Description
Technical Field
The utility model relates to a shield machine hob replacing technology, in particular to a shield edge hob mounting device.
Background
In the field of underground engineering, the application of shield construction is more and more extensive, and particularly in the construction of subway tunnels, the advantages of shield construction are particularly obvious. The edge hob cutter is one of key parts on the shield machine and directly undertakes the task of excavating the tunnel face. When the edge hob cutter is damaged in the tunneling process of the shield tunneling machine, the cutter needs to be replaced by entering a bin, and the cutter can be replaced only at 9 points of a cutter disc of the shield tunneling machine due to the fact that the edge hob is inclined in angle and higher in installation height under the ordinary condition.
But the cutter can not be replaced at the 9-point position due to some accidents; for example: changing the cutter under pressure, wherein the stratum is weak, and the liquid level needs to be kept high; or the stratum at the 9-point position is out of the field and collapses, so that the replacement risk is high, at the moment, the stratum can be replaced only at the 12-point position of the cutter head, but the 12-point position is very inconvenient to replace, and the stratum can hardly be replaced by manpower.
