Abstract

The invention provides a marine crane. The marine crane comprises a hoisting mechanism, a guide pulley, a lifting hook group, a steel wire rope fixing end, a crane carriage and a trolley traction mechanism, the hoisting mechanism comprises a hoisting steel wire rope, a hoisting motor, a speed reducer and a hoisting winding drum, a movable pulley is arranged on the lifting hook group, a hoisting fixed pulley, a traction pulley, running wheels and a horizontal guide wheel are arranged on the crane carriage, and the trolley traction mechanism comprises a traction winding drum and a traction steel wire rope; the hoisting mechanism is fixedly connected with the tail part of a crane boom; one end of the hoisting steel wire rope is fixed on the hoisting winding drum, the other end of the hoisting steel wire rope sequentially penetrates through the guide pulley, the hoisting fixed pulley, the movable pulley and the hoisting fixed pulley and then is connected with the steel wire rope fixing end; the guide pulley is fixedly connected with the end part of the crane boom; the winding and unwinding directions of the two traction steel wire ropes are opposite; and the crane carriage is suspended on a lower edge wing plate of the crane. The marine crane has the advantages of being simple in structure, convenient to install and capable of meeting the use requirements of ships under complex working conditions.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a marine crane. Background technique [0002] At present, most marine cranes use standard electric hoist as the lifting and trolley running mechanism, and the standard electric hoist is designed according to the general working conditions of the workshop, and its working level can only be up to M5, which can meet the requirements for ordinary factory environments. , but in special occasions (such as ships), the traditional standard electric hoist can not meet the requirements of the working conditions. When the ship is driving on the river or sea, the large waves generated by the water will cause the crane to shake greatly. On the one hand, the operating mechanism of the crane will be subjected to a large ramp resistance, which will cause the trolley to slip and make it difficult to operate normally. On the one hand, under this working condition, the angle between the ...
