Description

Technical Field

[0001] The present invention relates to the technical field of dry hanging of porcelain enamel steel plates, and specifically relates to a dry hanging device for the production of porcelain enamel steel plates. Background Art

[0002] Porcelain enamel steel plates are composite materials formed by firmly bonding high-quality steel plates and special functional inorganic non-metallic materials through a new electrostatic dry powder enameling process and high-temperature firing, so that a strong chemical bond is formed between the high-quality steel plates and the special functional inorganic coatings. Porcelain enamel steel plates have become the first choice for interior landscape design in underground spaces due to their unique porcelain texture, flame retardancy, moisture resistance, acid and alkali resistance, modular structure, safety, and low maintenance costs, and are widely used.

[0003] In the prior art, when installing steel plates through a dry hanging device, they are installed one by one from bottom to top. During the hanging process, the steel plates will first move up to the hooks and then be lowered. After that, the steel plates beside and above are installed. Although this installation method is firm, when the steel plate below is damaged and needs to be removed, the steel plates above need to be removed one by one before the steel plate below can be removed, which greatly increases unnecessary operations and is time-consuming and laborious. Therefore, we propose a dry hanging device for the production of porcelain enamel steel plates. Summary of the Invention

Embodiment

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0030] Please refer to Figure 1 - Figure 2 , as shown in the figure, a dry hanging device for the production of porcelain enamel steel plates includes a porcelain enamel steel plate body 1, a plugging device 3, a fixing device 4, an operating device 5, and a mounting bracket 2 for fixing on the wall surface. The plugging device 3 is installed on the porcelain enamel steel plate body 1 and the mounting bracket 2 for preliminarily fixing the porcelain enamel steel plate body 1 and the mounting bracket 2. The fixing device 4 is installed on the porcelain enamel steel plate body 1 for automatically limiting the plugging device 3 at the end of the installation, making the installation more tightly and stably. The operating device 5 is installed on the porcelain enamel steel plate body 1 for releasing the fixation of the internal fixing device 4 and transporting the porcelain enamel steel plate body 1 when the porcelain enamel steel plate body 1 needs to be disassembled and assembled.

[0031] Please refer to Figure 2 - Figure 5 , as shown in the figure, the plugging device 3 includes a device pipe 6 fixedly installed in the middle of one side of the porcelain enamel steel plate body 1. A first plugging pipe 7 that is inserted into the device pipe 6 is fixedly connected to the mounting bracket 2. Installation pipes 8 are fixedly connected to the four corners of one side of the porcelain enamel steel plate body 1. Four groups of second plugging pipes 9 that are respectively inserted into the four groups of installation pipes 8 are fixedly connected to the mounting bracket 2.

[0032] In this embodiment, while quickly taking the porcelain enamel steel plate body 1 by the operating device 5, the device pipe 6 is inserted into the first plugging pipe 7, and the four groups of installation pipes 8 are inserted into the second plugging pipes 9, then the porcelain enamel steel plate body 1 can be quickly pre-installed. At this time, the operating device 5 will retract the fixing device 4 to facilitate direct plugging installation. After the plugging is completed, the operating device 5 is removed. At this time, the fixing device 4 automatically limits the position, enabling secondary fixing and expansion between the installation pipe 8 and the second plugging pipe 9, improving the stability of the fixation. The surface of the porcelain enamel steel plate body 1 after removing the operating device 5 is flat and smooth, more beautiful. At the same time, when a certain porcelain enamel steel plate body 1 needs to be replaced, directly adsorb the porcelain enamel steel plate body 1 through the operating device 5 while releasing the limit of the fixing device 4, and pulling the operating device 5 can directly remove the porcelain enamel steel plate body 1 from the mounting bracket 2. The operation is not affected by the surrounding porcelain enamel steel plate bodies 1, and it is faster and more convenient. Embodiment

