[0021] 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.

[0022] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a corrosion resistance testing device for municipal bridges, including a testing body 1 for testing municipal bridges;

[0023] An adjustment component for adjusting the detection position of the detection body 1 in the horizontal direction is installed on the outside of the detection body 1.

[0024] The bottom of the detection body 1 is equipped with a control component for adjusting the detection body 1 in the vertical direction;

[0025] The adjustment assembly includes a fixed frame 2 located at the bottom of the detection body 1. The fixed frame 2 has an inner cavity 21. An outer plate 23 is fixedly connected to the right end of the outer wall of the fixed frame 2. Movable blocks 22 are fixedly connected to the front and rear sides of the outer wall of the detection body 1. A motor 24 is fixedly installed on the front top of the outer plate 23. A threaded rod 25 is fixedly connected to the output end of the motor 24. The end of the threaded rod 25 is rotatably connected to the right side of the inner wall of the fixed frame 2. The threaded rod 25 and the movable block 22 are threadedly connected.

[0026] Through the above technical solution, the device consists of an adjustment component and a control component. The two components work together to adjust the detection position of the detection body 1. At the same time, the fixed frame 2 needs to have a certain length to ensure that the detection body 1 has enough space to slide in the inner cavity 21. The motor 24 is installed on the top of the outer plate 23 and drives the threaded rod 25 to rotate. Thus, through the threaded transmission between the threaded rod 25 and the moving block 22, the detection body 1 is moved along the outer surface of the threaded rod 25, realizing detection operations at different positions in the same horizontal direction and avoiding the randomness of the detection results.

[0027] Please see Figure 1 and Figure 2 The control component includes a mounting base 3 located at the bottom of the fixed frame 2. Cylinders 31 are fixedly mounted on both sides of the top wall of the mounting base 3. The output end of the cylinders 31 is fixedly connected to the bottom wall of the fixed frame 2. Fixed columns 32 are fixedly connected to the four corners of the top wall of the mounting base 3. A movable column 33 is slidably connected to the top of the fixed column 32. The top end of the movable column 33 is fixedly connected to the bottom wall of the fixed frame 2.

[0028] The bottom of the mounting base 3 is fixedly connected to the base 4, and the front sides of the outer wall of the base 4 are fixedly connected to the fixed drill bits 5 for inserting into the outer wall of the bridge.

[0029] Through the above technical solution, two cylinders 31 are installed on the top of the mounting base 3. The cylinders 31 provide power input to the control component and adjust the movement of the detection component in the vertical direction. At the same time, the moving column 33 moves with the fixed frame 2, and works with the cylinders 31 to move the fixed frame 2. Meanwhile, the fixed column 32 and the moving column 33 also provide support for the detection body 1 and the adjustment component. When the bridge type and detection position are suitable, the mounting base 3 is inserted into the bridge through the fixed drill bit 5 to quickly fix the device, thereby facilitating the detection operation by the staff.

[0030] Please see Figure 1 , Figure 2 and Figure 3 The outer wall of the fixed drill bit 5 is fixedly connected to the mounting plate 6, and the outer surface of the mounting plate 6 is provided with positioning holes 7 arranged in a ring array with the central axis of the mounting plate 6 as the axis.

[0031] A guide rod 8 is fixedly connected to the rear side of the inner wall of the fixed frame 2, and the guide rod 8 passes through the rear movable block 22;

[0032] The control panel 9 is fixedly installed on the right side of the outer wall of the base 4. The control panel 9 is electrically connected to the motor 24 and the cylinder 31 respectively.

[0033] Through the above technical solution, the mounting plate 6 is fixed on the outside of the fixed drill bit 5. By opening positioning holes 7 on the outer surface of the mounting plate 6, when it is not suitable to insert the fixed drill bit 5 into the bridge, the device can be fixed by bolts and positioning holes 7. The guide rod 8 is used in conjunction with the threaded rod 25. When the detection body 1 moves in the horizontal direction, the guide rod 8 ensures the uniqueness of the movement direction of the detection body 1. The surface of the device body is equipped with a control panel 9 for controlling the motor 24 and the cylinder 31, which is convenient for personnel to control. At the same time, the device can also be controlled at the center of the ground by a signal to ensure the stability of the device operation.

[0034] Working Principle: First, the installation method is determined based on the bridge location to be inspected. When the location and materials are suitable, the fixed drill bit 5 on the front side of the base 4 is directly inserted into the bridge body. When it is inconvenient to directly fix it with the fixed drill bit 5, the entire device can be fixed using bolts and positioning holes 7. The two fixing methods depend on the specific situation. Then, the inspection operation is performed through the inspection body 1. At the same time, the bottom of the inspection body 1 is equipped with a long fixing frame 2. After the inspection body 1 has completed the inspection at a certain position, the motor 24 is started through the control panel 9. The motor 24 drives the threaded rod 25 to rotate. During the rotation of the threaded rod 25, the front moving block 22 moves horizontally along the outer surface of the threaded rod 25. Since the moving blocks 22 on both sides are fixedly connected to the inspection body 1, the movement of the front moving block 22 will drive the inspection body 1 to move synchronously. At the same time, in the inner cavity 2... A guide rod 8 is provided on the rear side of the detection body 1. The guide rod 8 is in a fixed state, and the moving block 22 on the rear side slides along the guide rod 8 to follow the detection body 1, thereby ensuring the stability of the movement direction of the detection body 1. By performing detection operations at multiple positions in the same horizontal direction, the accuracy of the detection results is ensured. At the same time, the cylinder 31 can be activated to control the fixed frame 2 to move in the vertical direction, thereby controlling and adjusting the detection body 1 to perform detection operations at different heights. Meanwhile, when the fixed frame 2 moves up and down, the moving column 33 slides inside the fixed column 32 along with the fixed frame 2, thereby cooperating with the cylinder 31 to provide auxiliary support for the detection body 1 and the adjustment components, ensuring the normal operation of the device. By cooperating with the adjustment components and the control components, the device can perform detection operations at different positions, improving the practicality and ease of use of the device.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
