Abstract
The utility model discloses a pin pulling device for a high-voltage circuit porcelain bottle. The pin pulling device comprises a rod piece, the rear end of the rod piece is connected with an insulated operating rod through screw threads, the front end of the rod piece is provided with a T-shaped head, the length of the front end of the T-shaped head vertical to the axis direction of the rod piece is 25 millimeters, and the middle part of the rod piece is circularly bent. The front end of the pin pulling device for the high-voltage circuit porcelain bottle is provided with the T-shaped head, and the transverse length of the front end of the T-shaped head is 25 millimeters and is slightly greater than the width of the small end of a W-shaped spring pin and slightly smaller than the opening width of the large end of the W-shaped spring pin; when the W-shaped spring pin along the circuit needs to be taken down, an operator only needs to push the small end of the W-shaped spring pin by using the T-shaped head, and the spring pin can be conveniently taken down; when a new spring pin is replaced, the T-shaped head is blocked into the opening of the large end of the W-shaped spring pin, and the new spring pin can be installed by pulling along the circuit direction; and the pin pulling device is convenient to operate the W-shaped spring pin along the circuit.
Description
Technical field
The utility model relates to instrument, and particularly the power transmission lines overhauling instrument specifically is a kind of split-pin device that is used for the high-tension circuit porcelain vase.
Background technology
In the 220KV ultra-high-tension power transmission line, be extensive use of insulator, needed to use W shape spring catch connector in the insulator, according to the difference of insulator installation position, the suitable line direction that W shape spring catch has, what have is vertical with line direction.After using a period of time, because air corrosion and insulator rock the W shape spring catch that makes in the insulator with the wind and can lose efficacy, at this moment need the W shape spring catch that more renews, for W shape spring catch perpendicular to line direction, adopt existing pliers gripping usually, just can realize, and for the W shape spring catch along circuit, because pliers is fixed on the insulating bar, be not easy to exert oneself along line direction, use the pliers inconvenient operation.
Summary of the invention
The purpose of this utility model is to provide a kind of split-pin device that is used for the high-tension circuit porcelain vase, and the described this split-pin device that is used for the high-tension circuit porcelain vase will solve the technical problem that the available technology adopting pliers is got W shape spring catch inconvenience.
The purpose of this utility model is achieved through the following technical solutions: this split-pin device comprises a rod member, this rod member rear end is connected with insulating bar by screw thread, the rod member front end is provided with T connector, and the T connector front end is 25mm perpendicular to the length of center line of the bar direction.
This rod member middle part is convexly curved.
This split-pin device length overall is 150mm, and rod member middle part is that the reinforcing bar of 10mm constitutes by diameter, and the front end T connector is that the reinforcing bar of 5mm welds with this rod member front end and constitutes by diameter.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with T connector at the split-pin device front end that is used for the high-tension circuit porcelain vase, lateral length before the T connector is 25mm, width than W shape spring catch small end is big slightly, and it is slightly littler than its big end opening width, when needs take off the W shape spring catch that carries over circuit, the operator only need promote the small end of W shape spring catch with this T connector, just can take off spring catch easily, and when more renewing spring catch, snap in the big end opening of W shape spring catch by T connector,, can install new spring catch along the line direction pulling, for W shape spring catch, easy to operate along circuit.This rod member middle part is convexly curved, and when operation, can clearly observe the position of front end T connector like this.
