Disclosure of Invention

An object of the utility model is to provide a flange is support for pipeline welding can stabilize the mounting flange pipeline, satisfies flange pipeline welded requirement.

The utility model adopts the technical proposal that: the utility model provides a flange is support for pipeline welding, includes the frame plate, the upper surface center recessed V type groove that is formed with of frame plate, V type groove for joint mounting flange pipeline, a plurality of blind holes have evenly been seted up in V type groove both sides to the upper surface of frame plate, all the cooperation is connected with the bolt in every blind hole, the bolt is used for connecting the mounting flange pipeline, the frame plate both ends have linked firmly many spinal branchs vaulting pole respectively, joint mounting flange pipeline between many spinal branchs vaulting pole.

The utility model is also characterized in that,

the center line of the V-shaped groove is vertical to the center line of the frame plate along the length direction of the frame.

The bottom of the V-shaped groove is a horizontal tool withdrawal groove.

The support rods positioned at the same end of the frame plate are parallel to each other, one end of each support rod is fixedly connected with the end part of the frame plate, and the other end of each support rod is a free end.

The bolt is in clearance fit with the blind hole.

The utility model has the advantages that: the utility model discloses a flange is support for pipeline welding, can be according to the various different shapes of flange pipeline, select different modes to support fixedly to the flange pipeline, pipe shaft through V type groove joint flange pipeline, flange joint flange pipeline on with the flange pipeline through the bolt, joint flange pipeline comes through the bracing piece, solved because the flange pipeline is not good when the welding owing to put the angle, the difficult fixed execution of welding that causes is difficult for, the welding seam quality is poor, the pipeline is put insecure and welding seam surface cleaning efficiency is low, the potential safety hazard scheduling problem that welding and whetting appear, the quality of flange pipeline welding seam can obviously obtain improving after using this frock, production efficiency improves greatly, manufacturing cost has been reduceed effectively, this frock simple structure simultaneously, the commonality is strong.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model relates to a flange is supporting structure for pipeline welding as shown in figure 1, figure 2 is shown, including frame plate 1, the upper surface center of frame plate 1 is recessed to be formed with V type groove 11, V type groove 11 central line is perpendicular with the central line of frame plate 1 along the frame length direction, 11 tank bottoms in V type groove are the horizontally tool escape 13, V type groove 11 is used for the joint mounting flange pipeline, a plurality of blind holes 12 have evenly been seted up at V type groove 11 both sides to the upper surface of frame plate 1, all the cooperation is connected with bolt 2 in every blind hole 12, bolt 2 is used for connecting the mounting flange pipeline, many spinal branchs vaulting pole 3 have been linked firmly respectively at frame plate 1 both ends, joint mounting flange pipeline between many spinal bra.

A plurality of support rods 3 which are positioned at the same end of the frame plate 1 are parallel to each other, one end of each support rod is fixedly connected with the end part of the frame plate 1, and the other end of each support rod is a free end.

The bolt 2 is in clearance fit with the blind hole 12.

The utility model relates to a flange pipeline welding explains with support principle: the utility model relates to a flange is support for pipeline welding, according to the various different shapes of flange pipeline, the concrete shape of flange pipeline is shown as figure 3, 4, has flange pipeline that both ends have the flange or one end have the flange, utilizes the different positions of support to support or fix the pipeline to realize the high-efficient welding and the welding seam surface cleaning of flange pipeline. For a longer pipeline, a plurality of supports arranged in a line are used for supporting the flange pipeline, as shown in fig. 3 and 4, a pipe body of the flange pipeline is clamped in a V-shaped groove 11, and it should be noted that when the pipe body diameter of the flange pipeline is larger, the flange pipeline is clamped in the V-shaped groove 11 for fixation, and when the pipe body diameter of the flange pipeline is smaller, the flange pipeline is clamped in a tool withdrawal groove 13 at the bottom of the V-shaped groove 11 for fixation; for a shorter pipeline, the pipeline can be supported by the support rods 3 on the bracket, as shown in fig. 5, the pipe body of the flange pipeline is positioned among the support rods 3, and the support rods 3 bear the flange at the same time, so that the welding of the flange line welding seam is realized by fixing; for the rest flange pipelines, overturn easily when placed freely, the flange pipelines can be fixed on the frame body 1 through the bolts 2, as shown in fig. 6, the surface of the flange is attached to the upper surface of the frame body 1, the bolts 2 penetrate through the flange to fix the flange pipelines by connecting the flange and the frame body 1, and then the circumferential weld joints of the flange pipelines are welded.
