3results about How to "Speed synchronization" patented technology

This disclosure provides a control method and control device for a lifting system, belonging to the field of offshore platform lifting technology. The control method includes: determining the actual speed and load of the main motor and each slave motor on each leg, wherein the main motor is any one of a plurality of variable frequency motors in the leg, and the slave motors are all the variable frequency motors except the main motor; for any leg, adjusting the actual speed of each slave motor according to the actual speed of the main motor and the actual speed of each slave motor, as well as the load of the main motor and the load of each slave motor, so that the actual speed of the slave motor is synchronized with the actual speed of the main motor, and the load of the slave motor is synchronized with the load of the main motor.

The utility model relates to the technical field of plate straightening, and provides a plate straightening mechanism of cable clamping plate shearing machine, which comprises a machine body, the bottom of the machine body is fixedly connected with a supporting foot pad, the side of the machine body is fixedly connected with a feeding plate, the side of the machine body is fixedly connected with a discharging box, the inner side of the machine body is fixedly connected with a vertical plate, the side of the vertical plate is rotatably connected with an upper roller, the side of the vertical plate is rotatably connected with a lower roller, and the inside of the machine body is provided with a correction mechanism. The utility model further comprises a correction mechanism and a fixed-length cutting mechanism, the mutual cooperation of internal components of the correction mechanism guarantees straightening precision, avoids plate deviation or damage, power transmission is stable, and plate straightening quality and efficiency are improved, laying a good foundation for subsequent processing. Through the above technical scheme, the technical problem that the correction effect is poor and cutting cannot reach a certain precision in the related art is solved.

The present application relates to the technical field of gypsum board forming, in particular to a kind of automatic forming equipment of gypsum board and method thereof, the present application includes base, forming conveyor belt, upper cover paper and lower cover paper, the base top is symmetrically provided with driving pressure wheel and driven feed wheel, upper cover paper and lower cover paper all pass between driving pressure wheel and driven feed wheel;The main shaft of the forming conveyor belt is the only power source of whole equipment.The present application uses main shaft as the only power source, simultaneously drives forming conveyor belt, same speed feeding mechanism, self-adapting slurry laying opening adjusting mechanism and bubble-punching type defoaming mechanism action, without additional independent power source, not only simplify the equipment structure, reduce manufacturing cost and energy consumption, also ensure that the speed of each mechanism is completely synchronous with main shaft, avoid cover paper stretching, tearing, misplacement, slurry overflow, core lack and other forming defects from the root, improve equipment running stability.
