Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, specifically to a marine liquid cargo replenishment and transportation device. Background Technology

[0002] At sea replenishment refers to the replenishment technology that transfers materials while a ship is sailing or anchored using specialized equipment. It mainly includes four types: lateral replenishment, longitudinal replenishment, anchor replenishment, and vertical replenishment. Among them, lateral replenishment adopts a two-ship parallel synchronous sailing mode and realizes bidirectional transportation of dry and liquid cargo through a cable bridge. Although it is difficult to operate, it has high transportation efficiency and large transportation capacity, so it is used frequently.

[0003] During lateral replenishment at sea, to achieve the structural strength of the pipeline for liquid cargo transportation and the operational effect of stable output from multiple pipelines, existing technologies often employ auxiliary frames reinforced by welding several pipeline joints. For example, the patent application with application number 201610334467.9 discloses in its description that "the transition pipeline is arranged parallel to the direction of the connecting support plate, and the two sides of the transition pipeline are welded to the corresponding connecting support plate; multiple parallel connecting crossbars are provided between the same end of the two connecting support plates, and the connecting crossbars are welded to the top or bottom of the transition pipeline." However, the straight plate structure of the frame and the transition pipeline have a line-surface contact, resulting in a small contact area and high welding difficulty. Furthermore, the frame can only provide direct pressure resistance to the impacts suffered by the pipeline during use, which increases the likelihood of cracks appearing at the connection between the pipeline and the frame due to the high compressive strength of the pipeline, thus affecting the overall replenishment operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a marine liquid cargo replenishment and transportation device, which solves the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a marine liquid cargo replenishment and transportation device, including a frame, with a plurality of transition pipes arranged inside the top of the frame, and through-type clearance grooves opened on both sides of the frame. Two curved clamps are fitted inside the clearance grooves to clamp the surfaces of the transition pipes. The curved clamps are fixedly installed with the transition pipes and the frame by welding. The top and bottom of the curved clamps pass through their respective clearance grooves and extend to the outside of the frame. A reinforcing rod is fitted between the two curved clamps on the left and right sides, and clamping nuts are threaded to the surfaces of both ends of the reinforcing rod.

[0006] Preferably, the middle part of the curved clamp is set as an arc structure, and the inner wall of the arc structure is fitted and connected to the surface of the corresponding transition pipe, providing sufficient connection area for subsequent welding and fixing, reducing welding difficulty while also significantly improving the assembly and connection strength between the transition pipe and the frame.

[0007] Preferably, an assembly hole is provided on the inner side of one end of the clamping nut, and a rubber plug is provided in the assembly hole. The rubber plug can be nested and sealed with the fitting of the clamping nut and the end of the reinforcing rod to prevent external moisture from entering the connection gap between the clamping nut and the reinforcing rod and causing corrosion, thereby extending the service life of the clamping nut and the reinforcing rod and reducing the cost of use.

[0008] Preferably, a buffer structure is provided on the outer side of the middle part of the reinforcing rod, and the buffer structure includes a spring. The spring is fitted on the outer side of the middle part of the reinforcing rod, and damping rings are fixed at both ends of the spring. The ends of the damping rings are in close contact with the inner wall of the frame. The buffer structure can dampen and buffer the impact on the frame and its related structures based on the frame structure, thereby improving the compressive strength and service life of the overall device.

[0009] Preferably, the surface of the clamping nut can make active contact with the surface of the frame, thereby providing working conditions for further strengthening the structural strength of the frame without interfering with the rotation and locking operation of the clamping nut. Furthermore, the clamping nut and the frame can be welded and fixed together, thereby making the assembly formed by the reinforcing rod and the two clamping nuts integrally connected with the frame, further improving the structural strength and subsequent compressive strength of the frame.

[0010] Preferably, metal washers are snapped onto the outer sides of both ends of the reinforcing rod, and the metal washers are in close contact with the end face of the other end of the clamping nut. The metal washers can serve as structural conditions for the expansion of the clamping nut's pressing surface, thereby improving the clamping nut's pressing and limiting strength on the curved clamping plate and the connection strength of the two structures during the threaded connection between the clamping nut and the reinforcing rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model uses multiple curved clamps to assemble with a frame and a transition pipe. After the two curved clamps initially clamp and fix the transition pipe within the frame, the curved clamps and the transition pipe, as well as the curved clamps and the frame, are welded and fixed in a face-to-face contact state. This not only significantly improves the connection strength of the transition pipe, frame, and curved clamps, but also ensures sufficient welding area during the welding process, reducing assembly difficulty.

