Abstract
Telescopic horizontal support legs are provided with a kind of telescopic leg, including outrigger box and movable supporting legs, outrigger box, horizontal support legs are connected on rear side of outrigger box by horizontal support legs oil cylinder;Horizontal support legs leading section is hinged with movable supporting legs oil cylinder and connecting rod B, and movable supporting legs oil cylinder front end is connected in the middle part of movable supporting legs;Movable supporting legs rear end is connected by the connecting rod A being hinged with horizontal support legs, and connecting rod B lower ends are hinged on the medium position of the connecting rod A pin joints and movable supporting legs oil cylinder pin joint on movable supporting legs;Movable supporting legs lower end is rotatably connected to branch legs and feet.This leg structure is compact, and space-consuming is few, and span is big, and stability is strong.Compared with common supporting leg, when movable supporting legs are withdrawn, it is completely hidden in outrigger box, is not take up the space beyond outrigger box, the other structures with main frame or chassis can be avoided to interfere with each other, and suitable for various engineering machinery.
Description
Technical field
The utility model is related to a kind of supporting leg, specifically a kind of telescopic leg.
Background technology
With the fast development of domestic industry, the machinery equipment of a variety of work posts, such as crane, crane, piling machine are occurred in that
Deng these equipment are required for stablizing itself in working condition, it is ensured that the stationarity of itself, so as to safe efficient, accurate
Work, it is however generally that be by being set some supporting legs in fuselage surrounding come support equipment, to realize the stability of work.But
Common supporting leg is generally H types supporting leg and frog type supporting leg now, and space-consuming is big, and structure is slack and undisciplined, span is small, can be to main frame or chassis
Other structures are interfered, so as to influence the normal work of supporting leg.
Utility model content
To solve the problem of supporting leg space-consuming is big now, structure is slack and undisciplined, span is small and is interfered to other structures, this
Utility model provides a kind of telescopic leg.
The utility model is realized by following technical proposals.
A kind of telescopic leg, it is characterized in that, including outrigger box and movable supporting legs, outrigger box is interior to be provided with telescopic level
Supporting leg, horizontal support legs are connected on rear side of outrigger box by horizontal support legs oil cylinder;Horizontal support legs leading section is hinged with movable supporting legs oil
Cylinder and connecting rod B, movable supporting legs oil cylinder front end are connected in the middle part of movable supporting legs;Movable supporting legs rear end passes through the connecting rod A and water that are hinged
Flat supporting leg connection, connecting rod B lower ends are hinged on the middle position of the connecting rod A pin joints and movable supporting legs oil cylinder pin joint on movable supporting legs
Put;Movable supporting legs lower end is rotatably connected to branch legs and feet.
Described telescopic leg, wherein, the rear end face of outrigger box is fixed with ring flange.
Described telescopic leg, wherein, the lower surface of branch legs and feet is covered with rubber layer.
Described telescopic leg, wherein, connecting rod B is in arch shape raised to the left.
Described telescopic leg, wherein, the front opening of supporting leg underfooting surface and outrigger box is adapted.
The beneficial effects of the utility model are:This telescopic leg, compact conformation, space-consuming is few, and span is big, stability
By force.Compared with common H types supporting leg and frog type supporting leg:1. movable supporting legs are withdrawn, it is completely hidden in outrigger box, is not take up
Space beyond outrigger box, can avoid the other structures with main frame or chassis from interfering with each other;2. supporting leg perigee distance when withdrawing
Bottom surface farther out, even if on chassis very low two class chassis, can also ensure the approach angle and departure angle of vehicle, not influence vehicle
Traveling;3. when fully extended, movable supporting legs exceed horizontal support legs, increase supporting leg span, improve main frame stability;4. applicability
By force, this leg structure can be used in the various engineering machinery for needing supporting leg.
Brief description of the drawings
Fig. 1 is stretching view of the present utility model.
Fig. 2 is retracted state schematic diagram of the present utility model.
In accompanying drawing:1st, outrigger box, 2, horizontal support legs, 3, horizontal support legs oil cylinder, 4, connecting rod A, 5, connecting rod B, 6, movable supporting legs
Oil cylinder, 7, movable supporting legs, 8, branch legs and feet, 9, flange.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As shown in drawings, a kind of telescopic leg, including outrigger box 1, horizontal support legs 2, horizontal support legs oil cylinder 3, connecting rod A4,
Connecting rod B5, movable supporting legs oil cylinder 6 and movable supporting legs 7, branch legs and feet 8 and flange 9.Horizontal support legs 2 are telescopic to be fixed on outrigger box 1
It is interior, the rear side that horizontal support legs 2 pass through the connection leg case 1 of horizontal support legs oil cylinder 3;The leading section of horizontal support legs 2 is hinged movable branch simultaneously
Leg oil cylinder 6 and connecting rod B5 upper ends, the shaft end of movable supporting legs oil cylinder 6 is connected to the middle part of movable supporting legs 2;The rear end of movable supporting legs 2
It is connected by connecting rod A4 with horizontal support legs 2, connecting rod A4 two ends are to be hinged;Connecting rod B5 lower end is hinged on movable supporting legs 7, is hinged
Point is in connecting rod A4 pin joints and the medium position of the pin joint of movable supporting legs oil cylinder 6;The lower end of movable supporting legs 2 is rotatably connected to bottom surface
It is covered with the branch legs and feet 8 of rubber layer.The rear end face of outrigger box 1 is fixed with the ring flange 9 of installation;Connecting rod B5 is in arch raised to the left
Shape.
The utility model telescopic leg, it is convenient and reliable by hydraulic control, propped up using part connecting rod A4, connecting rod B5, activity
The linkage that leg oil cylinder 6 and movable supporting legs 7 are constituted, movable supporting legs 7 are deployed or withdrawn, and movable supporting legs 7 are hidden in after withdrawing
In horizontal support legs 2.In extending action, offer power is first stretched out by horizontal support legs oil cylinder 3, with horizontal support legs 2 and level branch
Part inside leg(Connecting rod A4, connecting rod B5, movable supporting legs oil cylinder 6, movable supporting legs 7 and branch legs and feet 8)Stretch out together, it is then movable
Support oil cylinder 6 stretches out, by the linkage of composition with expansion movable supporting legs 7;When withdrawal is acted, movable supporting legs oil cylinder 6
Shrink, withdrawn by the linkage of composition with connecting rod A4, connecting rod B5, movable supporting legs oil cylinder 6, movable supporting legs 7 and branch legs and feet 8
To inside horizontal support legs 2, then horizontal support legs oil cylinder 3 is withdrawn, and whole horizontal support legs 2 are retracted into inside outrigger box 1, branch legs and feet 8
