Abstract

The invention discloses a method for monitoring the work attitude and safety of hoisting operation of a floating crane, comprising the following steps: acquiring initial data of floating crane attitude relative to a vertical reference coordinate system in real time; judging the hoisting operation work attitude of the floating crane; performing azimuth shift control on the floating crane; performing trim control on the floating crane; and performing heeling control on the floating crane. Real-time and accurate monitoring on the work attitude of the floating crane can be realized via the method for monitoring the hoisting operation work attitude of the floating crane obtained from the technical scheme, and simultaneously corresponding devices are controlled to perform corresponding adjustment on the floating crane so as to ensure the hoisting construction operation quality and safety of the floating crane.

Description

Technical field: [0001] The invention relates to a method for monitoring the safety of the working attitude of the lifting operation, in particular to a method for monitoring the safety of the working attitude of the floating crane. Background technique: [0002] Large-scale floating crane is a kind of water lifting equipment that can carry out fixed-point construction operations in waterways or coastal waters, such as the installation of bridges and bridges, the lifting of large pieces of oil platforms, and the salvage of sunken ships. When carrying out fixed-point lifting construction operations, the working attitude of the floating crane must be monitored to make the lifting operation of the floating crane safe and stable. [0003] The working attitude of the floating crane includes the heading azimuth angle relative to true north, the trim angle of bow and stern, and the heel angle of port and starboard. Adjust the azimuth angle of the floating crane by adjusting the si...
