Description
Technical field
The utility model belongs to electric power apparatus examination technical field of tools, relates to a kind of universal slide bolt rotary extrusion type spinning earth rod of protection personal safety when carrying out interruption maintenance operation on power circuit equipment.
Background technology
Ground connection rod conventional in electric power system now has two kinds: spiral compression formula and spring compression type, their each pluses and minuses of having oneself by oneself.Spiral compression formula contact-making surface is reliably fastening, but the operating time is long.Spring compression type substantially reduces the operating time, but always damages problem because of spring, there will be the not reliable fastening problem of contact-making surface.Therefore a lot of unit all adopts spiral compression formula this operating time longer, the reliable fastening earth rod of contact-making surface.But the wire clamp part of this earth connection generally uses the rotary bayonet socket fixing cord of the trapezoidal bolt of coarse thread.Which is by the rotating insulated rod of operating personnel, makes earthing wire clip part bolt move upward conductor clamping, and because bolt uses coarse thread trapezoidal thread, wire clamp opening line-spacing length, nearly 6-8CM, bolt are about 25-40 tooth.Install and remove use time, bolt rotates that to tighten the time long, unscrews wire clamp and is convenient to wire and enters or exit, have line-spacing over half to be nearly backlash.Thus cause this kind of mode to rotate tightening or unscrew the time long, on electric pole, assembly and disassembly operations process is very long, uses the spiral compression formula earth rod upkeep operation personnel labor intensity time-division strong, very inconvenient, and mounting or dismounting efficiency is low and waste time and energy.
In recent years, the requirement of people to power supply reliability is more and more higher, and electric power enterprise is all being shortened construction and suddenly repairing the time, to ensure to continue to power to client by each method.But electric power enterprise organizes earth connection for guaranteeing that personal security must be hung by field condition more in service work, and to guarantee upkeep operation personnel personal safety, the duration of dress folding earth connection is longer.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of universal slide bolt rotary extrusion type spinning earth rod, and it can shorten the time of dress, dismounting ground wire work greatly, thus greatly reduces the labour intensity of operating personnel.
The utility model solves the technical scheme that its technical problem adopts: a kind of universal slide bolt rotary extrusion type spinning earth rod, comprise a columniform insulating rod, this insulating rod is installed with a chuck crotch, a chuck pressing plate is then provided with corresponding with it immediately below this chuck crotch, this chuck pressing plate can coordinate fixing cord with chuck crotch, this chuck pressing plate is fixed on one and is positioned on insulating rod shank of bolt, a support is socketed with outside this shank of bolt, in this support side be provided with one with the screw thread casting die of shank of bolt threaded engagement, a circle groove is provided with outside this support, a circular arc pin be bolted is provided with in groove, this groove has a T-shaped hole, two springs are respectively placed with in T-shaped hole, spring supporting screw thread casting die, circular arc pin then can be made to be pressed on spring when insulating rod rotates, spring then inwardly compresses, screw thread casting die is made to be engaged with shank of bolt thus shank of bolt is fixed, shank of bolt can only be spinned motion in support.
Described chuck crotch is fixed by circular arc pin, in support inner rotary or can be fixed on insulating rod.
The lower end of described shank of bolt is connected with insulation spillikin.
Described chuck pressing plate to be coordinated with bolt hole by bolt on the connecting rod that both can be fixed on and shank of bolt also can be fixed on and be installed on shank of bolt.
When described chuck pressing plate is fixed on shank of bolt, circular arc pin is then fixed on chuck crotch seat, then separately be set with an insulation operation up knob at needs outward at the insulating rod of this section when described chuck pressing plate is fixed on connecting rod, this circular arc pin is then fixed on insulation operation up knob.
The bottom of described insulation spillikin is then fixedly linked with insulation operating handle, between insulating rod bottom and insulation spillikin, be provided with nylon centring ring.
Described screw thread casting die is socketed in support.
The beneficial effects of the utility model are: slide bolt rotary extrusion type spinning earth rod shortens the time of dress, dismounting ground wire work, thus greatly reduces the labour intensity of operating personnel.Stand and tighten a phase earth rod on the ground and make time of its clamping wire for using spiral compression formula earth rod more than 30 second, using spring compression type earth rod about 3 seconds, and use slide bolt rotary extrusion type spinning earth rod to need 3-5 second, institute close to spring compression type earth rod is fast free, but really reach the tightness of spiral compression formula earth rod, combine the advantage of two kinds of conventional now earth rods.When power circuit equipment carries out upkeep operation, organize earth connection for guaranteeing that the safety of operating personnel must be hung more, conventional spiral compression formula wire clamp earth connection is used often to organize operating time clock more than about 3 points, use the slide bolt rotary extrusion type spinning earth rod of advantage that this time improve, that combine spiral compression formula and spring compression type, operating time is one of three of spiral compression formula, close to the operating time of spring compression type, and contact-making surface fastening reliability reaches the effect of now conventional spiral compression formula earth connection.
