Embodiment Construction

[0027] see Figure 1-Figure 4 , the present invention is a kind of dregs conveying method applied to double-shield tunnel boring machine,

[0028] Include the following steps:

[0029] (1) Use the main belt conveyor 2 to transfer the excavated cutter head 1 to the second belt conveyor 3;

[0030] (2) The second belt conveyor 3 transports the ballast to the fabric belt conveyor 4;

[0031] (3) The distribution belt conveyor 4 distributes the ballast into different compartments of the ballast truck 5 by moving back and forth along the track 7 and switching the direction of rotation.

[0032] The whole slag removal system that the present invention adopts comprises main belt conveyor 2, second belt conveyor 3, slag transport vehicle 5 and trolley 10, and the tail end of main belt conveyor 2 is corresponding to the head end of second belt conveyor 3, and the second belt conveyor 3 Belt conveyor 3 is installed on the top of n-shaped trolley 10, and trolley track is provided belo...

Abstract

A method and device for conveying dregs applied to a double-shield tunnel boring machine, comprising the following steps: (1) using the main belt conveyor to transfer the dregs excavated by the cutter head to the second belt conveyor; (2) the second belt conveyor (3) The material belt conveyor distributes the ballast into different compartments of the ballast truck by reciprocating along the track and changing the direction of rotation. The advantages of the present invention are: through the two-way movement of the shuttle belt conveyor, the shuttle belt conveyor can be loaded with four ballast trucks from the original loading of two ballast cars, which greatly improves the efficiency of ballast removal; and through The self-tensioning device makes the fabric belt conveyor easier to maintain and less labor-intensive.

Description

technical field [0001] The invention relates to a method and device for discharging and conveying ballast applied to a double-shield tunnel boring machine, which are used for transporting the ballast out of the tunnel and ensuring the high efficiency of TBM tunnel construction. Background technique [0002] Double-shield TBM can realize the continuous operation of hard rock tunnel excavation, ballast removal and support. Because of its safe, efficient and reliable performance, it has been widely used in water conservancy and hydropower, mining, rail transit, municipal administration, national defense, etc. project. Its host is composed of four parts: front shield, retractable shield, support shield and tail shield. The transportation of muck is an extremely important part of TBM, and the efficiency of muck removal is closely related to the efficiency of feeding. Therefore, a reliable and efficient ballasting system is very important for TBM. Due to the fast excavation spe...
