The external reinforcing ring device comprises an upper reinforcing ring and a lower reinforcing ring which are fixedly connected; the two ends of the upper reinforcing ring and the lower reinforcing ring are respectively in a straight-edge section structure; the inner sides of the straight-edge section structures of the upper reinforcing ring and the lower reinforcing ring are in structures of cutting arcs at the inner sides of the straight-edge sections. The external reinforcing ring device provided by the invention has the advantages that due to treatment on the splicing process of the upper reinforcing ring and the lower reinforcing ring, the problem that the outer container and the external reinforcing rings are welded to exceed the limitation is solved, the residual straight-edge sections in profile rolling are fully utilized, and the utilization rate of materials is increased.
Description
Technical field
The present invention relates to a kind of external stiffening ring device, relate in particular to a kind of external stiffening ring device of outer tank and processing method of low-temperature pressure container.
Background technique
Stiffening ring is conventional in low-temperature pressure container, and a kind of moment of inertia for increasing cylindrical shell, meets the structure that tank body rigidity Design requires, conventionally in tank interior or disposed outside.Stiffening ring is arranged in tank body outside, and for low-temperature (low temperature) vessel, manufacture has a lot of benefits, as being convenient to, vacuumizing and weld, but due to stiffening ring is generally whole coil structures, the low-temperature pressure container outer tank that has gauge for boundary dimension, if still adopt whole coil structures, local boundary dimension is easy to the gauge that is just above standard and requires.
Summary of the invention
In order to solve existing technical problem in background technique, proposed a kind ofly to have can be good at solving super boundary valve problem after whole circle stiffening ring structure and tank body welding, met tank body rigidity requirement, be convenient to manufacturing, and can greatly improve the external stiffening ring device of outer tank and the processing method of low-temperature pressure container of the utilization ratio of material.
Technology settling mode of the present invention is:
The external stiffening ring device of outer tank that the invention provides a kind of low-temperature pressure container, its special way is: comprise stiffening ring and lower stiffening ring; Described upper stiffening ring is fixedly connected with lower stiffening ring; The two ends of described upper stiffening ring, lower stiffening ring are straight section structure; The straight section structure inner side of described upper stiffening ring, lower stiffening ring is straight section inside cutting arc structure;
Above-mentioned upper stiffening ring, lower stiffening ring are nearly semicircle coil structures;
Above-mentioned upper stiffening ring, lower stiffening ring are U-steel, semicircle steel pipe, T bar, angle steel;
The processing method that the invention provides a kind of external stiffening ring of outer tank of low-temperature pressure container, its special way is: comprise the following steps:
1] choose measure-alike U-steel;
2] take the U-steel of choosing, by section bar spheronizator, be rolled onto nearly half circle;
3] by the good semicircle ring recess shaped steel two ends straight section inside cutting circular arc of rolling, and prescind a gap at channel-section steel arc section and the tangent place of straight section, manual bending, makes the circular arc of channel-section steel rolling become arc transition with the inner arc of newly cutting, then straight section and circular arc are cut to the piece welding that opening position forms;
4] two semicircle ring recess shaped steel that cut straight section inner arc are spliced into whole coil structures on tank body;
5] stitching portion is welded;
When above-mentioned steps is also included in the two halves circle U-steel that carries out spliced whole coil structures on tank body, unnecessary straight section is excised.
Advantage of the present invention:
1, the present invention arranges by upper stiffening ring and lower stiffening ring, meets the requirement of standard to the gauge of container boundary dimension, improves the rigidity of stiffening ring to tank body.
2, the present invention is by the processing to upper stiffening ring and lower stiffening ring splicing, solved the problem on the boundary of transfiniting after outer container and external stiffening ring weld, and the unnecessary straight section during section bar rolling making full use of has again improved the utilization ratio of material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein: the upper stiffening ring of 1-, stiffening ring under 2-, 3-straight section, 4-straight section inside cutting circular arc.
Embodiment
The external stiffening ring device of outer tank that the invention provides a kind of low-temperature pressure container, comprises stiffening ring 1 and lower stiffening ring 2; Upper stiffening ring 1 is fixedly connected with lower stiffening ring 2; The two ends of upper stiffening ring 1, lower stiffening ring 2 are straight section 3 structures; The straight section 3 structure inner sides of upper stiffening ring 1, lower stiffening ring 2 are straight section inside cutting circular arc 4 structures.Upper stiffening ring 1, lower stiffening ring 2 are nearly semicircle coil structures; Upper stiffening ring 1, lower stiffening ring 2 are U-steel, semicircle steel pipe, T bar, angle steel;
The processing method that the invention provides a kind of external stiffening ring of outer tank of low-temperature pressure container, comprises the following steps:
1] choose measure-alike U-steel;
2] take the U-steel of choosing, by section bar spheronizator, be rolled onto nearly half circle;
3] by the good semicircle ring recess shaped steel two ends straight section inside cutting circular arc 4 of rolling, and prescind a gap at channel-section steel arc section and the tangent place of straight section 3, manual bending, makes the circular arc of channel-section steel rolling become arc transition with the inner arc of newly cutting, then straight section 3 and circular arc are cut to the piece welding that opening position forms;
4] two semicircle ring recess shaped steel that cut straight section inside cutting circular arc 4 are spliced into whole coil structures on tank body;
5] stitching portion is welded;
When above-mentioned steps is also included in the two halves circle U-steel that carries out spliced whole coil structures on tank body, unnecessary straight section 3 is excised.
Referring to Fig. 1, the present invention is by tank body outer installment stiffening ring outside, and stiffening ring is to be spliced into whole coil structures after half circle by two disconnections and the straight section inside cutting circular arc 4 that carries thereof, each half circle is formed by the rolling of U-steel molded piece, in the process of section bar spheronizator rolling half circle, the two ends of half circle will inevitably leave one section of straight section (needs of section bar spheronizator rolling), the straight section of the structural strengthening circle of general whole circle can adopt the mode of gas cutting to excise, and for the present invention, by to straight section inside cutting circular arc 4 with bend disposal, the part of circle of contact arc has reduced the local height of stiffening ring, just can be for the splicing of the boundary's part that transfinites, both solved the problem on the boundary of transfiniting after the welding of container and external stiffening ring, make full use of again section bar rolling time unnecessary straight section, improved the utilization ratio of material, meet the requirement of standard to container boundary dimension gauge, the present invention is fixedly mounted on tank body and arranges a plurality ofly in addition, makes stiffening ring structure meet tank body rigidity requirement.
