Description

Technical Field

[0001] This utility model belongs to the technical field of large steel plate rolling and forming, specifically relating to a corrugated steel plate output device and rolling fixture. Background Technology

[0002] Currently, the manufacturing of drilling fluid circulation tanks has a huge demand for structural steel plates, especially for the main structural material of the circulation tank—corrugated steel plates, which account for 80% of the total steel plate usage. Corrugated steel plates are rolled from 8mm thick steel plates using a hydraulic rolling mill. 70% of these corrugated steel plates are at least 9 meters long, falling into the category of large steel plates. However, due to the large size of the rolled steel plates, the rolling mill faces a severe challenge during the rolling process: the excessively long unsupported section between the input end of the rolling face and the steel plate at the input end results in a 1-meter sag in the steel plate, directly hindering the smooth feeding and unloading of the steel plate.

[0003] To overcome this challenge and ensure the continuity and efficiency of steel plate rolling, existing technologies typically utilize overhead cranes at the rolling station to suspend the steel plates in the air, bringing them to the same height as the rolling mill's working surface. Even so, manual feeding of the suspended steel plates is still required when rolling each corrugated section. Furthermore, during the finished corrugated steel plate discharge stage, if... Figure 5 As shown, the corrugated steel sheet 13 has significant structural features, with its bottom surface consisting of alternating flat sections 131 and protruding sections 130. These protruding sections 130 have inverted trapezoidal cross-sections. Due to its weight and uneven structure, the entire corrugated steel sheet is prone to jamming during transport, especially at the protruding sections 130. To maintain a continuous steel sheet rolling process, hoisting equipment is often needed to move the corrugated steel sheet forward, thus maintaining a continuous rolling cycle. Clearly, this series of operations relies on crane lifting and multiple people working together for alignment, which is not only labor-intensive but also makes it difficult to ensure standardized quality in corrugated sheet production due to significant manual intervention, thereby reducing the product qualification rate.

[0004] Therefore, there is an urgent need to design a new type of output device and rolling fixture suitable for large steel plate rolling, which can effectively avoid conveying jams caused by the uneven structure of corrugated steel plates, ensure the continuity of the steel plate rolling process, achieve quality standardization of corrugated plate production, reduce manual intervention, and improve production efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned problems existing in the prior art and to provide a corrugated steel plate output device and rolling fixture. The corrugated steel plate output device uses a rotating frame and three transmission rollers to form a triangular transmission roller frame to transport corrugated steel plates. This effectively solves the technical problem of conveying jams caused by the uneven structure of corrugated steel plates, ensures the continuity of the steel plate rolling process, reduces the frequency of use of bridge cranes and manual intervention in the rolling process, and significantly improves production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] On the one hand, this utility model provides a corrugated steel plate output device, including a support frame. Multiple sets of triangular transmission roller frames for conveying corrugated steel plates are evenly distributed on the support frame. Each set of triangular transmission roller frames includes a rotating frame. The rotating frame is mounted on the support frame through bearings. Three transmission rollers are mounted on the rotating frame through bearings. The transmission rollers are distributed in an equilateral triangle on the rotating frame and are parallel to each other. The radius of the transmission rollers is greater than the protrusion height of the protrusion of the bottom end face of the corrugated steel plate.

[0008] The rotating frame includes a main shaft and two bearing plates. The main shaft is mounted on the support frame via bearings, and the bearing plates are symmetrically fixed at both ends of the main shaft and located within the support frame.

[0009] The bearing plate is provided with roller shaft holes, and the transmission roller is rotatably disposed between the two bearing plates through the roller shaft holes and bearings.

[0010] The difference between the radius of the transmission roller and the protrusion height of the protrusion on the bottom end face of the corrugated steel plate is D, and the range of D is 10mm≤D≤20mm.

[0011] The triangular transmission roller frames on the support frame are all the same height, and the distance between adjacent triangular transmission roller frames is 1000mm.

[0012] The support frame has a square structure, with the triangular transmission roller frame located between the two long sides.

[0013] The height of the triangular drive roller frame is lower than the height of the support frame.

