Description
Technical Field
The utility model relates to a live working tool for power transmission and transformation, in particular to a remote indirect split device for a split pin.
Background
In the operation and maintenance of the power transmission line, the split pin is installed on a screw rod on a connecting hardware fitting, a cross arm and other components and used for limiting a split pin and a closed pin of a nut on the screw rod, and the split pin can fall off frequently due to wind vibration, irregular process, corrosion, materials and other reasons. Such defect is critical defect, if the pin in case takes place to drop, is unknown at fortune dimension personnel, under the condition that does not find this defect in the tour, under the effect such as wind vibration, very easily takes place the nut and drops from the screw rod, and the screw rod has the serious risk of backdraft broken string from the risk that the drift bolt hole drops.
The method for processing the hidden troubles of the defects at the present stage is two methods of line power failure additional installation and live working equipotential operation additional installation. The power failure operation and live-line operation equipotential operation are subjected to factors such as a power grid operation mode, whether reclosing can be stopped or not, load loss, power protection of important users and the like, so that the hidden danger of the defects can not be eliminated in a short time, and the safe and stable operation of a line is influenced.
In the process of eliminating the defects through live working, a tool for indirectly installing the screw cap is already available and patented, after the screw cap is indirectly installed, the split pin needs to be additionally installed, the supporting legs at the tail part of the split pin are broken off, and the current tool cannot finish the task of breaking off the two legs at the tail part of the split pin.
Disclosure of Invention
The utility model provides a cotter pin remote indirect cotter device, aiming at solving the technical problem that one supporting leg at the tail part of a cotter pin cannot be broken off when the cotter pin is additionally arranged in a long distance in the existing power transmission and transformation operation.
The utility model is realized by adopting the following technical scheme: a remote indirect split device of a split pin comprises a connecting rod, wherein the tail part of the connecting rod is provided with a connecting thread for connecting an insulating rod; the middle front end of the connecting rod is bent to one side by a certain angle, the front end of the bent part forms a first tip end, the middle front end of the connecting rod is connected with an installation plate, and the position of the installation plate is opposite to the bending direction of the first tip end; a bolt is fixed on the mounting plate, the axial direction of the bolt is perpendicular to the axial direction of the connecting rod, a second tip is sleeved on the bolt in a rotating mode, and a locking knob connected to the bolt through threads is further arranged on the outer side of the second tip.
When the split type split pin opening device is used, the locking knob is firstly unscrewed, then the opening angles of the two tips are adjusted, the locking knob is screwed after the adjustment, the insulating rod is connected to the tail part of the opening device through threads, then the split pin opening device is stretched to the position of a split pin with operation by holding the insulating rod by hand, one tip is sleeved in the ring opening of the split pin, the other tip abuts against the longer one of the two supporting legs of the split pin, and then the insulating rod is rotated, so that the longer split pin is broken.
The split pin support leg opening device is simple in structure and convenient to operate, solves the technical problem that a device capable of remotely opening split pin support legs is not available at present, and is suitable for popularization in the industry.

Detailed Description
Example 2 in example 1, the first and second pointed bodies are shaft-shaped, and the tips thereof are tapered; the tail end of the second tip 2 is flat, so that the second tip can be better attached to a mounting plate and is convenient to fasten.
The second tip 2 is provided with a hole at the end through which the second tip is movably sleeved on the bolt 7, and the second tip is only movably sleeved on the bolt and is not in threaded connection with the bolt. The locking knob is provided with a cavity in the center, the inner wall of the cavity is provided with an internal thread, the locking knob is screwed on the screw rod of the bolt through the internal thread, the knob can move on the screw rod and press the second tip end, and the locking knob can be loosened through reverse screwing. The first and second tips are substantially uniform in length.
As shown in fig. 3, a threaded hole is formed in the mounting plate 6, and the bolt 7 is connected with the threaded hole through threads; the head of the bolt 7 is positioned on the side, opposite to the side where the locking knob 3 is positioned, of the mounting plate 6, and the head is embedded in the mounting plate 6 (in a counter bore structure), so that the structure is more compact. One side of the threaded hole far away from the second tip is of a flaring structure, and the head of the bolt can be clamped.
The external thread is opened to the afterbody of connecting rod 5, and 5 afterbody of connecting rod are fixed with a limiting plate 8 before the external thread for withstand the front end of insulator spindle, make the operation more stable.
The locking knob 3 is a butterfly knob.
Fig. 4 and 5 are schematic structural views of the cotter pin in a normal state and one leg after being bent.
When the split pin locking device is used, the locking knob is loosened, then the sharp angles of the second tip and the first tip are adjusted to enable the sharp angles to be almost equal to the distance between the sharp angles and the ring opening at the tail of the split pin and the longer leg, then the insulating rod is connected, the split pin locking device extends forwards to enable the first tip (or the second tip) to extend into the ring opening of the split pin, the second tip (or the first tip) is clamped below the longer leg of the split pin, and the longer leg of the split pin can be bent by rotating the insulating rod as shown by an arrow in the insulating rod below the figure 6. Because the cotter pin is inserted into the pin hole on the screw rod (clamped and sent into the pin hole by the pliers connected with the long rod), the position of the cotter pin is basically limited and blocked, so when the split pin support is used, the split pin support can be bent easily. The cotter pin is generally positioned at the tail end of the screw, so the screw does not influence the implementation of the utility model; during manufacturing, the first tip end and the second tip end are manufactured and selected to be proper in length according to actual needs, and the bending operation of the split pin supporting leg can be guaranteed to be completed in practical application.
