Description

Technical Field

[0001] This invention relates to the field of fiber insulation module hoisting technology, specifically to a hoisting structure and method for fiber insulation modules. Background Technology

[0002] The heating furnace is a core thermal equipment in the steel rolling production line of the iron and steel industry. It is specifically used to heat steel billets (square billets, slabs, flat billets, etc.) to a uniform and suitable high-temperature state for plastic deformation before rolling (usually between 1100°C and 1300°C). Its performance directly determines the stability of the rolling process, the quality of the rolled product, energy consumption, and output. Heating furnaces have relatively high requirements for high-temperature resistance and heat preservation; poor heat preservation will result in a large amount of heat loss.

[0003] The shortcomings of existing technology:

[0004] Application No. 201610054237.7 discloses a flat regenerative furnace roof. Although the patent describes a flat regenerative furnace roof composed of several parallel modules, it is mainly for the application of all-fiber furnace roofs in large industrial furnaces such as hot rolling heating furnaces. It has significant effects, long service life, simple processing technology, and high manufacturing efficiency. However, during assembly, the steel structure and fiber module 6 are first fixedly connected by U-shaped anchors 11. During connection, self-tapping screws 13 are passed through guide rods 12 into wire blocks 14 and fixed on the sealing plate 19. After the connection is completed, the guide rods 12 are pulled out. This structure requires a channel to be reserved in the insulation module to fix the self-tapping screws. The process is complicated. Since the self-tapping screws are screwed in from bottom to top, they are easy to fall off after long-term use, and the later maintenance is cumbersome and the self-tapping screws are difficult to disassemble. Summary of the Invention

[0005] The purpose of this invention is to provide a hoisting structure and hoisting method for a fiber insulation module, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hoisting structure for a fiber insulation module, the hoisting structure comprising a steel structure for hoisting onto a furnace wall and a fiber insulation module composed of fiber cloth, the fiber insulation module and the steel structure being connected by a connecting component, the upper end of the connecting component being fixed to the steel structure, and the lower end of the connecting component passing through the steel structure and fixed to the fiber insulation module.

[0014] Preferably, the connector further includes a fixing nut, which is located at the upper or lower end of the threaded hole and fixed to the anchor plate. The lower end of the fixing bolt is threadedly connected to the fixing nut to strengthen the connection between the fixing bolt and the anchor plate.

[0015] Preferably, the hoisting plate is a grid steel plate or a steel plate with perforations.

[0038] Example 1

[0039] Please see Figure 1-7 As shown, the present invention provides a hoisting structure for a fiber insulation module. The hoisting structure includes a steel structure 1 hoisted on the furnace wall and a fiber insulation module 2 composed of fiber cloth. The fiber insulation module 2 and the steel structure 1 are connected by a connecting component. The upper end of the connecting component is fixed to the steel structure 1, and the lower end of the connecting component passes through the steel structure 1 and is fixed to the fiber insulation module 2. The fiber insulation module 2 and the steel structure 1 are connected by the connecting component. This changes the original method of fixing the fiber insulation module 2 from the lower end to the upper end, and the installation method is from top to bottom. The fiber insulation module 2 is more stably fixed to the steel structure 1, and the operation is more convenient.

[0040] The steel structure 1 includes a steel beam 101 and a hoisting plate 102. The two ends of the steel beam 101 are hoisted to the furnace wall. The hoisting plate 102 is fixedly installed at the lower end of the steel beam 101. The connecting plate 31 is fixedly installed on the upper surface of the hoisting plate 102. The hoisting plate 102 is a grid steel plate or a steel plate with open holes. The steel structure 1 is composed of the steel beam 101 and the hoisting plate 102. While reducing the overall weight, it can increase the overall strength and bearing capacity of the steel structure 1. At the same time, the hoisting plate 102 is a grid steel plate or a steel plate with open holes, which facilitates the inspection and maintenance of the fiber insulation module 2 in the later stage.