[0014] The support plate can be any one of an equilateral triangular structure, a hexagonal structure, or a circular structure.

[0015] On the other hand, this utility model provides a corrugated steel plate rolling fixture, including a rolling mechanism, a power system, a bearing frame, a corrugated steel plate output device, and an active input mechanism for conveying flat steel. The rolling mechanism is arranged between the active input mechanism and the corrugated steel plate output device. The power system is poweredly connected to the active input mechanism. The active input mechanism is installed on the bearing frame and conveys the corrugated steel plate to the corrugated steel plate output device through the rolling mechanism.

[0016] The active input mechanism includes several conveying rollers and a tensioning wheel assembly. The several conveying rollers are evenly distributed on the support frame, and the conveying rollers at the ends are connected to the power system. The tensioning wheel assembly is installed on the support frame and is located directly above the conveying rollers at the ends.

[0017] The advantages of using this utility model are:

[0018] 1. The corrugated steel plate output device of this utility model firstly achieves mechanized conveying by forming a triangular transmission roller frame conveying corrugated steel plates through a rotating frame and three transmission rollers. This ensures the continuity of the steel plate rolling process, is conducive to the standardization of quality in corrugated plate production, and also improves the safety of conveying operations.

[0019] Secondly, the rotating frame is secured to the support frame via bearings, and three parallel drive rollers arranged in an equilateral triangle are also mounted on the rotating frame via bearings. This structural design allows the rotating frame and drive rollers to rotate smoothly together, thus ensuring the stable and efficient conveying of corrugated steel sheets.

[0020] Furthermore, by designing the radius of the transmission roller to be greater than the protrusion height of the protrusion on the bottom end of the corrugated steel plate, it is ensured that the protrusion can smoothly pass over the transmission roller without jamming, while also ensuring that the surface of the corrugated steel plate can directly contact the transmission roller, thus achieving effective transmission of the corrugated steel plate.

[0021] In summary, this utility model, by using a rotating frame and three drive rollers to form a triangular drive roller frame for conveying corrugated steel plates, effectively solves the technical problem of conveying jams caused by the uneven structure of corrugated steel plates. It also reduces the frequency of use of bridge cranes and manual intervention during the rolling process, significantly improving production efficiency and operational safety.

[0022] 2. The corrugated steel plate output device of this utility model improves the support stability of the corrugated steel plate output device by designing the rotating frame to include a main shaft and two bearing plates and fixing them symmetrically on the support frame.

[0023] 3. The corrugated steel plate output device of this utility model, through the design of roller shaft holes opened on the bearing plate and the cooperation of bearings, enables the transmission roller to rotate flexibly, which improves the adaptability of the transmission roller to different shape changes when in contact with corrugated steel plates, and ensures efficient and stable mechanized transmission.

[0024] 4. The corrugated steel plate output device of this utility model ensures that the protrusion smoothly passes over the transmission roller by limiting the difference between the radius of the transmission roller and the protrusion height of the protrusion on the bottom end face of the corrugated steel plate to 10mm≤D≤20mm, thereby avoiding jamming and excessive friction, improving the reliability of conveying, reducing wear, and extending the service life of the transmission roller.

[0025] 5. The corrugated steel plate output device of this utility model uses a triangular transmission roller frame with a height lower than the support frame to form a barrier for the corrugated steel plate during the conveying process. This not only enhances the safety of the conveying process and prevents the corrugated steel plate from shifting or jumping out during conveying, but also improves the continuity and stability of the entire conveying path.

[0026] 6. The corrugated steel plate rolling fixture in this utility model, through the coordinated design of the rolling mechanism, power system, and load-bearing frame, and the use of a corrugated steel plate output device, achieves mechanized feeding of flat steel and mechanized unloading of corrugated steel plates after they have been rolled and formed by the rolling mechanism. This not only reduces the number of workers and the frequency of crane use, achieving labor savings, but also avoids potential jamming during finished material feeding, abandoning the traditional operation method that relies solely on hoisting for cyclical movement, thus greatly improving production efficiency and operational safety.

