DETAILED DESCRIPTION

[0026] The utility model will be further described below with reference to the drawings.

[0027] As Figures 1 to 3 shown, the steel wire rope cleaning device of the embodiment of the utility model includes lubricator 1, conveying pipe 2 and oil supply mechanism 3, and the two ends of conveying pipe 2 are connected with lubricator 1 and oil supply mechanism 3 respectively, and oil inlet hole 100 is formed in lubricator 1, lubricator 1 includes two oppositely arranged first shells 11, and one side of the two first shells 11 is hinged and the other side is detachably connected through fastener, the inside of the two first shells 11 can form open-ended cavity, and sealing member 12 in the form of cylinder is arranged in the cavity.

[0028] After steel wire rope 6 passes through lubricator 1, it is clamped by sealing member 12 in the inside of lubricator 1, so that the two ends of lubricator 1 are sealed, and the inside of lubricator 1 forms annular space around steel wire rope 6, oil supply mechanism 3 can transport lubricating grease to the annular space in the inside of lubricator 1 through conveying pipe 2 and wrap steel wire rope 6, realize the infiltration of steel wire rope 6, and through pulling steel wire rope 6, good lubrication of steel wire rope 6 can be realized and waste and pollution caused by the overflow of lubricating grease are avoided.

[0029] In the embodiment, the sealing member 12 is an integral body, which is slightly shorter than the first shell 11, and therefore an oil inlet 200 is formed on the side of the sealing member 12 to communicate with the oil inlet hole 100, so that the lubricating grease can smoothly enter the inside of the sealing member 12 to infiltrate the steel wire rope 6.

[0030] In other embodiments, the sealing member 12 is designed in a segmented manner, and a plurality of sealing members 12 are arranged at intervals in the inside of the first shell 11 and do not block the oil inlet hole 100, so that the oil inlet 200 is not needed.

[0031] As shown in Figure 1 and Figure 2 , the first shell 11 is provided with a guide pulley 13 at each end, and a channel for the steel wire rope 6 to pass into the inside of the first shell 11 is formed between the two guide pulleys 13 at the same end. The guide pulley 13 can provide a guide for the steel wire rope 6, so that the steel wire rope 6 can more smoothly pass into and out of the lubricator 1, and friction between the steel wire rope 6 and the first shell 11 is avoided, reducing the resistance.

[0032] As shown in Figure 4 , the sealing member 12 includes a main body portion 121 and a plurality of first protrusions 122, and the plurality of first protrusions 122 are arranged at intervals along the inner side wall of the main body portion 121. The first protrusion 122 can more fully contact the surface of the steel wire rope 6, thereby achieving a good sealing effect and further reducing the risk of lubricating grease overflowing.

[0033] Further, a plurality of grooves 300 are formed at the end of the first protrusion 122 away from the main body portion 121, and second protrusions 1221 are formed on both sides of the groove 300. By forming a plurality of second protrusions 1221 on the first protrusion 122 by forming grooves 300, each second protrusion 1221 can play a certain sealing role, thereby achieving multiple sealing and further enhancing the sealing effect.

[0034] As shown in Figure 2 and Figure 3 , the outer surface of the first shell 11 is provided with a first lifting ring 14. The first lifting ring 14 can be passed through by the sling 4 to hoist and fix the lubricator 1, and the end of the sling 4 away from the lubricator 1 is fixed to a suitable fixed point. At least two slings 4 are used to pull the lubricator 1, and when the steel wire rope 6 is pulled, the friction causes the sling 4 to be tightened, so that the lubricator 1 remains stable.

[0035] As shown in Figure 1As shown, the side of the lubricator 1 through which the steel wire rope 6 passes is also provided with a cleaning mechanism 5, which includes a support frame 51 and an inner liner 52. The support frame 51 is annular, and the inner liner 52 is arranged inside the support frame 51. The inner liner 52 has good elasticity and can rub against the surface of the steel wire rope 6. The cleaning mechanism 5 is used to clean the steel wire rope 6 before it enters the lubricator 1, to ensure the cleanliness between the strands of the steel wire rope 6 and remove solid particles such as impurities and dust on the steel wire rope 6, so as to avoid the influence of these impurities on the lubrication effect.

[0036] As shown in Figure 5 and Figure 6 Further, the support frame 51 includes two oppositely arranged second housings 511, one side of the two second housings 511 is hinged and the other side is detachably connected by a fastener. The outer surface of the inner liner 52 is provided with a positioning groove, and the inner surface of the second housing 511 is provided with a positioning protrusion 512 which can be clamped into the positioning groove. After the support frame 51 is opened, the inner liner 52 can be placed therein, and after the support frame 51 is closed, the inner liner 52 is fixed.

[0037] In order to keep the cleaning mechanism 5 stable, the outer surface of the second housing 511 is provided with a second lifting ring 513. Through the lifting cable 4, the support frame 51 will not move with the steel wire rope 6 when the steel wire rope 6 is pulled.

[0038] As shown in Figure 1 and Figure 7 Further, the cleaning mechanism 5 also includes a cleaner 53 arranged on the side of the support frame 51 away from the lubricator 1. The cleaner 53 includes a cleaning ring 531 and a thimble (not shown in the figure) sleeved on the cleaning ring 531. The cleaning ring 531 includes three separable cleaning petals 5311. The center of the cleaning ring 531 is a cleaning hole 400 through which the steel wire rope 6 passes, and the hole wall of the cleaning hole 400 can be in close contact with the surface of the steel wire rope 6. By arranging the cleaner 53, the cleaning ability of the cleaning mechanism 5 to the steel wire rope 6 can be further enhanced. The shape of the cleaning petals 5311 is selected according to the size of the steel wire rope 6 to be cleaned, so as to ensure that the cleaning hole 400 can be in good contact with the surface of the steel wire rope 6, and better cleaning effect can be achieved.

[0039] As shown in Figure 1 The oil supply mechanism 3 includes an air pump 31 and an oil tank (not shown in the figure). The air pump 31 is connected with the oil tank, the oil tank contains lubricating grease, and the end of the delivery pipe 2 away from the lubricator 1 is connected with the air pump 31. Before the air pump 31 is used to deliver lubricating grease to the lubricator 1, the appropriate oil supply pressure needs to be set, so that the lubricating grease in the lubricator 1 has appropriate pressure to better wet the steel wire rope 6. Since the original air in the interior of the lubricator 1 will be squeezed out when the lubricating grease is delivered, the first housing 11 is also provided with a corresponding exhaust structure, which can adopt the form of a one-way valve, etc., so that the lubricating grease can fill the interior of the lubricator 1.
