[0054] Reference Figure 1 and Figure 2 As shown, this embodiment provides a method for manufacturing and installing a radar mast.

[0055] Specifically, the radar mast includes a support body 100, a fixing accessory 200, and a signaling device 300.

[0056] Specifically, the manufacturing and installation method of the radar mast includes the following steps:

[0057] S100, weld the bracket body 100, and fix the fixing accessory 200 to the bracket body 100.

[0058] S200, The main body of the support frame 100 is lifted from the ship onto the ship and fixedly installed.

[0059] S300: Connect the signal device 300 to the fixing accessory 200 to achieve the positioning and installation of the signal device 300 relative to the bracket body 100.

[0060] The main body 100 of the support structure can be lifted from the ship onto the ship using a crane (not shown).

[0061] In this embodiment, firstly, the welding of the support body 100 and its connection with the fixing accessories 200 are completed; then, the support body 100 is hoisted from the ship onto the ship and fixedly installed, thus avoiding the need to set up scaffolding on the ship, effectively reducing the workload of workers, ensuring worker safety, and avoiding the transportation of materials and tools. Furthermore, the final installation of the signal device 300 reduces the risk of impact to the signal device 300 and provides a certain degree of protection for it.

[0062] In one feasible implementation, the manufacturing of the support body 100 and the fixing accessories 200 can be outsourced, requiring only a bill of materials and related drawings. The bill of materials and related drawings can be packaged together for easy acceptance.

[0063] In this embodiment, reference is made to Figure 2 As shown, the support body 100 includes a plurality of platform frames 110 arranged sequentially from top to bottom. Step S100 includes the following steps:

[0064] S110, multiple platform frames 110 are manufactured separately.

[0065] S120. Install the fixing accessory 200 onto the corresponding platform frame 110.

[0066] S130, assembling multiple platform frames 110.

[0067] In this embodiment, multiple platform frames 110 are manufactured separately and then assembled and welded, i.e., modular separate operation, which can effectively improve the efficiency of welding the main body 100 of the support frame. Moreover, no scaffolding is required during the welding process of the platform frames 110 and during the installation of the fixing accessories 200 onto the corresponding platform frames 110. In addition, the welding of the fixing accessories 200 to the platform frames 110 is completed before step S130, eliminating the need to move the fixing accessories 200 to a high place, effectively reducing the workload of workers.

[0068] For example, the support body 100 includes two to five platform frames 110.

[0069] In one feasible embodiment, such as Figure 3 and Figure 4 As shown, a straight ladder 111 is provided between adjacent platform frames 110, and a cover plate 1111 and a handrail 1112 are provided on the platform frame 110 above the straight ladder 111. Of course, a cover plate 1111 and a handrail 1112 can also be provided on the lowest platform frame 110, and a straight ladder 111 can also be provided below it.

[0070] In one feasible embodiment, the edge of the platform frame 110 is provided with a fence 112 to improve safety.

[0071] In this embodiment, reference continues to be made to... Figure 2 As shown, at least one first platform support 121 is provided between adjacent platform frames 110, and the first platform support 121 is located in the middle area of ​​the platform frame 110. Step S130 includes the following steps:

[0072] S131. Weld the lower end of the first platform support 121 to the corresponding platform frame 110.

[0073] S132. The upper platform frame 110 is lifted in sequence and the upper end of the first platform support 121 is welded to the corresponding platform frame 110.

[0074] Among them, the platform frame 110 is lifted by a crane.

[0075] In this embodiment, the design of the first platform support 121 enables the support body 100 to have a stable structure. Taking two adjacent platform frames 110 as an example, the first platform support 121 is first welded to the corresponding lower platform frame 110, and then the upper platform frame 110 is hoisted and welded to the upper platform frame 110 and the first platform support 121. This effectively reduces the workload of workers and ensures the safety of workers.

[0076] For example, one to three first platform supports 121 are provided between adjacent platform frames 110.

[0077] In this embodiment, reference continues to be made to... Figure 2As shown, a first mast 122 is provided between adjacent platform frames 110. The first mast 122 is located at the edge of the platform frame 110. The design of the first mast 122 can further stabilize the support body 100.

[0078] For example, the first mast 122 can be welded into a ring-shaped mesh, that is, only one first mast 122 can be provided between adjacent platform frames 110.

[0079] For example, the first mast 122 can be welded into a grid-like shape, that is, multiple first masts 122 can be set between adjacent platform frames 110, for example, two to six, and they can be set at equal intervals.

[0080] Specifically, in step S130, after all the first platform supports 121 between two adjacent platform frames 110 are welded, a first mast 122 is welded between them. The two platforms refer to the two adjacent platform frames 110 that have just been welded to the first platform supports 121. The first mast 122 is used for reinforcement. When another platform frame 110 is lifted and welded, the stability between the platform frames 110 that have been welded below can be guaranteed, and the lower platform frame 110 can be prevented from tilting when the upper platform frame 110 overlaps.

[0081] In this embodiment, reference continues to be made to... Figure 2 As shown, a second platform support 131 and a second mast 132 are provided below the lowest platform frame 110.

[0082] For example, the second platform pillar 131 is provided with at least one, such as one to three.

