Description

Technical Field

[0001] This invention relates to the field of crossbar manufacturing technology, and in particular to a crossbar surface dip coating apparatus and method. Background Technology

[0002] Crossbars installed at outdoor railway crossings need to be coated with an anti-oxidation protective paint to prevent them from rusting and oxidizing inside.

[0003] Crossbars are mostly coated with paint using a dip-coating method. Traditionally, this involves using a separate chain conveyor or roller conveyor to control the crossbar's directional movement within a paint tank for paint application. However, simply using a chain conveyor results in a large amount of paint adhering to its surface, requiring regular cleaning and impacting the conveyor's efficiency. Furthermore, roller conveyors cannot achieve continuous, automated dip-coating of crossbars, further reducing processing efficiency. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a crossbar surface dip coating apparatus and method, which can improve the dip coating processing efficiency of crossbar assemblies and ensure the continuous and stable conveying of crossbar assemblies during the dip coating process.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0006] A crossbar surface dipping coating apparatus is used to dip-coat the surface of a crossbar assembly. It includes a storage box containing a rotating device for controlling the rotation of the crossbar assembly, a loading device, and a unloading device. The unloading device is located at a predetermined position above the rotating device. A vertically arranged lifting device is provided at the lower end of the first end of the unloading device, which transports the crossbar assembly from the surface of the rotating device to the surface of the unloading device. A transfer device is installed between the rotating device and the lifting device, which transports the crossbar assembly to one side of the lifting device. The crossbar assembly includes two fixing components for fixing a plurality of crossbars. Each fixing component includes a fixing plate and a locking ring located outside the fixing plate. The rotating device includes a rotating disk that rotates about an axis, and a plurality of locking telescopic rods adapted to the locking ring are fixed to the side wall of the rotating disk.

[0007] Preferably, the feeding device includes two feeding guide rails, which are arranged at intervals. Each feeding guide rail is equipped with a feeding end, which is provided with a feeding limit protrusion. An electronic control device for controlling the deflection of the feeding end is installed on the side wall of the feeding guide rail.

[0008] Preferably, the feeding device includes two spaced-apart feeding tracks, the distance between the two feeding tracks being the same as the distance between the two feeding ends.

[0009] Preferably, the lifting device is an annular lifting structure, which includes an annular lifting belt and a drive wheel for controlling the directional rotation of the lifting belt. The outer wall of the lifting belt is provided with a limiting plate for supporting the crossbar assembly, and the surface of the limiting plate is provided with lifting limiting protrusions.

[0010] Preferably, the transfer device includes a transfer body, the lower end of which is rotatably connected to the inner wall of the storage box, and a support component for supporting the crossbar assembly is installed on the upper end of the transfer body. It also includes a drive component for controlling the transfer body to deflect around the lower end.

[0011] Preferably, the cross-section of the bearing component is annular, the upper end of the bearing component is concave, and the arc-shaped surface of the upper end of the bearing component is adapted to the outer wall of the locking ring.

[0012] Preferably, the bearing assembly includes a first bearing portion and a second bearing portion, the second bearing portion being an elastic limiting bladder filled with electrorheological fluid connected to a control power supply, and the second bearing portion being located on the side away from the lifting device.

[0013] Preferably, the driving component is a deflection telescopic rod, the base end of which is connected to the inner wall of the storage box, and the telescopic end is connected to the side wall of the transfer body.

[0014] Preferably, the side wall of the fixed plate is further provided with a plurality of sealing sleeves, the outer side of which is adapted to the end of the cross rod.

[0015] A method for dip coating a crossbar surface, using the aforementioned crossbar surface dip coating apparatus, includes the following steps: S1, a feeding device conveys the crossbar assembly to one side of a rotating device, and a locking telescopic rod on the surface of the rotating device locks and fixes the crossbar assembly; S2, the rotating device is controlled to rotate in an directional manner, and the crossbar assembly is controlled to rotate into the storage box for dip coating processing; S3, the rotating device is further controlled to rotate in an directional manner, and the dip-coated crossbar assembly is controlled to move to one side of a lifting device; S4, the crossbar assembly on the surface of the rotating device is transported to one side of the lifting device by a transfer device, and then the lifting device controls the crossbar assembly to be directionally lifted to one side of the unloading device to complete unloading.

