Description

Technical Field

[0001] The present invention relates to the technical field of ship mooring, and particularly relates to a ship mooring device and method. Background Art

[0002] A ship is a transportation tool that uses the buoyancy of water and sails on or in the water through power or manpower. Its main functions include: transportation: goods (container ships, oil tankers), personnel (passenger ships, cruise ships); operations: offshore engineering (dredgers, drilling platforms), fisheries (fishing boats), rescue (lifeboats); military: warships, submarines, aircraft carriers, etc. for national defense purposes; scientific research: ocean research ships, polar research ships.

[0003] Ship mooring refers to the process of fixing a ship to a dock, anchorage or other structure through equipment such as cables, anchor chains, and buoys to ensure its stability and safety during berthing. The existing cable-type ship mooring usually involves manually tying the cable to a pile or pier on the shore. However, compared with the human body, the hull is generally larger. Due to the influence of water flow during mooring, the pulling force of the hull is very large, making manual mooring more difficult and less efficient. Summary of the Invention

[0004] The purpose of the present invention is to provide a ship mooring device and method to solve the problems of difficult and inefficient manual cable mooring.

[0005] To achieve the above purpose, the present invention provides a ship mooring device, which includes a mooring frame with a rotating function. An elevating drive structure is arranged at the top of the mooring frame. The elevating drive structure is connected to a cable pulling and tensioning assembly with an elevating function. The side of the cable pulling and tensioning assembly is connected to the mooring frame through an elevating guiding structure. A rotating fixing assembly for mooring cables is arranged below the cable pulling and tensioning assembly.

[0006] Preferably, the mooring frame includes a top frame and a fixing frame. The bottom end of the fixing frame is rotatably connected to a base. A rotating motor is arranged inside the base. The output shaft of the rotating motor is connected to the bottom end of the fixing frame. The top end of the fixing frame is connected to one end of the top frame. The elevating drive structure is arranged at the other end of the top frame.

[0007] Preferably, the elevating drive structure includes a plurality of rotating rollers rotatably arranged on the top frame. One end of each rotating roller is connected to a drive motor, and a steel wire rope is wound around the rotating rollers.

[0008] Preferably, the cable pulling and tensioning assembly includes an elevating structure and a cable clamping structure. The elevating structure includes a plurality of guiding tubes. A through hole is arranged on the top frame. The end of the steel wire rope away from the rotating roller passes through the through hole and the guiding tubes and is connected to an elevating block. One side of the elevating block is connected to a fixing seat.

[0009] Preferably, the guiding tube is provided with a strip-shaped opening for the lifting of the lifting block, and the lifting block is arranged in the strip-shaped opening and is slidably connected with the strip-shaped opening.

[0010] Preferably, the cable clamping structure includes two clamping blocks moving towards each other arranged at the bottom end of the fixed seat. There is an opening on the fixed seat, and a first hydraulic cylinder is arranged at the top end of the fixed seat. The top end of the clamping block passes through the opening and is connected to the hydraulic rod of the first hydraulic cylinder.

[0011] Preferably, the lifting guiding structure includes a plurality of fixing plates. The guiding tube is fixed to one side of the fixing plate, and the other side of the fixing plate is connected to the fixing frame through a connecting plate.

[0012] Preferably, the rotating fixing assembly includes a rotating clamping structure and an elastic blocking structure. The rotating clamping structure includes a rotating platform. A groove for the rotating winding of the cable is arranged on the side surface of the rotating platform. The rotating platform is rotatably arranged on the base. A rotating motor is arranged in the base, and the output shaft of the rotating motor is connected to the bottom end of the rotating platform; Hydraulic cylinders II are symmetrically arranged on the rotating platform. The hydraulic rods of the hydraulic cylinders II are connected to the clamping plates. A slider is arranged at the bottom end of the clamping plate. A chute adapted to the slider is arranged on the rotating platform. The slider is arranged in the chute and is slidably connected with the chute.

[0013] Preferably, the elastic blocking structure is arranged directly below the cable clamping structure. The elastic blocking structure includes symmetrically arranged blocking plates. The middle of the blocking plate is rotatably connected to the clamping plate. One side of the lower end of the blocking plate is connected to the clamping plate through a spring, and a clamping block is arranged on the other side of the lower end of the blocking plate.

[0014] The present invention also provides a mooring method for a ship mooring device, including the following steps: Step 1, after the ship stops at the shore, one end of the cable is placed between the two clamping blocks, and the first hydraulic cylinder drives the clamping blocks to clamp the cable; Step 2, the rotating motor drives the fixing frame to rotate, and then drives the top frame to rotate, driving the clamped cable to move above the rotating fixing assembly; Step 3, the driving motor drives the rotating roller to rotate, so that the steel wire rope moves downward along the conduit, and then drives the lifting block to move downward. The downward movement of the lifting block drives the fixed seat to move downward, and then drives the clamped cable to move downward; Step 4, after the cable moves downward to the bottom position of the guiding tube, the clamping blocks loosen the cable, and the cable falls between the clamping blocks of the two blocking plates. The second hydraulic cylinder drives the clamping plate to move, and then drives the blocking plate to move to clamp the cable.

[0015] Step 5, the rotating motor drives the rotating platform to rotate, and winds the cable in the groove of the rotating platform to complete the mooring of the ship.

[0016] Therefore, the present invention adopts the above-mentioned ship mooring device and method, and has the following beneficial effects: The present invention automatically clamps the cable by means of clamping blocks with a function of moving towards each other, and automatically lowers the cable in cooperation with a cable with a lifting function. The cable moves up and down in the guide pipe to reduce the swaying of the cable; the cable is lowered between the clamping plates, and the clamping plates drive the blocking plates to automatically clamp the cable. The lifting platform rotates to wind and fix the cable, automatically completing the cable fixing, reducing manual operation, being more convenient and fast, solving the problem of difficult mooring caused by the large size and easy movement of the hull during manual mooring, and improving the mooring efficiency at the same time.
