Description

Technical Field

[0001] The present application relates to the technical field of furnace bottom rollers, and in particular to a furnace bottom roller for a heating furnace. Background Art

[0002] The furnace bottom rollers commonly used in heating furnaces are heavy-duty rollers that withstand high temperatures and heavy pressures, and are usually made of high-temperature alloy steel or special alloys to ensure their stability and durability in high-temperature environments.

[0003] At present, the existing Chinese patent with patent publication number CN215103412U discloses a heating furnace bottom roller, which belongs to the technical field of heating furnaces in the metallurgical industry. The technical scheme is as follows: a furnace wall base (3) is anchored on a first fixed plate (2) of a furnace shell by anchoring nails; a furnace roller (4) passes through the first fixed plate (2) of the furnace shell and the furnace wall base (3); and both ends of the furnace roller (4) are exposed outside the first fixed plate (2) of the furnace shell; both ends of the furnace roller (4) are supported on a bearing seat furnace bottom roller body (1); the bearing seat furnace bottom roller body (1) is fixed on a bracket (7); and the bracket (7) is fixed on the first fixed plate (2) of the furnace shell; an expansion joint (6) with a flange is sleeved on the furnace roller (4) outside the first fixed plate (2) of the furnace shell; both ends of the expansion joint (6) with a flange are respectively connected to the bearing seat furnace bottom roller body (1) and the furnace shell flange (8); the furnace shell flange (8) is fixed on the first fixed plate (2) of the furnace shell; a refractory sleeve (5) is sleeved on the furnace roller (4) inside the first fixed plate (2) of the furnace shell; and the refractory sleeve (5) is located between the furnace wall base (3) and the furnace roller (4). The utility model has the beneficial effect of effectively avoiding the phenomenon of the furnace bottom roller being blocked in rotation due to the furnace bottom roller being bent due to heat.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that when some existing furnace bottom rollers are installed on the heating furnace base, the fixing method is relatively complicated and takes a long time. Some of them are fixed by snap-fitting, which can only install specific types of furnace bottom rollers and is difficult to install furnace bottom rollers of different sizes. Moreover, when the furnace bottom roller is under heavy pressure, there is no protection function for it. The furnace bottom roller is under pressure for a long time, which can easily cause it to crack and reduce its service life. Utility Model Content

[0005] The present application provides a method for installing a furnace bottom roller for a heating furnace, which is simple and firm, and can fix furnace bottom rollers of different sizes at the same time. When the furnace bottom roller is under heavy pressure, it has a protective effect on the furnace bottom roller, prevents cracking due to long-term heavy pressure, and increases the service life of the furnace bottom roller.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a furnace bottom roller for a heating furnace, the furnace bottom roller comprising:

[0007] two first fixing plates;

[0008] A plurality of threaded rods are respectively fixedly arranged on one side of the two first fixing plates, and the plurality of threaded rods are evenly divided into two groups, and the outer surfaces of the two groups of threaded rods are movably embedded with second fixing plates, and the two second fixing plates have a fixing function on the furnace bottom roller;

[0009] Two first rods are fixedly arranged on the inner walls of the two second fixing plates respectively, and one side of the two first rods is movably sleeved with a second rod, and the two second rods can slide on the outer surfaces of the two first rods respectively;

[0010] Two telescopic springs are movably sleeved on the outer surfaces of the two first sleeve rods respectively, and the elastic force generated by the two telescopic springs makes the two arc-shaped pressure plates closely contact the outer surfaces of the two bearings;

[0011] Two arc-shaped pressing plates are respectively fixedly arranged on one side of the two second sets of rods, and one side of the two arc-shaped pressing plates is movably provided with bearings, and the two arc-shaped pressing plates are located on the outer surfaces of the two bearings;

[0012] A plurality of threaded cylinders are respectively threadedly sleeved on the outer surfaces of the plurality of threaded rods, and the plurality of threaded cylinders are rotated to fix the two second fixing plates on the first fixing plate.

[0013] As a further improvement of the present application: a furnace bottom roller body is arranged inside the two bearings, the inner walls of the two first fixing plates are movably arranged on the outer surfaces of the two bearings, and the furnace bottom roller body can rotate through the two bearings.

[0014] As a further improvement of the present application: a connecting platform is fixedly provided on one side of the two first fixing plates, two first connecting shafts are fixedly provided inside the two connecting platforms, and the two connecting platforms have a connecting function for the two first fixing plates.

[0015] As a further improvement of the present application: a push plate is movably mounted on the outer surfaces of the plurality of first connecting shafts, a second connecting shaft is movably embedded on one side of the plurality of push plates, and the plurality of push plates can rotate around the plurality of first connecting shafts or the plurality of second connecting shafts as axes.

