Abstract

The invention provides a winch load simulation experimental device and method for an ocean ship. The device comprises a load winch, a testing device, a hydraulic system and a control system. The load winch comprises a base, a hydraulic motor, a testing winding drum and a speed reducer, wherein the hydraulic motor, the testing winding drum and the speed reducer are mounted on the base. The hydraulic motor is connected with the input end of the speed reducer through a universal joint. The output end of the speed reducer is connected with the testing winding drum through a coupling. The hydraulic motor is connected with the hydraulic system. A mooring rope is wound around the testing winding drum, and one end of the mooring rope is connected with a to-be-tested winch after penetrating the testing device. The testing device comprises a supporting frame. A higher first pulley and two lower second pulleys are mounted on the supporting frame, and the two second pulleys are arranged on the two sides of the first pulley correspondingly. A pressure sensor used for detecting the bearing pressure of the first pulley and a rotating speed sensor used for detecting the rotating speed of the first pulley are mounted on the supporting frame. The two second pulleys press the mooring rope on the testing winding drum to the first pulley.

Description

technical field [0001] The invention relates to a load simulation experiment device and method of a marine winch. Background technique [0002] At present, the conventional loading methods of winch test equipment include counterweight, dynamometer and friction plate. Among them, the tower-type counterweight mechanical transmission method is adopted, the equipment is heavy, the floor area is large, and the construction is difficult. There are great safety hazards in the actual operation process, and some performance data of the winch tested have defects. The continuous load and driving torque of the working condition, the measured hoisting speed of the winch is the average speed, and the speed change of the winch cannot be measured. The loading method of the dynamometer is adopted, and the loading work is completed by using the principle of motor backward dragging, but when the load is measured, it can only be operated passively, and cannot be actively loaded, and the perfor...