[0016] The beneficial effects of this invention are as follows:

[0017] Compared with existing technologies, the above structural design allows the directional rotating device to perform varnishing on the crossbar assembly from a constant position, eliminating the need for specialized cleaning of its surface. The lifting device, unloading device, and transfer device enable directional transport of the crossbar assembly from the outside. These structures do not need to enter the storage box, resulting in fewer areas of residual paint on their surfaces, less frequent subsequent cleaning, and no impact on the production and transport of the crossbar assembly. This device improves the varnishing efficiency of the crossbar assembly and ensures continuous and stable transport during the varnishing process. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] To address the problems raised in the background art, see Appendix Figure 1- Appendix Figure 7 A crossbar surface dip coating apparatus is disclosed for dip coating the surface of a crossbar assembly 600. The apparatus includes a storage tank 100 for storing paint; a rotating device 200 for controlling the rotation of the crossbar assembly 600 is installed inside the storage tank 100; a feeding device 500 and a discharging device 400 are also included. The feeding device 500 conveys the crossbar assembly 600 to one side of the rotating device 200. The rotating device 200, positioned at a constant position, drives the crossbar assembly 600 to rotate. After the crossbar assembly 600 rotates to the bottom position, the paint dip coating process is completed. The crossbar assembly 600 continues to rotate in a directional direction, conveying the dip-coated crossbar assembly 600 to the surface of the discharging device 400 for unloading.

[0028] Specifically, the unloading device 400 is located at a predetermined position above the rotating device 200. A vertically arranged lifting device 300 is provided at the lower end of the first end of the unloading device 400. The lifting device 300 transports the crossbar assembly 600 from the surface of the rotating device 200 to the surface of the unloading device 400. A transfer device 700 is installed between the rotating device 200 and the lifting device 300. The transfer device 700 transports the crossbar assembly 600 to one side of the lifting device 300. Through the cooperation of the lifting device 300 and the transfer device 700, the disassembled crossbar assembly 600 can be transported to the surface of the lifting device 300 and finally to the surface of the unloading device 400, thus realizing the disassembly and transport of the crossbar assembly 600 that rotates directionally on the surface of the rotating device 200.

[0029] By setting up the lifting device 300, the crossbar assembly 600 after impregnation can be lifted in a directional manner. During this process, the crossbar assembly 600 can move along the vertical height. During this process, some of the liquid paint can drip into the storage tank 100 under the action of gravity, reducing the contamination of the paint on the subsequent structure.

[0030] The crossbar assembly 600 includes two fixing components 610 for fixing a plurality of crossbars 620. The fixing component 610 includes a fixing plate 611 and a locking ring 612 located outside the fixing plate 611. The rotating device 200 includes a rotating disk 210 that rotates about an axis. A plurality of locking telescopic rods 220 adapted to the locking rings 612 are fixed on the side wall of the rotating disk 210. The extension of the locking telescopic rods 220 is controlled, and the telescopic ends of the locking telescopic rods 220 can be locked with the locking rings 612. The crossbar assembly 600 can be fixed from both sides to ensure the stability of the crossbar assembly 600 during the paint impregnation process.

[0031] During the disassembly process, the crossbar assembly 600 is first supported from below by the transfer device 700. Then, the locking telescopic rods 220 on both sides are controlled to retract. After the locking telescopic rods 220 on both sides retract, the transfer device 700 is controlled to deflect towards the lifting device 300. The crossbar assembly 600 on the surface of the rotating device 200 is transported to the surface of the lifting device 300 for vertical transport by the transfer device 700.

