Description

Technical Field

[0001] The present application relates to the technical field of ship unanchoring, and in particular to an anchor locking and unhooking method based on angle locking. Background Art

[0002] The anchor lock and release hook is used to lock the anchor. When the ship needs to anchor, the anchor lock and release hook is released, the anchor is detached and slides into the water under the action of gravity to anchor the ship.

[0003] In the related art, when performing anchoring operations, the anchor locking and unhooking based on angle locking requires personnel to push forward to unlock the anchor locking and unhooking and release the anchor. However, when the personnel push forward to unhook the anchor, the anchor chain slides down quickly, which can easily injure the operator. On the other hand, the current anchor locking and unhooking method is single. If the manual unhook force is insufficient, there is a lack of subsequent unhook processing methods. Therefore, how to perform unhook operations in a safe position and increase unhook methods have become technical problems that need to be solved. Summary of the Invention

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] The following describes the anchor locking and unhooking method based on angle locking according to an embodiment of the present application with reference to the accompanying drawings.

[0024] See also Figures 1 to 8 According to an embodiment of the present application, the anchor locking and unhooking system based on angle locking includes: a base structure 100, a swing-type unhooking structure 200, an angle locking structure 300 and a double-force unhooking structure 400.

[0025] See also Figure 1The swing-type unhooking structure 200 is arranged at the front end of the base structure 100, and the main hook part of the swing-type unhooking structure 200 is rotatably arranged at the front end of the swing-type unhooking structure 200; the angle locking structure 300 is arranged inside the upper end of the swing-type unhooking structure 200, and the angle locking structure 300 swings forward and downward under the action of gravity. After the angle locking structure 300 swings and falls, the bottom end of the angle locking structure 300 is stuck with the rear end of the main hook part of the swing-type unhooking structure 200; the double-force unlocking structure 400 is arranged at the rear end of the swing-type unhooking structure 200, and the double-force unlocking structure 400 is connected to the middle part of the angle locking structure 300. The double-force unlocking structure 400 can pull the angle locking structure 300 to swing backward and upward by manpower and the pull rope. The double-force unlocking structure 400 can also pull the angle locking structure 300 to swing backward and upward by power, and release the locking of the main hook part of the swing-type unhooking structure 200 by the angle locking structure 300 by both manpower and power. The operator remotely pulls the rope to swing the upper end of the dual-force release mechanism 400 backward. This causes the lower end of the angle locking mechanism 300 to swing backward, allowing the lower end of the angle locking mechanism 300 to move away from the rear end of the main hook of the swing-type unhooking mechanism 200. This releases the lock of the angle locking mechanism 300 from the swing-type unhooking mechanism 200. The main hook of the swing-type unhooking mechanism 200 then swings forward under the action of gravity, releasing the lock of the main hook of the swing-type unhooking mechanism 200 from the anchor. The anchor then slides into the water under the action of gravity, thus anchoring the ship. This achieves the purpose of manual release, and the operator can remotely release the anchor by pulling the rope, reducing the risk of the anchor chain slipping and injuring the operator. On the other hand, when manual unlocking is insufficient due to excessive friction between the main hook part of the swing-type unhooking structure 200 and the angle locking structure 300, the angle locking structure 300 is pulled by power to swing backward and upward, and the lower end of the angle locking structure 300 leaves the rear end of the main hook part of the swing-type unhooking structure 200, so that the angle locking structure 300 releases the lock on the swing-type unhooking structure 200, thereby releasing the anchor and completing the ship anchoring work. When the manual unlocking force is insufficient, the anchor can also be unhooked by power, so as to smoothly complete the unhooking work.

[0026] See also Figures 1 to 2The base structure 100 includes a fixed base 110, slide rails 120, a movable base 130, and a fixed plate 140. The slide rails 120 are fixedly connected to both sides of the fixed base 110. The movable base 130 is slidably connected between the slide rails 120. The swing-type unhooking structure 200 is installed at the front end of the movable base 130, and the fixed plate 140 is fixedly connected to the rear end of the movable base 130. The power application part of the dual-force release structure 400 is connected to the fixed plate 140. The movable base 130 slides along the slide rails 120 to adjust the position of the swing-type unhooking structure 200, so that the released anchor can slide smoothly into the water for ship anchoring operations.

