Abstract

The invention discloses a single-point mooring clamping jaw locking device which is characterized in that an installation base and a base are fixedly mounted on a base frame of an offshore platform, an arm supportis arranged between the installation base and the base, the installation base is connected with a mounting seat with a rotary driving function through a spherical bearing, a guide hole isformed in one end of the arm support, and a sleeve, a lead screw and a lead screw rotary driver are mounted; the other end of the arm support and a clamping jaw are simultaneously connected with thebase through spherical bearings, a telescopic driver and an arm support connecting rod are further installed in the middle of the arm support, a clamping jaw connecting rod is hinged to the connectingportion of the end, facing the base, of the clamping jaw, and the telescopic driver, the arm support connecting rod and the other end of the clamping jaw connecting rod are hinged. The telescopic driver drives the clamping jaw to rotate through the arm support connecting rod and the clamping jaw connecting rod to be clamped into a clamping groove of a mooring floating platform, then the driver isrotated to lock the arm support for a second time through the lead screw, and locking is conducted for the third time through the locking nut on the lead screw. The single-point mooring clamping jawlocking device is simple in structure, accurate and stable in locking effect and easy and convenient to operate.

Description

technical field [0001] The invention relates to ship auxiliary equipment, in particular to a claw-type locking device for single-point mooring. Background technique [0002] Offshore floating platforms (such as FPSO, FSO, FSRU, etc.) are one of the main modes of offshore oil development, and are widely used in oil and gas production, storage and export in various sea areas around the world. The mooring methods are mainly multi-point mooring and Single point mooring. The multi-point mooring offshore floating platform is suitable for the situation where the ocean environment is mild and the direction of the environmental load is relatively fixed, while the single-point mooring is on the sea to establish a fixed connection point, through a mechanical mechanism and a certain part of the offshore floating platform The connection enables the offshore floating platform to rotate around a single point with external loads. This single-point mooring adapted to the weathervane effect ...
