Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a concrete pouring construction device and construction method. Background Technology

[0002] Currently, in the concrete pouring construction of bridge pile foundations, building foundation piles, and underground continuous walls, it is usually necessary to transport concrete through multiple pouring pipes. The pouring pipes are continuously raised or disassembled as the concrete level changes to ensure the continuity and stability of the pouring operation. Due to the long overall length and heavy weight of the pouring pipes, the positioning and connection operations often rely on construction personnel to cooperate with the hoisting equipment during the hoisting and connection process.

[0003] Most existing concrete pouring construction equipment only has basic support and guiding functions. When connecting the pouring pipe, it lacks an effective quick-limiting and locking structure, which makes the pouring pipe prone to displacement, shaking or misalignment during hoisting. This not only increases the difficulty of operation for construction personnel, but also easily affects the pouring efficiency and connection stability. In addition, when the pouring pipe suddenly slides down due to hook detachment, loose connection or abnormal wire rope, the existing equipment usually lacks a real-time detection mechanism for the descent speed, and cannot identify the abnormal falling state of the pouring pipe in time.

[0004] Meanwhile, existing equipment has limited protective measures against the rapid descent of the grouting pipe. Especially when the grouting pipe has a large inertia, it is easy to directly impact the inner wall of the pile hole or the lower structure, causing deformation and damage to the grouting pipe itself. In severe cases, it can also lead to pile hole collapse, hole wall damage, and interruption of concrete grouting, posing a significant construction safety hazard. Although some existing devices are equipped with limit mechanisms, most of them are passive rigid blocking structures. When faced with a heavy grouting pipe falling at high speed, it is difficult to effectively buffer and decelerate it, which can easily generate a large impact load.

[0005] Therefore, how to provide a concrete pouring construction device that can stably limit the connection of the pouring pipe, detect the descent speed in real time, and automatically limit the speed and buffer when the pouring pipe falls abnormally fast has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing a concrete pouring construction device and construction method.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A concrete pouring construction device includes a support frame, with a circular hole at the center of the top of the support frame for a pouring pipe to pass through, and further includes: There are two support plates, which are symmetrically and slidably mounted on the top of the support frame. Each support plate has a first spring rod fixed horizontally at both ends on one side, and the fixed end of the first spring rod is fixed to the top of the support frame. There are two locking components, which are set on the support plate and the support frame. The locking components are used to lock the support plate and limit the position of the injection tube to facilitate the connection between the injection tubes. There are two detection components, which are symmetrically arranged at the bottom of the support frame. The detection components are used to detect the speed of the vertical movement of the injection pipe, so as to prevent the injection pipe from detaching and falling rapidly, which could damage itself and the pile hole. There are two speed limiting components, which are symmetrically arranged at the bottom of the support frame. The speed limiting components are used to limit the speed of the rapidly descending injection pipe, so as to avoid the injection pipe from falling too rapidly due to excessive inertia.

[0008] As a further technical solution of the present invention, the locking component includes: a hook, which is installed at the center of the side of the support plate via a torsion shaft. A through slot is provided at the top of the support frame, and the hook can be inserted into the slot to limit the movement of the support plate. A top block is slidably provided inside the slot, and the top block is used to push the hook out from inside the slot to release the locking of the support plate.

[0009] As a further technical solution of the present invention, the detection component includes: a bracket, which is disposed below the support frame, and a detection roller is rotatably mounted at the end of the bracket. The detection roller is in contact with the surface of the injection pipe and is used to drive the detection roller to rotate when the injection pipe descends, so as to realize the conversion of the descent speed of the injection pipe. Two symmetrically arranged second spring rods are horizontally fixed at the bottom of the support frame, and the telescopic ends of the two second spring rods are fixed to the side of the bracket for limiting the bracket and the detection roller.

[0010] As a further technical solution of the present invention, a first gearbox is fixedly installed on each of the opposing sides of the bracket, and two symmetrically arranged second gearboxes are fixedly installed below the support frame. Two first bevel gears are rotatably installed inside the first gearbox, and two second bevel gears are rotatably installed inside the second gearbox. The two corresponding first bevel gears mesh with each other, and the two corresponding second bevel gears mesh with each other. Both ends of the detection roller are fixedly connected to the center of the end face of the two corresponding first bevel gears through connecting shafts, so as to drive the first bevel gears to rotate by rotating the detection roller.

