in the figure: the structure comprises a top surface 1, a side wall 2, a circular arc transition section 3, a lower flange 4, an anti-slip strip 5, a gangplank main body 6, a protective cap shaped like a Chinese character 'omega', a side plate 8, an upper panel 9, a lower panel 10, a connecting hinge 11, a longitudinal truss 12, a longitudinal beam 13 and a diaphragm plate 14.

Detailed Description

As shown in fig. 1, the present embodiment relates to a ship anti-skid springboard with an integrated protective cap, which comprises: the springboard comprises a springboard main body 6 and anti-slip strips 5 arranged on the upper surface of the springboard main body in parallel, wherein omega-shaped protective caps 7 are clamped on the anti-slip strips 5.

The anti-skid strips 5 are made of rectangular flat steel or flat aluminum alloy in cross section.

As shown in fig. 2 and 3, the diving board main body 6 includes: the side plates 8, the upper plate 9, the lower plate 10 and a longitudinal skeleton type framework system formed by longitudinal girders 12, transverse clapboards 14 and longitudinal ribs 13, wherein one end of the springboard main body 6 close to the ship body is connected with other ship body structures through a connecting hinge 11. The upper panel of the main body of the gangway is provided with an anti-slip strip 5.

The parallel arrangement means that: the anti-skid strips 5 are divided into two groups and are respectively arranged in the areas where the vehicles and the crawler belts pass on the surface of the upper surface of the springboard main body, and the distance between the two areas is determined according to the actual use scene and is generally about the width between the left wheel and the right wheel of the vehicle or the two crawler belts of the crawler belt equipment. The anti-slip strips 5 are fixed on the upper panel 9 through welding, and the arrangement direction of each anti-slip strip is consistent with the width direction of the springboard main body. Two sets of antislip strips are all arranged in parallel, the arrangement direction of each antislip strip in the set is consistent with the advancing direction when boarding or disembarking, and the distance between the adjacent antislip strips can be about 200 mm.

The omega-shaped protective cap 7 comprises: top surface 1, be located the lateral wall 2 of top surface both sides and the bottom flange 4 that links to each other with lateral wall 2, wherein: an arc transition section 3 is arranged between the lower flange 4 and the side wall 2.

The top surface 1 and the side wall 2 form an inverted U-shape.

The omega-shaped protective cap 7 is preferably made of steel, and when the protective cap is not installed on the anti-skid strip, the angle between the side wall 2 and the top surface 1 is 84-86 degrees, so that the side wall is slightly tightened inwards on one side of the opening.

The minimum distance between the arc transition sections 3 is smaller than the width of the upper surface of the anti-skid strip 5.

When the anti-skid device is installed, the arc transition section 3 abuts against the edges and corners formed by the two side faces of the anti-skid strip 5 and the upper surface, downward force is applied to the protective cap, the anti-skid strip is easily embedded between the two side walls of the protective cap due to the existence of the arc transition section, the two side walls of the protective cap are automatically slightly expanded, and the forced deformation of the protective cap generates pre-tightening force, so that the side walls of the protective cap automatically clamp the side faces of the anti-skid strip; after the anti-skid device is installed, two side walls of the protective cap are tightly attached to a pair of side surfaces of the anti-skid strips, the top surface of the protective cap is tightly attached to the upper surfaces of the anti-skid strips, and the anti-skid strips are integrally embedded into the protective sleeve.

The lower flange 4 is attached to the upper surface of the diving board main body 1 after being installed, thereby transferring a load part to the diving board main body. The radius of the arc transition section 3 between the lower flange 4 and the side wall 2 is 1/5-1/3 of the height of the anti-slip strip, so that a certain gap exists between the arc transition section 3 and the root of the anti-slip strip, the improvement of the loaded state of the anti-slip strip is facilitated, and the stress concentration of the root of the anti-slip strip is prevented.

As shown in fig. 7, the lower flange 4 on one side of the Ω -shaped protective cap and the arc transition section 3 of the sidewall 2 may be replaced by a right-angle connection form, that is, the arc transition section 3 is eliminated, and the sidewall 2 and the lower flange 4 are directly connected, and the included angle is a right angle. In this embodiment, the side wall 2 on this side does not need to be angled slightly inwardly with respect to the top side 1 of the protective cap.

Compared with the prior art, the utility model discloses a omega font protective cap can directly be applied to welded fastening's springboard antislip strip, can not only alleviate the antislip strip damage, can also be through unique structural style, more evenly conduct the track load that the antislip strip bore to the springboard major structure to improve the loaded condition of antislip strip and springboard, further improve its reliability. In addition, the protective cap replaces the anti-skid strip to be in direct contact with the load, when slight damage such as surface abrasion occurs, only the protective cap needs to be replaced, and the service cycle of the anti-skid strip can be prolonged. The protective cap can be made of common steel materials, so that the cost is low; simultaneously, the pretightning force of protective cap through self can be realized fixedly with the help of other modes not, easily installs, dismantles and changes, consequently compares in current scheme, the utility model discloses also have the advantage in the aspect of economic nature.

The foregoing embodiments may be modified in various ways by those skilled in the art without departing from the spirit and scope of the present invention, which is not limited by the above embodiments but is to be accorded the full scope defined by the appended claims, and all such modifications and variations are within the scope of the invention.
