Planer two-degrees-of-freedom eleven-rod servo drive container reach stacker crane

Abstract

The invention relates to a planer two-degrees-of-freedom eleven-rod servo drive container reach stacker crane which comprises a boom, a boom elevating mechanism and a boom telescopic mechanism, wherein the boom comprises a swivel arm and a telescopic arm; the lower end of the swivel arm is hinged with the middle of a carriage; the telescopic arm is mounted on the swivel arm by a sliding pair; the telescopic arm is provided with a clamping device; the boom telescopic mechanism is arranged in front of the boom, and comprises a telescopic four-link mechanism and a telescopic transmission rod which are arranged symmetrically at both sides of the telescopic arm; the front end of the telescopic transmission rod is hinged with the telescopic arm, and a hinged point between the rear end of the telescopic transmission rod and a telescopic link form a compound hinge; the boom elevating mechanism is arranged behind the boom, and comprises an elevating four-link mechanism and an elevating transmission rod arranged symmetrically at both sides of the swivel arm; the front end of the elevating transmission rod is hinged with the swivel arm, and a hinged point between the rear end of the elevating transmission rod and an elevating link form a compound hinge. The planer two-degrees-of-freedom eleven-rod servo drive container reach stacker crane has the advantages of small motion inertia, flexible trace 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 eleven-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, maintenan...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a two-degree-of-freedom eleven-rod servo-driven container reach-stack crane, which can better solve the problem of high processing and assembly requirements, high maintenance costs, short service life, and leakage of traditional hydraulic container reach-stack cranes. oil and other disadvantages
