Description

Technical Field

[0001] This utility model belongs to the field of ship berthing technology, specifically relating to a ship berthing buffer device. Background Technology

[0002] To address the problem of significant impact forces generated when ships dock in rough seas or due to improper maneuvering, potentially causing damage to the hull structure, existing technologies employ ship berthing buffers. These buffers utilize elastic materials or structures to absorb and disperse the impact forces during berthing, thereby protecting the hull structure from damage. However, existing ship berthing buffers still have some limitations in practical applications.

[0003] Existing buffer devices employ complex mechanical structures or hydraulic systems. For example, the buffer device for ship berthing disclosed in utility model patent CN221914557U uses springs, linkages, sliders, and other mechanisms to achieve a buffering effect, but this also increases the complexity and cost of the device. These complex structures not only increase the difficulty of installation and maintenance but may also lead to performance degradation due to malfunctions or wear, affecting the reliability and stability of the device. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a ship berthing buffer device that solves the problems that existing buffer devices are often complex in structure, high in cost, and inconvenient to install and maintain, which limits their widespread application.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ship berthing buffer device, comprising a mounting plate, a wooden pad attached to one side of the mounting plate, anchor bolts adapted to be inserted into the mounting plate and the wooden pad, limit sliders slidably mounted on the upper and lower sides of the mounting plate, the limit sliders being installed at the upper and lower ends of limit pins, the limit pins being inserted into the two ends of a buffer assembly, the buffer assembly comprising a plurality of mutually attached and stacked spring sheets, the two ends of the spring sheets facing the mounting plate having rolled ears adapted to be connected to the limit pins, connecting bolts slidably inserted into the spring sheets, the connecting bolts slidably passing through the mounting plate and threadedly connected to nuts, one end of the connecting bolts being connected to a pressure plate assembly, the pressure plate assembly abutting against the surface of the spring sheets facing away from the mounting plate.

[0006] The beneficial effects of this utility model are as follows: the device has a simple structure and low cost, and can be quickly assembled by bolts, multiple plates and leaf springs; the use of the buffer component in conjunction with the pressure plate component generates elastic deformation when the ship docks, effectively buffering and protecting the hull.

[0007] In order to effectively improve the stability of the buffer components;

[0008] As a further improvement to the above technical solution: the limiting pin is rotatably inserted into the lug.

[0009] The beneficial effects of this improvement are as follows: when the spring is deformed, the lug moves the limiting slider through the limiting pin. The limiting pin rotates relative to the lug, and the limiting slider moves on the outside of the mounting plate, ensuring the stability of the spring position and preventing one end of the spring from tilting up and causing the connecting bolt to be subjected to radial shear force.

[0010] To ensure the stability of the buffer components;

[0011] As a further improvement to the above technical solution: the limiting slider is an angle steel structure, and the inner wall of the limiting slider is slidably connected to two adjacent sides of the mounting plate.

[0012] The beneficial effect of this improvement is that the limiting slider acts as a limit, preventing the spring from warping up during deformation and expansion.

[0013] To ensure the stability of the buffer assembly installation;

[0014] As a further improvement to the above technical solution: the pressure plate assembly includes a rubber plate and a base plate, and the number of connecting bolts is multiple, with one end of each connecting bolt welded to the base plate.

[0015] The beneficial effects of this improvement are: the connecting bolts can stably connect multiple springs into one unit, and with the use of nuts, the buffer assembly can be firmly installed on the mounting plate as a whole.

[0016] To avoid direct collision between the substrate and the ship's hull, which would affect the substrate's lifespan;

[0017] As a further improvement to the above technical solution: the rubber sheet is bonded and fixed to the side of the substrate facing away from the buffer assembly.

[0018] The beneficial effects of this improvement are: the rubber sheet acts as an elastic buffer, preventing direct collision between substrates and thus affecting the service life of the buffer assembly.

[0019] To ensure the stability of the device installation;

[0020] As a further improvement to the above technical solution: the anchor bolts are set at the four corners of the mounting plate and the pad.

[0021] The beneficial effects of this improvement are: after the four sets of symmetrically arranged anchor bolts are anchored to the wharf shore, the device can be firmly fixed to the wharf shore with nuts.

