Description

Technical Field

[0001] The present application belongs to the field of ship technology, and specifically relates to a ship ladder. Background Art

[0002] In the related art, a ship ladder is a tool connected between the hull and the dock for people to get on and off the ship. One end of the ship ladder is hung on the hull, and the other end of the ladder is directly placed on the ground of the dock. Since the ship ladder moves with the waves, there is no stable connection between the other end of the ladder and the bottom surface of the dock, which causes the other end of the ladder to move with the ladder, causing inconvenience to people getting on and off the ship, and even leading to safety accidents. Summary of the Invention

[0003] The present application aims to at least to some extent solve the technical problem of unstable connection of a ship ladder between a ship hull and a dock. To this end, the present application provides a ship ladder.

[0004] The technical solution of this application is:

[0005] The present application provides a ship ladder, comprising:

[0006] ontology;

[0007] a sliding member, slidably disposed at one end of the body along the length direction of the body;

[0008] The rotating member is rotatably connected to the other end of the body.

[0009] Furthermore, one end of the body is connected to the hull via the sliding member, and the other end of the body is connected to the dock via the rotating member.

[0010] Furthermore, the sliding member includes:

[0011] Bracket;

[0012] A roller is provided on the bracket;

[0013] a hook, arranged on the bracket;

[0014] The ship ladder further comprises a slide member, wherein the slide member is provided with a slide groove along the length direction of the slide member, the slide member is arranged on the body along the length direction of the body, and the roller is arranged in the slide groove.

[0015] Furthermore, the opening direction of the chute is the direction of the bottom surface of the main body, and the wheel surface of the roller is rollingly connected to the bottom surface of the chute.

[0016] Furthermore, one end of the rotating member is rotatably connected to the other end of the body, and the other end of the rotating member is connected to the convex edge of the dock.

[0017] Furthermore, the other end of the rotating member is a U-shaped structure, and the other end of the rotating member is buckled on the convex edge.

[0018] Furthermore, the ship ladder also includes a railing, and the railing is arranged on the body.

[0019] Furthermore, the ship ladder also includes a protective net, which is arranged at the bottom of the body.

[0020] Furthermore, the ship ladder also includes support rods, which are arranged on both sides of the length direction of the main body, and the protective net is fixed on the support rods.

[0021] Furthermore, the support rod is rotatably arranged on the body.

[0022] The embodiments of the present application have at least the following beneficial effects:

[0023] The present application provides a ship ladder that can connect one end of its main body to a ship's hull and the other end to a dock. Specifically, one end of the main body is connected to the hull via a sliding member, while the other end of the main body is connected to the dock via a rotating member. As the hull moves with waves, one end of the main body slides relative to the hull to primarily eliminate the impact of the hull's vertical movement on the ladder. Furthermore, the other end of the main body rotates with the dock to eliminate the impact of the hull's horizontal movement on the ladder.

[0024] Of course, one end of the main body can also be connected to the dock and the other end to the hull, that is, one end of the main body can be connected to the dock via a sliding member, and the other end of the main body can be connected to the hull via a rotating member. When the hull moves with the waves, one end of the main body slides relative to the dock to eliminate the impact of the hull's horizontal movement on the hull, and the other end of the main body rotates with the hull to eliminate the impact of the hull's vertical movement and the ladder.

[0025] In summary, with the two main body settings mentioned above, the two ends of the main body are connected between the hull and the dock by sliding connection and rotating connection respectively. The sliding connection can enable one end of the main body to slide within a certain range relative to the hull or the dock. Therefore, the ship ladder in this application can achieve a stable connection between the hull and the dock, thereby improving the safety of the use of the ship ladder.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] In addition, this application may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0033] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0034] Figure 1 as well as Figure 2 A ship ladder according to an embodiment of the present application, combined with Figure 1 as well as Figure 2The ship ladder includes a main body 100, a sliding member 200 and a rotating member 300, wherein the main body 100 is the ladder structure for walking on the ship ladder, the sliding member 200 can be slidably arranged at one end of the main body 100 along the length direction of the main body 100, and the rotating member 300 can be rotatably connected to the other end of the main body 100.

[0035] Specifically, combined Figure 1 as well as Figure 2 One end of the main body 100 can be connected to the hull, and the other end of the main body 100 can be connected to the dock. That is, one end of the main body 100 is connected to the hull via a sliding member 200, and the other end of the main body 100 is connected to the dock via a rotating member 300. When the hull moves with the waves, one end of the main body 100 slides relative to the hull to mainly eliminate the influence of the vertical movement of the hull and the ladder. In combination with the rotation between the other end of the main body 100 and the dock, it eliminates the influence of the horizontal movement of the hull on the hull.

[0036] Of course, one end of the body 100 can also be connected to the dock, and the other end of the body 100 can be connected to the hull. That is, one end of the body 100 is connected to the dock via the sliding member 200, and the other end of the body 100 is connected to the hull via the rotating member 300. When the hull moves with the waves, one end of the body 100 slides relative to the dock to eliminate the impact of the horizontal movement of the hull on the hull. In combination with the rotation between the other end of the body 100 and the hull, the vertical movement of the hull and the influence of the ladder are eliminated.

