Pile holding device for monitoring perpendicularity of pile body through angle change of telescopic arm and operation method of pile holding device

Abstract

The invention discloses a pile holding device for monitoring the perpendicularity of a pile body through the angle change of a telescopic arm and an operation method of the pile holding device. An angle sensor is arranged on a pile holding tentacle and can accurately measure whether the pile body inclines or not in the pile sinking process. The connecting manner of a hydraulic pipe support and a connecting beam is improved, the problem that a telescopic arm of a traditional pile holding frame can only work horizontally is solved, the telescopic arm can rotate within a certain angle range, and therefore the telescopic arm can keep perpendicular to the pile body for centering work. The pile holding tentacle at the tail end of the telescopic arm is improved, a single tentacle is improved into double tentacles, a pile holding pile pad is arranged, and the work load of the pile holding device during deviation rectifying work is reduced. The angle sensor is arranged on the hydraulic pipe support, due to the fact that the telescopic arm keeps perpendicular to the pile body all the time when stretching out to hold a pipe pile, when the pipe pile inclines, the angle of the hydraulic pipe support can rotate along with the pipe pile, the inclination state of the pile body can be rapidly reflected through the angle sensor, and the work complexity is reduced.

Description

technical field [0001] The invention belongs to the field of offshore wind power pile foundation installation, and in particular relates to a pile holder for monitoring the verticality of a pile body through the angle change of a telescopic arm and an operation method thereof. Background technique [0002] In offshore wind power projects, wind turbine pile foundations need to be installed, mainly including monopile foundations, transition piles, and wind turbine towers installed on monopile foundations. When installing the pile foundation, the single pile foundation is usually penetrated into the seabed by a piling hammer. However, the offshore operation is different from the onshore project. During the offshore piling operation, it is easily affected by variable factors such as high winds, waves, ocean currents and tides. In addition, the seabed geological conditions are poor, and the seabed soil is generally soft, so the single-pile foundation is prone to inclination durin...

AI Technical Summary

Problems solved by technology

[0004] But there are following problems in existing pile-holding device equipment: the telescopic arm on the existing pile-holding device has only independent uprighting tentacles and can only be stretched horizontally to right up the inclination of pile body, so that the whole structure needs greater strength, thus increasing Increased the workload of the pile holder

At the same time, the existing pile holder is not easy to monitor the inclination of the pile body, which increases the complexity of the work
