Abstract
The utility model relates to the field of hoisting and transporting equipment, in particular to a crab-claw type outrigger device, which comprises a bushing, a small outrigger arm, a large outrigger arm and an outrigger seat. The device is characterized in that one end of the large outrigger arm is hinged with the outrigger seat, a folding oil cylinder is disposed between the large outrigger arm and the outrigger seat, the other end of the large outrigger arm is hinged with the small outrigger arm, a folding oil cylinder is arranged between the small outrigger arm and the large outrigger arm, the outer end of the small outrigger arm is provided with an outrigger support oil cylinder and the bushing is mounted below the outrigger support oil cylinder. The device has fine rigidity of the outrigger and light weight, is practical in medium and large span, meets requirement of foldable outriggers, and is suitable in occasions with limitation on outrigger weight.
Description
Technical field
The utility model relates to the weight-hauling equipment field, and specifically a kind of crab pin formula support leg device is used for weight-lifting equipment and supports.
Background technology
As everyone knows, as seen present supporting leg mode has five kinds: 1. " H " formula supporting leg; 2. " frog " formula supporting leg; 3. " X " formula supporting leg; 4. radiant type supporting leg; 5. radial type supporting leg." H " formula supporting leg is good to the ground comformability, is easy to leveling, and it is less to reclaim rear space, but flexible because of having, so weight is heavier; " frog " formula leg structure is simple, and oil cylinder quantity is few, and is in light weight, but the supporting leg span should not be too big; " X " formula supporting leg crossbeam directly supports on the ground, and is more stable than " H " formula supporting leg, but the ground Clearance is little, and horizontal displacement is arranged when making a jack; Radiant type supporting leg support reaction is big, and weight is light relatively, but because not folding taking up room greatly.
Summary of the invention
Heavier in order to overcome " H " formula supporting leg weight; " frog " formula supporting leg span is limited; " X " formula supporting leg ground Clearance is little, and horizontal displacement is arranged when making a jack; Radiant type supporting leg support reaction is big, and the big deficiency that takes up room, the purpose of this utility model are to provide a kind of crab pin formula support leg device, and it is provided with folding oil cylinder and radial type supporting leg, satisfies the folding requirement of supporting leg.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of crab pin formula support leg device, comprise leg boots, shank arm, thigh arm and supporting leg seat, it is characterized in that: thigh arm one end and supporting leg seat are hinged, be provided with folding oil cylinder between thigh arm and the supporting leg seat, the other end of thigh arm and shank arm are hinged, be provided with folding oil cylinder between shank arm and the thigh arm, the outer end of shank arm is provided with the outrigger support oil cylinder, and the leg boots are equipped with in outrigger support oil cylinder lower end.
The utility model also can be realized by following measure: the thigh arm is hinged by bearing pin and supporting leg seat.Be provided with movable middle bearing pin between thigh arm and the supporting leg seat.Middle bearing pin is by the bearing pin hydraulic oil cylinder driving.Shank arm end is hinged by the bearing pin and the thigh arm outside.
The beneficial effects of the utility model are, the supporting leg good rigidly is in light weight, in being useful for, big span, satisfy the folding requirement of supporting leg, are applicable to the conditional occasion of supporting leg weight.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model, also is expansion lateral plan of the present utility model.
Fig. 2 is a folded sides view of the present utility model.
1. leg boots among the figure, 2. shank arm, 3. thigh arm, 4. folding oil cylinder, 5. outrigger support oil cylinder, 6. folding oil cylinder, 7. in the middle of bearing pin, 8. supporting leg seat, 9. bearing pin, 10. bearing pin, 11. bearing pin oil cylinders.
The specific embodiment
In Fig. 1, Fig. 2, the utility model comprises leg boots 1, shank arm 2, thigh arm 3, folding oil cylinder 4, outrigger support oil cylinder 5, folding oil cylinder 6, middle bearing pin 7, bearing pin 9, bearing pin 10, bearing pin oil cylinder 11, supporting leg seat 8.
The utility model thigh arm 3 is connected with supporting leg seat 8 by bearing pin 9, and thigh arm 3 can rotate around bearing pin 9 under folding oil cylinder 4 drives, and middle bearing pin 7 is driven by bearing pin oil cylinder 11 and inserts and extract; Shank arm 2 ends are connected with thigh arm 3 outsides by bearing pin 10, and shank arm 2 can rotate around bearing pin 10 under folding oil cylinder 6 drives; Shank arm 2 outer ends connect outrigger support oil cylinder 5,5 times dresses of outrigger support oil cylinder leg boots 1.When supporting leg was packed up, bearing pin 7 in the middle of bearing pin oil cylinder 11 is extracted, folding oil cylinder 4, folding oil cylinder 6 shrank and drive shank arms 2 and thigh arm 3 and return back to retrieving position around bearing pin separately; When supporting leg launches, folding oil cylinder 4, folding oil cylinder 6 stretch out and drive shank arm 2 and thigh arm 3 and return back to level around bearing pin separately, bearing pin oil cylinder 11 inserts middle bearing pin 7 fixedly shank arm 2 and thigh arm 3, outrigger support oil cylinder 5 Extension supports, supporting leg is in the crane lifting service state, and supporting leg seat 8 is fastenedly connected with the crane crossbeam or welds one with the crane crossbeam.
