Abstract

The invention discloses a telescopic trestle system and a control method thereof, which are installed on a supporting platform or a supporting ship, and include a cylindrical body arranged on the supporting platform or supporting ship, and the cylindrical body is connected with a rotating shaft through a rotating mechanism. Chassis, the slewing chassis is provided with a hydraulic pump station and a cab, the slewing chassis is connected with a trestle fixed section, the hydraulic pump station is connected with the trestle fixed section through a luffing mechanism, and the front end of the trestle fixed section The trestle moving section is connected through a telescopic mechanism, and the front end of the trestle moving section is provided with an implantation device and an inclined ladder; it also includes a motion compensation control system, and the motion compensation control system includes a filter module and a controller module. The invention solves the problem of safe transportation of personnel under harsh sea conditions at sea, and can also provide transportation of electricity, water, oil and mud.

Description

technical field [0001] The present invention relates to trestle equipment, more specifically, to a telescopic trestle system and its control method, especially suitable for semi-submersible support platforms, offshore support ships, wind power operation and maintenance ships, marine traffic ships, pilot ships, rescue boat. Background technique [0002] With the rapid development of offshore wind power and oil exploration industries, personnel rotation and maintenance personnel disembark and disembark on offshore projects such as drilling platforms, FPSO, and wind power installations. Traditionally, cages, ship ramps, and helicopters are used to disembark and disembark. boat work. However, the problem of insufficient safety of the hanging cage is becoming more and more obvious. The ship ramp is subject to too many restrictions due to the influence of wind and waves, and the economy of the helicopter is too low. Contents of the invention [0003] In view of the above defec...
