By adopting technique scheme, the anchor ear device of insulation single ladder body upper end can the horizontal empty such as auto lock concrete pillar, be stuck in firmly on fixture, it is ensured that safety during operation, and simple in construction, easy to operate, safe and reliable.
The present invention is further arranged to: the middle part of described left anchor ear and right anchor ear is arc structure, and left anchor ear and right anchor ear inner surface are provided with multiple keeper. By this setting, keeper can increase the frictional force between anchor ear and fixture, not easily slides, more safe and reliable.
The present invention is further arranged to: described multiple keepers are the raised line being fixedly installed, and described each raised line is serpentine structure. By this setting, the structure of keeper is arranged rationally, works relatively reliable.
The present invention is further arranged to: described steel bushing outer surface is provided with one layer of coatings layer. By this setting, it is possible to prevent operating personnel from unintentionally encountering and getting an electric shock.
The present invention is further arranged to: described left anchor ear, supporter and the uniform steel bar of right anchor ear, installs leakage alarm in the middle part of described supporter. By this setting, left anchor ear, supporter and right anchor ear having during electric leakage and can be rapidly transferred to leakage alarm, leakage alarm can send alarm.
The present invention is further arranged to: two ends, described supporter left and right are symmetrically arranged with contiguous block, the L-shaped structure of described contiguous block, and described contiguous block and supporter are structure as a whole. By this setting, described connecting block structure is arranged rationally.
The present invention is further arranged to: described steel bushing and contiguous block are locked by connecting bolt. By this setting, steel bushing is easy to connect, reliable with contiguous block.
The present invention is further arranged to: be arranged side by side two leakage alarms on described supporter front end face. By this setting, after a leakage alarm is broken, another can normally use, more safe and reliable.
The present invention is further arranged to: in described steel bushing, clamping screw is provided with fixing plate, and described clamping screw promotes the tight montant of fixing plate clamp. By this setting, clamping screw is fixing with single ladder relatively reliable by fixing plate.
The invention have the advantage that compared with prior art, present configuration arranges rationally, anchor ear device is installed in insulation single ladder upper end, this anchor ear device can the horizontal empty such as auto lock concrete pillar, it is stuck in firmly on fixture, it is ensured that safety during operation, and simple in construction, easy to operate, safe and reliable.
Below in conjunction with Figure of description and specific embodiment, the invention will be further described.
