Description

Technical Field

[0001] The present application relates to the field of shipbuilding, and in particular to a method for calibrating the constant tension of a cruise ship mooring machine. Background Art

[0002] When a ship is moored, the tidal water level is constantly changing, which causes the mooring condition of the ship and the tension of the mooring rope to be in a constant process of change with the change of tide. In order to keep the ship in a safe and stable condition at all times, the tension of the mooring rope must be within the breaking tension range. The ship's mooring winch is usually equipped with an "automatic constant tension device", that is, when the tension of the ship's mooring rope is greater than or less than a certain set value, the mooring rope can automatically relax or tighten to ensure that the rope is not broken and the moored ship is safe. Therefore, before the ship is delivered, how to verify the setting value of the automatic constant tension device and the effect of the automatic constant tension device is particularly important for the safety of the mooring winch and even the safety of the ship.

[0003] At present, the verification method adopted is the "water bag method", but the preparation, filling, draining and later recovery of the water bags require a lot of manpower to cooperate. During the process of filling and draining water, special personnel must be arranged on the side and the bottom of the dock to monitor safety. The investment in manpower and material resources is considerable and the efficiency is low. Summary of the invention

[0004] In view of this, the purpose of the present application is to provide a method for calibrating the constant tension of a cruise ship mooring machine, so as to solve the problem of low efficiency and high overall cost of the existing "water bag method" for calibrating the constant tension of the cable.

[0005] According to the above purpose, the present invention provides a cruise ship mooring machine constant tension calibration method, which comprises the following steps:

[0006] S10: Arrange multiple mooring winches and bollards on the deck of the cruise ship;

[0007] S20: Using two different mooring machines to perform pulling to verify the constant tension of the cable of each mooring machine.

[0012] S240: Detect whether the mooring machine at the tested end automatically changes according to the set value;

[0013] S250: After the mooring machine at the tested end is stabilized, detecting whether the tension value on the dynamometer meets the set value.

[0016] The stern of the cruise ship is provided with four mooring winches to form a sixth mooring winch, a seventh mooring winch, an eighth mooring winch and a ninth mooring winch respectively.

[0017] Preferably, in the bow portion of the cruise ship, the first mooring machine is located at an end of the bow portion away from the stern portion;

[0018] The second mooring machine and the third mooring machine are located at one end of the bow portion close to the stern portion, and the second mooring machine and the third mooring machine are symmetrically arranged;

In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0044] like Figure 1 As shown, the cruise ship mooring machine constant tension calibration method includes the following steps:

[0045] S10: Arrange multiple mooring machines and cable guide bollards 10 on the deck of the cruise ship;

[0046] S20: Using two different mooring machines to perform pulling to verify the constant tension of the cable of each mooring machine (ie, whether it can be automatically adjusted).

[0047] Furthermore, in step S20, the following steps are specifically included:

[0048] S210: Determine two oppositely pulled mooring machines, where the two mooring machines are active ends and measured ends of each other;

[0049] S220: The cable is connected to the two mooring machines through the cable guide bollard 10, so that the two mooring machines are in a pulling state; and a tension meter is arranged on the cable;

[0050] S230: the mooring machine at the active end tightens or relaxes the cable to a value greater than the set value of different gears to simulate tidal changes (i.e., simulating that the tension of the cable is greater than or less than the set value under the influence of the tide);

[0051] S240: Detect whether the mooring machine at the tested end automatically changes according to the set value;

[0052] S250: After the mooring machine at the tested end is stabilized, detecting whether the tension value on the dynamometer meets the set value.

[0053] It should be noted that in the above step S210, it is necessary to ensure that each mooring winch is calibrated to ensure the stability and safety of the ship's mooring. In addition, the mooring winch located at the active end refers to the mooring winch that drives the cable to be tightened or loosened. It should be further noted that the mooring winches arranged on the cruise ship can be driven automatically by electricity, that is, they all have an automatic mooring mode, which usually has three gears, namely the first gear 50%-13 tons, the second gear 75%-19.5 tons and the third gear 100%-26 tons, wherein the third gear is the maximum load that can be tested, that is, the maximum tension on the cable. In addition, the set value of the cable tension is the tension corresponding to the above different gears, and this verification method can verify whether the mooring winch located at the tested end can adjust the cable to restore to the set value when the cable tension is greater than or less than the set value.

