Measuring device and measuring method for gravity center of ship weight

The invention provides a ship weight gravity center measuring device and method. The measuring device comprises a tool platform, a vertical supporting hydraulic oil cylinder, a weighing sensor, a rotatable contact tool and the like. During measurement, four sets of measuring devices are arranged at four corners, a ship body falls on an upper contact piece of the rotatable contact tool, the weight of the ship is directly measured through the weighing sensor, and the gravity center position of the ship is obtained through calculation. The whole measuring device is simple and convenient to operate, and in the whole process, only four sets of tools need to be moved to the site, a ship is put on, and the horizontal state and the inclined state are adjusted; data measured by the measuring device are accurate, accurate inclination data can be obtained only through a simple tool such as a graduated scale, and influence factors of component force in the horizontal direction are eliminated by arranging the bearing.
