Abstract
The utility model relates to an upturned pulley for live installation of a zinc oxide lightning arrester on four-bundle conductors of a 500kv power transmission line. The upturned pulley comprises a straight beam and two cant beams symmetrically installed at the two ends of the straight beam in an inclined manner, and the top end of each cant beam is provided with a locking device. A hoisting pulley is installed on the straight beam, and a bolt is installed on the upper portion of the hoisting pulley to form a protective cap. The upturned pulley is connected with two upper conductors of the four-bundle conductors through locking devices, the two cant beams are 100mm in length, and the straight beam is 60mm in length and can prevent forward and backward inclination. A bolt is installed above the pulley of the hoisting pulley to form a protective cap. The hoisting point is increased, the vertical height of the bolt is 20mm lower than the vertical height of the locking devices, and the hoisting point is 20mm lower than conductors on two sides. Hoisting stroke is increased, and the stability of equipotential persons is improved. Since the hoisting stroke is sufficient, installation of a zinc oxide lightning arrester or other devices on four-bundle conductors is labor-saving and time-saving.
Description
Technical field
The utility model relates to a kind of coaster, especially relates to charged installation zinc oxide arrester on a kind of 500kV transmission line conductors on quad bundled and uses towards sky coaster.
Background technology
The need of work equipotential personnel of the charged installation zinc oxide arrester of tradition 500kV transmission line conductors on quad bundled are at diverse location installing insulating rope and the coaster of wire, but the not enough installation difficulty of the too low installation stroke of coaster suspension centre and both sides wire are vacillated now to the left, now to the right by force unbalance personnel.
Utility model content
The technical problems to be solved in the utility model is to provide the charged installation zinc oxide arrester of a kind of 500kV transmission line conductors on quad bundled and uses towards sky coaster.This coaster utilizes locking device to be connected with two upper conductors of conductors on quad bundled, on straight beam mounting strap over cap towards sky coaster, improve suspension centre, improved lifting stroke and increased equipotential personnel's stability.
The problem existing in order to solve prior art, the technical solution adopted in the utility model is:
On 500kV transmission line conductors on quad bundled, charged installation zinc oxide arrester is used towards sky coaster; include straight beam and cant beam; cant beam is two; the symmetrical two ends that are arranged on straight beam tilt; the top of cant beam is provided with locking device; hanging pulley has been installed on straight beam, and the top of playing hanging pulley is provided with bolt and forms over cap.
Described straight beam length is 60mm, and cant beam length is 100mm.
Described locking device includes spill fixture and matrix movable part, spill fixture is fixedly connected on the end of cant beam, matrix movable part is flexibly connected with cant beam, on matrix fixture, is hinged with bolt, and matrix movable part and matrix fixture are movably connected by bolt.
The advantage that the utility model has and effect:
1, the utility model is connected with two upper conductors of conductors on quad bundled by locking device; the two long 100MM of cant beam, the long 60MM of straight beam can prevent from tilting forward and back; the top of playing the pulley of hanging pulley is provided with bolt and forms over cap; improved suspension centre; the vertical height of bolt is lower than the vertical height 20mm of locking device; suspension centre, lower than both sides wire 20mm, has improved lifting stroke, has increased equipotential personnel's stability.Because lifting stroke is sufficient, while therefore zinc oxide arrester and miscellaneous equipment being installed on conductors on quad bundled, can play time saving and energy saving effect.
2, guarantee that equipotential personnel do not vacillate now to the left, now to the right and more improve stability with wire in lifting process.
