Abstract
Description
Technical Field
[0001] The utility model relates to a folding arm assembly for pumping silt solidified soil into a seabed. Background Art
[0002] Setting up artificial structures such as piles on the seabed will destroy the scouring and silting balance of the original seabed. The water flow around the piles becomes turbulent and chaotic, and even forms vortices, which corrode the seabed around the piles and seriously endanger the safety and stability of offshore structures. Therefore, it is crucial to take anti-scouring protection measures.
[0003] Our company applies silt solidification technology to the anti-scour protection of offshore pile foundations, mainly using marine silt resources for chemical solidification, and then directly blowing the ultra-high water content silt solidified soil to the seabed surface around the pile foundation. Relying on the self-flowing property of the high-water content solidified soil slurry, it flows autonomously to the area to be protected, and can fill the scour pits under different working conditions around the pile foundation. The ultra-high water content silt solidified soil slurry gradually changes from liquid to a solid and continuous state that resists scour. Its strength gradually increases with the development of the coagulation process, and finally forms a whole plate-shaped silt solidified soil bottom protection structure around the pile. In order to enable the solidified soil to be more accurately pumped to the pumping point, our company has developed a folding arm assembly for use with the pumping pipe to achieve stable pumping of the hose under the sea.

[0022] The utility model is further described below in conjunction with the accompanying drawings.
[0023] like Figures 1 to 5 The utility model discloses a folding arm assembly for pumping silt solidified soil into a seabed, comprising a turntable 1, a folding arm 2 and a support frame 3.
[0024] The turntable 1 is an electric turntable, including a motor, a reduction box and a mounting seat 11. The motor is connected to the input end of the reduction box, and the mounting seat 11 is connected to the output end of the reduction box. The mounting seat 11 forms the rotating free end of the turntable 1 and can rotate 360 degrees. To facilitate the movement of the entire assembly, the reduction box and the motor can be fixed on a movable bracket (the bracket is provided with a fixed support foot).
[0025] The folding arm 2 includes a lever arm 21, a cylinder 22 and a hinged rod 23. The lever arm 21 is provided with a plurality of lever arms 21. Adjacent lever arms 21 are hinged to each other. A rotating joint is formed between two lever arms 21. Each rotating joint is driven by a cylinder 22. The cylinder 22 is hinged to the corresponding lever arm 21 (such as Figure 2 As shown in the figure, in order to facilitate the installation of the cylinder, a hinge ear for installing the cylinder 22 is provided on the corresponding lever arm 21. Two hinged rods 23 are hinged on the cylinder axis of each cylinder, and the two hinged rods 23 share the same hinge point on the cylinder axis. The other ends of the two hinged rods 23 are respectively hinged on the two lever arms 21 of the corresponding rotating joint. After the folding arm 2 is folded, all the lever arms are parallel to each other.
[0026] A cylinder 22 and an articulated rod 23 are hinged on the mounting seat 11 , and the cylinder shaft of the cylinder 22 and the articulated rod 23 are both hinged to the lever arm 21 at the end of the folding arm 2 .
[0027] After the folding arm 2 is folded, in order to better support the folding arm 2 , a support frame 3 is provided on one side of the turntable 1 , which is used to support the folded folding arm 2 .
[0028] The support frame 3 includes a triangular support leg 31 and a V-shaped support seat 32. The V-shaped support seat 32 is fixed on the triangular support leg 31. The folded folding arm 2 is supported in the V-groove of the V-shaped support seat 32. In order to avoid rigid contact between the folding arm 2 and the support frame 3, a rubber pad 33 is provided in the V-groove of the V-shaped support seat 32.
[0029] The folding arm 2 in the utility model occupies a small space after being folded. When in use, the hose is tied to the folding arm 2.
