Description

Steel bumper

Technical field

The invention relates to the technical field of protective devices for ship docking, in particular to a steel bumper.

Background technique

After the completion of the ship built on the ground, the ship must be transported to the semi-submersible barge by means of a transfer trolley. Before lifting, the semi-submersible barge must first dock and dock with the ground track. The semi-submersible barge and the dock usually have buffers to prevent the semi-submersible barge from directly contacting the dock. When the cushioning member provided between the semi-submersible barge and the dock is a skid or rubber mat, the semi-submersible barge has a large pressing force on the dock when the ship is lifted, so that the skid or the rubber mat is easily compressed, resulting in The relative distance between the semi-submersible barge and the ground varies greatly, or the semi-submersible barge is not on the same line as the ground track, resulting in a certain risk of lifting the ship. The cushioning device between the semi-submersible barge and the pier is a steel bump. When the mat is used, the steel bumper is usually thicker than the rubber fender of the dock, which causes the steel bumper to be removed when the dock stops at other ships, so that the ship can lean against the rubber fender, making the setting of the steel bumper more inconvenient.

Summary of the invention

The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in FIGS. 1 to 3, in the present embodiment, a steel bumper according to the present invention includes a first steel bumper 3 disposed on the wharf 1 and a second steel disposed on the hull panel 21 The first steel bumper 3 and the second steel bumper 4 are correspondingly positioned and selectively abuttable, the first steel bump 3 has a thickness L1, and the second steel touches The thickness of the pad 4 is L, and the rubber fender 5 provided on the wharf 1 is The thickness L3, the thickness L1 of the first steel pad 3, the thickness L of the second steel pad 4, and the working thickness L3 of the rubber fender 5 have the following relationship: L1+L>L3 And L1 < L3.

The first steel bumper 3 and the second steel bumper 4 are respectively arranged on the dock 1 and the semi-submersible barge, and the first steel bumper 3 and the second steel bumper 4 are used when the semi-submersible barge is docked 1 The semi-submersible barge can be cushioned when docking 1 to prevent the semi-submersible barge from directly colliding with the dock 1 to cause damage to the hull 2 or the pier 1. At the same time, the thickness L1 of the first steel bump 3 is smaller than the working thickness L3 of the rubber fender 5 provided on the dock 1, and can be cushioned by the rubber fender 5 when other ships are docked 1 and does not collide. The first steel bumper 3 can realize the reliance of the semi-submersible barge and other ships without removing the first steel bumper 3.

Specifically, the working thickness of the rubber fender 5 described above is the minimum thickness of the rubber fender 5 after being squeezed during operation.

The thickness of the first steel baffle 3 is set to be smaller than the minimum thickness of the rubber fender 5 which is compressed by the ship, and the other steels are always not in contact with the first steel baffle during the process of stopping using the rubber fender 5. Collision to avoid collision damage to the anchored ship, to ensure that the first steel bump 3 does not need to be disassembled after installation, and it is convenient for all kinds of ships to dock 1.

Preferably, a side of the first steel baffle 3 away from the wharf 1 is provided with a recess 6 recessed toward the wharf 1. When the hull 2 approaches the wharf 1, the second steel baffle 4 can be inserted into the recess 6 of the first steel bumper 3.

Further, a protrusion corresponding to the groove 6 is disposed on the second steel pad 4, and a protrusion provided on the second steel pad 4 is selectively inserted into the groove 6. It is possible to prevent the hull 2 from colliding with the first steel bump 5 after the second steel bump 4 is inserted into the groove 6, thereby damaging the structure of the hull 2.

The matching groove 6 and the protruding structure are arranged to assist the quick and accurate docking of the semi-submersible barge and the dock 1 in the process of the semi-submersible barge, and the semi-submarine barge can be restricted after the docking is completed. The movement of the head 1 in the parallel direction avoids the relative displacement of the semi-submersible barge and the dock 1 when lifting the cargo to the semi-submersible barge platform, further ensuring the safety during the lifting process.

Preferably, the side wall of the recess 6 is provided with an inclined surface for guiding the insertion of the projection.

Specifically, the groove bottom width of the groove 6 is smaller than the groove width of the groove 6, and the shape of the protrusion is matched with the groove 6.

In another specific embodiment, the side wall of the groove 6 is provided with a diagonal pad so that the groove bottom width of the groove 6 is smaller than the groove width.

Further, a circular arc transition structure is disposed between the notch of the groove 6 and the side of the first steel bump 3 away from the wharf 1. The arc transition structure is specifically to round the notch edge of the groove 6.

The guiding surface and the arc transition structure can be used to guide the second steel baffle 4 when the semi-submersible barge is docked 1 to realize the rapid positioning of the semi-submersible barge, saving the time of positioning and accelerating Work efficiency.

In other embodiments, it is also possible to provide a recess 6 on the second steel bump 4 and a projection on the first steel bump 3.

Preferably, as shown in FIG. 4 , the first steel pad 3 includes a limiting seat 31 fixedly disposed on the dock, and the steel pad body 32 is disposed in the limiting seat 31 , and the steel pad body 32 is disposed. An elastic buffer mechanism 33 is disposed between the bottom of the limiting seat 31.

Specifically, the elastic buffer mechanism 33 is a plurality of springs evenly distributed around the bottom of the steel pad body 32 near the limiting seat 31.

Further, the spring is supported by high-strength steel, and the steel pad body 32 always has a tendency to move away from the side of the dock 1 under the elastic force of the spring.

The elastic buffer mechanism 33 is arranged such that the first steel bumper 3 has a certain elasticity, and the buffering effect is enhanced when the semi-submersible barge is fastened, and the outer hull plate 21 of the semi-submersible barge is further protected from damage.

Preferably, the number of the first steel bumper 3 and the second steel bumper 4 is two, and the two first steel bumpers 3 are symmetrically disposed on both sides of the center line of the dock 1.

Further, the two first steel bumpers 3 are respectively disposed on both sides of the rubber fender 5 away from the center line of the wharf 1.

The two first steel bumps 3 can be arranged to buffer the anti-collision from the plurality of positions to the semi-submersible barge, and the plurality of steel bumps can be arranged to facilitate positioning of the semi-submersible barge. Thereby achieving a quick ride of the semi-submersible barge.

Preferably, the first steel bump 3 is fixedly disposed on the embedded steel plate 7 of the wharf 1 by welding. The second steel bump 4 is welded and fixed to the outer hull plate 21, and the hull plate 21 is correspondingly provided with a reinforcing structure.

The first steel bumper 3 and the second steel bumper 4 are directly welded to the pre-buried steel plate 7 and the hull plate 21 of the wharf 1 to realize the fixing of the steel bumper, and the steel bump pad installation described in the present invention is installed. It does not need to be disassembled afterwards, so it can be directly fixed to the wharf 1 and the hull plate 21 by welding. Fixing the first steel bump 3 by using the steel plate pre-buried by the pier 1 can ensure the stable fixation of the first steel bump 3, and at the same time effectively prevent the use of the steel bump to damage the dock 1, and the second steel bump 4 is welded. On the hull plate 21, at the same time, the corresponding position of the hull plate 21 is reinforced to ensure that the force applied to the second steel pad 4 can be uniformly distributed to the hull plate 21 during the tying process, thereby preventing The stress concentration causes damage to the hull plate 21 of the hull.
