Abstract
The utility model relates to an insulator anticreep device in overhead power line fitting anticreep field. The device is the upper and lower staple bolt of semi -ring shape that can surround the bowl head in the outside setting of bowl head, and is fixed through connecting bolt, go up the staple bolt middle part and be equipped with the through -hole, and the staple bolt middle part is equipped with interior arch down. Bellied setting in fixed insulator pin of its usable upper and lower staple bolt and the bowl head, the through -hole of especially going up the staple bolt and staple bolt down can reliably be fixed a position upper and lower staple bolt and effective and implemented spacing to the bulb, guarantees promptly that the bulb among the insulator chain is not deviate from from bowl head, can satisfy the normal rotation of bulb in the bowl head again. The reliable invention mesh of realizing. Have simultaneously that simple structure is suitable for, spacing dependable performance, that the installation is dismantled is convenient, reduce the maintenance cost, the advantage such as be fit for promoting.
Description
Technical field
The utility model relates to a kind of line hardware anti-drop device, specifically, relates to a kind ofly be arranged on the anti-drop device preventing bulb from deviating from from bowl head in the V-type suspension insulator of overhead transmission line.
Background technology
In built on stilts ultra-high-tension power transmission line, be provided with V-type suspension insulator, the ball-and-socket connected mode that described V-type suspension insulator adopts bulb gold utensil to be connected with socket-clevis eye mostly makes insulator string strain with transmission line.In this syndeton, bulb is placed in the ball-and-socket of bowl head, because bowl cephalic par has a microscler connecting hole, in transmission line running, its circuit is in the severe natural environment in field for a long time, especially under the strong friction effect of large wind generation, cause the heavy wear of bulb and bowl head, original locking device will lose locking effect, bulb is impelled to deviate from from the microscler connecting hole of bowl cephalic par, existing V-type suspension insulator is mostly without anti-drop device, add the error that bulb and bowl head are processed, more increase the weight of friction, and then add the probability that bulb deviates from from bowl head.After bulb is deviate from from bowl head, namely cause insulator string to fall the accident of string, have a strong impact on the safe and stable operation of transmission line.
Summary of the invention
The purpose of this utility model is to provide a kind of insulator anti-drop device, mainly solve existing V-type suspension insulator without anti-drop device, the problem that bulb in ball-and-socket connected mode is easily deviate from from bowl head nest, thus effectively avoid insulator string to fall the accident of string, guarantee the safe and stable operation of transmission line.
Scheme of the present utility model is as described below
:it comprises connecting bolt, by the upper and lower anchor ear of semi-circular that bowl head can be surrounded in bowl head outer setting, fixes, be provided with through hole, and be provided with internal projection in the middle part of lower anchor ear in the middle part of described upper anchor ear through connecting bolt.
the beneficial effects of the utility model:owing to taking described structure, the relative position of upper and lower anchor ear fixed insulation bulbec head and bowl head can be utilized, particularly go up the through hole of anchor ear and the setting of lower anchor ear internal projection, reliably can locate upper and lower anchor ear and effectively to implement bulb spacing, namely ensure that the bulb in insulator string is not deviate from from bowl head, can meet again the normal rotation of bulb in bowl head.Reliably realize goal of the invention.There is structure simultaneously be simply suitable for, spacing dependable performance, easy installation and removal, reduction maintenance cost, be applicable to carrying out the advantage such as promoting.
Accompanying drawing explanation
Fig. 1 is insulator anti-drop device structural front view;
The vertical view of Fig. 2 Fig. 1;
Fig. 3 is insulator anti-drop device installation site schematic diagram;
Fig. 4 is that the A of Fig. 3 is to schematic diagram.
Embodiment
Insulator anti-drop device shown in Fig. 1 arranges the upper and lower anchor ear 1,2 of semi-circular that bowl head can be surrounded in bowl head outside and ball cap place, is provided with through hole 3, and is provided with internal projection 4 in the middle part of lower anchor ear 2 in the middle part of described upper anchor ear 1.Upper and lower anchor ear 1,2 corresponding, two ends are connected and fixed with bowl capitiform integral through connecting bolt 5.
The utility model is arranged on the ball cap place of bowl head in transmission line " V " type suspension insulator, is enclosed within clamping screw by the through hole 3 on described upper anchor ear 1, and the internal projection 4 on lower anchor ear 2 is just corresponding with the microscler connecting hole of bowl cephalic par.This device can when bulb and bowl head locking device lose efficacy, and the position of restriction bulb, makes bulb can not deviate from from bowl head nest.Avoid causing insulator string to fall the accident of string, significantly improve the security reliability that transmission line runs.
