Regarding the problems of stable operation,fast operation,good synchronization,and small dislocation of the closing door body of the 34 m gate of the Longxikou shiplock during the opening and closing process,this paper deeply analyzes the changing characteristics of the running resistance torque,and introduces the model and arrangement of hoist in detail.From the aspects of equipment and civil engineering,the two arrangement methods of inclined connection and vertical connection between the piston rod of hoist and the door body when the miter gate is fully open are compared,and the lock with a width of less than or equal to 16 m of the miter gate is suitable for oblique connection,and the vertical connection arrangement for the lock with the width of the miter gate greater than 16 m.The design characteristics of hoist and hydraulic control are introduced in detail.Based on the synchronous redundancy strategy,the design of hydraulic gate hoist is carried out.To realize the efficient and safe synchronization of the miter gate,two sets of displacement sensors are set up for mutual backup and mutual calibration.Through the trial operation of the Longxikou shiplock,the results are verified,and the design arrangement,selection and synchronous redundancy strategy of the hoist are reasonable and feasible.
