Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to an emergency anchoring device for a chain stopper. Background Art

[0002] Chain stoppers are essential equipment used on various engineering vessels, primarily responsible for bearing the anchor weight after lifting anchor at anchor. They are an essential component of a vessel's mooring system. When a vessel is anchored at sea, the chain stopper's blades restrict the movement of the anchor chain, bearing the majority of the load.

[0003] For example, in the prior art, application number CN202211049652.5 discloses a chain stopper comprising a base; a roller mounted on the base; a blade located on one side of the roller, one end of the blade rotatably connected to the base and the other end of the blade being a movable end; and a hydraulic lifting mechanism mounted on the base, wherein the movable end of the hydraulic lifting mechanism is connected to the movable end of the blade. During use, the anchor chain is placed on the roller. When the anchor chain needs to be locked, the hydraulic lifting mechanism descends, driving the movable end of the blade down. Once the blade is lowered into position, the blade can clamp the anchor chain between the roller and the blade. When the anchor chain needs to be released, the hydraulic lifting mechanism ascends, driving the movable end of the blade up, moving the blade away from the roller, thereby releasing the anchor chain and allowing it to slide on the roller. This chain stopper uses the hydraulic lifting mechanism to drive the blade up and down. Existing chain stoppers all use the blade to be fixed to the anchor chain. The above chain stopper uses a hydraulic mechanism to control the raising and lowering of the blade. Although it can easily control the fixation of the anchor chain, in an emergency, such as when the ship loses power, the hydraulic mechanism cannot be used, and the anchor chain is always in contact with the chain stopper blade. Due to the influence of the deadweight of the anchor claw and the deadweight of the anchor chain, the blade is difficult to disengage by manpower, affecting the anchoring work in an emergency.

[0004] With the increasing safety requirements for ship use, it is necessary to design a device that can manually drop anchor in an emergency when the ship loses power or electricity.

[0005] In view of the above, it is necessary to propose a chain stopper emergency anchoring device to solve the above problems. Utility Model Content

The internal thread is threadedly engaged with the external thread on the screw guide shaft. The upper end of the rotating part is an exposed end, and handle parts are respectively provided on both sides of the exposed end.

[0010] Furthermore, a hook is provided at the lower end of the screw guide shaft, and the hook is used to pull one end of the steel cable structure.

[0011] Furthermore, the release mechanism includes a base body, a release hook, and a release rod. The base body is fixedly arranged on one side of the vertical plate. The base body is hinged to the end of the release hook so that the release hook forms a clamp-shaped structure that can be opened or closed. The release rod is arranged at the open end of the clamp-shaped structure. One end of the release rod is hinged to the base body.

DETAILED DESCRIPTION

[0024] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] A chain stopper emergency anchoring device, such as Figure 1-5 As shown, it includes a base 1, a roller 2 is rotatably arranged in the base 1, the anchor chain is wound around the roller 2, and a knife 3 is provided on the base 1 to limit the movement of the anchor chain on the roller 2. Figure 1 As shown, the base 1 in the present device is basically the same as the existing structure. Two vertical plates 4 are parallelly provided in the vertical direction of the base 1. The roller 2 is rotatably connected and arranged between the two vertical plates 4. A cable-releasing channel 5 for retracting and releasing the anchor chain is formed between the two vertical plates 4. The roller 2 is rotatably arranged in the cable-releasing channel 5, and the anchor chain passes around the roller 2 for guided retraction and release operations. A knife 3 is provided in the front and upper part of the roller 2. One end of the knife 3 is hinged to the vertical plate 4 on one side. The knife 3 can be lifted or lowered by the hinge, so that it can cooperate with the roller 2 to clamp and fix the anchor chain. When the ship loses power or in some emergency situations, when the knife 3 cannot be opened automatically, it is considered very difficult to control its opening.

[0026] In order to solve the above problems, this embodiment provides a pulling mechanism 6 on the base 1, such as Figure 1 、 2 As shown, the pulling mechanism 6 is arranged in front of the gate knife 3, and a release mechanism 7 is provided on at least one side of the vertical plate 4. The pulling mechanism 6 and the release mechanism 7 are connected by a steel cable structure, and the steel cable structure is arranged through the chain hole of the anchor chain, as shown in FIG. Figure 5 As shown, the release mechanism 7 fixes one end of the steel cable structure, and the other end of the steel cable structure is driven by the pulling mechanism 6 to apply tension to the anchor chain, releasing the load on the chain stopper blade 3.