[0027] See also Figures 1 to 3 The swing-type unhooking structure 200 includes a mounting base 210, a swing-type unhooking hook 220, and a main hook pin 230. Two mounting bases 210 are provided, and the two mounting bases 210 are arranged opposite each other at the front end of the base structure 100. The main hook pin 230 extends through the lower sides of the front ends of the two mounting bases 210. The middle portion of the lower end of the swing-type unhooking hook 220 is rotatably sleeved on the main hook pin 230. The bottom end of the angle locking structure 300 is clamped to the upper side of the rear portion of the lower end of the swing-type unhooking hook 220. The mounting base 210 is relatively fixed to the front end of the upper side of the movable base 130. The main hook pin 230 extends out of the front end of the movable base 130, allowing ample room for the swing-type unhooking hook 220 to flip, facilitating unhooking. The swing-type unhooking 220 is the main hook part of the swing-type unhooking structure 200. The lower end of the angle locking structure 300 leaves the upper side of the rear part of the lower end of the swing-type unhooking 220, releasing the lock of the angle locking structure 300 on the swing-type unhooking 220, so that the front end of the swing-type unhooking 220 swings forward around the main hook pin shaft 230 under the action of gravity, so that the anchor leaves the swing-type unhooking 220, thereby achieving the purpose of releasing the anchor.

[0028] See also Figures 1 to 4An anti-tripping mechanism 240 is provided at the upper end of the mounting base 210. The anti-tripping mechanism 240 includes a tripping pin 241, a tripping 242, an elastic metal sheet 243 and a limit block 244. The tripping pin 241 passes through the upper side of the front end of the two mounting bases 210, and the tripping 242 is rotatably connected to the tripping pin 241. The elastic metal sheet 243 is provided on the lower side of the tripping 242. The limit block 244 is fixedly connected to the inner side of the mounting base 210. One end of the elastic metal sheet 243 is pressed against the limit block 244. The elastic force of the elastic metal sheet 243 pushes the tripping 242 to swing upward, and the front end of the tripping 242 can support the inner wall of the upper end of the swing-type unhooking 220. Because the swing-type release hook 220 needs to be hooked to an anchor, when the bottom end of the angle locking structure 300 locks the swing-type release hook 220, an opening for hanging the anchor must be reserved at the top end of the swing-type release hook 220. After the anchor is hooked, the opening must be sealed to prevent the anchor from being dislodged from the opening due to external forces. When the anchor is hooked, the release buckle 242 is forced to swing downward, increasing the elastic force of the elastic metal sheet 243. When the anchor's hooking point passes the release buckle 242, the release buckle 242 is retracted under the elastic force of the elastic metal sheet 243, and the front end of the release buckle 242 presses against the inner wall of the top end of the swing-type release hook 220, thereby sealing the opening at the top end of the swing-type release hook 220. This reduces the possibility of the anchor accidentally detaching from the swing-type release hook 220.

[0029] See also Figures 1 to 5 The swing-type unhooking 220 includes a main hook body 221 and a locking block 222. The lower end of the main hook body 221 is rotatably sleeved on the main hook pin shaft 230. The locking block 222 is fixedly connected to the rear part of the lower end of the main hook body 221. The upper side of the rear end of the locking block 222 is provided with a locking angle 223. The locking angle 223 of the locking block 222 is locked into the bottom end of the angle locking structure 300. The angle between the upper side surface of the locking angle 223 and the contact surface of the angle locking structure 300 is smaller than the self-locking angle. The gravity of the anchor acts on the main hook body 221, causing the main hook body 221 to be subjected to forward pressure. The main hook body 221 tends to swing forward and downward around the main hook pin shaft 230. The locking block 222 and the main hook body 221 are an integrated structure. The locking block 222 tends to move backward and upward. The upper side of the engaging angle 223 of the locking block 222 generates pressure on the contact surface of the angle locking structure 300. Since the angle between the upper side of the engaging angle 223 and the contact surface of the angle locking structure 300 is smaller than the self-locking angle, the angle locking structure 300 and the locking block 222 form an angle lock, so that the greater the force on the main hook body 221, the more stable the locking of the anchor is, reducing the occurrence of accidental unanchoring.

[0030] See also Figures 1 to 6The angle locking structure 300 includes an angle locking member 310 and a connecting ear seat 330. The upper end of the angle locking member 310 is rotatably connected to the upper end of the swing type unhooking structure 200. The lower end of the angle locking member 310 is provided with a snap fit opening 320. The snap fit opening 320 of the angle locking member 310 clamps the rear end of the main hook part of the swing type unhooking structure 200. The front end of the connecting ear seat 330 is rotatably connected to the middle part of the angle locking member 310, and the rear end of the connecting ear seat 330 is rotatably connected to the double-force unhooking structure 400. The upper end of the angle locking member 310 is rotatably connected to the upper ends of the two mounting bases 210, and the engaging opening 320 of the angle locking member 310 is adapted to the engaging angle 223 of the locking block 222. The force exerted by the engaging angle 223 of the locking block 222 on the upper side of the engaging opening 320 of the angle locking member 310 is affected by the self-locking angle of the contact surface, so that an angle self-locking is formed between the angle locking member 310 and the locking block 222, thereby reducing the occurrence of accidental unanchoring.

