Description

Technical Field

[0001] The present application relates to the field of steel handguards, and in particular, to a ship-friendly steel handguard. Background Art

[0002] A ship lock is a navigation structure that allows ships to overcome concentrated water level differences and is the most commonly used navigation structure in water conservancy and water transport projects. When entering, docking, or exiting a lock chamber, ships often collide, squeeze, and scrape against the lock chamber and navigation wall. Tires are hung on the outside of ships to protect the sides, while guardrails are installed on the upper and lower gates, lock chambers, and navigation wall walls to protect the concrete structure from damage caused by ship collisions and scrapes.

[0003] The steel guardrail is a steel structural member installed on the wall of the lock head, lock chamber and navigation wall and protrudes from the wall.

[0004] Due to the immense inertia of ships, the tire fenders can easily become obstructed by the steel guards during the friction between the ship and the lock wall, leading to rope breakage and tire fall. This leaves the ship unprotected, increasing the risk of damage. A tire that falls into the lock chamber can also interfere with the opening and closing of the lock valves, impacting normal operation and increasing cleaning and maintenance costs. Utility Model Content

[0005] The purpose of the embodiments of the present application is to provide a ship-friendly steel fender to alleviate the technical problem in the prior art that the steel fender has a strong obstructive effect on the ship tire fender, causing the tire to fall off.

[0009] The first protective surface segment and the second protective surface segment extend into the wall at a side away from the first arc-shaped transition surface;

[0010] The maximum distance between the first cladding section and the surface of the wall body is a1, the projection width of the first cladding section on the surface of the wall body is b1, and 1 / 4 < a1 / b1 < 1 / 10; the maximum distance between the second cladding section and the surface of the wall body is a2, the projection width of the second cladding section on the surface of the wall body is b2, and 1 / 4 < a2 / b2 < 1 / 10.

[0011] Further, the first cladding section and the second cladding section are symmetrically arranged about the first arc-shaped transition surface.

[0012] Further, the cladding panel further comprises a first fixed section and a second fixed section, the first fixed section is connected with the side wall of the first cladding section away from the first arc-shaped transition surface at an angle, and the second fixed section is connected with the side wall of the second cladding section away from the first arc-shaped transition surface at an angle.

[0013] Further, the first fixed section and the first cladding section are connected through a second arc-shaped transition surface, and the second fixed section and the second cladding section are connected through a third arc-shaped transition surface.

[0014] Further, the first fixed section, the second arc-shaped transition surface, the first cladding section, the first arc-shaped transition surface, the second cladding section, the third arc-shaped transition surface and the second fixed section are integrally formed.

[0015] Further, the first fixed section and the second fixed section are symmetrically arranged about the first arc-shaped transition surface.

[0016] Further, the ship-friendly steel fender further comprises a connecting assembly, the connecting assembly comprises a first connecting piece and a second connecting piece, the first connecting piece is connected with the first fixed section, and the second connecting piece is connected with the second fixed section.

[0017] Further, the first connecting piece is connected with the surface of the first fixed section facing the first cladding section;

[0018] The second connecting piece is connected with the surface of the second fixed section facing the second cladding section.

[0019] Further, the cladding panel is made of a steel plate.

[0020] Based on the above technical solutions, the technical effects achieved by the present application are analyzed as follows:

[0021] The ship-friendly steel guard provided by the utility model is installed on a wall and includes a guard panel; the guard panel includes a first guard surface segment and a second guard surface segment, the first guard surface segment and the second guard surface segment are connected in a V-shape convex in a direction away from the wall, and the bending part transitions through a first arc-shaped transition surface, and the first arc-shaped transition surface is an arc-shaped convex in a direction away from the wall; the first guard surface segment and the second guard surface segment both extend into the wall on one side away from the first arc-shaped transition surface; the maximum distance between the first guard surface segment and the surface of the wall is a1, the projection width of the first guard surface segment on the surface of the wall is b1, and 1 / 4<a1 / b1<1 / 10; the maximum distance between the second guard surface segment and the surface of the wall is a2, and the projection width of the second guard surface segment on the surface of the wall is b2, and 1 / 4<a2 / b2<1 / 10.

