Because loop resistance wire clamp requires wire clamp jaws, tightness is very high, therefore adopts clamping screw that jaws copper part is carried out effectively fixing and further clamped.Jaws partly adopts copper part, and preferably pure copper material, enough little to guarantee itself and isolating switch and isolation switch wire clamp contact resistance, and do not affect test figure.
Also include the second fixing iron member, the first pulley and the second pulley, the first pulley is arranged on the spring member of chuck, the second fixing iron member is arranged on insulating bar, be positioned at the first fixed clip and chuck centre position, the second pulley is arranged on the bottom of the second fixing iron member, one end of stay cord is fixed on the tail end of rear folder, and sequentially walks around tail end, second pulley of the first pulley, front folder, is finally fixed on pull bar bottom.
The first pulley is for the bracing wire of fixing and transmission folding chuck, the second pulley is for supporting and the stay cord of transmission from chuck to pull bar, the second fixing iron member is for installing the second pulley, the pulley gearing that the first described pulley and the second pulley form can fixed pulling rope track, thereby make stay cord in two pulley room transmissions, complete the folding operation to chuck.
Insulating bar is a kind of hollow stem, and its tail end has embedded connecting piece.
Like this, can continue as required to connect insulating bar, lengthen insulating bar, to meet the length requirement of operation.
The first fixing iron member includes circular external member and extends fixture, and circular external member cover is trapped among on insulating bar, extends the side that fixture is positioned at insulating bar, hinged with pull bar.
The second described fixing iron member and the first fixing iron member structural similarity, wherein the second pulley extends between fixture at two of the second fixing iron member.The first fixing iron member is for cylinder lever connecting rod and insulating bar, controls pull bar and just can easily pull stay cord, thereby freely control the folding of insulating bar top chuck.
In sum, the utility model provides a kind of high-potting altitude test fixture, adopts remote control chuck, high-potting wiring is carried out to high-altitude line sending, wiring and thread-changing.The series of problems of having avoided high altitude vehicle or manpower climbing line sending to bring, the utility model is simple in structure, easy to operate, and the smooth inlet wire that operating efficiency is high, guaranteed various altitude test wiring, has guaranteed operating personnel's personal safety.
Accompanying drawing explanation
Figure 1 shows that the structural representation of altitude test furniture for the high-potting described in most preferred embodiment.
Figure 2 shows that the structural representation of chuck in Fig. 1.
Figure 3 shows that the structural representation of the first fixing iron member and the second fixing iron member in Fig. 1.
Below in conjunction with embodiment, the utility model is described further.
Embodiment
Most preferred embodiment:
With reference to accompanying drawing 1, high-potting altitude test fixture, includes chuck 1, insulating bar 2, the first fixing iron member 3, the second fixing iron member 4, the first pulley 5, the second pulley 6, stay cord 7 and pull bar 8.
The structure of chuck 1 on the basis of accompanying drawing 1 with reference to accompanying drawing 2, two clamping screws 14 that chuck 1 includes front folder 11, rear folder 12, the spring member between two folders 13 and is positioned at jaws.Front folder 11 is hinged by spring member 13 and rear folder 12 pretensions, and two clamping screws 14 distribute in opposite directions and withstand on the Zijin copper part 15 of jaws.
The first fixing iron member 3 is identical with the structure of the second fixing iron member 4, with reference to accompanying drawing 1 and accompanying drawing 3, include circular external member 31 and extend fixture 32, circular external member 31 covers are trapped among on insulating bar, extension fixture 32 is positioned at a side of insulating bar, clamping with bolts.
With reference to accompanying drawing 1, chuck 1 is fixedly connected with insulating bar 2 by plastic fastening 9; The first fixing iron member 3 is arranged on the rearward end of insulating bar 2, and the lower end of this first fixing iron member 3 (extension fixture) is hinged with the upper end of pull bar 8.The first pulley 5 is arranged on the spring member of chuck 1, the second fixing iron member 4 is arranged on insulating bar 2, be positioned at the first fixed clip 3 and chuck 1 centre position, the second pulley 6 is arranged on the bottom (extension fixture) of the second fixing iron member, one end of stay cord 7 is fixed on the tail end of chuck 1 rear folder, and sequentially walk around tail end, second pulley 6 of the first pulley 5, front folder, be finally fixed on pull bar 8 bottoms.
Consider the requirement for height of work high above the ground, may need insulating bar long enough, now insulating bar can be made to the structure that can continue, at the tail end of insulating bar, have embedded T-shaped web member 21, with continued access insulating bar, in figure, 22,22 is the operation insulating bar of continued access.In addition, insulating bar 2 is a kind of hollow stem, by the insulating material of epoxy resin, is made, and the electric current line of wire clamp and voltage can pass hollow insulating bar.
