Abstract
Description
Technical Field
[0001] This utility model belongs to the field of anti-collision technology for coal carrier berthing, and particularly relates to an anti-collision structure for coal carrier berthing in ports. Background Technology
[0002] A coal carrier is a vessel used to transport coal. The carrying capacity of a coal carrier varies depending on its cargo size. Large cargo ships are typically used for larger loads, while smaller coal carriers tend to have smaller loads. However, unlike large cargo ships, smaller coal carriers are often more maneuverable and more commonly used in practice, especially when coal orders are smaller. Smaller coal carriers often have advantages such as shorter transport cycles and higher efficiency.
[0003] When coal carriers arrive at the port with their coal, they often moor near the shore to facilitate unloading (the port docks are equipped with conveyor belts for transporting materials).
[0004] In actual operation, when coal carriers are moored, one side of the carrier is close to the edge of the dock. Therefore, to prevent collisions during mooring, discarded tires are often placed as cushioning pads along the edge of the dock. When the coal carrier docks, it may impact or scrape against the tires. These rubber tires provide protection for the coal carrier during operation.
[0005] However, in actual operation, due to the large friction area between the tires and the sides of the coal carrier, frequent scrapes cause the paint on the sides of the coal carrier to peel off. The paint on the sides of the coal carrier is an anti-corrosion paint, mainly used to protect the hull structure from rust over the years.
[0006] Meanwhile, because the coal carrier still has a certain amount of kinetic energy while it is docked, the distance that the coal carrier moves and scrapes against the tire pads is relatively long, resulting in the tire pads scraping a large area of the protective paint on the surface of the coal carrier.
[0007] In view of the above-mentioned technical defects, it is currently difficult to adopt a protective device that can conveniently brake the coal carrier while it is docked, and also prevent the protective paint from being scratched and peeled off over a large area due to collisions or scrapes. Utility Model Content
[0008] Based on the above background, the purpose of this utility model is to provide a collision protection structure for berthing coal transport ships in ports.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] A collision avoidance structure for berthing coal carriers in ports, including a collision damping mechanism that works in conjunction with the coal carrier;
[0011] The anti-collision damping mechanism includes an abutment wheel, with axles fixedly connected to the top and bottom of the abutment wheel, and a damping structure installed on the axles;
[0012] The damping structure includes a damping wheel fixedly mounted on the axle, and the damping wheel is limited by a housing; several damping structures are provided between the inner wall of the housing and the damping wheel, which increase the rotational resistance of the counter-rotating wheel and reduce the speed of the coal transport ship.
[0013] Preferably, a buffer support structure is fixedly connected between the shells, and the buffer support structure is fixedly installed on the edge of the dock where the coal carrier is moored.
[0014] Preferably, the buffer support structure includes a U-shaped support fixedly connected between the housings, and spring telescopic structures are fixedly connected to the upper and lower ends of the U-shaped support respectively;
[0015] The spring telescopic structures are fixedly connected to a mounting base, which is fixedly installed on the edge of the dock.
[0016] Preferably, the spring telescopic structure includes a slide rod fixedly connected to the U-shaped bracket, the slide rod being slidably connected to a sliding sleeve, and the sliding sleeve being fixedly connected to the mounting base;
[0017] A spring is fitted onto the sliding rod, and the two ends of the spring are fixedly connected to the U-shaped bracket and the sliding sleeve, respectively.
[0018] Preferably, the damping structure includes a curved protrusion integrally formed on the damping wheel;
[0019] The inner wall of the housing is equipped with a damping element that engages with the curved protrusion. During the rotation of the damping wheel, the curved protrusion and the damping element work together to generate a damping force.
[0020] Preferably, the damping element includes a damping rod, the outer end of which is located between adjacent curved protrusions;
[0021] The damping rod is slidably connected to a damping sleeve, which is fixedly connected to the inner wall of the housing.
[0022] A damping spring is fixedly connected to the inner end of the damping rod, and the damping spring is fixedly connected inside the damping sleeve.
[0023] Preferably, the outer end of the damping rod is integrally formed with a curved protrusion. During the rotation of the damping wheel, the curved protrusion abuts against the curved protrusion, and after pushing the damping rod to overcome the elastic resistance of the damping spring and retract, the curved protrusion passes over the curved protrusion.
[0024] Preferably, the inner end of the damping rod is fixedly connected to a piston seat, and the damping sleeve has a sliding cavity adapted to the piston seat. The damping spring is fixedly connected to the piston seat and the sliding cavity.
