Description

Technical Field

[0001] This utility model relates to a track enhancement operation equipment, and more particularly to a device for removing laser smoke during track enhancement operations. Background Technology

[0002] In track strengthening operations, using laser head units to emit lasers into the track for strengthening has become an important technical method. Due to its high energy density, lasers can quickly achieve strengthening effects such as hardening and cladding on the track surface, significantly improving the track's wear resistance and fatigue resistance, thereby extending the track's service life and ensuring the safe and stable operation of rail transit.

[0003] However, during the laser-assisted track strengthening process, the interaction between the laser and the track material causes the metal on the track surface to melt and vaporize instantaneously, generating a large amount of smoke. This smoke mainly consists of metal oxides, molten metal particles, and other impurities, and it diffuses rapidly upwards with the hot airflow after it is generated.

[0004] The lenses of the laser head assembly (including focusing lenses and reflecting mirrors) are usually located above or near the laser emission path. Rising smoke easily adheres to the surface of these lenses, causing contamination. Contaminated lenses severely affect the transmission and focusing performance of the laser: on the one hand, contaminants absorb and scatter some laser energy, significantly reducing the effective laser energy reaching the track surface and greatly diminishing the track strengthening effect, failing to achieve the expected strengthening targets; on the other hand, contaminated lenses prevent complete laser penetration, causing some laser energy to be reflected back into the laser head assembly. This reflected laser energy accumulates inside the lens and optical fiber, easily causing localized overheating. This can lead to further lens damage, affecting the normal operation of the laser head assembly, or even directly burn out the lens and connecting optical fiber, causing serious equipment damage, increased maintenance costs and downtime, and potentially posing a safety hazard and a threat to the working environment and personnel safety.

[0005] Therefore, how to effectively remove the laser smoke generated during track strengthening operations and prevent it from contaminating the laser head lens has become a key issue that urgently needs to be addressed to ensure the effectiveness of laser strengthening operations, improve equipment lifespan, and enhance operational safety.

[0017] The preferred technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the first row of laser head groups and the second row of laser head groups are symmetrically arranged in a V-shape with the first lens area and the second lens area on the inner side are located at a high position away from the track.

[0018] The preferred technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: each of the air blowing pipes is installed on the device through a fixing frame, and the fixing frame includes two suspension arms.

[0019] The preferred technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the lower end of the suspension arm is provided with a connecting block that protrudes toward the air blowing pipe, and the connecting block and the air blowing pipe are fastened together by a U-shaped sleeve.

[0021] The area below the first row of laser heads includes the first lens area; the area below the second row of laser heads includes the second lens area.

[0022] The first and second air blowing pipes are positioned far apart from each other directly below the two laser head groups and extend along the length of the laser head groups; the first lens area and the second lens area are located between the first and second air blowing pipes.

[0023] Both the first and second air blowing pipes have air blowing holes on their walls that face the corresponding lens area. One end of the air blowing pipe is provided with a fan interface, and the other end of the air blowing pipe is closed. The fan can selectively achieve sealed communication with the first or second air blowing pipe through a detachable quick-connect structure.

[0024] The preferred technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the bottom surface of the laser head assembly includes a strip-shaped protruding surface for setting lenses and a strip-shaped recessed portion that is concave relative to the strip-shaped protruding surface;

[0025] The air blowing tube is located below the strip-shaped recess, and the air blowing hole is higher than the strip-shaped protrusion.

[0026] The first and second rows of laser head groups are arranged in an arc shape, and their bottom surfaces are symmetrically inclined in a figure-eight shape. The inner strip-shaped protrusions are located at a high position away from the track.

[0028] Compared with existing technologies, the advantages of this invention are: when the blower is sealed and connected to any of the air-blowing pipes, the air-blowing pipe blows airflow through its air-blowing holes to the corresponding lens area, forming an air curtain. This air curtain can simultaneously blow away the smoke generated by the first and second rows of laser head groups from the lens areas of both laser head groups. When the working environment or requirements change, or when it is necessary to clean the other side, simply unplug the quick-connect structure and connect it to the air-blowing pipe on the other side to achieve the same protective effect, but with the airflow direction reversed.

