting mechanism 8 to fall into the pile hole. As the rotating drive mechanism 7 drives the hanging frame 9 to sink to the bottom of the pile hole, the synchronous closing part 11 also falls to the bottom of the pile hole. The rotating drive mechanism 7 drives the hanging frame 9 to rotate, the hanging frame 9 drives the first multi-prism 12 to rotate, the first multi-prism 12 drives the central frame 13 to rotate, and the central frame 13 drives the centering movement component 15 to rotate, so that the three soil scraping components 16 rotate. During this period, driven by the centering movement component 15, the soil scraping components 16 push the floating soil at the bottom of the pile hole to the center of the pile hole and clean out an annular space at the bottom of the pile hole, in order to provide space for the placement of the semi-circular soil collecting mechanism 10. Then, the hoisting mechanism 6 hoists the rotating drive mechanism 7 to lift the hanging frame 9 out of the pile hole. At this time, the two soil scraping components 16 are disassembled, and the other soil scraping component 16 is disassembled from the centering movement component 15 and reversed by 180 degrees. Then, the reversed soil scraping component 16 is installed on the centering movement component 15. At this time, as the soil scraping and collecting mechanism 8 falls back to the bottom of the pile hole again, the soil scraping component 16 is inserted into the center of the pile hole to accumulate the floating soil. The centering movement component 15 drives the soil scraping component 16 to move towards the semi-circular soil collecting mechanism 10 that has fallen to the bottom of the pile hole, so as to push the floating soil into the semi-circular soil collecting mechanism 10, thereby collecting the floating soil at the bottom of the pile hole. Through the cooperation of the hoisting mechanism 6, the rotating drive mechanism 7, and the soil scraping and collecting mechanism 8, the present invention replaces personnel to collect the floating soil at the bottom of the pile hole, avoiding manual soil scraping operations by personnel entering the pile hole and protecting personnel safety.

[0035] In one case of this embodiment, the hoisting mechanism 6 includes a first motor 17 fixedly connected to the rotating frame 5. The output shaft of the first motor 17 is fixedly connected with a wire winding wheel 18. A steel cable 19 is wound around the wire winding wheel 18. The steel cable 19 is fixedly connected with a lifting frame 20 that is slidably connected to the track frame 4. A driven wheel 21 is rotatably connected to the track frame 4, and the driven wheel 21 is in contact with the steel cable 19. The lifting frame 20 is fixedly connected with a limit cover 22, and the limit cover 22 is connected to the rotating drive mechanism 7. The first motor 17 drives the wire winding wheel 18 to rotate. The wire winding wheel 18 drives the steel cable 19. As the steel cable 19 is wound, the steel cable 19 pulls the lifting frame 20 to rise. The lifting frame 20 slides along the track frame 4, and the lifting frame 20 drives the limit cover 22 to move. The limit cover 22 drives the rotating drive mechanism 7 to rise. During this period, the driven wheel 21 provides moving support for the steel cable 19.

[0036] In a case of this embodiment, the rotation driving mechanism 7 includes a gear cover 23 fixedly connected to the rotating frame 5. The gear cover 23 is fixedly connected with a second motor 24. The output shaft of the second motor 24 is fixedly connected with a first gear 25. The first gear 25 is meshed and connected with a second gear 26. The second gear 26 is slidably connected with a multi-edge frame 27. A through hole 28 adapted to the multi-edge frame 27 is formed on the gear cover 23. The multi-edge frame 27 is coaxially and fixedly connected with a ball head 29. The ball head 29 is rotatably connected with multiple groups of balls 30 in contact with the limit cover 22. The lower end of the multi-edge frame 27 is connected to the hanging frame 9. The multi-edge frame 27 is threadedly connected with multiple groups of nuts, and the nuts are abutted against the hanging frame 9. During the upward movement of the limit cover 22, the limit cover 22 causes the balls 30 to drive the ball head 29 to rise by lifting the balls 30. The ball head 29 drives the multi-edge frame 27 to rise. The multi-edge frame 27 drives the hanging frame 9 to rise. The multi-edge frame 27 and the second gear 26 slide relative to each other. And as the second motor 24 drives the first gear 25 to rotate, the first gear 25 drives the second gear 26 to rotate. The second gear 26 drives the multi-edge frame 27 to rotate. The multi-edge frame 27 drives the hanging frame 9 to rotate. The hanging frame 9 drives the semi-circular soil collecting mechanism 10 and the synchronous closing part 11 to rotate, so as to adjust the positions of the semi-circular soil collecting mechanism 10 and the synchronous closing part 11.

[0037] In a case of this embodiment, the semi-circular soil collecting mechanism 10 includes a second active telescopic rod 31 fixedly connected to the hanging frame 9. The moving end of the second active telescopic rod 31 is fixedly connected with a connecting frame 32. The connecting frame 32 is slidably connected with a first multi-prism 12. The connecting frame 32 is fixedly connected with a semi-circular soil-carrying frame 33. A soil-shoveling bevel 34 is arranged on the semi-circular soil-carrying frame 33. As the hanging frame 9 moves into the pile hole, the hanging frame 9 drives the second active telescopic rod 31 to move. The second active telescopic rod 31 drives the connecting frame 32 to move along the first multi-prism 12, so as to make the connecting frame 32 drive the semi-circular soil-carrying frame 33 to move, thereby adjusting the relative height between the semi-circular soil-carrying frame 33 and the soil-shoveling assembly 16.

