Abstract
The utility model discloses a fork scissor type hydraulic lifting and overturning mechanism comprising a box body base connecting bracket 3, a hinged connecting rod A, a hinged connecting rod B, an assembly bracket and a hydraulic cylinder, wherein the hinged connecting rods (A and B) are hinged through a pin shaft to form a crossed structure which is supported between the assembly bracket and the box body base connecting bracket 3; one end of the hydraulic cylinder is hinged to the rear end part of the assembly bracket; and the other end of the hydraulic cylinder is hinged to the hinged connecting rod B. The overturning mechanism is characterized in that the pin shaft, through which the hinged connecting rods (A and B) are hinged to form the crossed structure, is deviated from the central points of the hinged connecting rods (A and B). Through the adoption of the fork scissor type lever structure with asymmetric hinge points, the box body can be lifted hydraulically; and the box body above the fork scissor type lever structure also can be wholly inclined to one side, so that the box body can rotate with a certain angle. Therefore, the overturning mechanism has the advantage that the functions of lifting and overturning are realized simultaneously, which not only simplifies a mechanical mechanism, but also provides an effective practical novel construction machine lifting and overturning device.
