Description

Technical Field

[0001] This invention relates to the field of construction drones, and more particularly to a tool for pouring reinforced concrete structures and its method of use. Background Technology

[0002] Concrete pouring is the core construction process of pouring well-mixed concrete mixture into a pre-set template and shaping it through processes such as transportation, placement, and vibration.

[0003] Concrete pouring must strictly follow the three-step process of "preparation-pouring-curing", each step of which directly affects the final strength and quality.

[0004] (1) Preparations before pouring: Check the template: Ensure the template is stable, the joints are tight, the dimensions meet the design requirements, and the surface is coated with a release agent.

[0005] Treatment of the base layer: Clean the surface of the reinforcing bars or subbase, removing debris and oil stains, and moisten with water if necessary (but there should be no standing water).

[0006] Equipment commissioning: Confirm that the concrete pump, vibrator and other equipment are operating normally, and prepare emergency backup equipment.

[0007] (2) Control during pouring: Layered pouring: The concrete is poured in layers according to the structural height and the initial setting time of the concrete. The thickness of each layer is usually no more than 30-50cm to prevent segregation.

[0008] Compacting: Use an immersion vibrator, inserting it quickly and pulling it out slowly, until there are no air bubbles on the surface and cement slurry appears. Avoid over-vibration or under-vibration.

[0009] Continuous operation: Try to ensure that the pouring is continuous. If it is necessary to interrupt, the interval should be shorter than the initial setting time of the concrete (usually 1-2 hours, depending on the mix proportion).

[0010] (3) Post-pouring curing: Cover and retain moisture: Within 12 hours after pouring, cover with burlap sacks, geotextile or plastic film to prevent moisture from evaporating too quickly.

[0011] Water curing: The curing period for ordinary concrete shall not be less than 7 days, and for impermeable or high-strength concrete, not less than 14 days, keeping the surface continuously moist.

[0012] Currently, traditional concrete pouring methods require workers to operate the discharge end of the pouring pipe. This method poses safety hazards, and in some areas, it is inconvenient to erect construction platforms for workers to walk on. Therefore, the use of drones for pouring concrete is beginning to be applied in the construction field. For example, patent application number 202322032466.7 discloses a concrete pouring device, belonging to the field of engineering construction technology. It includes a feeding pipe, a drone, an extension pipe, a unwinding device, and a fixing device. The feeding pipe is mounted on the drone's body. One end of the extension pipe is connected to one end of the feeding pipe, and the other end of the extension pipe is used to extend into the pouring chamber to pour concrete. The other end of the feeding pipe is used to receive concrete output from a concrete pump truck. The unwinding device is used to release or rewind the feeding pipe, and the fixing device is used to fix the feeding pipe to the drone's body. This utility model enables safe and convenient concrete pouring construction in sewage treatment plant construction.

[0013] However, existing drones used for concrete pouring still require workers to vibrate the poured concrete after the pouring is completed, making it impossible to achieve fully unmanned operation. Summary of the Invention

[0029] like Figure 1-6As shown, a rigid concrete structure pouring tool includes a large drone. A dual-axis motor 7 is installed at the end of the drone's arm. A propeller 9 is installed on the power output shaft at the top of the dual-axis motor 7, and a vibrating mechanism is installed on the power output shaft at the bottom of the dual-axis motor 7. A connecting pipe 5 is installed through the drone's body 6, and is fixedly connected to the drone. The bottom end of the connecting pipe 5 is threadedly connected to the end of a concrete guide hose. A concrete transfer chamber 3 is installed at the top of the connecting pipe 5, and is fixedly connected to and communicates with the concrete transfer chamber 3. The concrete transfer chamber 3 is located above the drone. Concrete output pipes 4 are installed on both sides of the drone's body 6, and are fixedly connected at the top and bottom of the concrete transfer chamber 3.

[0030] The concrete guide hose is connected to the concrete pump truck. After the large drone flies over the area to be poured, the concrete pump truck inputs the concrete into the concrete transfer chamber 3 through the concrete guide hose and connecting pipe 5, and then sprays it out to the area to be poured through the concrete output pipe 4, realizing unmanned concrete pouring. Example 2

[0031] like Figure 1-6 As shown, while other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the vibration mechanism includes a drive shaft 8, the top of the drive shaft 8 is fixedly connected to the power output shaft at the bottom of the dual-axis motor 7, a connecting plate 10 is provided at the bottom of the drive shaft 8, the drive shaft 8 is fixedly connected to the connecting plate 10, a plurality of connecting rods 11 are provided below the connecting plate 10, the upper end of the connecting rod 11 is fixedly connected to the connecting plate 10, and a vibration component is installed at the lower end of the connecting rod 11.

