when the upper beam 1-1 and the lower beam 1-2 move relatively, the rack 2 drives the gear 4 to rotate; the gear 4, the first bevel gear 5 and the vertical rod are fixedly connected, and when the gear 4 rotates, the vertical rod and the first bevel gear 5 rotate;
the first bevel gear 5 is matched with the second bevel gear 7, and the first bevel gear 5 drives the second bevel gear 7 to rotate when rotating, so that the horizontal rod can rotate around the central shaft;

The vertical rotary damper further comprises: a box body 9;
the box body 9 is arranged on the lower beam 1-2, and the vertical rod and the horizontal rod are positioned inside the box body 9; a socket is arranged on the lower surface of the upper flange of the upper beam 1-1, and the top end of the side plate of the box body is inserted into the socket 12 so as to seal the box body;
the horizontal rods and the lower beam 1-2 are fixed through a plurality of first supporting rods 10, bearing structures are arranged at the top ends of the first supporting rods 10, and the horizontal rods penetrate through the bearing structures at the top ends of the first supporting rods 10;
a plurality of cantilever rods are arranged on two side plates of the box body 9; a bearing structure is arranged at the end part of the cantilever rod; the vertical rods 3 are connected through a bearing structure of a cantilever rod of the side plate of the box body.
Viscous damping fluid is arranged in the box body.
The working method of comparative example one is: the relative motion between the upper beam 1-1 and the lower beam 1-2 is transmitted through the vertical rod, the horizontal rod and the like to drive the rotary blades 8 to rotate in the box body 9, and when the rotary blades 8 move in the viscous damping fluid, a large amount of heat energy can be generated, so that the seismic energy is converted into the heat energy.
The first comparative example has the advantages that the first comparative example is designed for the T-shaped beam, the space between the ventral surface and the lower surface of the upper flange of the T-shaped beam is fully utilized to arrange the socket so as to seal the box body, and meanwhile, the displacement of the top end of the side plate of the box body is limited (the displacement can only be carried out along the longitudinal direction of the beam);
the space between the ventral surface of the T-shaped beam and the lower surface of the upper flange is utilized to arrange the insection-gear (the gear can only be arranged to rotate horizontally).

Namely, the second embodiment adjusts the position of the second bevel gear in the first embodiment so as to adjust the rotational displacement of the horizontal rod.
Another improvement of the second embodiment is that, as shown in fig. 8, the side panel is designed in a circular ring shape, and the radius of the outer ring is equal to the length of the top end of the rotary blade 8 from the central axis of the horizontal rod; and when the radius of the inner circle is too large, the following steps are faced: the rubber layer contact area of the side panels in the first vertical rotary damper and the second vertical rotary damper is too small.
Therefore, the second embodiment adopts the design as shown in fig. 11, the horizontal rods in the first vertical rotary damper and the second vertical rotary damper are at the same height (or not at the same height);
