Technical Field

[0001] This invention relates to cleaning tools for strip steel production, and in particular to a special tool for online cleaning of roll surfaces. Background Technology

[0002] In continuous strip steel production lines, the rollers that have the most contact with the strip steel are various types of rollers, such as tension rollers, guide rollers, alignment rollers, and looper rollers. The surface quality of these rollers directly affects the quality of the strip steel. With the development of steel rolling technology, continuous lines can now produce strip steel as thin as 0.12mm, which places even higher demands on the cleanliness of the roller surfaces. Foreign matter adhering to the roller surfaces can cause periodic roller marks on the strip steel surface, affecting its quality.

[0003] Traditional online cleaning of looper top rollers requires cleaning tools to enter from the middle of the strip on both sides of the roller. Due to limitations in space, ordinary fixed-end cleaning tools are tilted when they come into contact with the roller surface, and the tilt angle varies depending on the operator's position and equipment layout. Therefore, ordinary tools have poor adaptability and can only achieve point contact with the roller surface. This not only results in poor cleaning effect but also uneven force on the tool contact surface, posing a significant safety risk. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] Please see Figure 1-4 The present invention provides a technical solution for a special tool for online cleaning of roller surfaces: a special tool for online cleaning of roller surfaces includes a telescopic rod 1, and a universal scraper mechanism 2 is installed at the top of the telescopic rod 1;

[0028] The universal scraper mechanism 2 includes a scraper 21, a fixing plate 22, and a fastening bolt 23. The fixing plate 22 is fixedly connected to the top end of the telescopic rod 1. The scraper 21 has a mounting hole in the center, and the fixing plate 22 has a through hole. The bolt 23 passes through the mounting hole of the scraper 21 and the through hole of the fixing plate 22 in sequence, so that the scraper 21 is pivotally connected to the fixing plate 22.

[0029] In this embodiment, the telescopic rod 1 is provided, which can be freely adjusted to suit different working conditions of cleaning the roller surface. A hole is made in the center of the scraper 21, and it is connected to the fixing plate 22 by fastening bolt 23. During installation, the screw is tightened to fix the scraper 21 but not tightened. This ensures that the scraper 21 can rotate automatically after contacting the roller surface and being subjected to force during use, so that the scraper 21 surface and the roller surface can make horizontal contact, which can more effectively clean the roller surface. The scraper 21 is installed on the fixing plate 22. The fastening bolt 23 here is an M10*30 screw with a flat washer. In order to avoid the screw being too long and scratching the strip steel when cleaning the roller surface, the length of the screw should not exceed 35mm.

[0030] Furthermore, the telescopic rod 1 includes: a first telescopic sleeve 11, a second telescopic sleeve 12 slidably connected inside the first telescopic sleeve 11, a third telescopic sleeve 13 slidably connected inside the second telescopic sleeve 12, and an elastic limiting bolt 14 is provided between the first telescopic sleeve 11 and the second telescopic sleeve 12, and between the second telescopic sleeve 12 and the third telescopic sleeve 13.

[0031] In this embodiment, the telescopic rod 1 is provided, and its length can be freely adjusted to suit different cleaning roller surfaces and flexible adaptation to all cleaning scenarios from short distance to long distance. The operator can quickly adjust the length of the connecting rod according to the specific height of the roller, so that the cleaning head can accurately and stably reach and contact the target roller surface, completely solving the cleaning blind spot caused by height changes. The telescopic rod 1 includes a first telescopic sleeve 11, wherein the second telescopic sleeve 12 and the third telescopic sleeve 13 can extend and retract axially relative to the first telescopic sleeve 11, and the extension and retraction stroke of the second telescopic sleeve 12 and the third telescopic sleeve 13 can be sequentially limited by the elastic limit bolts 14.

[0032] Furthermore, a fixed sleeve 3 is fixedly connected to the third telescopic sleeve 13, and two clamps are symmetrically arranged on the fixed sleeve 3. A flashlight 4 is installed in the groove of each clamp.

[0033] In this embodiment, a fixing sleeve 3 and a flashlight 4 are provided to illuminate the roller surface, making it easier for workers to spot foreign objects adhering to the roller surface. The flashlight 4 can be detachably fixed by clamps on both sides, providing illumination when cleaning with the two different scraping surfaces of the scraper 21.

The nozzle 5 is provided with a nozzle 6 at one end near the universal scraper mechanism 2, and a water pipe connector 7 is provided at the other end of the nozzle 5 away from the nozzle 6.

[0035] In this embodiment, a spray pipe 5 is fixed on the third telescopic sleeve 13. When foreign objects such as zinc slag on the roller surface are difficult to remove manually, an external cleaning device can be connected through the water pipe connector 7. The external cleaning agent is sprayed onto the foreign objects on the roller surface through the nozzle 6. A special weak acid cleaning agent or metal cleaning agent is used to spray, causing the foreign objects such as zinc slag to undergo a chemical reaction and loosen. Then, the scraper 21 is used to remove them, which reduces the intensity of manual labor and effectively reduces physical damage to the roller surface substrate.

[0036] Specifically, a handle 8 is fixedly connected to the bottom of the first telescopic sleeve 11. The center of the handle 8 is welded to the first telescopic sleeve 11 in a T-shape. A handle sleeve 9 is provided at both ends of the handle 8.

[0037] In this embodiment, a handle 8 is provided to facilitate operation by the staff and improve the force distribution effect. A handle sleeve 9 is provided on the handle 8 to ensure the comfort of holding the handle 8.

[0038] In addition, the scraper 21 is made of stainless steel, and each scraper 21 has a symmetrical inclined scraping surface.

[0039] In this embodiment, in order to ensure the cleaning effect of the roller surface and ease of use, the scraper 21 is made of stainless steel, and both sides of the long side of the scraper 21 can be used for scraping.

[0040] In addition, the top end of the third telescopic sleeve 13 is flat, and a slot is provided on the flat part of the third telescopic sleeve 13. The fixing piece 22 is located in the slot, and the two are welded together.

[0041] In this embodiment, the top end of the third telescopic sleeve 13 is flat. In order to ensure the welding strength between the fixing piece 22 and the third telescopic sleeve 13, a slot is provided on the flat part of the third telescopic sleeve 13. The fixing piece 22 is located in the slot and the two are welded together to increase the welding area and ensure the structural stability.

[0042] It should be noted that the top of the fixing piece 22 is arc-shaped.

[0043] In this embodiment, the top of the fixing plate 22 is designed to be arc-shaped to ensure that the scraper can rotate flexibly when using the tool.

[0044] 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, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
