Description
Technical Field
[0001] This utility model relates to the field of diving equipment technology, and in particular to a transport frame for diving umbilical cords. Background Technology
[0002] In diving operations, diving umbilical cord transport frames are used to store and organize diving umbilical cords. According to patent application number CN202010185983.6, entitled "A Diving Umbilical Cord and its Usage Method," and the "Safety Requirements for Air Diving" which mentions "6.7.3 When using surface-supplied air diving, there should be at least two independent main air sources, one emergency air source, two diving umbilical cords, one diving control panel, two diving telephones, two diving masks or helmets, two diving suits, two safety harnesses, two ballast belts, two pairs of fins, two diving knives, two diver emergency air cylinders, two timers, necessary tools and accessories, etc.", it is clear that diving umbilical cords are crucial in diving operations. For the safety of underwater personnel, diving umbilical cords are indispensable equipment. A single diving umbilical cord is typically up to 50 meters long and heavy; transporting multiple cords together by hand is impractical, hence the use of transport frames. Current transport frames for diving umbilical cords are equipped with spherical rollers at the bottom. The spherical rollers make it easy to transport diving umbilical cords on flat ground. However, when facing uneven terrain in the field or when it is necessary to carry the cords over stairs, ordinary spherical rollers will not be able to cross steps or pits with large height differences. Utility Model Content
[0003] The main purpose of this invention is to provide a transport frame for diving umbilical cords, which aims to improve the mobility of the transport frame.
[0004] To achieve the above objectives, the present invention provides a transport frame for diving umbilical cords, comprising:
[0005] A frame, within which a diving umbilical cord is stored;
[0006] The wheel assembly, located at the bottom of the frame, includes multiple triangular wheels. Each triangular wheel includes a roller and a triangular hub. The roller is connected to the triangular hub via a bearing, and the triangular hub is connected to the frame via a pivot.
[0007] In one embodiment, the frame has a winding and unwinding space and a receiving space arranged from top to bottom and connected to each other. The transport frame for the diving umbilical cord also includes a winch assembly. The winch assembly includes a drive motor, a rotating shaft, and a winch. The diving umbilical cord is coiled on the winch. The drive motor is located in the winding and unwinding space via the rotating shaft and can drive the diving umbilical cord to be wound and unwound on the winch. The winch is detachably mounted to the rotating shaft so that the winch can fall from the winding and unwinding space into the receiving space.
[0008] In one embodiment, the winch has a through-hole at its shaft center. The rotating shaft includes a first shaft at the output end of the drive motor and a second shaft connected to the frame. The first shaft and the second shaft are inserted from both ends of the through-hole to be detachably connected to the winch. The drive motor drives the winch to rotate via the first shaft.
[0009] In one embodiment, the winch has a locking groove at one end near the drive motor, and the first shaft has a locking protrusion at one end near the drive motor corresponding to the locking groove. After the first shaft is inserted into the insertion hole, the locking groove engages with the locking protrusion, so that the drive motor drives the winch to rotate.
[0010] In one embodiment, the first shaft and the second shaft are movable along a first axial direction to move away from or into the insertion hole, the first axial direction being the axial direction of the rotating shaft.
[0011] In one embodiment, the top of the frame is provided with two opposing translation platforms. Each translation platform includes a slide rail extending along the first axis and a support platform slidably disposed on the slide rail. The drive motor and the support frame supporting the second shaft are respectively disposed on the two support platforms.
[0012] In one embodiment, the translation platform further includes a translation drive that drives the support platform to slide on the slide rail.
[0013] In one embodiment, the translation platform further includes a locking assembly disposed on the support platform and detachably connected to the slide rail to fix the support platform to the slide rail.
[0014] In one embodiment, the winch includes a winch disc and a shaft column, the winch disc being disposed at both ends of the shaft column, the diameter of the winch disc being larger than the diameter of the loop formed when the diving umbilical cord is wound around the shaft column, and the winch disc being made of an elastic material.
[0015] In one embodiment, the frame includes a lower frame shell and an upper frame shell, with a water-filtering gap between the lower frame shell and the upper frame shell, and a water-draining hole at the bottom of the upper frame shell, the water-draining hole being connected to the water-filtering gap.
