An anchoring structure, an anchor winch based on this structure, and a usage method

Abstract

The present invention relates to the technical field of windlasses, and discloses an anchoring structure, a windlass based on this structure and a usage method. Through the setting of the connection component, when it is necessary for the windlass to simultaneously retrieve the ship anchor and the cable, the crew uses the lever to push the engagement shaft to dock with the engagement disc of the winch, becoming an integral whole. So that when the windlass drives the winch to rotate and retrieve the anchor chain, it can also synchronously drive the auxiliary drum to rotate, enabling the auxiliary drum to retrieve the cable. When it is necessary for the windlass to separately retrieve the ship anchor or the cable, the crew uses the lever to push the connecting shaft to separate from the engagement disc of the winch, making the winch and the auxiliary drum independent of each other, and capable of separately retrieving the ship anchor or the cable. Thus, the windlass can be applied to various situations, improving the applicability of the device.

Description

Technical Field

[0001] The present invention relates to the technical field of windlasses, and particularly to an anchoring structure, a windlass based on this structure, and a usage method. Background Art

[0002] A windlass is a mechanical device on a ship for retrieving and paying out an anchor and its chain. It can use manpower, steam engine, electric motor, or hydraulic motor as a power source to enable a single unit to complete functions such as weighing anchor and mooring.

[0003] On traditional windlasses, the drum for retrieving mooring ropes and the capstan for retrieving the anchor chain are integrally connected. When the capstan rotates, it will drive the drum to rotate together, thereby retrieving the anchor chain and the mooring ropes simultaneously. However, sometimes when a ship temporarily docks at the shore for a quick departure, only the mooring ropes are used to dock the ship at the shore, and the ship anchor is not used for docking. At this time, the traditional windlass cannot make the drum rotate independently to retrieve the mooring ropes. Summary of the Invention

[0008] Preferably, the connecting assembly further includes pulleys. All four pulleys are rotatably connected inside the installation groove, and each pulley corresponds to one of the receiving grooves respectively.

[0009] Preferably, the locking block is slidably installed inside the receiving groove. A support spring is fixedly connected between the top of the locking block and the inner wall of the receiving groove. When the locking block is located above the locking groove, the support spring pushes the locking block into the locking groove.

[0010] Preferably, a fixed sleeve is fixedly connected to the top of the locking block. The fixed sleeve is located inside the support spring. One end of a steel cable is fixedly connected inside the fixed sleeve. The other end of the steel cable bypasses the pulley and is fixedly connected to the inside of the runner. The runner is rotatably installed on the engaging shaft.

[0011] Preferably, the winding mechanism further includes a driving motor and a support base. The driving motor is fixedly installed on the base. The driving motor is located on the side of the winch far from the auxiliary drum. A transmission shaft is fixedly connected to the winch coaxially. The transmission shaft is connected to the driving motor. The support base is fixedly installed on the base. The support base is located on the side of the winch close to the auxiliary drum.

[0015] Compared with the prior art, the present invention provides an anchoring structure, an anchor winch based on this structure, and a usage method, which have the following beneficial effects:

[0016] 1. For the anchoring structure, the anchor winch based on this structure, and the usage method, through the setting of the connection component, when the anchor winch needs to retract the ship anchor and the cable at the same time, the crew member pushes the engagement shaft against the engagement disk of the winch through the lever to be docked into a whole. When the anchor winch drives the winch to rotate and retracts the anchor chain, it can also synchronously drive the secondary drum to rotate, so that the secondary drum retracts the cable. When the anchor winch needs to retract the ship anchor or the cable alone, the crew member pushes the connecting shaft against the engagement disk of the winch through the lever to separate, so that the winch and the secondary drum are independent of each other and can retract the ship anchor or the cable separately. Therefore, the anchor winch can be applied to various situations, improving the applicability of the device.

