Description
Technical Field
The utility model relates to a boat sling device energy storage buffer system.
Background
The high-speed work boat retracting device is a special device which is arranged on a ship deck and used for retracting and lowering a high-speed work boat. When the boat is descended, the passengers sit in the boat (the weight of the boat and the passengers is about 30KN when the passengers are full), the luffing cylinder of the retraction device is rotated out through the control valve, and then the working boat connected with the steel wire rope lifting hook is quickly lowered to the water surface through the winch. At the moment, the steel wire rope winding and unwinding speed is required to reach 48M/MIN. When the winch is suddenly stopped in a fully-loaded high-speed retraction state, a large impact force acts on a steel wire rope of the winch due to inertia, so that certain danger is brought to passengers on a boat, meanwhile, the steel wire rope and a brake of the winch generate large impact load, and the reliability and the service life of equipment are reduced. In order to reduce impact load, a hydraulic buffer system consisting of a hydraulic cylinder and an energy accumulator is mostly installed on a high-speed work boat retraction device at present. The rod cavity and the rodless cavity of the hydraulic oil cylinder of the system are communicated through the throttling hole, and the effective working area during the buffering action is the difference between the areas of the rod cavity and the rodless cavity. If the tonnage of the retracting device is large, the effective working area of the buffer oil cylinder is large in order to adapt to the change of the buffer force, so that the volume of the oil cylinder is large.

Detailed Description
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
As shown in fig. 1-2, the energy storage buffer system of the boat lifting device comprises a winch 1, a steel wire rope 2, a work boat 3, a buffer oil cylinder 4, a fixed pulley 5, a movable pulley 6, a stop valve i 7, a one-way valve 8, a stop valve i 9, a pressure gauge 10, an energy accumulator 11, a guide sleeve 12, a silencer 13, a cylinder 14, a piston rod 15, a piston 16 and an oil pipe 17.
The winch 1 is fixed on a seat frame of the retraction device, one end of a steel wire rope 2 is wound on a winding drum of the winch 1, and the other end of the steel wire rope is connected with a lifting hook of the working boat 3 through a fixed pulley 5 and a movable pulley 6. The base of the buffer oil cylinder 4 is fixed on the seat frame, and the ear ring of the piston rod 15 is connected with the axle center of the movable pulley 6. Before the buffer system is used, hydraulic oil with certain pressure is filled into the buffer oil cylinder 4 and the energy accumulator 11 in advance through the stop valve I7, and the magnitude of the filling pressure is observed through the pressure gauge 10. When the pressure of the oil filling liquid in the buffer oil cylinder 4 is too high, redundant oil can be discharged to an oil tank through the stop valve II 7. The check valve 8 is used for buffering the pressure of the system energy accumulator 11 and preventing the oil in the energy accumulator 11 from flowing reversely when the stop valve 7 is opened.
The working process of the buffer system is as follows: when the winch 1 is stably wound and unwound, the piston rod 15 of the buffer oil cylinder 4 is completely extended out under the action of pressure oil stored in the energy accumulator 11 due to no extra impact load, and the length of the steel wire rope 2 is not changed in the winding and unwinding process.
When the winch 1 is suddenly stopped at high speed in a full load state, a large impact force acts on the steel wire rope 2 of the winch 1 due to inertia, and the impact force is rapidly transmitted to the piston rod 15 of the buffer oil cylinder 4 through the movable pulley 6 connected with the steel wire rope 2, so that the piston rod 15 of the oil cylinder is forced to retract, and oil in a rodless cavity of the oil cylinder is compressed to the energy accumulator 11. Because the nitrogen in the accumulator 11 has compressibility, the energy generated sharply can be smoothly absorbed, and the aim of buffering and damping is achieved.
The accumulator 11 is bolted to the cylinder 14. The energy accumulator 11 is connected with the rodless cavity of the oil cylinder by an oil pipe 17, the oil charging and discharging of the energy accumulator 11 are carried out through the oil pipe 17, and the effective working area of the buffer oil cylinder 4 is the area of the rodless cavity. The cylinder barrel 14 is provided with a damping hole which is used for limiting the oil flow of the energy accumulator entering and exiting the rodless cavity of the buffer oil cylinder and ensuring the stable motion of a piston rod of the oil cylinder. The movable pulley seat is connected with a square flange at the end part of the piston rod 15. When the piston 16 and the piston rod 15 move along the guide sleeve 12 during the work of the buffer system, the volume of a cylinder cavity is changed continuously, the silencer 13 can realize 'breathing', external dirt is prevented from entering the inside of the oil cylinder, and abnormal sound of air flow entering and exiting the cylinder barrel can be eliminated.
The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
