The invention discloses a pitching mechanism of a gantry and the gantry, and belongs to the field of marine machinery. The pitching mechanism includes a connecting rod, a support platform, a motor, anoutput gear, a force transmission gear, a force transmission rod, a support bearing and a support base; the first end of the connecting rod and the part between the first end and the second end of afirst longitudinal beam or a second longitudinal beam are hinged, and the second end of the connecting rod is hinged to the support platform; an outer ring of the support bearing is fixed to the support platform, and the support platform is provided with a first through hole communicating with an inner ring of the support bearing; the force transmission rod penetrates through the first through hole and the inner ring of the support bearing and is fixedly connected with the inner ring of the support bearing, the extension direction of the force transmission rod is perpendicular to the support platform; the first end of the force transmission rod is coaxially connected with the force transmission gear, the force transmission gear meshes with an output gear, the output gear is connected witha motor in a drive mode, and the motor is fixed to the support platform; and the second end of the force transmission rod is connected with the support base in a threaded mode, and the support base isused for being fixed to a hull. The pitching mechanism can avoid the risk of leakage.
Description
technical field [0001] The invention relates to the field of marine machinery, in particular to a pitch mechanism of a mast and the mast. Background technique [0002] In the field of marine engineering, the gantry is an important equipment for cable laying ships to perform operations such as submarine cable laying. The mast consists of a beam, two longitudinal beams and a pulley block consisting of multiple pulleys. The two longitudinal beams are arranged opposite to each other, the first ends of the two longitudinal beams are respectively hinged on the hull, and the second ends of the two longitudinal beams are fixedly connected with the two ends of the beam respectively; 1. On at least one of the hulls, it is used to guide the steel wire rope of the winch to the middle of the crossbeam to hoist heavy objects. [0003] The pitching of the mast is realized by the telescopic oil cylinder. The cylinder body of the telescopic oil cylinder is hinged on the hull, and the tele...
