Rapid translation trolley and method of TBM backup trailer

Abstract

The invention provides a rapid translation trolley and method of a TBM backup trailer. The rapid translation trolley comprises a trolley frame which is provided with a driving mechanism and comprisesfour main vertical columns, and both the front rows of main vertical columns and the rear rows of main vertical columns are connected through longitudinal bottom beams correspondingly; a plurality oftransverse rods are mounted above the longitudinal bottom beams, two longitudinal rail beams are mounted on the transverse rods, and backup trailer steel rails are further mounted on the two longitudinal rail beams; and two battery cart tracks are further mounted on the transverse rods, and a plurality of lead screws used for supporting the longitudinal rail beams are inserted in the longitudinalbottom beams in a penetrating mode. The rapid translation method comprises the steps that a translation trolley track is laid; the translation trolley is mounted; backup tracks are connected; a backuptrolley is pushed onto the translation trolley through a battery cart; the translation trolley transversally moves to a designated position; the backup trolley is pushed out through the battery cart;the translation trolley returns back to an original position; and the steps are repeated until all translation tasks are completed. According to the rapid translation trolley and method of the TBM backup trailer, the translation speed of the TBM backup trailer is significantly improved, the construction progress is accelerated, meanwhile, recycling of the translation trolley is realized, and simplification and light-weight are realized.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a fast translational trolley and a method for supporting a trailer behind a BM. Background technique [0002] At present, in the construction of urban subway tunnels, after the shield tunneling machine and TBM (Tunnel Boring Machine, Tunnel Boring Machine) complete the section tunnel construction, frequent translation and empty push are carried out in the station or in the special expansion tunnel. In most cases, the size of the civil works cannot meet the translation requirements of the shield machine and the TBM. It is necessary to separate the shield machine and the TBM for translation. The common translation method for the supporting trolley is to lay cross tracks. By changing the wheel position of the trolley way to realize the translation of the trolley. This method takes a long time to prepare and is inefficient, which greatly restricts the overall...

Problems solved by technology

In most cases, the size of the civil works cannot meet the translation requirements of the shield machine and the TBM. It is necessary to separate the shield machine and the TBM for translation. The common translation method for the supporting trolley is to lay cross tracks. By changing the wheel position of the trolley way to realize the translation of the trolley

This method takes a long time to prepare and is inefficient, which greatly restricts the overall construction progress and increases the construction cost

Moreover, the translation efficiency of the supporting trailer after the TBM seriously restricts the construction period and construction cost
