Based on the above, the floating section is divided into a first section and a second section from the middle, and the first section and the second section are connected in a plugging manner.
Based on the above, the socket vertically penetrating the socket is formed at the plug-in end of the first section, the plug-in end of the second section is provided with a plug mutually matched with the socket, and the plug and the socket are locked together through bolts.
Based on the above, the cross section of the suspended section is square.
Based on the above, a row of mounting holes are formed in the middle lower part of the fin from top to bottom.
Compared with the prior art, the utility model has substantial characteristics and progress, in particular to the utility model, by arranging the mounting holes on the fins of the membrane water-cooled walls at the two sides, the support rod is convenient to mount and form support from the two ends, the top of the suspended section is movably connected with the bottom-supporting vertical plate through the slot, a thermal expansion gap is reserved between the mounting holes and the threaded section, and when the thermal expansion and the cold contraction are carried out, the gaps can digest deformation and avoid generating stress, and the utility model has the advantages of no weld cracking risk and convenient disassembly and assembly.
Further, the suspension section is divided into the first section and the second section, and the first section and the second section are respectively arranged in the mounting hole and then spliced together, so that the support rod is convenient to mount; the cross section of the suspension section is square, so that the support of the coiled pipe is more stable; the arrangement of the mounting holes is convenient for adjusting the mounting height of the coiled pipe.
