[0029] The rotating shaft 26 is U-shaped. The guide wheel 2 is rotatably connected to the bottom of the rotating shaft 26. Two limiting blocks 27 are fixedly protruding from the bottom of the rotating shaft 26. The guide wheel 2 is located between the two limiting blocks 27.

The drain cover 33 is detachably connected to the water outlet in a sealed manner.

[0032] The present invention also provides an automatic pickling treatment method for steel wire rope, which includes the following steps: Step 1: Pre-treatment of the wire rope: Check the appearance for severe corrosion, oil stains or other impurities; Step 2, pre-acid washing; at room temperature, immerse the wire rope in acid bath 1 with a hydrochloric acid concentration of 3%~8%; Step 3, secondary pickling: Under room temperature conditions, immerse the steel wire rope in acid pool 1 with a hydrochloric acid concentration of 8%~14%; Step 4, water washing: Under room temperature conditions, immerse the steel wire rope in a water washing tank with a pH value of 3~7 for water washing; Step 5, Phosphating: Immerse the steel wire rope in the phosphating bath and phosphate it at a temperature of 70-90 degrees Celsius. Step 6, water washing: Under room temperature conditions, immerse the steel wire rope in a water washing tank with a pH value of 6~7 for water washing; Step 7, Saponification: Immerse the steel wire rope in a saponification tank with a pH value of 8-12 for saponification, and control the temperature at 85-95 degrees Celsius.

[0033] In Example 1, before pickling, a steel wire rope is installed, passing through the threading hole 6, around the left limiting wheel 3, and then into the acid tank 1. It is then positioned at the bottom of the acid tank 1 by the guide wheel 2, and finally exits from the right limiting wheel 3. As the steel wire rope moves and is conveyed within the acid tank 1, it will drive the guide wheel 2 and the limiting wheel 3 to rotate. An appropriate amount of pickling solution is added to the acid tank 1, covering the portion of the steel wire rope at the bottom. After the steel wire rope passes through the threading hole 6, several roller brushes 7 rotate simultaneously to clean the surface of the steel wire rope. The rotation of the roller brushes 7 helps remove impurities, especially highly adhered stains and rust. Compared to ordinary wiping, the cleaning power is greater, thus improving the pickling effect.

[0034] In Example 2, in Example 1 above, the control system controls the servo motor 8 to work, which drives the driven synchronous pulley 11 to rotate through the transmission belt 9, thereby causing the gear ring 12 to rotate synchronously. Then, through the meshing relationship between the gear ring 12 and the pinion 13, it drives several roller brushes 7 to rotate synchronously, thereby achieving the cleaning treatment of the steel wire rope surface.

[0035] In Example 3, following Example 1 above, it is assumed that in the initial state, the guide wheel 2 is located at the bottom of the acid tank 1. The control system controls the servo motor 28 to work, and the two rotating shafts 26 rotate synchronously by 180 degrees through belt drive, rotating the guide wheel 2 to the top of the acid tank 1, which facilitates the wire rope threading operation. After the threading is completed, the two rotating shafts 26 continue to rotate 180 degrees under the drive of the servo motor 28, so that the guide wheel 2 is reset, which makes it easier to press the wire rope into the bottom of the acid tank 1, thereby facilitating the rapid wire rope threading operation and improving the convenience of operation. The guide wheel 2 is located between two limit blocks, which helps to ensure the positional accuracy of the guide wheel 2 and improve the positional accuracy of the wire rope during threading.
