Description

Technical Field

[0001] This utility model relates to the field of anchor winches, specifically a marine safety anchor winch. Background Technology

[0002] Anchor winches are deck machinery on ships used for raising and dropping anchors and winch cables. They mainly consist of a power system, transmission system, winch section, control system, and braking system. Their braking performance is directly related to the operational safety of the ship. Most existing anchor winches typically use a single brake band wrapped around the outside of the winch when braking. The brake band is tightened by levers or hydraulic mechanisms to achieve friction with the winch.

[0003] However, this single-sided braking method has obvious drawbacks: on the one hand, the contact wrap angle between the brake band and the winch is limited, resulting in a small effective friction area and insufficient braking torque. Especially when encountering rapid currents or heavy-load anchoring, it often cannot stop the winch rotation in a timely and effective manner, which can easily lead to anchor slippage accidents. On the other hand, single-sided force can easily cause the winch bearing to be subjected to a large radial load, which will accelerate bearing wear and affect the equipment lifespan in the long run.

[0004] Therefore, there is an urgent need for a marine safety anchor winch with a large braking contact area, uniform force distribution, and rapid response. Utility Model Content

[0028] Please see Figure 1-4 This utility model provides an embodiment of a marine safety anchor winch: A marine safety anchor winch includes a mounting platform 1 and a winch 2. The mounting platform 1 includes a support base 101 and a housing 102. The support base 101 is located on one side of the top of the mounting platform 1. Two sets of housings 102 are symmetrically arranged on the top of the mounting platform 1. The support base 101 can support one end of the rotating shaft 201. The winch 2 includes a brake strip 204, a brake pad 205, a servo motor 206, and a bidirectional screw 207. The brake strip 204 is located at the top and bottom of the housing 102. The brake pad 205 is located at one end of the brake strip 204. The servo motor 206 is located at the front end of the top of the housing 102. The bidirectional screw 207 is located at the output end of the servo motor 206, and the bottom end of the bidirectional screw 207 extends through to... Inside the brake strip 204, the positive and negative threads at both ends of the double-ended screw 207 on the outside can adjust the two sets of brake strips 204 in opposite directions, which facilitates quick braking of the winch. The limiting rod 208 is located at the rear end inside the housing 102 and extends into the interior of the brake strip 204, making the adjustment of the two sets of brake strips 204 more stable. Both ends of the winch 2 are equipped with brake wheels 202 inside the housing 102. The two sets of brake wheels 202 and the winch 2 are integrally formed, increasing the friction between the braking mechanism and the brake wheels 202, which facilitates quick braking of the winch. Both sets of brake wheels 202 are equipped with brake rings 203 on the outside. The middle position inside the winch 2 is equipped with a rotating shaft 201 that extends into the support base 101, making the rotation of the winch 2 more stable.

[0029] Please refer to this carefully. Figure 1 and Figure 3 A reducer 3 is provided on the side of the top of the mounting platform 1 away from the support base 101. A rotating motor 301 is installed at the front end of one side of the reducer 3. The rotating motor 301 and the reducer 3 provide power for the rotation of the anchor winch.

[0030] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4Both sides of the housing 102 are equipped with sealing rings to seal the housing 102 and protect the brake assembly. A speed sensor is located on one side of the support base 101 to monitor the speed of the winch 2 in real time. A control module is located at the bottom of one side of the support base 101. The brake pad 205 is connected to the brake strip 204 by bolts, allowing for replacement of the brake pad 205. A bearing is located at the bottom inside the housing 102, and a bidirectional screw 207 passes through the bearing to ensure more stable rotation of the bidirectional screw 207. The servo motor 206 is installed by bolts... The servo motor 206 is connected to the housing 102 and installed on the top of the housing 102. According to the specifications of the anchor winch, a drive motor with appropriate power can be selected for use. One end of the brake strip 204 has a threaded hole that matches the bidirectional screw 207, which serves as a limit adjustment. The two sets of brake strips 204 can be adjusted in opposite directions to increase the contact area between the brake assembly and the brake ring 203. The other end of the brake strip 204 has a limit hole. The brake strip 204 is movably connected to the limit rod 208 through the limit hole, making the adjustment of the brake strip 204 more stable.

[0031] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The support base 101 has a bearing at its top, and one end of the rotating shaft 201 passes through the bearing, making the rotation of the rotating shaft 201 more stable. The winch 2 is rotatably connected to the support base 101 through the rotating shaft 201 and the bearing. The brake wheel 202 has multiple sets of limiting grooves on its outer side, and the brake ring 203 has multiple sets of limiting blocks on its inner side. The brake ring 203 is detachably connected to the brake wheel 202 through the limiting grooves and limiting blocks, so that the brake ring 203 can be limited and installed on the outer side of the brake wheel 202, which facilitates braking of the winch. The other end of the rotating shaft 201 is connected to the reducer 3. The rotating shaft 201 is connected to the reducer 3 through the rotating motor 301 to realize the transmission of power, which facilitates the control and adjustment of the rotation speed of the winch 2.

[0032] Working Principle: When using this invention, power is connected, one end of the cable is fixed to the outside of the winch 2, and the rotating motor 301 is started. The rotating motor 301 reduces the speed and increases the torque through the reducer 3, and drives the winch 2 to rotate through the rotating shaft 201, thereby performing cable winding or unwinding operations. During this process, the speed sensor set on one side of the support base 101 monitors the speed signal of the winch 2 in real time and transmits the signal to the control module. If the speed sensor detects that the speed is greater than the preset standard speed, the control module automatically sends a signal to control the servo motor 206 to start. The servo motor 206 drives the bidirectional screw 207 to rotate. Since the two ends of the bidirectional screw 207 have threads with opposite directions of rotation, and are respectively connected to two sets of screw threads at the top and bottom of the housing 102. The brake strips 204 are threaded. Under the guidance and limiting action of the limiting rod 208, the rotation of the bidirectional screw 207 drives the two sets of brake strips 204 to move in opposite directions vertically inside the housing 102. The brake strips 204 drive the brake pads 205 at their ends to press inward synchronously, so that the brake pads 205 are tightly fitted and fixed to the brake ring 203 on the outside of the brake wheel 202. As the degree of compression increases, the contact area and friction between the brake pads 205 and the brake ring 203 increase rapidly, thereby applying a huge braking torque to the winch 2, realizing rapid braking of the winch 2, effectively avoiding the occurrence of dangerous accidents, and improving the safety of the anchor winch. When the fault is cleared or the braking needs to be released, the servo motor 206 reverses, driving the brake strips 204 to reset and separate.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model.
