Background

According to aluminum gangplank manufactured by the ship industry standard CB3116-1982 aluminum gangplank and the CB/T4218-2013 steel gangplank with rollers and similar steel gangplank, in the actual use process, the gangplank is subjected to deep displacement, transverse displacement and longitudinal displacement due to the influence of tide, and the gangplank also changes along with the movement of a ship body. According to the 'Steel sea vessel entry Standard' of China Classification, the topside strake needs to protrude out of a strong deck. Therefore, when the gangboard is used, one end of the gangboard is lapped on the wharf, and the other end of the gangboard is lapped on the deck surface of the ship body. Along with the movement of the ship body, the ship body end of the springboard moves upwards when the tide rises, a certain included angle is formed between the springboard and the wharf, and the springboard interferes with the shipboard strake to cause the abrasion of the bottom edge of the springboard. When the springboard is pressed to deform downwards, the springboard can interfere with the topside strake, so that the bottom edge of the springboard is worn. The side of the ship body is provided with a railing, and the gangway interferes with the railing when moving left and right to cause the abrasion of the side of the gangway.

As described above, it is a problem to be solved to prevent the wear of the diving board due to collision and friction with the hull structure.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the preferred embodiment of the ship springboard broadside supporting device 100 of the present invention shown in fig. 1 and 2, the roller composed of two short rollers 4 and two long rollers 5 is mounted on the roller shaft 1, wherein the two long rollers 5 are located between the two short rollers 4, and each roller can rotate around the axis of the roller shaft 1. The roller shaft 1 is also provided with a plurality of side clamping plates 3, and in the embodiment, three side clamping plates 3 are respectively arranged at two ends and the middle position (between two long rollers 5) of the roller shaft 1. In addition, two side baffles 2 are further mounted at two ends of the roller shaft 1, and the side baffles 2 are positioned outside the roller and the side clamping plates 3. External threads are processed at two ends of the roller shaft 1, and two fastening nuts 6 are installed at two ends of the roller shaft 1 to play a role in fastening and limiting.

As shown in fig. 2 and 3, the board side card 3 is provided with a card slot 10 that can be clipped on the board top strake 7 of the ship (see fig. 8). As shown in fig. 6 and 7, after the ship diving board broadside supporting device 100 of the present invention is mounted on the roof strake 7 of the hull 300, both ends of the diving board 200 are respectively lapped on the hull 300 and the quay 400, thereby facilitating the boarding and disembarking of personnel. Wherein, the bottom of the springboard 200 contacts with the roller in the supporting device of the invention, so that the sliding friction between the springboard and the topside strake 7 is changed into the rolling friction between the springboard and the roller, thereby avoiding the abrasion of the bottom of the springboard. Part of the ship body is provided with the gunwale railing 8, and the gangway is limited between the two side baffles 2, so that the abrasion of the side edge of the gangway is avoided.

The broadside card 3 is provided with broadside card slots 10, as shown in fig. 3. The depth of the side card slot 10 is the same as the height of the topside strake 7, so that the side card 3 can be stressed as much as possible. The width of the broadside card board clamping groove 10 is larger than that of the broadside strake 7, the proper width is convenient for the installation of the supporting device, and the loose installation is not suitable for use due to the overlarge width. When the ship is installed, the side clamping plate 3 is clamped on the topside strake 7. Wherein, two topside cardboard 3 are installed between side shield 2 and short gyro wheel 4, support short gyro wheel 4 and long gyro wheel 5, and another topside cardboard 3 is installed in the middle part of gyro wheel axle 1, between two long gyro wheels 5, avoids behind the gyro wheel axle 1 atress deformation, long gyro wheel 5 interferes with topside strake 7.

The shaft hole of the board side clamping board 3 is positioned above the side, and after the board side clamping board is installed, the roller shaft 1, the short roller 4 and the long roller 5 can be protruded out of the board side. Thus, the short rollers 4 are suspended outside the topside strake 7 instead of being arranged above the topside strake, so that the design can effectively reduce the height of the short rollers 4 and the long rollers 5 protruding out of the deck, and the springboard is stressed on the springboard strong rollers 9 at the two ends of the springboard as much as possible, thereby avoiding overload damage of the supporting device of the invention.

An avoidance gap 12 is arranged below the side baffle 2, as shown in fig. 4, and the avoidance gap can avoid the roof strake 7. The surface of the side baffle 2 is made of elastic materials, so that the springboard can be better protected, and the service life of the supporting device is prolonged.

The surfaces of the short idler wheels 4 and the long idler wheels 5 are made of elastic materials, and the upper wheel edges of the short idler wheels 4 are higher than the top surface of the board side clamping plate 3, so that the springboard can be ensured to be in contact with the idler wheels of the supporting device on the bottom surface of the springboard only in the use state, and the board side clamping plate 3 cannot be touched. The width B1 of the short roller 4 is larger than the width B2 of the longitudinal frame of the springboard, so that the short roller 4 can relatively independently support the frames at two sides of the springboard, as shown in figure 5.

Preferably, the long roller 5 and the short roller 4 have the same diameter. Because the bottom of part of the springboard is provided with the longitudinal reinforcing ribs 11, the bottom of the middle part of the springboard can be contacted with the long rollers 5 after the springboard is stressed and deformed, so that the local stress points of the springboard are increased, and the stress condition of the springboard is improved. The long roller 5 rotates after contacting with the longitudinal reinforcing rib 11 of the springboard, and the relative motion of the long roller 5 and the short roller 4 with similar diameters is approximately static, so that the friction between the long roller 5 and the short roller 4 is avoided, the abrasion between the rollers is reduced, and the springboard moves more smoothly along with the ship.

The total value of the widths of the three side clamping plates 3, the two short rollers 4 and the two long rollers 5 which are arranged on the roller shaft 1 needs to be properly larger than the width of the springboard, so that the minimum distance between the two side baffles 2 is larger than the width of the springboard in any state, the situation that the springboard cannot be placed into the supporting device is avoided, the distance between the two side baffles 2 is not too large, and the situation that the springboard transversely displaces between the two side baffles 2 is avoided.

In the use state of the ship springboard broadside supporting device shown in fig. 6 and 7, the completely assembled springboard broadside supporting device 100 is mounted on the topside strake 7, and a partial enlarged schematic view can be seen in fig. 8 and 9. The ramp 200 is placed on the deck of the hull 300 at one end and on the quay 400 at the other end by the ramp broadside support 100. Along with the rise tide and the fall tide, the upper ends of the side baffles 2 of the side limiting device are higher than the bottom of the gangway 200 in the using process, and the contact between the gangway 200 and the rollers and/or the side baffles on the side limiting device is soft contact, so that the gangway is effectively protected, and the use of the gangway in a beneficial area is limited.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