This layout allows the generated smoke to be dispersed by the airflow from both sides to the upper middle, with the shortest path, minimal obstruction, and the most direct and thorough smoke removal effect. By utilizing the airflow generated by a single blower and a single air-blowing pipe, the lenses of both rows of laser heads can be protected simultaneously, achieving extremely high smoke removal efficiency and a dual benefit. Using only one blower, which can be switched to serve both sides, greatly simplifies the air path system and reduces equipment manufacturing costs, energy consumption, and subsequent maintenance costs.

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0037] like Figure 1-3 As shown, this embodiment provides a device 100 for removing laser smoke from track enhancement operations. The device mainly includes two rows of laser head groups 1, two air blowing pipes 2, a fan 3, and corresponding mounting structures. The two rows of laser head groups 1 are arranged in parallel for simultaneously performing laser enhancement operations on the track, such as laser quenching and cladding. Below the laser head groups 1 is a lens area formed by multiple protective lenses 7. Specifically, a first lens area 4 is located below the first row of laser head groups 11, and a second lens area 5 is located below the second row of laser head groups 12.

[0038] like Figure 1-3 As shown, two air blowing pipes 2, namely the first air blowing pipe 21 and the second air blowing pipe 22, are respectively positioned directly below the two sets of laser head groups 1 and are arranged far apart from each other. They extend along the length of the laser head group 1, ensuring coverage of the entire processing area. Crucially, the first lens area 4 and the second lens area 5 are located between the two air blowing pipes 2.

[0039] like Figure 4 As shown, each air blowing pipe 2 has an air blowing hole 6 on its pipe wall, and the air blowing direction of the air blowing hole 6 is towards the lens area between them.

[0040] like Figure 1-3 As shown, the blower 3 can be easily and quickly sealed and connected to one of the air pipes 2 through a detachable quick-connect structure, such as a pagoda connector with a hose clamp or a quick pneumatic connector.

[0041] like Figure 1 , 3As shown, when the device starts operating, the laser head assembly faces the track 200. The operator connects the blower 3 to the first air blowing pipe 21. The strong airflow generated by the blower 3 is blown out through the air blowing holes 6 on the first air blowing pipe 21, forming a directional and continuous air curtain. This air curtain not only blows towards the first lens area 4, but its airflow direction and force are calculated to effectively blow away the metal fumes and splash particles generated by the two rows of laser head assemblies 1 when processing the track, preventing them from adhering to the lenses of the two laser head assemblies. When the working environment or requirements change, or when it is necessary to clean the other side, simply unplug the quick-connect structure and connect it to the second air blowing pipe 22 on the other side to achieve the same protective effect, but with the airflow direction reversed.

[0042] It should be understood that having a separate protective air curtain for each laser head is complex and consumes a large amount of air. This solution places the air blowing pipes 2 directly below the laser head group 1 and far apart from each other, with the lens area in the middle. This layout allows the generated smoke to be dispersed by airflow from both sides towards the center and upwards, resulting in the shortest path, minimal obstruction, and the most direct and thorough smoke removal effect. Utilizing the airflow generated by a single fan 3 and a single air blowing pipe 2, the lenses of both rows of laser heads can be protected simultaneously, achieving extremely high smoke removal efficiency and a dual benefit. Using only one fan 3, which can be switched to serve both sides, greatly simplifies the air path system and reduces equipment manufacturing costs, energy consumption, and subsequent maintenance costs.

[0043] like Figure 1 , 3 As shown, one end of any air blowing pipe 2 is equipped with a fan interface, which can be a threaded interface or a quick-connect interface. The other end of the air blowing pipe 2 is sealed by an end cap or by direct flattening and welding, forming a pipe with only one air inlet, forcing all airflow to be discharged from the air blowing hole 6. This ensures that the outlet pressure of all air blowing holes 6 along the length of the pipe is relatively uniform, thus forming a complete, continuous, and unweak air curtain, avoiding the situation where local airflow is too weak and the smoke protection fails.

