In the prior art, no clamp for replacing the linear insulator string of the steel pipe pole of the power transmission line in an electrified way is provided, at present, no clamp for replacing the linear insulator string of the steel pipe pole in an electrified way is provided for domestic electric power tool manufacturers, and if insulator flashover occurs, the insulator can not be replaced in an electrified way in time, and the normal operation of the line is seriously threatened. At present, the steel pipe pole of the power transmission line is necessary to develop the technical research of replacing the suspension insulator clamp of the steel pipe pole of the power transmission line aiming at the actual safe operation and maintenance condition of the steel pipe pole of the power transmission line aiming at the objective problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a fixture for replacing insulators of a steel pipe pole of a power transmission line, which is reasonable in structure, safe and reliable, and can safely and reliably replace a linear insulator string of a 66kV steel pipe pole line in a live line running state.
The technical scheme of the utility model is as follows: the fixture for replacing the insulator of the steel pipe rod of the power transmission line is characterized by comprising a cross beam, wherein two ends of the cross beam are provided with U-shaped openings, two side arms of each U-shaped opening are provided with openings with upward openings, the openings are vertical to the cross beam, and the bottom of each opening is semicircular; two spaced suspender groove holes are arranged on the beam surface; the cross beam is also provided with a pair of hanger rod hooks which are hung at the middle part of the cross beam, the hanger rod hook is a hanger rod with a flat hook at one end, and a shoe-shaped nut is screwed at the other end.
The utility model has the advantages that: the linear insulator string of the 66kV steel pipe pole line can be safely and reliably replaced in a live line running state, and each operation is carried out for 0.75 hour/4 people; the fixture has the characteristics of light weight, simple and reasonable structure, safe and reliable use and flexible operation, can simplify the working procedure by matching with the adjustable insulating hanger rod to lift the insulator string, achieves the expected targets in time, manpower and safe reliability, and solves the problem that no special fixture is used for replacing the suspension insulator of the steel pipe rod of the 66KV power transmission line.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of the structure of the present invention in use.
Fig. 2 is a schematic front view of the present invention.
Fig. 3 is a schematic top view of fig. 2.
Detailed Description
Referring to fig. 1-3, the part names are as follows: crossbeam 1, U type opening 2, opening 3, jib recess hole 4, jib 5, ingot nut 6, steel-pipe pole cross arm 7, couple 8, wire 9, insulator 10.
Referring to fig. 2 and 3, the fixture for replacing the insulator of the steel pipe pole of the power transmission line comprises a cross beam 1, wherein two ends of the cross beam 1 are provided with U-shaped notches 2, two side arms of each U-shaped notch 2 are provided with notches 3 with upward openings and vertical to the cross beam 1, and the bottoms of the notches 3 are semicircular (used for lapping pin shafts and hanging hooks 8); two spaced boom recessed holes 4 (one elongated hole) are provided in the face of the beam 1.
Referring to fig. 1, the beam 1 is also provided with a pair of hanger rod hooks which are hung at the middle part of the beam, the hanger rod hook is a hanger rod 5 with a flat hook at one end, and a shoe-shaped nut 6 is screwed at the other end.
The tool is characterized in that a cross beam 1 (a fixture main body) is placed at the head of a cross arm 7 of a steel pipe pole, the cross beam 1 is fixed through two suspension rods 5, and a wing nut 6 is locked. The two sides are matched with a hook 8. In the figure 1, the lower end of the right hook 8 is hung on the lead 9, and the upper end of the hook 8 is placed in the clamp notch 3. When the hook 8 is adjusted to a certain height, the load in the vertical direction of the lead 9 can be transferred, the purpose of replacing the insulator 10 can be realized after the load is transferred, and the requirement of replacing the suspension insulator of the steel pipe pole of the 66-kilovolt power transmission line is met.
The foregoing description is only exemplary of the utility model and is not intended to limit the spirit of the utility model.
