[0002] Steel rolling is the process of changing the shape of steel ingots and billets between rotating rollers. The purpose of steel rolling is the same as other pressure processing. On the one hand, it is to obtain the required shape, such as steel plates, strip steel, wire rods and various steel sections; on the other hand, it is to improve the internal quality of steel. Our common automobile plates, bridge steel, boiler steel, pipeline steel, rebar, rebar, electrical silicon steel, galvanized sheet, tin plate, including train wheels are all processed through steel rolling.

[0003] Steel rolling methods can be divided into hot rolling and cold rolling according to the rolling temperature. At present, there are no protective measures on the side plates of the cold zone rolling line operation of the hot rolling layer of hot rolled steel. When personnel check the operating status of the equipment, they can only stand above the side plate for inspection, and the inside of the side plate is the high-speed rotating roller, which brings safety hazards to point inspections; during production, there are sometimes problems such as strip steel "flying" out of the cold rolling channel and laminar water splashing, which not only threatens the lives of nearby workers, but also pollutes the motor and production line. Therefore, traditional fixed guardrails are usually installed between the laminar roller and the motor, but when replacing the roller and motor, the guardrail needs to be repeatedly disassembled and installed, which increases extra workload and delays production tasks.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0027] The embodiment of the present application provides a roller conveyor edge guard plate, which solves the problem that when the existing roller conveyor and the motor are replaced, the guardrail installed between the roller conveyor and the motor needs to be repeatedly disassembled and assembled, which increases the workload and greatly affects the production efficiency.

[0028] In the related art, in the hot rolling wide strip steel production line, in order to prevent the strip from running off and the laminar water from splashing out, a side plate is generally arranged on the side of the laminar roller, so that the motor arranged on the side of the laminar roller will be blocked by the side plate, thereby preventing the strip from flying out or the laminar water from splashing onto the motor, which can protect the motor and keep the production line clean. In addition, it is safer for the inspection personnel to stand and observe the laminar roller. In general, a side plate can protect 4 motors at the same time and is fixed between the motor and the laminar roller. When there is a problem with the motor, the side plate needs to be removed and hoisted to one side by an overhead crane, and then the motor is repaired or replaced. After the motor is repaired or replaced, the side plate is installed. The removal, hoisting and installation of the side plate will consume a lot of time, which seriously affects the maintenance and replacement efficiency of the motor and the production operation efficiency.

[0029] refer to Figure 1 The roller edge guard plate provided in the embodiment of the present application includes a baffle 1 and a guard plate assembly 2. The baffle 1 is arranged on both sides of the width direction Y of the roller 100. The baffle 1 has a length extending along the length direction of the roller 100 and a height extending along the vertical direction; the guard plate assembly 2 includes a first guard plate 21 and a second guard plate 22 which are movably connected to each other. The first guard plate 21 is connected to the baffle 1, and the second guard plate 22 can rotate relative to the first guard plate 21 along the height direction Z of the baffle 1; the first guard plate 21 is used to block the gap between the roller 100 and the motor 200, and the second guard plate 22 is used to block the motor 200.

[0030] The roller conveyor 100 includes a plurality of rollers arranged in parallel, the width direction Y of the roller conveyor 100 is the length direction of each roller, and the length direction of the roller conveyor 100 is the arrangement direction of the plurality of rollers. Each roller is connected to a motor 200 .

[0031] In the embodiment of the present application, baffles 1 are arranged on both sides of the roller 100, so that the baffles 1 are located between the roller 100 and the motor 200 to prevent the strip from running off and flying out or to block the splashing of laminar water. On this basis, a protective plate assembly 2 is also arranged, wherein the protective plate assembly 2 includes a first protective plate 21 and a second protective plate 22 which are movably connected to each other. The first protective plate 21 is connected to the baffle 1, so that the first protective plate 21 is located above the gap between the roller 100 and the motor 200, and the second protective plate 22 is located above the motor 200, thereby effectively preventing laminar water from splashing onto the motor 200 and causing damage to the motor 200 and pollution of the production line. Moreover, the second protective plate 22 can rotate relative to the first protective plate 21. When the motor 200 needs to be repaired or replaced, the second protective plate 22 can be flipped over to expose the motor 200 for the staff to operate. After the staff completes the repair or replacement of the motor 200, the second protective plate 22 can be flipped over and put down. The entire process does not require the disassembly and installation of the protective plate assembly 2, which greatly improves the repair and replacement efficiency of the motor 200, thereby improving production efficiency.

