Description

Technical Field

[0001] This application relates to the technical field of formwork concrete construction devices, and in particular to a construction device for underwater placement of formwork concrete. Background Technology

[0002] Currently, geotextile-filled concrete technology utilizes specially designed fabric geotextile bags as molds for concrete pouring. Concrete is injected into the geotextile bags using a high-pressure pump, and the constraint of the geotextile bags ensures the concrete is evenly distributed and solidifies within the bags. Geotextile-filled concrete is not only simple and efficient to construct, but also well-suited for complex terrains and special environments, such as underwater construction and slope protection.

[0003] Construction equipment for underwater placement of formwork concrete in related technologies generally includes a hull, ropes, and a suspended platform. Working principle: First, the formwork is transported to the designated location by the hull; then, the formwork and construction personnel are lowered off the ship using ropes and the suspended platform.

[0004] However, in existing technologies, the suspended platform sways quite violently during descent, which can easily cause construction workers to fall from the platform. Utility Model Content

[0005] This application provides a construction device for underwater placement of formwork concrete, which can reduce the possibility of large-scale swaying of the suspended platform during descent, and adopts the following technical solution:

[0006] A construction device for underwater placement of formwork concrete includes a hull, an installation frame mounted on the hull, a basket mounted on the installation frame, and a drive assembly mounted on the hull for driving the basket to move vertically; a guide rod is installed at the bottom of the installation frame, and a sliding sleeve is fixed to the side wall of the basket, the sliding sleeve being vertically slidably connected to the guide rod.

[0007] Preferably, a threaded rod is fixed to the top of the guide rod, and a threaded groove is provided at the bottom of the mounting bracket, with the threaded rod threadedly connected to the threaded groove.

[0008] Preferably, the drive assembly includes a winch mounted on top of the mounting frame, the winch comprising two coils of steel strand, each coil having an end detachably connected to the suspended platform away from the winch.

[0009] Preferably, a vertical rod is installed at the bottom of the suspended platform, a connecting ring is fixedly connected to the top of the vertical rod, and one end of the steel strand is detachably connected to the connecting ring through a connecting assembly.

[0010] Preferably, the connecting assembly includes a U-shaped connecting plate fixed to one end of the steel strand, the U-shaped connecting plate being sleeved on the connecting ring, and through holes and threaded holes respectively opened at both ends of the U-shaped connecting plate. A connecting screw is provided in the through hole, and one end of the connecting screw is threaded to the threaded hole.

[0011] Preferably, a plug rod is fixedly connected to the bottom of the vertical rod, and a plug hole is opened at the bottom of the suspended basket. The plug rod is inserted into the plug hole, and a support nut is threaded to the end of the plug rod away from the vertical rod.

[0012] In summary, this application has the following beneficial effects:

[0013] 1. The two guide rods and two sliding sleeves facilitate the guidance of the suspended platform, thereby reducing the possibility of large-scale swaying during descent; the drive assembly facilitates the downward movement of the suspended platform, thereby reducing the labor intensity of the operators.

It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0020] This application discloses a construction device for underwater placement of formwork concrete, such as... Figure 1 and Figure 2As shown, the system includes a hull 1, a mounting frame 2 installed on the deck of the hull 1, a basket 3 vertically slidably connected to the mounting frame 2, and a drive assembly installed on the hull 1 for driving the basket 3 to move vertically. Two guide rods 21 are vertically mounted on the bottom of the mounting frame 2, and sliding sleeves 31 are fixed to the side walls of the basket 3. The two sliding sleeves 31 are vertically slidably connected to the two guide rods 21. The two guide rods 21 and the two sliding sleeves 31 facilitate guiding the basket 3, thereby reducing the possibility of significant swaying during descent. The drive assembly facilitates driving the basket 3 downward, thereby reducing the workload of the operators.

[0021] like Figure 2 and Figure 3 As shown, a threaded rod 22 is fixedly connected to the top of each guide rod 21, and a threaded groove 23 is provided at the bottom of the mounting bracket 2. The threaded rod 22 is threadedly connected to the threaded groove 23. The threaded rod 22 and the threaded groove 23 facilitate the installation of the guide rod 21. A gripping part 24 is sleeved and fixedly connected to the top of the guide rod 21. The outer circumferential surface of the gripping part 24 is provided with anti-slip texture. The gripping part 24 facilitates the rotation of the guide rod 21.
