Heavy load three-dimensional rotating table capable of balancing overturning moment

Abstract

A heavy load three-dimensional rotating table capable of balancing overturning moment comprises a load installing rotating table, an inverted-U-shaped supporting base, a U-shaped base, a balance connection rod, a counter weight slider, an orientation rotating barrel and a rotating table base, and mainly ZYZ Euler angle three-dimensional adjustment is achieved. The load installing rotating table and the inverted-U-shaped supporting base form an upper orientation axis Z1 axis; the inverted-U-shaped supporting base and the U-shaped base form a pitching axis Y axis; and the orientation rotating barrel and the rotating table base form a lower orientation axis Z2 axis. The Z1 axis and the Z2 axis can meet the requirement of whole circle rotation, and the pitching axis Y axis can achieve pitchingrotation in the large range. The pitching axis is provided with a counter weight device balancing the overturning moment so as to balance the overturning moment generated due to pitching, and therefore the driving torque of a pitching axis driving motor can be reduced. The device has the beneficial effects that the bearing capacity is large, a power-off anti-overturning function is achieved, andthe mechanical system reliability is high.

Description

technical field [0001] The invention relates to an attitude adjustment platform, in particular to an attitude adjustment platform used for heavy product testing. Background technique [0002] In the process of testing radar or airborne electronic systems, it is generally necessary to test the working status of products in different attitudes, so devices or equipment that can adjust the attitude of such products are needed. Under large-scale and heavy-load test conditions such as large-scale radars and aircraft avionics systems, not only must the object under test be able to achieve full-circle rotation, but the weight of the device under test is generally relatively large. Traditional hydraulic drive technology has high cost and greatly reduced reliability, cleanliness and maintainability. The prior art is still unable to propose a better electric solution for the large-scale heavy-duty multi-directional attitude adjustment device. Patent 201410587952.8 proposes a large-sc...
