Abstract

The invention particularly provides an obstacle-crossing single cable fly cart for overhaul of an overhead transmission line. The obstacle-crossing single cable fly cart solves the problem that power supplying reliability is influenced due to the fact that when crossing an obstacle, an existing single cable fly cart has potential safety hazards and wastes time and force. The obstacle-crossing single cable fly cart for overhaul of the overhead transmission line comprises a single cable fly cart body, supporting rods are fixed to two pulley wheels at the upper end of the single cable fly cart body, an adjusting rod fixed to the two supporting rods is arranged at the top ends of the two supporting rods, a long-strip hole is formed in the middle of the adjusting rod, a vertically arranged screw penetrates into the long-strip hole, adjusting nuts located at the upper end face and the lower end face of the adjusting rods are screwed on the screw, a butting and pressing pulley frame is fixed to the lower end of the screw, and a butting and pressing pulley is arranged on the butting and pressing pulley frame. The obstacle-crossing single cable fly cart for overhaul of the overhead transmission line is reasonable and reliable in design, reduces labor strength of overhaul personnel while ensuring safety of the overhaul personnel, enables the operation process to be fast and labor-saving, effectively improves overhaul efficiency, ensures reliable performance of supplying power to an electric power line, and has the advantages of being simple in structure, convenient to process and low in cost.

Description

Obstacle detouring single line driving for maintenance of overhead transmission line
Technical field
The present invention relates to transmission line overhauling device, be specially a kind of maintenance of overhead transmission line obstacle detouring single line driving.
Background technology
At present, most 110KV and following transmission line single line metal guide ground wire are because overcurrent produces high temperature or year is oxidized for a long time, and the factor of outside destroy, can cause under normal circumstances lead wire and earth wire metallic object generation strand system, disconnected strand of wire and suspension foreign matter etc. to affect the normal safe operation of circuit.
Overwhelming majority defect all occurs in apart from the nearlyer lead wire and earth wire stockbridge damper of shaft tower front span central authorities, after defect occurs, have a power failure while processing general defect, adopt the manned driving outlet of single line processing, existing single line driving hanging wire enters behind scene owing to being subject to round and smooth wheel that limitation is set, carrying people runs into unloading after shake stockbridge damper of lead wire and earth wire installation at single line driving pulley, need will after self-contained safety rope adjustment, depart from single line driving, to self be fixed on safety rope, again single line driving is opened, single line driving is moved past to barrier (stockbridge damper) with hand, after single line driving is fixing, again depart from safety rope, displacement single line driving slides forward again, in operating process, personnel are in the time that disengaging driving is carried by safety rope, slightly depositing to sense greatly causes health whereabouts dangerous, there is potential safety hazard, and strengthened personnel's labour intensity, and extended the defect processing time simultaneously, the reliability of guaranteeing power circuit power supply is impacted.
Summary of the invention
The present invention exists potential safety hazard and wastes time and energy when solving existing single line driving across obstacle affects the problem of power supply reliability, and a kind of maintenance of overhead transmission line obstacle detouring single line driving is provided.
The present invention adopts following technical scheme to realize: maintenance of overhead transmission line obstacle detouring single line driving, comprise single line driving body, on two pulley yokes of single line driving body upper end, be all fixed with support bar, the top of two support bars is provided with the adjusting rod fixing with both, the middle part of adjusting rod has strip hole, in strip hole, be installed with the screw rod of vertical setting, on screw rod, be screwed with the adjusting nut that is positioned at adjusting rod upper and lower end face, screw rod lower end is fixed with jacking sliding wheel carrier, is provided with jacking sliding wheel on jacking sliding wheel carrier.
When across obstacle, first jacking sliding wheel is placed in to pulley one side of preparing barrier, regulate jacking sliding wheel to contacting with wire simultaneously, now, the adjusting nut of loosening adjusting rod upside, the adjusting nut of recycling instrument rotation adjusting rod downside, under the effect of lever principle, the pulley of preparing barrier departs from wire, jacking sliding wheel replaces the pulley of preparing barrier to move forward, after the pulley of driving front side clears the jumps, single line driving two pulley contact wire loads during by adjustment adjusting nut, jacking sliding wheel unloads after power and moves to and treated barrier driving pulley one side, be operated to equally and treated that barrier driving pulley cleared the jumps, while having overcome existing single line driving across obstacle, there is potential safety hazard and waste time and energy and affect the problem of power supply reliability.
Reasonable in design of the present invention is reliable, when ensureing maintainer's safety, has alleviated maintainer's labour intensity, operating process convenient power-saving, effectively improve overhaul efficiency, guaranteed the unfailing performance to power circuit power supply, had advantages of simple in structure, easy to process and cost is low.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1-single line driving body, 2-support bar, 3-adjusting rod, 4-strip hole, 5-screw rod, 6-adjusting nut, 7-top pinch roller balladeur train, 8-jacking sliding wheel.
Embodiment
Obstacle detouring single line driving for maintenance of overhead transmission line, comprise single line driving body 1, on two pulley yokes of single line driving body 1 upper end, be all fixed with support bar 2, the top of two support bars 2 is provided with the adjusting rod fixing with both 3, the middle part of adjusting rod 3 has strip hole 4, is installed with the screw rod 5 of vertical setting in strip hole 4, is screwed with the adjusting nut 6 that is positioned at adjusting rod 3 upper and lower end faces on screw rod 5, screw rod 5 lower ends are fixed with jacking sliding wheel carrier 7, are provided with jacking sliding wheel 8 on jacking sliding wheel carrier 7.
In specific implementation process, before installation, need test the presentation quality of each pad and working stress, and through in-site modeling operation, to meet simple and efficient job requirement.
