Abstract

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.

Description

(1) Technical field: [0001] The invention relates to port hoisting machinery, in particular to a plane two-degree-of-freedom seven-rod closed-chain container front-handling crane. (2) 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,...
