[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-2 , Figure 1 A schematic diagram of the structure of a split furnace cover of a large kiln furnace cover steel structure provided in this utility model embodiment; Figure 2 A front structural schematic diagram of one embodiment of the steel structure for a large kiln cover provided in this utility model.

[0024] In one specific embodiment, the large kiln cover steel structure includes a cover body, which includes multiple cover sections 10. Each cover section 10 is provided with a connector 20, and the multiple cover sections 10 are connected by the connector 20 to form the cover body.

[0025] By manufacturing large kiln covers in multiple sections, which can be disassembled or manufactured independently, their size and weight are greatly reduced, facilitating indoor construction in limited spaces and overcoming the difficulties of indoor-outdoor transfer. At the same time, the restrictions on the choice of transport vehicles are reduced. Finally, the main body of the kiln cover is formed by connecting parts 20, restoring the functionality of the large kiln cover. It is easy to install and effectively solves the problem of limited space in the process of manufacturing, transporting and installing the steel structure of large kiln covers.

[0026] This application does not limit the structure, quantity, shape, setting position and connection method of the connector 20. The connector 20 is set on the top of the furnace cover part 10 or on the connecting surface of the furnace cover part 10.

[0027] This application does not limit the connection method of the furnace cover parts 10. Adjacent furnace cover parts 10 are connected by the connector 20 or by bolts.

[0028] To improve the reliability of the connection, in one embodiment, the connector 20 is disposed on the connection surface of the furnace cover segment 10. The connector 20 is a connecting flange, which is welded to the furnace cover segment 10, and adjacent furnace cover segments 10 are bolted together through the connecting flange.

[0029] By setting a connecting surface in the furnace cover segment 10 and using a connecting flange as a connector 20, the connecting flange is welded to the furnace cover segment 10, and adjacent furnace cover segments 10 are connected by connecting flange bolts, which improves the reliability of the connection method with the furnace cover segment 10, as well as the reliability and efficiency of the connection between adjacent furnace cover segments 10.

[0030] This application does not limit the structure of the connecting surface. The connecting surface of adjacent furnace cover parts 10 is a curved surface or a plane, or a combination of curved surface and plane.

[0031] This application does not limit the surface structure; it can be a sphere, a cone, a hyperboloid, or other surfaces.

[0032] To reduce the difficulty of the process, in one embodiment, the connecting surface of adjacent furnace cover parts 10 is parallel to the long or short side of the furnace cover body.

[0033] By aligning the connecting surface with the long or short side of the furnace cover body, the difficulty of subsequent installation can be reduced.

[0034] In addition to the structure described above, this application can also first design the frame of the furnace cover body, which includes the connecting surface and the four sides. Finally, in use, the furnace cover part 10 can be directly installed on the frame, which is highly efficient.

[0035] The frame can be designed in a suitable shape as needed, such as a central hexagonal structure. The adjacent furnace cover bodies should share a common edge, and the edge should be supported by profiles, such as angle steel.

[0036] In order to reduce the difficulty of transportation, in accordance with the laws and regulations of the transportation department, while strictly avoiding exceeding the width and weight limits of the sections, the weight of the difficult parts is distributed as evenly as possible.

[0037] This application does not limit the shape and size of the furnace cover detachment 10.

[0038] To further enhance the structural strength, in one embodiment, the steel structure of the large kiln cover also includes reinforcing ribs 40 and lifting lugs 30 disposed on the main body of the cover, wherein the reinforcing ribs 40 or lifting lugs 30 are installed on the same cover body 10.

[0039] By designing reinforcing ribs 40 and lifting lugs 30, the former can improve the overall strength of the furnace cover, while the latter can facilitate the stress during hoisting.

[0040] This application does not limit the shape, size, or placement of the reinforcing rib 40 and the lifting lug 30.

[0041] If the original furnace cover structure is to be disassembled, the reinforcing ribs 60 and the lifting lugs 30 must be avoided to prevent a decrease in its structural strength.

[0042] This application does not limit the structure of the furnace cover body 10. In one embodiment, the furnace cover body 10 includes multiple flat steel plates and multiple I-beam structures. The multiple I-beam structures are parallel to at least one of the long or short sides of the furnace cover body, and adjacent flat steel plates are welded through the I-beam structures.

[0043] The furnace cover is formed by welding flat steel plates and I-beams together. The structure is simple and can be connected by welding or bolts.

[0044] To further improve the reliability of the equipment, in one embodiment, the steel structure of the large kiln cover also includes flat washers and spring washers on both sides of the cover body 10. The bolts connecting the cover body 10 and the connecting flange pass through the flat washers and spring washers to bolt the cover body 10 and the connecting flange together.

[0045] During the connection process, the connecting flange has through holes around its circumference. Bolts and nuts need to be inserted into the mating flange to connect the two parts of the furnace body. Flat washers and spring washers are placed on both sides of the flange hole when the bolts are inserted into the flange hole, and finally tightened with nuts.

[0046] By setting a flat washer and a spring washer at the bottom of the furnace cover split 10, the washer is used in conjunction with the bolt and nut to prevent the nut from loosening, thus improving the reliability of use.

[0047] In one embodiment, the steel structure of the large kiln cover is implemented in the following way:

[0048] The entire furnace cover is disassembled into two sections along the centerline for construction. Flanges are welded to the cross-sectional ends of the two furnace cover sections. After transportation, they are connected as one unit with bolts and nuts and then put into use.

[0049] The above structure has the following advantages:

[0050] This invention disassembles the large kiln cover into two sections for easier construction in confined indoor spaces, overcoming the difficulties of indoor-outdoor relocation and reducing restrictions on the choice of transport vehicles. Connecting the two sections with flanges, bolts, and nuts restores the functionality of the large kiln cover and facilitates installation. This invention effectively solves the problem of limited space during the fabrication, transportation, and installation of large kiln cover steel structures.

[0051] The implementation process is as follows:

[0052] The furnace cover is divided into two sections for construction, with the center line as the boundary. Flanges are welded to the ends of each section, and a certain number of bolts and nuts are installed. The dividing line should be chosen to avoid the location of the reinforcing rib 40 and the lifting lug 30. After transportation, the sections are assembled. The entire process is as follows: section design—construction and fabrication—connection—commissioning.

[0053] In summary, the large kiln cover steel structure provided by this utility model embodiment, by manufacturing the large kiln cover in multiple sections (which can be disassembled or manufactured independently), greatly reduces the size and weight of individual components, facilitating indoor construction in limited spaces, overcoming the difficulties of indoor-outdoor transfer, and reducing restrictions on the choice of transport vehicles. Finally, the main body of the kiln cover is formed by connecting and assembling with connectors, restoring the functionality of the large kiln cover, and facilitating installation. It effectively solves the problem of limited space in the manufacturing, transportation, and installation of large kiln cover steel structures.
