Abstract
The utility model discloses an overhead line dewinder, which comprises a support. The support consists of two vertical support rods and a horizontal support rod for connecting the two vertical support rods integrally; a carrier roller shaft is mounted between the two vertical support rods positioned above the horizontal support rod; a lead carrier roller is rotatably connected onto the carrier roller shaft; bolt holes are arranged on the horizontal support rod; a line locking device is mounted between the two vertical support rods positioned above the lead carrier roller; and the line locking device includes bolts and nuts, wherein the bolts are mounted on the two vertical support rods in a penetrating manner, and the nuts are connected onto the bolts in a threaded manner. When the overhead line dewinder is used for dewinding an overhead line, a line is not required to be manually carried to the upper end of a porcelain insulator from the lower side of a cross arm by leaning, labor is saved, efficiency is improved, the line cannot fall off, and the overhead line dewinder prevents the lead from injuring pedestrians or inclining an electrical pole, and is high in safety performance. As the efficiency is improved, outage time is shortened, project duration is advanced, operating safety and reliability of power grids are improved, and power supply reliability is enhanced.
Description
Technical field
The utility model relates to a kind of power engineering facility, specifically is a kind of overhead transmission line wire dispenser.
Background technology
Because town road transformation in recent years, industry expands engineering and increases, and load increases relatively, and current carrying capacity of conductor does not satisfy growing load, according to designing requirement, overhead wire is replaced by JKLGY-240 insulated conductor.The wire dispenser that uses in restringing at present is a hook block, use hook block to have following problem: 1, efficient is low: the present hook block unwrapping wire that uses, during unwrapping wire, need two people that insulated conductor is shouldered to the porcelain vase top, increased artificial, this just needs more safety prevention measure, and the growth of maintenance engineering time, causes efficient to reduce.2, fail safe is low: use original hook block unwrapping wire, need manually below cross-arm, to stretch forward lead is shouldered to the porcelain vase upper end, JKLGY-240 insulated conductor, Heavy Weight, one people can't shoulder lead to the porcelain vase upper end, causes wire dropping easily, is crossing over the highway section, wire dropping may be taken out and hinder the pedestrian, perhaps causes electric pole to tilt.
The utility model content
The technical problems to be solved in the utility model provides a kind of high efficiency, overhead transmission line wire dispenser that security performance is high.
For addressing the above problem, the overhead transmission line wire dispenser that is provided comprises support, its design feature is: support is formed by two perpendicular poles with the cross support arm that two perpendicular poles are connected as a single entity, between the perpendicular pole of two above the cross support arm, roller carrier shaft is housed, be rotatably connected to the lead carrying roller on the roller carrier shaft, cross support arm is provided with bolt hole.
After adopting said structure, when using the utility model to carry out the overhead transmission line unwrapping wire, by bolt passing through bolt hole the utility model is fixed on the cross-arm top, insulated conductor is positioned on the lead carrying roller, the lead carrying roller that rotates helps carrying out unwrapping wire, thereby no longer need manually below cross-arm, to stretch forward lead is shouldered to porcelain vase upper end, saved artificial, improved efficient, and insulated conductor is positioned at cross-arm top (the cross-arm both sides are provided with porcelain vase) all the time, lead can not come off, the phenomenon of having avoided lead to take out hindering the pedestrian or having caused electric pole to tilt, security performance height.Because efficient has improved, thereby has reduced interruption duration, has shifted to an earlier date the duration of a project, has improved power network safety operation, has strengthened power supply reliability, created benefit for company and society.
As improvement of the present utility model, between the perpendicular pole of two above the lead carrying roller, the lead locking device is housed, can prevent effectively that insulated conductor from upspringing and break away from the lead carrying roller.
Described lead locking device is to be installed on the bolt on the two perpendicular poles and to be screwed onto nut on the bolt.
As further improvement of the utility model, on the bolt between the two perpendicular poles, sleeve is housed, lead is upspring when bumping to bolt, and the screw thread on the bolt can damage insulated conductor, and insulated conductor can be effectively protected in the setting of sleeve.
As further improvement of the utility model, owing to have the gap between the end face of lead carrying roller and the medial surface of perpendicular pole, for preventing that insulated conductor is stuck in the gap, the anti-sticking baffle plate all is equipped with in the inboard of two perpendicular poles above the lead carrying roller, and baffle plate can stop insulated conductor to enter this gap.
As further improvement of the utility model, the anti-plate of stretching of turning round is installed down on the support, be installed in cross support arm on the cross-arm after, the anti-interior facade of turning round plate is attached on the cross-arm, the utility model twists in the time of can effectively preventing unwrapping wire.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is along the cutaway view of A-A line among Fig. 1.
Embodiment
Overhead transmission line wire dispenser as depicted in figs. 1 and 2, it comprises support 1, support 1 is formed by two perpendicular poles 11 with the cross support arm 12 that two perpendicular poles 11 are connected as a single entity, the both ends of cross support arm 12 are connected the middle and lower part or the bottom of two perpendicular poles 11 respectively, between the perpendicular pole 11 of two above the cross support arm 12, roller carrier shaft 3 is housed, be rotatably connected to lead carrying roller 2 by bearing on the roller carrier shaft 3, cross support arm 12 is provided with bolt hole 6, when the utility model is installed, be installed in the bolt hole 6 and be fixed on the cross-arm that porcelain vase is housed by bolt, be convenient working, bolt hole 6 can vertically be provided with, and promptly the bottom of cross support arm 12 is positioned on the cross-arm.Between the perpendicular pole 11 of two above the lead carrying roller 2, the lead locking device is housed, this lead locking device is to be installed on the bolt 8 on the two perpendicular poles 11 and to be screwed onto nut 9 on the bolt 8, and the axle center of bolt 8 is approximately 10cm for best from the height of lead carrying roller 2; On 8 sections on the bolt between the two perpendicular poles 11, sleeve 7 is housed.For preventing that insulated conductor is stuck between lead carrying roller 2 and the perpendicular pole 11, the anti-sticking baffle plate 5 that stretches out in opposite directions all is equipped with in the inboard of two perpendicular poles 11 above lead carrying roller 2, anti-sticking baffle plate 5 can also can be vertical bar shape plate for arc, be vertical bar shape plate in this embodiment, the height of anti-sticking baffle plate 5 from lead carrying roller 2 axle center is about 4cm for best.When the end of cross support arm 12 is packed in the bottom of perpendicular pole 11, be symmetrically installed with the anti-plate of stretching under two 4 of turning round on the lower surface of cross support arm 12, after being installed in the utility model on the cross-arm, anti-the turning round on the side that plate 4 can be fitted in cross-arm of stretching down, thus the utility model is distorted when preventing unwrapping wire.
