Shield top is provided with the groove passed through for main frame belt feeder；
Interior triumphant afterbody is sequentially installed with driving box, reductor, motor, and reductor is connected with motor, reductor and drive
Dynamic case connection, power transmission shaft are arranged on interior triumphant inside, and power transmission shaft front end is connected with adapter ring, rear end and driving box connect.
Described outer triumphant on support boots are installed, outer triumphant be provided with oil cylinder with support boots；Triumphant outward be connected with propelling cylinder one end, interior triumphant
It is connected with the propelling cylinder other end.
Advantages of the present invention：Interior triumphant afterbody is placed in after motor, reductor and driving box, can reduce shield length,
Supporting is carried out to country rock in time, while moving after making the center of gravity of main frame, is conducive to stablizing for main frame, prevent TBM from planting head.
Power transmission shaft is located at interior Kerry face, and main frame belt feeder is placed in outer triumphant top, by this arrangement, can reduce inside and outside triumphant
Size, increase host region working space, TBM structures can be caused compacter, with adapt to excavate minor diameter hard rock tunnel
The requirement in road.
