Description
Technical field
The invention belongs to power accessories technical field, and in particular to a kind of folding lightweight goes out single string strain insulator insulation
Substring device.
Background technology
Insulator is a kind of special insulation control, can be played an important role in overhead transmission line.Between one's early years absolutely
Edge is used for electric pole, and the one end for being slowly developed in high type high-tension bus-bar connection tower has hung the insulator of many plate-likes, and it is
In order to increase creep age distance, generally it is made up of glass or ceramics, is just insulator.Insulator should not be negative due to environment and electricity
Lotus condition change caused by various electromechanical stress and fail, otherwise insulator would not produce great effect, will damage
The use of evil whole piece circuit and service life.When going out single string strain insulator string, operating personnel only rides on the insulator,
Due to adding out-of-balance force, insulator chain can be tilted and rotated, therefore operating personnel often falls down insulator chain, increases
Work risk is added.And this operating type difficulty is larger, therefore many people are caused to go out single string strain insulator string.Though
So someone carries out out single string strain insulator string using the method for climbing rope ladder at present, but not only labor intensity is big for such a method,
And need to carry a large amount of heavier Work tools, the place that some vehicles can not be reached, staff only has manpower transport, works
Difficulty and intensity are all larger, and time-consuming longer.Therefore, development one kind is needed badly to be convenient for carrying, and operation simply goes out single string
Strain insulator string devices.
The content of the invention
Go out single string strain insulator string devices it is an object of the invention to provide a kind of folding lightweight simple in construction.
The object of the present invention is achieved like this, including transverse supporting rod and vertical support bar, and described transverse supporting rod is by can
Fold mechanism, which is fixed on vertical support bar, constitutes creeping ladder, and described vertical support bar is made up of multiple vertical support bar units, and every two
Tie point between individual vertical support bar unit is the tie point of transverse supporting rod and vertical support bar, and described creeping ladder one end is set
Hanged hook, the other end sets stay hook.
The present invention uses the space-consuming that the device is substantially reduced after folding structure, folding, can be loaded with a bag,
Staff is facilitated to carry；Using new lighter material, alleviator weight, staff can directly carry tower and enter enforcement
With；Front and back position of the present invention designs hanged hook and fixed hook structure according to wire and steel tower, and hanged hook is directly hung on wire,
Stay hook is buckled on steel tower, and staff is quick and easy for installation, and reliable and stable, safe.Using double-layer sleeve structure
Transverse supporting rod is reinforced, job safety is ensured.Because insulator rotates the work caused when the present invention solves out single insulator string
The problem of personnel fall, convenient use solves the problem of majority can not go out single insulator string, is set while also solving other
It is standby heavier, it is difficult to carry the problem of installing.
