Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail spring processing technology, and in particular to a rail spring coating processing device. Background Technology
[0002] As a key load-bearing component in railway systems, rail springs are exposed to corrosive environments such as humidity and salt spray for extended periods. The quality of their surface anti-corrosion coating directly affects spring life and train operation safety. During the coating process, the anti-corrosion material is evenly applied to the spring surface through immersion, and excess coating is removed by high-speed spin drying.
[0003] Currently, in the coating process of rail springs, the rail springs are directly placed into a soaking basket, and the basket is rotated in the soaking tank by a rotating mechanism to complete the coating. After coating, the basket is rotated again by the rotating mechanism to spin dry. This process ensures that the rail springs are in full contact with the coating liquid through the rotation of the basket, and uses centrifugal force to remove excess coating liquid, thus achieving an integrated operation of coating and spin drying. However, the above-mentioned technology has the following problems: because the rail springs have notches, during the rotation process, the scattered rail springs are very easy to hook and entangle with each other, forming clumps. This entanglement not only affects the appearance quality of the coating and causes uneven coating, but also requires manual untangling of the tangled rail springs in the next process, which increases labor costs and is also prone to damaging the coating of the rail springs. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model provides a rail spring coating processing device, which solves the technical problem that rail springs are prone to hooking and tangling together during the coating processing of rail springs in the prior art.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A rail spring coating processing device is used for coating the surface of a rail spring and then drying it. The rail spring includes: a square ring body with a notch, and a recessed portion on one side opposite the notch, the recessed portion extending to the notch on both sides to form a pair of square rings. A barrel with an opening at the top, the barrel having a cavity inside; A soaking basket frame is rotatably disposed within a cavity. The soaking basket frame has a plurality of liquid holes. The soaking basket frame includes: a cylindrical body with an open top, a plurality of columns disposed within the cylindrical body, and the plurality of columns being installed at intervals on the bottom wall of the soaking basket frame. The spacing between adjacent pairs of columns corresponds to a pair of square rings. A rotating mechanism for driving the soaking basket frame to rotate.
[0006] Based on the above structure, the principle of the rail spring coating processing device is as follows: When processing the rail spring coating, firstly, a square ring is placed in the soaking basket, with a pair of square rings respectively fitted onto a pair of adjacent columns; then, coating liquid is injected into the cavity until it submerges the uppermost square ring, and the coating liquid enters the soaking basket through the liquid hole; subsequently, the rotating mechanism is started, driving the soaking basket to rotate in the cavity at a preset speed, so that the square rings in the soaking basket are in full contact with the coating liquid. The pair of square rings respectively fitted onto a pair of adjacent columns ensures that the square rings remain stable during the rotation of the soaking basket, preventing them from tilting. The misalignment caused entanglement. After the coating of the square ring was completed, the rotating mechanism was turned off, the coating liquid in the cavity was drained, and then the rotating mechanism was restarted to drive the soaking basket to rotate in the cavity at a preset spin-drying speed. The excess coating liquid was thrown out through the liquid hole under the action of centrifugal force and flowed back into the cavity, so that the coating thickness on the surface of the square ring was uniform. Similarly, during the spin-drying process, the adjacent pair of columns always kept the square ring on the pair of columns to prevent entanglement. After the spin-drying was completed, the rotating mechanism was turned off, and after the soaking basket stopped rotating, the soaking basket was removed from the cavity, and then the square ring was removed from the columns, completing the entire coating process.
[0007] Furthermore, the rail spring coating processing device of this application further includes a lifting mechanism, which includes a platform and a lifting drive device. The barrel is disposed on the platform, and the lifting drive device is used to lift the platform vertically. As a preferred embodiment of this application, the rail spring coating processing device uses the lifting drive device to drive the platform to adjust the height of the soaking basket frame in the cavity, making it easier for operators to smoothly place the rail spring onto the column in the soaking basket frame without having to reach into the coating liquid, thus improving operational convenience and safety. Moreover, in the spin-drying process, the relative position of the barrel and the soaking basket frame can be adjusted so that the soaking basket frame is detached from the coating liquid, allowing excess coating liquid on the surface of the rail spring to drip back into the cavity before the column is started for spin-drying, reducing the amount of coating liquid splashing during spin-drying.
[0008] Furthermore, in a rail spring coating processing device of this application, a stop is provided on the platform, and the stop is arranged along the circumference of the barrel. As a preferred embodiment of this application, the stop is used to laterally limit the barrel, reducing the swaying or displacement of the barrel during the operation of the platform lifting or rotating mechanism, ensuring the relative position stability of the barrel with the soaking basket and the column, so as to ensure the safe operation of the device.