[0016] The technical solution of this utility model involves installing triangular wheels at the bottom of the frame. Each of the three vertices of the triangular wheel hub is equipped with a roller. When climbing stairs or walking on uneven surfaces, one roller always contacts the edge of a step or the top of a depression. As the triangular wheel hub rotates, it pushes the next roller to contact a higher step, creating a continuous "climbing" motion. The three rollers form a dynamic support, preventing tilting or slippage caused by single-point instability. In other words, the triangular wheels can smoothly traverse stairs, obstacles, and uneven ground, avoiding the jamming or need for additional power issues that occur with spherical rollers. Furthermore, without manual adjustment, the triangular wheels can automatically switch between rolling states on flat ground and between stairs. That is, the rollers roll normally when transporting the frame on flat ground, and the triangular wheel hub rotates to climb when encountering steps or uneven surfaces. This allows the diving umbilical transport frame to adapt to more complex terrains and quickly transport diving umbilicals, enhancing the mobility and flexibility of the diving umbilical transport frame.

[0027] This utility model proposes a transport frame for diving umbilical cords, that is, a transport frame used for storing and transferring diving umbilical cords.
[0028] Please see Figures 1 to 2 In one embodiment of this utility model, the underwater umbilical cord transport frame includes:
[0029] The frame is 100, and the submersible umbilical cord is stored inside the frame 100;
[0030] The wheel assembly 200 is located at the bottom of the frame 100 and includes multiple triangular wheels 21. Each triangular wheel 21 includes a roller 211 and a triangular hub 212. The roller 211 is connected to the triangular hub 212 through a bearing, and the triangular hub 212 is connected to the frame 100 through a pivot 216.
[0031] The technical solution of this utility model involves installing triangular wheels 21 at the bottom of the frame 100. Each of the three vertices of the triangular wheel hub 212 is equipped with a roller 211. When climbing stairs or walking on uneven surfaces, one roller 211 always contacts the edge of a step or the top of a depression. As the triangular wheel hub 212 rotates, it pushes the next roller 211 to contact a higher step, forming a continuous "climbing" motion. The three rollers 211 provide dynamic support, preventing tilting or slippage caused by single-point instability. In other words, the triangular wheels 21 can smoothly traverse stairs, obstacles, and uneven ground, avoiding the jamming or need for additional power issues that occur with spherical rollers 211. Furthermore, without manual adjustment, the triangular wheels 21 can automatically switch between rolling states on flat ground and between stairs. That is, when transporting the frame 100 on flat ground, the rollers 211 roll normally; when encountering steps or uneven surfaces, the triangular wheel hub 212 rotates to climb. This allows the diving umbilical transport frame to adapt to more complex terrains and quickly transport diving umbilicals, enhancing the mobility and flexibility of the diving umbilical transport frame.
[0032] In one embodiment, the frame 100 has a winding and unwinding space 101 and a receiving space 102 arranged from top to bottom and connected to each other. The transport frame for the diving umbilical cord also includes a winch assembly 11. The winch assembly 11 includes a drive motor 111, a rotating shaft 112 and a winch 113. The diving umbilical cord is disposed on the winch 113. The drive motor 111 is disposed in the winding and unwinding space 101 via the rotating shaft 112 and can drive the diving umbilical cord to be wound and unwound on the winch 113. The winch 113 and the rotating shaft 112 are detachably installed so that the winch 113 can fall from the winding and unwinding space 101 into the receiving space 102. The winch 113 has a insertion hole 113a at its shaft center, and the rotating shaft 112 includes a first shaft 112a located at the output end of the drive motor 111 and a second shaft 112b connected to the frame 100. The first shaft 112a and the second shaft 112b are respectively inserted from both ends of the insertion hole 113a to be detachably connected to the winch 113. The drive motor 111 drives the winch 113 to rotate through the first shaft 112a, and the second shaft 112b assists the first shaft 112a in supporting the winch 113. Furthermore, when transporting the diving umbilical cord, the diving umbilical cord is housed in the receiving space 102. When the diving umbilical cord transport frame arrives at the diving operation point... When divers need to work together, the winch 113 is removed from the storage space 102 and connected to the drive motor 111 and the rotating shaft 112 located in the unwinding / rewinding space 101. This allows for unwinding in coordination with the divers' movements. When the divers finish their work and tidy up their diving equipment, the drive motor 111 drives the winch 113 to wind up the diving umbilical cord. After winding, the diving umbilical cord is placed back into the storage space 102 for transport or temporary storage. In other embodiments, the frame 100 may not have a connected unwinding / rewinding space 101 and storage space 102, or the rotating shaft 112 may be a shaft that passes through the winch 113 along its axial direction.