[0017] 2. For the anchoring structure, the anchor winch based on this structure, and the usage method, through the setting of the locking component, when the engagement shaft is in the separated state or in the docked state with the engagement disk, the support spring will push the locking block out of the receiving groove and insert it into the locking groove, thereby fixing the engagement shaft on the connecting shaft. When the device is running, the engagement shaft will not move freely on the connecting shaft, thus ensuring the stable operation of the device. And when it is necessary to release the locking of the engagement shaft by the locking component, only by rotating the rotating ring can the operation be completed. After the engagement shaft moves to the corresponding position and the rotating ring is released, the locking block can be automatically locked under the action of the support spring, making the operation of the device very convenient.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] Please refer to Figures 1-8, An anchoring structure, an anchor winch based on this structure and a usage method, which includes a base 1. A cable winding mechanism 2, a connection component 4, a locking component 5 and a brake component 6 are arranged on the base 1. The cable winding mechanism 2 includes a winch 22 for winding and unwinding the anchor chain and an auxiliary drum 3 for winding and unwinding the cable. The winch 22 and the auxiliary drum 3 are sequentially installed on the base 1. A connecting shaft 31 is installed on the auxiliary drum 3. Two locking grooves 312 are sequentially formed at one end of the connecting shaft 31 facing the winch 22. A joint disc 222 is connected to one side of the winch 22 facing the auxiliary drum 3. The connection component 4 includes a joint shaft 41. The joint shaft 41 is installed at one end of the connecting shaft 31 close to the winch 22. The joint shaft 41 can move on the connecting shaft 31 towards the joint disc 222 to dock with the joint disc 222, so that the auxiliary drum 3 can rotate following the winch 22. The locking component 5 includes a locking block 51 and a runner 55. The locking block 51 is installed inside the joint shaft 41. The top of the locking block 51 is connected to the inner wall of the runner 55. The runner 55 is installed on the joint shaft 41. When the joint shaft 41 is not docked with the joint disc 222, the locking block 51 is inserted into the locking groove 312 on the connecting shaft 31 far from the joint disc 222. By rotating the runner 55, the locking block 51 can be withdrawn from the locking groove 312. When the joint shaft 41 is docked with the joint disc 222, the locking block 51 is inserted into the locking groove 312 close to the joint disc 222. A brake component 6 is installed on the side of the winch 22. The brake component 6 can brake the winch 22 when the winch 22 rotates.

[0030] Among them, during use, the winch 22 is in a separated state from the auxiliary drum 3 in the initial state, and the engagement shaft 41 of the connection assembly 4 is not docked with the engagement disc 222 on the winch 22. When the ship docked at the shore needs to set sail with the cooperation of the ship anchor and the cable, the crew first rotates the runner 55 in the reverse direction, and extracts the locking block 51 inserted into the locking groove 312 near the auxiliary drum 3 through the runner 55, thereby releasing the locking of the locking assembly 5 on the engagement shaft 41. Subsequently, by pushing the engagement shaft 41 towards the engagement disc 222, the engagement shaft 41 is docked with the engagement disc 222. At this time, the runner 55 is released, and the locking block 51 is inserted into the locking groove 312 near the winch 22 to fix the engagement shaft 41, enabling the winch 22 to drive the auxiliary drum 3 to operate stably. After the connection between the winch 22 and the auxiliary drum 3 is completed, the windlass is started, and the winch 22 drives the auxiliary drum 3 to rotate synchronously in the reverse direction. During this process, the rotating winch 22 will take in the thrown anchor chain, and the rotating auxiliary drum 3 will take in the thrown cable. After the anchor chain and the cable are taken in, the crew promptly brakes the winch 22 through the braking assembly 6 to prevent the winch 22 from continuing to rotate and damaging the equipment. The windlass ends its work, and the winch 22 and the auxiliary drum 3 stop rotating. At this time, the crew rotates the runner 55 again, extracts the locking block 51 inserted into the locking groove 312 near the winch 22, and pushes the engagement shaft 41 towards the auxiliary drum 3 to move away from the engagement disc 222, thereby ending the docking of the engagement shaft 41 and the engagement disc 222. When the engagement shaft 41 moves to the position where it was in the initial separated state, the runner 55 is released, and the locking block 51 is inserted into the locking groove 312 near the auxiliary drum 3 again to lock the engagement shaft 41 on the connecting shaft 31, waiting for the next use. In the case where the ship docks using only the anchor chain or the cable, when taking in the anchor chain, the winch 22 and the auxiliary drum 3 are kept in a separated state, and the windlass only drives the winch 22 to rotate to take in the anchor chain. Or when taking in the cable, the crew manually rotates the auxiliary drum 3 to take in the cable, enabling the windlass to take in the anchor chain and the cable in various situations, thereby improving the adaptability of the windlass.

