Abstract
Description
Technical Field
[0001] This application relates to the field of steel rolling auxiliary equipment technology, and in particular to a guide structure between cooling bed input plates. Background Technology
[0002] A cooling bed is used to effectively cool rolled steel. It consists of three main parts: a feeding device, a walking-beam cooling bed body, and a discharging device and output roller conveyor. During operation, the rolled products are conveyed into the cooling bed body via the roller conveyor, and then the moving rack of the cooling bed gradually moves the workpieces arranged on the cooling bed body to the top of the cooling bed, achieving the desired cooling effect.
[0003] The feeding device consists of an input roller conveyor and a tilting skirt device, while the cooling bed body includes a straightening plate. The transition surface between the straightening plate and the input roller conveyor is an arc surface, referred to as the transition arc surface. During operation, after the steel section enters the input roller conveyor, the tilting skirt lifts the steel section, causing it to slide onto the inclined surface of the straightening plate and thus enter the cooling bed body for cooling. During this process, the flanges of the steel section slide along the transition arc surface between the straightening plate and the input roller conveyor. This relative sliding between the transition arc surface and the steel section flanges can create scratches on the flange surface, affecting product quality.
[0004] The above information is provided as background information only to aid in understanding this application and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this application. Utility Model Content
[0005] This application provides a guide structure between input plates of a cooling bed and a cooling bed. By setting the guide structure, the problem of scratches on the surface of the steel profile caused by the transition surface between the straightening plate and the input roller in the current cooling bed is solved, which affects the product quality.
[0006] In a first aspect, embodiments of this application provide a guide structure between cooling bed input group plates, comprising:
[0007] The system includes an input roller conveyor for receiving steel sections, a tilting skirt for lifting the steel sections entering the cooling bed, and a guide structure connected to the input roller conveyor for guiding the steel sections parallel to the direction of the input roller conveyor and assisting the input roller conveyor in receiving the steel sections. Simultaneously, it also provides guidance perpendicular to the direction of the input roller conveyor, assisting the tilting skirt in guiding the steel sections into the cooling bed.
[0008] In one feasible implementation, the cooling bed body includes multiple straightening plates, which are arranged perpendicular to and parallel to the input roller conveyor. There are gaps between adjacent straightening plates, and moving racks or guide structures are installed in the multiple gaps.
[0009] In one feasible implementation, the guide structure includes a rotating shaft and a guide wheel. One end of the rotating shaft is connected to the input roller conveyor, the guide wheel is fitted onto the circumferential surface of the rotating shaft, and the other end of the rotating shaft is provided with an anti-detachment structure.
[0010] In one feasible implementation, the rotating shaft is equipped with a self-lubricating bushing, and the guide wheel is fitted onto the circumferential surface of the self-lubricating bushing.
[0011] In one feasible implementation, the guide structure further includes a mounting base connected to the input roller conveyor, and the rotating shaft connected to the mounting base.
[0012] In one feasible implementation, the mounting base further includes a retaining plate. The mounting base is a horizontally oriented "door"-shaped structure. The mounting base has a mounting hole. The end of the rotating shaft away from the anti-detachment structure has an insertion hole. After the end of the rotating shaft away from the anti-detachment structure passes through the mounting hole, the retaining plate is inserted into the insertion hole to fix the rotating shaft.
[0013] In one possible implementation, the side of the guide wheel includes a plane and a curved surface, the plane being close to and perpendicular to the input roller conveyor, and the curved surface connecting to the side of the plane away from the input roller conveyor and curving towards the direction of the straightening plate.
[0014] In one feasible implementation, the radius of curvature of the surface is 180mm to 220mm.
[0015] In one feasible implementation, the guide wheel is made of ductile iron.