[0033] Please refer to Figure 2 - Figure 8Description of Embodiment 2: This embodiment further elaborates on Embodiment 1. In the illustration, the fixing device 4 includes a device disk 10 slidably connected to the inner wall of the device tube 6. A first tension spring 11 fixedly connected to one end of the device tube 6 is fixedly connected to the side of the device disk 10. Four connecting tubes 12 fixedly connected to four installation tubes 8 respectively are fixedly connected to the side of the device tube 6. A fixing block 13 is fixedly connected inside the installation tube 8. An arc-shaped tube 14 communicating with the connecting tube 12 is fixedly connected to the fixing block 13. The fixing block 13 is provided with a plugging member 15 for plugging the installation tube 8 into the second insertion tube 9 after the operation of the operating device 5 is completed. The arc-shaped tube 14 is provided with an expansion member 16 for pushing the gas in the device tube 6 through the connecting tube 12 to expand the plugging member 15 when the first tension spring 11 pulls the device disk 10, making the plugging limit more stable. The device disk 10 is provided with a limiting member 17 for driving the device disk 10 to pull the first tension spring 11 when using the operating device 5, and making the first tension spring 11 pull the device disk 10 and limit the device disk 10 after the operation is completed. The device disk 10 is provided with a release member 18 for releasing the plugged state of the plugging member 15 and the expanded state of the expansion member 16 when the operating device 5 drives the device disk 10 to pull the first tension spring 11.

[0034] Please refer to Figure 3 - Figure 10 , in the illustration, the plugging member 15 includes a sliding block 19. One end of the arc-shaped tube 14 is fixedly connected to a sliding tube 20. The sliding tube 20 passes through the sliding block 19 and is slidably connected to the inner wall of the sliding block 19. A sliding groove 21 slidably connected to the outer wall of the sliding block 19 is formed on the installation tube 8. One end of the sliding block 19 is rotatably connected to multiple rotating blocks 22 at equal intervals. Plugging blocks 23 are fixedly connected to the multiple rotating blocks 22. A plugging hole 24 for plugging the plugging blocks 23 is formed on the side of the second insertion tube 9. Anti-slip grooves 25 are formed on the side of the plugging blocks 23.

[0035] Please refer to Figure 3 - Figure 10 , in the illustration, the expansion member 16 includes an airbag 26. The outer wall of the airbag 26 is fixedly connected to the inner walls of the multiple plugging blocks 23. A sleeve 27 slidably connected to the inner wall of the sliding tube 20 is communicated and connected to the side of the airbag 26. An air hole 28 for balancing the air pressure inside the device tube 6 is formed on the side of the device tube 6 near one end of the porcelain enamel steel plate body 1.

[0036] In this implementation, during installation, the operating device 5 drives the device disk 10 to pull the first tension spring 11. At this time, the releasing member 18 pulls to make the sliding block 19 slide into the installation pipe 8. At this time, the device disk 10 evacuates the connecting pipe 12, so that the arc-shaped pipe 14 and the sliding pipe 20 evacuate the air in the sleeve 27 and the airbag 26. The airbag 26 contracts, so that the sliding block 19 drives the plug-in block 23 to slide into the sliding groove 21 as a whole. At this time, the outer wall of the installation pipe 8 is a smooth circular ring, which is convenient for plugging and fixing with the second plug-in pipe 9. After the plugging is completed, the operation of the operating device 5 is released. The first tension spring 11 pulls the device disk 10 to slide in the reverse direction. The releasing member 18 no longer pulls the sliding block 19, and the sliding block 19 slides out of the sliding groove 21 and is inserted into the insertion hole 24, so that the installation pipe 8 and the second plug-in pipe 9 are initially limited. At the same time, when the device disk 10 moves, the gas in the device pipe 6 will be pushed into the sleeve 27 through the connecting pipe 12 and enter the airbag 26. The airbag 26 gradually expands, so that the plug-in block 23 can rotate around the rotating block 22, and the top of the plug-in block 23 gradually unfolds. The anti-slip groove 25 is closely attached to the inner wall of the insertion hole 24, making the limit more stable and tight, and preventing loosening and shaking during use. Embodiment

[0037] Please refer to Figure 3 - Figure 4 and Figure 10 Referring to Embodiment 3, this embodiment further describes Embodiment 1. The releasing member 18 in the figure includes four groups of first ropes 29 fixedly installed on the side of the device disk 10. One end of the first rope 29 away from the device disk 10 is fixedly connected to a connecting frame 30 fixedly connected to the inner wall of the sleeve 27. One end of the sliding block 19 is fixedly connected to a first spring 31 fixedly connected to the fixed block 13. The outer wall of the first rope 29 is slidably connected to the inner walls of the connecting pipe 12, the sliding pipe 20 and the sleeve 27.