[0022] To ensure the connection stability of the pressure plate assembly, buffer assembly, and mounting plate;

[0023] As a further improvement to the above technical solution: the number of connecting bolts is multiple, and they are symmetrically arranged in pairs on the upper and lower sides of the pad.

[0024] The beneficial effects of this improvement are: multiple connecting bolts can stably connect the pressure plate assembly, the buffer assembly, and the mounting plate.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0031] Example 1:

[0032] like Figure 1—3 shows a ship berthing buffer device, including a mounting plate 1, a wooden pad 2 attached to one side of the mounting plate 1, anchor bolts 3 adapted to be inserted into the mounting plate 1 and the wooden pad 2, limit sliders 4 slidably engaged on the upper and lower sides of the mounting plate 1, the limit sliders 4 being installed at the upper and lower ends of limit pins 5, the limit pins 5 being inserted into both ends of a buffer assembly 6, the buffer assembly 6 including a plurality of mutually attached and stacked spring sheets 61, the ends of the spring sheets 61 facing the mounting plate 1 having rolled ears 62 adapted to connect with the limit pins 5, and connecting bolts 63 slidably inserted into the spring sheets 61, the connecting bolts 63 slidingly penetrating through. Mounting plate 1 is threaded with nut 7. One end of connecting bolt 63 is connected to pressure plate assembly 8. Pressure plate assembly 8 abuts against the surface of spring 61 facing away from mounting plate 1. This device has a simple structure and low cost, and can be quickly assembled using bolts, multiple plates, and leaf springs. The buffer assembly 6, in conjunction with pressure plate assembly 8, generates elastic deformation when the ship docks, effectively buffering and protecting the hull. The limiting pin 5 is rotatably inserted into the lug 62. When spring 61 deforms, lug 62 moves through limiting pin 5, driving limiting slider 4 to move. Limiting pin 5 rotates relative to lug 62, and limiting slider 4 moves outside mounting plate 1, ensuring that spring 61... 1. To ensure positional stability and prevent one end of the spring 61 from warping up and causing radial shear force on the connecting bolt 63, the limiting slider 4 is an angle steel structure. The inner wall of the limiting slider 4 is slidably connected to two adjacent sides of the mounting plate 1. The limiting slider 4 serves a limiting function, preventing one end of the spring 61 from warping up during deformation and expansion. The pressure plate assembly 8 includes a rubber plate 81 and a base plate 82. There are multiple connecting bolts 63, one end of which is welded to the base plate 82. The connecting bolts 63 can stably connect multiple springs 61 into one unit. With the use of the nut 7, the buffer assembly 6 is securely installed as a whole on the mounting plate 1. On mounting plate 1, the rubber plate 81 is bonded and fixed to the side of the base plate 82 facing away from the buffer assembly 6. The rubber plate 81 plays an elastic buffering role, avoiding direct collision between base plates 82 and affecting the service life of the buffer assembly 6. The anchor bolts 3 are set at the four corners of mounting plate 1 and pad 2. After the four sets of symmetrically arranged anchor bolts 3 are anchored to the dock shore, they can be used with nuts to firmly fix the device to the dock shore. There are multiple connecting bolts 63, which are symmetrically arranged in pairs on the upper and lower sides of the pad 2. Multiple connecting bolts 63 can stably connect the pressure plate assembly 8, the buffer assembly 6, and the mounting plate 1.

[0033] The working principle of this technical solution is as follows: The device is installed on the dock side by anchor bolts 3. When the ship docks, it comes into contact with the rubber plate 81. The pressure plate assembly 8 is squeezed and displaced, causing the spring 61 to undergo elastic deformation. When the spring 61 deforms, the lug 62 drives the limiting slider 4 to move through the limiting pin 5. The limiting slider 4 moves outside the mounting plate 1 to ensure the stability of the position of the spring 61 and prevent one end of the spring 61 from tilting up and causing the connecting bolt 63 to be subjected to radial shear force. When the spring 61 deforms, it plays an elastic buffering role to prevent the ship from being damaged by rigid collision with the dock.
