But, the jack up unit of existing boom crane and running gear are to be all suspended on cantilever, the tonnage that hoists of boom crane is larger, the weight of needed jack up unit and running gear is just heavier, and need cantilever to there is larger weight capacity, the volume of cantilever and quality are also just larger, have caused the increase of fixed pillar type cantilever crane own wt and more complicated structure design, have limited the load-carrying capacity of boom crane.
Utility model content
The purpose of this utility model is to provide the light-type boom crane that a kind of load-carrying capacity is large.
The technical scheme adopting in the utility model is: light-type boom crane, comprise column, cantilever, reel and the lifting motor for driving reel to rotate, on described reel, winding is for promoting the rope of article, described lifting motor and reel are fixedly installed on described column, and described cantilever is provided with the direction reverser for described rope is commutated downward.
Described lifting motor and reel are arranged on the bottom of column, and the top of described column is provided with the fixed pulley towards the bearing of trend commutation of cantilever for described rope.
Described column is hollow pillar, and described rope passes through from the hollow space of described column.
Described lifting motor and reel are arranged on the outside of described column, and the sidewall of described column is provided with the rope perforation penetrating for described rope.
Described light-type boom crane is provided with the driver train for driving described direction reverser to move along the length direction of cantilever.
Described driver train comprises that the tooth bar and the corresponding described tooth bar that are arranged on described cantilever are arranged on the gear on described direction reverser, and described direction reverser is provided with the movable motor that drives described gear to rotate.
The utility model adopts technique scheme, light-type boom crane comprises column, cantilever, reel and the lifting motor for driving reel to rotate, on described reel, winding is for promoting the rope of article, described lifting motor and reel are to be fixedly installed on described column, described cantilever is provided with the direction reverser for described rope is commutated downward, therefore, the cantilever of above-mentioned light-type boom crane does not need to bear up the weight of lifting motor and reel, and then can carry heavier article, improve load-carrying capacity, and can alleviate the requirement to cantilever weight capacity.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the utility model light-type boom crane.
The name that in figure, each Reference numeral is corresponding is called: 1 column, 2 cantilevers, 3 lifting motors, 4 reels, 5 steel ropes, 6 suspension hooks, 7 rope perforation, 8 fixed pulleys, 9 reversing machine frameworks, 10 commutation fixed pulleys, 11 tooth bars, 12 gears, 13 movable motors.
Detailed description of the invention
An embodiment of the utility model light-type boom crane as shown in Figure 1, is a kind of fixed pillar type cantilever crane, comprises column 1, cantilever 2, jack up unit and direction reverser.Same as the prior art, described cantilever 2 rotates and is assemblied in column 1 top, can under the driving of cycloidal-pin wheel speed reduction gearing, turn round.
The reel 4 that described jack up unit comprises lifting motor 3 and is in transmission connection with the mouth of lifting motor 3, lifting motor 3 and reel 4 are fixed on the chassis outer side of column 1, are arranged with steel rope 5 on reel 4, as the rope for promoting article.The free end of steel rope 5 is connected with suspension hook 6, is convenient to the hanging of weight.Described column 1 is hollow column 1, its sidewall is provided with rope perforation 7, steel rope 5 penetrates the hollow space of column 1 and arrives column 1 top from rope perforation 7, and column 1 top is provided with fixed pulley 8 corresponding to the root of cantilever 2, the bearing of trend commutation for steel rope 5 towards cantilever 2.Because steel rope 5 is to pass from the hollow space of column 1, the impact of steel rope 5 on operating personnel and lifting article therefore can avoid boom crane work time, operation is convenient.
Direction reverser comprises that reversing machine framework 9 and rotation are assemblied in the commutation fixed pulley 10 on reversing machine framework 9, and steel rope 5 is walked around this angle pulley after the fixed pulley 8 at column 1 top, makes the vertical below of its free end.The movable motor 13 that is also rotatably equipped with gear 12 on reversing machine framework 9 and rotates for driven wheel 12, on cantilever 2, be fixed with the tooth bar corresponding with gear 12 11, form running gear, under the driving of movable motor 13, reversing machine framework 9 can rely on the transmission of gear 12 and tooth bar 11 to coordinate along cantilever 2 transverse shiftings.Due to the direction reverser arranging, suspension hook 6 can have larger activity space, and operation is more flexible.
When use, column 1 is fixed on the ground by holding-down bolt, lifting motor 3, cycloidal-pin wheel speed reduction gearing and movable motor 13 are connected on corresponding control handle by control line, by controlling running, the operation of cycloidal-pin wheel speed reduction gearing and the running of movable motor 13 of lifting motor 3, can realize the lifting of weight, around the revolution of column 1 with along the advance and retreat of cantilever 2, complete the transfer to weight.Because column 1 and cantilever 2 do not need to bear the weight of jack up unit again, therefore can bear more cargo weight, and column 1 and cantilever 2 can adopt steel still less, make integral structure lighter.In addition, lifting motor 3 and reel 4 move to behind column 1 bottom, and the vibration producing in operational process can most of be absorbed by ground, thus vibration and noise while reducing cantilever 2 formula hoisting crane work.
In the above-described embodiments, lifting motor 3 and reel 4 are arranged on the bottom of column 1, steel rope 5 arranges through column 1, in other embodiment of the present utility model, lifting motor 3 and reel 4 also can be set to middle part or the top of column 1, can alleviate equally the heavy burden of cantilever 2, improve load-carrying capacity; And steel rope 5 also can be arranged on the outside of column 1.In addition, in above-described embodiment, the transverse shifting of suspension hook 6 is by gear 12 tooth bar 11 winding machines, in other embodiments, it is mobile that suspension hook 6 also can utilize other forms of actuating device to realize, for example screw-nut body, fix spindle motor at column 1 top and be connected with lead screw transmission, corresponding driving nut is set on reversing machine framework 9, can realize equally the transverse shifting of suspension hook 6.Moreover, in above-described embodiment for promote article rope adopt be steel rope 5, corresponding direction reverser is commutation locating wheel, in other embodiments, rope also can adopt other forms, for example chain, is now replaced by sprocket wheel by commutation fixed pulley 10 correspondences, can realize equally commutation.In addition, in other embodiments, direction reverser also can directly be fixedly installed on cantilever 2.
