Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of marine winch arms, in particular to a wind power marine winch arm limiting device. Background Art
[0002] A marine winch boom is a crucial component of a vessel's anchoring system, specifically designed to operate and control the anchor. Typically mounted at the bow or stern of a vessel, it uses its powerful mechanical force and precise control to lower and retrieve heavy anchors from the seabed while the vessel is docked or at anchor.
[0003] The existing Chinese patent with publication number CN220723422U is named as a wind power ship winch arm limiting device, which includes a ship winch arm body; one side of the ship winch arm body is rotatably connected to an extension shaft, and a limiting mechanism is provided on the surface of the extension shaft; the limiting mechanism includes a brake disc; through the structural design of the limiting mechanism, the function of quickly stopping the motor of the ship winch arm body is realized, which solves the problem that the motor of the ship winch arm body is driven to rotate due to inertia of the anchor. The user starts the motor through an external switch, and the motor is powered by an external power supply. Then the motor drives the output end to rotate counterclockwise, and then the output end of the motor drives the gear to rotate. At the same time, the gear drives the gear plate to move toward the baffle direction, and then the gear plate moves in the inner cavity of the limit block. When the gear plate moves to the specified position, the gear plate contacts the brake pad, and then the gear plate drives the brake pad to move toward the brake disc. This patent uses the contact between the brake pad and the brake disc to limit the movement, but does not lock the brake disc to completely limit its movement. The contact between the brake pad and the brake disc may be unstable and prone to sliding or shifting, resulting in poor limiting effect. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a wind turbine ship winch arm limiting device.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0014] By setting up a fixing component and a brake disc, the plug post can be pulled out from the through slot on the fixing frame by pulling the handle. At this time, the plug post can be rotated. When the plug post is rotated to a certain angle, under the action of the spring, the plug end of the plug post will be inserted into a hole slot, thereby completely fixing the brake disc and avoiding the instability factors caused by friction braking.
[0015] The utility model realizes stable braking effect and protective operation, which not only prevents unstable factors caused by friction braking, but also ensures the service life of the motor and the safety of operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] Figure 1-Figure 3A wind turbine winch arm limiting device includes a base 1 and a transmission device 3. The transmission device 3 is a prior art and is composed of a box, a transmission belt, and two turntables. By driving one turntable to rotate, the rotation of one turntable will drive the other turntable to rotate through the transmission belt, thereby achieving transmission. The upper end of the base 1 is fixedly connected to a motor 2. The motor 2 serves as a driving power source. One side of the motor 2 is provided with two fixed plates 5 fixedly connected to the upper end of the base 1. The two fixed plates 5 are used to provide support. The same reel 4 is installed between the two fixed plates 5. The reel 4 is used to reel in the rope part of the anchor. Both ends of the reel 4 are fixedly connected to a transmission shaft 10. One of the transmission shafts 10 passes through a fixed plate 5 and is connected to the output of the motor 2 through the transmission device 3. The output shaft end is connected, and when the motor 2 rotates, it will drive the transmission shaft 10 to rotate through the transmission device 3, and then drive the reel 4 to rotate. Another transmission shaft 10 passes through another fixed plate 5 and is fixedly sleeved with a brake disc 9. When the brake disc 9 is braked, the transmission shaft 10 connected to the brake disc 9 is braked synchronously, thereby braking the reel 4. A plurality of holes 11 are provided on the circumferential surface of the brake disc 9. A fixed frame 6 connected to the fixed plate 5 is provided on one side of the brake disc 9, and an observation window 12 is provided on one side of the fixed frame 6. The observation window 12 is used to observe whether the brake disc 9 stops rotating. Glass is embedded in the observation window 12. The glass material has good hardness while ensuring transparency. A fixing component connected to the hole slot 11 is connected to the outer wall of the fixed frame 6.
[0022] The fixing assembly includes a rotating shaft 13 rotatably connected to the outer wall of the fixed frame 6, one end of the rotating shaft 13 is fixedly connected to the rotating frame 14, and the rotating frame 14 can rotate around the rotating shaft 13, and the rotating frame 14 is provided with a plug post 15 that matches the size of the hole slot 11 on one side of the rotating frame 6. A through slot opening that matches the size of the plug post 15 is opened on one side of the fixed frame 6, one end of the plug post 15 passes through the rotating frame 14 and is fixedly connected to a handle, and the handle is used to assist in the extraction of the plug post 15
[0023] The brake assembly includes a hydraulic rod 7 fixedly connected to the upper end of the base 1. The telescopic end of the hydraulic rod 7 extends to the inside of the fixed frame 6. One end of the extended hydraulic rod 7 is fixedly connected to a brake pad 8 that matches the outer diameter of the brake disc 9. When the brake pad 8 is lifted by the hydraulic rod 7, it will contact the brake disc 9, thereby friction braking.
[0024] When the utility model is used, the worker first throws the anchor into the sea, and then the connected rope will drive the reel 4 to rotate. When the anchor touches the bottom, the hydraulic rod 7 is driven to lift the brake pad 8 and then contact the brake disc 9, so that the brake disc 9 stops rotating by friction, and the reel 4 is indirectly stopped by the transmission shaft 10, thereby preventing the motor 2 from rotating and affecting its service life. Then, the column 15 can be pulled out of the through-slot on the fixed frame 6 by pulling the handle. At this time, the column 15 can be rotated. When the column 15 is rotated to a certain angle, under the action of the spring 17, the plug-in end of the column 15 will be inserted into a hole groove 11, thereby completely fixing the brake disc 9 and preventing it from rotating.