[0025] The damping sleeve has an exhaust port structure.
[0026] Preferably, the damping sleeve is fastened to the inner wall of the housing by mounting bolts.
[0027] This utility model has the following beneficial effects:
[0028] 1. During operation, as the damping wheel rotates, the curved protrusions on it rotate continuously. During this process, multiple curved protrusions repeatedly contact the curved protrusions on adjacent damping rods. Under this resistance, the damping rods overcome the elastic resistance of the damping springs and continuously retract into the damping sleeve, then extend outwards. During the rotation of the damping wheel, multiple damping components work synchronously; specifically, the damping rods on multiple damping components repeatedly extend and retract elastically, generating damping force.
[0029] Therefore, during the above process, the rotational resistance of the contact wheel is very large, and it will not be completely locked. Thus, after the coal ship makes contact, although it still has a certain forward momentum, it can quickly brake to a stop with the cooperation of multiple contact wheels.
[0030] The above method not only achieves braking of the coal transport ship but also prevents damage to the anti-corrosion coating caused by scraping against the ship's paint during braking. Furthermore, the structure also prevents the coal transport ship from colliding with the dock edge during and after berthing.
[0031] 2. During operation, when the coal carrier is moored or stationary, it comes into vertical contact with the entire device. At this time, the spring-loaded structure acts as a buffer, compressing the spring and retracting the sliding rod into the sleeve. This method ensures that when the coal carrier moves laterally due to water waves, it comes into vertical contact with the contact wheel, achieving a buffered vertical movement. This further protects the coal carrier from high-energy collisions. Attached Figure Description

[0042] Example 1
[0043] like Figure 1-5As shown, a collision avoidance structure for berthing coal carriers in a port includes a collision damping mechanism 2 that works in conjunction with the coal carrier. In actual operation, multiple such mechanisms are evenly spaced along the edge of the dock where the coal carrier is moored. When the coal carrier returns and moors near the edge of the dock, it comes into contact with the collision damping mechanism 2. The mechanism's collision avoidance, damping braking, and buffering functions bring the coal carrier to a stop, while simultaneously preventing extensive scraping that could damage the anti-corrosion coating.
[0044] Specifically, the anti-collision damping mechanism 2 includes an abutment wheel 1. In the existing manner, a rubber washer (not shown in the figure) is fixed on the outline of the abutment wheel 1 to achieve elastic contact with the side of the hull of the coal carrier.
[0045] When the coal carrier comes into contact with the contact wheel 1, the contact wheel 1 rotates with damping and simultaneously expands and contracts elastically. This method protects the coal carrier, and because the friction between the contact wheel and the coal carrier is rolling, it is less likely to scratch or damage the anti-corrosion coating on the coal carrier.
[0046] Specifically, the top and bottom of the abutment wheel 1 are respectively fixedly connected to axle 22, and a damping structure is installed on axle 22; the damping structure includes a damping wheel 23 fixedly installed on axle 22, and the damping wheel 23 is limited by a housing 21.
[0047] The damping wheel 23 is located inside the housing 21, which has a disc-shaped structure with an internal cavity. The axle 22 passes through the center of the housing 21, and therefore, in the conventional manner, a bearing adapted to the axle 22 is installed at the through-hole position of the housing 21. At the same time, the end of the axle 22 located inside the housing 21 is rotatably connected to the inner wall of the housing 21.
[0048] During operation, when a coal carrier docks and touches the abutment wheel 1, it will continue to move a certain distance due to its kinetic energy, thus repeatedly colliding with the abutment wheel 1. The abutment wheel 1 rotates under damping. Because multiple anti-collision structures are arranged along the edge of the dock where the coal carrier is moored, the coal carrier experiences significant resistance to movement and is continuously braked due to the combined effect of these multiple damped rotating abutment wheels 1.
[0049] Specifically, the rotating abutment wheel 1 synchronously drives the damping wheel 23 to rotate, and several damping structures are provided between the inner wall of the shell 21 and the damping wheel 23. The damping structures increase the rotational resistance of the abutment wheel 1, thereby slowing down the coal transport ship.
[0050] Example 2
[0051] like Figure 1-5As shown, based on the structure of Embodiment 1, each of the above damping structures includes a curved protrusion 24 integrally formed on the damping wheel 23 (the transverse cross-sectional shape of the curved protrusion 24 is semi-circular, and its height corresponds to the thickness of the damping wheel 23). A damping gap is formed between adjacent curved protrusions 24.
