Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring, in particular to a concrete pouring device used for pile foundation engineering construction. Background Art

[0002] Pile foundation engineering is a common form of deep foundation, which is mainly used to transfer the load of the building to the deep soil or rock underground to provide stable support. Concrete pouring is a key process in the construction of pile foundation engineering, which is to pour the mixed concrete into pre-prepared molds to form structural components.

[0003] For example, "A concrete pouring device for pile foundation engineering construction" with publication number CN117090211B includes a mobile base, a breaking up mechanism, an extending and diffusing mechanism and a vertical guiding mechanism. The interior of the mobile base is fixedly connected to a mounting frame, and one side of the mounting frame is fixedly connected to a connecting frame by bolts.

[0004] However, in the prior art, during the concrete pouring process, too fast a speed will cause more air to be wrapped in the concrete. The air accumulates in the concrete, which will cause bubbles to be generated inside the pile body during the subsequent cooling and molding process. The presence of bubbles will directly affect the structural strength of the pile body, causing the pile body to fail to meet the use standards, which will directly slow down the construction progress of the entire pile foundation project.

[0015] Preferably, a bearing plate is fixedly mounted on the top of the first supporting frame, a threaded rod is rotatably mounted inside the bearing plate, and one end of the threaded rod is fixedly connected to an electric motor.

[0016] Preferably, the electric motor is fixedly mounted on the bottom of the first supporting frame, a movable block is threadedly connected to the outer wall of the threaded rod, and the bottom of the movable block is fixedly connected to the top of the limiting block.

[0017] Preferably, one side of the counterweight plate is rotatably connected to an electric cylinder, and the electric cylinder is located on one side of the second supporting frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, before pouring concrete, the first rotating rod and the second rotating rod are driven simultaneously by a reduction motor, and the rotation of the first rotating rod and the second rotating rod will complete the cutting of concrete through the spiral cutting plates on their outer walls, and release the air contained in the concrete by continuously cutting the concrete. By releasing the air from the concrete, the air content in the concrete is reduced, so as to avoid the generation of bubbles in the subsequent concrete cooling and molding process, thereby ensuring the structural strength of the pile body after molding and ensuring that it will not affect the construction progress of the pile foundation project. The first rotating rod and the second rotating rod are adjacent to each other, and the concrete cut by the spiral cutting plate on the first rotating rod will contact the spiral cutting plate on the second rotating rod, and the rotation direction of the first rotating rod is completely opposite to that of the second rotating rod, and reverse cutting can greatly improve the exhaust speed and quality.

[0020] 2. In the design of the concrete mixing and conveying system of the present invention, the mixing chamber is set to a conical structure, so that the concrete raw materials entering from all directions can naturally converge at the tip of the cone to form a compact and efficient mixing area. In this area, the concrete raw materials are closely contacted and squeezed with each other, which not only promotes the uniform mixing of the various components, but also effectively forces the air contained in the concrete to be discharged to the outside, further reducing the air content in the concrete, thereby improving the quality and density of the concrete. A horizontal connecting pipe is set at the bottom of the mixing chamber. This pipe not only connects the mixing chamber and the unloading chamber, but also ensures that the concrete can smoothly enter the next processing chamber. In this stage, a bending structure is adopted inside the unloading chamber. Based on fluid mechanics and material mechanics, three changing-direction structures are arranged in sequence, which not only provides additional extrusion opportunities for concrete and ensures that each part of concrete can be fully mixed and exhausted, but also cleverly slows down the unloading speed of concrete, avoiding the problem of air re-entrainment caused by excessive concrete pouring speed. In the process of rapid pouring, tiny bubbles in the surrounding air may be re-absorbed into the concrete due to excessive flow speed. If these bubbles are not effectively removed, they will have an adverse effect on the strength and durability of the concrete. By slowing down the unloading speed and combining multiple changing-direction extrusions inside the unloading chamber, the residual air in the concrete can be completely removed.

