▎ 摘　　要

NOVELTY - The device has a link pier (1) whose four sides are symmetrically provided with four vertical pull rods (2). The top end of link pier is transversely and symmetrically provided with two anti-overturning mechanisms (3). One end of the vertical pull rod is connected with a foundation and the other end of vertical pull rod is connected with the anti-overturning mechanism. The top end of link pier is located between the two anti-overturning mechanisms. A top end of a supporting seat (6) and the anti-overturning mechanism are connected with a box beam (7). The top end of box beam is provided with a support. The support is provided with a high definition camera and LED lamps. The high definition camera and LED lamps are electrically connected with the anti-overturning mechanism. A guide rail is coated with graphene material. USE - Used as anti-overturning and safety pre-warning device of existing single-column pier link. ADVANTAGE - The device: has simple structure, good durability, convenient installation and maintenance; adjusts the position and jacking force of jack through the driver of control center; provides the additional anti-overturning moment for the box beam; ensures the operation safety of the single-column pier link; and reduces the occurrence of safety accidents. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of the anti-overturning and safety pre-warning device of existing single-column pier link along the direction of link after installation.
