Description
Technical Field
The utility model relates to the field of cranes, in particular to a cargo deck crane.
Background
The cargo ship needs to be provided with a crane for carrying cargos, the working radius of the suspension arm of the existing hydraulic cargo crane is changed through the oil cylinder, the adjustment range of the existing hydraulic cargo crane is limited, the occupied area is large, the self weight is heavy, and the load of the ship is increased.
Disclosure of Invention
The utility model aims to solve the problems of the conventional cargo ship crane and provides a cargo deck crane.
The specific scheme of the utility model is as follows: the cargo deck crane comprises a fixed support, wherein the lower ends of two sides of the fixed support are respectively hinged with a suspension arm, the two suspension arms are connected into a whole through a plurality of cross rods, the front ends of the two suspension arms are provided with a hoisting cross rod, the hoisting cross rod is provided with an amplitude pulley and a hoisting pulley, the top of the fixed support is provided with a guide wheel A and a guide wheel B, the front side and the back side of the fixed support are respectively provided with a group of hoisting mechanisms, the steel wire ropes of one group of hoisting mechanisms bypass the guide wheel A and the amplitude pulley and then are connected to the fixed support, and the steel wire ropes of the other group of hoisting mechanisms bypass the guide wheel B and are connected with a lifting hook after the hoisting pulley.
The guide wheel A, the guide wheel B, the amplitude variation pulley and the hoisting pulley are all provided with a steel wire rope anti-drop mechanism.
When the lifting range is adjusted, the included angle between the suspension arm and the horizontal plane is within the range of 35-70 degrees, and the working radius of the suspension arm is 5-25 m.
The hoisting weight of the crane is 20-40 tons.
The working principle of the utility model is as follows: and one of the two groups of hoisting mechanisms is used for adjusting the elevation angle of the suspension arm so as to change the hoisting range of the suspension arm, and the other group of hoisting mechanisms is used for lifting the lifting hook so as to realize hoisting or putting down goods.
Compared with the prior art, the utility model has the following advantages: the working range is wider, the adjusting speed is high, the occupied area is small, and the self weight is small.
