Description

Technical Field

[0001] This utility model relates to a metal surface strengthening treatment device, and more particularly to a wheel strengthening treatment device for rail vehicles, used to strengthen the surface of rail vehicle wheels. Background Technology

[0002] Rail vehicles such as trains, subways, and light rail typically have wheels made of metal. After running for a certain number of kilometers, the areas where the wheels contact the rails experience significant wear. When the wheels wear down to a certain extent, wheel repair is necessary. Furthermore, when the wear reaches a certain standard, the wheels must be scrapped and replaced.

[0003] On the other hand, rail vehicles are typically subject to a major overhaul cycle. For example, heavy-haul freight trains generally require a major overhaul after 1 million kilometers of operation. Whether it is a major overhaul or wheel repair and replacement, the rail vehicle needs to be taken out of service for a period of time, and the amount of maintenance work is usually quite large.

[0004] However, the asynchronous maintenance cycles of wheels and the entire vehicle have become a major challenge for rail vehicle operation and maintenance. For example, the aforementioned heavy-haul freight train requires a major overhaul after 1 million kilometers of operation, while wheels typically need to be scrapped and replaced after only 600,000 to 700,000 kilometers. This asynchrony between the two maintenance cycles means that the downtime for rail vehicle maintenance must be calculated using the least common multiple of the two, increasing the frequency of maintenance and consuming significant time, manpower, and material resources.

[0005] The invention patent application with publication number CN117947416A discloses a track laser enhancement integrated processing device and a track strengthening processing method. The track laser enhancement integrated processing device travels on a track section, and a heating head, a spray gun head, and a laser head arranged sequentially on the underside of the device pass through the track section in sequence. After the heating head heats the surface of the track section, the spray gun head sprays a strengthening material onto the heated surface of the track section. The laser emitted by the laser head scans the track section sprayed with the strengthening material, causing the alloy coating to undergo a metallurgical chemical reaction with the surface structure of the track, forming a strengthening layer on the surface of the track.

[0006] However, the track is static, independent, and linearly laid on the ground, while the wheels of the rail vehicles are installed at the bottom of the vehicle and mounted on the track. There are many of them, and they need to be processed one by one. The surface enhancement treatment of the track and the wheels requires two completely different operating methods. This kind of track laser enhancement integrated processing equipment cannot directly perform surface enhancement treatment on the wheels of rail vehicles. It is necessary to design enhancement processing equipment separately according to the characteristics of the wheels of rail vehicles. Summary of the Invention

[0007] Given that the wheels of rail vehicles wear out quickly, causing their maintenance cycle to be out of sync with that of the entire vehicle, resulting in an increased frequency of rail vehicle downtime for maintenance, and that existing rail laser enhancement integrated processing equipment cannot be directly applied to the wheels of rail vehicles, the technical problem to be solved by this utility model is to provide a wheel enhancement processing device for rail vehicles, which performs surface enhancement processing on the wheels according to their characteristics, thereby extending the wheel maintenance cycle and enabling it to be coordinated with the overall vehicle maintenance cycle.

The servo motor drives the drive wheel to rotate. The drive wheel is used to drive the opposite wheel of the wheel to be processed to rotate, thereby driving the wheel to be processed to rotate. The spraying mechanism includes a material tank, a feeding pipe and a spray gun. The feeding pipe is used to transport the reinforcing coating in the material tank to the spray gun, and the spray gun is used to spray the reinforcing coating onto the surface of the wheel to be treated. The laser mechanism includes a laser head and a laser generator. The laser generator produces laser light, and the laser head is used to emit laser light onto the surface of the wheel to be treated, which is coated with reinforcing paint, to perform the reinforcing operation.

[0009] The preferred technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the vehicle lifting mechanism includes a pair of lifting frames, which are respectively arranged on both sides of the wheelset to be processed.

[0012] The preferred technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the driving mechanism further includes a clamping component disposed on the upper side of the first mounting base; The clamping assembly includes a spring, a slide rail, and a slider; the slider is disposed on the slide rail and can slide along the slide rail; the drive wheel and the servo motor are disposed on the slider; the spring presses against the slider to make the outer peripheral surface of the drive wheel press against the outer peripheral surface of the opposite wheel of the wheel to be processed.

[0013] The preferred technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an electromagnetic valve is installed on the material barrel of the spraying mechanism to receive start and stop commands, so as to automatically control the start and stop of the spraying of the spray gun.

[0014] The preferred technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the laser mechanism further includes a laser control cabinet and a chiller; The laser control cabinet houses the laser generator, system control components, and an operation panel, with an automatic operation button on the operation panel.

