The invention relates to the technical field of hoisting, in particular to a marine safety type hoisting tool. Comprising a connecting sleeve, the upper end of a lifting hook is elastically and slidably arranged in the connecting sleeve, one side of the lifting hook below the connecting sleeve is rotatably connected with a first gear, one side of the first gear is provided with a first rack, the first rack is meshed with the first gear, the first rack is fixed to the connecting sleeve, and a first connecting rod is fixed to the first gear; a vertical sliding rod is slidably arranged on the other side of the lifting hook in the vertical direction, a bottom plate is fixed to the lower end of the sliding rod, a second rack parallel to the sliding rod is fixed to the sliding rod, a second gear is rotationally connected to the lifting hook on one side of the second rack, the second rack is meshed with the second gear, and a second connecting rod is fixed to the second gear. When the lifting rope is located in the lifting hook and lifts, the lifting hook descends under the gravity action of an object, the first connecting rod rotates and prevents the lifting rope in the lifting hook from being separated from the lifting hook, and the situation that unhooking occurs due to the fact that the shaking amplitude of the object is too large can be avoided.
本发明涉及到一种吊装技术领域,具体涉及到一种船用安全型吊装工具。包括连接套,吊钩上端弹性滑动设置在连接套内,连接套下方的吊钩一侧转动连接有第一齿轮,第一齿轮一侧设置有第一齿条,第一齿条与第一齿轮啮合,第一齿条固定在连接套上,第一齿轮上固定有第一连接杆,吊钩另一侧的竖直方向上滑动设置有竖直的滑杆,滑杆下端固定有底板,滑杆上固定有与其平行的第二齿条,第二齿条一侧的吊钩上转动连接有第二齿轮,第二齿条与第二齿轮啮合,第二齿轮上固定有第二连接杆。吊绳位于吊钩内并起吊时,吊钩在物体的重力作用下下行,第一连接杆转动并防止吊钩内的吊绳从吊钩内脱出,能够避免物体晃动幅度过大而出现脱钩的情况发生。
