Shock absorption protection device for ship berthing

Abstract

The utility model belongs to the technical field of ship protection, and particularly relates to a damping protection device for ship docking, which comprises a mounting plate, and a damping component is arranged on the mounting plate. As the length of the extrusion column on the first carrier plate is larger than that of the extrusion column on the second carrier plate, the length of the extrusion column on the third carrier plate and the length of the extrusion column on the fourth carrier plate, the extrusion column on the first carrier plate firstly extrudes the contact surface of the wharf, and then the extrusion column on the second carrier plate extrudes the contact surface of the wharf. Along with collision to the contact surface of the wharf, an extrusion column on the third carrier plate extrudes the contact surface of the wharf, and finally an extrusion column on the fourth carrier plate extrudes the contact surface of the wharf, so that the damping assembly has a buffering process when the damping assembly collides with the contact surface of the wharf. Compared with the prior art, the impact force is dispersed, and the damping effect is improved.

Description

Technical Field

[0001] The utility model relates to the technical field of ship protection, and more particularly to a shock-absorbing and protective device for docking ships. Background Art

[0002] In the field of marine engineering, vibration mitigation and protection during docking is a long-standing technical challenge. Traditionally, during docking, particularly in strong winds and waves or due to improper operation, collisions between the hull and the dock, buoys, or other docking facilities are common. To prevent these collisions, protective devices are installed.

[0003] For example, the authorization announcement number CN219687581U discloses a shock-absorbing assembly for ship berthing, including a mounting plate, which includes a first plate body, a second plate body and a tube body component placed between the first plate body and the second plate body. One end of the extrusion component is squeezed against the dock contact surface, and the extrusion component moves into the cavity so that the other end of the extrusion component passes through the movable station and is squeezed into contact with the elastic component. Through the tube fitting in the extrusion component and the connecting piece in the elastic component, when the extrusion component squeezes the elastic component, a rebound force is generated to push the extrusion component outward, thereby reducing the deformation of the shock-absorbing component and increasing the impact resistance of the dock contact surface.

[0004] In the above description, when the contact surface of the dock is hit, the impact force directly contacts the extrusion component, and all the impact force will be blocked by the extrusion component. Since the extrusion components are on the same horizontal line, there is no buffering process for the extrusion components when they are subjected to the impact force, and the impact force cannot be dispersed outward, thereby reducing the shock absorption effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a shock-absorbing and protective device for docking ships that disperses impact force and improves shock absorption effect.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A shock-absorbing protective device for docking a ship comprises a mounting plate, a shock-absorbing component is provided on the mounting plate, and the shock-absorbing component is connected to the mounting plate.

[0008] The shock absorbing assembly includes a first carrier plate, a second carrier plate, a third carrier plate and a fourth carrier plate.

[0009] The first carrier board, the second carrier board, the third carrier board and the fourth carrier board each have two,

[0010] The first carrier plate, the second carrier plate, the third carrier plate and the fourth carrier plate are all distributed horizontally.

[0011] The two second carrier plates, the two third carrier plates and the two fourth carrier plates are all placed between the two first carrier plates.

[0012] Two third carrier plates and two fourth carrier plates are placed between the two second carrier plates.

[0013] The two fourth carrier plates are placed between the two third carrier plates.

[0014] The first carrier plate, the second carrier plate, the third carrier plate and the fourth carrier plate are all provided with an extrusion column and a fixing seat, and the extrusion block is placed above the fixing seat and is movably connected to the fixing seat.

[0015] The length of the extrusion column on the first carrier plate is greater than that on the second carrier plate, greater than that on the third carrier plate, and greater than that on the fourth carrier plate.

[0016] The utility model is further configured as follows: a movable column is provided on the extrusion column, a connecting groove for the movable column to extend into is opened on the fixed seat, an elastic ball is provided in the connecting groove, the outer wall of the elastic ball is connected to the inner wall of the connecting groove, and the two ends of the movable column are respectively connected to the bottom surface of the extrusion column and the outer wall of the elastic ball.

[0017] The utility model is further configured as follows: a first buffer cavity is provided in the elastic ball, a rebound strip is provided in the first buffer cavity, and two ends of the rebound strip are respectively connected to the inner wall of the first buffer cavity.

[0018] The utility model is further configured as follows: a second buffer cavity is provided in the extrusion column, and a third buffer cavity is provided in the movable column.

[0019] By adopting the above technical solution, the beneficial effects of the utility model are:

[0020] When a ship docks, it will collide with the dock contact surface. Since the length of the extrusion column on the first carrier plate is greater than that of the extrusion column on the second carrier plate, greater than that of the extrusion column on the third carrier plate, and greater than that of the extrusion column on the fourth carrier plate, and the two first carrier plates, the two second carrier plates, the two third carrier plates and the two fourth carrier plates are U-shaped, the extrusion column on the first carrier plate first squeezes the dock contact surface, and then the extrusion column on the second carrier plate squeezes the dock contact surface. With the collision with the dock contact surface, the extrusion column on the third carrier plate squeezes the dock contact surface, and finally the extrusion column on the fourth carrier plate squeezes the dock contact surface. When the shock-absorbing component collides with the dock contact surface, the shock-absorbing component has a buffering process, thereby effectively dispersing the impact force and improving the shock absorption effect.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] like Figures 1 to 2 As shown, the shock-absorbing protection device for docking a ship includes a mounting plate 1, on which a shock-absorbing assembly is mounted. The shock-absorbing assembly is welded and fixed to the mounting plate 1, and screws are squeezed through the contact surface between the mounting plate 1 and the ship to fix the ship and the shock-absorbing assembly.

