Description

Technical Field

[0001] The invention relates to the field of shipbuilding, and in particular to a method for installing a deck light base. Background Art

[0002] During the ship construction process, when it is necessary to install a deck light on the deck, a hole is opened on the deck surface, the base of the deck light is welded and fixed on the deck, and then the deck light is installed on the base of the deck light.

[0003] A plurality of threaded holes are arranged on the base of the deck light, and corresponding mounting holes are arranged on the deck light. Bolts pass through the mounting holes and are threadedly matched with the threaded holes to realize mounting the deck light on the base.

[0004] However, during the welding process, the base is very easy to deform. Once deformed, the mounting hole may not fit the threaded hole. In this case, the base needs to be removed, corrected, and reinstalled. Although the deformation can be reduced to a certain extent if the deck light is installed on the base during welding, the deck light may be damaged during welding.

[0005] In addition, the deck lights are not installed immediately after the base is installed. The deck lights are usually installed just before the ship is delivered. Before the deck lights are installed, there are holes in the area where the base is located. Rainwater and cooling water used for pyrotechnic correction can easily enter the cabin or the next deck through the holes, causing damage to the equipment in the cabin or on the next deck. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a deck light base installation method. The present invention welds and installs the base through an anti-deformation device to avoid welding deformation of the base. After welding is completed, the anti-deformation device can also be used to seal the holes on the upper end of the base.

[0007] The technical objectives of the present invention are achieved through the following technical solutions:

[0008] A deck light base installation method, the method comprising the following steps:

[0009] S1. Mark out the base installation position on the deck and cut the installation position to form the base installation hole;

[0010] S2. Make a base anti-deformation device, install the base anti-deformation device on the base, then place the base at the mounting hole and fix the base to the edge of the mounting hole by spot welding;

[0011] S3. After ensuring that the upper surface of the base is flush with the plane on the deck, perform full welding between the base and the edge of the mounting hole;

[0012] S4. After the welding is cooled, grind the weld to check the vacuum tightness of the weld.

[0013] Furthermore, the method further comprises, after step S4, removing the anti-deformation device, installing a sealing gasket between the anti-deformation device and the base, and then reinstalling the anti-deformation device on the base.

[0014] Furthermore, in step S3, full welding is first performed on the upper plane of the deck, and then full welding is performed on the lower plane of the deck.

[0015] Furthermore, the base is annular, and a deck light mounting groove is provided in the middle of the base, and a plurality of threaded holes are provided at the bottom of the deck light mounting groove; the anti-deformation device includes a sealing plate that matches the deck light mounting groove, and the sealing plate is embedded in the deck light mounting groove, and mounting holes are provided on the sealing plate corresponding to the threaded holes, and bolts that match the threaded holes are passed through the mounting holes.

[0016] Furthermore, a bridge-type handle for taking the sealing plate is provided at the upper end of the sealing plate.

[0017] Furthermore, the handle is hingedly connected to the cover plate, and the cover plate is also provided with a door-shaped groove for storing the handle. The handle is rotated along the hinged position to be placed horizontally and then stored in the door-shaped groove.

[0018] Furthermore, after installation, the upper end surface of the base, the anti-deformation device and the upper plane of the deck are flush.

[0019] Furthermore, the sealing pad is a rubber pad or a sealing glue layer coated between the anti-deformation device and the base.

[0020] Compared with the prior art, the beneficial effect of the present invention is that, through the deck light base installation method of the present invention, on the one hand, the problem of the base being unable to meet the installation requirements of the deck light due to deformation caused by welding heat is avoided; on the other hand, after the base is welded, the anti-deformation device can also be used to seal the base to prevent water from flowing from the base into the cabin or the next deck.

[0025] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0026] A deck light base installation method, the method comprising the following steps:

[0027] S1. First, according to the hole layout of the deck light, use a sample punch to punch out the hole center on deck 1, then use a circle to draw the contour line according to the hole center, and use a cutter to cut along the contour line to form the base installation hole;

[0028] S2. Make a base anti-deformation device, such as Figure 1-3 As shown, the base 2 is annular, such as a circular ring, a square ring, a triangular ring, etc. In this embodiment, the base is in the shape of a circular ring, and a deck light mounting groove is provided in the middle of the base 2, and a plurality of threaded holes 4 are provided at the bottom of the deck light mounting groove 3; the anti-deformation device includes a sealing plate 9 matched with the deck light mounting groove 3, and the sealing plate 9 is matched and embedded in the deck light mounting groove 3, and a mounting hole 8 is provided on the sealing plate 9 corresponding to the threaded hole 4, and a bolt 10 matched with the threaded hole 4 is penetrated in the mounting hole 8, and the sealing plate 9 is connected to the base 2 as a whole through the bolt 10.

[0029] A bridge handle 6 for taking the closing plate is also provided at the upper end of the closing plate 9. The handle 6 is hingedly connected to the closing plate 9. A door-shaped groove 7 for storing the handle 6 is also provided on the closing plate 9. The handle 6 is rotated along the hinged position to be placed horizontally and then stored in the door-shaped groove 7. The handle 6 is lifted from the door-shaped groove 7 when in use, and is placed flat in the door-shaped groove 7 when not in use. This can prevent the handle from causing stumbling to people and can also facilitate the removal of the anti-deformation device.

[0030] Insert the sealing plate 9 into the deck light installation groove 3, then place the base 2 into the installation hole and fix it by spot welding the base to the edge of the installation hole;

[0031] S3. After ensuring that the upper surface of the base 2 is flush with the plane on the deck, the weld between the base and the edge of the mounting hole is fully welded; after the installation is completed, the upper end surface of the base 2, the anti-deformation device and the plane on the deck are flush, which further ensures the flatness of the deck surface and prevents people from tripping and falling and causing accidents.

[0032] When welding, firstly fully weld the weld 5 from the upper plane of the deck and remove the welding slag, and then fully weld the weld from the lower plane of the deck and remove the welding slag.

[0033] S4. After the welding is cooled, the weld 5 is polished to check the vacuum tightness of the weld.

[0034] Remove the anti-deformation device and install a sealing gasket (not shown in the figure) between the anti-deformation device and the base. The sealing gasket is a rubber gasket or a sealant layer coated between the anti-deformation device and the base. Then reinstall the anti-deformation device on the base. The setting of the sealing gasket can increase the waterproof performance of the sealing plate.

[0035] This embodiment is only a further explanation of the present invention, not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