[0041] The connecting assembly includes a fixing member 3 connected to the steel structure 1 and a connector 4 fixed to the fiber insulation module 2. The lower end of the fixing member 3 is connected to the connector 4. The fixing member 3 includes a connecting plate 31 and a fixing bolt 32. The connecting plate 31 is fixedly installed on the steel structure 1, specifically by welding the connecting plate 31 to the upper surface of the hoisting plate 102. A corresponding through hole is provided on the connecting plate 31. The lower end of the fixing bolt 32 passes through the through hole on the connecting plate 31 and connects to the connector 4. Specifically, the fixing bolt 32 passes through the through hole on the connecting plate 31 and connects to the threaded structure on the connector 4. The connector 4 includes an anchoring plate 41 connected to the lower end of the fixing bolt 32 and a crossbar 42 for installing the fiber insulation module 2. The anchoring plate 41 includes a support part and a connecting part. The connecting part is integrally formed on both sides of the support part. The support part and the connecting part are formed by stamping, which is quick and simple to process and has low manufacturing cost. The support part is used to connect the hoisted steel structure 1, which overlaps the furnace wall. The connecting part is used to connect with the metal parts for inserting fiber cloth. The support section has threaded holes, and the hoisted steel structure 1 is fixed to the support section by fixing bolts 32. The fixing method is simple, quick, and provides better stability. The connecting section has through holes. By inserting a crossbar 42 into the through holes, the cut fiber cloth is stacked together and then pressed into the crossbar 42 by a stamping device. The cross-section of the support section is arrow-shaped to ensure sufficient connection strength and prevent deformation under pressure after long-term use. The connecting section is diamond-shaped, which is convenient to insert into the fiber cloth gaps while having sufficient strength to stably hoist the fiber cloth. The connecting piece 4 also includes a fixing nut 43, which is located at the upper or lower end of the threaded hole and fixed to the anchor plate 41. The lower end of the fixing bolt 32 is threaded to the fixing nut 43 to strengthen the connection strength between the fixing bolt 32 and the anchor plate 41.

[0042] The fiber insulation module 2 is made by stacking several fiber cloths into a cube, then pressing it into one end of the crossbar 42 with a press machine, and then pressing another cube made of fiber cloth into the other end of the crossbar 42. Finally, a wooden block is fixed on each side for pressing, thus completing the production of the fiber insulation module 2.

[0043] Example 2

[0044] This invention also provides a method for hoisting a fiber insulation module, which specifically includes the following steps:

[0045] S1. Weld the hoisting plate 102 to the lower end of the steel beam 101;

[0046] S2. Fix the fiber insulation module 2 to the connector 4, specifically as follows:

[0047] Several pieces of fiber cloth are stacked into a cube, and then pressed into one end of the crossbar 42 using a press. Another cube made of stacked fiber cloth is then pressed into the other end of the crossbar 42. Finally, a wooden block is fixed on each side for further compression, thus fixing the fiber insulation module 2 onto the connector 4.

[0048] S3. Connect the fiber insulation module 2 to the steel structure 1 by means of fastener 3 and connector 4. This includes the following steps:

[0049] a1. Based on the position of the fiber insulation module 2 relative to the lifting plate 102, determine the position of the connecting plate 31 on the lifting plate 102, and weld the connecting plate 31 to the upper surface of the lifting plate 102.

[0050] a2. Pass the fixing bolt 32 through the through hole on the connecting plate 31 from top to bottom, and screw the lower end of the fixing bolt 32 into the threaded hole on the anchor plate 41 and the fixing nut 43. By tightening the fixing bolt 32, the lower end of the fixing bolt 32 is fixed to the anchor plate 41, and the hoisting and fixing of the fiber insulation module 2 can be completed.

[0051] This hoisting method has been changed from bottom-up to top-down, making fixing easier and improving assembly efficiency. It eliminates the need to pre-install bolt installation pipes during the fabrication of the fiber insulation module 2, making operation more convenient and fixing more reliable.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