[0054] Specifically, in step S230, it is taken as an example that the mooring winch located at the active end tightens the cable to a value greater than the set value of the first gear; correspondingly, it should be detected whether the mooring winch located at the measured end can automatically adjust the slack of the cable (the adjustment time is usually 60 seconds); then, when the mooring winch located at the measured end is stable (i.e. after 60 seconds), detect whether the tension value on the tension gauge on the cable meets the set value. If the tension measured by the tension gauge is the set value, it means that the mooring winch under test has a regulating function that meets the delivery standards; if the tension measured by the tension gauge does not meet the set value, it means that the mooring winch under test does not meet the delivery standards and needs to be repaired or replaced.

[0055] Preferably, if Figure 2 As shown, in the above step S10, the plurality of mooring winches are respectively distributed at the bow and stern of the cruise ship. In this embodiment, the bow of the cruise ship is provided with five mooring winches, respectively forming a first mooring winch 1, a second mooring winch 2, a third mooring winch 3, a fourth mooring winch 4 and a fifth mooring winch 5; the stern of the cruise ship is provided with four mooring winches, respectively forming a sixth mooring winch 6, a seventh mooring winch 7, an eighth mooring winch 8 and a ninth mooring winch 9.

[0056] Furthermore, if Figure 2 As shown, in the bow of the cruise ship, the first mooring winch 1 is located at one end of the bow away from the stern; the second mooring winch 2 and the third mooring winch 3 are located at one end of the bow close to the stern, and the second mooring winch 2 and the third mooring winch 3 are symmetrically arranged (relative to the extension direction of the first mooring winch 1); along the extension direction of the cruise ship, the fourth mooring winch 4 and the fifth mooring winch 5 are located between the second mooring winch 2 and the first mooring winch 1, and the fourth mooring winch 4 and the fifth mooring winch 5 are symmetrically arranged. Furthermore, the first mooring winch 1, the second mooring winch 2 and the third mooring winch 3 are arranged in parallel; the fourth mooring winch 4 and the fifth mooring winch 5 form an angle.

[0057] like Figure 2 As shown, in the stern of the cruise ship, the sixth mooring winch 6 and the seventh mooring winch 7 are located at one end of the stern near the bow; the eighth mooring winch 8 is located on the side of the sixth mooring winch 6 away from the seventh mooring winch 7, and the ninth mooring winch 9 is located on the side of the seventh mooring winch 7 away from the sixth mooring winch 6. The sixth mooring winch 6 and the seventh mooring winch 7 are arranged in parallel; the sixth mooring winch 6 and the seventh mooring winch 7 are arranged symmetrically and form an angle.

[0058] By arranging multiple mooring winches as described above, the cruise ship can be moored at different docks more flexibly; by using mooring winches at different locations, the stability of the cruise ship during mooring can be guaranteed to the greatest extent.

[0059] Preferably, if Figures 3 to 6As shown, in step S210, the fourth mooring machine 4 and the fifth mooring machine 5 are pulled in opposite directions; the second mooring machine 2 and the third mooring machine 3 are pulled in opposite directions; the first mooring machine 1 and the fourth mooring machine 4 are pulled in opposite directions; the sixth mooring machine 6 and the seventh mooring machine 7 are pulled in opposite directions; the eighth mooring machine 8 and the ninth mooring machine 9 are pulled in opposite directions. It should be noted that the pulling method described above in this embodiment is the "extreme pulling path" of each mooring machine obtained through multiple verifications, that is, the mooring machine that has passed the verification using the pulling path described above must also pass the verification in other pulling paths. In addition, the number and arrangement positions of the cable guide piles 10 are in accordance with the method described in this embodiment. Figure 2 The disclosed arrangement will suffice.

[0060] According to the cruise ship mooring machine constant tension verification method described above, based on the characteristics that the cruise ship will have multiple mooring machines and cable guide piles 10, the interaction between the two mooring machines is used to verify whether each mooring machine can achieve its automatic adjustment effect. Compared with the currently used water bag method, the verification method used by the present invention uses the cruise ship's own equipment for verification, which is highly efficient and has a low overall cost.

[0061] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
