Technical Field

The invention relates to the technical field of ship construction, in particular to an integrated mounting method of a ship crane bracket and a highlight lamp mast.

Background

According to the requirements of OCIMF industry specifications on the transportation of goods of a liquid cargo ship, a liquid transportation operation area of the LNG ship is generally provided with a hose crane for hoisting tools, maintaining equipment and the like, and the hose crane is generally composed of two parts, namely a crane body and a bracket for storing a suspension arm. Meanwhile, according to the recommendation of arrangement of LNG ship cargo conveying areas in the SIGTTO industry standard, a strong light mast is required to be arranged on a deck of an operation area to illuminate night operation. The hose crane and the mast of the strong light lamp are indispensable devices and are all arranged near the gas collection platform. Meanwhile, the pipelines on the deck are dense, the crane bracket and the highlight lamp mast are large in size and should be separated from each other to avoid interference, but the crane bracket and the highlight lamp mast are functionally required to be close to each other, and a helicopter hovering area nearby limits the space, so that the area is always a difficult point in arrangement. The conventional method is to place the two parts at a certain distance, the highlight lamp mast cannot block the rotation of the crane, and the lamp mast is more or less blocked by the crane bracket to illuminate after being far away, so that the illumination effect is influenced to a certain extent. In addition, the occupied areas of the LNG carrier and the LNG carrier are large, the anti-wave cable is required to be pulled, the occupied areas are large, and great difficulty is brought to deck arrangement of crowded LNG carriers.

As a preferable technical scheme, in the third step, the straight ladder protection ring extends to the top of the operation platform, and a channel notch is formed in one side, facing the operation platform, of the straight ladder protection ring.

As described above, the integrated mounting method of the present invention has the following advantageous effects:

(1) the invention integrates the strong light mast on the crane bracket, effectively reduces the arrangement space required by the deck, saves the manufacturing cost of the strong light mast and the purchasing cost of binding the stable cable, and saves the manufacturing cost of the ship.

(2) According to the invention, after the high-light lamp masts are reduced, deep fusion welding during installation of each high-light lamp mast is reduced, welding seam inspection and spray painting of a mast body structure are reduced, and the construction period is shortened.

(3) The invention avoids the defects that the position of the strong light mast is too close to the crane bracket and the strong and stable cable of the light mast is difficult to install, thereby avoiding the problem of vibration of the strong light mast in the sailing process of a ship.

(4) The strong light mast is integrated on the crane bracket and is closer to a broadside operation area, so that the lighting effect of the strong light mast is enhanced.

Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and the present invention is not limited to the embodiments described herein.

Please refer to fig. 1 to 5. It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions of the present invention, so that the present invention has no technical significance. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

The embodiment provides a method for integrally installing a bracket of a ship crane and a mast of a strong light lamp, which comprises the following steps:

firstly, determining the installation position of a crane bracket on a deck; the installation position of the crane bracket can meet the requirements of storing the suspension arm and filling lubricating oil, and can also cover the requirement of strong light mast illumination. And the balance with a nearby pipeline and a cable model is also needed, and the avoidance of a channel is considered. Generally speaking, the crane carriage is 2m to 8m from the hook, which facilitates boom storage and lubricant filling. The strong light arranged on the crane bracket is 0-100 mm away from the edge of the deck, so that the lighting requirement can be met to the maximum extent. The arrangement interference needs to be noticed that the passage of the personnel normally riding the crane bracket can not be shielded by the parts such as pipes, cables and the like, and meanwhile, the position of the crane bracket can not block the walkway of the normal passage of the shipman on the deck.

Step two, manufacturing a crane bracket and a strong light lamp holder 6; firstly, a crane bracket column 1 and a suspension arm supporting seat 2 installed at the top of the crane bracket column 1 are manufactured, the crane bracket column 1 and the suspension arm supporting seat 2 are welded into a whole, then an operating platform 3 is manufactured, the operating platform 3 is arranged along the circumferential direction of the crane bracket column 1, the operating platform 3 is positioned at the upper part of the crane bracket column 1, and the highlight lamp holder 6 is installed at the outer side part of the operating platform 3; the size of the operation platform 3 is considered in arrangement, which can meet the space required by normal lubricating oil filling, and generally, the channel width of the operation platform 3 is more than 600 mm. The arrangement of the strong light lamp holder 6 needs to consider that as many lamps as possible are close to the edge of the deck and project to the operation area of the gas collecting platform, so that the lighting efficiency is highest, the height of the light arrangement platform needs to consider avoiding the dangerous area of the deck, the general deck surface is 2.4m upwards to be the dangerous area, and if a fan for ventilating the dangerous cabin exists nearby, the light arrangement platform needs to avoid the center of the fan by 4.5 m. In addition, the arrangement direction of the ascending vertical ladder 4 selected at the bottom of the crane bracket can not interfere with nearby pipes, connecting cables and the like, and can not block the main passing channel of the deck.

Step three, installing a reinforced toggle plate, riding a straight ladder 4 and a straight ladder guard ring 5, wherein the reinforced toggle plate is connected with the lower end surface of the operating platform 3 and the crane bracket column 1, the riding the straight ladder 4 is arranged along the height direction of the crane bracket column 1, the straight ladder guard ring 5 is arranged around the outside of the riding the straight ladder 4, the straight ladder guard ring 5 extends to the top of the operating platform 3, and a channel notch is formed in one side, facing the operating platform 3, of the straight ladder guard ring 5. Therefore, the traffic is ensured, and the safety of the personnel is well protected.

Fourthly, checking the strength; after the highlight lamp mast and the crane bracket are integrated, finite element analysis is carried out on the overall strength of the highlight lamp mast, and structural parameters of the bracket are optimized, such as the thickness of a 1 plate of the crane bracket column body, the diameter of the column body, the form of a reinforcing toggle plate and the like. The strength calculation analysis is carried out on the crane bracket and the whole ship structure according to the data such as the bracket maximum overturning moment, the turning moment, the vertical force and the like provided by a crane manufacturer, and the standard requirements of corresponding classification society are met.