[0022] The first and second guard sections of the ship-friendly steel guard extend into the wall on the side away from the first curved transition surface, and the first and second guard sections are connected in a V-shape that bulges away from the wall, so that the guard panel can be installed on the wall and protect the surface of the wall, preventing ships from hitting the surface of the wall, thereby realizing the basic function of the steel guard.

[0023] The bending part of the first guard surface section and the second guard surface section transitions through a first arc-shaped transition surface, and the first arc-shaped transition surface is an arc convex away from the wall, so as to achieve a smooth transition at the bending part of the guard panel and avoid collision with the ship.

[0024] Assuming the maximum distance between the first guard segment and the wall surface is a1, and the projected width of the first guard segment on the wall surface is b1, 1 / 4 < a1 / b1 < 1 / 10. This increases the cross-sectional width of the first guard segment, the V-shaped opening angle, and the angle at the intersection of the first guard segment and the wall surface. This results in a smoother transition between the first guard segment and the wall surface, reducing the resistance to the tire fender when the ship moves closely against the wall, thereby preventing damage and falloff. This not only protects the ship's structural safety but also mitigates adverse effects on the lock. The smaller the ratio a1 / b1, the less force on the tire fender, resulting in better protection.

[0025] Similarly, assuming the maximum distance between the second guard segment and the wall surface is a2, and the projected width of the second guard segment on the wall surface is b2, 1 / 4 < a2 / b2 < 1 / 10. This increases the cross-sectional width of the second guard segment, the V-shaped opening angle, and the angle at which the second guard segment intersects with the wall surface. This results in a smoother transition between the second guard segment and the wall surface, reducing the resistance to the tire fender when the ship moves closely against the wall, thereby preventing damage and falloff. This not only protects the ship's structural safety but also mitigates adverse effects on the lock. The smaller the ratio a2 / b2, the less force on the tire fender, resulting in better protection.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0037] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0038] In the prior art, the cross section of the steel guardwood structure is generally arc-shaped, see Figure 1 The angle between the arc-shaped steel guardrail 400 and the lock chamber wall is small, which has a significant obstruction effect on the ship's tire fender. Under the dual effects of the ship's forward movement and the squeezing movement against the wall, the tire fender hanging rope is easily subjected to excessive force and broken.

[0039] The ship-friendly steel guard provided by the embodiment of the present invention is installed on the wall 200, including a guard panel 100, the guard panel 100 includes a first guard surface segment 110 and a second guard surface segment 120, the first guard surface segment 110 and the second guard surface segment 120 are connected in a V-shape convex in the direction away from the wall 200, and the bend is transitioned through a first arc-shaped transition surface 130, and the first arc-shaped transition surface 130 is an arc-shaped convex in the direction away from the wall 200; the first guard surface segment 110 and the second guard surface segment 120 are connected in a V-shape convex in the direction away from the wall 200; The side away from the first curved transition surface 130 extends into the wall 200; the maximum distance between the first protective surface segment 110 and the surface of the wall 200 is a1, the projected width of the first protective surface segment 110 on the surface of the wall 200 is b1, and 1 / 4<a1 / b1<1 / 10; the maximum distance between the second protective surface segment 120 and the surface of the wall 200 is a2, the projected width of the second protective surface segment 120 on the surface of the wall 200 is b2, and 1 / 4<a2 / b2<1 / 10.

[0040] Specifically, see Figure 2 and Figure 3In the embodiment, a1 / b1 is set to 1:5, and a2 / b2 is also set to 1:5, which increases the intersection angle of the fender 100 and the wall of the lock chamber, increases from 124° in the prior art to 169°, so that the fender 100 and the wall surface are smoothly transitioned, the resistance of the tire fender is reduced when the ship moves close to the wall, thereby avoiding damage and falling of the tire fender, protecting the structure safety of the ship itself, and reducing the adverse effects on the ship lock. Further, the ship-friendly steel fender also includes a connecting assembly 300 embedded in the wall 200 and connected with the fender 100, so that the fender 100 is stably installed in the wall 200.