[0031] The difference from the above embodiment is that the connecting shaft 31 is coaxially and fixedly connected to the auxiliary drum 3, and both ends of the connecting shaft 31 extend from both sides of the auxiliary drum 3 respectively. Four limiting blocks 311 are fixedly connected to the outer surface of the end of the connecting shaft 31 close to the winch 22. The four limiting blocks 311 are evenly distributed in a circular shape on the connecting shaft 31. The locking groove 312 is opened on the limiting block 311, and two locking grooves 312 are sequentially opened on each limiting block 311. A handwheel 32 is fixedly connected to the end of the connecting shaft 31 far from the winch 22, and the handwheel 32 can drive the auxiliary drum 3 to rotate.

[0032] Among them, when it is necessary to separately use the auxiliary drum 3 to wind the cable, the winch 22 is kept separated from the auxiliary drum 3, and the crew drives the auxiliary drum 3 on the connecting shaft 31 to rotate in the reverse direction through the handwheel 32, so as to wind the cable.

[0033] The difference from the above embodiment is that a sliding groove 411 is formed in the engaging shaft 41, the opening of the sliding groove 411 is arranged at the other end of the engaging shaft 41, the engaging shaft 41 is fitted on the connecting shaft 31 through the sliding groove 411, four receiving grooves 412 are formed in the engaging shaft 41, the receiving grooves 412 correspond to the limiting blocks 311, an installation groove 413 and an annular groove 414 are sequentially formed on the outer side of the engaging shaft 41, the installation groove 413 is located above the receiving groove 412, and the annular groove 414 is located at one end of the engaging shaft 41 close to the auxiliary drum 3.

[0034] Among them, through the cooperation of the limiting block 311 and the sliding groove 411, the engaging shaft 41 can only perform linear motion on the connecting shaft 31, so that the locking block 51 can accurately insert into the locking groove 312, ensuring the stable operation of the equipment.

[0035] The difference from the above embodiment is that the connecting assembly 4 further includes pulleys 42, and the four pulleys 42 are all rotatably connected in the installation groove 413, and each pulley 42 corresponds to a receiving groove 412 respectively.

[0036] The difference from the above embodiment is that the locking block 51 is slidably installed in the receiving groove 412, a support spring 52 is fixedly connected between the top of the locking block 51 and the inner wall of the receiving groove 412, and when the locking block 51 is located above the locking groove 312, the support spring 52 pushes the locking block 51 to insert into the locking groove 312.

[0037] The difference from the above embodiment is that a fixed sleeve 53 is fixedly connected to the top of the locking block 51, the fixed sleeve 53 is located inside the support spring 52, one end of the steel cable 54 is fixedly connected inside the fixed sleeve 53, the other end of the steel cable 54 bypasses the pulley 42 and is fixedly connected to the inside of the runner 55, and the runner 55 is rotatably installed on the engaging shaft 41.

[0038] In the initial separation state, the support spring 52 pushes the locking block 51 out of the receiving groove 412, so that the locking block 51 is inserted into the locking groove 312, the engaging shaft 41 is locked, and the steel cable 54 wound around the pulley 42 is pulled to make the rotating wheel 55 move to the corresponding position. When the lock needs to be released, the crew rotates the rotating wheel 55 in the opposite direction, so that the steel cable 54, with the assistance of the pulley 42, pulls the locking block 51 out of the locking groove 312, retracts it into the receiving groove 412, and compresses the support spring 52, wherein the fixing sleeve The cylinder 53 protects the steel cable 54 in the storage groove 412, preventing the steel cable 54 from being entangled with the support spring 52, thereby affecting the normal operation of the equipment. After the coupling shaft 41 is docked with the coupling disk 222, the crew releases the rotating wheel 55, and the compressed support spring 52 recovers its deformation to push the locking block 51 out of the storage groove 412, so that the locking block 51 is inserted into the corresponding locking groove 312, and the locking block 51 inserted into the locking groove 312 will pull the steel cable 54, so that the rotating wheel 55 rotates forward and swings back to its original position.

