[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] like Figures 1 to 5 As shown, a device for replacing the bottom roller of a tempering furnace includes a replacement frame body 1 located below the bottom roller 2 of the furnace, the bottom of the replacement frame body 1 is connected to a U-shaped fixed structure, the U-shaped fixed structure includes a horizontal frame 4 and vertical telescopic structures on both sides, a connector is connected between the horizontal frame 4 and the vertical telescopic structure, one end of the replacement frame body 1 is fixedly connected to an L-shaped plate 3, the bottom of the vertical plate of the L-shaped plate 3 and the bottom of the two vertical telescopic structures are respectively fixedly connected to brake casters 6, a top surface of the horizontal frame 4 is provided with a movable groove 16, a movable block 18 is slidably connected in the movable groove 16, the top surface of the movable block 18 is fixedly connected to the bottom of one end of the replacement frame body 1, and two symmetrically arranged limit members are provided on the top of the replacement frame body 1.

[0025] Figures 1 to 5 As shown, when the tempering furnace bottom roller replacement device of the present invention is in use, when the worker needs to replace the furnace bottom roller 2, the horizontal frame 4 and the vertical telescopic structures on both sides can be installed on both sides of the conveyor bed through the plug-in parts, so that the U-shaped fixed structure is located on both sides of the conveyor bed, and is fixed with the brake casters 6. Then, the L-shaped plate 3 is placed on the outside of the vertical telescopic structure at one end, and the moving block 18 at the bottom of the replacement frame body 1 is driven into the moving groove 16 on the top surface of the horizontal frame 4. At this time, the installation is completed, and the brake casters 6 can be stepped on to achieve the stability of the L-shaped plate 3, which ensures that the replacement frame body 1 does not move on the top surface of the horizontal frame 4.

[0026] When in use, the mounting bearings at both ends of the hearth roller 2 are removed from the conveyor bed, and then the worker carries the hearth roller 2 and places it on the replacement rack body 1. Subsequently, the fasteners are fixed to both ends of the hearth roller 2 to stabilize the hearth roller 2. At this time, the brakes of the brake casters 6 can be released.

[0027] Then, the L-shaped plate 3 is pulled so that the L-shaped plate 3 drives the replacement frame body 1 to move on the horizontal frame 4, so that the moving block 18 moves in the moving groove 16, as shown in FIG. Figure 3 As shown, the limiter can be opened at this time to remove the furnace bottom roller 2;

[0028] At this time, the new hearth roller 2 can be moved to the replacement frame body 1, and then the previous step is repeated until the hearth roller 2 is located above the conveyor bed that needs to be replaced. At this time, the new hearth roller 2 is moved down for installation; this reciprocating process is repeated to achieve the replacement and installation of the hearth roller 2.

[0029] When the furnace bottom roller 2 is replaced, the U-shaped fixed structure can be moved so that the horizontal frame 4 drives the L-shaped plate 3 and the vertical telescopic structure and the brake caster 6 to move, making it convenient to replace a furnace bottom roller 2.

[0030] By arranging a movable U-shaped fixed structure at the bottom of the replacement frame body 1, the brake caster 6 can be moved at any time, which is convenient for workers to move the replacement frame body 1. Through the mutual cooperation of the L-shaped plate 3, the moving block 18 and the moving groove 16, when the hearth roller 2 is located on the replacement frame body 1, there is no need to manually pull the hearth roller 2, and manpower can be saved by directly moving the replacement frame body 1.

[0031] like Figure 2 and Figure 5 As shown, the limiting member includes a fastening belt 9, one end of which is fixedly connected to the outer wall of the replacement frame body 1, and the inner wall of the other end is connected to the outer wall of the replacement frame body 1 through a Velcro structure 20, and the inner wall of the fastening belt 9 is against the outer wall of the furnace bottom roller 2.

