The working flow of the invention is as follows: in the initial state, the two rings A5 are separated, each ring A5 having a half ring gear 9, a half ring B31 and a half ring D33. The distance between the inner hexagonal sleeve 23 on each annular sleeve A5 and the central axis of the annular sleeve A5 is equal and greater than the distance between the connecting hole 3 on the steel pipe rod 1 and the central axis of the steel pipe rod 1. The stopper rod a25 in each guide rod 18 is in a state of restricting the bolt B46 entering the inside of the hexagon socket 23. Spring a26 is in a compressed state and spring B43 is in a natural state. The scroll spring 40 is in a compressed state, the deflector rod C39 is abutted against the corresponding swing limiting block 41 under the action of the scroll spring 40, the tail end of the swing rod 54 swings out of the transmission groove 50 of the deflector rod D49 under the action of the plate spring 55, and the sharp corner end of the limiting rod B52 is contracted in the sliding groove C51.
When the steel pipe rod 1 of the butt joint fixing overhead line is required to be installed by using the invention, the matched invention is selected, so that the loop A5 of the invention is matched with the butt joint flange 2 on the steel pipe rod 1, two loops A5 lifted by a crane are nested on the butt joint flange 2 of the two steel pipe rods 1 which are well butt-jointed by one person, and the two loops A5 are butt-jointed and fixed by the bolts A45 to form a finished circular loop A5. Then, each inner hexagonal sleeve 23 is located between two corresponding adjacent reinforcing ribs on the butt flange 2, the radius of the inner hexagonal sleeve 23 coincides with the radius of the connecting hole 3 on the butt flange 2, the bolts A45 on the bolt ring sleeve A5 are further tightened, the ring sleeve A5 is tightly nested on the flange 2, and then the half ring gear 9 and the ring sleeve D33 on the two half ring sleeves A5 are in butt joint and fixed through the bolts A45.
Next, a bolt B46 is inserted into each hexagon socket 23, and the bolt B46 stays suspended in the hexagon socket 23 under the limit of the corresponding limit rod a 25. Then, the gear ring 9 is rotated, the gear ring 9 drives the guide rod 18 in each guide sleeve 12 to move radially to the connecting hole 3 through the gear A17, the rotating shaft A14 and the gear B16, and the guide rod 18 drives the inner hexagonal sleeve 23 and the bolt B46 in the inner hexagonal sleeve 23 to move above the connecting hole 3 through the ring sleeve B20 which is in rotary fit with the guide rod 18. At the same time, the shift lever a27 on the limit lever a25 moves in the trigger groove 13 of the inner wall of the guide sleeve 12.

When the screw rod part of the bolt B46 is completely opposite to the connecting hole 3, the limit rod A25 just completely removes the limit of the bolt B46, the bolt B46 vertically falls into the connecting holes 3 on the two flanges 2 under the action of dead weight and starts to be in threaded fit with the connecting holes 3, and the nut and most of the screw rod part of the bolt B46 are still positioned in the inner hexagonal sleeve 23.
Then, the driving lever D49 is held by hand, so that the swing rod 54 swings into the transmission groove 50, the plate spring 55 is compressed, the driving lever D49 drives the tip of the limit lever B52 to be inserted into the tooth slot 34 on the ring sleeve D33 through the connecting rod 53, and the relative positions of the sliding sleeve 47 and the ring sleeve D33 are fixed. Then, the driving lever D49 is pulled forcefully around the central axis of the ring sleeve D33, the driving lever D49 drives the ring sleeve D33 to rotate relative to the ring sleeve A5 through the sliding sleeve 47, the driving lever B30 on each inner hexagonal sleeve 23 is driven by the ring sleeve D33 through the driving lever C39 thereon, the driving lever B30 drives the inner hexagonal sleeve 23 to rotate relative to the ring sleeve B20 through the ring sleeve C29 and the unidirectional ring 28, at this time, the unidirectional ring 28 plays a unidirectional driving role, the inner hexagonal sleeve 23 drives the bolt B46 to screw into the inner thread of the connecting hole 3, and the spring B43 for restoring the relative rotation of the ring sleeve C29 and the ring sleeve B20 is stretched.
With the rotation of the inner hexagonal sleeve 23, the shift lever C39 and the shift lever B30 are relatively misplaced, and when the shift lever B30 and the shift lever C39 are completely misplaced, the ring sleeve C29 is rotationally reset relative to the inner hexagonal sleeve 23 under the reset action of the spring B43, and at this time, the unidirectional ring 28 performs the overrunning action without preventing the rotational reset of the ring sleeve C29.
Then, by pushing the shift lever D49 reversely, the shift lever D49 drives the collar D33 to rotate reversely relative to the collar A5 through the sliding sleeve 47, and during the rotational reset of the collar D33, the shift lever C39 interacts with the shift lever B30, and since the elastic coefficient of the spring B43 is much larger than that of the volute spring 40, the shift lever C39 swings under the action of the shift lever B30, and the shift lever B30 does not swing under the action of the spring B43. When the deflector rod C39 passes over the reverse direction and passes over the deflector rod B30, the deflector rod C39 can return instantly under the reset action of the volute spring 40 to reset and re-prop against the swing limiting block 41.
Then the driving rod D49 is pulled by force, the driving rod D49 drives the annular sleeve D33 to rotate through the sliding sleeve 47, the annular sleeve D33 drives the driving rod C39 to drive the driving rod B30, and the driving rod B30 drives the bolts B46 in the inner hexagonal sleeve 23 to continuously screw into the connecting holes 3 of the flange 2 again through a series of transmission. In this way, the ring sleeve D33 is reciprocally operated, so that the inner hexagonal sleeve 23 completely and tightly screws the bolt B46 into the connecting hole 3, and the bolt B46 is finally just separated from the inner hexagonal sleeve 23 axially, thereby realizing that a single person can complete the connection and fixation of the butt flanges 2 on the two steel pipe rods 1.
After the connection and fixation of the butt flanges 2 on the two steel pipe rods 1 are completed, the gear ring 9 is manually reversed, the gear ring 9 drives the inner hexagonal sleeve 23 to reset through a series of transmission, and the limiting rod A25 in each guide rod 18 enters the inner hexagonal sleeve 23 again under the reset action of the spring A26 and restores the limiting state of the limiting rod A to the bolt B46.
Then, the two half ring gears 9 and the two half ring sleeves D33 are respectively rotated to the respective half ring sleeves A5, the bolts a45 are detached to complete the separation of the two half ring sleeves D33, the two half ring sleeves D33 and the two half ring sleeves A5, and the two half ring sleeves are lifted down by a crane. In the whole process, only one person is needed to finish on the step ladder of the steel pipe pole 1, a second person is not needed to assist through the crane to finish the butt joint fixation of the two steel pipe poles 1, the installation efficiency is high, and meanwhile potential safety hazards of auxiliary personnel on the crane are avoided.
The ring sleeve A5 in the invention is matched with the steel pipe rod 1 with the corresponding diameter.
In summary, the beneficial effects of the invention are as follows: according to the invention, only one person can complete effective installation and pre-tightening of all bolts on the flange 2 on the thicker ladder of the steel pipe pole 1, the installation efficiency is high, the potential safety hazard of auxiliary personnel on a crane is avoided, and the construction is safe. The invention has simple structure and better use effect.
