Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of reasonable in design, simple in structure, novel insulation drainage thread fixed support that can solve potential safety hazard is provided.
The present invention solves its technical problem and realizes through following technical scheme:
A kind of novel insulation drainage thread fixed support; It is characterized in that: comprise insulation dop, insulating support main body and base; Insulation dop hinge is contained in the upper end of insulating support main body, forms a cable-through hole that is used to install the insulation drainage thread between this insulation dop and the insulating support main body upper surface, and base is installed in the lower end of insulating support main body; Make a draw-in groove that is used to clamp iron cross arm on this base, the bottom surface of base is installed the screw that holds out against that is used to hold out against iron cross arm.
And the sidewall of said insulating support main body upper end is installed a snap close, and the lower end hinge of this snap close is contained on the insulating support main body, and withhold on the insulation dop upper end of this snap close when the insulation dop is closed.
And the cable-through hole that is used to install the insulation drainage thread is made up of two deep-slotted chip breaker make-ups, and these two deep-slotted chip breakers are prepared in the bottom surface of insulation dop and the upper surface of insulating support main body.
And a draw ring is installed in the upper end of said insulation dop.
And the axial length of said insulating support main body is 0.5 meter.
And the outer surface of described insulating support main body is made a plurality of annular protrusions vertically.
And described insulation dop and insulating support main body all use epoxy resin to process.
And described base is a cast iron base, and the made draw-in groove of this base is for being horizontally disposed with or being obliquely installed.
Advantage of the present invention and beneficial effect are:
1, this fixed support mainly is made up of insulation dop, insulating support main body and base; Base is used for this fixed support is fixed on the overhead transmission line iron cross arm; The insulating support main body is used to guarantee that drainage thread and earth electrode have enough safe distances; The head dop is used for fixing the insulation drainage thread, prevents the drainage thread swing.Therefore use this support can guarantee to insulate safe distance of earth electrodes such as drainage thread and iron cross arm, solve in the operation process drainage thread and swing a safe difficult problem that is caused.
2, the draw-in groove of base according to the limit with in mutually respectively the design; The draw-in groove of middle phase support is for being horizontally disposed with; The draw-in groove of limit phase support is the setting of outward inclining formula; Have enough safe distances to guarantee to insulate after drainage thread is installed, so this fixed support is flexible and convenient to use, can be installed on the iron cross arm of diverse location.
3, insulation dop in this fixed support and insulating support main body all use homemade insulating material epoxy resin to process, and its dielectric strength is 4.5 times a rated voltage, meet the rules requirement of preventive trial fully, have reached the professional requirement of live line working.
4, the outer surface of insulating support main body is made a plurality of annular protrusions vertically, and this annular protrusion both can improve insulation property, is convenient to operating personnel again and grips.
5, the present invention be a kind of design ingenious, simple to operate, low cost of manufacture, security reliability high, be adapted at using the insulation drainage thread to carry out the novel insulation drainage thread fixed support of applying in the on-load operation; This device can be fixed the drainage thread that temporarily insulate reliably, the safe distance of the earth electrodes such as drainage thread and cross-arm of guaranteeing to insulate, solves the safe difficult problem that the drainage thread swing causes in the operation process, the fail safe that improves live line working.

Embodiment
Through specific embodiment the present invention is made further detailed description below, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of novel insulation drainage thread fixed support comprises insulation dop 1, insulating support main body 6 and base 8.The insulating support main body adopts epoxy resin to process, and the outer surface of insulating support main body is made a plurality of annular protrusions 5 vertically.The length of insulating support main body need guarantee that drainage thread and iron cross arm have enough safe distances, and the axial length of insulating support main body is 0.5 meter in the present embodiment.
The insulation dop adopts epoxy resin to make; This insulation dop hinge is contained in the upper end of insulating support main body; Make two deep-slotted chip breakers respectively at the bottom surface of insulation dop and the upper surface of insulating support main body; Behind insulation dop and insulating support main body fastening, these two deep-slotted chip breakers form a cable-through hole 3 that is used to install the insulation drainage thread.
A draw ring 2 is installed in the upper end of insulation dop.Sidewall in insulating support main body upper end is installed a snap close 4, and the lower end hinge of this snap close is contained on the insulating support main body, and withhold on the insulation dop upper end of this snap close when the insulation dop is closed.
Base is a cast iron base; Base is installed in the lower end of insulating support main body; Make a draw-in groove 9 that is used to clamp the overhead transmission line iron cross arm on this base; The made draw-in groove of this base is for being horizontally disposed with or being obliquely installed, and can both make interim drainage thread of insulation and the enough safe distances of iron cross arm maintenance when guaranteeing to use the online roadside of insulating support mutually with middle operation mutually.Its concrete form is not limit, and in the present embodiment, base is installed in the bottom of insulating support main body through connecting plate 7, and as shown in Figure 1, draw-in groove is for being horizontally disposed with, and is as shown in Figure 2, and when connecting plate was angular structure, draw-in groove was obliquely installed.The bottom surface of base is installed one and is held out against screw 10, and this upper end that holds out against screw extends to draw-in groove inside, so that hold out against iron cross arm.
