[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When the H-shaped steel structure beam spraying machine with a surface cleaning function needs to be sprayed on the H-shaped steel structure, the staff can place the device on the H-shaped steel structure, so that the roller drives the entire device to move, and at the same time, start the hydraulic push rod to make the cleaning column contact the surface of the H-shaped steel structure.

During the movement effect, the sliding rod can be driven to move, and the hydraulic push rod can be driven to move. By utilizing the movement effect, the cleaning column can drive the cleaning hair to move up and down along the surface of the H-shaped steel structure. At the same time, by utilizing the friction between the device and the surface of the H-shaped steel structure when moving, the cleaning column can be driven to rotate, thereby utilizing this effect to enhance the cleaning effect of the device on the surface of the H-shaped steel structure.

[0015] (3) The spraying machine for H-shaped steel structure beams with a surface cleaning function can utilize the extrusion force on the surface of the H-shaped steel structure to move the extrusion rod when the cleaning column moves up and down. Under the effect of the movement, the jet extrusion plate can be moved. The movement effect of the jet extrusion plate can be utilized to discharge the gas inside the cleaning column through the jet hole. The blowing effect of the gas is utilized to enhance the cleaning effect of the device on the surface of the H-shaped steel structure.

[0016] (4) The sprayer for H-shaped steel structure beams with a surface cleaning function can make the rotating plate rotate under the extrusion pressure of the side wall of the H-shaped steel structure when the cleaning column moves up and down, so that the auxiliary cleaning column can be moved laterally by utilizing the rotation effect. At the same time, the electric telescopic rod can be started to make the auxiliary cleaning column repeatedly move longitudinally. Under this coordination, the cleaning area of ​​the surface of the H-shaped steel structure by the device can be increased, thereby enhancing the cleaning effect of the device. On the other hand, under the movement effect of the auxiliary cleaning column, the push plate can be moved under the action of the pull rod, so that the gas inside the auxiliary cleaning column can pass through the small hole by utilizing its movement effect, and then act on the surface of the H-shaped steel structure, thereby further enhancing the cleaning effect of the device on the surface of the H-shaped steel structure.
