Other AbstractThe utility model discloses an antiswinging and oscillating stopping device. Thread screw oil cylinders are right and left symmetrically arranged under a crossbeam of a door-shaped frame collecting and releasing system. An outer transmission thread is arranged in the middle part of the piston rod of each thread screw oil cylinder, and is matched with an inner transmission thread of a piston. Both ends of the piston rod are separately supported by two sliding bearings arranged on a cylinder-barrel and a cylinder cover. The piston only moves back and forth without rotation under the action of two guiding rod. The shaft of a swinging frame and the shaft hole of the swinging frame are fixedly connected by flat keys. The shaft of the swinging frame and the shaft hole of a lifting lug are in sliding connection by a sliding bearing A and a sliding bearing B. When the collecting and releasing system is in operation, under the condition of oscillation of the swinging frame and interlocked equipment under the swinging frame by the movement of ships, the swinging torque of the swinging frame is transmitted to the piston of the thread screw oil cylinder by the swinging frame shaft and the piston rod (thread screw), and then the damping to swinging motion can be realized by the hydraulic system. The utility model has the advantages of compact structure, sensitive reaction, novel structure and reliable operation because of using the principle of screw thread transmission.