[0032] It should be noted that, in order to facilitate production, the baffle 1, the first protective plate 21 and the second protective plate 22 can be produced separately, so that the production efficiency of the roller side guard can be improved. When installing the roller side guard, the baffle 1 can be installed first, and then the first protective plate 21 can be connected to the baffle 1, and finally the second protective plate 22 can be connected to the first protective plate 21. Since the baffle 1, the first protective plate 21 and the second protective plate 22 all have a certain weight, each component is installed one by one, which can reduce the difficulty of installation for the staff and save more effort. Of course, in order to improve the installation efficiency of the roller side guard, the baffle 1 can also be installed first, and then the first protective plate 21 and the second protective plate 22 can be connected and assembled in advance, and finally the assembled protective plate assembly 2 can be connected to the baffle 1 as a whole. The specific installation method can be freely selected according to the actual situation, and the embodiments of this application are not specifically limited.

[0033] For example, the baffle 1, the first protective plate 21 and the second protective plate 22 can be made of the same material, such as steel plate, iron sheet, etc. Furthermore, an anti-rust layer can be coated on the outer surface of the baffle 1, the first protective plate 21 and the second protective plate 22, so that they will not be corroded by laminar water after long-term use.

[0034] In practical applications, the length of the roller 100 is much longer than the length of a roller side guard plate, so multiple roller side guard plates can be spliced ​​in sequence to completely block the side of the roller 100 and achieve a good protective effect. Specifically, when installing the baffle 1, multiple baffles 1 can be set in close proximity in sequence, and then the protective plate assembly 2 can be installed on each baffle 1 one by one, which can not only achieve a good protective effect, but also reduce the difficulty of production and installation of the roller side guard plate. Furthermore, in order to prevent laminar water from splashing out of the gap between two adjacent baffles 1, a splicing plate can be set at the gap between two adjacent baffles 1, or an elastic seal can be set between two adjacent baffles 1, so that the gap between two adjacent baffles 1 can be blocked. Correspondingly, the same splicing plate or elastic seal is also required at the gap between two adjacent protective plate assemblies 2, so that the whole formed by splicing multiple roller side guard plates can better protect the motor 200, and effectively prevent the strip from flying out or laminar water from splashing, causing the motor 200 to be damaged.

[0035] In some embodiments, reference Figure 1 , along the width direction Y of the roller table 100, the size of the second protective plate 22 is greater than or equal to the size of the motor 200; the orthographic projection of the motor 200 on the protective plate assembly 2 is located on the second protective plate 22. In this way, it can be ensured that the second protective plate 22 is located directly above the motor 200, completely covering the motor 200, and achieving a good protective effect.

[0036] It should be noted that the orthographic projection of the motor 200 on the protective plate assembly 2 is located on the second protective plate 22, which means that the orthographic projection of the motor 200 on the protective plate assembly 2 is entirely located on the second protective plate 22, that is, the second protective plate 22 completely covers the motor 200. In this way, not only will the laminar water not splash onto the motor 200, but after the second protective plate 22 rotates relative to the first protective plate 21, the motor 200 can be completely exposed, so that the space for the staff to repair or replace the motor 200 is not limited, which is more conducive to the staff to repair or replace the motor 200, thereby improving the efficiency of the repair or replacement of the motor 200, and will not affect the production efficiency.

[0037] Specifically, the above structure can be set in a variety of different ways. For example, the connection between the first protective plate 21 and the second protective plate 22 can be located directly above the gap between the roller 100 and the motor 200. At this time, the size of the second protective plate 22 in the width direction Y of the roller 100 is larger than the size of the motor 200 in the width direction Y of the roller 100. This can ensure that the second protective plate 22 completely covers the motor 200. After the second protective plate 22 is flipped open, the motor 200 and a part of the gap between the roller 100 and the motor 200 will be exposed, so that there is more space for maintenance or replacement of the motor 200, which is beneficial for the staff to perform corresponding operations on the motor 200. The connection between the first protective plate 21 and the second protective plate 22 may also be located directly above the side of the motor 200 close to the roller 100. In this case, the size of the second protective plate 22 in the width direction Y of the roller 100 may be greater than or equal to the size of the motor 200 in the width direction Y of the roller 100. In this way, the second protective plate 22 can completely cover the motor 200, and when the second protective plate 22 is flipped open, the motor 200 can also be completely exposed, which will not affect the staff's maintenance and replacement of the motor 200.