[0031] See also Figures 1 to 7 The angle locking member 310 includes a locking pin shaft 311 and an angle locking block 312. The locking pin shaft 311 passes through the upper end of the swing-type unhooking structure 200. The upper end of the angle locking block 312 is rotatably connected to the locking pin shaft 311. The front side of the lower end of the angle locking block 312 is provided with a snap fit opening 320. Transition grooves 313 are provided on both sides of the middle part of the angle locking block 312. The front end of the connecting ear seat 330 is rotatably connected to the middle part of the angle locking block 312, and the connecting ear seat 330 can swing in the transition groove 313. When the main hook body 221 returns to its original position under the action of external force, the locking block 222 pushes the angle locking block 312, so that the locking angle 223 of the locking block 222 is automatically engaged with the engaging opening 320 at the lower end of the angle locking block 312, so that the engaging angle 223 and the engaging opening 320 form an angle self-locking, and the return process of the main hook body 221 is simple, reducing the complicated operation of returning the main hook body 221.

[0032] See also Figures 1 to 7 The connecting lug seat 330 includes a connecting pin 331 and a connecting lug plate 332. The front and rear ends of the two connecting lug plates 332 are connected by the connecting pin 331. The connecting pin 331 at the front end of the connecting lug plate 332 rotates and passes through the middle of the angle locking member 310, while the connecting pin 331 at the rear end of the connecting lug plate 332 rotates and passes through the double-force unlocking structure 400. The transition groove 313 provides space for the movement of the connecting lug plate 332. The double-force unlocking structure 400 swings. The double-force unlocking structure 400 drives the connecting pin 331 at the rear end of the connecting lug plate 332. The connecting pin 331 at the rear end of the connecting lug plate 332 drives the connecting lug plate 332. The connecting lug plate 332 drives the connecting pin 331 at the front end of the connecting lug plate 332. The connecting pin 331 at the front end of the connecting lug plate 332 pulls the angle locking block 312 to swing backward and upward against gravity.

[0033] See also Figures 1 to 7 The dual-force release structure 400 includes a dual-force release element 410, a release pin 420, a torsion spring 430, a conductive ear 440, and a drive rod 450. The release pin 420 rotates and extends through the upper side of the rear end of the swing-type release structure 200. The upper side of the rear end of the dual-force release element 410 is rotatably sleeved on the release pin 420. The torsion spring 430 is sleeved on the release pin 420. One end of the torsion spring 430 is connected to the swing-type release structure 200, and the other end of the torsion spring 430 is connected to the dual-force release element 410. The elastic force of the torsion spring 430 can push the upper end of the dual-force release element 410 to swing forward. The front end of the conductive ear 440 is rotatably connected to the lower end of the dual-force release element 410. The drive rod 450 is fixedly connected to the base structure 100, and the rear end of the conductive ear 440 is rotatably connected to the output end of the drive rod 450. The drive rod 450 is configured as an electric push rod. During manual unanchoring, the pull rope applies force to the upper end of the double-force release lock 410, causing the double-force release lock 410 to swing backward. The double-force release lock 410 rotates about the release pin 420. Driven by the double-force release lock 410, the connecting pin 331 at the rear end of the connecting lug 332 swings upward. The connecting lug 332 pulls the lower end of the angle locking block 312 to swing backward about the locking pin 311, causing the engaging opening 320 of the angle locking block 312 to gradually move away from the engaging angle 223 of the locking block 222. It should be noted that during manual unanchoring, the drive rod 450 moves accordingly, and the output end of the drive rod 450 is pulled out as the double-force release lock 410 rotates. The drive rod 450 is fixedly connected to the fixed plate 140, and the output end of the drive rod 450 extends to the front side of the fixed plate 140. When the drive rod 450 is unanchored, the output end of the drive rod 450 is pushed out. This pushes the double-force release member 410 to rotate about the release pin 420 via the conductive ear 440. Driven by the double-force release member 410, the connecting pin 331 at the rear end of the connecting ear plate 332 swings upward. The connecting ear plate 332 pulls the lower end of the angle locking block 312 to swing backward about the locking pin 311, causing the engagement opening 320 of the angle locking block 312 to gradually move away from the engagement angle 223 of the locking block 222. After the human force and the pulling force of the drive rod 450 are released, the double-force release member 410, under the return of the torsion spring 430, pushes the lower end of the angle locking block 312 forward and back to its original position via the connecting pin 331. The angle locking block 312 returns to its original position under the combined forces of gravity and elasticity, reducing the risk of the angle locking block 312 becoming accidentally stuck.

