Abstract

The invention discloses a plane two-degree-of-freedom eleven-rod double closed-loop sub-chain type container front-handling mobile crane. The plane two-degree-of-freedom eleven-rod double closed-loop sub-chain type container front-handling mobile crane comprises a suspension arm and a suspension arm hoisting and retracting mechanism, wherein a rotary arm of the suspension arm is hinged with the back part of a frame; a retractable arm is mounted on the rotary arm by a sliding pair; the retractable arm is provided with a clamping device; the suspension arm hoisting and retracting mechanism comprises five-connection-rod mechanism assemblies which are symmetrically arranged on the two sides of the suspension arm; each five-connection-rod mechanism assembly comprises a front four-connection-rod mechanism, a front assembly connection rod, a back assembly connection rod and a back four-connection-rod mechanism; each front four-connection-rod mechanism is arranged on the front part of the rack and each back four-connection-rod mechanism is arranged in the middle of the rack; the lower end of each front assembly connection rod is in compound hinging with a connection rod hinging point of each front four-connection-rod mechanism; the lower end of each back assembly connection rod is in the compound hinging with a connection rod hinging point of each back four-connection-rod mechanism; the upper ends of each front assembly connection rod and each back assembly connection rod are hinged on the suspension arm respectively. The plane two-degree-of-freedom eleven-rod double closed-loop sub-chain type container front-handling mobile crane has the advantages of small movement inertia, flexible track output, high precision, good rigidity, 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 eleven-rod double-closed-loop sub-chain front-handling crane for containers. (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 man...
