Description
Technical field
The utility model relates to the two suspension insulator erection mode forthright shaft towers of a kind of two division and uses jig, and the two suspension insulators of particularly a kind of two divisions set up the cross-arm side jig of shaft tower.
Background technology
At at present 220kV and above transmission line, because transmission capacity is bigger, in order to suppress corona discharge and to reduce line reactance, that improves circuit send electric energy power, and newly-increased 220kV transmission line majority has adopted the two suspension insulator erection modes of double bundle conductor.But brought some stubborn problems also for thus the live line working of circuit: with 220GUZ31 drum type tower is example; Because 220GUZ31 drum type tower is two wiring on the same tower modes of returning; This sections tower is from the general safety structural design, and the cross-arm width is short, and cross-arm side shrouding area is big.If adopt common jig operation, stopped by two insulator string strings under the jig, can't the insulation pull-rod that have gib head be connected with the cross-arm jig; If adopt common side jig, because cross-arm side shrouding area is big, the cross-arm jig can only be installed in and the lead position on same vertical line not, and the insulation arm-tie also can't be connected with jig, so can't realize the charged for replacement insulator operation of this sections tower.
The utility model content
The purpose of the utility model is that the weak point according to prior art provides a kind of two suspension insulators of two divisions that do not receive iron tower cross-arm structure limitations restrict to set up the cross-arm side jig of shaft tower.
The two suspension insulators of a kind of two division set up the cross-arm side jig of shaft tower, comprise two jig body of two symmetric arrays, are connected with jockey between two jig body; Each jig body comprises lead screw device; Jig cross-arm module, aluminium alloy gib head, the connector between aluminium alloy gib head and the screw mandrel; Its structural feature is: described jig cross-arm module is provided with the draw-in groove that snaps in cross-arm; On jig cross-arm module, also be provided with the connecting hole that is used for fixing the jockey between two jig body, on jig cross-arm module, also be provided for installing the through hole of screw mandrel, the degree of depth of described draw-in groove trend, with the connecting hole of jockey, and the length direction that the through hole of screw mandrel is installed parallel; The through hole that being used to of being provided with on the described jig cross-arm module installed screw mandrel is a kind of T shape structure; Screw mandrel is provided with the location steering spindle, and described location steering spindle and screw mandrel are perpendicular, and positioning rotating shaft is stuck in the T shape through hole on the jig cross-arm module.
The two suspension insulators of two divisions of this structure set up the cross-arm side jig of shaft tower; Owing on jig cross-arm module, be provided with this T shape through hole; And the location steering spindle is set on screw mandrel, general side jig can only be installed in directly over the lead with the same vertical line of lead, receives force direction can only receive pulling force vertically downward; After the new jig Design Orientation steering spindle; The side jig can be done the vertical wires axis direction and do certain angle swing, thereby it is stressed to make screw mandrel tilt to the direction of lead, thereby makes jig not receive the restriction of iron tower cross-arm structure.
Described location steering spindle or for to constitute by a bearing pin that passes screw mandrel, or the location steering spindle that can be placed on the screw mandrel by cross constitutes.
Jockey between two jig body is a kind of length-adjustable connecting device.
Described length-adjustable connecting device is served as reasons above that and to be constituted along two pull bars of the jack in a row of its axial distribution or arm-tie, through two pull bars or arm-tie are connected the length that just can realize regulating jockey with respect to different jacks.
Described length-adjustable connecting device is for to be made up of the nut lead screw device.
The nut lead screw device of described adjustable in length includes one section hollow pipe, and the inner chamber at the hollow pipe two ends is provided with screw thread, is provided with two screw mandrels that are complementary with hollow pipe at the two ends of hollow pipe inner chamber, also is provided with the handle that is used to handle on the hollow pipe.
When shaking handle, can realize stretching and contract of the relative hollow pipe of two screw mandrels.
Connector between aluminium alloy gib head and the screw mandrel is articulated on the insulation arm-tie for insulation arm-tie, aluminium alloy gib head.
The aluminium alloy gib head is articulated on the insulation arm-tie; So just can avoid when the double bundle conductor of below and cross-arm jig installation site, top not on same vertical line; The shearing force that the insulation arm-tie will bear double bundle conductor; And if cause continue to tighten up the jig screw mandrel, the suffered shearing force of insulation arm-tie will continue increase, rupture because of shearing force is excessive easily.
Connector between aluminium alloy gib head and the screw mandrel or for the insulation jack line, hang a pulley in the lower end of screw mandrel, the insulation jack line hang on the pulley, then again with the aluminium alloy gib head hang on the insulation jack line on.
Adopt insulation jack line suspension aluminium alloy gib head, and the jack line that will insulate hangs on the pulley that is installed on the screw mandrel, so just can be as required adjustment voluntarily, thereby make jig be in good stress.
The connecting hole that is used for fixing the jockey between two jig body that on jig cross-arm module, is provided with is a screwed hole.
In sum, the advantage of the utility model is:
The two suspension insulators of two divisions of the utility model set up the cross-arm side jig of shaft tower; Can make side jig screw mandrel receive force direction perpendicular to traverse shaft to; The design that has added soft insulation jack line makes stressed connection of safety between jig and the lead; This kind side jig does not receive iron tower cross-arm structure limitations restrict, can carry out jig smoothly and install.Have convenient and flexible installation, have widely applicable advantage.
