Description

Technical Field

[0001] The utility model relates to the field of lifting shackles, in particular to a deep-water lifting shackle. Background Art

[0002] At present, deep-water development requires the recovery of slings after a lot of underwater hoisting and installation, and shackles are required for hoisting. There are two types of shackles for underwater 200m. One is a hydraulic shackle combined with a hydraulic cylinder that uses surface hydraulic power connected to the shackle through a pipeline, and the installation and release are achieved through underwater control. However, the long hydraulic pipe is easily entangled with the hoisting tackle, affecting the construction. At the same time, the pin shaft controlled by the oil cylinder is easily disengaged, resulting in hoisting failure. Therefore, we need a shackle that can solve the release of deep-water hydraulic shackles and the recovery of shackles, with a compact structure and easy to inspect, which can be widely used in various deep-water underwater hoisting operations.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the present utility model with reference to the accompanying drawings.

[0020] Please refer to Figures 1 to 6 , the present utility model provides an embodiment:

[0021] Refer to Figure 1 and Figure 2, including a shackle body 1 with a U-shaped structure and a telescopic pin shaft 3. A connecting guide sleeve 2 is arranged on one side of the shackle body 1. The shackle body 1 is provided with two corresponding pin holes 4, and the pin holes 4 penetrate into the connecting guide sleeve 2. A pin guide groove 5 is arranged on the side wall of the connecting guide sleeve 2. On the other side of the shackle body 1 above the pin hole 4, an oil cylinder connecting sleeve 6 is arranged, and a locking oil cylinder 7 is arranged on the oil cylinder connecting sleeve 6. The telescopic pin shaft 3 penetrates through the connecting guide sleeve 2 and the pin hole 4 and is connected to the locking pin 8 of the locking oil cylinder 7.
