Description
Technical field
The present invention relates to a kind of 500KV synthetic insulator special ladder.
Background technology
Along with the quickening of power grid construction, in order to improve the reliability of electrical network, reduce the time of overhaul of the equipments in recent years, transmission line of electricity has been applied a large amount of composite insulators.In composite insulator and repairing wire process, for protection composite insulator is not subject to artificial damage, generally use the upper and lower composite insulator of rope ladder.But in this process, exist the drawback can not be ignored: first, rope ladder in use requires colligation firm, and rope ladder itself is heavier, when one man operation, be easy to hang while partially causing upper and lower rope ladder more difficult; The problem that also will consider insulator length in the process of hanging rope ladder swings back and forth in the situation that having wind, is difficult to make rope ladder lower draw-bar to be suspended to wire place, occasions a delay the time.Secondly, after the suspension of rope ladder is good, depending on composite insulator, operating personnel is in upper and lower rope ladder process, cause rope ladder local pressure excessive, can make rope ladder be partial to composite insulator, in addition the gravity of human body will and composite insulator between produce larger friction, cause the wearing and tearing of composite insulator full skirt.Again, using rope ladder to check the composite insulation period of the day from 11 p.m. to 1 a.m, due to the suspension angles problem of rope ladder own, be difficult to, from multi-angle, insulator is carried out to comprehensive inspection, can not improve and check on the quality.The main cause that causes above-mentioned drawback is that the two ends of rope ladder cannot be strained.
Summary of the invention
Object of the present invention, is to provide a kind of 500KV synthetic insulator special ladder, and it can be strained rope ladder, eliminates the drawback that existing cat ladder exists, thereby, can solve the problem that prior art exists.
The object of the invention is to be achieved through the following technical solutions: 500KV synthetic insulator special ladder, comprise bandlet, the first tightening device and the second tightening device are installed respectively in the two ends of bandlet, the structure full symmetric of the first tightening device and the second tightening device; The first hook is installed on the first tightening device, the second hook is installed on the second tightening device; The several pedals of the parallel installation in two ends of bandlet; Cable wire is installed at the middle part of bandlet, and grasp is installed on cable wire; The first tightening device by housing, ratchet, axle, tighten up roller, torsion spring, ratchet spanner, spring leaf and ratchet and connect and compose; Horizontal installation shaft on housing, the left and right, two ends of axle passes the outer each ratchet spanner of installing of housing, and between two ratchet spanneres, mounting knob is installed and is tightened up roller; Axle middle part is installed and is tightened up roller, and the two ends of bandlet are connected with the roller that tightens up of the first tightening device and the second tightening device respectively; Ratchet is installed on axle, and ratchet is between housing and ratchet spanner, and on housing, ratchet is installed in activity, and ratchet engages with ratchet, mounting spring sheet on housing, and spring leaf contacts with ratchet and makes ratchet compress ratchet; Torsion spring is installed on axle, and one end of torsion spring is connected with ratchet spanner, and the other end is connected with housing; Pine band handle is installed on ratchet.
For further realizing object of the present invention, can also realize by the following technical solutions: the first hook is provided with the first swivel nut, the first safety plug is installed in the first swivel nut, the first safety plug is threaded with the first swivel nut; The second hook is provided with the second swivel nut, and the second safety plug is installed on the second swivel nut, and the second safety plug is threaded with the second swivel nut.Carrying roller is installed in the bottom of housing, and carrying roller can rotate relative to housing.
Good effect of the present invention is: two hanging points are arranged at its top, and a hanging point is arranged at bottom, and upper and lower hanging point forms stable triangle, and cat ladder is difficult for rotation.It is also equipped with distinctive tightening device, in the time hanging cat ladder, can open tightening device, emits sufficiently long bandlet, fixing so that operating personnel hang described cat ladder.Upper hanging point has installed safety plug additional, can prevent that hanging point from, by coming off on circuit, having improved safety factor.Tightening device can make the cat ladder can be exceptionally straight, and the upper and lower convenient safety of operating personnel has also been avoided the damage to insulator simultaneously.Lower hanging point adopts grasp, and wire in easier hook in the time of lower hook has also improved stability simultaneously.This cat ladder two ends all arrange the hook of fixing use, after hanging up properly, can tighten up rope ladder by tightening device, cat ladder is fixed by external force, no longer arbitrarily wave, thereby eliminated the hidden danger in operation, reduced operating personnel's labour intensity, improve operating efficiency, also avoided the wearing and tearing of rope ladder Insulators simultaneously.It also has advantages of compactness simple for structure, cheap for manufacturing cost and easy and simple to handle.
