Description

Technical Field

[0001] This application relates to the field of metallurgical technology, and in particular to a ribbed roller and billet conveying device for conveying steel billets. Background Technology

[0002] The information provided in this section is for the purpose of generally presenting the background of this disclosure. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this disclosure.

[0003] During the production and conveying of steel billets, the conveyor rollers are exposed to high temperatures for extended periods. Without timely and effective cooling, a large amount of heat accumulates on the roller's surface and inside, causing the roller material to deform, soften, or even melt, thus shortening the roller's service life. Cooling reduces the roller temperature, maintains its material properties and structural stability, and extends the conveyor roller's lifespan. Currently, steel plants primarily use spray cooling and internal water circulation cooling methods to cool the steel billet conveyor rollers.

[0004] In some applications with limited space, it is difficult to arrange complex cooling medium pipelines and spray devices. In some equipment upgrade and renovation scenarios, the existing cooling water volume of the plant is insufficient to meet the new water volume requirements for newly added billet conveying rollers. When traditional billet conveying rollers cannot be cooled by liquid media, their service life is greatly shortened, which also affects product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a ribbed roller and a billet conveying device for billet conveying, thereby solving the problem that the cooling methods for billet conveying rollers in existing technologies are complex and costly.

[0006] The above-mentioned objectives of this application are mainly achieved through the following technical solutions:

[0007] On one hand, this application provides a ribbed roller for conveying steel billets, the ribbed roller comprising:

[0008] The roller body has a first opening and a second opening at its axial end, and a first through space extending along the axial direction of the roller body is provided between the first opening and the second opening.

[0009] The support member has two sets and is fixedly connected to the first opening and the second opening of the roller body respectively. The two sets of support members are used to fixally connect the drive shaft and the support shaft respectively, so that the drive shaft drives the roller body to rotate. Each set of support members is provided with multiple second through spaces that can communicate with the first through space, so that when the airflow flows through the first through space and the second through space, it exchanges heat with the roller body and the support member.

[0010] In an optional embodiment, the support member includes a plurality of ribs, and a second through space is formed between adjacent ribs. The ribs connect the roller body and the drive shaft, and the roller body and the support shaft.

[0011] In an optional embodiment, the plurality of ribs are arranged at uniform intervals along the circumference.

[0012] In an optional embodiment, one side of the rib is welded to the roller body, and the other side is welded to the drive shaft or the support shaft.

[0013] In an optional embodiment, the inner wall of the roller body is provided with a stepped portion for positioning the support member.

[0014] In an optional embodiment, the outer peripheral surface of the roller body is provided with a wing plate.

[0015] In an optional embodiment, two wing plates are provided and are arranged at axial intervals along the roller body.

[0016] On the one hand, this application also provides a billet conveying device, which includes a drive shaft, a support shaft, a drive component, and a rib roller as described above. The roller body is arranged between the drive shaft and the support shaft, and two sets of the support components are respectively fixedly connected to the drive shaft and the support shaft. The drive component is connected to and drives the drive shaft to rotate.

[0017] In an optional embodiment, a detachable connection is provided between the drive component and the transmission shaft.

[0018] G2BJ24115631-2K1 quick-connect coupling.

[0019] In an optional embodiment, the drive shaft and the support shaft are fixed by supports, and the drive shaft, the support shaft and the roller body are arranged coaxially.

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

[0021] The ribbed roller of this application includes a roller body and supporting members. The roller body has a first opening and a second opening at its axial end, and a first through space extending axially from the first opening to the second opening is provided between the first opening and the second opening. Two sets of supporting members are provided and fixedly connected to the first opening and the second opening of the roller body, respectively. The two sets of supporting members are used to fixably connect a drive shaft and a support shaft, so that the drive shaft drives the roller body to rotate. Each set of supporting members has multiple second through spaces that can communicate with the first through space, so that when airflow passes through the first through space and the second through space, it exchanges heat with the roller body. In actual operation, the supporting members are reliably connected to the drive shaft and the support shaft. The roller body is supported on the shaft for conveying operations. High-temperature steel billets are conveyed through the rib rollers and undergo heat exchange with them during contact. The rib rollers absorb heat and rise in temperature. The support and the roller body also exchange heat to a certain extent. The first through space inside the roller body and multiple second through spaces on the support are connected, allowing air to flow through the first and second through spaces, contacting and lowering the roller body and support, and carrying away heat. This achieves a uniform cooling effect, solving the problem of not being able to install water cooling mechanisms due to limited space or insufficient water supply in the factory. It also reduces the cost of retrofitting and installing cooling equipment. Furthermore, the roller body does not require external supporting pipelines, making maintenance and replacement more convenient and quick, and better adapting to a fast and continuous production rhythm.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0027] like Figure 1 , Figure 2 As shown, Figure 1 A schematic diagram of the billet conveying device is provided for the embodiments of this application. Figure 2 A cross-sectional view at the roller body 100 is provided for an embodiment of this application. In one aspect, this application provides a ribbed roller for conveying steel billet 406, the ribbed roller including a roller body 100 and a support member 200, wherein:

[0028] The roller body 100 is provided with a first opening 101 and a second opening 102 at its axial end, and a first through space 103 extending along the axial direction of the roller body 100 is provided between the first opening 101 and the second opening 102.

