Description

Device for aerial laying of fiber optic cable

The invention relates to technological equipment for aerial installation of fiber-optic cable (FOC).

A device is known for mounting a cable on a power line (1), including two reels for a cable, a stopper bracket for preventing rotation of the first reel when winding the cable, a traction element, two winding reset elements, etc.

A known unit for laying a wok on an overhead power line wire (2), comprising a cable laying mechanism, coupled to a coupling device by mechanical or manual towing devices, a wok guide device, a brake, a movable counterweight, a counterweight movement mechanism on the bar.

A device is known for winding a wok around an overhead wire of a power line (3), comprising a supporting element, a wok coil connected with a rotation drive, and a counterweight.

The disadvantages of the known devices (1-3) is the large weight and complexity of the design.

The objective of the utility model is to create a lightweight simple device in which the displacement of the center of gravity is negligible. The proposed device allows you to place a longer

 ., .. 2 segment of the wok and has a small range of rotation.

The specified technical result is achieved in that the device for aerial laying of fiber optic cable (FOC), containing a coil with FOC connected to the rotation drive, contains a second coil and a roller associated with the rotation drive, while the coils are mounted on the shaft with the possibility of joint rotation and are located symmetrically with respect to the carrier wire, the wok is wound on both coils, while the wok is transferred from one coil to another, and the roller is configured to maintain a specified wok tension.

In FIG. 1 shows a diagram of the proposed device. The device comprises a rotation drive 1, connected with coils 2 and 3, which are placed on the shaft 4 with the possibility of joint rotation, and a roller 5.

The wok is wound on both coils with the possibility of transition from one coil to another. Roller 5 serves to maintain the necessary tension. When unwinding from coils, the wok passes through the roller and wraps around the wire of the power line or technological torso. Moving

devices by wire can be carried out both in manual mode and with the help of a towing vehicle. The symmetrical arrangement of the coils relative to the carrier wire and the winding of the wok from both coils ensures that the center of gravity of the device is not displaced, which allows the device to be balanced without using a counterweight, which reduces weight and

the dimensions of the device and allows you to use the device for laying wok on low-voltage power lines, where thin wires are used and there is little distance between the wires. Weight reduction due to the absence of a counterweight allows winding a large wok length on coils.
