Description

Technical Field

[0001] This utility model belongs to the field of bridge engineering technology, and in particular relates to a bridge damage diagnosis device for bridge engineering inspection. Background Technology

[0002] Ground-penetrating radar (GPR) is a non-destructive testing technology that uses high-frequency electromagnetic waves and is widely used in bridge damage detection. GPR emits high-frequency electromagnetic pulses and receives the reflected signals; analyzing these signals allows for the acquisition of information about the bridge's internal structure, such as cracks, cavities, and the distribution of reinforcing steel.

[0003] For example, Chinese patent CN217587581U discloses a retractable ground-penetrating radar traction device for radar detection, including a back plate, shoulder supports on the upper left and right sides of the back plate, and waist supports on the lower left and right sides of the back plate. The rear side of the back plate has two adjustable tracks, each connected to a traction belt via a traction belt fixing buckle. The ends of the two traction belts are connected to a Y-shaped connector, the other end of which is connected to two canvas straps for connecting radar antennas. Each canvas strap has a set of canvas strap adjustment holes. This technical solution has the advantages of easy installation and use, applicability to single or multiple shielded radar antennas, simultaneous traction of multiple frequency ground-penetrating radar antennas, carrying GPS high-precision positioning equipment for detection, and the ability to securely carry the radar equipment on the back after detection, meeting the advantages of radar detection in various locations. However, the above patent has the following problems:

[0004] Since data positioning relies on GPS, there are some shortcomings in actual work. For example, when there are dense roadside trees or many tall buildings, which seriously affect GPS signal reception, the quality of the measured data will be severely damaged, the survey line will deviate from the actual location, and even the data will show false anomalies, resulting in repeated scanning or missing scans by ground penetrating radar. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a bridge damage diagnosis device for bridge engineering inspection, achieving the effect of uniform and precise traction ground-penetrating radar movement.

[0006] In view of this, the present invention provides a bridge damage diagnosis device for bridge engineering inspection, including a frame, with steering wheels for steering at both the front and rear ends of the frame, a motor for controlling the steering angle of the steering wheels fixedly installed on the top of the frame, power wheels for walking on both sides of the frame, a ground penetrating radar fixedly installed on the top of the frame, a marking mechanism for marking fixedly installed at the center of the rear end of the frame, and detection heads for detecting the marks extending outward from both sides of the frame.

[0007] Preferably, both the steering wheel and the drive wheel are connected below the electromagnetic telescopic sleeve, and the fixed end of the electromagnetic telescopic sleeve is fixedly connected to the vehicle frame and the steering unit of the vehicle frame, respectively.

[0008] Preferably, the power wheel includes a connecting plate, a reducer is fixedly mounted on the surface of the connecting plate, a motor is fixedly mounted on the input end of the reducer, and the output end of the reducer passes through the connecting plate and is fixedly connected to a roller on the other side of the connecting plate.

[0010] Preferably, there are two plug-in ends, the extension rod is composed of two diagonally connected triangles, and two plug-in sleeves are fixedly installed below the extension rod.

[0011] Preferably, the length of the extension rod is half the width of the frame, and the two detection heads are positioned one forward and the other backward.

[0012] Preferably, the drawing mechanism includes a sleeve, the inside of which is filled with white lime slurry, and the bottom end of the sleeve has three outlets. A slidable partition is provided between the sleeve and the three outlets. An electromagnet is provided in the middle of the outlets on both sides, and a connecting plate is slidably connected inside the outlets on both sides. The electromagnet periodically pushes the connecting plate to open and close the outlets on both sides.

[0013] Preferably, a power source is provided at the top of the sleeve, and the output end of the power source is located inside the sleeve and a blade is fixedly installed thereon.

[0014] The beneficial effects of this utility model are:

[0015] 1. This bridge damage diagnosis equipment for bridge engineering inspection controls the movement of the vehicle frame along the edge.

Three outlets are located at the bottom of the sleeve, and a sliding partition is installed between the sleeve and the three outlets. An electromagnet is installed in the middle of one of the two outlets, and a connecting plate is slidably connected inside the two outlets.

