Quick release cable device

Abstract

This invention provides a rapid release device to prevent accidental detachment, relating to the technical field of release devices. It includes an anchor hook frame, with a fixed rod installed through one end of the frame. An anchor hook is movably fitted onto the outer side of the fixed rod and is movably installed inside the anchor hook frame. This invention achieves active anti-accidental detachment through a mechanical transmission structure. When the anchor hook rotates upwards around the fixed rod to reset, a third gear revolves and, through a fourth gear, pushes a second shaft downwards, causing the third gear to mesh with the second gear. This, in turn, drives the first gear to rotate, pushing the arc-shaped extension frame outwards and compressing the spring. At this time, the upper end of the arc-shaped extension frame extends outwards, forming a physical barrier against the upper end of the anchor hook. Even if the cable experiences an upward force due to swaying, the arc-shaped extension frame can prevent it from detaching from the anchor hook, avoiding accidental detachment caused by swaying and significantly improving the mooring safety of ships under harsh conditions.

[0001] This invention relates to the field of cable release device technology, and more specifically, to a rapid cable release device to prevent accidental release. Background Technology

[0002] A release hook is a core piece of equipment for mooring ships at a dock. It is used to replace traditional mooring bollards and realize the rapid winding, mooring, and emergency release of cables. For example, an electric rapid release hook proposed in application number "CN202510245581.3" includes a base. A winding assembly for winding cables is fixedly installed on one side of the base. An extension frame is fixedly installed on the other side of the base. Several connecting shafts are provided inside the extension frame. A cable hook assembly for hooking the cable is installed inside each connecting shaft. A guide assembly for guiding the position of the cable is fixedly installed at the upper end of the base. However, in the above-mentioned technical solutions, severe shaking can easily occur between the cable and the anchor hook during severe weather conditions such as thunderstorms. Existing devices lack an effective anti-detour structure, which may lead to accidental cable detachment and affect the safety of ship mooring. Therefore, we propose a rapid cable release device to solve the above problems. Summary of the Invention

Existing devices lack an effective anti-accidental detachment structure, which may lead to the cable accidentally falling off and affecting the mooring safety of the ship.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A quick-release cable device to prevent accidental detachment includes an anchor hook frame. A fixed rod is installed through one end of the anchor hook frame. An anchor hook is movably sleeved on the outer side of the fixed rod and movably installed inside the anchor hook frame. A locking block is installed inside the anchor hook frame at the end away from the fixed rod, and the locking block is engaged with the anchor hook. A fitting groove is provided on the side of the anchor hook away from the locking block. A placement box is fitted inside the fitting groove. A protective mechanism is installed between the placement box and the anchor hook. A groove is provided through the interior of the protective mechanism. An arc-shaped extension frame is movably installed through the interior of the groove at the end away from the fixed rod. Several teeth are equidistantly installed on the lower end of the arc-shaped extension frame near the fixed rod. The lower end of the groove is movably fitted with... The device is equipped with a first gear and a second gear, which are meshed together. The first gear is also meshed with the teeth of the gear. A first rotating shaft is movably installed through the interior of each of the first and second gears. The first rotating shaft is installed inside a groove. A temporary storage groove is provided at the lower end of the fitting groove. The body of a fixing rod is movably installed through the temporary storage groove. A fourth gear is installed through the outside of the fixing rod inside the temporary storage groove. A third gear is movably installed at one end of the temporary storage groove. The lower end of the third gear is movably located inside the groove and meshes with the second gear. A second rotating shaft is movably installed through the interior of the third gear and is movably installed inside the temporary storage groove.

[0005] Preferably, an arc-shaped sliding groove is provided through the front and rear sides of the groove near one end of the arc-shaped extension frame, and a slider is installed on the front and rear sides of the arc-shaped extension frame, and the slider is respectively engaged and installed inside the arc-shaped sliding groove.

[0006] Preferably, arc-shaped guide rods are installed inside the arc-shaped groove, and the slider is provided with a locking groove on the side near the arc-shaped guide rod, and the rod body of the arc-shaped guide rod is respectively locked and installed inside the locking groove.

[0007] Preferably, a blocking block is installed inside the arc-shaped groove, and springs are respectively sleeved on the outer side of the arc-shaped guide rod located between the slider and the blocking block.

[0008] Preferably, the upper and lower sides of the upper end of the arc-shaped slide are respectively provided with limiting grooves, and the side of the block away from the spring is respectively installed with limiting blocks, and the limiting blocks and the limiting grooves are connected by bolts through threads.

[0009] Preferably, the lower ends of the front and rear sides of the temporary storage tank are respectively provided with placement slots, and support blocks are installed inside the placement slots by bolts.

[0010] Preferably, the support blocks are provided with arc-shaped guide grooves on their adjacent sides, and the arc-shaped guide grooves are coaxially arranged with the fixing rods. The front and rear ends of the second rotating shaft are respectively engaged and installed inside the arc-shaped guide grooves.

