Three, summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, provides that a kind of modern design is unique, simple and reasonable, easy to use, operating efficiency is high and the triangular insulating hanging fulcrum bar that fail safe is good.
Technical scheme of the present invention is: a kind of triangular insulating hanging fulcrum bar, containing insulating support rod, insulating cord and insulated tension pole, described insulating support rod upper end is fixed with connecting rod, one end of described connecting rod and the upper end thereof of described insulated tension pole are fixed, the lower end of described insulated tension pole is provided with metal hook, the other end of described connecting rod is connected with a fixed pulley, described fixed pulley is provided with insulating cord, one end of described insulating cord is provided with rope hook, the other end of described insulating cord is arranged on two-way locking ratchet-wheel wire tightener, described two-way locking ratchet-wheel wire tightener is arranged on the bottom of described insulating support rod, the lower end of described insulating support rod is provided with U-shaped card base.
Described insulating support rod and insulated tension pole are made by epoxy resin fiberglass enhanced type composite material.
Described insulated tension pole is two-part structure, and the pole different by two thicknesses is formed, wherein, thick pole upper end and described connecting rod hinged fixing, ramuscule bar upper end is sleeved in the axis hole of described thick pole, is fixed by bolt or alignment pin, and described ramuscule bar lower end is provided with described metal hook.
Described ramuscule bar upper end arranges at least two location holes, and described location hole is for described bolt or alignment pin location.
The invention has the beneficial effects as follows:
1, the present invention adopts leg-of-mutton design concept, to make it reach the most stable force structure in the engineering changing pin insulator, in addition, adopts epoxy resin fiberglass enhanced type composite material as main insulation material, has good electric property.
2, the present invention is provided with two-way locking ratchet-wheel wire tightener, the insulating cord that spreads out of from fixed pulley or insulating tape can be controlled, solve the problem that insulating cord is fixing, changing original other types instrument insulating cord needs artificial traction and fixing pattern on ground, adds fail safe.
3, the effective insulated lengths of the present invention is greater than 0.6 meter ensure that insulated lengths, improve the fail safe in operation, shorten the activity duration, operating personnel also has 4 original people to be reduced to 2 people, improve efficiency, better solve operating personnel and electrified body hypotelorism, safe distance is not enough, movable conducting wire can not the problem such as locking.
4, ramuscule bar lower end of the present invention arranges the metal hook be made up of high-strength metal material, its upper end devises multiple location hole to be applicable to all types of cross-arms of different length, insulating support rod bottom adopts the U-shaped design of special angle, reliably can fix with the bolt of protector anchor ear.
5, the present invention has unique, simple and reasonable, easy to use, operating efficiency is high and fail safe is good etc. feature novel in design, and it is applied widely, has good economic benefit after popularization.
Four, accompanying drawing illustrates:
Fig. 1 is the structural representation of triangular insulating hanging fulcrum bar.
Five, embodiment:
Embodiment: see in Fig. 1, figure, 1-U type card base, 2-insulating support rod, 3-ratchet, the two-way locking ratchet-wheel wire tightener of 4-, 5-rope hook, 6-insulating cord, 7-fixed pulley, 8-connecting rod, 9-insulated tension pole, 10-metal hook.
Triangular insulating hanging fulcrum bar contains insulating support rod 2, insulating cord 6 and insulated tension pole 9, wherein: insulating support rod 2 upper end is fixed with connecting rod 8, one end of connecting rod 8 and the upper end thereof of insulated tension pole 9 are fixed, the lower end of insulated tension pole 9 is provided with metal hook 10, the wheel carrier of the other end of connecting rod 8 and a fixed pulley 7 is hinged fixing, fixed pulley 7 is provided with insulating cord 6, one end of insulating cord 6 is provided with rope hook 5, the other end of insulating cord 6 is arranged on two-way locking ratchet-wheel wire tightener 4, two-way locking ratchet-wheel wire tightener 4 is arranged on the bottom of insulating support rod 2, the lower end of insulating support rod 2 is provided with U-shaped card base 1.
