DETAILED DESCRIPTION

[0020] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0021] A concrete crack detection device for safe engineering construction, such as Figure 1-Figure 6As shown, it includes a support frame 1, an electric guide rail 2, a slide rail 3, a vernier caliper 4, a guide seat 5, a fixed block 16, a U-shaped rod 6, a first elastic member 7, a guide block 17 and a second elastic member 18. An electric guide rail 2 is arranged between the support frames 1, and a slide rail 3 is arranged on the movable part of the electric guide rail 2. A guide block 17 is slidably connected to the slide rail 3, and a vernier caliper 4 is slidably connected to the guide block 17. The vernier caliper 4 is a vernier caliper 4 with a digital display. A rectangular hole is opened at the bottom of the vernier caliper 4, and a second elastic member 18 is connected between the inner wall of the top of the rectangular hole and the guide block 17. A guide seat 5 is arranged on the left side of the outer measuring claw below the vernier caliper 4, and a fixed block 16 is arranged on the left side of the outer measuring claw above. The upper end of the U-shaped rod 6 is arranged at the bottom of the fixed block 16, and the U-shaped rod 6 slides through the guide seat 5. A first elastic member 7 is arranged on the outer side of the U-shaped rod 6, and the first elastic member 7 is located between the guide seat 5 and the fixed block 16.

[0022] like Figure 2 and Figure 3 As shown, it also includes a connecting rod 8 and an inclined downward pressing rod 9. The connecting rod 8 is provided at the lower end of the U-shaped rod 6, and the inclined downward pressing rod 9 is provided on the left side of the top of the electric guide rail 2.

[0023] like Figure 5 As shown, it also includes a mounting plate 10 and a CCD camera 11. The mounting plate 10 is provided on the left side of the top of the electric guide rail 2. The mounting plate 10 is located on the left side of the inclined pressure rod 9. The CCD camera 11 is provided on the right side of the mounting plate 10. The CCD camera 11 can record the data on the digital display vernier caliper 4 and record and save it by taking pictures.

[0024] like Figure 4 As shown, it also includes a cylinder 12 and a connecting piece 13 . The cylinder 12 is arranged on the right side of the slide rail 3 , and the cylinder 12 is connected to the vernier caliper 4 through the connecting piece 13 .

[0025] like Figure 3 As shown, an ultrasonic sensor 15 is also included. The ultrasonic sensor 15 is provided on the side of the measuring claw in the vernier caliper 4 close to the electric guide rail 2. The ultrasonic sensor 15 can detect the internal structure of the crack and provide data support for evaluating the crack depth and internal conditions.

[0026] like Figure 6 As shown, a suction cup 14 is also included. The suction cup 14 is provided on the rear side of the support frame 1.

[0027] The staff first uses the suction cup 14 to install the support frame 1 at the position of the concrete crack that needs to be detected, and then adjusts the vernier caliper 4 to the leftmost starting point of the electric guide rail 2. After starting the cylinder 12, the cylinder 12 pushes the connecting piece 13 to move the vernier caliper 4 along the slide rail 3 toward the crack direction. In this process, the connecting rod 8 gradually approaches and finally contacts the inclined downward rod 9. The inclined surface structure of the inclined downward rod 9 will squeeze the connecting rod 8, and then pull the upper outer measuring claw downward through the U-shaped rod 6, so that the upper and lower inner measuring claws gradually approach until they are closed. At this time, the first elastic member 7 and the second elastic member 18 are both in a compressed state; when the vernier caliper 4 moves until its inner measuring claw accurately enters the crack, the cylinder 12 is closed, and then the electric guide rail 2 is started, and the electric The moving guide rail 2 drives the vernier caliper 4 to move from left to right. Once the connecting rod 8 is separated from the inclined downward pressure rod 9, under the action of the restoring force of the first elastic member 7, the upper inner measuring claw begins to move slowly upward until it contacts the upper surface inside the crack. At the same time, the second elastic member 18 will expand and contract according to the actual shape of the bottom of the crack; so that the inner measuring claw always maintains good contact with the bottom of the crack. During the entire lateral movement of the vernier caliper 4, the first elastic member 7 and the second elastic member 18 ensure that the inner measuring claw always fits tightly to the upper and lower sides of the crack, thereby ensuring the accuracy of the measurement; at the same time, the CCD camera 11 on the mounting plate 10 can be turned on. The camera can record the data of the vernier caliper 4 in real time and save detailed image data by taking pictures for subsequent analysis. This design not only improves the detection efficiency, but also ensures the accuracy and integrity of data recording.
