The riser 63 is provided to facilitate the connection and force transfer between the first strand 31 and the card 21.

In particular, the tower body is substantially in the shape of a rectangular frustum, the pair of first mounting sides is a pair of side surfaces of the tower body, and the pair of second mounting sides is another pair of side surfaces of the tower body.

When strong wind such as typhoon comes, the power is cut off in advance (only the high-voltage circuit of the section is cut off during the typhoon, other standby power supplies are started, so that the height of the electric power iron tower is reduced for avoiding the iron tower from being damaged), and then the bolts between the clamping plates 21 and the upper positioning plate 111 are disassembled. Before the dismantling, the winch 30 should be started to lift the cross frame 20, so as to ensure safety and facilitate the dismantling of bolts. The number of the crossbars 20 in the figure is 2, and the technical scheme can also be designed for 3 pairs of crossbars 20; when the cross frame 20 is lowered, when the cross frame 20 at the lowest side falls on the upper surface of the stop plate 125, the other cross frames 20 also reach the predetermined position, and the lower connector 332 falls on the seat body supporting plate 341 of the card seat 34 at this time, which is calculated before installation. At this time, the through hole of the clamping plate 21 is aligned with the through hole of the lower positioning plate 124, and then the clamping plate 21 and the lower positioning plate 124 are manually fastened by bolts. In the lowering process, the electric wires, the fittings and the like are in an uncharged state and are lowered along with the cross frame 20.

It should be noted that the height of the lower positioning plate 124 is also calculated, and the electric wires between the two electric power towers are not contacted with the ground, so as to avoid the friction damage of the electric wires after contacting with the ground, based on the electric wires and the non-contact ground; meanwhile, a warning measure should be taken to avoid the contact of people with the electric wire. After the strong wind is over, the cross frame 20 is lifted to the upper positioning plate 111 through the winch 30 to be connected with the upper positioning plate 111 in a bolt fastening mode, and normal electric power operation can be continued after the power is turned on again. By the operation, the electric iron tower is prevented from being blown down by strong wind, the blown-down electric wire can contact the ground and is difficult to avoid damage, and the blown-down electric iron tower is dismantled and rebuilt, consumes time and labor. Therefore, the electric iron tower can save the repair cost and avoid electric accidents; meanwhile, the electric iron tower is of an angle steel structure, the required motor driving force does not need to be very large, the whole structure is not complex, and the cost is not increased too much compared with the original structure.

After the cross frame 20 is lowered to the lower tower body 12, the transverse driving motor 354 is started, the rack 352 drives the upper connector 331 clamped in the through groove 353, the upper connector 331 is separated from the lower connector 332, and therefore the first section of rope 31 and the second section of rope 32 are separated, and the situation that the lifting rope of the winch 30 is loose after the upper tower body 11 is turned over is avoided. It should be noted that the upper connector 331 and the lower connector 332 are engaged with each other by a dovetail groove. It should be noted that, the width of the through groove 353 of the rack 352 is greater than the width of the upper connector 331, the side wall of the upper connector 331 is concavely provided with an anti-disengaging slot, two sides of the end of the through groove 353 are provided with anti-disengaging projections, and the rack 352 after horizontal translation connects the anti-disengaging projections to the anti-disengaging slot, so that the upper connector 331 can be connected to the through groove 353 after the upper tower body 11 is turned over.

When the upper connector 331 and the lower connector 332 which are separated need to be butted again, the rack 352 drives the upper connector 331 to reset, after the upper connector 331 and the lower connector 332 are clamped, the transverse driving motor 354 rotates reversely for a certain angle, the rack 352 moves reversely for a certain distance, and the anti-falling convex block falls off from the anti-falling clamping groove.

When the upper connecting head 331 and the lower connecting head 332 are disengaged, the second driving gear 42 is started to rotate, the second driving gear 42 drives the timing belt 41 to rotate, and when the timing belt 41 starts to start, the external tooth section 43 is a small distance away from the driven gear 113, and the small distance makes the external tooth section 43 not engage with the driven gear 113 at this time. Referring to fig. 4, 5, 9 and 10, for example, when it is needed to drive the upper tower 11 to rotate to the right, the second driving gear 42 is started to drive the timing belt 41 to rotate counterclockwise, at this time, the lower layer of the timing belt 41 moves to the right, at this time, the right pulling rope 123d is loosened, the left pulling rope 123d is tensioned and drives the locking rod 123a to rotate around the pivoting rod 123b, so that the round rod 112 in the left slot portion 122 leaks out, and the round rod 112 in the right slot portion 122 continues to be locked in the support base 121. The second driving gear 42 continues to drive the timing belt 41 to rotate counterclockwise, at this time, the right external tooth segment 43 engages with the right driven gear 113, and the driven gear 113 rotates clockwise, so as to drive the upper tower body 11 to rotate around the right round rod 112 relative to the lower tower body 12 until the tower top plate 114 of the upper tower body 11 abuts against the ground, at this time, the rotation of the second driving gear 42 is stopped. In the opposite process, when the lowered upper tower body 11 needs to be lifted, the second driving gear 42 is driven to rotate clockwise, the external tooth section 43 drives the right driven gear 113 to rotate anticlockwise, and the driven gear 113 drives the upper tower body 11 to rotate anticlockwise around the right round rod 112 until the upper tower body 11 is lifted to the lower tower body 12; in this process, the lock lever 123a on the left side rotates under the torque action of the torsion spring 123e, and the lock lever 123a is not closed to the corresponding stopper 121a before the left round bar 112 completely falls into the left groove 122; the synchronous cog belt 41 continues to rotate clockwise, at this time, the right outer cog section 43 disengages from the right driven gear 113, and the lower synchronous cog belt 41 continues to move leftward until the left lock lever 123a closes the left round bar 112 into the support base 121.

It should be noted that the upper tower body 11 of the present invention can be rotated to the left or right by the driving of the rotary driving assembly. Judging the rotation direction of the upper tower body 11 needs to judge the blowing direction of the strong wind in advance, the wind direction is approximately from left to right, then the upper tower body 11 is lowered to the right side of the lower tower body 12, the lower tower body 12 is in the windward side, the upper tower body 11 is hidden at the rear side of the lower tower body 12, because the foundation of the lower tower body 12 is more stable, and meanwhile, when the strong wind comes from left to right, the upper tower body 11 can be supported at the rear side of the lower tower body 12, so that the tower body is further stabilized. If the wind direction is substantially right and left, the upper tower 11 is lowered to the left of the lower tower 12.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
