The utility model is to realize by technical scheme below:
The large supporting leg crawler crane of a kind of arrow gauge, comprise: vehicle frame, two crawler belts that are connected with vehicle frame bottom, the supporting leg being connected with vehicle frame top, the turntable being connected by pivoting support with frame chassis, the anterior principal arm arranging of turntable, arm, mast are surpassed, the tower arm, the rear pole that are connected with principal arm, the front strut being connected with tower arm, with the super-starting balance weight that has surpassed the suspension of arm top, it is characterized in that: described crawler belt is that a kind of gauge is the narrow gauge crawler belt of 3.8m the maximum ground connection width of crawler belt 5.3m; Described supporting leg is the large supporting leg that a kind of 4 of being connected with vehicle frame top can horizontally rotate, and supporting leg head is equipped with oil cylinder that can be vertically flexible, and large leg disc is arranged at oil cylinder bottom; Described pivoting support is a kind of fast disassembly type pivoting support, and it is to be connected with bearing pin with turntable, frame chassis; The power unit device of the external car load of one side of described turntable.
The utility model uses for wind-powered electricity generation place, has the following advantages and beneficial effect:
1, large supporting leg both can improve from dismounting efficiency, the stability of car load can improve again arm and lifting time.
2, narrow gauge crawler belt good fluidity, condition of road surface requires low, is particularly useful for lifting wind-powered electricity generation place frequently.
3, fast disassembly type pivoting support, the separation of convenient for passenger to get on and off body, reduces shipping height, reduces single-piece shipping mass, has improved transition conveying efficiency.
4, on turntable, power unit is external, facilitates the maintenance of hydraulic pressure electric components.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (front view);
Fig. 2 is the structural representation (birds-eye view) of turntable;
Fig. 3 is the off working state schematic diagram of supporting leg;
Fig. 4 is the working state schematic representation of supporting leg.
The specific embodiment
The utility model is further described by embodiment below in conjunction with accompanying drawing:
As shown in Figure 1,2,3, 4, the large supporting leg crawler crane of a kind of arrow gauge, comprise: vehicle frame 1, two crawler belts 2 that are connected with vehicle frame bottom, the supporting leg 3 being connected with vehicle frame top, the turntable 5 being connected by pivoting support 4 with frame chassis, the anterior principal arm 6 arranging of turntable, arm 10, mast 11 are surpassed, the tower arm 7, the rear pole 9 that are connected with principal arm 6, the front strut 8 being connected with tower arm, with the super-starting balance weight 12 that has surpassed the suspension of arm top; Described crawler belt 2 is that a kind of gauge is the narrow gauge crawler belt of 3.8m, the maximum ground connection width of crawler belt 5.3m; Described supporting leg 3 is large supporting legs that a kind of 4 of being connected with vehicle frame top can horizontally rotate, and supporting leg head is equipped with oil cylinder 3-1 that can be vertically flexible, and large leg disc 3-2 is arranged at oil cylinder bottom; Described pivoting support 4 is a kind of fast disassembly type pivoting supports, and it is to be connected with bearing pin with the chassis of turntable 5, vehicle frame; The power unit device 15 of the external car load of one side of described turntable 5.
Vehicle frame 1 is the box-structure that adopts high tensile steel plate welding, and vehicle frame bottom connects two crawler belts 2, and the reductor that motor drives is equipped with at four angles of track frame.
Turntable 5 is that main body adopts twin I-beam, the middle structure that connects box crossbeam, and turntable rear portion maximum can be placed 160 tons of counterweights 13, and the hoisting mechanism 14 that hoists is placed at middle part, and front portion is installed principal arm 6, surpassed arm 10, mast 11, driver's cab 16 etc.Power unit device 15 is placed on turntable one side, can take apart with turntable.Driver's cab 16 pitching up and down, left and right revolution.
Turntable 5 can be realized around getting off 360 ° of rotations, removes the connection bearing pin on pivoting support, can realize the separation of upper and lower car body.
