Description
Technical field
The invention belongs to 10kV livewire work fields, more particularly to a kind of L-type self-locking drop-proof earthing clamp.
Background technology
As China's power transmission and transformation are fast-developing, construction technology is increasingly standardized, scientific and technicalization, the equipment used
Also it is increasingly advanced.Tentatively electric power lineman is made mainly using portable short-circuit grounding wire as the equipment short circuit grounding of having had a power failure
Safety apparatus, it is the remaining electric charge having a power failure on equipment of releasing that it, which is acted on, the liter of limitation equipment above earth potential in unexpected incoming call
Height, so as to protect staff from danger.Traditional ground wire hitching instrument uses operating rod type, with China's extra-high voltage technology
Application, the increase of shaft tower setting-out true molded dimension, the also corresponding circuit for increasing, being matched with this of distance between cross arm of tower and drainage thread
Conventional insulation bar type length, weight also accordingly increase；When being mounted on tower, operating rod type mounts instrument at mounting point distance, angle
Degree etc. has many restrictions.Conventional insulator rope throws hanging wire clamp tool and has that installation accuracy is low, and mounting is not firm, and dismounting is inconvenient
The problems such as.
The content of the invention
It is an object of the invention to provide a kind of L-type self-locking drop-proof earthing clamp, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the present invention provides a kind of L-type self-locking drop-proof earthing clamp, including self-locking wire clamp, it is described from

Portion region, the self-locking mechanism include upper grab, upper grab stage clip, lower grab, spring catch stage clip, spring catch, ratchet, rack,
Grab tightens up extension spring and rack compression torsion spring；
The upper grab is fixedly connected by upper grab stage clip with left intermediate plate top, described lower snap fit one end and upper grab button
Close, one end that the lower grab other end tightens up extension spring with grab connects, and the grab tightens up the other end and right clamping piece of extension spring
It is fixedly connected；In the middle part of the lower grab and described rack one end is rotatably connected in left intermediate plate bottom by fulcrum respectively, described
Connected in the middle part of lower grab with described rack one end by rack compression torsion spring, the rack other end is provided with hook, the hook
With the ratchet engagement, the ratchet is fixedly connected with spring catch, and the spring catch is fixed on the right side by the spring catch stage clip
Intermediate plate top.
In above-mentioned technical proposal, the L-type self-locking drop-proof earthing clamp also includes insulated wire, suspension ring and ground wire, described
Self-locking wire clamp one end is connected with insulated wire by suspension ring, and the self-locking clip mechanism other end connects with ground wire；The insulation
Line end is fixedly connected with upper clamping hook one end.
In above-mentioned technical proposal, the rack central region, which is provided with, slides duct, and the slip duct sidewall is provided with spacing
Block.
In above-mentioned technical proposal, the right clamping piece is provided with card column, and the card column is connected with rack by sliding duct and sliding
Connect, and fixed with limited block.
