[0025] 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.

Furthermore, unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] See Figure 1 and Figure 4 This utility model provides an LNG refueling pipe bracket, including a base frame 1, a saddle 2, a support rod 3, and a foot pedal 4. The bottom end of the base frame 1 is fixed to the ship's deck. The saddle 2 supports the LNG refueling pipe 7. One end of the saddle 2 is hinged to the top of the base frame 1, allowing the saddle 2 to rotate relative to the base frame 1. The other end of the saddle 2 is hinged to one end of the support rod 3 and one end of the foot pedal 4, respectively. The free end of the foot pedal 4 has a foot pedal 41. A crossbar 11 is provided in the middle of the base frame 1. The free ends of the support rod 3 and the foot pedal 4 are detachably connected to the crossbar 11. The crossbar 11 improves the stability of the base frame 1, ensuring the bracket remains securely fixed even when the ship rolls due to wind and waves.

[0028] In use, the operator places their foot on the foot pedal 41 and pushes upwards to rotate the saddle 2 to the support position of the LNG refueling pipe 7. Then, the free end of the foot pedal 4 is connected to the crossbar 11 to further lift the saddle 2. Finally, the free end of the support rod 3 is connected to the crossbar 11. The support rod 3 and foot pedal 4 simultaneously support the saddle 2, increasing its support force. When refueling is not required, the operator first removes the free end of the support rod 3 from the crossbar 11. Then, the operator places their foot on the foot pedal 41 and removes the free end of the foot pedal 4 from the crossbar 11. The operator then slowly lowers the saddle 2 using the foot pedal 4, folding it away from the base frame 1. As can be seen, this bracket is equipped with a retractable foot pedal 4, allowing the saddle 2 to be opened and closed in just a few minutes, simplifying the process, reducing operator workload, and improving refueling efficiency.

[0029] This support bracket can be used for various LNG bunkering modes, including ship-to-ship (STS) and port-to-ship (PTS). The bracket helps to securely connect the LNG refueling pipe 7 between two ships, supporting the weight of the LNG refueling pipe 7 and the LNG within it. Whether it's a large container ship, tanker, bulk carrier, or roll-on / roll-off ship, as long as LNG is used as fuel, this bracket can be used to ensure the safe and smooth progress of bunkering operations.

[0030] The fixed position of the base frame 1 is selected according to the requirements. Preferably, when the saddle 2 is folded, the saddle 2 does not protrude from the hull.

[0031] The LNG refueling pipe 7 is a flexible hose. In this embodiment, the saddle 2 is arc-shaped to prevent the LNG refueling pipe 7 from breaking due to excessively small bend diameter, which would also affect the refueling effect. The base frame 1, support rod 3, and foot pedal 4 are made of stainless steel, ensuring a stable structure capable of withstanding the weight of the refueling hose and various dynamic loads generated during refueling, ensuring the hose will not be damaged or leak due to swaying or twisting. The saddle 2 is made of duplex stainless steel to provide excellent corrosion resistance and low-temperature resistance. Furthermore, the contact surface between the saddle 2 and the LNG refueling pipe 7 is provided with a Teflon pad to prevent material embrittlement and failure of the saddle 2 under the low-temperature environment of LNG refueling.

[0032] Among them, see Figures 1 to 4 The detachable connection structure between the free end of the support rod 3 and the crossbar 11 is as follows: the free end of the support rod 3 is provided with a first insertion hole 31, and the bottom of the crossbar 11 is provided with two first ear plates 12, each ear plate 12 having a first through hole. Figure 2The support rod 3 is horizontally through-type, with its free end extending between two first ear plates 12. A first pin 32 passes sequentially through the first through hole, first insertion hole 31 of one first ear plate 12, and the first through hole of the other first ear plate 12 to connect the free end of the support rod 3 to the crossbar 11. The first pin 32 passes through the two first ear plates 12 and the first insertion hole 31 of the support rod 3, with the first ear plates 12 located at the bottom of the crossbar 11, enabling a detachable connection between the free end of the support rod 3 and the crossbar 11. When air is needed, the first pin 32 is passed through the two first ear plates 12 and the first insertion hole 31 of the support rod 3 to connect the free end of the support rod 3 to the crossbar 11; when air is not needed, the first pin 32 is pulled out to separate the free end of the support rod 3 from the crossbar 11. In this embodiment, two support rods 3 are provided, respectively located on both sides of the foot pedal 4, which helps to improve the support force on the saddle 2. In practice, the number of support rods 3 is not limited and can be increased or even increased as needed.

