Description

Technical Field

[0001] This invention belongs to the field of cable bollard technology, and particularly relates to multifunctional cable bollards. Background Technology

[0002] Azimuth tugboats are characterized by their maneuverability, enabling them to move ships in any direction. They are primarily used for towing and pushing vessels and are widely employed in ports for various operations such as assisting large ships with berthing and unberthing, firefighting, and pilotage. Operating areas are generally divided into sheltered areas, coastal areas, near-shore areas, and open-sea areas. Common towing equipment for tugboats includes tow lines and tow hooks. Tow hooks are generally used for short-haul towing in sheltered and coastal areas, and the towline can be nylon. Tow lines are generally used for long-haul towing in near-shore and open-sea areas, and the towline is steel wire rope. For long-haul vessels, tow hooks can be used for short-haul towing operations to facilitate operation and save time.

[0003] Tugboats, designed for ease of operation, are relatively small with minimal superstructure. The space available for both the towline winch and tow hook at the stern is limited. Traditional bollards cannot simultaneously handle the guiding, mooring, and anchoring functions of both the winch and the tow hook, nor can they accommodate both top and bottom mooring deployment methods. Furthermore, the placement of bollards conflicts with the arrangement of vent pipes. While staggering or removing individual bollards is common, this necessitates readjusting the mooring angle, impacting usability. Removing vent pipes, typically located at the ends of compartments, reduces ventilation efficiency. Regardless of the solution, inherent flaws are likely to arise. Summary of the Invention

[0004] To address the shortcomings of traditional bollards, which cannot simultaneously handle the guiding, carrying, and attachment functions of towing winches and tow hooks, and to accommodate both top and bottom cable delivery methods, as well as the conflict between bollard and vent pipe arrangements, the present invention provides the following technical solution:

[0005] This invention relates to a multifunctional bollard, comprising a bollard body, a track plate, a tow hook, and a deck. The bollard body has two cable-carrying dividing holes. The top two sides of the bollard body are chamfered, and ram's horns are fixedly welded to the chamfers. Two eye plates are fixedly welded to one leg of the bollard body, and the eye plates are arranged vertically. A pin is fixedly inserted between the eye plates, and the tow hook is rotatably mounted on the pin.

[0006] The two lower openings of the cable-bearing bollard are fixedly connected to drainage pipes, and the two lower openings of the cable-bearing bollard are fixedly connected to ventilation pipes. The cable-bearing bollard has two longitudinal drainage grooves, and each drainage groove is equipped with a lifting component.

[0007] The lifting assembly includes a shaft frame, a drive motor, a limiting plate, a mounting bracket, and a lifting plate. The front side of the limiting plate has an integrally formed mounting base, which is slidably installed in the drainage groove. There is a pair of mounting brackets, both of which are fixedly installed on the mounting base. The top of each of the two mounting brackets is rotatably mounted with a mounting rod, and the mounting rod has a transverse sliding groove. The outer ends of each of the two mounting brackets are rotatably mounted with a support rod, and a sliding rod is rotatably mounted between the two support rods. The sliding rod is slidably installed in the sliding groove, and a locking rod is rotatably mounted in the sliding groove, with a torsion spring fixedly installed between the locking rod and the mounting rod.

[0008] As a preferred embodiment of the present invention, the cable-bearing pile body is "n"-shaped and made of seamless steel pipe.

[0009] As a preferred embodiment of the present invention, the bollard body is hollow and its two lower openings extend through the deck into the hull.

[0010] As a preferred embodiment of the present invention, the ram's horn is hollow and connected to the cable bollard body, and the ram's horn is provided with a plurality of dense ventilation holes.

[0011] As a preferred embodiment of the present invention, a transverse support steel pipe is fixedly welded to the bollard body, and a reinforcing plate is fixedly welded to both legs of the bollard body. An elbow plate is fixedly installed between both legs of the bollard body and the deck.

[0012] As a preferred embodiment of the present invention, the track plate is fixedly welded to the top of the deck, and two track wheels are fixedly installed at the bottom of the tow hook and the tow hook is slidably installed on the track plate through the track wheels. The track plate is an arc plate.

[0013] As a preferred embodiment of the present invention, the drainage pipe is a "U"-shaped tee pipe, the ventilation pipe is a "T"-shaped tee pipe, and a one-way valve is installed between the ventilation pipe and the two legs of the cable bollard body, with the one-way valve allowing unidirectional flow towards the cable bollard body.