[0037] In summary, with the two ways of setting up the main body 100, the two ends of the main body 100 are connected between the hull and the dock by sliding connection and rotating connection respectively, wherein the sliding connection can enable one end of the main body 100 to slide within a certain range relative to the hull or the dock. Therefore, the ship ladder in the embodiment of the present application can achieve a stable connection between the hull and the dock, thereby improving the safety of the use of the ship ladder.

[0038] In the implementation of this application, a connection method is adopted in which one end of the main body 100 is connected to the hull through a sliding member 200, and the other end of the main body 100 is connected to the dock through a rotating member 300. Through this setting method, it can be ensured that the other end of the main body 100 and the dock are in a rotational connection, and the endpoint of the other end of the main body 100 remains fixed on the dock, thereby setting a fixed boarding point or disembarkation point at the dock.

[0039] In addition, since the vertical movement amplitude of the hull is greater than the horizontal movement amplitude of the hull, slidingly connecting one end of the main body 100 to the hull can improve the ship ladder's ability to offset the vertical movement of the hull.

[0040] Combine Figure 1 as well as Figure 2 The sliding member 200 includes a bracket 210, a roller 220, and a hook 230. The ship ladder also includes a chute member 400. The roller 220 is mounted on the bracket 210, and the hook 230 is mounted on the bracket 210. The chute member 400 has a chute 410 along its length. The chute member 400 is mounted on the body 100 along its length. The roller 220 is mounted within the chute 410 of the chute member 400. By hooking the hook 230 on the hull, one end of the body 100 is fixed to the hull. The hook 230 also facilitates removal of the ship ladder from the hull. When the hull moves with the waves, the roller 220 rolls within the chute 410, thereby achieving a sliding connection between one end of the body 100 and the hull, thereby offsetting the impact of the hull's movement on the ship ladder.

[0041] Of course, in some other embodiments, the roller 220 may be set on the main body 100 and the slide member 400 may be set on the bracket 210 to achieve the same use effect, and the embodiment of the present application does not limit this.

[0042] In addition, the slide member 400 can also be set vertically. This is not limited to the embodiment of the present application. The slide member 400 is set vertically so that one end of the main body 100 can only offset the movement of the hull in the vertical direction, and the slide member 400 is set along the length direction of the main body 100, so that one end of the main body 100 can offset the movement of the hull in both the vertical and horizontal directions.

[0043] In the embodiment of the present application, the clamping width of the hook 230 can be adjusted to adapt to different hull structures. Figure 1 as well as Figure 2 In the embodiment, the hook 230 may include a fixed plate 231, a movable plate 232, a connecting plate 233 and a screw 234, wherein the fixed plate 231 is connected to the bracket 210, the fixed plate 231 and the movable plate 232 are arranged opposite to each other, the fixed plate 231 and the movable plate 232 are connected through the connecting plate 233, a sliding hole 235 is opened on the connecting plate 233, the screw 234 is passed through the sliding hole 235, and is threadedly connected to the movable plate 232, so that the movable plate 232 is movably set on the connecting plate 233, so that when the movable plate 232 is adjusted to the required position, the screw 234 can be tightened to fix the movable plate 232 on the connecting plate 233.

[0044] In the embodiment of the present application, both ends of the chute member 400 in the longitudinal direction are closed structures, thereby limiting the roller 220 in the chute 410. The length of the chute 410 is the range of motion of the roller 220. In addition, the roller 220 is fixed in the chute 410 to prevent the roller 220 from falling out of the chute 410 and causing a safety accident. Figure 1as well as Figure 2 In the figure, the roller 220 is arranged in the slide groove 410, and the slide groove member 400 is provided with relative moving openings 420 on both sides of its length direction along its length direction. The two ends of the fixed shaft 221 of the roller 220 respectively extend out of the moving openings 420 on both sides of the length direction of the slide groove member 400, and the bracket 210 is connected to the two ends of the fixed shaft 221, thereby realizing the fixed setting of the roller 220 in the slide groove 410.

[0045] In the embodiment of the present application, in order to ensure the connection stability of the ship ladder, two or more parallel sliding groove members 400 and corresponding rollers 220 are provided, and the embodiment of the present application does not limit this.

[0046] Combine Figure 1 as well as Figure 2 The opening direction of the chute 410 is toward the bottom surface of the body 100, and the wheel surface of the roller 220 is in rolling connection with the bottom surface of the chute 410, thereby realizing the movement of the roller 220 in the longitudinal direction of the body 100. When this arrangement is adopted, the roller 220 and the hook 230 are arranged opposite to each other on the bracket 210.

[0047] The opening direction of the chute 410 can be arranged along the bottom surface of the body 100, and the wheel surface of the roller 220 can be rollingly connected to the two side surfaces of the chute 410. Alternatively, the opening direction of the chute 410 can be arranged along the width direction of the body 100, and the wheel surface of the roller 220 can be rollingly connected to the bottom surface of the chute 410. This embodiment of the present application is also not limited to this. However, the above two arrangements will cause the roller 220 to be subjected to excessive axial force, thereby reducing the rolling effect of the roller 220.

