In the cleaning operation process of the tunnel, as the pavement in the tunnel is generally laid in the later construction stage, when the side wall of the tunnel is built in the earlier stage, the pits and holes on each road section are relatively more and uneven, and the working condition is complex. In addition, the side brush of the currently used sweeper cannot be adjusted, so that the side brush of the sweeper is seriously worn and has high replacement frequency.

Through market research, the current sweeper can be divided into two main types according to the structure of the side brush, one type is a sweeper with an unadjustable side brush, and the cost of the sweeper is lower, but the problems are solved. The other is to use a lifting mechanism to lift the whole edge brush, and the abrasion of the edge brush is reduced by reducing the contact time between the edge brush and the ground. When the cleaning device is used, the side brush is put down to be in contact with the ground for cleaning, and when the cleaning device is not used, the side brush is lifted, so that the side brush is prevented from being in continuous contact with the ground, and invalid operation is avoided. The integral lifting type sweeper has the advantages that the service life of the side brush is prolonged, but the defects of the side brush are obvious, the lifting structure is relatively complex, the integral manufacturing cost is high, the subsequent maintenance and overhaul projects of the sweeper are increased, and the tasks of staff are aggravated.