[0021] 3. In the present invention, when the electric motor starts and drives the threaded rod to rotate, the threaded rod serves as a core transmission component, and its rotational motion is converted into a linear movement of the movable block in the vertical direction through the interaction between the thread and the movable block, thereby realizing dynamic adjustment of the height of the pouring assembly, ensuring that the pouring assembly can maintain the best working position and posture regardless of how the depth of the foundation changes, thereby ensuring the smooth progress of the pouring operation and the consistency of the pile quality. The first support frame serves as the main structure of the entire pouring device. In order to further enhance the stability of the first support frame, a second support frame is added to its side. The second support frame The frame not only provides an additional support point for the first support frame, but also improves the overall stability of the first support frame through its internal counterweight plate. The existence of the counterweight plate effectively balances the various forces and moments that may be generated by the device during the pouring process, and prevents the device from shaking or overturning due to external forces. The counterweight plate is also connected to the electric cylinder. By controlling the extension and retraction of the electric cylinder, the position of the counterweight plate can be fine-tuned, and then the angle of the first support frame can be adjusted. The angle adjustment function can adapt to complex terrain or special working conditions, to adapt to different construction environments and requirements, and ensure that the pouring operation is carried out efficiently, accurately and safely.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown: a concrete pouring device for pile foundation engineering construction, comprising a first support frame 1 and a second support frame 5, a connecting frame 4 is fixedly connected between the first support frame 1 and the second support frame 5, and a pouring assembly 2 is fixedly installed inside the first support frame 1;

[0033] The pouring assembly 2 includes a feed chamber 21, a mixing chamber 27 and a discharge chamber 23. One end of the feed chamber 21 is fixedly connected to one end of the mixing chamber 27. The mixing chamber 27 is configured to be conical. One end of the mixing chamber 27 is fixedly connected to a connecting pipe 214. One end of the connecting pipe 214 is fixedly connected to one end of the discharge chamber 23. Both sides of the feed chamber 21 are fixedly connected to a delivery pipe 3. The delivery pipe 3 is connected to an external concrete delivery device.

[0034] A reduction motor 26 is fixedly installed on the top of the feed chamber 21, and the output end of the reduction motor 26 is fixedly connected to the first rotating rod 29. A second rotating rod 210 is rotatably installed inside the feed chamber 21. Spiral cutting plates 212 are fixedly installed on the outer walls of the first rotating rod 29 and the outer walls of the second rotating rod 210. The second rotating rod 210 is located on one side of the first rotating rod 29.

[0035] In this embodiment, the pouring assembly 2 is fixedly installed in the first supporting frame 1, and a connecting frame 4 is fixedly connected between the first supporting frame 1 and the second supporting frame 5 to ensure the overall structural stability of the device;

[0036] The feed chamber 21 in the pouring assembly 2 is connected to the external concrete conveying device through the conveying pipe 3, and the concrete is continuously conveyed into the feed chamber 21 through the conveying pipe 3. In this process, the reduction motor 26 drives the first rotating rod 29, and the first rotating rod 29 drives the second rotating rod 210 at the same time. The rotation of the first rotating rod 29 and the second rotating rod 210 will cut the concrete through the spiral cutting plate 212 on the outer wall thereof;

[0037] When the spiral cutting plate 212 cuts the concrete, the air contained in the concrete will be released, so as to reduce the air content in the concrete. In the subsequent cooling and molding process of the concrete, no bubbles will be generated, so as to ensure the structural strength of the pile body after molding and ensure that the construction progress of the pile foundation project will not be affected.

[0038] The first rotating rod 29 and the second rotating rod 210 are adjacent to each other. The concrete cut by the spiral cutting plate 212 on the first rotating rod 29 will contact the spiral cutting plate 212 on the second rotating rod 210. After the spiral cutting plate 212 on the second rotating rod 210 has cut the concrete, the concrete will contact the spiral cutting plate 212 on the first rotating rod 29 again. The reciprocating movement and staggered cutting can greatly improve the exhaust speed and quality.

