Summary of the invention
The present invention proposes a kind of centre revolving joint that can be used for multi-mode shield machine, solves shield machine swivel coupling in prior art and is not suitable for the problem with muddy water, the convenient conversion of soil pressure pattern.
Technological scheme of the present invention is achieved in that a kind of centre revolving joint that can be used for multi-mode shield machine, comprise rotor and be arranged on the stator outside rotor, rotor one end is connected with connecting base, connecting base is connected with flange plate, stator sidewall is provided with modifying agent inlet, modifying agent channel connection in modifying agent inlet and rotor, the modifying agent passage the other end is communicated with the vertical passage in flange plate, vertical passage and modifying agent pipeline communication; Stator sidewall is also provided with fluid passage entrance, fluid passage entrance is communicated with the fluid passage in rotor, fluid passage is communicated with flange plate, rotor center is provided with mud and washes away passage, mud washes away passage end and washes away entrance with the mud on connecting base and be communicated with, and mud washes away the passage the other end and is communicated with mud flush pipe.
Described modifying agent pipeline and mud flush pipe are four.
Described fluid passage entrance is four.
Stamping Steel Ribbon is provided with between described stators and rotators.
Connecting base is provided with boss, and flange plate is provided with the groove of coupling boss, and connecting base is connected with rotor welding, and connecting base and flange plate are bolted.
The present invention, when for EPB shield tunneling or slurry shield, does not need to change centre revolving joint, only needs connect and open respective channel pipeline, just can meet use needs, thus reduce manufacture cost and manufacturing cycle.Structure of the present invention is simple, easy to operate, economical and practical.
