Description

Technical Field

[0001] This utility model relates to the field of marine technology, specifically to a ship's anchor winch limiting device. Background Technology

[0002] Anchor winches are key equipment for anchoring and mooring operations. Existing anchor winches typically rely on motor brakes or simple pins for limiting the movement after the anchor chain is wound or released.

[0003] However, in the harsh marine environment, the ship's hull rolls violently, and a single braking method is prone to failure due to insufficient braking force or mechanical fatigue, causing the anchor chain to slip unexpectedly. In addition, the traditional pin-locking operation is cumbersome, requiring manual alignment of the pin hole, which is time-consuming, labor-intensive, and poses safety hazards. At the same time, the rigid locking structure lacks cushioning and is easily damaged when subjected to huge waves. Therefore, it is particularly important to design an anchor winch limiting device that is easy to operate, has a cushioning function, and has reliable locking. Utility Model Content

[0030] The base 101 and the support plate 102 are arranged perpendicularly to each other, and the fixed roller 103 and the base 101 are arranged parallel to each other.

[0031] The fixed roller 103 is fixedly connected to the connecting column 104, the left connecting column 104 is rotatably connected to the bearing 105, and the right connecting column 104 is fixedly connected to the output end of the servo motor 106.

[0032] Example 2:

[0033] This utility model also provides another solution. Based on the first embodiment, the storage box 201 and the guide block 202 are fixedly connected, while the guide block 202 and the guide groove 203 are slidably connected. This ensures the storage box 201 moves vertically and smoothly downwards, avoiding tilting or jamming and improving operational stability. The middle positions of the guide block 202, the guide block 202, and the support plate 102 are on the same horizontal line. The storage box 201 and the fixing groove 205 are integrated, and the fixing groove 205 and the connecting column 104 are correspondingly arranged. The storage box 201 and the insertion rod 206 are fixedly connected, and the insertion rod 206 and the slot 207 are correspondingly arranged. The support column 208 is fixedly connected to the bottom of the storage box 201 and the top of the connecting plate 209. The connecting plate 209 is slidably connected to the slide 210. The slide 210 is integrated with the base 101. The push-type buckle 212 and the push-type slot 213 are engaged. The limit and lock can be completed by manual pressing, which is suitable for rapid operation in harsh marine environments and improves work efficiency. The telescopic spring 211 is fixedly connected to the bottom of the connecting plate 209 and the inner side of the base 101. The telescopic spring 211 provides a buffering effect during the pressing process to avoid impact or deformation of the mechanism due to sudden force and extend the service life of the equipment.

[0034] Working principle:

[0035] When using this device, first start the servo motor 106 to drive the connecting column 104 and the fixed roller 103 to rotate. The anchor chain is then introduced through the fixing port 204 and wound onto the fixed roller 103 for winding. At this time, the storage box 201 is in a high position under the action of the telescopic spring 211, and the insertion rod 206 is separated from the slot 207 on the connecting column 104, without interfering with each other. When the anchor chain is wound up and needs to be locked, the servo motor 106 stops working, and the operator manually presses down on the storage box 201, causing the guide blocks 202 on both sides of the storage box 201 to slide vertically downwards along the guide groove 203 on the inner side of the support plate 102. Simultaneously, this causes the bottom support column 208 and the connecting plate 209 to move downwards within the sliding groove 210 of the base 101 and compress the telescopic spring 211. During the pressing process, if the insertion rod 206 and the slot 207 are not fully engaged... To align, the angle of the fixed roller 103 can be finely adjusted by jogging the servo motor until the insertion rod 206 is smoothly inserted into the slot 207 on the connecting column 104. Then, continue pressing down until the push-type buckle 212 at the bottom of the connecting plate 209 engages in the push-type slot 213 to complete the locking. At this time, the rigid cooperation between the insertion rod 206 and the slot 207 restricts the rotation of the fixed roller 103, preventing the anchor chain from slipping off. When under force, the telescopic spring 211 can absorb the vibration energy generated by the impact of wind and waves. When it is necessary to unlock for the next operation, simply press down on the storage box 201 again to trigger the release mechanism of the push-type buckle 212, causing it to disengage from the push-type slot 213. Then, under the restoring force of the telescopic spring 211, the storage box 201 automatically bounces up to reset, driving the insertion rod 206 out of the slot 207 and releasing the lock on the fixed roller 103.
