Description

Technical Field

[0001] This utility model relates to the field of wheel and axle rust removal technology, specifically a laser rust removal device for wheel and axle rust removal. Background Technology

[0002] With the rapid development of my country's railway industry and the continuous increase in railway line mileage, freight car axles, as a key infrastructure of railway transportation, directly affect the safety and efficiency of railway transport. During long-term use, the surface of the axles gradually corrodes due to environmental factors (such as rain, humidity, and pollutants) and friction and vibration generated by train operation. Axle corrosion not only reduces the mechanical properties of the axles and shortens their service life, but may also lead to problems such as bumps and axle breakage during train operation, seriously threatening railway transportation safety. Currently, the most common wheel and axle rust removal technology is manual rust removal. Manual rust removal mainly relies on workers using tools such as sandpaper and wire brushes to polish by hand. This method is labor-intensive, inefficient, and the rust removal quality is inconsistent. It also cannot completely remove the rust from the wheel and axle surface, resulting in low efficiency and poor quality of wheel and axle rust removal work, and the labor intensity of the operators is also high. Meanwhile, when the axle is rotated for rust removal, it is only placed on the drive wheel to achieve the rotation of the axle. This results in poor stability of the axle during rust removal, and it is easy to misalign, leading to inaccurate rust removal position. This makes the laser rust removal equipment less stable during operation. Furthermore, there is no positioning and limiting at both ends of the axle when it is placed for rust removal, so the position of the two ends of the axle cannot be controlled, resulting in poor accuracy of the axle rust removal. Utility Model Content

[0003] To address the above problems, this utility model provides a laser rust removal device for wheel and axle rust removal, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a laser rust removal device for wheel axle rust removal, comprising a base and a device bracket connected to both sides of the base, wherein a six-axis adjustment mechanism is connected to the device bracket, and a laser rust removal head is connected to one side of the six-axis adjustment mechanism; Two mounting plates are connected to one side of the base, and two fixed seats are connected to the top of each of the two mounting plates. A rotating shaft is connected inside each of the four fixed seats, and a drive wheel is connected to the outside of each of the four rotating shafts. An axle is provided between the four drive wheels. One end of each of the four rotating shafts is connected to a sprocket, and two sprockets on the same side are connected by a chain drive. One side of each of the two fixed seats is connected to a support plate, and the top of the support plate is connected to a motor. The output end of the motor is connected to one end of the rotating shaft.

[0005] Preferably, the top of the base is connected to several support blocks, one side of each support block is connected to a placement groove, and several auxiliary wheels are connected inside the placement groove.

[0006] Preferably, the base is connected to four fixed columns at the top, each fixed column has a movable groove at the top, a rotating column is provided inside the movable groove, and two swing arms are connected to the outside of the rotating column. One end of each swing arm is connected to a drive wheel.

[0008] Preferably, one side of one of the swing arms is connected to a motor three, and the output end of the motor three is connected to one end of the drive wheel.

[0009] Preferably, the six-axis adjustment mechanism includes two fixed housings, which are mounted on the equipment support. A lead screw is connected inside the fixed housing, with one end of the lead screw passing through the equipment support. A motor is connected to one side of the equipment support, and the output end of the motor is connected to one end of the lead screw.

[0010] Preferably, a linear module is provided inside the fixed shell, with both ends of the linear module connected to lead screws, one end of the linear module connected to an electric cylinder, the output end of the electric cylinder connected to a lifting frame, and one side of the lifting frame connected to one side of the laser rust removal head.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application utilizes the movement of a laser rust removal head in conjunction with the automatic rotation of a drive wheel axle to perform automatic rust removal on the axle, eliminating the need for manual rust removal. This solves the problem that current rust removal on axles is mainly done manually, resulting in high labor intensity, low efficiency, and inconsistent rust removal quality. It is beneficial to improve the efficiency and quality of rust removal on axles and reduce the labor intensity of operators. 2. This application uses a rotating column to drive the swing arm to rotate and adjust the active rotating wheel to one side of the wheel axle, so that the active rotating wheel presses and limits the wheel axle and drives the wheel axle to rotate to remove rust. This solves the problem that the wheel axle is not stable when rotating to remove rust and is prone to misalignment, which leads to inaccurate rust removal position. This is beneficial to improving the stability of laser rust removal equipment during operation. 3. This application uses a connecting arm and a limiting wheel to limit both ends of the axle when the drive wheel is adjusted to press the axle, without affecting the normal rotation of the axle. This solves the problem of not positioning and limiting both ends of the axle when it is placed for rust removal, and helps to improve the accuracy of axle rust removal. Attached Figure Description

