Abstract

The invention discloses a method for monitoring anchor position and anchor line status of a floating-crane anchor winch, which is implemented on the basis of an anchor position and anchor line status monitoring device for floating-crane anchor winches. In the monitoring method, the tension of the anchor line is monitored in real time by using an anchor-line tension sensor, the length of the anchor line is monitored in real time by using an anchor winch barrel position sensor, and the anchor position is monitored in real time by using a GPS (Global Position System) orientator and a depthometer. The method can be used for accurately monitoring the anchor position and the anchor line status of the floating-crane anchor winch in real time. The method can ensure that the whole monitoring process is stable and accurate, thereby ensuring the operation quality and the operation safety of the floating crane.

Description

Technical field: [0001] The invention relates to a monitoring method of a floating crane, in particular to a method for monitoring the anchor position of a winch of a floating crane and the state of an anchor rope. 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 construction operations, it is necessary to fix the anchor position through several (usually 4 to 12) large-scale anchor winches on the bow and stern of the floating crane and on the second side, and control the anchor rope to move the ship and perform job positioning. Due to the operation of the floating crane and the wind, waves and currents at sea, the tension of the anchor rope of the anchor winch often fluctuates greatly, res...
