Description

Technical Field

[0001] This utility model relates to the field of municipal bridge inspection technology, specifically to a pier inspection device that is easy to install quickly. Background Technology

[0002] A bridge is a structure that crosses obstacles such as rivers, valleys, and roads, playing a crucial role in many fields such as transportation and water conservancy. The main structural components of a bridge include the bridge deck, main beams, and piers. Piers are an important part of the bridge's supporting structure, responsible for bearing the bridge's vertical loads and horizontal forces. Bridge pier inspection is a key step in ensuring the safety, durability, and service life of a bridge structure.

[0003] Ultrasonic testing utilizes the propagation characteristics of ultrasonic waves in concrete to detect internal defects in piers. When ultrasonic waves encounter defects in concrete, such as voids or looseness, their propagation speed, amplitude, and waveform change. Inspectors can use these changes to determine the location and size of internal defects. However, the inventors discovered the following problems with existing technologies during the development of this invention:

[0004] 1. Existing ultrasonic testing equipment is inconvenient to connect and install with the pier section. During testing, staff still need to lift the instrument with one hand and hold the testing probe with the other hand to walk around the pier, which cannot achieve fully automatic testing.

[0005] 2. When the operator holds the probe for inspection, if the operator's operation is unstable during the walking inspection, there will be a gap between the probe and the surface of the pier. The gap will be large or small and unstable, which will affect the accuracy of the final inspection data. Utility Model Content

[0006] The purpose of this utility model is to provide a pier detection device that is easy to install quickly, in order to solve the problems mentioned in the background art, such as the inability of the detector to quickly connect and install with the pier, the inability to automatically detect, and the difficulty in controlling the interval between the probe and the pier during the detection process. To achieve the above objective, this utility model provides the following technical solution: a pier detection device that is easy to install quickly, comprising an ultrasonic tester, a drive assembly mounted on the back of the ultrasonic tester, an adjustment assembly mounted on one side of the drive assembly, and an assembly assembly provided on one side of the drive assembly.

[0007] The drive assembly includes a fixed frame, a rotating shaft rotatably connected to one side of the fixed frame, an output shaft of a first motor mounted at one end of the rotating shaft, a pulley provided on the surface of the rotating shaft, and limit blocks rotatably connected to both ends of the rotating shaft.

[0008] The adjustment assembly includes a support rod, a telescopic rod welded to the top of the support rod, a disc welded to the other end of the telescopic rod, a circular tube welded to the surface of the disc, and a lead screw threaded to one end of the circular tube.

[0009] The assembly includes a first gear, a second gear meshing with one side of the first gear, a shaft welded to the inner walls of the first gear and the second gear, a slide rail welded to the top of the shaft, and an output shaft of a second motor mounted on the bottom of the shaft.

[0010] More preferably, the slide rail and the shaft are set as a group, and there are two groups in total, and the cross-section of the slide rail is arc-shaped.

[0011] In a further preferred embodiment, the shaft is configured to rotate via a second motor, and the bottom of the slide is provided with a steel pipe and a counterweight.

[0012] In a further preferred embodiment, a probe is inserted into the top of the ultrasonic tester, the outer shell of the probe is bonded to the inner wall of the disc, and the central axis of the telescopic rod is perpendicular to the central axis of the support rod.

[0013] More preferably, the top of the lead screw and the support rod are connected by a rotating connection.

[0014] More preferably, the side of the slide is provided with a groove, and the limiting block forms a slide rail structure with the slide through the groove.

[0015] More preferably, the pulley is embedded in the upper surface of the slide rail, and the rotating shaft forms a rotating structure through a first motor.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this invention, when the second motor drives the shaft to rotate with the first gear, the first and second gears mesh, driving the two shafts to rotate, which in turn drives the two slides to expand and contract synchronously. The two slides can form a circle, which can surround the bridge pier and quickly connect and install with the pier. The steel pipe and counterweight at the bottom can provide support. When the ultrasonic tester makes a circular motion, it maintains the stability of the entire device, provides a path for the ultrasonic tester, and realizes fully automatic detection.