[0033] In one embodiment, the winch 113 has a locking groove 113b at one end near the drive motor 111, and a locking protrusion 112c corresponding to the locking groove 113b at one end near the drive motor 111. After the first shaft 112a is inserted into the insertion hole 113a, the locking groove 113b and the locking protrusion 112c engage, so that the drive motor 111 drives the winch 113 to rotate. That is, when the output end of the drive motor 111 rotates, the first shaft 112a rotates accordingly. At this time, the locking protrusion 112c exerts a pushing force on the locking groove 113b to drive the winch 113 to rotate with the first shaft 112a. In other embodiments, the cross-sectional shape of the insertion hole 113a may be set to a non-circular shape, and the cross-sectional shape of the first shaft 112a may be adapted to the cross-sectional shape of the insertion hole 113a, so that the first shaft 112a engages with the insertion hole 113a and drives the winch 113 to rotate.
[0034] In one embodiment, the first shaft 112a and the second shaft 112b are movable along a first axial direction to move away from or into the insertion hole 113a. The first axial direction is the axial direction of the rotating shaft 112. Further, the top of the frame 100 is provided with two opposing translation platforms 12. Each translation platform 12 includes a slide rail 121 extending along the first axial direction and a support platform 122 slidably disposed on the slide rail 121. The drive motor 111 and the support frame 123 supporting the second shaft 112b are respectively disposed on the two support platforms 122. After the winch 113 is removed from the receiving space 102, the support platform 122, which is equipped with the drive motor 111 or the support frame 123, is moved closer to another support platform 122 so that a insertion hole 113a on the winch 113 can first connect with the first shaft 112a or the second shaft 112b. Then, the other support platform 122 is moved so that the second shaft 112b or the first shaft 112a is inserted into another insertion hole 113a on the winch 113, so that the winch 113 is placed in the take-up and unwinding space 101 and the assembly with the drive motor 111 is completed. When it is necessary to move the winch 113 from the take-up and unwinding space 101 into the receiving space 102, the two support platforms 122 are moved away from each other, so that the winch 113 falls into the receiving space 102 by itself. Furthermore, the translation platform 12 is provided with a translation drive to drive the movement of the support platform 122. Furthermore, the translation platform also includes a locking component, which is disposed on the support platform and detachably connected to the slide rail to fix the support platform and the slide rail. When the support platform slides to a preset position, the locking component locks the support platform and the slide rail in place, preventing accidents caused by the support platform shaking when the drive motor is working and the frame is moving. When both the locking component and the translation drive are present, the locking component reduces the possibility of the drive component being impacted by the torque between the drive motor and the winch during operation, leading to malfunction or damage. In other embodiments, the support platform 122 can also be moved manually on the slide rail 121.
[0035] In one embodiment, the winch 113 includes a winch disc 113c and a shaft post 113d. The winch disc 113c is disposed at both ends of the shaft post 113d. The diameter of the winch disc 113c is larger than the diameter of the loop formed when the diving umbilical cord is wound around the shaft post 113d. The winch disc 113c is made of an elastic material. That is, when the winch 113 falls from the winding and unwinding space 101 into the receiving space 102, the winch disc 113c first collides with the bottom wall of the frame 100. The winch disc 113c, being made of an elastic material, can buffer the impact force with the bottom wall of the frame 100 through elastic deformation, preventing damage to the diving umbilical cord. In other embodiments, the winch 113 may not have a winch disc 113c. Before the winch 113 falls into the receiving space 102, the user wraps the surface of the diving umbilical cord with shock-absorbing material.
[0036] In one embodiment, the frame 100 includes a lower frame shell 16 and an upper frame shell 17, with a water-filtering gap 172 between the lower frame shell 16 and the upper frame shell 17. A drain hole 171 is located at the bottom of the upper frame shell 17, and the drain hole 171 communicates with the water-filtering gap 172. After the diving umbilical cord completes its operation, a large amount of seawater adheres to its surface. During the winding process, seawater drips into the frame and enters the water-filtering gap 172 through the drain hole 171. When the diving umbilical cord is housed in the receiving space 102, the seawater adhering to the umbilical cord flows from the receiving space 102 into the drain hole 171, thus entering the water-filtering gap 172. In other embodiments, the drain hole 171 and the water-filtering gap 172 may not be provided.
[0037] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
