Description
Technical field
It is specifically a kind of steel pipe pole ring flange apparatus for examination and repair the utility model is related to steel pipe pole maintenance field.
Background technology
Steel pipe pole utilization rate in the power transmission network of city is more and more.It is limited by the conditions such as processing, transporting, steel pipe rod segment is most
Big design length control is within 12.0 meters.Each section of steel pipe pole is positioned using ring flange and is fixedly connected with screw, until reaching
To required height.
《Aerial power transmission line Designing Steel Tube Pole technical stipulation（DL/T5130）》" manufacture and installation requirement " chapters and sections in,
Installation suspension centre should be arranged by requiring nothing more than steel pipe pole, and the clip for facilitating construction should be arranged in failed call steel pipe pole.
And hang vertical assembling and maintenance repair work daily, it needs that the flange plate bolt of steel pipe pole is fastened and examined
It looks into.Since flange disk diameter is too big, the human body radius of clean-up is had exceeded, and steel pipe pole itself is without the construction prewelding for supporting to stand
Part so that service personnel can not be fastened and be examined to the flange plate bolt beyond human body operating radius routine by fixed cat ladder
It repaiies, the flange plate bolt for checking and fastening steel pipe pole can not be also removed by conventional pole ascending operation method.
Excessive, safety belt failure that there are bar diameters by investigation, in existing steel pipe pole Inspection, personnel psychology factor,
The normalities influence factor such as operating environment.And because of historical reasons, steel pipe pole continuously improves attachment in the fabrication process so that before
The steel pipe pole of construction without meet personnel overhaul ring flange during personnel's erect-position, indexing iron fitting, lead to day-to-day operation process
In the connection of the bolt of steel pipe pole is not easy to overhaul.
