[0010] specific embodiment
A kind of steel tower integral hoisting angle steel jig of the present utility model, this steel tower integral hoisting angle steel jig is comprised of upper card assembly 1, lower card assembly 3, movable bolt 2, clevis eye 4, upper card assembly 1, lower card assembly 3 parts adopt welding to form, and are provided with 4 movable bolts that are arranged symmetrically with 2; Be fixed by bolts on card assembly 1, on upper and lower card assembly, correspondence position is open slot, by movable bolt 2, connects upper and lower card assembly; On upper card assembly, be provided with a rotating shaft 5, can, at flexible rotating within the scope of 180 ° of levels, a bolt hole be set in the middle of rotating shaft 5 and connect clevis eye 4.
The upper and lower card assembly surface of described a kind of steel tower integral hoisting angle steel jig arranges respectively MC nylon lining, zinc-plated for the protection of steel tower.
During use, be arranged on iron tower main material angle steel, utilize 4 movable bolts that are arranged symmetrically with to connect upper and lower card assembly.
For guaranteeing to swing in steel tower integral lifting process, cause steel tower integral hoisting angle steel jig to be subject to force direction inconsistent with design, it on, block on assembly a rotating shaft is set, can be at flexible rotating within the scope of 180 ° of levels.In the middle of rotating shaft, a bolt hole is set, is used for connecting clevis eye.Clevis eye is flexible rotating in the vertical direction, thereby has realized freely rotating between upper and lower, left and right.
For the zinc coating of protection iron tower main material, the upper and lower card assembly surface of steel tower integral hoisting angle steel jig arranges respectively MC nylon lining.Not only can protect zinc layer but also can play to sliding effect.
Convenient when applying at the scene, avoid repeated disassembled and assembled bolt, steel tower integral hoisting angle steel jig is to be fixed by bolts on upper card assembly with 4 movable bolts, on upper and lower card assembly, correspondence position is open slot.
Above-mentioned a kind of steel tower integral hoisting angle steel jig, is all to adopt steel material to make, and safety factor is more than 2.5 times.Can according to circuit, lift weight and the main material specification size of steel tower, be processed into the steel tower integral hoisting angle steel jig of different operating load.
The utility model is being used four symmetrical steel tower integral hoisting angle steel jigs of the reliable installation of main angle iron position inside principal post and crosspiece hinge-point.Clevis eye is towards crane direction in place, less if cross-arm angle steel Hoisting Position intersects iron, and during the stressed demand that can not meet integral hoisting, cross-arm is taked reinforcement measure.During installation, upper card assembly 1 is placed on to angle steel outside, lower card assembly 3 is placed on angle steel inner side, with movable bolt 2, connects upper and lower card assembly, and fastening nut above it, is connected firmly upper and lower card assembly.Lifting steel rope is connected in rotating shaft to 5 with clevis eye 4.
