Abstract
The utility model provides an external reinforcing ring for an outer tank of a low temperature pressure vessel. The external reinforcing ring comprises an upper reinforcing ring, a lower reinforcing ring and connecting assemblies arranged in the connecting positions of two ends of each of the upper reinforcing ring and the lower reinforcing ring respectively; the connecting assemblies comprise a first connecting piece and a second connecting piece, and the first connecting piece is fixedly connected with one end of the upper reinforcing ring and one end of the lower reinforcing ring; and the second connecting piece is fixedly connected with the other end of the upper reinforcing ring and the other end of the lower reinforcing ring. According to the external reinforcing ring, the problem of ultralimit after welding of the whole reinforcing ring structure and a tank body is solved, the rigidity of the tank body can be effectively enhanced, and the assembly difficulty of the reinforcing ring and the vessel is greatly reduced.
Description
Technical field
The utility model belongs to the tank body field of low-temperature (low temperature) vessel, relates to a kind of outer tank stiffening ring, relates in particular to a kind of external stiffening ring of low-temperature pressure container outer tank.
Background technique
The external stiffening ring of outer tank is that in low-temperature pressure container, outer tank is arranged a kind of conventional structure of stiffening ring, but there is the low-temperature pressure container of 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, if adopt two semicircles to be spliced into whole coil structures with the stiffening ring of straight flange end, straight section inside portion is cut circular arc and is met gauge requirement to reach, and has greatly increased assembling difficulty; Therefore, be badly in need of a kind ofly can be good at solving the problem on boundary that transfinites after whole circle stiffening ring structure and tank body welding, and can have effectively increased the rigidity of tank body, greatly reduce the external stiffening ring of the assembling difficulty of stiffening ring and container.
Summary of the invention
In order to solve existing technical problem in background technique, the utility model proposes a kind of external stiffening ring of low-temperature pressure container outer tank.
Technology settling mode of the present utility model is:
The utility model provides a kind of external stiffening ring of low-temperature pressure container outer tank, and its special way is: comprise stiffening ring, lower stiffening ring and be separately positioned on stiffening ring and the link assembly of joint, lower stiffening ring two ends;
Described link assembly comprises the first link and the second link; Described the first link is fixedly connected with upper stiffening ring one end, lower stiffening ring one end; Described the second link is fixedly connected with the upper stiffening ring the other end, the lower stiffening ring the other end;
Above-mentioned the first link comprises grooved part and is fixedly installed on respectively the closure plate at grooved part two ends; Described the second connecting-piece structure is identical with the first connecting-piece structure;
Above-mentioned upper stiffening ring and lower stiffening ring are nearly semicircle coil structures;
Above-mentioned upper stiffening ring and lower stiffening ring are U-steel, semicircle steel pipe, T bar, angle steel.
Advantage of the present utility model:
1, the utility model, by adopting being used in conjunction with of stiffening ring and link, has solved the problem that boundary dimension transfinites, and has increased the effective moment of inertia of this position tank body, has improved the local stiffness of tank body;
2, the utility model is by adopting being used in conjunction with of stiffening ring and link, and the mode that use segmentation is fixedly connected with tank body greatly reduces the assembling difficulty of stiffening ring, link and tank body;
3, size of components of the present utility model is little, and has existing processing technique to be supported, is easy to processing and controlled working precision.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is connecting-piece structure schematic diagram of the present utility model;
Wherein: the upper stiffening ring of 1-, stiffening ring under 2-, 3-the first link, 4-the second link, 5-grooved part, 6-closure plate.
Embodiment
The utility model provides a kind of external stiffening ring of low-temperature pressure container outer tank, comprises stiffening ring 1, lower stiffening ring 2 and is separately positioned on stiffening ring 1 and the link assembly of lower stiffening ring 2 joints, two ends;
Link assembly comprises the first link 3 and the second link 4; The first link 3 is fixedly connected with upper stiffening ring 1 one end, lower stiffening ring 2 one end; The second link 4 is fixedly connected with upper stiffening ring 1 the other end, lower stiffening ring 2 the other ends;
The first link 3 comprises grooved part 5 and is fixedly installed on respectively the closure plate 6 at grooved part 5 two ends; It is identical that the second link 4 structures and first connect 3 structures;
Upper stiffening ring 1 and lower stiffening ring 2 are nearly semicircle coil structures;
Upper stiffening ring 1 and lower stiffening ring 2 are U-steel, semicircle steel pipe, T bar, angle steel.
The outer tank cylindrical shell stiffening ring of the low-temperature (low temperature) vessel shown in Fig. 1 is made up of two nearly semicircle stiffening rings and two links; Link shown in Fig. 2 is made up of a grooved part 5 and two closure plates 6; By reducing the height of link, solve the problem that boundary dimension transfinites, by increasing the width of link, increased the effective moment of inertia of this position cylindrical shell simultaneously, increase the local stiffness of tank body.
While assembling the external stiffening ring of cylindrical shell, first carry out the assembly welding of two nearly semicircle stiffening rings and outer tank cylindrical shell, carry out again the welding between link and nearly semicircle stiffening ring, because link size is less, easily controlled working precision, so that the height in gauge direction is easy to is controlled, is connected because nearly semicircle stiffening ring belongs to fillet welding with link simultaneously, assembling precision is less demanding, and these all greatly reduce the assembling difficulty of stiffening ring and tank body.
The utility model has well solved the problem on boundary that transfinites after whole circle stiffening ring structure and tank body welding, and can greatly reduce the assembling difficulty of stiffening ring and container, has increased the local stiffness of tank body simultaneously.
This low-temperature (low temperature) vessel outer tank stiffening device comprises the stiffening ring that is arranged on outer tank external body, this stiffening ring is to be welded into whole coil structures by nearly half circle of two disconnections and two links, meet the requirement of standard to container boundary dimension, and greatly reduce stiffening ring and tank body between assembling difficulty, can greatly increase the local stiffness of this place's tank body by changing the width dimensions of link simultaneously.
