Description
Technical field
The utility model is related to electric operating Work tool, and in particular to one kind changes the light-duty auxiliary traction dress of bunch of insulator
Put.
Background technology
Current 500kV transmission circuit insulator strings hang mainly has I shapes, V-arrangement, with the development in epoch, to reduce
Tower head size, reduction track investment cost, diminution line corridor, on 500kV and above electric power line pole tower, especially exist
V-arrangement insulator chain is commonly used on 500kV exchanges compact line, ± 500kV DC lines.When operating insulator chain
Will form insulator arc-over phenomenon after there is bad condition, easily cause line tripping, thus run unit it is carried out must
The replacing wanted.Because the assembling form of V-arrangement string is different compared with I shape strings, and piece number is more, and disk footpath is big, weight weight, insulator center of gravity
With construction hanging point not on the same line, under the influence of insulator chain gravity, " bow " shape is formed, shortens effective length of installation in place
Degree, so that the technical difficulty changed, operating risk increase many compared with I shapes.The Work tool that operation is used mainly has main traction
Rope, cucurbit or suspension rod, grinding machine, 1T (3T) cucurbits or ratchet line lifter etc. are twisted, insulator chain stress are replaced by cucurbit or suspension rod,
Insulator chain is removed or in place.
Being removed, in stage key node in place, V-arrangement is changed using 1T (3T) chain blocks or ratchet line lifter whole
There is problems with insulator string：
1st, 1T (3T) chain blocks weight is in 10-24kg or so in the market, and weight weight is not portable；
2nd, replacement operation be work high above the ground, 1T chain block installation sites be arranged on cross arm of tower insulator hanging point nearby,
Wire yoke plate, operating personnel is limited by job position, not easy to install；
3rd, 1T (3T) chain block needs 3 people to coordinate, and by transmitting rope lifting, increases flow chart, and the activity duration is long, work
Intensity is larger；
4th, steel wire rope easily plays stuck strand, fracture, dislocation in the use of ratchet line lifter, and the phenomenon of abjection is difficult after installation.
Problem above can cause replacing insulator string operation process not smooth so that operating risk coefficient is greatly improved, no
Beneficial to personnel, equipment safety.
Therefore prior art has much room for improvement and develops.
Utility model content
For above-mentioned the problems of the prior art, the purpose of this utility model is that a kind of replacing bunch of insulator of offer is light
Type auxiliary hitch, can replace 1T (3T) chain blocks or ratchet line lifter, to improve operating efficiency and operating personnel
Safety.
To realize object above, the technical solution adopted in the utility model is：
One kind changes the light-duty auxiliary hitch of bunch of insulator, including body, is located in the force-supporting belt of bodies top, sets
The actuating unit on body and the leash positioned at body bottom portion are put, the actuating unit includes self-locking worm and gear
Mechanism, gear drive and volume are to mechanism, the external rocking arm for providing power of worm screw of the self-locking worm-and-wheel gear, institute
Stating gear drive includes being arranged on the intermeshing gear wheel of two couples and little gear of self-locking worm-and-wheel gear both sides,
The worm gear of the self-locking worm-and-wheel gear connects the gear wheel by worm-wheel shaft, and the volume is arranged on described small to mechanism
Rotated between gear and under the drive of the little gear, one end of the leash be connected to the volume in mechanism simultaneously
Make oscilaltion under drive of the volume to mechanism to move.
The other end of the leash is provided with load hook.Load hook is used to hook the objects such as the insulator chain of needs lifting.
Tight locking button is additionally provided with the force-supporting belt.It is easy to for this draw-gear to be fixed on the working positions such as cross-arm, wire yoke plate
Put.
The replacing light-duty auxiliary hitch of bunch of insulator of the present utility model, using self-locking worm gear structure, should
Mechanism possesses auto-lock function, may be implemented in the locked stop of optional position in hoisting process, so as to avoid using other transmission sides
Formula needs to set complicated lockable mechanism, therefore overall structure is simple, with small volume, lightweight, portable advantage,
Change in the operation process of insulator chain, the present apparatus need not be lifted by crane separately, only need inserter bag such that it is able to reduce
Labour intensity, improves operating efficiency.

Specific embodiment
Content of the present utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment：
Refer to shown in Fig. 1 and Fig. 2, one kind changes the light-duty auxiliary hitch of bunch of insulator, including body 1, wears
Force-supporting belt 2 at the top of body 1, the actuating unit being arranged on body 1 and the leash 3 positioned at the bottom of body 1, it is described
Actuating unit includes self-locking worm-and-wheel gear 4, gear drive 5 and rolls up to mechanism 6, the self-locking worm and gear machine
The external rocking arm 7 for providing power of worm screw of structure 4, the gear drive 5 includes being arranged on 4 liang of self-locking worm-and-wheel gear
The intermeshing gear wheel of two couple of side and little gear, the worm gear of the self-locking worm-and-wheel gear 4 are connected by worm-wheel shaft
The gear wheel, the volume is arranged between the little gear to mechanism 6 and is rotated under the drive of the little gear, institute
The one end for stating leash 3 is connected to the volume in mechanism 6 and making oscilaltion under drive of the volume to mechanism 6 and move.
Wherein, the other end of the leash 3 is provided with load hook 8.Load hook 8 is used to hook the insulator chain for needing lifting
Deng object.
