Description

TECHNICAL FIELD

[0001] The utility model relates to bridge detection technical field, concretely is a liftable bridge pier column detection equipment. BACKGROUND

[0002] Bridge pier column is an important load-bearing part in bridge structure, responsible for supporting bridge deck and transferring load to foundation. They are usually located at both ends and middle of the bridge, playing a role in stabilizing the bridge and improving its carrying capacity. Due to the influence of traffic load, environmental factors and geological conditions, bridge pier column may have various problems during use, such as cracks, corrosion, etc. If these problems are not discovered and handled in time, it will gradually lead to the decrease of the structural strength of the pier column, and even may cause the overall safety hazard of the bridge. Therefore, in order to ensure the safety of the bridge in use, the pier column needs to be detected regularly after use to identify and evaluate potential structural defects in time, so as to take necessary repair and reinforcement measures.

[0003] The patent with publication number CN222280510U discloses a bridge pier column detection device, which comprises a pier column, a frame movably connected to the outer surface of the pier column, two sections of the frame, a rotating shaft rotatably connected between the two sections of the frame, four supports fixedly connected to the lower surface of the frame, four rotating wheels fixedly connected to the inner surface of the four supports, the rotating wheels movably connected to the side surface of the pier column, an electric motor fixedly connected to the side surface of any two supports, the rotating wheels powered by the electric motor, a pier column detection device fixedly connected to the lower surface of the frame, an air pipe fixedly connected to the upper surface of the frame, the air pipe provided with air holes, an air pump fixedly connected to the upper surface of the air pipe, the output end of the air pump in communication with the air pipe, and bristles fixedly connected to the inner surface of the frame. Through the above components, the dust and foreign matter on the surface of the pier column can be removed, keeping the surface clean to ensure that dust and foreign matter do not interfere with the normal work of the pier column detection device.

[0004] The above-mentioned prior art has certain limitations in specific use. Specifically, the position of the existing pier column detection device is fixed, which means that when the rotating wheel drives it to move up and down, the device can only detect part of the bridge pier column. In order to complete the comprehensive detection of the entire bridge pier column, the worker needs to adjust the position of the pier column detection device many times, which not only increases the time cost of detection, but also may cause errors and safety hazards in the operation process. In view of this, we propose a liftable bridge pier column detection device. UTILITY MODEL CONTENTS
