Description

Technical Field

[0001] The invention relates to the technical field of concrete bored pile production, in particular to concrete bored pile casting equipment. Background Art

[0002] Concrete bored piles are a commonly used pile foundation construction method in foundation engineering. Pile bodies are formed by pouring concrete into underground boreholes to increase the bearing capacity and stability of the foundation. In the production process of concrete bored piles, pouring equipment is a crucial tool used to transport concrete from the mixing plant to the borehole.

[0003] The concrete poured into the borehole often contains air that has not been discharged, which causes more bubbles to form inside the concrete, resulting in a low density of the bored concrete pile, which can easily cause quality problems of the bored concrete pile. For this reason, it is necessary to compact the concrete in the borehole, but general bored concrete pile casting equipment is limited by its structure and can only enter the borehole without a steel cage installed to carry out concrete pouring and compacting operations. If a steel cage is installed in the borehole, the steel cage will hinder the concrete pile casting equipment from entering the borehole, making it impossible for general equipment to carry out concrete pouring and compacting operations on the borehole with the steel cage installed.

[0033] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0034] Example 1, see Figures 1 to 14As shown, a concrete pile casting device includes a frame 1, the frame 1 is connected to a control box 2, and further includes:

[0035] An inflatable wire-paying structure 3 connected to the frame 1, the inflatable wire-paying structure 3 includes an outer ring hanging mechanism 4 connected to the frame 1, and the frame 1 is connected to an air supply hanging mechanism 5;

[0036] A counterweight static pressure structure 6 connected to the outer ring vertical release mechanism 4, the counterweight static pressure structure 6 is used to perform static pressure operation on the concrete layer between the drill hole and the steel cage;

[0037] The inflatable side pressure structure 7 is connected to the air supply vertical release mechanism 5, and the inflatable side pressure structure 7 includes a center frame 8 connected to the air supply vertical release mechanism 5, the center frame 8 is connected to the steel cage abutment part 9, the steel cage abutment part 9 is connected to the concrete diverter head 10, the concrete diverter head 10 is connected to the concrete feeding pipe 11, the center frame 8 is connected to the inflatable expansion part 12, the inflatable expansion part 12 is connected to the air supply vertical release mechanism 5, and a vibrating rod 13 is fixedly installed at the bottom of the inflatable expansion part 12.

[0038] When in use, the steel cage is sunk into the borehole, the concrete feeding pipe 11 is connected to the external concrete pump, so that the external concrete pump continuously delivers concrete to the concrete feeding pipe 11, the air supply hanging mechanism 5 hangs the center frame 8 down to the bottom of the borehole, and the center frame 8 is surrounded by the steel cage, the steel cage abutment part 9 abuts the inner wall of the steel cage, and the outer ring hanging mechanism 4 releases the counterweight static pressure structure 6 into the annular gap between the borehole and the steel cage, as the concrete passes through the concrete feeding pipe 11 into the concrete diversion head 10, so that the concrete is sprayed. The concrete enters the steel cage, and the concrete passes through the steel cage, so that the concrete enters between the steel cage and the borehole, and then the counterweight static pressure structure 6 performs static pressure operation on the concrete, and as the air supply vertical release mechanism 5 inflates the inflation part 12, the volume of the inflation part 12 expands, so that the inflation part 12 squeezes the concrete to compact the concrete layer, and as the air supply vertical release mechanism 5 lifts the inflation side pressure structure 7, the concrete continues to fill into the steel cage, and the vibrator 13 vibrates the filled concrete to compact the concrete. The present invention cooperates with the inflation line structure 3, the counterweight static pressure structure 6, and the inflation side pressure structure 7 to facilitate the filling of concrete layer by layer in the borehole with the steel cage installed and compact the concrete by center extrusion, end static pressure and vibration. While improving the effect of compacting concrete, the present invention makes it suitable for the operation of pouring concrete into the borehole with the steel cage installed.