[0038] In some embodiments, the second protective plate 22 rotates at an angle of 0°-180° relative to the first protective plate 21. In this way, after the second protective plate 22 is flipped, there will be no objects blocking the motor 200, which will not affect the maintenance or replacement of the motor 200 by the staff, thereby improving the efficiency of the maintenance or replacement of the motor 200. In addition, the second protective plate 22 can be flipped at different angles in different usage scenarios, and the usage occasions are more extensive.

[0039] In the embodiment of the present application, the first protective plate 21 is connected to the baffle 1, but there is no specific restriction on the setting angle of the first protective plate 21 and the baffle 1. Among them, the first protective plate 21 can be vertically set on both sides of the roller 100. Of course, in order to facilitate the patrol personnel to observe the roller 100 more safely, or to reduce the difficulty of installing the baffle 1, the baffle 1 can also be tilted on both sides of the roller 100, which can also play a protective role. After the first protective plate 21 and the second protective plate 22 are connected, they are in the same plane, so the first protective plate 21 can be horizontally set and connected to the baffle 1. Of course, the first protective plate 21 can also be tilted downward. At this time, it is necessary to ensure that the second protective plate 22 is located above the motor 200 when it is not flipped, and will not collide with the motor 200.

[0040] In some embodiments, reference Figure 1, the first protective plate 21 is perpendicular to the baffle 1. When the baffle 1 is vertically arranged on both sides of the roller table 100, the first protective plate 21 is arranged perpendicular to the baffle 1 so that the first protective plate 21 and the second protective plate 22 are in a horizontal state, which better prevents the laminar water from splashing onto the motor 200, protects the motor 200 from damage, and keeps the production line clean and tidy.

[0041] It should be noted that the first protective plate 21 being perpendicular to the baffle 1 means that the baffle 1 is arranged vertically and the first protective plate 21 is arranged horizontally, which does not mean that the angle between the first protective plate 21 and the baffle 1 can only be 90 degrees. It can be considered normal if an error within a certain range occurs when manually installing the baffle 1 and the first protective plate 21, resulting in the angle between the first protective plate 21 and the baffle 1 not being 90 degrees. The first protective plate 21 and the baffle 1 can be considered perpendicular to each other.

[0042] In some embodiments, reference Figure 1 and Figure 2 The guard plate assembly 2 further includes a hinge device 23, and the first guard plate 21 and the second guard plate 22 are connected by the hinge device 23. After the first guard plate 21 and the second guard plate 22 are connected, the second guard plate 22 can be flipped relative to the first guard plate 21, so that the staff can complete the maintenance or replacement of the motor 200 without disassembling the guard plate assembly 2, which greatly improves the maintenance and replacement efficiency of the motor 200.

[0043] It should be noted that, in addition to the hinge device 23, the present application may also use other rotating mechanisms, such as a shaft device or a hinge device, to connect the first protective plate 21 and the second protective plate 22. In the embodiment of the present application, the hinge device 23 is used to connect the first protective plate 21 and the second protective plate 22, which has a simple structure and reduces the difficulty and cost of installing the first protective plate 21 and the second protective plate 22.

[0044] In the embodiment of the present application, after the first protective plate 21 and the second protective plate 22 are connected, since the second protective plate 22 can be flipped relative to the first protective plate 21, when the second protective plate 22 is located directly above the motor 200, there will be a certain gap between the first protective plate 21 and the second protective plate 22. When laminar water splashes from above the baffle 1 onto the protective plate assembly 2, it is possible that water will fall onto the motor 200 through the gap between the first protective plate 21 and the second protective plate 22, thereby contaminating the motor 200 and the production line.

[0045] In some embodiments, reference Figure 1The first protective plate 21 is connected to a side surface close to the motor 200 with a side guard plate 211, and the orthographic projections of the side guard plate 211 on the protective plate assembly 2 are respectively located on the first protective plate 21 and the second protective plate 22. The side guard plate 211 can cover the gap at the connection between the first protective plate 21 and the second protective plate 22, so that the laminar water will not splash onto the motor 200 from the gap between the first protective plate 21 and the second protective plate 22, thereby enhancing the protection effect on the motor 200.

