Description
Technical field
The present invention relates to a kind of electric power operation tools, more specifically, it relates to a kind of lead overhead device.
Background technology
Livewire work project to be to overlap and remove based on lead at present, wherein the operation skill of insulating bar working system overlap joint lead
Art difficulty is big, height is required to the professional qualities of staff, in addition to masterful technique to be had and strong awareness of safety, operation people
Member must also have good physical ability situation.The band electrical bonding lead operation of insulating bar working system belongs to common operation, labor intensity compared with
Greatly, especially climbers pole ascending operation when, arm, waist, cervical vertebra long-time stress, operating personnel be easy fatigue.Fastening on wire clamp
Fastening seat during bolt rotation lock between clamping screw and wire clamp easily rotates, and needs repetitive operation that could will fasten several times
Bolt is low very well to be tightened, and operation difficulty and labor intensity are increased.
Chinese patent notification number CN205692991U discloses a kind of livewire work parallel groove clamp tool for fastening/disengaging, including insulation
The body of rod, retaining clip, fixed frame and ambulatory splint are provided with first support and second support, retaining clip setting on fixed frame
In one end of the insulation body of rod, fixed mount setting is on retaining clip, and ambulatory splint one end is connect with first support, ambulatory splint
The other end is connect with second support, and ambulatory splint forms the clamping part for object to be fixed to be clamped with first support, second support.
Staff can carry out live lead clamping plate using the tool for fastening/disengaging, can only be close by band electric car when overcoming traditional operation
Live wire carries out overlapped mode of operation by hand, operation more safe ready.But it can only once load and unload a wire clamp, phase
Distance is not easy to determine between adjacent two wire clamps, and wire clamp handling are inconvenient, labor intensity is big, and lead frame do-nothing operation is time-consuming and laborious, lead lock
It is tightly ineffective easily the risk to fall off occur.
Invention content
The present invention overcomes a wire clamp, adjacent two wire clamp can only be once loaded and unloaded in livewire work gage lap operating process
Between distance be not easy to determine, wire clamp handling are inconvenient, labor intensity is big, and lead frame do-nothing operation is time-consuming and laborious, and lead locking effect is not
It is good easily the deficiency of the risk to fall off occur, a kind of lead overhead device is provided, one in livewire work gage lap operating process
Secondary to load and unload two wire clamps, distance controlling is convenient between adjacent two wire clamp, and wire clamp handling are convenient, greatly reduce labor intensity,
Lead frame do-nothing operation is more time saving and energy saving, and lead locking effect is not in the risk to fall off well.
In order to solve the above-mentioned technical problem, the present invention uses following technical scheme：A kind of livewire work gage lap device,
It is characterized in that including strap, push clamping plate, mounting base is connected on strap, insulating bar connector is connected in mounting base,
Clamping plate is pushed to can be slidably mounted on strap, be rotatably connected wedge in mounting base, and check lock lever, check lock lever are connected on wedge
Through strap, locking boom end is rotatablely connected handle, and eccentric locking disc, eccentric lock are equipped with check lock lever connecting pin on handle
Tight disk is connected on strap, and connection limit lockable mechanism, wedge are equipped with strip between eccentric locking disc and strap
Shape locks clip slot, and on strap and locking clip slot relative position is equipped with several pressing plates, and the surface of pressing plate towards locking clip slot is in
Concave arc structure installs lead between pressing plate and locking clip slot, and the both sides of wedge are equipped with vertically arranged wire clamp catch, pressure
The both sides of seat push the positioning clip slot constituted between clamping plate and strap for clamping wire clamp, position hookup wire in clip slot
Folder, wire clamp are connected on lead, and wire clamp side is fitted on wire clamp catch.
Lead overhead device by lead in use, stretch clamping between pressing plate and locking clip slot, then swing handle, band
Lead is locked at pressing plate and locking is pressed from both sides by dynamic eccentric locking disc rotation to make check lock lever that wedge be pulled to be moved to pressing plate direction
Between slot.Two wire clamps are connected on lead again, two wire clamps distinguish positioning and plug-in mounting in two positioning clip slots, tight on wire clamp at this time