[0044] like Figure 1-4 As shown, the air blowing pipe 2 adopts a straight pipe design, which allows for smooth airflow and low pressure loss, thus helping to maintain the stability of the air curtain. Preferably, the side wall of the air blowing pipe 2 has a series of air blowing holes 6 arranged in a straight line with multiple point-separated holes. This method can weave a sufficiently dense air curtain, balancing the uniformity and flow rate of the airflow, while maintaining good mechanical strength of the pipe. Of course, if the side wall of the air blowing pipe 2 has strip-shaped orifice-shaped air blowing holes 6, it can form an absolutely continuous and uninterrupted air curtain, theoretically providing better protection. However, this method may affect the strength of the air blowing pipe 2.

[0045] like Figure 2As shown, the bottom surface of the laser head assembly 1 is not flat, but designed as an irregular structure containing a strip-shaped protrusion 101 and a strip-shaped recess 102. The protective lens 7 is installed inside the strip-shaped protrusion 101. The air blowing pipe 2 is installed in the space below the strip-shaped recess 102. During installation, ensure that the air blowing hole 6 on the air blowing pipe 2 is higher than the strip-shaped protrusion 101, i.e., the plane where the lens is located. The airflow blows from the lower side of the lens towards the area directly in front of the lens. This angle can effectively disperse the smoke that is about to hit the lens and avoid the airflow directly impacting the lens. In addition, this makes full use of the structural space at the bottom of the laser head assembly 1 to hide the installation of the air blowing pipe 2, making the entire device structure very compact and without adding extra volume.

[0046] like Figure 2 As shown, the bottom surfaces of the first row of laser head groups 11 and the second row of laser head groups 12 are not horizontal, but are arranged in a symmetrical "V" shape with an inclination. That is, the inner side of the two laser head groups 1, i.e., the side closer to each other, is higher, and the outer side is lower. Correspondingly, the first lens area 4 and the second lens area 5 on their inner sides are also located at a high position away from the track. Setting the lens areas at a high position and coordinating them with the blowing angle of the air blowing pipe 2 ensures that the upward-drifting smoke is precisely captured and blown away by the horizontally swept air curtain, conforming to the natural movement law of smoke and resulting in higher smoke removal efficiency.

[0047] like Figure 1-3 As shown, the equipment includes a mounting frame 9 on which the blower is mounted. Each air-blowing pipe 2 is installed on the mounting frame via an independent suspension unit. The mounting frame 9 mainly includes two suspension arms 91. The upper end of the suspension arm 91 is fixed to the device frame, and the lower end is used to connect and suspend the air-blowing pipe 2. The two-point suspension support method provides good stability and prevents the long, straight tubular air-blowing pipe 2 from swaying due to vibration or airflow reaction force during operation, ensuring the stability of the air curtain position. At the lower end of the suspension arm 91, there is a connecting block 92 protruding towards the air-blowing pipe 2. The connecting block 92 has threaded holes. A U-shaped fitting 10 is used to hold the air-blowing pipe 2 from below. Both ends of the U-shaped fitting 10 pass through the connecting block 92 and are then tightened with nuts, thus firmly clamping the air-blowing pipe 2 onto the connecting block 92. The suspended installation allows for easy disassembly; simply loosen the connection point at the lower end of the mounting frame 9 to remove the entire air-blowing pipe 2 assembly, facilitating pipe cleaning or replacement and providing excellent maintainability. The U-shaped connector 10 provides strong clamping force, ensuring that the air tube 2 will not loosen in any direction and has excellent vibration resistance. Moreover, this connection method is suitable for air tubes 2 of different diameters. Simply change the diameter of the U-shaped connector 10 to squeeze the tube in. During installation, the angle and height of the air tube 2 can also be finely adjusted to easily adjust to the optimal blowing position.
