Description

Technical Field

[0001] The utility model relates to a mobile soot blowing device. Background Art

[0002] At present, after steel pipes are rolled, they need to be cooled on a cooling bed. During the cooling process, scale will be generated on the inner and outer surfaces of the steel pipes. The scale on the outer surface can fall off naturally, while the scale on the inner surface will remain inside the steel pipes. Therefore, a soot blowing device is required to blow away the scale inside the steel pipes. A hot-rolled steel pipe inner wall automatic soot blowing device is disclosed in a Chinese patent with the publication number CN215543356U. Before working, the soot blowing pipe of this soot blowing device needs to be adjusted to the proper position in the vertical and horizontal directions first, and then the position of the soot blowing pipe is fixed. During continuous operation, the position of the soot blowing pipe remains fixed while the steel pipe moves on the cooling bed until it aligns with the soot blowing pipe, and then air is blown into the steel pipe through the soot blowing pipe to blow away the scale inside the steel pipe. However, during continuous operation, the position of the soot blowing pipe is fixed, and there will be a certain deviation in the axial position of the steel pipe on the cooling bed. When the axial position deviation of the steel pipe is large, the steel pipe will hit the soot blowing pipe when moving on the cooling bed, which will cause the soot blowing pipe to be damaged and deformed, and then it cannot work properly.

[0044] The lifting driving mechanism 6 is installed on the mobile vehicle 2, connected to the lifting frame assembly 3 and is used to drive the lifting frame assembly 3 to move up and down, thereby driving the blowing pipe 4 to lift.

[0045] Specifically, when the steel pipe 7 moves to the working station on the cooling bed 100, the steel pipe 7 is blocked and stays in the working station. Then, the lifting drive mechanism 6 drives the lifting frame assembly 3 to move downward, thereby driving the blowing pipe 4 to move downward. When the blowing pipe 4 moves to the in-place position, the air outlet end of the blowing pipe 4 is aligned with the steel pipe 7 in the working station. Then, the moving drive mechanism 5 drives the moving vehicle 2 to move along the axial direction of the steel pipe 7 towards the steel pipe 7, thereby driving the blowing pipe 4 to move towards the steel pipe 7 to the in-place position, so that the air outlet end of the blowing pipe 4 is close to one end of the steel pipe 7 in the working station. Then, air is blown into the steel pipe 7 through the blowing pipe 4 to blow away and remove the scale inside the steel pipe 7. After the blowing is completed, the moving drive mechanism 5 first drives the moving vehicle 2 to move away from the steel pipe 7, thereby driving the blowing pipe 4 to move away from the steel pipe 7, so that the blowing pipe 4 is far away from the steel pipe 7. Then, the lifting drive mechanism 6 drives the lifting frame assembly 3 to rise, thereby driving the blowing pipe 4 to rise. At this time, the blowing pipe 4 is far away from the steel pipe 7 on the cooling bed 100. Then, the steel pipe 7 in the working station on the cooling bed 100 is sent to the next process, and the next steel pipe 7 moves to the working station, and then the above actions are repeated to continuously blow air into the steel pipe 7 to blow away and remove the scale inside the steel pipe 7. Among them, after blowing air into each steel pipe 7, the moving soot blowing device in the embodiment of the present application drives the blowing pipe 4 to move away from the steel pipe 7 and drives the blowing pipe 4 to rise, thereby making the blowing pipe 4 far away from the steel pipe 7 on the cooling bed 100, and further making the blowing pipe 4 avoid the moving steel pipe 7 on the cooling bed 100, avoiding the steel pipe 7 on the cooling bed 100 from hitting the blowing pipe 4 when moving, and further avoiding damage and deformation of the blowing pipe 4.

The adjusting mechanism is used to drive the mounting frame 13 to move up and down on the main frame body 12 to a proper position so as to adjust the installation height of the blowing pipe 4; specifically, when the lifting drive mechanism 6 drives the main frame body 12 to move up and down, it can drive the mounting frame 13 and the blowing pipe 4 to move up and down together, and further can drive the blowing pipe 4 to lift; further specifically, the adjusting mechanism drives the mounting frame 13 to move to a suitable height position on the main frame body 12, and further can adjust the installation height of the blowing pipe 4.

[0068] In summary, when the steel pipe 7 moves to the working station on the cooling bed 100, the steel pipe 7 is blocked and stays in the working station. Then, the lifting drive mechanism 6 drives the lifting frame assembly 3 to move downward, thereby driving the blowpipe 4 to move downward. When the blowpipe 4 reaches the in-place position, the air outlet end of the blowpipe 4 is aligned with the steel pipe 7 in the working station. Then, the moving drive mechanism 5 drives the moving cart 2 to move along the axial direction of the steel pipe 7 towards the steel pipe 7, thereby driving the blowpipe 4 to move towards the steel pipe 7 to the in-place position, so that the air outlet end of the blowpipe 4 is close to one end of the steel pipe 7 in the working station. Then, air is blown into the steel pipe 7 through the blowpipe 4 to blow away and remove the scale inside the steel pipe 7. After the air blowing is completed, the moving drive mechanism 5 first drives the moving cart 2 to move away from the steel pipe 7, thereby driving the blowpipe 4 to move away from the steel pipe 7, so that the blowpipe 4 is far away from the steel pipe 7. Then, the lifting drive mechanism 6 drives the lifting frame assembly 3 to rise, thereby driving the blowpipe 4 to rise. At this time, the blowpipe 4 is far away from the steel pipe 7 on the cooling bed 100. Then, the steel pipe 7 in the working station on the cooling bed 100 is sent to the next process, and the next steel pipe 7 moves to the working station, and then the above actions are repeated to continuously blow air into the steel pipe 7 to blow away and remove the scale inside the steel pipe 7. After blowing air into each steel pipe 7, the moving soot blowing device according to the embodiment of the present application drives the blowpipe 4 to move away from the steel pipe 7 and drives the blowpipe 4 to rise, thereby making the blowpipe 4 far away from the steel pipe 7 on the cooling bed 100, and further making the blowpipe 4 avoid the moving steel pipe 7 on the cooling bed 100, avoiding the steel pipe 7 on the cooling bed 100 hitting the blowpipe 4 when moving, and further avoiding damage and deformation of the blowpipe 4.