[0024] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0025] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0026] This application discloses a bridge damage diagnosis device for bridge engineering inspection, including a frame 1. Steering wheels 2 are provided at both the front and rear ends of the frame 1 for steering. A motor 3 for controlling the steering angle of the steering wheels 2 is fixedly installed on the top of the frame 1. Power wheels 4 for walking are provided on both sides of the frame 1. Ground penetrating radar 5 is fixedly installed on the top of the frame 1. A marking mechanism 6 for marking is fixedly installed at the center of the rear end of the frame 1. Detection heads 7 for detecting marks extend outward from both sides of the frame 1.

[0027] In one embodiment, both the steering wheel 2 and the power wheel 4 are connected to the lower part of the electromagnetic telescopic sleeve 8. The fixed end of the electromagnetic telescopic sleeve 8 is fixedly connected to the frame 1 and the steering unit of the frame 1, respectively. The electromagnetic sleeve 601, which is set separately, can make one side of the steering wheel 2 and the power wheel 4 rise and fall. If the detection position is half above the step and half below the step, the electromagnetic sleeve 601 is raised and lowered to keep the ground penetrating radar 5 horizontal.

[0028] In one embodiment, the power wheel 4 includes a connecting plate 9, a reducer 10 is fixedly mounted on the surface of the connecting plate 9, a motor 11 is fixedly mounted on the input end of the reducer 10, and the output end of the reducer 10 passes through the connecting plate 9 and is fixedly connected to a roller 12 on the other side of the connecting plate 9. This arrangement can provide power so that the device can move.

[0029] Specifically, the detection head 7 includes a plug-in end 701 located above the frame 1, a plug-in sleeve 703 inserted above the plug-in end 701, an extension rod 704 fixedly installed above the plug-in sleeve 703, and a sensor 702 fixedly installed at the end of the extension rod 704 away from the plug-in sleeve 703. With this configuration, the trajectory drawn by the drawing mechanism 6 can be detected.

[0030] In one embodiment, there are two plug-in ends 701, and the extension rod 704 is composed of two diagonally connected triangles. Two plug-in sleeves 703 are fixedly installed below the extension rod 704. This arrangement can ensure the strength of the detection head 7.

[0031] In one embodiment, the length of the extension rod 704 is half the width of the frame 1, and the two detection heads 7 are positioned so that the trajectory of the frame 1 can be detected by the detection heads 7 when it moves forward or backward.

[0032] Specifically, the drawing mechanism 6 includes a sleeve 601, the inside of which is filled with white lime slurry. At this time, the detection head 7 is a visual recognition detection unit. The bottom end of the sleeve 601 is provided with three outlets 602. A sliding partition 603 is provided between the sleeve 601 and the three outlets 602. An electromagnet 604 is provided in the middle of the outlets 602 on both sides. A connecting plate 605 is slidably connected inside the outlets 602 on both sides. Alternatively, a device that reciprocates the connecting plate 605 with an equal solid line can be used instead. The electromagnet 604 periodically pushes the connecting plate 605 to open and close the outlets 602 on both sides. With this setting, two dashed lines and one solid line can be formed during the movement for detection. This setting has obvious features and is easy to remove later.

[0033] In one embodiment, a power source 606 is provided at the top of the sleeve 601, and a blade 607 is fixedly installed inside the sleeve 601 at the output end of the power source 606. This arrangement can prevent the lime slurry from settling.

[0034] In this embodiment, the bridge damage diagnosis equipment for bridge engineering inspection uses a control vehicle 1 to move along the edge. During the movement, the drawing mechanism 6 draws guide lines. After the vehicle 1 moves laterally by a width, the detection head 7 detects the guide lines drawn by the drawing mechanism 6 and controls the motor 3 to adjust the angle, so that the vehicle 1 moves again parallel to the upper side of the vehicle 1's movement trajectory. Repeating this action allows for radar scanning of the entire bridge.