[0016] As a further improvement scheme of the present application: a slide cylinder is fixedly provided on one side of the multiple second connecting shafts, the multiple slide cylinders are evenly divided into two groups, cross bars are movably embedded inside the two groups of slide cylinders, and the multiple slide cylinders can slide on the outer surfaces of the two bases respectively.

[0017] As a further improvement of the present application: a plurality of extrusion springs are fixedly provided on one side of the slide cylinders, the inner walls of the plurality of extrusion springs are movably sleeved on the outer surfaces of the two cross bars, and the plurality of extrusion springs will generate a reverse force when being squeezed.

[0018] As a further improvement of the present application: a base is fixedly provided on both sides of the two cross bars, and two through holes are provided on one side of the base close to the two cross bars, so that the two cross bars can be installed on the base.

[0019] As a further improvement scheme of the present application: multiple positioning holes are respectively opened on one side of the two second fixed plates, and the outer surfaces of the multiple threaded rods are respectively movably embedded in the interior of the multiple positioning holes. The threaded rods are inserted into the interior of the multiple positioning holes so that the two second fixed plates are located above the two first fixed plates.

[0020] Compared with the prior art, the advantages and positive effects of this application are:

[0021] 1. In the present application, when the furnace bottom roller needs to be installed, two bearings are put on the two ends of the furnace bottom roller body, and then they are placed inside the two first fixing plates respectively. At this time, the threaded rods are inserted into the interior of the multiple positioning holes respectively, so that the two second fixing plates are above the two first fixing plates, and then the multiple threaded cylinders are rotated to fix the two second fixing plates on the first fixing plates, and the two arc-shaped pressure plates are on the outer surfaces of the two bearings, and the two second sets of rods can slide on the outer surfaces of the two first sets of rods respectively. In the process of pressing down the two second fixing plates, the two arc-shaped pressure plates are pressed down by the two second sets of rods, and the elastic force generated by the two telescopic springs makes the two arc-shaped pressure plates close to the outer surfaces of the two bearings, further improving the fixing effect of the furnace bottom roller body, so that the installation method of the furnace bottom roller body is simple and firm, and at the same time, the mobility of the two arc-shaped pressure plates can fix furnace bottom roller bodies of different sizes.

[0022] 2. In the present application, when the furnace bottom roller body is under heavy pressure, the pressure is transmitted to the two first fixed plates through the furnace bottom roller body. Because the multiple push plates can rotate with the multiple first connecting shafts or the multiple second connecting shafts as axes, the multiple slide cylinders can slide on the outer surfaces of the two cross bars respectively, so that the first fixed plate passes through the multiple connecting platforms, so that the multiple push plates push the multiple slide cylinders respectively, so that the multiple slide cylinders squeeze the multiple squeezing springs. The multiple squeezing springs will generate a reverse force when squeezed, which can offset a part of the force exerted on the furnace bottom roller body, thereby protecting the furnace bottom roller body, preventing the furnace bottom roller body from being subjected to heavy pressure for a long time and cracking due to lack of protection function, thereby increasing the service life of the furnace bottom roller body.

However, the present application may also be implemented in other ways different from those described herein. Therefore, the present application is not limited to the specific embodiments of the following disclosure.

[0031] Embodiment 1, as Figure 1-5 As shown, the present application provides a furnace bottom roller for a heating furnace, the furnace bottom roller comprising:

[0032] Two first fixing plates 2;

[0033] A plurality of threaded rods 201 are respectively fixedly arranged on one side of the two first fixing plates 2, and the plurality of threaded rods 201 are evenly divided into two groups, and the outer surfaces of the two groups of threaded rods 201 are movably embedded with second fixing plates 203, and the plurality of threaded rods 201 have a positioning function for the two second fixing plates 203;

[0034] Two first rods 204 are fixedly arranged on the inner walls of the two second fixed plates 203, respectively, and one side of the two first rods 204 is movably sleeved with a second rod 205, and the two second rods 205 are movable;

[0035] Two telescopic springs 206 are movably sleeved on the outer surfaces of the two first sleeve rods 204, respectively. The elastic force generated by the two telescopic springs 206 can make the two arc-shaped pressure plates 207 close to the outer surfaces of the two bearings 208;

[0036] Two arc-shaped pressing plates 207 are respectively fixedly arranged on one side of the two second sleeve rods 205, and one side of the two arc-shaped pressing plates 207 is movably provided with a bearing 208. The movability of the two arc-shaped pressing plates 207 can fix the furnace bottom roller bodies 1 of different sizes;

[0037] The plurality of threaded cylinders 202 are respectively threadedly sleeved on the outer surfaces of the plurality of threaded rods 201 , and the furnace bottom roller body 1 is fixed by rotating the plurality of threaded cylinders 202 .

