Three, summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiency of prior art, provide that a kind of modern design is unique, simple and reasonable, easy to use, high efficiency and the good triangular form insulation of fail safe hang pole.
Technical scheme of the present invention is: pole is hung in a kind of triangular form insulation, contains insulating support rod, insulation rope and insulated tension pole, and said insulating support rod upper end is fixed with connecting rod; One end of said connecting rod and the upper end hinged securement of said insulated tension pole; The lower end of said insulated tension pole is provided with metal hook, and the other end of said connecting rod is connected with a fixed pulley, and said fixed pulley is provided with the insulation rope; One end of said insulation rope is provided with rope hook; The other end of said insulation rope is arranged on the two-way locking ratchet wire grip, and said two-way locking ratchet wire grip is installed in the bottom of said insulating support rod, and the lower end of said insulating support rod is provided with U type card base.
Said insulating support rod and insulated tension pole are processed by the epoxy resin fiberglass enhanced type composite material.
Said insulated tension pole is the two-part structure, is made up of two different poles of thickness, wherein; Thick pole upper end and said connecting rod hinged securement; Ramuscule bar upper end is sleeved in the axis hole of said thick pole, fixes through bolt or alignment pin, and said ramuscule bar lower end is provided with said metal hook.
Said ramuscule bar upper end is provided with at least two location holes, and said location hole supplies said bolt or alignment pin location to use.
The invention has the beneficial effects as follows:
1, the present invention adopts leg-of-mutton design concept, so that it reaches the most stable force structure in the engineering of changing pin insulator, in addition, adopts the epoxy resin fiberglass enhanced type composite material as the main insulation material, has good electric property.
2, the present invention is provided with two-way locking ratchet wire grip; Can control insulation rope or the insulating tape that spreads out of from fixed pulley; Solved the fixing problem of insulation rope, having changed original other types instrument insulation rope needs artificial traction and fixing pattern on the ground, has increased fail safe.
3, the effective insulated lengths of the present invention greater than 0.6 meter to have guaranteed insulated lengths; Improved the fail safe in the operation; Shortened the activity duration; The operating personnel also has 4 original people to be reduced to 2 people, has improved efficient, better solved operating personnel and electrified body hypotelorism, safe distance not enough, move lead can not locking etc. problem.
4, ramuscule bar of the present invention lower end is provided with the metal hook of being processed by high-strength metal material; A plurality of location holes have been designed so that be fit to all types of cross-arms of different length in its upper end; The U type design of special angle is adopted in the insulating support rod bottom, make its can with the bolt secure fixation of protector anchor ear.
5, the present invention has characteristics such as unique, simple and reasonable, easy to use, high efficiency novel in design and fail safe are good, and it is applied widely, has good economic benefit after the popularization.
Four, description of drawings:
Fig. 1 hangs the structural representation of pole for the triangular form insulation.
Five, embodiment:
Embodiment: referring to Fig. 1, among the figure, 1-U type card base, 2-insulating support rod, 3-ratchet, the two-way locking ratchet of 4-wire grip, 5-rope hook, the 6-rope that insulate, 7-fixed pulley, 8-connecting rod, 9-insulated tension pole, 10-metal hook.
The triangular form insulation is hung pole and is contained insulating support rod 2, insulation rope 6 and insulated tension pole 9; Wherein: insulating support rod 2 upper ends are fixed with connecting rod 8, an end of connecting rod 8 and the upper end hinged securement of insulated tension pole 9, and the lower end of insulated tension pole 9 is provided with metal hook 10; The wheel carrier hinged securement of the other end of connecting rod 8 and a fixed pulley 7; Fixed pulley 7 is provided with insulation rope 6, and an end of insulation rope 6 is provided with rope hook 5, and the other end of insulation rope 6 is arranged on the two-way locking ratchet wire grip 4; Two-way locking ratchet wire grip 4 is installed in the bottom of insulating support rod 2, and the lower end of insulating support rod 2 is provided with U type card base 1.
