Block type shield tunneling machine factory assembly method

Abstract

The invention relates to the technical field of shield tunneling machine manufacturing, in particular to a block type shield tunneling machine factory assembly method. The method comprises the following steps that a, a main machine station support is arranged; b, a front shield is divided into a plurality of blocks, and a front shield bottom block is first loaded on a station; c, a middle shield is divided into a front part and a rear part, then the front part of the middle shield is re-divided into a plurality of blocks, firstly, a middle shield front lower block is loaded on the station, andthe front shield bottom block is in hard connection with the middle shield front lower block; d, a main drive is loaded on the station; e, front shield remaining blocks are loaded on the station oneby one and are assembled with the adjacent blocks; f, middle shield remaining blocks are loaded on the station one by one; g, a whole middle shield rear part and a propulsion oil cylinder are sequentially loaded on the station; h, a tail shield is divided into a plurality of blocks, and a tail shield lower block is firstly loaded on the station; and i, tail shield remaining blocks are loaded on the station one by one. According to the method, shield station assembly is free of dependence on hoisting equipment, hoisting and turnover are more convenient, the safety performance is greatly improved through a reasonable assembly sequence, and the assembly difficulty of a block type shield tunneling machine is reduced.

Description

technical field [0001] The invention relates to the technical field of shield machine manufacturing, in particular to a factory assembly method of a block type shield machine. Background technique [0002] With the continuous change of the shield construction method, the 6-7m level shield machine is gradually adopting the block form. The 6-7m block type shield body has not been assembled in the factory, and there is difficulty in assembly. The main difficulty is reflected in If the block-type host is assembled in the wrong order, the assembly will be more difficult, or the assembly risk will be greater, or even the installation will not be successful. Therefore, if there is no reasonable assembly plan, the probability of safety and quality problems in the later stage will increase accordingly. [0003] According to the previous shield machine assembly method, the shield body is first assembled as a whole, and then the overall hoisting is carried out for station assembly. Ho...

[0002] With the continuous change of the shield construction method, the 6-7m level shield machine is gradually adopting the block form. The 6-7m block type shield body has not been assembled in the factory, and there is difficulty in assembly. The main difficulty is reflected in If the assembly sequence of the block-type host is wrong, the assembly will be more difficult, or the assembly risk will be greater, or even the installation will not be successful

Therefore, if there is no reasonable assembly plan, the chances of safety and quality problems will increase accordingly

[0003] According to the previous shield machine assembly method, the shield body is first assembled as a whole, and then the overall hoisting is carried out for station assembly. However, due to the limitations of hoisting and driving capacity in each workshop, it is unable to meet the overall requirements of the 6-7 meter shield machine. Situation of hoisting
