Description

Technical Field

[0001] This utility model relates to the field of laser cleaning, and in particular to a special track for laser low-temperature cleaning of high-speed rail wheelsets. Background Technology

[0002] High-speed rail wheelsets require regular maintenance. In recent years, laser cleaning has gradually replaced traditional cleaning methods and gained a foothold in this field. However, existing laser cleaning methods are prone to generating thermal effects, which can cause damage such as cracks on the surface of wheelset materials. Therefore, there is an urgent need for a new type of low-temperature laser cleaning method that is less likely to generate thermal effects, as well as supporting special equipment. Summary of the Invention

[0003] The purpose of this invention is to propose a special track for low-temperature laser cleaning of high-speed rail wheelsets, in order to solve the technical problems existing in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dedicated track for laser low-temperature cleaning of high-speed rail wheelsets, comprising a core moving track and fixed tracks connected at both ends. The fixed tracks are supported by lower fixed track pillars, the lower ends of which are connected to a base. The moving track is connected to a moving track pillar below, and the lower ends of the moving track pillars are connected to one side of the base via a base rotating joint. The other side of the base is connected to a trackless pillar via another set of base rotating joints. A rotating joint is provided at the connection between the moving track pillar and the moving track, allowing temporary connection to the upper end of the trackless pillar via the rotating joint. The moving track pillar, trackless pillar, and base are arranged in a triangular pattern in cross-section. After releasing the rotating joint between the moving track pillar and the trackless pillar, the moving track pillar and the trackless pillar can swing to near the ground via their respective lower base rotating joints. A transparent water tank is placed above a water tank platform, which is fixed above the base by telescopic pillars. The water tank and the water tank platform can move up and down via the telescopic pillars. A rectangular gap is provided in the middle of the water tank platform, allowing the laser directly below to pass through the platform and enter the water tank.

[0005] Furthermore, the water tank has a set of vertically distributed T-shaped grooves on each of the two inner sides perpendicular to the movement track for inserting lenses. A rectangular frame is provided on the inner side of the bottom of the water tank, in which lenses can be placed to restrict the movement of the lenses in the horizontal direction. There are notches on both sides of one set of opposite sides of the rectangular frame for removing the lenses. The laser incident direction is perpendicular to the movement track and towards the inside of the water tank, and perpendicular to the bottom of the water tank and upward. The three laser incident directions correspond to the three lenses installed.

[0006] Furthermore, the telescopic support can be lifted by a hydraulic system or by a motor.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] The hub and flange of high-speed rail wheelsets can be cleaned without disassembling the wheelsets, which can shorten the cleaning cycle; low-temperature cleaning using laser-induced cavitation technology can reduce the laser thermal effect and avoid surface damage caused by the thermal effect.

[0017] Reference Figure 1This utility model provides a special track for laser low-temperature cleaning of high-speed rail wheelsets, including a core moving track 8 and fixed tracks 9 connected at both ends. The fixed track 9 is supported by a fixed track pillar 10 below, and the lower end of the fixed track pillar 10 is connected to the base 1. The moving track 8 is connected to a moving track pillar 3 below. The lower end of the moving track pillar 3 is connected to one side of the base 1 through a base rotating joint 2. The other side of the base 1 is connected to a trackless pillar through another set of base rotating joints 2. A rotating joint is provided at the connection between the moving track pillar 3 and the moving track 8, which can be temporarily connected to the upper end of the trackless pillar 6 through the rotating joint. The moving track pillar 3, the trackless pillar 6 and the base 1 are triangularly distributed in cross-section. After the rotating joint between the moving track pillar 3 and the trackless pillar 6 is released, the moving track pillar 3 and the trackless pillar 6 can swing to the vicinity of the ground through the base rotating joints 2 at their respective lower ends. A transparent water tank 7 is placed on top of a water tank platform 5. The water tank platform 5 is fixed to the base 1 by a telescopic pillar 4. The water tank 7 and the water tank platform 5 can move up and down through the telescopic pillar 4, which is lifted by a hydraulic system.

[0018] refer to Figure 2 The water tank platform 5 has a rectangular gap 11 in the middle, which allows the laser directly below to pass through the water tank platform 5 and enter the water tank 7.

[0019] refer to Figure 1 , Figure 3 and Figure 4 The inner sides of the water tank 7 in two directions perpendicular to the motion track 8 are provided with a set of vertically distributed T-shaped grooves 12 for inserting lenses 14. The inner bottom of the water tank 7 is provided with a rectangular frame 13, in which the lenses 14 can be placed to restrict the horizontal movement of the lenses 14. One set of opposite sides of the rectangular frame 13 has notches on both sides for removing the lenses 14. The laser incident direction 21 is perpendicular to the motion track 8 towards the inside of the water tank 7 and perpendicular to the bottom of the water tank 7 upward. The three laser incident directions 21 correspond to the three lenses 14 installed.

[0020] Based on the above device, its corresponding operating steps are as follows: S1, in the non-working state, the train passes through the cleaning area, with one side of the wheelset to be cleaned directly above the water tank 7; S2, the rotating joint between the motion track 8 and the trackless support 6 is released; S3, the motion track 8 and the trackless support 6 are swung to near the ground; S4, the water tank platform 5 and the water tank 7 are raised by the telescopic support 4, so that the lower half of the wheel flange hub on one side of the wheelset is submerged in the liquid in the water tank 7; S5, laser-induced cavitation technology is used to start laser underwater low-temperature cleaning, during which the wheelset is rotated to clean the entire area; S6, after cleaning is completed, the water tank 7 is lowered by the telescopic support 4; S7, the motion track 8 and the trackless support 6 are raised to the non-working position and the motion joint is connected; S8, the train moves forward.

[0021] This invention utilizes laser-induced cavitation technology for low-temperature cleaning, which can reduce the laser thermal effect, avoid surface damage caused by the thermal effect, and clean the hub and flange of high-speed rail wheelsets without disassembling the wheelsets, thus shortening the cleaning cycle.