[0032] In summary, through the above structural design, the directional rotating device 200 performs the dip coating process on the crossbar assembly 600 from a constant position, eliminating the need for special cleaning of its surface structure. The lifting device 300, unloading device 400, and transfer device 700 can be positioned on the outside for directional transport of the crossbar assembly 600. These structures do not need to enter the storage box 100, resulting in fewer areas of residual paint on their surfaces, lower subsequent cleaning frequency, and no impact on the production and transport of the crossbar assembly 600. This device improves the dip coating efficiency of the crossbar assembly 600 and ensures continuous and stable transport of the crossbar assembly 600 during the dip coating process.

[0033] Specifically, the feeding device 500 includes two feeding guide rails 520, which are arranged at intervals. Each feeding guide rail 520 has a feeding end 510 installed at its end. The feeding end 510 has a feeding limit protrusion at its end. An electronic control device for controlling the deflection of the feeding end 510 is installed on the side wall of the feeding guide rail 520.

[0034] During operation, the control crossbar assembly 600 rolls directionally along the two feeding guide rails 520. After rolling to the side of the feeding end 510, it is locked under the action of the feeding limit protrusion at the end of the feeding end 510. During the feeding process, the feeding end 510 is controlled to deflect towards the rotating device 200 by the electronic control device. After the locking ring 612 is aligned with the locking telescopic rod 220, the telescopic end of the locking telescopic rod 220 is extended to achieve locking feeding.

[0035] The unloading device 400 includes two spaced unloading tracks, the distance between the two unloading tracks being the same as the distance between the two loading ends 510. The structure of the unloading device 400 is similar to that of the loading device 500. The unloading tracks here can be set to be slightly inclined or have conveying rollers installed on the surface, which can directionally convey the dipped crossbar assembly 600 to realize unloading and conveying processing.

[0036] The lifting device 300 is a ring-shaped lifting structure. The lifting device 300 includes a ring-shaped lifting belt 320 and a drive wheel 310 for controlling the directional rotation of the lifting belt 320. The outer wall of the lifting belt 320 is provided with a limiting plate 321 for supporting the crossbar assembly 600. The surface of the limiting plate 321 is provided with lifting limiting protrusions. The limiting plate 321 can also tilt inward. Under the action of the lifting limiting protrusions, the stability of the crossbar assembly 600 as a whole can be further ensured during the lifting and conveying process.

[0037] The aforementioned lifting device 300 can also be a chain conveyor structure, which can control the crossbar assembly 600 to move directionally upward during the directional rotation to achieve lifting and conveying.

[0038] Specifically, the transfer device 700 includes a transfer body 720, the lower end of which is rotatably connected to the inner wall of the storage box 100. A bearing component for bearing the crossbar assembly 600 is installed on the upper end of the transfer body 720. It also includes a drive component 710 for controlling the transfer body 720 to deflect around its lower end. The drive component 710 can control the rotation of the axis of the lower end of the transfer body 720. Controlling the transfer body 720 to rotate in the direction of the rotating device 200 can complete the bearing gripping of the crossbar assembly 600. Controlling the transfer body 720 to deflect in the direction of the lifting device 300 can transport the crossbar assembly 600 on one side of the rotating device 200 to the side of the lifting device 300, thus completing the transfer and conveying of the crossbar assembly 600.

[0039] The drive assembly 710, the transfer body 720, and the load-bearing assembly are also set in two groups, which can carry and transfer the crossbar assembly 600 from both sides. At the same time, the width of the load-bearing assembly is staggered from the limit plate 321 to avoid interference with the crossbar assembly 600 during the transport process.

[0040] The preferred bearing component has an annular cross-section, with the upper end of the bearing component being concave, and the arc-shaped surface of the upper end of the bearing component being adapted to the outer wall of the locking ring 612.

[0041] Through the above structural design, the shape of the bearing component can be adapted to the locking ring 612, further ensuring the stability of the locking ring 612 during the deflection and transportation process.

