Description

Technical Field

[0001] The utility model relates to the technical field of ship components, in particular to a docking structure for ship passage equipment. Background Art

[0002] Ship passage equipment includes hatch covers, roll-on / roll-off equipment, etc. When in use, they all need to be opened through a liquid-electric system to achieve the task goal. When the passage equipment is opened to the stowed state, it needs to be fixed to prevent the passage equipment from retracting and affecting the task goal, and to prevent major cargo damage or personal life safety. This kind of fixation is temporary. When the target task is completed, the fixed state needs to be released, and the passage equipment is operated through the liquid-electric system to return to the closed state. Therefore, the fixation system for the stowed state of the passage equipment needs to have functions such as buffering, stopping, fixing, and releasing fixation.

[0003] Currently, conventional fixation solutions often include multiple individual functional modules, namely a stopping device with buffering and stopping functions, a mechanical fixation device with a fixing function, and manual fixation release operations. This solution often requires a large amount of manual operation. Once a manual operation error or omission occurs, it will lead to the failure of the fixation task and cause major cargo damage or personal life safety. In addition, the stowed position of the passage equipment is often far from the area reachable by manpower. To fix the passage equipment, remote liquid-electric operation or a large number of pulley systems need to be equipped, greatly increasing the manufacturing cost. Summary of the Invention

Detailed Embodiments

[0043] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some, rather than all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0044] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0045] The docking structure for ship channel equipment provided by the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0046] like Figures 1 to 7 As shown, an embodiment of the present application provides a docking structure for ship channel equipment, including a mounting base 100 fixedly connected to an external mounting frame and a driven connector 200 fixedly connected to the ship channel equipment, a cavity 140 is provided on the mounting base 100, and the driven connector 200 includes a connecting shaft 220 that can be slidably connected to the cavity.

[0047] The connecting shaft 220 includes an optical axis section 221 and a conical section 222 that can be slidably connected to the cavity 140. The end of the conical section 222 with a larger diameter is connected to the end of the optical axis section 221 away from the ship channel equipment and has a diameter larger than the diameter of the optical axis section 221. The connecting part between the optical axis section 221 and the conical section 222 is rounded.

[0048] A permanent magnet 600 is fixedly provided in the cavity 140 and can be attracted to the end of the optical axis section 221 away from the ship channel equipment, and a plurality of limit assemblies 400 that can be engaged with the outer peripheral surface of the connecting shaft 220 are fixedly provided on the inner wall of the cavity 140. The limit assemblies 400 include locking members 430 that can elastically expand and contract along the radial direction of the connecting shaft 220.

[0049] Among them, the locking member 430 can abut against the outer peripheral surface of the conical section 222 when not subjected to the elastic force. When the connecting shaft 220 and the permanent magnet 600 are in the attracted state, the locking member 430 can abut against the side end of the conical section 222 close to the optical axis section 221 under the action of the elastic force applied to it to limit the displacement of the connecting shaft 220 toward the side away from the permanent magnet 600.

[0050] It can be understood that, in the initial state, the lock 430 is not subjected to elastic force; when the ship channel device moves to the point where the connecting shaft 220 extends into the cavity 140, the lock 430 abuts against the outer peripheral surface of the conical section 222 and moves axially along the conical section 222, and at the same time, the lock 430 moves to the side away from the central axis of the conical section 222 and accumulates elastic potential energy; when the connecting shaft 220 moves to the point where the end away from the ship channel device is attracted by the permanent magnet 600, the lock 430 is located at the corresponding position of the optical axis section 221 and abuts against the outer peripheral surface of the optical axis section 221 and the conical section 222 close to the optical axis under the action of elastic force. One end of the shaft section 221 is used to limit the displacement of the driven connector 200 to the side away from the permanent magnet 600, that is, to limit the unpowered withdrawal of the ship channel equipment; when the driven connector 200 is released from the relative fixation with the mounting base 100, the ship channel equipment is operated to allow the driven connector 200 to generate additional pulling force, and the driven connector 200 overcomes the suction force of the permanent magnet 600 under the action of the pulling force, and the locking member 430 is reset under the guidance of the fillet between the optical axis section 221 and the conical section 222, and the driven connector 200 is detached from the cavity 140 to complete the release of the fixation of the ship channel equipment.

[0051] In an embodiment of the present application, the above-mentioned docking structure for ship channel equipment is adopted, and the positioning of the ship channel equipment is achieved by attracting the driven connector 200 through the permanent magnet 600, and the limiting of the driven connector 200 is achieved through the limiting assembly 400. It can not only realize the stopping and fixing functions when the ship channel equipment is opened and the fixing release function when the closing operation is started, but also has a simple structure, occupies little space, and does not require additional power actuators, which greatly improves the docking efficiency of the ship channel equipment.

[0052] In a preferred embodiment, Figures 1 to 3 , Figure 5 , Figure 7 As shown, the driven connecting member 200 further includes a connecting component 210 fixedly disposed on one end of the connecting shaft 220 close to the ship passage device and fixedly connected to the ship passage device.

[0053] In a preferred embodiment, Figures 1 to 6 As shown, the mounting base 100 includes a base plate 110 , a limiting portion 120 fixedly disposed on the base plate 110 , and a transition flange cylinder 130 fixedly disposed on the limiting portion 120 .

[0054] The cavity 140 is disposed through the limiting portion 120 and the transition flange cylinder 130 , the limiting assembly 400 is fixedly disposed on the limiting portion 120 , and the permanent magnet 600 is located at a corresponding position of the transition flange cylinder 130 .

