However, in this design, the cleaning disc cannot move horizontally during rotation. Especially when the crack itself is elongated, a worker is required to push the main box to move at the crack so that the cleaning disc on one side of the main box can clean the crack. This design defect easily leads to a time-consuming overall cleaning process.

[0006] The technical solution of the utility model is as follows: a road crack detection device comprises a movable seat, wherein the bottom of the movable seat is symmetrically provided with rail grooves, a threaded rod is movably connected in the rail groove, the outer side of the threaded rod is threadedly connected with a sliding seat, a driving element is installed at the bottom of the sliding seat, a rotating shaft is movably connected to the bottom output end of the driving element, a cleaning disc is fixedly connected to the bottom of the rotating shaft, and a cleaning sweeping strip is fixedly connected to the bottom annular array of the cleaning disc.

[0007] Preferably, a thread groove is provided through the middle of the slide seat, and the thread groove and the threaded rod are matched in size.

[0016] Technical effects and advantages of the utility model:

[0017] The utility model symmetrically opens rail grooves at the bottom of the movable seat, and a threaded rod that can be controlled to rotate forward / reverse is arranged in the rail groove. When it is necessary to clean the cracks before detection, the movable seat is first moved to the area to be detected, and the telescopic element is started to shrink so that the overall height of the movable seat is lowered until the cleaning sweeping strip contacts the ground. Then the staff can start the threaded rod to rotate forward / reverse, so that the slide seat threadedly connected to the bottom of the threaded rod can synchronously move horizontally back and forth at the bottom of the movable seat with the forward / reverse reciprocating rotation of the threaded rod. In particular, the driving element at the bottom of the slide seat synchronously drives the rotating shaft and the cleaning sweeping strip at the bottom of the rotating shaft to rotate at high speed, so as to clean the debris at the cracks. The cleaning work is particularly convenient for workers to carry out cleaning work. In particular, when cleaning, the worker can start the dust suction fan to rotate at high speed and form negative pressure at the bottom of the moving seat. At this time, the debris at the cleaning location is sucked into the inner cavity of the moving seat through the dust collecting channel and temporarily stored in the dust collecting bin. This design can solve the problem of needing to push the moving seat back and forth to move slender cracks. The present design cannot push the moving seat frequently. The cleaning work of debris and other foreign matters at the cracks can be completed by only two sets of high-speed rotating cleaning discs and cleaning sweeps that move back and forth horizontally at the bottom of the moving seat. In particular, when the cleaning work is completed, the cracks after cleaning can be photographed by a camera and the crack size data can be collected for subsequent repair work at the cracks.

By symmetrically opening the rail groove 16 at the bottom of the mobile seat 1, and arranging the threaded rod 17 that can be controlled to rotate forward / reverse in the rail groove 16, when it is necessary to clean the cracks before detection, the mobile seat 1 is first moved to the area to be detected, and the telescopic element 10 is started to shrink so that the overall height of the mobile seat 1 is reduced until the cleaning sweeping strip 23 contacts the ground, and then the staff can start the threaded rod 17 to rotate forward / reverse, so that the slide seat 24 threadedly connected to the bottom of the threaded rod 17 moves along with the threaded rod 17. The forward / reverse reciprocating rotation is synchronously performed horizontally reciprocating at the bottom of the mobile seat 1. In particular, the driving element 27 located at the bottom of the slide 24 synchronously drives the rotating shaft 28 and the cleaning sweeping strip 23 located at the bottom of the rotating shaft 28 to rotate at high speed to clean the debris at the crack. In particular, when performing the cleaning work, the staff can start the dust suction fan 19 to rotate at high speed and form a negative pressure at the bottom of the mobile seat 1. At this time, the cleaned debris is sucked into the inner cavity of the mobile seat 1 through the dust collecting channel 20 and temporarily stored in the dust collecting bin 5. This design can solve the problem of needing to push the mobile seat 1 back and forth to move for slender cracks. The present design cannot frequently push the mobile seat 1. It only needs to use two sets of high-speed rotating cleaning discs 22 and the cleaning sweeping strip 23 to move horizontally back and forth at the bottom of the mobile seat 1 to complete the cleaning of debris and other foreign objects at the crack. In particular, when the cleaning work is completed, the cleaned crack can be photographed and the crack size data can be collected through the camera 13 for subsequent repair work on the crack.

[0034] Working principle of the utility model: In the present design, a rail groove 16 is symmetrically opened at the bottom of the mobile seat 1, and a threaded rod 17 capable of controlling forward / reverse rotation is arranged in the rail groove 16. When cleaning work is required before crack detection, the mobile seat 1 is first moved to the detection area, and the telescopic element 10 is activated to contract so that the overall height of the mobile seat 1 is lowered until the cleaning sweeping strip 23 contacts the ground. Then, the staff can activate the threaded rod 17 to perform forward / reverse reciprocating rotation, thereby causing the slide 24 threadedly connected to the bottom of the threaded rod 17 to perform horizontal reciprocating movement at the bottom of the mobile seat 1 synchronously with the forward / reverse reciprocating rotation of the threaded rod 17. In particular, the driving element 27 at the bottom of the slide 24 synchronously drives the rotating shaft 28 and the cleaning sweeping strip 23 at the bottom of the rotating shaft 28 to perform high-speed reciprocating movement. The cleaning fan 19 can rotate at a high speed to form a negative pressure at the bottom of the movable seat 1. At this time, the cleaned debris is sucked into the inner cavity of the movable seat 1 through the dust collecting channel 20 and temporarily stored in the dust collecting bin 5. This design can solve the problem of moving the movable seat 1 back and forth to move the slender cracks. The present design cannot frequently push the movable seat 1. The cleaning work of debris and other foreign matters at the cracks can be completed by two sets of high-speed rotating cleaning discs 22 and cleaning sweeping strips 23 that move back and forth horizontally at the bottom of the movable seat 1. In particular, when the cleaning work is completed, the cleaned cracks can be photographed and the crack size data can be collected through the camera 13 for subsequent repair work on the cracks.
