Description

Auxiliary support device for pole overhead ground wire and OPGW optical cable

technical field

The invention relates to the technical field of electric power construction auxiliary tools, in particular to an auxiliary supporting device for overhead ground wires of electric poles and OPGW optical cables.

Background technique

During the electric power construction process of overhead ground wire erection, operations such as setting out wires, connecting overhead ground wires, hanging wires, and tightening wires are required. The traditional erection method is to fix the wire pulley on each pole or iron tower, and then The overhead ground wires on the reel are pulled to each pole or iron tower in turn. After the overhead ground wires are pulled, the overhead ground wires on each pole or iron tower need to be hung and tightened to complete the overhead. For the erection of the ground wire, a guard wire will be wound on the overhead ground wire before the wire is tightened to protect the overhead ground wire. Since the overhead ground wires on both sides of the pay-off block are not supported, the overhead ground wire will sag downward under its own weight. In order to make the protection wire winding standard and fix the overhead ground wire convenient, an auxiliary person is required to move the pay-off block The support of the overhead ground wire on the side is in a horizontal state, and another operator will wind the protective wire on the horizontal overhead ground wire. When the protective wire on this side is wound, the assistant will change the position. Support the overhead ground wire on the other side of the pay-off block in a horizontal state, and then the operator will wind the wire protection on the overhead ground wire on this side. Also, when tightening the wire, auxiliary personnel are also required to support the overhead ground wire In the horizontal state, the overhead ground wire is fastened to the pole or iron tower through the clamp. The above-mentioned traditional overhead ground wire erection method has the following disadvantages: the weight of the overhead ground wire is heavy, and the required supporting force is large. Under high-altitude operations, the physical strength of the auxiliary personnel supporting the overhead ground wire is relatively large, and they are prone to fatigue very quickly, and the labor intensity is high. During the winding or fastening process of the protective wire, the overhead ground wire is always supported on the pay-off block, which occupies a large operating space. When winding the protective wire, the protective wire needs to pass through the pay-off The passing position of the overhead ground wire on the pulley, and the passing position of the overhead ground wire on the pay-off block is relatively narrow, which is not convenient for the winding operation of the guard wire. When tightening the overhead ground wire, it is necessary to remove the pay-off block while supporting the overhead ground wire. After taking off the pay-off block, the wire clamp can be fixed, because the fixed point of the wire clamp is the same as the fixed point on the pole or iron tower where the pay-off block is located, which increases the difficulty of operation.

The present invention is used on the electric pole in this way: after the overhead ground wire is pulled, first put the installation cap on the top of the electric pole, and by operating the lifting mechanism, the protruding ends of the left and right support arms are both swung downward Keep it away from the support pole, make the lifting hooks on both sides of the pole, until the lifting hooks on the support arm can hook the overhead ground wires on both sides of the pole, and then operate the lifting mechanism to make the extended end of the support arm Swing the support rod in the direction, move the overhead ground wire upwards for a certain distance until the overhead ground wire between the two lifting hooks is in a horizontal state, and the overhead ground wire is supported by the lifting hooks to maintain a horizontal state, and then put the ground wire on the pole Remove the wire pulley, and then carry out wire protection winding and wire tightening operations. After the overhead ground wire is tightened, operate the lifting mechanism to make the extending ends of the left and right support arms swing downward, and the lifting hook on the support arm Move downwards to separate the lifting hook from the overhead ground wire, then put away the present invention, and finally remove the present invention from the electric pole to complete the wire tightening operation on the single electric pole. After adopting the present invention, there is no pay-off block on the electric pole during the process of winding and tightening the protective wire, so that the operation space is large, the interference of the pay-off block on the operating position is avoided, the convenience of operation is improved, and the operation is ensured. It ensures that the winding and tightening of the protection wire can meet the specification requirements, and only one person can operate it, which reduces the support of the auxiliary personnel for the overhead ground wire, eliminates potential safety hazards, and reduces labor intensity and cost.

Due to the adoption of the above technical solution, the present invention has the following advantages: it supports the overhead ground wire to provide a large operating space for the installation of the overhead ground wire, and its structure is simple, easy to operate, reduces the number of workers, and eliminates the safety hazards and improve work efficiency.
