Description

Technical Field

[0001] This utility model relates to the field of stainless steel technology, and in particular to a three-dimensional inspection device for high-temperature gas-cooled reactor nuclear-grade stainless steel pipe fittings. Background Technology

[0002] Nuclear power is one of the most important clean energy sources today and a crucial means to achieve the "dual carbon" goals of carbon peaking and carbon neutrality. It has been widely used in countries around the world. Nuclear-grade stainless steel is a type of stainless steel material with high structural stability, a small neutron absorption cross-section, and low induced radioactivity. Nuclear-grade stainless steel is used in the manufacture of corrosion-resistant equipment or components in the primary loop of the nuclear island of nuclear power plants that come into contact with high-level radioactive coolants. Based on the safety level of nuclear equipment, it is classified into Nuclear Class 1, 2, and 3, with Nuclear Class 1 materials having the highest technical and quality assurance requirements. Due to its superior composition and performance, nuclear-grade stainless steel can meet the manufacturing requirements of equipment in major scientific research fields such as neutrino detection, dark matter detection, and hard X-ray sources, thus expanding its application areas.

[0003] Most existing stainless steel pipes are around three meters long, but different lengths may be available depending on site conditions. To ensure the stability of nuclear-grade stainless steel pipes during use, their length needs to be measured and tested before use. During the testing process, the following problems were found in the existing technology, which have not been adequately resolved:

[0004] Because nuclear-grade stainless steel tubes are mostly large in size, it is extremely difficult to place them on top of or remove them from the testing device, which affects the testing efficiency and makes the testing process slower. Utility Model Content

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0022] By setting up a support block and a discharge plate that are level with the extension block, the discharge plate and the second push rod use a mechanical structure to quickly push the stainless steel pipe above the support block, and then into the extension block for inspection. This facilitates the rapid movement of the stainless steel pipe storage and retrieval equipment, avoiding difficulties in storage and retrieval due to its large size, which would affect the inspection efficiency.

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1-4This utility model provides an embodiment of a three-dimensional inspection device for stainless steel pipe fittings of high-temperature gas-cooled reactors, comprising a device body 1, a drive screw 4 inside the device body 1, threaded blocks 3 connected to both sides of the drive screw 4, the threaded blocks 3 drive the clamping block 2 to move, and perform automatic measurement. The clamping block 2 is connected above the threaded blocks 3. A base plate 5 is also connected above the device body 1, and an extension block 7 is connected above the base plate 5. The extension block 7 cooperates with the movable block 9 to make the auxiliary block 8 movable, ensuring its fixed operation. The movable blocks 9 are connected to both sides of the extension block 7, and the auxiliary block 8 is connected to the outside of the movable block 9. A first push rod 6 is connected below the auxiliary block 8, and the first push rod 6 drives the auxiliary block 8 to automatically rise and fall, thereby realizing automatic clamping.

[0030] A support block 10 is connected to the top of the main body 1 of the device. A sliding block 11 is connected to the other side of the support block 10. A discharge plate 12 is connected to the other side of the sliding block 11. The discharge plate 12 and the sliding block 11 cooperate to ensure that the discharge plate 12 can be raised and lowered stably. An anti-detachment block 13 is connected to the outside of the discharge plate 12. A second push rod 14 is connected to the bottom of the discharge plate 12. The second push rod 14 is used to drive the discharge plate 12 to rise and fall automatically, so as to realize the disassembly of the stainless steel pipe.

[0031] Working principle: When in use, first, place the stainless steel tube to be tested above the unloading plate 12, then turn on the switch of the second push rod 14, so that it drives the unloading plate 12 to rise until the top of the unloading plate 12 is on the same horizontal line as the top of the support block 10. Then rotate the stainless steel tube until it rotates above the extension block 7 and stops moving.

[0032] As described above, the switch of the first push rod 6 is then turned on, causing the auxiliary block 8 to rise. When the auxiliary block 8 rises, the movable block 9 and the extension block 7 rotate, forming a V-shaped groove that clamps the stainless steel tube in the central area. Then, the drive motor on one side of the drive screw 4 starts to work, causing the drive screw 4 and the threaded block 3 to move in a threaded motion. Then, the clamping block 2 moves towards the center and fits against both sides of the stainless steel tube. The length of the stainless steel tube can be checked according to the number of rotations of the drive screw 4 or by directly using a scale on the top of the main body 1 of the device, thus completing the inspection work.

[0033] It should be further explained that the clamping block 2 forms a threaded motion with the drive screw 4 through the threaded block 3. The threads on both sides of the drive screw 4 are in opposite directions. The clamping block 2 is connected to the main body 1 of the device by a sliding connection. Through the cooperation of the clamping block 2 and the threaded block 3, the drive screw 4 can drive the clamping block 2 to move in opposite directions, which facilitates the rapid measurement work.

[0034] It should be noted that the base plate 5 is installed as an integral part of the main body 1 of the device. The first push rods 6 are symmetrically distributed on both sides of the base plate 5. The first push rods 6 are installed as an integral part of the auxiliary block 8. Through the cooperation of the base plate 5 and the first push rods 6, the auxiliary block 8 is driven to move up and down quickly, which facilitates the limiting and fixing of the stainless steel pipe.

[0035] It should be noted that the extension block 7 is connected to the base plate 5 by heat fusion, and the extension block 7 is connected to the movable block 9 by rotation. The movable block 9 and the auxiliary block 8 are installed as a whole. The extension block 7 and the base plate 5 cooperate to quickly limit and fix the movable block 9, which facilitates the movement of the auxiliary block 8.

[0036] It should be noted that the support block 10 is connected to the main body 1 of the device by heat fusion, and the support block 10 is connected to the sliding block 11 by sliding connection. The top of the support block 10 and the top of the extension block 7 are on the same horizontal line. The cooperation between the support block 10 and the sliding block 11 facilitates the rapid lifting and lowering of the stainless steel pipe, thereby improving the detection efficiency.

[0037] It should be noted that the unloading plate 12 is symmetrically distributed with second push rods 14 below it. The connection between the unloading plate 12 and the sliding block 11 is a heat fusion connection. The unloading plate 12 and the anti-detachment block 13 are installed as an integral unit. Through the cooperation of the unloading plate 12 and the anti-detachment block 13, the unloading plate 12 can quickly drive the stainless steel pipe up and down, which can improve work efficiency.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
