Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0023] refer to Figure 1 to Figure 4 , the vehicle-mounted pavement crack detection system inspection device based on variable depth cracks includes a rubber connector 1, a cross bar 2, a rubber 3, a bracket 4, a base 5, a short bracket 6, a fixed shaft 7 and a connector 8.

[0024] The rubber connector 1 is made of a circular steel pipe, the rubber 3 is made of a rectangular rubber plate, and the three rubber connectors 1 are bonded and fixedly connected to both sides and the middle of the rubber 3 respectively. The crossbar 2 is made of round steel, and two hooks are welded on the two ends of the round steel, and the three crossbars 2 penetrate into the middle circular holes of the three rubber connectors 1 . Support 4 is processed for round steel, welds a ring on the upper end of round steel, base 5 is made of rectangular steel plate, base 5 is placed on the level...

Abstract

The invention discloses a vehicle-mounted road surface crack detection system detection device based on the variable-depth cracks and aims at solving the checking problem of measurement results of different depths of cracks detected by a vehicle-mounted road surface crack detection system. The vehicle-mounted road surface crack detection system detection device based on the variable-depth cracks is mainly composed of rubber connecting pieces (1), cross bars (2), rubber (3), supports (4), a base (5), short supports (6), fixing shafts (7) and connecting pieces (8). The vehicle-mounted road surface crack detection system detection device based on the variable-depth cracks is provided and is variable in crack depth, simple in device structure, reliable in performance, easy and convenient to operate and install and low in cost.

Description

technical field [0001] The invention relates to an auxiliary device for detection equipment in the field of traffic detection, more specifically, it is a detection device for a vehicle-mounted road surface crack detection system based on variable-depth cracks. Background technique [0002] Pavement cracks, as a common pavement disease, have been paid more and more attention by highway management and maintenance departments. At present, pavement performance data mainly rely on manual measurement, which is expensive, slow, affects traffic and is unsafe. Variable crack depth detection is one of the important steps of the vehicle-mounted pavement crack detection system. At present, there is no effective inspection method for the detection system to measure the crack depth. Therefore, it is very necessary to design a verification device that can reasonably evaluate the variable crack depth of the vehicle-mounted pavement crack detection system. Contents of the invention [00...
