Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a multifunctional mixing pipe head vibration device. Background Technology

[0002] During construction, concrete pouring is required. This involves mixing concrete and then transporting it to a designated location using pumping equipment and mixing pipes. In existing technologies, the pumping pipes can only discharge the concrete; the concrete falls freely onto the reinforcing bars and then to the pouring location. This results in uneven spreading, and even after manual vibration to compact it, several more rounds of compaction are needed before reaching the final pouring point. Furthermore, the concrete is not sufficiently dense internally, and localized areas where cement slurry adheres to the reinforcing bars can lead to uneven aggregate distribution, making it prone to cracking later. The need for manual vibration combined with equipment results in low work efficiency. If a device could be designed that eliminates the need for manual vibration, using vibration to ensure even spreading and internal compaction of the concrete, both pouring quality and work efficiency could be significantly improved. Utility Model Content

[0003] In view of this, the present invention provides a multifunctional mixing pipe head spreading and vibrating device to solve the technical problems in the prior art that the pumping pipe cannot achieve one-time pouring and uniform spreading, resulting in insufficient internal compaction of concrete and subsequent cracking, as well as the need for manual vibration leading to low work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A multifunctional mixing pipe head vibrating device includes:

[0006] The conveying pipe is connected to the mixing pipe of the pump via a connecting structure;

[0007] A cone-shaped separator, located inside the delivery pipe;

[0008] A vibrating rod assembly, comprising a protective structure and a vibrating structure both fixed to the separating member, wherein the protective structure is located outside the vibrating structure.

[0009] Furthermore, the vibration structure includes:

[0010] The lower connecting screw passes through the steel plate of the separating component;

[0011] A rubber rod, which is sleeved on the lower connecting screw;

[0012] At least one first locking nut is threadedly connected to the lower end of the lower connecting screw to limit the position of the rubber rod.

[0013] Furthermore, the protective structure includes a vibrating rod outer tube, which is fixedly connected to the lower end of the separating member, and the vibrating rod outer tube surrounds the vibrating structure.

[0014] Furthermore, a steel plate is installed at the bottom of the separating component, the outer tube of the vibrating rod is fixedly connected to the steel plate, and the lower end of the lower connecting screw passes through the steel plate.

[0015] Furthermore, the connection structure includes:

[0016] A rotating cap that can fit around the connection between the conveying pipe and the mixing pipe;

[0017] A movable piece, which can be disposed at the opening of the rotating cap;

[0018] A pair of upper connecting screws, which can be inserted into a pair of holes in the rotating cap, to limit the movement of the movable piece;

[0019] A pair of second locking nuts, the second locking nuts being threadedly connected to the lower end of the corresponding upper connecting screw.

[0020] Furthermore, the rotating cap includes a pair of arc-shaped rotating plates, one end of which is hinged and the other end has an integrally connected flange. The upper connecting screw is connected to the corresponding flange, and the insertion hole is provided on the flange.

[0021] Furthermore, the movable piece has two through holes, which communicate with the corresponding insertion holes to facilitate the passage of the upper connecting screw.

