Abstract
Description
Technical Field
[0001] This utility model relates to the field of refractory material spraying technology for tundishes, specifically a portable spraying device for spraying refractory materials for tundishes. Background Technology
[0002] The refractory material spraying operation of tundish is an important part of the steel smelting process. Its purpose is to form a refractory layer on the inner wall of the tundish to protect it from the corrosion of high-temperature molten steel. With the development of the steel industry and the progress of technology, the requirements for refractory material spraying operations of tundish are also getting higher and higher.
[0003] According to the patent application published on the Internet, "A transferable spraying device for spraying refractory materials in a tundish (authorization announcement number: CN 221493003 U)" describes "This utility model is a transferable spraying device for spraying refractory materials in a tundish, wherein the frame structure is transferably assembled to the upper opening of the continuous casting tundish; during operation, the bottom support of the frame structure is positioned on the upper opening of the tundish; the base of the spraying robotic arm is positioned in the frame structure, and during operation, the nozzle of the spraying robotic arm is located inside the continuous casting tundish. It also includes at least one auxiliary mechanism."
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] In use, this utility model acquires three-dimensional image data of the inner surface of the tundish using a multi-view camera to facilitate the formation of a spraying plan. Then, the spraying robotic arm is controlled to spray refractory material onto the inner surface of the tundish according to the formed spraying plan. During spraying, a depth camera located at the front end of the spraying robotic arm collects three-dimensional image data of the current position in real time, thereby achieving precise control of the spraying amount. However, in actual use, when this device acquires three-dimensional image data of the tundish using a multi-view camera, the powder is easily dispersed in the air during the spraying process, which can cause some of the spraying powder to cover the lens of the multi-view camera, thus affecting the normal operation of the multi-view camera and preventing it from completing a three-dimensional scan of the interior of the tundish. This further affects the spraying work and makes it impossible to complete precise spraying. Therefore, it is necessary to improve a portable spraying device for spraying refractory materials on tundishes. Utility Model Content

[0031] Example 1:
[0032] Based on existing technology, when this device acquires 3D image data of the intermediate package using a multi-view camera, the powder easily disperses in the air during the spraying process, causing some of the powder to cover the multi-view camera lens.

A connecting rod 819 is fixedly connected to the bottom of the rack 818, which facilitates the up-and-down movement of the cotton cloth strip 826 to clean the transparent plate 828, thereby preventing the sprayed powder from affecting the operation of the multi-view camera 7.
[0035] Furthermore, gear 816 meshes with the left side of rack 817, and rack 818 meshes with gear 816, which facilitates the movement of rack 818.
[0036] Furthermore, a groove is provided at the corresponding position of the limiting frame 812 and the rack 818, and the rack 818 is slidably connected in the groove, which facilitates limiting the movement of the rack 818.
[0037] Furthermore, the cleaning and protective component 82 includes a connecting frame 821, which is fixedly connected to the left and right sides of the connecting rod 819. A clip frame 822 is inserted inside the connecting frame 821, and a moving block 823 is slidably connected inside the connecting frame 821. A spring 824 is fixedly connected between the moving block 823 and the connecting frame 821. An installation plate 825 is fixedly connected to the outside of the clip frame 822. A cotton strip 826 is fixedly connected to the top of the installation plate 825. A protective frame 827 is fixedly connected to the inner wall of the back of the frame 1. A transparent plate 828 is fixedly connected to the bottom of the protective frame 827 to facilitate contact between the cotton strip 826 and the transparent plate 828, thereby cleaning the surface.
[0038] Furthermore, a slot is provided at the corresponding position of the card frame 822 and the moving block 823, and the moving block 823 is inserted into the slot. The cotton strip 826 is attached to the transparent plate 828, which makes it easy to disassemble and replace the cotton strip 826.
[0039] Example 2:
[0040] Given the current limitations of existing technologies in facilitating the observation of the spraying process, please refer to [link / reference]. Figure 7 Furthermore, in conjunction with Embodiment 1, the cleaning mechanism 11 includes a support frame 111, which is fixedly connected to the inner wall of the front of the frame 1. A motor 112 is fixedly connected to the back of the support frame 111. A rotating rod 113 is fixedly connected to the output end of the motor 112. A locking post 114 is fixedly connected to the front of the rotating rod 113. An adjustment frame 115 is movably connected to the outside of the locking post 114. A cotton strip 116 is fixedly connected to the front of the adjustment frame 115 to facilitate cleaning of the transparent observation plate 2, thereby facilitating observation by staff.
[0041] Furthermore, a groove is provided at the corresponding position of the frame 1 and the adjustment frame 115, and the adjustment frame 115 is slidably connected in the groove to facilitate the movement of the second cotton strip 116.
[0042] In actual operation, when the device is in use, firstly, it is connected to the connecting hook 3 on the frame 1 using the existing hoisting method, thereby moving the entire device to the top of the intermediate tundish 6 to be sprayed. Then, the multi-view camera 7 is activated to acquire three-dimensional image data of the inner surface of the intermediate tundish 6. Next, the existing spraying equipment is connected to the spray head 9, and the rotating robotic arms 4 and 5 are activated to move the corresponding smoothing workpiece 10 and the spray head 9, thereby completing the spraying work on the inner surface of the intermediate tundish 6. Simultaneously... The movable cleaning and protection mechanism 8 is activated by starting the electric push rod 813, which pulls the connecting block 814 to move. This causes the connecting block 814 to pull the connecting plate 815 to move synchronously. During the movement of the connecting plate 815, the gear 816 is rotated. As the gear 816 moves, it is restricted by the rack 817, causing it to rotate. During this rotation, the rack 818 moves downward, which in turn pulls the connecting rod 819 downward. The connecting rod 819 then moves the corresponding cotton strips 8 on both sides downward. 26 moves downwards, causing the cotton strip 826 to wipe the surface of the transparent plate 828, thus preventing airborne spray powder from covering the lens of the multi-view camera 7. Simultaneously, during the later spraying process, workers can observe the spraying through the transparent viewing window. The cleaning mechanism 11 activates the motor 112, which drives the rotating rod 113 to rotate. The rotating rod 113 then pushes the locking pin 114 to move, causing the locking pin 114 to move and push the adjusting frame 115 to move. The adjusting frame 115 then synchronously pushes the second cotton strip 116 to move, causing the second cotton strip 116 to move... 6. Quickly clean the back of the transparent observation plate 2. After the device has been used for a long time, manually pull down the moving block 823 to completely disengage it from the frame 822, thereby pulling out the mounting plate 825 and the cotton strip 826. This allows the frame 822 to be quickly separated from the connecting frame 821, making it easier for staff to replace the cotton strip 826 and preventing it from becoming ineffective after prolonged use. In addition, during the later cleaning process, the cleaning effect can be further improved by manually spraying chemical agents such as alcohol in conjunction with the cotton strip 826.
