Description
Technical field
The invention belongs to power accessories technical field, be specifically related to a kind of folding lightweight and go out single string strain insulator string devices.
Background technology
Insulator is a kind of special insulation control, can play an important role in overhead transmission line.In one's early years, insulator is used for electric pole, and slowly develop and hung the insulator of a lot of plate-like in one end of high type high-tension bus-bar connection tower, it is made up of glass or pottery usually in order to increase creepage distance, is just insulator.Insulator should not to change the various dynamo-electric stress that causes and losing efficacy due to environment and electric loading condition, otherwise insulator would not produce great effect, will damage use and the service life of whole piece circuit.When going out single string strain insulator string, operating personnel only rides on the insulator, and owing to adding out-of-balance force, insulator string can tilt and rotate, and therefore operating personnel often can fall down insulator string, considerably increases work risk.And this operating type difficulty is comparatively large, therefore cause a lot of people not go out singly to go here and there strain insulator string.Although someone adopts the method for climbing rope ladder to carry out singly to go here and there strain insulator string at present, but not only labour intensity is large for this kind of method, and need to carry Work tool heavier in a large number, the place that some vehicle can not arrive, staff only has manpower transport, work difficulty and intensity are all comparatively large, and consuming time longer.Therefore, need development one badly and be convenient for carrying, and operation simply goes out single string strain insulator string devices.
Summary of the invention
The simple folding lightweight of a kind of structure is the object of the present invention is to provide to go out single string strain insulator string devices.
The object of the present invention is achieved like this, comprise transverse supporting rod and vertical support bar, described transverse supporting rod is fixed on vertical support bar by foldable mechanism and forms creeping ladder, described vertical support bar is made up of multiple vertical support bar unit, tie point between every two vertical support bar unit is the tie point of transverse supporting rod and vertical support bar, described creeping ladder one end arranges hanged hook, and the other end arranges stay hook.
The present invention adopts folding structure, greatly reduces taking up room of this device, can load, facilitate staff to carry with a bag after folding; Adopt novel comparatively light material, alleviator weight, staff can directly carry tower and use; Front and back position of the present invention designs hanged hook and stay hook structure according to wire and steel tower, and hanged hook directly hangs on wire, and stay hook is buckled on steel tower, and staff is quick and easy for installation, and reliable and stable, and fail safe is high.Adopt double-layer sleeve structure to reinforce transverse supporting rod, ensure job safety.Because insulator rotates the problem that the staff that causes falls when the invention solves out single insulator string, easy to use, solve the problem that majority can not go out single insulator string, also solve other equipment heavier simultaneously, be difficult to the problem of carrying installation.