[0027] 7. The corrugated steel plate rolling fixture in this utility model improves the adaptability to flat steel plates of different thicknesses and the stability and reliability during the conveying process through the cooperation of the tensioning wheel assembly and the end conveying roller.

[0034] 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. For ease of description, the description of the relative positional relationships of each component is based on the layout of the accompanying drawings, such as the positional relationships of front, back, top, bottom, left, and right, which are determined according to the layout direction of the accompanying drawings.

[0035] Example 1

[0036] This embodiment provides a corrugated steel sheet output device, such as... Figure 1-2 As shown, the system includes a support frame 1, on which multiple sets of triangular transmission roller frames 2 for conveying corrugated steel sheets 13 are evenly distributed. Each set of triangular transmission roller frames 2 includes a rotating frame 3, which is mounted on the support frame 1 via bearings. Three transmission rollers 4 are mounted on the rotating frame 3 via bearings. The transmission rollers 4 are arranged in an equilateral triangle on the rotating frame 3 and are parallel to each other. Thus, the triangular transmission roller frames 2, through the rotational cooperation of the rotating frame 3 and the three transmission rollers 4, form a mechanized conveying path for the corrugated steel sheet 13 at its bottom surface. It should be noted that the rotation of the rotating frame 3 and the transmission rollers 4 is not spontaneous but driven by external forces, such as the frictional force generated when the corrugated steel sheet output by the rolling mechanism contacts the top of the rotating frame 3 and the transmission rollers 4. Under the action of this external force, the rotating frame 3 and the transmission rollers 4 will rotate accordingly.

[0037] Furthermore, the radius R of the transmission roller 4 is designed to be greater than the maximum protrusion height H of the protrusion 130 on the bottom end face of the corrugated steel plate 13, so as to ensure that the protrusion 130 can smoothly pass over the transmission roller 4 without jamming, while ensuring that the surface of the corrugated steel plate 13 can directly contact the transmission roller 4 to achieve effective transmission.

[0038] In this embodiment, the corrugated steel sheet output device utilizes the principle of a triangular roller climbing stairs when conveying the corrugated steel sheet 13. Specifically, during the conveying process of the corrugated steel sheet 13, the drive roller 4 rotates due to friction to guide the flat portion 13 of the corrugated steel sheet 13 through. During this stage, the rotating frame 3 mainly plays a supporting role, maintaining relative stability and preventing significant rotation. When the side end face of the protrusion 130 of the corrugated steel sheet 13 approaches and contacts the drive roller 4, the shape of the contact surface changes. The rotating frame 3 can flexibly adjust its rotation angle to better match this change in the contact surface and achieve dynamic balance under the action of external force. If necessary, it can achieve a full 360-degree rotation to ensure that the protrusion 130 of the corrugated steel sheet 13 passes smoothly. Subsequently, the rotating frame 3 and the drive roller 4 return to their original positions, thus cyclically conveying the sheet.

[0039] like Figure 3 As shown, the rotating frame 3 includes a main shaft 30 and two bearing plates 31. The main shaft 30 is mounted on the support frame 1 (not shown in the figure) via bearings. The bearing plates 31 are symmetrically fixed at both ends of the main shaft 30 and located within the support frame 1. Meanwhile, the bearing plates 31 are provided with roller shaft holes 32. The layout and design of the roller shaft holes 32 correspond to the installation requirements of the transmission roller 4. The transmission roller 4 is rotatably mounted between the two bearing plates 31 through the roller shaft holes 32 and the bearings, ensuring the flexible rotation of the transmission roller 4 between the two bearing plates 31.

[0040] The difference between the radius R of the drive roller 4 and the maximum protrusion height of the protrusion 130 on the bottom end face of the corrugated steel plate 13 is D, where D ranges from 10mm to 20mm. By limiting this range of difference D, it is ensured that the protrusion 130 can smoothly pass over the drive roller 4 without jamming or excessive friction. This not only avoids conveying obstacles caused by size mismatch but also reduces unnecessary wear and extends the service life of the drive roller 4.

