Problems solved by technology

[0002] In the existing technology, due to the development of technology, the construction volume of road tunnels and railway tunnels is constantly increasing, which brings about a surge in the number of tunnel steel arch frames processed, and the existing processing methods and devices can no longer meet their processing and installation requirements. The requirements for precision lead to a low qualified rate of steel arch installation and a long time required for the installation of the arch, which seriously affects the engineering quality and construction progress of the initial support of the tunnel; at the same time, during the construction of the tunnel steel arch, if the steel arch There are quality defects in the processing of the arch frame, which will pose a great safety hazard
[0003] The reasons for the above problems are that one is the large amount of processing of the steel arch; the other is the special structure of the steel arch itself, which has curved radians during use and processing, so whether it is in the arch When welding with the connecting steel plate, there will be a circumferential and longitudinal misalignment, or when the raw material is carefully pre-cut, it will be due to the influence of its radian, which will lead to the angle problem of the steel arch connecting the steel plate, which greatly affects the steel arch. processing quality and efficiency

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0032] The tunnel steel arch processing limit device of the present invention is to figure 1 The bent I-beam shown and the connecting steel plate connected to the end of the I-beam are processed to limit the processing efficiency and quality of the steel arch, and provide standardized limitations and measurement basis for standardized construction on site.

[0033] Such as figure 2 with image 3 As shown, it includes a welding limit mold; the welding limit mold includes a positioning beam 1, a limit clamping plate 2 symmetrically and vertically arranged on the lower surface of both ends of the positioning beam 1, and a welding positioning plate arranged at the front end of the limit clamping plate 1 3. Two limit clamps 2 are arranged face to face in parallel, the distance between them is e...

Abstract

The invention relates to large-scale tunnel steel arch machining, in particular to a tunnel steel arch machining limiting device and method. The tunnel steel arch machining limiting device comprises awelding limiting mould; the welding limiting mould comprises a positioning cross beam, limiting clamping plates which are symmetrically and vertically arranged on the lower surfaces of the two ends of the positioning cross beam and welding positioning plates which are arranged on the front ends of the limiting clamping plates; the two limiting clamping plate are arranged oppositely and parallelly, and the distance between the two limiting clamping plate is the same as the width of a wing edge of steel arch joist steel; the length of each limiting clamping plate is greater than the height of the steel arch joist steel; the upper ends of the welding positioning plates are fixedly connected to the lower surface of the positioning cross beam, and the inner side of each welding positioning plate is vertically connected to the front end of the corresponding limiting clamping plate; two positioning posts are separately arranged on the front surface of each welding positioning plate; and thepositions of the four positioning posts are the same as those of connection through holes in a steel arch connection steel plate. The tunnel steel arch machining limiting device is simple in structure, reasonable in design and convenient to use; the machining efficiency and the production qualification rate of arches can be greatly improved; and a practical and feasible device and method is provided for large-scale on-site production.

Description

technical field [0001] The invention relates to the processing of large quantities of tunnel steel arches, in particular to a processing limiting device and method for tunnel steel arches. Background technique [0002] In the existing technology, due to the development of technology, the construction volume of road tunnels and railway tunnels is constantly increasing, resulting in a sharp increase in the number of tunnel steel arch frames processed, and the existing processing methods and devices can no longer meet their processing and installation requirements. The requirements for precision lead to a low qualified rate of steel arch installation, and a long time is required for the installation of the arch, which seriously affects the engineering quality and construction progress of the initial support of the tunnel; at the same time, during the construction of the tunnel steel arch, if the steel arch There are quality defects in the processing of the arch frame, which wil...
