Abstract

The invention discloses a mobile bracket and method for detecting damage of an underwater part of a pier. The mobile bracket comprises metal hoses, a sliding sleeve, a stretching device and a robot seat. A plurality of metal hoses form a hoop surrounding the pier, the sliding sleeve sleeves the hoop, and the stretching device is connected between the sliding sleeve and the robot seat. The method comprises the following steps: sleeving the metal hoop with the sliding sleeve to determine a horizontal coordinate of the damaged part; and stretching a rhombic stretching rack and a tape in the stretching device jointly up and down to determine a vertical coordinate of the damaged part. According to the mobile bracket and method, the two-dimensional coordinates of the damaged part of an underwater damaged part of a bridge can be accurately positioned, the problems that a robot in the current stage is washed away or lost due to rapid flow and the like are solved, the detecting efficiency and quality of underwater hidden danger part of the bridge are improved, and the detection cost is effectively lowered.

Description

technical field

[0001] The invention relates to a detection device and method for damage to underwater parts of bridge piers, and belongs to the field of structure detection devices. Background technique

[0002] Concrete bridge piers will have cracks during work, and will also be damaged by water erosion, corrosion, ship impact, earthquakes, etc. The damage detection of underwater parts of bridge piers is easy to become a blind spot of detection. At present, the detection of the underwater part of bridge piers in China is mainly carried out manually by divers wearing underwater photography equipment. This detection method is inefficient and it is difficult to locate the specific coordinates of cracks. Based on the above situation, it is an urgent technical problem to design a movable support for damage detection of the underwater part of the pier, which can be used to locate the specific location of the damage more accurately, improve the detection efficiency, and replace ...
