SU20173A1 - Device for cleaning pin insulators - Google Patents

Description

The proposed device for cleaning pin insulators consists of a gear, Hfecyigeft brushes for cleaning the internal and external surfaces of the insulator. This gear can rotate around a sleeve worn on an insulator pin for longer than,. Place the device on the insulator pin and insert the inner brushes into the insulator cavity. The sleeve, gear and base of the device are provided with a cutout corresponding to the diameter of the pin.

In the drawing, FIG. 1 schematically shows a top view of the device; FIG. 2 is a section along the line AB in FIG. 1.

. The sleeve b of the device is fixed on the basis of a and And covers the insulator pin u. A washer was fixedly fixed on the hub b, serving as a guide gear g, a carrying brush for cleaning the insulator from dust. A washer g is screwed to gear r from the bottom, holding the gear while rotating, in a position concentric with the sleeve. The gear wheel carries brushes on it: q in such an amount that for each inter-working space of the insulator there are two brushes, Cleansing, respectively, the near and farthest surfaces from the pin. In addition, the gear wheel carries a w

outer surface of the insulator. For inserting the inner brushes into. the cavity of the insulator and the girth of the sleeve b its pin, gear, sleeve 6, washers w and d are provided with a cut-out corresponding to the diameter of the pin, and the sleeve b is also shoulder to install the brushes in a position relative to the insulator. When the device is in operation, gear g is rotated by hand by means of a handle c, a bevel gear gear m, e, a cylindrical gear gear w, e, f. Continuous rotation of the gear g around the pin of the insulator, looking at the presence of a slot, is achieved by the fact that it is driven into rotation not by one but by two gears e and dB coupled to it and removed so that their points of adhesion are circumferential distance greater than the width of the slot, i.e. such that at each moment at least one of these gears is in engagement with gear r,

The device is enclosed in an enclosure h, fastened on the base of a and is applied with the help of a handle p on the pin of the insulator to be cleaned. After installing the instrument, cleaning is done by turning the knob.

 - Subject of the patent.

1. A device for cleaning pin insulators, characterized in that it consists of a sleeve 6, which is guided by a covering pin and a washer connected to it, and gear g, which can rotate around the sleeve 6 and support the brushes on it, t, such a number so that for each inter-working space of the insulator there are two brushes, cleaning, respectively, the near and farthest surface of this space, and, moreover, a brush for cleaning the outer surface of the insulator, with the aim of allowing the contribution of Vani internal brushes in strip insulator and reach its pin bushing i, b sleeve, washer m and provided with gear-cut corresponding to the pin diameter.

2. The form of the device described in p. 1, characterized in that, in order to allow continuous rotation of the gear g around the crankbag, in spite of the gap in it, gears coupled to it and dB are used to directly drive the gear g. , so placed one relative to another around the circumference of gear g, so that at each moment at least one of these gears is in engagement with gear g.
