Technical Field

[0001] The utility model relates to the technical field of metal electrochemistry processing, in particular to a plasma plating device for rust prevention of railway track surfaces. Background Technique

[0002] Railway tracks are made of steel. They can bear greater weight than other materials and are steel products formed by cold rolling. When using cold-rolled materials, plating is required. Plating technology can significantly improve the service life and reliability of components, improve the utilization rate of equipment, reduce the production and reserve of accessories, and particularly plays an important role in increasing production and saving, repairing and reusing waste, and saving energy, thus having broad prospects.

[0003] Publication No. CN211997828U discloses a plating device for railway rail transit that is convenient for assembly. When this patent conducts continuous plating process on railway tracks, the whole process is automated, greatly reducing manual operation intervention. The processes of putting in, taking out, and conveying are completed coherently, greatly improving the processing efficiency. However, the following problems still exist in the actual use of this patent:

[0004] The railway track is limited by a fixed clamp block, and then the rotation of the fixed clamp block can drive the railway track to rotate, so that the railway track can be put into the plating tank. However, in actual use, when the railway track is limited by the fixed clamp block, the railway track cannot be guaranteed to be accurately aligned with the fixed clamp block during transportation. When the fixed clamp block drives the railway track to rotate, there will be a certain space inside the fixed clamp block and the railway track, and the railway track cannot be well positioned.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this plasma coating equipment for rust prevention of railway rail surfaces, positioning components are provided at one end of each of the first hydraulic cylinder and the second hydraulic cylinder, so that when the railway rail is rotated, the railway rail can be reliably positioned, preventing the railway rail from shifting or falling, improving the stability of the rotation of the railway rail, facilitating subsequent coating of the railway rail, and enhancing the practicability. The specific content is as follows:

[0020] 1. Positioning components are provided at one end of each of the first hydraulic cylinder and the second hydraulic cylinder. The railway rail is conveyed by a conveyor belt. When coating the railway rail, the first hydraulic cylinder and the second hydraulic cylinder are started, so that the two positioning components move above and below the railway rail, making the top and bottom of the middle part of the railway rail contact with the two movable plates respectively. By driving the mounting plate to move through the first hydraulic cylinder and the second hydraulic cylinder, since the movable plate abuts against the railway rail, the movement of the mounting plate can drive the movable rod to slide on the mounting plate and stretch the telescopic spring. After the mounting plate moves, it can drive the fixed rod to move. After the fixed rod moves, it can push the connecting rod to rotate. After the connecting rod rotates, it can push the sliding rod to slide on the fixed frame, making the two positioning plates approach each other, clamping the railway rail, limiting the railway rail, and then making the railway rail leave the conveyor belt. The driving motor is started to drive the worm to rotate, and the turntable rotates through the meshing of the worm and the worm wheel, thereby driving the positioned railway rail to rotate, making the railway rail rotate between the two conveyor belts. Through the first hydraulic cylinder and the second hydraulic cylinder, the railway rail enters the coating box to perform the coating process, injecting a certain dose and energy of ions onto the surface of the railway rail to form a nano-amorphous structure, changing the chemical composition, physical structure, and phase state of the material surface layer, thereby changing the mechanical properties, chemical properties, and physical properties of the material, enhancing the wear resistance, corrosion resistance, and hardness of the railway rail. After coating, the railway rail is lifted by the first hydraulic cylinder and the second hydraulic cylinder, making the railway rail rotate and return to the conveyor belt again. Through the positioning components, when the railway rail is rotated, the railway rail can be reliably positioned, preventing the railway rail from shifting or falling, improving the stability of the rotation of the railway rail, facilitating subsequent coating of the railway rail, and enhancing the practicability;

[0021] 2. During the rotation of the railway track, the rotating plate can drive the interior of the coating box to rotate. During the rotation of the rotating plate, the limiting rod can slide inside the limiting groove. Through the rotation of the rotating plate, the limiting rod can be pushed to move on the mounting frame and stretch the return spring. After the rotating plate rotates to make the railway track rotate between the two conveyor belts, the limiting rod can align with another set of limiting grooves on the rotating plate, enabling the limiting of the rotating plate. The rotating plate can be limited by the limiting rod, so that the rotating plate will not move easily. Furthermore, when the railway track is not being coated, the rotating plate will not rotate easily, thus avoiding the rotation of the second hydraulic cylinder and preventing the subsequent positioning work of the railway track from being affected.

[0029] Please refer to Figures 1-5, the present utility model provides a technical solution: a plasma plating device for preventing rust on railway rail surfaces, including a plating tank 1 and a support frame 101. A conveyor belt 106 is symmetrically arranged between the plating tank 1 and the support frame 101. It further includes: a turntable 102 is rotatably connected to the bottom of the support frame 101, and a rotating plate 104 is rotatably connected to the inner bottom end of the plating tank 1. Moreover, a first hydraulic cylinder 103 is fixedly installed at the bottom of the turntable 102, and a second hydraulic cylinder 105 is fixedly installed at the top of the rotating plate 104. And positioning components 2 are arranged at the ends of the first hydraulic cylinder 103 and the second hydraulic cylinder 105 that are close to each other. Among them, the positioning component 2 includes a mounting plate 201 fixedly installed at one end of the first hydraulic cylinder 103 and the second hydraulic cylinder 105. And movable rods 202 are symmetrically and slidably connected inside the mounting plate 201. And a movable plate 203 is fixedly installed at one end of the two movable rods 202. And a telescopic spring 204 is sleeved on the outer side of each of the two movable rods 202. Among them, one end of the telescopic spring 204 is fixedly connected to the mounting plate 201, and the other end of the telescopic spring 204 is fixedly connected to the movable rod 202. And fixing frames 205 are symmetrically installed on the side of the movable plate 203 away from the mounting plate 201. And sliding rods 206 are slidably connected inside each of the two fixing frames 205. Through the positioning component 2, when the railway rail is rotated, the railway rail can be reliably positioned, avoiding the displacement of the railway rail and the falling of the railway rail, improving the stability of the rotation of the railway rail, facilitating the subsequent plating of the railway rail, and improving the practicability.

