Automatic conveying, derusting and painting equipment for bridge building materials

Abstract

The invention discloses automatic conveying, derusting and painting equipment for bridge building materials, and belongs to the technical field of bridge engineering. The automatic conveying, derusting and painting equipment for bridge building materials comprises a treatment box, two annular grooves are symmetrically formed in the inner wall of the circumference of a conveying cylinder, adjusting rings are slidably connected into the annular grooves, a plurality of conveying columns are annularly arranged on the outer walls of the adjusting rings at equal intervals, and a plurality of conveying sleeves annularly sleeve the outer walls of the adjusting rings at equal intervals; and the output end of a motor B penetrates through the interior of the conveying cylinder, extends into a circular groove and is sleeved with a gear B, the gear B is in meshed connection with annular inner teeth formed in the outer walls of the circumferences of the adjusting rings, and the steel bars are conveyed forwards while rotating due to close cooperation of the structures, so that rust removal is thorough, painting is uniform, and the situation that the steel bars cannot be painted does not exist, so that the time is saved, the derusting and painting effects are improved, normal proceeding of the later bridge engineering is guaranteed, meanwhile, the quality of the bridge is guaranteed, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, and more specifically relates to a bridge building material automatic conveying derusting and painting equipment. Background technique [0002] Bridges are very common now. Bridges have made our transportation much more convenient. In recent years, the improvement of my country's bridge construction capabilities is obvious to all. China's bridge construction records have been shocking the world, constantly creating miracles, crossing mountains, rivers, and oceans. It seems that there is no terrain It is beyond our reach. However, there has always been a fundamental disadvantage in bridge construction, and it has not been well resolved now, that is, the service life of bridges is very limited, because the materials for bridge construction are basically steel, and steel is very fragile under the wind and sun. It is easy to rust, the hardness is reduced, and it is easy to collapse. The ex...

However, there has always been a fundamental disadvantage in bridge construction, and it has not been well resolved now, that is, the service life of bridges is very limited, because the materials for bridge construction are basically steel, and steel is very fragile under the wind and sun. It is easy to rust, the hardness is reduced, and it is easy to collapse. The existing grinding and rust removal device is not effective, and it relies on human assistance. The efficiency of rust removal is very low, and it is urgent to make changes

The prior art publication number is CN111774238A, which provides a bridge building material automatic conveying derusting and painting equipment. The device is equipped with an automatic feeding and conveying mechanism in the empty warehouse, and the side away from the centerline is fixedly connected. The inclined plate and the limit block Sliding connection, the empty chamber is also equipped with a grinding, derusting and painting mechanism. The grinding, derusting and painting mechanism includes a processing chamber. The rotating shaft is rotationally connected with the inner wall of the lower side of the processing chamber. The third conveyor belt and the rotary transmission wheel are frictionally driven, and the rotary transmission wheel is fixedly connected to the drive shaft, so that the steel bars and other materials needed for construction in the bridge construction project are stored and polished and derusted by themselves, and a delivery device is provided. Although this device is beneficial There are many effects, but the following problems still exist: the device realizes simple functions by using a complex structure, which increases the cost and budget, and the device is transported by the conveyor belt for derusting and painting, and the steel bars cannot be effectively fixed. The phenomenon of self-rolling will occur, so that not only the rust removal is not complete, but also the paint is not uniform, and there are places that cannot be covered. The quality of the bridge cannot be guaranteed, the service life is reduced, and there are potential safety hazards. In view of this, we propose a bridge building material automatic conveying derusting and painting equipment