[0038] like Figure 1-5 As shown, the furnace bottom roller bodies 1 are arranged inside the two bearings 208 , and the inner walls of the two first fixing plates 2 are movably arranged on the outer surfaces of the two bearings 208 , and the two first fixing plates 2 support the bottom positions of the two bearings 208 .

[0039] like Figure 1-5 As shown, a connecting platform 301 is fixedly disposed on one side of the two first fixing plates 2 , two first connecting shafts 302 are fixedly disposed inside the two connecting platforms 301 , and the two connecting platforms 301 support the two first connecting shafts 302 .

[0040] like Figure 1-5 As shown, the outer surfaces of the plurality of first connecting shafts 302 are movably sleeved with push plates 303, and one side of the plurality of pushing plates 303 is movably embedded with a second connecting shaft 304, and the plurality of pushing plates 303 have a supporting function.

[0041] like Figure 1-5 As shown, a slide 305 is fixedly provided on one side of the plurality of second connecting shafts 304, and the plurality of slides 305 are evenly divided into two groups, and a cross bar 306 is movably embedded inside the two groups of slides 305. When the furnace bottom roller body 1 is subjected to heavy pressure, the plurality of push plates 303 push the plurality of slides 305 respectively.

[0042] like Figure 1-5 As shown, one side of the plurality of slide tubes 305 is fixedly provided with a squeezing spring 307, and the inner walls of the plurality of squeezing springs 307 are movably sleeved on the outer surfaces of the two cross bars 306. When squeezed, the plurality of squeezing springs 307 will generate a reverse force, which can offset a part of the force exerted on the furnace bottom roller body 1, thereby protecting the furnace bottom roller body 1.

[0043] like Figure 1-5 As shown, bases 3 are fixedly arranged on both sides of the two cross bars 306 , and two through holes are provided on one side of the base 3 close to the two cross bars 306 . The base 3 is the installation location of the furnace bottom roller on the heating furnace.

[0044] like Figure 1-5 As shown, a plurality of positioning holes 209 are respectively opened on one side of the two second fixing plates 203 , and the outer surfaces of the plurality of threaded rods 201 are respectively movably embedded in the plurality of positioning holes 209 , so that the plurality of positioning holes 209 are easily inserted.

[0045] Working principle: When the furnace bottom roller needs to be installed, two bearings 208 are sleeved on both ends of the furnace bottom roller body 1, and then they are placed inside the two first fixed plates 2 respectively. At this time, the threaded rods 201 are respectively inserted into the multiple positioning holes 209, so that the two second fixed plates 203 are above the two first fixed plates 2, and then the multiple threaded cylinders 202 are rotated to fix the two second fixed plates 203 on the first fixed plates 2, and the two arc-shaped pressure plates 207 are on the outer surfaces of the two bearings 208. The two second sets of rods 205 can slide on the outer surfaces of the two first sets of rods 204 respectively. In the process of pressing down the two second fixed plates 203, the two arc-shaped pressure plates 207 are pressed down by the two second sets of rods 205. The elastic force generated by the two telescopic springs 206 makes the two arc-shaped pressure plates 207 close to the outer surfaces of the two bearings 208, which further improves the fixing effect of the furnace bottom roller body 1, so that the installation method of the furnace bottom roller body 1 is simple. The two arc-shaped pressure plates 207 are firm and movable, and can fix furnace bottom roller bodies 1 of different sizes. When the furnace bottom roller body 1 is under heavy pressure, the pressure is transmitted to the two first fixed plates 2 through the furnace bottom roller body 1. Because the multiple push plates 303 can rotate with the multiple first connecting shafts 302 or the multiple second connecting shafts 304 as axes, the multiple slides 305 can slide on the outer surfaces of the two cross bars 306 respectively, so that the first fixed plate 2 passes through the multiple connecting platforms 301, so that the multiple push plates 303 push the multiple slides 305 respectively, so that the multiple slides 305 squeeze the multiple squeezing springs 307. The multiple squeezing springs 307 will generate a reverse force when squeezed, which can offset part of the force exerted on the furnace bottom roller body 1, thereby protecting the furnace bottom roller body 1, preventing the furnace bottom roller body 1 from being subjected to heavy pressure for a long time, and cracking due to lack of protection function, thereby increasing the service life of the furnace bottom roller body 1.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
