It is bad, fall it.Without carrying out deicing to pylon electric pole etc. again, a large amount of time has been saved.Within the effective working time,
Can high-altitude stringing as much as possible carry out deicing, working efficiency is significantly improved.
The utility model is also safer when practical.In traditional high-altitude stringing deicing operation, staff needs to take
Smooth pylon and electric pole etc. are climbed up with tool, safety rope etc..Wintry weather is cold, staff in scale removal process also only
General cleaning can be carried out to the ice sheet in pylon and electric pole, can not accomplish it is fully erased, especially in winter, these supports
Partial surface is also very smooth, is walked and climbed abnormally dangerous, very easy skidding on its surface.Although safety rope
Protection, but slip and extremely be easy to cause the actual bodily harms such as bump injury, bruise and crush injury.Practical the utility model carries out deicing
When, operator station carries out operation on the ground, has thoroughly prevented the injury that climbing may cause, safer.

The utility model is further described below with reference to actual ice detachment.
The utility model needs to be carried out according to weather forecast and patrol record etc. using when needing deicing region to enter winter
Or weather forecast is whens having large-scale cooling, rain and snow weather etc., it is necessary to handle high-altitude stringing.Because of high-altitude at this time
Stringing, electric pole and pylon etc. freeze not yet, are easy climbing.
Staff connects circuit first before setting out, and battery 10 starts to export electric current.Observation driving motor 23 is at this time
It is no to work normally, it can work normally and then bring it into job location, otherwise maintenance part can be sent to repair.
After staff rushes to repair location, start to work, specific process are as follows: staff is first according to two
The distance between electric pole or pylon and its height calculate the length for needing insulated wire 33, then by the insulated wire of appropriate length
On the 33 online rollers 32 of winding.One staff carries the utility model and climbs up electric pole or pylon, another work people
Member therewith, as Security Officer and observer.Another group of staff climbs in another electric pole or pylon.
After first job personnel climb in electric pole or pylon, the locking nut B65 in lower a pair of of shaft 13 is dismantled,
Then right risers 15 are pulled, contact it no longer with cylindrical section C63.Right risers 15 are divided into three sections of upper, middle and lower, and upper section is under
The middle section Duan Junyu is hinged, and long hole is symmetrically provided on upper section and lower section, and the cylindrical section C63 of shaft 13 passes through locking nut after passing through
B65 and right risers 15, which are realized, to be connected.This spline structure is advantageous in that, puts the utility model when needing to open upper section or lower section
It sets when on the stringing of high-altitude, it is only necessary to two locking nut B65 are removed, it is easy to operate, it is very easy to use.On especially
Section and lower section can be pulled, and staff select the installation from top still to pacify from below according to scene
Dress, can better meet live use demand.
After being installed, circuit is connected, battery 10 starts to export electric current.Driving motor 23 starts turning.Battery 10 can be with
Using rechargeable battery or dry cell, in the case where the use of field generally use dry cell, to replace at any time, avoid field without
The case where method charges.
When driving motor 23 rotates, left rotary shaft 26 is sequentially driven by drive sprocket 24, chain 212 and driven sprocket 211
Rotation, left rotary shaft 26 drive soft set A27 to rotate together in rotation.Soft set A27 and soft set B210 tightly clamp high-altitude stringing,
Soft set A27 is actively rotated, soft set B210 passive rotation, the two collective effect, and the utility model is pushed to move on the stringing of high-altitude.
Left sliding rack 25 and right sliding rack 28 are hinged with left risers 11 and right risers 15 respectively, can be freely rotated, spring
73 both ends are hung on the left lantern ring 71 of left risers 11 and the right lantern ring 72 of right risers 15, can pull left 25 He of sliding rack
The distance between right sliding rack 28 is close to each other and separate, and then adjust soft set A27 and soft set B210, change soft set to realize
The purpose of frictional force between A27 and soft set B210 and high-altitude stringing.The even meeting slowly of frictional force hour the utility model movement speed
The phenomenon that having skidded, the utility model advances difficult when frictional force is excessive, it is therefore desirable to suitable frictional force.Staff can
To carry the spring of several specifications, to be replaced.
It adjusts repeatedly several times, the utility model is enable to advance at the appropriate speed.Battery 10 is closed at this time, tightens slide plate
Locking nut 34 on 22 makes to slide on the no longer slideway 21 of slide plate 22.Because the length of chain 212 can not change, in adjustment bullet
When spring pulling force, left sliding rack 25 can also be moved, it is therefore desirable to change the position of driving motor 23, to adjust on chain 212
Tension.
After the completion of adjustment, the insulated wire 33 on line roller 32 is pulled out into a section, from this after the conductor loop 9 in left risers 11
The rear of utility model pulls out, at this time insulated wire 33 between left risers 11 and right risers 15, tied up in electric pole or
In pylon.It turns the locking nut 34 in fixing axle 31 and pulls insulated wire 33 back and forth, change between elastic ring 8 and whole line roller 32
Pressure, enable adjust line roller 32 rotate at the appropriate speed, avoid 32 velocity of rotation of line roller too fast.
Finally, starting battery 10, driving motor 23 start turning, the utility model is pushed to move along high-altitude stringing, together
When 32 uniform rotation of line roller, insulated wire 33 is drawn out.Because there is the presence of pulling force, insulated wire 33 substantially can be with high-altitude stringing
It in parallel, is not in the tenesmus of increasing.
After the utility model is moved on the electric pole or pylon on opposite, staff closes battery 10, makes its stopping
It is mobile.Then the locking nut 34 in fixing axle 31 is backed out, elastic ring 8 and line roller 32 are removed, by insulation remaining on line roller 32
Line 33 is thrown on ground.If remaining 33 length of insulated wire is inadequate, needing in addition to connect a section again can connect with ground
Touching, finally removes the utility model from the stringing of high-altitude.So far, whole work is completed.
After high-altitude stringing freezes, ice sheet wraps high-altitude stringing and insulated wire 33 together, at this time live maintenance people
Member pulls with hand insulated wire 33, it is separated with high-altitude stringing, when separated, ice sheet is destroyed the two simultaneously, from high-altitude stringing
On fall.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations,
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that,
It can still modify to technical solution documented by previous embodiment, or be equal to part of technical characteristic
Replacement, and these are modified or replaceed, the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
