Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a concrete pump output head suitable for filling gaps in secondary structure infill walls. Background Technology

[0002] The primary function of secondary structural infill walls is to partition space, dividing large spaces into smaller ones according to the building's functional requirements. They also provide some sound insulation, reducing noise interference between different spaces. Furthermore, infill walls offer some thermal insulation, helping to improve the building's thermal environment. Although they do not bear the main structural load of the building, they play a crucial supplementary and beneficial role in enhancing the building's functionality and performance. To ensure construction quality, appropriate equipment is required for grouting during the construction of secondary structural infill walls.

[0003] As disclosed in authorization announcement number CN221856302U, a concrete pump output head suitable for filling gaps in secondary structure infill walls is provided. It includes a connecting pipe, one end of which is connected to the discharge pipe of the concrete pump, and the other end is connected to a nozzle. The nozzle is V-shaped and includes a top plate and a bottom plate. The top plate is fixedly connected to the upper part of the connecting pipe, and the bottom plate is hinged to the lower part of the connecting pipe. An elastic connecting plate is provided between the top plate and the bottom plate. It can adapt to gaps of different heights, perfectly filling gaps in a single operation; it is simple to operate, reduces the workload of construction workers, and improves project quality.

[0004] However, during use, the rotating cylinder of this utility model is difficult to adapt to uneven wall surfaces, which can easily cause the rotating cylinder to be partially suspended, resulting in the nozzle tilting left and right, accelerating the wear rate of the nozzle, and making it difficult to ensure the construction stability of concrete filling operations. To address this, we have proposed a concrete pump output head suitable for filling gaps in secondary structure infill walls, which solves the problem of this utility model's inability to adapt to uneven wall surfaces and its poor operational stability, thus improving the practical effect of this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a concrete pump output head suitable for filling gaps in secondary structure infill walls, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A concrete pump output head suitable for filling gaps in secondary structure infill walls includes a base plate, a moving mechanism on one side of the base plate, and an auxiliary connecting mechanism on the other side of the base plate.

[0008] Preferably, the moving mechanism includes a fixed plate, which is fixedly welded to a base plate. A T-shaped connecting plate is fixedly installed on one side of the fixed plate. An axle is rotatably connected to the end of the T-shaped connecting plate. A movable wheel is movably installed at one end of the axle. A spring washer is fixedly provided on one side of the axle. U-shaped blocks are fixedly provided on both sides of the base plate. A thickened spring is connected between the spring washer and the U-shaped block. The fixed plate has an installation groove. The T-shaped connecting plate has four threaded through holes, which correspond one-to-one with the installation groove. Installation bolts are provided in the threaded holes and the installation grooves. The T-shaped connecting plate has a connecting hole. A connecting clamp is fixedly provided at one end of the axle near the T-shaped connecting plate. The connecting clamp has a through hole corresponding to the connecting hole. A connecting pin is provided in the connecting hole and the through hole.

[0009] By adopting the above technical solution: the T-shaped connecting plate is fixedly installed on the fixed plate by mounting bolts, the wheel axle is rotatably connected to the T-shaped connecting plate by connecting pins, and the thickened spring connected between the spring washer and the U-shaped block provides elastic support for the moving wheel.

[0010] Preferably, the auxiliary connecting mechanism includes a horizontal plate, which is perpendicularly connected to the base plate. A positioning block is fixedly installed at the top of the horizontal plate, and a connecting tube passes through the positioning block. A spray head is connected to the end of the connecting tube near the base plate, and an internal thread is provided at the end of the connecting tube away from the base plate. A tightening bolt is threaded to the top of the positioning block. A U-shaped groove is provided on the top surface of the horizontal plate, and the U-shaped groove fits into the bottom end of the spray head. Handle rods are fixedly installed on both sides of the horizontal plate, and foam handle sleeves are fitted on the outside of the handle rods.

[0011] By adopting the above technical solution: the spray head and connecting pipe are installed on the top of the horizontal plate through the positioning block and the U-shaped slot on the top surface of the horizontal plate, and the tightening bolt is rotated so that the bottom end of the tightening bolt is pressed against the connecting pipe. At the same time, the bottom end of the spray head is embedded in the U-shaped slot to prevent the spray head from tilting to the left or right and improve the stability of use. The end of the connecting pipe is connected to the external concrete delivery pipe through the internal thread set at one end. The handle and foam handle cover make it convenient for construction personnel to hold the concrete pump output head for construction operations.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This concrete pump output head, suitable for filling gaps in secondary structure infill walls, utilizes a moving mechanism with a fixed plate, T-shaped connecting plate, wheel axle, spring washer, U-shaped block, and thickened spring. During movement, the compressibility and automatic reset properties of the thickened spring allow each moving wheel to adapt to the undulations of the wall surface without affecting the contact between other moving wheels and the ground. This prevents the moving wheels from being suspended in the air, which could cause excessive tilting of the spray head and damage, thus improving the stability and durability of the output head.

