Description

Technical Field

[0001] The present invention relates to the technical field of pile foundation concrete pouring, and particularly relates to an auxiliary pouring device for building pile foundation construction. Background Technique

[0002] Pile foundations are particularly suitable for situations where the bearing capacity of the surface soil layer is insufficient or a large amount of load needs to be transmitted to a deep stable soil layer. It mainly consists of two parts: a foundation pile and a bearing platform. The foundation pile is a columnar structure that penetrates into the underground soil or rock, which can be precast or cast in place. The bearing platform is a platform structure that connects the pile tops and distributes the loads of the upper structure.

[0003] Currently, when workers form a foundation pile by pouring, first, a pile hole needs to be formed at a designated position according to the design requirements by means of drilling, digging, punching, rotary drilling, etc. Then, a steel reinforcement cage is installed in the pile hole, and an appropriate number of conduits are sequentially spliced. Then, the spliced conduits are placed into the pile hole, and concrete can be poured to the bottom of the pile hole through the conduits. As the concrete is poured, the conduits are gradually lifted, and the depth of the conduits buried is always maintained within a certain range to ensure the compactness of the concrete. Currently, a threaded joint is usually installed at the end of the conduit. When workers splice two conduits, usually two workers are required to respectively fix the two conduits, align the ends of the two conduits, and then tighten the threaded joint to connect the ends of the two conduits through the threaded joint. When multiple conduits need to be spliced, this splicing method is rather troublesome, and subsequently, the multiple conduits need to be sequentially removed by loosening the threaded joint, which is time-consuming and laborious and will affect the work efficiency. Summary of the Invention

[0004] In view of this, the present invention provides an auxiliary pouring device for building pile foundation construction, which can overcome the drawback that the existing conduits for concrete pouring are rather troublesome to splice and remove, and will affect the work efficiency.

[0005] The technical solution is: an auxiliary pouring device for building pile foundation construction, including a loading hopper and a conduit body, and further including a connecting mechanism and an unlocking mechanism. The lower end of the loading hopper and the end of the conduit body are connected through the connecting mechanism, and the ends of two conduit bodies are also connected through the connecting mechanism. The unlocking mechanism is used to release the connection of the connecting mechanism. The connecting mechanism consists of a sealing ring, insertion blocks, clamping blocks, and a return spring. The sealing ring is connected to the upper end of the conduit body. Annular grooves adapted to the sealing ring are respectively opened at the lower end of the conduit body and the lower end of the loading hopper. The insertion blocks are symmetrically connected to the top surface of the conduit body. Insertion holes adapted to the insertion blocks are symmetrically opened at the bottom surface of the conduit body and the bottom surface of the loading hopper. The clamping blocks are slidably connected in the insertion blocks, and the return spring connects the clamping blocks and the insertion blocks.

[0006] Further, the unlocking mechanism includes a telescopic rod, a sliding ring, a connecting spring, a vertical rod and a pressing wheel. The telescopic rods are symmetrically connected to the lower end of the conduit body and the lower end of the loading hopper respectively. The sliding ring is connected to the upper end of the telescopic rod. The connecting spring is wound around the outside of the telescopic rod, and both ends of the connecting spring are connected to the bottom surface of the sliding ring and the top surface of the conduit body respectively. The vertical rods are symmetrically connected to the bottom surface of the sliding ring. The pressing wheel is rotatably connected to the lower end of the vertical rod, and the pressing wheel is in contact and cooperation with the clamping block.

[0007] Further, it further includes a corrugated protective cover. The corrugated protective cover is connected to the bottom surface of the sliding ring, and the insertion block and the telescopic rod are both located inside the corrugated protective cover.

[0008] Further, it further includes a centering mechanism. The centering mechanism includes a mounting plate, a rotating plate, a reset torsion spring, a roller and a locking assembly. The mounting plates are symmetrically connected to the conduit body at the lowermost side. The rotating plate is rotatably connected to the side surface of the mounting plate. The reset torsion spring connects the mounting plate and the rotating plate. The roller is rotatably connected to the end of the rotating plate. The locking assembly is used to lock the rotating plate.

