Description

Technical Field

[0001] This utility model relates to the field of solution furnace rollers, and in particular to a tool for replacing solution furnace rollers. Background Technology

[0002] Roller hearth furnaces are mainly used for heating alloy steel. The main material of the furnace rollers is fiber. The fiber layer is prone to wear, cracking and falling off when exposed to a high temperature of 1250℃ for a long time. The original diameter of the furnace roller is 330mm. When the diameter of the furnace roller is worn down to 200mm, it needs to be replaced. The two ends of the furnace roller are the drive side and the non-drive side, respectively. The drive side is connected to the rotating mechanism through a coupling, thereby driving the furnace roller to rotate. The non-drive side is connected to the bearing for support. A bushing is set on the furnace roller shaft on the non-drive side. When replacing the furnace roller, the bushing needs to be removed and installed on the new furnace roller.

[0003] Traditional replacement methods rely on overhead cranes, requiring 9 people to work together for 5 hours, with 1.5 hours spent coordinating with the crane. This presents the following safety hazards: 1. Confined space operation: The furnace interior is narrow, making it difficult for personnel to move and increasing the risk of poisoning and suffocation; 2. Frequent crane lifting: Frequent crane operation poses a risk of collisions between equipment and personnel during lifting; 3. Labor-intensive operation: Poor communication among multiple people can lead to misoperation, increasing the probability of accidents. Utility Model Content

[0030] Example 1; as Figure 1 , Figure 7 As shown, this embodiment provides a tool for replacing furnace rollers in a solution treatment furnace, including an in-furnace tool 3, a drive-side tool 2, and a non-drive-side tool 1. The drive-side tool 2 is used to disengage the furnace roller shaft on the drive side of the furnace roller 4 from the bearing seat 5. The non-drive-side tool 1 is used to disengage the furnace roller shaft 41 on the non-drive side 43 of the furnace roller 4 from the bushing 6. The in-furnace tool 3 is used to support and lift the furnace roller 4.

[0031] like Figure 4 , Figure 7 As shown, the non-drive side tool 1 includes a mounting plate 12, a bracket 11, and a jack 14. The bracket 11 is used to mount the jack 14. The mounting plate 12 is used to engage the bushing 6 on the furnace roller shaft 41 of the non-drive side 43 of the furnace roller 4. The bracket 11 and the mounting plate 12 are arranged perpendicularly and welded together. The bushing 6 has a groove, and the mounting plate 12 engages the bushing 6. The output end of the jack 14 on the bracket 11 abuts against the end face of the furnace roller shaft 41 of the non-drive side 43 of the furnace roller 4. The jack 14 pushes the furnace roller shaft 41 out of the bushing 6 in the direction of the furnace roller 4, thereby removing the bushing 6 from the furnace roller shaft 41. The removed bushing 6 needs to be installed on a new furnace roller 4.

[0032] like Figure 5As shown, the transmission side tool 2 includes a mounting block 22, a second bracket 21, and a second jack 24. The second bracket 21 has mounting blocks 22 at both ends, which are connected to the bearing seats 5 on the transmission side 42 of the furnace roller 4. The second bracket 21 is equipped with the second jack 24. The output end of the second jack 24 abuts against the end face of the furnace roller shaft 41 on the transmission side 42 of the furnace roller 4. The second jack 24 pushes the furnace roller shaft 41 out of the bearing seat 5 in the direction of the furnace roller 4.

[0033] like Figure 1 , Figure 2 As shown, after the furnace roller 4 is detached from the bearings at both ends, it is placed on the furnace tool 3. The furnace tool 3 includes a jack 38, a support 31, and a base 32. The support 31 is movably connected to the base 32. The jack 3 is installed on the base 32. The output end of the jack 38 abuts against the support 31, driving the support 31 to move up and down. The furnace roller 4 is placed on the support 31. Through the drive of the jack 38, the furnace roller 4 is lifted. After being lifted, the furnace roller 4 is transported to the storage point by a crane.