[0014] As a preferred embodiment of the present invention, two shaft brackets are provided and fixedly installed on the inner wall of the support foot of the cable-stayed bollard body. A drive screw is rotatably installed between the two shaft brackets. A first bevel gear is fixedly installed at the bottom end of the drive screw. A drive motor is fixedly installed on the side end of the support foot of the cable-stayed bollard body, and a second bevel gear is fixedly installed at the output end of the drive motor. The second bevel gear meshes with the first bevel gear. The limiting disc is threadedly installed on the drive screw.

[0015] As a preferred embodiment of the present invention, the limiting disk is provided with a plurality of through-hole slots arranged in an equidistant circular array.

[0016] The beneficial effects achieved by this invention are:

[0017] The cable is divided by the cable splitting hole, and the cable is tied and fixed by the ram's horn. The added track wheel and the pin shaft make the tow hook rotate to meet different cable delivery requirements. The cable bollard body is "n" shaped to adapt to both cable delivery from the top and bottom of the cable towing machine.

[0018] Rotating the lifting plate 90° utilizes the elasticity of the torsion spring to return the locking rod to its original position and lock the sliding rod to prevent it from slipping back, thereby achieving the purpose of support and fixation. The drive motor drives the limit plate to lift and lower, thereby adjusting the height of the lifting plate. To store the lifting plate, simply pinch the locking rod with both hands, rotate the locking rod, and then rotate the lifting plate in the opposite direction to store it vertically.

[0019] The drainage trough directs water accumulated on the deck into the drainage pipe for discharge, and exhausts air from the ship's hold through the vent pipe. The added one-way valve prevents water from flowing back in. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example: Figure 1-6 As shown, the multi-functional bollard includes a bollard body 1, a track plate 2, a tow hook 3, and a deck 4. The bollard body 1 has two bollard dividing holes 101. The top two sides of the bollard body 1 are chamfered, and ram's horns 102 are fixedly welded to the chamfers. Two eye plates 105 are fixedly welded to one of the legs of the bollard body 1, and the eye plates 105 are arranged vertically. A pin 106 is fixedly inserted between the eye plates 105, and the tow hook 3 is rotatably installed on the pin 106. In use, the bollard is divided through the bollard dividing holes 101, and the bollard is tied and fixed through the ram's horn 102.

[0030] The two lower openings of the cable bollard body 1 are fixedly connected to the drainage pipes 108, and the two lower openings of the cable bollard body 1 are fixedly connected to the ventilation pipes 109. The cable bollard body 1 has two longitudinal drainage channels 110, and each of the two drainage channels 110 is equipped with a lifting component 5.

[0031] The lifting assembly 5 includes a shaft frame 501, a drive motor 502, a limiting plate 503, a mounting bracket 504, and a lifting plate 505. The limiting plate 503 has an integrally formed mounting base 510 on its front side, which is slidably mounted within a drainage groove 110. A pair of mounting brackets 504 are provided, both fixedly mounted on the mounting base 510. Mounting rods 511 are rotatably mounted on the top of each mounting bracket 504, and transverse sliding grooves 512 are formed on the mounting rods 511. Support rods 513 are rotatably mounted on the outer ends of each mounting bracket 504, and a sliding rod is rotatably mounted between the two support rods 513. The sliding rod is slidably mounted on the sliding plate. Inside the groove 512, a locking rod 514 is rotatably installed, and a torsion spring is fixedly installed between the locking rod 514 and the mounting rod 511. In use, after rotating the lifting plate 505 to 90°, the sliding rod slides backward in the groove 512. When the sliding rod passes the locking rod 514, it drives the locking rod 514 to rotate. After the lifting plate 505 is fixed, the elasticity of the torsion spring causes the locking rod 514 to return to its position and lock the sliding rod to prevent it from sliding back, thereby achieving the purpose of support and fixation. To store the lifting plate 505, simply hold the locking rod 514 with both hands, drive the locking rod 514 to rotate, and rotate the lifting plate 505 in the opposite direction to store it vertically.

[0032] The cable bollard body 1 is "n" shaped and made of seamless steel pipe. When in use, the seamless steel pipe can effectively improve the overall strength of the cable bollard body 1.

