Abstract
The utility model discloses a bending board card for replacing a 110/220kV double-string tension insulator string. The bending board card comprises a yoke plate connecting end and a calabash connecting end. The yoke plate connecting end is provided with a neck for clamping a yoke plate, wherein the length S of the neck is less than the distance h between the bending board card and yoke plate connecting point and the twin socket and yoke plate connecting point. The bending board card of the utility model is an improvement of an existing bending board card, the twin socket will not be pressed by the stress fulcrum of the bending board card, the possibility of screw breaking can be eliminated, potential risks can be eliminated, the personal safety of operators can be ensured, the connection mode between the calabash and the bending board card is optimized, the operation is easy, and the working efficiency can be improved.
Description
Technical field
The utility model relates to the instrument used when a kind of power industry is changed insulator string, is specifically related to a kind of for changing the bent plate card of the two string of 110/220kV strain insulator string.
Background technology
Need to use the bent plate card while changing the two string of 110/220kV strain insulator string, when changing two string strain insulator string, the yoke plate link of bent plate card is clamped yoke plate by draw-in groove and is connected with yoke plate, the cucurbit link is connected with cucurbit, in Renewal process, cucurbit has substituted the stressed of insulator string, and the bent plate card is by stressed outside translation one segment distance of cucurbit, in order to stay enough spaces to picking and placeing of insulator string.The bent plate card used at present, draw-in groove is deep, its length equals or exceeds bent plate card and yoke plate tie point to the distance between twin sockets and yoke plate tie point, make the stressed fulcrum of bent plate card be pressed on twin sockets, there is great potential safety hazard in this, because the twin sockets place that the bent plate card is pushed down in maintenance process is stressed large, easily make screw rod distortion or fracture, not only can cause equipment deficiency, also can make cucurbit lose stressed, an other insulator string causes string under the effect of wire impulsive force, threaten operating personnel's personal safety, increased operating personnel's risk.In addition, the bent plate card used at present, the cucurbit link is connected with cucurbit by steel cable, needs two manual manipulations during operation, work high above the ground, speed is dangerous again slowly.
The utility model content
Technical problem to be solved in the utility model is, overcomes above defect, provides a kind of improved, easy and simple to handle, safe for changing the bent plate card of the two string of 110/220kV strain insulator string.
In order to solve the above technical problem, the utility model is a kind of for changing the bent plate card of the two string of 1 10/220kV strain insulator string, comprise yoke plate link and cucurbit link, be useful on the draw-in groove of clamping yoke plate on the yoke plate link, the length of described draw-in groove is less than bent plate card and yoke plate tie point to the distance between twin sockets and yoke plate tie point.
Further, cucurbit link described in the utility model is disposed with connecting plate and instrument is U-shaped.
The utility model has mainly carried out the improvement of two parts to existing bent plate card, at first be the improvement to the bent plate card draw-in groove degree of depth, slotting position shoals, make the length of described draw-in groove be less than bent plate card and yoke plate tie point to the distance between twin sockets and yoke plate tie point, like this, the bent plate card is stressed on yoke plate but not on twin sockets, has avoided associated safety hidden danger in operation process; Next considers the connectivity problem of bent plate card and cucurbit, U-shaped by installing a connecting plate and instrument additional, and while being connected with cucurbit, hook directly hooks that instrument is U-shaped just can be connected, a hand can complete, make and connect easily, improved operating efficiency, also increase fail safe.Just can use bent plate card replacement twin sockets and right angle link plate after improvement in work afterwards, can directly change golden part.
The beneficial effects of the utility model: by the transformation to the bent plate card, make the stressed fulcrum of bent plate card no longer push down twin sockets, eliminated the possibility that screw rod breaks, guaranteed operating personnel's personal safety, the risk class during the operation of use bent plate card is reduced to acceptable degree; Eliminated in maintenance process the screw pressure at twin sockets place, be unlikely to make the screw rod distortion after maintenance, become urgent defect; Optimize connected mode, improved the connected mode of cucurbit and bent plate card, convenient operation, improved operating efficiency.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model draw-in groove position view;
Fig. 3 is the utility model and yoke plate connection diagram;
Fig. 4 is existing bent plate card and yoke plate connection diagram;
Fig. 5 is connecting plate described in the utility model and the U-shaped structural representation of instrument.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model is a kind of for changing the bent plate card of the two string of 110/220kV strain insulator string, comprise yoke plate link 1 and cucurbit link 2, be useful on the draw-in groove 3 of clamping yoke plate on yoke plate link 1, the length S of described draw-in groove 3 is less than bent plate card and yoke plate tie point to the distance h between twin sockets 4 and yoke plate tie point.
Further, cucurbit link 2 described in the utility model is disposed with connecting plate 5 and instrument U-shaped 6.
Embodiment mono-: the utility model is the improvement to existing bent plate card, the length S of described draw-in groove 3 is less than bent plate card and yoke plate tie point to the distance h between twin sockets 4 and yoke plate tie point, like this, on stressed on the yoke plate 7 and not twin sockets 4 of bent plate card, effectively avoid potential safety hazard in operation process, set gradually connecting plate 5 and be connected with the pin of cucurbit link 2 with instrument U-shaped 6, while being connected with cucurbit, hook directly hooks instrument U-shaped 6 and just can connect, a hand can complete, very convenient.
These are only part execution mode of the present utility model, as long as used the above technical scheme, all should fall into protection range of the present utility model.
