Detailed Description

The invention will be explained in more detail by the following examples, which disclose the invention and are intended to protect all technical improvements within the scope of the invention.

The special charging crane comprises a cart running mechanism 1, a bridge frame 2, a trolley running mechanism 3 and a lifting mechanism 4, wherein the trolley running mechanism 3 comprises a walking trolley 3.1 and a rotating trolley 3.2, the walking trolley 3.1 is correspondingly connected with the bridge frame 2, the rotating trolley 3.2 is correspondingly rotatably installed in the walking trolley 3.1, and the bottom of the rotating trolley 3.2 is correspondingly connected with the lifting mechanism 4, so that the walking trolley 3.1 can move along the bridge frame 2, the rotating trolley 3.2 can rotate inside the walking trolley 3.1, when the rotating trolley 3.2 rotates, the lifting mechanism 4 can be driven to rotate together, the material troughs 5 lifted by the lifting mechanism 4 can be driven to rotate together, the material outlets of the material troughs 5 face to the side face of a factory building and then are sequentially placed, and the placing mode can enable the space in the factory building to be more reasonably utilized; the hoisting mechanism 4 comprises two winches 4.1, two groups of pulleys 4.2, two lifting hook single beams 4.3 and two hinge rods 4.4, the two winches 4.1 are symmetrically arranged on the top surface of the rotating trolley 3.2, steel wire ropes of the two winches 4.1 are correspondingly connected with the two groups of pulleys 4.2 one by one respectively, the two groups of pulleys 4.2 are arranged on the top surface of one lifting hook single beam 4.3 respectively, the bottom surfaces of the two lifting hook single beams 4.3 are provided with lifting hooks 4.5, the lifting hooks 4.5 are used for hooking the trough 5, particularly, the lifting hooks 4.5 on the lifting hook single beam 4.3 are arranged in two numbers, and the two lifting hooks 4.5 are respectively positioned at two ends of the lifting hook single beam 4.3, namely the lifting hooks 4.5 of the hoisting mechanism 4 are four in total, so that the hoisting mechanism 4 can be more stable when lifting objects;

according to the requirement, the pulley 4.2 is hinged with the single lifting hook beams 4.3, when one lifting hook beam 4.3 rises and the other lifting hook beam 4.3 does not move, the distance between the two single lifting hook beams 4.3 is narrowed, the pulley 4.2 rotates along with a hinged point, the rolling stroke of the winch 4.1 can be reduced, and the swinging amplitude of the lifting hook 4.5 is smaller in the rising and falling processes of the single lifting hook beams 4.3; the lifting hook 4.5 is hinged with the bottom surface of the lifting hook single beam 4.3, and the lifting hook 4.5 can conveniently hook the trough 5 by rotating the lifting hook 4.5 properly along the hinged point; the homonymy one end of two lifting hook monospar 4.3 corresponds articulatedly through an articulated mast 4.4 respectively, can let through articulated mast 4.4 and keep parallel relatively between two lifting hook monospar 4.3, in addition, articulated mast 4.4 is established to articulated mast 4.4 that has flexible function, to the silo 5 of different specifications, can adjust the interval of two lifting hook monospar 4.3 through this articulated mast 4.4 to cooperate with silo 5, very much, articulated mast 4.4 is established to the hydro-cylinder, and the installation end of hydro-cylinder corresponds articulatedly with the tip of a lifting hook monospar 4.3, and the flexible end of hydro-cylinder corresponds articulatedly with the homonymy end of another lifting hook monospar 4.3, can realize the remote control of two lifting hook monospar 4.3 intervals through the hydro-cylinder, saves workman's work load to the controllable stroke of hydro-cylinder.

Implement a special reinforced hoist during, at first correspond lifting hook 4.5 with silo 5 and be connected, later two hoist engine 4.1 rolling wire rope simultaneously, let hoisting mechanism 4 hoist silo 5, then through cart running gear and dolly running gear's cooperation action, hang silo 5 to the fire door of steel furnace 6, and let the feed opening of silo 5 correspond the fire door towards steel furnace 6, keep away from hoist engine 4.1 rolling wire rope of 5 feed openings of silo this moment, the tail end of silo 5 rises promptly, the iron ore raw materials in the silo 5 just falls into steel furnace 6, accomplish reinforced operation in the steel furnace 6.

The part of the utility model not detailed is prior art.
