Abstract
The utility model provides a clamping tool used for changing a single-strand insulator. The clamping tool used for changing the single-strand insulator can clamp a socket-clevis eye of the single-strand insulator on a side of a lead. The clamping tool used for changing the single-strand insulator is composed of two long-strip-shaped plates. The centers of the plates are provided with three corresponding bolt holes respectively. Through penetrating three fixing bolts through the three bolt holes and fixing the bolts with nuts, the socket-clevis eye is clamped by the two plates. By adopting the utility model, the clamping tool used for changing the single-strand insulator can be in a suitable connection position for performing hotline change conveniently and smoothly when replacing the single-strand insulator with a double-strand insulator, so that the efficiency of change operation can be improved.
Description
Technical field
The utility model relates to a kind of jig, relates in particular to a kind of jig of single insulator string being changed usefulness in transformer station.
Background technology
In recent years, along with the newly-built of transmission line or transform, the insulator for the 220kV circuit of transformer station has generally adopted two insulator string syndetons, to improve insulation property.But transformer station's inner insulator also exists the list polyphone of some to connect pattern at present.Because along with high development of social economy, power consumption also increases greatly, to the also raising year by year of requirement of power supply reliability, therefore, the live line working of for example insulator being changed in the transformer station is had higher requirement.Single insulator string in the charged for replacement transformer station, be satisfy safe distance under the situation, must use special connecting piece and reliably insulator string is tightened up to change the work of single insulator string.But because the particularity of the connector that the single insulator string of replacing is used because lead one side can't provide safe and reliable link position, therefore, has been brought bigger difficulty to live line working, the operating personnel is difficult to successfully change single insulator string in charged occasion.
The utility model content
In view of the above problems, the purpose of this utility model is, a kind of jig that single insulator string is used of changing is provided, its structure is very simple, by the jig that uses single insulator string to use, thereby can when single insulator string being replaced by two insulator string, suitable link position be arranged this jig, convenient and successfully carry out charged for replacement, can improve the replacing efficiency of operation.
For achieving the above object, the jig that the single insulator string of replacing of the present utility model is used, the socket-clevis eye of described single insulator string of lead side is blocked, the characteristics of this jig are, described jig is made of the sheet material of two strips, central authorities at each described sheet material are respectively equipped with three corresponding bolts hole, fix with nut and clamp described socket-clevis eye by described two sheet materials by three set bolts being passed three bolts hole.
In said structure, described three bolts hole equidistantly separate, clamped under the state of described socket-clevis eye by described two sheet materials utilizing described three set bolts and described nut, a described bolt that mediates passes in the middle of described socket-clevis eye, and other two described bolts pass from the both sides of described socket-clevis eye respectively.
The jig that adopts the single insulator string of replacing of the present utility model to use, its structure is very simple, and is easy for installation, uses flexibly, highly versatile, and, can effectively provide two link positions for single insulator string, be convenient to install the multiple load tightening device of cooperation, tighten up and change insulator, safety and efficient.
Description of drawings
Fig. 1 is the front view of jig under the use state that the single insulator string of expression replacing of the present utility model is used.
Among the figure, 1 is socket-clevis eye, and 2 is set bolt, and 3 is jig, and 4 is insulator.
Embodiment
Below, describe concrete structure of the present utility model and beneficial effect in detail according to Figure of description.
As shown in Figure 1, the jig 3 that the single insulator string of replacing of the present utility model is used, the socket-clevis eye 1 of single insulator string 4 of lead side is blocked, this jig 3 is made of the sheet material of two strips, central authorities at each sheet material are respectively equipped with three corresponding bolts hole (not shown), and are fixing and clamp socket-clevis eye 1 by two sheet materials with nut (not shown) by three set bolts 2 being passed three not shown bolts hole.
In said structure, three bolts hole equidistantly separate, clamped under the state of socket-clevis eye 1 by two sheet materials utilizing three set bolts 2 and not shown nut, a set bolt 2 that mediates passes in the middle of socket-clevis eye 1, and other two set bolts 2 pass from the both sides of socket-clevis eye 1 respectively.
The jig 3 that the single insulator string of replacing of the present utility model of employing said structure is used, on shown in Figure 1, following two parts and socket-clevis eye 1 is blocked from both sides in the lead side, then with three screws pass respectively on the jig 3 three bolts hole and from the both sides of socket-clevis eye 1 and the centre is passed and fix with nut, and the jockey (not shown) of jig 3 both sides can connect various bearings (not shown), as screw mandrel, walk two and walk three tackle pulley, the hydraulic pressure tightener, instruments such as machinery tightener, single insulator string is tightened up, make insulator just single insulator string can be replaced by two insulator strings in lax back simultaneously then.
Therefore, jig of the present utility model, its structure is very simple, can suitable link position be arranged this jig when single insulator string being replaced by two insulator string, and is convenient and successfully carry out charged for replacement, can improve the replacing efficiency of operation.
Claims (2)
1. change the jig that single insulator string is used for one kind, the socket-clevis eye of described single insulator string of lead side is blocked, this jig is characterised in that, described jig is made of the sheet material of two strips, central authorities at each described sheet material are respectively equipped with three corresponding bolts hole, fix with nut and clamp described socket-clevis eye by described two sheet materials by three set bolts being passed three bolts hole.
