Above-mentioned lightning protection side pin needle body between its first section steel pipe and second section steel pipe are put, adopts between second section steel pipe and the 3rd section steel pipe to be threaded after installation;
Above-mentioned lightning protection side pin needle body between its first section steel pipe and second section steel pipe are put, adopts trip bolt to connect between second section steel pipe and the 3rd section steel pipe after installation;
Between above-mentioned first section steel pipe and second section steel pipe are put, can also adopt built-in being threaded between second section steel pipe and the 3rd section steel pipe, promptly second section steel pipe inserts from an end of first section steel pipe, the other end mouth of pipe place of first section steel pipe establishes internal thread, on second section steel pipe of Pei Heing external screw thread is set with it, same, the 3rd section steel pipe inserts from an end of second section steel pipe, the other end mouth of pipe place of second section steel pipe establishes internal thread, on the 3rd section steel pipe of Pei Heing external screw thread is set with it, during installation, extract out successively to rotate counterclockwise behind second section steel pipe and the 3rd section steel pipe and get final product.
Installation process of the present utility model is as follows:
Lightning protection side pin need be installed in the head of mast, because shaft tower is to be formed by the angle steel overlap joint, at first two clamping plate below the hold-down support substrate are clipped on the horizontal plane of angle steel, hook the edge of angle steel vertical plane then with two fastening bolts that have a gib head, undertaken fastening by bolt again, after hold-down support installed, lightning protection side pin needle body is carried out connection piecemeal.
Compared with prior art, this novel main part adopts telescopic connection, the zinc-plated seamless steel pipe of The selection of pipe, connection between each section and capable of expansion and contraction, proportioning is suitable, process overcurrent and windage yaw, strength checking, the selection of size of pipe and tubing meets the rules requirement, satisfies the requirement of live line working safe distance fully, and rational in infrastructure, convenient transportation, but live line working, a people can implement to install, and is simple, quick, greatly reduce labour intensity, increase work efficiency.