[0034] See also Figures 1 to 8The double-force unlocking component 410 includes a double-force unlocking plate 411 and a pull rod 412. The pull rod 412 is fixedly connected to the upper side of the double-force unlocking plate 411, and the pull rope is fixedly connected to the top of the pull rod 412. A first connecting hole 413 is opened at the front end of the double-force unlocking plate 411, and the rear end of the angle locking structure 300 is rotatably connected to the first connecting hole 413. A second connecting hole 414 is opened on the upper side of the rear end of the double-force unlocking plate 411, and the unlocking pin shaft 420 is rotatably connected to the second connecting hole 414. A third connecting hole 415 is opened on the lower end side of the rear end of the double-force unlocking plate 411, and the front end of the conductive ear seat 440 is rotatably connected to the third connecting hole 415.

[0035] Specifically, the angle-locked anchor unhooking mechanism works as follows: During manual anchor unhooking, the operator remotely pulls the pull rod 412 with a pull rope, causing the double-force unhooking plate 411 to rotate about the unhooking pin 420. The first connecting hole 413 of the double-force unhooking plate 411 moves upward, and the double-force unhooking plate 411 drives the connecting pin 331 through the first connecting hole 413. The connecting pin 331 pulls the lower end of the angle locking block 312 backward about the locking pin 311 through the connecting lug 332, causing the engaging opening 320 of the angle locking block 312 to gradually move away from the engaging angle 223 of the locking block 222. This releases the locking block 222 from the angle locking block 312, allowing the main hook 221 to swing forward about the main hook pin 230 under the action of gravity, allowing the anchor to separate from the main hook 221, thereby releasing the manually-operated anchor. The anchor then slides into the water under the action of gravity, anchoring the ship. In this way, the purpose of manual release is achieved, and the operator can complete the work of unlocking and releasing the anchor at a distance by pulling the rope, reducing the occurrence of the anchor chain slipping quickly and injuring the operator.

[0036] On the other hand, when the anchor is released by the driving rod 450, if manual unlocking is performed due to excessive friction between the locking block 222 and the angle locking block 312, resulting in insufficient manpower, the output end of the driving rod 450 is pushed out, and the output end of the driving rod 450 pushes the double-force unlocking plate 411 to rotate around the unlocking pin shaft 420 through the conductive ear seat 440, and the double-force unlocking plate 411 drives the lower end of the angle locking block 312 to swing backward around the locking pin shaft 311, releasing the lock of the locking block 222 by the angle locking block 312, so that the main hook body 221 swings forward around the main hook pin shaft 230 under the action of gravity, so that the anchor leaves the main hook body 221, thereby achieving the purpose of power release of the anchor.

[0037] When the main hook body 221 returns to its original position, after the pulling force of manpower and driving rod 450 is released, the double-force unlocking plate 411 returns to its original position under the torsion spring 430, and the double-force unlocking plate 411 pushes the lower end of the angle locking block 312 to swing forward and return to its original position through the connecting pin 331. At the same time, under the action of gravity, the upper end of the angle locking block 312 rotates around the locking pin shaft 311, and the lower end of the angle locking block 312 swings forward and downward under the action of gravity. The angle locking block 312 returns to its original position under the dual force of gravity and elastic force, and the main hook body 221 returns to its original position upward under the action of external force, and the locking block 222 pushes the angle locking block 312, so that the engaging angle 223 of the locking block 222 is automatically engaged in the engaging opening 320 at the lower end of the angle locking block 312, so that the engaging angle 223 and the engaging opening 320 form an angle self-locking The locking block 222 is in a state of swinging downward and forward around the main hook pin 230, and the locking block 222 and the main hook body 221 are an integrated structure. The locking block 222 has a tendency to move backward and upward, and the upper side of the engaging angle 223 of the locking block 222 faces the contact surface of the engaging opening 320 of the angle locking block 312, generating pressure. Since the angle between the upper side of the engaging angle 223 and the contact surface of the engaging opening 320 is smaller than the self-locking angle, the engaging opening 320 and the locking block 222 form an angle lock, so that the greater the force on the main hook body 221, the more stable the locking of the anchor is, and the occurrence of accidental anchoring is reduced. In addition, the return process of the main hook body 221 is simple, and the complicated operation of returning the main hook body 221 is reduced.
