Six-freedom-of-degree movement trolley

Abstract

The invention relates to a six-freedom-of-degree movement trolley. The six-freedom-of-degree movement trolley comprises a travelling support and a worktable; travelling wheels are installed at the four corners of the bottom of the travelling support correspondingly, the two front travelling wheels are separately driven by a motor, and the two rear travelling wheels are universal wheels; the worktable is installed on the top face of the travelling support, three retractable mechanisms are installed between the worktable and the travelling support, and each retractable mechanism comprises two servo electric cylinders; the bottoms of the servo electric cylinders are separately hinged to the travelling support through universal connectors to form three lower hinge point sets which are distributed in a regular triangular mode, the extension ends of all the servo electric cylinders are hinged to the bottom of the worktable through universal connectors, and three upper hinge point sets, which are distributed in a regular triangular mode, are installed on the bottom face of the worktable; the projections of the three upper hinge point sets and on the travelling support are located at the midpoints of the three sides of a regular triangle formed by the three lower hinge point sets correspondingly, the two adjacent servo electric cylinders between each two retractable mechanisms are hinged to the same upper hinge point set between the two retractable mechanisms.

Description

technical field [0001] The invention relates to a sports trolley, in particular to a sports trolley equipped with a six-degree-of-freedom workbench. Background technique [0002] Sports trolleys are usually used when transporting heavy objects such as raw materials or parts in the production workshop. The moving trolleys in modern production workshops are usually rail trolleys or trolleys. The movement route of the rail trolleys is fixed and the flexibility is not strong. The route of the trolley during transportation is difficult to control, and it is easy to go astray, which requires constant correction. The working tables of the above two kinds of sports trolleys are usually fixed or can be lifted, and the degree of freedom is not high, so they cannot be assisted and adjusted during unloading. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide an electric-driven moving trolley whose...
