As shown in fig. 1-3, a multiple-degree-of-freedom hydraulic marine elevator shaft damping and vibration-damping device according to an exemplary embodiment is used for damping vibration of an elevator shaft and an elevator on a deck of a ship, and includes: the elevator comprises an elevator body 1, a connecting guide rail 2, an elevator shaft 3 and a hydraulic damper 4;
elevator main part 1 slidable mounting is in the inside wall of connecting guide rail 2, and connects the outside wall of guide rail 2 and the inside wall welding of elevartor shaft 3, every outside wall of elevartor shaft 3 all is provided with a plurality of fluid pressure type attenuator 4, and fluid pressure type attenuator 4 is total eight, and fluid pressure type attenuator 4 is used for connecting deck and elevartor shaft 3, can reduce the vibration range of elevartor shaft 3 like this. As for 2 hydraulic dampers 4 in each direction, since this can exert a damping effect in any direction on the XY plane;
the hydraulic damper 4 comprises a piston head 41, one end of the piston head 41 is connected with a gasket 5, the gasket 5 enables the connection between the elevator shaft 3 and the hydraulic damper 4 to be more stable, a hydraulic oil cylinder 42 is inserted into the other end of the piston head 41, the inner cavity of the hydraulic oil cylinder 42 is provided with hydraulic oil, one end of a first connecting pipe 43 communicated with the hydraulic oil cylinder 42 is inserted into the top of the hydraulic oil cylinder 42, an oil reservoir 44 is inserted into the other end of the first connecting pipe 43, the upper end of the inner cavity of the oil reservoir 44 is filled with inert gas, the middle part of the first connecting pipe 43 is provided with a safety valve 45, one end of a second connecting pipe 46 communicated with the hydraulic oil cylinder 42 is inserted into the left side wall of the hydraulic oil cylinder 42, the other end of the second connecting pipe 46 is inserted into the bottom of the oil reservoir 44, the middle end of;
when the deck of the ship body is close to the elevator shaft 3, as shown in fig. 2, namely the piston head 4 moves leftwards, at this time, the piston head 41 moves leftwards in the inner cavity of the hydraulic oil cylinder 42, so that the pressure of hydraulic oil in the hydraulic oil cylinder 42 is increased, the hydraulic oil cannot flow to the oil reservoir through the second connecting pipe 46 due to the action of the one-way 47, at this time, the safety valve 45 cannot be opened, because the hydraulic oil can be pressed from the hydraulic oil cylinder 42 to the oil reservoir 44 only when the pressure is greater than that of the safety valve 45, the safety valve 45 plays an explosion-proof role, namely, the safety valve 45 is in a closed state at ordinary times, a reaction force (a rightward thrust force) can be generated by the pressure of the safety;
when the deck of the ship body is far away from the elevator shaft 3, as shown in fig. 2, namely the piston head 4 moves to the right, the pressure of hydraulic oil in the hydraulic oil cylinder is reduced due to the action of the one-way valve, the hydraulic oil flows to the hydraulic cylinder from the oil reservoir through the thin pipe and the one-way valve, the working principle of the hydraulic oil cylinder is the same as the resistance generated by liquid pumping of the injector, and therefore, the hydraulic oil cylinder can provide reverse resistance.
The hydraulic damper shown in fig. 2 operates as above, but the corresponding hydraulic damper 4 operates in the same state as the hydraulic damper 4, but in the opposite state, the damper 4 on the same side operates in the same state as the hydraulic damper 4, and the dampers 4 on different axes operate in the same state as the hydraulic damper 4.

A slight misalignment can occur due to the out of sync of the deck and hoistway 3 movements. That is, the X-direction damper can also move a little in the Y-direction. And this movement causes new noise problems. For example, when the piston head 41 of the hydraulic damper 4 is movable in the vertical Y direction, if the distance lssin θ is to be moved, the hydraulic oil is compressed by Δ L (1-cos θ), when the hydraulic damper 4 is moved, the first connecting steel sheet 61 is driven to rotate at the hinge joint of the first connecting steel sheet 61 and the second connecting steel sheet 62, the hydraulic damper 4 is moved downward, the second connecting steel sheet 62 is tightly attached to both ends of the elevator shaft 3, so that the elevator shaft 3 is clamped and cannot slide, and thus the structure can absorb the vertical movement and provide an indirect resistance when the hydraulic oil is compressed, the position limiting device 6 is welded to the side of the outer side wall of the hydraulic cylinder 42 close to the piston head 41, and the position limiting device 6 comprises the first connecting steel sheet 61, the second connecting steel sheet 62, and the position limiting device 6 is welded to the side of the piston head 41, One end of the first connecting steel sheet 61 is welded with the hydraulic oil cylinder 42, the other end of the first connecting steel sheet 61 is hinged with one end of the second connecting steel sheet 62 through the hinge bolt 63, and the other end of the second connecting steel sheet 62 is in threaded connection with the deck.
Specifically, in order to provide the same structural principle as the syringe to form the damper, the cross-sectional area of the second connection pipe 46 is smaller than that of the piston head 41.
Specifically, in order to provide good tightness for the hydraulic cylinder 42, the piston head 41 is a cylinder, and the rubber ring 7 is sleeved on the outer side wall of the piston head 41.
Specifically, the second connection pipe 46 and the first connection pipe 43 both communicate with the oil reservoir 44.
With regard to the apparatus in the above-described embodiment, the specific manner in which each module performs the operation has been described in detail in the embodiment related to the method, and will not be elaborated here.
The working principle is as follows: when the deck of the ship body is close to the elevator shaft 3, as shown in fig. 2, namely the gasket 5 and the piston head 4 move leftwards, at this time, the piston head 41 moves leftwards in the cavity of the hydraulic oil cylinder 42, so that the pressure of hydraulic oil in the hydraulic oil cylinder 42 is increased, the hydraulic oil cannot flow to the oil reservoir through the second connecting pipe 46 due to the action of the one-way 47, at this time, the safety valve 45 cannot be opened, because the hydraulic oil can be pressed from the hydraulic oil cylinder 42 to the oil reservoir 44 only when the pressure of the safety valve 45 is greater than the pressure of the safety valve 45, the safety valve 45 has an explosion-proof function, namely, the safety valve is in a closed state at ordinary times, a reaction force (a rightward thrust force) can be generated by;
