Segment conveying trolley adapting to full ring segment conveying and small curve excavation functions at the same time

Abstract

The invention discloses a tube segment transport trolley simultaneously adaptive to a whole-ring tube segment transportation function and a small-curve tunneling function. The tube segment transport trolley comprises a connecting base and a trolley body, wherein the connecting base is connected with the trolley body through a lever pulley block and a guide chain; the trolley body further comprises at least two racks which are connected; rack supporting wheels are arranged on the head and tail lower parts of each rack, a slide bracket and a lifting bracket are arranged on the upper part of each rack; the lifting brackets are arranged in series, and the sliding brackets are connected in series; the sliding bracket at the foremost end extends out of the rack at the foremost end, and a supporting wheel is arranged on the lower part of the sliding bracket at the foremost end. The length of the tube segment transport trolley disclosed by the invention can be more than 20 meters according to the tube segment diameter, the tube segment segmentation and the whole equipment arrangement; the transportation efficiency is not affected when the tube segment transport trolley is used for synchronously transporting the whole-ring tube segments at a relatively long distance, and the trolley travelling function is not affected on the condition of meeting small-curve tunneling turning.

Description

technical field [0001] The invention belongs to the field of tunnel shield construction, and mainly relates to a segment conveying device used in conjunction with a segment assembly machine in the process of tunnel excavation, in particular to a tube that can simultaneously satisfy the functions of whole ring segment conveying and small curve shield tunneling. Sheet conveying trolley. Background technique [0002] As tunneling equipment such as shield tunneling or TBM is more and more widely used in underground tunnel engineering, the engineering requirements for equipment use are also getting higher and higher. In many tunnel engineering processes, it is necessary to have a convenient and fast temporary retreat function. Therefore, the supporting arrangement in which the rear of the shield or TBM main engine needs to be connected to the trolley instead of directly connecting to the bridge frame is more conducive to the structural layout of the whole machine, and can facili...

AI Technical Summary

Problems solved by technology

The existing shield supporting segments do not have the functions of transporting trolleys to meet the needs of long-distance walking in the tunnel, segment transportation, and adapting to small-radius curve excavation.
