Specifically, as shown in fig. 1 to 4, the insulator replacement tool includes a support member 1, a receiver 2, and a hanger member 3.
Wherein the support 1 is configured to be connected to an installation site of the insulator 100 to be replaced; the supporting piece 2 is detachably connected to the supporting piece 1 and is connected with the insulator 100 to be replaced; the two ends of the hanging object 3 are respectively connected with the supporting part 1 and the supporting part 2, and the length of the hanging object 3 is adjustable. When an operator disassembles and assembles the insulator, firstly, the support piece 1 is connected to an installation position of the insulator 100 to be replaced, the support piece 2 is connected with the insulator 100 to be replaced, and the insulator 100 to be replaced is supported through the support piece 1 and the support piece 2, so that the operator is prevented from holding the insulator to operate, and the physical consumption of the operator is reduced; then, the fixing bolt 102 of the insulator 100 to be replaced is detached from the mounting position; finally, the supporting member 2 is separated from the supporting member 1, and the supporting member 2 and the insulator 100 to be replaced connected thereto are lowered to the ground or a designated position by the hanging member 3, thereby completing the removal of the insulator 100 to be replaced, see fig. 4. It will be appreciated that the sequence of the new insulator installation operation is reversed from the removal operation described above. The length of the hanging object 3 is adjustable, that is, when the insulator 100 to be replaced is disassembled, the supporting part 2 is connected with the supporting part 1, the length of the hanging object 3 is minimum, and the disassembled insulator can be prevented from falling suddenly, so that operators at the lower operating point are broken or injured; in the process of placing the insulator 100 to be replaced, the supporting part 2 is separated from the supporting part 1, the length of the hanging part 3 is gradually increased, and the phenomenon that the supporting part 2 and the insulator 100 to be replaced fall too fast to generate violent swing to cause the collision of the insulator 100 to be replaced can be avoided.

When disassembling the insulator 100 to be replaced, the maintenance worker needs to screw down the fixing bolt 102 first, however, the screwed-down fixing bolt 102 is easy to fall off, and the operation efficiency of the maintenance worker is seriously affected. Therefore, in order to prevent the fixing bolt 102 from falling off, the supporting member 1 is provided with the receiving groove 12, the receiving groove 12 can be sleeved outside the fixing hardware 101 at the installation position of the insulator 100 to be replaced, and when the fixing bolt 102 is screwed off, the fixing bolt falls into the receiving groove 12, thereby effectively preventing the fixing bolt 102 from falling off and being lost.
Further, referring to fig. 5 and 7, the support member 1 further includes a fixing cover plate 13, and the fixing cover plate 13 is connected to the notch of the receiving groove 12 to fix the support member 1 on the fixing fitting 101.

In this embodiment, the supporting member 2 is two supporting rods arranged at an interval, the side portions of the two supporting rods are penetrated by through holes, and one end of the binding band 21 sequentially penetrates through the two through holes and can be connected with the other end of the binding band 21 outside the insulator 100 to be replaced. It will be appreciated that the use of the tie 21 enables the insulator 100 to be replaced to be connected more firmly to the support 2. The two ends of the binding band 21 can be adhered by a magic tape or connected by a buckle, and the binding band is not limited herein.
Further, in the present embodiment, the binding band 21 is provided in plural, and the plurality of binding bands 21 are provided at intervals along the length direction of the support member 2.

The positioning pulley 11 can make the object lifting rope 31 be retracted according to a fixed track, meanwhile, the friction force of rolling friction is far smaller than that of sliding friction, the positioning pulley 11 can also make the movement of the object lifting rope 31 smoother, and protect the object lifting rope 31, and the service life of the object lifting rope is prolonged.
Specifically, referring to fig. 1, 5 and 6, the locking structure includes a gear 33, a positioning member 34 and a reset member 36, the gear 33 is coaxially and fixedly connected with the rotating shaft 32, the positioning member 34 can slide relative to the supporting member 1 to extend between any two teeth of the gear 33, and the reset member 36 is used for driving the positioning member 34 to reset. In this embodiment, the positioning member 34 is an L-shaped rod, the | portion of the positioning member 34 is slidable relative to the support member 1, and when the | portion of the positioning member 34 extends between the two teeth of the gear 33, the gear 33 is locked, thereby locking the rotation of the shaft 32. When the operator needs to rotate the rotating shaft 32, the positioning member 34 is pulled to move in a direction away from the gear 33, so that the rotation of the gear 33 and the rotating shaft 32 fixedly connected therewith can be recovered. Meanwhile, the support member 1 is further provided with a positioning block 35, when the positioning block 34 is pulled, the "-" part of the positioning block 34 is rotated, so that the "-" part can be rotated to the rear of the positioning block 35 and abutted against the positioning block 35, and the positioning block 35 can fix the position of the positioning block 34.

Optionally, the lifting member 3 further comprises a braking structure for preventing the rotation shaft 32 from rotating reversely. Further, the braking structure comprises a ratchet wheel and a pawl 37, the ratchet wheel is coaxially fixedly connected with the rotating shaft 32, and the pawl 37 is rotatably connected to the supporting member 1. The matching of the ratchet wheel and the pawl 37 can enable the rotating shaft 32 to rotate in a single direction and not to rotate reversely, so that the insulator is prevented from falling off due to misoperation of an operator. In this embodiment, the gear 33 in the locking structure is the ratchet wheel, the ratchet wheel can also drive the rotating shaft 32 to rotate, and when the positioning member 34 extends between any two teeth of the ratchet wheel, the ratchet wheel stops rotating, and the rotating shaft 32 is locked.
