Embodiment 1

[0035] Such as Figure 1 to Figure 5 As shown, a variable-section pier underwater structure detection device includes a top fixing mechanism 1, a clamping and pushing mechanism 2, an X-shaped self-adaptive detection mechanism 3 and a fixing bracket 4; the top fixing mechanism 1 is arranged on the fixing bracket 4, and is connected to the X-type adaptive detection mechanism 3 through the hanging module 101, and one end of the X-type adaptive detection mechanism 3 is connected to the middle part of the fixed bracket 4 through the clamping and pushing mechanism 2 The top fixing mechanism 1 has a pair of rotating fixed clamps 102 for surrounding and clamping the bridge pier; the X-shaped self-adaptive detection mechanism 3 is used for sliding on the bridge pier and detecting the bridge pier.

[0036] The top fixing mechanism 1 can embrace the pier through the rotating fixed clamp 102 on the water, and the X-type adaptive detection mechanism 3 is controlled by the lifting module 10...

Embodiment 2

[0048] A detection method with the underwater structure detection device of the variable cross-section bridge pier described in Embodiment 1, the detection method is as follows: first, the detection device is carried by the fixed bracket 4, and installed on the ship used, the The top fixing mechanism 1, the clamping and pushing mechanism 2 and the X-type self-adaptive detection mechanism 3 are all connected; the ship drives to a certain distance near the pier, and the staff on board controls the rotation and fixing through the drive control module 103 The clamp 102 rotates, and the rotating fixed clamp 102 clings to the surface of the pier, and since then, the upper fixing process ends;

[0049] Subsequently, the staff controls the lifting module 101, lowers the sling 104 until the X-type detection carrying frame 301 of the X-type self-adaptive detection mechanism 3 relaxes and reserves the remaining length; the clamping and pushing mechanism 2 will Clamp the X-shaped self-ada...

Abstract

The invention discloses a variable cross-section bridge pier underwater structure detection device and a detection method thereof. The detection device comprises a top fixing mechanism, a clamping and pushing mechanism, an X-type self-adaptive detection mechanism and a fixing support, wherein the fixing mechanism surrounds a bridge pier on water through a rotatable fixing clamp; the distance between the relative positions of the detection device and the bridge pier is controlled, meanwhile, it is guaranteed that the whole device cannot shake due to water flow impact, the urgent turbulent water flow influence under major bridge detection is overcome, and the clamping and pushing mechanism clamps and pushes the X-type self-adaptive detection mechanism to wrap the bridge pier and then loosens the clamping hand. The X-type self-adaptive detection mechanism can be self-adjusted along with downward sliding to increase the opening so as to adapt to the change of the variable-cross-section bridge pier, the X-shaped self-adaptive detection mechanism moves downwards layer by layer for detection, after detection is completed, the detection mechanism is pulled back through the lifting module, the clamping and pushing device clamps and withdraws again, and the upper fixing mechanism is unlocked to complete recovery.

Description

technical field [0001] The invention relates to the technical field of underwater detection, in particular to a detection device and a detection method for underwater structures of bridge piers with variable cross-sections. Background technique [0002] In the past ten years, driven by the rapid development of the country's economy, the number of bridges in China has increased by more than 30,000 per year. At present, the total number of bridges in the country has reached 1 million. With such a huge number of bridges, a large number of bridges are aging, especially the underwater structure of bridges is eroded by running water, which has become a hidden danger that threatens the safety of bridge traffic. The detection methods of the underwater structure of bridges are different from those of the above-water structures, and there are technical difficulties such as difficult coverage of the detection range, difficulty in decentralizing detection equipment, and difficulty in ev...
