Description

Cross spanning line pay-off device

Technical Field

The invention relates to cross spanning line operation equipment, in particular to a cross spanning line pay-off device.

Background

The cross-line routing refers to the operation of power transmitted from one side to the other side of the cross-line via the top of the lower layer of lines. Because lower floor's circuit is electrified, in order to avoid strideing across the circuit and contacting lower floor's circuit, guarantee to stride across the safety of circuit unwrapping wire, when strideing across the circuit unwrapping wire, need have a power failure to lower floor's circuit, the power failure operation mode brings inconvenience for the user, brings serious economic loss for the enterprise. At present, in order to pay off a crossing line under a charged condition, an operator erects support frames on roads on two sides of a lower line, and hangs a protective net above the lower line between the support frames on the two sides, so as to prevent the crossing line from contacting the lower line. The crossing line paying-off structure is heavy, large in installation difficulty, time-consuming and labor-consuming, and due to the fact that the support frame is erected on the road in the crossing paying-off mode, normal running of pedestrians and vehicles on the road is affected by the erected support frame, and traffic passing is seriously affected.

Disclosure of Invention

The invention aims to solve the technical problems and provides a cross-over line pay-off device which is light in structure, convenient to install, time-saving and labor-saving, is directly installed on a lower-layer power transmission line, does not occupy roads, and is convenient for pedestrians and vehicles to normally run so that traffic can normally pass.

The technical solution of the invention is as follows:

cross and stride across circuit pay-off, including insulating support body, its special character lies in: two groups of wire fixing mechanisms which are arranged left and right are arranged on the lower portion of the insulating frame body, the same group of wire fixing mechanisms are arranged front and back, three groups of wire releasing mechanisms which are arranged front and back are arranged on the upper portion of the insulating frame body, the same group of wire releasing mechanisms are arranged left and right, and each wire releasing mechanism is composed of an upper vertical supporting rod, a wire releasing wheel group which is arranged on the upper supporting rod from top to bottom and a motor which drives the wire releasing wheel group to rotate.

Preferably, the wire fixing mechanism is composed of a vertical lower support rod and a wire clamp installed at the lower part of the lower support rod.

Further preferably, the height of the pay-off mechanism is 600 and 800 mm.

Further preferably, the distance between the two adjacent pay-off mechanisms is 400-600 mm.

Further preferably, the distance between the wire fixing mechanism and the wire releasing mechanism on the same side is 1000-1200 mm.

Further preferably, the lower part of the insulating frame body is positioned between the two groups of wire fixing mechanisms, the hooks are hooked on the lower layer of the power transmission line, and the stability of the installation structure of the insulating frame body is improved.

Further preferably, a tension spring is connected between the insulating frame body and the hook, so that the hook is convenient to hook on the basis of ensuring the structural strength of the hook.

Further preferably, a battery is mounted on each upper support rod, the battery being electrically connected to the corresponding electrode.

The invention has the beneficial effects that:

this alternately stridees across circuit pay-off structure is light, and the installation of being convenient for, labour saving and time saving, and its direct mount establishes insulating support on lower floor's power transmission line between strideing across circuit and lower floor's circuit, does not occupy the road, and the pedestrian of being convenient for and vehicle normally travel guarantee that the traffic is normally current.