[0011] As a further technical solution of the present invention, a first telescopic rod is horizontally arranged between the first gearbox and the second gearbox on the same side, and the telescopic end and the fixed end of the first telescopic rod are slidably connected by a spline. The two ends of the first telescopic rod are respectively installed at the center of the end face of the corresponding first bevel gear and the second bevel gear, so as to transmit the rotation of the first bevel gear to the second bevel gear through the first telescopic rod, and further make the second bevel gear rotate.

[0012] As a further technical solution of the present invention, a rotating rod is horizontally arranged between the two second gearboxes, and the two ends of the rotating rod are respectively installed at the center of the end face of the two corresponding second bevel gears, for driving the rotating rod to rotate through the second bevel gears. A fixed plate is fixedly sleeved at the center of the rotating rod surface, and both ends of the rotating rod are slidably sleeved with sliding discs through splines. The two sliding discs are located between the two first gearboxes. A collar is rotatably sleeved on the surface of each sliding disc. A first support rod is rotatably installed at the top of each collar, and the top of the first support rod is rotatably installed at the bottom of the top block, for changing the angle of the first support rod through the movement of the collar, thereby further moving the top block.

[0013] As a further technical solution of the present invention, a first movable rod is rotatably mounted on both sides of the fixed disk in a ring shape, and a counterweight is rotatably mounted on the other end of each first movable rod. A second movable rod is also rotatably mounted on the side of each counterweight, and the end of the corresponding second movable rod is rotatably mounted on the side of the corresponding sliding plate. When the rotating rod drives the fixed disk to rotate, the first movable rod and the second movable rod can drive the counterweight to rotate. The centrifugal force generated when the counterweight rotates will pull the sliding plate to move through the second movable rod, and further drive the top block to move upward.

[0014] As a further technical solution of the present invention, the speed limiting component includes: a deceleration block, which is disposed below the support frame. The starting position of the deceleration block does not contact the injection pipe. A third spring rod is horizontally fixed on the end face of the deceleration block, and the third spring rod is fixed to the bottom of the support frame through a connecting plate. It is used to support and limit the deceleration block, thereby ensuring the stability of the deceleration block.

[0015] As a further technical solution of the present invention, the telescopic end and the fixed end of the third spring rod are slidably connected by a spline, and a limiting hole for observation is provided on the telescopic end of the third spring rod. A second telescopic rod is vertically installed at the bottom of the support frame, and the telescopic end and the fixed end of the second telescopic rod are slidably connected by a spline. The telescopic end of the second telescopic rod can be inserted into the limiting hole, and an L-shaped rod is fixed on the surface of the telescopic end of the second telescopic rod. The vertical side of the L-shaped rod is fixed to the bottom of the top block to realize the storage and limiting of the third spring rod. When the injection tube descends too fast, the support plate and the deceleration block will move rapidly to decelerate and block the injection tube.

[0016] A concrete pouring construction method includes the following steps: S1: When grouting is required in the pile hole, first place the support frame at the pile hole, then move the two support plates in opposite directions and lock the hook inside the slot. At this time, the first spring rod generates elastic force. Then, the grouting pipe is lifted by the crane and passed through the round hole. Finally, lift the hook upward to release the lock on the support plate. The support plate will then reset to support and limit the grouting pipe. When splicing the grouting pipe is required, after the crane lifts the grouting pipe, the two grouting pipes can be connected by threads. The grouting pipe can be installed during the grouting construction.

[0017] S2: During the splicing of the grouting pipe, the crane and the grouting pipe may become detached, causing the grouting pipe to fall rapidly, which may damage the grouting pipe and the pile hole.

