Description

one

The invention is related to power engineering and to be used to protect wires and cables of overhead transmission lines from corrosion by lubricating them.

A device for lubricating wires and cables is known, which contains a trolley with rollers and a reservoir with lubricant within which the piston is moved to feed it || 1. 1 The residuals of this device consist in uneven coating of the wire with lubricant and the possibility of lubricant leakage during operation.

The closest in technical essence and the achieved result to the invention is a device for lubricating wires and cables, comprising a housing with a cap, filled with grease, equipped with rollers serving to move along the wire, and a calibration element mounted in the housing 2.

However, this device cannot pass the connector when it is moving along a power line wire.

The purpose of the invention is to ensure the passage of the device through a wire-mounted connector and extend the range of lubricated wires.

This goal is achieved by the fact that in a device for lubricating wires and cables, comprising a housing with a lid, filled with lubricant, equipped with rollers that serve to move along a wire, and a buckling element, the new element is that it is fitted with spring-loaded pairs on horizontal axes. the curtains made of sheet material, bent at a certain angle, provided with clamping springs, each of which is connected at one end to the corresponding curtain, and the other end is fixed to the housing.

Figure 1 shows the proposed device, a General view; figure 2 is the same, side view; on fig.Z - section along aa in figure 2; Fig. 4 is a diagram of the movements of the shutters during the passage of the connector device.

The device is made in the form of a housing 1 with a cover 2 in which the lubricant is placed. On the wire (cable) 3, the device is moved by the rollers 4, connected through pciMy 5 with the housing 1.

A hinged box 6 is attached to the bottom of the housing 1, on which the counterweight 7 is suspended. In the housing 1 and

Box 6, respectively, are installed in pairs on horizontal axes x 3 upper curtains 9 and lower curtains 10 ,. r pressed by springs of torsion 11. In the shutters there are replaceable calibration jaws 12.

The device works in the following way.

Depending on the diameter of the lubricated wire (cable), the necessary jaws 12 are selected from the kit. The box 6 is opened and the device is installed on the wire 3, then the box 6 is locked onto the housing 1, When the cover 2 is open, the housing 1 is filled with grease and the device 13 t net by wire 3.

Lubrication is made through the gaps of the jaws 12. When the connector 14, which is installed on the wire, passes through, the shutters 9, 10 abut against it, turn relative to their axes 8, the connector passes, After the connector passes through, the shutters close
