This invention discloses an intelligent safety repair system and method for extra-large mine skip drum sides, belonging to the field of mine hoisting equipment maintenance technology. The intelligent safety repair system includes: an identification system equipped with an image recognition unit for real-time monitoring of the skip's shape; a control system including computer software and a PLC control system; and a skip shape adjustment system including a sensor system, a power system, and an actuator. The sensor system includes contact sensors, displacement sensors, and contour dimension sensors, while the actuator includes a hydraulic system and actuators. The intelligent safety repair system for extra-large mine skip drum sides provided by this invention offers high safety, avoiding manual entry into the skip for repair work. This eliminates the safety risks of falls from heights, material impact injuries, and accidental gate opening faced by workers entering dangerous areas, ensuring the personal safety of personnel and extending the skip's service life.

This invention belongs to the field of epitaxial growth technology, specifically an epitaxial furnace gas inlet device, including a furnace body. An inlet cylinder is connected to one side of the furnace body. A rotating ring is sleeved on the surface of the inlet cylinder. Multiple first magnetic blocks are uniformly fixed to the annular circumference of the rotating ring, and a toothed ring is fixed to the side of the rotating ring. This epitaxial furnace gas inlet device, by incorporating the toothed ring, allows the first magnetic blocks on the rotating ring surface to rotate synchronously when the toothed ring rotates during use. The first magnetic blocks and second magnetic blocks are magnetically attracted, and the second magnetic blocks, under the influence of the magnetic force, drive a rotating plate to rotate synchronously. The rotating plate drives the rotating cylinder to rotate, which in turn drives a stirring rod to rotate. The stirring rod mixes the process gas inside the inlet cylinder during rotation. The entire process does not require the output end of a drive motor to be inserted into the inlet cylinder, avoiding frictional heat generation that accelerates the aging of the sealing gasket, thus promoting long-term use and achieving further optimization of the existing inlet container stirring structure.
