Description
Technical field
Particularly a kind ofly can stretch, the oil-extraction vehicle cantilever of lifting, swing in the utility model design oil-extraction vehicle field.
Background technology
Oil-extraction vehicle since the strong characteristics of its flexibility at flank well, stripper well, non-transformer well and the oil well that is not suitable for laying oil pipeline obtained using widely, can realize taps the latent power gathers; And existing oil-extraction vehicle cantilever is generally fixed structure, needs to position by car, locatees very inconveniently, influences efficiency of construction.
Summary of the invention
The purpose of this utility model is that design a kind ofly can be stretched, the oil-extraction vehicle cantilever of lifting, swing, thereby has overcome by the oil-extraction vehicle location defect, only can accurately locate by cantilever.
The technical solution of the utility model is: design a kind of oil-extraction vehicle cantilever, which comprises at least the staking that is fixed on the oil-extraction vehicle, it is characterized in that: the staking top is hinged with the rear end of the flat frame of rotation, rotate flat frame and be rotatably connected to outer arm by vertical shaft, outer arm slidely connects inner arm, telescopic oil cylinder is movably connected on the outer arm, the clutch end of telescopic oil cylinder and inner arm flexibly connect, rotating the front end bottom of flat frame and the clutch end of hoist cylinder flexibly connects, hoist cylinder is fixed on the oil-extraction vehicle by cylinder bracket, the clutch end of outer arm bottom and oscillating oil cylinder flexibly connects, and oscillating oil cylinder is movably connected in the side of the flat frame of rotation.
Described staking is divided into left and right two parts, rotating flat frame is isosceles trapezoidal structure, two base angle ends that rotate flat frame are hinged with left and right two staking tops respectively, vertical shaft is fixed on the middle part, trapezoidal bottom of the flat frame of rotation, the front end of outer arm places the trapezoidal of the flat frame of rotation to go up on the base, the clutch end of hoist cylinder flexibly connects with the trapezoidal bottom, base of going up of the flat frame of rotation, and oscillating oil cylinder is movably connected on the trapezoidal side waist of the flat frame of rotation.
Described inner arm front end has the metering pulley.
The beneficial effects of the utility model are: owing to slidely connect inner arm on outer arm, telescopic oil cylinder is movably connected on the outer arm, the clutch end of telescopic oil cylinder and inner arm flexibly connect, so outer arm can be under the effect of telescopic oil cylinder stretches out or withdraw along inner arm, have realized stretching of cantilever; Rotating the front end bottom of flat frame and the clutch end of hoist cylinder flexibly connects, the trapezoidal base end of going up of the flat frame of driven rotary raises jointly in the hoist cylinder uphill process, because two base angle ends of the flat frame of rotation are hinged with left and right two staking tops respectively, therefore rotating flat frame can be the rotating shaft rotation with trapezoidal bottom, thereby the lifting of fixing outer arm has realized the lifting of whole cantilever on the flat frame of driven rotary; Drive outer arm in the flexible process of oscillating oil cylinder and be left and right slip in the scope on rotating shaft base on the flat frame of rotation trapezoidal, thereby realized the left and right swing of whole cantilever with the vertical shaft.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, staking; 2, rotate flat frame; 3, vertical shaft; 4, outer arm; 5, inner arm; 6, metering pulley; 7, telescopic oil cylinder; 8, hoist cylinder; 9, oscillating oil cylinder; 10, cylinder bracket.
The specific embodiment
This oil-extraction vehicle cantilever as Fig. 1 is made up of staking 1, the flat frame 2 of rotation, vertical shaft 3, outer arm 4, inner arm 5, metering pulley 6, telescopic oil cylinder 7, hoist cylinder 8, oscillating oil cylinder 9, cylinder bracket 10.
Staking 1 is divided into left and right two parts, rotating flat frame 2 is isosceles trapezoidal structures, two base angle ends that rotate flat frame 2 are hinged with left and right two stakings 1 top respectively, vertical shaft 3 is fixed on the middle part, trapezoidal bottom of the flat frame 2 of rotation, rotate flat frame 2 and be rotatably connected to outer arm 4 by vertical shaft 3, the front end of outer arm 4 places trapezoidal the going up on the base of the flat frame 2 of rotation to horizontally slip; The clutch end of hoist cylinder 8 flexibly connects with the trapezoidal bottom, base of going up of the flat frame 2 of rotation, the trapezoidal base end of going up of the flat frame 2 of driven rotary raises jointly in hoist cylinder 8 uphill process, because two base angle ends of the flat frame 2 of rotation are hinged with left and right two stakings 1 top respectively, therefore rotating flat frame 2 can be the rotating shaft rotation with trapezoidal bottom, thereby the lifting of fixing outer arm 4 has realized the lifting of whole cantilever on the flat frame 2 of driven rotary; Oscillating oil cylinder 9 is movably connected on the trapezoidal side waist of the flat frame 2 of rotation, see Fig. 2, drive outer arm 4 in the flexible process of oscillating oil cylinder 9 with left and right slip in the scope on vertical shaft 3 base that be rotating shaft on rotating flat frame 2 trapezoidal, thereby realized the left and right swing of whole cantilever, rotating flat frame 2 can also be rectangular configuration.
