Earth pressure shield machine without a chisel disk

摘要

It is an earth pressure shield machine without a chisel disk is made available. An earth pressure support chamber - separating element comprises a movable earth pressure support chamber - separating element (30) and a solid earth pressure support chamber - separating element (31). A cutter (1) is at the front of a front shield (13) is attached, and comprises cutting heads (11) and cutting teeth (12), which at the cutting heads (11) are distributed. Each cutting head (11) is fixedly connected with one end of a cutter shaft (2), and the other end of the cutter shaft (2) is connected to a force-transmitting device. The force transmission device comprises a power divider (5), a reduction gear (6) and a drive motor (7), wherein said reduction gear (6) and the drive motor (7) with the power divider (5) are connected. The front end of the transfer case (5) in the case of the force-transmitting device in the upper half portion of the shield machine is connected to the movable separating element (30) of the earth pressure support chamber fixed. The reduction gear (6) and the drive motor (7) which, with the distributor gear unit (5) are connected, are supported by a sliding device, and the rear side of the sliding device is provided with a retractable cylinder (26) connected. The earth pressure shield machine without a chisel disk has the advantages of a high cutting performance capability, a balanced service life, a high direction and can be a high adaptability to the cross sections of tunnels on.