[0055] In a preferred embodiment, Figure 4 , Figure 5As shown, the cavity 140 includes a lock cavity 141 passing through the limiting portion 120 and a receiving cavity 142 passing through the transition flange cylinder 130 and communicating with the lock cavity 141.

[0056] Among them, a plurality of limiting components 400 are arranged in an annular array on the inner wall of the lock cavity 141 with respect to the central axis of the lock cavity 141.

[0057] In a preferred embodiment, as Figures 1 to 3 , Figure 5 shown, a cover plate 300 is fixedly provided at one end of the transition flange cylinder 130 away from the limiting portion 120, and a permanent magnet 600 is located in the receiving cavity 142 and fixedly connected to one end of the cover plate 300 close to the limiting portion 120.

[0058] In a preferred embodiment, as Figure 3 , Figure 5 , Figure 6 shown, a first buffer pad 510 capable of abutting against one end of the driven connecting member 200 away from the ship passage device is fixedly provided at one end of the permanent magnet 600 away from the cover plate 300.

[0059] It can be understood that when the ship passage device moves to insert the connecting shaft 220 into the cavity 140, the first buffer pad 510 can buffer the connecting shaft 220, thereby reducing the vibration during the docking of the ship passage device and improving the service life and working stability of the docking structure.

[0060] In a preferred embodiment, as Figure 3 , Figure 5 , Figure 6 shown, a second buffer pad 520 is fixedly provided at one end of the cover plate 300 close to the limiting portion 120, and the permanent magnet 600 is fixedly arranged at one end of the second buffer pad 520 away from the cover plate 300.

[0061] It can be understood that the buffer effect when the connecting shaft 220 and the permanent magnet 600 are attracted can be further improved through the second buffer pad 520, ensuring the working stability of the docking structure.

[0062] In a preferred embodiment, as Figures 4 to 6 shown, the cover plate 300 is bolted to one end of the transition flange cylinder 130 away from the limiting portion 120, the diameter of the receiving cavity 142 is larger than the diameter of the lock cavity 141, and one end of the first buffer pad 510 away from the permanent magnet 600 abuts against the inner wall of the receiving cavity 142 close to the lock cavity 141.

[0063] It is understandable that when the cover plate 300 is installed on the transition flange cylinder 130, the first buffer pad 510 abuts against the inner wall of the accommodating cavity 142 close to the locking cavity 141, so that the position stability of the first buffer pad 510, the permanent magnet 600 and the second buffer pad 520 can be ensured when the connecting shaft 220 and the permanent magnet 600 are attracted.

[0064] In a preferred embodiment, Figure 4 As shown, a plurality of embedding holes 150 are formed between the inner wall of the locking cavity 141 and the outer surface of the limiting portion 120 .

[0065] The plurality of embedding holes 150 are arranged in a circular array about the central axis of the locking cavity 141 , and the plurality of limiting components 400 are respectively fixedly disposed in the plurality of embedding holes 150 .

[0066] In a preferred embodiment, Figure 4 As shown, the central axis of the embedding hole 150 extends radially along the central axis of the locking cavity 141 .

[0067] In a preferred embodiment, Figure 5 , Figure 6 As shown, the limiting assembly 400 further includes an embedded column 410 fixedly disposed in the embedded hole 150 , and a guide hole 420 is provided at one end of the embedded column 410 close to the central axis of the lock cavity 141 , and a locking member 430 is slidably disposed in the guide hole 420 .

[0068] An elastic member 440 is fixedly disposed between one end of the locking member 430 away from the central axis of the locking cavity 141 and an inner wall of the guide hole 420 away from the central axis of the locking cavity 141 .

[0069] It can be understood that, in the initial state, the elastic member 440 is not compressed; when the connecting shaft 220 extends into the cavity 140, the locking member 430 abuts against the outer peripheral surface of the conical section 222, and the elastic member 440 is compressed; when the connecting shaft 220 and the permanent magnet 600 are attracted, the locking member 430 is reset under the elastic force of the elastic member 440, thereby achieving abutment with the end of the conical section 222 close to the optical axis section 221, that is, achieving the position limitation of the driven connecting member 200 to the side away from the permanent magnet 600.

[0070] In a preferred embodiment, the locking element 430 is specifically configured as a ball.

[0071] It is understandable that the setting form of the locking element 430 is not limited to the above-mentioned one. For example, it can also be set as a cylinder, a prism, etc., as long as it can achieve the interference limit of the connecting shaft 220, which will not be elaborated here.

[0072] In a preferred embodiment, the elastic member 440 is specifically configured as one of a spring, elastic rubber, and a spring.

[0073] It can be understood that the setting form of the elastic member 440 is not limited to the above structure, as long as it can provide a reset elastic force for the locking member 430, which will not be elaborated here.

[0074] In a preferred embodiment, as Figure 5 , Figure 6 shown, the stud 410 is threadedly connected to the socket 150, and a torsion groove is provided at one end of the stud 410 away from the cavity 140.

[0075] In the embodiment of the present application, by adopting the above docking structure for ship passage equipment, an operator can rotate and install the limiting component 400 in the socket 150 by embedding a tool into the torsion groove. Since the stud 410 is threadedly connected to the socket 150, the staff can rotate and adjust the position of the limiting component 400 in the radial direction of the central axis of the cavity 140, that is, adjust the initial position of the locking member 430 to adapt to the specification of the connecting shaft 220, so as to ensure the limiting stability of the locking member 430 to the connecting shaft 220 when the driven connecting member 200 is attracted to the permanent magnet 600.

[0076] It should be noted that in this article, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
