[0029] Example 1

[0030] like Figure 1 As shown;

[0031] A D-type boiler water-cooled wall lower support structure comprises a D-type boiler body 1 and a base 4.

[0032] In this implementation scheme: as disclosed in the background technology above, "the original D-type boiler water-cooled wall lower support structure adopts a platform formed by welding a group of integral steel sections, which consumes a large amount of steel; and due to the large amount of steel used and its huge weight, it may even affect the overall linear expansion of the boiler; since the platform frame area is very large, especially for large-tonnage boilers, it is even impossible to transport it as a whole, and can only be shipped in parts to the construction site for splicing, increasing the workload on site." Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a boiler support assembly 2 and a water-cooled wall support assembly 3 are added on this basis.

[0035] In this embodiment: before the D-type boiler body 1 needs to be installed, the fixing steels 23 at both ends of the concave steel 21 are fixed to the top of the base 4 by expansion nails 26 according to the installation position of the D-type boiler body 1, and the horizontal length of the concave steel 21 is adjusted during processing according to the installation width of the D-type boiler body 1.

[0036] In an optional embodiment, a first rib 24 is fixed on both sides of the concave steel 21, a second rib 25 is fixed on the top of the fixed steel 23, and a triangular support frame 22 is arranged between the first rib 24 and the second rib 25. One end of the triangular support frame 22 is welded to the first rib 24, and the other end of the triangular support frame 22 is welded to the second rib 25.

[0037] In this embodiment: in order to support the structure of the concave steel 21 and ensure the overall stability of the device, triangular supports 22 are provided on both sides of the concave steel 21 and fixed by a first support rib 24 and a second support rib 25. The device is integrally formed and can be directly installed on the D-type boiler body 1 after being transported to the site.

[0038] In an optional embodiment, through holes are formed through the front ends of both sides of the fixing steel 23, and expansion nails 26 are arranged inside the through holes.

[0039] In this embodiment: before the D-type boiler body 1 needs to be installed, the installation position of the D-type boiler body 1 is first determined.

[0040] In an optional embodiment, a pipe groove 27 is formed through the surface of the concave steel 21 .

[0041] In this embodiment, the pipe groove 27 is used to reserve the external connection of the pipe of the D-type boiler body 1.

[0044] In this implementation scheme: the two supporting steel plates are welded to the I-beams and directly shipped to the construction site. During installation, the water-cooled wall only needs to be directly placed on the I-beams.

[0045] In an optional embodiment, one end of the L-shaped support steel 31 is welded to the top of the I-shaped steel 32 through two sets of welding ribs 33 .

[0046] In this embodiment, the L-shaped support steel 31 and the I-shaped steel 32 are fixed by welding ribs 33 .

[0047] The working principle and use process of the utility model are as follows: before the D-type boiler body 1 needs to be installed, the fixing steels 23 at both ends of the concave steel 21 are fixed to the top of the base 4 through expansion nails 26 according to the installation position of the D-type boiler body 1, and then the position of the I-shaped steel 32 is adjusted according to the water-cooled wall of the D-type boiler body 1 for fixing, and then the D-type boiler body 1 can be directly installed on the top of the concave steel 21.

[0048] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
