Abstract

The invention discloses a broken shaft quick coupling for a shield screw machine and a method. The quick coupling includes a coupling main body, wherein plugs are convexly arranged at the two ends ofthe coupling main body; the plugs are matched with a center shaft hole of a middle shaft of the screw machine. The broken shaft quick coupling has the following beneficial effects: stability of a shield soil bin is guaranteed, and safety problems of water bursting, sand bursting, and the like, of the shield screw machine, appearing during repairing can be solved; through arranging the broken shaftquick coupling for the shield screw machine at a broken shaft, the broken shaft can be repaired simply, quickly and conveniently, the service life and repairing quality can be improved, the continuity and stability for tunneling of a shield tunneling machine are guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of repairing a broken shaft of a shield screw machine, in particular to a quick joint and a method for repairing a broken shaft of a shield screw machine. Background technique [0002] The construction technology of shield machine has a history of several decades in China, and it has become more and more mature after nearly ten years of rapid development. Domestic shield construction is becoming more and more specialized. In the face of various strata in various cities, the pressure on the shield screw machine is also different. However, in the construction of shield tunnels in rich water and boulder strata, a large amount of boulders will accumulate in the soil warehouse. , boulders will wear the central axis of the screw machine of the shield screw machine, which is prone to shaft breakage and affects normal work and production. [0003] According to the survey on the use of domestic rail transit shield s...
