Double-layer thin-wall steel pipe anti-collision concrete telegraph pole

Abstract

The invention belongs to the technical field of telegraph poles, and particularly relates to a double-layer thin-wall steel pipe anti-collision concrete telegraph pole which comprises a mounting baseand a mounting rod welded to the top of the mounting base. The mounting rod is hollow, the outer side of the joint of the mounting base and the mounting rod is sleeved with a fixing cylinder, the outer surface of the mounting base is rotatably connected with a rotating cylinder, and the outer side of the rotating cylinder is slidably connected with a multi-stage folding cylinder. The multi-stage folding plate is arranged, after an animal impacts the multi-stage folding cylinder, the folding cylinder is folded and the deformation of the multi-stage folding cylinder is buffered; meanwhile, the body of the animal is twisted and moves along the outer edge of the multi-stage folding cylinder, the multistage folding cylinder can be pushed to rotate on the mounting base, rotary force unloading isrealized, and the mounting base is prevented from being knocked down; meanwhile, when the multistage folding cylinder is extruded, the multistage folding cylinder can deform upwards to push the extrusion rod, the extrusion rod pushes the folding plate and unloads force to the folding plate, impact force of the animal can be dispersed and the anti-damage capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of electric poles, in particular to a double-layer thin-walled steel pipe anti-collision concrete electric pole. Background technique [0002] The pole is the pole for the wire. The cross arm is an important part of the pole. It is an angle iron fixed horizontally on the top of the pole, and there is a porcelain bottle on it to support the overhead wire. The function of the cross arm is to install insulators and fittings to support wires and lightning conductors, and to keep them at a certain safe distance according to regulations. [0003] When the existing electric poles are installed in the deep forest, due to the habits of animals, play or fight will occur between animals of the same kind or different kinds. The impact of the utility pole, after a long period of impact, will easily make the utility pole tilt, and in severe cases, the utility pole will break. Buffering and force unloading are performed...
