Description

Technical Field

[0001] This application relates to the technical field of roll repair equipment, and in particular to insulation boxes for rolls. Background Technology

[0002] A roll insulation box is a device specifically designed to maintain the temperature of rolls, primarily used in the rolling process in industries such as steel and metal processing. This type of insulation box is designed to reduce temperature loss during the welding process of rolls during repair, thereby improving production efficiency and product quality.

[0003] To reduce heat loss from the rolls within the protective box, electric heaters are typically installed inside the box to maintain the temperature and ensure that the rolls remain within a suitable temperature range during replacement or welding. This prevents material embrittlement or reduced welding quality due to excessively low temperatures. However, in related technologies, the electric heaters are usually fixed inside the protective box and cannot be adjusted or moved according to the welding position of the rolls, resulting in poor insulation at the welding position. Utility Model Content

[0004] In order to improve the insulation effect of the roll insulation box on the weld overlay of the roll, this application provides an insulation box for rolls.

[0005] The heat preservation box for rolling mills provided in this application adopts the following technical solution:

[0006] A heat preservation box for rolling mills includes a heat preservation box body. Through holes are provided on both side walls of the heat preservation box body. A common placement plate passes through both through holes. The placement plate is arranged along the length of the heat preservation box body. A mounting block passes through and is slidably connected to the placement plate. A heater is fixedly connected to the upper end of the mounting block. A fixing component is provided at the through holes for fixing the placement plate to the heat preservation box body. A drive mechanism is provided at the heat preservation box body for driving the mounting block to slide on the placement plate.

[0007] By adopting the above technical solution, after the roll is placed inside the insulation box, the position of the placement plate can be adjusted so that the heater on the mounting block is close to the weld overlay of the roll. Then, the placement plate is fixed to the box by the fixing component. Subsequently, the mounting block can be slid by controlling the drive mechanism to move the heater directly below the weld overlay of the roll. Then, the heater is activated to heat and insulate the weld overlay of the roll. This reduces the heat loss of the heater, improves the utilization efficiency of the heater, and improves the insulation effect of the roll insulation box on the weld overlay of the roll.

[0008] Optionally, the fixing component includes a fixing plate that abuts against the side wall of the insulation box body, and a fixing bolt is threaded onto the fixing plate, with the shank of the fixing bolt threaded onto the insulation box body.

[0009] By adopting the above technical solution, the shank of the fixing bolt can be disengaged from the body of the insulation box by rotating the fixing bolt, or the fixing bolt can be threaded onto the body of the insulation box, thereby fixing the fixing plate to the body of the insulation box or removing the fixing bolt from the body of the insulation box.

[0010] Optionally, the outer wall of the heat preservation box body is provided with a plurality of fixing thread holes for the fixing bolts to be threaded together.

[0011] By adopting the above technical solution, the position of the fixing plate can be changed by connecting the fixing bolts to the threaded holes at different positions, thereby changing the position of the placement plate inside the insulation box.

[0012] Optionally, a base plate is fixedly connected to the lower end of the insulated box body, and multiple casters are rotatably connected to the lower end of the base plate.

[0013] By adopting the above technical solution, the base plate can be moved by controlling the casters, thereby moving the body of the insulated box.

[0014] Optionally, the driving mechanism includes a drive motor mounted on the base plate, a positioning component for fixing the drive motor on the base plate between the drive motor and the base plate, a drive gear fixedly connected to the output shaft of the drive motor, a rack meshing with one side of the drive gear, the rack being parallel to the placement plate, and one end of the rack passing through a fixing plate and fixedly connected to the mounting block.

[0015] By adopting the above technical solution, the drive motor can be controlled to drive the drive gear to rotate, thereby causing the rack to drive the mounting block to slide on the placement plate, thus changing the position of the heater on the mounting block inside the insulation box.

[0016] Optionally, the positioning component includes a positioning block fixedly connected to the drive motor, a positioning bolt threadedly connected to the positioning block, and a plurality of positioning threaded holes for the positioning bolt to be threadedly connected to the base plate, wherein the positioning bolt is threadedly connected to the positioning threaded holes.

[0017] By adopting the above technical solution, the shank of the positioning bolt can be disengaged from the positioning threaded hole or the positioning bolt can be threaded into the positioning threaded hole by rotating the positioning bolt, thereby realizing the disassembly or fixing of the drive motor on the base plate.

[0018] Optionally, multiple fans are fixedly connected to the bottom of the insulation box body, and the fans are arranged along the length direction of the insulation box body.

[0019] By adopting the above technical solution, the roll section after the welding is completed can be cooled by a fan, thereby accelerating the repair time of the roll at the welded area.

[0020] Optionally, the heater is configured as a resistance heater.

[0021] By adopting the above technical solution, the heating of the weld overlay area of ​​the roll can be achieved quickly using a resistance heater.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The heater can be moved directly below the area of ​​the roll that needs to be welded by controlling the drive mechanism to slide the mounting block. Then the heater is activated to heat and insulate the welded area of ​​the roll. This reduces the heat loss of the heater, improves the utilization efficiency of the heater, and improves the insulation effect of the roll insulation box on the welded area of ​​the roll.

[0024] 2. The drive motor can be controlled to drive the drive gear to rotate, which in turn causes the rack to slide the mounting block on the placement plate, thereby changing the position of the heater on the mounting block inside the insulation box.

