Detailed Description

The following detailed description is to be read in connection with the drawings and the preferred embodiments.

A pipeline elbow support is shown in figures 2 to 3 and comprises a reinforcing plate 1, a bottom plate 2, an axial rib plate 3 and a radial rib plate 4, wherein the bottom plate 2 is used for being connected with a field support top plate 51 at the top end of a steel pipe 5 for a field support, in the embodiment, a plurality of fixing holes 21 are formed in the bottom plate 2, bolts 6 penetrate through the fixing holes 21 and corresponding holes in the field support top plate and then are in locking fit with nuts, connection between the bottom plate and the field support top plate is achieved, and a field support bottom plate 52 at the bottom end of the steel pipe for the field support is used for being fixed on a corresponding installation carrier.

The axial rib plates 3 comprise first axial rib plates 31 and second axial rib plates 32, the bottom ends of the two axial rib plates are welded on the upper end face of the bottom plate 2, the top ends of the two axial rib plates are welded on the lower end face of the reinforcing plate 1, and the two axial rib plates are vertically arranged; the first axial rib plates and the second axial rib plates are distributed oppositely, and the extension directions of the plate surfaces of the first axial rib plates 3 and the second axial rib plates 4 are on the axis of the elbow 7 in the top view shown in fig. 3, so that the first axial rib plates and the second axial rib plates can axially support the elbow 7 and pipelines 8 at two ends of the elbow.

The two radial rib plates 4 are symmetrically arranged on two sides of the axial rib plate 3, the bottom ends of the two radial rib plates are welded with the upper end face of the bottom plate 2, the top ends of the two radial rib plates are welded with the lower end face of the reinforcing plate 1, and the radial rib plates are perpendicular to the axial rib plates. As seen from the top view shown in fig. 3, the plate surface extending direction of the radial rib plate is in the radial direction of the elbow, so that the elbow can be radially supported; the supporting force of the axial rib plate and the radial rib plate to the elbow and the pipeline is transmitted through the reinforcing plate. Preferably, the radial rib plates incline towards the direction of the circle center corresponding to the elbow and are still perpendicular to the axial rib plates, so that the radial rib plates have a better supporting effect on the elbow.

The stiffening plate 1 is the arc plate shape of laminating with the lower extreme cambered surface looks adaptation of elbow to carry out the parcel formula to the lower extreme of elbow and support, increased with the area of contact of elbow lower surface, make support stability better. The stiffening plate 1 is connected for the full weld with elbow 7, promptly the contact surface outside of stiffening plate and elbow should be full weld all around, guarantees joint strength to stiffening plate and elbow should keep same material. Because the reinforcing plate 1 is of an arc-shaped plate structure, the height of the first axial rib plate is smaller than that of the second axial rib plate, the two radial rib plates have the same structure, and the welded ends of all the axial/radial rib plates and the reinforcing plate are in corresponding arcs, so that the lower end face of the reinforcing plate, which is in an arc shape, can be attached conveniently and welded conveniently. Preferably, the axial rib plates, the radial rib plates and the bottom plate can be made of carbon steel materials with corresponding strength according to the size of the pipeline load.

In this embodiment, stiffening plate 1, bottom plate 2, axial gusset 3 and radial gusset 4 all weld or assemble before the elbow leaves the factory, during the field installation, only need to be connected bottom plate 2 and field support roof 51 with the fastener or directly to the right place can to effectively avoid welding in elbow department during field construction, especially the elbow department of small-bore pipeline, if the direct welding, will certainly lead to the fact destruction to the intensity of elbow, influence the elbow and use the atress, cause here to leak even when serious. In addition, if the elbow on this pipeline is stainless steel or alloy steel material, adopts the utility model discloses the welded condition of xenogenesis steel not only can effectively be avoided appearing at the scene to the elbow support, has still avoided the support can't carry out the condition of thermal treatment with the elbow piece.

The above description is only a preferred embodiment of the present invention, and any person skilled in the art can easily modify, change or modify the above embodiments according to the technical spirit of the present invention without departing from the scope of the present invention.
