Description
Technical field
The invention belongs to field of electricity construction, is related to high-altitude Setting-out Technique between steel tower, especially a kind of transmission line of electricity unwrapping wire
Guide rope of constructing divides rope technique.
Background technology
At present, transmission line construction technique is that laying type unfolds pull rope, is easily disturbed in work progress by external coordination, then enter
Row one leads four band pull ropes, unfolding process and needs to use tension pay-off machine during coaster of point restricting and steel tower all needs step by step
More than 2 are twisted progress.
By retrieving, the patent document of following analogous technical fields is found：
" one leads two " unfolding construction technologies (CN102593759A) to a kind of large-section lead, it is characterised in that including following step
Suddenly：1., preparation of construction：Enter row conductor, the crimping experiment of ground wire, setting tension field and traction field place, cleaning construction passage；
2., suspension coaster；3., crossing construction；4., tension stringing, unfolding ground wire, wire, face anchor in time；5., crimping lead wire, carry out tight
Line, observation sag, hanging wire, complete whole construction.This invention ensures that having identical laying tension with mutually each sub-conductor, ensure that
Poling Construction quality；And optimize wire winding pulley suspension, wire messenger and pull rope unfolding, unfolding conductor, stringing, annex peace
The construction technologies such as dress, effectively improve tension stringing efficiency of construction；Manpower, waste of time are reduced, and needs number of devices
Few, floor space is small, has higher social economy's property.
A kind of laying tension machine actuation means (CN203269220U), there is the remote control of control laying tension machine running
Case, remote control case is connected with the relay on all laying tension machines simultaneously, by the control system of remote control case to each
Laying tension machine is controlled, and is only needed one can manipulate more machines simultaneously, is reduced personnel cost；Meanwhile one man operation keeps away
Exempt from difficult and trouble caused by more people's cooperations.There is larger distance between remote control case and laying tension machine, on the one hand can keep away
Exempt from huge noise and a large amount of dusts caused by by laying tension machine, avoid the health of operating personnel from being affected；On the other hand, grasp
Make personnel suitable distance may be selected to be manipulated, sight will not be because hindered by laying tension machine, and the operator that is more convenient for
Observation and control of the member to payingoff construction scene.
Comparative analysis, compared with the application technology contents claimed, it is wanted above disclosed prior art
Relatively big difference be present in the technical problem of solution, the technological means used.
The content of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, there is provided a kind of simple in construction, reasonable in design, use
Convenient, process transmission line of electricity payingoff construction guide rope point rope technique.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of transmission line of electricity payingoff construction guide rope point rope technique, it is characterised in that：All construction is all carried out in high-altitude, i.e.,
Separated time construction is carried out on tower, Specific construction technique is as follows：
(1) steel tower is arranged according to separated time construction technology, Lever Blocks is installed in the upper center of steel tower 1, outside steel tower upper end
Lifting block is lifted with along position, Lever Blocks is connected with a releasing pulley, Lever Blocks control unwrapping wire by the lifting block
Coaster moves up and down；
Pull rope is coated with releasing pulley, the front end of the traction limp of one end connection one of the pull rope, the pull rope
The direction of from the other end to cable to be laid extend and be connected to the pulling equipment for drawing take-up；Between the rear end for drawing limp
Every uniformly connecting a plurality of guide rope,
Interval is provided with multiple upturned tackles on steel tower corresponding to releasing pulley obliquely downward, upturned tackle is used for spacing branch
Guide rope is supportted, upturned tackle corresponds with guide rope, can need to increase and decrease the quantity of upturned tackle according to construction；
Guide rope earthward extends, and is connected to cable, and guide rope traction cable advances, and cable, which is drawn, to be risen on steel tower
It is and spacing in upturned tackle；
(2) releasing pulley declines, and Lever Blocks operation loosens downwards releasing pulley, and releasing pulley declines until tow out
The height of plate is less than upturned tackle, and now the weight of guide rope is pressed in upturned tackle, and guide rope laterally pulls traction limp, leads
Carrying-off plate is tilted gradually by original vertical Hoisting Position, and releasing pulley declines process and remained a constant speed stably；
(3) traction is advanced, and releasing pulley lower end hook is opened, and releasing pulley departs from traction limp, and starting pulling equipment makes
Pull rope pulls traction limp transverse shifting；
Pulling equipment continuous firing, pull rope drive traction limp, and tow out strip moves a plurality of guiding line locking to waiting to apply
Next steel tower movement in work direction；
(4) draw limp and reach next steel tower position, the front end of the releasing pulley mounting traction limp on next steel tower
Then rise to the initial position (1) up to step, repeat the above steps (1) to step (3), steel tower is constructed step by step, by guide rope
Automatic split is placed in corresponding cable installation site, is constructed and is carried out continuously in the air in height.
Moreover, limp is drawn in the technique draws limp using light-duty guide rope made of lightweight, heat-resistant insulation material,
Guide rope point is separately customized to different colours.
Moreover, the traction limp connects four guide ropes, guide rope is using lightweight, heat-resisting, insulation guide rope.
The advantages and positive effects of the present invention are：
1st, this technique is incorporated into the opening and closing technique of releasing pulley, realizes in the case where avoiding using machinery, by guide rope
Split in each releasing pulley.
2nd, all construction is all carried out this technique in high-altitude, is greatly avoided external coordination interference, is significantly shortened the unwrapping wire duration.
3rd, this technique saves the mechanical usage quantity of big machinery and each steel tower, and effect is extremely obvious.
4th, this technique saves the input of workmen work high above the ground personnel, reduces work high above the ground risk, strengthens constructor
The security of member.
5th, lightweight of this technique due to use, heat-resisting, insulation guide rope, in work progress, personal safety and unexpected break
Substantially reduced etc. danger degree.
6th, transmission line of electricity payingoff construction guide rope of the present invention divides rope process reform traditional unwrapping wire technique, will originally divide rope
It is that pull rope is changed to lightweight, high temperature insulation rope carries out a point rope, then enters row conductor traction by being replaced into pull rope respectively, reduction is applied
Work is to tension pay-off machine and the usage quantity of equipment such as is twisted, and simplifies construction procedure, reduces construction cost, lifting construction efficiency.
