Description

Technical Field

[0001] The utility model relates to ship and ocean engineering technologies, and more specifically, to a lifting fairlead. Background Art

[0002] The fairlead on a ship is used to guide or fix a cable. The fairlead / cable roller on an existing ship is directly welded and fixed on the deck. However, when the ship rises and falls on the sea surface with the tide or its own loading draft changes, there will be a height change of the ship relative to the mooring point at the dock. Although the length of the cable can be adjusted at this time, due to the change in the height difference in the vertical plane, the stress angle of the cable may change greatly, and certain risks may be brought in some extreme cases. Summary of the Utility Model

[0003] Aiming at the defects existing in the prior art, the purpose of the utility model is to provide a lifting fairlead, which is a mechanically lifted and height-adjustable fairlead, enabling the fairlead to have a lifting function.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A lifting fairlead includes a mechanical lifting base, a lifting component, a fairlead body, and a dock position monitoring component;

[0006] There are a pair of the mechanical lifting bases, symmetrically arranged at the side position of the ship;

[0007] The fairlead body is arranged between the pair of mechanical lifting bases through the lifting component, and the lifting component is used to realize the up / down movement of the fairlead body relative to the mechanical lifting base;

[0008] The dock position monitoring component is arranged at the side position of the ship, used to monitor the height difference between the dock and the deck surface of the ship, obtain position information and provide it to the lifting component to control the up / down movement of the fairlead body.

[0009] Preferably, the mechanical lifting bases are both vertically arranged box structures;

[0010] Racks are arranged on the opposite inner surfaces of the box structures.

[0011] Preferably, the lifting component includes a gear and a motor;

[0012] The gear is arranged on the output side of the motor;

[0013] The gear meshes with the rack.

[0014] Preferably, the wharf position monitoring component includes a vision sensor and an analysis and processing unit;

[0015] The vision sensor is used to obtain the position information of the ship and transmit it to the analysis and processing unit;

[0016] The analysis and processing unit is used to control the start and stop of the motor.

[0017] The lifting fairlead provided by the present utility model has a lifting function, which can reduce the risk of the change in the force of the mooring cable caused by the relative height change between the ship and the fixed mooring point of the wharf. If used in combination with the automatic detection of the wharf position and the automatic tensioning function of the cable, it can realize the automatic adjustment of the length and tension of the mooring cable of the ship, reduce the operation of relevant personnel, and be safer at the same time.

[0022] In order to better understand the above technical solutions of the present utility model, the technical solutions of the present utility model will be further described below with reference to the drawings and embodiments.

[0023] Combined with Figures 1 to 4 As shown, a lifting fairlead provided by the present utility model includes a mechanical lifting base, a lifting component, a fairlead body 1, and a wharf position monitoring component.

[0024] There are a pair of mechanical lifting bases, which are symmetrically installed at the side position of the ship 100.

[0025] The fairlead body 1 is installed between a pair of mechanical lifting bases through a lifting component, and the lifting component is used to realize the up / down movement of the fairlead body 1 relative to the mechanical lifting base.

[0026] The wharf position monitoring component is also installed at the side position of the ship 100, and is used to monitor the height difference between the wharf 200 and the deck surface of the ship 100, and obtain the position information to provide to the lifting component to realize the control of the up / down movement of the fairlead body 1.

[0027] The mechanical lifting base is a box structure 2 arranged vertically to ensure that the fairlead body 1 can move up and down and bear all the loads on the fairlead body 1.

[0028] Racks 3 are installed on the opposite inner surfaces of the two box structures 2.

[0029] The lifting assembly includes a gear 4 and a motor. The gear 4 is installed on the output side of the motor. The gear 4 meshes with the rack 3. By driving the meshing transmission of the gear 4 and the rack 3 by the motor, the lifting movement of the fairlead body 1 along the mechanical lifting base is realized.

[0030] The dock position monitoring assembly includes a vision sensor 5 and an analysis and processing unit. The vision sensor 5 is used to obtain the position information of the ship 100, including the heave motion and horizontal motion of the ship 100, and transmit this information to the analysis and processing unit. The analysis and processing unit automatically calculates the optimal height position of the fairlead body 1 based on the position data of the dock 200, the motion data of the ship 100, the height data of the fairlead body 1, etc., according to geometric principles and load characteristics, and thus drives the motor to start and adjust the height of the fairlead body 1.

[0031] The lifting fairlead of the present utility model can also be used in cooperation with a constant tension winch 300 to achieve unmanned automatic adjustment.
