Abstract
The utility model relates to a tong type pin removal, consisting of pin removing tongs, an insulation operation lever, an insulation traction dynamic rope, a spring and a bolt. The front end of the insulation operation lever is connected with the pin removing tongs by the bolt; the spring is arranged among the handles of the pin removing tongs, and the insulation traction dynamic rope is tightened on the handles of the pin removing tongs. The pin removal is portable, flexible, safe, stable and convenient to be operated, thereby shortening one time of the whole working process, greatly reducing labor intensity of operators and risk of hot-line work and improving the whole skill of operators. The utility model is a comparatively practical tool.
Description
Technical field
The utility model relates to a kind of instrument that is used for ultra-high-tension power transmission line charged for replacement straight line insulator string.
Background technology
At present, during ultra-high-tension power transmission line charged for replacement straight line insulator string, whether the earth potential electrician can adopt action bars and pin pulling out device fast, accurately a charged side bowl inner peg is extracted the efficient that directly has influence on overall work.Traditional way has two kinds: the one, adopt destroy method, with action bars pin is got a bit from a bowl deutostoma, hold this point with action bars then, pull out from whole destruction of a bowl deutostoma, this method wastes time and energy, if run into the hard pin of short pin or steel fire, have only it is broken and could take out.Another kind is the slidingtype pin removal, though adopt the success rate of the laborsaving son of pulling pin of this kind method not high, the pin of extracting falls (dangerous) easily and pin removal itself is fragile.
Summary of the invention
The purpose of this utility model provides a kind of jaw type pin removal, pin in the insulator charged side bowl head can disposablely be extracted, and success rate has improved operating speed greatly more than 90%, reduced electrician's task difficulty on the bar, the speed of charged for replacement straight line insulator is doubled.
The purpose of this utility model is achieved in that by the pincers of pulling pin, insulating bar, insulation traction power rope, spring, bolt to be formed, the insulating bar front end connects the pincers of pulling pin by bolt, pulling pin has spring between the handle that clamps, and on the handle of the pincers of pulling pin being has insulation traction power rope.
Because the utility model adopts said structure, this pin removal: light, flexible, safety and stability, be convenient to operation, make whole job flow time shorten one times, greatly reduce operating personnel's labour intensity and the risk that has reduced live line working, having improved the whole technical ability of operating personnel, is practical a kind of instrument.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
1 pull pin pincers, 2 insulating bars, 3 insulation traction power ropes, 4 springs, 5 bolts among the figure.
Embodiment
Embodiment: form by the pincers 1 of pulling pin, insulating bar 2, insulation traction power rope 3, spring 4, bolt 5, insulating bar 2 front ends connect the pincers 1 of pulling pin by bolt 5, pulling pin has spring 4 between pincers 1 the handle, and on the handle of the pincers 1 of pulling pin being has insulation traction power rope 3.
Pincers 1 one side handles of will pulling pin are welded on the band iron, and on the band iron punching be connected on the insulating bar 2, and at annulus of the end of this side handle welding, spring 3 that twines making with iron wire of welding then, it is insulation traction power rope 2 that the pincers 1 opposite side handle lengthening of pulling pin, elongated portion hold into that the U type is convenient to.Pull pin and draw back spring 4 slightly before the son, the jaw of the pincers 1 of pulling pin under the effect of spring 4 tension force opens, and puts into a bowl head-clamp and lives spring catch, one draws insulation traction power rope 2 gently, just spring catch is accurately taken out.
Holding the system spring with iron wire does not have any elastic limit, being welded in pincers 1 inboard of pulling pin the arbitrarily size of pincers 1 jaw of pulling pin like this, pulls pin at different pins and clamps 1 jaw and arbitrarily adjust; Employed insulating bar 2 and insulation traction power rope 3 must can use through electrical test is qualified, and will keep enough safe distances in electrified body in use.The time spent will in time not be stored in charged toolhouse.
Claims (1)
1. jaw type pin removal, form by the pincers of pulling pin, insulating bar, insulation traction power rope, spring, bolt, it is characterized in that: the insulating bar front end connects the pincers of pulling pin by bolt, between the handle of the pincers of pulling pin spring is arranged, and on the handle of the pincers of pulling pin being has insulation traction power rope.
