Abstract
The utility model relates to a tensioning pay-off pulley for strain steel tube poles, which mainly resolves problems that a spatial distance between a conducting wire and a strain insulator string hanging point is over large to cause failure in hanging the strain insulator string. The tensioning pay-off pulley is characterized in that a circular rotary base (3) is arranged at the center of a pulley base, the upper portion of the rotary base (3) is fixed with two opposite baffles (5), a pulley shaft (7) is fixedly connected between the baffles (5) and provided with a pulley (1), two opposite arc-shaped ducts (6) are arranged at the peripheral edge of the rotary base (3), and the rotary base (3) is fixed with the pulley base (4) via screws inside the arc-shaped ducts (6). The tensioning pay-off pulley for strain steel tube poles has the advantages that a spatial distance between a conducting wire and a strain insulator string hanging point is small, and the strain insulator string can be hung easily when tightening the wire.
Description
Technical field:
The utility model relates to the coaster that a kind of trolley wire uses, the tight releasing pulley of particularly a kind of strain insulator steel pipe pole.
Background technology:
Along with increasing sharply of power load, need go down town circuit or netting twine road, original city carried out capacity-increasing transformation of newly-built high pressure because steel pipe pole is simple in structure, stressed evenly, easy construction, floor space is little, in the city network transformation process, is adopted widely.In the tight unwrapping wire process, particularly at independent shelves unwrapping wire, because the insulator string hanging point of strain insulator steel pipe pole cross-arm and strain insulator iron tower and strain insulator cement pole is different.Construction Work tool in the past and method can not be finished the construction of steel pipe pole.Iron tower, cement pole are when tight unwrapping wire, coaster hangs on the cross-arm head, the height of lead is substantially at sustained height when strain insulator string hanging point and coaster unwrapping wire, so be easy to strain insulator string is hung up, if the cross-arm of strain insulator steel pipe pole is pressed the tight unwrapping wire of original method as shown in Figure 5, the strain insulator string hanging point prints during apart from stringing a little the difference in height of 55cm, be not easy to workmen's operation on the bar, cause the stringing that accurately to print, even and accurately print also and not reach the standard grade because the reason of difference in height is hung.According to " sending electric professional code compilation " regulation, when the stringing span is 200～300 meters, crosses drawing length and should not surpass 0.5 ‰ of span, promptly be no more than 15cm, so in this case, even adopted the method for traction, strain insulator string is not hung equally.Moreover utilize conventional method to carry out the hanging wire construction, lead is deviate from pulley easily, is stuck with coaster, cause lead impaired serious, this root lead must be scrapped when this thing happens, and it is also very difficult to remove the lead that is stuck in the coaster, has great potential safety hazard.
The utility model content:
Technical problem to be solved in the utility model is to overcome lead that exists in the background technology and the problem that strain insulator string hanging point space length is excessive thereby strain insulator string is not hung, and provide a kind of strain insulator steel pipe pole tight releasing pulley, the characteristics that the tight releasing pulley of this strain insulator steel pipe pole has lead and strain insulator string hanging point space length is little, strain insulator string hangs up easily during stringing.
The invention for solving the technical problem can reach by following technical solution: the tight releasing pulley of this strain insulator steel pipe pole comprises pulley, the coaster base, coaster base center is equipped with circular rotating basis, two relative baffle plates are fixed on rotating basis top, affixed pulley spindle between two baffle plates, pulley is housed on the pulley spindle, and there are two relative arc ducts at the circumferential edges place of rotating basis, and rotating basis and coaster base are fixed by arc duct inner bolt.
Described pulley is a sister block, and baffle plate is arranged between sister block; There is the convex annular edge at described coaster base center, and the convex edge is built-in with circular rotating basis; Be fixed with the lead baffle plate on the described pulley on the end-stopping plate.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: the tight releasing pulley of this strain insulator steel pipe pole is owing to adopt said structure, single-sheaved block or sister block are by affixed rotating basis in arc duct and coaster base, and place top, cross-arm chassis, shortened the space length of lead and strain insulator string hanging point, there was not traction problems, and can adapt to the tight unwrapping wire of different angles by the radian rotation in arc duct, strain insulator-string hangs up easily during stringing; The pulley upper end is fixed with the lead baffle plate, avoids lead to deviate from pulley, reduces lead and is undermined the phenomenon of scrapping; Simple installation is quick, and is safe and reliable, but and a tractor serves several purposes.

Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Tight releasing pulley using method of this strain insulator steel pipe pole and design principle are: as shown in Figure 4, coaster 1 is fixed on the cross-arm chassis 8 by coaster chassis bolt hole and strain insulator string hanging point 10 with bolt, guarantee coaster fastness and stability in use, according to line direction, set bolt by rotating basis 3, pulley is adjusted to suitable angle, so that traction is during unwrapping wire, wick or lead pass through smoothly; Open lead baffle plate 2, wick or lead are put into pulley groove, the lead baffle plate 2 that closes, and tighten with bolt, avoid wick or lead to go out groove and block coaster and wear phenomenon.Allow the space length of lead and strain insulator string hanging point 10 near as far as possible during unwrapping wire, can guarantee so accurately to print, can bring great convenience to stringing work again, so this coaster is installed in above the cross-arm, the distance of the about 10cm of conductor spacing strain insulator-string hanging point during unwrapping wire, there was not traction problems, strain insulator string is easy to hang up during stringing, and by adjusting the set bolt of rotating basis, can make pulley rotation arbitrarily in the radian scope in arc duct, to adapt to the tight unwrapping wire of different angles, satisfy the unwrapping wire demand of strain insulator bar fully, and can not block the phenomenon of lead.