[0029] like Figure 1 , Figure 2 As shown, the support member 200 is provided in two sets and is fixedly connected to the first opening 101 and the second opening 102 of the roller body 100 respectively. The two sets of support members 200 are used to fixally connect the drive shaft 401 and the support shaft 402 respectively, so that the drive shaft 401 drives the roller body 100 to rotate. Each set of support members 200 is provided with a plurality of second through spaces 202 that can communicate with the first through space 103, so that when the airflow flows through the first through space 103 and the second through space 202, the airflow exchanges heat with the roller body 100 and the support member 200 and carries away the heat.

[0030] In an optional embodiment, the working principle of the ribbed roller in this application is as follows: the ribbed roller includes a roller body 100 and a support member 200. The roller body 100 has a first opening 101 and a second opening 102 at its axial end, and a first through space 103 extending axially from the roller body 100 is provided between the first opening 101 and the second opening 102. Two sets of support members 200 are provided and are respectively fixedly connected to the first opening 101 and the second opening 102 of the roller body 100. The two sets of support members 200 are used to fixably connect the drive shaft 401 and the support shaft 402, so that the drive shaft 401 drives the roller body 100 to rotate. Each set of support members 200 is provided with a plurality of second through spaces 202 that can communicate with the first through space 103, so that when the airflow flows through the first through space 103 and the second through space 202, it exchanges heat with the roller body 100. During actual operation, the support member 200 is reliably connected to the drive shaft 401 and the support shaft 402, and supports the roller body 100 for conveying operations. The high-temperature steel billet 406 is conveyed through the rib roller and undergoes heat exchange with the rib roller during contact. The rib roller absorbs heat and rises in temperature. The support member 200 and the roller body 100 undergo a certain degree of heat exchange. The first through space 103 in the roller body 100 and the multiple second through spaces 202 on the support member 200 are connected, so that when the air flows through the first through space 103 and the second through spaces 202, it contacts and lowers the roller body 100 and the support member 200, and carries away the heat, thereby achieving a uniform cooling effect. This solves the problem of not being able to install a water cooling mechanism due to limited space or insufficient water supply in the factory, reduces the cost of retrofitting and installing cooling equipment, and the roller body 100 does not require external supporting pipelines, making maintenance and replacement more convenient and quick, and better adapting to the fast and continuous production rhythm.

[0031] like Figure 1 , Figure 2 As shown, in an optional embodiment, the support member 200 includes a plurality of ribs 201, and a second through space 202 is formed between adjacent ribs 201. The ribs 201 are connected between the roller body 100 and the drive shaft 401, and between the roller body 100 and the support shaft 402.

[0032] The circumferential arrangement of multiple ribs 201 not only stably connects the roller body 100, but also forms the installation space for the drive shaft 401 and the support shaft 402. The adjacent ribs 201 are arranged at intervals to form a second through space 202. While maintaining reliable connection and support, the space ratio of the second through space 202 is increased, thereby improving the cooling effect.

[0033] like Figure 1 , Figure 2As shown, in an optional embodiment, the plurality of ribs 201 are arranged at uniform intervals along the circumference, which not only maintains uniform support but also improves the uniformity of the second through space 202.

[0034] In an optional embodiment, one side of the rib plate 201 is welded and fixed to the roller body 100, and the other side is welded and fixed to the drive shaft 401 or the support shaft 402.

[0035] like Figure 1 , Figure 2 As shown, in an optional embodiment, the inner wall of the roller body 100 is provided with a step portion 104 for positioning the two sets of support members 200. When assembling the support members 200, the step portion 104 provides a restriction on the assembly position of the support members 200, so that the support members 200 can be installed at the target position more easily and quickly, while also improving the connection reliability of the support members 200.

[0036] like Figure 1 , Figure 2 As shown, in an optional embodiment, a wing plate 301 is provided on the outer peripheral surface of the roller body 100. The wing plate 301 forms a barrier on the roller body 100 to restrict the steel billet 406 during the conveying process, so as to avoid the steel billet 406 from deviating during the conveying process and improve the conveying reliability.

[0037] In an optional embodiment, two wing plates 301 are provided and arranged at intervals along the axial direction of the roller body 100. The two wing plates 301 are respectively positioned on both sides of the billet 406 during the conveying process, further improving the reliability of the billet 406 during the conveying process.

[0038] like Figure 1 , Figure 2 As shown, in one aspect, this application also provides a billet conveying device, which includes a drive shaft 401, a support shaft 402, a drive member 403, and a rib roller as described above. The roller body 100 is arranged between the drive shaft 401 and the support shaft 402, and two sets of support members 200 are respectively fixedly connected to the drive shaft 401 and the support shaft 402. The drive member 403 is connected to and drives the drive shaft 401 to rotate.

[0039] In an optional embodiment, a coupling 404 is provided between the drive member 403 and the transmission shaft 401 for detachable connection.

[0040] like Figure 1 , Figure 2As shown, in an optional embodiment, the drive shaft 401 and the support shaft 402 are respectively fixed by the support 405, and the drive shaft 401, the support shaft 402, and the roller body 100 are arranged coaxially to maintain the roller body 100 during the driving operation.
