Bridge concrete flaw detection equipment based on ultrasonic principle

Abstract

The invention belongs to the technical field of bridge engineering, and particularly relates to bridge concrete flaw detection equipment based on the ultrasonic principle, and the bridge concrete flaw detection equipment comprises an upper fixing structure, a lower fixing structure, an ultrasonic transmitter and a water pipe; the upper fixing structure and the lower fixing structure are respectively fixed at the bottom of a bridge floor and a bridge bottom; the water pipe is used for connecting the upper fixing structure and the lower fixing structure, and the ultrasonic transmitter is movably connected with the lower fixing structure. By means of the strong buoyancy effect of foam plastic or sponge, buoyancy is converted into pulling force through water and pulleys, movement of the ultrasonic transmitter is achieved, the fixing effect of the ultrasonic transmitter after completion is achieved through an upper locking structure and a lower locking structure, and a control pressure valve can be arranged to control the flow speed of outflow water; the falling speed of the ultrasonic transmitter is further controlled; the vertical movement of the ultrasonic transmitter is realized through water feeding and water discharging, so that bidirectional detection is realized.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, in particular to a bridge concrete flaw detection device based on the principle of ultrasonic waves. Background technique [0002] A bridge generally refers to a structure erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern and fast-developing transportation industry, bridges are also extended to bridges over mountain streams, unfavorable geology or other traffic needs to be erected to make traffic more convenient. Bridges are generally composed of superstructure, substructure, supports and auxiliary structures. The superstructure, also known as bridge span structure, is the main structure for crossing obstacles. The substructure includes abutments, piers and foundations. The supports are the span structure and pier. Or the force transmission device set at the support place of the bridge abutment, and the auxiliary stru...

Problems solved by technology

[0006] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a bridge concrete flaw detection device based on the ultrasonic principle, which is used to solve the problem of time-consuming and labor-intensive assembly and maintenance of the prior art, low efficiency, unstable connection and structural strength. Low; most of the existing flaw detection devices can only be used for horizontal inspection of the bridge deck. If longitudinal inspection is required, drones equipped with probes are required for inspection, but the cost of such inspection has increased significantly, and the height of the bridge pier is too high. , the battery life of the UAV will become a huge problem when it is flying.
