Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] The purpose of the present invention is to provide an overturning force detection device for a motion compensation platform base, which can be used for overturning force detection of an active motion compensation bridge crossing system or a slewing motion platform base of a marine crane, so as to avoid the danger of overturning in actual work. Can improve the security of the system.
[0017] An overturning force detection device for a motion compensation platform base can be used for overturning force detection of an active motion compensation bridge crossing system or a slewing platform base 1 of an ocean crane. The device specifically includes a lever mechanism 3 , an annular movable plate 4 and a pressure sensor 2 . The ring-shaped movable plate 4 will produce a small displacement after being subjected to the overturning force, and one end of the lever mecha...

The invention belongs to the field of offshore operations, and in particular relates to an overturning force detection device for a motion compensation platform base. The device consists of a slewing platform base, a pressure sensor, a lever mechanism, a ring-shaped movable plate, and a roller mechanism, and can be used for active motion compensation bridge crossing systems or pressure detection of the slewing platform base of marine cranes. The roller mechanism transmits the gravity and bending moment of the load on the upper platform to the base of the slewing platform with active motion compensation through a circular movable plate. One end of the lever mechanism is pressed against the circular movable plate, and the other end is pressed against the pressure sensor. , can detect the pressure of the motion compensation rotary platform base, avoid the danger of overturning in actual work, and improve the safety of the system. The invention is symmetrically distributed on the base of the rotary platform for active motion compensation. When used in an actual system, more than one can be installed in order to make the measured pressure and torque more accurate and reliable.
Description
technical field [0001] The invention belongs to the field of offshore operations, and in particular relates to an overturning force detection device for a motion compensation platform base. Background technique [0002] The traditional method of transfer of staff between the offshore operating platform and the ship is to directly dock the ship on the operating platform, and then transfer the staff. However, due to the influence of sea wind and waves and other factors, this method can only be carried out under low sea state conditions. In high sea state conditions, the transmission of staff or equipment is extremely dangerous. The generation of bridge technology and equipment has solved this problem well. [0003] The ship and the offshore operation platform are connected through a retractable gangway, so that the ship does not have to berth on the operation platform, and the danger of collision between the ship's swing and the operation platform is avoided. An active motio...
