Ultra-large bearing omnidirectional carrying posture adjusting platform and ground self-adaptive omnidirectional moving unit

Abstract

The invention relates to an ultra-large bearing omnidirectional carrying posture adjusting platform. The platform comprises an omnidirectional moving posture adjusting unit, an X-direction driving electric bar, a vehicle body frame, a storage battery and a control unit, wherein the omnidirectional moving posture adjusting unit comprises a moving frame, a left-hand Mecanum wheel set, a right-hand Mecanum wheel set, a driving unit and a moving structure; and the movements of the omnidirectional moving posture adjusting unit include the movements in the X and Y directions and rotation of Z-axis based on Mecanum wheels and the movements in the X, Y and Z directions and rotation of the X and Y axes based on a guide rail and a screw rod, and have eight degrees of freedom, wherein the omnidirectional movement and rotation based on the Mecanum wheels, and the movements of the X, Y and Z axes are driving movements, and the rotation of the X and Y axes is a driven movement. According to the platform, large-bearing omnidirectional motions and posture adjustment are integrated, the switching among a transfer mode, a large-range low-precision posture adjustment mode and a small-range high-precision posture adjustment mode is achieved, and the application range of a six-degree-of-freedom posture adjustment platform is effectively expanded.

Description

technical field [0001] The invention relates to the technical field of large component docking and assembly equipment in the field of heavy equipment manufacturing, in particular to a ground-enclosed mecanum wheel super-large bearing omnidirectional carrying attitude adjustment platform suitable for low spaces. Background technique [0002] In the fields of heavy equipment such as large aircraft, ships, electric power, and oceans, their products are generally assembled from multiple parts, so it is often necessary to carry out docking and assembly between parts during the production process. And the mass is too large to be directly operated manually, so it needs to be transported and assembled with the help of a large load-bearing mobile attitude adjustment platform. Existing mobile attitude adjustment platforms can be divided into wheeled trucks and mecanum wheeled trucks, because wheeled trucks and mecanum wheeled trucks generally only have two directions of movement in th...

Problems solved by technology

[0004] In order to solve the single function of the existing large-load mobile attitude adjustment platform, it is impossible to complete the in-factory transfer of super-large parts and the high-precision position and attitude adjustment of six degrees of freedom for docking and assembly at the same time; through the installation of multi-degree-of-freedom parallel attitude adjustment mechanism The large load-carrying mobile attitude adjustment platform on the car body has poor passability and a small range of attitude adjustment; in view of the above problems, the present invention provides an ultra-large load-bearing omnidirectional carrying attitude adjustment platform, which is applied to super-large heavy loads with a weight of more than 30 tons Butt jointing and assembly operations of components to solve the above technical problems