[0018] Compared with existing technologies, the advantages of this invention are: it achieves surface enhancement treatment of rail vehicle wheels through its four functional modules: a vehicle lifting mechanism simultaneously lifts the heavy wheelset to be treated off the track; a drive mechanism indirectly drives the wheel to be treated by rotating the opposite wheel, thus avoiding obstruction to the spraying and laser operations; a spraying mechanism sprays surface enhancement coating onto the rotating wheel; and a laser mechanism performs laser treatment on the sprayed wheel.

Consequently, the lifespan of rail vehicle wheels reaches approximately 1 million kilometers, synchronizing with the overall vehicle overhaul cycle. By utilizing the same wheel maintenance and replacement plan as the overall vehicle overhaul shutdown plan, the maintenance and repair costs of rail vehicles are significantly reduced.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1 The diagram shows the wheel reinforcement processing equipment 100 for a rail vehicle provided in this embodiment, performing wheel reinforcement processing on a wheel 201c of one of the cars 200 of the rail vehicle. As can be seen, this car 200 has four wheels 201. The two front wheels 201 are coaxially connected, forming one wheelset, and the two rear wheels 201 are coaxially connected, forming another wheelset. Let's assume the wheelset containing the wheel 201c to be processed is wheelset 202c for clarity of description.

[0024] When the carriage 200 is parked on the track r, the four wheels 201 rest on the track r. When performing wheel reinforcement treatment on any wheel 201, since the two wheels 201 of the same wheelset are coaxially connected, the wheelset must be lifted off the track r at the same time.

[0025] like Figure 1 As shown, the wheel reinforcement treatment equipment 100 for rail vehicles provided in this embodiment has four major functional modules, including: a first functional module: a vehicle lifting mechanism 10; a second functional module: a drive mechanism 20; a third functional module: a spraying mechanism 30; and a fourth functional module: a laser mechanism 40.

[0026] Combination Figures 2 to 6As shown, the vehicle lifting mechanism 10 is used to lift the wheelset 202c to be processed off the track r. The drive mechanism 20 includes a servo motor 21 and a drive wheel 22. The servo motor 21 is connected to the drive wheel 22. The outer circumferential surface of the drive wheel 22 is used to press against the outer circumferential surface of the opposite wheel 201d of the wheelset 201c to be processed. The servo motor 21 drives the drive wheel 22 to rotate, and the drive wheel 22 drives the opposite wheel 201d of the wheelset 201c to rotate. Since the two wheels 201 of the same wheelset are coaxially connected, the wheelset 201c to be processed can be driven to rotate. The drive mechanism 20 drives the opposite wheel 201d of the wheelset 201c to rotate, thereby indirectly driving the wheelset 201c to rotate, which can prevent the drive mechanism 20 from obstructing the operation of the spraying mechanism 30 and the laser mechanism 40.

[0027] The spraying mechanism 30 includes a material tank 31, a feeding pipe 32, and a spray gun 33. The feeding pipe 32 is used to transport the reinforcing paint in the material tank 31 to the spray gun 33, and the spray gun 33 is used to spray the reinforcing paint onto the surface of the wheel 201c to be treated. The laser mechanism 40 includes a laser head 41 and a laser generator (not shown in the figure). The laser generator generates laser j, and the laser head 41 is used to emit laser j onto the surface of the wheel 201c to be treated, which has been sprayed with reinforcing paint, to perform the reinforcing operation.

[0028] As can be seen, the wheel reinforcement treatment equipment for rail vehicles provided by this utility model achieves surface reinforcement treatment of rail vehicle wheels through its four functional modules: a vehicle lifting mechanism simultaneously lifts the heavy wheelset to be treated off the track; a drive mechanism drives the wheel to be treated to rotate indirectly by driving the opposite wheel of the wheel to be treated, thus avoiding obstruction to the spraying and laser operations; a spraying mechanism sprays surface reinforcement coating onto the rotating wheel to be treated; and a laser mechanism performs laser treatment on the sprayed wheel to be treated. These four functional modules work together to efficiently complete the wheel reinforcement treatment operation for rail vehicles.

[0029] This enhances the surface hardness, toughness, and wear resistance of rail vehicle wheels, increasing their lifespan by 2-3 times within the wear-resistant layer. Consequently, the lifespan of rail vehicle wheels reaches approximately 1 million kilometers, synchronizing with the overall vehicle overhaul cycle. By utilizing the same wheel maintenance and replacement plan as the overall vehicle overhaul shutdown plan, the maintenance and repair costs of rail vehicles are significantly reduced.

[0030] Let's take a closer look at the four main functional modules: like Figure 1As shown, the vehicle lifting mechanism 10 includes a pair of lifting frames 11, which are respectively positioned on both sides of the wheelset 202c to be processed. Each lifting frame 11 is used to lift one side of the rail vehicle to lift the wheelset 202c to be processed off the track r. In this embodiment, the lifting frame 11 is located below the connection structure between the car body 200 and the wheelset 201c to be processed, and the wheelset 202c to be processed is lifted by lifting the connection structure. Of course, the connection structure between the car body and the wheels varies for different rail vehicles, and the lifting position can be adjusted as needed.