[0039] After the air is exhausted, the concrete will be concentrated into the mixing chamber 27, and then discharged into the discharge chamber 23 from the connecting pipe 214. In this process, due to the presence of multiple bending structures in the connecting pipe 214 and the discharge chamber 23, the multiple change-of-direction structures can ensure that the concrete is fully squeezed. At the same time, the overall concrete discharge speed can be slightly slowed down to prevent the concrete pouring speed from being too fast, ensuring that no air will be entrained in the final pouring process.

[0040] Embodiment 2: According to Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, bearing seats 213 are fixedly installed at the intersection of the first rotating rod 29 and the feed chamber 21, and at the intersection of the second rotating rod 210 and the feed chamber 21. The bearing seats 213 are located at the upper and lower ends of the feed chamber 21. A first gear 215 is fixedly installed at one end of the first rotating rod 29, and a second gear 211 is fixedly installed at one end of the second rotating rod 210. The first gear 215 and the second gear 211 are meshingly connected. A hollow shell 28 is fixedly installed at the bottom of the feed chamber 21. The first gear 215 and the second gear 211 are both located inside the hollow shell 28, and the discharge chamber 23 is located on one side of the hollow shell 28.

[0041] In this embodiment, the first rotating rod 29 and the second rotating rod 210 are installed in the feed chamber 21 through the bearing seat 213. This installation method not only ensures the stability of the rotating rod during rotation, but also reduces the heat and wear generated by friction. The first gear 215 at the end of the first rotating rod 29 and the second gear 211 at the end of the second rotating rod 210 are meshed and connected to realize the transmission of power from one rotating rod to another. The gear transmission method has the advantages of accurate transmission ratio, high transmission efficiency and compact structure.

[0042] When the first rotating rod 29 is driven by the reduction motor 26 to start rotating, the first gear 215 at the end thereof will rotate accordingly. Since there is a meshing relationship between the first gear 215 and the second gear 211, the second gear 211 will be pushed by the first gear 215 and start rotating. The rotation direction of the second gear 211 is opposite to that of the first gear 215, thereby realizing the reverse rotation of the second rotating rod 210. The first gear 215 and the second gear 211 are both arranged in the hollow housing 28, which provides effective protection for the gears. The hollow housing is made of stainless steel or aluminum alloy.

[0043] The concrete cut by the spiral cutting plate 212 on the first rotating rod 29 will contact the spiral cutting plate 212 on the second rotating rod 210. After the spiral cutting plate 212 on the second rotating rod 210 cuts the concrete, the concrete will contact the spiral cutting plate 212 on the first rotating rod 29 again, thereby improving the speed and quality of exhaust.

[0044] Embodiment 3: According to Figure 2 , Figure 3 and Figure 4As shown, a connecting block 24 is fixedly installed on the top of the feed chamber 21, and a limiting block 25 is fixedly installed on the top of the connecting block 24. The limiting block 25 is slidably connected to the first supporting frame 1. A protective frame 22 is fixedly installed on the outer wall of the feed chamber 21, and the protective frame 22 is fixedly connected to the first supporting frame 1. A supporting plate 10 is fixedly installed on the top of the first supporting frame 1, and a threaded rod 12 is rotatably installed inside the supporting plate 10. One end of the threaded rod 12 is fixedly connected to an electric motor 11, and the electric motor 11 is fixedly installed on the bottom of the first supporting frame 1. A movable block 13 is threadedly connected to the outer wall of the threaded rod 12, and the bottom of the movable block 13 is fixedly connected to the top of the limiting block 25.

[0045] In this embodiment, the feed chamber 21 is preliminarily connected to the first support frame 1 through the connecting block 24. The existence of the protection frame 22 ensures the stability of the feed chamber 21 in the horizontal direction, and the limit block 25 further enhances the stability of the connection. It is fixedly connected to the bottom of the movable block 13 and indirectly connected to the threaded rod 12 to form a dynamic support system.