[0041] Continue to refer to Figure 1 The triangular drive roller frames 2 on the support frame 1 are installed at the same height, and the distance between adjacent triangular drive roller frames 2 is 1000mm. Furthermore, the support frame 1 has a square structure, with the triangular drive roller frames 2 located between the two long sides. By maintaining the consistent height and reasonable spacing of the triangular drive roller frames 2, the corrugated steel plate output device of this embodiment can achieve uniform support for the corrugated steel plate 13, ensuring that the corrugated steel plate maintains a stable state during transportation, thereby improving transportation efficiency and safety.

[0042] Furthermore, the height of the triangular drive roller frame 2 can be designed to be lower than the height of the support frame 1, thereby forming a barrier for the corrugated steel plate during the conveying process.

[0043] In some embodiments, the shape of the support plate 31 may also be designed as an equilateral triangle structure, a hexagonal structure, or a circular structure.

[0044] Example 2

[0045] Based on the structure of Example 1, this embodiment provides a structure for a corrugated steel plate rolling fixture.

[0046] like Figure 4 As shown, the corrugated steel plate rolling fixture in this embodiment includes a rolling mechanism 5, a power system 6, a bearing frame 7, a corrugated steel plate output device, and an active input mechanism 8 for conveying flat steel. The corrugated steel plate output device adopts the structure of the corrugated steel plate output device in Embodiment 1. The corrugated steel plate rolling fixture in this embodiment outputs the corrugated steel plate 13 through the structure of the corrugated steel plate output device in Embodiment 1.

[0047] Specifically, the rolling mechanism 5 is positioned between the active input mechanism 8 and the corrugated steel plate output device, forming a complete corrugated steel plate rolling processing link. The rolling mechanism 5 integrates two core components: the rolling die and the rolling mill. The rolling working surface of the rolling die is at the same horizontal level as the top surface of the active input mechanism 8, ensuring a smooth transition of the flat steel material from the active input mechanism 8 to the rolling mechanism 5 for rolling processing. The detailed structure of the rolling mechanism 5 and the connection methods between its components are conventional techniques in this field and will not be elaborated upon here.

[0048] Based on actual working conditions, the power system 6 is rationally configured near the active input mechanism 8 and is poweredly connected to the active input mechanism 8. The active input mechanism 8 is mounted on the load-bearing frame 7. It is responsible for receiving the power provided by the power system 6, and then processing it through the rolling mechanism 5. Subsequently, it conveys the processed corrugated steel plate 13 to the corrugated steel plate output device for further conveying processing.

[0049] Further reference Figure 4The active input mechanism 8 includes several conveying rollers 9 and a tensioning wheel assembly 10. The conveying rollers 9 are evenly distributed on the support frame 7. Preferably, the conveying rollers 9 are at the same height, and the distance between adjacent conveying rollers 9 is 1000mm. The end conveying rollers 9 are powered by the power system 6. The tensioning wheel assembly 10 is mounted on the support frame 7 and located directly above the end conveying rollers 9. The tensioning wheel assembly 10 can adjust the gap between the tensioning wheel and the end conveying rollers 9 by moving the tensioning wheel up and down to accommodate flat steel of different thicknesses. At the same time, the tensioning wheel assembly 10 can also increase the pressure on the flat steel, thereby increasing the friction between the steel plate and the conveying rollers, ensuring that the flat steel can maintain a smooth and efficient forward movement during the conveying process. The tensioning wheel assembly 10 includes core components such as a metal proximity switch and a hydraulic cylinder. Since the detailed structure of the tensioning wheel assembly 10 and the connection methods between its components are conventional techniques in this field, they will not be described in detail here.

[0050] In addition, the support frame 7 is equipped with an encoder 11 for calculating the distance between adjacent protrusions 13 on the bottom end face of the corrugated steel plate 13. The fixed position of the encoder 11 corresponds to the end conveying roller 9, and the encoder 11 is communicatively connected to the rolling mechanism 5.

[0051] The above description is only a specific embodiment of the present utility model. Any feature disclosed in this specification may be replaced by other equivalent or similar features unless otherwise specified. All features or steps in all methods or processes disclosed may be combined in any way except for mutually exclusive features and / or steps.