[0033] The detachable connection structure between the free end of the foot pedal 4 and the crossbar 11 is as follows: the free end of the foot pedal 4 is provided with a second insertion hole 42, and the bottom of the crossbar 11 is provided with two second ear plates 13, each ear plate 13 having a second through hole. Figure 2 The pedal lever 4 is horizontally through-type, with its free end extending between two second ear plates 13. A second pin 43 passes sequentially through the second through hole, second insertion hole 42 of one second ear plate 13, and the second through hole of the other second ear plate 13 to connect the free end of the pedal lever 4 to the crossbar 11. The second pin 43 passes through the two second ear plates 13 and the first insertion hole 31 of the pedal lever 4. The second ear plates 13 are located at the bottom of the crossbar 11, enabling a detachable connection between the free end of the pedal lever 4 and the crossbar 11. When gas is needed, the second pin 43 is passed through the two second ear plates 13 and the second insertion hole 42 of the pedal lever 4 to connect the free end of the pedal lever 4 to the crossbar 11; when gas is not needed, the second pin 43 is pulled out to detach the free end of the pedal lever 4 from the crossbar 11.

[0034] Preferred, see Figure 1 Multiple first insertion holes 31 are provided along the length of the support rod 3. A first pin 32 passes sequentially through the first through hole of one of the first ear plates 12, one of the first insertion holes 31, and the first through hole of another first ear plate 12 to connect the free end of the support rod 3 to the crossbar 11. When the free end of the support rod 3 is connected to the crossbar 11, by inserting the first pin 32 into different first insertion holes 31, the angle between the saddle 2 and the base frame 1 can be adjusted, thereby flexibly adjusting the support angle of the saddle 2 and improving its versatility in various situations.

[0035] Preferred, see Figure 2The first pin 32 is connected to the support rod 3 via the first chain 33 to prevent the first pin 32 from being lost; similarly, the second pin 43 is connected to the foot pedal 4 via the second chain 44 to prevent the second pin 43 from being lost.

[0036] Preferred, Participate Figures 2 to 4 A rotating block 5 is hinged to the free end of the first pin 32. After the first pin 32 passes through the first ear plates 12 and the first insertion hole 31 of the support rod 3, rotating the rotating block 5 prevents the first pin 32 from dislodging from the first through hole of the first ear plate 12 and the first insertion hole 31 of the support rod 3, thereby improving the stability of the bracket. Similarly, a rotating block 5 can be hinged to the free end of the second pin 43. After the second pin 43 passes through the second ear plates 13 and the second insertion hole 42 of the foot pedal 4, rotating the rotating block 5 prevents the second pin 43 from dislodging from the second through hole of the second ear plate 13 and the second insertion hole 42 of the foot pedal 4.

[0037] Preferably, the saddle 2 is provided with a first storage component and a second storage component near its hinge end. The first storage component can be detachably connected to the support rod 3, and the second storage component can be detachably connected to the pedal rod 4. When inflatable tires are not required, the support rod 3 can be folded towards the saddle 2 by connecting to the first storage component, and the pedal rod 4 can be folded towards the saddle 2 by connecting to the second storage component.

[0038] For details, see Figures 2 to 4 The first storage component includes two third ear plates 21. The third ear plates 21 are provided with third through holes 211. The free end of the support rod 3 extends between the two third ear plates 21. The first pin 32 passes through the third through hole 211, the first insertion hole 31 of one third ear plate 21 and the third through hole 211 of the other third ear plate 21 in sequence so that the free end of the support rod 3 is connected to the first storage component, thereby enabling the support rod 3 to fold towards the saddle 2.

[0039] Similarly, the second storage component includes two fourth ear plates 22. The fourth ear plates 22 are provided with fourth through holes. The free end of the foot pedal 4 extends between the two fourth ear plates 22. The second pin 43 passes through the fourth through hole of one of the fourth ear plates 22, the second insertion hole 42 and the fourth through hole of the other fourth ear plate 22 in sequence to connect the free end of the foot pedal 4 with the second storage component, so that the support rod 3 can be folded towards the saddle 2.

[0040] When refueling is not required, the operator first removes the free end of the support rod 3 from the crossbar 11. Then, the operator places their foot on the foot pedal 41 and removes the free end of the foot pedal 4 from the crossbar 11. The operator then slowly lowers the saddle 2 through the foot pedal 4 so that the saddle 2 is folded and stored on one side of the base frame 1. Finally, the free end of the support rod 3 is inserted between the two third ear plates 21. The first pin 32 passes through the third through hole 211, the first insertion hole 31 of one third ear plate 21, and the third through hole 211 of the other third ear plate 21 in sequence. The free end of the foot pedal 4 is then inserted between the two fourth ear plates 22. The second pin 43 passes through the fourth through hole, the second insertion hole 42 of one fourth ear plate 22, and the fourth through hole of the other fourth ear plate 22 in sequence. This allows the saddle 2, support rod 3, and foot pedal 4 to be folded, reducing the space occupied by the bracket.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