[0039] In one aspect of this embodiment, the outer ring hanging mechanism 4 includes multiple chassis 14 fixedly connected to the frame 1. The chassis 14 is fixedly connected to a first motor 15. The output end of the first motor 15 is fixedly connected to a first pulley 16. A pull rope 17 is wound around the first pulley 16. The pull rope 17 is wound around a first driven pulley 18. The first driven pulley 18 is rotatably mounted within the chassis 14. The pull rope 17 is fixedly connected to a clamping joint 19. A first electromagnet 20 is fixedly mounted within the clamping joint 19. The first electromagnet 20 is connected to a ferromagnetic latch 21 via a spring. The latch 21 is slidably connected to the inner wall of the clamping joint 19. The latch 21 and the clamping joint 19 are both movably connected to the counterweight static pressure structure 6. The first motor 15 drives the first pulley 16 to rotate, and the rotating first pulley 16 drives the pull rope 17. As the pull rope 17 is released, the clamping joint 19 and the latch 21 are lowered, causing the counterweight static pressure structure 6 to descend, thereby adjusting the height of the counterweight static pressure structure 6.

[0040] In one case of this embodiment, the counterweight static pressure structure 6 includes a pressure plate 22, and the pressure plate 22 has multiple groups of screws 23 fixedly installed on the side facing the clamping joint 19. The multiple groups of screws 23 are commonly connected to multiple groups of stacked counterweight plates 24. The group of counterweight plates 24 arranged at the bottom layer abuts against the pressure plate 22, and the group of counterweight plates 24 arranged at the top layer abuts against a nut 25 threadedly connected to the screw 23. The screw 23 is fixedly connected to a plug joint 26 movably connected to the clamping joint 19, and the plug joint 26 is movably connected to the pin 21. When the pin 21 is engaged with the plug connector 26, the plug connector 26 is connected to the clamping connector 19. Since the screw 23 connects the pressure plate 22 and the plug connector 26, as the pull rope 17 pulls the clamping connector 19, the plug connector 26 is lifted, thereby raising the height of the pressure plate 22. The pressure plate 22 is used to apply static pressure to the concrete, and the counterweight plate 24 is mounted on the screw 23 to increase the maximum static pressure of the pressure plate 22 on the concrete. The nut 25 is used to suspend the pressure plate 22 for movement.

[0041] In one case of this embodiment, the air supply vertical release mechanism 5 includes a central box 27 fixedly connected to the frame 1, and a second motor 28 is fixedly installed in the central box 27, and the output end of the second motor 28 is fixedly connected to a pipe release wheel 29, and a protective tube 30 is wrapped around the pipe release wheel 29, and the protective tube 30 is fixedly connected to the central frame 8. A first air hose 31 and a second air hose 32 are installed in the protective tube 30, and the first air hose 31 and the second air hose 32 are both connected to the inflation part 12, and the first air hose 31 is fixedly connected to the first air supply part 33, and the second air hose 32 is fixedly connected to the second air supply part 34, and the first air supply part 33 and the second air supply part 34 are both fixedly connected to the central box 27. The second motor 28 drives the tube-releasing wheel 29 to rotate to control the release and reeling of the protective tube 30, thereby controlling the height of the center frame 8. The first air supply part 33 and the second air supply part 34 are respectively used to inflate and exhaust the first air guide hose 31 and the second air guide hose 32 to inflate or exhaust the inflatable expansion part 12, thereby controlling the position of the inflatable expansion part 12.

[0042] In one aspect of this embodiment, the first air supply unit 33 and the second air supply unit 34 each include two sets of protective covers 35 fixedly connected to the central box 27. An air pump 36 is fixedly installed within the protective covers 35, and an air extraction pump 37 is fixedly installed within the protective covers 35. The air pump 36 and the air extraction pump 37 are commonly connected to a three-way pipe fitting 38, and the three-way pipe fitting 38 is connected to an air pressure detector 39. The three-way pipe fitting 38 of the first air supply unit 33 is fixedly connected to the first air guide hose 31, and the three-way pipe fitting 38 of the second air supply unit 34 is fixedly connected to the second air guide hose 32. The air pump 36 and the air extraction pump 37 are used to perform inflation and extraction operations, respectively. During these operations, air flows through the three-way pipe fitting 38, and the air pressure detector 39 performs air pressure detection. Both the first air guide hose 31 and the second air guide hose 32 serve as air guides.