[0032] Specifically, before and after the hearth roller 2 is moved, the fastening belt 9 can be opened, and the two ends of the hearth roller 2 can be fixed using the Velcro structure 20, so as to ensure the stability of the hearth roller 2 when the replacement frame body 1 is moved, and prevent the hearth roller 2 from falling when the replacement frame body 1 is moved.

[0033] like Figure 2 and Figure 4 As shown, the vertical telescopic structure includes a telescopic plate 7 and a side plate 5. The telescopic plate 7 is connected to the bottom surface of the end of the horizontal frame 4. A sliding groove 10 is provided in the side plate 5. The telescopic plate 7 is slidably connected in the sliding groove 10. A plurality of slots 12 are provided on the telescopic plate 7. The outer side of the side plate 5 is plugged with a plug plate 8 that passes through the slots 12.

[0034] Specifically, workers can adjust the height of the vertical telescopic structure according to the height of the conveyor bed. When adjusting, slide the side panel 5 so that the slide groove 10 slides on the outside of the telescopic plate 7. After moving to the appropriate position, insert the plug plate 8 into the slot 12 so that the plug plate 8 limits the side panel 5 and the telescopic plate 7. The adjustable height setting facilitates the improvement of the applicability and flexible use of the replacement device.

[0035] The cross-sections of the plug board 8 and the slot 12 are preferably rectangular, which makes the plugging more stable.

[0036] like Figure 2 and Figure 5 As shown, a plurality of springs 11 are fixedly connected to the bottom inner wall of the slide groove 10 , and the other end of the spring 11 is fixedly connected to the bottom surface of the telescopic plate 7 .

[0037] Specifically, when a worker slides the side panel 5, the provision of the spring 11 can play a certain auxiliary pushing role, thereby improving the convenience of sliding.

[0038] like Figure 2 、 Figure 4 and Figure 5 As shown, the connector includes two vertical blocks 15, which are symmetrically arranged and fixedly connected to the bottom surface of the end of the horizontal frame 4. The top surface of the telescopic plate 7 is provided with a vertical groove 14 corresponding to the position of the vertical block 15.

[0039] Specifically, when workers are installing the U-shaped fixed structure, they can place two vertical telescopic structures on both sides of the conveyor bed. One of the workers moves the horizontal frame 4 onto the conveyor bed and makes the vertical blocks 15 at both ends of the horizontal frame 4 plug into the vertical grooves 14 on the top of the telescopic plate 7. This not only ensures the convenient assembly of the U-shaped fixed structure, but also ensures the overall stability of the U-shaped fixed structure when the replacement frame body 1 is moved.

[0040] like Figure 5 As shown, a threaded rod 19 is fixedly connected to the bottom surface of the moving block 18 , and a threaded ring 21 is threadedly connected to the outer side of the threaded rod 19 .

[0041] Specifically, by threading the threaded ring 21 and the threaded rod 19, the moving block 18 can be stably connected in the moving groove 16 to prevent the moving block 18 from being separated from the moving groove 16. The threaded ring 21 and the threaded rod 19 are detachably connected, ensuring convenience during assembly and stability during movement of the replacement rack body 1.

[0042] like Figure 2 、 Figure 3 and Figure 5 As shown, two symmetrically arranged rolling grooves 17 are opened on the top surface of the cross frame 4, and two groups of symmetrically arranged balls 22 are embedded on the bottom surface of the replacement frame body 1. The balls 22 are located in the rolling grooves 17 for sliding and rolling connection.

[0043] Specifically, when the replacement rack body 1 moves, the balls 22 will slide and roll in the rolling grooves 17 . This arrangement can convert the original sliding friction into rolling friction, thereby making the replacement rack body 1 move more smoothly.

[0044] like Figure 1 and Figure 5 As shown, both sides of the outer wall of the end of the plugboard 8 are provided with embedding grooves 13. The provision of the embedding grooves 13 can make the plugboard 8 easy to hold when plugging.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
