Description

Technical Field

[0001] The invention relates to the technical field of rubber fenders, in particular to an anti-collision rubber fender for a dock. Background Art

[0002] Rubber fenders are equipment installed at the edge of docks, rivers and coasts to absorb the collision energy between ships and docks or between ships when docking or mooring, thereby protecting ships and docks from damage.

[0003] In the patent with the publication number of CN114775542A, a high energy absorption ship anti-collision rubber fender is disclosed, including a rubber fender body, a fixing ring is fixedly installed on the outside of the two ends of the rubber fender body, a piston plate is movably installed in the inner cavity of the fixing ring, and a detour is opened on the surface of the piston plate. The present invention avoids direct contact between the surface of the ship and the rubber fender body by setting a first magnetic plate and a second magnetic plate, effectively offsets or consumes a part of the impact force caused by the ship, so that the shock absorption effect of the rubber fender body is better, and a fixing ring, a piston plate, a piston bag and a buffer protection layer are set to effectively avoid a large amount of friction heat between the ship, the buffer protection layer and the pressure guard plate, and effectively strengthen the protective effect of the rubber fender body. By setting the buffer protection layer to be transparent and the inner bottom surface coated with luminous paint, the ship can effectively find the location of the dock and accurately align with the location of the rubber fender body for effective buffering. However, if the ship berths at a certain angle and the impact force is oblique, the impact force will be decomposed into a normal component and a tangential component. The normal component is absorbed by the fender installed at the dock, while the tangential component will increase the lateral load of the fender, which may cause the fender to bend and deform nonlinearly, thereby causing damage to the fender.

[0004] Based on the above situation, the present invention proposes a dock anti-collision rubber fender that can adapt to oblique impact. Summary of the invention

[0005] In order to overcome the disadvantages of the existing dock anti-collision rubber fender that it is easy to bend and deform nonlinearly when subjected to oblique impact, thereby making the fender more easily damaged, the present invention provides a dock anti-collision rubber fender that can adapt to oblique impact.

[0007] Furthermore, a plurality of rubber pads are fixedly connected to the abutment plate.

[0008] Furthermore, it also includes a supporting mechanism for assisting the rubber body to produce regular deformation, the supporting mechanism is arranged between the mounting plate frame and the abutment plate, the supporting mechanism includes a second connecting block, a side of the mounting plate frame close to the abutment plate is connected to a circumferentially distributed second connecting block, a side of the abutment plate close to the mounting plate frame is also connected to a circumferentially distributed second connecting block, an extrusion rod is rotatably connected between the two second connecting blocks located at relative positions of the mounting plate frame and the abutment plate, and a first connecting block is fixedly connected to a side of the extrusion rod close to the inner wall of the rubber body.

[0009] Furthermore, the extrusion rod is bendable and has a certain elasticity.

[0010] Furthermore, it also includes a guiding mechanism for preventing the abutment plate from tilting, the guiding mechanism includes circumferentially distributed guiding ropes, one end of the circumferentially distributed guiding ropes are respectively fixedly connected to the four corners of the abutment plate on one side of the mounting plate frame, the other end of the circumferentially distributed guiding ropes passes through the interior of the mounting plate frame and are respectively fixedly connected to the adjacent bending parts of the extrusion rods, and an integration block is fixedly connected between the circumferentially distributed guiding ropes.

[0011] Furthermore, it also includes a rolling mechanism for reducing friction between the ship and the abutment plate. The rolling mechanism is arranged on the abutment plate.

A telescopic component is fixed between the moving block and the abutment plate, and the moving block is rotatably connected with a roller.

[0012] Furthermore, the rollers are distributed in an oblique and staggered manner to adapt to oblique impacts at multiple angles.

[0013] Furthermore, it also includes a reset mechanism for assisting the rubber body to return to its original state.

[0014] Furthermore, the elastic rope and the tension spring are both made of anti-fatigue materials and are used to assist the rubber body in restoring its original shape.