[0013] 2. This utility model forms a multi-functional auxiliary device by setting a reinforcing rod and two clamping nuts associated with the reinforcing rod and a buffer structure. After being assembled with the frame and curved clamping plate, it can further improve the structural strength of the overall device. The spring is synchronously compressed and its two corresponding damping rings are linked in the way of reciprocating deformation of the structure, thereby damping and buffering the energy of the overall device and improving the compressive strength of the overall device during use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 and Figure 4A marine liquid cargo replenishment and transportation device includes a frame 1. Several transition pipes 2 are arranged inside the top of the frame 1, and through-type clearance grooves 3 are opened on both sides of the frame 1. Two curved clamping plates 4 are fitted inside the clearance grooves 3 to clamp the surfaces of the transition pipes 2. The curved clamping plates 4 are fixedly installed with the transition pipes 2 and the frame 1 by welding. The top and bottom of the curved clamping plates 4 pass through their respective clearance grooves 3 and extend to the outside of the frame 1. A reinforcing rod 5 is fitted between the two curved clamping plates 4 that are opposite each other, and clamping nuts 6 are threaded to the surfaces of both ends of the reinforcing rod 5.

[0022] The curved clamp 4 has an arc-shaped structure in the middle, and the inner wall of the arc-shaped structure is in close contact with the surface of the corresponding transition pipe 2, providing sufficient connection area for subsequent welding and fixing, reducing welding difficulty, and also significantly improving the assembly connection strength between the transition pipe 2 and the frame 1.

[0023] In use, multiple curved clamps 4 are assembled in pairs with the transition pipe 2, and the inner walls of the arc-shaped structures in the middle of the two curved clamps 4 are attached to the surface of the transition pipe 2 for initial clamping and fixation. Then, existing welding equipment is used to weld and fix the connection between the transition pipe 2 and the curved clamps 4, and the connection between the curved clamps 4 and the frame 1. Since the connection between the transition pipe 2 and the curved clamps 4, and between the curved clamps 4 and the frame 1, are all in a face-to-face contact state, the composite structure formed by the welding and assembly of the transition pipe 2, the frame 1, and the multiple curved clamps 4 has excellent compressive strength, which meets the connection and assembly requirements in the liquid level replenishment process.

[0024] Next, the curved clamping plate 4 and the transition pipe 2 are assembled again by using the reinforcing rod 5 and the two clamping nuts 6 associated with the reinforcing rod 5 as a reinforcing structure, and further enhancing the structural strength of the overall device and optimizing the compressive strength of the overall device.

[0025] Please see Figure 1 and Figure 4 An assembly hole is provided on the inner side of one end of the clamping nut 6, and a rubber plug 9 is provided in the assembly hole. The rubber plug 9 can be nested and sealed with the fitting part of the clamping nut 6 and the end of the reinforcing rod 5 to prevent external moisture from entering the connection gap between the clamping nut 6 and the reinforcing rod 5 and causing corrosion, thereby extending the service life of the clamping nut 6 and the reinforcing rod 5 and reducing the cost of use.

[0026] Metal washers 10 are snapped onto the outer sides of both ends of the reinforcing rod 5, and the metal washers 10 are in close contact with the end face of the other end of the clamping nut 6. The metal washers 10 can serve as a structural condition for the expansion of the clamping surface of the clamping nut 6, thereby improving the clamping strength of the clamping nut 6 in pressing and limiting the curved clamping plate 4 and the connection strength of the two structures during the threaded connection between the clamping nut 6 and the reinforcing rod 5.

[0027] During use, to prevent moisture from the environment from entering the fitting area between the clamping nut 6 and the end of the reinforcing rod 5 and causing corrosion, a rubber plug 9 is used as a sealing condition to fill and seal the space after the reinforcing rod 5 and the clamping nut 6 are fitted together. This isolates the reinforcing rod 5 from the moisture in the environment, prevents corrosion, and extends the service life of the reinforcing rod 5.

[0028] Please see Figure 1 and Figure 5 A buffer structure is provided on the outer side of the middle part of the reinforcing rod 5, and the buffer structure includes a spring 7. The spring 7 is fitted on the outer side of the middle part of the reinforcing rod 5, and damping rings 8 are fixed at both ends of the spring 7. The ends of the damping rings 8 are in close contact with the inner wall of the frame 1. The buffer structure can dampen and buffer the impact on the frame 1 and its associated structures based on the structure of the frame 1, thereby improving the compressive strength and service life of the overall device.

[0029] When in use, if the device is subjected to impact during subsequent use, the spring 7 is simultaneously compressed and its two corresponding damping rings 8 are linked in a reciprocating deformation manner to dampen and buffer the energy of the device.

[0030] Please see Figure 1 , Figure 2 The surface of the clamping nut 6 can make active contact with the surface of the frame 1, thereby providing working conditions for further strengthening the structural strength of the frame 1 without interfering with the rotational locking operation of the clamping nut 6. The clamping nut 6 and the frame 1 can be welded and fixed, thereby making the assembly formed by the reinforcing rod 5 and the two clamping nuts 6 integrally connected with the frame 1, further improving the structural strength and subsequent compressive strength of the frame 1.

[0031] Working principle: Considering the special needs of subsequent operation in harsh environments, the structural strength of the overall device still needs to be further improved. The combination of the reinforcing rod 5 and the two clamping nuts 6 associated with the reinforcing rod 5 is used as an extension condition. After the clamping nuts 6 are threadedly connected to the reinforcing rod 5, the clamping nuts 6 are then welded and fixed to the frame 1. In this way, the structure of the entire device is set to be fixed connection, which further improves the structural strength of the overall device and thus meets the special needs of use in harsh environments.
