Description
Technical field
The present invention relates to a kind of electric company's power distribution live-wire auxiliary equipment, belong to power distribution live-wire field, specifically
Say it is a kind of fuse switch lead fixed mount in ground.
Background technology
In the routine work of electric company, charged for replacement fuse switch belongs to 33 classes of power distribution live-wire development
One of events in operation, fuse switch is changed at present mainly three kinds of handling situations：One kind is directly cut-out drop type fusing
The upper end power supply of device, then changes fuse switch；Another kind is that the upper end of fuse switch is powered, disables lower end load
After change fuse switch；Also one kind is that on-load changes fuse switch.Three kinds of above-mentioned situations, fall in replacing
During formula fuse, it is required for that first the upper lead insulation fall prevention rope of fuse switch is tied on main line, lower lead insulation
Fall prevention rope is tied on cross-arm.In the fixation procedure of upper lead, first fall prevention rope is tied on main line by insulation bucket, due to leading
Line phase spacing is nearer, is easy to encounter wire or nearby device during mobile insulation bucket, increased the danger of operation
Property.Moving up and down for insulation bucket, virtually expands job area, increased the labour intensity of operating personnel.And lead quilt
Tie up to respectively above main line and cross-arm, they are in a kind of suspended state, touch in wind or by mistake in the case of, it is easy to
Rocking for lead is caused, if lead masking is not talked about sternly, very big potential safety hazard can be brought to livewire work.
The content of the invention
It is an object of the invention to provide a kind of simple structure, easy to use, need not be anti-using insulation in operation process
Pendant rope, can be effectively prevented from the swing of lead by upper and lower lead fixation, and the drop type for improving live-working safety melts
Disconnected device lead fixed mount.
In order to reach object above, the technical solution adopted in the present invention is：A kind of fuse switch lead is fixed
Frame, including trip bolt, insulation board and wing nut, it is characterised in that：The two ends of described insulation board are symmetrical to be fixed with absolutely
Edge arm, the free end of insulation arm is arranged with telescopic arm, and telescopic arm is provided with the trip bolt of threaded connection, and trip bolt is passed through to be stretched
Screw and insulation arm contact on contracting arm, the outer end of telescopic arm are fixed with buckle, and the free end of buckle is provided with Duckbill type and opens
Mouthful, lead is fixed in Duckbill type opening, insulation board is provided with the through hole of the strip consistent with insulation board axis direction,
One end of insulating bar is fixed with insulation grab, the other end of insulating bar through after the through hole on insulation board with wing nut screw thread
Connection, support column is held within the insulation board outer wall immediately below through hole, and two buckles, insulation grab and support columns are all located at
The same side of insulation board.
The insulation spacer being set on insulating bar is provided between described insulation board and wing nut.
Described buckle, trip bolt, insulation arm, insulation board, insulating bar, wing nut, insulation spacer, support column and absolutely
Edge grab is epoxy resin material, and described telescopic arm is makrolon material.
The upper end of described trip bolt is fixed with handle.
The beneficial effects of the present invention are：1st, in charged for replacement fuse switch, it is not necessary to which mobile insulation bucket goes again
System's insulation fall prevention rope, reduces the moving range of the bucket that insulate in operation, simplifies the process of charged for replacement fuse switch, drops
The low labour intensity of operating personnel；2nd, the position in through-holes of the actual size regulation insulating bar according to cross-arm, by insulation
Grab and the support column mating reaction being fixed on insulation board, insulation board is securely fixed on cross-arm；3rd, on trip bolt
Face is fixed with handle, livewire work personnel can be made to have on thick and heavy insulating glove and remain to easily turn screw；4th, telescopic arm
It is makrolon material, with certain toughness, the length of telescopic arm can be adjusted, the answering according to scene during use
The length of telescopic arm is adjusted with environment, the flexibility of operation is improve.
Brief description of the drawings
Fig. 1 is structure schematic front view of the invention.
In figure：1st, buckle；2nd, trip bolt；3rd, telescopic arm；4th, insulation arm；5th, insulation board；6th, through hole；7th, insulating bar；8、
Wing nut；9th, insulation spacer；10th, support column；11st, insulate grab.
Specific embodiment
Reference picture 1 makes the present invention.A kind of fuse switch lead fixed mount, including trip bolt 2, insulation board 5
With wing nut 8, it is characterised in that：The two ends of described insulation board 5 are symmetrically fixed with insulation arm 4, the free end of insulation arm 4
Be arranged with telescopic arm 3, telescopic arm 3 is provided with the trip bolt 2 of threaded connection, trip bolt 2 through the screw on telescopic arm 3 with
Insulation arm 4 is contacted, and telescopic arm 3 is fixed on insulation arm 4, so as to the applied environment regulation telescopic arm 3 according to scene and absolutely
The total length of edge arm 4, the outer end of telescopic arm 3 is fixed with buckle 1, and the free end of buckle 1 is provided with Duckbill type opening, will draw
Line is fixed in Duckbill type opening, and insulation board 5 is provided with the through hole 6 of the strip consistent with the axis direction of insulation board 5, insulating bar
7 one end is fixed with insulation grab 11, the other end of insulating bar 7 through after the through hole 6 on insulation board 5 with the spiral shell of wing nut 8
Line is connected, and support column 10 is held within the outer wall of insulation board 5 immediately below through hole 6, two buckles 1, insulation grab 11 and branch
Dagger 10 is all located at the same side of insulation board 5.
The insulation spacer 9 being set on insulating bar 7 is provided between described insulation board 5 and wing nut 8.
Described buckle 1, trip bolt 2, insulation arm 4, insulation board 5, insulating bar 7, wing nut 8, insulation spacer 9, branch
