Description

Technical Field

[0001] This application relates to the field of shipbuilding technology, and in particular to a method for permanently fixing a boarding tower. Background Technology

[0002] In horizontal slipway shipbuilding, each time a ship is loaded onto the deck, it needs to be launched from the boarding tower. However, each time a half-ship is moved or a whole ship is launched, cranes and personnel are needed to dismantle the boarding tower. Furthermore, when the sections are assembled into a half-ship or a whole ship, cranes and personnel are needed to install and fix the boarding tower. This repeated assembly and disassembly work results in a lot of wasted costs. Summary of the Invention

[0003] Based on the characteristics of horizontal slipways, ship features, and tooling ladders, this invention provides a method for permanently fixing a boarding tower, saving crane resources and reducing construction costs.

[0007] The boarding tower is hoisted and then cured.

[0008] In some embodiments, determining the installation position of the boarding tower based on the tandem arrangement of ships on the horizontal slipway includes:

[0009] The horizontal slipway loading line is constructed in a series of one full ship and one half ship, with the stern half ship position selected at the full ship position.

[0010] Then, based on the type of boarding tower and the distance between the boarding tower and the outer plating of the hull, to prevent interference between the boarding tower and the movement of half or the whole ship, the installation position is selected.

[0014] A circular tube is added inside the kinetic energy channel corresponding to the suspended position of the tower leg. The circular tube is arranged radially perpendicular to the bottom surface of the kinetic energy channel to provide reinforced support.

[0015] In some embodiments, a pad is added to the bottom of the circular tube to increase the force-bearing area of ​​the circular tube.

[0016] In some embodiments, a diagonal bracing tube is provided between the side surface of the circular tube and the bottom surface of the kinetic energy channel for diagonally supporting the circular tube.

[0017] In some embodiments, the number of the diagonal bracing tubes is two or more.

[0018] In some embodiments, the corresponding laying of the base plate includes: the base plate being fixedly laid across the ground on both sides of the kinetic channel, covering the area corresponding to the projection of the boarding tower toward the ground, and the top of the circular tube abutting against the bottom surface of the base plate.

[0031] In order to gain a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

[0032] In the embodiments described in this application, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can be an electrical connection, or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0033] This invention provides a method for permanently fixing a boarding tower, such as... Figure 1 As shown, the method includes the following steps:

[0034] Step 101: Determine the installation location of the boarding tower based on the tandem arrangement of ships on the horizontal slipway.

[0035] In some embodiments, determining the installation location of the boarding tower according to the tandem arrangement of ships on the horizontal slipway includes:

[0036] like Figure 2 As shown, the horizontal slipway loading line is constructed in series with one full ship 30 and one half ship 31, and the stern half ship position is selected at the position of the full ship 30.

[0037] Then, based on the form of the boarding tower 10 and the distance between the boarding tower 10 and the outer hull plate of the whole ship 30, to prevent interference between the movement of the half ship 31 and the whole ship 30 and the boarding tower 10, the installation position is selected.

[0038] The horizontal slipway is constructed using a series of one full ship and one half ship, so a full ship is placed on the side closer to the harbor basin and a half ship is placed on the other side.

[0039] Normally, the stern half of the ship is loaded first during ship construction. After the stern half is loaded, it will be moved to the position of the whole ship for loading.

[0040] Since the stern half-boat will be continuously hoisted, which may interfere with the crane's wire rope, it is not a good location. Therefore, the full-boat location is selected. The first half-boat will also be hoisted separately in the full-boat location. Finally, the stern half-boat location in the full-boat location is selected as the best option.

[0041] Then, based on the type of boarding tower and the calculated distance between the boarding tower and the hull plating, to prevent interference with the boarding tower during half-ship or full-ship movement, the final position is selected.

[0042] Step 102: Determine the suspended position of the tower legs of the boarding tower according to the installation location, strengthen the kinetic energy channel corresponding to the suspended position of the tower legs, and lay the corresponding base plate.

