Description

Technical Field

[0001] The present application relates to the technical field of dock facilities, and in particular to a dock anti-collision device. Background Art

[0002] Ship transportation is an important mode of transportation because of its low cost advantage. Ships usually need to berth at docks to load and unload cargo. When a ship is berthed, the ship will sway under the action of waves and wind, which can easily cause the side of the ship to hit the dock. At the same time, the ship is also prone to hit the dock when berthing, causing damage to the dock or the side of the ship. For this reason, people think of fixing waste tires on one side of the dock and using waste tires as buffer pads to reduce the impact of the side of the ship on the dock. For example, a Chinese patent with application number 202021361426.7 discloses a collision-proof tire fixing structure for ships, which limits the tire by tying knots on the fixing rope. In actual use, the rope knot is small and can easily pass through the rope threading hole when pushed by the ship, thereby losing the ability to limit the tire. For this reason, people have designed a new limiting structure. For example, Chinese patent application number 202321594807.3 discloses a suspension for connecting a rubber fender. The suspension is T-shaped, and a sleeve end, a first connecting block, and a first arm end and a second arm end extend from the central intersection of the T-shape. Although this solution can stably fix the tire through the suspension, when the waste tire is damaged, this solution cannot quickly remove the suspension from the tire, and the tire needs to be cut, which is cumbersome. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a dock anti-collision device, which limits the tire by using a limiting plate and opens a long strip through hole in the tire. The limiting plate can pass through the through hole at a specific angle, thereby facilitating the replacement of the tire.

[0004] This application is implemented through the following technical solutions:

[0005] The present application proposes a dock anti-collision device, comprising: waste tires, a first chain, a second chain, and a limiting plate. The waste tires are arranged in a rectangular array, the waste tires are connected longitudinally by the first chain, and the waste tires are connected transversely by the second chain. The limiting plates are respectively connected in series on the first chain and the second chain, and the limiting plates are closely attached to the inner side of the waste tires; the waste tires are provided with through holes, and the first chain and the second chain pass through the through holes; the through holes are long strips, the length of the through holes is greater than the width of the limiting plates, and the middle of the through holes is circular.

[0006] Furthermore, the long direction of the through hole is parallel to the circumferential direction of the waste tire, and the limiting plate is parallel to the long direction of the through hole in a natural state.

[0007] Furthermore, the limiting plate is arc-shaped, the curvature of the limiting plate fits the inner wall of the waste tire, connecting rings are provided on both sides of the limiting plate, and the limiting plate is connected to the first chain or the second chain through the connecting rings.

[0008] Furthermore, the ends of the first chain and the second chain are provided with fixing plates, and the ends of the first chain and the second chain are fixed to the side of the dock through the fixing plates.

[0009] Furthermore, the fixing plate is fixed to the side of the wharf by bolts, and the bolts are pre-embedded in the side of the wharf.

[0010] Furthermore, the width of the fixing plate is smaller than the length of the through hole.

[0011] The beneficial effects of the present application are as follows: by arranging a flat limiting plate and a fixing plate on the chain, the limiting plate and the fixing plate can pass through the through hole after adjusting the angles, so that the chain is conveniently separated from the waste tire, and the damaged waste tire is conveniently replaced. The waste tire is fixed by the limiting plate on the chain, so that the waste tire is kept on the side of the dock, and when the ship approaches, the waste tire can play a buffering role to protect the ship's side and the dock.

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] In addition, the descriptions of "first", "second", etc. in this application are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0021] like Figures 1 to 5 As shown, an embodiment of the utility model provides a dock anti-collision device, comprising: a waste tire 1, a first chain 2, a second chain 3, and a limiting plate 4. The waste tires 1 are arranged in a rectangular array, the waste tires 1 are connected longitudinally by the first chain 2, and the waste tires 1 are connected transversely by the second chain 3. The limiting plates 4 are respectively connected in series to the first chain 2 and the second chain 3, and the limiting plates 4 are closely attached to the inner side of the waste tire 1; a through hole 5 is provided on the waste tire 1, and the first chain 2 and the second chain 3 pass through the through hole 5; the through hole 5 is in the shape of a long strip, the length of the through hole 5 is greater than the width of the limiting plate 4, and the middle part of the through hole 5 is circular.

[0022] When making the anti-collision device, firstly, a through hole 5 is opened on the waste tire 1, and then the angles of the fixing plate 7 and the limiting plate 4 are adjusted. Since the length of the through hole 5 is greater than the width of the limiting plate 4, the limiting plate can pass through the through hole 5 along its long direction. Since the connecting rings 6 are arranged at both ends of the limiting plate 4, the width thereof will be slightly larger. Therefore, the middle part of the through hole 5 is set to be circular to facilitate the passing of the limiting plate 4. After the waste tire 1 is connected by the first chain 2 and the second chain 3, the fixing plate 7 is fixed to the side of the dock. Since the waste tire 1 is fixed by the chain and the limiting plate 4, the waste tire 1 is kept at the side of the dock. When a ship approaches, the waste tire 1 can play a buffering role to protect the ship's side and the dock.

[0023] Due to ship collision, tearing, aging and other reasons, the waste tire 1 may be damaged. When the waste tire 1 needs to be replaced, the bolts on it are loosened, and then the limiting plate 4 and the fixing plate 7 are passed through the through hole 5 in the same way, so as to separate the waste tire 1 from the chain, so as to facilitate the replacement of the intact waste tire 1.

[0024] In a preferred embodiment, Figure 2 , Figure 3 As shown, the long direction of the through hole 5 is parallel to the circumferential direction of the waste tire 1, and the limiting plate 4 is parallel to the long direction of the through hole 5 in a natural state. When fixing the waste tire 1, the limiting plate 4 is pulled by the chain so that it fits the inner wall of the waste tire 1. Therefore, without human intervention, the limiting plate 4 can hardly pass through the through hole 5, thereby ensuring that the first chain 2 and the second chain 3 effectively fix the waste tire 1.

[0025] Specifically, Figure 5 As shown, the limiting plate 4 is arc-shaped, and the curvature of the limiting plate 4 fits with the inner wall of the waste tire 1. Connecting rings 6 are provided on both sides of the limiting plate 4. The limiting plate 4 is connected to the first chain 2 or the second chain 3 through the connecting rings 6. Under the pulling of the chain, the limiting plate 4 fits with the inner wall of the waste tire 1, thereby limiting the waste tire 1.

[0026] Preferably, a fixing plate 7 is provided at the ends of the first chain 2 and the second chain 3, and the ends of the first chain 2 and the second chain 3 are fixed to the side of the dock through the fixing plate 7, thereby providing a support point and fixing the entire anti-collision device to the side of the dock. When a ship approaches, the waste tire 1 can play a buffering role to protect the ship's side and the dock.

[0027] In a specific embodiment, the fixing plate 7 is fixed to the side of the wharf by bolts, and the bolts are pre-buried in the side of the wharf, so that the fixing plate 7 can be removed to facilitate replacement of the waste tire 1 when necessary.

[0028] Preferably, the width of the fixing plate 7 is smaller than the length of the through hole 5 , so that the fixing plate 7 can pass through the through hole 5 .

[0029] Preferably, if Figure 5 As shown, since the waste tire 1 is made of vulcanized rubber and can be deformed, when the limiting plate 4 passes through the through hole 5, if the chain or the limiting plate 4 is stuck, the limiting plate 4 can be forced to pass through the through hole 5 by hammering.

[0030] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
