Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1, lead wire and earth wire aluminium hydraulic pressed connecting pipe high-altitude alignment tool, comprise bending resistance crossbeam 1, run through the leading screw 2 be connected in the middle part of bending resistance crossbeam 1 and with bending resistance crossbeam 1 threaded engagement, the top of described leading screw 2 is provided with handle 3, leading screw 2 bottom is provided with the alignment head location-plate 4 for extruding aluminium hydraulic pressed connecting pipe 8, also comprise two stationary fixtures 5 being arranged symmetrically in described leading screw 2 both sides, the top of described stationary fixture 5 is connected with the end winding support of bending resistance crossbeam 1, stationary fixture 5 bottom be provided with match with the shape angles of aluminium hydraulic pressed connecting pipe 8, opening is towards the rebate 6 of described bending resistance crossbeam 1.
The course of work of the present utility model and principle as follows:
Between the rebate 6 needing the aluminium hydraulic pressed connecting pipe 8 of alignment to be placed on stationary fixture 5 bottom and leading screw 2, and the part arched upward is facing to leading screw 2, then turning handle 3, leading screw 2 is rotated relative to bending resistance crossbeam 1, the part that downward pressing aluminium hydraulic pressed connecting pipe 8 arches upward, unclamp aluminium hydraulic pressed connecting pipe 8 after keeping a period of time, complete alignment work.
Further, the cross section of described rebate 6 is V-shaped; Described bending resistance crossbeam 1 is provided with at least two to keeping the tapped through hole 7 at interval, and every double thread through hole 7 is symmetrically distributed in leading screw 2 both sides, and the top of two stationary fixtures 5 is bolted to wherein on a pair tapped through hole 7 by single head punching; The end of described leading screw 2 bottom is through on alignment head location-plate 4, and when leading screw 2 rotates, alignment head location-plate 4 and leading screw 2 produce relative sliding.
The angle that the rebate 6 of V-type crimps rear correspondence according to aluminium hydraulic pressed connecting pipe 8 is shaped (being generally 60 degree), increase the contact area of fixture and aluminium hydraulic pressed connecting pipe 8 on the one hand, avoid pressure in alignment process and cross macrolesion aluminium hydraulic pressed connecting pipe 8, it also avoid workpiece shift in alignment process on the other hand, significantly reduce the working strength of operator, a people can easily complete, and has increased substantially the operating efficiency of work high above the ground.In actual applications, designed clamp jaw width for the requirement of current maximum diameter of wire (65mm), can not considered too many remaining, alleviates instrument weight; In alignment length, can consider to regulate between 150mm and 250mm two grades, the bending resistance crossbeam 1 of design corresponding length and two double thread through holes 7, can adopt between stationary fixture 5 and bending resistance crossbeam 1
the single head punching bolt of high strength connects, ease of assembly, and longitudinally-moving remaining is large, and aluminium hydraulic pressed connecting pipe 8 alignment meeting various bending length uses; Leading screw 2 can adopt
high strength flat thread leading screw, easy manipulation can make alignment head location-plate 4 reach the pressure of more than 500kg.Alignment head location-plate 4 can slide relative to leading screw 2, namely when leading screw 2 rotates, alignment head location-plate 4 can be driven to move up and down, but when alignment head location-plate 4 is pressed on the aluminium hydraulic pressed connecting pipe 8 of alignment, alignment head location-plate 4 just no longer rotates with leading screw 2, thus decreases the friction between alignment head location-plate 4 and aluminium hydraulic pressed connecting pipe 8, in prior art, have the mode much realizing this connection, this is not restricted.
After processing, this alignment tool overall weight is no more than 2kg, light and beautiful, and easily assemble, be easy to carry, mechanical strength is high; Utilize this instrument can obtain significant techno-economic effect.
The scope of application of aluminium hydraulic pressed connecting pipe alignment tool of the present utility model can contain current electric power system outdoor use more than 95% of aluminium hydraulic pressed connecting pipe model, meet the alignment use that diameter is the various cross section wire of 20mm to 65mm (LGJ-800/100 uses), the aluminium hydraulic pressed connecting pipe of ground wire, meet light, high strength, easily assembling, easy to operate, portable work high above the ground Environment Design principle.
Above-listed detailed description is illustrating for the utility model possible embodiments, and this embodiment is also not used to limit the scope of the claims of the present utility model, does not allly depart from the equivalence that the utility model does and implements or change, and all should be contained in the scope of the claims of this case.
