Abstract
Description
Technical field
The present invention relates to airport lifting table apparatus field, specifically the shear shank of a kind of airport elevating platform foldable arm.
Background technology
Shear shank is the mechanism generally used in lifting table, and general lifting table is by the horizontal and vertical tilt adjustments of special leveling cylinder implementation platform; When land lengths is longer, leveling cyclinder just cannot meet the adjustment of platform fore-and-aft tilt, causes lifting table cannot arrive the leveling position of needs.
Summary of the invention
Problem to be solved by this invention is the deficiency overcoming above-mentioned prior art, provides a kind of structure simple, the shear shank of the airport elevating platform foldable arm that levelling effect is good.
The present invention realizes with following technical scheme: the shear shank of a kind of airport elevating platform foldable arm, comprise rotating bracket and be arranged on the shear shank on rotating bracket, hoist cylinder is provided with between described interior shear shank and rotating bracket, one end of described hoist cylinder is hinged on the middle and upper part of interior shear shank, the other end of described hoist cylinder is hinged on rotating bracket, described outer shear shank is made up of outer shear arm and the folding arm shear shank being hinged on outer shear arm upper end, folding arm oil cylinder is provided with between described folding arm shear shank and outer shear arm, one end of described folding arm oil cylinder is hinged on folding arm shear shank, the other end of described folding arm oil cylinder is together with the upper end thereof of outer shear arm.
It is further: described outer shear shank is identical with interior shear shank length.
Described interior shear shank and outer shear shank symmetry hinged.
Tool of the present invention has the following advantages: the present invention, by adopting the outer shear arm of radial type, makes shear arm one end rotate, makes the fore-and-aft tilt degree adjusting range content with funtion requirement of platform.

Detailed description of the invention
The shear shank of a kind of airport elevating platform foldable arm as shown in Figure 1 to Figure 3, the shear shank comprising rotating bracket 7 and be arranged on rotating bracket 7, hoist cylinder 6 is provided with between described interior shear shank 1 and rotating bracket 7, one end of described hoist cylinder 6 is hinged on the middle and upper part of interior shear shank 1, the other end of described hoist cylinder 6 is hinged on rotating bracket 7, described outer shear shank 2 is made up of with the folding arm shear shank 5 being hinged on outer shear arm 3 upper end outer shear arm 3, folding arm oil cylinder 4 is provided with between described folding arm shear shank 5 and outer shear arm 3, one end of described folding arm oil cylinder 4 is hinged on folding arm shear shank 5, the other end of described folding arm oil cylinder 4 is together with the upper end thereof of outer shear arm 3.Rotating bracket of the present invention is provided with interconnective inside and outside shear shank, wherein interior shear shank is connected with hoist cylinder, the guide rod end of hoist cylinder is together with the middle upper end thereof of interior shear shank, the other end of hoist cylinder is hinged on rotating bracket, when shear shank moves in hoist cylinder promotes, also can drive together with the outer shear shank that connects with interior shear shank and move; Simultaneously, outer shear shank is made up of outer shear arm and folding arm shear shank, folding arm shear shank is hinged on the upper end of outer shear arm, the position that interior shear shank and outer shear shank are fixed is on outer shear arm, folding arm oil cylinder is provided with between shear arm and folding arm shear shank, the two ends of folding arm oil cylinder respectively with shear arm and folding arm shear shank hinged, the effect of folding arm oil cylinder mainly drives the corresponding outer shear arm of folding arm shear shank to rotate, thus realizes shear shank significantly fore-and-aft tilt adjustment.
The shear shank of a kind of airport elevating platform foldable arm as shown in Figure 1 to Figure 3, described outer shear shank 2 is identical with interior shear shank 1 length.Described interior shear shank 1 is hinged with outer shear shank 2 symmetry.The length of inside and outside shear shank of the present invention is the same, the length that the length of its China and foreign countries' shear shank equals outer shear arm and folding arm shear shank with, inside and outside shear shank symmetry is hinged simultaneously, when being convenient to hoist cylinder promotion shear shank motion, the stability of motion of the platform be connected with shear shank can be ensured.