[0033] The bollard body 1 has a hollow design and two lower openings that extend through the deck 4 into the hull. This installation method can improve the stability of the bollard body 1 during use.

[0034] The ram's horn 102 is hollow and connected to the main body 1 of the cable bollard. Multiple dense ventilation holes are provided on the ram's horn 102. During use, exhaust and ventilation can be effectively carried out through the ventilation holes on the ram's horn 102.

[0035] A transverse support steel pipe 103 is fixedly welded to the bollard body 1. Reinforcing plates 104 are fixedly welded to both legs of the bollard body 1. Elbow plates 107 are fixedly installed between both legs of the bollard body 1 and the deck 4. In use, the added transverse support steel pipe 103, reinforcing plates 104 and elbow plates 107 can further improve the overall strength and installation firmness of the bollard body 1.

[0036] The track plate 2 is fixedly welded to the top of the deck 4. Two track wheels 301 are fixedly installed at the bottom of the tow hook 3, and the tow hook 3 is slidably installed on the track plate 2 through the track wheels 301. The track plate 2 is an arc plate. In use, the tow hook 3 can be rotated by the added track wheels 301 in conjunction with the pin 106 to meet different cable delivery requirements. The added track plate 2 can effectively prevent the track wheels 301 from wearing out and extend their service life.

[0037] The drain pipe 108 is a "U" shaped tee pipe, and the ventilation pipe 109 is a "T" shaped tee pipe. One-way valves are installed between the ventilation pipe 109 and the two legs of the bollard body 1. The one-way valves allow one-way flow towards the bollard body 1. When in use, the water accumulated on the deck 4 is guided into the drain pipe 108 through the drain trough 110 for discharge, and the air in the ship's hold is discharged through the exhaust pipe. The added one-way valves can prevent water backflow.

[0038] Two shaft brackets 501 are provided and fixedly installed on the inner wall of the support leg of the bollard body 1. A drive screw 506 is rotatably installed between the two shaft brackets 501. A first bevel gear 507 is fixedly installed at the bottom end of the drive screw 506. A drive motor 502 is fixedly installed on the side end of the support leg of the bollard body 1, and a second bevel gear 508 is fixedly installed at the output end of the drive motor 502. The second bevel gear 508 is meshed with the first bevel gear 507. A limit plate 503 is threadedly installed on the drive screw 506. In use, the drive motor 502 drives the second bevel gear 508 to rotate. The rotation of the second bevel gear 508 drives the drive screw 506 to rotate inside the shaft bracket 501 through the first bevel gear 507. The rotation of the drive screw 506 drives the limit plate 503 to rise and fall under the guidance of the drainage groove 110, so as to adjust the height of the lifting plate 505.

[0039] The limiting plate 503 has multiple through-hole slots 509 arranged in an equidistant circular array, through which air and water can circulate during use.

[0040] Specifically, in use, the cable is divided by the cable dividing hole 101, and the cable is bound and fixed by the ram's horn 102. The added track wheel 301, in conjunction with the pin 106, allows the tow hook 3 to rotate to meet different cable delivery requirements. The cable bollard body 1 is "n"-shaped to accommodate both top and bottom cable delivery methods of the cable towing machine. During the binding process, after rotating the lifting plate 505 to 90°, the slide rod slides backward in the slide groove 512. When the slide rod passes the locking rod 514, it drives the locking rod 514 to rotate. After the lifting plate 505 is fixed, the elasticity of the torsion spring causes the locking rod 514 to return to its original position and lock the slide rod to prevent it from sliding back, thereby achieving the purpose of support and fixation. The drive electric... The machine 502 drives the second bevel gear 508 to rotate. The rotation of the second bevel gear 508 drives the drive screw 506 to rotate within the shaft frame 501 through the first bevel gear 507. The rotation of the drive screw 506 drives the limit plate 503 to rise and fall under the guidance of the drainage groove 110, so as to adjust the height of the lifting plate 505. To store the lifting plate 505, simply hold the lever 514 with both hands, drive the lever 514 to rotate, and rotate the lifting plate 505 in the opposite direction to store it vertically. During use, the water accumulated on the deck 4 is guided into the drainage pipe 108 through the drainage groove 110 and discharged, and the air in the ship's hold is discharged through the exhaust pipe. At the same time, the added one-way valve can prevent water backflow.
