Bridge pier column detection device and method

Abstract

The invention provides a bridge pier column detection device and method, and the device comprises: a climbing device which surrounds and is detachably disposed at the periphery of a pier column, and is used for moving up and down along the pier column; and a surrounding detection device which is arranged at the upper part of the climbing device and is used for carrying out surrounding detection on the pier column, wherein the climbing device is uniformly connected with a plurality of brackets, and the surrounding detection device is connected with the climbing device through the brackets. The brackets are connected with a plurality of cameras which are uniformly distributed, and the plurality of cameras jointly capture full-angle images of the pier stud; the climbing device is of a modular structure and comprises a plurality of climbing assemblies which are assembled in a matched mode according to the diameter of a pier column; and the climbing device, the surrounding detection device and the camera are all electrically connected with the comprehensive control equipment, so that movement control over the climbing device is achieved, and data detected and captured by the surrounding detection device and the camera are processed and displayed.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a bridge pier detection device and method. Background technique [0002] At present, the appearance inspection of bridge piers, especially high piers, requires the use of unmanned aerial vehicles for close-range photo observation, and non-contact measuring instruments such as telescopes or long-distance observers. The detection efficiency is low, and it is greatly affected by the weather. It can only be used in good weather Observation is carried out under the conditions of good visibility and good light. At the same time, the existing detection methods and technologies have low accuracy and precision in the observation and identification of circular pier appearance defects, and cannot closely inspect the appearance of circular high pier. Disease identification and detection. [0003] At present, the detection of the thickness of steel bar cover, steel bar position and ...

Problems solved by technology

[0002] At present, the appearance inspection of bridge piers, especially high piers, requires the use of unmanned aerial vehicles for close-range photo observation, and non-contact measuring instruments such as telescopes or long-distance observers. The detection efficiency is low, and it is greatly affected by the weather. It can only be used in good weather Observation is carried out under the conditions of good visibility and good light. At the same time, the existing detection methods and technologies have low accuracy and precision in the observation and identification of circular pier appearance defects, and cannot closely inspect the appearance of circular high pier. Disease identification and detection

[0003] At present, the detection of the thickness of steel bar cover, steel bar position and steel bar spacing of bridge pier columns still relies on the traditional steel bar cover detector. Manual detection of steel bar cover, steel bar position and steel bar spacing can only be used for circular pier columns within a height range of about 2m. For detection, on the basis of the extension bar, it can only detect the thickness of the protective layer of the circular pier column within the range of 3m-4m, the position of the steel bar and the spacing of the steel bars. At present, there are no good detection methods and equipment for the detection of the thickness of the protective layer of steel bars, the location of steel bars, and the spacing of steel bars at pier columns.
