The working principle of the municipal road crack detection device provided by the utility model is as follows:

in the device, the model of the detector 2 is ZBL-F800, and in an initial state, an output shaft of the electric push rod 16 is in an extending state;

before detecting a road crack, the device is carried to a specified detection position and put down, then two bidirectional screws 14 are rotated to enable two corresponding connecting plates 15 to move away from each other, so that two corresponding protective covers 17 can be separated from each other, the transducer 3 in the protective covers is gradually unfolded, and after the two transducers 3 are completely exposed, an output shaft of an electric push rod 16 is started to retract, the protective covers 17 are brought upwards, and the bottoms of the transducers 3 can protrude;

then, a second motor is started in a forward direction, the second gear is meshed with a third gear to drive corresponding threaded sleeves 12 to rotate, then the two threaded sleeves 12 rotate simultaneously through transmission between a synchronizing wheel and a synchronizing belt, so that the two transmission screws 13 drive the belt connecting plate 4 to descend under the limitation of a vertical rod, the transducer 3 starts to descend at the moment, the second motor is closed after the transducer is contacted with the road surface, and the detector 2 is started, so that the first detection can be carried out;

after the first detection is finished, in order to improve the accuracy of detection data, the distance between the two transducers 3 needs to be adjusted and the detection is carried out, so that the second motor can be started reversely, the transducers 3 are brought up to the original position, then the output shaft of the first motor is started in a forward direction for a circle, the central rod 11 can be driven to rotate through the meshing between the two first gears, so that the two connecting shafts 8 are driven to rotate under the meshing between the first bevel gears and the second bevel gears, the rotation directions of the two connecting shafts 8 are opposite, and then the two movable boxes 6 are moved along with the end of the circle of rotation of the output shaft of the first motor by the meshing relationship between the two missing teeth 9 and the tooth plate 10, meshing is formed when the teeth on the missing teeth 9 contact the teeth on the tooth plate 10, so that the two movable boxes 6 are linearly and horizontally moved away from each other, but the distance between the two transducers 3 is adjusted, then the second motor can be started forward again, and secondary detection can be carried out, so that reciprocating motion is carried out, and the above mode can be adopted when the distance between the two transducers 3 needs to be adjusted until the detection is finished.

the utility model provides a municipal road crack detection device, which can realize the adjustment of the distance between two movable boxes 6 through the linkage between a motor I and a central rod 11 and a connecting shaft 8 and the engagement between a missing tooth 9 and a tooth plate 10, thereby accurately adjusting the distance between two transducers 3 under the condition of not manually holding the transducers 3 for detection, thereby detecting a plurality of groups of data, in addition, the transducers 3 can be always contacted with the road pavement through the transmission between a transmission screw 13 and a threaded sleeve 12, the detection accuracy is improved while the workload of manual operation is reduced, and the transducers 3 can be surrounded and protected through a protective cover 17 when not in use, thereby reducing the possibility of damage caused by the influence of foreign objects.
