Description

Technical Field

[0001] This utility model relates to a navigation mark operation device, specifically a navigation mark wire rope threading device. Background Technology

[0002] During flood season, when conducting buoy berthing operations, the traditional wire rope threading work requires personnel to climb onto the buoy surface. However, during flood season, the weather and hydrological conditions are severe, and the navigation environment is complex. The turbulent currents cause the buoy to shake violently, posing a risk of personnel falling into the water. At the same time, the operation of the working vessel is also difficult and may collide with the buoy. All these factors cause the buoy berthing operation to take too long. The longer the time, the greater the risk, ultimately creating a vicious cycle. Therefore, it is urgent to improve the efficiency and safety of wire rope threading operations. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a navigation beacon wire rope threading device that is low-risk, highly efficient, and easy to use.

[0004] To solve the above-mentioned technical problems, the present invention provides a navigation beacon wire rope threading device, including a gripping rod. The front end of the gripping rod is fixedly provided with a locking seat having an inner locking groove with an inward opening and an outer locking groove with an outward opening. A movable rod is detachably locked into the locking seat. The movable rod is provided with a first pin for locking into the inner locking groove and a second pin for locking into the outer locking groove, and can rotate about the first pin or the second pin as a rotation axis. A rope hole for attaching a wire traction rope is provided on the side of the movable rod near the outer locking groove.

[0005] The movable rod includes two parallel connecting plates, and the first pin and the second pin are disposed between the two connecting plates and are located at positions corresponding to the inner slot and the outer slot.

[0006] A spacer is sleeved on the second pin, and the spacer is in elastic contact with the outer groove to provide damping to increase the force required for the movable rod to disengage from the outer groove.

[0007] The spacer is made of nylon.

[0008] A third pin is provided between the first pin and the second pin, and the third pin is used to limit the rotation angle of the movable rod through its contact with the locking seat.

[0009] An extension rod is hinged to the movable rod, and the rope hole is opened on the extension rod.

[0010] The advantages of this utility model are:

[0011] (1) Compared with the traditional method of guiding steel wire ropes in navigation marks, which requires manual operation on the surface of the float, this device has a longer grip bar, which allows users to complete the operation from a greater distance. At the same time, this device uses a narrower inner slot and a wider outer slot to cooperate with the spacer to install the movable rod in the clamping seat in a snap-fit ​​manner. Only two steps are required to complete the guiding operation, which is convenient and quick to use, greatly improving the efficiency of operation and reducing the risk of operation.

[0012] (2) The contact between pin three and the card seat restricts the rotation angle of the movable rod, so that when the movable rod rotates, it can leave a gap for the float hook to pass through, avoiding the problem that the rotation angle is too large and it is difficult to pass through the reaction force of the float hook to reset pin one, reducing the difficulty of operation when the device is retracted, thereby further improving the work efficiency.

[0013] (3) The two slots are designed to fall on a circle with the center of the end arc of each other as the center, so that the rotation of the moving rod is smoother. Attached Figure Description

[0018] The following detailed description of the navigation beacon wire rope threading device of this utility model, in conjunction with the accompanying drawings and specific embodiments, will be provided in further detail.

[0019] As shown in the figure, the navigation beacon wire rope threading device of this utility model includes a hand-held gripping rod 1. The front end of the gripping rod 1 is fixed with a U-shaped locking seat 4 with an inner locking groove 2 and an outer locking groove 3 by bolts. The two tips of the locking seat 4 have an inner locking groove 2 with an inward opening and an outer locking groove 3 with an outward opening, respectively. The ends of the two grooves are arc-shaped. The trajectory of the inner locking groove 2 is part of a circle with the center of the arc at the end of the outer locking groove 3 as the center. The trajectory of the outer locking groove 3 is part of a circle with the center of the arc at the end of the inner locking groove 2 as the center, so as to facilitate the rotation and insertion of the movable rod 5 to be installed later.

[0020] The movable rod 5 includes two parallel connecting plates 7, which are fixed together by pins 9 and 10 respectively positioned corresponding to the inner slot 2 and the outer slot 3. The movable rod 5 is detachably engaged with the locking seat 4 by the engagement of pin 9 with the inner slot 2 and pin 10 with the outer slot 3. A nylon spacer 8 is sleeved on pin 10, and the spacer 8 has elastic contact with the outer slot 3 to provide damping, thereby increasing the force required for the movable rod 5 to detach from the outer slot 3 and preventing the movable rod 5 from falling off the locking seat 4 due to gravity or other minor forces, while not affecting its rotation around pin 10. A third pin 11 is also provided on the movable rod 5 between pins 9 and 10, and the third pin 11 is used to limit the rotation angle of the movable rod 5 through its contact with the locking seat 4. An extension rod 10 is hinged to the edge of the movable rod 5 near the outer slot 3 via a pin. The end of the extension rod 10 has a rope hole 6 for attaching a steel wire traction rope.

[0021] During operation, bring the device close to the float hook and extend it forward until the movable rod 5 contacts it. At this time, the movable rod 5 rotates around the pivot pin 10, and the pivot pin 9 disengages from the inner groove 2. The rotation of the movable rod 5 stops when the pivot pin 11 contacts the locking seat 4. At this time, a gap appears between the movable rod 5 and the locking seat 4 for the float hook to pass through. After the float hook enters the internal space of the locking seat 4, move the device laterally to adjust the position of the float hook inside the locking seat 4. Then, retract the device towards the user. Because the spacer 8 sleeved on the pivot pin 10 provides damping, the retraction... When the movable rod 5 returns, it rotates in the opposite direction with the second pin 10 as the rotation axis instead of falling out of the outer slot 3. The first pin 9 can then return to the inner slot 2, and the float hook is fitted into the internal space of the locking seat 4. At this time, a larger force is used to continue to retract the device, pulling the second pin 10 with the spacer 8 out of the outer slot 3, so that the movable rod 5 rotates with the first pin 9 as the rotation axis. The steel wire traction rope tied in the rope hole 6 can then pass through the float hook together with the steel wire rope connected to its rear end, safely achieving the operation goal without the operator bearing any risk. At this time, the movable rod 5 can be easily removed from the locking seat 4.

[0022] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
