Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] control figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 , a crane with six degrees of freedom in space, its structure and connection method are:

[0025] The crane arm mechanism is formed by connecting the crane body 1, the slider 2, the boom 3, the boom 4 and the lifting tongs 11. One end of the slider 2 is connected to the crane body 1 through the first rotating pair 12. The first connecting end is connected, the first connecting end of the boom 3 is connected to the other end of the slider 2 through the second rotating pair 13, and the second connecting end of the boom 3 is connected to one end of the boom 4 through the third rotating pair 14 The other end of the boom 4 is connected with the lifting handling tongs 11 through the first ball pair 15 .

[0026] The boom telescopic mechanism is composed ...

Abstract

A space crane with six degree of freedom includes a lifting arm mechanism and an arm telescoping mechanism. The lifting arm mechanism is composed of a cargo boom and a suspension boom for the crane to complete spatial operations such as container grab, lifting and unloading; and the parallel boom telescoping mechanism consists of three mechanism sub-chains in series connection. A mechanism connection mode is adopted to enable the crane with compact structure and high reliability. The space crane with six degree of freedom can effectively overcome the shortcomings of high processing precision of hydraulic components, high maintenance cost, low reliability and easy oil leakage of a hydraulic crane, has the advantages of simple control and large work space, and can be widely used in complex operations such as container grab, lifting and unloading.

Description

technical field [0001] The invention relates to the field of lifting machinery, in particular to a space six-degree-of-freedom crane. Background technique [0002] Cranes belong to material handling machinery, which is a multi-action hoisting machinery that vertically lifts and horizontally carries heavy objects within a certain range, also known as a crane. Cranes can complete actions such as reclaiming, transporting, and unloading in one working cycle, and are being developed and used more and more widely in the market. Traditional cranes complete work tasks through the joint drive of telescopic cylinders and pitching cylinders, but this kind of cranes adopts pure hydraulic transmission, and its hydraulic system has obvious shortcomings such as high parts processing and assembly requirements and loopholes, and traditional cranes use The open-chain series structure has disadvantages such as poor rigidity, low reliability, and large cumulative error. [0003] The invention...