[0014] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0015] Example 1: Please refer to Figures 1 to 3 A laser rust removal device for wheel axle includes a base 1 and a device bracket 2 connected to both sides of the base 1. A six-axis adjustment mechanism 3 is connected to the device bracket 2. A laser rust removal head 4 is connected to one side of the six-axis adjustment mechanism 3. The six-axis adjustment mechanism 3 will drive the laser rust removal head 4 to move in six directions above the wheel axle. The laser generator inside the laser rust removal head 4 will emit a high-energy pulsed laser with a specific wavelength (commonly 1064nm). After the beam is focused by the focusing lens, it will accurately irradiate the rust layer on the surface of the wheel axle. The absorption rate of the rust layer to laser energy is much higher than that of the metal substrate. It will quickly absorb the laser energy and instantly heat up to thousands of degrees Celsius. At high temperatures, the rust layer will rapidly vaporize, melt, or thermally expand. The thermal shock generated by the rapid change in volume will damage the structural integrity of the rust layer. At the same time, the micro-explosions and shock waves caused by high temperatures will further weaken the bonding force between the rust layer and the metal substrate of the wheel axle, causing the rust layer to peel off directly from the surface of the wheel axle substrate. Moreover, the metal substrate of the wheel axle has a high reflectivity to lasers, absorbs very little energy, and the laser action time is extremely short (microseconds, nanoseconds). Heat will not be conducted into the interior of the wheel axle substrate, thus avoiding damage such as deformation and annealing of the wheel axle substrate. The laser rust removal head 4, together with the six-axis adjustment mechanism 3 and the rotation of the wheel axle, enables the laser beam to scan evenly along a preset path, achieving precise rust removal on different parts of the wheel axle. Furthermore, by adjusting the laser power and scanning speed, it can adapt to cleaning needs with different degrees of rust. Two mounting plates 5 are connected to one side of the base 1. Two fixed seats 6 are connected to the top of each of the two mounting plates 5. A rotating shaft 7 is connected inside each of the four fixed seats 6. A drive wheel 8 is connected to the outside of each of the four rotating shafts 7. An axle is set between the four drive wheels 8. When removing rust from the axle, the personnel place the axle on the four drive wheels 8. Due to the influence of the weight of the axle, the axle presses against the drive wheel 8. Thus, when the drive wheel 8 rotates, it will drive the axle to rotate on the drive wheel 8. Specifically, the output end of motor 11 drives the rotating shaft 7 to rotate inside the fixed base 6. When the rotating shaft 7 rotates, it drives the external sprocket 9 to rotate. At this time, the sprocket 9 drives another rotating shaft 7 on the same side to rotate synchronously through the chain, thereby achieving synchronous rotation of the rotating shaft 7. Because the rotating shaft 7 also drives the drive wheel 8 to rotate inside the fixed base 6 when it rotates, the synchronous rotation of the four drive wheels 8 will drive the wheel axle to rotate, achieving comprehensive rust removal of the wheel axle. This solves the problem that the current rust removal of wheel axles is mainly done manually, which results in high labor intensity, low efficiency and inconsistent rust removal quality. It is beneficial to improve the efficiency and quality of wheel axle rust removal and reduce the labor intensity of operators. One end of each of the four rotating shafts 7 is connected to a sprocket 9. Two sprockets 9 on the same side are connected by a chain drive. One side of each of the two fixed seats 6 is connected to a support plate 10. The top of the support plate 10 is connected to a motor 11. The output end of the motor 11 is connected to one end of the rotating shaft 7.

