Abstract

The invention discloses a knocking load applying device for knocking scan type bridge damage detecting, which comprises a traveling car, a knocking device and a knocking control device. The traveling car can move on a to-be-detected bridge; the knocking device is arranged on the traveling car, can generate a knocking load, and can transfer the knocking load to the to-be-detected bridge through the traveling car; and the knocking control device is connected with the knocking device, and is used for controlling the knocking device to generate a preset knocking load. The knocking load applying device for knocking scan type bridge damage detecting provided by the invention can continuously and steadily apply the knocking load with preset frequency and amplitude values to the to-be-detected bridge, so as to meet the requirement of knocking scan type bridge damage detecting.

Description

technical field [0001] The invention relates to a knocking system, in particular to a knocking load applying device for knocking and scanning bridge damage detection. Background technique [0002] With the advancement of science and technology and the improvement of transportation demand, the number of bridges for various highways and rail transits has increased rapidly. During the use of these bridges, they are constantly eroded by external environments such as temperature changes, strong winds, and rainfall. At the same time, they are eroded by vehicles The long-term repeated action of load and vehicle impact, and some bridges will also be damaged by natural disasters such as floods and earthquakes. With the increase of service life, bridges generally experience different degrees of fatigue effects and aging phenomena. External damage has caused many bridges to become dangerous bridges in a certain sense. There have been a large number of collapse instances of bridges at h...