[0030] On the side where the two sliding rods 206 are close to each other, a positioning plate 207 is fixedly installed. On the outer side of the two sliding rods 206, a tension spring 208 is sleeved. One end of the tension spring 208 is fixedly connected to the positioning plate 207, and the other end of the tension spring 208 is fixedly connected to the fixed frame 205, so that the positioning plate 207 can automatically reset after moving. On one side of the two movable rods 202, the mounting plate 201 is fixedly installed with fixing rods 209. At the ends of the two fixing rods 209 away from the mounting plate 201, connecting rods 210 are hinged. The ends of the two connecting rods 210 away from the fixing rods 209 are respectively hinged to the two sliding rods 206, so that the movement of the fixing rods 209 can push the sliding rods 206 to move. On the outer side of the turntable 102, a worm gear 108 is fixedly installed. At the bottom of the support frame 101 on one side of the turntable 102, support blocks 107 are symmetrically installed. Between the two support blocks 107, a worm 109 is rotatably connected. The worm 109 is meshed with the worm gear 108. On one side of one support block 107, a driving motor 110 is fixedly installed. The output end of the driving motor 110 passes through the support block 107 and is fixedly connected to the worm 109, which can realize the rotation of the railway track. Inside the coating box 1, on both sides of the rotating plate 104, mounting frames 112 are symmetrically installed. Inside the two mounting frames 112, limiting rods 113 are slidably connected. On the outer side of the rotating plate 104, a number of limiting grooves 111 are opened. The limiting rods 113 are adapted to the limiting grooves 111, which can limit the rotating plate 104. On the outer side of the two limiting rods 113, a return spring 114 is sleeved. One end of the return spring 114 is fixedly connected to the mounting frame 112, and the other end of the return spring 114 is fixedly connected to the limiting rod 113, so that the limiting rod 113 can automatically reset after moving. On the side where the two positioning plates 207 are close to each other, a number of protrusions are fixedly installed, improving the positioning effect of the positioning plate 207.

[0031] Working principle: Before using this plasma coating equipment for rust prevention of railway track surfaces, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown in the figure, positioning components 2 are provided at one end of the first hydraulic cylinder 103 and the second hydraulic cylinder 105. The railway tracks are conveyed by the conveyor belt 106. When coating the railway tracks, the first hydraulic cylinder 103 and the second hydraulic cylinder 105 are started, so that the two positioning components 2 move above and below the railway tracks, and the top and bottom of the middle part of the railway tracks are respectively in contact with the two movable plates 203. By driving the mounting plate 201 with the first hydraulic cylinder 103 and the second hydraulic cylinder 105, since the movable plate 203 abuts against the railway track, the movement of the mounting plate 201 can drive the movable rod 202 to slide on the mounting plate 201 and stretch the telescopic spring 204. After the mounting plate 201 moves, it can drive the fixed rod 209 to move. After the fixed rod 209 moves, it can push the connecting rod 210 to rotate. After the connecting rod 210 rotates, it can push the sliding rod 206 to slide on the fixed frame 205, so that the two positioning plates 207 approach each other, clamping the railway track, limiting the railway track. Then, the railway track leaves the conveyor belt 106. The driving motor 110 is started to drive the worm 109 to rotate. By meshing with the worm gear 108, the turntable 102 rotates, and then the positioned railway track can be driven to rotate, so that the railway track rotates between the two conveyor belts 106. Through the first hydraulic cylinder 103 and the second hydraulic cylinder 105, the railway track enters the coating tank 1, and the coating process is carried out on the railway track. A certain dose and energy of ions are injected onto the surface of the railway track to form a nano-amorphous structure, changing the chemical composition, physical structure and phase state of the material surface layer, thereby changing the mechanical properties, chemical properties and physical properties of the material, improving the wear resistance, corrosion resistance and hardness of the railway track. After coating, the railway track is lifted by the first hydraulic cylinder 103 and the second hydraulic cylinder 105, so that the railway track rotates and returns to the conveyor belt 106 again. Through the positioning component 2, when the railway track rotates, the railway track can be reliably positioned, preventing the railway track from shifting and falling, improving the stability of the railway track rotation, facilitating the subsequent coating of the railway track, and improving the practicability;

[0032] During the rotation of the railway track, the rotating plate 104 can drive the inside of the coating tank 1 to rotate. During the rotation of the rotating plate 104, the limiting rod 113 can slide inside the limiting groove 111. By the rotation of the rotating plate 104, the limiting rod 113 can be pushed to move on the mounting frame 112 and stretch the return spring 114. After the rotating plate 104 rotates and the railway track rotates between the two conveyor belts 106, the limiting rod 113 can be aligned with another set of limiting grooves 111 on the rotating plate 104, so that the rotating plate 104 can be limited. The rotating plate 104 can be limited by the limiting rod 113, so that the rotating plate 104 will not move easily. Then, when the railway track is not being coated, the rotating plate 104 will not rotate easily, thus preventing the second hydraulic cylinder 105 from rotating and avoiding affecting the subsequent positioning work of the railway track.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