[0034] Example 2: Figure 1 , Figure 4 , Figure 6 , Figure 7 As shown, this embodiment provides a tool for replacing the furnace roller 4 of a solution treatment furnace based on Embodiment 1. The mounting plate 12 has a U-shaped groove 13, and the bushing 6 has a retaining groove 61. The U-shaped groove 13 and the retaining groove 61 on the bushing 6 are fitted together. The bracket 11 has a U-shaped structure, with both ends vertically positioned on the sides of the mounting plate 12. When the mounting plate 12 is engaged in the retaining groove 61 of the bushing 6, the bracket 11 is located in front of the furnace roller shaft. The jack 14 on the bracket 11 is located on the axis of the furnace roller shaft 41, with the output end of the jack 14 abutting against the center of the end face of the furnace roller shaft 41. The furnace roller 4 is pushed out by the jack 14, thereby disengaging the furnace roller shaft 41 from the bushing 6. The bracket 11 is cut and welded from a 500×50×25mm steel plate, and the jack 14 is a 25-ton jack.

[0035] like Figure 1 , Figure 5As shown, bracket 21 has a U-shaped structure. Mounting blocks 22 are welded to the ends of the side rods on both sides of bracket 21. Mounting blocks 22 have bolt holes 23, which are used to connect to the bearing seat 5 via bolts. Bracket 21 is fixed to the bearing seat 5. A jack 24 is placed on the middle rod of bracket 21, positioned on the axis of the furnace roller 4. The output end of the jack 24 rests against the center of the furnace roller shaft end face. The jack 24 pushes the furnace roller 4 off the bearing seat 5, thus detaching the furnace roller shaft from the bearing seat 5. Bracket 21 is made of 1000*60*25mm steel plate, cut and welded. Jack 24 is a 10-ton screw jack, and M30mm nuts are used to fix the mounting blocks 22 to the bearing seat 5 on the transmission side.

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, support frame 31 includes a rectangular frame 34 and a movable frame 35. The rectangular frame 34 is a rectangular frame structure welded from four channel steels. Several rollers 33 are installed inside the rectangular frame 34, arranged in parallel. The two ends of the rollers 33 are respectively installed on the inner side of the rectangular frame 34 to support the furnace roller 4. The movable frame 35 is installed at both ends of the rectangular frame 34. The movable frame 35 is an H-shaped structure welded from three channel steels. One end of the movable frame 35 is welded to the rectangular frame 34, and the other end is slidably connected to the base 32. The base 32 includes two long rods 37 and H-shaped frames 36 welded to both ends of the long rods 37. The H-shaped frame 36 is an H-shaped structure welded from three channel steels. One end of the movable frame 35 is set in the groove of the channel steel. Jack 38 is set on the crossbar of the H-shaped frame 36, and its output end abuts against the crossbar of the movable frame 35. Two jacks 38 push the movable frame 35 upwards, and the rectangular frame 34 and the furnace roller 4 on it move upwards together, thus lifting the furnace roller 4 and facilitating its hoisting.

[0037] Jack 38 uses a 10-ton screw jack, and the rectangular frame 34 is equipped with 12 rollers 33. The movable frame 35 is made of 80mm channel steel, and the base 32 is made of 100mm channel steel. The channel steel on the movable frame 35 can be set in the groove of the channel steel of the H-shaped frame 36 to realize the movable connection between the movable frame 35 and the base 32.

[0038] In use, first use the non-drive side tool 1 to pull out the bushing 6 on the non-drive side 43 of the furnace roller 4. Then, use the furnace inside tool 3 to lift the corresponding furnace roller 4. Next, install the drive side tool 2 on the bearing seat 5 and push the furnace roller 4 out of the bearing seat 5 to disassemble the furnace roller 4. Finally, use a crane to lift the furnace roller 4 to the storage point.

[0039] 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 improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
