Abstract
The utility model discloses a strengthened lead lifting fixture, which solves the technical problem that at present, a fixture is likely to deform and tear in a groove position when a linear tower of power transmission lines lifts the power transmission lines in a live-line state. The fixture comprises a groove plate (1) and a vertical principal material (6) of a cross arm, wherein a groove (5) is arranged in the groove plate (1), the vertical principal material (6) of the cross arm is clamped in the groove (5), a nut (2) of a leading screw is arranged on the groove plate, a leading screw (3) is in screw joint into the nut (2) of the leading screw, a power transmission line (4) is hitched to the bottom end of the leading screw (3), and a strengthened inclined support (7) is arranged between the groove plate (1) and the vertical principal material (6) of the cross arm. The strengthened lead lifting fixture can be directly applied to live-line lead lifting in the linear tower of the power transmission lines, which is especially suitable for power transmission line lifting for towers in large span and large distance.
Description
Technical field
When relating to a kind of straight line pole live line working, the utility model promotes the employed a kind of jig of lead.
Background technology
When the live line working of transmission line straight line pole promotes transmission pressure, generally be to adopt a kind of jig that is stuck on the cross-arm, this jig is provided with the special-purpose screw mandrel that promotes of aluminium alloy, and the design peak load is 19.6 thousand Ns.The draw-in groove that arranges on this jig fixedly is connected on the facade master material of cross-arm, the maximum perpendicular load reached more than 15,000 Ns when general 220kV circuit promoted lead, can reach more than 20,000 Ns for big leap, big span shaft tower, because the jig of clamping is that single-point is fixed on the shaft tower cross-arm, stress point concentrates on the facade of cross-arm, when promoting lead, because cross-arm master material discontinuity, very easily make jig in draw-in groove place distortion and tear, jig is damaged, the fault that goes offline jeopardizes operating personnel's life when serious.
Summary of the invention
The utility model provides a kind of reinforced type lead wire to promote jig, solve existing transmission line straight line pole live line working when promoting transmission pressure employed jig in draw-in groove place easy deformation and the technical problem of tearing.
The utility model is to solve above technical problem by the following technical programs:
A kind of reinforced type lead wire promotes jig, the facade master material that comprises draw-in groove plate and cross-arm, the draw-in groove plate is provided with draw-in groove, the facade master material of cross-arm is connected in the draw-in groove, the draw-in groove plate is provided with feed screw nut, in feed screw nut, be bolted with leading screw, be mounted with transmission pressure in the bottom of leading screw, between the facade master material of draw-in groove plate and cross-arm, be provided with the reinforcement diagonal brace.
One end of described reinforcement diagonal brace is fixedlyed connected with the draw-in groove plate by bolt, and the other end of strengthening diagonal brace is that the facade master material with cross-arm welds together.
The utility model can be applied directly in the operation of transmission line straight line pole live line working lifting lead, is particularly suitable for the lifting to the transmission pressure of big leap, big span shaft tower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
