Description
Technical field
The present invention relates to the semi-trailer support technical field, specifically, relate to a kind of double pendulum base of semi-trailer support.
Background technology
The outside at superimposed trailer leading portion left and right side bar is equipped with lifting landing leg usually, to support the first half section weight of superimposed trailer, and can regulate the height of superimposed trailer front end, adapts to entering or breaking away from of traction seat; At superimposed trailer, be pulled while travelling, interior leg is retracted, and lifts away from ground, keeps a safe distance.
Semi-trailer support (bearing set) is a pair of, be arranged on superimposed trailer leading portion arranged on left and right sides, left and right supporting leg is in transmission connection by tween drive shaft, on a side leg, is provided with rocking handle, reaches the two-speed gear transmission device, makes rotatablely moving of manpower rocking handle be converted into the dipping and heaving of supporting leg.Two side legs have included outer leg, and the interior leg stretched up and down in leg outside connects the screw mandrel screw assembly of inside and outside leg transmitted load etc.In interior leg bottom, it is earth plate, when supporting leg lands, the earth plate kiss the earth, when supporting leg promotes, earth plate is mentioned and is suspended in midair with interior leg, earth plate needs the gravity that in support, leg transmits on the one hand, needs on the other hand to adapt to different evenness of road surface degree, and base designs how to optimize transmitted load, raising structural strength, reduction overall weight is also a key.
Referring to a kind of aluminum alloy supporting leg of disclosed Chinese utility model patent on October 31st, 2012, existing earth plate traditional design comprises base plate and the riser welded on base plate, base is articulated in the bottom of movable supporting legs, on riser, offer pivoted hole for movable supporting legs, connecting, around riser, be provided with a plurality of brace panels the intensity of base is met the requirements.Although the more common supporting leg of this aluminum alloy supporting leg weight is light, bearing load is lower.And riser is welded on base plate, when road surface inclination, the relative riser of movable supporting legs turned an angle, the pivoted hole of riser bore larger application force, and the structure in the pivot joint position becomes the strength weak link.
Existing steel earth plate structure is similar to above-mentioned aluminum alloy supporting leg, and its base quality is heavier.
Summary of the invention
