Description

Technical Field

[0001] The present application relates to the technical field of cantilever rollers, and in particular to a heat-resistant and crack-free cantilever roller. Background Art

[0002] The cantilever roller is a roller-shaped device commonly used in industrial production.

[0003] At present, the Chinese patent with the existing patent publication number: CN202403526U discloses a cantilever roller. It relates to an improvement in the roller head structure of a cantilever roller on a stepping furnace. It includes a roller head and a roller shaft, the roller head sleeve is arranged outside the roller shaft, and also includes a positioning sleeve and a positioning pin; the positioning sleeve is arranged between the roller head and the roller shaft, and the positioning sleeve is fixedly connected to the roller shaft; an axial positioning pin hole is provided between the outer surface of the inner end of the positioning sleeve and the inner surface of the inner end of the roller head, and the positioning pin is provided in the positioning pin hole; so that the roller head is circumferentially fixed relative to the positioning sleeve; a step hole is provided at the edge of the inner port of the roller head, the retaining ring is provided in the step hole, and the inner surface of the retaining ring is fixedly connected to the roller shaft; so that the retaining ring is axially fixed relative to the roller shaft. The utility model effectively improves the service life of the roller head and greatly improves the reliability of the connection.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that some existing cantilever rollers are connected to the roller head and the roller body by a flat key. When the cantilever roller is running, the roller head is in a red-hot state and has a certain thermal expansion, which causes the matching clearance between the keyway and the key of the roller head to become larger. In addition, the roller head is subjected to the hard impact force of the square billet, and it is easy for the key to roll or the key to fall off, so that the roller head is easy to fall off from the roller shaft, affecting the use. Moreover, when the cantilever roller is cooled, only the roller head is cooled, and the cantilever roller as a whole is not cooled, which reduces the heat resistance of the cantilever roller and causes the cantilever roller to overheat and crack. Utility Model Content

[0005] The present application provides a heat-resistant and crack-proof cantilever roller, which improves the connection strength between the roller head and the roller body and prevents the roller head from falling off. The cooling water cools the entire cantilever roller to improve the heat resistance of the cantilever roller and further prevent the cantilever roller from overheating and cracking.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a heat-resistant and non-cracking cantilever roller, the cantilever roller comprising:

[0007] Roller head;

[0008] A connecting plate is fixedly arranged on one side of the roller head, and a support sleeve is movably arranged on one side of the connecting plate, and the support sleeve can be removed;

[0009] A plurality of fixing plates are respectively fixedly arranged on both sides of the support sleeve, and a first threaded hole is opened on one side of the plurality of fixing plates, and the plurality of first threaded holes have a fixing function for the plurality of fixing plates;

[0010] A plurality of notches are respectively provided on one side of the connecting plate, and a second threaded hole is provided inside each of the plurality of notches, wherein one of the notches matches with one of the fixing plates;

[0011] A plurality of threaded nails are respectively threadedly arranged inside the plurality of second threaded holes, and the plurality of threaded nails can rotate.

[0012] As a further improvement of the present application: the outer surface of the roller shaft and the inner wall of the support sleeve are both provided with thread lines, and the multiple fixing plates are evenly divided into two groups, and one group of the fixing plates is movably embedded in the interior of the multiple slots.

[0013] As a further improvement of the present application: a fixed end plate is fixedly provided on the inner wall of one side of the roller head, a connecting pipe is fixedly provided on one side of the fixed end plate, and the fixed end plate has a fixing effect on the connecting pipe and the roller shaft.

[0014] As a further improvement of the present application: one side of the connecting pipe is fixedly arranged on one side of the roller shaft, and a support ring is fixedly arranged on the inner wall of the connecting pipe, and the support ring fixes the water pipe.

[0015] As a further improvement of the present application: a water pipe is fixedly embedded in the inner wall of the support ring, a rotating joint is provided on one side of the water pipe, and when one end of the rotating joint rotates, the other end does not rotate.

[0016] As a further improvement of the present application: a cooling pipe is provided on one side of the rotary joint, and cooling water flows into the cooling pipe.

[0017] As a further improvement scheme of the present application: two water inlets are provided on one side of the connecting pipe close to the fixed end plate, and two water outlets are provided on the connecting pipe close to the connecting plate. Cooling water flows into the interior of the roller head through the two water inlets, thereby cooling the roller head.

[0018] As a further improvement scheme of the present application: the roller body is fixedly arranged on one side of the roller shaft, and the roller shaft has a connecting function to the roller body.

[0019] Compared with the prior art, the advantages and positive effects of this application are:

[0020] 1. In the present application, when the roller head needs to be installed, one group of fixing plates is embedded in the inside of the multiple notches, and then the multiple threaded nails are rotated to connect the support sleeve and the connecting plate together. At this time, the roller body is rotated through the thread lines inside the support sleeve and the thread lines on the outer surface of the roller shaft, so that the roller shaft and the support sleeve are threadedly connected together, thereby completing the installation of the roller head. When the roller body rotates forward, the thread lines inside the support sleeve rotate in the reverse direction. When the roller body rotates reversely, the support sleeve is flipped and another group of fixing plates is embedded in the inside of the multiple notches, so that the thread lines inside the support sleeve rotate in the forward direction. When the roller body is running, the threads between the support sleeve and the roller shaft are more tightly matched, and the roller head is more difficult to fall off, thereby improving the connection strength between the roller head and the roller body and preventing the roller head from falling off.

