Description

Technical Field

[0001] This utility model belongs to the field of railway bridge technology, and more specifically, it relates to a rapid detection device for defects in railway bridge piers and abutments. Background Technology

[0002] As the core supporting components for train operation, the health of railway bridge piers and abutments directly affects traffic safety and the service life of the project. Common types of defects include longitudinal and circumferential cracks in the pier body, cracks at the connection between the pier and the support plate, and cracks at the top of the pier. These damages often stem from tensile stress or uneven settlement of the foundation. If effective measures are not taken in time, they may cause lateral vibration amplitudes to exceed safety standards, thereby threatening the stability and safety of the entire structure. Therefore, relevant personnel must conduct meticulous inspections regularly. However, due to the large design height of some bridge piers and abutments, relying solely on manual visual inspection has limitations, and some minute cracks are easily missed, creating blind spots in the inspection. For piers located in water or deep in canyons, surface defect inspection faces many inconveniences and challenges. Utility Model Content

[0019] like Figure 3 As shown, the pressurization control mechanism 3 includes: a fixed rod 301, a threaded control rod 302, and a motor housing 303; the fixed rod 301 is a cuboid structure with a groove on its surface, and the support box 201 is fixedly installed inside the support box 201; one end of the threaded control rod 302 is rotatably inserted into the groove of the fixed rod 301; a motor is installed inside the motor housing 303, and the motor housing 303 is installed on one side of the support box 201 and connected to the threaded control rod 302.

[0020] like Figure 3 As shown, the pressurization control mechanism 3 also includes: a drive plate 304, a pusher 305, and a rubber sealing ring 306; the drive plate 304 has a T-shaped structure, and the drive plate 304 is slidably inserted into the groove of the fixed rod 301 and threadedly connected to the threaded control rod 302. The rotation of the threaded control rod 302 can control the sliding of the drive plate 304; one side of the pusher 305 is inserted into the support box 201 and fixedly connected to the drive plate 304, and the other end of the pusher 305 is inserted into the bearing tube 401; the rubber sealing ring 306 is fixedly installed on the surface of the pusher 305.

[0021] like Figure 5 As shown, the unidirectional flow assembly 404 further includes: a fixed support ring 4041, an elastic telescopic support rod 4042, and a plug 4043; the fixed support ring 4041 is fixedly connected to the carrier pipe 401; one side of the elastic telescopic support rod 4042 is fixedly connected to the carrier pipe 401 through a square plate; the plug 4043 is fixedly connected to the elastic telescopic support rod 4042, and the plug 4043 is inserted into the liquid outlet of the fixed support ring 4041.

[0022] The specific usage and function of this embodiment are as follows: In this invention, when inspecting the surface defects of bridge piers, inspectors can stand on the bridge and remotely control a drone 1 to fly along the pier surface and take pictures, performing a detailed inspection. When defects are found, a laser indicator 403 illuminates and indicates the location of the pigment mark, and the motor inside the remotely controlled motor box 303 starts. The motor controls the rotation of the threaded control rod 302. During the rotation, the threads on the surface of the threaded control rod 302 can control the sliding of the drive plate 304 and the pusher 305. Since the other end of the pusher 305 slides into the bearing tube 401, the sliding of the pusher 305 can push the pigment compression flow inside the bearing tube 401. The movement of the stopper 4043 causes the elastic telescopic support rod 4042 on one side of the stopper 4043 to retract, extruding the pigment from the outlet of the bearing pipe 401 and spraying it onto the surface of the pier to mark the damaged area. Since the top of the delivery pipe 402 is connected to the storage tank 202 through a liquid one-way valve, the pigment will not enter the storage tank 202 through the delivery pipe 402 when the pusher 305 slides and pushes the pigment delivery. As the pusher 305 slides outward, it generates a suction force, which can draw the pigment in the storage tank 202 into the bearing pipe 401 through the one-way valve, completing the automatic injection of pigment. The pigment in the storage tank 202 is then injected through the funnel 204.
