Abstract
The utility model provides a connecting structure of a pressure vessel and legs. The connecting structure comprises a bottom seal head of the pressure vessel, a backing board adhered to the bottom seal head and provided with a through hole in the center, and the legs penetrating the through hole to be welded on the bottom seal head and the backing board. Owing to the structure, as the legs are directly connected to the bottom seal head, the connecting strength between the legs and the bottom seal head is increased, and accordingly, the legs and the bottom seal head are not easy to crack and high in safety.
Description
Technical field
The utility model relates to a kind of linkage structure, especially the linkage structure of the bottom (head) of vertical pressure vessel and supporting leg.
Background technique
Supporting leg is unusual part and parcel in design of pressure vessels, and most vertical fixed containers need be installed supporting leg.In structure aspects several relevant criterion are arranged: mechanical industry standard has JB/T4712.4-2007 " vessel base the 4th part prop support ", European norm EN13445-3 " unfired pressure vessel design ".The pattern feature of the prop leg of the band backing plate of these standard codes all is backing plate and outer end socket applying, and backing plate is solid, and supporting leg directly is connected with backing plate, to reach the purpose of supporting container.The problem that the linkage structure of this pressurized container and supporting leg exists is: the join strength of supporting leg, backing plate and bottom (head) is lower, in use be subjected to the time spent of doing of the wind load of substantially horizontal or earthquake loading when container, supporting leg is higher and be easy to cracking in the localized stress at support zone place, thereby the safety in utilization of pressurized container reduces.
The model utility content
The utility model is to solve in the prior art, the technical problem that the linkage structure join strength of pressurized container and supporting leg is low, be easy to when using to ftracture, Security is low.
The utility model provides the linkage structure of a kind of pressurized container and supporting leg, comprise pressurized container bottom (head), be attached at bottom (head) and middle backing plate with a through hole, pass through hole and be welded in the supporting leg of bottom (head) and backing plate.Because supporting leg directly is connected with bottom (head), make join strength between the two increase, be not easy to cracking, safe like this.
In one embodiment, bottom (head) and backing plate have corresponding arcuate surface, and the outer periphery fillet welding of backing plate is connected to the surface of bottom (head).
In one embodiment, through hole exposes the part surface of bottom (head), and supporting leg passes this through hole and is welded in the surface that bottom (head) exposes, and the aperture of through hole is bigger 8 millimeters than the external diameter of supporting leg, in order to guarantee that welding fully.
In one embodiment, the edge of through hole and the top of supporting leg have groove face, scolder forms leg again in the outside behind the slit of filling between bottom (head), backing plate and the supporting leg, thereby make the cross section of the weld seam between bottom (head), backing plate, the supporting leg be pentagon, increase weld strength in order to increase with the area of contact of scolder.
In one embodiment, backing plate is formed by connecting by four blocks of subpad plates.
In one embodiment, backing plate is the square that has rounded corner, and through hole is circular, and backing plate overlaps with the center of through hole, passes backing plate center and orthogonal two lines of cut backing plate is cut into the equal subpad plate of four areas.
In one embodiment, the side with backing plate is vertical respectively for two lines of cut, and every block of subpad plate comprises two right angle sides, a quadrant arc limit and two cutting edges between right angle side and circular arc limit that have rounded corner.In one embodiment, two lines of cut are respectively along the diagonal of backing plate, and every block of subpad plate comprises a straight flange, a quadrant arc limit and two cutting edges between straight flange and circular arc limit.Compare with monoblock backing plate of the prior art, backing plate of the present utility model is that the subpad plate by fritter is welded, be easier between itself and the end socket fit, avoid between backing plate and bottom (head) and supporting leg having bigger gap, thereby further improve the strength of connection, reduction bottom (head) of supporting leg and bottom (head) in the localized stress at support zone place.
In one embodiment, it is characterized in that, constitute backing plate by the cutting edge that welds four blocks of subpad plates, cutting surface is groove face, increases weld strength in order to the area of contact by increase and scolder.
In one embodiment, at least one air hole is set on the backing plate, the diameter of air hole is 8 millimeters, and supporting leg is the pipe perpendicular to ground, and its top has and the corresponding cambered surface of the arcuate surface of bottom (head).Air hole prevents backing plate deformation in order to discharge gas, and further improves the applying degree between bottom (head) and backing plate.
By the linkage structure that adopts the utility model to provide, at pressurized container in use, can reduce the wind load of substantially horizontal and the horizontal shear influence of earthquake loading, make the Security of container also obtain guarantee.

Embodiment
As shown in Figures 1 to 3, the utility model provides the linkage structure of a kind of pressurized container and supporting leg, it comprise pressurized container bottom (head) 10, be attached at bottom (head) 10 and middle backing plate 20 with a through hole 21, pass through hole 21 and be welded in the supporting leg of bottom (head) 10.
Bottom (head) 10 is the bottom (head) of fixing vertical pressurized container, and it has arcuate surface.
Supporting leg 30 passes through hole 21 and is welded in bottom (head) 10 and backing plate 20.The aperture of through hole 21 is bigger approximately 8 millimeters than the external diameter of supporting leg 30.In the present embodiment, supporting leg 30 is the pipe perpendicular to ground, and its top has and the corresponding cambered surface of the arcuate surface of bottom (head) 10.Between the top of supporting leg 30 and the bottom (head) 10, all leave suitable gap between the external diameter of through hole 21 and supporting leg 30, in order to welding between the edge of guaranteeing bottom (head) 10, through hole 21, the supporting leg 30 fully.As shown in Figure 3, preferably, the top of the edge of through hole 21 and supporting leg 30 has groove face, increases weld strength in order to the area of contact by increase and scolder.Scolder forms a leg again in the outside behind the slit of filling between bottom (head) 10, backing plate 20 and the supporting leg 30, in order to further to increase weld strength by the area of contact that increases scolder and supporting leg 30.Thus, the cross section of the weld seam 40 between bottom (head) 10, backing plate 20 and the supporting leg 30 is pentagon, in order to bottom (head) 10, backing plate 20 and supporting leg 30 threes are integrally welded securely.
In the linkage structure of pressurized container of the present utility model and supporting leg, because supporting leg directly is connected with bottom (head), join strength is between the two increased.Compare with monoblock backing plate of the prior art, backing plate of the present utility model is that the subpad plate by fritter is welded, be easier between itself and the end socket fit, avoid between backing plate and bottom (head) and supporting leg having bigger gap, thereby further improve the strength of connection, reduction bottom (head) of supporting leg and bottom (head) in the localized stress at support zone place.At pressurized container in use, this linkage structure can reduce the wind load of substantially horizontal and the horizontal shear influence of earthquake loading, makes the Security of container also obtain guarantee.
In sum; though the utility model discloses as above with preferred embodiment; so it is not in order to limit the utility model; those skilled in the art should recognize change and the retouching of doing under the situation that does not break away from the scope and spirit of the present utility model that the appended claim of the utility model discloses, all belong within the protection domain of claim of the present utility model.