[0021] 2. In the present application, when cooling the roller head, cooling water flows into the inside of the water pipe through the cooling pipe, and when the roller body rotates, the rotary joint can rotate while the cooling pipe does not rotate. The cooling water reaches the inside of the connecting pipe through the water pipe, and then flows into the inside of the roller head through two water inlets, thereby cooling the roller head. The cooling water inside the roller head then flows into the inside of the connecting pipe close to the connecting plate through the two water inlets. The cooling water flows into the inside of the roller body through the roller shaft, cooling both of them, and then flows out through the side of the roller body close to the rotary joint, thereby cooling the entire cantilever roller with the cooling water, thereby improving the heat resistance of the cantilever roller and further preventing the cantilever roller from overheating and cracking.

Therefore, the present application is not limited to the specific embodiments of the following disclosure.

[0030] Embodiment 1, as Figure 1-5 As shown, the present application provides a heat-resistant and non-cracking cantilever roller, the cantilever roller comprising:

[0031] Roller head 1;

[0032] The connecting plate 2 is fixedly arranged on one side of the roller head 1, and a support sleeve 203 is movably arranged on one side of the connecting plate 2. When the support sleeve 203 and the connecting plate 2 are connected together, the installation of the roller head 1 is completed;

[0033] A plurality of fixing plates 201 are respectively fixedly disposed on both sides of the support sleeve 203, and a first threaded hole 204 is opened on one side of each of the fixing plates 201;

[0034] A plurality of notches 207 are respectively provided on one side of the connecting plate 2, and a second threaded hole 208 is provided inside each of the plurality of notches 207. The plurality of second threaded holes 208 enable the support sleeve 203 to be fixed;

[0035] The plurality of threaded screws 202 are respectively threadedly disposed inside the plurality of second threaded holes 208 , and the support sleeve 203 is fixed by rotating the plurality of threaded screws 202 .

[0036] like Figure 1-5 As shown, threads 209 are provided on the outer surface of the roller 205 and the inner wall of the support sleeve 203 , and the multiple fixing plates 201 are evenly divided into two groups, one group of fixing plates 201 is movably embedded in the inside of the multiple slots 207 , and one of the fixing plates 201 is inside the multiple slots 207 .

[0037] like Figure 1-5 As shown, a fixed end plate 3 is fixedly provided on the inner wall of one side of the roller head 1 , and a connecting pipe 301 is fixedly provided on one side of the fixed end plate 3 , through which cooling water flows out.

[0038] like Figure 1-5 As shown, one side of the connecting tube 301 is fixedly arranged on one side of the roller shaft 205, and a supporting ring 302 is fixedly arranged on the inner wall of the connecting tube 301, and the supporting ring 302 divides the interior of the connecting tube 301 into two parts.

[0039] like Figure 1-5 As shown, a water pipe 303 is fixedly embedded in the inner wall of the support ring 302 , and a rotary joint 304 is provided on one side of the water pipe 303 . When the roller body 206 rotates, the rotary joint 304 can rotate while the cooling pipe 305 does not rotate.

[0040] like Figure 1-5 As shown, a cooling pipe 305 is provided on one side of the rotary joint 304 , and cooling water flows into the interior of the water pipe 303 through the cooling pipe 305 .

[0041] like Figure 1-5 As shown, two water inlets 306 are opened on the side of the connecting pipe 301 close to the fixed end plate 3, and two water outlets 307 are opened on the side of the connecting pipe 301 close to the connecting plate 2. Cooling water flows into the interior of the connecting pipe 301 close to the connecting plate 2 through the two water outlets 307.

[0042] like Figure 1-5 As shown, the roller body 206 is fixedly arranged on one side of the roller shaft 205. When the roller body 206 rotates, it drives the roller shaft 205 to rotate, thereby making the entire cantilever roller operate.

[0043] Working principle: When the roller head 1 needs to be installed, one group of fixed plates 201 is embedded in the multiple grooves 207. At this time, multiple threaded nails 202 are rotated to connect the support sleeve 203 and the connecting plate 2. At this time, the roller body 206 is rotated through the thread lines 209 inside the support sleeve 203 and the thread lines 209 on the outer surface of the roller shaft 205, so that the roller shaft 205 and the support sleeve 203 are threadedly connected together, thereby completing the installation of the roller head 1. When the roller body 206 rotates forward, the thread lines 209 inside the support sleeve 203 rotate in the reverse direction. When the roller body 206 rotates reversely, the support sleeve 203 is flipped over and another group of fixed plates 201 is embedded in the multiple grooves 207, so that the thread lines 209 inside the support sleeve 203 rotate in the forward direction. When the roller body 206 is running, the thread fit between the support sleeve 203 and the roller shaft 205 is tighter. The roller head 1 is more difficult to fall off, and the roller head 1 is prevented from falling off. When cooling the roller head 1, the cooling water flows into the inside of the water pipe 303 through the cooling pipe 305, and when the roller body 206 rotates, the rotary joint 304 can rotate while the cooling pipe 305 does not rotate. The cooling water comes to the inside of the connecting pipe 301 through the water pipe 303, and then flows into the inside of the roller head 1 through the two water inlets 306, so as to cool the roller head 1. The cooling water inside the roller head 1 then flows into the inside of the connecting pipe 301 close to the connecting plate 2 through the two water outlets 307. The cooling water flows into the inside of the roller body 206 through the roller shaft 205, and cools both of them. Then, it flows out through the side of the roller body 206 close to the rotary joint 304, so that the cooling water cools the entire cantilever roller, improves the heat resistance of the cantilever roller, and further prevents the cantilever roller from overheating and cracking.
