Abstract

The invention discloses a method for measuring a wire rope of a laying winch. The method comprises the following steps: discharging or retracting the wire rope by the winch, changing direction of the wire rope after the wire rope passes through a pulley of a measuring device, driving the pulley to rotate by the wire rope, and acquiring an output voltage signal of a tachogenerator through corresponding arrangement of a gear ring and the tachogenerator; enabling a linear transducer to generate periodic pulse current through corresponding arrangement of a spoke and the linear transducer; acquiring a tension output signal through a tension sensor on a mandrel; and calculating the speed, length and tension values for discharging and retracting the wire rope through the laying winch control device, and controlling the laying winch in real time to correct the discharging and retracting of the wire rope in time. The invention also discloses the measuring device used by the method, which guides the wire rope discharged by the laying winch according to a set direction so as to improve the measuring accuracy and response time of parameters of laying wire ropes; and the winch is not positioned on the central line of a laying operating line so as to effectively utilize space.

Description

technical field [0001] The invention belongs to the technical field of offshore oil engineering equipment manufacturing, and relates to a method for measuring steel wire ropes of a pipe-laying winch, and also relates to a measuring device used in the method. Background technique [0002] At present, with the continuous development of offshore oil exploration and development to deeper waters, the status of submarine pipeline engineering in offshore oil and gas development has become more prominent. Offshore oil and gas transmission pipelines are mostly laid by pipe-laying ships, and pipe-laying winches are important equipment for pipe-laying ships. One, generally arranged at the end of the pipelaying line, the pipelaying winch guides the steel wire rope pulling the pipeline to extend to the seabed along the set direction and target, and the measuring device on the pipelaying winch transmits the measured data to the pipelaying The control system of the winch and its operating ...
