Abstract
The utility model discloses a clamping tool for the live replacing of an insulator for a tangent tower. The clamping tool comprises a cross-arm side-edge fixture which comprises a positioning steering shaft, a fixture die cross arm block, and an insulating pulling plate. The interior of the positioning steering shaft is provided with a universal screw rod. The structural main points of the clamping tool lie in that the universal screw rod is provided with axle holes distributed along the direction of the axis of the screw rod; the axle holes are threaded holes; the clamping tool also comprises a connecting screw rod; the connecting screw rod comprises a small end which can stretch into the axle holes of the universal screw rod, and also comprises a big end which has the same external diameter and thread as the universal screw rod; the small end of the connecting screw rod is provided with a thread which is matched with the axle holes. The device provided by the utility model can avoid the condition of work failure caused by insufficient length because of the difference between the lengths of new and old insulators, and can be connected with the screw rod with no need of reworking under the condition of unmatched new and old insulators, thereby enabling the screw rod to have the enough margin for completing the installation of the new insulator.
Description
Technical field
The utility model relates to a kind of straight line turriform replacing insulator under electrified instrument, particularly a kind of tangent tower replacing insulator under electrified jig.
Background technology
At current 110kV-220kV and above transmission line, because turriform is various, insulator and gold utensil model are numerous, length differs.Unavoidable appearance and the not identical situation of former insulator length in the time changing straight line turriform insulator string, bring some stubborn problems also to thus the live line working of circuit: if new insulator length is too short, we make up the problem that new and old insulator length difference is brought of rescuing at the screw mandrels of receiving of can also taking measures more: if when insulator oversize, because all wt of wire has all been transferred on insulation pulling plate and jig screw mandrel, in the time that new insulator is greater than than the additional length of former insulator the nargin that screw mandrel returns, at this moment we just have to do over again and again recover former insulator and adjust the length of arm-tie.So not only greatly increase the time that wire stops on insulation pulling plate, also given operating personnel and bring the consumption in muscle power because do over again.。
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of tangent tower replacing insulator under electrified jig that cannot change while avoiding the stylish insulator of replacing insulator to be longer than old insulator is provided.
A kind of straight line tangent tower replacing insulator under electrified jig, include cross arm lateral side clamp, described cross arm lateral side clamp includes location steering spindle, jig mould is carried on a shoulder pole horizontal piece, insulation pulling plate, in the steering spindle of location, be provided with general screw mandrel, its structural feature is: on general screw mandrel, be provided with the axis hole distributing along its axis direction, this axis hole is screwed hole, also include connection wire rod, connection wire rod includes and can stretch into the small end of general screw mandrel axis hole and have the large end of identical external diameter and screw thread with general screw mandrel, be provided with the screw thread matching with axis hole at the small end of connection wire rod.
Tangent tower replacing insulator under electrified jig of the present utility model, in use, can directly or by existing general screw mandrel reequip, on general screw mandrel, along its axis direction, screw thread axis hole is set, in the time crossing long screw and return not as insulator length in operation process, just can connection wire rod be installed until insulator installs at once, utilize the small end of connection wire rod to extend in the axis hole of general screw mandrel, again because the large end of connection wire rod has the screw thread identical with general screw mandrel, therefore when after the axis hole of the general screw mandrel of small end precession of connection wire rod, the large end of connection wire rod just forms an entirety with general screw mandrel, thereby play the effect that extends general screw mandrel.
In sum, the utility model following advantage compared to existing technology:
Tangent tower replacing insulator under electrified jig of the present utility model, can avoid, because of cannot working not because of length that new and old insulator length difference causes, once there is new and old unmatched situation, just can in the situation that needn't doing over again, connecting upper screw rod.Thereby make screw mandrel have enough nargin to complete the installation of new insulator.
Accompanying drawing explanation
Figure 1 shows that the structural representation of versatility connection wire rod described in the utility model.
Figure 2 shows that the schematic diagram after Fig. 1 installs.
Label declaration 1 includes general screw mandrel 5 connection wire rods of location steering spindle 2 jig cross-arm module 3 insulation pulling plate 4.
Embodiment
Below in conjunction with embodiment, the utility model is described in more detail.
Embodiment 1
A kind of straight line tangent tower replacing insulator under electrified jig, include cross arm lateral side clamp, described cross arm lateral side clamp includes location steering spindle 1, jig mould is carried on a shoulder pole horizontal piece 2, insulation pulling plate 3, in location, steering spindle is provided with general screw mandrel 4, on general screw mandrel, be provided with the axis hole distributing along its axis direction, this axis hole is screwed hole, also include connection wire rod 5, connection wire rod includes and can stretch into the small end of general screw mandrel axis hole and have the large end of identical external diameter and screw thread with general screw mandrel, is provided with the screw thread matching with axis hole at the small end of connection wire rod.
It is same as the prior art that the present embodiment is not stated part.
Claims (1)
1. a straight line tangent tower replacing insulator under electrified jig, include cross arm lateral side clamp, described cross arm lateral side clamp includes location steering spindle, jig mould is carried on a shoulder pole horizontal piece, insulation pulling plate, in the steering spindle of location, be provided with general screw mandrel, it is characterized in that: on general screw mandrel, be provided with the axis hole distributing along its axis direction, this axis hole is screwed hole, also include connection wire rod, connection wire rod includes and can stretch into the small end of general screw mandrel axis hole and have the large end of identical external diameter and screw thread with general screw mandrel, be provided with the screw thread matching with axis hole at the small end of connection wire rod.
