Description

Technical Field

[0001] The utility model relates to the technical field of rail strengthening equipment, in particular to a rail plasma surface strengthening treatment device. Background Art

[0002] With the continuous increase in the volume of domestic railway lines, the continuous development of railway transportation towards high speed and heavy load, the increase in train speed requires the rails to have a higher smoothness. Heavy loads accelerate the side wear, vertical wear and wave wear of the rails. In order to improve the service life, surface hardness and wear resistance of turnout rails to meet the requirements of high-speed and heavy-load railways, the rails need to be strengthened. In the process of strengthening the surface of the rail, a laminar plasma beam is usually used to instantly heat the surface of the rail, so that the surface temperature of the rail reaches above the critical point of austenite phase transformation and below the melting point, and then the rail itself is rapidly cooled by its own good thermal conductivity, so that ultra-fine, uniform and substrate interface clear needle-shaped martensite and residual austenite complex structures are formed on the surface of the rail head, which improves the surface hardness and wear resistance of the rail.

[0003] However, in the existing process of strengthening rails by plasma, since laminar plasma will quickly heat the rails and make the rails reach a very high temperature, there is no suitable and corresponding method to cool the rails, and it is necessary to wait for the temperature of the rails to drop before performing subsequent operations, which affects production efficiency. In addition, due to the irregular shape of the rails, the rails need to be heated from different angles. The existing devices are not convenient when adjusting the angles. Therefore, there is an urgent need for rail surface strengthening equipment that can solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1 A rail plasma surface strengthening treatment device shown in the figure includes a support frame 1, on which a conveying roller 17 is arranged, and the conveying roller 17 is used to convey the rail. A horizontally slidable movable frame 2 is provided on the upper surface of one end of the support frame 1, and an ion generator 3 is provided on the inner wall of the movable frame 2. An adjustment mechanism is provided on one side of the ion generator 3, and the adjustment mechanism is used to adjust the angle of the ion generator 3.

[0021] The support frame 1 is provided with a support plate 4 and an adjustment plate 5 in sequence along the conveying direction of the conveyor roller 17. The support plate 4 and the adjustment plate 5 are both door-shaped structures composed of a horizontally arranged transverse plate and vertically arranged vertical plates fixed at both ends of the transverse plate, and the two are arranged at intervals. A cooling plate 6 is connected to the lower part of the transverse plate of the support plate 4 through a rotating shaft. The cooling plate 6 is located above the conveyor roller 17. A nozzle 7 is provided at the bottom of the cooling plate 6. A water inlet pipe 10 is fixedly connected to the upper surface of the transverse plate of the support plate 4. The water inlet pipe 10 is communicated with the cavity inside the cooling plate 6. A threaded rod 8 is connected between the two vertical plates of the adjustment plate 5, and a wiper 9 is provided at one end of the threaded rod 8.

[0022] The movable frame 2 can slide on the supporting frame 1, and the position of the movable frame 2 can be adjusted. The adjusting mechanism can adjust the angle of the ion generator 3. The cooling plate 6 is arranged at the bottom of the supporting plate 4 and can be rotated at the bottom of the cooling plate 6. The coolant in the water inlet pipe 10 can flow into the cooling plate 6 and be sprayed out from the nozzle 7 to cool the rail below. During the rotation of the threaded rod 8, the position of the wiper plate 9 can be adjusted to facilitate the wiper plate 9 to be pressed against the rail to better scrape off the coolant remaining on the rail. The threaded rod 8 is arranged between the vertical plates of the adjusting plate 5 and spans above the conveyor roller 17, which can better scrape off the coolant remaining on the rail.

[0023] In this embodiment, Figure 2 and 3 As shown, the adjustment mechanism includes a protective shell 11, a limiting rod 12 and a ratchet 13. The protective shell 11 is fixedly connected to one side of the ion generator 3. The limiting rod 12 is arranged on one side of the protective shell 11 through a rotating shaft. The ratchet 13 is rotatably arranged inside the protective shell 11. One end of the limiting rod 12 is in contact with the outer surface of the ratchet 13. An adjusting nut 14 is provided on the surface of the protective shell 11. One end of the adjusting nut 14 is fixedly connected to the surface of the ratchet 13. The back of the ratchet 13 is fixedly connected to the surface of the ion generator 3. A tension spring 15 is provided inside the protective shell 11. One end of the tension spring 15 is fixedly connected to the inner wall of the protective shell 11, and the other end of the tension spring 15 is fixedly connected to the surface of the limiting rod 12.

[0024] When the adjusting nut 14 is rotated, the adjusting nut 14 will drive the ion generator 3 at one end to rotate together to adjust the irradiation angle of the ion generator 3. The tension spring 15 moves the limit rod 12 toward one end of the ratchet 13. After the limit rod 12 is engaged with the ratchet 13, the angle of the adjusting nut 14 can be fixed, thereby fixing the angle of the ion generator 3. When the limit rod 12 is pried outward, the limit rod 12 is separated from the ratchet 13, thereby adjusting the angle of the adjusting nut 14.

[0025] In this embodiment, a support leg 16 is provided at the bottom of the support frame 1, and a water collecting pan 18 located below the conveyor roller 17 is provided on one side of the support leg 16. The water collecting pan 18 is located below the cooling plate. The coolant sprayed from the nozzle 7 falls on the heated rail, and falls to the bottom after cooling the rail. The scraper 9 can scrape off the coolant remaining on the surface of the rail, and the coolant falls into the water collecting pan 18 at the bottom. A drain pipe is provided on the water collecting pan 18, and the coolant is discharged through the drain pipe and reused.

[0026] In this embodiment, a through hole 19 is provided on the upper surface of the mobile frame 2, and the top of the ion generator 3 is slidably connected to the inner wall of the through hole 19. The sliding between the mobile frame 2 and the support frame 1 is achieved through a gear rack transmission. Specifically, a rack 20 is provided on one side of the upper surface of the support frame 1, and a driving motor 21 is provided on one side of the mobile frame 2. The output end of the driving motor 21 is meshed with the rack 20 through a gear, and the gear is driven by the driving motor 21, thereby driving the mobile frame 2 to move horizontally along the rack 20.

[0027] The through hole 19 is perpendicular to the moving direction of the conveying roller 17, so that the ion generator 3 can slide horizontally. With the adjustment mechanism, the irradiation position can be adjusted more flexibly. The driving motor 21 drives the gear to rotate during rotation, and the gear and the rack 20 are meshed together to drive the movable frame 2 to slide.

[0028] The working principle and process of the utility model are as follows:

[0029] 1. When in use, slide the position of the ion generator 3 according to the width of the rail and the position of the conveyor roller 17, and turn the adjustment nut 14 to make the ion generator 3 accurately irradiate the rail;

[0030] 2. Connect the water inlet pipe 10 to the source of the coolant so that the coolant can be sprayed out from the nozzle 7;

[0031] 3. Rotate the threaded rod 8 so that the wiper plate 9 at one end of the threaded rod 8 rests against the rail, and the coolant remaining on the rail can be scraped off.
