[0017] This utility model provides a device for testing the main structure of civil engineering.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a detection spindle 1, one end of which is fixedly connected to a powerful suction cup 7. The detection spindle 1 serves to connect the measuring stationary plate 2 and the measuring rotating plate 3, and can provide limit and support for the rotation of the measuring rotating plate 3, facilitating the use of the device. The powerful suction cup 7 can be adsorbed onto the surface of the measuring body, providing convenience for the use of the device. The structural structures of each component shown in the accompanying drawings of this application are all exemplary illustrations. Their specific real-time methods should be combined with the functional requirements, assembly conditions and process limitations in the actual application scenario, and the structural parameters, size specifications and connection methods should be adaptively adjusted and optimized.

[0019] Please see Figure 1 and Figure 2 A measuring plate 2 is fixedly connected to the outer surface of the main shaft 1. A bubble level 11 is fixedly installed inside the measuring plate 2. The bubble level 11 is used to measure the horizontality or verticality of the main body. The measuring plate 2 is a fixed end. During use, it is first attached to the detection position of the main structure of the civil engineering project, and then the measuring plate 3 is rotated to measure the angle of the main body. During the recording process, the angle of the detection device is kept fixed, which is convenient for the staff to record the detection data. The bubble level 11 can use the position change of the bubble inside the glass tube to indicate the tilt of the object, which makes it easy for the staff to clearly grasp the horizontal or vertical angle during the detection process, which helps to improve the accuracy of the detection.

[0020] The outer surface of the main shaft 1 is rotatably connected to a measuring plate 3, and the outer surface of the measuring plate 3 is fixedly connected to an angle pointer 5. The other end of the main shaft 1 is fixedly connected to an angle meter 8. When the staff is checking the angle of the main structure of the building, they first align the measuring plate 2 with the edge line of the main structure, and then rotate the measuring plate 3 to the other edge line of the main structure. At this time, the angle pointer 5 will rotate with the rotation of the measuring plate 3. The end of the angle pointer 5 will point to different positions in the angle meter 8 according to the angle of rotation of the angle pointer 5, so that the staff can intuitively understand the angle of the main structure of the civil engineering.

[0021] The outer surface of the measuring plate 3 is provided with a set of scale lines 6. The measuring plate 2 and the measuring plate 3 are both slidably connected to the interior of the measuring plate 9. The outer surfaces of the measuring plate 2, the measuring plate 3 and the measuring plate 9 are all fixedly installed with strong magnets 10. The scale lines 6 make it convenient for staff to directly use this device to measure the height, width and other data of the building body, thereby increasing the detection range of the device. When encountering some long bodies, the staff can pull the extending plate 9 out of the measuring plate 2 or the measuring plate 3 by stretching it to increase the measurement distance of the device and expand the detection range of the device. The strong magnets 10 have strong magnetism between them, which can fix the extending plate 9 inside the measuring plate 2 or the measuring plate 3 when not in use, preventing the extending plate 9 from sliding out on its own and affecting the portability or applicability of the device.

[0022] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The detection spindle 1 is equipped with a locking mechanism 4. The locking mechanism 4 includes a transmission slide rod 401 that slides inside the detection spindle 1. The locking mechanism 4 can lock or unlock the measuring plate 3 as needed, so that the measuring plate 3 can rotate freely during measurement and remain locked after shaping, thereby fixing the detection angle of the device. This avoids the labor intensity of the operator continuously supporting the two measuring plates with both hands, effectively reduces the error caused by human factors, and improves the detection accuracy of the device.

[0023] Please see Figure 3 and Figure 4A limiting locking block 402 is fixedly connected to the outer surface of the transmission slide rod 401. A sliding groove 406 is provided inside the detection spindle 1. The limiting locking block 402 slides inside the sliding groove 406. The surface of the limiting locking block 402 has multiple protruding baffles. The distance between the baffles and the teeth of the locking gear 403 is matched. When the limiting locking block 402 is inserted into the locking gear 403, it can mesh with the locking gear 403, thereby blocking the rotation of the locking gear 403 and locking the measuring plate 3. This keeps the misalignment angle between the measuring plate 3 and the measuring stationary plate 2 fixed. The sliding groove 406 facilitates the sliding of the limiting locking block 402 inside the detection spindle 1 and also limits the limiting locking block 402 to prevent it from rotating, thus improving the stability of locking the measuring plate 3.

[0024] A locking gear 403 is fixedly connected to the end of the measuring plate 3. A rotating groove 405 is opened on the outer surface of the detection spindle 1. The locking gear 403 rotates inside the rotating groove 405. The limiting locking block 402 is adapted to the locking gear 403. When the operator wants to fix the measuring plate 3, he presses the transmission slide rod 401 with force. The transmission slide rod 401 is compressed by the force and the return spring 404 is compressed, which drives the limiting locking block 402 to slide inside the sliding groove 406. After the limiting locking block 402 slides to a certain position, it will disengage from the locking gear 403. At this time, the locking gear 403 will no longer be limited by the limiting locking block 402 and can slide freely in the rotating groove 405, which makes it convenient for the operator to rotate the measuring plate 3 to a certain angle to carry out the inspection work on the main structure of the building.

[0025] A set of return springs 404 are fixedly connected to the end of the transmission slide rod 401. The end of the return spring 404 away from the transmission slide rod 401 is fixedly connected to the detection spindle 1. The return springs 404 are evenly distributed at the end of the transmission slide rod 401, which can provide stable elastic potential energy for the reset of the transmission slide rod 401. After the transmission slide rod 401 loses pressure, it will reset under the action of the return springs 404, so that the limit locking block 402 will mesh with the locking gear 403 again, and complete the locking of the measuring plate 3, preventing the measuring plate 3 from rotating on its own and causing deviation in the detection results.

[0026] Working principle: During use, the operator first places the device at the location on the main structure to be inspected, then presses the transmission slide rod 401 and the detection spindle 1. The force applied to the detection spindle 1 compresses the powerful suction cup 7, causing it to adhere to the surface of the building structure, providing auxiliary support for the device. Meanwhile, the force applied to the transmission slide rod 401 compresses the return spring 404, causing the limit locking block 402 to slide inside the detection spindle 1. This releases the limit locking block 402 from its limiting effect on the locking gear 403. At this point, the operator can rotate the measuring plate 3 according to the angle of the main structure. After the angle is aligned with the main body, the operator releases the transmission slide rod 401. The transmission slide rod 401 will reset under the elastic support of the return spring 404, thereby driving the limit locking block 402 to reset. This causes the limit locking block 402 to mesh with the locking gear 403 again. At this time, the locking gear 403 will be unable to rotate under the limiting action of the limit locking block 402, thus completing the locking of the measuring rotating plate 3. This keeps the angle between the measuring stationary plate 2 and the measuring rotating plate 3 stable. The operator can then intuitively understand the detection angle of the structure by using the angle pointer 5, which greatly improves the ease of use of the device.