[0046] It should be noted that the edge guard plate 211 is configured as a long strip and extends along the length direction X of the baffle 1. When the second protective plate 22 is located directly above the motor 200, the edge guard plate 211 will contact the second protective plate 22, thereby blocking the gap between the first protective plate 21 and the second protective plate 22. The edge guard plate 211 can be made of the same material as the first protective plate 21 and the second protective plate 22, which can save materials and reduce costs.

[0047] In some embodiments, when the second protective plate 22 is located above the motor 200, a sealing strip is provided on a side surface of the first protective plate 21 facing the second protective plate 22 and / or a side surface of the second protective plate 22 facing the first protective plate 21, and the sealing strip is respectively in contact with the first protective plate 21 and the second protective plate 22. The provision of the sealing strip can also shield the gap between the first protective plate 21 and the second protective plate 22, so that the laminar water will not splash onto the motor 200 from the gap between the first protective plate 21 and the second protective plate 22, thereby enhancing the protection effect on the motor 200.

[0048] It should be noted that the sealing strip can be arranged on the side of the first protective plate 21 close to the second protective plate 22, or on the side of the second protective plate 22 close to the first protective plate 21, or simultaneously on the side of the first protective plate 21 close to the second protective plate 22 and the side of the second protective plate 22 close to the first protective plate 21. The sealing strip can be made of elastic sealing material, such as silicone or sealing cotton, so that when the second protective plate 22 is located above the motor 200, it can be kept on the same horizontal plane as the first protective plate 21, and the sealing strip is squeezed between the first protective plate 21 and the second protective plate 22, so that the gap between the first protective plate 21 and the second protective plate 22 can be well sealed, which effectively improves the protective effect of the protective plate assembly 2 on the motor 200.

[0049] In some embodiments, reference Figure 1-Figure 3 A plurality of reinforcing plates 3 are arranged between the baffle plate 1 and the first protective plate 21, and the plurality of reinforcing plates 3 are evenly distributed along the length direction X of the baffle plate 1. The reinforcing plates 3 can enhance the overall strength of the roller side guard plate, so that the roller side guard plate is installed more firmly and has a better blocking effect on the flying strip steel and laminar water.

[0050] In some embodiments, reference Figure 1 and Figure 2 , along the width direction Y of the roller table 100, the size of the reinforcing plate 3 is equal to the size of the first protective plate 21. In this way, it can enhance the overall strength of the roller table edge guard plate, and the reinforcing plate 3 will not affect the normal flipping action of the second protective plate 22.

[0051] It should be noted that the reinforcing plate 3 can be arranged on the side surface of the first protective plate 21 away from the motor 200, so that it is convenient for the staff to install the reinforcing plate 3. The reinforcing plate 3 is vertically arranged on the first protective plate 21 and connected to the baffle 1, which is equivalent to the baffle 1, the first protective plate 21 and the reinforcing plate 3 forming a triangular structure, thereby enhancing the installation stability and reliability of the roller side guard plate. When the reinforcing plate 3 is arranged vertically, the flip angle of the second protective plate 22 will be subject to certain limitations, but as long as the orthographic projection of the reinforcing plate 3 on the protective plate assembly 2 is all located on the first protective plate 21, the flip angle of the second protective plate 22 will be greater than or equal to 90°, which will not affect the normal exposure of the motor 200 and will not limit the staff from repairing or replacing the motor 200.

[0052] In some embodiments, reference Figure 2 A handle 4 is provided on the surface of the second protective plate 22 away from the motor 200. This allows the staff to quickly flip the second protective plate 22 for easy operation.

[0053] The working principle of the present application: the first protective plate 21 and the second protective plate 22 are movably connected, and the second protective plate 22 can rotate relative to the first protective plate 21. During normal production or process roller change, the second protective plate 22 is located directly above the motor 200 to play a daily safety protection role to prevent the strip steel from flying out or laminar water from splashing onto the motor 200; when a production failure occurs or the motor 200 needs to be replaced or repaired, the second protective plate 22 is manually flipped and lifted relative to the first protective plate 21 to expose the motor 200, making it convenient for maintenance personnel to repair or replace the motor 200, thereby achieving the effect of operating the motor 200 without removing the roller side guard plate, greatly improving the efficiency of repairing or replacing the motor 200, and thus improving production efficiency.

[0054] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
