Description

[0002] The rotary kiln equipment is used for the magnetization roasting of lean iron ore in steel plants in the metallurgical industry. The kiln lining is a refractory material lined on the inner surface of the rotary kiln cylinder. Its refractoriness is greater than 1580 degrees Celsius, and it can resist a series of physical and chemical actions in the working space. The role of the kiln lining in the rotary kiln is to protect the cylinder body from high-temperature damage, play a heat-insulating role, and reduce heat dissipation loss. Usually, refractory bricks are used. The maintenance of the rotary kiln lining mainly includes steps such as inspection, removal, repair, and replacement. Before maintenance, it is necessary to ensure that the temperature inside the rotary kiln is reduced to a safe level so that personnel can enter to check the damage of the refractory bricks.

[0021] In this embodiment: Move the mounting seat 1 to the inside of the rotary kiln. Through the cooperation of the parts in the positioning mechanism 6, position the mounting seat 1 inside the rotary kiln so that the mounting seat 1 and the rotary kiln are in the same axial position. At this time, the rotating arm 2 is in a downward vertical state. At this time, the first motor 504 can be started. The operation of the first motor 504 drives the first threaded rod 505 to rotate. The rotation of the first threaded rod 505 drives the connecting plate 506 to displace. The displacement of the connecting plate 506 drives the telescopic arm 503 to displace. The displacement of the telescopic arm 503 drives the chiseling bit 4 into the position after the annular brick lining is removed. Start the drilling machine 3 to drive the chiseling bit 4 to rotate. At this time, start the second motor 509. The operation of the second motor 509 drives the second threaded rod 510 to rotate. The rotation of the second threaded rod 510 drives the movable frame 508 to reciprocate in the movable groove 507. The displacement of the movable frame 508 drives the chiseling bit 4 to move horizontally. Whenever the displacement of the movable frame 508 contacts the extrusion rod 511, the movable frame 508 pushes the extrusion rod 511 to displace. The displacement of the extrusion rod 511 pushes the pushing block 512 to displace, stretching the first spring 513. The displacement of the pushing block 512 pushes the pushing rod 514 to displace. The displacement of the pushing rod 514 drives the mounting plate 515 to displace, squeezing the second spring 516. The displacement of the mounting plate 515 drives the displacement seat 517 to displace. The displacement of the displacement seat 517 drives the ratchet wheel 518 to rotate through the toothed plate 522. The rotation of the ratchet wheel 518 drives the worm 519 to rotate. The rotation of the worm 519 drives the rotating arm 2 to rotate relative to the worm gear 502, thereby driving the rotating arm 2 to rotate a small distance. After that, the chiseling bit 4 continues to move horizontally. The movable frame 508 separates from the extrusion rod 511. The pushing block 512 is reset under the elastic force of the first spring 513. At the same time, the pushing rod 514, the mounting plate 515 and the displacement seat 517 are displaced and reset under the elastic force of the second spring 516. At this time, the clamping block 520 is engaged with the ratchet wheel 518 under the elastic force of the third spring 521, thereby preventing the ratchet wheel 518 from rotating in the reverse direction. After repeating many times, the position after the annular brick lining is removed is cleaned up.

[0022] Please refer specifically to Figures 8 to 9, the positioning mechanism 6 includes two positioning frames 601.

A third motor 608 is installed at one end of the mounting base 1 away from the fixed shaft 501. The output end of the third motor 608 is connected to a third threaded rod 607. A rotating disc 606 is fixedly connected to the outer wall of the third threaded rod 607. A bevel gear 605 is rotatably connected to the outer wall of the rotating disc 606 inside the mounting base 1. One end of the bevel gear 605 is fixedly connected to a fourth threaded rod 604. The fourth threaded rod 604 extends into the inside of the movable rod 602. A displacement plate 609 is slidably connected inside the mounting base 1. The third threaded rod 607 passes through the displacement plate 609. A positioning plate 610 extending out of the mounting base 1 is fixedly connected to the outer wall of the displacement plate 609.

[0023] In this embodiment: When positioning the position of the mounting base 1, start the third motor 608. The operation of the third motor 608 drives the third threaded rod 607 to rotate.
