Abstract: A semi-automatic adjustment device for suppressing tension fluctuations during a rolling process of an ultra-thin strip includes a semi-automatic tension regulator, a semi-automatic tuned mass damper of variable stiffness and damping, a coiler, a tension roller and a twenty-high roller system. The semi-automatic tension regulator is disposed between the coiler and the tension roller, the semi-automatic tuned mass damper of variable stiffness and damping is disposed between the tension roller and the twenty-high roller system. The semi-automatic adjustment device can be used to reduce a short-time fluctuation impact of tension during startup and shutdown of a twenty-high roll mill when the twenty-high rolling mill rolls an ultra-thin strip, improve system stability, absorb the continuous micro disturbances generated during the rolling process of the twenty-high roll mill, and achieve flexible and stable adjustment of tension during the rolling process.

Abstract: A device for continuously applying a transverse tension in an annealing process of an ultra-thin strip, including an unfolding and receiving mechanism for unwinding and winding the strip and an orthopedic mechanism for correcting the strip including an annealing furnace, and two orthopedic assemblies fixedly arranged inside the annealing furnace; the two orthopedic assemblies are symmetrically arranged on both sides of the strip, are parallel to an advancing direction of the strip and correspond to side edges of the strip, and include annular guide rails; each annular guide rail is fixedly connected with the annealing furnace and is slidably connected with an orthopedic part; the orthopedic part corresponds to each side edge of the strip, and each annular guide rail is internally provided with a driving part; the driving part is in transmission connection with the orthopedic part, and the orthopedic part is communicated with an air source part.

Abstract: The invention relates to an emergency support robot for polar UAVs, belonging to the technical field of emergency support robots for polar UAVs. The technical problem to be solved is to improve the structure of the existing emergency support robots for polar UAVs. The technical scheme adopted is as follows: the robot is of a car body structure; a support table is arranged on the upper side of the chassis of the car body; a traveling mechanism is arranged on both sides of the chassis of the car body; the two sides of the support table are hinged with a pair of casings through hinged buckles and push rods; the casings are also provided with a wind power plant; the support table is provided with a launching guide rail.

Abstract: A plate and strip rolling process oriented efficient and stable current applying manipulator is provided, which aims to effectively avoid potential safety hazards caused integral electrifying of the rack during normal current applying, can improve the defects that current loss is caused by a normal current applying way and the service life of the roller is shortened, and the difficulty in applying pulse current to plate strips while rolling plate strips with limited length dimensions at a higher temperature, and can realize stable loading of pulse current with limited dimension, and effectively act pulse current within a rolling region.