[0083] For example, the second mast 132 can be welded into a ring-shaped mesh, that is, only one second mast 132 can be provided between adjacent platform frames 110.

[0084] For example, the second mast 132 can be welded into a grid-like shape, that is, multiple second masts 132 can be set between adjacent platform frames 110, for example, two to six, and they can be set at equal intervals.

[0085] Specifically, in step S131, before welding the first platform support 121 to the lowermost platform frame 110, welding the second platform support 131 and the second mast 132 to the lowermost platform frame 110 can effectively improve the efficiency of welding the support body 100.

[0086] For example, the lowest platform frame 110 can be rotated 180° before welding the second platform support 131 and the second mast 132, facilitating operation. After welding the second platform support 131 and the second mast 132, the lowest platform frame 110 can be rotated 180° again, and the first platform support 121 can be welded on top of the lowest platform frame 110, effectively ensuring worker safety. Of course, the first platform support 121, the first mast 122, the second platform support 131, and the second mast 132 can also be welded to the material first, and then the material can be welded into the lowest platform frame 110, or the welding can be completed in other orders; this application does not limit this.

[0087] In this embodiment, reference continues to be made to... Figure 2 As shown, a mast 140 is provided above the uppermost platform frame 110. Specifically, in step S132, before lifting the uppermost platform frame 110, the mast 140 is welded to the uppermost platform frame 110 to avoid lifting the mast 140 to a high position alone, thus effectively improving the efficiency of welding the support body 100.

[0088] Specifically, a footboard 141 is provided on the mast 140 to facilitate climbing.

[0089] Specifically, a lightning rod 142 and an antenna 143 are provided at the top of the mast 140. The lightning rod 142 and the antenna 143 can be installed after the support body 100 is fixedly installed on the ship.

[0090] In this embodiment, reference continues to be made to... Figure 2 As shown, the mounting accessory 200 includes a guide rail bracket 210, a radar support 220, and an automatic tracking antenna support 230, while the signaling device 300 includes a whistle (not shown), a radar 310, and an automatic tracking antenna 320. Of course, other components may also be included near the mounting, and the signaling device 300 may also include other devices; this application does not limit the scope of the invention.

[0091] Specifically, step S300 includes the following steps:

[0092] S310. Install the whistle onto the guide rail bracket 210;

[0093] S320. Install radar 310 onto radar mount 220;

[0094] S330, Install the automatic tracking antenna 320 on the automatic tracking antenna support 230.

[0095] For example, taking a support body 100 comprising two platform frames 110, a guide rail support 210 and a radar support 220 are mounted on the lower platform frame 110, and an automatic tracking antenna support 230 is mounted on the upper platform frame 110. The guide rail support 210 is located at the edge of the platform frame 110 and outside the fence 112. To ensure safety, a notch is provided at the location corresponding to the guide rail support 210 in the fence 112, and a movable chain 1121 is installed at the notch.

[0096] For example, the support body 100 is also equipped with auxiliary tools such as a flag rope pulley, a flag rope, a locking device eye plate, a whistle control device wire rope, and a stabilizing device rigging, and the auxiliary tools are installed on the platform frame 110 between steps S110 and S130. The above-mentioned auxiliary tools are prior art, and will not be described in detail in this application.

[0097] To ensure the normal operation of the whistle, a compressed air pipe (not shown) is also provided on the main body 100 of the support. The whistle is connected through the compressed air pipe to provide compressed air for the whistle.

[0098] Further, step S100 includes:

[0099] S140. Install a pipe support on the support body 100 and fix a compressed air pipe on the pipe support.

[0100] The pipe support can be fixed to the support body 100 by welding or threaded connection.

[0101] For example, the installation of the pipe support can be completed before step S130, and the installation of the compressed air pipe can be completed after step S130.

[0102] In this embodiment, reference continues to be made to... Figure 2 As shown, the radar mast also includes multiple signal lights (not shown).

[0103] Specifically, the following steps are included after step S200:

[0104] S400. Install the signal light onto the bracket body 100.

[0105] The installation of the signal device 300 and the signal light is not sequential. The signal light is installed after the bracket body 100 is fixedly installed on the ship, which reduces the risk of collision with the signal light and provides a certain degree of protection for the signal light.

[0106] For example, signal lights can be installed on the edges of the platform frame 110. Specifically, signal light holders 150 are provided on the edges of the platform frame 110, and the signal lights are installed on the signal light holders 150.

[0107] To ensure the normal operation of the signal device 300 and signal lights, a cable (not shown) is also installed on the bracket body 100. The cable can be a flexible waveguide cable to meet the laying requirements on the ship. To ensure the integrity of the cable, i.e., to avoid splicing, the cable is laid after the bracket body 100 is fixedly installed on the ship.

[0108] In this embodiment, the following steps are included between step S100 and step S200:

[0109] S101. Spray paint on the main body 100 of the bracket.

[0110] In this embodiment, the service life of the bracket body 100 can be extended by spray painting.

[0111] Furthermore, the following steps are included between step S100 and step S101:

[0112] S1011, Seal both ends of the compressed air pipe.

[0113] In this embodiment, by sealing both ends of the compressed air pipe, paint is prevented from entering the compressed air pipe and affecting the connection between the compressed air pipe and the whistle.

[0114] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
