Description

.one

The invention relates to electrical engineering, in particular to a high voltage power line in compressed gas pipes, and serves to secure insulating washers to the tubular busbar.

A clamp is known for securing an insulating washer on a tubular tire, such as a transmission line located in a compressed gas pipe, containing a threaded ring on the inner surface.

A disadvantage of the known clamp is that its use requires a complicated and expensive technology for manufacturing a tubular tire of long length.

The purpose of the invention is to simplify the production technology of a tubular tire - is achieved by the fact that the clip is provided with an additional ring with two grooves and threads on the outer surface mating with the thread of the main ring, as well as two half rings, each with a radial protrusion located inside the half ring the shape of the hole in the tire and tail protrusion located along the generatrix; half-rings corresponding to the shape of the groove of the additional ring.

FIG. 1 shows the proposed in FIG. 2 - additional ring in two projections; in fig. 3 - semiring in two projections.

To secure the clamp, it is necessary to drill in the tubular tire with a drill or punch two opposing holes with a hand stamp. Holes can have any shape

(round, rectangular, square, etc.).

The clamp consists of a ring 1 with thread on

internal surface, additional

rings 2 and two half-rings 3. Ring 1 has

at the end of the groove under the rubber gasket.

The additional ring has an external thread, and at the end there is a groove in which two counter grooves 4 are made. Each half ring is provided with two protrusions, one of which, radial protrusion 5, has a round

the shape according to the hole in the tubular tire, is located radially and directed inside the half-ring, and the second, tail protrusion 6, is flat, located; it is perpendicular to the radal-shaped ledge 5 and directed along the generatrix of the half-ring.

When assembling, an additional ring is put on the pipe, two half-rings from opposite sides are laid with radial protrusions in the holes on the pipe, and tail projections into the grooves of the additional ring. The main ring is screwed on top of the additional ring, which secures the half-rings in their sockets and closes the elastic gasket between the ring and the insulating washer. Thanks to the clutch

3

the tails of the half-rings do not rotate the additional ring on the tubular tire, which facilitates the screwing of the rings. The radial protrusions of the half-rings securely fasten the ring on the tubular bus.

The clamp described has a smooth, even surface, is technologically easy to perform, does not require much effort to fasten, reliably secures the washer on the tubular bus, can be performed in field conditions, which facilitates installation and repair of the transmission line in the pipes.

Subject invention

A clamp for securing an insulating washer on a tubular tire, for example, a transmission line located in a compressed gas pipe, contains a threaded ring on the inner surface, distinguished by the fact that, in order to simplify the manufacturing technology of the tubular busbar, the clip is provided with an additional ring with two grooves and a thread on the outer surface matched with the thread of the main ring, as well as two half rings, each of which is made with

a radial protrusion located inside the half-ring, corresponding in shape to the hole in the tire, and a tail protrusion located along the generatrix of the half-ring, corresponding in shape to the groove of the additional

rings.