[0018] In this invention, the rotation of the lead screw drives the circular tube to move horizontally in a straight line, which in turn drives the disc to move. The probe's data passes through the top of the support rod, which supports the height of the probe. When the disc moves horizontally, it drives the probe to move horizontally in a straight line, ensuring that the probe and the pier remain in contact. The lead screw has a self-locking function; once the lead screw stops rotating, the probe position is fixed and will not easily loosen. When the pulley rotates, it drives the entire ultrasonic tester to move in a circular motion along the slide, and the probe moves in a synchronous and stable circular motion.

[0028] The adjustment assembly 3 includes a support rod 301, a telescopic rod 302 welded to the top of the support rod 301, a disc 303 welded to the other end of the telescopic rod 302, a round tube 304 welded to the surface of the disc 303, and a lead screw 305 internally threaded to one end of the round tube 304.

[0029] Assembly component 4 includes a first gear 401, a second gear 402 meshing on one side of the first gear 401, a shaft 403 welded to the inner wall of the first gear 401 and the second gear 402, a slide rail 404 welded to the top of the shaft 403, and the output shaft of the second motor 405 mounted at the bottom of the shaft 403.

[0030] In this embodiment, as Figure 1 and Figure 5 As shown, slide rail 404 and shaft 403 are set as a group, and there are two groups in total. The cross-section of slide rail 404 is set as arc. It should be noted that the two slide rails 404 can form a circle, which can surround the bridge pier in the middle, provide the ultrasonic tester 1 with a travel route, and realize fully automatic detection.

[0031] In this embodiment, as Figure 1 and Figure 5 As shown, the shaft 403 forms a rotating structure through the second motor 405, and the bottom of the slide 404 is provided with a steel pipe and a counterweight. It should be noted that when the second motor 405 drives the shaft 403 to rotate with the first gear 401, the first gear 401 and the second gear 402 mesh to drive the two shafts 403 to rotate, which in turn drives the two slides 404 to move synchronously in an unfolding and retracting motion. The steel pipe and counterweight at the bottom can play a supporting role, and maintain the stability of the entire device when the ultrasonic tester 1 makes a circular motion.

[0032] In this embodiment, as Figure 4 As shown, a probe is inserted into the top of the ultrasonic tester 1. The outer shell of the probe is bonded to the inner wall of the disc 303. The central axis of the telescopic rod 302 is perpendicular to the central axis of the support rod 301. It should be noted that the probe's data passes through the top of the support rod 301. The support rod 301 supports the height of the probe. When the disc 303 moves horizontally, it drives the probe to move horizontally in a straight line, controlling the probe to always keep in contact with the pier.

[0033] In this embodiment, as Figure 4As shown, the top of the lead screw 305 and the support rod 301 are connected by a rotating method. It should be noted that by rotating the lead screw 305, the circular tube 304 is driven to move horizontally in a straight line, which in turn drives the disc 303 to move.

It should be noted that the back of the ultrasonic tester 1 is welded to the fixed frame 201. The first motor 203 drives the rotating shaft 202 to rotate, which in turn drives the pulley 204 to rotate. When the pulley 204 rotates, it drives the entire ultrasonic tester 1 to make a circular motion along the slide rail 404.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first align the slide rail 404 of assembly component 4 with the front of the pier, start the second motor 405, the second motor 405 drives the shaft 403 to rotate, the first gear 401 meshes with the second gear 402, the two shafts 403 begin to rotate synchronously in opposite directions, further driving the top slide rail 404 to begin to close, until the other end of the slide rail 404 is in contact, the two slide rails 404 form a circle, adjust the position between the inner wall of the slide rail 404 and the pier to keep the pier in the center, adjust the position of the probe. The lead screw 305 is rotated, and the lead screw 305 is forward-driven to bring the pier column closer to the circular tube 304. The inner rod of the telescopic rod 302 slides along the outer rod until the probe is in contact with the surface of the pier column. The ultrasonic tester 1, model CT350, is started. At the same time, the first motor 203 is started. The first motor 203 drives the rotating shaft 202 to rotate, which in turn drives the pulley 204 to rotate.