[0011] Preferably, the placement box includes a first housing and a second housing, which are engaged with each other, and the groove is located between the first housing and the second housing.

[0012] Preferably, the first housing and the second housing are engaged and installed inside the fitting groove and are in contact with its inner wall.

[0013] Preferably, the placement box and the anchor hook are connected by several bolts via threads.

[0014] 1. In this invention, an active anti-disengagement function is achieved through a mechanical transmission structure. When the anchor hook rotates upward and resets around the fixed rod, the third gear revolves and pushes the second shaft downward through the fourth gear, causing the third gear to mesh with the second gear. This, in turn, drives the first gear to rotate, pushing the arc-shaped extension frame outward and compressing the spring. At this time, the upper end of the arc-shaped extension frame extends outward, forming a physical barrier to the upper end of the anchor hook. Even if the cable generates an upward force due to swaying, the arc-shaped extension frame can prevent it from detaching from the anchor hook, avoiding accidental disengagement caused by swaying, and significantly improving the mooring safety of the ship under harsh working conditions.

[0015] 2. In this invention, when rapid cable release is required, the anchor hook rotates downwards, the third gear revolves and is driven by the meshing of the fourth gear, which drives the second rotating shaft to move upwards along the arc-shaped guide groove, causing the third gear to separate from the second gear. At this time, the spring quickly pushes the slider and the arc-shaped extension frame to reset, releasing the obstruction to the anchor hook. This process does not require additional power, but only triggers mechanical linkage through the rotation of the anchor hook, ensuring that the arc-shaped extension frame does not constitute an obstacle when releasing the cable, realizing the dual functions of preventing accidental release and rapid cable release, ensuring safety without affecting the efficiency of emergency operations.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 14As shown, a quick-release cable device to prevent accidental detachment includes an anchor hook frame 1. A fixed rod 5 is installed through one end of the anchor hook frame 1. An anchor hook 2 is movably sleeved on the outer side of the fixed rod 5 and is movably installed inside the anchor hook frame 1. A locking block 6 is installed inside the anchor hook frame 1 at the end away from the fixed rod 5. The locking block 6 is engaged with the anchor hook 2. A fitting groove 3 is provided on the side of the anchor hook 2 away from the locking block 6. A placement box 4 is engaged inside the fitting groove 3. A protective mechanism 7 is installed between the placement box 4 and the anchor hook 2. A groove 701 is provided through the interior of the protective mechanism 7. An arc-shaped extension frame 702 is movably installed through the interior of the groove 701 at the end away from the fixed rod 5. Several teeth 711 are equidistantly installed on the lower end of the arc-shaped extension frame 702 near the fixed rod 5. A first gear 712 and a second gear 71 are movably installed on the lower end of the groove 701. 3. The first gear 712 and the second gear 713 are meshed together. The first gear 712 is meshed with the tooth 711. The first rotating shaft 714 is movably installed through the middle of the first gear 712 and the second gear 713 respectively. The first rotating shaft 714 is installed inside the groove 701 respectively. The lower end of the fitting groove 3 is provided with a temporary storage groove 715. The rod body of the fixing rod 5 is movably installed through the inside of the temporary storage groove 715. The fourth gear 718 is installed through the outside of the rod body of the fixing rod 5 inside the temporary storage groove 715. The third gear 716 is movably installed at one end of the inside of the temporary storage groove 715. The lower end of the third gear 716 is movably located inside the groove 701 and meshes with the second gear 713. The middle of the inside of the third gear 716 is installed through the second rotating shaft 717. The second rotating shaft 717 is movably installed inside the temporary storage groove 715.

[0020] like Figure 10 , Figure 13 and Figure 14 As shown, an arc-shaped slide groove 703 is provided through the front and rear sides of the groove 701 and near the end of the arc-shaped extension frame 702. A slider 704 is installed on the front and rear sides of the arc-shaped extension frame 702. The sliders 704 are respectively engaged inside the arc-shaped slide groove 703. An arc-shaped guide rod 705 is installed inside the arc-shaped slide groove 703. A locking groove 706 is provided on the side of the slider 704 near the arc-shaped guide rod 705. The rod body of the arc-shaped guide rod 705 is respectively engaged inside the locking groove 706. A blocking block 708 is engaged inside the arc-shaped slide groove 703. A spring 707 is sleeved on the outer side of the rod body of the arc-shaped guide rod 705 located between the slider 704 and the blocking block 708. A limiting groove 709 is provided on the upper and lower sides of the upper end of the arc-shaped slide groove 703. A limiting block 710 is installed on the side of the blocking block 708 away from the spring 707. A bolt is threaded between the limiting block 710 and the limiting groove 709.

