Abstract
The utility model relates to a curved pipe section connector welding structure. A curved pipe section comprises the pipe section bell of a first pipe section and the pipe section spigot of a second pipe section. The pipe section bell is provided with first outer diameter being smaller than the outer diameter of the pipe body of the first pipe section. The pipe section spigot is provided with first inner diameter being larger than the inner diameter of the pipe body of the second pipe section. A sealing assembly is arranged between the outer wall of the pipe section bell and the inner wall of the pipe section spigot. The curved pipe section connector welding structure is characterized in that a web extends towards the external end surface of the pipe section bell in the axial direction of the inner wall of the second pipe section, the web extends to the external end surface of the pipe section bell, the web is welded with the external end surface of the pipe section bell, the web is also welded with the inner wall of the second pipe section and therefore the first pipe section and the second pipe section are connected together.
Description
Technical field
The utility model relates to the welded structure of steel pipe joint interface, relates in particular to the curve tube coupling joint weld structure after large-diameter steel pipe curve jacking construction is finished
Background technique
In the large-diameter steel pipe jack-in process, the steel pipe interface adopts articulated manner to connect, and characteristics such as higher working pressure are arranged because of conduit pipe, adopts which kind of welding manner, is a great problem of large-diameter steel pipe curve jacking.If adopt conventional " V " type groove, can't guarantee the fusion penetration of weld seam, do not reach desired strength.
The model utility content
The purpose of this utility model is to provide a kind of curve tube coupling joint weld structure, so that the weld strength of the tube coupling interface that articulated manner connects meets the requirements.
For realizing the curve tube coupling joint weld structure of described purpose, this curve tube coupling comprises the tube coupling bellmouth of first tube coupling and the tube coupling socket of second tube coupling, the tube coupling bellmouth has first external diameter less than the body external diameter of first tube coupling, the tube coupling socket has first internal diameter greater than the internal diameter of tube body of second tube coupling, be provided with black box between the inwall of the outer wall of tube coupling bellmouth and tube coupling socket, be characterized in, inwall at second tube coupling axially extends the exterior edge face that web and web extend to the tube coupling bellmouth towards the exterior edge face of tube coupling bellmouth, the exterior edge face welding of this web and tube coupling bellmouth, this web also with the welding of the inwall of second tube coupling, thereby first tube coupling and second tube coupling are linked together.
Inwall at second tube coupling axially extends the exterior edge face that web and web extend to the tube coupling bellmouth towards the exterior edge face of tube coupling bellmouth, the exterior edge face welding of this web and tube coupling bellmouth, this web also with the welding of the inwall of second tube coupling, thereby first tube coupling and second tube coupling are linked together, rather than be chosen on the original architecture basics of tube coupling bellmouth and tube coupling socket and directly weld, thereby guaranteed between the web and the second tube coupling inwall, between web and the tube coupling bellmouth end face enough fusion penetrations are arranged, and then guaranteed that the weld strength of the tube coupling interface that the mode that connects connects meets the requirements.
Description of drawings
Fig. 1 is the curve tube coupling interface structure before the welding.
Fig. 2 is the curve tube coupling interface structure after the welding.
Embodiment
As shown in Figure 1, curve tube coupling interface comprises the tube coupling bellmouth 11 of first tube coupling 1 and the tube coupling socket 21 of second tube coupling 2, tube coupling bellmouth 11 has first external diameter less than the body external diameter of first tube coupling 1, tube coupling socket 21 has first internal diameter greater than the internal diameter of tube body of second tube coupling 2, is provided with black box 30 between the inwall of the outer wall of tube coupling bellmouth 11 and tube coupling socket 21.Tube coupling 1 and tube coupling 2 are hinged, promptly the flange 22 of the flange 12 of tube coupling bellmouth 11 and tube coupling socket 22 connect by bolt and between wooden dunnage 3 is arranged, bolt does not connect dead, has certain activity.In the curve tube coupling head part work progress because as shown in Figure 1 bell and spigot frame thereby have can movable relatively relation, thereby can realize the curve jacking construction of bigbore steel pipe joint.
After construction finishes, need be with tube coupling 1,2 welding, if directly on the basis of as shown in Figure 1 structure, weld, then there is the not enough problem of fusion penetration.As shown in Figure 2, cut off the wooden dunnage 3 between flange 12, flange 22 and flange 12 and the flange 22, inwall at second tube coupling 2 axially extends the exterior edge face that web 4 and web 4 extend to tube coupling bellmouth 22 towards the exterior edge face of tube coupling bellmouth 22, the exterior edge face welding of this web 4 and tube coupling bellmouth 22, this web 4 also with the welding of the inwall of second tube coupling 2, thereby first tube coupling 1 and second tube coupling 2 are linked together.
