Abstract
The utility model relates to a closed fixture for replacing an insulator. The closed fixture at least comprises a clamping piece capable of being placed on an insulator steel cap and two telescopic pull rods hinged with two ends of the clamping piece, and further comprises a bracket and two linking plates respectively hinged with the two telescopic pull rods, wherein a clamping groove is formed at one end of the bracket, the bracket can be clamped on a right-angled hanging board through the clamping groove via a right-angled hanging board back side for fixing an insulator string, and the outer end of the clamping groove can be hinged with a mounting hole on the right-angled hanging board through a bolt; and the other end of one linking plate is hinged with the reverse end of the clamping groove on the bracket, and other end of the other linking plate can be hinged with the right-angled hanging board through another mounting hole on the right-angled hanging board. According to the utility model, the bracket can replace a clamping piece to achieve closed connection by utilizing the two mounting holes on the right-angled hanging board, so as to replace the insulator at the end part.
Description
Technical field
The utility model relates to a kind of jig that the replacing insulator is used on the ultra-high-tension power transmission line that is used for, and specifically a kind of replacing insulator is used the enclosed jig.
Background technology
The employed insulator of 220kV transmission line is main with compound insulator at present, and what use was greatly still still arranged is glass insulator, and it is more general that especially strain tower uses glass insulator.The insulation level and the tensile strength of glass insulator are relatively large, but but self-destruction easily in use.The common method that single strain insulator glass insulator is changed is to use circuit enclosed jig will reveal the adjacent two insulation subcard jails of insulator, tighten up, and makes self-destruction insulator residual fraction lax, and then changes new insulator.The disclosed a kind of so just enclosed jig of Chinese patent CN201946908U, but be to use the method to fix fastener by the two ends insulator steel cap, therefore, can't change the insulator at insulator string two ends.The method of another kind of replaceable termination insulator is to use the machete jig that bunch of insulator is held up and changes, but owing to use heavy machete jig in the air at height, inconvenient operation and increase work are dangerous.
Summary of the invention
The purpose of the utility model provides a kind of replacing insulator and uses the enclosed jig, can be used for changing the insulator at insulator string two ends.
The utility model is achieved in that and comprises a fastener that can be placed on the insulator steel cap at least, and is hinged at two telescopic levers at fastener two ends; Support, support one end has draw-in groove, and support can be stuck on the right angle link plate by the right angle link plate dorsal part of fixed insulation substring through draw-in groove, and the draw-in groove outer end can be hinged through the installing hole on bolt and the right angle link plate; Two gusset pieces that are hinged respectively on two telescopic levers, gusset piece other end be hinged with support draw-in groove backward end, another piece gusset piece other end can be through installing hole on the right angle link plate and right angle link plate hinge.
For making things convenient for adjustable range, each gusset piece has a plurality of installing holes that cooperate with bolt along its length.
Can know by technique scheme; The utility model makes full use of two installing holes on the existing right angle link plate; Be used for fixing gusset piece and support respectively, support supports and is suspended on the right angle link plate through draw-in groove, and support forms through right angle link plate and another gusset piece and is rigidly connected; Thereby substitute fastener, can change the insulator of insulator string end.Substitute support with other fastener and be hinged on two gusset pieces, can be used as common enclosed jig, change other insulators.Not only simple in structure, and use both safety, also very convenient.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that Fig. 1 medium-height trestle A is to structural representation.
Embodiment
As shown in Figure 1, the utility model comprises 6, two telescopic levers of fastener, two gusset pieces 21,22 and support 1.Fastener 6 structures can be referring to Chinese patent CN201946908U.Two telescopic levers are formed by two- way screw mandrel 41,42 and with the sleeve pipe 31,51,32,52 of its two ends thread connection respectively; The other end of sleeve pipe 31,51,32,52 is hinged with fastener 6 two ends and two gusset pieces 21,22 respectively, is fixed with handle 411,421 respectively in the middle of two two- way screw mandrels 41,42; Support 1 one ends have draw-in groove 14; Referring to Fig. 2; The width of draw-in groove 14 is greater than the thickness of the right angle link plate 9,7 of fixed insulation substring 8; Draw-in groove 14 degree of depth are not more than right angle link plate 7 lower end installing holes 71 or 72 distances to angle, arbitrary insulator string 8 hitch points place end, have the installing hole 13 that cooperates with right angle link plate installing hole 71 or 72 on the draw-in groove 14 outer end sidewalls, and support 1 has the installing hole 11 that is hinged with gusset piece 21 at draw-in groove 14 backward ends.
Each gusset piece 21,22 has a plurality of installing holes that cooperate with bolt 211 along its length, can exchange, and support 1 can select diverse location installing hole 211 to connect.
During use, as shown in Figure 1, fastener 6 is sleeved on the insulator steel cap in overhang insulation to be replaced 81 outsides; Gusset piece 22 1 ends are fixed on the right angle link plate 9 through an installing hole on the right angle link plate 9 with bolt 23 again; Support 1 is sleeved on the right angle link plate dorsal part 91 by draw-in groove 14, and passes through the installing hole 13 of its front end and another installing hole on the right angle link plate 9, support 1 is fixed on the right angle link plate 9 with bolt 11; Respectively through rotary handle 411,421; Drive 41,42 rotations of two-way screw mandrel, make fastener 6 and support 1 tighten up, i.e. the insulator 81 of replaceable end to the centre.
