Three-degree-of-freedom link mechanism type hybrid drive reach stacker

Abstract

The invention discloses a link mechanism type hybrid-driven reach stacker with three freedom degrees. A lifting arm of the link mechanism type hybrid-driven reach stacker comprises a rotary arm, an upper lifting arm and a lower lifting arm; the front ends of the upper lifting arm and the lower lifting arm are respectively provided with a clamping device; a lifting arm lifting mechanism comprises a front connecting rod assembly and a rear connecting rod assembly which are symmetrically arranged at the two sides of the lifting arm; the front connecting rod assembly comprises a front rocking bar and a front connecting rod which are arranged under the front of the lifting arm; the rear connecting rod assembly comprises a four connecting rod mechanism and a transmission rod which are arranged behind the lifting arm, and a rear rocking bar and a rear connecting rod; the four connecting rod mechanism comprises a rocking bar, a connecting rod and an oscillating bar; the rocking bar is driven by a high-power conventional motor which is correspondingly arranged on a frame; the front rocking bar and the rear rocking bar are driven by a small-power servo motor which is correspondingly arranged on the frame. The link mechanism type hybrid-driven reach stacker has the three freedom degrees, is driven by the high-power conventional motor and the small-power servo motor in a combined way, and is flexible and changeable in output track, high in adaptability and working efficiency, high in power output and reliability and low in whole manufacturing cost and maintenance cost.

Description

(1) Technical field: [0001] The invention relates to port hoisting machinery, in particular to a three-degree-of-freedom link mechanism type hybrid drive front stacker. (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 cost...

AI Technical Summary

Problems solved by technology

[0004] For this reason, the present invention proposes a three-degree-of-freedom linkage type hybrid drive reach stacker, which mainly solves the problem of high processing and assembly requirements, short life, oil leakage, and insufficient movement of traditional two-degree-of-freedom hydraulic container reach stackers. Technical issues such as flexibility
