The specific embodiment:

There is thrust baring 17 to captive joint between support 1 and the fuselage 2 through bolt 18, fuselage 2 is connected by the beam warp axle sleeve 9 on them with arm 3, the bottom of fuselage 2 is connected with weight vehicle 4, the revolving wheel 14 of winch 5 and 360 ° of rotations on circuit orbit 27, weight vehicle track 25 1 ends are through revolving wheel support 24 and revolving wheel 14, support 21 connects, the other end is connected with fuselage 2, constitute triangle, weight vehicle track 25 is 15-20 ° with horizontal angle α, being connected with counterweight wheel 16 on the weight vehicle 4 is connected with weight vehicle track 25 running-fits, fuselage 2 upper ends are connected with cutout relay 13, the upper end of piston rod 7 is connected with roller 6, roller sliding plate 32 on roller (6) and the arm 3 rolls and is connected, piston hydraulic cylinder 8 is connected with plunger piston fluid pressure cylinder 10 through oil pipe 11, plunger piston fluid pressure cylinder 10 is connected with weight vehicle 4 through bolt 18, the winch 5 of fuselage 2 bottoms, steel rope 12 is through pulley 19, fixed pulley 20, suspension hook 22 is connected with hopper 23 dynamic duties.Hydraulic process: when moving down under the piston carrying force effect of piston liquid tooth mug, liquid enters into the plunger piston fluid pressure cylinder cylinder body by oilhole, oil pipe, the promotion plunger moves, and it is mobile backward at track to promote weight vehicle by plunger, realizes the balance purpose of suspended object counterweight.Working process of the present invention: when winch to rotating counterclockwise, pulling steel rope, by fixed pulley lifting hopper.Owing to by being hung the hopper own wt, move downwards on the front end of arm, the compressing hydraulic cylinder piston moves down, and by liquid power is sent to plunger piston fluid pressure cylinder, promotes plunger and moves after with weight vehicle, till kept in balance between hopper and the counterweight.Hopper begins to be sling, and when hanging certain altitude, rotating fuselage by hand can 360 ° of rotation.After unloading lower feed box, weight vehicle is got back to original position under the effect on inclined-plane, still the transmission by hydraulic power, arm and cutout relay, winch are quit work, take down the part object, when making the hanging object total weight be equal to or less than rated weight, arm lifts cutout relay and resets, power supply is switched on, the winch normal operation that restores electricity.

The counter-rotation winch, object is put down, and under the effect on gravity slope, weight box returns to original position.When suspended object weight during greater than rated weight, weight box is walked to the travel switch place, promotes travel switch, the winch outage.Take down the part suspended object, when making the object total weight be equal to or less than rated weight, travel switch is connected, and winch restores electricity, normal operation.The utility model is that the weight and the object of object moves the required resistance that overcomes at natural downslide on the inclined-plane and object on the inclined-plane.The utility model and traditional hoisting crane comparison have improved work efficiency.With 0.5 ton hoisting crane is example, in the automobile handling goods, can save 10 labour powers, can save 20-50 labour power in the building ground.Safe and reliable.By this machine counterweight, winch the bottom of complete machine, the stability and the safety that have improved equipment greatly all have been designed into.