[0039] The difference from the above embodiment is that the collecting mechanism 2 also includes a driving motor 21 and a support seat 23. The driving motor 21 is fixedly mounted on the base 1, and the driving motor 21 is located on the side of the capstan 22 away from the auxiliary drum 3. A transmission shaft 221 is coaxially fixedly connected to the capstan 22, and the transmission shaft 221 is connected to the driving motor 21. The support seat 23 is fixedly mounted on the base 1, and the support seat 23 is located on the side of the capstan 22 close to the auxiliary drum 3. The end of the connecting shaft 31 close to the capstan 22 is rotatably mounted on the support seat 23.

[0040] When the winch 22 needs to be rotated, the crew starts the drive motor 21 to drive the winch 22 to rotate forward or reverse.

[0041] The difference from the above-mentioned embodiment lies in that a support platform 231 extending toward the winch 22 is fixedly mounted on one side of the upper end of the support seat 23, and a lever 232 is rotatably connected to the support platform 231, one end of the lever 232 is located above the coupling shaft 41, and a protruding rod 2321 is also fixedly connected to the end of the lever 232, and the protruding rod 2321 extends into the annular groove 414, and there is a gap between the protruding rod 2321 and the inside of the annular groove 414.

[0042] Among them, when the coupling shaft 41 is docked with the coupling disk 222, after the locking assembly 5 is unlocked, the crew member pulls the lever 232 in the direction of the secondary drum 3, so that the lever 232 pushes the coupling shaft 41 to move toward the coupling disk 222 through the convex rod 2321 to complete the docking. After the coupling shaft 41 is docked with the coupling disk 222, since there is no gap between the convex rod 2321 and the inside of the annular groove 414, when the capstan 22 drives the secondary drum 3 to rotate through the connecting assembly 4, the rotation of the coupling shaft 41 will not be affected by the convex rod 2321. When the coupling shaft 41 is separated from the coupling disk 222, after the locking assembly 5 is unlocked, the crew member pulls the lever 232 in the direction of the coupling disk 222, so that the lever 232 pushes the coupling shaft 41 to move toward the secondary drum 3 through the convex rod 2321 to complete the separation.

[0043] Embodiment 2

[0044] The difference from the above embodiment is that the brake assembly 6 includes an arc-shaped brake pad 61, a main connecting rod 62 and a secondary connecting rod 63. The two arc-shaped brake pads 61 are rotatably connected and are installed in a circular ring shape on one side of the capstan 22 close to the secondary drum 3. The end of the arc-shaped brake pad 61 located at the top is rotatably connected to the lower end of the main connecting rod 62, and the end of the arc-shaped brake pad 61 located at the bottom is rotatably connected to one end of the secondary connecting rod 63, and the other end of the secondary connecting rod 63 is rotatably connected to the lower end of the main connecting rod 62. The upper end of the main connecting rod 62 is equipped with a brake screw 64, and the threaded section of the brake screw 64 is connected to the arc-shaped brake pad 61 located at the top. By rotating the brake screw 64, the main connecting rod 62 can be driven to move, and the main connecting rod 62 can drive the secondary connecting rod 63. The end of the arc-shaped brake pad 61 located at the top is also rotatably connected to the upper end of the connecting rod 65, and the connecting rod 65 passes through the secondary connecting rod 63. The lower end of the connecting rod 65 is rotatably connected to the base 1.

[0045] Among them, when the brake assembly 6 is needed to brake the capstan 22, the crew can rotate the brake screw 64 in the reverse direction to make the brake screw 64 bring the main connecting rod 62 closer to the capstan 22, thereby pulling up the secondary connecting rod 63, so that the two elastic arc-shaped brake pads 61 installed on the side of the capstan 22 are tightened to brake the capstan 22. After the capstan 22 is braked, the crew rotates the brake screw 64 forward again to make the brake screw 64 bring the main connecting rod 62 away from the capstan 22, thereby resetting the main connecting rod 62, and the tightened arc-shaped brake pads 61 are reset under the action of elasticity, thereby ending the braking of the capstan 22 and pulling down the secondary connecting rod 63.

