[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , Figure 2 and Figure 4 In the embodiment of the utility model, a highway bridge expansion joint cleaning device includes a mobile trolley 1, a cleaning roller 8 and a dust removal mechanism 9. A fixed frame 5 is installed on the mobile trolley 1, an electric telescopic rod 6 is installed on the fixed frame 5, a roller frame 7 is installed at the bottom of the electric telescopic rod 6, a cleaning roller 8 is installed in the middle of the roller frame 7, and one end of the cleaning roller 8 is directly connected to the output shaft of a motor 10 installed on the outer wall of the roller frame 7. A dust removal mechanism 9 is installed on the mobile trolley 1 behind the fixed frame 5, and an exhaust fan 2 is installed on the dust removal mechanism 9. The two sides of the dust removal mechanism 9 are respectively connected to a first suction pipe 11 and a second suction pipe 12, and the first suction pipe 11 passes through the moving trolley 1 and is connected to a dust hood 13 arranged below the moving trolley 1. The dust hood 13 is tilted toward the cleaning roller 8, so that the raised dust can be better sucked in. The second suction pipe 12 passes through the moving trolley 1 and is threadedly connected to a suction nozzle 14 arranged below the moving trolley 1. The first suction pipe 11 and the second suction pipe 12 are respectively installed with a first suction pipe control valve 15 and a second suction pipe control valve 4. The first suction pipe control valve 15 and the second suction pipe control valve 4 are respectively used to control the on-off of the first suction pipe 11 and the second suction pipe 12, so as to facilitate the selection of the suction mode according to actual needs.

[0021] See also Figure 3The dust removal mechanism 9 includes a dust removal cylinder 901, a filter screen 902, an end cover 903, an ash discharge valve 904 and a support leg 905. Four support legs 905 are installed at the bottom of the dust removal cylinder 901. A detachable filter screen 902 is installed in the dust removal cylinder 901. The end cover 903 is threadedly connected to the top of the dust removal cylinder 901. An ash discharge valve 904 is installed at the bottom of the dust removal cylinder 901. When the filter screen 902 needs to be cleaned or replaced, the end cover 903 can be unscrewed first, and then the filter screen 902 can be taken out.

[0022] See also Figure 1-2 The mobile trolley 1 includes a vehicle plate 101, directional wheels 102, steering wheels 103 and a direction handle 104.

[0023] The working principle of the utility model is:

[0024] During use, the personnel hold the direction handle 104 to push the mobile car 1 to move above the expansion joint of the highway bridge, so that the bottom end of the second suction pipe 12 faces the expansion joint, and then the electric telescopic rod 6 drives the cleaning roller 8 to move downward close to the expansion joint, and then the motor 10 is started. The motor 10 drives the cleaning roller 8 to rotate at high speed to clean the expansion joint. The dust raised by the cleaning is sucked into the dust collection cylinder 901 through the dust hood 13 and the first suction pipe 11, and is intercepted by the filter 902 and falls to the bottom of the dust collection cylinder 901. Then, the large particles of impurities in the expansion joint will be sucked into the second suction pipe 12 by the suction nozzle 14, and then are sucked into the dust collection cylinder 901 through the second suction pipe 12, and are intercepted by the filter 902 and fall to the bottom of the dust collection cylinder 901. The filtered air is discharged from the exhaust fan 2.
