Description

Technical Field

[0001] This application relates to the field of track inspection vehicle technology, specifically a track surface inspection device. Background Technology

[0002] Track inspection vehicles are key equipment that have emerged alongside the development of railways. In the early stages, manual inspection was inefficient and inaccurate. Later, through the mechanical and electrical track inspection vehicle stages, dynamic inspection was gradually realized. After the 1970s, with the advancement of electronic and computer technology, high-speed electronic track inspection vehicles became the mainstream. They can detect track conditions with multiple parameters, high precision, and real-time monitoring, supporting scenarios such as daily railway maintenance, high-speed joint commissioning and testing, and emergency response. In the future, they are continuing to evolve towards intelligence, integration, and unmanned operation.

[0003] For example, patent CN213768567U discloses a scraper for an intelligent track inspection trolley. By mounting a scraper on the outward side of the support arm of the intelligent track inspection trolley, it can clean up track obstacles, improve inspection efficiency and accuracy. The scrapers on both sides can increase its practicality and adapt to different environments. The inclined mounting makes it easy for the scraper to discharge obstacles to the outside of the track when cleaning obstacles, which improves cleaning efficiency and practicality.

[0004] In the aforementioned patent, the track inspection trolley uses scrapers to clean debris from the track while it is in motion. However, since the trolley only uses two sets of scrapers to remove debris, and the track surface is not completely smooth, there may be various irregular protrusions, depressions, or localized debris accumulation. It is difficult to fully cover all corners of the track using only scrapers. This results in some hidden areas or special terrain features of the track where debris cannot be effectively cleaned and will remain on the track, potentially interfering with subsequent inspection work. Therefore, it is necessary to provide an inspection device that can comprehensively clean dirt from the track surface to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a track surface detection device that can quickly clean up debris on the track surface.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] like Figures 1-2 As shown, this application provides a track surface inspection device, including an inspection vehicle 1, which is installed on a railway track for inspecting and cleaning the track;

[0024] The inspection vehicle 1 includes a body 11, and an inspection camera 12 is installed on the front side of the body 11. The camera 12 is used to detect whether there are debris on the track. At the same time, multiple sets of track wheels 13 are installed at the bottom of the body 11 to ensure that the inspection vehicle 1 can move smoothly and quickly on the track, thus providing a guarantee for efficient inspection and cleaning operations.

[0025] Meanwhile, a cleaning mechanism 2 is also installed on the inspection vehicle 1. The cleaning mechanism 2 includes two sets of first motors (not shown in the figure) installed inside the vehicle body 11. The output end of the first motor passes through the vehicle body 11 and is fixedly installed with a connecting column 21. A support arm 22 is rotatably installed on the connecting column 21. The support arm 22 is inclined, which not only ensures the cleaning effect but also avoids direct collision with the track. A scraper 23 is fixedly installed on the side of the support arm 22 away from the vehicle body 11. The scraper 23 is made of high-strength plastic and is installed at an angle. Its bottom is in contact with the track surface, which initially and effectively scrapes away the stubborn debris on the top of the track, laying a solid foundation for subsequent cleaning work.

[0026] Meanwhile, a support rod 3 is also provided at the bottom of the vehicle body 11. A tray 31 is fixedly installed on one side of the support rod 3, and a second motor 32 is fixedly installed on the top of the tray 31. The output end of the second motor 32 passes through the tray 31 and is fixedly installed with a brush 33. The brush 33 is suitable for contacting the track. Driven by the second motor 32, the brush 33 rotates at high speed, which can quickly and thoroughly clean the dust and residual debris on the track surface, ensuring that the cleanliness of the track surface reaches the best state.

[0027] like Figures 3-4 As shown, a spraying assembly is provided at the rear of the vehicle body 11. The spraying assembly includes a connecting rod 4 fixedly installed at the bottom rear of the vehicle body 11. An installation plate 41 is fixedly installed at the end of the connecting rod 4 away from the vehicle body 11, and a liquid storage tank 42 is provided on the top of the installation plate 41. The liquid storage tank 42 stores a protective liquid containing various components such as corrosion inhibitors, rust inhibitors, and lubricants. It can quickly form a uniform and dense protective film on the track surface, thereby effectively extending the service life of the track. At the same time, a connecting pipe 43 is fixedly installed at the bottom of the installation plate 41. The connecting pipe 43 is connected to the liquid storage tank 42, and an electric control switch (not shown in the figure) is provided inside the installation plate 41. Through intelligent control, the flow of the protective liquid in the liquid storage tank 42 into the connecting pipe 43 can be precisely controlled to achieve on-demand spraying.

[0028] Meanwhile, multiple sets of nozzles 5 are provided at the bottom of the connecting pipe 43. These nozzles 5 are used to spray the protective liquid evenly, so that the protective liquid forms a protective film on the track surface, providing continuous protection for the track.

[0029] When the track inspection area needs to be cleaned, the operator must first place the inspection vehicle 1 in a suitable position on top of the track, ensuring that the inspection vehicle 1 is firmly attached to the track. Then, driven by the power system, the inspection vehicle 1 moves forward at a constant speed along the track. When the camera 12 detects debris on the top of the track, the first motor drives the scraper 23 to contact the track and initially scrape away the dirt on the track, peeling off larger particles of debris from the track surface to prepare for subsequent deep cleaning. Then, the second motor 32 drives the brush 33 to rotate, thoroughly cleaning away the dust, small residues, and some difficult-to-clean contaminants that remain after the initial scraping. Then, the inspection vehicle 1 continues to move forward along the track. When the vehicle body 11 moves a certain distance behind the cleaned position, the nozzle 5 will start spraying protective liquid onto the track to extend the service life of the track.

[0030] In summary, this device, through the orderly cleaning process of the cleaning mechanism 2, achieves efficient and comprehensive removal of various debris from the track surface, protects the track, and provides strong support for the safe operation of the railway.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
