Description

Technical Field

[0001] This utility model relates to the technical field of steelmaking conveying equipment, and more specifically to a hot conveying roller structure. Background Technology

[0002] In steelmaking, steel billets are transported to the next process (returning to the rolling mill for reheating) via a row of spaced hot conveyor rollers. These rollers are subjected to high temperatures and impact loads during operation. Existing hot conveyor rollers are prone to deformation of the roller assembly, leading to uneven load breakage of the coupling, which in turn prevents the normal transport of steel billets, requiring shutdown for maintenance and severely impacting production efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hot conveyor roller structure. This invention has a simple structure, is easy to implement, can withstand high temperature and impact load, has good stability and high reliability, long service life, and reduces maintenance costs.

[0004] The purpose of this utility model is achieved through the following technical solution: a hot conveying roller structure, including a motor and multiple hot conveying roller mechanisms. The output end of the motor is provided with a first double drive sprocket. The multiple hot conveying roller mechanisms include a roller body assembly and a bearing seat. The roller body assembly includes a roller shaft, a roller sleeve, a positioning ring, and a flange ring. Both ends of the roller shaft are set on the bearing seat. One end of the roller shaft passes through the bearing seat and is provided with a second double drive sprocket. An external thread is provided on the outer surface of this end. A locking nut is provided on the external thread. The roller sleeve, positioning ring, and flange ring are all set on the roller shaft between two bearing seats. The positioning rings are spaced on the roller shaft, and one of the positioning rings is provided with an exhaust hole. The roller sleeve is fitted around the positioning ring. The flange ring is set at one end of the roller sleeve and forms an outer protruding edge. The second double drive sprocket is connected to the first double drive sprocket through a chain, and the multiple second double drive sprockets are connected to each other through chains.

[0005] In one preferred embodiment, the bearing housing includes a shaft seat, a self-aligning roller bearing, and an end cover. The outer ring of the self-aligning roller bearing is connected to the shaft seat, and the inner ring of the self-aligning roller bearing is connected to the roller shaft. The end cover is located on both axial sides of the self-aligning roller bearing and is mounted on the shaft seat. The end cover is used to position the outer ring of the self-aligning roller bearing.

[0006] In one preferred embodiment, the end cap is provided with a through hole for the roller shaft to pass through, and the through hole is provided with a labyrinth seal structure.

[0007] In one preferred embodiment, the end cap is further provided with a lubrication port, which is directly opposite the roller of the self-aligning roller bearing.

[0008] In one preferred embodiment, a transmission box is provided between the first dual-drive sprocket and the motor output end.

[0009] The beneficial effects of this utility model are as follows: This utility model adopts an integral structure roller shaft with high structural strength. At the same time, the opening of ventilation holes can effectively prevent the internal pressure inside the space formed by the roller shaft, roller sleeve and positioning ring from increasing due to heat, which would cause deformation of the roller assembly. Furthermore, the use of a dual drive sprocket and chain to achieve transmission connection makes the overall transmission more stable. It can continue to transport normally even when the deformation of the roller assembly is small or large, reducing maintenance frequency and maintenance costs, thus achieving cost reduction and efficiency improvement.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0018] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0020] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0021] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0022] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] See Figures 1-3 This utility model provides a technical solution: a hot conveying roller structure, including a motor 1 and multiple hot conveying roller mechanisms 2. The output end of the motor 1 is provided with a first double drive sprocket 11. The multiple hot conveying roller mechanisms 2 include roller body assemblies 3 and bearing seats 4. The roller body assembly 3 includes a roller shaft 31, a roller sleeve 32, a positioning ring 33, and a flange ring 34. Both ends of the roller shaft 31 are disposed on the bearing seats 4. One end of the roller shaft 31 passes through the bearing seat 4 and is provided with a second double drive sprocket 35. The outer surface of this end is provided with an external thread. A locking nut 7 is provided on the roller. The roller sleeve 32, positioning ring 33 and flange ring 34 are all provided on the roller shaft 31 between the two bearing seats 4. The positioning rings 33 are spaced on the roller shaft 31, and one of the positioning rings 33 is provided with an exhaust hole 331. The roller sleeve 32 is sleeved on the periphery of the positioning ring 33. The flange ring 34 is provided at one end of the roller sleeve 32 and forms a raised edge on the outside. The second double drive sprocket 35 is connected to the first double drive sprocket 11 through the chain 5, and multiple second double drive sprockets 35 are connected in pairs through the chain 5. This utility model adopts an integral structure roller shaft 31 with high structural strength. At the same time, it has ventilation holes, which can effectively prevent the internal pressure inside the space formed by roller shaft 31, roller sleeve 32 and positioning ring 33 from increasing due to heat, thus preventing deformation of roller assembly 3. Furthermore, the transmission connection is achieved by using a dual drive sprocket with chain 5, which makes the overall transmission more stable. It can continue to transport normally even when the deformation of roller assembly 3 is small or large, reducing maintenance frequency and maintenance costs, thus achieving cost reduction and efficiency improvement.

[0025] Preferably, the bearing housing 4 includes a shaft seat 41, a self-aligning roller bearing 42, and an end cover 43. The outer ring of the self-aligning roller bearing 42 is connected to the shaft seat 41, and the inner ring of the self-aligning roller bearing 42 is connected to the roller shaft 31. The end cover 43 is disposed on both axial sides of the self-aligning roller bearing 42 and installed on the shaft seat 41, and the end cover 43 is used to position the outer ring of the self-aligning roller bearing 42.

[0026] Preferably, the end cap 43 is provided with a through hole for the roller shaft 31 to pass through, and a labyrinth sealing structure 6 is provided at the through hole. This improves the dustproof effect, ensures the long-term stable operation of the self-aligning roller bearing 42, and extends its service life.

[0027] Preferably, the end cap 43 is further provided with a lubrication inlet 431, which is directly opposite the roller of the self-aligning roller bearing 42. This facilitates directional and precise application of lubricant, ensuring that the lubricant accurately enters the roller of the self-aligning roller bearing 42 and guarantees the long-term stable operation of the self-aligning roller bearing 42.

[0028] Preferably, a transmission box 8 is provided between the first dual-drive sprocket 11 and the output end of the motor 1. This can isolate and mitigate noise and vibration generated by power transmission, thereby protecting the stable operation of the machine, and can also adjust the speed according to transportation needs.
