Description

Technical Field

[0001] This utility model relates to the technical field of wall inspection equipment, specifically a radar probe angle locking mechanism for detecting wall tie bars. Background Technology

[0002] In the field of building construction quality inspection, the installation quality of wall tie bars directly affects the overall stability and seismic performance of the wall. Therefore, accurate inspection of wall tie bars is one of the key aspects of building construction quality control. Currently, the industry commonly uses radar instruments to inspect wall tie bars. The electromagnetic waves emitted by the radar probe penetrate the wall, and the location, quantity, and distribution of the tie bars are analyzed based on the reflected signals. In actual testing, to ensure the accuracy of the test data, the detection angle of the radar probe needs to be flexibly adjusted according to the actual structure of the wall and the testing requirements.

[0003] However, the existing radar probe angle locking mechanism for wall tie bar detection still has some shortcomings in actual use: most mechanisms can only achieve angle adjustment in a single dimension, and the adjustment accuracy is low, making it difficult to meet the accurate detection needs under different wall structures; some mechanisms with multi-angle adjustment functions have complex adjustment structures, are cumbersome to operate, and have poor stability after angle locking, making it easy for the detection data to deviate due to slight probe displacement during the detection process.

[0004] To address this issue, we designed a radar probe angle locking mechanism for detecting wall tie bars. Utility Model Content

[0005] The purpose of this utility model is to provide a radar probe angle locking mechanism for detecting wall tie bars, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a radar probe angle locking mechanism for detecting wall tie bars, including a mounting base and a radar probe body. A mounting plate is provided at the top of the mounting base, and an adjustment component is provided on the mounting base. The mounting plate is rotatably mounted on the top of the mounting base through the adjustment component. A fine-tuning component for adjusting the angle of the radar probe body is provided between the radar probe body and the mounting plate.

[0007] Furthermore, the fine-tuning component includes an adjustment platform fixedly mounted on the upper surface of the mounting plate, a rotating seat rotatably connected to the top of the adjustment platform, and the radar probe body fixedly mounted on the upper surface of the rotating seat; rotating shafts are fixedly connected to both ends of the rotating seat, the ends of the rotating shafts are mounted in bearing seats, and the bearing seats are fixedly connected to the adjustment platform.

[0008] Furthermore, a sprocket is mounted on the shaft on one side of the rotating seat, and the sprocket is connected to the servo motor via a chain; the servo motor is installed inside the adjustment platform.

[0009] Furthermore, the adjustment assembly includes a connecting plate fixedly installed on the bottom surface of the mounting plate. The connecting plate is rotatably installed on the side wall of the mounting base. The mounting plate is rotatably connected to the mounting base through the connecting plate. A movable rod is fixedly installed on the side wall of the connecting plate near the mounting base. A sliding groove for the movable rod to move is opened through the mounting base. The sliding groove is semi-circular in shape. The movable rod is slidably installed in the sliding groove and is slidably connected to the inner side wall of the sliding groove. A fastening nut for tightening against the mounting base is threaded to the end of the movable rod away from the connecting plate.

[0010] Furthermore, a cable is electrically connected to the radar probe body, and the end of the cable away from the radar probe body is connected to an external power source.

[0011] Furthermore, the mounting plate has multiple heat dissipation holes extending through it.

[0012] Furthermore, it also includes a controller, which is communicatively connected to the servo motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by coordinating the adjustment component and the fine-tuning component, the radar probe body achieves a dual angle adjustment function of "large-range coarse adjustment + small-amplitude fine adjustment". The adjustment dimensions are rich and can meet the precise angle adjustment under different wall structures and detection needs, solving the problems of low adjustment accuracy and single dimension of existing mechanisms.

[0015] 2. This utility model achieves a wide range of angle adjustment of the radar probe body through the adjustment component. By utilizing the rotation of the connecting plate and the guidance of the semi-circular slide groove, and in conjunction with the locking of the fastening nut, the coarse angle adjustment is fixed.

[0016] 3. In this invention, when a small-amplitude, precise angle adjustment of the radar probe body is required, the controller controls the servo motor to rotate forward or backward by a certain angle. The servo motor drives the rotating shaft and the rotating base to rotate by a certain angle via a chain. Since the radar probe body is fixed on the rotating base, the deflection of the rotating base causes the radar probe body to achieve a small-amplitude angle adjustment. After adjusting to the precise detection angle, the servo motor stops running, thereby locking the fine-tuning angle of the radar probe body. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a radar probe angle locking mechanism for detecting wall tie bars, including a mounting base 1 and a radar probe body 3. A mounting plate 2 is provided at the top of the mounting base 1, and an adjustment component 4 is provided on the mounting base 1. The mounting plate 2 is rotatably mounted on the top of the mounting base 1 through the adjustment component 4. A fine-tuning component 5 for adjusting the angle of the radar probe body 3 is provided between the radar probe body 3 and the mounting plate 2. A cable 8 is electrically connected to the radar probe body 3, and the end of the cable 8 away from the radar probe body 3 is connected to an external power source.

