[0041] Step 5: The tower crane recycles the steel wire rope body 16 and scrapes off the lubricating oil of the steel wire rope body 16;

[0042] Step 6. After completing the work, turn off the power.

[0043] Furthermore, a non-destructive grounding device for tower crane wire rope in a strong field environment works as follows:

[0044] The same number of the devices as the steel wire ropes are fixedly installed on the steel wire rope regulating device of the tower crane, so that each steel wire rope body 16 passes through an oil storage box 7, and the power is turned on. The grounded discharge disk 6 contacts the ground through its own gravity, and the steel wire rope lubricating oil is added to the oil storage box 7 through the oiling nozzle 15; when the tower crane is not working, the steel wire rope body 16 is completely retracted. When the tower crane starts to work, the steel wire rope body 16 is driven downward by the steel wire rope regulating device to be released. At this time, the steel wire rope body 16 moves downward relative to the oil storage box 7, and the electric heater 9 inside the heat insulation shell 8 is turned on at this time, and the electric heating The inner side of the heater 9 is fitted with the oil storage box 7, and the oil storage box 7 can be heated to melt the wire rope lubricating oil from a semi-solid state into a liquid state, so that the lubricating oil can be evenly applied to the wire rope body 16 through the oil-absorbing cotton 14, while the portion of the wire rope body 16 located on the upper side of the oil storage box 7 is not coated with lubricating oil. The conductive connecting ring 11 is in direct contact with the wire rope body 16, and the conductive connecting ring 11 is connected to the top of the grounding wire 5 through the line connecting groove 12, so that static electricity can be quickly discharged. The grounding wire 5 transmits static electricity to the ground through the grounding discharge disk 6 in contact with the ground, thereby preventing static electricity damage. When the tower crane is finished working, the wire rope body 16 is driven by the wire rope adjusting device to be retracted upwards. At this time, the wire rope body 16 moves upwards relative to the oil storage box 7. At this time, the dust that may be contaminated on the wire rope body 16 can be isolated by the bottom end of the oil-absorbing cotton 14, and part of the lubricating oil can be brushed off. Then, the residual lubricating oil on the outside of the wire rope body 16 can be scraped off by the oil scraper ring 13, and the scraped lubricating oil is stored in the oil storage box 7. Therefore, the part of the wire rope body 16 located on the upper side of the oil storage box 7 has no lubricating oil, and is in direct contact with the conductive connecting ring 11. During the working process, the wire rope The rope body 16 will also move up and down relative to the oil storage box 7, but the wire rope body 16 will not be completely released or retracted. At this time, relying on the lubricating oil pre-added in the oil storage box 7 and the lubricating oil scraped off by the oil scraper ring 13, the wire rope body 16 can be continuously scraped, static electricity is discharged, and oiled. This device can continuously scrape oil, discharge static electricity, and oil the wire rope during the operation of the tower crane, which can not only ensure that the wire rope is smooth enough during use, but also prevent the wire rope from being damaged by static electricity, greatly reduce the impact of the strong field environment on the wire rope, and ensure the service life of the wire rope.
