Description

Technical Field

[0001] This utility model relates to the field of shore power winch technology, and more specifically, to a manual emergency release device for a shore power winch. Background Technology

[0002] Shore power winches are key equipment in ship shore power systems. They are used to safely and efficiently retrieve, deploy, and manage shore power cables, ensuring a stable connection to shore power when the ship is in port. This replaces the ship's auxiliary engines for power generation, reducing emissions and noise. However, in the event of an emergency power outage that causes the ship to drift a certain distance from the shore, the winch cannot be started and will pull on the cable, potentially damaging the equipment. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a manual emergency release device for shore power winches, which has the advantage of manual emergency response.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a manual emergency release device for a shore power winch, comprising a fixed base, a support block fixedly installed above the fixed base, a connecting shaft rotatably connected inside the support block, a fixed disk and a limiting plate fixedly installed outside the connecting shaft, a gear ring fixedly installed in front of the fixed disk, a driven gear fixedly installed in front of the connecting shaft, a positioning plate fixedly installed in front of the support block, a fixed shaft rotatably connected inside the positioning plate, a turntable fixedly installed in front of the fixed shaft, and a driving gear fixedly installed at the end of the fixed shaft away from the turntable, the driving gear meshing with the gear ring.

[0005] As a preferred embodiment of this utility model, a bracket is fixedly installed in front of the support block, a connecting rod is slidably connected inside the bracket, a spring is sleeved on the outside of the connecting rod, a limiting plate is fixedly installed on the side of the spring near the positioning plate, and a brake block is fixedly installed on the side of the limiting plate away from the spring, and the brake block contacts the fixed disc.

[0006] As a preferred embodiment of this utility model, a connecting block is fixedly installed in front of the connecting rod, a rotating shaft is rotatably connected inside the connecting block, a rotating ring is sleeved on the outside of the rotating shaft, a tension is fixedly installed on the outside of the rotating ring, and a pull ring is fixedly installed on the side of the tension away from the rotating ring.

[0007] As a preferred embodiment of this utility model, there are two fixed disks, both of which are disc-shaped, and the toothed ring is located in front of the front fixed disk among the two fixed disks.

[0008] As a preferred embodiment of this utility model, there are two support blocks, which are respectively located on the front sides of the two fixed disks, and the driven gear is located in front of the two support blocks.

[0009] As a preferred embodiment of this utility model, the connecting block is a cuboid, the brake block is located behind the connecting block, and the surface of the brake block has a certain curvature.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model features a gear ring fixedly installed in front of a fixed disc, a driven gear fixedly installed in front of a connecting shaft, a positioning plate fixedly installed in front of a support block, a fixed shaft rotatably connected inside the positioning plate, a turntable fixedly installed in front of the fixed shaft, and a drive gear fixedly installed at the end of the fixed shaft away from the turntable. The drive gear meshes with the gear ring. In case of a power outage in an emergency, the external drive assembly cannot mesh with the drive component and the driven gear, thus fixing the connecting shaft. When the hull moves, the fixed connecting shaft causes the cable to be pulled. At this time, the turntable is rocked by a rocker arm, causing the turntable to drive the fixed shaft and rotate the drive gear. The drive gear then meshes with the gear ring, driving the fixed disc. The rotational connection between the connecting shaft and the support block allows for emergency cable release, increasing emergency manual measures and preventing damage from cable breakage.

[0012] 2. This utility model features a spring sleeved on the outside of the connecting rod. A limiting plate is fixedly installed on the side of the spring near the positioning plate, and a brake block is fixedly installed on the side of the limiting plate away from the spring. The brake block is in contact with the fixed disc, and the spring continuously provides elastic force to press the limiting plate, causing the limiting plate to fit against the positioning plate. At this time, the brake block is pushed by the elastic force of the spring to continuously press the fixed disc. This increases the friction between the brake block and the fixed disc, reducing the rotation speed of the fixed disc through the connecting shaft and the support block, thus achieving a slow rotation effect. This prevents the fixed disc from quickly falling off under the influence of gravity along with the cable during normal power connection. Attached Figure Description

[0019] 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.

[0020] like Figures 1 to 5 As shown, this utility model provides a manual emergency release device for a shore power winch, including a fixed base 1, a support block 2 fixedly installed on the top of the fixed base 1, a connecting shaft 3 rotatably connected inside the support block 2, a fixed plate 4 and a limiting plate 5 fixedly installed on the outside of the connecting shaft 3, a gear ring 6 fixedly installed in front of the fixed plate 4, a driven gear 7 fixedly installed in front of the connecting shaft 3, a positioning plate 8 fixedly installed in front of the support block 2, a fixed shaft 10 rotatably connected inside the positioning plate 8, a turntable 9 fixedly installed in front of the fixed shaft 10, and a driving gear 11 fixedly installed at the end of the fixed shaft 10 away from the turntable 9, the driving gear 11 meshing with the gear ring 6.

[0021] In the event of a power outage during an emergency, the external drive components cannot engage with the drive components and driven gear 7, thus fixing the connecting shaft 3. When the hull moves, the cable will be pulled due to the fixed connecting shaft 3. At this time, the turntable 9 is turned by rocker arm 12, causing the turntable 9 to drive the fixed shaft 10 to rotate the drive gear 11. The drive gear 11 will then engage with the gear ring 6, thereby driving the fixed plate 4. The cable is released in an emergency through the rotational connection between the connecting shaft 3 and the support block 2, thereby increasing emergency manual measures and preventing the cable from being pulled off and damaged.