[0009] Further, the locking assembly includes a wedge-shaped block, a connecting plate, a locking plate and a tension spring. The wedge-shaped block is connected to the side surface of the rotating plate. The connecting plate is connected to the side surface of the mounting plate. The locking plate is slidably connected to the connecting plate, and the locking plate catches the wedge-shaped block. The tension spring connects the locking plate and the connecting plate.

[0010] Further, it further includes a fixing block, a lifting shell, a connecting frame and a ball. The fixing blocks are symmetrically connected to the side surfaces of the sliding rings on the second conduit body from bottom to top. The lifting shell is connected to the bottom surface of the fixing block. The connecting frame is connected to the top surface of the locking plate. The balls are symmetrically rotatably connected to the upper ends of the connecting frame.

[0011] Further, it further includes a fixing plate and a hook. The fixing plates are symmetrically connected to the loading hopper. The hooks are symmetrically connected to the top surface of the fixing plate.

[0012] Further, it further includes a swing rod, a wire pulley, a steel wire rope and a blocking disc. The swing rod is rotatably connected to the top surface of one of the fixing plates. The wire pulley is rotatably connected to the end of the swing rod. The steel wire rope passes around the wire pulley, and the blocking disc is connected to the end of the steel wire rope.

[0013] The beneficial effects are as follows: 1. Through the cooperation of the insertion block, the insertion hole and the clamping block, the present invention only needs to move the ends of the two conduit bodies towards each other to complete the docking work of the two conduit bodies. After the concrete pouring is completed, only need to push the sliding ring downwards to separate the two conduit bodies. In this way, the docking and removal work of the conduit bodies can be quickly completed, improving work efficiency.

[0014] 2. By rotating the rotating plate upward by 90 degrees to unfold it, the rollers can be brought into contact with the inner wall of the steel reinforcement cage in the pile hole. During the lowering and lifting of the catheter body, the rollers can roll along the inner wall of the steel reinforcement cage, keeping the catheter body always at the center of the pile hole and ensuring uniform concrete pouring.

[0015] 3. By using the blocking plate to pre-block the lower end of the lowermost catheter body first, and then pulling out the blocking plate after the catheter body is filled with concrete, the concrete in the catheter body can fall downward into the pile hole to form a continuous concrete flow, ensuring continuous concrete pouring and achieving better pouring effect.

Detailed implementation manner

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment: An auxiliary perfusion device for building pile foundations in construction, as Figures 1-7As shown in the figure, it includes a loading hopper 1 and a conduit body 2. The upper diameter of the loading hopper 1 is larger than its lower diameter, and the lower diameter of the loading hopper 1 is the same as the diameter of the conduit body 2, which is convenient for workers to pour concrete into the loading hopper 1. Then the concrete can flow down along the inner wall of the loading hopper 1 into the conduit body 2 and flow down along the inner wall of the conduit body 2 to be poured into the pile hole. It also includes a connecting mechanism and an unlocking mechanism. The lower end of the loading hopper 1 and the upper end of the conduit body 2 can be quickly connected through the connecting mechanism, and the ends of two conduit bodies 2 can also be quickly connected through the connecting mechanism. The unlocking mechanism is used to release the connection of the connecting mechanism, so as to quickly separate the loading hopper 1 from the conduit body 2, and can also quickly separate the two spliced conduit bodies 2. In this way, the splicing work and disassembly work of the conduit body 2 can be quickly completed, improving work efficiency. The connecting mechanism is composed of a sealing ring 3, insertion blocks 5, clamping blocks 7 and a return spring 8. The sealing ring 3 is embedded in the upper end of the conduit body 2. Annular grooves 4 adapted to the sealing ring 3 are opened at the lower end of the conduit body 2 and the lower end of the loading hopper 1. When the lower end of the loading hopper 1 is spliced with the upper end of the conduit body 2, or the ends of two conduit bodies 2 are spliced, the corresponding sealing ring 3 can be inserted into the corresponding annular groove 4 to ensure good sealing between the loading hopper 1 and the conduit body 2 and between two conduit bodies 2. Four insertion blocks 5 are connected to the top surface of the conduit body 2 at intervals. The four insertion blocks 5 are distributed in a rectangle. Four insertion holes 6 are opened at intervals on the bottom surface of the conduit body 2 and the bottom surface of the loading hopper 1. The insertion holes 6 correspond to the insertion blocks 5 one by one and are vertically aligned. Both sides of the upper end of the insertion block 5 are inclined surfaces, so that when the lower end of the loading hopper 1 is spliced with the upper end of the conduit body 2, or the ends of two conduit bodies 2 are spliced, the insertion block 5 can be smoothly inserted into the corresponding insertion hole 6. The clamping block 7 is slidably connected to the insertion block 5. The end surface of the clamping block 7 away from the insertion block 5 is an inclined surface, and the bottom surface of the clamping block 7 is a flat surface. The two ends of the return spring 8 are respectively connected to the clamping block 7 and the insertion block 5.

