Description

Universal rotating mechanism and AGV trolley using same

Technical Field

The utility model belongs to the field of universal rotating mechanisms and an AGV (automatic guided vehicle) using the same.

Background

The wheel pair is the part of the rolling stock contacted with the steel rail and is formed by firmly pressing the left wheel and the right wheel on the same axle. The wheel set has the functions of ensuring the running and steering of the rolling stock on the steel rail, bearing all static and dynamic loads from the rolling stock, transmitting the static and dynamic loads to the steel rail and transmitting the loads generated by unsmooth lines to all parts of the rolling stock.

The bogie is one of the most important parts in the structure of a railway vehicle and mainly comprises two wheel pairs arranged in a front-to-back manner and a fixing frame for connecting the two wheel pairs.

In the maintenance and treatment process of the wheel set or the bogie, the wheel set or the bogie needs to be moved at different treatment stations, so that different treatments of the wheel set or the bogie are realized. When the wheel set or truck is moving, the wheel set or truck needs to be pulled by the AGV trolley because the wheel set or truck itself is not powered. In some repair workshops where multiple processes are performed, the AGV needs to perform multiple steering and straight traveling operations because of the complex structure in the repair workshops, so that the wheel set or the bogie can be ensured to accurately move to a predetermined position.

However, the driving mechanism of the existing AGV usually has only a straight running function, and can not meet the use requirement in a complex maintenance workshop. Therefore, in order to enable the AGV cart to rotate, a steering mechanism needs to be installed in the AGV cart.
