Angle-adjustable underwater anchor pile guide frame and operation method thereof

Abstract

The invention relates to an angle-adjustable underwater anchor pile guide frame and an operation method thereof. The angle-adjustable underwater anchor pile guide frame comprises a base, a guide mechanism, a first angle adjusting mechanism, a second angle adjusting mechanism, a hydraulic buffer mechanism and a driving mechanism, wherein the guide mechanism comprises a guide cylinder and is used for guiding pile inserting and piling in the anchor pile process; the first angle adjusting mechanism and the second angle adjusting mechanism are assembled on the base, are movably connected with the guide mechanism and are used for adjusting the angle of the guide mechanism; the first end of the hydraulic buffer mechanism is connected with the base, the second end of the hydraulic buffer mechanism is connected with the guide mechanism, and the hydraulic buffer mechanism is used for playing a buffer role when the guide mechanism performs angle adjustment; and the driving mechanism is used for driving the first angle adjusting mechanism, the second angle adjusting mechanism and the hydraulic buffer mechanism. According to the guide frame, an anchor pile can be always ensured to be vertically downward to perform installation operation through the angle adjusting mechanisms, the application range is large, the working hours can be shortened, the engineering cost can be reduced, and the potential operation risk can be eliminated.

Description

technical field [0001] The invention relates to an angle-adjustable underwater anchor pile guide frame and an operating method thereof, belonging to the technical field of offshore oil drilling. Background technique [0002] The pile insertion and piling operations during the installation of anchor piles need to be guided by the underwater independent pile guide frame placed on the seabed surface, but most seabeds are not flat, and the existing underwater independent pile guide frame has no angle adjustment Therefore, before the installation of anchor piles, it takes a lot of man-hours to conduct a large-scale site selection and comparison to determine the installation location, which increases the project cost, causes inconvenience to the installation of anchor piles, and also creates greater potential risks. Moreover, the existing underwater independent pile guide frame is only suitable for flat seabeds, and has a narrow range of action, which increases engineering costs, ...
