[0002] Bridges play a vital role in crossing mountains and rivers. Every time a bridge is built, it relies on the hard work of builders and the progress and innovation of bridge-building technology. However, the piers at the bottom of the bridge are the foundation of the bridge. Because the piers will produce fatigue under long-term loads, affecting the durability of the pier structure, the piers need to be inspected regularly.

This operation is a high-altitude work, which results in slow inspection speed and certain danger. Therefore, an automatic detection device for cracks in construction engineering structures is proposed to solve the above problems. Utility Model Content

[0026] The lock core assembly 5 includes a wedge head pull rod 501, a baffle 502 and a first spring 503. The right end of the second arc arm 3 is slidably connected to the wedge head pull rod 501 extending into the latch pin 4.

The right side of the baffle 502 is fixedly connected to the first spring 503 located outside the wedge head pull rod 501 and fixedly connected to the second arc arm 3.

[0027] Pull the wedge head pull rod 501, and at the same time, the first spring 503 undergoes elastic deformation, so that the wedge head pull rod 501 is separated from the latch pin 4, so that the first arc arm 1 can rotate around the hinge between it and the second arc arm 3, and the latch pin 4 is inserted into the second arc arm 3. During this process, the latch pin 4 first contacts the wedge head pull rod 501, and then pushes the wedge head pull rod 501 out, and at the same time, the first spring 503 undergoes elastic deformation. When the latch pin 4 enters to a certain depth, the first spring 503 recovers its elastic deformation, so that the wedge head pull rod 501 enters the latch pin 4, and the first arc arm 1 and the second arc arm 3 are fixedly connected;

[0028] The auxiliary wheel assembly 7 includes a Y-shaped bracket 701, a second spring 702 and a second double wheel axle 703.

[0029] The adjustment assembly 8 includes a threaded rod 801, a mounting bracket 802 and a sliding rod 803. The bottom of the first arc arm 1 is threadedly connected to the threaded rod 801 extending above it, and the top of the threaded rod 801 is rotatably connected to the mounting bracket 802. The bottom of the mounting bracket 802 is fixedly connected to the sliding rod 803 which is symmetrically distributed left and right and slidably connected to the first arc arm 1. The inside of the mounting bracket 802 is rotatably connected to the first double wheel axle 9 which is symmetrically distributed front and back and extends to the left side thereof. The angle between the threaded rod 801 and the adjacent Y-shaped bracket 701 is 120°, and the top of the mounting bracket 802 is provided with a crack detector 2;

[0030] When the threaded rod 801 is rotated, the force generated by the rotation of the thread drives the mounting frame 802 to move toward the column bridge pier 6, and at the same time, the sliding rod 803 slides with the first arc arm 1. When the first double wheel axle 9 contacts the column bridge pier 6, the Y-shaped bracket 701 slides upward, the second spring 702 undergoes elastic deformation, and the second double wheel axle 703 contacts the column bridge pier 6 until the mounting frame 802 drives the crack detector 2 to move to a distance where crack detection can be performed on the column bridge pier 6;

[0032] Start the servo motor 111, which drives the second pulley 112 to rotate, and then drives the first pulley 10 to rotate synchronously through the transmission belt 113, so that the device can move upward along the outer wall of the columnar pier 6, and the crack detector 2 can detect cracks on the columnar pier 6.

[0033] Working principle:

[0034] Step 1: By pulling the wedge rod 501, the first spring 503 is elastically deformed, so that the wedge rod 501 is separated from the latch 4, so that the first arc arm 1 can rotate around the hinge with the second arc arm 3, and the device is placed outside the column bridge pier 6, so that the first arc arm 1 and the second arc arm 3 hold the column bridge pier 6, and the blocking latch 4 is inserted into the second arc arm 3. During this process, the latch 4 first contacts the wedge rod 501, and then pushes the wedge rod 501 out, and the first spring 503 is elastically deformed. When the latch 4 enters to a certain depth, the first spring 503 restores the elastic deformation, so that the wedge rod 501 enters the latch 4, and the first arc arm 1 and the second arc arm 3 are fixedly connected;

[0035] Step 2: Rotate the threaded rod 801. The force generated by the rotation of the thread drives the mounting frame 802 to move toward the column bridge pier 6. At the same time, the sliding rod 803 slides with the first arc arm 1. When the first double wheel axle 9 contacts the column bridge pier 6, the Y-shaped bracket 701 slides upward, the second spring 702 undergoes elastic deformation, and the second double wheel axle 703 contacts the column bridge pier 6 until the mounting frame 802 drives the crack detector 2 to move to a distance where crack detection can be performed on the column bridge pier 6.

[0036] Step 3: Start the servo motor 111, which drives the second pulley 112 to rotate, and then drives the first pulley 10 to rotate synchronously through the transmission belt 113, so that the device can move upward along the outer wall of the columnar pier 6, and the crack detector 2 can detect cracks on the columnar pier 6.
