Abstract
The invention relates to an insulation protection hook for live-working wire lifting of a distribution line. The insulation protection hook comprises a lifting hook body, wherein a mounting hole is formed at the end part of one side of the lifting hook body; and the lifting hook body on the side of the mounting hole is articulated with an anti-drop block arm which is located at a wire inlet/outlet of the lifting hook body. The insulation protection hook for live-working wire lifting of a distribution line, provided by the invention, has the advantages of reasonable structure, skilful design and high practicability; and by using the insulation protection hook, the working time can be greatly shortened, the working efficiency is improved, the working process is simplified, and the working intensity is reduced.
Description
Technical field:
The present invention relates to the Line tool of carrying in the electric power live line working field, especially a kind of distribution line live working is carried line and is used the insulation protection hook.
Background technology:
When carrying out the 10KV distribution line live working; Run into the situation that promotes or land lead through regular meeting; At present use the little suspension hook of aerial lift device with insulated arm to promote and put down lead usually during operation at the scene; Because the little suspension hook of aerial lift device with insulated arm is not a specific purpose tool, its shape and size and lead are misfitted, and therefore in this type of work, use very inconvenience; Can't directly hook the lead that protects mask; And lead also comes off from little suspension hook easily, so the staff must move to the work bucket on the position of to be hoisted or landing lead when operating at every turn, is wrapped in little suspension hook on the lead that protects mask together with the pull rope that insulate; To work again bucket rises or drops to service position operation arm and carries out lifting or the landing operation of lead to electric pole, thereby has wasted the time greatly, increased the fussy degree of operating and staff's working strength.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, provide a kind of distribution line live working reasonable in design, simple in structure, easy to use, that can increase work efficiency, reduce labour intensity to carry line and use the insulation protection hook.
The objective of the invention is to realize through following technological means:
A kind of distribution line live working is carried line and is used the insulation protection hook; It is characterized in that: comprise a main hook part; One side end of this main hook part is made an installing hole, and hinge is adorned a slip-off preventing blocking arm that is positioned at main hook part wire inlet-outlet place on the main hook part of this installing hole side.
And described slip-off preventing blocking arm is the arc blocking arm.
And, be connected a back-moving spring between described slip-off preventing blocking arm and the main hook part, and the rear end roof pressure of this blocking arm is on main hook part.
And the opening of said main hook part up.
And the end side of said main hook part is made one and is tilted to the outer turnover line guide plate that is provided with.
Advantage of the present invention and good effect are:
1, this insulation protection hook is made up of opening main hook part and hinge dress slip-off preventing blocking arm above that up; This protection hook is connected use with the little suspension hook of aerial lift device with insulated arm; The staff can directly promote or land and protect the lead of mask in the service position; And prevent that lead from ejecting from suspension hook, thereby shortened the operating time greatly, promoted operating efficiency.
2, therefore the lead because this insulation protection of use hook can directly go up and down has been simplified workflow, has been reduced working strength.
3, a turnover line guide plate is made in the main hook part end of this insulation protection hook, and this guide plate is tilted to outer the setting, therefore in the lead turnover, can play guide effect, makes things convenient for lead to pass in and out smoothly.
4, the present invention is that a kind of rational in infrastructure, design distribution line live working ingenious, easy to use is carried line and used the insulation protection hook, uses this insulation protection hook to practice thrift the operating time greatly, increases work efficiency, simplifies workflow and reduces working strength.
Description of drawings:
Fig. 1 is a front view of the present invention.
Embodiment:
Be described in detail embodiments of the invention below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
A kind of distribution line live working is carried line and is used the insulation protection hook, comprises a main hook part 5, and a side end of this main hook part is made an installing hole 4, and this installing hole is used to connect hanging device.A free bearing is installed on the main hook part of this installing hole side; This free bearing is adorned the slip-off preventing blocking arm 2 of an arc through hinge 3 hinges; The rear end roof pressure of this blocking arm is on main hook part; The front end of this blocking arm is positioned at main hook part wire inlet-outlet place, and is connected a back-moving spring between this slip-off preventing blocking arm and the main hook part.When reality is used, the opening of main hook part up, the slip-off preventing blocking arm can stop lead to eject from the wire inlet-outlet of main hook part.
Get in the main hook part for the ease of lead, the main hook part end side make one be tilted to outer setting turnover line guide plate 1.