[0031] As Figures 5-7 shown, the unlocking mechanism includes a telescopic rod 9, a sliding ring 10, a connecting spring 11, a vertical rod 12 and a pressing wheel 13. Telescopic rods 9 are connected to the front and rear sides of the lower end of the conduit body 2 and the lower end of the loading hopper 1. A sliding ring 10 is connected between the upper ends of the two telescopic rods 9. The connecting spring 11 is wound around the outside of the telescopic rod 9. Vertical rods 12 are symmetrically connected to the front and rear sides of the bottom surface of the sliding ring 10 on the left and right. The vertical rods 12 correspond to the clamping blocks 7 one by one. The pressing wheel 13 is rotatably connected to the lower end of the vertical rod 12, and the pressing wheel 13 contacts the inclined surface of the clamping block 7. It also includes a corrugated protective cover 101. The corrugated protective cover 101 is connected to the bottom surface of the sliding ring 10. The bottom surface of the corrugated protective cover 101 is respectively connected to the lower end of the conduit body 2 and the lower end of the loading hopper 1. The insertion block 5, the clamping block 7 and the telescopic rod 9 are all located in the corrugated protective cover 101 to prevent concrete from affecting the sliding of the clamping block 7 and the telescopic of the telescopic rod 9.

[0032] AsFigures 8-10 As shown, it further includes a centering mechanism. The centering mechanism includes a mounting plate 14, a rotating plate 15, a reset torsion spring 16, a roller 17 and a locking assembly. Mounting plates 14 are connected to the front, rear, left and right sides of the lowermost conduit body 2. The rotating plate 15 is rotatably connected to the side of the mounting plate 14. The reset torsion spring 16 is wound around the rotating shaft of the rotating plate 15, and the two ends of the reset torsion spring 16 are respectively connected to the mounting plate 14 and the rotating plate 15. The roller 17 is rotatably connected to the lower end of the rotating plate 15. The locking assembly is used to lock the rotating plate 15. The locking assembly includes a wedge block 18, a connecting plate 19, a locking plate 20 and a tension spring 21. The wedge block 18 is connected to the side of the rotating plate 15. The connecting plate 19 is connected to the side of the mounting plate 14, and the connecting plate 19 is located above the rotating plate 15. The locking plate 20 is slidably connected to the lower part of the connecting plate 19. The lower left side of the locking plate 20 is a slope, and the upper right side of the rotating plate 15 is a slope. When the rotating plate 15 moves upward, it will contact the locking plate 20. Through the extrusion between the slopes of the two, the locking plate 20 can be pushed to move. The top surface of the locking plate 20 is a plane, and the wedge block 18 is integrally in an inverted L shape. When the upper end of the rotating plate 15 moves to the top surface of the locking plate 20, the wedge block 18 can hook on the top surface of the locking plate 20, and the locking plate 20 plays a limiting role to prevent the wedge block 18 from moving downward to reset. The two ends of the tension spring 21 are respectively connected to the locking plate 20 and the connecting plate 19. It further includes a fixed block 22, a lifting shell 23, a connecting frame 24 and a ball 25. Four fixed blocks 22 are connected at intervals on the outside of the sliding ring 10 on the second conduit body 2 from bottom to top. A lifting shell 23 is connected between the bottom surfaces of the four fixed blocks 22. The lower end of the lifting shell 23 is a conical slope. The connecting frame 24 is connected to the top surface of the locking plate 20. Two balls 25 are symmetrically and rotatably connected to the upper end of the connecting frame 24. When the lifting shell 23 moves downward, its conical slope will contact the balls 25, so that the balls 25 can roll on the conical slope at the lower end of the lifting shell 23 to squeeze the balls 25 and the connecting frame 24 to move horizontally.

