Description
Technical field
The utility model is related to electric power instrument, more particularly to charged for replacement suspension insulator specific purpose tool.
Background technology
Livewire work does not influence the normal operation of power system, it is not necessary to grid switching operation, it is not required that change power system
The method of operation, high pressure overhead power line livewire work can avoid line maintenance have a power failure, defect elimination have a power failure, increase substantially confession
Electric reliability, meets social production and masses' daily life demand.Livewire work personnel will not only possess the theory of higher level
Knowledge, more to possess abundant practical work experience, the particularly important is to possess carries out science improvement to existing operation equipment
Capacity for technological innovation.
Electric transmission line hot-line changes poor insulator, general to be carried out using equipotential and earth potential working mode, in China
The history of development is longer, and technology is also highly developed, and the reliability to power network serves important function.Received during equipotential live line work
The influence of many factors, one be combinational gap calculation it is more complicated, to be counted respectively for different turriforms, different circuit
Calculate, it is desirable to especially accurate；Two is to be limited by turriform, and in some common-tower double-returns, many circuit compact circuits, the smaller operation of spacing is dangerous
Property is big；Three be need to be more with instrument, program is complicated, take time and effort；Four is to be limited by landform, on rice field, pool, hillside and other places
Side, ground staff's activity space is too small.It is general that suspension insulator, but ground are changed using ground potential method when case above is run into
During current potential operation, during bowl head is dismounted, because remote-controlled operation difficulty is big, and physical demands is big, and the activity duration is long, shadow
Ring the safety and operating efficiency of operating personnel.Therefore, the problem for shortening the earth potential live replacing suspension insulator activity duration should
Transport and give birth to.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of specific purpose tool of charged for replacement suspension insulator,
Shorten the activity duration of earth potential live replacing suspension insulator.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：Earth potential live replacing pendency insulation
Son dismounting bowl head specific purpose tool, including it is provided with the mobile jib in axially hollow chamber and can be in the axially hollow chamber of mobile jib in axial sliding
Push rod, the outer Slideslip of the mobile jib is nested with drive push rod sliding sleeve in axial sliding, and the bottom of the mobile jib is provided with for solid
Location hook that is fixed and lifting suspension insulator bowl head, the bottom of the push rod is provided with wedge, and the wedge is in push rod to downslide
Open suspension insulator and linked up with bowl head by wedge surface top when dynamic and disengage, being provided between the bottom and mobile jib bottom of the push rod makes
Push rod realizes the back-moving spring for resetting.
Preferably, the push rod is provided with the set bar being inserted radially into, the mobile jib is correspondingly provided with for being glided on set bar
Dynamic upper hopper chute, the two ends of the set bar are connected with sliding sleeve.
Preferably, the bottom of the mobile jib is provided with the gliding groove for being passed for wedge and being slided up and down.
Preferably, the location hook is connected with fixed cover, the fixed cover nesting is fixed on the bottom of mobile jib.
The technical solution adopted in the utility model, when using, is first stuck in suspension insulator bowl head lower end, by bowl by location hook
Head lifts, and bulb is unclamped with bowl head, then, pushes down on push rod so that open near the insulation of wire first piece on lower end wedge top
Son so that the insulator pin is deviate from front from bowl.Therefore, it can more time saving, labour-saving mode and dismount a bowl head, so as to shorten ground
The current potential charged for replacement suspension insulator activity duration so that livewire work more efficiency and safety.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and detailed description：
Fig. 1 is structural representation when lifting bowl head using the utility model；
Fig. 2 be using the utility model by insulator pin from bowl deviate from front when structural representation.
Specific embodiment
As depicted in figs. 1 and 2, earth potential live replacing suspension insulator dismounting bowl head specific purpose tool 1, for charged for replacement
Suspension insulator 2.Including being provided with the mobile jib 11 in axially hollow chamber and push rod 12 in axial sliding in the axially hollow chamber of mobile jib,
The outer Slideslip of the mobile jib is nested with drive push rod sliding sleeve 13 in axial sliding, and the bottom of the mobile jib is provided with for fixing
And lift the location hook 15 of suspension insulator bowl first 21, the bottom of the push rod is provided with wedge 14, the wedge push rod to
Open suspension insulator and linked up with bowl head by wedge surface top during lower slider and disengage, set between the bottom and mobile jib bottom of the push rod
Having makes push rod realize the back-moving spring 16 for resetting.
Wherein, the push rod is provided with the set bar 121 being inserted radially into, and the mobile jib is correspondingly provided with and is slided up and down for set bar
Upper hopper chute 111, the two ends of the set bar are connected with sliding sleeve.
The bottom of the mobile jib is provided with the gliding groove 112 for being passed for wedge and being slided up and down.The location hook is connected with solid
Surely 151 are covered, the fixed cover is nested in the bottom of mobile jib, the fixed screw screwed in by radial direction is fixed.
As shown in figure 1, when using, location hook 15 is first stuck in insulator bowl head lower end, bowl first 21 is lifted, make bulb with
Bowl head unclamps.As shown in Fig. 2 secondly, pushing down on push rod 12 so that the top of lower end wedge 14 is opened near wire first insulator,
So that the insulator pin is deviate from front from bowl.
