Embodiment 2

[0023] The difference from Example 1 is:

[0024] Such as image 3 , 4 As shown, when the payload of the operating type unmanned remote control submersible is large, the steel ring pick-and-place device of the present invention can be grasped by the underwater manipulator configured at its front to complete the steel ring pick-and-place work. At this time, the vertical motion mechanism adopts Remove the telescopic oil cylinder for the handle compatible with the manipulator clamp, and replace it with a handle suitable for the manipulator clamp to connect with the upper plate 2 (see figure 2 ). In this way, when the submersible moves to the vicinity of the wellhead and prepares to pick and place the steel ring, the underwater manipulator clamps the steel ring pick-and-place device, and the underwater manipulator stretches and pitches to complete the work of picking and placing the steel ring. Because the action of the underwater manipulator is more flexible and accurate than...

Abstract

The invention discloses a seal steel ring gripper for remote-operated vehicle comprising gripping jaws, spring compressing devices equipped between the gripping jaws, a spring compressed hydraulic cylinder equipped between the two spring compressing devices, and a vertical moving mechanism, an upper plate, a lower plate. Wherein, the gripping jaws have two types of fixed arc gripping jaw and moveable arc gripping jaw, the fixed arc gripping jaw is between the upper plate and the lower plate and connects to one of the plates and one end of the spring compressed hydraulic cylinder and the two spring compressing devices, the moveable arc gripping jaw connects to the other end of the spring compressed hydraulic cylinder and the two spring compressing devices, said fixed arc gripping jaw and moveable arc gripping jaw are provided with rubber rings, said vertical moving mechanism is equipped on the upper plate. The invention has a light weight, a simple structure, and can be used widely.

Description

technical field [0001] The invention relates to an underwater working tool, in particular to a pick-and-place device for a sealed steel ring for an unmanned remote control submersible. Background technique [0002] Since the mid-1970s, the application of unmanned remote control submersibles (underwater robots) in the offshore oil industry has developed rapidly, and unmanned remote control submersibles have gradually developed from observation to operation. The main tasks that the unmanned remote control submersible can complete on the offshore oil drilling platform are: hook with a cable, cut the steel cable, cable or hemp cable underwater, flush the mud covered by the wellhead or the level with a high-pressure water gun, and open or close the hydraulic connection The unmanned remote control submersible completes various specific underwater operations through its underwater manipulator and various special underwater tools. The sealing steel ring picker is an indispensable u...
