Abstract
本发明公开了一种直线塔带电更换绝缘子卡具，包括有横担侧边卡具，所述的横担侧边卡具包括有定位转向轴、卡具模担横块、绝缘拉板，在定位转向轴内设置有通用丝杆，其结构要点在于：在通用丝杆上设置有沿其轴线方向分布的轴孔，该轴孔为螺纹孔，还包括有连接丝杆，连接丝杆包括有可伸入通用丝杆轴孔的小端及与通用丝杆具有相同的外径及螺纹的大端，在连接丝杆的小端设置有与轴孔相匹配的螺纹。本发明的直线塔带电更换绝缘子卡具，可避免因新旧绝缘子长度不同导致的因长度不够而无法工作，一旦发生新旧不匹配的情况，就可以在不必返工的情况下连接上丝杆。从而使丝杆有足够的裕度来完成新绝缘子的安装。
The invention discloses a jig for live replacement of insulators on a straight line tower, which includes a side jig of a cross arm. A universal screw rod is arranged in the positioning steering shaft, and the main points of its structure are: the universal screw rod is provided with shaft holes distributed along its axis direction, the shaft holes are threaded holes, and also include a connecting screw rod, which includes The small end that can extend into the shaft hole of the general screw rod and the large end that has the same outer diameter and thread as the general screw rod, and the small end of the connecting screw rod is provided with a thread that matches the shaft hole. The straight line tower live replacement insulator jig of the present invention can avoid the inability to work due to insufficient length caused by the different lengths of the old and new insulators. Once the old and new insulators do not match, the screw rod can be connected without rework. So that the screw rod has enough margin to complete the installation of the new insulator.
Description
Technical field
The present invention 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 when changing straight line turriform insulator string, brought 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, when 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 the length that former insulator is adjusted arm-tie again.So not only greatly increased the time that wire stops on insulation pulling plate, also given operating personnel and bring the consumption in muscle power because do over again.。
Summary of the invention
The object of the invention 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, small end in connection wire rod is provided with the screw thread matching with axis hole.
Tangent tower replacing insulator under electrified jig of the present invention, 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, when 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, large end due to connection wire rod has the screw thread identical with general screw mandrel again, therefore 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 integral body with general screw mandrel, thereby play the effect that extends general screw mandrel.
In sum, the present invention's following advantage compared to existing technology:
Tangent tower replacing insulator under electrified jig of the present invention, 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 of the present invention.
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 present invention 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, at the small end of connection wire rod, is provided with the screw thread matching with axis hole.
It is same as the prior art that the present embodiment is not stated part.
