The invention provides a trailer container overturning oil cylinder and overturning fulcrum structure which comprises an overturning cross beam assembly (3) fixedly connected with a frame longitudinalbeam (7), a lower oil cylinder base (8) fixedly connected with the frame longitudinal beam (7), and an oil cylinder (6) borne on the lower oil cylinder base (8). The connecting line of an end part (10) of the overturning cross beam assembly (3) and the central point of the oil cylinder base is in a plane perpendicular to the central plane of a frame. The connecting line of the central point of the oil cylinder base and overturning fulcrums is located in the same plane, the plane is perpendicular to the central plane of the frame, and torque to the frame during overturning is reduced; the trailer container overturning oil cylinder and the overturning fulcrum structure are changed into a goose wing form, when goods are unloaded, one side of each overturning fulcrum directly transmits forceto the overturning cross beam assembly, and a girder is not directly stressed and is not prone to deformation; the lifting force of the oil cylinder is directly transmitted to the lower oil cylinder seat, the girder is uniformly stressed, and the service life of a semitrailer is prolonged; the overturning fulcrums are arranged on the left and right sides of the frame, so that field unloading is facilitated.

    本发明提供了一种挂车货箱翻转的油缸与翻转支点结构,包括与车架纵梁(7)固定连接的翻转横梁组件(3),与车架纵梁(7)固定连接的下油缸座(8),承载于下油缸座(8)上的油缸(6),所述翻转横梁组件(3)的端部(10)和油缸底座中心点的连线在与车架中心面相垂直的面内。将油缸底座中心点与翻转支点的连线处于同一个平面内,该平面与车架中心面垂直,减少翻转时对车架的扭矩;将挂车货箱翻转的油缸与翻转支点结构变为雁翅形式,卸载货物时,翻转支点一侧直接将力传给翻转横梁组件,大梁不直接受力,不易变形;油缸举升力直接传给下油缸座,大梁受力均匀,延长半挂车使用寿命;车架左右都设有翻转支点,方便现场卸货。
