2, the stretching device comprises the suitable nut and the bolt sleeve of hollow; Tightrope is located in bolt sleeve inside; Can regulate the tightness of stull and terraced waist through the length of fit that changes bolt sleeve and nut; When bolt sleeve and nut length of fit the most for a long time, tightrope is the most lax, can be used as rope ladder and uses; When bolt sleeve and nut length of fit the most after a little while, tightrope stretches tight the most tightly, when promptly bolt sleeve and nut extended length were the longest, stull and terraced waist were pushed up the most tightly, can be used as hard ladder and used.
3, in stull topmost, be provided with hook, be convenient to mount, during use, be articulated on lead or other equipment through hook; The following node bottom of tightrope is provided with base for supporting, is used to support superstructure.
4, insulating ladder waist two ends offer draw-in groove, and the insulation stull is installed in the draw-in groove; Insulation stull two ends are provided with the silk rope that runs through insulation stull and insulating ladder waist; Silk rope upper end is equipped with the last node that is stuck in the insulation stull topmost; Silk rope lower end is equipped with down node, is provided with the stretching device between following node and the insulation stull bottom, and is simple in structure; Avoid staff's health charged, safe and reliable; Easy to use, labour intensity is low; It is little to take up room, and is easy to carry, and is convenient to deposit.
5, the stretching device comprises the suitable nut and the bolt sleeve of hollow; The silk rope is located in bolt sleeve inside; Can regulate the tightness of insulation stull and insulating ladder waist through the length of fit that changes bolt sleeve and nut; When bolt sleeve and nut length of fit the most for a long time, the silk rope is the most lax, can be used as rope ladder and uses; When bolt sleeve and nut length of fit the most after a little while, the silk rope stretches tight the most tightly, when promptly bolt sleeve and nut extended length were the longest, the insulation stull was pushed up the most tightly with the insulating ladder waist, can be used as hard terraced use.
6, in insulation stull topmost, be provided with link, be convenient to mount, during use, be articulated on lead or other equipment, prevent to thread off through link, safe and reliable; The following node bottom of silk rope is provided with base for supporting, is used to support superstructure.