[0018] S3: When the injection tube falls rapidly, it will cause the detection roller to rotate faster. The rotation of the detection roller will cause the first bevel gear to rotate faster. The rotation of the first bevel gear will cause the first telescopic rod to rotate faster. The function of the first telescopic rod is to transmit the rotation of the first bevel gear to the second bevel gear, while also allowing the support to move horizontally to avoid affecting the contact between the detection roller and the injection tube. The rotation of the first telescopic rod will cause the second bevel gear to rotate faster. The rotation of the second bevel gear will cause the rotating rod to rotate faster. The rotation of the rotating rod will cause the fixed plate and the sliding plate to rotate faster. The further rotation of the fixed plate and the sliding plate will cause the first movable rod, the second movable rod and the counterweight to rotate faster. Due to centrifugal force, the counterweight will move away from the rotating rod after being subjected to centrifugal force. The movement of the counterweight will cause the sliding plate to move through the first movable rod. The movement of the sliding plate will cause the collar to move. The movement of the collar will cause the first support rod to move. The movement of the two first support rods will cause the top block to move upward. The upward movement of the top block can not only push the hook out of the slot, but also drive the L-shaped rod to move upward. S4: After the hook is pushed out of the slot, the elastic force generated by the first spring rod will cause the support plate to quickly reset, so as to support and limit the rapidly falling injection tube. The upward movement of the L-shaped rod will drive the extension end of the second telescopic rod to move upward. The extension end of the second telescopic rod will move out of the limiting hole, which will release the limitation of the third spring rod. Furthermore, the elastic force generated by the third spring rod will cause the deceleration block to fit with the injection tube, so as to decelerate the injection tube and reduce the impact force between the injection tube and the support plate after the support plate resets.

[0019] The beneficial effects of this invention are as follows: This invention, by setting up a support plate, hook, top block, detection roller, bevel gear transmission structure, and counterweight linkage structure, can quickly limit and stably lock the injection pipe during normal hoisting and connection, preventing the injection pipe from shifting and shaking during connection. At the same time, the detection roller is used to convert the descent speed of the injection pipe in real time, and the top block is driven to move through centrifugal linkage to realize the automatic release of the locked state. Thus, it can respond in time when the injection pipe descends abnormally rapidly, thereby improving the stability, automation level, and construction safety of the injection pipe connection process.

[0020] This invention, by incorporating a deceleration block, a third spring rod, a second telescopic rod, and a limiting linkage structure, automatically releases the deceleration block when the grouting pipe descends too quickly. This allows the deceleration block to quickly approach the grouting pipe and buffer and decelerate it, effectively reducing the inertial impact generated by the rapid descent of the grouting pipe. This prevents the grouting pipe from directly impacting the pile hole or causing structural damage, while also reducing the impact on the inner wall of the pile hole and construction equipment, thus improving the protective capabilities and construction reliability during concrete grouting.

There are two speed limiting assemblies, symmetrically mounted at the bottom of the support frame 1, used to limit the speed of the rapidly descending pouring pipe, preventing excessive inertia during rapid descent.

[0026] Please see the appendix Figure 1 -Appendix Figure 2In a preferred embodiment, the locking component includes: a hook 3, which is mounted on the center of the side of the support plate 2 via a torsion shaft. The top of the support frame 1 has a through slot 7, which can be inserted into the slot 7 to limit the movement of the support plate 2. A top block 8 is slidably disposed inside the slot 7, and the top block 8 is used to push the hook 3 out from inside the slot 7 to release the lock on the support plate 2.

[0027] Please see the appendix Figure 2 -Appendix Figure 4 In a preferred embodiment, the detection component includes: a bracket 10, which is disposed below the support frame 1, and a detection roller 9 is rotatably mounted at the end of the bracket 10. The detection roller 9 is in contact with the surface of the injection tube and is used to drive the detection roller 9 to rotate when the injection tube descends, so as to realize the conversion of the descent speed of the injection tube. Two symmetrically arranged second spring rods 15 are horizontally fixed at the bottom of the support frame 1, and the telescopic ends of the two second spring rods 15 are fixed to the side of the bracket 10 for limiting the bracket 10 and the detection roller 9.

[0028] Please see the appendix Figure 2 -Appendix Figure 8 In a preferred embodiment, a first gearbox is fixedly installed on each of the opposite sides of the bracket 10, and two symmetrically arranged second gearboxes are fixedly installed below the support frame 1. Two first bevel gears 24 are rotatably installed inside the first gearbox, and two second bevel gears 25 are rotatably installed inside the second gearbox. The two corresponding first bevel gears 24 mesh with each other, and the two corresponding second bevel gears 25 mesh with each other. Both ends of the detection roller 9 are fixedly connected to the center of the end face of the two corresponding first bevel gears 24 through connecting shafts, so as to drive the first bevel gears 24 to rotate by rotating the detection roller 9.

