Abstract
The utility model relates to an aerodynamic disk type suspension clamp for replacing glass insulators, which is suitable for live operation of replacing and adding large-rim glass insulator operation in the power transmission profession. The structure of the clamp is that a fixed beam is arranged between lead screws; fasteners are arranged on the fixed beam; and a bowl head clamp is connected with lower portions of the lead screws. The clamp makes replacing large-rim glass insulators to become very easy. The clamp is mounted on an angle iron above a suspension point, and operators work at ground potential and operate far away from a strong electric field. Therefore, safety of live operation is substantially improved, labor intensity of operators is lightened, operation cost is reduced, favorable conditions is brought to live operation, defect elimination of ground potential operation can be performed in time, safe and stable operation of a power grid is guaranteed, reliability of power supply of power transmission lines is effectively improved, and accordingly the clamp is easy to promote in the power transmission production profession.
Description
Technical field
The utility model relates to a kind of insulator replacement tool, relates in particular to a kind of aerodynamic type plate-shaped suspension type glass insulator and changes jig, and the professional charged for replacement that is suitable for transmitting electricity, increase are greatly along glass insulation subjob.
Background technology
At present 220kV line linear string insulation combination is mostly, cross-arm-end be 1 greatly along glass insulator, lower end is synthetic insulator, because circuit is struck by lightning, cause lowly along glass insulator insulation values greatly, there is flashover vestige on surface, is not suitable for reruning and next lightning failure point is searched.In addition in order to improve line insulation level, the former just synthetic insulator of part, also progressively increasing greatly along glass insulator at present, but mostly can only have a power failure and change or increase in prior art.
Summary of the invention
The utility model is for above-mentioned problems of the prior art, provide a kind of aerodynamic type plate-shaped suspension type glass insulator to change jig, solved operating personnel in prior art directly lifting lead wire could shift the problem of load.
The technical solution of the utility model is as follows:
Between leading screw, be provided with built-in beam, built-in beam is provided with securing member, and the bottom of leading screw is connected with a bowl jig.
Described securing member is steady pin or protection clamping plate.

Embodiment
referring to accompanying drawing, in conjunction with specific embodiments, describe the utility model in detail.
embodiment 1
As shown in Figure 1,3, while not drinking water for hanging point angle bar, do not change, increase greatly along glass insulation subjob, leading screw 1 is provided with leading screw spanner, between leading screw 1, be provided with built-in beam 8, built-in beam 8 is provided with steady pin 2, steady pin 2 is fixed on cross-arm angle bar 3 by wing screw, and the bottom of leading screw 1 is connected with the bowl jig 6 matching with insulator bowl head, and a bowl jig 6 employing draw-in grooves and wing screw are fastening.
As shown in Figure 2, change, increase greatly along glass insulation subjob while drinking water for hanging point angle bar, described built-in beam is fixing by protection clamping plate 7, and protection clamping plate 7 are 4 V-type plates.Other structure is with embodiment 1.
The course of work of the present utility model is as follows.
Operating personnel places jig built-in beam directly over cross-arm hanging point, as live line working, need to dress qualified all forcing to submit, steady pin is removed to cross-arm angle bar, tighten wing screw, if when drink water in cross-arm angle bar installation position, utilize protection clamping plate holding clamp built-in beam, adjusting screw spanner, an insulator bowl jig is adjusted to and can be blocked a upper insulator bowl position, by a bowl jig and bowl head card jail, and screw is tightened, check that each portion connects, protection rope for conductor is hung up properly, live line working should select to hang insulating cord, check errorless after, move leading screw, promote whole jig, and drive insulator to promote, when insulator rises to bulb and can deviate from from bowl head, stop promoting, after again checking that each connection is errorless, extract a bowl spring catch, it is pin, extract greatly along glass insulator pin, to along glass insulator, take out greatly, anti-order mounts and dismounts jig.
Protection range of the present utility model is as the criterion with claim, not limited by specific embodiment.