[0052] Correspondingly, a damping element 25 that cooperates with the curved protrusion 24 is installed on the inner wall of the housing 21. During the rotation of the damping wheel 23, the curved protrusion 24 and the damping element 25 cooperate to form a damping force.
[0053] Specifically, the damping element 25 includes a damping rod 251, the outer end of which is located between adjacent curved protrusions 24; the damping rod 251 is slidably connected to a damping sleeve 252, which is fixedly connected to the inner wall of the housing 21.
[0054] Specifically, a damping spring 253 is fixedly connected to the inner end of the damping rod 251, and the damping spring 253 is fixedly connected inside the damping sleeve 252 (the damping sleeve 252 is fastened to the inner wall of the housing 21 by mounting bolts). The outer end of the damping rod 251 is integrally formed with a curved protrusion 2511 (the curved protrusion 2511 extends into the damping gap). During the rotation of the damping wheel 23, the curved protrusion 24 abuts against the curved protrusion 2511, pushing the damping rod 251 to overcome the elastic resistance of the damping spring 253 and retract. After that, the curved protrusion 24 passes over the curved protrusion 2511.
[0055] Meanwhile, the inner end of the damping rod 251 is fixedly connected to the piston seat 2531 (during the extension and retraction process, the piston seat 2531 slides in the sliding cavity), the damping sleeve 252 is provided with a sliding cavity adapted to the piston seat, and the damping spring 253 is fixedly connected to the piston seat and the sliding cavity; the damping sleeve 252 is provided with an exhaust through hole structure 2521 (opened on the damping sleeve 252, connecting to the sliding cavity).
[0056] Similarly, the housing 21 also has a matching through hole. During operation, when the rotating damping wheel 23 rotates, the curved protrusions 24 on the damping wheel 23 rotate continuously. During this process, multiple curved protrusions 24 continuously touch the curved protrusions 2511 on the adjacent damping rods 251. Under the pushing force of the contact, the damping rods 251 overcome the elastic resistance of the damping springs 253 and continuously retract into the damping sleeves 252, and then extend out.
[0057] Therefore, during the rotation of the damping wheel 23, multiple damping components 25 work synchronously. Specifically, the damping rods 251 on the multiple damping components 25 repeatedly extend and retract elastically to form a damping force.
[0058] Therefore, during the above process, the rotational resistance of the contact wheel 1 is very large and it will not be completely locked. Thus, after the coal ship makes contact, although the coal ship still has a certain forward momentum, it is quickly braked to a stop with the cooperation of multiple contact wheels 1.
[0059] The above method not only achieves braking of the coal transport ship but also prevents damage to the anti-corrosion coating caused by scraping against the ship's paint during braking. Furthermore, the structure also prevents the coal transport ship from colliding with the dock edge during and after berthing.
[0060] Example 3
[0061] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, a buffer support structure 3 is fixedly connected between the shells 21, and the buffer support structure 3 is fixedly installed on the edge of the dock where the coal carrier is moored.
[0062] The buffer support structure 3 is used to fix the shell 21 at the top and bottom positions, and at the same time form a buffer.
[0063] Specifically, the buffer support structure 3 includes a U-shaped support 31 (fixed by bolts) fixedly connected between the housing 21, and spring telescopic structures are fixedly connected to the upper and lower ends of the U-shaped support 31 respectively.
[0064] Specifically, a mounting base 34 is fixedly connected between the spring telescopic structures, and the mounting base 34 is fixedly installed on the edge of the dock. The spring telescopic structure includes a slide rod fixedly connected to a U-shaped bracket 31, a sliding sleeve 33 slidably connected to the slide rod, and the sliding sleeve 33 is fixedly connected to the mounting base 34; a spring 32 is sleeved on the slide rod, and the two ends of the spring 32 are respectively fixedly connected to the U-shaped bracket 31 and the sliding sleeve 33 (the end of the spring 32 is fixed at the edge of the opening of the sliding sleeve 33).
[0065] During operation, when the coal carrier is moored or stationary, it comes into vertical contact with the entire device. At this time, the spring extension structure acts as a buffer, compressing the spring 32 and retracting the sliding rod into the sliding sleeve 33. This method ensures that, during lateral movement of the coal carrier propelled by waves, the carrier comes into vertical contact with the contact wheel 1, achieving a buffered vertical movement. This further protects the coal carrier from high-energy collisions.
[0066] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
