Description

Technical Field

[0001] This utility model relates to the field of box body spraying technology, and in particular to a hanging device for box body spraying. Background Technology

[0002] Environmental testing equipment enclosures all require spray coating, a crucial process for improving product protection and appearance. Currently, traditional enclosure spraying methods primarily involve placing and securing the enclosures on trolleys, followed by manual or semi-automatic spraying equipment for coating. However, this method requires numerous trolleys and considerable space, and enclosures placed on trolleys result in uneven coating, low efficiency, and reduced production cycles. To address these issues, a conveyor line is typically used to hoist the enclosures to the spraying area, with the enclosures connected to the conveyor line via hangers. Existing hangers for enclosures often employ hook mechanisms, such as those disclosed in patent (CN214637562U) for liquefied gas tank spraying production lines. However, using these hook mechanisms leads to poor stability during enclosure hoisting; furthermore, the existing hangers are positioned directly above the enclosures, interfering with the spraying process.

[0003] In summary, the existing hoisting fixtures for lifting boxes result in poor stability of the box hanging, and because the hanging parts used to hook the boxes are located directly above the boxes, they interfere with the workers' ability to spray paint the boxes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hanging device for box painting, aiming to solve the problems that existing box hanging devices result in poor box hanging stability, and that the hanging parts used to hook the box are located directly above the box, which interferes with the operator's technical skills in box painting.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a hanging device for spraying a box, including an aerial track, a hanger, and multiple traveling mechanisms. Each traveling mechanism is connected to and can travel along the aerial track. The hanger includes connecting pipes and hanging members. Any two traveling mechanisms are connected to one connecting pipe. The first part of the connecting pipe connected to the traveling mechanism is located in the middle of the connecting pipe. Each connecting pipe is located below the aerial track, and the extension direction of each connecting pipe is perpendicular to the aerial track. Each connecting pipe has a hanging member connected to both ends. The second part of the connecting pipe connected to the two hanging members is located on both sides of the first part. The four hanging members are respectively connected to the four corners of the box to be sprayed, so that the box is suspended on the hanging members, and the distance between two connecting pipes is greater than the length of the box. The length direction of the box is perpendicular to the horizontal direction of the connecting pipe.

[0007] Furthermore, each of the connecting pipes is fixed with a plurality of first suspension blocks at intervals along its respective axial direction, and each first suspension block has a first connection hole at its lower end. The end of a hanging component facing away from the box is connected to a first connection hole.

[0008] Furthermore, the hanger also includes a double-headed hook, and the connecting pipe is connected to the traveling mechanism via the double-headed hook.

[0009] Furthermore, the two ends of the double-headed hook are respectively provided with an upper hook portion and a lower hook portion, and the connecting pipe is also provided with a second suspension block. The upper end of the second suspension block is provided with a second connecting hole, and the lower end of the walking mechanism is provided with a groove. The groove extends through the walking mechanism along the length direction of the box body. A connecting shaft extending along the axial direction of the connecting pipe is provided in the groove. The upper hook portion is located in the groove and is hooked and connected to the connecting shaft, and the lower hook portion is hooked and connected to the second connecting hole.

[0010] Furthermore, the hanging component is a double-headed hook.

[0011] Furthermore, the hanging component is a steel wire rope, and a carabiner is connected to one end of the steel wire rope for connecting with the first connecting hole. The steel wire rope is hooked and connected to the first connecting hole through the carabiner.

[0012] Furthermore, limit rings are provided at opposite ends of the connecting pipe fitting, and the limit rings are detachably connected to the connecting pipe fitting.

[0013] Furthermore, the limiting ring is threadedly connected to the connecting pipe fitting.

[0014] Furthermore, the overhead track is an I-beam track, and the walking mechanism includes two connecting seats, two rollers, and two clamping members. One end of the two connecting seats is clamped and fixed between the two clamping members, and the gap between the two connecting seats forms the groove. The rollers are rotatably mounted on the clamping members, and the two rollers clamp the I-beam track and can walk along the I-beam track.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model discloses a hanging device for spraying boxes. It connects to two traveling mechanisms via two connecting pipes, which move along an overhead track. The connecting pipes move along the track under the drive of the traveling mechanisms. Since each connecting pipe has two hanging brackets at opposite ends, there are four hanging brackets in total. These four hanging brackets are connected to the four corners of the box to be sprayed, thus stably suspending the box on the hanger. Furthermore, because the distance between the two connecting pipes is greater than the length of the box (which is perpendicular to the connecting pipes), the hanging brackets are not located directly above the box, effectively preventing interference with the spraying operation.

[0030] Please refer to Figure 1 - Figure 7This utility model provides a hanging device for spraying paint boxes, including an overhead track 1, a hanger 2, and multiple traveling mechanisms 3. Each of the multiple traveling mechanisms 3 is connected to and can travel along the overhead track 1. The hanger 2 includes a connecting pipe 20, a double-headed hook 21, and a hanging member 22. Each pair of traveling mechanisms 3 is connected to a connecting pipe 20. The first part 223 of the connecting pipe 20, which connects to the traveling mechanism 3, is located in the middle of the connecting pipe 20. Each connecting pipe 20 is located below the overhead track 1, and the extension direction of each connecting pipe 20 is perpendicular to the overhead track 1. Each connecting pipe 20 has a hanging member 22 connected to both ends. In each connecting pipe 20, the second part 224, which connects to two hanging members 22, is located on both sides of the first part 223.

