Abstract

The utility model discloses an insulating cross arm capable of adjusting location of a wire. The insulating cross arm comprises a cross arm, wherein a movable cambered seat is sleeved on the cross arm and comprises a square insulating pipe and an insulating fixed block; the insulating fixed block is arranged on the outer surface of the upper pipe wall of the square insulating pipe; the upper surface of the insulating fixed block is provided with a cambered groove; axis of the cambered groove is perpendicular to that of the square insulating pipe; and the lower pipe wall of the square insulating pipe is provided with a threaded hole in which a locking bolt is screwed. In the insulating cross arm, the movable cambered seat is sleeved on the cross arm, so that the movable cambered seat moves on the cross arm to meet the requirements of live working in the case of nonstandard wire distance when the distance between wires is not standard due to inclination of a cement concrete rod; and the insulating cross arm is extremely convenient to use.

Description

Can regulate the insulator crossarm of lead position location
One, technical field: the utility model relates to the insulator crossarm that a kind of earth potential live operation is used, and particularly relates to a kind of insulator crossarm of regulating the lead position location.
Two. background technology: at present, the hotline maintenance power circuit has the branch of earth potential working method and medial potential working method, and what adopt that insulation trembles that the arm car carries out livewire work is the medial potential working method; In place with a varied topography, the arm car is trembled in insulation can't be close, can not implement medial potential working, thereby often adopt the earth potential working method to carry out charged work.And what be provided with on the livewire work insulator crossarm that uses now all is holddown groove, and when cement concrete bar inclined position caused separation nonstandard, the use of insulator crossarm just was restricted.
Three. the utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of insulator crossarm of the lead regulated position location reasonable in design, simple in structure, applied widely and easy to use is provided.
The technical solution of the utility model is: a kind of insulator crossarm of regulating the lead position location, contain the cross-arm arm, be set with portable arc seat on the described cross-arm arm, described portable arc seat contains square insulation tube and insulation fixed block, described insulation fixed block is arranged on the external surface of described square insulation tube upper tube wall, the upper surface of described insulation fixed block is provided with deep-slotted chip breaker, the axis of this deep-slotted chip breaker and the axis normal of described square insulation tube.
The following tube wall of described square insulation tube is provided with screwed hole, is combined with lock bolt in this screwed hole.
The beneficial effects of the utility model are:
1, the portable arc seat of suit on the utility model cross-arm arm, when cement concrete bar inclined position caused separation nonstandard, portable arc seat was just mobile on the cross-arm arm, to adapt to the demand of conductor spacing livewire work when nonstandard, used very convenient.
2, the portable arc seat of the utility model is provided with lock bolt, can be fixed at any time on the cross-arm arm, and place the location of being convenient to lead.
3, the utility model is reasonable in design, simple in structure, applied widely and easy to use, is particularly useful for earth potential live operation on the 10KV overhead wire concrete bar, has good economic benefit after the popularization.
Four. description of drawings:
Fig. 1 is the structural representation that can regulate the insulator crossarm of lead position location;
Fig. 2 is the right view of portable arc seat shown in Figure 1.
Five. the specific embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, the 1-fixed block that insulate, the square insulation tube of 2-, 3-lock bolt, 4-cross-arm arm, 5-column.
The insulator crossarm that can regulate the lead position location contains cross-arm arm 4, cross-arm arm 4 is fixedlyed connected with column 5, be set with portable arc seat on the cross-arm arm 4, portable arc seat contains square insulation tube 2 and insulation fixed block 1, insulation fixed block 1 is arranged on the external surface of square insulation tube 2 upper tube walls and (can adopts welding, also can adopt bolt to connect, determine as required), the upper surface of insulation fixed block 1 is provided with deep-slotted chip breaker, the axis normal of the axis of this deep-slotted chip breaker and square insulation tube 2.The following tube wall of square insulation tube 2 is provided with screwed hole, is combined with lock bolt 3 in this screwed hole.
When adopting the earth potential working method to carry out charged work, when cement concrete bar inclined position causes separation nonstandard, move square insulation tube 2, make its deep-slotted chip breaker corresponding with lead location, when adjusting the position of square insulation tube 2, lock bolt 3 precessions make square insulation tube 2 be fixed together with cross-arm arm 4.

Claims (2)

1. the insulator crossarm that can regulate the lead position location, contain the cross-arm arm, it is characterized in that: be set with portable arc seat on the described cross-arm arm, described portable arc seat contains square insulation tube and insulation fixed block, described insulation fixed block is arranged on the external surface of described square insulation tube upper tube wall, the upper surface of described insulation fixed block is provided with deep-slotted chip breaker, the axis of this deep-slotted chip breaker and the axis normal of described square insulation tube.
2. the insulator crossarm of regulating the lead position location according to claim 1 is characterized in that: the following tube wall of described square insulation tube is provided with screwed hole, is combined with lock bolt in this screwed hole.
