Description

Technical Field

[0001] This utility model relates to the field of metal material processing technology, and in particular to a device for surface passivation treatment of railway embedded parts. Background Technology

[0002] Passivation treatment of railway embedded parts can enhance their corrosion resistance, form a protective barrier to prevent localized corrosion, and increase the service life of the embedded parts.

[0003] For passivation treatment of embedded parts, a strong oxidant is usually sprayed onto their surface. For example, the embedded part is hung up by a hook and placed in the air, and then a strong oxidant is sprayed onto the surface of the embedded part by a spray head. However, there is a part of mutual contact and coverage between the hook and the embedded part, which causes the spraying of the strong oxidant to be incomplete, and the surface of the embedded part is not passivated. Utility Model Content

[0004] The purpose of this invention is to propose a surface passivation treatment device for railway embedded parts, which solves the problem that strong oxidants cannot come into contact with some parts of the embedded parts during spray passivation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The surface passivation treatment device for railway embedded parts includes four contact wheels, which are located in the four directions of up, down, left, and right, respectively, to limit the contact of the embedded steel plate of the embedded part on the four sides. A disc with a diameter larger than the contact wheel is set on both sides of the contact wheel to limit the contact of the embedded steel plate with the contact wheel. Any one of the contact wheels can be driven by an electric drive device, and the remaining three contact wheels can slide in their respective positions.

[0007] Preferably, a rubber ring is fixedly sleeved on the outer edge of the contact wheel. The friction coefficient of the rubber ring is greater than that of the outer edge of the contact wheel. The outer diameter of the rubber ring is smaller than the diameter of the disc. The disc consists of a first disc located on one side of the contact wheel and a second disc located on the other side of the contact wheel.

[0008] Preferably, the processing device further includes a cross, having extensions in four directions (up, down, left, and right), with grooves formed in any three of the extensions, and a contact wheel on the extension with the groove is elastically connected to its corresponding groove.

[0009] Preferably, the extension also has a limiting groove, and the sliding groove and the limiting groove are connected. The limiting groove is slidably connected to a sliding plate, and the sliding plate is fixedly connected to a fixed shaft. The fixed shaft passes through the first disc, the contact wheel and the second disc in sequence. The other end of the fixed shaft is coaxially fixedly connected to a locking disc. The shortest straight distance between the locking disc and the cross is the sum of the thicknesses of the first disc, the contact wheel and the second disc. The first disc, the contact wheel and the second disc can rotate relative to the fixed shaft.

[0010] Preferably, a fixing rod is fixedly connected in the limiting groove, the fixing rod passes through the slide plate, and a spring is sleeved on the outer wall of the fixing rod, with the two ends of the spring connected to the limiting groove and the slide plate respectively.

[0011] Preferably, the electric drive device includes a sealing box, which is fixedly connected to the cross, and a motor is installed inside the sealing box. The output end of the motor extends out of the sealing box, passes through the cross, and is fixedly connected to one of the first discs on the same axis.

[0012] Preferably, the processing device further includes a buckle body in the shape of an annular ring, with three wires bound to the outer edge of the buckle body. The other ends of the three wires extend into three extensions with limiting grooves and are bonded to the slide plate. When the buckle body is pulled away from the cross, the slide plate moves in the direction away from the center of the cross.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses four contact wheels to clamp the four side walls of the embedded steel plate to complete the clamping. Then, one of the rotatable contact wheels rotates to drive the clamped embedded steel plate to rotate, so that the entire outer surface of the embedded steel plate is sprayed and covered with a strong oxidant, solving the problem that the strong oxidant cannot reach some parts of the embedded part during spray passivation.

