Description

Technical Field

[0001] This utility model relates to the technical field of ship fuel replenishment equipment, and in particular to a hose discharge device. Background Technology

[0002] Current ship fuel replenishment systems consist of a hose friction reduction device, a hose winch, and a hose. The hose friction reduction device guides the hose, the hose winch extends and retracts the hose, and the hose delivers fuel. However, in current ships, the hose friction reduction device and the hose winch are far apart, preventing the hose from being discharged by gravity. This causes the hose to accumulate between the hose friction reduction device and the hose winch, hindering the smooth operation of fuel delivery.

[0003] The utility model patent with application publication number CN 119373941 A discloses a refueling hose bracket for methanol-powered ships, including a storage box and extension components set on both sides of the storage box. The extension components are first unfolded, and then the hose is placed on the trough. When oil is being transported, the support mechanism supports the oil pipe. However, the hose bracket can only provide support and cannot help the hose to be discharged and retrieved, nor can it remove the air inside the hose during the retrieval process.

[0004] The utility model relates to a support hose used in waterborne oil refueling processes, which assists in the discharge and retrieval of the hose during its extension and retraction.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A hose discharge device includes a support mechanism, a retraction and discharge mechanism for retrieving and discharging the hose, a pushing mechanism for controlling the compression of the hose, and a limiting mechanism for restricting the direction of hose movement. The retraction and discharge mechanism includes a drive wheel and a driven wheel rotatably connected to the support mechanism on both sides. The retraction and discharge mechanism also includes a motor and a reducer for providing rotational power. The motor is located on one axial side of the drive wheel and is fixedly connected to the support mechanism. The reducer is located below the motor and is connected to the drive wheel. The pushing mechanism is arranged on both axial sides of the drive wheel, and the distance between the pushing mechanism and the drive wheel is greater than the distance between the reducer and the drive wheel. The pushing mechanism on the same side as the reducer is fixedly connected to the reducer, and the pushing mechanism on the other side is rotatably connected to the drive wheel.

[0007] By adopting the above technical solution, this utility model is located between the hose winch and the friction reduction device. After the hose is discharged by the hose winch, the hose is placed between the driving wheel and the driven wheel of this utility model. After being discharged by this utility model, the hose enters the friction reduction device. During the process of discharging or retrieving the hose, the pushing mechanism drives the driving wheel to move downward, squeezing the hose and expelling the air inside the hose. The motor drives the reducer to rotate. The reducer is fixedly connected to the driving wheel, driving the driving wheel to rotate, thereby pushing the hose to move and promoting the discharge and retrieval of the hose. During the oil transportation process, the pushing mechanism drives the driving wheel to move upward until the distance between the driving wheel and the driven wheel is not less than the outer diameter of the hose. At this time, the driven wheel provides support for the hose.

[0008] The driven wheel supports the hose. Moreover, during the hose's opening and closing process, the driving wheel and the driven wheel squeeze the hose together. The two work together, and the motor drives the reducer and the driving wheel to rotate. The sliding friction between the driving wheel and the hose propels the hose to move, thereby achieving the effect of discharging and retrieving the hose.

[0009] The present invention is further configured as follows: the support mechanism includes a base and a support column located above the base and fixedly connected to the base. A rectangular frame is fixedly connected above the support column. The rectangular frame has an opening in the middle. The number of support columns is [number], which are respectively located at the lower ends of the four corners of the rectangular frame. The driving wheel and the driven wheel are both located inside the support mechanism. The pushing mechanism is located above the base and fixedly connected to the base.

[0010] By adopting the above technical solution, the support mechanism plays a supporting role for the entire device's pushing and retracting mechanisms, while the rectangular frame is set around the driving and driven wheels to protect them.

[0011] The present invention is further configured such that: the pushing mechanism includes a push rod and a push rod bracket, the lower end of the push rod is fixedly connected to the base, the push rod bracket is located at the upper end of the push rod and is fixedly connected to the push rod, the push rod bracket near the reducer is fixedly connected to the reducer, and the push rod bracket located on the opposite side of the reducer is rotatably connected to the drive wheel.

[0012] By adopting the above technical solution, the push rod pushes the push rod bracket to move up and down. The push rod bracket near the reducer drives the reducer to move up and down, which in turn drives the drive wheel fixedly connected to the reducer to move up and down. The push rod bracket on the other side is rotatably connected to the drive wheel, directly driving the drive wheel to move up and down. The pushing mechanism is set on both sides of the drive wheel axis, and the drive wheel is driven to move up or down synchronously from both sides, making the pushing process more stable and reliable.