[0019] 5. The present invention uses elastic ropes, tension springs and other components to assist the rubber body in returning to its original shape when it is no longer squeezed, thereby preventing the rubber body from becoming fatigued or even unable to return to its original shape due to frequent deformation, thereby affecting the subsequent buffering effect and increasing the service life of the dock anti-collision rubber fender.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] A dock anti-collision rubber fender, such as Figure 1-Figure 5 As shown, it includes a mounting plate frame 1, which is fixed to the dock by bolts, a rubber body 11 is fixed to the front side of the mounting plate frame 1, and the rubber body 11 has good elasticity and ductility, a back plate 12 is fixed to the front side of the rubber body 11, and a plurality of rubber cushions are fixed to the front side of the back plate 12 to enhance the buffering effect, and a limit chain 13 symmetrically distributed up and down is fixed between the mounting plate frame 1 and the left side of the back plate 12, and a limit chain 13 symmetrically distributed up and down is also fixed between the mounting plate frame 1 and the right side of the back plate 12. 13 is made of metal and is used to increase the overall stability of the rubber fender. Three hinges 16 distributed vertically up and down are fixedly connected on both sides of the abutment plate 12. A guide plate 14 is fixedly connected between the hinges 16 on the same side. A torsion spring 18 is fixedly connected inside the hinge 16. The torsion spring 18 is used to drive the guide plate 14 to rotate and reset. Draw ropes 17 are slidably connected to the upper and lower sides of the abutment plate 12. Both ends of the draw rope 17 are fixedly connected to the guide plates 14 on both sides. The guide plates 14 are rotatably connected to multiple groups of balls 15 distributed vertically up and down.

[0036] People first install multiple rubber fenders on the edge of the dock or river channel by bolts. Since many modern docks are designed to be long and straight in order to maximize the berthing space, large ships will choose to dock sideways. This method can reduce the risk of collision between the ship and the dock, and sideways docking can make more effective use of the dock space. Therefore, the ship will hit the rubber fender obliquely when docking. When the ship contacts and squeezes the guide plate 14 on one side, the front end of the guide plate 14 will rotate in the direction close to the abutment plate 12 until the guide plate 14 is tightly attached to the abutment plate 12, and the torsion spring 18 will then deform, and the rubber body 11 will deform adaptively. Due to the setting of the guide plate 14, the lateral load generated by the collision can be pre-dispersed when the ship docks sideways, avoiding the rubber fender. The guide plate 14 is easy to be damaged. At this time, since the ship is in a sliding state caused by inertia, when the guide plate 14 on one side rotates, the pull rope 17 is immediately straightened and drives the guide plate 14 on the other side to rotate in the direction close to the abutment plate 12 and to be close to the abutment plate 12, that is, when the guide plates 14 on both sides are close to the abutment plate 12, they will not hinder the sliding of the ship. At this time, the tangential component of the oblique impact of the ship will drive the ball 15 to rotate. The ball 15 can reduce the friction between the ship and the guide plate 14 and extend the service life. When the abutment plate 12 and the guide plate 14 and other components are no longer squeezed by the ship, the guide plate 14 will rotate in the opposite direction and reset under the action of the torsion spring 18, and the pull rope 17 and the rubber body 11 will return to their original state. Since the limit chain 13 is made of metal, the overall stability of the rubber fender can be increased.

[0037] Example 2

[0038] On the basis of Example 1, Figure 6 As shown, it also includes a support mechanism for assisting the rubber body 11 to produce regular deformation. The support mechanism is arranged between the mounting plate frame 1 and the abutment plate 12. The support mechanism includes a second connecting block 22. The front side of the mounting plate frame 1 is fixedly connected with a circumferentially distributed second connecting block 22, and the rear side of the abutment plate 12 is also fixedly connected with a circumferentially distributed second connecting block 22. An extrusion rod 2 is rotatably connected between the two second connecting blocks 22 at corresponding positions. The extrusion rod 2 can be bent and has a certain elasticity. The side of the extrusion rod 2 close to the rubber body 11 is fixedly connected with a first connecting block 21, and the first connecting block 21 is extruded and matched with the rubber body 11.

[0039] When the butt plate 12 and the guide plate 14 are subjected to an oblique impact from a ship, the normal component of the oblique impact from the ship will drive the butt plate 12, the guide plate 14 and other components to move backwards, and the rubber body 11 and the extrusion rod 2 will be squeezed and deformed immediately. The circumferentially distributed first connecting block 21 will move toward the direction close to the rubber body 11 due to the bending of the extrusion rod 2, thereby causing the middle part of the rubber body 11 to deform outwards, so that the impact force acts evenly around the rubber body 11, thereby improving the impact absorption effect of the rubber body 11, and at the same time avoiding excessive damage caused by one side of the rubber body 11 bending inwards and one side bulging outwards.

