Abstract
The utility model discloses an anti-dropping hook of an electric insulation protection umbrella and relates to a protecting tool for live working of a power transmission line. The anti-dropping hook is provided with a hook body, a rotatable anti-dropping clamping plate is installed at the position of an opening arranged at the lower end of the hook body, a pull rope is installed at the end of the anti-dropping clamping plate, and a pull ring is installed on the pull rope. The anti-dropping hook has the advantages that a tension spring is utilized to draw the anti-dropping clamping plate, a hook opening is clamped, the effect of preventing a wire from dropping from the hook opening is achieved, the problem of accidental unhooking is solved, and the anti-dropping hook is simple to install and convenient to operate.
Description
Technical field
The utility model relates to the protection tool in the hot line maintenance, specifically is the anticreep hook under a kind of electric insulation protective umbrella made.
Background technology
The ultra-high-tension power transmission line operation during charged work, hangs up the safety that insulated umbrella can be protected the staff effectively on the charged lead in upper strata on the shaft tower of multilayer cross-arm; But not insurance of the hook door of traditional insulated umbrella hook; Break off relations easily, not only reduced of the protection of high-voltage protection instrument, threaten personal safety the operating personnel; And it causes falling object from high altitude, threatens ground staff's personal safety.
Summary of the invention
To the deficiency of above-mentioned technology, the utility model provides the hook of the anticreep under a kind of electric insulation protective umbrella made, prevents the come off effect of lead from the mouth of hook, has solved the problem of unexpected unhook, and easy for installation, and operation is prone to row.
The utility model is realized with following technical scheme: a kind of electric insulation protective umbrella made anticreep hook, comprise coupler body, and a rotating anticreep clamp is installed at the lower ending opening place of coupler body; A stay cord is installed in the end of anticreep clamp, and a draw ring is installed on the stay cord.
The utility model has the advantages that:
1, use draw ring, handling safety is reliable, and is simple and easy to do, ensured the live line working work safety, prevents
Falling object from high altitude.
2, utilize the active force of extension spring as the anticreep clamp, clamp draw ring effect action bars work fulcrum, convenient
Dismounting, safe and reliable.
3, alignment pin is effectively adjusted the clamp position.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, clamp draw ring, 2, junction button, 3, stay cord, 4, alignment pin, 5, extension spring, 6, the anticreep clamp, 7, coupler body, 8, lead.
Embodiment
Shown in accompanying drawing, a kind of electric insulation protective umbrella made anticreep hook has a coupler body 7, the lower ending opening place of coupler body 7 that a rotating anticreep clamp 6 is installed; A stay cord 3 is installed in the end of anticreep clamp 6, and a draw ring 1 is installed on the stay cord.
Draw ring is installed for ease, a fixing junction button 2 on draw ring 1, draw ring 1 is connected with stay cord 3 through junction button 2.Anticreep clamp 6 tail ends are fixed on the lower end of coupler body 7 opening parts through alignment pin 4 and extension spring 5, and an end of extension spring 5 is installed on the anticreep clamp 6, and the other end is installed on the coupler body 7 of steady pin lower end.
The course of work: operating personnel are choosing the draw ring 1 in the mousing-hook with insulating bar; The mouth of hook did not have anticreep clamp 6 and stopped this moment; After hanging over the correct position on lead 8 external diameters to insulated umbrella, when regaining insulating bar, under the pulling force of extension spring 5, anticreep clamp 6 is put down; Seal the hook door, reach the purpose that prevents that coupler body 7 and lead 8 from breaking off relations.When removing hook, use insulating bar to choose draw ring 1 equally,,, draw back anticreep clamp 6, can anticreep clamp 6 be regained, discharge coupler body 7 through stay cord 3 tractions as long as overcome extension spring 5 pulling force.