[0013] The present invention is further configured such that: the limiting mechanism is a limiting wheel, the number of limiting wheels is , each limiting wheel is respectively arranged inside the support column, and the upper and lower ends of the limiting wheel are respectively connected to the rectangular frame and the base.

[0014] By adopting the above technical solution, the limiting mechanism plays a limiting role in the hose, restricting the left and right movement range of the hose and preventing the hose from deviating from the transport track. At the same time, the limiting wheels are located on both sides of the driving wheel and the driven wheel, which protect the driving wheel and the driven wheel.

[0015] A further feature of this invention is that the limiting wheel is rotatably connected to the rectangular frame and the base.

[0016] By adopting the above technical solution, the limiting wheel is of the free-rolling type, which changes the direct planar friction between the hose and the limiting wheel into rolling friction with low friction, thus protecting the hose, reducing the wear of the hose, and extending the service life of the hose.

[0017] A further feature of this invention is that the outer surfaces of both the driving wheel and the driven wheel are lined with nitrile rubber.

[0018] By adopting the above technical solution, the friction between the driving wheel, the driven wheel and the hose is increased, making the hose retraction and extension smoother.

[0019] A further feature of this invention is that the driving wheel and the driven wheel are hollow cylindrical structures.

[0020] By adopting the above technical solution, the cylindrical structure of the driving wheel and driven wheel reduces their own weight. On the one hand, it saves materials, reduces the weight of the equipment, and makes it easier to move. On the other hand, the driving wheel is driven by a reducer (the rotation of the reducer is driven by a motor), and the up-and-down movement is driven by a push rod. The weight of the driving wheel is reduced, and the power of the driving wheel's rotation and up-and-down movement is also reduced accordingly, thus reducing energy consumption.

[0021] A further feature of this invention is that the limiting wheel is a hollow cylindrical structure.

[0022] By adopting the above technical solution, the hollow structure of the limiting wheel reduces its own weight. On the one hand, it saves materials and reduces the weight of the equipment, making it easier to move. On the other hand, the reduced weight of the limiting wheel makes it easier for it to rotate driven by the movement of the hose, further reducing the friction between the hose and the limiting wheel, reducing the wear of the hose, and extending the service life of the hose.

[0023] The beneficial effects of this utility model are:

[0024] 1. After the hose is discharged by the hose winch, the hose is placed between the driving wheel and the driven wheel of this utility model. The driven wheel supports the hose. Moreover, during the opening and closing of the hose, the driving wheel and the driven wheel squeeze the hose. The two cooperate with each other, and the motor drives the reducer and the driving wheel to rotate. The sliding friction between the driving wheel and the hose pushes the hose to move, thereby achieving the effect of discharging and recovering the hose.

[0025] 2. The limiting mechanism limits the hose, restricting its left and right movement and preventing it from deviating from the transport track. At the same time, the limiting wheels are located on both sides of the driving wheel and the driven wheel, protecting them.

[0026] 3. The limit wheel is a freely rolling type, which changes the direct planar friction between the hose and the limit wheel into rolling friction with low friction. This protects the hose, reduces wear, and extends its service life. Furthermore, the hollow structure of the limit wheel reduces its weight, saving materials and making the equipment easier to move. The reduced weight also makes it easier for the limit wheel to rotate due to the hose's movement, further reducing friction between the hose and the limit wheel, minimizing wear, and extending the hose's lifespan.

[0027] 4. The cylindrical structure of the driving and driven wheels reduces their own weight, which saves materials, reduces the weight of the equipment, and makes it easier to move. On the other hand, the driving wheel is driven by a reducer (the rotation of the reducer is driven by a motor), and the up and down movement is driven by a push rod. The weight of the driving wheel is reduced, and the power required for the rotation and up and down movement of the driving wheel is also reduced accordingly, thus reducing energy consumption.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The specific structure of this utility model:

