By above-mentioned known, because the length of coupling assembly has determined the width of straight line double-hung card, so cannot well be suitable for for the cross-arm of different in width.If meet different in width cross-arm by the coupling assembly of changing different length, can cause the cost of fund of equipment to increase.In addition, draw-in groove place easily twists, and easily causes damage, and then brings potential safety hazard to work high above the ground.
Summary of the invention
In view of this, the utility model proposes a kind of split type jig of changing cross-arm-end linear string insulator, by between two jigs no longer by the connection of coupling assembly, thereby can be suitable for the cross-arm of different in width.In addition, can also be by firm jig being connected on cross-arm, to improve the fail safe of operation.
The technical solution of the utility model is: a kind of split type jig of changing cross-arm-end linear string insulator, comprise the clamp of one group of symmetry, the clip parts that are connected to the retraction assemblies on clamp and are connected with retraction assemblies by insulated tension pole, described clamp comprises vertical fixing horizontal clamp and parcel clamp mutually, parcel clamp is relatively spliced and forms by two half symmetrical plates, half plate of two splicings is provided with the die cavity that can hold cross-arm angle bar, screw fastening is passed through in the lower end of two and half plates, screw fastening is passed through in one end of upper end and horizontal clamp, described retraction assemblies is connected to the other end of horizontal clamp, the below of horizontal clamp is provided with deck, the bottom of deck is provided with the groove with cross-arm angle bar thickness adaptation, groove can level be overlapped on the upper surface of cross-arm angle bar.
Further, described clip parts are two thread-lifting hooks, are connected to the lower end of two insulated tension poles.
Further, described clip parts are closed fixture, and the two ends of closed fixture are connected to the lower end of two insulated tension poles.
The beneficial effects of the utility model: because each retraction assemblies all can, by horizontal clamp and parcel firm one end that is connected to cross-arm angle bar of clamp, so jig is no longer subject to the restriction of coupling assembly length, and then can adapt to the cross-arm of different in width.In addition, because angle bar is wrapped up the enough firm of also clamping by horizontal clamp and parcel clamp, thus can guarantee that jig has stable operating state, thus the fail safe of operation improved.
In additional technical feature, clip parts are set to thread-lifting hook, can be used for changing linear string bunch of insulator.
In additional technical feature, clip parts are set to closed card, can be used for changing linear string monolithic insulator.
