Three degrees of freedom hybrid drive container reach stacker crane

Abstract

The invention discloses a three-degree-of-freedom hybrid drive container reach stacker crane. A suspension arm comprises a rotating arm, an upper lift arm and a lower lift arm; two ends of the rotating arm are respectively hinged with the middle front part of a cartridge and the lower corner of a triangular support; the rear end of the upper lift arm is hinged with the front corner of the triangular support, and the rear end of the lower lift arm and the rotating arm form a composite hinge; the front ends of the upper lift arm and the lower lift arm are hinged with the clamping device; a suspension arm lift mechanism comprises front, middle and rear connecting rod assemblies which are arranged symmetrically at two sides of the suspension arm; the front connecting rod assembly comprises a front rocker rod and a front connecting rod which are hinged; the front rocker rod is hinged to the front part of the cartridge, the front connecting rod is hinged with the lower lift arm; the middle connecting rod assembly comprises a middle rocker rod and a middle connecting rod which are hinged, the middle rocker rod is hinged with the middle rear part of the cartridge; the middle connecting rod is hinged with the rear corner of the triangular support; the rear connecting rod assembly comprises a rear rocker rod and a rear connecting rod which are hinged; the rear rocker rod is hinged with the rear part of the cartridge; the rear connecting rod is hinged with the rotating arm. The three-degree-of-freedom hybrid drive container reach stacker crane is subjected to multi-motor hybrid driving, is great in power, high in reliability, low in manufacturing cost, and easy to maintain.

Description

(1) Technical field: [0001] The invention relates to port hoisting machinery, in particular to a three-degree-of-freedom hybrid drive 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. . For example, the disclosed container reach cranes of CN103332220A, CN101723256A, CN202322093U, CN2773035, and CN201890746U all complete work tasks through the joint drive of telescopic oil cylinder and pitching oil cylinder. [0003] However, the above-mentioned type of 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, and maintenance costs, ...

AI Technical Summary

Problems solved by technology

[0004] For this reason, the present invention proposes a three-degree-of-freedom hybrid drive container reach-stack crane, which mainly solves the problems of traditional two-degree-of-freedom hydraulic container reach-stack cranes, which require high processing and assembly, short service life, oil leakage, and inflexible movements. question
