Closed type fixture used for replacing electrical china bottle

Abstract

A closed type fixture used for replacing an electrical china bottle is composed of a front fixture, a back fixture and two lead screws; a crank is fixed on the middle portion of each of the two lead screws, and the two ends of each of the two lead screws are respectively connected with connecting sleeves in a rotary mode; and hinged through holes are formed in the end portions of the connecting sleeves. The closed type fixture used for replacing the electrical china bottle is characterized by further comprising a riding plate fixture, hinged holes corresponding to the hinged through holes formed in the connecting sleeves are formed at the two ends of the riding plate fixture; and a groove extending from the end face to the middle portion is formed at one end of the riding plate fixture, and the shape of the bottom wall of the groove is matched with the outer contour shape of an object to be attached to the grooves. According to the closed type fixture used for replacing the electrical china bottle, after the riding plate fixture is added on the basis of prior closed type fixture components, and the purpose that china bottles at the head and tail ends of bigeminy-string insulators are replaced conveniently is newly added by the use of the hinging between hinge connecting shafts and bigeminy-plates and by the fact that the fastened locking for position is achieved by the use the same shape between the bottom wall of the groove and the outer contour shape of the contacting face of the bigeminy-plates.

Description

【Technical field】 [0001] The invention relates to a closed jig for replacing electric porcelain bottles. [0002] 【technical background】 [0003] At present, the tool usually adopted for the replacement of the double-series insulator porcelain bottle of the transmission line is a closed fixture. The structure of this closed fixture includes a front clamp, a rear clamp and a screw rod, and a screw handle is provided in the middle of the screw rod. When in use, open the movable cover of the front and rear clamps, hold the porcelain bottle, make the front clamp fit into the steel cap groove of the porcelain bottle, and tighten the joint nut. Shake the handles of the two screw rods, and tighten the two screw rods at the same time until the porcelain bottle to be replaced is loose, and then take out the pin of the porcelain bottle to come out and replace the porcelain bottle. But the existing closed fixture of this structure is only applicable to the replacement of the single-p...

Problems solved by technology

However, the existing closed fixture of this structure is only suitable for the replacement of the single-piece insulator porcelain bottles in the middle of the double series, and it is helpless for the replacement of the head and end porcelain bottles.

Of course, the operator can also choose a large knife card or a bent plate card to cooperate with the bottle holder for replacement. However, due to the need to be equipped with a heavier connecting plate and bottle holder, plus high-altitude operations, if you encounter complex terrain such as mountainous areas, It is not only inconvenient to transport and carry, but also time-consuming and labor-intensive, which seriously affects the power supply reliability of transmission lines.
