The electric winching is matched with the steel wire rope and the U-shaped ring to hoist, so that the insulator sheet is easily damaged in the construction process.
The utility model has the following contents:
the utility model aims at providing a special lifting device of insulator chain hangs in transformer substation.
The above purpose is realized by the following technical scheme:
the utility model provides a special lifting device of insulator chain dangles in transformer substation, this special lifting device of insulator chain dangles in transformer substation includes four backup pads that are arranged side by side from last to lower parallel, and every is passed respectively to the both ends head of U-shaped screw rod the backup pad on stretch out the bottom behind the round hole the backup pad, the U-shaped screw rod on a plurality of fixation nut of threaded connection distribute at every the upper and lower both sides of backup pad will the backup pad centre gripping fixed, the backup pad be by two structures of having the butt joint of square board of semicircle opening and forming, the lower part of the square board that has the semicircle opening bond and have the semicircle supporting pad.
The special hoisting tool for the suspension insulator string of the transformer substation is characterized in that a round hole is formed in each of the left end and the right end of a square plate with a semicircular notch, and the diameter of each round hole is larger than that of each U-shaped screw rod.
Has the advantages that:
1. the utility model discloses can fix the device on the insulator chain that dangles, can make it protect the insulator chain that dangles in hoist and mount, prevent to damage it because hoist and mount.
The utility model discloses can realize dismantling fast and installing, distance between each backup pad is adjustable simultaneously, and the orientation of semicircle ring supporting pad can change, can be applicable to the insulator chain that dangles of different models.

The specific implementation mode is as follows:
example 1:
the utility model provides a special lifting device of insulator chain dangles in transformer substation, this special lifting device of insulator chain dangles in transformer substation includes four backup pads 4 from last to parallel arranging side by side down, and the both ends head of U-shaped screw rod 3 passes every respectively the backup pad on the round hole 7 after stretch out the bottom the backup pad, the U-shaped screw rod on a plurality of fixation nut of threaded connection 2 distribute at every the upper and lower both sides of backup pad will the backup pad centre gripping fixed, the backup pad be by two structures of 6 butt joints of square board that have the semicircle opening, the lower part of the square board that has the semicircle opening bond and have semicircle supporting pad 5.
Example 2:
according to the special hoisting tool for the suspension insulator string in the transformer substation in the embodiment 1, the left end and the right end of the square plate with the semicircular notches are respectively provided with a round hole, and the diameter of each round hole is larger than that of the U-shaped screw rod.
The hoisting method comprises the following steps: the front side and the rear side of the supporting plate on the uppermost layer are respectively welded with two lugs 1 with round holes, which can be used for hoisting, the second supporting plate and the fourth supporting plate are turned over from top to bottom, so that the semicircular supporting pads face upwards, then the supporting plate on the uppermost layer is buckled on the bottle shed shaft column above the suspension insulator string on the uppermost layer in a butt joint manner, the semicircular supporting pad on the lower part is pressed on the upper part of the insulator on the uppermost layer, the diameter of the semicircular opening of each square plate is equal to the diameter of the bottle shed shaft column of the suspension insulator string, the two square plates are buckled together to realize fixation, fixing nuts are screwed on the two ends of the U-shaped screw rod and screwed above the U-shaped screw rod, then the lower part of the U-shaped screw rod passes through the round hole of the first supporting plate and then is screwed on the U-shaped screw rod, so that the two fixing nuts clamp and fix the first supporting plate, the second supporting plate is buckled on the bottle shed shaft column between the, the semicircular supporting pad above the second layer of supporting plate is pressed on the lower part of the uppermost layer of insulator, a fixing nut is screwed on the U-shaped screw rod, then the U-shaped screw rod penetrates through the round hole of the second layer of supporting plate, then a fixing nut is screwed to clamp and fix the second layer of supporting plate, then the third layer of supporting plate and the fourth layer of supporting plate slide to clamp and fix the third layer of insulator by the third layer of supporting plate and the fourth layer of supporting plate, the sequence and the number of the fixing nuts screwed on the U-shaped screw rod are the same as those of the first layer of supporting plate and the second layer of supporting plate, so that the suspension insulator string is lifted by a steel wire rope and a lifting lug after being fixed, the semicircular supporting pad is arranged to protect the insulator while being fixed, the insulator string is prevented from being damaged, meanwhile, the whole device is easy to disassemble and assemble, the positions of the supporting plates can be changed, and (6) hoisting.