[0029] Please see the appendix Figure 5 -Appendix Figure 8 In a preferred embodiment, a first telescopic rod 5 is horizontally arranged between the first gearbox and the second gearbox on the same side, and the telescopic end and the fixed end of the first telescopic rod 5 are slidably connected by a spline. The two ends of the first telescopic rod 5 are respectively installed at the center of the end face of the corresponding first bevel gear 24 and second bevel gear 25, so as to transmit the rotation of the first bevel gear 24 to the second bevel gear 25 through the first telescopic rod 5, and further make the second bevel gear 25 rotate.

[0030] Please see the appendix Figure 2 -Appendix Figure 8In a preferred embodiment, a rotating rod 12 is horizontally arranged between the two second gearboxes, and the two ends of the rotating rod 12 are respectively installed at the center of the end face of the two corresponding second bevel gears 25, for driving the rotating rod 12 to rotate through the second bevel gears 25. A fixed plate 19 is fixedly sleeved at the center of the surface of the rotating rod 12, and both ends of the rotating rod 12 are slidably sleeved with a sliding plate 20 through a spline. The two sliding plates 20 are located between the two first gearboxes. A collar 21 is rotatably sleeved on the surface of each sliding plate 20. A first support rod 13 is rotatably installed at the top of each collar 21, and the top of the first support rod 13 is rotatably installed at the bottom of the top block 8, for changing the angle of the first support rod 13 through the movement of the collar 21, thereby further moving the top block 8.

[0031] Please see the appendix Figure 2 -Appendix Figure 5 In a preferred embodiment, the fixed disk 19 is rotatably mounted with first movable rods 22 on both sides in a ring shape, and a counterweight 27 is rotatably mounted on the other end of each first movable rod 22. A second movable rod 23 is also rotatably mounted on the side of each counterweight 27, and the end of the corresponding second movable rod 23 is rotatably mounted on the side of the corresponding slide 20. When the rotating rod 12 drives the fixed disk 19 to rotate, the first movable rods 22 and the second movable rods 23 can drive the counterweight 27 to rotate. The centrifugal force generated when the counterweight 27 rotates will pull the slide 20 to move through the second movable rods 23, and further drive the top block 8 to move upward.

[0032] Please see the appendix Figure 1 -Appendix Figure 6 In a preferred embodiment, the speed limiting component includes: a deceleration block 11, which is disposed below the support frame 1. The deceleration block 11 is not in contact with the injection pipe at its initial position. A third spring rod 16 is horizontally fixed to the end face of the deceleration block 11, and the third spring rod 16 is fixed to the bottom of the support frame 1 through a connecting plate. It is used to support and limit the deceleration block 11, thereby ensuring the stability of the deceleration block 11.

[0033] Please see the appendix Figure 1 -Appendix Figure 8 In a preferred embodiment, the telescopic end and the fixed end of the third spring rod 16 are slidably connected by a spline, and a limiting hole 18 for observation is provided on the telescopic end of the third spring rod 16. A second telescopic rod 17 is vertically installed at the bottom of the support frame 1, and the telescopic end and the fixed end of the second telescopic rod 17 are slidably connected by a spline. The telescopic end of the second telescopic rod 17 can be inserted into the limiting hole 18, and an L-shaped rod 14 is fixed on the surface of the telescopic end of the second telescopic rod 17. The vertical side of the L-shaped rod 14 is fixed to the bottom of the top block 8 to realize the storage and limiting of the third spring rod 16. When the injection tube descends too fast, the support plate 2 and the deceleration block 11 will move quickly to decelerate and block the injection tube.

[0034] When grouting is required in the pile hole, first place the support frame 1 at the pile hole, then move the two support plates 2 in opposite directions and lock the hook 3 into the slot 7. At this time, the first spring rod 4 generates elastic force. Then, the grouting pipe is lifted by the crane and passed through the round hole 26. Finally, the hook 3 is lifted up to release the lock on the support plate 2. The support plate 2 will then reset to support and limit the grouting pipe. When splicing the grouting pipe is required, after the crane lifts the grouting pipe, the two grouting pipes can be connected by threads. In summary, the grouting pipe can be installed during grouting construction.

[0035] During the splicing of the grouting pipe, the crane and the grouting pipe may become detached, causing the grouting pipe to fall rapidly and potentially damaging both the grouting pipe and the pile hole.

