[0002] Steel wire rope is made by twisting multiple steel wires into strands, and then twisting a certain number of strands into a spiral rope with the rope core as the center. Steel wire rope is mainly twisted by a stranding machine.

[0003] In order to improve the wear resistance and corrosion resistance of the steel wire rope, lubricating grease is coated on the surface of the steel wire rope to lubricate the steel wire rope, thereby forming a waterproof and corrosion-resistant lubricating oil film on the surface of the steel wire rope to improve the wear resistance and corrosion resistance.

[0004] However, due to the presence of a spiral cavity between two adjacent strands of the wire rope, the amount of grease required at different locations on the surface of the wire rope is inconsistent, and the spiral cavity needs to be completely filled to form a complete lubricating oil film on the surface of the wire rope. The current method of applying lubricating grease on the surface of the wire rope is not easy to form a complete lubricating oil film on the surface of the wire rope, resulting in poor wear resistance and corrosion resistance of the wire rope.

[0017] Figure 1 The present invention is a schematic structural diagram of a wire rope lubricating grease coating device according to an embodiment of the present invention. DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Reference Figure 1As shown, the utility model provides a wire rope lubricating grease coating device, comprising: an integrated base 1, a heat-insulating sleeve 2, a temperature-control sleeve 3 and a shaping sleeve 4.

[0021] The heat preservation sleeve 2, the temperature control sleeve 3 and the shaping sleeve 4 are installed on the integrated base 1. The integrated base is rectangular. The heat preservation sleeve 2, the temperature control sleeve 3 and the shaping sleeve 4 are respectively arranged along the length direction of the integrated base 1.

[0022] The outside of the insulation sleeve 2 is coated with an insulation layer. The insulation sleeve 2 has a first closed end and a second closed end opposite to each other. The first closed end is provided with an inlet hole for the steel wire rope 6 to pass through. The second closed end is provided with an outlet hole. The aperture size of the inlet hole is adapted to the diameter size of the steel wire rope 6. The aperture size of the outlet hole is larger than the outer diameter size of the steel wire rope 6. The insulation sleeve 2 is connected to a container 21 for accommodating lubricating grease. A heater is installed in the container 21. The container 21 is connected to the insulation sleeve 2 through an oil pipe 22.

[0023] As a preferred embodiment, the two ends of the thermal insulation sleeve are respectively formed with end plates. The end plates seal the two ends of the thermal insulation sleeve. The two end plates are respectively provided with a discharge hole and a feed hole. An elastic sealing gasket is installed in the feed hole.

[0024] The insulation sleeve is used to contain liquid lubricating grease. When the wire rope passes through the insulation sleeve, it is immersed in the liquid lubricating grease, and then the liquid lubricating grease can easily enter the spiral cavity between two adjacent strands of the wire rope.

[0025] The temperature control sleeve 3 is used to cool the liquid lubricating grease coated on the outside of the steel wire rope, so that the lubricating grease can solidify quickly to coat the outside of the steel wire rope.

[0026] Specifically, the temperature control sleeve 3 has a front end and a rear end relative to each other. The insulation sleeve 2 is installed in the front end. A liquid injection channel 30 is formed in the tube wall of the temperature control sleeve 3. The liquid injection channel 30 is spiral. The liquid injection channel 30 is arranged along the length direction of the temperature control sleeve 3. Cooling liquid is contained in the liquid injection channel 30. One end of the liquid injection channel 30 is connected to a liquid storage tank through a liquid feeding pipe. The liquid storage tank contains cooling liquid. The other end of the liquid injection channel is connected to the liquid storage tank through a liquid return pipe. The liquid storage tank contains cooling liquid. A refrigerator is installed in the liquid storage tank to adjust the temperature of the cooling liquid in the liquid storage tank.

[0027] The shaping sleeve 4 is arranged at the rear end of the temperature control sleeve 3. The shaping sleeve 4 is coaxially arranged with the insulation sleeve 2 and the temperature control sleeve 3. The shaping sleeve 4 has a large diameter end and a small diameter end, and the large diameter end is aligned with the rear end. The size of the small diameter end is 1.05 to 1.10 times the diameter of the steel wire rope 6.

[0028] The inner diameter of the rear end of the temperature control sleeve 3 is 1.10 to 1.15 times the diameter of the steel wire rope 6 .

[0029] In this embodiment, the shaped sleeve is trumpet-shaped. The inner diameter of the shaped sleeve 4 gradually increases from one end of the shaped sleeve 4 away from the temperature-control sleeve 3 to the other end of the shaped sleeve 4 close to the temperature-control sleeve 3.

[0030] The receiving hopper 23 is arranged on the accommodating box 21. An electric heating network 5 is connected between the shaping sleeve 4 and the rear end. The electric heating network 5 is arranged above the receiving hopper 23.

[0031] The processing flow of the wire rope lubricating grease coating device of the utility model comprises the following steps:

[0032] The stranding machine twists the wire rope into wire rope;

[0033] One end of the steel wire rope passes through the feed hole, the discharge hole, the temperature control sleeve and the shaping sleeve in sequence and is wound on the drum.

[0034] The heater heats the lubricating grease in the containing box, so that the lubricating grease becomes liquid. The liquid lubricating grease is pumped into the insulation sleeve through the oil pump and the oil delivery pipe. When the steel wire rope enters the insulation sleeve, it is immersed in the hydraulic lubricating grease in the insulation sleeve. The steel wire rope fully coated with liquid lubricating grease enters the temperature control sleeve. The delivery pump in the liquid storage tank pumps the coolant into the injection channel through the delivery pipe, and reduces the temperature of the insulation sleeve through heat exchange, so that the external lubricating grease of the steel wire rope entering the temperature control sleeve is quickly solidified. The coolant is then transported to the liquid storage tank through the return pipe, and the temperature of the coolant is maintained under the action of the refrigerator. After the lubricating grease solidifies, the steel wire rope enters the trumpet-shaped fixed sleeve. The extrusion effect of the small-diameter end of the fixed sleeve tightly covers the lubricating grease on the outside of the steel wire rope to form a lubricating grease film layer. Excess lubricating grease is retained in the fixed sleeve. As the retention amount of lubricating grease in the shaped sleeve increases, it overflows from the outside of the large-diameter end of the shaped sleeve. After being heated by the heating net, it becomes liquid again and drips into the receiving hopper to replenish the insulation sleeve.

[0035] The utility model relates to a wire rope lubricating grease coating device, which immerses the wire rope in hydraulic lubricating grease so that the lubricating grease can also be poured into the spiral cavity of the wire rope, and then forms a dense, uniform and complete lubricating grease film layer on the outside of the wire rope through cooling of the temperature control sleeve and extrusion of the shaping sleeve, thereby improving the production and processing quality of the wire rope.

[0036] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.
