Description

Bridge deviation detection device Technical Field The utility model relates to the technical field of detection devices, in particular to a bridge deviation detection device. Background The bridge is displaced due to the influence of various factors on the structure of the bridge in the using process. Therefore, bridge displacement detection becomes a crucial task. The bridge displacement detection is to comprehensively detect all parts of the bridge, including the main body structure, auxiliary facilities, bridge deck system and the like of the bridge, so as to evaluate the overall performance and safety of the bridge. When the bridge is subjected to displacement detection operation, a bridge deviation detection device is needed. The patent with publication number CN222689056U provides a bridge deviation detecting device, which is only suitable for detecting when the displacement is large because it relies on the linear displacement of the guide rod, and if the bridge is slightly displaced, the accuracy of the detecting result is poor and even the detection of the small displacement cannot be performed. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides a bridge deviation detection device, which can amplify the micro displacement of a bridge by arranging a detection assembly so as to accurately reflect the micro deviation of the bridge. The aim of the utility model is realized by the following technical scheme: The bridge deviation detection device comprises a support, wherein the support is fixedly arranged on a bridge pier, a plurality of groups of detection assemblies are arranged on the support, the detection assemblies comprise a first liquid pipe and a second liquid pipe, the bottoms of the first liquid pipe and the second liquid pipe are communicated through a communicating pipe, liquid is arranged in the first liquid pipe and the second liquid pipe, a displacement piece capable of axially moving along the first liquid pipe is arranged in the first liquid pipe, and the top end of the displacement piece is connected with the bottom surface of the bridge; when the displacement member is used for shifting the bridge, the displacement member extrudes the liquid in the first liquid pipe into the second liquid pipe; The diameter of the second liquid pipe is smaller than that of the first liquid pipe. Further, the liquid is water. Further, the displacement member comprises a piston rod, and a piston matched with the first liquid pipe is arranged at the bottom end of the piston rod. Further, the diameter ratio of the second liquid pipe to the first liquid pipe is 1/5-1/2. Further, the bracket is made of stainless steel material. Further, the support includes the arc and sets up the straight board at arc both ends, the arc with the pier is fixed, detection assembly sets up on straight board.
