Description
Technical field
The present invention relates to a kind of power supply company's power distribution live-wire ancillary equipments, belong to power distribution live-wire field, specifically
It is a kind of fuse switch lead fixed frame that ground, which is said,.
Background technique
In the routine work of power supply company, charged for replacement fuse switch belongs to 33 classes of power distribution live-wire development
One of events in operation, replacing fuse switch at present, there are mainly three types of handling situations: one is directly cutting drop type fusing
The upper end power supply of device, then replaces fuse switch；Another kind is the upper end electrification of fuse switch, deactivates lower end load
After replace fuse switch；There are also one is on-loads to replace fuse switch.Three kinds of above-mentioned situations, fall in replacement
It when formula fuse, requires first to tie the upper lead of fuse switch on main line with insulation fall prevention rope, lower lead insulation
Fall prevention rope ties on cross-arm.In the fixation procedure of upper lead, first fall prevention rope to be tied on main line by insulation bucket, due to leading
Line phase spacing is closer, is easy to encounter conducting wire or nearby device during mobile insulation bucket, increases the danger of operation
Property.Moving up and down for insulation bucket, virtually expands job area, increases the labor intensity of operating personnel.And lead quilt
It has been tied up to above main line and cross-arm respectively, they are in a kind of suspended state, in wind or in the case where accidentally touch, it is easy to
The shaking of lead is caused, if lead masking is not talked about sternly, very big security risk can be brought to livewire work.
Summary of the invention
It is simple, easy to use that the purpose of the present invention is to provide a kind of structures, does not need in operation process anti-using insulation
Upper and lower lead fixation can be effectively prevented from the swing of lead by pendant rope, and the drop type for improving live-working safety is molten
Disconnected device lead fixed frame.
In order to reach the goals above, the technical scheme adopted by the invention is that: a kind of fuse switch lead is fixed
Frame, including fastening screw, insulation board and wing nut, it is characterised in that: the both ends of the insulation board are symmetrically fixed with absolutely
Edge arm, the free end of insulation arm are arranged with telescopic arm, and telescopic arm is equipped with the fastening screw being threadedly coupled, and fastening screw, which passes through, to be stretched
Screw hole and insulation arm contact, the outer end of telescopic arm on contracting arm are fixed with buckle, and the free end of buckle is opened equipped with Duckbill type
Mouthful, lead is fixed in Duckbill type opening, insulation board is equipped with the through-hole with the consistent strip of insulation board axis direction,
One end of insulating bar is fixed with insulation grab, the other end of insulating bar pass through after the through-hole on insulation board with wing nut screw thread
Connection, support column are fixed on the insulation board outer wall immediately below through-hole, and two buckles, insulation grab and support column are all located at
The same side of insulation board.
The insulation spacer being set on insulating bar is equipped between the insulation board and wing nut.
The buckle, fastening screw, insulation arm, insulation board, insulating bar, wing nut, insulation spacer, support column and absolutely
Edge grab is epoxy resin material, and the telescopic arm is polycarbonate material.
The upper end of the fastening screw is fixed with handle.
The beneficial effects of the present invention are: 1, in charged for replacement fuse switch, do not need to move insulation bucket again
System's insulation fall prevention rope, reduces the moving range for the bucket that insulate in operation, simplifies the process of charged for replacement fuse switch, drop
The low labor intensity of operating personnel；2, the position of insulating bar in through-holes is adjusted according to the actual size of cross-arm, passes through insulation
Grab and the support column mating reaction being fixed on insulation board, insulation board is securely fixed on cross-arm；3, on fastening screw
Face is fixed with handle, and livewire work personnel can be made to have on thick and heavy insulating glove and remain to easily turn screw；4, telescopic arm
For polycarbonate material, there is certain toughness, the length of telescopic arm is adjustable, during use answering according to scene
The length that telescopic arm is adjusted with environment, improves the flexibility of operation.
Detailed description of the invention
Fig. 1 is structure of the main view of the invention.
In figure: 1, buckling；2, fastening screw；3, telescopic arm；4, insulation arm；5, insulation board；6, through-hole；7, insulating bar；8,
Wing nut；9, insulation spacer；10, support column；11, insulate grab.
Specific embodiment
The production present invention referring to Fig.1.A kind of fuse switch lead fixed frame, including fastening screw 2, insulation board 5
With wing nut 8, it is characterised in that: the both ends of the 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 equipped with the fastening screw 2 being threadedly coupled, fastening screw 2 pass through screw hole on telescopic arm 3 with
Insulation arm 4 contacts, and telescopic arm 3 is fixed on insulation arm 4, thus according to the application environment at scene adjusting telescopic arm 3 and absolutely
The total length of edge arm 4, the outer end of telescopic arm 3 are fixed with buckle 1, buckle 1 free end and are open equipped with Duckbill type, will draw
Line is fixed in Duckbill type opening, and insulation board 5 is equipped with the through-hole 6 with the consistent strip of 5 axis direction of insulation board, insulating bar
7 one end is fixed with insulation grab 11, the other end of insulating bar 7 pass through after the through-hole 6 on insulation board 5 with 8 spiral shell of wing nut
Line connection, support column 10 are fixed on 5 outer wall of insulation board 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 equipped between the insulation board 5 and wing nut 8.
The buckle 1, fastening screw 2, insulation arm 4, insulation board 5, insulating bar 7, wing nut 8, insulation spacer 9, branch
Dagger 10 and insulation grab 11 are epoxy resin material, and the telescopic arm 3 is polycarbonate material.
The upper end of the fastening screw 2 is fixed with handle.
Using the present invention in charged for replacement fuse switch, operating personnel is adjusted according to the actual size of cross-arm first
Position of the insulating bar 7 in the through-hole 6 of strip, make insulate grab 11 flat segments and support column 10 be clamped in cross-arm it is upper,
Lower wall, the crotch section and insulation board 5 of the grab 11 that insulate are clamped in the left and right wall of cross-arm, and rotation wing nut 8 tenses insulation grab
11, so that insulation board 5 be made to be firmly secured on cross-arm；Then position of the adjustment telescopic arm 3 on insulation arm 4, according to scene
Use environment determines the length that buckle 1 stretches out, and rotational fastener screw 2 fastens telescopic arm 3 and insulation arm 4, removes to be replaced fall
After falling the upper and lower lead of formula fuse, it is pushed into the Duckbill type opening of corresponding upper and lower two buckles 1 respectively, it will with insulated target
After the present invention and cross-arm wrap up, then carry out charged for replacement fuse switch.Using the present invention, can substitute over use it is exhausted
Edge fall prevention rope does not need to move again to insulate to struggle against and goes to be insulation fall prevention rope, reduces the moving range for the bucket that insulate in operation, reduce
The labor intensity of operating personnel simplifies the process of charged for replacement fuse switch, shortens the livewire work time.
