Description

Technical Field

[0001] The utility model relates to the technical field of stranded wire oiling devices, in particular to an anti-corrosion oiling device for steel core aluminum stranded wires. Background Art

[0002] Steel-core aluminum stranded wire is made of aluminum wire and steel wire, and is suitable for overhead power transmission lines. Anti-corrosion steel-core aluminum stranded wire has the characteristics of simple structure, convenient installation and maintenance, large transmission capacity, and is conducive to laying across rivers and valleys and other special geographical conditions. In order to prevent corrosion of steel-core aluminum stranded wire, an oiling device is required to apply anti-corrosion grease on the surface of the steel-core aluminum stranded wire. The existing oiling device still has certain defects when used, such as;

[0003] Most of the existing oiling devices use a simple grease recovery box. A circular hole is cut on both sides of the oil box along the radial direction of the twisted wire core for the coated wire core to pass through. However, due to its viscosity, the grease will be pulled by the wire core to create gaps, resulting in the amount of grease applied being sometimes more and sometimes less. At the same time, a large amount of grease will be scattered. When the grease is exhausted, if grease is not added in time, the grease will be unevenly applied and the amount of grease cannot be evenly controlled. Utility Model Content

[0022] See also Figure 1-Figure 3 The utility model provides a technical solution: a steel core aluminum stranded wire anti-corrosion oiling device, comprising: a grease barrel 1, a grease pump 2, an oil extraction pipe 3 and an auxiliary oil tank 4;

[0023] A liposuction pump 2 is connected to the top of the grease barrel 1 by bolts, and an oil suction pipe 3 is connected to one side of the liposuction pump 2, and an auxiliary oil tank 4 is connected to one side of the oil suction pipe 3; an electric valve 5 is connected to one side of the auxiliary oil tank 4, and a main oil tank 6 is connected to one side of the electric valve 5. Oil control mechanisms 7 are provided in the auxiliary oil tank 4 and the main oil tank 6. An opening mold 8 is connected to one side of the auxiliary oil tank 4 and the main oil tank 6, and a polyurethane pad 9 is provided in the opening mold 8. A mold fastening nut 10 is abutted on one side of the polyurethane pad 9, and the mold fastening nut 10 is threadedly connected to one side of the opening mold 8. A steel-core aluminum stranded wire body 11 is penetrated through the auxiliary oil tank 4, the main oil tank 6, the opening mold 8, the polyurethane pad 9 and the mold fastening nut 10.

[0024] During specific implementation, one side of the auxiliary fuel tank 4 and the main fuel tank 6 are connected to the open mold 8, which is used to pass the steel core aluminum stranded wire body 11 into the auxiliary fuel tank 4 and the main fuel tank 6 and apply grease. The polyurethane pad 9 can be selected with a suitable inner diameter according to the diameter of the steel core aluminum stranded wire body 11, and the excess grease can be scraped off to prevent excessive grease from dripping. The mold fastens the nut 10 and the open mold 8 to squeeze the polyurethane pad 9 between the two.

[0025] See also Figure 1 and Figure 3It can be seen that the oil control mechanism 7 includes: a cylinder 701, a buoyancy steel plate 702, a lower magnetic limit 703, an upper magnetic limit 704, an air source regulating valve 705, a solenoid valve 706, an air pump 707 and a controller 708. The cylinder 701 is connected to the upper part of the inner wall of the auxiliary oil tank 4 and the main oil tank 6. The bottom of the cylinder 701 is connected to the buoyancy steel plate 702. One side of the cylinder 701 is connected to the lower magnetic limit 703 at the bottom, and one side of the cylinder 701 is connected to the upper magnetic limit 704 at the top. The side of the cylinder 701 away from the lower magnetic limit 703 and the upper magnetic limit 704 is connected to the air source regulating valve 705, one side of the air source regulating valve 705 is connected to the solenoid valve 706, one side of the solenoid valve 706 is connected to the air pump 707, and the solenoid valve 706 and the electric valve 5 are electrically connected to the controller 708.

[0026] During specific implementation, the air pump 707 is installed on the barrel cover of the grease barrel 1, which is convenient for replacing the grease barrel 1 later. The air pump 707 is started to adjust the air source regulating valve 705 to adjust the downward pressure of the cylinder 701, the electric valve 5 is opened and the liposuction pump 2 is started to extract the grease in the grease barrel 1 and send it into the auxiliary oil tank 4 and the main oil tank 6 from the oil extraction pipe 3. The grease floats the buoyancy steel plate 702. After shortening the cylinder 701 to trigger the upper magnetic limit 704, the grease in the auxiliary oil tank 4 and the main oil tank 6 has been filled. The controller 708 closes the liposuction pump 2 and the electric valve 5, and then opens the solenoid valve 706 connected to the main oil tank 6, inflates the cylinder 701 to squeeze the buoyancy steel plate 702, and when the steel-core aluminum stranded wire body 11 is moving, when the grease is applied to the steel-core aluminum stranded wire body 11, the buoyancy steel plate 702 squeezes and fills the gaps in the grease. When applying grease, the grease in the main oil tank 6 is continuously reduced, and the buoyancy steel plate 702 moves downward with the grease liquid level, driving the cylinder 701 to extend and trigger the lower magnetic limit 703. Then the grease in the main oil tank 6 has been exhausted, and the solenoid valve 706 connected to the main oil tank 6 is closed. The controller 708 starts the solenoid valve 706 connected to the auxiliary oil tank 4 to push the grease to be applied to the steel-core aluminum stranded wire body 11, and opens the electric valve 5 to start the grease pump 2 to add grease to the main oil tank 6. After the grease in the main oil tank 6 is filled, the electric valve 5 is closed. After the grease in the auxiliary oil tank 4 is used up, the solenoid valve 706 connected to the main oil tank 6 is started again, and the solenoid valve 706 connected to the auxiliary oil tank 4 is closed, and grease is added to the auxiliary oil tank 4. The cycle is switched continuously to keep the steel-core aluminum stranded wire body 11 uninterrupted when applying grease.

[0027] In summary, when using the anti-corrosion oiling device for steel core aluminum stranded wire, first, install the grease barrel 1 on the barrel cover at the bottom of the grease pump 2, connect the solenoid valve 706 with the air pump 707, insert the steel core aluminum stranded wire body 11 into the main oil tank 6 and the auxiliary oil tank 4, and pass it through the opening mold 8, select the polyurethane pad 9 according to the diameter of the steel core aluminum stranded wire body 11, and then sleeve the polyurethane pad 9 on the steel core aluminum stranded wire body 11 and install it in the opening mold 8, open the electric valve 5 and start the grease pump 2, and send the grease in the grease barrel 1 into the auxiliary oil tank 4. In the box 4 and the main oil tank 6, when the steel-core aluminum stranded wire body 11 is pulled, grease is applied to the steel-core aluminum stranded wire body 11, and the polyurethane pad 9 scrapes off excess grease to prevent dripping. After the grease in the main oil tank 6 is used up, the auxiliary oil tank 4 applies grease to the steel-core aluminum stranded wire body 11, and grease is added to the main oil tank 6. After the grease in the auxiliary oil tank 4 is used up, the main oil tank 6 is used to apply grease to the steel-core aluminum stranded wire body 11, and the switching is continuously circulated.
