A wheel bracket device used for a shield machine comprises at least two brackets, a liftable roller mechanism and a rotating mechanism, wherein, the brackets are used for bearing the shield machine; the roller mechanism is mounted at the pivot points of the brackets and used for bearing the shield machine in an ancillary manner; and the rotating mechanism is mounted on the shield machine and used for towing the shield machine to rotate. As the wheel bracket device structure of the shield machine adopts the rotating mechanism and the roller mechanism, and a dedicated roller mechanism is added on the bearing pivot points of the shield machine skillfully on the basis of the prior shield machine, the shield machine can rotate to an optional angle freely according to the requirements through the device, and all that an on-site worker needs to do is to conduct assembly and welding on one side of the shield machine. Therefore, the device has the advantages that the difficulty in welding is greatly reduced; the safety of the worker during operation is ensured; the welding quality can be also improved; and the device plays a threefold role. Moreover, the utility model further has the advantages of simple structure, easy realization and high practicability.
