spring 43, make vibration sensor 12 and tower cylinder body 2 indirect connection, when vibration sensor 12 monitors that tower cylinder body 2 vibrates comparatively acutely, start electric telescopic handle 21 and drive the inner chamber of rubber piece 24 indentation mounting groove 20, remove the connection between connecting plate 7 and wire rope 6, in addition electric telescopic handle 21's output drives to move and detains 23 and remove and make connecting plate 7 and backup pad 8 between connecting plate 7 The connection is also released, the double-shaft motor 4 is started to drive the winding drum 5 to rotate, the supporting plate 8 is driven to independently descend for a certain distance through the steel wire rope 6, then the servo motor 26 is started to drive the first helical gear 17 to rotate, the transmission shaft 28 and the first straight gear 31 are driven to rotate through the meshing between the first helical gear 17 and the second helical gear 29, the first straight gear 31, the second straight gear 33 and the third straight gear 39 are driven to rotate through the transmission among the gear transmission belt 40, the second straight gear 33 and the third straight gear 39 are driven to rotate through the transmission among the first straight gear 31, the second straight gear 33 and the third straight gear 39, at the moment, one end of the first round head pin 49 is inserted into the inner cavity of the first crescent tooth groove 46 to drive the first threaded rod 32 to rotate along with the second straight gear 33, the rotation of the first threaded rod 32 drives the first supporting column 35 to extend outwards, and at the moment, one end of the second round head pin 53 is inserted into the inner cavity of the second crescent tooth groove 51 to drive the second threaded rod 38 to rotate along with the third straight gear 39, the rotation of the second threaded rod 38 drives the second supporting column 37 to extend outwards, because the inner wall of the tower body 2 is an inclined surface, the first supporting column 35 drives the first anti-slip block 19 to contact with the inner wall of the tower body 2 first, when the first anti-slip block 19 contacts with the inner wall of the tower body 2, the first supporting column 35 can not move outwards any more, at this time, one end of the first round-head pin 49 is separated from the inner cavity of the first crescent 46, so that the second spur gear 33 rotates, in addition, the third spur gear 39 continues to drive the second supporting column 37 to move outwards, when the second anti-slip block 18 is also abutted against the inner wall of the tower body 2, one end of the second round-head pin 53 is separated from the inner cavity of the second crescent 51, so that the third spur gear 39 rotates, at this time, the servo motor 26 is turned off, the supporting plate 8 is fixed in the inner cavity of the tower body 2 through the first supporting column 35, the second supporting column 37, the first anti-slip block 19 and the second anti-slip block 18, thereby strengthen tower section of thick bamboo body 2's intensity, start electric telescopic handle 21 at last and drive rubber block 24 and stretch into the inner chamber that the rope hole 14 was crossed to the second again and support wire rope 6 for be connected between wire rope 6 and the connecting plate 7, can.
