Abstract
The utility model provides a porcelain vase mounting fixture for a high-voltage isolation switch. The porcelain vase mounting fixture comprises two symmetrical semi-annular arms and a pull rod, wherein the two symmetrical semi-annular arms each have one end fastened by one bolt and the other end fixed onto one of the ends of the pull rod, and the pull rod is a telescopic cylindrical pull rod. The porcelain vase mounting fixture has the advantages that: the size and shape of the porcelain vase mounting fixture conforms to the application of general reality; and two porcelain cylinder insulators at the lower portion of an isolation switch structure may be easily fixed when the double-column vertical high-voltage isolation switch is hoisted, so that the possibility is dismissed that the two porcelain vase insulators may bump into each other when the double-column vertical high-voltage isolation switch is hoisted, safety is secured and working efficiency is improved by 80%.
Description
Technical field
The utility model relates to a kind of high voltage isolator porcelain vase fixture.
Background technology
At present, maintenance company of general Utilities Electric Co. need separate the body on isolating switch top when the vertical high voltage isolator of twin columns is disintegrated overhaul with the lifting of bottom insulator.In the composition structure of this type isolating switch, the bottom insulator is made up of two porcelain knob insulators, and wherein, the porcelain knob insulator on right side has been the effect of fixed support disconnecting link, and the porcelain knob insulator in left side is used for controlling disconnecting link opening and closing, and itself can rotate.When the body on disconnecting link top with after insulator lifting in bottom separates, this porcelain knob insulator can tilt to the four sides.If porcelain insulator that rotates does not have fixed support, easily because tilt to cause two porcelain insulator to run foul of each other, thus the security incident of causing.Settling mode in the past:
1. with rope the binding of two porcelain insulators is fixed, when separating with the lifting of disconnecting link body, do not tilted unresolved its intilted problem laterally though solved porcelain vase.
2. fix with wooden stick, make its fixing point not firm, and cause high voltage isolator RTV to come off easily, effort does not save time.
Summary of the invention
At structural deficiency in the prior art, the purpose of this utility model provides a kind of high voltage isolator porcelain vase fixture, be beneficial to be able to when the vertical high voltage isolator of twin columns lifts, fix two the porcelain knob insulators in bottom, thereby may collide mutually between porcelain insulator when having avoided the vertical high voltage isolator of twin columns to lift, improve the fail safe of operation.
For achieving the above object, the technical solution adopted in the utility model provides a kind of high voltage isolator porcelain vase fixture, wherein: described porcelain vase fixture includes symmetrical two semi-circular arms and pull bar, one end of described two semi-circular arms symmetrically passes through bolted respectively, the other end is separately fixed at the two ends of pull bar, and described pull bar is telescopic cylindrical pull bar.
Effect of the present utility model is the application that the shape size of this high voltage isolator porcelain vase fixture meets general reality, can be when the vertical high voltage isolator of twin columns lifts, fix two porcelain knob insulators in bottom that isolating switch is formed like a cork, the problem that may collide mutually between porcelain insulator when thereby the vertical high voltage isolator of solution twin columns lifts, safe and reliable, increase work efficiency 80% simultaneously.
Description of drawings
Fig. 1 is high voltage isolator porcelain vase fixer structure schematic diagram of the present utility model.
Among the figure:
1, semi-circular arm 2, pull bar.
Embodiment
Reaching embodiment by reference to the accompanying drawings is illustrated the structure of high voltage isolator porcelain vase fixture of the present utility model.
As shown in Figure 1, the structure of high voltage isolator porcelain vase fixture of the present utility model is, described porcelain vase fixture includes symmetrical two semi-circular arms 1 and pull bar 2, one end of described two semi-circular arms 2 symmetrically passes through bolted respectively, the other end is separately fixed at the two ends of pull bar 2, and described pull bar 2 is telescopic cylindrical pull bar.Described pull bar 2 comprises two tube-shaped column bodies of internal-external, and external cylinder is long to be 152mm, and internal diameter is 30mm; Inner cylinder is long to be 152mm, and external diameter is 30mm, can, two tube-shaped column bodies are logical freely to stretch, the bolt adjustment fastening.
The diameter of the annular arm that described two symmetrical semi-circular arms 1 form is 185mm, and the diameter of another annular arm of formation is 112mm.Described annular arm outer wrap has one deck to prevent from damaging the rubber sleeve of porcelain vase.
The function of high voltage isolator porcelain vase fixture of the present utility model is achieved in that
The annular arm that described two symmetrical semi-circular arms 1 form is one and is---the annulus that big annular arm is made by diameter 185mm iron ring, to be made by cast iron materials, and the annular arm outer wrap has one deck rubber sleeve, prevents from damaging porcelain vase.Another annular arm that forms is---the annulus that little annular arm is made by diameter 112mm steel ring, to be made by cast iron materials, and the annular arm outer wrap has one deck rubber sleeve, prevents from damaging porcelain vase.
Described intermediate cylindrical pull bar 2 is made by cast iron materials, is divided into outer two cylinders in, forms inner pull bar and outside pull bar.Outside pull bar is cylindrical sleeve, and long is 152mm, and internal diameter is 30mm; Inner pull bar is cylinder, and long is 152mm, and external diameter is 30mm, can freely stretch, and realizes fastening by bolt and outside pull bar.
As shown in Figure 1, when using high voltage isolator porcelain vase fixture of the present utility model, big annular arm is enclosed within on the fixing porcelain insulator, finishes fixing by bolt.By adjusting the length of intermediate draw bar 2, be enclosed within circlet shape arm on the rotating porcelain insulator and be fixed.Like this, vertically two porcelain knob insulators of high voltage isolator bottom just can be finished fixing fast.
