Bridge rectangular pier column detection system and method

Abstract

A bridge rectangular pier column detection system comprises short-edge supports arranged on two short-edge sides of a rectangular pier column and long-edge connecting rods arranged on two long-edge sides of the rectangular pier column. Wherein the tail ends of the short-side bracket and the long-side connecting rod are connected with each other so as to surround the periphery of the rectangular pier column; a movable detection device is arranged on the long-side connecting rod and is used for detecting the pier column; a climbing device is arranged on the side, close to the pier column, of the short-edge support. A clamping telescopic device is arranged at the joint of the short-side support and the long-side connecting rod so that the short-side support can clamp the pier column. An inclination sensor is arranged at the tail end of the short-side bracket to detect the horizontal state of the short-side bracket and the long-side connecting rod in the crawling process; the climbing device is provided with an adjusting module; the adjusting module is connected with the inclination sensor, receives a horizontal state signal detected by the inclination sensor, and adjusts the advancing speed of the climbing device to ensure that the climbing device always climbs in a horizontal state.

Description

technical field [0001] The invention relates to the technical field of bridge pier column detection, in particular to a bridge rectangular pier column detection system and method. Background technique [0002] In terms of appearance inspection of rectangular thin-walled pier columns of bridges: the height of rectangular thin-walled pier columns of bridges is generally above 20m, and some heights can even reach 100m or above. Non-contact measuring instruments such as distance observers have low detection efficiency and are greatly affected by the weather. They can only be observed in fine weather, with good visibility and good light. The accuracy and precision of observation and identification of appearance defects of pier columns are low, and it is impossible to identify and detect appearance defects of rectangular thin-walled pier columns at close range, and there are blind spots in appearance detection. [0003] In the detection of internal defects of bridge rectangular t...

AI Technical Summary

Problems solved by technology

The height of rectangular thin-walled pier columns of bridges is generally above 20m, and some heights can even reach 100m and above. When the height is above 3m, the ultrasonic method cannot be used to detect the concrete defects of rectangular thin-walled pier columns, and there are internal defects in the concrete of rectangular thin-walled pier columns. Detection of blind spots

[0004] In terms of the detection of the thickness of the steel bar cover, the position of the steel bar and the spacing between the steel bars of the rectangular thin-walled pier column of the bridge, the traditional steel bar cover detector is still relied on. Rectangular thin-walled pier columns are detected, and on the basis of extension bars, it is only possible to detect the thickness of the reinforced protective layer, steel bar position and steel bar spacing of rectangular thin-walled pier columns within the range of 3m-4m in height. At present, there are no good detection methods and equipment for the detection of the thickness of the steel bar cover, the position of the steel bars and the spacing of the steel bars at the rectangular thin-walled pier column.

[0005] The height of rectangular thin-walled pier columns of bridges is generally above 20m, and some heights can even reach 100m or above. At present, there is still a lack of an effective means for comprehensive inspection of rectangular bridge pier columns.