[0027] As an embodiment, the steel cable structure includes a steel wire rope 26, one end of the steel wire rope 26 forms a rope loop 27, and the other end forms a blocking block 28. The blocking block 28 in this embodiment forms a conical structure, and the tip of the cone points to the end of the rope loop 27, and the conical blocking block 28 is used to form a limit. One end of the steel wire rope 26 with the rope loop 27 provides tension to the steel wire rope 26 through the pulling mechanism 6. In actual use, the steel wire rope 26 is set to bypass the chain hole of the anchor chain, so when the steel wire rope 26 is pulled, the pulling force can lift the anchor chain slightly. At this time, all or part of the weight of the anchor chain release end is transferred to the steel wire rope 26, thereby reducing the pressure on the gate knife 3, and then the gate knife 3 can be opened manually more easily.

[0028] like Figure 2As shown, the pulling mechanism 6 can be used to pull up the anchor chain with a steel wire rope 26 with relatively little effort. Specifically, the pulling mechanism 6 includes a cross shaft portion 8, a screw guide shaft 9, and a driving handle 10. The cross shaft portion 8 includes a short shaft rod 11 rotatably connected to the vertical plates 4 on both sides. A sleeve portion 12 is connected between the two rotating shaft rods. The driving handle 10 is rotatably arranged in the sleeve portion 12. The screw guide shaft 9 is arranged through the sleeve portion 12, so that the short shaft rod 11 and the screw guide shaft 9 are arranged in a cross shape; the screw guide shaft 9 is made to swing within a certain angle range in the cable-releasing channel 5 with the short shaft rod 11 as the axis. Figure 3 As shown, when the pulling mechanism 6 rotates around the short shaft 11, Figure 3 As shown, it can be understood that according to the different positions of the anchor chain pulled by the wire rope 26 and gradually tightened, the screw guide shaft 9 is kept in the same straight line with the wire rope 26 under the action of tension. This swing range can enable the screw guide shaft 9 to maintain maximum efficiency in pulling the wire rope 26, which can further save effort.

[0029] Specifically, such as Figure 2 As shown, the driving handle 10 includes a rotating portion 13 and a handle portion 14. The outer ring of the rotating portion 13 is rotatably arranged in the sleeve portion 12. An annular groove is provided on the inner wall of the sleeve portion 12. A convex ring 36 is provided on the outer ring of the rotating portion 13 so that the convex ring is rotatably arranged in the annular groove. Pressure bearings are provided on the upper and lower sides of the convex ring to limit the height position of the rotating portion 13 relative to the sleeve portion 12. At the same time, the rotating portion 13 can be freely rotated in the sleeve portion 12. It can be understood that the rotation of the rotating portion 13 is driven by the handle portion 14. The upper end of the rotating portion 13 is an exposed end 16, and handles are provided on both sides of the exposed end 16. Part 14; Multiple handles 14 can be set around the exposed end 16, so as to facilitate the manual driving of the rotating part 13 to rotate. When the rotating part 13 rotates, it is used to drive the screw guide shaft 9 to move axially; the inner ring of the rotating part 13 is provided with an internal thread 15, and the internal thread 15 is threadedly engaged with the external thread on the screw guide shaft 9. It can be understood that the screw guide shaft 9 is restricted from circumferential rotation relative to the sleeve part 12. This can be achieved by setting a card slot. The screw guide shaft 9 is controlled to move up and down in the sleeve part 12 only by the rotation of the rotating part 13. When the screw guide shaft 9 moves upward, it pulls the wire rope 26, and vice versa. The lower end of the screw guide shaft 9 is provided with a hook 17, and the hook 17 is used to pull one end of the steel cable structure. Specifically, the rope loop 27 at the end of the steel cable structure is put on the hook 17 for pulling.

