Description

Technical Field

[0001] This utility model relates to a guide rail fixing structure, specifically a guide rail fixing structure for the bottom of a push rod type normalizing furnace. Background Technology

[0002] In the existing technology, the bottom guide rail of the pusher-type normalizing furnace is usually fixed by prefabricated guide rail bricks. After the guide rail bricks are laid at the bottom of the furnace, the guide rail is placed directly in the groove of the guide rail brick.

[0003] The existing technology with the above structure suffers from low load-bearing capacity and weak load-bearing capacity due to the limited strength of the guide rail bricks. During the production process, there are also cases where the weight of the workpiece exceeds the load-bearing limit of the guide rail bricks, causing the guide rail to crack or even break, resulting in a short service life. This, in turn, affects the straightness and parallelism of the guide rail, causing the material tray to tip over when exiting the rail in the furnace, thus disrupting normal production. Utility Model Content

[0004] This utility model proposes a pusher-type normalizing furnace guide rail fixing structure, which aims to overcome the above-mentioned shortcomings of the existing technology, improve the load-bearing capacity of the guide rail, and extend its service life.

[0005] The technical solution of this utility model is a pusher-type normalizing furnace guide rail fixing structure, which includes a furnace body, guide rail units, and columns. Two rows of columns are arranged along the length of the bottom of the furnace body, with each row evenly spaced and the two rows of columns positioned adjacent to each other. A refractory castable beam is cast along each row of columns, covering the column except for its top. A guide rail composed of several guide rail units is mounted on each row of columns, and several rollers are arranged along the length of the guide rail. A material tray is supported on the rollers on both sides, and workpieces are placed on the material tray. The column-supported guide rail structure improves load-bearing capacity and structural strength, making it sturdy and durable. It can effectively increase the furnace loading capacity, increase output, and extend the overall service life of the pusher-type normalizing furnace.

[0006] Preferably, the furnace body includes bottom insulation bricks at the bottom and arched furnace top and wall insulation cotton on the top of the insulation bricks. The bottom insulation bricks are laid between and on the outside of the refractory castable beams on both sides. The bottom insulation bricks and the inner side of the furnace top and wall insulation cotton form a furnace cavity. The furnace wall insulation cotton and the bottom insulation bricks wrap the furnace body steel structure on the outside.

[0007] Preferably, a positioning square block is provided at the lower part of one end of the guide rail unit, and a rectangular guide block is provided at the lower part of the other end of the guide rail unit. Several U-shaped grooves are evenly spaced along the top of the guide rail unit, and a roller is provided in each U-shaped groove.

[0008] Preferably, the column comprises an upper square tube, a connecting steel plate, a lower column, and a base plate that are interconnected. A rectangular guide groove is connected to one side of the upper square tube, and an upper reinforcing rib is connected between the other side of the upper square tube and the top surface of the connecting steel plate. An upper triangular rib is connected between the bottom of the rectangular guide groove and one side of the upper square tube and the top surface of the connecting steel plate. A lower reinforcing rib is connected between the side of the lower column and the upper reinforcing rib on the same side as the lower reinforcing rib and the bottom surface of the connecting steel plate and the top surface of the base plate. The top of the rectangular guide groove and the upper square tube protrudes from the top surface of the refractory castable beam, and the gap between the refractory castable beam and the column is filled with thermal insulation cotton.

[0009] Preferably, when the guide rail unit is connected to the column, the positioning square block is placed in the square inner cavity of the upper square tube for positioning, and the rectangular guide block is placed in the rectangular guide groove for guidance and limitation.

[0010] The advantages of this utility model are: its reasonable structural design, employing a column-supported guide rail structure, improves load-bearing capacity and structural strength, making it sturdy and durable. It can effectively increase the furnace loading capacity, boost output, and extend the overall service life of the pusher-type normalizing furnace. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0020] like Figure 1 , 2 As shown, a pusher-type normalizing furnace guide rail fixing structure includes a furnace body, guide rail units 6 and columns 9. Two rows of columns 9 are arranged along the length direction at the bottom of the furnace body. Each row of columns 9 is evenly spaced and the two rows of columns 9 are arranged adjacent to each other. A refractory castable beam 7 is cast along each row of columns 9. The refractory castable beam 7 covers the part of the column 9 except for the top. A guide rail composed of several guide rail units 6 is mounted on each row of columns 9. Several rollers 5 are arranged along the length direction of the guide rail. The material tray 4 is supported on the rollers 5 on both sides and the workpiece 3 is placed on the material tray 4.

[0021] During actual construction, the refractory castable beams are poured in 7 sections, leaving expansion joints.

[0022] During operation, multiple material trays 4 are placed side by side on rollers 5. The material trays 4 roll on the rollers 5 along the guide rail, which drives the workpieces 3 on the material trays 4 to move in the furnace cavity (the power comes from the pusher cylinder outside the furnace, which pushes the first material tray 4, so that the whole row of material trays 4 moves in the furnace cavity).

[0023] Specifically, the furnace body includes a bottom insulation brick 8 set at the bottom and an arched furnace top and wall insulation cotton 2 set on the top of the insulation brick 8. The bottom insulation brick 8 is built between and on the outside of the refractory castable beams 7 on both sides. The bottom insulation brick 8 and the inner side of the furnace top and wall insulation cotton 2 form a furnace cavity. The outer side of the furnace wall insulation cotton 2 and the bottom insulation brick 8 wraps the furnace body steel structure 1.

[0024] like Figure 3 , 4 As shown, the guide rail unit 6 is integrally cast from heat-resistant steel. A positioning square block 61 is set at the lower part of one end of the guide rail unit 6 as a fixed end, and a rectangular guide block 62 is set at the lower part of the other end of the guide rail unit 6 as an expansion end. Several U-shaped grooves 63 are evenly spaced along the top of the guide rail unit 6, and a roller 5 is set in each U-shaped groove 63.

[0025] like Figure 5-7 As shown, the column 9 includes an upper square tube 93, a connecting steel plate 95, a lower column 96, and a base plate 98 that are connected to each other. A rectangular guide groove 91 is connected to one side of the upper square tube 93, and an upper reinforcing rib 94 is connected between the other side of the upper square tube 93 and the top surface of the connecting steel plate 95. An upper triangular rib 92 is connected between the bottom of the rectangular guide groove 91 and one side of the upper square tube 93 and the top surface of the connecting steel plate 95. A lower reinforcing rib 97 is connected between the side of the lower column 96 and the upper reinforcing rib 94 on the same side as the lower reinforcing rib 94 and the bottom surface of the connecting steel plate 95 and the top surface of the base plate 98.

[0026] The top of the rectangular guide groove 91 and the upper square tube 93 protrudes from the top surface of the refractory castable beam 7, and the gap between the refractory castable beam 7 and the column 9 is filled with thermal insulation cotton 99.

[0027] To save costs, the upper and lower parts of the column 9 are preferably made of different materials. The rectangular guide groove 91, the upper triangular rib 92, the upper square tube 93 and the upper reinforcing rib 94 are made of heat-resistant steel, while the connecting steel plate 95, the lower column 96, the lower reinforcing rib 97 and the base plate 98 are made of carbon steel.

[0028] When the guide rail unit 6 is connected to the column 9, the positioning square block 61 is placed in the square inner cavity of the upper square tube 93 for positioning, and the rectangular guide block 62 is placed in the rectangular guide groove 91 for guidance and limitation.

[0029] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
