The device is moved to a place where bridge concrete is broken and steel bars are exposed through the universal wheels 2 and the push rods 3, water is filled in the water storage tank 4, a heating plate 5 at the bottom of the water storage tank 4 is started, and water is properly heated and warmed; the rust remover is mixed with water according to a proper proportion and then is filled in the liquid storage tank 8, a worker picks up the handle 18, presses a button on the handle 18 to start the motor 19, drives the polishing head 24 to rotate through the driving shaft 20, and the eccentric block 21 is arranged on the driving shaft 20, so that the polishing head 24 vibrates while rotating due to the existence of the eccentric block 21, the polishing head 24 is attached to a place where concrete needs to be polished and cleaned, broken concrete and residual concrete on exposed steel bars are removed, the polishing speed of the concrete can be improved due to the vibration effect of the polishing head 24, the generated vibration can act on the steel bars, the loosening of a rust layer on the steel bars can be facilitated, preparation is made for subsequent high-pressure water spraying rust removal, and the rust removal efficiency is improved.
The air pump 14 is started in the polishing process, a large amount of dust and fragments are generated in the polishing process of concrete, the main components of the dust and fragments are quartz particles, quartz dust, sand grains, sand dust and the like, the dust and the fragments are accumulated in the dust collection frame 23, a filter screen 26 is arranged at the pipe orifice of the dust collection pipe 15 in the dust collection frame 23, the dust and the fragments with proper sizes are sucked into the dust collection pipe 15, and larger particles can directly fall to the ground; the dust and the scraps are discharged to the bottom of the water storage tank 4 through the exhaust pipe 16, a large number of bubbles are generated at the bottom of the water storage tank 4, the bubbles rise to the stirring effect on the water storage tank 4, the dust and the scraps are fully stirred in water, and the water is changed into sandy water; in this way, dust in the working environment is reduced, and the sand-carrying water generated by local material can improve the high-pressure water spraying rust removal effect.
In the polishing process, the prepared rust remover passes through the mounting frame 22 to reach the back of the polishing head 24 through the liquid supplementing pipe 9, so that the solution is discharged from the liquid outlet 25 on the back of the polishing head 24, and the first is that: the temperature of the polishing head 24 can be reduced, and the polishing effect and speed can be improved; second,: the rust remover flows down from the polished area, polishing is carried out from top to bottom in the working process, so that the sprayed rust remover can contact with the steel bars in the polished area, and the excessive rust remover flows to the surface of the steel bars below to remove rust or loosen rust through the action of the rust remover.
After the concrete is cleaned, after the rust remover is acted, starting a water pump 10, pumping the heated sand-water mixture into a water outlet pipe 12 through a water suction pipe 11, spraying sand-carrying water onto the surface of the steel bar through a high-pressure spray nozzle 13, wherein the high-pressure spraying sand-carrying water combines the functions of high-pressure water impact and sand grain friction, so that rust on the surface of the steel bar can be effectively removed, and the surface of the steel bar is ensured to be clean and smooth; the water with sand is heated, so that the iron rust can be softened and dissolved, the rust removing effect is further improved, and meanwhile, the rust remover is cleaned.
After rust cleaning is completed, waiting for moisture to be dried in the sun, filling new concrete by workers, and completing maintenance work of the bridge after the concrete is solidified.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
