Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail bottom inspection technology, specifically to a rail bottom damage inspection device. Background Technology
[0002] Rails are the main load-bearing components of railway tracks. They are usually made of high-strength steel, are long and strip-shaped, and are laid on sleepers to guide and support the movement of train wheels, bear the train load and transfer it to the roadbed, and ensure the safe, smooth and efficient operation of trains.
[0003] Inspection of rail base damage is crucial because cracks in the rail base are hidden and easily expand, which may lead to breakage or track collapse, threatening traffic safety. Regular inspections can detect hidden dangers in time, prevent small damages from developing into big problems, and reduce maintenance costs, which is especially critical in harsh environments such as heavy loads and high-altitude cold.
[0004] Rail base damage inspection is mostly done visually, directly observing whether there are external damages such as missing pieces, scratches, and obvious cracks on the rail base surface. It is the "first line of defense" in flaw detection work. However, during the inspection, workers need to turn to the side or crawl to conduct the inspection, which is less efficient and requires a lot of labor intensity. Utility Model Content

[0011] As a preferred embodiment of the above technical solution, an internally threaded component is fixedly installed at the bottom of the circular box, and an externally threaded block is threadedly connected to the bottom of the internally threaded component.
[0012] As a preferred embodiment of the above technical solution, a bent rod is fixedly installed at the bottom of the external threaded block, and a roller is rotatably connected to the end of the bent rod away from the external threaded block.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] like Figures 1-5 As shown, this utility model provides a technical solution: a rail base damage inspection device, comprising: a handle 1; an auxiliary inspection mechanism 2, which is disposed at the end of the handle 1 and is used to display the captured image of the rail base; and a shooting inspection mechanism 3, which is disposed on the auxiliary inspection mechanism 2 and is used to capture the image of the rail base. The shooting inspection mechanism 3 includes a circular box 31, a camera 36 fixedly installed at the bottom of the inner wall of the circular box 31, a supplementary light 37 fixedly installed at the bottom of the inner wall of the circular box 31, a circular cover 34 movably inserted into the top of the circular box 31, a transparent plate 35 fixedly installed on the inner wall of the circular cover 34, a frame block 32 fixedly installed on the outer wall of the circular box 31, and an insertable... Block 33 is movably inserted into the inside of frame block 32. The user can hold this structure from the handle 1 and then manually adjust the position of the shooting inspection mechanism 3 so that it is located below the rail. At this time, the shooting end of the camera 36 faces upward. Control the camera 36 to work and shoot the image of the bottom of the rail through the transparent plate 35. Then transmit the image to the integrated display 25 for display, improving the convenience and efficiency of the bottom rail inspection. During the operation of the camera 36, control the working of the supplementary light 37 to provide supplementary light to the shooting end of the camera 36 and improve the shooting effect. There is a bolt on the frame block 32, which is movably abutted against the outer wall of the insert block 33. If the camera 36 needs to be maintained, loosen the bolt and then pull the circular cover 34 out from the top of the circular box 31, and then the maintenance work can be carried out.
[0027] As one implementation method in this embodiment, such as Figure 3 As shown, an internal threaded component 38 is fixedly installed at the bottom of the circular box 31. An external threaded block 381 is threadedly connected to the bottom of the internal threaded component 38. The external threaded block 381 is installed and removed from the bottom of the internal threaded component 38 by rotation. When the space at the bottom of the rail is small, the external threaded block 381 and other components can be removed.
[0028] As one implementation method in this embodiment, such as Figure 3 As shown, a bent rod 382 is fixedly installed at the bottom of the external threaded block 381. A roller 383 is rotatably connected to the end of the bent rod 382 away from the external threaded block 381. Through the design of the roller 383, the user can push the structure along the rail at the bottom, saving arm strength.
[0029] As one implementation method in this embodiment, such as Figure 5 As shown, the auxiliary inspection mechanism 2 includes a cylinder 21, which is fixedly installed at the end of the handle 1. An inner tube 211 is slidably connected in the inner cavity of the cylinder 21. A receiving block 212 is fixedly installed at the bottom of the inner tube 211. The distance between the handle 1 and the inspection mechanism 3 can be adjusted for users of different heights. The adjustment function is achieved by sliding the inner tube 211 inside the cylinder 21. A bolt is included on the outer wall of the cylinder 21 near the end. The bolt abuts against the outer wall of the inner tube 211. The bolt can be loosened before adjustment.
[0030] As one implementation method in this embodiment, such as Figure 5 As shown, a rotating arm 213 is rotatably connected to the inner wall of the receiving block 212. A circular box 31 is fixedly installed at the end of the rotating arm 213. A kit 214 is fixedly installed on both sides of the receiving block 212. A locking bolt 215 is threadedly connected to the outer wall of the kit 214. The threaded end of the locking bolt 215 movably abuts against the outer wall of the rotating arm 213. The user can rotate and adjust the angle of the imaging inspection mechanism 3 at the end of the inner tube 211 for easy use. When adjusting, the locking bolt 215 is loosened to release the state in which the rotating arm 213 is locked inside the receiving block 212 and the kit 214. Then the rotating arm 213 can be rotated to adjust the imaging inspection mechanism 3.
[0031] As one implementation method in this embodiment, such as Figure 4As shown, a sleeve 22 is fixedly installed on the outer wall of the cylinder 21, and a support block 23 is fixedly installed on the top of the sleeve 22. A damping shaft 24 is rotatably connected to the inner wall of the support block 23. An integrated display 25 is fixedly installed on the outer wall of the damping shaft 24, and a battery 26 is fixedly installed on the outer wall of the sleeve 22. The battery 26 controls the operation of the camera 36, which can capture images of the bottom of the track and then transmit them to the integrated display 25 for display. The battery 26 is used to power the electrical components. It is worth noting that the camera 36, the supplementary light 37, the integrated display 25, and the battery 26 in this solution are commercially available to those skilled in the art. The device in this paper has not undergone structural modifications. Therefore, those skilled in the art are familiar with its working principle based on their professional knowledge and can apply it proficiently. Thus, this paper will not elaborate on it further. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.
[0032] As one implementation method in this embodiment, such as Figure 4 As shown, the auxiliary inspection mechanism 2 also includes a mounting plate 27. A plastic bracket 28 is fixedly installed on the outer wall of the mounting plate 27. The cylinder 21 is movably inserted into the inner side of the plastic bracket 28. The mounting plate 27 can be installed on the wall of the control room. When the structure is not in use, the cylinder 21 can be inserted into the inside of the plastic bracket 28 and stored in the control room for easy organization.
[0033] Working principle: When in use, the user can hold the structure from the handle 1 and then manually adjust the position of the shooting inspection mechanism 3 so that it is located below the rail. At this time, the shooting end of the camera 36 is facing upward. Control the camera 36 to work and shoot the image at the bottom of the rail through the transparent plate 35. Then transmit the image to the integrated display 25 for display. Control the fill light 37 to work and provide fill light to the shooting end of the camera 36 to improve the shooting effect.