[0024] Furthermore, the separating element is an isolation tube.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This invention employs a structure that integrates a conveying pipe, a separating component, and a vibrating rod assembly. The conveying pipe transports the concrete, while the separating component disperses and evenly spreads it. The vibrating principle of the mixing pipe's discharge vibration guides and drives the vibrating rod assembly, reducing the need for vibrators and other equipment. The vibrating rod assembly ensures uniform compaction of the concrete in a single pass (especially important for beams where multiple pours are unnecessary), increasing the concrete's internal density and reducing later cracking, thus improving construction quality. Furthermore, the entire process requires no manual operation, resulting in high efficiency. Additionally, this invention utilizes a convenient and secure connection structure to link the conveying pipe and the mixing pipe, enabling rapid installation and disassembly on-site, thereby shortening the construction period and increasing efficiency.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] refer to Figures 1 to 9 ,like Figure 1 As shown, this embodiment provides a multifunctional mixing pipe head vibration device, which mainly consists of a conveying pipe 4, a conical separating component, a vibrating rod assembly, and a connecting structure that is easy to disassemble. The conveying pipe 4 consists of an integrally connected connecting section 41 and a trumpet section 42. The connecting section 41 is a straight pipe, and the trumpet section 42 is a reducing pipe with a smaller diameter at the top and a larger diameter at the bottom. The upper end of the connecting section 41 is spliced ​​with the lower end of the mixing pipe 1 of the pump (such as a ground pump or a truck pump), and both the upper end of the connecting section 41 and the lower end of the mixing pipe 1 are fitted with connecting flanges. The two connecting flanges 2 can be fixed together by clamps or by bolts and nuts. The connecting structure surrounds the outside of the connecting section 41 and the mixing pipe 1, which can fix the conveying pipe 4 and the mixing pipe 1 together, thereby realizing the conveying of concrete. In this embodiment, the separating component is an isolation pipe 5, which is also a horn structure. A steel plate 51 is welded to the lower end of the isolation pipe 5, and the vibrating rod assembly is installed on the steel plate 51. Several annularly distributed connecting plates 52 are welded to the outer periphery of the steel plate 51. The connecting plates 52 are connected to the lower edge of the horn section 42, thereby realizing the installation between the separating component and the conveying pipe. The mixing pipe 1 can convey concrete under the action of the pump. The isolation pipe 5 is set inside the conveying pipe 4. The conical isolation pipe 5 can disperse the concrete sent into the conveying pipe 4 through the mixing pipe 1, making it spread evenly in multiple directions. The vibrating rod assembly is connected to the conveying pipe 4. The concrete has a very large vibration force when it is conveyed. The vibration force will cause the vibrating rod assembly to vibrate. The vibration can vibrate the concrete, making the concrete more compact and thus making the pouring more uniform.

[0039] Preferably, a protective structure consisting of rubber gaskets 3 is provided between the two connecting flanges 2. The rubber gaskets 3 can protect the connection between the horn section 4 and the mixing pipe 1, reduce the possibility of loosening of the connection between the horn section 4 and the mixing pipe 1 due to vibration, thereby preventing cracking at the connection due to vibration and extending the service life. Moreover, rubber material is simple to process and low in cost, so it is suitable for long-term use.

[0040] like Figure 4 , Figure 5 , Figure 7 , Figure 8As shown, the vibrating rod assembly mainly consists of a protective structure and a vibration structure, both fixed to the steel plate 51. The protective structure is located outside the vibration structure. The vibration structure mainly consists of a lower connecting screw 13, a hollow rubber rod 8, and at least one first locking nut 14. Before welding the steel plate 51 to the isolation tube 5, a hole is drilled in the steel plate 51, and the lower end of the T-shaped lower connecting screw 13 passes through this hole (a washer can be optionally installed on the lower connecting screw 13). Then, the steel plate 51 is welded to the isolation tube 5. Afterward, the hollow rubber rod 8 is fitted onto the lower connecting screw 13. The length of the rubber rod 8 is shorter than that of the lower connecting screw 13. Therefore, the first locking nut 14 is threaded onto the exposed thread at the lower end of the lower connecting screw 13, thus achieving the installation and positioning of the rubber rod 8 and the lower connecting screw 13.

[0041] Preferably, two first locking nuts 14 can be installed at the lower end of the lower connecting screw 13 to achieve a double limiting effect. The function of the first locking nuts 14 is to restrict the rubber rod 8 to be installed on the lower connecting screw 13. The upper end of the lower connecting screw 13 is not locked, so when the concrete is conveyed and vibration occurs, the lower connecting screw 13 can drive the rubber rod 8 to vibrate, realizing the swing vibration of the rubber rod 8.

[0042] like Figure 6 As shown, the protective structure includes a vibratory rod outer tube 6, which consists of an upper tube and a lower tube. The upper end of the upper tube is welded to a steel plate 51 for fixation. A threaded hole is provided inside the lower end of the upper tube, and an external thread is provided at the upper end of the lower tube. The external thread matches the threaded hole, facilitating the installation and disassembly of the upper and lower tubes and enabling maintenance of the vibration structure located inside the vibratory rod outer tube 6. During installation, after the vibration structure is installed, the lower tube is finally threaded onto the upper tube.

