Plane two-degree-of-freedom seven-rod closed chain type reach stacker for containers

The invention relates to a plane two-degree-of-freedom seven-rod closed chain type reach stacker for containers. The plane two-degree-of-freedom seven-rod closed chain type reach stacker for the containers comprises a suspension arm and a suspension lifting and telescoping mechanism, wherein the suspension arm comprises a rotating arm and a telescopic arm; the rotating arm is hinged to the rear part of a frame; the telescopic arm is mounted on the rotating arm through a sliding pair; a clamping device is arranged at the front end of the suspension arm; the suspension arm lifting and telescoping mechanism comprises five-rod linkage mechanisms which are symmetrically arranged on the two sides of the suspension arm; each five-rod linkage mechanism comprises a front rocker, a front connecting rod, a rear connecting rod and a rear rocker; the front rockers and the rear rockers are hinged to the front part and the middle part of the frame respectively; the hinged points between the front connecting rods and the rear connecting rods are arranged on the telescopic arm. Ascending, telescoping and descending of the crane are realized under the drive of the five-rod linkage mechanisms. The plane two-degree-of-freedom seven-rod closed chain type reach stacker for the containers has the advantages of small movement inertia, flexible track output, high precision, high rigidity, excellent dynamic performance, high reliability and the like.
