Detailed description of the invention
See Fig. 1; Supporting in pairs about climbers of the present invention, when operator climbs icing electric pole 12, bipod puts on climbers respectively, utilizes self-lock mechanism to climb electric pole.Using method:
See Fig. 2,3,6; Operator entangles icing electric pole 12 the arc coupler body 2 of right crus of diaphragm button, the right crus of diaphragm of operator enters pedal hole 7, forefoot pedals pedal 9, arc coupler body 2 right low left high is made to tilt to produce leverage by support arm 5, because pedal 9 extends the length of support arm 5, pedaling pedal 9 makes leverage greatly strengthen, and make left briquetting 1 compress on the left of icing electric pole 12, right briquetting 3 compresses on the right side of icing electric pole 12.
The rear heel of operator is had an effect and is pedaled pin and step on flap 8 and make it to rotate clockwise, elastic friction block 11 withstands right briquetting 3 and is close to icing electric pole 12 towards upper left side, prevent arc coupler body 2 from gliding, the body weight of operator is larger, and the adhesion of right crus of diaphragm button and icing electric pole 12 is tighter.Now, left foot button can be buckled square set at right crus of diaphragm and lives on icing electric pole 12 to climb.
See Fig. 2; The right crus of diaphragm of operator is lifted, pin is stepped on flap 8 and is rotated counterclockwise, elastic friction block 11 departs from right briquetting 3 and icing electric pole 12, pin is stepped on flap 8 and is promoted limit stop post 6 and drive on the right side of support arm 5 to move upward, arc coupler body 2 is the level of state and departs from icing electric pole 12, and right crus of diaphragm button can be buckled square set at left foot and live in icing electric pole 12 continuation to climb.Two, left and right climbers are climbed icing electric pole 12 top on taking turns and are overhauled.
See Fig. 2,6: right briquetting 3 is riveted with latch plate 4 is fixing, latch plate 4 right part to insert in arc coupler body 2 and is welded and fixed, this structure makes right briquetting 3 have elasticity, ensure that right briquetting 3 is firmly connected with arc coupler body 2, different angle changes can be adapted to when arc coupler body 2 catches on icing electric pole 12, ensure that right briquetting 3 compresses icing electric pole 12.
Left briquetting 1 and right briquetting 3 are the toothed arc block of inner surface, refer to that the inner surface of arc block is provided with 2-7 toothrow arranged in parallel up and down, the teeth portion of arc block is provided with carburized layer and quenching heat treatment, makes tooth arranged in parallel can pierce through the ice sheet on icing electric pole 12 surface.The tooth of left briquetting 1 and right briquetting 3 inner surface is screw thread form, refer to that left briquetting 1 and right briquetting 3 are one section that scales off from tapped annulus respectively, compared with tooth arranged in parallel, internal thread is the tooth that the pitch of oblique arrangement is greater than 5mm, internal thread not only can pierce through the ice sheet on icing electric pole 12 surface, and that icing electric pole 12 can also be stung is tightlier non-slip.
Arc coupler body 2 of the present invention adopts the seamless steel pipe of medium carbon structural alloy steel, such as 25Mn or 30CrMnSi, not only has good welding performance, also obtains good comprehensive mechanical performance by modifier treatment.Left briquetting 1 and right briquetting 3 adopt alloy carburizing steel, such as 12CrNi3r or 18CrMnTi, threaded portion carburized layer thickness is between 1-1.2mm, retained austenite process is eliminated through quenching---tempering---cryogenic freezing, the matrix hardness of left like this briquetting 1 and right briquetting 3 is between HRB250-300, the hardness of threaded portion, between HRC58-60, uses can not produce low-temperature cracks at cold environment.
