Description

Technical Field

[0001] This utility model relates to the technical field of concrete pouring devices, and in particular to a concrete pouring construction device for fishway engineering. Background Technology

[0002] The construction of hydraulic structures such as dams and sluices causes longitudinal and lateral changes in river habitats, resulting in a qualitative change in the habitat conditions of aquatic animals such as fish in a short period of time. However, fish are very sensitive to changes in their habitat environment and find it difficult to adapt to these changes in hydrological conditions in a short period of time. This inevitably leads to a reduction in the range of fish habitats and a significant decrease in hydrological diversity and richness. At present, the impact of river ecological protection, especially the impact of dam construction on fish, has received high attention. Efforts are being made to develop ecological compensation technologies such as fishways, which have epoch-making practical significance for protecting fish resources in hydropower projects and promoting the development of ecohydraulics. European and American countries have tried to use thin-walled concrete structures (thickness 0.4-0.6m) in fishway projects. For example, the Fraser River fishway in Canada uses a prefabricated U-shaped channel structure (thickness 0.5m) combined with self-compacting concrete technology, which improves construction efficiency by more than 30%.

[0003] In China, the thickness of concrete sidewalls in fishways is generally ≥0.8m (such as the fishway in the Three Gorges Project), with a steel reinforcement content as high as 120kg / m. 3 This leads to material waste and extended construction periods. To improve construction efficiency, some fishways adopt prefabricated structures, using prefabricated components for on-site assembly. For example, Chinese Patent Publication No. CN215518657U discloses "a fishway" that uses prefabricated components for on-site assembly. Prefabricated components can achieve rapid, mass, and mechanized production, thus avoiding the constraints of on-site construction conditions, significantly improving construction efficiency, ensuring construction quality, and saving a lot of manpower and material resources.

[0004] However, in actual production, since fish passages are mostly U-shaped, specific molds are required for shaping during casting. The process of assembling the molds after casting requires manual labor, which is labor-intensive and inefficient. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for specific mold combinations for shaping during fishway construction, the requirement for manual assembly, high labor intensity, and low efficiency. Therefore, this invention proposes a concrete pouring construction device for fishway engineering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a concrete pouring construction device for fishway engineering, including a conveyor platform, on which multiple containers are placed, a pouring mechanism is set on the conveyor platform, the pouring mechanism is connected to a material supply pipe, a feeding rack is set on one side of the pouring mechanism, a feeding platform is set below the feeding rack, a mold that cooperates with the containers is placed on the feeding platform, a guide rail is fixedly set on the feeding rack, a moving platform is slidably set on the guide rail, and a material picking component is set at the lower end of the moving platform.

[0008] Furthermore, the material handling assembly includes a cylinder fixedly mounted on the moving platform, the output shaft of which passes through the moving platform and is fixedly connected to a material handling plate.

[0009] Furthermore, an electromagnet is fixedly installed on the material picking plate, and a guide rod is fixedly installed at the upper end of the material picking plate, the guide rod being movably connected to the moving table.

[0010] Furthermore, a motor is provided on one side of the feeding rack, and the output shaft of the motor is fixedly provided with a lead screw that is rotatably connected to the feeding rack. The lead screw is threadedly connected to the moving table.

[0011] Furthermore, the pouring mechanism includes a support frame, on which a lifting frame is provided, and on which a pouring pipe is provided.

[0012] Furthermore, the mold is provided with a connecting part corresponding to the material taking component, and a limiting plate that cooperates with the container is fixedly provided at the upper end of the connecting part.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A concrete pouring construction device for fishway engineering includes a conveyor platform 1, on which multiple containers 2 are placed. A pouring mechanism 3 is installed on the conveyor platform 1. The pouring mechanism 3 is connected to a material supply pipe. A feeding rack 4 is installed on one side of the pouring mechanism 3. A feeding platform 5 is installed below the feeding rack 4. A mold 6 that cooperates with the containers 2 is placed on the feeding platform 5. A guide rail is fixedly installed on the feeding rack 4. A moving platform 7 is slidably installed on the guide rail. A material picking component 8 is installed at the lower end of the moving platform 7.

[0023] In this utility model, the container 2 is conveyed by the conveyor table 1, and concrete is poured into the container 2 by the pouring mechanism 3. The mold 6 is placed in the container 2 and combined with the material loading rack 4 and the material unloading component 8 to shape the concrete, resulting in higher pouring efficiency.

[0024] Furthermore, in this embodiment, the material handling component 8 includes a cylinder 81 fixedly mounted on the moving platform 7. The output shaft of the cylinder 81 passes through the moving platform 7 and is fixedly connected to the material handling plate 82. The cylinder 81 controls the lifting and lowering of the material handling plate 82. When placing the mold 6, pressure can also be applied to the mold 6 to change the shape of the concrete in the container 2.

[0025] Furthermore, in this embodiment, an electromagnet 83 is fixedly installed on the material picking plate 82, and a guide rod 84 is fixedly installed at the upper end of the material picking plate 82. The guide rod 84 is movably connected to the moving table 7. The electromagnet 83 picks up the mold 6, thereby moving the mold 6 for transportation.

[0026] It should be noted that, in this embodiment, a motor 41 is provided on one side of the feeding rack 4, and a lead screw 42 is fixedly provided on the output shaft of the motor 41 and rotatably connected to the feeding rack 4. The lead screw 42 is threadedly connected to the moving table 7. The motor 41 drives the lead screw 42 to rotate, thereby moving the moving table 7 to change position. As the moving table 7 moves, the material picking component 8 and the mold 6 move accordingly.

[0027] Furthermore, in this embodiment, the pouring mechanism 3 includes a support frame 31, a lifting frame 32 is provided on the support frame 31, a pouring pipe 33 is provided on the lifting frame 32, and a cylinder is provided between the support frame 31 and the lifting frame 32. The lifting frame 32 is raised and lowered by the cylinder, thereby inserting the pouring pipe 33 into the container 2.

[0028] More specifically, in this embodiment, the mold 6 is provided with a connecting part 61 corresponding to the material taking component 8. The upper end of the connecting part 61 is fixedly provided with a limiting plate 62 that cooperates with the container 2. The limiting plate 62 is made of magnetic metal and can be attracted by an electromagnet. When the mold 6 is placed in the container 2, the limiting plate 62 supports the mold 6 at the point where it contacts the container 2, thereby ensuring that there is space for shaping concrete between the mold 6 and the container 2.

[0029] Working method: During operation, container 2 is conveyed by conveyor table 1, concrete is poured into container 2 by pouring mechanism 3, mold 6 is picked up by electromagnet 83, lifting and lowering of material picking plate 82 is controlled by cylinder 81, and screw 42 is driven to rotate by motor 41, which drives moving table 7 to move and change position. As moving table 7 moves, material picking component 8 and mold 6 move accordingly, transporting mold 6 to the top of container 2 and then placing it inside container 2, thereby forming a combined mold.
