Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing technology, and in particular to a non-destructive testing device for high-temperature pipelines. Background Technology

[0002] In high-temperature industrial environments, pipelines, as crucial components for transporting various high-temperature media, directly impact the stable operation of the entire production system through their structural integrity and safety. However, prolonged operation under high temperature and pressure can lead to various defects within pipelines, such as cracks, corrosion, and wear. If these defects are not detected and addressed promptly, they can cause serious safety accidents.

[0003] Currently, when conducting flaw detection on pipelines, due to the varying sizes and shapes of pipelines, traditional testing equipment often needs to be customized according to specific pipeline specifications. This not only increases equipment costs but also limits the versatility and flexibility of the testing equipment. Utility Model Content

A knob is fixedly installed at the outer end of the threaded rod outside the cylinder, and a mounting plate is rotatably connected to the inner end of the threaded rod inside the cylinder. A round rod is fixedly installed on the side wall of the mounting plate near the hollow shaft. A displacement groove is formed on the outer wall of the round rod, and a displacement block is fixedly installed on the inner wall of the hollow shaft.

[0008] Preferably, the adapter mechanism includes a circular plate fixedly mounted on a hollow shaft. The circular plate has multiple sliding grooves, and a sliding rod is slidably connected to each of the multiple sliding grooves. Connecting blocks are fixedly mounted at both ends of the multiple sliding rods. Two connecting blocks located on the same sliding rod penetrate the inner wall of the cylinder and are slidably connected to it. The two connecting blocks located on the same sliding rod are fixedly mounted with the same mounting block located outside the cylinder. Each of the multiple mounting blocks is provided with a movable wheel.

[0009] Preferably, the displacement groove is spiral-shaped, and the displacement block is located inside the displacement groove and is slidably connected to the inner wall of the displacement groove.

[0010] Preferably, two guide rods are fixedly installed on the inner wall of the cylinder near the knob. Both guide rods pass through the mounting plate and are slidably connected to it. A fixing block is fixedly installed on the end of the two guide rods away from the knob.

[0011] Preferably, all of the grooves are arc-shaped.

[0012] The beneficial effects of this utility model are:

[0013] By setting up an operating mechanism and an adapter mechanism, the four moving wheels can be moved away from or closer to each other by turning the knob, thus flexibly adapting to pipes of different sizes, greatly enhancing the versatility and practicality of the equipment, and reducing the need to replace equipment of different specifications.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4A high-temperature pipeline non-destructive testing device includes a cylinder 1. A flaw detection head 2 is installed at one end of the cylinder 1. A hollow shaft 16 is rotatably connected to the inner wall of one end of the cylinder 1. An operating mechanism connected to the hollow shaft 16 is installed on the cylinder 1. The operating mechanism includes a threaded rod 5 that passes through and is threadedly connected to the outer wall of the other end of the cylinder 1. A knob 6 is fixedly installed at the end of the threaded rod 5 outside the cylinder 1. A mounting plate 8 is rotatably connected to the end of the threaded rod 5 inside the cylinder 1. A round rod 10 is fixedly installed on the side wall of the mounting plate 8 near the hollow shaft 16. A displacement groove 1 is formed on the outer wall of the round rod 10. 1. A displacement block 12 is fixedly installed on the inner wall of the hollow shaft 16. The displacement groove 11 is spiral. The displacement block 12 is located in the displacement groove 11 and is slidably connected to the inner wall of the displacement groove 11. The spiral design of the displacement groove 11 enables the displacement block 12 to drive the hollow shaft 16 to rotate during the sliding process. Two guide rods 7 are fixedly installed on the inner wall of the cylinder 1 near the knob 6. Both guide rods 7 pass through the mounting plate 8 and are slidably connected to it. The guide rods 7 are used to limit the movement trajectory of the mounting plate 8 and ensure its stability during the rotation process. A fixing block 9 is fixedly installed on the end of the two guide rods 7 away from the knob 6.

[0021] Two symmetrically arranged adapter mechanisms are provided on the hollow shaft 16. The adapter mechanism includes a circular plate 14 fixedly installed on the hollow shaft 16. The circular plate 14 has multiple sliding grooves 15. Each sliding groove 15 has a sliding rod 17 that is slidably connected to it. Each end of the sliding rod 17 is fixedly installed with a connecting block 13. The two connecting blocks 13 located on the same sliding rod 17 penetrate the inner wall of the cylinder 1 and are slidably connected to it. The two connecting blocks 13 located on the same sliding rod 17 are fixedly installed with the same mounting block 4 located outside the cylinder 1. Each mounting block 4 is provided with a moving wheel 3. The mounting block 4 serves as the support point for the moving wheel 3. Its structure is sturdy and can withstand a large load. The moving wheel 3 is made of high temperature resistant and wear resistant material and can operate stably for a long time in a high temperature environment. The multiple sliding grooves 15 are all arc-shaped. The arc design of the sliding grooves 15 allows the sliding rod 17 to drive the connecting block 13 and the mounting block 4 to move radially during the sliding process.

[0022] In use, the device is placed inside the pipe, and then the threaded rod 5 is rotated by manually turning the knob 6. The threaded rod 5 is rotatably connected to the mounting plate 8 and guided by two guide rods 7, so that the mounting plate 8 can move towards the hollow shaft 16. The mounting plate 8 drives the round rod 10 to move, so that the displacement block 12 on the hollow shaft 16 slides in the spiral displacement groove 11, thereby rotating the hollow shaft 16. The rotation of the hollow shaft 16 drives the round plate 14 to rotate, thereby causing the slide rod 17 to slide in the arc-shaped slide groove 15. By setting the connecting block 13, the four moving wheels 3 can be moved away from or close to each other, so that the device can be adapted to pipes of different sizes and is simple and convenient to operate.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