[0028] The shock-absorbing assembly includes a first carrier plate 2, a second carrier plate 3, a third carrier plate 4 and a fourth carrier plate 5. There are two first carrier plates 2, two second carrier plates 3, third carrier plates 4 and fourth carrier plates 5. The first carrier plates 2, the second carrier plates 3, the third carrier plates 4 and the fourth carrier plates 5 are all horizontally distributed. The two second carrier plates 3, the two third carrier plates 4 and the two fourth carrier plates 5 are placed between the two first carrier plates 2, the two third carrier plates 4 and the two fourth carrier plates 5 are placed between the two second carrier plates 3, and the two fourth carrier plates 5 are placed between the two third carrier plates 4. Through the two first carrier plates 2, the two second carrier plates 3, the two third carrier plates 4 and the two fourth carrier plates 5, a total of eight tubes are used for better shock absorption.

[0029] Extrusion columns 6 and fixed seats 7 are installed on the first carrier plate 2, the second carrier plate 3, the third carrier plate 4 and the fourth carrier plate 5. The extrusion block is placed above the fixed seat 7 and is movably connected to the fixed seat 7. The outer wall of the extrusion column 6 is an arc surface. The length of the extrusion column 6 on the first carrier plate 2 is greater than that of the extrusion column 6 on the second carrier plate 3, greater than that of the extrusion column 6 on the third carrier plate 4, and greater than that of the extrusion column 6 on the fourth carrier plate 5.

[0030] The first first carrier plate 2, the first second carrier plate 3, the first third carrier plate 4 and the first fourth carrier plate 5 are in a downhill shape, and the second first carrier plate 2, the second second carrier plate 3, the second third carrier plate 4 and the second fourth carrier plate 5 are also in a downhill shape. The two downhill slopes form a U-shape, so that the two first carrier plates 2, the two second carrier plates 3, the two third carrier plates 4 and the two fourth carrier plates 5 are in a U-shape.

[0031] A movable column 8 is installed on the extrusion column 6, and a connecting groove for the movable column 8 to extend into is opened on the fixed seat 7. An elastic ball 9 is installed in the connecting groove. The outer wall of the elastic ball 9 is connected to the inner wall of the connecting groove. The two ends of the movable column 8 are respectively connected to the bottom surface of the extrusion column 6 and the outer wall of the elastic ball 9.

[0032] When the squeezing column 6 on the first carrier plate 2 squeezes the dock contact surface again, the movable column 8 on the first carrier plate 2 squeezes the elastic ball 9 on the first carrier plate 2 in the connecting groove, so that the movable column 8 on the first carrier plate 2 can extend into the connecting groove and extend into the squeezing column 6 on the second carrier plate 3 to squeeze the dock contact surface. The movable column 8 on the second carrier plate 3 squeezes the elastic ball 9 on the second carrier plate 3 in the connecting groove, and the movable column 8 on the second carrier plate 3 can extend into the connecting groove.

[0033] The extrusion column 6 extending into the third carrier plate 4 is pressed against the dock contact surface, and the movable column 8 on the third carrier plate 4 squeezes the elastic ball 9 on the third carrier plate 4 in the connecting groove. The movable column 8 on the third carrier plate 4 can be extended into the connecting groove and extended into the fourth carrier plate 5 to be pressed against the dock contact surface, and the movable column 8 on the fourth carrier plate 5 squeezes the elastic ball 9 on the fourth carrier plate 5 in the connecting groove, thus forming a complete process of squeezing and damping the dock contact surface.

[0034] The elastic ball 9 has a first buffer cavity 10, and a rebound strip 11 is installed in the first buffer cavity 10. The two ends of the rebound strip 11 are respectively connected to the inner wall of the first buffer cavity 10. When the elastic ball 9 is squeezed, an elastic space is formed between the rebound strip 11 and the first buffer cavity 10, which further achieves a shock-absorbing effect.

[0035] A second buffer cavity 12 is provided in the extrusion column 6 , and a third buffer cavity 13 is provided in the movable column 8 . During the extrusion process of the extrusion column 6 , both the extrusion column 6 and the movable column 8 have extrusion space.

[0036] Working principle: When a ship docks, it will collide with the dock contact surface. Since the length of the extrusion column 6 on the first carrier plate 2 is greater than the extrusion column 6 on the second carrier plate 3, the length of the extrusion column 6 on the third carrier plate 4, and the length of the extrusion column 6 on the fourth carrier plate 5, and the two first carrier plates 2, the two second carrier plates 3, the two third carrier plates 4 and the two fourth carrier plates 5 are U-shaped, the extrusion column 6 on the first carrier plate 2 first squeezes the dock contact surface, and then the extrusion column 6 on the second carrier plate 3 squeezes the dock contact surface. With the collision with the dock contact surface, the extrusion column 6 on the third carrier plate 4 squeezes the dock contact surface again, and finally the extrusion column 6 on the fourth carrier plate 5 squeezes the dock contact surface, so that when the shock absorber assembly collides with the dock contact surface, the shock absorber assembly has a buffering process, thereby effectively dispersing the impact force and improving the shock absorption effect.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
