Road and bridge crack automatic detection and repair integrated robot

Abstract

The invention relates to a road and bridge crack automatic detection and repair integrated robot which comprises a rack, and a flaw detection assembly is arranged on the front side of the rack; a base plate is arranged on the upper portion of the machine frame, and a repairing integrated robot is arranged on the base plate. The flaw detection assembly is provided with a plurality of pulse probes, and the pulse probes are used for acquiring reflected sound wave signals of a roadbed surface and inputting the acquired reflected sound wave signals into the control device; the control device acquires the reflected sound wave signal and then converts the reflected signal into an analog signal; the control device is used for acquiring an analog signal, acquiring an amplitude change corresponding to the analog signal based on the analog signal, comparing the amplitude change with a reference amplitude to acquire an amplitude deviation state, acquiring a crack state based on the amplitude deviation state, and acquiring a repair plan arranged in the control device based on the crack state execution unit; and based on the repair plan control device, the repair integrated robot is driven by the control device to select the corresponding repair equipment to repair the crack under the control of the tool changing control assembly.

Description

technical field [0001] The invention relates to the technical field of road and bridge crack detection and repair, in particular to an integrated robot for automatic detection and repair of road and bridge cracks. Background technique [0002] The maintenance of existing road and bridge cracks basically relies on people to identify whether there are cracks, which can only repair the cracks that have already appeared on the surface, but cannot repair some potential cracks. And the current maintenance methods basically rely on people. For some dangerous areas such as viaducts and tunnels, manual maintenance can only be carried out at a fixed time, which is not conducive to timely repair of cracks. In the prior art disclosed, such as the publication number: "CN110161047A", an integrated robot for automatic detection and repair of road and bridge cracks is disclosed, which is used for automatic detection and repair of uneven road surfaces and bridge deck cracks. The robot is eq...

Problems solved by technology

[0003] The above discloses the use of robots to replace labor, but the camera module used to detect cracks, this method can only obtain the cracks that have already appeared, but it cannot detect some potential cracks in the roadbed.

Of course, in the existing disclosed technologies, flaw detectors are also used to obtain potential cracks in the roadbed, but because the roadbed contains a large number of pores (caused by roadbed materials, such as asphalt roadbeds containing stones), the flaw detection equipment cannot Very good at discerning the difference between these pores and cracks
