Abstract
Description
Technical Field
[0001] This utility model relates to the field of radiographic testing technology, specifically to a field auxiliary tool for radiographic testing. Background Technology
[0002] A radiographic flaw detector is an instrument that uses the structural differences in local areas of an object as rays pass through it to change the attenuation of the rays, and then detects the intensity of the transmitted rays to determine the internal defects and material distribution of the object.
[0003] When installing or overhauling thermal power plants, for example, when inspecting the horizontal weld seams of heating surface tubes such as water-cooled walls (water-cooled screens) and wall-mounted superheaters (membrane structures), environmental factors make it inconvenient to set up an inspection platform for placing the radiographic flaw detector. The entire inspection process is time-consuming, labor-intensive, and inefficient.
[0004] Based on this, this utility model proposes an on-site auxiliary tool for radiographic testing. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary tool for on-site radiographic testing.
[0006] The technical solution adopted in this utility model is as follows:
[0007] A field auxiliary tool for radiographic testing includes: a support frame comprising a first section and a second section, wherein the included angle between the first section and the second section is 90°; a suspension section fixedly connected to the first section and suspended from fins on the pipe to be tested; an abutment rod fixedly connected to the first section and arranged vertically with the suspension section, the abutment rod abutting against the surface of the pipe to be tested, such that the first section is in a vertical state and the second section is in a horizontal state; and a springboard fixing section fixedly connected to the second section, forming a springboard connection port with the second section, the springboard passing through the springboard connection port, and the springboard being used to place the radiographic testing instrument.
[0008] The support frame has a right-angled triangular structure, with the first segment and the second segment being the two right-angled sides of the support frame.
[0009] Both the suspension part and the springboard fixing part have a U-shaped structure.
[0010] The suspension part and the abutment rod are fixedly connected to the first section through an adjustment assembly. The adjustment assembly includes: two first nuts, which are fixedly connected to the first section, and the abutment rod is fixedly connected to the first nuts; a screw, which is threadedly connected to the two first nuts; and a second nut, which is threadedly connected to the screw, and the second nut is smaller than the size of the first nuts.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] like Figure 1 and Figure 3 As shown in the figure, an auxiliary tool for on-site radiographic testing according to an embodiment of the present invention may include a support frame 1, a suspension part 2, a connecting rod 3, and a springboard fixing part 4. The support frame 1 includes a first section 11 and a second section 12, with an included angle of 90° between the first section 11 and the second section 12. The suspension part 2 is fixedly connected to the first section 11 and is suspended on the fins between the pipes to be tested. The connecting rod 3 is fixedly connected to the first section 11 and is arranged vertically with the suspension part 2. The connecting rod 3 abuts against the surface of the pipe to be tested, so that the first section 11 is in a vertical state and the second section 12 is in a horizontal state. The springboard fixing part 4 is fixedly connected to the second section 12 and forms a springboard connection port 41 with the second section 12. The springboard passes through the springboard connection port 41 and is used to place the radiographic testing instrument.
[0026] In this embodiment of the utility model, the support frame 1, the suspension part 2 and the plank fixing part 4 are all made of bent steel bars. The suspension part 2 is integrally set with the support frame 1, and the plank fixing part 4 is welded to the support frame 1.
[0027] In one embodiment of this utility model, the support frame 1 has a right-angled triangular structure, which has a certain stability to ensure the firmness and safety of its structure. The first segment 11 and the second segment 12 are the two right-angled sides of the support frame 1. The support frame 1 also includes an inclined segment, which is welded to the first segment 11 to form a triangular structure.
[0028] In one embodiment of this utility model, such as Figure 1 As shown, both the suspension part 2 and the springboard fixing part 4 have a U-shaped structure. The springboard fixing part 4 and the springboard connection port 41 formed at the second end are adapted to the size of the springboard, and the springboard is snapped into the springboard connection port 41.
[0029] Example 2
[0030] like Figure 2 and Figure 4As shown, unlike Embodiment 1, the suspension part 2 and the support frame 1 are not integrally formed. The bracket, suspension part 2, and springboard fixing part 4 are all made of bent steel pipes. The suspension part 2 and the abutment rod 3 are fixedly connected to the first section through the adjustment assembly 5. Specifically, the adjustment assembly 5 may include two first nuts 51, a screw 52, and a second nut 53. The first nuts 51 are fixedly connected to the first section 11, and the abutment rod 3 is fixedly connected to the first nuts 51. The screw 52 is threadedly connected to the two first nuts 51. The second nut 53 is threadedly connected to the screw 52. The second nut 53 is smaller than the size of the first nuts 51. The suspension part 2 is fixedly connected to the second nut 53. The vertical position of the suspension part 2 can be adjusted by rotating the screw 52.
[0031] In this utility model, when using the tool, two auxiliary tools are used in conjunction. The two auxiliary tools are respectively suspended and fixed at both ends below the weld seam of the heated surface of a row of pipes. It should be noted that the support frames 1 at both ends are at the same height. After the suspension part 2 is fixed on the pipe to be tested, the two ends of the scaffold are placed in the two scaffold connection ports 41. The scaffold is placed horizontally. After the scaffold is placed, the X-ray flaw detector can be placed on the scaffold and moved to perform the corresponding X-ray flaw detection operation.
[0032] According to the embodiment of this utility model, the on-site auxiliary tool for radiographic testing is suspended on the fins between the pipes to be tested by the suspension part 2 and the abutment rod 3. The first section 11 of the support frame 1 is vertical, and the scaffold is inserted and installed at the scaffold fixing part 4. The overall structure is simple, and the inspection workers can quickly set up the inspection platform. The radiographic testing instrument is placed on the scaffold and moved left and right to achieve rapid weld quality inspection. The entire installation operation is not limited by the inspection environment. In addition, the suspension part 2 and the abutment rod 3 are connected to the support frame 1 through the adjustment component 5, which facilitates the adjustment of the inspection position.
