Description
Technical field
The present invention relates to a kind of automatic trip vertical posts hanging method and special hanger, belong to technical field of electrical network construction.
Background technology
In electrical network construction, vertical posts adopts individual wire rope sling, and during pole erecting, electric pole can not vertically erect, and must enter bar hole at a slant, and electric pole stands well also to be needed longitudinally, laterally to calibrate centering by manpower, and steel wire loop also needs manually to step on bar and trips.There is following problem in background technology: security risk is large, separates sling and need manually step on bar operation, the dangerous point such as there is falling from high altitude, the bar that falls is hurted sb.'s feelings; Vertical rod length consuming time, exist step on that bar is triped, shaft vertically, recalibrate time-consuming link such as 3, bar position etc.; Construction quality is low, and shaft tilts in the vertical again process in position, and shaft can be made camber line along bar base and roll, and unavoidably cross travel occurs, bar position easily occurs relatively large deviation.
Summary of the invention
The object of the invention is to provide a kind of automatic trip vertical posts hanging method and special hanger, replaces individual wire rope sling, suspension rod vertical rod, vertical suspension rod can be realized, accurately enter position, not step on bar and trip, and safe and reliable, simple to operate, of many uses, solve the problems referred to above existed in background technology.
The technical scheme of invention is: automatic trip vertical posts special hanger for hoisting, comprise steady arm, Special sling, suspension hook, pulley buckle release, thread off and restrict and snap close, link together pulley and suspension ring of pulley buckle release are formed, steady arm is cylindric, flexible internal diameter and head of the mast external diameter match, on the excircle of steady arm, 60 degree, interval is provided with two grommets, Special sling is first through a grommet on steady arm, hang over again on suspension hook, and then through another grommet on steady arm, the two ends of Special sling are provided with noose, the two ends of Special sling are combined becomes bifilar hoist cable, bifilar hoist cable and noose are linked together by snap close, one end of dropout rope connects snap close, the other end is through the pulley of pulley buckle release, the suspension ring of pulley buckle release also hang on suspension hook.
Described steady arm is circumferentially provided with multiple dowel bolt, positions the head of the mast; Steady arm is also provided with baffle plate, prevents electric pole from passing steady arm.
Automatic trip vertical posts hanging method, above-mentioned special hanger is used to carry out, comprise following steps: 1. steady arm is arranged on the head of the mast, by Special sling through two grommets on steady arm, and the hoist cable between two grommets is hung on suspension hook, the two ends of Special sling are provided with noose, and the two ends of Special sling are combined becomes bifilar hoist cable, bifilar hoist cable is linked together by snap close with noose after not walking around electric pole; 2. hang on suspension hook by the suspension ring of pulley buckle release, the one end of rope of threading off connects snap close, and the other end is through the pulley of pulley buckle release; 3. lift by crane suspension hook, Special sling becomes the triangle of change, pull-up electric pole, and leg-of-mutton three summits are steady arm, snap close and suspension hook respectively, and along with standing up of electric pole, the extended line of leg-of-mutton suspension hook summit gradually to steady arm, snap close two summit is close; When electric pole is to vertical position, steady arm, snap close and suspension hook are point-blank; 4. after electric pole location, back fill, rope of threading off is pulled on ground, snap close and Special sling are moved along electric pole to the head of the mast, rise suspension hook simultaneously, snap close, Special sling depart from from the head of the mast together with steady arm, steady arm, snap close, Special sling put back to ground with pulley buckle release with suspension hook, do not need to step on bar and trip, and realize separating rope on ground and thread off.
Described steady arm is circumferentially provided with multiple dowel bolt, positions the head of the mast; Steady arm is also provided with baffle plate, and whole steady arm is cap sequence, is buckled in the head of the mast.
Steady arm of the present invention is arranged on the head of the mast when using, and for the angle of fixing Special sling and electric pole, keeps plumbness after electric pole is sling; Special sling is not that isometrical rod-type or taper rod-type limit by electric pole, can live shaft by lock ring safely and reliably, ensures, in suspension rod process, slippage pole collapse accident does not occur.Pulley buckle release and steady arm, Special sling is ingenious coordinates, and realizes separating rope on ground and threads off.
Beneficial effect of the present invention is: risk is low, does not need manually to step on bar and trips, safe and reliable; Vertical rod is fast, reduces links such as stepping on bar is triped, shaft vertical, recalibration bar position, at least saves the time of half; Quality is high, and shaft vertically enters position, is convenient to Measurement and calibration, improves construction quality.
The each parts of the present invention are all by more than 10 tons force design, and rural power grids 15 meters and following electric pole weight are all less than 3 tons, and safety factor is high.Special sling adopts duplex type to overlap the design of single claim-reduction, adds the contact surface of Special sling and shaft, can banding electric pole more firmly.Dropout rope nylon rope, is carried out on ground by pulley buckle release, at utmost reduces the risk of operating personal.Steady arm uses the round steel welding of 8mm plate iron and φ 16, and pot galvanize process, has good durability.Steady arm of the present invention has dowel bolt, can adapt to the cement pole of different-diameter, can be used for the electric pole Overhaul site of most of rural power grids engineering concrete bar camp site and rural area distribution, Applicable scope is very large.