[0009] Furthermore, in the rail spring coating processing apparatus of this application, the liquid holes on the side wall of the soaking basket are evenly spaced along the axial and circumferential directions of the soaking basket. As a preferred embodiment of this application, the liquid holes on the side wall of the soaking basket are evenly distributed along the axial and circumferential directions of the soaking basket, allowing the coating liquid to evenly penetrate from the cavity into the soaking basket through the liquid holes on the side wall during soaking. This ensures that rail springs at different heights receive sufficient and uniform contact and coating. During spin-drying, the evenly distributed liquid holes on the side wall provide a uniform discharge channel for the coating liquid, preventing local accumulation or excessive sparseness that could obstruct drainage. This allows the coating liquid to be evenly returned to the cavity, ensuring a uniform thickness of the coating on the rail spring surface.
[0010] Furthermore, in the rail spring coating processing apparatus of this application, the liquid holes on the bottom wall of the soaking basket are respectively arranged at intervals along the radial and circumferential directions of the soaking basket. As a preferred embodiment of this application, during the spin-drying process, the liquid holes on the bottom wall of the soaking basket are used to drain the coating liquid from the entire soaking basket, preventing local liquid accumulation from affecting the uniformity of the coating; during the process of immersing the soaking basket into the coating liquid, the liquid holes on the bottom wall of the soaking basket facilitate the smooth discharge of internal air, avoiding the formation of air chambers due to air retention in the soaking basket, which would hinder the coating liquid from entering the interior of the soaking basket, and ensuring that the coating liquid can cover all rail springs.
[0011] Furthermore, in a rail spring coating processing apparatus of this application, an extension is provided on the outer wall of the cylinder, the extension extending radially along the cylinder. The rotating mechanism includes a rotating drive device and a set of clamping components. The set of clamping components is evenly spaced along the circumference of the soaking basket frame. The clamping components are radially movable and adjustable along the soaking basket frame. Each clamping component has a clamping groove corresponding to the extension, the clamping groove being used to accommodate the extension. The rotating drive device is used to drive the set of clamping components to rotate around the axis of the cylinder. As a preferred embodiment of this application, in a rail spring coating processing apparatus of this application, after the clamping groove accommodates the extension, the rotating drive device drives the set of clamping components to rotate around the axis of the cylinder, thereby driving the entire soaking basket frame to rotate synchronously. The set of clamping components is radially movable and adjustable along the soaking basket frame, pushing the clamping groove to engage the extension, forming a rigid connection through interference fit. The design of the set of clamping components being radially movable and adjustable along the soaking basket frame can adapt to soaking basket frames of different sizes. By adjusting the radial position of the set of clamping components, the clamping groove can be matched with extensions of different specifications, improving the versatility of the apparatus.
[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: This utility model provides a rail spring coating processing device. By using spaced columns to position and fix a square ring, it ensures the stability and anti-winding ability of the ring during the dipping and drying process. Combined with a lifting mechanism, it facilitates operation and improves safety. With the help of a soaking basket frame with evenly distributed liquid holes, it achieves uniform dipping and drying of the coating and effectively reduces the amount of coating liquid splashing.

[0015] like Figure 1 , 2 As shown in Figures 3 and 4, a rail spring coating processing device is used for coating the surface of a rail spring and drying it after coating. The rail spring includes: a square ring body 1, the square ring body 1 having a notch 10, and a recess 11 on one side opposite to the notch 10, the recess 11 extending to the notch 10 on both sides to form a pair of square rings, including: A barrel body 2 with an opening at the top, wherein a cavity 20 is provided inside the barrel body 2; A soaking basket frame 3 is rotatably disposed within a cavity 20. The soaking basket frame 3 is provided with a plurality of liquid holes 30. The soaking basket frame 3 includes: a cylindrical body 31 with an open upper end, and a plurality of columns 4 are provided inside the cylindrical body 31. The plurality of columns 4 are spaced apart and installed on the bottom wall of the soaking basket frame 3. The spacing between an adjacent pair of columns 4 corresponds to a pair of square rings. Rotating mechanism 5, which is used to drive the soaking basket frame 3 to rotate.
[0016] Based on the above structure, the principle of the rail spring coating processing device is as follows: When it is necessary to process the rail spring coating, firstly, a square ring 1 is placed in the soaking basket 3, and a pair of square rings are respectively fitted onto a pair of adjacent columns 4; then, coating liquid is injected into the cavity 20 until it submerges the uppermost square ring 1, and the coating liquid enters the soaking basket 3 through the liquid hole 30; subsequently, the rotating mechanism 5 is started, driving the soaking basket 3 to rotate in the cavity 20 at a preset speed, so that the square ring 1 in the soaking basket 3 is in full contact with the coating liquid, and the pair of square rings are respectively fitted onto a pair of adjacent columns 4, ensuring that the square ring 1 remains stable during the rotation of the soaking basket 3, and preventing it from tilting or misaligning. During the spin-drying process, the coating of the square ring 1 is applied. Then, the rotating mechanism 5 is turned off, the coating liquid in the cavity 20 is drained, and the rotating mechanism 5 is turned on again to drive the soaking basket 3 to rotate in the cavity 20 at a preset spin-drying speed. The excess coating liquid is thrown out through the liquid hole 30 under the action of centrifugal force and flows back into the cavity 20, so that the coating thickness on the surface of the square ring 1 is uniform. Similarly, during the spin-drying process, the adjacent pair of columns 4 always limit the square ring 1 on the pair of columns 4 to prevent it from entangled. After the spin-drying is completed, the rotating mechanism 5 is turned off, and after the soaking basket 3 stops rotating, the soaking basket 3 is removed from the cavity 20, and the square ring 1 is removed from the column 4 to complete the entire coating process.