[0016] Example 2: Please refer to Figures 4 to 7 The top of the base 1 is connected to several support blocks 12. One side of the support block 12 is connected to a placement groove 13. Several auxiliary wheels 14 are connected inside the placement groove 13. When the axle is being derusted, it needs to be placed in the placement groove 13. At this time, the outer side of the axle will contact the auxiliary wheel 14 at the bottom of the placement groove 13. When the axle rotates, it will drive the auxiliary wheel 14 to rotate, thereby ensuring that the axle can rotate and derust in the placement groove 13.

[0017] The top of the base 1 is connected to four fixed columns 15. The top of the fixed columns 15 is provided with a movable groove 16. The movable groove 16 is provided with a rotating column 17. The outside of the rotating column 17 is connected to two swing arms 18. One end of the two swing arms 18 is connected to a drive wheel 19. The output end of the motor 21 drives the rotating column 17 to rotate, so that the rotating column 17 drives the swing arms 18 and the drive wheel 19 to rotate. Specifically, the drive wheel 19 rotates to the upper part of the wheel axle. In this way, the four drive wheels 19 will press the upper sides of both ends of the wheel axle. With the help of several auxiliary wheels 14 at the bottom of the wheel axle, the rotation of the wheel axle is realized. This solves the problem of poor stability of the wheel axle during rotational rust removal and easy misalignment, which leads to inaccurate rust removal position. It is beneficial to improve the stability of the laser rust removal equipment during operation. More specifically, the output end of motor 320 drives the active rotating wheel 19 to rotate, which in turn drives the wheel axle to rotate, thus achieving comprehensive rust removal of the wheel axle; In addition, when the rotating column 17 drives the driving wheel 19 to rotate to the upper part of the wheel axle, it will also drive the connecting arm 22 and the limiting wheel 23 to rotate to both ends of the wheel axle. In this way, the four limiting wheels 23 will be located at both ends of the wheel axle, thereby achieving positioning and restriction of both ends of the wheel axle. Please see Figure 8 It should be added that when the limiting wheel 23 limits both ends of the wheel axle, the end of the wheel axle will rotate and cooperate with the end of the limiting wheel 23. In this way, the limiting wheel 23 will also rotate while the wheel axle rotates, so as to limit both ends of the wheel axle and maintain the normal rotation of the wheel axle. It is important to note that before the axle is placed into the placement slot 13, the rotating column 17 drives the driving wheel 19 and the limiting wheel 23 to rotate and adjust to one side, which will not affect the normal placement of the axle into the placement slot 13. After the axle is placed into the placement slot 13, the rotating column 17 works to drive the driving wheel 19 and the limiting wheel 23 to rotate and adjust to the appropriate position. In this way, the limiting wheel 23 will limit both ends of the axle without affecting the normal rotation of the axle. This solves the problem that the axle was not positioned and limited at both ends when it was placed for rust removal, which helps to improve the accuracy of rust removal of the axle.

[0018] One side of the fixed column 15 is connected to a motor 21. The output end of the motor 21 is connected to one end of the rotating column 17. The other end of the rotating column 17 is connected to a connecting arm 22. One end of the connecting arm 22 is connected to a limit wheel 23.

[0019] One side of one of the swing arms 18 is connected to a motor 20, and the output end of the motor 20 is connected to one end of the drive wheel 19.

[0020] The six-axis adjustment mechanism 3 includes two fixed housings 301, which are mounted on the equipment support 2. A lead screw 302 is connected inside the fixed housing 301. One end of the lead screw 302 passes through the equipment support 2. A motor 303 is connected to one side of the equipment support 2. The output end of the motor 303 is connected to one end of the lead screw 302. The output end of the motor 303 drives the lead screw 302 to rotate, which causes the linear module 304 to drive the laser rust removal head 4 to move in the back-and-forth direction. At the same time, the linear module 304 will also drive the electric cylinder 305 and the laser rust removal head 4 to move in the left and right directions. It should be noted that the current technology of the linear module 304 and the electric cylinder 305 is very mature and is well known. Those skilled in the art can and should understand their specific functions and structures, so they will not be described in detail here. Furthermore, the output end of the electric cylinder 305 will drive the lifting frame 306 and the laser rust removal head 4 to move in the vertical direction; In summary, the six-axis adjustment mechanism 3 can drive the laser rust removal head 4 to move in six directions, thereby ensuring that the laser rust removal head 4 moves above the axle and works in conjunction with the rotation of the axle to perform comprehensive rust removal on the axle.