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

[0023] Reference Appendix Figure 1 -Appendix Figure 5 Example 1: A passivation treatment device for the surface of railway embedded parts includes four contact wheels 1, which are located in the four directions of up, down, left, and right, respectively, to limit the contact of the embedded steel plate of the embedded part on the four sides. A disc with a diameter larger than that of the contact wheel 1 is set on both sides of the contact wheel 1 to limit the contact of the embedded steel plate with the contact wheel 1. In this example, any one of the contact wheels 1 is driven by an electric drive device, and the remaining three contact wheels 1 can slide in their respective positions. In this example, the lower contact wheel 1 is selected as the fixed position, and the remaining three contact wheels 1 can slide.

[0024] A rubber ring 2 is fixedly sleeved on the outer edge of the contact wheel 1. The friction coefficient of the rubber ring 2 is greater than that of the outer edge of the contact wheel 1. When the contact wheel 1 rotates, it can better drive the rotation of the clamped embedded steel plate, so that the outer surface of the embedded steel plate is completely sprayed and covered by a strong oxidant. The outer diameter of the rubber ring 2 is smaller than the diameter of the disc body. The disc body consists of a first disc 3 located on one side of the contact wheel 1 and a second disc 4 located on the other side of the contact wheel 1. The first disc 3 and the second disc 4 are set to prevent the clamped embedded steel plate from detaching from the four contact wheels 1, and play a limiting role.

[0025] The processing device also includes a cross 5 with extensions in four directions: up, down, left, and right. Slots 6 are provided in any three of the extensions, and a contact wheel 1 on the extension with the slot 6 is elastically connected to its corresponding slot 6.

[0026] The extension also has a limiting groove 7, and the sliding groove 6 is connected to the limiting groove 7. The depth of the limiting groove 7 is half the depth of the sliding groove 6, which is used to prevent the sliding plate 8, which is slidably connected to the limiting groove 7, from falling off the sliding groove 6. The limiting groove 7 is slidably connected to the sliding plate 8, and the sliding plate 8 is fixedly connected to the fixed shaft 9. The fixed shaft 9 passes through the first disc 3, the contact wheel 1, and the second disc 4 in sequence. The other end of the fixed shaft 9 is coaxially fixedly connected to the locking disc 10. The shortest straight distance between the locking disc 10 and the cross 5 is the sum of the thicknesses of the first disc 3, the contact wheel 1, and the second disc 4. The first disc 3, the contact wheel 1, and the second disc 4 can rotate relative to the fixed shaft 9.

[0027] A fixing rod 11 is fixedly connected in the limiting groove 7. The fixing rod 11 passes through the slide plate 8. A spring 12 is sleeved on the outer wall of the fixing rod 11. The two ends of the spring 12 are connected to the limiting groove 7 and the slide plate 8 respectively.

[0028] The electric drive device includes a housing 13, which protects the motor 14 from being sprayed with strong oxidant. The housing 13 is fixedly connected to the cross 5. The motor 14 is installed inside the housing 13. The output end of the motor 14 extends out of the housing 13 and passes through the cross 5 to be fixedly connected coaxially to one of the first discs 3.

[0029] Working principle:

[0030] Select the embedded steel plate that needs to be passivated, pull the three sliding contact wheels 1 to slide to a position away from the center of the cross 5, thereby expanding the clamping range. After expanding, place the embedded steel plate and cancel the pulling of the contact wheels 1. Under the action of the spring 12, the three contact wheels 1 move towards the center of the cross 5 until they clamp the three sides of the embedded steel plate, thus completing the clamping.

[0031] Reference Appendix Figure 6 In the second embodiment, based on the first embodiment, three contact wheels 1 can be pulled simultaneously. Specifically, the processing device also includes a buckle body 15, which is in the shape of a ring. Three wires 16 are bound to the outer edge of the buckle body 15. The other ends of the three wires 16 extend into three extensions with limiting grooves 7 and are bonded to the slide plate 8. When the buckle body 15 is pulled away from the cross 5, the slide plate 8 moves in the direction away from the center of the cross 5.

[0032] This technical solution facilitates the synchronous adjustment of the three contact wheels 1, enabling faster and more convenient clamping of the embedded steel plate and providing convenience for subsequent strong oxidant spraying.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