[0036] When the injection tube falls rapidly, it causes the detection roller 9 to rotate at an accelerated speed. The rotation of the detection roller 9 causes the first bevel gear 24 to rotate at an accelerated speed. The accelerated rotation of the first bevel gear 24 causes the first telescopic rod 5 to rotate at an accelerated speed. The function of the first telescopic rod 5 is to transmit the rotation of the first bevel gear 24 to the second bevel gear 25, while also allowing the support 10 to move laterally horizontally, so as not to affect the contact between the detection roller 9 and the injection tube. The accelerated rotation of the first telescopic rod 5 causes the second bevel gear 25 to rotate at an accelerated speed. The accelerated rotation of the second bevel gear 25 causes the rotating rod 12 to rotate at an accelerated speed. The accelerated rotation of the rotating rod 12 causes the fixed plate 19 and the sliding plate to rotate at an accelerated speed. The accelerated rotation of the rotating rod 12, along with the accelerated rotation of the fixed plate 19 and the sliding plate 20, will drive the first movable rod 22, the second movable rod 23, and the counterweight 27 to rotate faster. Due to centrifugal force, the counterweight 27 will move away from the rotating rod 12 after being subjected to centrifugal force. The movement of the counterweight 27 will drive the sliding plate 20 to move through the first movable rod 22. The movement of the sliding plate 20 will drive the collar 21 to move. The movement of the collar 21 will drive the first support rod 13 to move. The movement of the two first support rods 13 will drive the top block 8 to move upward. The upward movement of the top block 8 can not only push the hook 3 out of the slot 7, but also drive the L-shaped rod 14 to move upward. After the hook 3 is pushed out from the slot 7, the elastic force generated by the first spring rod 4 will cause the support plate 2 to quickly return to its original position, so as to support and limit the rapidly falling injection tube. Moving the L-shaped rod 14 upwards will cause the telescopic end of the second telescopic rod 17 to move upwards. The telescopic end of the second telescopic rod 17 will move out of the limiting hole 18, which will release the limiting of the third spring rod 16. Furthermore, the elastic force generated by the third spring rod 16 will cause the deceleration block 11 to fit with the injection tube, thereby decelerating the injection tube and reducing the impact force between the injection tube and the support plate 2 after the support plate 2 is reset.

[0037] In summary, the system can detect the descent speed of the grouting pipe when it is unhooked from the crane, and can automatically decelerate and limit the grouting pipe after detection, thus preventing the grouting pipe from falling rapidly into the pile hole and damaging both the grouting pipe and the pile hole, thereby improving the safety and effectiveness of the grouting construction.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

S3: When the injection tube falls rapidly, it will drive the detection roller (9) to rotate faster. The rotation of the detection roller (9) will drive the first bevel gear (24) to rotate faster. The rotation of the first bevel gear (24) will drive the first telescopic rod (5) to rotate faster. The function of the first telescopic rod (5) is to transmit the rotation of the first bevel gear (24) to the second bevel gear (25) while also allowing the support (10) to move laterally horizontally, so as not to affect the contact between the detection roller (9) and the injection tube. The rotation of the first telescopic rod (5) will drive the second bevel gear (25) to rotate faster. The rotation of the second bevel gear (25) will drive the rotating rod (12) to rotate faster. The rotation of the rotating rod (12) will drive the fixed plate (19) and the sliding plate (20) to rotate faster. The accelerated rotation of the fixed plate (19) and the sliding plate (20) will drive the first movable rod (22), the second movable rod (23) and the counterweight (27) to rotate faster. Due to the centrifugal force, the counterweight (27) will move away from the rotating rod (12) after being subjected to centrifugal force. The movement of the counterweight (27) will drive the sliding plate (20) to move through the first movable rod (22). The movement of the sliding plate (20) will drive the collar (21) to move. The movement of the collar (21) will drive the first support rod (13) to move. The movement of the two first support rods (13) will drive the top block (8) to move upward. The upward movement of the top block (8) can not only push the hook (3) out from the slot (7), but also drive the L-shaped rod (14) to move upward. S4: After the hook (3) is pushed out from the slot (7), the elastic force generated by the first spring rod (4) will cause the support plate (2) to quickly reset, so as to support and limit the rapidly falling injection tube. The L-shaped rod (14) moves upward, which will drive the extension end of the second telescopic rod (17) to move upward. The extension end of the second telescopic rod (17) will move out of the limiting hole (18), which will release the limitation on the third spring rod (16). Furthermore, the elastic force generated by the third spring rod (16) will cause the deceleration block (11) to fit with the injection tube, so as to decelerate the injection tube and reduce the impact force between the injection tube and the support plate (2) after the support plate (2) is reset.
