AI Technical Summary
Existing circumferential weld inspection brackets are prone to scratching the outer surface of pipe fittings when inspectors rotate them around the pipe fitting's axis.
A ring weld inspection bracket was designed, which uses a horizontally set base plate to install a set of support roller mechanisms. Each set of support roller mechanisms includes a pair of roller seats and support rollers. The rollers are in contact with the outer surface of the pipe to avoid sliding friction. The roller seats and rollers are made of hard metal to reduce friction.
It effectively avoids scratches on the outer surface of the pipe fittings, and has a simple structure and is easy to use.

Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of weld detection auxiliary device, concretely relates to a kind of annular weld detection support. BACKGROUND
[0002] Long-distance pipeline is formed by sequentially welding and connecting multiple pipe sections. In order to ensure welding safety and quality, it is necessary to detect annular welds (hereinafter referred to as welds). Weld detection mainly includes two parts of appearance detection and internal defect detection. Specifically, appearance detection is to detect the surface condition of the weld. First, check the size of the weld, including whether the excess height and width of the weld meet the design requirements; second, check whether the weld surface has surface defects such as cracks, pores, slag inclusion, undercut and incomplete fusion. Internal defect detection is mainly used to check the internal condition of the weld.
[0003] The existing annular weld detection support includes a bottom plate and a support plate. The support plate is vertically arranged on the bottom plate, and the support plate is provided with a groove with an upward opening. The support plate is provided with at least two support plates, and the at least two support plates are arranged at a distance from each other along the horizontal direction. The grooves on each support plate are coaxially arranged. The pipe connected by welding is placed in the groove, and the weld is located between the two adjacent support plates. The inspector rotates the pipe clockwise or counterclockwise around the axis of the pipe to detect the weld of the pipe. When the inspector rotates the pipe around its own axis, the inner surface of the groove and the outer surface of the pipe are in sliding friction, which is easy to scratch the outer surface of the pipe.

[0005] The utility model solves the technical problems by adopting the following technical scheme: an annular weld detection support includes a horizontally arranged bottom plate, and a support roller mechanism group is arranged above the bottom plate. With a plane rectangular coordinate system as a reference system, the support roller mechanism group is provided with at least two groups, and the at least two groups of support roller mechanism groups are arranged at a distance from each other along the x-axis direction. Each support roller mechanism group includes two support roller mechanisms arranged in pairs, and the two support roller mechanisms are arranged at a distance from each other along the y-axis direction. The support roller mechanism includes a roller seat and a support roller in rotation cooperation. The roller seat of each support roller mechanism is connected to the bottom plate, and the support roller of each support roller mechanism is arranged upward. The support rollers of each support roller mechanism group have a pipe placement distance.
[0006] Further, the roller seat and the support roller are connected by a rotating shaft. With a plane rectangular coordinate system as a reference system, the axis of the rotating shaft is parallel to the x-axis.
[0007] Further, the height of each of the support rollers is equal, and the diameter of each of the support rollers is equal.
[0008] The distance between the support rollers of the two support roller mechanisms of each of the support roller mechanism groups is equal.
[0009] Further, the roller seat, the support roller, and the bottom plate are all hard metal products.
[0010] Further, the roller seat and the upper surface of the bottom plate are welded together.
[0011] Compared with the prior art, the annular weld detection support provided by the utility model can avoid scratching the outer surface of the pipe when the inspector rotates the pipe along its own axis, and has the advantages of simple structure, convenient use, and the like.
