Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ship protection technology, and more specifically, relates to a tugboat bow and stern bumper structure. Background Technology
[0002] Tugs need to be equipped with fenders at the bow and stern to prevent damage to the hull in the event of a collision.
[0003] Existing fenders are mainly secured by chains. To facilitate the securing and winding of the chains, buckles need to be fixed on the bow and stern, which is cumbersome and costly.
[0004] At the same time, when the fenders collide, the chains will also collide and squeeze the hull. The chains can easily scratch the paint on the hull. Without the protection of paint, the hull will rust and cause damage to the hull. Therefore, if chains are used to fix the fenders, the paint will need to be touched up frequently, which will cause trouble for the maintenance of the hull. Utility Model Content
[0005] The main purpose of this utility model is to provide a tugboat bow and stern fender structure, which uses ropes to fix the tires without scratching the paint on the hull.
[0006] According to a first aspect of the present invention, a tugboat bow and stern bumper structure is provided, comprising a plurality of tires, hooks and ropes, wherein the hooks are fixed on the bow and stern of the tugboat, and the ropes pass through the tires and hook onto the hooks to press the tires firmly against the bow and stern of the tugboat.
[0007] In the aforementioned tugboat bow and stern bumper structure, the rope is provided with multiple loops, which are hooked onto the hook.
[0008] In the above-mentioned tugboat bow and stern bumper structure, the hook includes a first hook body and a second hook body. The first hook body includes a first vertical rod, a first upper bend and a first lower bend. The first upper bend and the first lower bend are respectively fixed to the upper and lower ends of the first vertical rod, and a first notch is formed between the first upper bend and the first lower bend.
[0009] The second hook body includes a second vertical rod, a second upper bend and a second lower bend, the second upper bend and the second lower bend are respectively fixed to the upper and lower ends of the second vertical rod, and a second notch is formed between the second upper bend and the second lower bend;
[0010] The first upper bend is higher than the second upper bend, the second upper bend is higher than the first lower bend, the first notch and the second notch are both open in a direction away from the tire, and the ring is fitted onto the first hook and the second hook through the first notch and the second notch.
[0011] In the above-described tugboat bow and stern bumper structure, the first vertical bar is located on the side of the second vertical bar away from the tire.
[0012] In the aforementioned tugboat bow and stern bumper structure, the first hook and the second hook are fixed together by welding.
[0013] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:
[0014] In this invention, a rope is used to secure the tire. The rope is made of a flexible material, so even if the rope rubs against the hull, it will not scratch the paint on the hull. Furthermore, the rope does not need to be secured with a buckle; it can be hooked with a hook, allowing the rope to be wrapped around the bow and stern of the tugboat, which is more convenient and lower in cost.

[0020] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0021] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.
[0022] Reference Figures 1 to 2 As shown, a tugboat bow and stern bumper structure includes multiple tires 1, hooks 2, and ropes 3. The hooks 2 are fixed on the bow and stern of the tugboat, and the ropes 3 pass through the tires 1 and hook onto the hooks 2 to press the tires 1 firmly against the bow and stern of the tugboat.
[0023] The tire 1 is secured by a rope 3. The rope 3 is made of a flexible material, so even if the rope 3 rubs against the hull, it will not scratch the paint of the hull. Moreover, the rope 3 does not need to be secured with a buckle. The hook 2 can be used to hook the rope 3, so that the rope 3 can be wrapped around the bow and stern of the tugboat, which is more convenient and lower in cost.
[0024] In this embodiment, the rope 3 is provided with multiple loops 31, which are hooked onto the hook 2. The loops 31 facilitate the rope 3 to be hooked onto the hook 2 without the rope 3 needing to wrap around the hook 2, thus reducing the difficulty of arranging the rope 3.
[0025] In this embodiment, the hook 2 includes a first hook body 21 and a second hook body 22. The first hook body 21 includes a first vertical rod 211, a first upper bend 212 and a first lower bend 213. The first upper bend 212 and the first lower bend 213 are respectively fixed to the upper and lower ends of the first vertical rod 211, and a first notch is formed between the first upper bend 212 and the first lower bend 213.
[0026] The second hook 22 includes a second vertical rod 221, a second upper bend 222 and a second lower bend 223. The second upper bend 222 and the second lower bend 223 are respectively fixed to the upper and lower ends of the second vertical rod 221, and a second notch is formed between the second upper bend 222 and the second lower bend 223.
[0027] The first upper bend 212 is higher than the second upper bend 222, the second upper bend 222 is higher than the first lower bend 213, the first notch and the second notch are both open in the direction away from the tire 1, and the ring 31 is fitted onto the first hook 21 and the second hook 22 through the first notch and the second notch.
[0028] If the ring 31 is hooked onto a single hook body, the single hook body will be subjected to a large force, and the contact area between the ring 31 and the hook body will be small, making the ring 31 more prone to damage. Therefore, a hook 2 consists of two hook bodies, and the ring 31 will hook onto the first hook body 21 and the second hook body 22 simultaneously, increasing the contact area between the ring 31 and the hook 2. At the same time, the first hook body 21 and the second hook body 22 are slightly offset in the vertical direction. When the ring 31 is hooked onto the hook 2, it will be located between the second upper bend 222 and the first lower bend 213, thereby limiting the position of the ring 31 and preventing the ring 31 from sliding, thus having an anti-detachment function.
[0029] Preferably, the first vertical rod 211 is located on the side of the second vertical rod 221 away from the tire 1. In this way, the first hook 21 and the second hook 22 are also slightly offset in the horizontal direction, and the second upper bend 222 is closer to the first vertical rod 211, so that the ring 31 can be restricted between the first upper bend 212 and the first vertical rod 211, further preventing it from falling off.
[0030] In this embodiment, the hook 2 is welded to the bow and stern of the tugboat. Specifically, the first lower bend 213 and the second lower bend 223 are welded to the bow and stern of the tugboat. At the same time, in order to improve the strength of the hook 2, the first vertical bar 211 and the second vertical bar 221 are welded and fixed, thereby fixing the first hook body 21 and the second hook body 22 together.
[0031] Of course, in practice, appropriate pads can be installed on the bow and stern of the tugboat for welding and fixing the first hook body 21 and the second hook body 22.
[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