[0046] During the pouring process, as the foundation depth increases, the feed chamber 21 needs to be lowered accordingly to meet the pouring requirements. At this time, the electric motor 11 is started to drive the threaded rod 12 to rotate. Since there is a threaded fit between the movable block 13 and the threaded rod 12, the movable block 13 will move along the direction of the threaded rod 12, so that the feed chamber 21 can achieve a high degree of dynamic adjustment during the pouring process, ensuring that the pouring material can be accurately delivered to the designated position. The bearing plate 10, as a fixed structure on the top of the first support frame 1, not only provides a stable installation foundation for the threaded rod 12, but also ensures the stability of the entire support frame during the pouring process through its rigidity and strength;

[0047] The unloading chamber 23 is slidably connected to the inner side of the first supporting frame 1. This design allows the unloading chamber 23 to maintain a relatively stable position relationship when the feeding chamber 21 descends. At the same time, the sliding connection between the unloading chamber 23 and the first supporting frame 1 also has a certain buffering effect, which can reduce the impact force and vibration generated by the descent of the feeding chamber 21 on the unloading chamber and the entire casting assembly 2.

[0048] Embodiment 4: According to Figure 1 , Figure 2 and Figure 3As shown, a counterweight plate 6 is movably installed inside the second support frame 5, a reinforcement frame 9 is fixedly installed on the bottom of the second support frame 5, one end of the counterweight plate 6 is fixedly installed inside the reinforcement frame 9 by bolts, one end of the reinforcement frame 9 is fixedly connected to a triangular support frame 8, one end of the triangular support frame 8 is fixedly connected to one side of the first support frame 1 by bolts, one side of the counterweight plate 6 is rotatably connected to an electric cylinder 7, and the electric cylinder 7 is located on one side of the second support frame 5.

[0049] In this embodiment, the reinforcement frame 9 is used to enhance the connection strength between the second support frame 5 and the first support frame 1. A triangular support frame 8 is also provided on the side of the reinforcement frame 9 to further enhance the structural strength. The counterweight plate 6 located in the second support frame 5 can maintain the overall balance of the device, thereby achieving the effect of maintaining the stability of the first support frame 1. In addition, the counterweight plate 6 is also connected to the electric cylinder 7. The extension and retraction of the piston rod in the electric cylinder 7 can adjust the angle of the first support frame 1.

[0050] The use method and working principle of the device: the external concrete conveying device continuously conveys concrete to the feeding chamber 21 through the conveying pipe 3. When the concrete is in the feeding chamber 21, the reduction motor 26 drives the first rotating rod 29, and the first rotating rod 29 drives the second gear 211 through the first gear 215, thereby driving the second rotating rod 210 to rotate in the opposite direction;

[0051] The rotation of the first rotating rod 29 and the second rotating rod 210 will cut the concrete through the spiral cutting plates 212 on the outer walls thereof. When the spiral cutting plates 212 cut the concrete, the air contained in the concrete will be released, thereby achieving the purpose of reducing the air content in the concrete. The first rotating rod 29 and the second rotating rod 210 are adjacent to each other. The concrete cut by the spiral cutting plates 212 on the first rotating rod 29 will contact the spiral cutting plates 212 on the second rotating rod 210. After the spiral cutting plates 212 on the second rotating rod 210 have cut the concrete, the concrete will contact the spiral cutting plates 212 on the first rotating rod 29 again, thereby improving the speed and quality of exhaust.

[0052] After the air is exhausted, the concrete will be concentrated into the mixing chamber 27, and then discharged into the unloading chamber 23 from the connecting pipe 214. In this process, the concrete will contact the bending structure, so as to be fully squeezed, so as to prevent the concrete pouring speed from being too fast, and ensure that no air will be entrained in the final pouring process;

[0053] During the pouring process, the counterweight plate 6 located in the second support frame 5 can maintain the overall balance of the device, thereby maintaining the stability of the first support frame 1. In addition, if the pouring depth is deeper, the threaded rod 12 can be driven by the electric motor 11 to drive the movable block 13 to move downward along the direction of the threaded rod 12, thereby ensuring that the pouring assembly 2 can adapt to a deeper foundation, and the extension and retraction of the piston rod in the electric cylinder 7 can adjust the angle of the first support frame 1.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
