Description

Technical Field

[0001] The invention relates to the technical field of dust cleaning devices, and in particular discloses a dust cleaning device for a heating furnace base. Background Art

[0002] The heating furnace base is a base structure used to fix the heating furnace and facilitate the stable placement of the heating furnace. The heating furnace base is generally a steel frame type, which has the advantages of structural stability and high temperature resistance; the dust and dirt on the heating furnace base is generally dust accumulation or slag, which will bring a series of serious problems.

[0003] Dust and dirt usually contain corrosive substances, which will corrode the surface of the base and even the heating furnace. If things go on like this for a long time, it will cause damage to the base and the heating furnace, destroy the stability of the base, and cause serious safety hazards. Secondly, dust and dirt will lead to a decrease in the air quality in the working environment. Since the heating furnace is in a high temperature state during the heating process, the harmful substances in the dust and dirt will evaporate into the air due to the increase in temperature, causing serious impact on the air quality, and further damaging the health of the staff. In addition, a large amount of dust and dirt will increase the frequency of equipment maintenance, which not only increases the maintenance cost of the equipment, but also greatly reduces work efficiency.

[0027] Among them, the motion trajectory of the semicircular brush 31 is: when the third slide rail 41 and the track 42 are completely overlapped, the semicircular brush 31 is in the initial position; the servo motor 29 drives the semicircular brush 31 to rotate 90° in the clockwise direction through the belt 30, and then, the servo motor 29 drives the semicircular brush 31 to rotate 90° in the counterclockwise direction and return to the initial position, then, the servo motor 29 drives the semicircular brush 31 to rotate 90° in the counterclockwise direction, and then, the servo motor 29 drives the semicircular brush 31 to rotate 90° in the clockwise direction again and return to the initial position; when the device is running, the servo motor 29 and the semicircular brush 31 repeat this motion trajectory.

[0028] The working principle of the present invention is: First, the staff moves the device to the place where the scale needs to be cleaned on the heating furnace base through the pulley 32. Then, the staff rotates the handle 616 to rotate the threaded rod 615 in the first fixed block 613 and the second fixed block 614. Since the threads opened in the first fixed block 613 and the second fixed block 614 are in opposite directions, when the threaded rod 615 rotates clockwise or counterclockwise, the first fixed block 613 and the second fixed block 614 move in relative or opposite directions, thereby driving the first support rod 605 and the second support rod 606, the third support rod 607 and the fourth support rod 608 to rotate in relative or opposite directions, so that the angle formed between the first support rod 605 and the second support rod 606, the third support rod 607 and the fourth support rod 608 is reduced or expanded, and then the lifting frame 5 is moved along the Y axis. The lifting frame 5 moves up or down in the Y-axis direction, thereby making the lifting frame 5 move up or down in the Y-axis direction and adjusting the height of the lifting frame 5 to the optimal position; then, the staff starts the first motor 11, so that the first motor 11 drives the support shaft 10 to rotate, so that the first support arm 12 and the second support arm 13 on the support shaft 10 rotate to the optimal height position in the first quadrant; furthermore, the staff starts the cylinder 17, the cylinder 17 drives the second receiving plate 18, and makes the third receiving plate 19 fastened to the second receiving plate 18 slide on the first support arm 12 and the second support arm 13 through the second slide rail 14 and the second slider 44, and makes the third receiving plate 19 slide to the optimal position; at this time, the first roller brush 25, the second roller brush 27 and the semicircular brush 31 are all arranged at the position of the heating furnace base where dust and dirt need to be cleaned.

[0029] Afterwards, the staff starts the second motor 22 and the servo motor 29, the second motor 22 drives the first gear 23 to rotate, and then the second gear 24 meshing with the first gear 23 rotates, and further, the rotation of the second gear 24 causes the third gear 26 meshing therewith to rotate, thereby rotating the first roller brush 25 connected to the second gear 24 and the second roller brush 27 connected to the third gear 26; at the same time, the servo motor 29 drives the semicircular brush 31 to reciprocate along the following motion trajectory through the belt 30: when the third slide rail 41 and the track 42 completely overlap, the semicircular brush 31 is in the initial position; the servo motor 29 drives the semicircular brush 31 to rotate 90° in the clockwise direction, and then, the servo motor 29 drives the semicircular brush 31 to rotate 90° in the counterclockwise direction and return to the initial position, and then, the servo motor 29 drives the semicircular brush 31 to rotate 90° in the counterclockwise direction, and then, the servo motor 29 drives the semicircular brush 31 to rotate 90° in the clockwise direction and return to the initial position. At this time, the first roller brush 25, the second roller brush 27 and the semicircular brush 31 clean the dust on the heating furnace base.

[0030] After the dust and dirt are cleaned, the staff turns off the second motor 22 and the servo motor 29, and then the first roller brush 25, the second roller brush 27 and the semicircular brush 31 stop rotating; then, the staff turns off the first motor 11 and retracts the piston of the cylinder 17, thereby driving the second receiving plate 18 and the third receiving plate 19 fastened thereto to retract, and at the same time, all components connected to the third receiving plate 19 retract to avoid safety hazards.

[0031] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