[0024] The adjustment assembly 4 includes a connecting plate 13 fixedly installed on the bottom surface of the mounting plate 2. The connecting plate 13 is rotatably installed on the side wall of the mounting base 1. The mounting plate 2 is rotatably connected to the mounting base 1 through the connecting plate 13. A moving rod 14 is fixedly installed on the side wall of the connecting plate 13 near the mounting base 1. A sliding groove 15 for the moving rod 14 to move is opened through the mounting base 1. The sliding groove 15 is semi-circular in shape. The moving rod 14 is slidably installed in the sliding groove 15. The moving rod 14 is slidably connected to the inner side wall of the sliding groove 15. A fastening nut 16 for tightening against the mounting base 1 is threaded to the end of the moving rod 14 away from the connecting plate 13.

[0025] In practice, the mounting base 1 is first fixed in the designated position of the detection equipment. The radar probe body 3 is connected to the external power supply via cable 8 to ensure that the probe can work normally after being powered on. When a large-range angle adjustment of the radar probe body 3 is required, the fastening nut 16 in the adjustment assembly 4 is loosened, and the mounting plate 2 is pushed. The mounting plate 2 drives the connecting plate 13 on the bottom surface to rotate around the side wall of the mounting base 1. At this time, the moving rod 14 on the connecting plate 13 slides along the semi-circular sliding groove 15 on the mounting base 1. After the radar probe body 3 is rotated to the approximate target angle, the fastening nut 16 is tightened. The fastening nut 16 presses against the outer side wall of the mounting base 1, and the position of the moving rod 14 is fixed by friction, thereby locking the angle of the mounting plate 2 and the radar probe body 3, and completing the large-range angle adjustment.

[0026] See Figure 3 and Figure 4 The fine-tuning component 5 includes an adjustment platform 6 fixedly mounted on the upper surface of the mounting plate 2. A rotating seat 7 is rotatably connected to the top of the adjustment platform 6, and the radar probe body 3 is fixedly mounted on the upper surface of the rotating seat 7. Rotating shafts 12 are fixedly connected to both ends of the rotating seat 7, and the ends of the rotating shafts 12 are installed in bearing seats, which are fixedly connected to the adjustment platform 6. A sprocket 11 is mounted on the rotating shaft 12 on one side of the rotating seat 7, and the sprocket 11 is connected to the servo motor 10 via a chain 9. The servo motor 10 is installed inside the adjustment platform 6.

[0027] In practice, when a small-amplitude, precise angle adjustment of the radar probe body 3 is required, the servo motor 10 is controlled to rotate forward or backward by a certain angle by the controller. The servo motor 10 drives the rotating shaft 12 and the rotating seat 7 to rotate by a certain angle through the chain 9. The radar probe body 3 is fixed on the rotating seat 7. Therefore, the deflection of the rotating seat 7 drives the radar probe body 3 to achieve a small-amplitude angle adjustment. After the precise detection angle is adjusted, the servo motor 10 stops running, thereby locking the adjustment angle of the radar probe body 3.

[0028] See Figure 2 Multiple heat dissipation holes 17 are provided through the mounting plate 2. During the operation of the radar probe body 3, the heat generated by the probe can be quickly dissipated to the external environment, thus preventing the internal temperature of the probe from becoming too high.

[0029] Working principle:

[0030] This invention achieves a wide range of angle adjustment for the radar probe body 3 through the adjustment component 4. The coarse angle adjustment is fixed by the rotation of the connecting plate 13 and the guidance of the semi-circular slide groove 15, combined with the locking of the fastening nut 16. The controller controls the servo motor 10 to rotate forward or backward by a certain angle. The servo motor 10 drives the rotating shaft 12 and the rotating seat 7 to rotate by a certain angle via the chain 9. Since the radar probe body 3 is fixed on the rotating seat 7, the deflection of the rotating seat 7 causes the radar probe body 3 to achieve a small-amplitude angle adjustment. After the servo motor 10 stops, the fine angle adjustment is locked. Simultaneously, the heat dissipation holes 17 on the mounting plate 2 facilitate heat dissipation during probe operation, and the cable 8 ensures a stable power supply to the probe. The overall design, through a dual adjustment mode of "coarse adjustment + fine adjustment" and a dual locking structure, solves the problems of low adjustment accuracy and poor stability in existing mechanisms, improving the efficiency and data accuracy of wall tie bar detection.
