Description

Technical Field

[0001] This utility model relates to the field of mooring bollard technology, specifically to a mooring bollard that can quickly untie mooring lines. Background Technology

[0002] A bollard is a facility installed on the upper structure of a dock, mainly used for mooring ships and designed to prevent them from moving. Bollards are usually made of metal and are named for their columnar shape.

[0003] Existing mooring bollards are facilities installed on docks for mooring ships. In the existing technology, mooring bollards include a base installed in the ground foundation and a rope-winding post vertically fixed on the base. The rope is tied in the middle of the rope-winding post. Due to human or external factors, the rope may be tied very tightly. Sometimes, due to mistakes, the rope may be tied into a knot, which is inconvenient to untie and takes a long time.

[0004] According to CN207484407U, a mooring bollard for quick release of mooring lines includes a base fixedly installed in a ground foundation, and a vertical column fixedly connected to the base. The bollard also includes a horizontally insertable crossbar detachably mounted on the column, a locking bolt located on the central axis of the column and threadedly engaged with the column to clamp the crossbar, and a hemispherical end cap detachably mounted on the upper surface of the column. One end of the crossbar has a pull ring for assisting in disassembling the crossbar, and the upper end of the locking bolt has a handwheel fixedly connected to it and located inside the end cap. This invention enables quick release of mooring lines attached to the bollard.

[0005] The mooring bollard described above, which allows for quick untying of mooring lines, uses a horizontal bar inserted through the middle of the bollard. By utilizing the movable connection between the horizontal bar and the bollard, the horizontal bar can be pulled out, achieving the effect of quickly untying the mooring line. However, because the mooring line bears a large tension, even after the horizontal bar is pulled out, the mooring line remains wrapped around the bollard. This results in low efficiency and difficulty in operation. Therefore, we need to propose a mooring bollard that allows for quick untying of mooring lines. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a mooring bollard that can quickly untangle mooring lines. Its features include: a fixed box assembly 1, a rope winding assembly 2 installed inside the fixed box assembly 1, and an auxiliary assembly 3 installed inside the rope winding assembly 2. The fixed box assembly 1 includes a box body 11, with a limiting groove 14 inside the box body 11. An electric push rod 17 is fixedly installed at the bottom of the limiting groove 14. The rope winding assembly 2 includes a limiting plate 21 installed on the top of the electric push rod 17. The outer arc surface of the limiting plate 21 is movably installed inside the limiting groove 14. A rope winding post 22 is fixedly installed on the top of the limiting plate 21, and the outer arc surface of the rope winding post 22 is slidably connected to the top of the box body 11.

[0024] In use, by setting the fixed box assembly 1, the rope winding assembly 2 is placed inside the box body 11. By activating the electric push rod 17, the electric push rod 17 can drive the rope winding assembly 2 to move into the box body 11. When the rope winding column 22 is completely retracted into the box body 11, the cable on the rope winding column 22 is pushed away from the top of the rope winding column 22 by the obstruction of the box body 11, so as to achieve the effect of quickly untying the cable.

[0025] An inspection port 15 is provided on the left side wall of the enclosure 11. A door 16 is rotatably installed inside the inspection port 15, which facilitates the inspection of the interior of the enclosure 11.

[0026] A set of fixing plates 12 are fixedly installed on the bottom of both sides of the box 11. Two sets of mounting holes 13 are opened through the top of the two sets of fixing plates 12. The fixing plates 12 are installed in the designated position through the mounting holes 13 to achieve the effect of fixing the box 11.

[0027] The top of the rope post 22 is provided with an installation groove 23, and the inner side wall of the installation groove 23 is symmetrically provided with two sets of concave grooves 24. The installation groove 23 and the concave grooves 24 are designed to assist in the installation of the component 3.

[0028] A fixing rod 31 is fixedly installed at the bottom of the mounting slot 23. A sliding plate 32 is movably installed in the middle of the fixing rod 31, and one end of the fixing rod 31 extends through to the top of the sliding plate 32. A spring 33 is fixedly installed on the outer arc surface of the fixing rod 31 above the sliding plate 32. A post cap 25 is threaded to the top of the fixing rod 31. By utilizing the connection between the fixing rod 31 and the sliding plate 32, the sliding plate 32 can move up and down on the outer arc surface of the fixing rod 31. The spring 33 plays a limiting role for the sliding plate 32.

[0029] Two sets of first rotating seats 34 are fixedly installed on the outer side of the sliding plate 32. A set of push-pull rods 35 are rotatably installed on the inner side of the first rotating seats 34. A set of second rotating seats 36 is fixedly installed on the end of the push-pull rods 35 away from the sliding plate 32. A set of anti-detachment rods 37 is fixedly installed on the bottom of the second rotating seats 36. Utilizing the connection relationship between the sliding plate 32, the first rotating seats 34, the push-pull rods 35, the second rotating seats 36 and the anti-detachment rods 37, when the sliding plate 32 moves downward, it drives the anti-detachment rods 37 to rotate outward and maintain a fixed state under the action of the spring 33. Conversely, when the anti-detachment rods 37 rotate inward, it drives the sliding plate 32 to move upward. At this time, the spring 33 is in an energy storage state.

[0030] One end of each of the two sets of anti-detachment rods 37 is rotatably installed inside the concave groove 24. One end of each set of anti-detachment rods 37 can rotate to the outside of the rope winding post 22 through the concave groove 24. When the cable is fixed, the anti-detachment rods 37 are in a perpendicular rotation state with the rope winding post 22 to prevent the cable from falling off the top of the rope winding post 22. When the cable is released, the anti-detachment rods 37 rotate to the inside of the rope winding post 22 under the action of external force, so that the cable can be released from the top of the rope winding post 22.

[0031] In actual use, as shown in the figure, the electric push rod 17 has pushed the rope winding assembly 2 to the outside of the box 11, and the cable can be tied to the middle of the rope winding post 22. The anti-detachment plate 37 in the auxiliary assembly 3 is used to limit the cable and prevent the cable from falling off the top of the rope winding post 22, thereby achieving the effect of fixing the cable to the mooring post.

[0032] When it is necessary to untangle the cable, the electric push rod 17 is activated. The electric push rod 17 can drive the rope winding post 22 to move into the inside of the housing 11. When the rope winding post 22 is fully retracted into the inside of the housing 11, the cable moves upward towards the upper part of the rope winding post 22 under the obstruction of the housing 11. During the movement, the anti-detachment rod 37 rotates into the inside of the rope winding post 22 under the upward push of the cable. The cable continues to move upward until it detaches from the rope winding post 22, achieving the effect of quickly untangling the cable. Through the above device, the effect of quickly untangling the cable is achieved, and the operation is simple.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
