Description
Technical field
The present invention relates to a kind of earth lead attaching/detaching apparatus.
Background technology
In the equipment maintenance work of transformer station, when equipment or circuit need interruption maintenance, for ensureing the safety of the person and equipment, it is required for after stopping adding hanging earthing conductor or the earthing switch blade that closes on labour equipment carrying out maintenance work.Time length that earth lead hangs, whether smooth directly influence whole operation and can complete in the given time.
Operation used in transformer station and working earthing line at present, mostly use duckbill conductor end, the principle of similar spanner, " stings " copper bar or the cast lead-in wire of firmly rectangle, progressively tightens up duck bill hole by rotation insulating bar and reach the purpose of fixed conductor end with duckbill mouth.Also it is same principle during dismounting earth lead.
The operation of mounting or dismounting earth lead seems and uncomplicated, takes a long time at operation needs.As a example by outdoor 110kV main transformer 10kV bus bridge, skilled person on duty installs a secondary main transformer 10kV side joint ground wire the most at least needs about 10-15 minute time, and the earth lead installing of 220kV then typically requires 20-30 minute.
" technical profession " is not only in the mounting or dismounting of earth lead, is also " muscular labor ", and the earth lead weight that electric pressure is the highest is the biggest, the earth lead of 220kV weighs tens of jin, lifts rear physical demands with several meters of long action bars huge, and is limited by muscle power, operating time is the longest, and failure probability is the biggest.
Summary of the invention
The technical problem to be solved is to provide a kind of device improving ground lead dismounting efficiency, to this end, the present invention provides techniques below scheme:
A kind of earth lead attaching/detaching apparatus, earth lead attaching/detaching apparatus includes sleeve and motor, and described sleeve is made up of inner core, handheld tube, fixing cylinder, and described inner core is lined with elastic insulating layer, and described fixing barrel casing is enclosed within inner core lower outside in inner core upper outside, described handheld tube；Described handheld tube can rotate relative to inner core, has demarcation strip, cuff hoop to be used for tightening sleeve on cartridge exterior in the middle part of described inner core；The head of described motor installs trip gear additional, and after electric machine rotation moment reaches to make earthing clamp head clamping conductor end, motor dallies.
Using on the basis of technique scheme, the present invention also can use technical scheme further below:
Described cuff and fixing cylinder consist of inseparable integral type cuff cylinder.Overall cuff cylinder ease of assembly, if cuff and fixing cylinder are detachable two parts, cuff slides up and down, it is more difficult to hold preferable spacing.
The described hand-held annular groove that is provided with, places ball so that rotating against between handheld tube and inner core is more smooth in described annular groove.
Described fixing cylinder and inner core top have regulation vertical slot, and cylinder and inner core size, the fixed insulation bar that energy is stronger are fixed in the regulation of regulation vertical slot adaptability.
Described motor front end is cross protruding part equipped with electric drill head, described electric drill head, and described demarcation strip upper surface is provided with insulation skid resistant course, and demarcation strip lower surface has the cross recess matched with electric drill head.During operation, one holds motor, and one holds handheld tube, the inner core left-right rotation of manipulation electric drill band moving sleeve, the insulating bar of insulating bar left-right rotation dismounting i.e. simultaneously.
Described cuff includes overlapping cranse and handle, and described set cranse is plugged on handle cam by connector；Button hold together handle, cam high point prop up set cranse can tightening sleeve cranse, pull open handle cam low spot leave set cranse can loosen set cranse.
Owing to using technical scheme, the invention have the benefit that can save dismounting earth lead is expended bodily strength, and effectively controls the time of dismounting earth lead, to shortening the whole operating time, promoting safety management level.

The axonometric chart of a kind of earth lead attaching/detaching apparatus that Fig. 3 provides for the present invention.
Detailed description of the invention
Referring to the drawings, a kind of earth lead attaching/detaching apparatus, earth lead attaching/detaching apparatus includes sleeve and motor 6, described sleeve is made up of inner core 1, handheld tube 2, fixing cylinder 3, described inner core 1 is lined with elastic insulating layer, and described fixing cylinder 3 is enclosed within inner core 1 upper outside, and described handheld tube 2 is enclosed within inner core 1 lower outside；Described handheld tube 2 can rotate relative to inner core 1, has demarcation strip 4, cuff 5 to bind round and be used for tightening sleeve on cartridge exterior in the middle part of described inner core 1.Described elastic insulating layer i.e. serves the effect of insulation, also makes insulating bar have adaptive flexible adjustment in being fixed on sleeve.Rotate the impact to operator's hands in view of insulating bar, make motor 6 rotating speed reduce；Crossing ambassador's earthing clamp in view of motor 6 rotating torques and obtain tension and the problem that causes earth lead chuck to damage, the head of described motor 6 installs trip gear additional, and after motor 6 rotating torque reaches to make earthing clamp head clamping conductor end, motor 6 dallies.
Insulating bar inserts from described inner core 1 top, is lined with elastic insulating layer between described insulating bar and inner core 1, and cuff 5 binds round and makes insulating bar be fastened in sleeve above cartridge exterior.Described cuff 5 consists of inseparable integral type cuff cylinder with fixing cylinder.Overall cuff cylinder ease of assembly, if cuff 5 and fixing cylinder 3 are detachable two parts, cuff slides up and down, it is more difficult to hold preferable spacing.
The described hand-held annular groove 7 that is provided with, places ball so that rotating against between handheld tube and inner core is more smooth in described annular groove.
Stating upper cartridge and have regulation vertical slot, cylinder 3 and inner core 1 size, the fixed insulation bar that energy is stronger are fixed in the regulation of regulation vertical slot adaptability.
Described motor 6 front end is cross protruding part equipped with electric drill head, described electric drill head, and described demarcation strip 4 upper surface is provided with insulation skid resistant course, and demarcation strip lower surface has the groove matched with electric drill head.During operation, one holds motor 6, and one holds handheld tube 2, the inner core left-right rotation of manipulation electric drill band moving sleeve, the insulating bar of insulating bar left-right rotation dismounting i.e. simultaneously.
Described cuff 5 includes overlapping cranse 51 and handle 52, and described set cranse 51 is plugged on handle cam by connector；Button hold together handle 52, cam high point prop up set cranse 51 can tightening sleeve cranse 51, pull open handle, cam low spot leave set cranse 51 can loosen set cranse 51.
