Description

Technical Field

[0001] This utility model relates to the field of pneumatic furnace building machines, and in particular to a pneumatic furnace building machine that facilitates cylinder position adjustment. Background Technology

[0002] Pneumatic furnace lining machines are mainly used in the metallurgical and casting industries for tamping and compacting furnace lining materials. They use compressed air to drive cylinders, which in turn drive tamping heads to perform high-frequency impact compaction of the refractory materials in the furnace chamber. This ensures that the furnace lining structure is uniform and dense, thereby improving the service life and thermal efficiency of industrial furnaces. Compared with traditional manual tamping, pneumatic furnace lining machines have advantages such as high operating efficiency, low labor intensity, and stable compaction quality. They are an indispensable key piece of equipment in modern metallurgical and casting production lines.

[0003] Existing technology, patent CN214009950U, discloses a pneumatic furnace-building machine that facilitates cylinder position adjustment. The machine includes a base, which is disc-shaped and horizontally positioned. Several mounting seats are radially slidably connected to the base, and these mounting seats are rotationally symmetrical about the center of the base. A cylinder is connected to each mounting seat. An adjusting seat, also disc-shaped and coaxial with the base, is rotatably connected to the upper side of the base. The adjusting seat has an arc-shaped groove, the distance from which to the center of the groove gradually increases along its arc. The two ends of the arc-shaped groove form an angle with the line connecting them to the center of the adjusting seat. Several arc-shaped grooves are rotationally symmetrically distributed about the center of the adjusting seat, and each groove corresponds to a mounting seat. A sliding shaft is connected to the mounting seat, vertically positioned and passing through the arc-shaped groove. A drive assembly for rotating the adjusting seat is provided on the base. This application provides the advantage of facilitating cylinder position adjustment.

[0004] However, the above-mentioned patent has two significant technical defects in practical application: the patent only fixes the bidirectional ratchet by adjusting the locking rod to lock the adjusting seat. However, the pneumatic furnace building machine will generate a lot of vibration during operation. This single locking method is difficult to guarantee the stability of the overall device during operation, and the locking rod and the bidirectional ratchet are prone to loosening, affecting the quality of operation. In addition, the device uses a handwheel for adjustment, which not only increases the complexity of the overall structure, but also makes the operation cumbersome and the adjustment inconvenient, seriously affecting the work efficiency and equipment compactness.

[0005] To address the aforementioned problems, we have developed a pneumatic furnace-building machine that facilitates cylinder position adjustment. Utility Model Content

[0022] The adjustment mechanism includes an adjustment connecting plate 22, which is fixed to the outer wall of the main shaft 8. The adjustment connecting plate 22 and the locking plate 24 are at the same height, and the adjustment connecting plate 22 is located on the symmetrical center line of the two locking plates 24, which avoids structural deformation or loosening due to eccentric force and improves the overall coordination and stability of the structure.

The middle part is a hemispherical groove, and the two sides are set as quarter-spherical grooves, so that the ball head 233 can pass smoothly through the middle and be locked into the hemispherical groove.

[0023] The transmission mechanism includes a coupling positioning plate 10. The coupling positioning plate 10 is fixed to the outer wall of the main shaft 8.

[0026] In use, the worker first pulls the pull ring 265 at the second locking mechanism 28. The pull ring 265 drives the connecting rod 264 to move upward along the cylindrical groove. The connecting rod 264 drives the slide rod 262 to move upward synchronously. The slide rod 262 then drives the buckle 261 to move upward and disengage from the limit of the second locking clamp 27. At the same time, the worker turns the adjusting plate 22 counterclockwise. The adjusting plate 22 drives the main shaft 8 to rotate. The main shaft 8 drives the locking plate 24 to rotate counterclockwise synchronously. At this time, the special groove structure at the bottom of the adjusting plate 22 contacts the locking pin 23 and squeezes the ball head 233. The ball head 233 and the guide post 232 together squeeze the third spring 231. The third spring 231 is compressed, causing the ball head 233 and the guide post 232 to enter the cylindrical groove at the bottom of the arc groove. At this time, the locking plate 24 at the first locking clamp 25 slides along the inner wall of the annular groove. Since the first locking clamp 25 is set in a counterclockwise direction, the buckle 261 of the first locking mechanism 26 will slide and squeeze the fourth spring 263 as the first locking clamp 25 slides, causing the fourth spring 263 to be compressed. Each time it passes through a clamp, the fourth spring 263 recovers its deformation and then continues to be compressed, causing the fourth spring 263 to be periodically compressed. At the same time, the main shaft 8 synchronously drives the counterweight plate 21 and the coupling positioning plate 10 to rotate. The coupling positioning plate 10 drives several first rotating shafts 11 to rotate. Each first rotating shaft 11 drives its upper and lower two first connecting plates 12 to move in the long groove opened in the base 4, thereby driving the second rotating shaft 13 towards the center of the main shaft 8. The second rotating shaft 13 rotates, causing its two upper and lower arc-shaped protrusions 14 to move inward synchronously. Due to the restriction of the inner wall of the base 4 and the slider 15, the fixing plate 5 moves along the inner wall of the base 4 towards the center of the main shaft 8. The fixing plate 5 drives the cylinder 6 and the hammer 7 to move towards the main shaft 8 synchronously. During the sliding process of the slider 15 on the inner wall of the base 4, it squeezes the first spring 16. At the same time, when the coupling positioning plate 10 rotates, several second connecting plates 17 rotate accordingly. At this time, the guide rod 18 fixed to the second connecting plate 17 rotates accordingly and squeezes the second spring 181. The second spring 181 is compressed by force, and the guide rod 18 slides into the guide cylinder 19. After the cylinder 6 is adjusted to the required position, stop moving the adjusting connecting plate 22 and release the pull ring 265. Adjust the half of the bottom middle of the adjusting connecting plate 22. The spherical groove abuts against the ball head 233 at its current position, the third spring 231 returns to its original deformation, the guide column 232 and the ball head 233 limit the adjustment connecting plate 22, and the second locking mechanism 28 re-limits the second locking clamp 27. At this time, the worker transports the pneumatic furnace-building machine to the designated height via the chain 1 and sprocket 2, starts the cylinder 6, and the pneumatic furnace-building machine begins operation. After the operation is completed, the cylinder 6 is closed, and the worker pulls the pull ring 265 at the first locking mechanism 26. The pull ring 265 drives the connecting rod 264 and the sliding rod 262 to move upward, and the sliding rod 262 drives the buckle 261 to move upward, causing the buckle 261 to disengage from the limit of the first locking clamp 25. At this time, the worker turns the adjustment connecting plate 22 clockwise to reset it, and the two locking plates 24 rotate clockwise.The first locking clamp 25 and the second locking clamp 27 slide clockwise within the annular groove. At this time, the latch 261 of the second locking mechanism 28 moves with the second locking clamp 27, thereby pressing the latch 261 upwards, which in turn presses the fourth spring 263. When the adjusting connecting plate 22 returns to its initial position, the hemispherical groove at the center of its bottom abuts against the ball head 233. The first locking mechanism 26 and the second locking mechanism 28 respectively limit the first locking clamp 25 and the second locking clamp 27. Under the limitation of the first locking mechanism 26, the second locking mechanism 28, and the ball head 233, the adjusting connecting plate 22 and the two locking plates 24 are limited, thereby stably limiting the coupling positioning plate 10, ensuring the stability and safety of the pneumatic furnace-building machine during transportation after work is completed.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
