Stepping platform enabling shield machine/TBM to rapidly pass station

Abstract

A stepping platform enabling a shield machine / TBM to rapidly pass a station comprises a shield body, a hydraulic system and an electrical system. A plurality of limiting blocks and lifting frames are welded to the two sides of the bottom of the shield body. The lifting frames are connected with return oil cylinders and lifting oil cylinders through oil cylinder pins. A flat base sliding frame is arranged at the bottom of the shield body. A locating guide wheel is arranged at the bottom of the flat base sliding frame. Pushing oil cylinders are arranged on the flat base sliding frame. One end of each pushing oil cylinder is provided with a pushing oil cylinder fixture block. The pushing oil cylinder fixture blocks are fixed to a back seat through bolts. Another locating guide wheel is arranged at the bottom of the back seat. The stepping platform improves the stepping speed of the shield machine and reduces the manpower needed by stepping of the shield machine. Full-hydraulic transposition stepping is applied to the stepping platform, so that automatic operation of stepping of the shield machine is achieved, and the safety of stepping of the shield machine is improved.

Description

Technical field: [0001] The invention belongs to the field of tunnel construction, in particular to a stepping platform that realizes the rapid passage of the shield machine through empty pushing through the relative movement of the shield body of the shield machine / TBM and the platform system. Background technique: [0002] At present, the traditional shield / TBM pass station is to drill holes on the track to install the reaction force support. The shield machine is moved forward through the shield / TBM propulsion cylinder to support the reaction force support, and then the reaction force support is moved forward for the next cycle. ; Every time the shield moves a cycle, it needs to reverse the track once, and each process delays a lot of time. The shield passing through the station is relatively slow and there are certain safety hazards. Invention content: [0003] In order to solve the above-mentioned problems, the present invention provides a stepping platform for shield...
