Abstract
The invention discloses a cable head pulling-out tool of a ring main unit. The cable head pulling-out tool comprises a barrel-shaped metal body and a metal buckle piece, wherein a screw hole is formed in the barrel bottom of the metal body, a threaded rod is arranged on the barrel bottom of the metal body, a notch is formed in the barrel wall of the metal body, the notch is provided with the detachable metal buckle piece, and a through hole capable of being matched with a lead-out section of a cable head is defined by the metal buckle piece and the notch in an enclosing mode. The cable head pulling-out tool has the advantages that the buckle piece and a metal die is connected with a metal die by means of a circular ring, fastness and reliability are achieved, and stability requirements are met; an iron chain is removed, the buckle piece is directly utilized to drive the cable head, and damage to the cable head due to nonuniform stress can be effectively prevented; the circular ring with an opening in one side is utilized to be placed in for fixation, so convenience and fast performance are achieved.
Description
Technical field
The present invention relates to a kind of puller, more specifically, it relates to a kind of ring main unit cable end puller.
Background technology
When electric power overhaul, sometimes need cable end is extracted outside cabinet.In 10kV distribution ring main unit, due to the cabinet body structure reason, operation cable end is for many years extracted very difficult, even extract, also easily cable end and cabinet sealing is caused to damage.Prior art adopts the cable unplugg is cut cable end is extracted outside cabinet.Waste time and energy, and cause the breakage of cable unplugg, can't recycle, cause certain economic loss.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of rational in infrastructure, simple to operate, can not destroy the ring main unit cable end puller of cable unplugg.
This ring main unit cable end puller, the metal body, the metal cramp that comprise tubbiness, bottom of the barrel at described metal body has a screw and is provided with screw rod, have a breach on the bucket wall of metal body, described breach is provided with the Demountable metallic cramp, and described metal cramp and breach surround the through hole of an energy and the cooperation of the cable end section of drawing.
As preferably: the connection of described metal cramp and metal body is by the circular rings of anchor ear.
As preferably: the L shape of described metal cramp for fitting with cable end.
As preferably: described circular rings is used two stainless steel metal semicircle both sides dock and be provided with screw to lock and is used the butterfly nut.
As preferably: the breach had on the bucket wall of described metal body is for semicircle.
The invention has the beneficial effects as follows: 1. adopt round ring connection cramp and metal die solid and reliable, meet stability requirement.2. removing iron chains directly uses cramp drive cable end can effectively prevent the damage that discontinuity causes cable end.3. use the round ring of openings at one side to put into convenient fixing quick.
The accompanying drawing explanation
Fig. 1 is master's TV structure schematic diagram of the present invention;
Fig. 2 is side-looking structural representation of the present invention;
Fig. 3 is the cable end schematic diagram;
Fig. 4 is that the present invention uses state reference map;
Reference numeral: metal body 1, screw rod 2, metal cramp 3, circular rings 4, cable end 5, through hole 6.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.Although the present invention is described in connection with preferred embodiment, should know, do not mean to limit the invention in described embodiment.On the contrary, the present invention will be contained alternative, modified model and the equivalent in the scope of the present invention that can be included in attached claims restriction.
Referring to shown in Fig. 1 to Fig. 4, ring main unit cable end puller of the present invention, the metal body 1, the metal cramp 3 that comprise tubbiness, bottom of the barrel at described metal body 1 has a screw and is provided with screw rod 2, have half circumferential notch on the bucket wall of metal body 1, described breach is provided with Demountable metallic cramp 3, and described metal cramp 3 and breach surround the through hole 6 of an energy and the cooperation of the cable end section of drawing.The connection of described metal cramp 3 and metal body 1 is by the circular rings 4 of anchor ear.The L shape of described metal cramp 3 for fitting with cable end 5.Described circular rings 4 is used two stainless steel metal semicircle both sides to dock and be provided with locking butterfly nut with screw.Butterfly nut place screw rod is longer, the convenient adjustment.Metal body 1 bottom welding is firm, and screw rod 2 precessions in bottom are smooth and easy, and the anterior cut shape becomes the semicircle shape breach to conform to the cable end size, and polishes smooth.
While buckling into cable end, only the butterfly nut need be unscrewed and cable end can be put into.And then the butterfly nut is tightened, cramp 3 is fixedly connected with metal body 1, then the turn screw rod 2, utilize Electromotor Reparation to draw the horse principle, make metal body 1 and cramp 3 drive cable end 5 cable end 5 is extracted outside cabinet.
