Unwinding device for measuring lengths of electric wires and optical cables

Abstract

The invention discloses an unwinding device for measuring the lengths of electric wires and optical cables. The unwinding device comprises a base, a third roller, a fourth roller and a belt; a bracketis welded on the base, and is fixedly connected with a first optical shaft; the first optical shaft is rotationally connected with a cable roller; a transition device is mounted on the base on the right side of the cable roller; bearing columns are mounted on two sides of the base, and are fixedly connected with a fourth optical shaft; the fourth optical shaft is connected with the third roller through a bearing; and the bearing column under the fourth optical shaft is connected with a fifth optical shaft through a bearing. The unwinding device for measuring the lengths of the electric wiresand the optical cables can realize automatic winding to save a lot of manpower, and can display the lengths of unwound cables; through the transition device, the cables cannot be twisted in the unwinding process; and the bearing columns are provided, so that the device can adapt to the cables with different diameters, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a pay-off device for measuring the length of electric wires and optical cables. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. With the development of China's electric power industry, data communication industry, and urban rail transit With the continuous expansion of industry, automobile industry, shipbuilding and other industries, the demand for wires and cables will also grow rapidly, and the number of electric power projects will gradually increase. Common electric construction workers on the roadside will use the wound coils to release the wires. [0003] The current traditional cable pay-off dev...
