Abstract
The anti-wire pumpback device of a kind of line bar, comprise line bar, cross-arm, cross-arm arranges the top of online bar, and the two ends of cross-arm arrange anti-wire pumpback device; The technical scheme of technical solution problem is that anti-wire pumpback device comprises U-shaped support, binding bolt, connection bracket, lock sleeve, semicircle tapered sleeve, holds out against spring, spring supporting post.Good effect of the present utility model is: when wire pulls wire along semicircle tapered sleeve from small end to large end, wire can pass through smoothly, and when et out of order wire comes off from cross-arm, wire can not from the large end pumpback of semicircle tapered sleeve to small end, blocked by semicircle tapered sleeve, thus avoid accident to occur.
Description
Technical field
The utility model relates to a kind of anti-wire pumpback device.
Background technology
In line construction work; after new stringing pole completes; install new cross-arm; moulding aluminum steel to need to be pulled on by fixed pulley, is in general moulding aluminum steel and need carrying out pulling up simultaneously and ensure that cross-arm stress equalization is unlikely to turn, if cross-arm discontinuity equalization of cross-arm both sides; the wire of such as side because of certain fault drop time; serious twisting can be there is in cross-arm, can cause line bar therefrom between fracture, and then cause personal injury.
Summary of the invention
The purpose of this utility model is to provide the anti-wire pumpback device of a kind of line bar, to solve the aforementioned problems in the prior.
The utility model comprises line bar, cross-arm, cross-arm arranges the top of online bar, the two ends of cross-arm arrange anti-wire pumpback device, and the technical scheme of technical solution problem is: described anti-wire pumpback device comprises U-shaped support, binding bolt, connection bracket, lock sleeve, semicircle tapered sleeve, holds out against spring, spring supporting post; U-shaped support, connection bracket are fixed on cross-arm by binding bolt, the open end of connection bracket installs lock sleeve, the endoporus of lock sleeve is conical, lock sleeve arranges locking slot, the in-built semicircle tapered sleeve of endoporus of lock sleeve, the large end end face of semicircle tapered sleeve arranges supported hole, and endoporus, the cylindrical of semicircle tapered sleeve are taper shape, and its cylindrical matches with the tapered bore of lock sleeve; The large end end face connection of semicircle tapered sleeve holds out against spring, the rear end of the other end and lock sleeve that hold out against spring is connected, hold out against in spring eye and arrange spring supporting post, one end of spring supporting post is connected with the rear end of lock sleeve, and the other end of spring supporting post is in the supported hole of the aft end face of lock sleeve.
The cylindrical of described lock sleeve is arranged adjustment bolt.
The material of described semicircle tapered sleeve is plastics.
The endoporus of described semicircle tapered sleeve arranges ring-like anti-slip tank.
Good effect of the present utility model is: when wire pulls wire along semicircle tapered sleeve from small end to large end, wire can pass through smoothly, and when et out of order wire comes off from cross-arm, wire can not from the large end pumpback of semicircle tapered sleeve to small end, blocked by semicircle tapered sleeve, thus avoid accident to occur.