[0043] In one case of this embodiment, the steel cage abutment portion 9 includes multiple groups of rectangular sleeves 40 fixedly connected to the center frame 8, and the multiple groups of rectangular sleeves 40 are fixedly connected to the concrete diverter 10. A second electromagnet 41 is fixedly installed in the rectangular sleeve 40, and the second electromagnet 41 is fixedly connected to a buffer spring, and the buffer spring is fixedly connected to a permanent magnet 42, and the permanent magnet 42 is fixedly connected to a rectangular bar 43, and the rectangular bar 43 is slidingly connected to the rectangular sleeve 40. A tilting plate 45 is fixedly installed at one end of the rectangular bar 43 away from the rectangular sleeve 40, and the rectangular bar 43 is fixedly connected to a double-output shaft motor 46, and the output end of the double-output shaft motor 46 is fixedly connected to a screw rod 47, and the screw rod 47 is threadedly connected to a friction block 48 slidingly connected to the rectangular bar 43, and the friction block 48 abuts against a friction bar 49 fixedly installed in the rectangular sleeve 40. The magnetic field emitted by the second electromagnet 41 acts on the permanent magnet 42, so that the permanent magnet 42 and the second electromagnet 41 approach each other, and then the permanent magnet 42 drives the rectangular bar 43 to move, so that the tilting plates 45 approach each other, so that the tilting plates 45 are away from the steel cage, thereby facilitating the movement of the center frame 8 in the steel cage. As the second electromagnet 41 and the permanent magnet 42 generate repulsive force against each other, under the push of the permanent magnet 42, the rectangular bar 43 drives the tilting plate 45 to abut against the steel cage wall, and the double-output shaft motor 46 drives the screw rod 47 to rotate, and the screw rod 47 drives the friction block 48 to abut against the friction bar 49 to limit the movement of the rectangular bar 43, thereby avoiding the shaking of the steel cage abutment part 9, and thus stabilizing the inflatable expansion part 12.

[0044] Example 2, based on Example 1, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14The inflatable expansion portion 12 includes a ventilation frame 50 fixedly connected to the center frame 8. The interior of the ventilation frame 50 is a hollow structure. The vibrating rod 13 is fixedly connected to the bottom end surface of the ventilation frame 50. The ventilation frame 50 is fixedly connected to the first air guide hose 31. The ventilation frame 50 is slidably connected to multiple groups of side pressure frames 52. Multiple groups of side pressure frames 52 are commonly fixedly connected to an air bag 53. The air bag 53 is fixedly connected to the ventilation frame 50. The side pressure frames 52 are hinged with an elastic hinge frame 54. Multiple groups of the elastic hinge frames 54 are commonly hinged with a group of top support frames 55. The elastic hinge frame 54 includes The protective sleeve 58 is slidably connected to two groups of hinged plates 59, and a return spring is installed between the two groups of hinged plates 59. The two groups of hinged plates 59 are hinged to the top support frame 55 and the side pressure frame 52 respectively. The top support frame 55 is fixedly connected to the upper inner wall of the airbag 53, and the top support frame 55 is slidably connected to the ventilation frame 50. The ventilation frame 50 is fixedly connected to the inflation head 56 extending into the airbag 53. The inflation head 56 is fixedly connected to a conduit 57, which is fixedly connected to the center frame 8, and the conduit 57 is fixedly connected to the second air guide hose 32. The second air guide hose 32 introduces high-pressure gas into the conduit 57, so that the airbag 53 is expanded by the high-pressure gas to apply a squeezing force to the concrete. During this period, the first air guide hose 31 fills gas into the ventilation frame 50, so that the high-pressure gas pushes the side pressure frame 52, so that the side pressure frame 52 applies a supporting force from the inside of the airbag 53 to ensure the shape and structure of the airbag 53 when the airbag 53 applies lateral pressure to the concrete. As the concrete applies pressure from above the airbag 53, the top support frame 55 is compressed. At this time, the elastic hinge frame 54 applies a thrust to the side pressure frame 52, and uses the reaction force of the concrete on the side pressure frame 52 to limit the downward movement of the top support frame 55, thereby preventing the airbag 53 from being crushed.