[0043] like Figure 3 As shown, because both sides of the vessel 30 on the boarding line are covered with underground kinetic energy channels 20, the ground on both sides is suspended. The boarding tower 10 itself is heavy and will be even heavier during use, so the suspended ground cannot currently bear its weight.

[0044] In some embodiments, determining the suspended position of the tower legs of the boarding tower based on the installation location includes:

[0045] Draw lines at the installation location to simulate the position of the tower legs of the boarding tower 10, and then determine the position of the tower legs in the air.

[0046] Draw lines in advance at the location where the boarding tower will be placed, and simulate the position of the boarding tower legs in advance for accurate positioning.

[0047] In some embodiments, such as Figure 4 and Figure 5 As shown, the kinetic energy channel corresponding to the suspended position of the tower leg is strengthened, including:

[0048] A circular tube 22 is added inside the kinetic energy channel 20 corresponding to the suspended position of the tower leg 11. The circular tube 22 is set radially perpendicular to the bottom surface of the kinetic energy channel 20 to provide reinforced support.

[0049] In some embodiments, a circular tube is pre-installed in the kinetic energy channel at the suspended position of the boarding tower leg. The diameter of the circular tube is 319*12-1000mm.

[0050] In some embodiments, such as Figure 4 and Figure 5 As shown, a pad 24 is added to the bottom of the circular tube 22 to increase the force-bearing area of ​​the circular tube 22.

[0051] In some embodiments, a diagonal bracing tube 23 is provided between the side of the circular tube 22 and the bottom surface of the kinetic energy channel 20 for diagonally supporting the circular tube 22.

[0052] In some embodiments, the number of diagonal bracing tubes 23 is two or more.

[0053] The diagonal bracing tubes are 219*10-800mm in diameter. Three diagonal bracing tubes are installed on three sides of the tube to form a triangular frame.

[0054] In some embodiments, such as Figures 4 to 6 As shown, the corresponding base plate 21 is laid, including: the base plate 21 is fixedly laid on the ground 19 on both sides of the kinetic energy channel 20, covering the corresponding area projected from the boarding tower 10 to the ground, and the top of the circular tube 22 abuts against the bottom surface of the base plate 21.

[0055] Here, the base plate 21 may include a steel plate. In some embodiments, after the kinetic energy channel is reinforced, a steel plate with a thickness of t = 25mm and a size of 7 meters * 4.5 meters is laid on the ground, and the ground under the steel plate is cleaned and leveled. The steel plate is fixed to the ground with L-bolts, and all four corners need to be fixed. Four L-bolts are fixed to each corner.

[0056] Step 103: Hoist the boarding tower 10 and then solidify it.

[0057] In some embodiments, such as Figures 3 to 6 As shown, the hoisting and curing of the boarding tower 10 includes:

[0058] The tower legs 11 of the boarding tower 10 are welded and fixed to the base plate 21.

[0059] An I-beam fixture 25 is placed across the kinetic energy channel 20 on the base plate 21 and connected to the two tower legs 11 of the boarding tower 10 to improve the support of the base plate 21 for the boarding tower 10.

[0060] After the base surface has hardened, the boarding tower is hoisted to the designated position on the ground steel plate using a crane. The tower legs are then welded to the base plate, with a weld length of at least 15mm. After welding, an I-beam fixture is placed across the kinetic energy channel on the base plate and connected to the tower legs, ensuring sufficient lateral force on the base plate. The I-beam fixture is then welded to the base plate and tower legs, with a weld length of at least 15mm. The upper end of the boarding tower is secured to the main deck railing using clamps. A mesh panel is installed between the boarding tower and the main deck ladder, connecting to the railing to form a complete structure.

[0061] The above embodiments of the present invention provide a method for permanently fixing a boarding tower, which reduces the repeated disassembly and assembly of the boarding tower, reduces the number of times the crane is used for hoisting, saves crane resources, and reduces construction costs.

[0062] The technical solutions described in the embodiments of this application can be combined arbitrarily without conflict.

[0063] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
