For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0030] In view of the high frequency of equipment shutdown on site, the cleaning of the contact rods is completely dependent on manual cleaning, which is labor-intensive and has high safety risks (height work is required). Figure 1 , Figure 2 As shown, the embodiment of the utility model provides a device for cleaning oil dirt of a sling connecting rod, comprising a cleaning structure 1, which comprises a base 11 and a connecting plate 12. One end of the connecting plate 12 is rotatably connected to the base 11, and the other end of the connecting plate 12 is provided with a cleaning wheel 13. A positioning adjustment mechanism is provided between the connecting plate 12 and the base 11, so that the angle between the connecting plate 12 and the base 11 can be adjusted and fixed after adjustment.
[0031] like Figure 3As shown, when the sling connecting rod cleaning oil stain device provided by the embodiment of the utility model is in use, the angle between the connecting plate 12 and the base 11 is adjusted by the positioning adjustment mechanism, so that the cleaning wheel 13 at the end of the connecting plate 12 can be against the connecting rod 2 of the sling passing by, and then the position of the connecting plate 12 is fixed. When the sling connecting rod 2 passes through the cleaning wheel 13, the oil stains on the connecting rod 2 of the sling are absorbed and wiped clean by the cleaning wheel 13. In addition, since the running direction of the sling is consistent with the normal rotation direction of the cleaning wheel 13, the normal operation of the sling is unobstructed and does not affect the normal operation of the equipment. The cleaning wheel 13 of the sling connecting rod cleaning oil stain device provided by the embodiment of the utility model is detachable and can be replaced periodically to ensure the reliability of the cleaning oil stain device. In addition, the angle between the connecting plate 12 and the base 11 can be adjusted by the positioning adjustment mechanism, which can ensure that the cleaning wheel 13 has sufficient pressing force on the connecting rod 2 of each sling without affecting its normal operation, thereby ensuring the cleaning effect. The entire oil cleaning device adopts a purely mechanical structure, does not require power, and has a low manufacturing cost.
[0032] like Figure 1 , Figure 2 As shown, in one embodiment of the utility model, the positioning adjustment mechanism includes an adjustment plate 14 and an adjustment bolt 15. One end of the adjustment plate 14 is fixedly connected to the connecting plate 12, and the other end is connected to the base 11 through the adjustment bolt 15. The adjustment plate 14 and the base 11 are respectively provided with corresponding through holes, and the adjustment bolt 15 is slidably arranged in the two through holes. The adjustment bolt 15 is provided with a bolt head and an adjustment nut 16, and the bolt head and the adjustment nut 16 are respectively located on the outside of the base 11 and the adjustment plate 14. An elastic member is provided between the base 11 and the adjustment plate 14 to keep the adjustment plate 14 away from the base 11. By rotating the adjustment nut 16 to move away from or close to the bolt head of the adjustment bolt 15, the angle between the connecting plate 12 and the base 11 can be adjusted, and it can be ensured that the cleaning wheel 13 has sufficient pressing force on each hanger connecting rod without affecting its normal operation, thereby ensuring the cleaning effect.
[0033] Specifically, the elastic member can be a spring 17, which is compressed and sleeved on the outer periphery of the adjusting bolt 15, and the two ends of the spring 17 are respectively against the adjusting plate 14 and the base 11. When the connecting rod of the sling pushes the cleaning wheel 13, due to the action of the spring 17, the cleaning wheel 13 can always maintain pressure on the sling connecting rod to ensure the cleaning effect. The sling connecting rod oil cleaning device provided in this embodiment is a non-powered mechanical mechanism, which relies on the compressed spring 17 to open the cleaning wheel 13. If a fault or other special circumstances occur, the opening can be manually adjusted to block the use of the cleaning structure 1.
[0034] In one embodiment of the utility model, the outer periphery of the cleaning wheel 13 is provided with dirt-absorbing cotton to absorb and wipe the oil stains on the sling connecting rod, and when the dirt-absorbing cotton absorbs enough oil stains, only the dirt-absorbing cotton needs to be replaced without replacing the entire dirt-absorbing wheel 13, which can save costs.
[0035] like Figure 1 , Figure 2 As shown, in one embodiment of the utility model, two parallel mounting plates 18 are fixedly provided on the base 11, and the mounting plates 18 are perpendicular to the base 11. One end of the connecting plate 12 is located between the two mounting plates 18 and is connected to the two mounting plates 18 through a first pin 121. Further, the connecting plate 12 includes two parallel support plates 120, and the cleaning wheel 13 is disposed between the ends of the two support plates 120 and is connected through a second pin 122.
[0036] like Figure 4-Figure 6 As shown, in a preferred embodiment of the utility model, the number of the cleaning structures 1 is two, and they are symmetrically arranged so that the cleaning wheels 12 of the two cleaning structures 1 are close to each other. In this embodiment, the two cleaning structures 1 can be arranged on both sides of the connecting rod 2 of the spreader, and the oil stains on both sides of the connecting rod 2 of the spreader can be absorbed and wiped respectively, which greatly improves the cleaning effect of the connecting rod 2 of the spreader. Furthermore, the distance between the cleaning wheels 13 of the two cleaning devices is less than the diameter of the connecting rod 2, so that the two cleaning wheels 13 tightly clamp the connecting rod 2 of the spreader between them to improve the cleaning effect. The present embodiment is designed with two friction cleaning wheels 13, and the spacing between the two cleaning wheels 13 is adjustable, which is adjusted to be slightly smaller than the width of the connecting rod 2 of the sling. When the connecting rod 2 of the sling enters between the two cleaning wheels 13, the cleaning wheels 13 are pushed open (the spring 17 is compressed) to achieve a cleaning effect. The detachable cleaning wheels 13 are detachable and are connected to the connecting plate 12 via a second pin shaft 122, so that they can be replaced periodically to ensure the reliability of the oil cleaning device.

[0038] 1) The oil cleaning device for the sling connecting rod provided in the embodiment of the utility model can realize the automatic cleaning function of the sling, reduce the alarm and end-of-line stoppage caused by the sling slippage, and the cost saving obtained by reducing the periodic stoppage time is calculated as follows: 26.77 (hourly average wage) × 26 (days) × 12 (months) / 3600 (seconds) × 120 (seconds) × 2 (shifts) × 1000 people = 556816 yuan;
[0039] 2) The oil cleaning device for the connecting rod of the spreader provided in the embodiment of the utility model can realize the self-cleaning function, reduce the labor cost, reduce the high-risk operation, and greatly improve the ergonomics;
[0040] 3) The oil cleaning device for the sling connecting rod provided by the embodiment of the utility model has a simple structure, low manufacturing cost, long service life and convenient maintenance;
