Second supporting bracket 14 of described insulated platform also is to arrange in pairs, and the mid point of described second supporting bracket 14 is articulated on the described central support shaft 17, and described second supporting bracket 14 is along the axially-aligned of described central support shaft 17;
Described second supporting bracket 14 is divided into restrained end and free end, and described insulated platform closes up, described second supporting bracket, 14 maintenance levels; Described insulated platform launches, the mutual clamping of first end of the restrained end of described second supporting bracket 14 and described first supporting bracket 13, and the free end of described second supporting bracket 14 contacts with the bottom surface of the middle part engraved structure of described basic platform 11.
The bottom surface of She Ji the purpose free end that is the clamping of first end by first supporting bracket 13 and second supporting bracket, 14 restrained ends and second supporting bracket 14 and the middle part engraved structure of basic platform 11 contacts like this, can be with the described weight transfer of the people on the insulation footboard 12 that is applied to basic platform 11, guarantee a kind of expansion live line working of the present invention stablizing with the insulated platform center of gravity, in use do not turn on one's side, thereby guaranteed operating personnel's personal safety.
When guaranteeing that described insulated platform launches, clamping correctly between first end of the restrained end of described second supporting bracket 14 and described first supporting bracket 13, described insulated platform closes up, when described second supporting bracket 14 kept levels, two second supporting brackets 14 in second supporting bracket 14 that arranges also should be respectively and are kept in touch between first end of first supporting bracket 13 of described basic platform 11 both sides in pairs.
In Fig. 1, described insulated platform closes up, be positioned at the restrained end and first end in contact that is positioned at first supporting bracket 13 on described basic platform 11 right sides of second supporting bracket 14 of front side, be positioned at the restrained end and first end in contact that is positioned at first supporting bracket 13 in described basic platform 11 left sides of second supporting bracket 14 of rear side.
In Fig. 2, described insulated platform launches, be positioned at the restrained end and the first end clamping that is positioned at first supporting bracket 13 on described basic platform 11 right sides of second supporting bracket 14 of front side, be positioned at the restrained end and the first end clamping that is positioned at first supporting bracket 13 in described basic platform 11 left sides of second supporting bracket 14 of rear side.
In order further to guarantee live line working personnel's personal safety, on the end face of a kind of expansion live line working of the present invention with the insulation footboard 12 of insulated platform some central supported hole 110 is set, see also Fig. 3, be positioned on the end face of insulation footboard 12 of horizontal cross both sides of basic platform 11 and be provided with eight central supported holes 110 altogether, in order to guardrail to be installed, the montant 111 of described guardrail is plugged in the central supported hole 110 on the end face on the described insulation footboard 12, the railing 112 of described guardrail is connected with described montant 111 with corner three-way pipe 114 by T tube 113, after the described fence installation, operating personnel's personal safety has had further assurance.
Below by accompanying drawing 4 described a kind of expansion live line working insulated platform of the present invention is described, Fig. 4 is example with insulation footboard 12, first supporting bracket 13 and second supporting bracket 14 that is positioned at described basic platform 11 left sides only, comes principle is described.
The live line working personnel stand on the insulation footboard 12, and self gravity G is applied on the described insulation footboard 12, insulation footboard 12 passes to described gravity G at second end of first supporting bracket 13 then, balance for the moment that keeps first supporting bracket 13 centered by back shaft 16, first end of described first supporting bracket 13 is subjected to a downforce F1, this downforce F1 is from the restrained end of second supporting bracket 14, and the restrained end of second supporting bracket 14 also is subjected to the reaction force into downforce F1, and this reaction force is elastic force N1; Balance for the moment that keeps second supporting bracket 14 centered by central support shaft 17, the free end of described second supporting bracket 14 also is subjected to the elastic force N2 that another one makes progress, because the free end of described second supporting bracket 14 contacts with the bottom surface of the middle part engraved structure of described basic platform 11, so the application of force person of described elastic force N2 is basic platform 11, correspondingly, the bottom surface of described basic platform 11 also is subjected to the reaction force of elastic force N2, and this reaction force is downforce F.In sum, transmission by first supporting bracket 13 and second supporting bracket, 14 lever constructions, live line working personnel's gravity G has transmitted on the basic platform 11, become the downforce F for basic platform 11, described like this insulated platform center of gravity can keep stable, thereby guarantees live line working personnel's personal safety.
Simultaneously, can pass from alternate safely in order to guarantee described insulated platform, its size also is worthy of careful study.Such as at present 10kV supply line two alternate distances are 60cm, thus described insulated platform close up, the end face size 60 * 40cm of described insulated platform, described insulated platform launches, the end face of described insulated platform is of a size of 60 * 180cm.When the supply line to other specification carried out hot line job, the size of described insulated platform should be made corresponding adjustment.
Simultaneously in order to make a kind of expansion live line working of the present invention with insulated platform alternate passing more safely, the while lighter weight, adopt insulating material such as rectangle fiberglass pipe, Fiber glass rod and glass fiber laminate as stock, by inlay, technology such as hole axle connection is assembled.See also Fig. 5, basic platform described in Fig. 5 11 is made up of two glass fiber laminates that be arranged in parallel and four fiberglass pipes between described glass fiber laminate or Fiber glass rod, to form the middle part engraved structure of described basic platform 11.The material of described insulation footboard 12 is glass fiber laminate, the described rotating shaft 15 in described insulation footboard 12 upper edges axially be provided with six guide-track grooves 18 vertical with rotating shaft 15, the material of described guide-track groove 18 is nylon; Corresponding described insulated platform axially is provided with six pairs of first supporting brackets 13 and second supporting bracket 14 along central support shaft 17, and second end of described first supporting bracket 13 flexibly connects by shifting axle 19 and described insulation footboard 12.Wherein the material of first supporting bracket 13 and second supporting bracket 14 is fiberglass pipe or Fiber glass rod, and a kind of expansion live line working of the present invention is to strengthen the structural strength that insulated platform is used in the expansion live line working with insulated platform along the many purposes to first supporting bracket 13 and second supporting bracket 14 of axially arranging of described central support shaft 17.Certainly, the quantity of guide-track groove 18, first supporting bracket 13 and second supporting bracket 14 is can be according to adjusting for the requirement of described insulated platform intensity.
Through detecting, adopt a kind of expansion live line working of glass fibre material can tolerate 1min power frequency 50kV with insulated platform, lightning impulse 80kV, but a kind of expansion live line working of the present invention adopts other materials also can reach constructed index with insulated platform.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
