Background technology
With the growth of supply load and being stepped up for transformer station, the erection task of transmission line of electricity is increasingly heavier.In day
In normal real work, when discovery group founds 35-110kV steel towers, because tower material is little, construction uses the direct pull tower material of manpower substantially
Mode to carry out group vertical, certain potential safety hazard be present and needs take a substantial amount of time and manpower, according to inner suspended holding pole
Group vertical rod tower, pole own wt is larger and assembling is complex, and uncomfortable charge-coupled vertical trourelle uses.According to statistics, annual Yiling District
Because a variety of causes such as overhaul technological transformation, maintenance, repairing need to organize the vertical complementary basis of 35-110kV steel towers 200, each construction task all along with
Security risk, it is extremely urgent to change the vertical steel tower instrument of traditional group.
Currently used method has following two：
Method one：Directly first iron tower main material is pulled up by workmen, used after fixing as pole, is recurred
Hang other main materials and oblique material.
The method shortcoming is：（1）Personnel station is used, existed in platform top, the low height of hanging of safety belt when lifting iron tower main material
Potential safety hazard；（2）Main material is drawn with manpower by two people on tower entirely, consuming strength is big, and main material is without fall arrest measure；（3）Assembling master
Screw is alignd by manpower during material, taken time and effort.
Method two：Organize vertical inner suspended holding pole inside steel tower, recycling, which is twisted, draws high tower material that to carry out group vertical.
The method shortcoming is：（1）Inner suspended holding pole assembly and disassembly is complicated, and ground coordinates personnel more；（2）Inner suspended holding
Bar is used for group and founds large-scale steel tower, and below 110kV tower erections are wasted one's talent on a petty job；（3）Inner suspended holding pole cost is higher.
