Description
Technical field
The utility model relates to a kind of charged mounting or dismounting split pin device.
Background technology
In the service work of transmission line actual motion, find, circuit is in service least attracts attention that normal safe operation plays huge practical function to circuit in but very crucial split pin.Because the reasons such as split pin is aging, foreign matter hook cause the split pin disappearance, it is the major hidden danger of line security.And, when the split pin disappearance is found, consider safe distance factor and technical problem, can only process by the method for interruption maintenance at present.The normal conditions interruption maintenance has two kinds of modes: a kind of is to adopt the mode of coordinating the power failure batch process, and another kind is to have a power failure to rush to repair the processing mode of key position.And these two kinds of modes adopt any power supply reliability that all directly affects.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above of prior art existence and a kind of charged mounting or dismounting split pin device is provided, and dismounting split pin under charged prerequisite, overhauled split pin without specially having a power failure, and is conducive to ensure power supply.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: charged mounting or dismounting split pin device, it is characterized in that comprising matrix, with the detachable insulating bar be connected of matrix, be fixed on tearing the pin hook open and being articulated in the pad part on matrix on matrix, described matrix is provided with the dress cotter way, be provided with the split pin support in described dress cotter way, the working end of described pad part is placed in the dress cotter way and matches with the split pin support, and the operating portion of described pad part extends to outside described dress cotter way.Under charged prerequisite, by the charged mounting or dismounting split pin device dismounting split pin of present patent application, without specially having a power failure split pin is overhauled, be conducive to ensure power supply.
As further improving and supplementing technique scheme, the utility model adopts following technical measures: in order to make the pad part, centered by pivoting point, swing smoothly, the operating portion of described pad part arranges a pull-push piece, and described pull-push piece coordinates with the operating portion of pad part is detachable.The purpose that the pad part swings, for pushing split pin, conveniently is inserted in target location by split pin smoothly, and makes the backswing of pad part, and split pin is locked on target location smoothly.
In order to make the pad part to smooth limited the exerting pressure of split pin, described pad part is L-shaped, and the corner of L shaped described pad part is articulated on matrix by bearing pin.
For the pad part is swung smoothly, described dress cotter way also comprises the convolution section that the voltage supply pin member swings.
In order to coordinate the installing ring of split pin end, facilitate installing ring to be contained in smoothly the dress cotter way, and prevent the arbitrarily mobile or rotation of installing ring position, described split pin support end is the enlarging shape.
For handled easily, the described pin hook of tearing open stands in base side walls, and is fixedly connected with matrix.
The beneficial effect the utlity model has: 1, dismounting split pin under charged prerequisite, without specially having a power failure split pin is overhauled, is conducive to ensure power supply.2, for the pad part is swung smoothly centered by pivoting point, the operating portion of described pad part arranges a pull-push piece.3, in order to make the pad part to smooth limited the exerting pressure of split pin, the pad part is L-shaped.4, in order to coordinate the installing ring of split pin end, facilitate installing ring to be contained in smoothly the dress cotter way, and prevent the arbitrarily mobile or rotation of installing ring position, split pin support end is the enlarging shape.