[0042] Furthermore, the support assembly includes a first support portion 722 and a second support portion 723. The second support portion 723 is an elastic limiting bladder filled with electrorheological fluid, which is connected to a control power supply. The second support portion 723 is located on the side away from the lifting device 300.

[0043] During the process of controlling the bearing assembly to deflect in the direction of the rotating device 200, the electrochemical fluid in the second bearing part 723 is controlled to be in a non-conductive liquid state. During this process, the second bearing part 723 can pass through the locking ring 612 and enter the outside of the locking ring 612. With the above structure, there is no need to adjust the deflection angle of the rotating device 200, which reduces the control difficulty.

[0044] During the process of controlling the bearing component to deflect in the direction of the lifting device 300, the electrorheological fluid in the second bearing part 723 is controlled to become a conductive solid. During this process, the solid second bearing part 723 can support and limit the crossbar assembly 600 from the outside, ensuring the stability of the overall movement of the crossbar assembly 600.

[0045] It should be noted that the second bearing portion 723 here is elastic, and after moving to the outside of the locking ring 612, it can return to its initial state under the action of elasticity, that is, attached... Figure 7 The state shown in the image.

[0046] Specifically, the drive assembly 710 is a deflection telescopic rod. The base end of the deflection telescopic rod is connected to the inner wall of the storage box 100, and the telescopic end is connected to the side wall of the transfer body 720. By setting the above structure, the drive assembly 710 and the transfer body 720 can use the lever effect to ensure the stability of the transfer body 720 driving the cross rod assembly 600 to move, thus ensuring the accuracy and stability of the overall transfer and transportation of the cross rod assembly 600.

[0047] Several sealing sleeves 613 are also provided on the side wall of the fixed plate 611. The outer side of the sealing sleeve 613 is adapted to the end of the cross rod 620. By setting the sealing sleeve 613, the cross rod 620 can be sealed and limited from the outside, preventing paint from entering the port of the cross rod 620 from both sides, reducing the difficulty of later cleaning. At the same time, the sealing sleeve 613 is equipped with a locking structure, which can lock and limit the cross rod 620, ensuring that the cross rod 620 and the fixed component 610 are in a stable state during the paint impregnation process, and preventing accidents. The locking structure mentioned above can be a locking bolt.

[0048] A method for dip coating the surface of a crossbar, using the aforementioned dip coating apparatus for the crossbar surface, includes the following steps:

[0049] S1. The crossbar assembly 600 is conveyed to one side of the rotating device 200 by the feeding device 500. The crossbar assembly 600 is locked and fixed by the locking telescopic rod 220 on the surface of the rotating device 200. The locking telescopic rod 220 is controlled to extend, and the telescopic end of the locking telescopic rod 220 can be adapted to the locking ring 612 to ensure the stability of the locking and fixing of the crossbar assembly 600.

[0050] S2. Control the rotation of the rotating device 200 to rotate in a specific direction, and control the crossbar assembly 600 to rotate into the storage box 100 for dip coating processing; see appendix for details. Figure 3 The rotating device 200 here can rotate counterclockwise, and the crossbar assembly 600 moves from a higher position downwards to complete the impregnation process.

[0051] S3. Continue to control the rotation of the rotating device 200 to rotate in a specific direction, and control the crossbar assembly 600 after dip coating to move to one side of the lifting device 300; the crossbar assembly 600 is transferred and transported to one side of the lifting device 300 through the transfer device 700, completing the transfer and transport between the rotating device 200 and the lifting device 300.

[0052] S4. The crossbar assembly 600 on the surface of the rotating device 200 is transported to one side of the lifting device 300 by the transfer device 700. Then, the lifting device 300 controls the crossbar assembly 600 to be oriented and lifted to one side of the unloading device 400 to complete the unloading. During this process, excess paint on the surface of the crossbar assembly 600 can drip into the storage box 100, avoiding excessive paint dripping into the subsequent structure and causing conveying obstacles. At the same time, excess paint can be recycled to avoid resource waste.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
