Son-mother vehicle with convenience in accessing extra-large articles

Abstract

The invention provides a son-mother vehicle with convenience in accessing extra-large articles. The son-mother vehicle comprises a mother vehicle, an offset device, a son vehicle and a jacking device.The mother vehicle has a first degree of freedom of transverse extension and comprises a first driving device and a mother vehicle frame, and the mother vehicle frame can be driven by the first driving device to move along the direction of the first degree of freedom; the offset device is mounted on the mother vehicle frame; the offset device comprises a second driving device and an offset frame,and the offset frame can be driven by the second driving device to move along the direction of a second degree of freedom; the son vehicle is mounted on the offset frame and has a third degree of freedom of longitudinal extension; the jacking device is provided with a jacking platform; the mother vehicle frame and the offset frame mainly comprise box beams. The son-mother vehicle has the advantages that the problem of incapability of accessing extra-long, extra-wide and extra-heavy articles by storage equipment of existing warehousing systems can be pertinently solved by the aid of the son-mother vehicle with the novel structure, and systems are high in access capacity and bearing capacity owing to the box beams.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a composite car that facilitates the access of oversized objects. Background technique [0002] At present, in industries such as automobiles, molds, and heavy industries, there are some large-scale molds, fixtures, and workpieces that need to be stored. Disadvantages: (1) Stored directly on the site, the objects will occupy a large amount of workshop area and waste land resources. This method also has disadvantages such as low access efficiency and large safety hazards during the access process; (2) using a driving or forklift There are problems such as low access efficiency and potential safety hazards when accessing objects on shelves by other tools. In addition, this method also has the disadvantage of wasting land resources. [0003] In the modern logistics system, the automated three-dimensional warehouse has solved the problem of waste of land resources and has bec...

Problems solved by technology

The shuttle trolley moving longitudinally, the mother shuttle trolley moving horizontally, and the elevator moving vertically constitute a mother-carriage system with the shuttle trolley as the core. Although this type of system can access goods more flexibly, it takes a long time to access goods. The average width needs to be controlled within 1.5m, and the load is mostly within 2000kg, which cannot meet the transmission of super-large objects

[0007] Most of the objects that can be accessed by the access equipment in the prior art are within 2m in length and width, and within 3000kg in weight, and cannot access super-large objects