[0032] The vibration assembly includes an upper vibration pipe 13, the top end of which is fixedly connected to a connecting rod 11. The upper vibration pipe 13 is sleeved on a vibration rod 17, and a bearing 12 is sleeved on the top end of the vibration rod 17. The inner ring of the bearing 12 is fixedly connected to the vibration rod 17, and the outer ring of the bearing 12 is fixedly connected to the top end of the upper vibration pipe 13. A middle vibration pipe 16 is arranged below the upper vibration pipe 13 and is sleeved on the vibration rod 17. The top surface of the middle vibration pipe 16 has multiple hemispherical grooves 15, and a sphere 14 is arranged in each of the hemispherical grooves 15. The sphere 14 is located between the upper vibration pipe 13 and the middle vibration pipe 16, and the top of the sphere 14 is fixedly connected to the bottom of a support column 23. The upper end is fixedly connected to the bottom end of the upper vibrating pipe 13; multiple lower vibrating pipes 18 are sleeved on the vibrating rod 17, and the lower vibrating pipes 18 are all located below the middle vibrating pipe 16. Springs 19 are fixedly installed on both the upper and lower sides of the lower vibrating pipes 18. The springs 19 are sleeved on the vibrating rod 17. The springs 19 at the top are fixedly connected to the middle vibrating pipe 16, and the springs 19 at the bottom are fixedly connected to the limiting plate 20. The limiting plate 20 is located at the bottom of the vibrating rod 17 and is fixedly connected to the vibrating rod 17. A guide rail 22 is fixedly installed on the side of the vibrating rod 17. The guide rail 22 passes through the middle vibrating pipe 16 and the lower vibrating pipes 18. A cone 21 is provided at the bottom of the limiting plate 20 and is fixedly connected to the limiting plate 20.

[0033] After the concrete pouring is completed, remove the concrete guide hose and fly the large drone over the pouring area again, so that the lower vibrating pipe 18 and the middle vibrating pipe 16 on the large drone can be inserted into the concrete.

[0034] The dual-axis motor 7 on the large drone drives the propeller 9 to rotate, and at the same time drives the upper vibrating pipe 13 to rotate synchronously through the transmission shaft 8, connecting plate 10, and connecting rod 11. The rotation of the dual-axis motor 7 and the upper vibrating pipe 13 is always synchronized.

[0035] The upper vibrating pipe 13 drives the middle vibrating pipe 16 to rotate through the support column 23 and the ball 14. The middle vibrating pipe 16 drives the lower vibrating pipe 18 to rotate through the vibrating rod 17 and the guide rail 22. The rotation of the middle vibrating pipe 16 and the lower vibrating pipe 18 is always synchronized.

[0036] As the lower vibrating pipe 18 and the middle vibrating pipe 16 are inserted into the concrete, the rotation speed of the middle vibrating pipe 16 is lower than that of the upper vibrating pipe 13 due to the resistance of the concrete. This allows the ball 14 to continuously detach from the hemispherical groove 15 and move to the adjacent hemispherical groove 15. During this process, the ball 14 continuously strikes the middle vibrating pipe 16, causing the middle vibrating pipe 16, the lower vibrating pipe 18, and the vibrating rod 17 to vibrate synchronously to compact the concrete.

[0037] During this process, the sphere 14 drives the middle vibrating pipe 16 to move up and down repeatedly, and the middle vibrating pipe 16 drives the spring 19 to compress and extend repeatedly, so that the spring 19 stirs the concrete and further vibrates it. Example 3

[0038] like Figure 1-6 As shown, while other parts are the same as in Example 2, the difference between this example and Example 2 is that: a sealing cover 2 is provided on the top of the concrete transfer silo 3, the concrete transfer silo 3 is threadedly connected to the sealing cover 2, and a handle 1 is provided on the top of the sealing cover 2, and the handle 1 is fixedly connected to the sealing cover 2.

[0039] By removing the sealing cap 2, the concrete transfer chamber 3 and the concrete output pipe 4 can be cleaned to prevent residual concrete.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