[0033] As Figure 11 and Figure 12 As shown, it further includes a fixing plate 26 and a hook 27. Fixing plates 26 are connected to the front, rear, left and right sides of the upper end of the loading hopper 1. Two hooks 27 are symmetrically connected to the top surfaces of the fixing plates 26. The hooks 27 are used to connect with the hook of the crane, which is convenient for the crane to lift the loading hopper 1. It further includes a swing rod 28, a wire pulley 29, a steel wire rope 30 and a plugging disc 31. The swing rod 28 is rotatably connected to the top surface of the right fixing plate 26. The bottom surface of the swing rod 28 is a plane, and the bottom surface of the swing rod 28 contacts the top surface of the right fixing plate 26, so that the swing rod 28 is in an inclined state, and the left end of the swing rod 28 is located on the axis of the conduit body 2. The wire pulley 29 is rotatably connected to the left end of the swing rod 28. The steel wire rope 30 passes around the wire pulley 29, and the plugging disc 31 is connected to the lower end of the steel wire rope 30.

[0034] ​After the steel reinforcement cage is installed in the pile hole, the worker can select an appropriate number of catheter bodies 2 according to the depth of the pile hole and connect the ends of the catheter bodies 2 in sequence. During the connection process of the catheter bodies 2, only need to align the ends of the two catheter bodies 2 and move them towards the side close to each other, then the insertion block 5 of the lower catheter body 2 can be inserted into the insertion hole 6 of the upper catheter body 2. When the locking block 7 in the insertion block 5 contacts the inner wall of the insertion hole 6, the inner wall of the insertion hole 6 will squeeze the locking block 7 to move towards the direction close to the insertion block 5, and the return spring 8 is compressed. When the locking block 7 in the insertion block 5 completely passes through the insertion hole 6, the locking block 7 in the insertion block 5 will separate from the inner wall of the insertion hole 6. At this time, the return spring 8 returns to its original state and can drive the locking block 7 to move and reset in the direction away from the insertion block 5. At this time, the bottom surface of the locking block 7 can buckle the lower end of the upper catheter body 2 to complete the connection work of the two catheter bodies 2; when it is necessary to put the lowermost catheter body 2 into the pile hole, the rotating plate 15 on the lowermost catheter body 2 can be rotated upwards by ninety degrees to unfold, and the return torsion spring 16 deforms. The rotating plate 15 can drive the roller 17 and the wedge block 18 to rotate upwards. When the wedge block 18 contacts the locking plate 20, it can squeeze the locking plate 20 to move in the direction away from the center of the catheter body 2, and the tension spring 21 is stretched. When the wedge block 18 disengages from the locking plate 20, the tension spring 21 will return to its original state and drive the locking plate 20 to move and reset in the direction close to the center of the catheter body 2 to make the locking plate 20 lock the wedge block 18; then the lowermost catheter body 2 can be put into the pile hole. At this time, the rollers 17 on the lowermost catheter body 2 will all contact the inner wall of the steel reinforcement cage, so that the lowermost catheter body 2 can be located at the center of the steel reinforcement cage. As the lowermost catheter body 2 is lowered, the rollers 17 can roll down along the inner wall of the steel reinforcement cage, so that the lowermost catheter body 2 always remains at the center of the steel reinforcement cage. Then, after each catheter body 2 is spliced, the spliced catheter body 2 is lowered by a certain depth. Until all the catheter bodies 2 are spliced, the hook 27 can be used in cooperation with the hook of the crane to lift the loading hopper 1 above the spliced catheter bodies 2. Similarly, the lower end of the loading hopper 1 can be spliced with the upper end of the uppermost catheter body 2, and the