[0021] The sliders 704 on both sides of the arc-shaped extension frame 702 slide within the arc-shaped groove 703. The arc-shaped guide rod 705 is embedded in the engaging groove 706, restricting the movement trajectory of the slider 704. The spring 707 is sleeved on the arc-shaped guide rod 705. When the arc-shaped extension frame 702 moves outward, the spring 707 is compressed. When the external force disappears, the spring 707 pushes it to reset. The block 708 is fixed in the limiting groove 709 by the limiting block 710 and bolts to prevent the slider 704 from falling out. The cooperation between the arc-shaped groove 703 and the slider 704 ensures that the arc-shaped extension frame 702 moves smoothly. The spring 707 provides the reset power, so that when the anchor hook 2 rotates downward about the fixed rod 5 as the axis, the second gear 713 and the third gear 716 separate. Then the spring 707 can push the slider 704 and the arc-shaped extension frame 702 to quickly reset, avoiding obstruction of the cable untying operation. The block 708 enhances the stability and safety of the structure.

[0022] like Figure 12 As shown, the lower ends of the front and rear sides of the temporary storage tank 715 are respectively provided with placement tanks 719. The placement tanks 719 are respectively installed with support blocks 720 by bolts. The side of the support blocks 720 that are close to each other is respectively provided with arc-shaped guide grooves 721. The arc-shaped guide grooves 721 are coaxially arranged with the fixing rod 5. The front and rear ends of the second rotating shaft 717 are respectively engaged and installed inside the arc-shaped guide grooves 721.

[0023] The support block 720 is fixed in the placement groove 719 by bolts. Its arc-shaped guide groove 721 is coaxial with the fixing rod 5. The two ends of the second rotating shaft 717 are inserted into the arc-shaped guide groove 721. When the third gear 716 is driven by the fourth gear 718, the second rotating shaft 717 moves up and down along the arc-shaped guide groove 721, controlling the meshing and disengagement of the third gear 716 and the second gear 713. This allows the arc-shaped guide groove 721 to provide a precise movement trajectory for the second rotating shaft 717, ensuring the accuracy of the meshing between the second gear 713 and the third gear 716. This achieves automatic switching between preventing accidental disconnection and rapid cable disconnection, without the need for an additional power device, saving energy and facilitating maintenance.

[0024] like Figure 3 , Figure 5 , Figure 12 and Figure 13 As shown, the placement box 4 includes a first housing 401 and a second housing 402, which are engaged and connected. A groove 701 is provided between the first housing 401 and the second housing 402. The first housing 401 and the second housing 402 are engaged and installed inside the fitting groove 3 and are attached to its inner wall. Several bolts are threadedly installed between the placement box 4 and the anchor hook 2.

[0025] The placement box 4 is formed by the engagement of the first housing 401 and the second housing 402. The groove 701 is located between the two and accommodates the protective mechanism 7 inside. The placement box 4 is fixed in the fitting groove 3 by bolts and is tightly connected to the anchor hook 2. The engagement structure facilitates installation and disassembly, and makes it convenient to inspect and maintain the protective mechanism 7. The bolt fixing ensures that the connection between the placement box 4 and the anchor hook 2 is firm and ensures the normal operation of the protective mechanism 7.

[0026] The working principle of this anti-accidental disconnection and rapid cable release device: In use, when the anchor hook rotates upward and resets around the fixed rod 5, it drives the third gear 716 to revolve around the fixed rod 5. Simultaneously, it meshes with the fourth gear 718, causing the fourth gear 718 to first drive the third gear 716 to move the second rotating shaft 717 downward along the arc-shaped guide groove 721. At the same time, the third gear 716 rotates on its own axis. Then, when the third gear 716 moves downward, it meshes with the second gear 713, so that when the third gear 716 rotates on its own axis, it can drive the second gear 713. Then, the second gear 713 can drive the first gear 712, so that the first gear 712, in conjunction with the teeth 711, pushes the arc-shaped extension frame 702 outward, allowing the upper end of the arc-shaped extension frame 702 to move to the outside, forming a physical barrier on the upper end of the anchor hook 2, preventing the cable from accidentally coming off. At the same time, the arc-shaped extension frame 702 also drives the slider 704 to slide along the arc-shaped guide rod 705 to compress the spring 707. Then, when the anchor hook 2 rotates downward around the fixed rod 5, the anchor rod 2 can drive the third gear 716 to rotate in the opposite direction around the fixed rod 5. Then, the fourth gear 718 can push the third gear 716 and the second rotating shaft 717 to move upward through meshing, thereby separating the third gear 716 from the second gear 713, breaking the transmission chain. Then, the compressed spring 707 can release its elastic potential energy to push the slider 704 and the arc-shaped extension frame 702 to quickly reset along the arc-shaped groove 703, allowing the arc-shaped extension frame 702 to quickly return to the inside of the groove 701, releasing the obstruction to the cable.

[0027] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
