Description
Technical field
The utility model relates to supporting leg and has the construction machinery and equipment of supporting leg, relates in particular to the movable supporting legs of variable span and has the portable construction machinery and equipment of this supporting leg.
Background technology
Existing car hosit supporting leg all is arranged to " H " shape telescopic outrigger; The supporting leg of this form is said comparatively simple from structure, be convenient to make, and installs also more convenient; But; Receive the restriction of rear overhang length and departure angle, rear support leg moves after can not be infinitely, possibly occur the not enough problem of rear stability like this; Receive the restriction of change speed gear box and transmission shaft, front leg strut can not infinitely move forward, and possibly occur the not enough problem of the place ahead stability equally.Though can solve stability problem through increasing counterweight, the increase of counterweight receives the restriction of complete vehicle weight and axle load again; Though can improve the place ahead stability through increasing by the 5th supporting leg, this makes the leg system complex structure, and weight increases the weight of, and the requirement of strength to the vehicle frame leading portion increases simultaneously; Though adopt oscillating support leg can improve front and back stability, oscillating support leg commonly used will take very big space, its commonality is relatively poor, can not be applicable to all operating modes.
The utility model content
The technical matters that the utility model will solve is the deficiency that overcomes prior art, provide a kind of simple in structure, can adjust span, improve the movable supporting legs of the variable span of stability of strutting system, and portable construction machinery and equipment with this movable supporting legs.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of movable supporting legs of variable span comprises telescopic outrigger, and the external part of said telescopic outrigger is equiped with can be through the oscillating support leg of swing adjustment span.
Said oscillating support leg comprises oscillating support leg body and oscillating oil cylinder, and said oscillating support leg body is connected with the external part of telescopic outrigger through oscillating oil cylinder.
The end of said oscillating support leg body is equiped with vertical oil cylinder, and said vertical oil cylinder lower end is equiped with feet.
Said telescopic outrigger comprise the one-level telescopic outrigger with can be along the flexible secondary telescopic outrigger of one-level telescopic outrigger.
A kind of portable construction machinery and equipment comprises vehicle frame, is equiped with the movable supporting legs of above-mentioned variable span on the said vehicle frame.
Compared with prior art, the advantage of the utility model is:
The movable supporting legs of the variable span of the utility model; External part at telescopic outrigger is equiped with the oscillating support leg that can adjust span through swing; It is simple in structure, easy for installation, and the attitude through the adjustment oscillating support leg can realize supporting the adjustment of span, has improved the stability of strutting system of supporting leg.The oscillating support leg body is connected with the external part of telescopic outrigger through oscillating oil cylinder; Telescopic outrigger can drive the oscillating support leg synchronous when regaining and advance in the one-level telescopic outrigger of telescopic outrigger; Making does not influence technical requirementss such as overall width, departure angle when supporting leg is in contraction state, do not influence the layout of vehicle chassis components such as change speed gear box, transmission shaft and vehicle bridge simultaneously yet.Be equiped with the movable supporting legs of above-mentioned variable span on the vehicle frame of the portable construction machinery and equipment of the utility model, because the movable supporting legs of above-mentioned variable span has above-mentioned technique effect, this movable type construction machinery and equipment also has the corresponding techniques effect.

Each label is represented among the figure:
1, telescopic outrigger; 2, oscillating support leg; 3, vertical oil cylinder; 4, vehicle frame; 11, one-level telescopic outrigger; 12, secondary telescopic outrigger; 21, oscillating support leg body; 22, oscillating oil cylinder; 31, feet.
The specific embodiment
Fig. 1 shows the movable supporting legs of a kind of variable span of the utility model; Comprise telescopic outrigger 1; The external part of telescopic outrigger 1 is equiped with can be through the oscillating support leg 2 of swing adjustment span; It is simple in structure, easy for installation, and the attitude through adjustment oscillating support leg 2 can realize supporting the adjustment of span, has improved the stability of strutting system of supporting leg.
In the present embodiment; Telescopic outrigger 1 comprise one-level telescopic outrigger 11 with can be along the flexible secondary telescopic outrigger 12 of one-level telescopic outrigger 11; The fixed supporting leg socket of one-level telescopic outrigger 11 and construction machinery and equipment during installation, one-level telescopic outrigger 11 and secondary telescopic outrigger 12 are all collapsible to advance fixed supporting leg.Oscillating support leg 2 comprises oscillating support leg body 21 and oscillating oil cylinder 22; Oscillating support leg body 21 is connected with the external part of secondary telescopic outrigger 12 through oscillating oil cylinder 22; Telescopic outrigger 1 can drive oscillating support leg 2 synchronous when regaining and advance in the one-level telescopic outrigger 11 of telescopic outrigger 1; Making does not influence technical requirementss such as overall width, departure angle when supporting leg is in contraction state, do not influence the layout of vehicle chassis components such as change speed gear box, transmission shaft and vehicle bridge simultaneously yet.The end of oscillating support leg body 21 is equiped with vertical oil cylinder 3, and vertical oil cylinder 3 lower ends are equiped with feet 31.
The movable supporting legs of the variable span of the utility model is when work; One-level telescopic outrigger 11, secondary telescopic outrigger 12 and oscillating support leg body 21 stretch out and put in place; Drive oscillating support leg body 21 through oscillating oil cylinder 22; Make 21 rotations of oscillating support leg body to reach desired supporting leg span, start vertical oil cylinder 3 at last, drive feet 31 through vertical oil cylinder 3 and stretch out downwards; When the movable supporting legs of the variable span of the utility model is regained; Starting vertical oil cylinder 3 driving feets 31 earlier upwards packs up; Restart oscillating oil cylinder 22 and drive oscillating support leg bodies 21 and rotate and be returned to the state parallel, again one-level telescopic outrigger 11, secondary telescopic outrigger 12 and oscillating support leg body 21 are regained with secondary telescopic outrigger 12.
Fig. 2 and Fig. 3 show a kind of portable construction machinery and equipment of the utility model; Comprise vehicle frame 4, be equiped with the movable supporting legs of above-mentioned variable span on the vehicle frame 4, be equiped with four movable supporting legs in the present embodiment; As shown in Figure 3; Through the adjustment of oscillating support leg 2, increased the support span, make the stability of portable construction machinery and equipment be greatly improved.
The above only is the preferred implementation of the utility model, and the protection domain of the utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to the protection domain of the utility model.Should propose, for those skilled in the art, in the improvement and the retouching that do not break away under the utility model principle prerequisite, these improvement and retouching also should be regarded as the protection domain of the utility model.
