Abstract

The invention relates to a plane two-degree-of-freedom nine-rod servo drive reach stacker for containers. The plane two-degree-of-freedom nine-rod servo drive reach stacker for the containers comprises a suspension arm, a suspension arm lifting mechanism and a suspension arm telescoping mechanism, wherein the suspension arm comprises a rotating arm and a telescopic arm; the lower end of the rotating arm is hinged to the middle 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 telescopic arm; the suspension arm telescoping mechanism comprises a telescopic rocker and a telescopic connecting rod; the telescopic rocker is hinged to the front part of the frame; the telescopic connecting rod is hinged to the telescopic arm and the telescopic connecting rod; the suspension arm lifting mechanism comprises a lifting four-rod linkage mechanism and a lifting transmission rod; the lifting four-rod linkage mechanism comprises front lifting rockers and rear lifting rockers, which are hinged to the rear part of the frame, as well as lifting connecting rods; the lifting transmission rod is hinged to one hinged point of the rotating arm and the lifting connecting rods. The plane two-degree-of-freedom nine-rod servo drive reach stacker for the containers realizes clamping, lifting and carrying operation of the containers under the combined driving of the suspension arm lifting mechanism and the suspension arm telescopic mechanism, and has the advantages of small movement inertia, flexible track output, high precision and the like.

Description

(1) Technical field: [0001] The invention relates to port hoisting machinery, in particular to a plane two-degree-of-freedom nine-rod servo-driven container front-handling crane. (two) background technology: [0002] The container reach stacker crane (also known as the container reach stacker) is an important port machinery, which has the advantages of convenient operation and high stacking layers, and plays an important role in various port container handling, stacking and transportation operations. . As disclosed in CN103332220A, CN101723256A, CN202322093U, CN2773035, and CN201890746U, the container reach cranes are all driven by the combined drive of the telescopic oil cylinder and the pitch oil cylinder to complete the task. [0003] However, the above-mentioned traditional container reach cranes are all purely hydraulically driven, and their hydraulic systems have disadvantages such as high requirements for parts processing and assembly, high manufacturing, maintenance...
