Abstract

The invention discloses a double-mode shield screw machine mode switching device and a using method thereof. The double-mode shield screw machine mode switching device comprises a connecting rotatingmechanism and lifting mechanisms, the connecting rotating mechanism is arranged on the front part of a screw conveyor, and the screw conveyor is detachably connected with a main drive or a front shield screw machine base through the connecting rotating mechanism; the lifting mechanisms are symmetrically arranged on both sides of the screw conveyor, and the outer side of the lifting mechanism is fixedly connected with a main beam of an assembling machine, and the inner side of the lifting mechanism is slidably connected with the screw conveyor. The double-mode shield screw machine mode switching device can not only meet construction requirements of advancing in an open mode and in an earth pressure mode, but also assist to complete fast and efficient mode conversion, the installation mode is simple, convenient and fast, the efficient and collateral operation mode of a main machine and back-up equipment is realized, construction efficiency of a shield machine is improved, and adaptability of the shield machine is enhanced.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling machine construction, and in particular relates to a dual-mode shield tunneling screw machine mode switching device and a use method. Background technique [0002] At present, the 6m-level central screw type earth pressure / open dual-mode shield (earth pressure mode for slag discharge by the bottom screw machine + open mode for slag discharge by the central screw machine) is used in geological It has begun to be applied in urban subway tunnels with complex and changeable environments. How to quickly and efficiently complete the mode conversion is the key factor for the smooth construction of the 6m-level dual-mode shield. However, the construction method of its high-efficiency mode conversion has not been studied at home and abroad. [0003] Limited by the space of the main engine, the central screw machine and the bottom screw machine required for the two modes of excavation and slag dis...