[0016] The cooling bed input group plate guiding structure and cooling bed provided in this application include an input roller conveyor, a tilting skirt, and a guiding structure. The guiding structure provides guidance parallel to the direction of the input roller conveyor, assisting the input roller conveyor in receiving the steel profiles. Simultaneously, it provides guidance perpendicular to the direction of the input roller conveyor, assisting the tilting skirt in guiding the steel profiles into the cooling bed body. The guiding structure achieves guidance parallel and perpendicular to the direction of the input roller conveyor, effectively assisting the input roller conveyor in receiving the steel profiles and ensuring that the steel profiles can accurately and efficiently enter the cooling bed body. Furthermore, the guiding structure includes guide wheels, replacing the method of contact and relative sliding between the steel profile flanges and the transition curved surface of the straightening plate, avoiding numerous scratches on the steel profile flanges and improving product quality.

Detailed Implementation
[0028] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.
[0029] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0030] Reference Figure 1 and Figure 2 As shown, Figure 1 This is a top view of the existing cooling bed input structure. Figure 2 This is a side sectional view of the existing cooling bed input structure.
[0031] In the steel rolling process, the steel sections processed by the rolling mill are cut into specific lengths by the rolling shearing machine and then cooled on a cooling bed. These steel sections include, but are not limited to, H-beams, channel steel, angle steel, and square steel.
[0032] The cooling bed includes an input roller conveyor 1, through which the steel profiles to be cooled enter. The input roller conveyor 1 includes multiple parallel rollers 11 to facilitate the movement of the steel profiles. The centerline of the input roller conveyor 1 forms an angle θ with the centerline of the rollers 11, with the angle θ being 15°~35°, reducing the possibility of deviation and jumping of the steel profiles during transport. The transition surface between the straightening plate 31 in the cooling bed body 3 and the input roller conveyor 1 is an arc surface, hereinafter referred to as the transition arc surface 33. (Refer to...) Figure 3 As shown, Figure 3 This is a schematic diagram of the tilting skirt action in the input end of an existing cooling bed. During cooling, after the steel section enters the input roller conveyor 1, the tilting skirt 2 lifts the steel section, causing the flanges of the steel section to slide along the transition arc surface 33 between the straightening plate 31 and the input roller conveyor 1, and enter the cooling bed body 3 to achieve cooling. During this process, the relative sliding between the transition arc surface 33 and the steel section flanges can cause scratches on the surface of the steel section flanges, affecting product quality. This application sets up a guide structure, using guide wheels in the guide structure to replace the method of the steel section flanges contacting and sliding relative to the transition arc surface of the straightening plate, thus avoiding a large number of scratches on the steel section flanges and improving product quality.
[0033] The following description, in conjunction with the accompanying drawings, details the guiding structure between the input plates of the cooling bed and the specific structure of the cooling bed provided in this application.
[0034] Reference Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the guide structure arrangement in the cooling bed provided in this embodiment. Figure 5 This is a schematic diagram of the guide structure and the steel profile in the cooling bed provided in this application embodiment. The guide structure between the input group plates of the cooling bed provided in this application includes an input roller conveyor 1, a tilting skirt 2, and a guide structure 5. The input roller conveyor 1 serves as the input end for receiving the steel profile, and the tilting skirt 2 is used to lift the steel profile entering the cooling bed and tilt it at a certain angle so that the steel profile enters the cooling bed body 3.
[0035] The cooling bed body 3 includes multiple straightening plates 31. The extension direction of the straightening plates 31 is perpendicular to the direction of the input roller conveyor 1, and the multiple straightening plates 31 are arranged in parallel. There are gaps 32 between adjacent straightening plates 31. The parallel arrangement of the straightening plates 31 forms multiple gaps 32. In some gaps 32, a moving rack 4 is installed. The moving rack 4 completes stepping under the drive of the drive device, so that the steel can be conveyed gradually and continuously on the cooling bed. In other gaps 32 where the moving rack 4 is not installed, a guide structure 5 is set. The guide structure 5 is connected to the input roller conveyor 1 to achieve guidance parallel to the direction of the input roller conveyor 1, assisting the input roller conveyor 1 in receiving the steel. At the same time, it achieves guidance perpendicular to the direction of the input roller conveyor 1, assisting the flipping skirt 2 in allowing the steel to enter the cooling bed body 3.
