Description

Technical Field

[0001] The utility model belongs to the field of bridge damage detection, and specifically relates to a bridge internal defect detection device. Background Art

[0002] During their service, bridges are constantly eroded by external factors such as rain, wind and sand, as well as damaged by vehicle loads, so it is very important to inspect bridges regularly.

[0003] A Chinese patent with announcement number CN219364316U discloses an internal damage detection device for bridge inspection, which relates to the technical field of bridge damage detection. The internal damage detection device for bridge inspection includes a cart, a detection device body is placed on the top of the cart, and clamping mechanisms are provided on the left and right sides of the detection device body. A cavity is formed inside the cart, and a rotating mechanism is accommodated inside the cavity. A driving mechanism is provided at the driving end of the rotating mechanism, and a linkage mechanism is provided at the coupling point between the rotating mechanism and the clamping mechanism; when the driving mechanism is driven, the rotating mechanism drives the clamping mechanism to move horizontally on the top of the cart through the linkage mechanism, so as to clamp and fix the position of the detection device body. The internal damage detection device for bridge inspection provided by the utility model has the advantage of being able to clamp and fix the position of the detection device body, thereby improving the stability of the detection device body during detection.

[0004] However, when the above-mentioned comparative document is actually used, rainwater and debris can easily enter the cart through the limiting slide groove, which not only easily causes damage to the motor and other components in the cart, but is also very difficult to clean. In addition, the detection device body needs to be placed in the center of the cart during use, and manual placement cannot accurately place it in the center of the cart. When the clamping mechanism fixes the detection device body, the clamping plate will push the detection device body to slide, causing friction and damage between the bottom of the detection device body and the cart.

[0005] In view of this, the present utility model is proposed. Utility Model Content