[0031] Four hanging brackets 22 are respectively connected to the four corners of the box 4 to be painted, so that the box 4 is suspended on the hanging brackets 22, and the distance between the two connecting pipes 20 is greater than the length of the box 4; wherein, the length direction of the box 4 is perpendicular to the horizontal direction of the connecting pipes 20.

[0032] In summary, this utility model connects to two traveling mechanisms 3 via two connecting pipes 20. Since the traveling mechanisms 3 can move along the overhead track 1, the connecting pipes 20 can move along the overhead track 1 under the drive of the traveling mechanisms 3. Furthermore, since each connecting pipe 20 has two hanging parts 22 connected to its opposite ends, there are four hanging parts 22 for each connecting pipe 20. These four hanging parts 22 are connected to the four corners of the box 4 to be painted, thus stably suspending the box 4 on the hanger 2. Additionally, since the distance between the two connecting pipes 20 is greater than the length of the box 4, and the length of the box 4 is perpendicular to the horizontal direction of the connecting pipes 20, the hanging parts 22 are not located directly above the box 4, effectively avoiding interference with the worker's painting of the box 4.

[0033] In this embodiment, each connecting pipe 20 is fixed with a plurality of first suspension blocks 221 at intervals along its respective axial direction. Each first suspension block 221 has a first connection hole 2210 at its lower end. One end of a hanging piece 22 facing away from the box 4 is connected to a first connection hole 2210. This facilitates quick connection between the hanging piece 22 and the connecting pipe 20 and makes disassembly convenient.

[0034] In this embodiment, the connecting pipe 20 is connected to the traveling mechanism 3 via the double-headed hook 21. Specifically, the double-headed hook 21 has an upper hook portion 210 and a lower hook portion 211 at its two ends. The connecting pipe 20 is also provided with a second suspension block 222, the upper end of which has a second connecting hole 2220. The lower end of the traveling mechanism 3 has a groove 320, which extends through the traveling mechanism 3 along the length of the housing 4. A connecting shaft 321 extending axially along the connecting pipe 20 is provided within the groove 320. The upper hook portion 210 is located within the groove 320 and hooks onto the connecting shaft 321, while the lower hook portion 211 hooks onto the second connecting hole 2220. Thus, the double-headed hook 21 allows for quick connection between the connecting pipe 20 and the traveling mechanism 3, and also facilitates the removal of the connecting pipe 20 from the traveling mechanism 3 for convenient use.

[0035] In this embodiment, the hanging component 22 is a steel wire rope. A carabiner 225 is attached to one end of the steel wire rope for connection to the first connecting hole 2210 on the connecting pipe 20. The steel wire rope is hooked to the first connecting hole 2210 on the connecting pipe 20 via the carabiner 225, facilitating quick assembly and disassembly of the steel wire rope from the connecting pipe 20. Of course, in other embodiments, the hanging component 22 can also be a double-ended hook.

[0036] It should be noted that the connecting pipe 20 is a steel pipe. By setting multiple first suspension blocks 221 on each connecting pipe 20, it can be used for hanging boxes 4 of different sizes, thus improving applicability.

[0037] In this embodiment, limiting rings 220 are provided at opposite ends of the connecting pipe 20. The limiting rings 220 are detachably connected to the connecting pipe 20. In this embodiment, the limiting rings 220 are threadedly connected to the connecting pipe 20, which allows for quick assembly and disassembly of the limiting rings 220 and the connecting pipe 20. The limiting rings 220 prevent the first suspension block 221 and the second suspension block 222 from detaching from the connecting pipe, thereby effectively preventing the housing 4 from falling due to the first suspension block 221 detaching from the connecting pipe 20.

[0038] In this embodiment, the aerial track 1 is an I-beam track, and the walking mechanism 3 includes two connecting seats 30, two rollers 31, and two clamping members 32. One end of each connecting seat 30 is clamped and fixed between the two clamping members 32. The gap between the two connecting seats 30 forms the groove 320. The rollers 31 are rotatably mounted on the clamping members 32. The two rollers 31 clamp the I-beam track and can walk along it. Therefore, by driving the rollers 31 to walk along the I-beam track, the box 4 can be moved into or out of the spraying area.

[0039] In this embodiment, refer to Figure 7 Each walking mechanism 3 has a connecting seat 30 connected by an iron chain 33. The iron chain 33 is driven by the power unit to move along the I-beam track.

[0040] In summary, 1. Using the hanging device for box painting of this utility model to hang the box 4 can improve the stability and ease of operation of the box 4, significantly improve the painting efficiency and product quality, and is suitable for efficient painting operations of various boxes 4. Moreover, it has low manufacturing cost and high versatility.

[0041] 2. After the coating of the box body 4 is completed, it needs to be moved to the oven for drying. Since the coating area of ​​the box body 4 is some distance away from the oven, if the box body 4 shakes during the process of moving it to the oven after coating, the coating powder on the box body 4 will fall off, resulting in powder shedding. However, the box body coating hanging device of this utility model uses a four-corner positioning structure of the box body 4, which will not cause the box body 4 to shake and fall off during the movement. Moreover, the four-corner positioning box body structure is tough and facilitates the balance of the box body.

[0042] 3. Compared with the traditional box spraying method, which mainly uses a trolley to place and fix the box, the hanging device for box spraying of this utility model eliminates blind spots during box spraying and is easy to operate. Moreover, the spraying process after hoisting can standardize the spraying process of box 4, which greatly saves on the use of spray powder, especially the bottom spraying difference of box 4, which greatly saves spray powder.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
