Wire unwinding device for electric construction

Abstract

The invention discloses a wire unwinding device for electric construction. The device comprises a mode adjusting button, a hub, a mechanical chain, a damper device, a wire unwinding disc, a limiting plate, a connecting rod, a metal bracket, a base and a controller; and the damper device is provided with a linkage trigger device, an ascending adjusting device, a turbine driving device, a transmission device, a friction speed reducing device, a movable adjusting device, a trigger startup device and a metal edge frame. The device has the following beneficial effects: the motion resistance can beprovided through the added damper device; and the wire unwinding tension is preferably controlled through a motion energy reducing device, and the wire unwinding tension of leads is always stabilizedat a critical value between deformation and no deformation, so that ultrafine leads are preferably protected, wires can be arranged at a wiring end more stably, the conditions of wire breakage and flight are reduced, the long-time ordered construction work is facilitated, and the construction period is shortened.

Description

technical field [0001] The invention is a pay-off device for electric power construction, which belongs to the field of pay-off devices. Background technique [0002] The pay-off device is divided into ground cable pulley, cable pulley, sky pulley, nylon pulley, cable wire pay-off pulley, large-diameter pay-off pulley, double-purpose pay-off pulley for hanging, ground wire pay-off pulley, and lifting pulley. It plays a protective role when laying cable conductors, saving time and effort. The use of ground cable pulleys is used for cable extension and changing directions to protect cables from friction. It is a kind of pay-off device for electric power construction in the current technology. The pay-off device still relies on the guide wheel or by gravity or tension to pay off the wire. There is not much problem of wire breakage when used on wires with thick wire diameter or high tension resistance. However, with the progress of ultra-thin wire , the tensile strength of the ...

[0002] The pay-off device is divided into ground cable pulley, cable pulley, sky pulley, nylon pulley, cable wire pay-off pulley, large-diameter pay-off pulley, double-purpose pay-off pulley for hanging, ground wire pay-off pulley, and lifting pulley. It plays a protective role when laying cable conductors, saving time and effort. The use of ground cable pulleys is used for cable extension and changing directions to protect cables from friction. It is a kind of pay-off device for electric power construction in the current technology. The pay-off device still relies on the guide wheel or by gravity or tension to pay off the wire. There is not much problem of wire breakage when used on wires with thick wire diameter or high tension resistance. However, with the progress of ultra-thin wire , the tensile strength of the ultra-fine wire itself is very small, and the pay-off device meets the requirements for unwinding the ultra-thin wire. If the same method is used to pay off the wire, the power wire will be broken and damaged.