[0025] 3. The shank of the positioning bolt can be disengaged from the positioning threaded hole or the positioning bolt can be threaded into the positioning threaded hole by rotating the positioning bolt, thereby enabling the disassembly or fixing of the drive motor on the base plate.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0030] This application discloses an insulation box for rolling mills, referring to... Figure 1 and Figure 2 The system includes an insulated box body 1, which is rectangular in shape, with arc-shaped notches for placing rollers on the upper ends of both sides in the width direction. A base plate 7, which is also rectangular in shape, is fixedly connected to the lower end of the insulated box body 1. Casters 71 are rotatably connected to the four corners of the lower end of the base plate 7.

[0031] Multiple fans 8 are fixedly connected to the bottom of the insulation box body 1 to dissipate heat from the welded area of ​​the roll after the roll has been welded. The fans 8 are equidistantly arranged along the length of the insulation box body 1. Through holes 11 are provided on both sides of the side wall in the width direction of the insulation box body 1. The through holes 11 are shaped like cuboids.

[0032] The same placement plate 2 is inserted through the two through holes 11. The placement plate 2 is rectangular. The placement plate 2 is arranged along the length of the insulation box body 1. A mounting block 3 is inserted through and slidably connected to the placement plate 2. A heater 4 is fixedly connected to the upper end of the mounting block 3. In this embodiment, the heater 4 is a resistance heater 4.

[0033] A fixing assembly 5 for fixing the placement plate 2 to the insulation box body 1 is provided at the through hole 11. The fixing assembly 5 includes a fixing plate 51, which is parallel to the side wall of the insulation box body 1 in the width direction. Two fixing plates 51 are provided, and the ends of the placement plate 2 are fixedly connected to the fixing plates 51. The fixing plates 51 abut against the side wall of the insulation box body 1. Two fixing bolts 52 are threadedly connected to the fixing plates 51. Multiple fixing threaded holes 12 are opened on the outer side wall of the insulation box body corresponding to the shank of the fixing bolts 52. In this embodiment, the fixing threaded holes 12 are arranged in two rows, and the through hole 11 is located between the two rows of fixing threaded holes 12. The shank of the fixing bolt 52 is threadedly connected to one of the fixing threaded holes 12.

[0034] By rotating the fixing bolt 52, the shank of the fixing bolt 52 can be disengaged from the threaded fixing hole 12 on the insulation box body 1, or the fixing bolt 52 can be threaded onto the insulation box body 1, thereby fixing or removing the fixing plate 51 from the insulation box body 1. Simultaneously, by threading the fixing bolt 52 into the fixing threaded holes 12 at different positions, the fixing position of the fixing plate 51 can be changed, thereby changing the position of the placement plate 2 within the insulation box body 1, thus achieving vertical adjustment of the heater 4.

[0035] The insulation box body 1 is equipped with a drive mechanism 6 for sliding the mounting block 3 on the placement plate 2. The drive mechanism 6 includes a drive motor 61 mounted on the base plate 7, and a positioning assembly 62 for fixing the drive motor 61 to the base plate 7 is provided between the drive motor 61 and the base plate 7. The positioning assembly 62 includes a positioning block 621 fixedly connected to the drive motor 61, and a positioning bolt 622 threadedly connected to the positioning block 621. The base plate 7 has multiple positioning threaded holes 72 for threaded connection of the positioning bolts 622, and the distance between two adjacent positioning threaded holes 72 is the same as the distance between two adjacent fixing threaded holes 12. The positioning bolts 622 are threadedly connected in the positioning threaded holes 72.

[0036] A drive gear 63 is fixedly connected to the output shaft of the drive motor 61. A rack 64 meshes with one side of the drive gear 63 and is positioned above the mounting plate. The rack 64 is parallel to the placement plate 2. One end of the rack 64 passes through the fixing plate 51 and is fixedly connected to the mounting block 3. The rack 64 is slidably connected to the fixing plate 51.

[0037] The drive motor 61 can be controlled to drive the drive gear 63 to rotate, which in turn causes the rack 64 to slide the mounting block 3 on the placement plate 2, thereby changing the lateral position of the heater 4 on the mounting block 3 within the insulation box body 1. Furthermore, after the position of the fixing plate 51 changes, the positioning bolt 622 can be rotated to disengage the shank of the positioning bolt 622 from the positioning threaded hole 72, and then the positioning bolt 622 can be threaded into a suitable positioning threaded hole 72, continuing to maintain the engagement between the drive gear 63 and the drive rack 64.

[0038] The implementation principle of the insulation box for rolling mills in this embodiment is as follows: After the rolling mill is placed inside the insulation box body 1, the fixing position of the fixing plate 51 can be changed by connecting the fixing bolt 52 to the fixing threaded hole 12 at different positions. This changes the position of the placement plate 2 inside the insulation box body 1, thereby adjusting the vertical direction of the heater 4. At the same time, the drive motor 61 can be controlled to make the rack 64 drive the mounting block 3 to slide on the placement plate 2, thereby changing the lateral position of the heater 4 inside the insulation box body 1. This makes the heater 4 on the mounting block 3 as close as possible to the weld overlay of the rolling mill. Finally, the heater 4 is activated to heat and insulate the weld overlay of the rolling mill.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
