This retaining device, when realizing clamping when moving upward under the promotion of second connecting rod at insulating bar, this dynamic device can loosen to prevent clamp by auto lock.When needs unclamp, only need the ratchet pushing retaining device with insulating bar aside.
The jockey be connected with insulating bar that second connecting rod is arranged is for become cylindrical-shaped structure by this jockey, also include transition spool piece, the outer peripheral face of this transition spool piece is provided with step surface, utilize this step surface can be enclosed within insulating bar by transition spool piece, the end face that exposes of transition spool piece is ladder end face, the inner chamber of transition spool piece is arranged to shoulder hole, macropore is positioned at exposed junction, aperture is towards insulating bar, the aperture of the cylindrical-shaped structure of the jockey on the aperture of aperture and second connecting rod matches, described macropore can hold the press-side of ratchet on second connecting rod.
The second connecting rod of this structure matches with insulating bar, can directly utilize insulating bar to operate second connecting rod and retaining device simultaneously, cylindrical-shaped structure on second connecting rod is snapped in the aperture of transition spool piece, and make the press-side of ratchet on second connecting rod be positioned at the macropore of transition spool piece, when upwardly insulating bar, insulating bar promotes second connecting rod and moves upward while ratchet is pushed away ratchet, thus drive six-bar mechanism motion to realize clamping, when needs unclamp, only need pressing insulating bar downwards.
The jockey be connected with insulating bar arranged below the jockey be connected with insulating bar that second connecting rod is arranged and contiguous block is screw connection structure or grafting formula structure.
In sum, the present invention's following advantage compared to existing technology:
High-voltage grounding wire automatic clamping device of the present invention, possesses the ground wire structure of improvement, can adapt to the requirement from 400V low pressure to 10kV high-pressure system.Ground wire clamp operation method is simple, no longer adopts traditional rotation clamping mode, greatly can reduce hand labor intensity, alleviate personnel's burden.The clamping torque of standard is provided, ground wire is installed and whether is firmly no longer determined by operator's muscle power, ensure ground wire installation specification.Lightweight, be easy to carry, and install electroscope in end, when alive circuit, electroscope is by warning reminding, improves fail safe.
Novel connecting ground wire automatic clamping device can reduce the labour intensity of operations staff when installing ground wire greatly, alleviates personnel's burden, can provide enough effective clamping torque simultaneously, ground wire specification is installed.Greatly reducing the labour intensity of operations staff when installing ground wire simultaneously, alleviating personnel's burden, increasing work efficiency.
The ground wire structure improved can make the scope of application of ground wire wider, saves overlapping investment; Earth connection automatic clamping device can reduce the labour intensity of operations staff when installing ground wire greatly, alleviates personnel's burden, can provide enough effective clamping torque simultaneously, ground wire specification is installed.
