Description
Technical field：
A kind of track combined crane hydraulic leg of leg is the utility model is related to, is the main building block of crane.
Background technology：
Runabout crane（Autocrane, wheel-mounted crane, crawler crane etc.）Both compact-sized, passing through property had been required
Can be good；Require there is larger supporting leg span again, increase hoisting operation stability；Also need to avoid manpower handwork as far as possible, mitigate
Labor intensity.Existing design is difficult to meet all demands.
The content of the invention：
The purpose of this utility model be to provide it is a kind of withdraw that leg structure is compact, support strength and the high leg of automaticity
Track combined crane hydraulic leg.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of track combined crane hydraulic leg of leg, employ spider-shaped structure design, including ground connection pallet, interior branch
Leg, outer supporting leg, landing leg stretching oil cylinder, middle frame, main supporting leg, main supporting leg oscillating oil cylinder, outer supporting leg oscillating oil cylinder and base.Ground connection
Pallet is installed on interior supporting leg bottom, is hinged by bearing pin and interior supporting leg.Interior leg sleeve is loaded on outer supporting leg, passes through landing leg stretching oil cylinder
Both ends hinge.Outer supporting leg and middle frame are hinged by landing leg stretching oil cylinder upper pin simultaneously.Middle frame is welded as with main supporting leg
One.Outer supporting leg oscillating oil cylinder is respectively articulated with main supporting leg and outer supporting leg loaded in main supporting leg by bearing pin.Main supporting leg bottom passes through
Bearing pin is hinged with base.Main supporting leg oscillating oil cylinder upper and lower side is hinged by bearing pin and middle frame and base respectively.Leg is track combined
Crane hydraulic leg is arranged in frame and chassis by bearing pin.The track combined crane hydraulic leg of leg can be put around bearing pin
Dynamic, adjusting support angle and walking, travel position, that the track combined crane hydraulic leg of leg is recovered into machine shape is most compact
Position.
The beneficial effects of the utility model are：It is rational in infrastructure, spider-shaped structure is employed, rotatable base, is met simultaneously
Withdrawal leg structure is compact, stretches out the demand that supporting leg supporting leg span is big, job stabilization is high.Hydraulic pressure is leaned in three section supporting leg folding and unfoldings
Oil cylinder is flexible to be realized, support strength and automaticity are high.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Fig. 2 is operation schematic diagram of the utility model in large space.
Fig. 3 is operation schematic diagram of the utility model in small space.
In figure:1 ground connection pallet, connection frame, 6 main supporting legs, 7 main supporting legs in supporting leg, 3 outer supporting legs, 4 landing leg stretching oil cylinders, 5 in 2
Oscillating oil cylinder, 8 outer supporting leg oscillating oil cylinders, 9 bases, 10 bearing pins, 11 frames and chassis.
Embodiment
As Figure 1-3, the track combined crane hydraulic leg of a kind of leg, employs spider-shaped structure design, including 1 connects
Ground pallet, join frame, 6 main supporting legs, 7 main supporting leg oscillating oil cylinders, 8 outer supporting legs in 2 in supporting leg, 3 outer supporting legs, 4 landing leg stretching oil cylinders, 5
Oscillating oil cylinder and 9 bases.1 ground connection pallet is installed on supporting leg bottom in 2, is hinged by supporting leg in bearing pin and 2.Supporting leg is set with 2
In 3 outer supporting legs, pass through 4 landing leg stretching oil cylinder both ends hinges.4 landing leg stretching oil cylinder upper pins are simultaneously by 3 outer supporting legs and 5
Connection frame is hinged.Join frame in 5 to be welded as a whole with 6 main supporting legs.8 outer supporting leg oscillating oil cylinders are distinguished loaded in 6 main supporting legs by bearing pin
Be hinged 6 main supporting legs and 3 outer supporting legs.6 main supporting leg bottoms are hinged by bearing pin and 9 bases.7 main supporting leg oscillating oil cylinder upper and lower side difference
It is hinged by bearing pin and connection frame and 9 bases in 5.The track combined crane hydraulic leg of leg by 10 bearing pins be arranged on 11 frames and
On chassis.The track combined crane hydraulic leg of leg can be swung around 10 bearing pins, adjust support angle and walking, travel position will
The track combined crane hydraulic leg of leg is recovered to machine shape most compacted location.Walking and travel position, 7 main supporting legs swing oil
Cylinder, 8 outer supporting leg oscillating oil cylinders and 4 landing leg stretching oil cylinders are retracted, and it is most compact that the track combined crane hydraulic leg of leg is in structure
State.7 main supporting leg oscillating oil cylinders, 8 outer supporting leg oscillating oil cylinders stretch out, can promote 6 main supporting legs, suit 2 in supporting leg, 3 outer supporting legs
Swing out；4 landing leg stretching oil cylinders are stretched out, and supporting leg in 2 can be promoted to stretch out, so as to increase supporting leg span as needed, improved
Weight and job stabilization.Supporting leg retracted state, 4 landing leg stretching oil cylinders can directly stretch out and promote supporting leg in 2 to stretch out support machine
Device, hoisting operation is carried out in the space of minimum.Three section supporting legs, one saves telescopic, two-section folding type, coordinates rotatable base, together
When meet that to withdraw leg structure compact, stretch out that supporting leg supporting leg span is big, demand that job stabilization is high, three section supporting leg folding and unfoldings are equal
Realized by hydraulic jack is flexible, support strength and automaticity are high.