[0031] like Figure 2 and Figure 3 As shown, the drive mechanism 20 also includes a fixing component 50. The fixing component 50 includes a first mounting base 51, and a positioning block 52, a clamping block 53, and a quick clamp 54 fixed to the lower side of the first mounting base 51, wherein the quick clamp 54 is connected to the clamping block 53, and the clamping block 53 is located at the front end of the quick clamp 54. The drive wheel 22 and the servo motor 21 are disposed on the upper side of the first mounting base 51.

[0032] During installation, the positioning block 52 is used to position one side of the track r, and the quick clamp 54 is used to drive the clamping block 53 to press against the other side of the track r, so as to clamp and fix the first mounting base 51 on the track r, thereby positioning and fixing the drive mechanism 20 at a specific position in the length direction of the track r.

[0033] Furthermore, such as Figure 2 As shown, the drive mechanism 20 also includes a clamping assembly 60 disposed on the upper side of the first mounting base 51. The clamping assembly 60 includes a spring 61, a slide rail 62, and a slider 63. The slide rail 62 is disposed along the width direction of the track r, and the slider 63 is disposed on the slide rail 62 and can slide along the slide rail 62. The drive wheel 22 and the servo motor 21 are disposed on the slider 63. The spring 61 presses against the slider 63, causing the outer circumferential surface of the drive wheel 22 to press against the outer circumferential surface of the opposite wheel 201d of the wheel 201c to be processed. Because the spring 61 presses against the slider 63 in real time, the outer circumferential surface of the drive wheel 22 presses against the outer circumferential surface of the opposite wheel 201d of the wheel 201c to be processed in real time, ensuring sufficient friction between them and ensuring driving force and driving efficiency.

[0034] In this embodiment, a top pressure side plate 55 is vertically provided on the outer side of the first mounting base 51, the outer end of the spring 61 acts on the top pressure side plate 55, and the inner end of the spring 61 acts on the slider 63.

[0035] like Figure 4As shown, the spraying mechanism 30 has an electrical device 2, such as a solenoid valve 34, installed on the material tank 31 to receive start and stop commands, automatically controlling the spray gun 33 to start and stop spraying. During spraying, the spray gun 33 remains stationary while the wheel 201c to be treated rotates. When the spraying mechanism 30 receives a spraying command, the spray gun 33 automatically starts spraying and stops spraying after a specified time. In this embodiment, the spray gun 33 is configured to radiate the reinforcing coating at a certain angle to form a fan-shaped spray surface f on the surface of the wheel 201c to be treated, and the specified spraying time is set to the time required for the wheel 201c to rotate one revolution.

[0036] like Figure 5 As shown, the laser mechanism 40 also includes a laser control cabinet 42 and a chiller 43. The laser control cabinet 42 houses a laser generator (not shown), system control components (not shown), and an operation panel (not shown). The operation panel has an automatic operation button. The operation panel and system control components are used to control the operation of the entire wheel enhancement treatment equipment 100 of the rail vehicle. The chiller 43 cools the laser generator and laser head 41.

[0037] Laser head 41 is responsible for emitting light. After spraying is completed, the wheel 201c to be treated continues to rotate at a constant speed, and laser head 41 emits light to initiate the laser enhancement operation on the wheel. Laser head 41 is configured to control the translation and jumping of the laser spot. In this embodiment, laser head 41 is used to form a surface on the wheel 201c to be treated such as... Figure 7 The annular reinforcement band d shown: After the wheel 201c to be processed rotates one revolution, the laser head 41 stops emitting light, that is, a reinforcement band is completed on the surface of the wheel 201c to be processed. Subsequently, the laser head 41 automatically controls the light spot to translate and jump horizontally to the next light emission point to continue emitting light until all annular reinforcement bands d are completed. In other embodiments, the laser head 41 can also be configured to form dot-shaped reinforcement bands and spiral reinforcement bands on the surface of the wheel 201c to be processed.

[0038] like Figure 5 As shown, the laser head 41 is connected to the laser control cabinet 42 via optical fiber 44 to improve the information transmission rate.

[0039] like Figure 6 As shown, the laser mechanism 40 also includes a second mounting base 45. The second mounting base 45 is used to fix the laser head 41 on the upper side of the second mounting base 45. The second mounting base 45 can be fixed by a quick clamping method similar to that of the first mounting base 51, or by other fixing methods such as bolt tightening.

[0040] The laser head 41 is fixed to the upper side of the second mounting base 45 by an angle adjustment device 46. The angle adjustment device 46 adjusts the pitch angle of the laser head 41 to change the angle between the laser and the surface of the wheel 201c to be treated, thereby obtaining the highest laser utilization rate.

[0041] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0042] The wheel reinforcement processing equipment for rail vehicles provided by this utility model has been described above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principle, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
