Abstract
The invention discloses a technique for integrally manufacturing a semi-structure of a full-face tunneling machine shield applied to the field of a full-face tunneling machine. A front shield is separated into a left half body, a right half body and a lower half body, wherein three pairs of coupling flanges are arranged; the coupling flanges are firstly processed and then each pair of flanges is closed by a process bolt to be as a combined element to be welded into a whole together with each half body; in order to prevent a flange surface from separating to generate a crack and deformation during overall heat treatment, a dense steel plate tie bar is welded to connect on a seam of inner and outer shell plates; the steel plate tie bar is cut off, polished and repaired after thermal treatment according to the processing situation so as to ensure the shield achieves the shape tolerance requirements. According to the technique, the defects of the conventional technique for manufacturing the shield of the semi-structure can be overcome; the coupling flanges are processed one by one, and two flanges are merged into a whole and welded with the steel plate on the shield by the process bolt, so that the problems that the welding is easy to deform are solved, the excircle geometrical tolerance is difficultly ensured, the processing cost is high, the processing difficulty of the flange is large and each half body is difficultly closed.
Description
Technical field
The present invention relates to the process that a kind of full face tunnel boring machine shield body in the full face tunnel boring machine field divides half hitch structure integral manufacturing.
Background technology
In the full face tunnel boring machine field, construct, transport reason to different-diameter and consideration, development machine shield body requires to adopt the full face tunnel boring machine of branch half hitch structure; The traditional preparation method of its shield body is: weld each halfbody earlier; Reprocessed flange, closed with the bolt handle at last, the shortcoming of this kind method is: weld yielding; Difficulty of processing is big, long in time limit, and the cylindrical form and position tolerance is difficult to guarantee.Like two shield hard rock moles; Consider the accident that transportation clearance and in-cavity construction possibly occur; Require the shield body to adopt and divide the half hitch structure, because shield shape tolerance is very tight, traditional process exists welding yielding; Difficulty of processing is big, cost is high, long in time limit, the cylindrical form and position tolerance such as is difficult to guarantee at a lot of defectives.Therefore developing a kind of full face tunnel boring machine shield body, to divide the process of half hitch structure integral manufacturing be to be badly in need of the new problem that solves.
Summary of the invention
The object of the invention just provides the process that a kind of full face tunnel boring machine shield body divides half hitch structure integral manufacturing, overcomes the traditional handicraft method and makes the defective that the shield body of branch half hitch structure brings, first single-piece work coupling flange; With service bolt two flanges are welded the steel plate on integrator and the shield body again; It is yielding to solve welding, and the cylindrical form and position tolerance is difficult to guarantee that processing cost is high; Processing flange difficulty is big, and each halfbody is closing difficult problem.
The objective of the invention is to realize like this: the process that a kind of full face tunnel boring machine shield body divides half hitch structure integral manufacturing; The anterior shield body is divided into left halfbody, right halfbody and lower semi-body three parts; Coupling flange has three pairs; First processing coupling flange gets togather every pair of flange handle with service bolt again, is welded into integral body as sub-assembly and each halfbody; During bulk heat treatmet, produce the distortion of cracking for preventing that flange face from throwing off, at inside and outside coverboard seam crossing, weld closely knit steel plate lacing wire and connect, after the heat treatment, again according to the processing situation, cut off the steel plate lacing wire, polishing is repaired; The operation principle of said process is, first single-piece work coupling flange, again with service bolt with two flanges integrator, as the welding of the steel plate on sub-assembly and the shield body, it is yielding to solve welding, processing flange difficulty is big, each halfbody is closing difficult problem; Simultaneously, during the bulk heat treatmet of shield body, produce the distortion of cracking for preventing that flange face from throwing off, at inside and outside coverboard seam crossing; The lacing wire of welding steel plate connects, to be heated after, again according to the processing situation; Cut off lacing wire, polishing is repaired, and guarantees that the shield body reaches the process that form tolerance requires.
Main points of the present invention are its process and operation principle.Its operation principle is, first single-piece work coupling flange, again with service bolt with two flanges integrator, as the welding of the steel plate on sub-assembly and the shield body, it is yielding to solve welding, processing flange difficulty is big, each halfbody is closing difficult problem; Simultaneously, during the bulk heat treatmet of shield body, produce the distortion of cracking for preventing that flange face from throwing off, at inside and outside coverboard seam crossing; The lacing wire of welding steel plate connects, to be heated after, again according to the processing situation; Cut off lacing wire, polishing is repaired, and guarantees that the shield body reaches the process that form tolerance requires.
The process that full face tunnel boring machine shield body divides half hitch structure integral manufacturing compared with prior art has and overcomes the traditional handicraft method and make the defective that the shield body that divides the half hitch structure brings, first single-piece work coupling flange; With service bolt two flanges are welded the steel plate on integrator and the shield body, the solution welding is yielding again, and the cylindrical form and position tolerance is difficult to guarantee; Processing cost is high; Processing flange difficulty is big, and each halfbody handle closes advantages such as difficult problem, will be widely used in the full face tunnel boring machine field.
