Abstract
The utility model belongs to the field of devices for a power grid, and particularly relates to an insulating cross arm. The insulating cross arm comprises a supporting rod, an adjusting arm, connectors and insulating cross arm bodies, wherein two bolts are arranged on the supporting rod and are arranged oppositely, the adjusting arm is connected with the bolts through adjusting nuts, the adjusting arm is movably connected with the adjusting nuts through bolt pins, the two insulating cross arm bodies are movably connected with the connectors, an oil cylinder is arranged on the supporting rod and fixed into the supporting rod, and the end portions of a cylinder rod of the oil cylinder are fixedly connected with the connectors. The insulating cross arm has the advantages that ejecting, pushing and fixing are achieved mainly through the oil cylinder, the bolts and the nuts are matched to conduct adjustment and supporting, hot-line work can be achieved, the safety coefficient is increased, and automatic control is achieved.
Description
Technical field
The utility model belongs to electrical network apparatus field, specifically a kind of insulator crossarm.
Background technology
At present ，Guo Wang company to the requirement of power supply reliability progressively improve ，Dui power supply enterprise to client's service standard, require also more and more stricter, and reduce user have a power failure area, reduce customer outage hours etc. the most feasible mode carry out exactly livewire work.Livewire work is that with high content of technology, a safe skill requires strictly, and the line maintenance method of remarkable in economical benefits.By to the research of livewire work Method and kit for and improvement, to improving livewire work efficiency, expand charged job area undoubtedly, can play good effect.General suburb is with a varied topography compared with urban district, and many charged work job site is subject to the impact insulation of landform to tremble arm car cannot be close, can not implement medial potential working, thereby often adopt earth potential working method to carry out charged work.And the lifting of the charged insulating cross-arm using is now partly to take rope band as traction, the wire that is difficult to sling, power tool is heavy in addition, has increased the weight of operating personnel's labour intensity.
Summary of the invention
The utility model, for the weak point existing in above-mentioned technology, proposes a kind of insulator crossarm.
The utility model provides following technical scheme:
Insulator crossarm, it comprises support bar, regulating arm, connector, insulator crossarm arm, on support bar, be provided with two screw rods, screw rod arranges on the contrary, and regulating arm is connected with screw rod by adjusting nut, between regulating arm and adjusting nut, by pin, is flexibly connected, two bar insulation cross-arm arms are flexibly connected with connector, in support bar, be provided with an oil cylinder, oil cylinder is fixed in support bar, and the cylinder boom end of oil cylinder is fixedly connected with connector.
On described insulator crossarm arm, be provided with several portable annular groove connectors.
On described support bar, be provided with fixedly buckle, fixed card is buckled and is provided with fixedly chain.
The utility model has the advantages that and adopted oil cylinder pushing tow to be fixed as master, then coordinate and regulate support by bolt and nut, reach energy livewire work, improved safety factor, realized automatic control.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
