Description

Technical Field

[0001] The utility model relates to the technical field of composite insulator rods, in particular to a large-diameter insulator and a mandrel one-time forming device. Background Technique

[0002] The composite insulator rod is composed of an umbrella sleeve, a mandrel and fittings at both ends. For products of 110 kV and below, grading rings are not equipped. For products of 220 kV and above, 1 - 2 grading rings are equipped, or grading rings can also be equipped according to user requirements.

[0003] The special coating is one of the important steps for treating the surface of the insulator rod, which can effectively enhance the voltage resistance and protection of the insulator rod, and resist the influence brought by harsh natural environments and human factors. Generally, the components of the special coating include epoxy resin, silicone rubber, fluoride, etc., which have excellent chemical stability and insulation performance and can provide reliable protection for the power system.

[0004] However, at the present stage, the special coating is completed by the stamping and wrapping method. Although this method can wrap the composite insulator rod, it cannot achieve dense wrapping. There will be a certain gap between the coating and the composite insulator rod. After a long time, water will accumulate in the gap, resulting in a reduced service life and possibly circuit failures. Summary of the Invention

[0027] Specifically, the lifting structure includes: a lifting frame 5, two lifting hydraulic cylinders 6, two lifting ropes 7 and two lifting fixing rings 8; the lifting frame 5 is installed on the upper wall surface of the bottom plate 1, the two lifting hydraulic cylinders 6 are respectively installed on the lower wall surface of the lifting frame 5, one ends of the two lifting ropes 7 are respectively installed on the lower wall surfaces of the two lifting hydraulic cylinders 6, and the two lifting fixing rings 8 are respectively installed on the other ends of the two lifting ropes 7. The lifting structure can drive the insulator and the mandrel to lift, so that the insulator and the mandrel can be immersed in the coating material multiple times, ensuring that the outside of the insulator and the mandrel can be completely wrapped by the coating.

[0028] Specifically, the rotational power structure includes: a power motor 9, a magnetic chuck 10 and an iron chuck 11; the power motor 9 is installed on the upper wall surface of the bottom plate 1, the magnetic chuck 10 is installed on the driving end of the power motor 9, and the iron chuck 11 is magnetically connected to the magnetic chuck 10. The hot air structure includes: a hot air hopper 12 and a hot air pipe 13; the hot air hopper 12 is installed on the upper wall surface of the bottom plate 1, one end of the hot air pipe 13 is installed at the tail of the hot air hopper 12. The rotational power structure can drive the insulator and the mandrel to rotate, and under the action of the hot air structure, the coating material can be attached to the outside of the insulator and the mandrel.

[0029] Working principle: When using the present utility model, first, an external AC power supply is connected to the present utility model to provide energy for the electrical appliances in the present utility model. Then, the operator installs the mandrel with large-diameter insulators inside the two lifting fixing rings 8 through bearings, and fixes the iron suction cup 11 at one end of the mandrel. Then, the operator connects the external hot air source and the hot air pipe 13, connects the coating raw material pipeline to be coated and the feeding pipe 14, and connects the discharging pipe 15 to the waste container. At this time, the preparation for one-time forming is completed. First, the magnetic suction cup 10 is in a demagnetized state. Then, the two lifting hydraulic cylinders 6 extend, driving the two lifting ropes 7 and the two lifting fixing rings 8 to descend, that is, making the mandrel with large-diameter insulators descend until the mandrel with large-diameter insulators is completely immersed in the coating container 3 filled with coating raw materials. At this time, the large-diameter insulators and the outside of the mandrel are wrapped by the coating raw materials. Then, the two lifting hydraulic cylinders 6 contract, driving the two lifting ropes 7 and the two lifting fixing rings 8 to rise, that is, making the mandrel with large-diameter insulators rise until the mandrel with large-diameter insulators completely disengages from the coating container 3 filled with coating raw materials, and making the iron suction cup 11 and the magnetic suction cup 10 in a coaxial state. Then, the magnetic suction cup 10 is started, and the magnetic suction cup 10 and the iron suction cup 11 are attached. Next, the power motor 9 is started, and the rotation of the power motor 9 drives the magnetic suction cup 10 and the iron suction cup 11 to rotate. The iron suction cup 11 drives the mandrel with large-diameter insulators to rotate. And at this time, the external hot air blows towards the large-diameter insulators and the mandrel through the hot air pipe 13 and the hot air hopper 12, evaporating the moisture in the coating material outside the large-diameter insulators and the mandrel, and making the coating material adhere to the outside of the large-diameter insulators and the mandrel. After repeating the above actions several times until the coating reaches the standard, the work of one-time forming is completed.