[0046] The invention also provides a method of use, which uses an anchoring structure and an anchor windlass based on the structure.

[0047] Working principle: When in use, the capstan 22 and the auxiliary drum 3 are separated in the initial state, and the coupling shaft 41 of the connecting assembly 4 is not connected with the coupling plate 222 on the capstan 22. At this time, the supporting spring 52 pushes the locking block 51 to extend out of the storage groove 412, so that the locking block 51 is inserted into the locking groove 312, the coupling shaft 41 is locked, and the steel cable 54 wound around the pulley 42 is pulled to make the rotating wheel 55 move to the corresponding position. With the cooperation of the anchor and the cable, when the ship docked at the shore needs to set sail, the crew rotates the rotating wheel 55 in the opposite direction, so that the steel cable 54, with the assistance of the pulley 42, pulls the locking block 51 out of the locking groove 312. The locking block 51 is pushed out and retracted into the receiving groove 412, and the supporting spring 52 is compressed, thereby releasing the locking assembly 5 from locking the engaging shaft 41. Then, the crew member pulls the lever 232 toward the auxiliary drum 3, and the lever 232 pushes the engaging shaft 41 toward the engaging plate 222 through the convex rod 2321, so that the engaging shaft 41 and the engaging plate 222 are docked together. At this time, the rotating wheel 55 is released again, and the compressed supporting spring 52 recovers its deformation to push the locking block 51 out of the receiving groove 412, so that the locking block 51 is inserted into the corresponding locking groove 312, and the locking block 51 inserted into the locking groove 312 pulls the steel cable 54, so that the rotating wheel 55 rotates forward and swings back to its original position.

[0048] After completing the connection between the capstan 22 and the auxiliary drum 3, the anchor windlass is started, and the driving motor 21 causes the capstan 22 to drive the auxiliary drum 3 to rotate in the opposite direction synchronously. During this process, the rotating capstan 22 will collect the thrown anchor chain, and the rotating auxiliary drum 3 will collect the thrown cable. After completing the collection of the anchor chain and cable, the crew can stop the capstan 22 in time through the brake assembly 6, wherein the crew can reversely rotate the brake screw 64 to make the brake screw 64 bring the main connecting rod 62 closer to the capstan 22, thereby The secondary connecting rod 63 is pulled upwards, so that the two elastic arc-shaped brake pads 61 installed on the side of the capstan 22 are tightened, and the capstan 22 is braked. After the capstan 22 is braked, the crew rotates the brake screw 64 forwardly, so that the brake screw 64 takes the main connecting rod 62 away from the capstan 22, so that the main connecting rod 62 is reset, and the tightened arc-shaped brake pads 61 are reset under the action of elasticity, thereby ending the braking of the capstan 22, and pulling down the secondary connecting rod 63, then the windlass ends the work, and the capstan 22 and the secondary drum 3 stop rotating;

[0049] At this time, the crew rotates the runner 55 again, pulls out the locking block 51 inserted in the locking groove 312 near the winch 22, and pushes the engaging shaft 41 towards the auxiliary drum 3, away from the engaging disc 222, thus ending the docking of the engaging shaft 41 and the engaging disc 222. When the engaging shaft 41 moves to the position where it was in the initial separated state, the runner 55 is released, and the locking block 51 is inserted into the locking groove 312 near the auxiliary drum 3 again to lock the engaging shaft 41 on the connecting shaft 31, waiting for the next use. In the case where the ship docks using only the anchor chain or cable, when retrieving the anchor chain, the winch 22 and the auxiliary drum 3 are kept in a separated state, and the windlass only drives the winch 22 to rotate to retrieve the anchor chain. Or when retrieving the cable, the crew manually rotates the auxiliary drum 3 through the handwheel 32 to retrieve the cable, enabling the windlass to retrieve the anchor chain and cable under various conditions, thereby improving the adaptability of the windlass.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