[0014] 2. This concrete pump output head, suitable for filling gaps in secondary structure infill walls, uses a positioning block and a U-shaped slot on the top surface of the horizontal plate to install the spray head and connecting pipe to the top of the horizontal plate. By rotating the tightening bolt, the bottom end of the tightening bolt is pressed against the connecting pipe. At the same time, the bottom end of the spray head is embedded in the U-shaped slot to prevent the spray head from tilting to the left or right, further improving the stability of the output head.

[0020] 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.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A concrete pump output head suitable for filling gaps in secondary structure infill walls includes a base plate 1, a moving mechanism on one side of the base plate 1, and an auxiliary connecting mechanism on the other side of the base plate 1.

[0023] In this embodiment, preferably, the moving mechanism includes a fixed plate 2, which is fixedly welded to the base plate 1. A T-shaped connecting plate 3 is fixedly installed on one side of the fixed plate 2. A wheel axle 4 is rotatably connected to the end of the T-shaped connecting plate 3. A movable wheel 5 is movably installed on one end of the wheel axle 4. A spring washer 6 is fixedly provided on one side of the wheel axle 4. U-shaped blocks 7 are fixedly provided on both sides of the base plate 1. A thickened spring 8 is connected between the spring washer 6 and the U-shaped blocks 7. The fixed plate 2 has an installation groove 201. The T-shaped connecting plate 3 has four threaded through holes 301, which correspond one-to-one with the installation groove 201. Installation bolts 302 are provided in the threaded holes and the installation groove 201. The T-shaped connecting plate 3 has a connecting hole 303. A connecting clamp 401 is fixedly provided on one end of the wheel axle 4 near the T-shaped connecting plate 3. The connecting clamp 401 has a through hole corresponding to the connecting hole 303. A connecting pin 402 is provided in the connecting hole 303 and the through hole.

[0024] The above solution involves fixing the T-shaped connecting plate 3 to the fixed plate 2 using mounting bolts 302, rotatably connecting the wheel axle 4 to the T-shaped connecting plate 3 using connecting pins 402, and providing elastic support for the moving wheels 5 through the thickened spring 8 connecting the spring washer 6 and the U-shaped block 7. This allows each moving wheel 5 to adapt to the undulations of the wall surface without affecting the contact between other moving wheels 5 and the ground, preventing the moving wheels 5 from being suspended and causing the spray head 12 to tilt too much and be damaged, thus improving the stability of the output head.

[0025] In this embodiment, preferably, the auxiliary connecting mechanism includes a horizontal plate 9, which is vertically connected to the base plate 1. A positioning block 10 is fixedly installed at the top of the horizontal plate 9. A connecting pipe 11 passes through the inside of the positioning block 10. A spray head 12 is connected to the end of the connecting pipe 11 near the base plate 1. An internal thread is provided at the end of the connecting pipe 11 away from the base plate 1. A tightening bolt 13 is threadedly connected to the top of the positioning block 10. A U-shaped groove 901 is opened on the top surface of the horizontal plate 9. The U-shaped groove 901 fits into the bottom end of the spray head 12. Handle rods 14 are fixedly installed on both sides of the horizontal plate 9. A foam handle sleeve 15 is sleeved on the outside of the handle rod 14.

[0026] The above solution involves using the U-shaped slot 901 on the top surface of the positioning block 10 and the horizontal plate 9 to install the spray head 12 and the connecting pipe 11 to the top of the horizontal plate 9. The tightening bolt 13 is then rotated to tighten the connecting pipe 11 at its bottom end. Simultaneously, the bottom end of the spray head 12 is embedded in the U-shaped slot 901 to prevent it from tilting left or right, thus improving stability. The connecting pipe 11 is connected to an external concrete delivery pipe via an internal thread. The handle 14 and foam grip 15 facilitate hand-holding of the concrete pump output head for construction work, ensuring comfort and reducing worker fatigue, thereby improving work efficiency.

[0027] In this embodiment, the concrete pump output head for filling gaps in secondary structure infill walls is used by first installing the spray head 12 and connecting pipe 11 onto the top of the horizontal plate 9 via the U-shaped slot 901 on the top surface of the positioning block 10 and the horizontal plate 9. Then, the tightening bolt 13 is rotated so that the bottom end of the tightening bolt 13 presses against the connecting pipe 11. Simultaneously, the bottom end of the spray head 12 is embedded inside the U-shaped slot 901 to prevent the spray head 12 from tilting left or right, improving stability during use. Then, the end of the connecting pipe 11 is connected to the external concrete delivery pipe via the internal thread on one end of the connecting pipe 11. During use, the construction worker holds the handle 14 with both hands, inserts the spray head 12 into the wall gap, and moves the movable wheels 5 along the wall surface. During concrete filling, the worker can walk along the gap to move the spray head 12. Because a thickened spring 8 connects the spring washer 6 and the U-shaped block 7, and the wheel axle 4 is rotatably connected to the T-shaped connecting plate 3, each movable wheel 5 can adapt to the undulations of the wall surface without affecting the contact between other movable wheels 5 and the ground. This prevents the spray head 12 from tilting excessively due to the movable wheels 5 being suspended in the air, thus improving the stability and durability of the output head. The foam sleeve on the handle 14 increases the friction between the hand and the handle 14, ensuring user comfort, reducing worker fatigue, and thus improving work efficiency.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
