Embodiment Construction

[0048] In conjunction with the accompanying drawings, the present invention is described in detail, but the scope of protection of the present invention is not limited to the following examples, that is, all simple equivalent changes and modifications made with the patent scope of the present invention and the content of the specification are still patents of the present invention. covered.

[0049] Depend on figure 1 It can be seen that the space inside the tunnel is narrow during the construction of the shield machine. For a tunnel of 5500mm, the diameter of the main bearing of the shield machine assembly machine can reach 3200mm, so there is not enough space for replacement underground. In view of this, the concrete implementation technical scheme of the present invention is as follows:

[0050] 1. Complete the preparations required before the hoisting trolley and bearing transport vehicle enter the site:

[0051] 1.1 remove the tablet feeder 205;

[0052] 1.2 Complete t...

Abstract

The invention discloses a method for underground replacement of an erector main bearing of a shield tunneling machine. The method comprises the following steps: firstly transporting the bulk parts of a hoisting trolley to a crane span structure, mounting a bearing hoisting tool and a new erector main bearing and conveying to the front part of the crane span structure, and fixedly connecting the front part of the crane span structure with a vertical support of a bearing transportation vehicle; dismantling all pipes and moving the crane span structure backwards; assembling the hoisting trolley and dismounting an erector main bearing mounting seat and a damaged erector main bearing connection bolt; hoisting the damaged erector main bearing by using the hoisting trolley and dismounting an erector rotation ring and the damaged erector main bearing connection bolt; hoisting a new erector main bearing to be assembled with the erector rotation ring, and hoisting the erector main bearing mounting seat to assemble with the main bearing; finally recovering the damaged bearing and connecting the pipes. The method for underground replacement of the erector main bearing of the shield tunneling machine is capable of avoiding silo digging on ground, so that lots of of construction is eliminated, the project progress is greatly improved, and the project expense is reduced.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to an underground replacement method for a main bearing of a shield machine assembly machine. Background technique [0002] Shield tunnel boring machine, referred to as shield machine, is a special construction machine for tunnel boring. It is widely used in various tunnel projects such as subway tunnels, railway tunnels, water diversion tunnels, highway tunnels, mine roadways, and urban municipal tunnels. The shield tunneling method has the advantages of high degree of automation, labor saving, fast construction progress, one-time hole formation, and no climate influence. Especially when the geology is complex, the groundwater level is high and the tunnel depth is large, the shield machine can only be relied on. Therefore, it is widely used in tunnel construction. [0003] During shield tunneling construction, because the shield tunneling machine is buried deep undergroun...