[0033] A hose discharge device includes a support mechanism 3, a hose retraction and discharge mechanism 1, a push mechanism 2 for controlling hose compression, and a limiting mechanism for restricting hose movement direction. The support mechanism 3 includes a base 31 and support columns 33 located above and fixedly connected to the base 31. A rectangular frame 32 is fixedly connected above the support columns 33, with an opening in the middle of the rectangular frame 32. Four support columns 33 are respectively located at the lower ends of the four corners of the rectangular frame 32. The retraction and discharge mechanism 1 includes a drive wheel 11 and a driven wheel 14 rotatably connected to the support mechanism 3 on both sides. The drive wheel 11 and driven wheel 14 are hollow cylindrical structures to reduce the weight of the device. Their outer surfaces are lined with nitrile rubber to increase friction, facilitating hose discharge. They are located inside the support mechanism 3, and the cross-sections of the drive wheel 11 and driven wheel 14 fall within the rectangular structure of the rectangular frame 32. The retraction and discharge mechanism 1 also includes a motor 12 for providing rotational power. The reducer 13 and the motor 12 are servo motors. The motor 12 is located on one side of the drive wheel 11 and is fixedly connected to the support mechanism 3. The reducer 13 is located below the motor 12 and is connected to the drive wheel 11 via a shaft key. The push mechanism 2 is located on both sides of the drive wheel 11, above the base 31 and fixedly connected to the base 31. The push mechanism 2 includes a push rod 21 and a push rod bracket 22. The push rod 21 is a servo push rod. The lower end of the push rod 21 is fixedly connected to the base 31. The push rod bracket 22 is located on the upper end of the push rod 21 and is fixedly connected to the push rod 21. The push rod bracket 22 near the reducer 13 is fixedly connected to the reducer 13. The push rod bracket 22 on the opposite side of the reducer 13 is connected to the drive wheel 11 via a bearing. The limiting mechanism is a limiting wheel 4. The limiting wheel 4 is a hollow cylindrical structure. There are 4 of them. The 4 limiting wheels 4 are respectively located inside the 4 support columns 33. The upper and lower ends of the limiting wheel 4 are respectively connected to the rectangular frame 32 and the base 31 via bearings.

[0034] The working principle of this utility model:

[0035] The process of discharging or recovering the hose: This utility model is located between the hose winch and the friction reduction device. After the hose winch discharges the hose, the hose is placed between the driving wheel and the driven wheel of this utility model. After being discharged by this utility model, the hose enters the friction reduction device. The push rod 21 is activated, which drives the push rod bracket 22 to move downwards. The push rod bracket 22 on the side closer to the reducer 13 sequentially drives the reducer 13 and the driving wheel 11 connected to the reducer 13 shaft key downwards. The push rod bracket 22 on the other side directly drives the driving wheel 11 connected to its bearing downwards. The push rod mechanisms 2 on both sides work synchronously, driving the driving wheel 11 downwards. As the hose moves downwards, the distance between the driving wheel 11 and the driven wheel 14 decreases. The driving wheel 11 stops when the distance between itself and the driven wheel 14 is no greater than the difference between the outer and inner diameters of the hose. The driving wheel 11 and the driven wheel 14 work together to squeeze the hose, flattening it and expelling all the air from the hose. The motor 12 is then started, which sequentially drives the reducer 13 and the driving wheel 11 to rotate. The friction between the driving wheel 11 and the hose during rotation causes the flattened hose to move, achieving the effect of releasing or retrieving the hose. At the same time, the limiting wheel 4 limits the hose, restricting its left and right movement.

[0036] Fuel transportation process: After the hose is laid, ensure that both ends of the hose are properly connected to the fuel delivery equipment and the receiving equipment, respectively. Then, start push rod 21. Push rod 21 drives push rod bracket 22 to move upward. The push rod bracket 22 on the side closer to the reducer 13 drives the reducer 13 and the drive wheel 11 connected to the reducer 13 shaft key to move upward in sequence. The push rod bracket 22 on the other side directly drives the drive wheel 11 connected to its bearing to move upward. The push rod mechanisms 2 on both sides work synchronously to drive the drive wheel 11 to move upward. The distance between the drive wheel 11 and the driven wheel 14 increases. The drive wheel 11 stops when the distance between it and the driven wheel 14 is not less than the outer diameter of the hose. At this time, turn on the fuel delivery equipment switch. Fuel flows in the hose and supports the flattened hose. At this time, the distance between the drive wheel 11 and the driven wheel 14 is not less than the outer diameter of the hose during fuel transportation, so the hose will not be squeezed. The driven wheel 14 supports the hose. At the same time, the limit wheel 4 limits the hose and restricts the range of left and right movement of the hose.

[0037] This utility model has been described through several embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are protected by this utility model.
