2results about How to "Avoid breaking accidents" patented technology

This invention relates to a sintering machine trolley elastic slide travel detection and reset system and method, belonging to the field of metallurgical technology. It includes a sintering machine trolley, with its base fixed to an elastic slide. The elastic slide is connected to a sealing oil plate via a support spring. A travel detection mechanism is installed above the sealing oil plate, electrically connected to a controller. The controller is electrically connected to a main control display and a reset actuator. The travel detection mechanism detects the reset status of the sealing oil plate and transmits the data to the controller. If the sealing oil plate fails to reset normally, the controller controls the actuator to force the sealing oil plate to reset, and transmits the data to the main control display in real time. This invention can automatically detect the working status of the elastic slide and accurately reset abnormal elastic slides, effectively avoiding accidents caused by fixed slide breakage due to elastic slide abnormalities. This greatly improves the stability of the sintering machine trolley operation and further ensures production efficiency.

This invention discloses a lightweight modular FRP lifting device and its control method. The lifting device includes an expandable lifting frame body assembled from several basic structural units. Each basic structural unit adopts a steel-FRP composite structure, with an inner layer of I-beams and an outer layer of FRP fiber-reinforced fabric. A multi-degree-of-freedom adjustment mechanism is installed at the bottom of each basic structural unit. This mechanism includes a linear module and a winch. The linear module is set and fixed along the length of the basic structural unit, and the winch is fixed below the slider of the linear module. The winch's wire rope is connected to the lifting point of the building module to be lifted. The control method uses center-of-gravity calculation and a PID algorithm for real-time feedback control. This invention effectively solves the problems of heavy weight, difficult balance adjustment, and low level of intelligence in traditional lifting devices, achieving automatic leveling and precise positioning of the lifted building module, significantly improving lifting efficiency and safety.