[0048] In an embodiment of the present application, one end of the rotating member 300 is rotatably connected to the other end of the main body 100, and the other end of the rotating member 300 is connected to the convex edge of the dock, thereby realizing a rotational connection between the ship ladder and the dock, and the rotating member 300 can be set in the area of ​​the projection of the ship ladder on the dock to avoid the ship ladder occupying too much space on the dock.

[0049] Combine Figure 1 as well as Figure 2 One end of the rotating member 300 can be two parallel rotating rods, and one end of the two rotating rods is connected to the other end of the main body 100 through a rotating shaft arranged along the width direction of the main body 100, thereby realizing the rotational connection between one end of the rotating member 300 and the other end of the main body 100.

[0050] Combine Figure 1 as well as Figure 2The other end of the rotating member 300 can be a U-shaped plate. The two rotating rods at one end of the rotating member 300 are connected to the U-shaped structure at the other end of the rotating member 300. A convex edge is provided on the dock. The U-shaped structure at the other end of the rotating member 300 matches the shape of the convex edge, so that the U-shaped structure at the other end of the rotating member 300 is buckled on the convex edge to fix the rotating member 300.

[0051] In the embodiment of the present application, the ship ladder further includes a railing 500, which is provided on the body 100 to ensure the safety of the ship ladder. Figure 1 as well as Figure 2 In the embodiment, two rows of railings 500 are arranged along the length direction of the main body 100 and are arranged on both sides of the length direction of the main body 100.

[0052] In the embodiment of the present application, the ship ladder further includes a protective net, which is arranged at the bottom of the body 100 to ensure the safety of the ship ladder.

[0053] In the embodiment of the present application, the ship ladder further includes a support rod 600, and a support rod 600 is provided on both sides of the length direction of the body 100, and the protective net is fixed on the support rod 600 to fix and support the protective net through the support rod 600. Figure 1 as well as Figure 2 In the figure, two support rods 600 are provided at both ends of the main body 100 and are arranged opposite to each other on both sides of the length direction of the main body 100. Of course, the number of pairs of support rods 600 can be set according to the length of the ship ladder. This is not limited in the embodiment of the present application. In addition, a fixing ring 630 is provided at the end of the support rod 600 away from the main body 100, so that the corners of the anti-skid net are connected to the fixing ring 630 of the support rod 600.

[0054] In an embodiment of the present application, the support rod 600 can be rotatably arranged on the main body 100, so that the support rod 600 can be switched from being arranged along the length direction of the main body 100 to being arranged along the width direction of the main body 100. When the support rod 600 is arranged along the length direction of the main body 100, the support rod 600 can be stored on the main body 100. When the support rod 600 is arranged along the width direction of the main body 100, the support rod 600 can be fully unfolded to achieve the maximum unfolding area of ​​the protective net.

[0055] Combine Figure 1 as well as Figure 2The ship ladder also includes a fixing frame 700, which is arranged corresponding to the support rod 600. The fixing frame 700 is arranged on the body 100 along the width direction of the body 100, and the support rod 600 is rotatably arranged on the fixing frame 700. The fixing frame 700 is provided with a flat plate 710 parallel to the top surface of the body 100, and a vertical plate 720 perpendicular to the flat plate 710. A round rod 730 perpendicular to the flat plate 710 is provided on the flat plate 710. One end of the support rod 600 is radially opened. There is a rotation hole 610, and the round rod 730 of the fixing frame 700 is passed through the rotation hole 610 of the support rod 600. The circumferential surface of the support rod 600 is connected to the surface of the flat plate 710. When the support rod 600 is rotated to the length direction of the main body 100, the circumferential surface of the support rod 600 is connected to the side surface of the main body 100. When the support rod 600 is rotated to the width direction of the main body 100, the circumferential surface of the support rod 600 is connected to the surface of the vertical plate 720, so as to limit the support rod 600 through the vertical plate 720.

[0056] In order to ensure that the support rod 600 remains stable when it is rotated to the width direction of the main body 100, a fixing hole 620 is opened in the radial direction of the support rod 600, and a circular groove 740 corresponding to the fixing hole 620 of the support rod 600 is opened on the fixing frame 700. When the support rod 600 is rotated to the width direction of the main body 100, the fixing pin 800 is inserted into the fixing hole 620 and the circular groove 740, thereby fixing the support rod 600.

[0057] In the embodiment of the present application, the support rod 600 and the fixing frame 700 are arranged between the sliding member 200 and the rotating member 300, so that when the protective net is deployed for use through the support rod 600, the movement of the two ends of the main body 100 will not be affected.

[0058] In general, the rotating part 300 and the support rod 600 of the ship ladder can rotate relative to the main body 100, so that when the ship ladder needs to be stored, the rotating part 300 and the support rod 600 can be folded onto the main body 100, and the protective net can be removed from the support rod 600 for separate storage, or it can be folded onto the main body 100 together with the support rod 600, thereby improving the storage capacity of the ship ladder.