fixing plate 26 on the loading hopper 1 can be placed on the ground around the upper end of the pile hole;Then, wind the steel wire rope 30 around the guide pulley 29 and lower the plugging disc 31 into the pile hole. Under the action of the guide pulley 29, the plugging disc 31 can move downward along the axis of the conduit body 2. Eventually, the plugging disc 31 can block the lower end of the lowermost conduit body 2. Then, concrete can be poured into the loading hopper 1. The concrete in the loading hopper 1 will flow into the spliced conduit body 2. Since the plugging disc 31 blocks the lower end of the lowermost conduit body 2, the concrete in the conduit body 2 will not fall into the pile hole until the loading hopper 1 and the conduit body 2 are filled with concrete. Then, swing the swing rod 28 to the right away from above the loading hopper 1, and then use the crane to pull the steel wire rope 30 and the plugging disc 31 upward out of the conduit body 2, so that the plugging disc 31 no longer blocks the lower end of the lowermost conduit body 2. At this time, the concrete in the conduit body 2 will fall downward into the pile hole to form a continuous concrete flow. At the same time, continuously pour concrete into the loading hopper 1 to replenish the concrete in the conduit body 2, which can ensure the continuous pouring of concrete. As the concrete is continuously poured, the conduit body 2 and the loading hopper 1 also need to be gradually lifted. During the lifting process of the conduit body 2, the roller 17 can roll upward along the inner wall of the steel reinforcement cage, so that the conduit body 2 always remains at the center position of the pile hole, preventing uneven pouring; when the pile hole pouring is completed, the loading hopper 1 and the conduit body 2 can be disassembled. First, push the sliding ring 10 downward, so that the telescopic rod 9 shortens, the connecting spring 11 is compressed, and the sliding ring 10 can drive the vertical rod 12 and the extrusion wheel 13 to move downward. The extrusion wheel 13 can roll along the inclined surface of the clamping block 7 to squeeze the clamping block 7 to move toward the inserting block 5, and the reset spring 8 is compressed, so that the bottom surface of the clamping block 7 on the lower conduit body 2 is separated from the lower end of the upper conduit body 2. Then, the two conduit bodies 2 can be separated. Then, release the sliding ring 10, and the connecting spring 11 returns to its original state, which can drive the sliding ring 10, the vertical rod 12 and the extrusion wheel 13 to move upward and reset, and the telescopic rod 9 elongates. Similarly, the loading hopper 1 can also be separated from the uppermost conduit body 2; at the same time, when the sliding ring 10 on the second conduit body 2 from the bottom up moves downward, it can also drive the fixed block 22 and the lifting shell 23 to move downward. When the lifting shell 23 contacts the ball 25, it can squeeze the ball 25 to move away from the center of the conduit body 2, driving the connecting frame 24 and the locking plate 20 to move away from the center of the conduit body 2, and the tension spring 21 is stretched, so that the locking plate 20 will be separated from the wedge-shaped block 18. At this time, the reset torsion spring 16 will return to its original state, driving the rotating plate 15 to rotate downward by ninety degrees and retract. The rotating plate 15 can drive the wedge-shaped block 18 and the roller 17 to rotate downward and reset. When the sliding ring 10 on the second conduit body 2 from the bottom up moves upward and resets, it can drive the fixed block 22 and the lifting shell 23 to move upward and reset, so that the lifting shell 23 is separated from the ball 25. At this time, the tension spring 21 returns to its original state, which can drive the locking plate 20, the connecting frame 24 and the ball 25 to move toward the center of the conduit body 2 and reset.;

These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be construed in any way as limiting the scope of protection of the embodiments of the present invention.