[0036] Reference Figure 6 As shown, Figure 6 This is a cross-sectional view of a guide structure in a cooling bed provided in an embodiment of this application. The guide structure 5 includes a rotating shaft 51 and a guide wheel 52. One end of the rotating shaft 51 is connected to the input roller conveyor 1, and the guide wheel 52 is fitted onto the circumferential surface of the rotating shaft 51. The other end of the rotating shaft 51 is provided with an anti-detachment structure 511. As an example, the rotating shaft 51 is mounted on one end of the input roller conveyor 1 with an external thread, and a threaded hole is also provided in the input roller conveyor 1. The rotating shaft 51 is screwed onto the input roller conveyor 1 for easy assembly, disassembly, and maintenance.
[0037] Reference Figure 7 As shown, Figure 7 This is a cross-sectional view of another guide structure in a cooling bed provided in this application embodiment. In some embodiments, the guide structure 5 further includes a mounting base 53, which is connected to the input roller conveyor 1, and the rotating shaft 51 is connected to the mounting base 53. The connection between the mounting base 53 and the input roller conveyor 1 can be welded or connected by multiple bolts, thereby enhancing the strength of the structure and the stability of the device.
[0038] Reference Figure 8 As shown, Figure 8This is a cross-sectional view of another cooling bed guide structure provided in this application embodiment. In some embodiments, the mounting base 53 further includes a clamping plate 531. The mounting base 53 is a horizontally placed "door"-shaped structure. The mounting base 53 has a mounting hole 532. The end of the rotating shaft 51 away from the anti-detachment structure 511 has an insertion hole 513. After the end of the rotating shaft 51 away from the anti-detachment structure 511 passes through the mounting hole 532, the clamping plate 531 is inserted into the insertion hole 513 to fix the rotating shaft 51. The "door"-shaped structure of the mounting base 53 fixes both ends of the rotating shaft 51. The structure is simple, easy to operate, and enhances the firmness and convenience of installation. In some embodiments, the rotating shaft 51 is also equipped with a self-lubricating bushing 512. The guide wheel 52 is fitted on the circumference of the self-lubricating bushing 512. The self-lubricating bushing 512 makes the rotation of the guide wheel 52 smoother. Furthermore, the side surface of the guide wheel 52 includes a flat surface 521 and a curved surface 522. The flat surface 521 is close to and perpendicular to the input roller conveyor 1. The curved surface 522 connects to the side of the flat surface 521 away from the input roller conveyor 1 and bends towards the straightening plate 31. The radius of curvature of the curved surface 522 is 180mm to 220mm. For example, in this embodiment, the radius of curvature of the curved surface 522 is 200mm.
[0039] In some embodiments, the guide wheel 52 is made of ductile iron. Ductile iron has good mechanical properties and wear resistance, which allows the guide wheel 52 to maintain good shape and performance when subjected to the weight and friction of the steel profile for a long time. It is not easy to wear or deform, thereby extending the service life of the guide wheel and improving its support and guiding ability for the steel profile.
[0040] The cooling bed input plate guide structure provided in this application, by setting up a guide structure, utilizes the rolling of guide wheels to replace the direct contact and relative sliding between the steel profile flanges and the transition curved surface of the straightening plate. This effectively avoids a large number of scratches generated on the steel profile flanges during the cooling process, thereby significantly improving the surface quality and overall quality of the product. The guide structure design adopts a connection method between the mounting base and the input roller conveyor, enhancing the strength of the structure and the stability of the device, and also making the installation and disassembly of the guide structure more convenient, facilitating subsequent maintenance and repair work. Furthermore, the design of the guide wheels combines flat and curved surfaces. The flat surface is close to and perpendicular to the input roller conveyor, while the curved surface connects to the side of the flat surface away from the input roller conveyor and bends towards the straightening plate. The flat surface allows the guide wheels to better guide the steel profiles into the cooling bed body, reducing friction and resistance. The curved surface ensures that the steel profile flanges make line contact with the guide structure during the rotation of the flipping skirt plate, reducing the contact area and avoiding a large number of scratches.
[0041] In summary, the cooling bed input group plate guide structure exhibits significant beneficial effects in improving product quality, enhancing structural stability and convenience, optimizing guiding effect, improving rotation smoothness, and providing flexible installation methods.
