Description
Technical field
The utility model relates to a kind of leg structure, particularly a kind of leg structure that is used for high-altitude operation platform.
Background technology
During aerial platform work, supporting leg struts, and allows complete machine and load weight be delivered on each supporting leg by subframe, regulates the car body level by supporting leg, guarantees the stability under aerial platform in working order.Supporting leg adopts cylinder pushes mostly, and common supporting leg pattern has following several: W-outrigger, this supporting leg is flexible only need an oil cylinder.This kind supporting leg pattern good stability, but structure relative complex, and each supporting leg is in height regulated difficulty separately, the difficult vehicle frame level that guarantees.H type supporting leg, the span of this kind supporting leg pattern is big, and each supporting leg can be regulated separately, and is good to operation field and ground-surface comformability, and shortcoming is that weight is big, and height of landing leg is big, influences working space.X type supporting leg staggers before and after the left and right sides Convenient table of this supporting leg, is hinged on the vehicle frame, and vertical oil cylinder acts on the Convenient table.X type supporting leg can stretch in the oblique angle, and each supporting leg can be regulated height separately, but supporting leg hinge number is more, when travelling the ground Clearance little, the pressure ratio H type supporting leg height of vertical oil cylinder.
More than various supporting legs different applicables area is arranged, frog type supporting leg and X type supporting leg are usually used on the hoisting crane of medium and small tonnage, during H type supporting leg is widely used in, in the large-tonnage lifting, special-purpose high empty wagons car in light weight, little by width, that gradient adaptive capacity is strong all has weak point but above several supporting leg pattern is used in.Frog type and X type supporting leg are unfavorable for the car load layout; H type supporting leg is not usually stretched supporting leg to the greatest extent for operation when the operation of narrow and small place, has certain potential safety hazard.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of leg structure that is used for high-altitude operation platform is provided.The utility model is easy to adjust, adapts to the needs of complicated grounds such as stair, ramp, pit, and of the present utility model simple in structure, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of leg structure that is used for high-altitude operation platform is characterized in that: comprise supporting leg seat, upper supporting leg, following supporting leg, support oil cylinder, secondary leg, joint tooth and leg; On the described supporting leg seat fixed link that is connected with high-altitude operation platform is installed, the lower end of described upper supporting leg is movably connected on the supporting leg seat, and the upper end of described upper supporting leg flexibly connects by joint tooth and following supporting leg; The lower end of described support oil cylinder is movably connected on the supporting leg seat, and the upper end of described support oil cylinder flexibly connects with following supporting leg; The described lower end of supporting leg down is equipped with secondary leg, and described secondary leg is installed on the leg.
Above-mentioned a kind of leg structure that is used for high-altitude operation platform, described joint tooth comprises the toothed disc one that is fixed on down on the supporting leg and is meshed with toothed disc one and is fixed on toothed disc two on the upper supporting leg, described toothed disc one and toothed disc two are provided with tapped bore, are provided with adjusting shaft in the described tapped bore.
Above-mentioned a kind of altitude effect flat-bed leg structure that is used for, described secondary leg is connected with following supporting leg by locating dowel pin.
The utility model compared with prior art has the following advantages: the utility model is by being provided with the joint tooth, and the angle of conveniently adjusted upper supporting leg and following supporting leg can adapt to the needs of complicated grounds such as stair, ramp, pit; The utility model can carry out angular adjustment between the flexible and upper supporting leg of horizontal hunting, vertical oscillation, secondary leg and following supporting leg, and open during its work area greatly, to pack up size little.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
A kind of leg structure that is used for high-altitude operation platform as shown in Figure 1 comprises supporting leg seat 1, upper supporting leg 10, following supporting leg 5, support oil cylinder 3, secondary leg 8, joint tooth 9 and leg 7; The fixed link 2 that is connected with high-altitude operation platform is installed on the described supporting leg seat 1, and the lower end of described upper supporting leg 10 is movably connected on the supporting leg seat 1, and the upper end of described upper supporting leg 10 flexibly connects by joint tooth 9 and following supporting leg 5; The lower end of described support oil cylinder 3 is movably connected on the supporting leg seat 1, and the upper end of described support oil cylinder 3 flexibly connects with following supporting leg 5; The described lower end of supporting leg 5 down is equipped with secondary leg 8, and described secondary leg 8 is installed on the leg 7.Described joint tooth 9 (as shown in Figure 2) comprises the toothed disc 1 that is fixed on down on the supporting leg 5 and is meshed with toothed disc 1 and is fixed on toothed disc 2 12 on the upper supporting leg 10, described toothed disc 1 and toothed disc 2 12 are provided with tapped bore 13, are provided with adjusting shaft 4 in the described tapped bore 13; Described secondary leg 8 is connected with following supporting leg 5 by locating dowel pin 6.
During use, the leg structure that is used for high-altitude operation platform described in the utility model is four, be installed in respectively on four angles of high-altitude operation platform, when enabling this leg structure, by rotating adjusting shaft 4 toothed disc 1 is separated with toothed disc 2 12, supporting leg 5 makes down the angle between supporting leg 5 and the upper supporting leg 10 reach the angle value that needs under the manual regulation, and then thereby rotation adjusting shaft 4 makes toothed disc 1 and toothed disc 2 12 engagements fix this angle value, again that leg 7 is fixing, start support oil cylinder 3, under the promotion of support oil cylinder 3, following supporting leg 5 rotates around leg 7, thereby with the job platform lifting; When packing up, start support oil cylinder 3 piston rod of support oil cylinder 3 is regained, job platform landing this moment makes toothed disc 1 separate with toothed disc 2 12 by rotating adjusting shaft 4 again, and supporting leg 5 is packed up supporting leg 5 under the manual regulation.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
