Description

Technical Field

[0001] The utility model relates to the field of ships, in particular to an anti-collision buffer device for ships. Background Art

[0002] Ship anti-collision buffer devices usually include anti-collision buffer rubber products, which are designed to reduce the damage caused by collision when the ship is berthed or in contact with other ships. These buffer devices can protect the hull and the dock by absorbing and dispersing the collision energy.

[0003] In order to reduce the losses caused by collisions of ships, it is necessary to use a ship anti-collision buffer device to reduce damage. For example, the prior art Chinese patent announcement number "CN220535915U" discloses a ship with anti-collision buffer function, which relates to the field of ship anti-collision technology, including a hull structure component, the outer end of the hull structure component is connected and installed with two side buffer components, the two side buffer components include a groove, the upper end of the groove is inserted and installed with a connecting plate, the upper end of the connecting plate is installed and connected with a pad, the upper end of the pad is fixed with a spring, and the two sides of the spring are parallelly installed with a first buffer, the front end of the two side buffer components is connected and installed with a front end buffer component, the front end buffer component includes a second buffer, the outer end of the front end buffer component is connected and fixed with an anti-collision component, the upper end of the anti-collision component is fixed with a connecting groove, the interior of the connecting groove is installed and connected with a coupling capsule, and the upper end of the coupling capsule is connected with an annular airbag. This device effectively prevents the hull or edge of the ship from colliding with the dock, causing wear and damage at the collision site of the ship.

[0004] Some anti-collision buffer devices are provided with structural plates on the periphery of the ship, and springs and buffers are provided between the hull and the structural plates for anti-collision buffering. However, in actual operation, it is considered that relying solely on springs and buffers cannot effectively play an anti-collision buffering role for the hull. The reverse thrust generated by the expansion and contraction of the springs under severe collisions will also affect the hull. In addition, the structural plates cannot be disassembled and replaced, and long-term use is inconvenient for maintenance and replacement, and has low practicality. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art, that is, the poor anti-collision and buffering effect and the inconvenience of replacing the buffer body, and proposes a ship anti-collision and buffering device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Furthermore, the buffer assembly includes a piston cylinder, the piston cylinder is fixedly installed in the installation box, and a piston head is slidably connected in the piston cylinder.

[0009] Furthermore, a spring is fixedly connected to the inner bottom surface of the piston cylinder, the other end of the spring is fixedly connected to one end of the piston head, and a vent hole is opened on the side of the bottom of the piston cylinder.

[0010] Furthermore, a guide groove is opened on the side of the installation box, and the other end of the piston head is rotatably connected to a first connecting rod, and the first connecting rod is slidably connected to the guide groove. The end surface of the fixed seat is located between a pair of the installation boxes and is rotatably connected to a second connecting rod, and the first connecting rod is rotatably connected to the other end of the second connecting rod.

[0011] Furthermore, the connecting assembly includes a connecting seat, and the side of the buffer body is clamped with the connecting seat through an installation groove. One side of the connecting seat is provided with a locking groove and a receiving groove, and one end of the first connecting rod that rotates with the second connecting rod is rotatably connected in the receiving groove through a fixing pin.

[0012] Furthermore, the buffer body is rotatably connected to an unlocking rod in the installation groove, a curved rod is fixedly installed on the periphery of the unlocking rod, and torsion springs are sleeved on both ends of the unlocking rod beside the curved rod, and the curved rod can be snapped into the locking groove.

[0013] The utility model proposes an anti-collision buffer device for ships, the beneficial effects of which are: the utility model can effectively play an anti-collision buffer role to protect the hull, by squeezing the buffer body backward under pressure and pushing a pair of connecting rods, and then dispersing the pressure brought by the buffer body under the cooperation of the connecting rods and the piston head to play a buffering role, and the buffer body and the fixed seat can be easily disassembled and assembled through the connecting assembly, which is convenient for maintenance and replacement of the buffer body, and has strong practicality.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5 A ship anti-collision buffer device comprises a fixing seat 1 and a buffer body 2 installed on the hull, at least one pair of installation boxes 3 are fixedly installed on the end surface of the fixing seat 1, and a buffer assembly 4 for anti-collision buffering is arranged in the installation box 3. The buffer body 2 is detachably connected to the fixing seat 1 through a connecting assembly 5, and the pressure-bearing side of the buffer body 2 is an arc-shaped structure.

[0022] Specifically, the buffer assembly 4 includes a piston cylinder 41 , which is fixedly installed in the installation box 3 , and a piston head 42 is slidably connected in the piston cylinder 41 .

[0023] Furthermore, a spring 43 is fixedly connected to the inner bottom surface of the piston cylinder 41, and the other end of the spring 43 is fixedly connected to one end of the piston head 42. A vent hole 411 is opened on the side of the bottom of the piston cylinder 41. When the buffer body 2 is subjected to pressure and squeezes the first connecting rod 45 and the second connecting rod 46 backward, the piston head 42 will be pressed to slide against the spring 43, and the gas will be squeezed and slowly discharged from the vent hole 411, thereby achieving the purpose of buffering, and then the spring 43 returns the buffer body 2 to its original position under the action of elastic support.

[0024] In more detail, a guide groove 44 is opened on the side of the installation box 3, and the other end of the piston head 42 is rotatably connected to the first connecting rod 45, and the first connecting rod 45 is slidably connected to the guide groove 44. The end surface of the fixed seat 1 is located between a pair of the installation boxes 3 and is rotatably connected to the second connecting rod 46. The first connecting rod 45 is rotatably connected to the other end of the second connecting rod 46, and the guide groove 44 provides space for the first connecting rod 45 to slide and prevent it from getting stuck.

[0025] In general, the connecting assembly 5 includes a connecting seat 51, and the side of the buffer body 2 is clamped with the connecting seat 51 through a mounting groove 52. A locking groove 53 and a receiving groove 54 are opened on one side of the connecting seat 51. The first connecting rod 45 and the second connecting rod 46 are rotated at one end and connected to the receiving groove 54 through a fixing pin 541. The connecting seat 51 and the mounting groove 52 are both wedge-shaped structures. The advantage is that the mounting groove 52 utilizes the wedge-shaped feature of the bottom to clamp the bottom of the connecting seat 51, and then the curved rod 56 clamps the top of the connecting seat 51 to achieve a fixing effect. It is worth mentioning that the mounting groove 52 is larger than the connecting seat 51, leaving space for clamping the bottom of the connecting seat 51.

[0026] Finally, the buffer body 2 is rotatably connected to the unlocking rod 55 in the installation groove 52, and a curved rod 56 is fixedly installed on the periphery of the unlocking rod 55. The two ends of the unlocking rod 55 are located next to the curved rod 56 and are sleeved with torsion springs 57. The curved rod 56 can be snapped into the locking groove 53. The unlocking rod 55 is rotatably connected to the buffer body 2, and one end of the unlocking rod 55 passes through the buffer body 2 and is fixedly installed with a handle 551. The torsion spring 57 is used to enable the curved rod 56 to be snapped into the locking groove 53. The unlocking rod 55 is rotated by the handle 551 to disengage the curved rod 56 from the locking groove 53.

[0027] Working method: When working, the unlocking rod 55 is rotated by the handle 551 to rotate the curved rod 56, and then the connecting seat 51 is inserted into the installation groove 52. The curved rod 56 is clamped into the locking groove 53 under the action of the torsion spring 57. When the buffer body 2 is pressurized, the first connecting rod 45 and the second connecting rod 46 are squeezed backward. The first connecting rod 45 cooperates with the piston head 42 to make the buffer body 2 move slowly, thereby achieving the effect of anti-collision and buffering.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
