Two-beam overturning gantry crane

Abstract

The invention relates to a two-beam overturning gantry crane and belongs to a large loading and unloading machine. The two-beam overturning gantry crane is characterized by comprising a two-beam gantry frame and a two-layer trolley. The two-beam overturning gantry crane has the function of overturning, loading and unloading goods. The two-beam overturning gantry crane is suitable for production operation of overturning and cleaning bulk grain containers, and has all the functions of a common two-beam gantry crane.

Description

technical field [0001] The invention relates to a double-girder overturning gantry crane, which belongs to the field of loading and unloading machinery. Background technique [0002] Double-girder gantry crane is a large-scale loading and unloading machine commonly used in railways and ports. The existing common double-girder gantry crane is composed of double-girder gantry frame, lifting trolley, cab and other components. The cab is usually installed on the lower part of the longitudinal beam of the double girder gantry, and some gantry cranes install the cab on the lower part of one end of the trolley. The lifting trolley straddles the longitudinal beam of the double girder gantry. The lifting trolley is equipped with a fixed hoisting hoisting device. The hoisting device cannot move on the trolley. The hook is suspended below the center point of the hoisting trolley through a wire rope. , the hook head of the hook is the lifting point of the gantry crane. When loading and...

AI Technical Summary

Problems solved by technology

The lifting trolley straddles the longitudinal beam of the double girder gantry. The lifting trolley is equipped with a fixed hoisting hoisting device. The hoisting device cannot move on the trolley. The hook is suspended below the center point of the hoisting trolley through a wire rope. , the hook head of the hook is the lifting point of the gantry crane. When loading and unloading cargo, the lifting point coincides with the center of gravity of the cargo, and the line between the two points is always perpendicular to the ground. The line is perpendicular to the center of gravity of the goods and coincides with each other, and the moment of the lifting force to the center of gravity of the goods is zero. The existing ordinary double-beam gantry can only lift or drop the goods, but cannot tilt or turn the goods over

The existing ordinary Shuanglianglong does not have the function of tipping and loading and unloading goods, and cannot fully meet the actual needs of modern production