[0017] This embodiment also includes a lifting mechanism 6, which comprises a platform 61 and a lifting drive device. The barrel 2 is mounted on the platform 61, and the lifting drive device is used to lift the platform 61 vertically. The lifting drive device drives the platform 61 to adjust the height of the soaking basket 3 within the cavity 20, facilitating the operator to smoothly place the rail spring onto the column 4 within the soaking basket 3 without needing to reach into the coating liquid, thus improving operational convenience and safety. Furthermore, during the spin-drying process, the relative position of the barrel 2 and the soaking basket 3 can be adjusted to detach the soaking basket 3 from the coating liquid, allowing excess coating liquid on the surface of the rail spring to drip back into the cavity 20 before the column 4 is activated for spin-drying, reducing the amount of coating liquid splashing during spin-drying. The lifting drive device is a hydraulic drive device (not shown).
[0018] In this embodiment, the platform 61 is provided with a stop 611, which is arranged along the circumference of the barrel 2. The stop 611 is used to laterally limit the barrel 2, reducing the shaking or displacement of the barrel 2 during the operation of the lifting or rotating mechanism 5 of the platform 61, and ensuring the relative position stability of the barrel 2 with the soaking basket frame 3 and the column 4, so as to ensure the safe operation of the device.
[0019] In this embodiment, the liquid holes 30 are evenly spaced along the axial and circumferential directions of the soaking basket 3 on its side wall. The even distribution of the liquid holes 30 along the axial and circumferential directions of the soaking basket 3 allows the coating liquid to evenly penetrate from the cavity 20 into the soaking basket 3 through the liquid holes 30 on its side wall during soaking, ensuring that rail springs at different heights receive sufficient and uniform contact and coating. During spin-drying, the evenly distributed liquid holes 30 on the side wall provide a uniform discharge channel for the coating liquid, preventing local accumulation or excessive sparseness that could obstruct drainage. This allows the coating liquid to be evenly returned to the cavity 20, ensuring a uniform thickness of coating on the rail spring surface.
[0020] In this embodiment, the liquid holes 30 are arranged at intervals along the radial and circumferential directions on the bottom wall of the soaking basket 3. During spin-drying, the liquid holes 30 on the bottom wall of the soaking basket 3 are used to drain the coating liquid from the entire soaking basket 3, preventing local liquid accumulation from affecting the uniformity of the coating. During the process of immersing the soaking basket 3 into the coating liquid, the liquid holes 30 on the bottom wall of the soaking basket 3 facilitate the smooth discharge of internal air, avoiding the formation of air chambers due to air retention in the soaking basket 3, which would hinder the coating liquid from entering the interior of the soaking basket 3, and ensuring that the coating liquid can cover all rail springs.
[0021] In this embodiment, an extension 32 is provided on the outer side wall of the cylinder 31. The extension 32 extends radially along the cylinder 31. The rotating mechanism 5 includes a rotating drive device and a set of clamping components 51. The set of clamping components 51 are evenly spaced along the circumference of the soaking basket frame 3. The clamping components 51 are movably adjustable along the radial direction of the soaking basket frame 3. The clamping components 51 are provided with clamping grooves 510 corresponding to the extension 32. The clamping grooves 510 are used to accommodate the extension 32. The rotating drive device is used to drive the set of clamping components 51 to rotate around the axis of the cylinder 31. After the clamping groove 510 accommodates the extension 32, the rotation drive device drives a set of clamping components 51 to rotate around the axis of the cylinder 31, thereby driving the entire soaking basket 3 to rotate synchronously. The set of clamping components 51 is adjustable radially along the soaking basket 3, pushing the clamping groove 510 to engage with the extension 32, forming a rigid connection through an interference fit. The design of the set of clamping components 51 being adjustable radially along the soaking basket 3 can accommodate soaking baskets 3 of different sizes. By adjusting the radial position of the set of clamping components 51, the clamping groove 510 can be matched with extensions 32 of different specifications, improving the versatility of the device. The number of clamping components 51 is 6. The radial movement mechanism of the set of clamping components 51 (not shown) can be a hydraulic cylinder; the rotation drive device is an electric motor (not shown).
