Description
Technical Field
The utility model relates to a shield body segmented welding and fixing tool capable of adjusting height difference, and belongs to the technical field of shield machine shield body manufacturing.
Background
The shield machine is a special engineering machine for tunneling, and in the production process of a shield body of the shield machine, because a shell is large in diameter or super large in diameter, the shield body is very difficult to produce, manufacture and transport, the shield body is generally divided into a front shield part, a middle shield part and a tail shield part to be processed in blocks, and after the processing is finished, the four parts of the shield body are transported to the site and then welded. The shield needs to be positioned and fixed before welding, but due to overlarge size and mass, certain difficulty is generated in positioning and fixing the shield, and the coaxiality of the combined shield cannot be ensured, so that the phenomenon of non-coaxiality can occur after the shield is welded. At present, a method for solving the problem of segmented welding of a shield machine is to weld tooling lifting lugs on the outer surfaces of shield bodies, then lift the two shield bodies by hoisting equipment, and then simply fix and weld the two shield bodies. Because the diameters of the four parts of the shield body are different, the coaxiality of the shield body can be deviated by the positioning method, and the coaxiality after welding cannot be ensured.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a shield body sectional welding fixing tool with adjustable height difference aiming at the defects in the prior art.
In order to solve the technical problem, the utility model provides a shield body segmented welding and fixing tool capable of adjusting height difference, which comprises a tool main body, a sliding block and a bolt, wherein two ends of the tool main body are provided with vertical bends, the middle part of one bent end is provided with a vertical chute, two vertical threaded holes are arranged on the bent end surface and the side wall, and the threaded holes are communicated with the vertical chutes; the slider sets up and can reciprocate in this spout, and the slider passes through three two liang of vertically bolt-up with the frock main part.
Two sides of the bottom of the tool main body and the bottom of the sliding block are provided with 35-degree grooves, and truncated edges with the diameter of 2-5mm are reserved in the middle.
The tool main body is formed by cutting a thick steel plate.
The sliding block is formed by cutting a thick steel plate.
The tool main body and the sliding blocks are uniformly distributed and welded on the whole periphery of the outer side of the shell.
Has the advantages that: the auxiliary welding tool can be used for assembling auxiliary welding tools for the front shield, the rear shield and the tail shield of the shield machine, has a simple structure, is convenient to assemble, can be assembled and welded by the same tool when the diameter difference of the two shells changes, can ensure the coaxiality of the two shells, and solves the problem that the tools cannot be used universally.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1-4, the utility model provides a shield body segmented welding and fixing tool capable of adjusting height difference, which comprises a tool main body 1, a sliding block 2 and a bolt 3, wherein two ends of the tool main body 1 are provided with vertical bends, the middle part of one bent end is provided with a vertical sliding chute, two vertical threaded holes are arranged on the bent end surface and the side wall, and the threaded holes are communicated with the vertical sliding chutes; the slider 2 sets up in the perpendicular spout and can reciprocate, slider 2 and frock main part 1 are through three two liang of vertically bolt 3 fastening.
Two sides of the bottoms of the tool main body 1 and the sliding block 2 are provided with 35-degree grooves, and truncated edges with the diameter of 2-5mm are reserved in the middle of the tool main body and the sliding block, so that the tool and the shell can be conveniently welded, and the welding strength can be effectively enhanced.
The tool body 1 is formed by cutting a thick steel plate.
The slide block 2 is formed by cutting a thick steel plate.
The tool main body 1 and the sliding blocks 2 are uniformly distributed and welded on the whole periphery of the outer side of the shell, and the number of the fixed tools is determined according to the diameter of the shell.
When the height difference of the shell is changed, the height difference between the groove end face of the sliding block and the groove end face of the tool main body can be adjusted to be consistent with the height difference of the two shell radiuses, and the position of the sliding block is fixed through the fastening screw. So that the welding requirement of the current height difference is met.
The tooling needs to be uniformly distributed on the whole periphery of the outer sides of the two shells of the shield body and is connected with the outer sides of the shells in a welding mode, the position of the sliding block needs to be determined according to the diameter difference of the shells, then the position of the sliding block is fixed through a fastening bolt, one end of the tooling is welded on the shells, and the other end of the tooling needs to be welded after the two shells are ensured to be coaxial.
According to the utility model, the height difference of two ends of the tool can be adjusted according to the diameter difference of the shield shell, the slide block and the tool main body are fastened through three-sided bolts, the structure is simple, the assembly is convenient, when the diameter difference of the two shells changes, the same tool can be used for assembly auxiliary welding, and the coaxiality of the two shells can be ensured.
The above-described embodiments of the utility model are intended to be illustrative only and are not intended to be limiting, as all changes that come within the scope of or equivalence to the utility model are intended to be embraced therein.
