Abstract

The invention discloses a limit alarm device for tunnelling in a steel sleeve of a shield tunneling machine. The limit alarm device for tunnelling in the steel sleeve of the shield tunneling machine is characterized in that a connecting pipe is correspondingly arranged on the upper left portion, the upper right portion, the lower left portion and the lower right portion of each steel sleeve and the upper portion and the lower portion of each rear end cover. A probe is connected to one inner side of the steel sleeve to detect the posture of the shield machine in the steel sleeve and the arrivallocation of a cutter head. A detecting pipe is connected to one outer side of the steel sleeve, and an electrical contact pressure alarm is installed on the detecting pipe to detect the pressure in the detecting pipe. A manual ball valve is arranged on an external outlet of the detecting pipe, and is connected with an air pipe to provide air pressure for the detecting pipe. Whether the position of the shield tunneling machine in the steel sleeve is overrun can be monitored in real time, and an alarm can be issued in time when the position is overrun.

Description

technical field [0001] The invention relates to a limit alarm device, in particular to a limit alarm device for tunneling in a steel sleeve of a shield machine. Background technique [0002] Shield machine is a kind of special engineering machinery for tunneling. Modern shield boring machine integrates light, machinery, electricity, hydraulics, sensing and information technology. It has the functions of excavating and cutting soil, conveying soil residue, assembling tunnel lining, Functions such as measurement guidance and deviation correction require extremely high reliability, and have been widely used in tunnel projects such as subways, railways, highways, municipalities, and hydropower. The starting and receiving of the shield machine is an important link in the shield construction. At present, the commonly used construction methods are end reinforcement at the originating end and receiving end and manual removal of the diaphragm wall. However, when there are many und...
