Problems solved by technology

[0005] However, although the above scheme can detect welded straight pipes, it cannot detect welded bent pipes; the actual flaw detection process not only needs to detect uninstalled pipes, but sometimes also needs to inspect installed pipes. inspection; and not only flaw detection of the weld seam is required, but also the formed pipe itself
If the ray flaw detector in the prior art wants to adapt to various operating environments, it needs to adopt manual means, but manual work cannot be used continuously for a long time, especially for manifold systems with long pipelines and many bends; and manual The detection error is large, and the operator also has the risk of being irradiated

Embodiment 1

[0037] Such as figure 1 The auxiliary device for flaw detection of a radiation-proof curved pipe shown in -14 includes a detection ring 1, a power assembly 2 is provided on the left and right sides of the detection ring 1, and a connecting piece 3 is provided between the power assembly 2 and the detection ring 1 .

[0038] In this embodiment, the detection ring 1 includes a first detection half-ring 101, a second detection half-ring 102, a sliding motor base 105, a radiation-proof casing 106, and a rotation connection in the middle of the detection ring 1 and consists of two half-rings A rotating ring 111, one end of the first detection half ring 101 and the second detection half ring 102 is provided with a hinge seat 120, the other end of the first detection half ring 101 and the second detection half ring 102 Hasps 121 are provided, inner and outer T-shaped slots 109 and outer T-shaped slots 110 are respectively arranged on the inner and outer sides of the first detection h...

Embodiment 2

[0046] In this embodiment, other settings are the same as the embodiment, the only difference is that: the linear drive device 107 is an electromagnetic push rod, and the electromagnetic push rod is a kind of linear reciprocating motion of the push rod by using the working characteristics of the electromagnet. Action actuator.

Embodiment 3

[0048] In this embodiment, other settings are the same as those in the embodiment, the only difference is that anti-radiation pads 117 are arranged on both sides of the first detection half-ring 101 and the second detection half-ring 102, and the anti-radiation The pad 117 is in the shape of a fan ring, and the inner edge of the anti-radiation pad 117 is provided with several evenly distributed fringe strips 118. On the ring 102, the radiation protection effect is better.

[0049] How to use: The invention provides an auxiliary device for detection of radiation-proof curved pipes. Before use, the motor is positioned in the center of the first detection half-ring 101, so that the two half-rings that make up the rotating ring 111 are just located in the first detection half-ring 101. and the second detection half-ring 102, and open the buckle 121, and at the same time unscrew the lowermost thread limiter 208 on the secondary shaft 207, so that the lowermost rubber wheel 209 is p...

Abstract

The invention relates to the field of steel pipe welding seam flaw detection equipment, in particular to an anti-radiation bent pipe flaw detection auxiliary device. The device comprises a detection ring, power assemblies are arranged on the left side and right side of the detection ring, and connecting pieces are arranged between the power assemblies and the detection ring. The operation is simple and the design is reasonable; the device not only can detect a welded straight pipe, also can detect a welded bent pipe, not only can detect an uninstalled pipeline, but also can detect an installedpipeline, not only can perform flaw detection on a weld seam, but also can detect a formed pipeline itself, can adapt to various different operation environments, realize long-time continuous operation, and is particularly suitable for manifold systems with long pipelines and many bends, the detection error is small, and the risk that an operator is radiated is avoided.

Description

technical field [0001] The invention relates to the field of flaw detection equipment for welded seams of steel pipes, in particular to an auxiliary device for flaw detection of radiation-proof bent pipes. Background technique [0002] Non-destructive testing is a technology to detect defects, chemical and physical parameters of materials, parts and equipment by using sound, light, electromagnetic and other principles and technologies of objects without damaging or affecting the performance of the tested object; non-destructive testing is an industrial The development of essential and effective tools reflects the industrial development level of a country to a certain extent. The importance of non-destructive testing has been recognized. There are four main types: radiographic testing, ultrasonic testing, magnetic particle testing and liquid penetrant testing. [0003] In the field of steel pipe production, after the steel pipe is welded, the flaw detection method of the weld...
