Description

Bridge pier protector Technical Field The utility model relates to the technical field of bridge protection devices, in particular to a bridge pier protection device. Background The bridge is used as an important tie for road intercommunication, especially a mountain bridge, is often impacted by mountain rolling stones and broken stones, and has a trend of increasing year by year. The rolling stones and broken stones not only often act on the bridge piers by virtue of strong impact energy, but also influence bridge body vibration when the bridge piers are impacted, and influence the service life and safety of the bridge. In order to solve the problem, the prior art generally sets up the anticollision protective sheath (like patent CN215329310U of publication No. that pours annular concrete layer outside the pier) outside the pier, and although it can solve the anticollision problem, because the barren rock strikes pier direction relatively fixed, consequently always strike the same direction of anticollision protective sheath, long-time use can lead to the anticollision protective sheath to receive the failure of impact part, and anticollision protective sheath life is low. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide the bridge pier protection device, and the rotatable anti-collision protection sleeve is arranged to rotate when the anti-collision protection sleeve fails at the part which is impacted for a long time, so that the part which is not impacted by the anti-collision protection sleeve rolls downwards in the impact direction of stones, and the service life of the anti-collision protection sleeve can be greatly prolonged. The aim of the utility model is realized by the following technical scheme: the utility model provides a bridge pier protector, includes the crashproof protective sheath of setting in the pier outside, crashproof protective sheath rotates with ground through rotary component and is connected, rotary component is used for driving crashproof protective sheath and rotates along its circumference for the pier. Further, the rotating assembly comprises an inner supporting ring plate, an outer supporting ring plate and a rotating ring plate, wherein the inner supporting ring plate is coaxially arranged outside the bridge pier and fixed with the ground, and the outer supporting ring plate is coaxially arranged outside the inner supporting ring plate and fixed with the ground; The rotating ring plate is coaxially arranged outside the bridge pier, and is rotationally connected to the inner supporting ring plate and the outer supporting ring plate through a transmission piece; the anti-collision protective sleeve is arranged on the ground on the top surface of the rotating ring plate. Further, the transmission member includes a plurality of first rollers and a plurality of second rollers fixed with the rotating ring plate, the plurality of first rollers are uniformly arranged along the inner support ring plate, and the plurality of second rollers are uniformly arranged along the outer support ring plate. Further, the rotating ring plate comprises a plurality of support frames and a plurality of support plates, wherein the support frames are isosceles trapezoids, the support frames form an annular framework structure, the support plates are isosceles trapezoid plates and are adapted to the support frames, and the support plates are fixedly connected with the support frames. Further, the support plate is fixed with the support frame through bolts. Further, the supporting plate is welded and fixed with the supporting frame. Further, two pin holes are further formed in the outer support plate, pins are arranged in the pin holes, one second roller is located between the two pins, and the two pins are used for limiting the second roller to move along the circumferential direction of the outer support ring plate. Further, the anti-collision protective sleeve is made of concrete or rubber materials. The beneficial effects of the utility model are as follows: According to the utility model, the rotatable anti-collision protective sleeve is arranged, and the anti-collision protective sleeve rotates when the part of the anti-collision protective sleeve, which is impacted for a long time, fails, so that the part of the anti-collision protective sleeve, which is not impacted, faces downwards to the impact direction of the rolling stone, and the service life of the anti-collision protective sleeve can be greatly prolonged.