[0038] In a case of this embodiment, the centric moving component 15 includes a sector plate 35 fixedly connected to the center frame 13. A central groove 36 is formed in the sector plate 35. Side shifting grooves 37 are formed in the sector plate 35 on both sides of the central groove 36. A relay groove 38 is provided between a set of side shifting grooves 37 and the central groove 36. The relay groove 38 is formed in the sector plate 35. A set of central grooves 36, two sets of side shifting grooves 37, and two sets of relay grooves 38 all extend towards the same point. The hanging frame 9 is fixedly connected with a third active telescopic rod 39. The moving end of the third active telescopic rod 39 is fixedly connected with a hinge frame 40 slidably connected to the first multi-prism 12. The hinge frame 40 is hinged with a first hinge plate 41. The first hinge plate 41 is hinged with a central slider 42 slidably connected to the central groove 36. The central slider 42 is hinged with two sets of second hinge plates 43. One set of second hinge plates 43 is hinged with a set of relay sliders 44. The relay sliders 44 are slidably connected to the relay grooves 38. The relay sliders 44 are hinged with side sliders 46 through third hinge plates 45. The side sliders 46 are slidably connected to the side shifting grooves 37. Two sets of side sliders 46 and the central slider 42 are all connected with telescopic limiting components 47. The telescopic limiting components 47 are connected with the soil shoveling component 16. The third active telescopic rod 39 drives the hinge frame 40 to move. The hinge frame 40 drives the central slider 42 to move along the central groove 36 through the first hinge plate 41. The central slider 42 drives the second hinge plates 43 to move. The second hinge plates 43 drive the relay sliders 44 to move along the relay grooves 38. The relay sliders 44 drive the side sliders 46 to move through the third hinge plates 45. The moving side sliders 46 and the moving central slider 42 both drive the soil shoveling component 16 to move through the telescopic limiting components 47, so as to push the floating soil in the pile hole with the soil shoveling component 16 inserted into the soil. And as the soil shoveling component 16 below the side slider 46 is disassembled, and the soil shoveling component 16 below the central slider 42 is disassembled and reversed by 180 degrees and then reinstalled, and then the centric moving component 15 drives the soil shoveling component 16 to move, so as to push the soil into the semi-circular soil loading frame 33.

[0039] In one case of this embodiment, each of the three sets of telescopic limit components 47 includes multiple connecting rods 48. The multiple connecting rods 48 are fixedly connected to a double-opening frame 49 together. There are two symmetrically arranged and interconnected openings on the double-opening frame 49. The double-opening frame 49 is fixedly connected to a cylindrical cover 50. An electromagnet 51 is fixedly installed inside the cylindrical cover 50. The electromagnet 51 is fixedly connected to a spring. The spring is fixedly connected to an extension rod 52 that is slidably connected to the cylindrical cover 50. The extension rod 52 has ferromagnetism. The extension rod 52 is movably connected to the soil-shoveling component 16. The soil-shoveling component 16 is movably connected to the double-opening frame 49. The multiple connecting rods 48 of one set of telescopic limit components 47 are fixedly connected to the central slider 42, and the multiple connecting rods 48 of the other two sets of telescopic limit components 47 are fixedly connected to the side sliders 46. As the electromagnet 51 magnetically attracts the extension rod 52, the extension rod 52 slides towards the cylindrical cover 50, so that the extension rod 52 is separated from the soil-shoveling component 16, facilitating the disassembly of the soil-shoveling component 16 from the double-opening frame 49.

[0040] Embodiment 2. On the basis of Embodiment 1, refer to Figure 5 , Figure 6 , Figure 7 , Figure 10 . The soil-shoveling component 16 includes an insertion frame 53 that is movably connected to the double-opening frame 49. The insertion frame 53 is movably connected to the extension rod 52. The insertion frame 53 is fixedly connected to a baffle 54. An elastic strip 55 is fixedly installed at the lower end of the baffle 54. After the extension rod 52 is inserted into the insertion frame 53, the relative positions of the double-opening frame 49 and the insertion frame 53 are fixed. The side slider 46 or the central slider 42 drives the double-opening frame 49 to move through the connecting rod 48, so as to drive the insertion frame 53 to move. The insertion frame 53 drives the baffle 54 to move. The baffle 54 is used for earth-pushing operations. The moving baffle 54 drives the elastic strip 55 to move. By providing the elastic strip 55, the baffle 54 moves towards the semi-circular soil-carrying frame 33. During this process, the elastic strip 55 is squeezed and deformed when moving on the semi-circular soil-carrying frame 33, so as to prevent the semi-circular soil-carrying frame 33 from hindering the movement of the baffle 54.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention.