[0043] like Figure 9 As shown, the outer tube 6 of the vibrator surrounds the vibrating structure, mainly serving a protective function.

[0044] Preferably, the trumpet section 42 is made of thin-walled steel pipe, and the isolation pipe 5 is a conical structure with the tip pointing upwards and the opening downwards. The diameter of the trumpet section 42 gradually increases downwards from the connection point with the connecting section 41. Combined with the isolation pipe 5 placed inside the trumpet section 4, this ensures that the concrete fed from the mixing pipe 1 into the trumpet section 4 is distributed more evenly in the circumferential direction as it moves downwards. Then, under the vibration of the vibrating rod assembly, air inside the concrete is eliminated, making the concrete more compact, thereby achieving the effect of evenly vibrating and spreading the concrete delivered to the pouring position. Furthermore, the structure of the trumpet section 42 and the isolation pipe 5 also prevents concrete from clogging in one place, accelerating the construction speed.

[0045] like Figure 2 and Figure 3As shown, in order to facilitate the disassembly and installation of this utility model, the connecting section 41 is fixed to the mixing pipe 1 by a connecting structure. Therefore, during disassembly, the connecting structure can be directly operated, making the installation and removal simple and easy to operate. Specifically, the connecting structure mainly consists of: a rotating cap 9, a movable piece 10, a pair of upper connecting screws 11, and a pair of second locking nuts 12. The rotating cap 9 mainly consists of a pair of arc-shaped rotating pieces 91 and a hinge 94. The hinge 94 is connected to one end of the pair of rotating pieces 91 to achieve the hinge connection of the pair of rotating pieces 91. The other end of the pair of rotating pieces 91 is integrally machined with a flange 92. Both flanges 92 are provided with a vertically penetrating insertion hole 93 and an opening 922 that can accommodate the movable piece 10. The opening 922 is located in the middle of the flange 92. The movable piece 10 is provided with two mutually spaced through holes 101. The upper and lower ends of the through holes 101 are connected to the insertion holes 93 to facilitate the passage of the upper connecting screws 11. The lower end of the upper connecting screws 11 can pass through the corresponding insertion holes 93 and through holes 101. The second locking nuts 12 are threadedly connected to the lower end of the corresponding upper connecting screws 11 to limit the movement of the movable piece 10.

[0046] A pair of rotating plates 91 can be assembled into a hollow circular structure. During installation, the pair of rotating plates 91 are opened so that the connection between the connecting section 41 and the mixing pipe 1 is located inside the hollow. Then, the pair of rotating plates 91 are closed so that the rotating cap 9 completely surrounds the outer periphery of the connection between the connecting section 41 and the mixing pipe 1. Next, the movable plate 10 is horizontally inserted between the two openings 922. Then, the two T-shaped upper connecting screws 11 are inserted into the corresponding insertion holes 93 and through holes 101, respectively. Finally, the second locking nut 12 is locked to the lower end of the upper connecting screw 11, thus achieving a secure installation of the conveying pipe 4 and the mixing pipe 1. This method is not only simple to operate, but also has a simple connection structure and is easy to process, making it suitable for long-term promotion and use.

[0047] In summary, this invention, through the coordinated operation of the conveying pipe 4, the separator, and the vibrator assembly, achieves the effect of simultaneous pouring and vibration to reach the pouring position in one go. The vibration of the mixing pipe driving the vibrator assembly ensures more uniform concrete spreading and ensures that the concrete reaches the pouring position in one go, thus preventing cracking caused by loose joints at the junctions of multiple pours. Furthermore, this invention has a simple structure, is easy to install, and can be installed and operated on-site, shortening the construction period. It eliminates the need for manual vibration and addresses the issue of loose joints at the junctions of multiple pours, reducing vibrator noise. Therefore, it is convenient and reliable to use.