[0041] The first fender section 110 and the second fender section 120 of the ship-friendly steel fender extend into the wall 200 away from one side of the first arc-shaped transition surface 130, and the first fender section 110 and the second fender section 120 are connected to protrude in a V shape away from the wall 200, achieving the installation of the fender 100 in the wall 200 and protecting the surface of the wall 200, avoiding the ship from colliding with the surface of the wall 200, and achieving the basic function of the steel fender. The bending portions of the first fender section 110 and the second fender section 120 are transitioned through the first arc-shaped transition surface 130, the first arc-shaped transition surface 130 is in an arc shape protruding away from the wall 200, achieving a smooth transition of the bending portions of the fender 100, and avoiding collision with the ship. The maximum distance between the first fender section 110 and the surface of the wall 200 is a1, and the projection width of the first fender section 110 on the surface of the wall 200 is b1, 1 / 4 < a1 / b1 < 1 / 10. The cross-sectional width of the first fender section 110 is increased, the opening angle of the V shape is increased, and the intersection angle of the first fender section 110 and the surface of the wall 200 is increased, thereby achieving a smooth transition of the first fender section 110 and the surface of the wall 200, reducing the resistance of the tire fender when the ship moves close to the wall, thereby avoiding damage and falling of the tire fender, protecting the structure safety of the ship itself, and reducing the adverse effects on the ship lock. The smaller the ratio of a1 / b1, the smaller the force on the tire fender, and the better the protection effect. Similarly, the maximum distance between the second fender section 120 and the surface of the wall 200 is a2, and the projection width of the second fender section 120 on the surface of the wall 200 is b2, 1 / 4 < a2 / b2 < 1 / 10. The cross-sectional width of the second fender section 120 is increased, the opening angle of the V shape is increased, and the intersection angle of the second fender section 120 and the surface of the wall 200 is increased, thereby achieving a smooth transition of the second fender section 120 and the surface of the wall 200, reducing the resistance of the tire fender when the ship moves close to the wall, thereby avoiding damage and falling of the tire fender, protecting the structure safety of the ship itself, and reducing the adverse effects on the ship lock. The smaller the ratio of a2 / b2, the smaller the force on the tire fender, and the better the protection effect.

[0042] The structure and shape of the ship-friendly steel fender are described in detail as follows:

[0043] In an optional solution of the embodiment of the utility model, the first fender section 110 and the second fender section 120 are symmetrically arranged about the first arc-shaped transition surface 130.

[0044] Specifically, the ratio of a1 / b1 is equal to the ratio of a2 / b2, and the value of a1 is equal to the value of a2, so that the first fender section 110 and the second fender section 120 are symmetric about the first arc-shaped transition, and the middle part of the fender 100 is V-shaped.

[0045] The first fender section 110 and the second fender section 120 are symmetric about the first arc-shaped transition surface 130, which facilitates the manufacture and ensures that the angles between the two sides of the fender 100 and the surface intersection of the wall 200 are increased, so that the two sides of the fender 100 are smoothly transitioned with the surface of the wall 200, the resistance of the tire fender is reduced when the ship moves close to the wall, and the tire fender is prevented from being damaged and falling off, which not only protects the structure safety of the ship itself, but also reduces the adverse effects on the ship lock.

Meanwhile, the second fixed section 150 gradually inclines away from the second fender section 120 from one side to the other side connected with the second fender section 120. The overall width of the fender 100 is increased, and the strength of the fender 100 is greater.

[0048] The first fixed section 140 and the second fixed section 150 increase the length of the ship-friendly steel fender extending into the wall 200, and further increase the contact area of the ship-friendly steel fender with the wall 200, and enhance the connection strength.

The steel bars can be straight, inwardly bent, or outwardly bent, effectively connecting the panel 100 to the concrete structure and ensuring stability. Of course, in addition to welding steel bars to the panel 100 and anchoring them to the concrete wall, the connection assembly 300 can also utilize bolts embedded in the concrete and secure the panel 100 to the wall using nuts.
