In order to achieve the above objectives, using following technical scheme:
A kind of linear string tower head end replacing insulator connection gold utensil, more suitable for linear string tower head end first insulator
It changes, is generally employed in pairs comprising adjustment type T-type fitting, anti-deprotection bolt, anti-deprotection fastener and back guard circle, institute
The cross-arm both ends that anti-deprotection fastener is set to the adjustment type T-type fitting are stated, the anti-deprotection bolt is set to described anti-
It is deprotected the outside of fastener, for preventing the anti-deprotection fastener from falling off, the back guard circle is set to the adjustment type T
The upper end center position of type fitting, the lower end of the adjustment type T-type fitting are connected with screw rod, and the lower end of the screw rod is provided with silk
Bar connection is lower to block, and is arranged with a spanner on the screw rod, is gone up and down by the cooperation of spanner and screw rod, to realize insulator
It extracts.
Lengthening joint is additionally provided between the screw rod and the adjustment type T-type fitting.
The anti-deprotection fastener includes the concave part for buckle, and the lower end of the concave part is provided with bolt, tower head
After hanging point main material both ends are placed in the concave part, locked by the bolt.
Compared with prior art, the utility model has the following beneficial effects:
The utility model linear string tower head end replacing insulator connection gold utensil, is fixed on pylon by adjusting formula T-type fitting
On, and by the way that anti-deprotection bolt and back guard circle is arranged, enhance the safety of the device, there is applied widely, operation letter
The features such as list, high safety, dual anti-drop protective device, single replacement.Adjustment type T-type connection gold utensil can be according to actual use
It is adjusted and fixes, there is high promotional value.

Specific embodiment
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of linear string tower head end replacing insulator connection gold utensil, including adjustment type T-type fitting 10, anticreep
Protect bolt 30, anti-deprotection fastener 20 and back guard circle 40.
Adjustment type T-type fitting 10 includes cross-arm and the vertical connector perpendicular to cross-arm, and the both ends of cross-arm are connected by bolt
The anti-deprotection fastener 20 is connect, anti-deprotection fastener 20 includes groove 21, and a bolt is arranged in the steel structure bottom for forming groove
22,80 end accommodation of main material of tower head hanging point is in groove 21, then is subject to the fastening of bolt 22.
The outermost end of cross-arm is additionally provided with anti-deprotection bolt 30, for preventing anti-deprotection fastener from falling off.
The intermediate position of cross-arm is provided with back guard circle 40, in device in use, connecting guard circle by cord, prevents
Bolt adjustment type T-type connection gold utensil 10 is fallen again to fall off when filling.
The lower end of vertical connector is connected with screw rod 50, and the lower end of screw rod 50 is provided with the lower card 60 of screw rod connection, and screw rod connects
It connects lower card 60 to be fixed on third piece insulator, by the later lifting lead wire of 50 stress of screw rod, reaches replacement first insulator
Purpose.
In order to expand the scope of application of the fitting, one or more lengthenings can be added between screw rod and vertical connector
Connector 70 (70 '), so that in varied situations, can guarantee that the lower card 60 of screw rod connection can snap on third piece insulator.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment is not to limit
The scope of the patents of the utility model, all equivalence enforcements or change without departing from carried out by the utility model, is intended to be limited solely by this case
In the scope of the patents.