[0021] The fixed housing 301 is equipped with a linear module 304. Both ends of the linear module 304 are connected to the lead screw 302. One end of the linear module 304 is connected to the electric cylinder 305. The output end of the electric cylinder 305 is connected to the lifting frame 306. One side of the lifting frame 306 is connected to one side of the laser rust removal head 4.

[0022] When using this utility model: Firstly, in Example 1, when removing rust from the axle, the operator places the axle on four drive wheels 8. Due to the weight of the axle, it presses against the drive wheels 8, causing the axle to rotate as the drive wheels 8 rotate. Specifically, the output of motor 11 drives the rotating shaft 7 to rotate inside the fixed base 6. When the rotating shaft 7 rotates, it drives the external sprocket 9 to rotate. At this time, the sprocket 9 drives another rotating shaft 7 on the same side to rotate synchronously via a chain, thus achieving synchronous rotation of the rotating shaft 7. Because the rotation of the rotating shaft 7 also drives the drive wheels 8 to rotate inside the fixed base 6, the synchronous rotation of the four drive wheels 8 drives the axle to rotate, achieving comprehensive rust removal from the axle. This solves the problem that the current rust removal of axles is mainly done manually, resulting in high labor intensity, low efficiency, and inconsistent rust removal quality. It is beneficial to improve the efficiency and quality of axle rust removal and reduce the labor intensity of operators. Secondly, the laser rust removal head 4, together with the six-axis adjustment mechanism 3 and the rotation of the wheel axle, enables the laser beam to scan evenly along a preset path, achieving precise rust removal on different parts of the wheel axle. Furthermore, by adjusting the laser power and scanning speed, it can adapt to cleaning needs with different degrees of rust. Then, in Embodiment 2, the axle needs to be placed in the placement groove 13 during rust removal. At this time, the outer side of the axle will contact the auxiliary wheel 14 at the bottom of the placement groove 13. When the axle rotates, it will drive the auxiliary wheel 14 to rotate, thereby ensuring that the axle can rotate and remove rust in the placement groove 13. The output end of the motor 21 drives the rotating column 17 to rotate, so that the rotating column 17 drives the swing arm 18 and the active rotating wheel 19 to rotate. Specifically, the active rotating wheel 19 rotates to the upper part of the axle. In this way, the four active rotating wheels 19 will press the upper sides of both ends of the axle, and cooperate with the several auxiliary wheels 14 at the bottom of the axle to realize the rotation of the axle. This solves the problem of poor stability of the axle during rotational rust removal and easy misalignment, which leads to inaccurate rust removal position. This is beneficial to improving the stability of the laser rust removal equipment during operation. Finally, the output of motor 20 drives the drive wheel 19 to rotate, causing the drive wheel 19 to rotate the axle, thus achieving comprehensive rust removal of the axle. In addition, when the rotating column 17 drives the drive wheel 19 to rotate to the upper part of the axle, it also drives the connecting arm 22 and the limiting wheel 23 to rotate to both ends of the axle. In this way, the four limiting wheels 23 will be located at both ends of the axle, achieving positioning and restriction at both ends of the axle. It is important to note that before the axle is placed into the placement slot 13, the rotating column 17 drives the drive wheel 19 and the limiting wheel 23 to rotate and adjust to one side, which will not affect the normal placement of the axle into the placement slot 13. After the axle is placed into the placement slot 13, the rotating column 17 drives the drive wheel 19 and the limiting wheel 23 to rotate and adjust to the appropriate position.