[0022] Among them, a bracket 13 is fixedly installed in front of the support block 2, a connecting rod 14 is slidably connected inside the bracket 13, a spring 15 is sleeved on the outside of the connecting rod 14, a limit plate 16 is fixedly installed on the side of the spring 15 near the positioning plate 8, and a brake block 17 is fixedly installed on the side of the limit plate 16 away from the spring 15, and the brake block 17 contacts the fixed plate 4.

[0023] Spring 15 will always provide elastic force to press the second limiting plate 16, so that the second limiting plate 16 and the positioning plate 8 are in contact. At this time, the brake block 17 will be pushed by the elastic force of spring 15 to press the fixed plate 4. At this time, the friction between the brake block 17 and the fixed plate 4 will increase, so that the rotation speed of the fixed plate 4 through the connecting shaft 3 and the support block 2 will be reduced, so that it has a slow rotation effect, thereby preventing the fixed plate 4 from falling off quickly under the influence of gravity along with the cable when the power is connected normally.

[0024] A connecting block 18 is fixedly installed in front of the connecting rod 14. A rotating shaft 19 is rotatably connected inside the connecting block 18. A rotating ring 20 is sleeved on the outside of the rotating shaft 19. A tension 21 is fixedly installed on the outside of the rotating ring 20. A pull ring 22 is fixedly installed on the side of the tension 21 away from the rotating ring 20.

[0025] When manually releasing the cable in an emergency, the friction between the brake block 17 and the fixed disc 4 makes it more difficult to rotate the device. At this time, pulling the pull ring 22 causes the tension 21 to pull the rotating shaft 19 through the rotating ring 20, which in turn causes the brake block 17 to move forward through the connecting block 18 and the connecting rod 14. This causes the spring 15 to contract slightly, thereby reducing the friction between the brake block 17 and the fixed disc 4, thus facilitating manual release.

[0026] There are two fixed disks 4, both of which are disc-shaped. The toothed ring 6 is located in front of the front fixed disk 4.

[0027] The main function of the two fixed discs 4 is to limit the cable wound on the surface of the connecting shaft 3, so as to facilitate the winding and unwinding of the cable.

[0028] There are two support blocks 2, which are located on the front sides of the two fixed disks 4 respectively, and the driven gear 7 is located in front of the two support blocks 2.

[0029] Driven gear 7 meshes with an external drive assembly, so that it is driven at a certain point, causing the fixed disk 4 to rotate, thereby achieving the effect of stably releasing the cable.

[0030] The connecting block 18 is a cuboid, the brake block 17 is located behind the connecting block 18, and the surface of the brake block 17 has a certain curvature.

[0031] The main function of the brake block 17 is to maintain the friction generated by the compression of the fixed disc 4, and the curvature of its surface can ensure that the fixed disc 4 can rotate at a certain speed so that it will not be locked.

[0032] Working principle and usage process of this utility model:

[0033] First, a gear ring 6 is fixedly installed in front of the fixed plate 4, a driven gear 7 is fixedly installed in front of the connecting shaft 3, and a positioning plate 8 is fixedly installed in front of the support block 2. A fixed shaft 10 is rotatably connected inside the positioning plate 8, and a turntable 9 is fixedly installed in front of the fixed shaft 10. A drive gear 11 is fixedly installed at the end of the fixed shaft 10 away from the turntable 9. The drive gear 11 meshes with the gear ring 6. In case of an emergency power failure, the external drive component cannot mesh with the drive component and the driven gear 7, so the connecting shaft 3 is fixed. When the hull moves, the cable will be pulled because the connecting shaft 3 is fixed. At this time, the turntable 9 is rocked by the rocker arm 12, so that the turntable 9 drives the fixed shaft 10 to rotate the drive gear 11. The drive gear 11 will mesh with the gear ring 6, so that the fixed plate 4 is driven. The cable is released in an emergency through the rotational connection between the connecting shaft 3 and the support block 2, thereby increasing emergency manual measures and preventing the cable from being pulled off and damaged.

[0034] Secondly, a spring 15 is sleeved on the outside of the connecting rod 14. A limiting plate 16 is fixedly installed on the side of the spring 15 near the positioning plate 8, and a brake block 17 is fixedly installed on the side of the limiting plate 16 away from the spring 15. The brake block 17 is in contact with the fixed plate 4. The spring 15 will always provide elastic force to squeeze the limiting plate 16, so that the limiting plate 16 and the positioning plate 8 are in contact. At this time, the brake block 17 will be pushed by the elastic force of the spring 15 to squeeze the fixed plate 4. At this time, the friction between the brake block 17 and the fixed plate 4 will increase, so that the rotation speed of the fixed plate 4 through the connecting shaft 3 and the support block 2 will be reduced, so that it has a slow rotation effect, thereby preventing the fixed plate 4 from falling off quickly under the influence of gravity along with the cable when it is normally connected to the power.

[0035] Finally, when manually releasing the cable in an emergency, the friction between the brake block 17 and the fixed disc 4 makes it more difficult to rotate the device. At this time, pulling the pull ring 22 causes the tension 21 to pull the rotating shaft 19 through the rotating ring 20, which in turn causes the brake block 17 to move forward through the connecting block 18 and the connecting rod 14. This causes the spring 15 to contract slightly, thereby reducing the friction between the brake block 17 and the fixed disc 4, thus facilitating manual release.