[0040] like Figure 7-Figure 9 As shown, it also includes a guiding mechanism for preventing the abutment plate 12 from tilting. The guiding mechanism is arranged on the mounting plate frame 1. The guiding mechanism includes four guiding ropes 3. One ends of the four guiding ropes 3 are respectively fixedly connected to the four corners on the rear side of the abutment plate 12, and the other ends of the four guiding ropes 3 pass through the interior of the mounting plate frame 1 and are respectively fixedly connected to the bending parts of the adjacent extrusion rods 2. An integration block 31 is fixedly connected between the four guide ropes 3. The integration block 31 is located inside the four extrusion rods 2. The integration block 31 can ensure that when one of the guide ropes 3 is straightened, the other guide ropes 3 are also in a straightened state.

[0041] When the rubber body 11 and the extrusion rod 2 are squeezed and deformed, the bending of the extrusion rod 2 will pull the guide rope 3, and through the integration block 31, the four guide ropes 3 are all straightened and the support plate 12 moves smoothly backward without tilting, thereby preventing the support plate 12 from tilting and causing one side of the rubber body 11 to be squeezed and the other side to be stretched, thereby causing irregular deformation and damage to the rubber body 11.

[0042] like Fig.10 and Fig.11 As shown, it also includes a rolling mechanism for reducing the friction between the ship and the abutment plate 12. The rolling mechanism is arranged on the abutment plate 12. The rolling mechanism includes a moving block 41. The middle part of the front side of the abutment plate 12 is slidably connected with the moving block 41 distributed longitudinally up and down. A telescopic component 42 is fixedly connected between the moving block 41 and the abutment plate 12. The moving block 41 is rotatably connected with rollers 4. The rollers 4 are obliquely staggered and distributed to adapt to oblique impacts in different directions. The telescopic component 42 is used to ensure that the rollers 4 are close to the ship.

[0043] Since a ship does not move forward smoothly when docking sideways in the water, but will constantly rise and fall with the waves, the ship will drive the abutment 12 to rise and fall. When the ship docks sideways and contacts and squeezes the roller 4, the roller 4 and the moving block 41 will both move backwards, and the telescopic component 42 will be compressed immediately. However, under the action of the telescopic component 42, the roller 4 will be close to the ship. When the ship docks sideways in different directions into the port, impacts in different directions will be generated. The staggered design of the roller 4 is used to buffer the tangential components of impacts in different directions, and the tangential component of the oblique impact of the ship will drive the roller 4 to rotate, thereby reducing the impact of the ship on the abutment 12 and preventing the abutment 12 from moving up and down, causing irregular deformation and damage to the rubber body 11.

[0044] like Fig.12As shown, it also includes a reset mechanism for assisting the rubber body 11 to return to its original state. The reset mechanism is arranged on the rubber body 11. The reset mechanism includes an elastic rope 5. A plurality of groups of circumferentially distributed elastic ropes 5 are fixedly connected to the inner wall of the rubber body 11. A tension spring 51 is fixedly connected to one end of the elastic rope 5 away from the inner wall of the rubber body 11. Both the elastic rope 5 and the tension spring 51 are made of anti-fatigue materials and are used to assist the rubber body 11 to return to its original state. A connecting frame 52 is fixedly connected between the circumferentially distributed tension springs 51.

[0045] When the stop plate 12 and the guide plate 14 are squeezed by the ship and the middle part of the rubber body 11 is deformed outward, the elastic rope 5 and the tension spring 51 are stretched. When the stop plate 12 and the guide plate 14 and other components are no longer squeezed by the ship, the rubber body 11 returns to its original state under the assistance of its own elasticity and the elastic rope 5 and the tension spring 51. The presence of the elastic rope 5 and the tension spring 51 can reduce the fatigue of the rubber body 11 caused by deformation, thereby ensuring the buffering effect and improving the service life of the rubber body 11.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