[0030] According to the above principle, when the steel cable structure is tensioned, the anchor chain can be pulled, and the pressure of the gate can be released, and then the gate can be operated; after completing the above operations, the steel cable structure needs to be released, and then the anchor chain can be released. Specifically, in this embodiment, the release mechanism 7 is used to loosen one end of the steel cable structure to set the blocking block 28. The release mechanism 7 includes a base body 18, a release hook 19, and a release rod 20. The base body 18 is fixedly set on one side of the vertical plate 4. The base body 18 is hinged to the end of the release hook 19 so that the release hook 19 forms a clamp-shaped structure that can be opened or closed. The release rod 20 is set at the open end of the clamp-shaped structure. The blocking block 28 cooperates with the release mechanism 7. Specifically, the blocking block 28 is a conical structure, and a conical hole that cooperates with the blocking block 28 is provided in the clamp-shaped structure, such as Figure 2 、 4 As shown, the base body 18 and the release hook 19 are respectively provided with a semi-conical hole 29. When the clamp structure composed of the base body 18 and the release hook 19 is closed, the two semi-conical holes 29 form a conical hole, and a through hole 30 corresponding to the conical hole is provided on the vertical plate 4 to facilitate the passage of the wire rope 26. Before installation, open the clamp structure as shown in FIG. Figure 4 As shown, the blocking block 28 is passed through the through hole 30 and the semi-conical hole 29 from the inner side of the vertical plate 4, and then the release hook 19 is closed. After closing, the release rod 20 is clamped on the release hook 19, as shown in FIG. Figure 3 As shown, specifically, one end of the release rod 20 is hinged on the base body 18, and the release rod 20 is provided with a retaining structure 21 for controlling the release hook 19 to close on the base body 18, and the retaining structure 21 includes two trapezoidal limit blocks that can bite each other, and a first limit block 31 is fixedly set at the end of the release hook 19, and a second limit block 32 is set on the release rod 20. The inclined surfaces of the two limit blocks fit together to form a bite shape, and the setting direction of the inclined surface is configured to be in a state that becomes tighter and tighter under the guidance of the inclined surface in a natural state; when the clamp structure is closed, the first limit block 31 of the release rod 20 is clamped on the second limit block 32, so when the wire rope 26 is tightened, the blocking block 28 can be clamped in the tapered hole to form a limit.

[0031] The other end of the release lever 20 is a pulling end 22, which drives the release lever 20 to rotate and release the limit on the release hook 19. The pulling end 22 is set at the upper end of the release lever 20, and is provided with a hole. It can be remotely controlled by pulling the wire to control the release lever 20 to rotate, thereby releasing the limit on the release hook 19, forming a Figure 4 As shown in the figure, the stopper 28 is not restricted and can be released from the through hole 30. The stopper 28 is smaller than the chain hole so that the stopper 28 can pass through the chain hole. Therefore, the operation of releasing the anchor chain can be completed.

[0032] In order to ensure that the release hook 19 can be quickly opened and supported after the release rod 20 is pulled up to prevent it from falling back again, the device is provided with an elastic member on the upper end surface of the base body 18, and a countersunk hole 35 is provided on the upper end surface of the base body 18. A spring 33 is provided in the countersunk hole 35, and a push rod 34 is provided on the upper side of the spring 33. The push rod 34 will be compressed when the release hook 19 is closed. When the release hook 19 is released, the release hook 19 can be quickly bounced open under the action of the spring 33.

[0033] Furthermore, the release mechanism 7 is also provided with a safety pin 23. In order to avoid misoperation, the safety pin 23 needs to be inserted throughout the gate opening process to prevent the release hook 19 from popping open. When the gate operation is completed and the surrounding personnel have maintained a safe distance, the safety pin 23 is pulled out and then the release lever 20 is pulled. Specifically, Figure 2-4 As shown, the release lever 20 and the release hook 19 have an overlapping portion 24. A pin hole 25 is provided in the overlapping portion 24 for inserting a safety pin 23. The safety pin 23 is inserted into the pin hole 25, thereby integrating the release hook 19 with the release lever 20. The safety pin 23 can be sequentially inserted into the pin holes 25 of the release lever 20 and the release hook 19 to connect them together. When removed, the release hook 19 can be opened normally.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
