Swing type damping device on top of single pipe tower

Abstract

The invention relates to the field of electric power communication facilities, and particularly discloses a swing type damping device on the top of a single pipe tower. The swing type damping device comprises the single pipe tower and is characterized in that a swinging body is suspended on the top inside the single pipe tower by a rope, a round of damping baffles is arranged around the swinging body, a supporting plate is arranged under the damping baffles for supporting the damping baffles, and the supporting plate is fixed on the wall of the single pipe tower; and springs which are distributed radially are arranged between the damping baffles and the wall of the single pipe tower. The horizontal displacement of the tower can be reduced under wind load or seismic load; when the amplitudeof oscillation is large, a swinging column strikes against a damping system so as to avoid colliding directly with the side wall of the single pipe tower, and in addition, the springs and the swing column together can produce a force opposite the movement direction of the single pipe tower to the single pipe tower, so as to realize the effect of reducing the displacement.

Description

technical field [0001] The invention relates to the field of electric power communication facilities, in particular to a swing-type damping device at the top of a single-pipe tower. Background technique [0002] Single-pipe towers are mainly used as transmission towers and communication towers, which are towering structures. Under the action of wind load and earthquake load, the horizontal displacement of the top of the tower is relatively large. From the point of view of the use function, there are the following defects: when used as a transmission tower, the large horizontal displacement may cause the power line connected to it to be broken; when used as a communication tower, the large horizontal displacement may cause the Antennas and signaling devices placed on it are thrown off, which can lead to failure of power transmission and communication systems; [0003] The invention patent "New Single Tube Tower" (CN 205189482 U) proposes to put a steel ball on the top of th...

Problems solved by technology

From the point of view of the use function, there are the following defects: when used as a transmission tower, the large horizontal displacement may cause the power line connected to it to be broken; when used as a communication tower, the large horizontal displacement may cause the Antennas and signaling devices placed on it are thrown off, which can lead to failure of power transmission and communication systems;

If the steel ball is too small and light, the shock absorption effect cannot be achieved. If it is too large, it will easily collide with the single-tube tower wall during the vibration process and cause its damage. This method is difficult to achieve the shock absorption effect.