[0038] Please refer to Figure 6 - Figure 12 Referring to the figure, the limiting member 17 includes a second tension spring 32 fixedly installed on the side of the device disk 10. The second tension spring 32 is fixedly connected to a driving disk 33 slidably connected to the inner wall of the device pipe 6. A plurality of limiting rods 34 are fixedly connected to the side of the driving disk 33. The plurality of limiting rods 34 all penetrate the device disk 10 and are slidably connected to the device disk 10. The driving disk 33 is made of magnetic metal material. The driving disk 33 is provided with a control member 35 for releasing the limit between the device disk 10 and the device pipe 6 when the driving disk 33 pulls the device disk 10 and restoring the limiting relationship when the driving disk 33 stops pulling.

[0039] Please refer to Figure 6 - Figure 12, in the illustrated control member 35 includes multiple groups of second draw ropes 36. Multiple groups of guide grooves 37 are provided on the side surface of the device disk 10. Multiple groups of clamping blocks 38 are slidably connected in the multiple groups of guide grooves 37. Multiple groups of helical grooves 39 that are engaged with the clamping blocks 38 are provided in the device tube 6. One side of the clamping block 38 is fixedly connected to a second spring 40 that is fixedly connected to the guide groove 37. One end of the second draw rope 36 is fixedly connected to the side surface of the driving disk 33, and the other end is fixedly connected to one end of the clamping block 38.

[0040] Please refer to Figure 1 and Figure 5 , in the illustrated operating device 5 includes an electromagnet 41. A handle 42 is fixedly connected to the electromagnet 41. The electromagnet 41 is used to adsorb the porcelain enamel steel plate body 1 and the driving disk 33.

[0041] In this embodiment, by turning on the electromagnet 41 to generate magnetism, adsorbing the middle part of the surface of the porcelain enamel steel plate body 1 can achieve the rapid grasping and handling of the porcelain enamel steel plate body 1. At the same time, the electromagnet 41 will adsorb the driving disk 33 at this time. The driving disk 33 pulls the second tension spring 32 and at the same time pulls the second draw rope 36. The second draw rope 36 pulls the clamping block 38 to move and compress the second spring 40 until the engagement between the clamping block 38 and the helical groove 39 is released. At this time, the device disk 10 can be pulled by the second tension spring 32. The device disk 10 slides and pulls the first tension spring 11, and the gas in the airbag 26 is pumped into the device tube 6 through the connecting pipe 12. At the same time, the device disk 10 moves and pulls the first draw rope 29. The first draw rope 29 slides in the connecting pipe 12, thereby pulling the connecting frame 30 so that the sleeve 27 and the sliding block 19 slide together towards the fixed block 13, compressing the first spring 31, and the retraction of the plug block 23 can be completed. When the installation pipe 8 and the second insertion pipe 9 are completed and fixed, at this time, the magnetism of the electromagnet 41 is released, the porcelain enamel steel plate body 1 can be released and the pulling of the driving disk 33 can be released at the same time. The first tension spring 11 pulls the device disk 10 to move in the reverse direction. The clamping block 38 continuously slides and engages in the helical groove 39. The first draw rope 29 becomes loose, so that the first spring 31 rebounds to push the sliding block 19 and the plug block 23 out to complete the preliminary insertion with the insertion hole 24. The device disk 10 pushes the gas in the device tube 6 into the airbag 26 through the connecting pipe 12, and the secondary expansion and fixation can be realized. The driving disk 33 is pulled back by the second tension spring 32, and the overall area is stable. At this time, the clamping block 38 will engage with the helical groove 39 to prevent the first tension spring 11 from becoming loose after long-term use and the pulling force on the device disk 10 decreases, resulting in unstable inflation of the airbag 26, making the fixation more reliable and preventing loosening.
