Description

Technical Field

[0001] This utility model relates to the field of hot-rolled strip steel coiling guide technology, specifically a high-safety hot-rolled strip steel coiling guide device. Background Technology

[0002] The hot-rolled strip coiling guide device is used to position the hot-rolled strip coiling and facilitate the coiling process. Hot-rolled strip, also known as hot-rolled steel strip or hot plate, is a strip and plate material produced by hot rolling process.

[0003] Patent CN214391711U discloses a hot-rolled strip steel coiling guide device, including a base plate. A mounting frame is fixedly connected to the top of the base plate. A rotating shaft is rotatably connected inside the mounting frame, and a guide roller is fixedly connected to the surface of the rotating shaft. One end of the rotating shaft passes through the mounting frame and extends to one side of the mounting frame. A motor is installed at one end of the rotating shaft and is fixed to the top of the base plate. Mounting plates are fixedly connected to both sides of the inner wall of the mounting frame, and a mounting block is fixedly connected to the top of the mounting plate. A threaded rod passes through the middle of the mounting block and is threadedly connected to the mounting block. This utility model relates to the field of hot-rolled strip steel coiling guide technology. This hot-rolled strip steel coiling guide device solves the problem that existing equipment cannot effectively limit the movement of hot-rolled strip steel during coiling, leading to easy displacement and potential safety accidents.

[0004] However, the hot-rolled strip coiling guide device described above still has the following problems during use:

[0005] The left and right ends of the hot-rolled strip are limited by the position change of the threaded rod. However, the threaded rod is prone to displacement when subjected to vibration, which is not conducive to the effective limitation of the hot-rolled strip. This can cause the hot-rolled strip to deviate during the subsequent coiling process, potentially leading to safety accidents. In addition, the outside of the entire device lacks necessary protective measures. Once the equipment malfunctions or is operated incorrectly, it will pose a serious safety hazard to the workers. Therefore, this issue needs to be addressed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-safety hot-rolled strip coiling guide device, which can provide stable positioning for hot-rolled strip, while the protective measures can protect the workers.

[0007] A high-safety hot-rolled strip steel coiling guide device includes a coiling guide device body, which includes a mounting frame and a guide roller. A cylinder is fixedly connected to each side of the mounting frame facing each other. A limiting plate located on the top of the guide roller is fixedly connected to the output end of the cylinder. A guardrail is installed at the front end of the mounting frame.

[0008] Preferably, there are at least two cylinders connected between the limiting plate and its corresponding mounting bracket, and they are evenly distributed on the limiting plate.

[0009] Preferably, the limiting plate has a vertical groove on the side near the hot-rolled strip, and a cylinder is rotatably connected to the vertical groove, the width of the groove opening being smaller than the diameter of the cylinder.

[0010] Preferably, the limiting plate consists of two parts, left and right, wherein the left part is located on the left side of the cylindrical axis and the right part is located on the right side of the cylindrical axis, and the left and right parts of the limiting plate are connected by bolts.

[0011] Preferably, the guardrail includes a first guardrail tube fixedly connected to the mounting frame and a second guardrail inserted into the first guardrail tube. The first guardrail tube has a through hole, and the second guardrail has a matching groove. A spring is fixedly connected to the bottom of the groove, and a limiting rod that can slide in the groove and the through hole is fixedly connected to the other end of the spring.

[0012] Preferably, the guardrail is an arc shape facing the inward bend of the hot-rolled strip steel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This high-safety hot-rolled strip steel coiling guide device is equipped with a cylinder and a limiting plate. The cylinder controls the position of the limiting plate, allowing it to stay stably in the required position. This provides stable horizontal limiting for the hot-rolled strip steel, preventing possible deviation during subsequent coiling. The protective railing provides a barrier between the coiling guide device and the workers, protecting them in case of equipment malfunction or operational errors.

[0015] 2. This high-safety hot-rolled strip steel coiling guide device is equipped with a limiting plate consisting of two parts, left and right. The left part is located on the left side of the cylindrical axis, and the right part is located on the right side of the cylindrical axis. The left and right parts of the limiting plate are connected by bolts, so that when the cylinder is damaged, the cylinder can be easily removed from the limiting plate by removing the bolts. Similarly, this setting also facilitates the installation of the cylinder. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figure 1 As shown, a high-safety hot-rolled strip steel coiling guide device includes a coiling guide device body 1. The coiling guide device body 1 includes a mounting frame 2 and a guide roller 3. A cylinder 4 is fixedly connected to each side of the mounting frame 2 facing each other. A limiting plate 5 located on the top of the guide roller 3 is fixedly connected to the output end of the cylinder 4. A guardrail 6 is installed at the front end of the mounting frame 2.

[0024] Specifically, a cylinder 4 and a limiting plate 5 are installed. The cylinder 4 controls the position of the limiting plate 5, so that the limiting plate 5 can be stably stopped in the required position, thereby providing a stable horizontal limit for the hot-rolled strip steel, thus preventing the hot-rolled strip steel from deviating during the subsequent coiling process. A protective railing 6 is installed to provide a barrier between the main body 1 of the coiling guide device and the workers, so as to protect the workers in case of equipment failure or operational errors.

[0025] like Figure 1As shown, there are at least two cylinders 4 connected between the limiting plate 5 and its corresponding mounting bracket 2, and they are evenly distributed on the limiting plate 5.

[0026] Specifically, by setting at least two cylinders 4 and distributing them evenly on the limiting plate 5, it can be ensured that the limiting plate 5 can distribute the force evenly when under stress, thereby improving the stability of the limiting plate 5 and enabling it to better withstand the pressure and vibration of hot-rolled strip steel.

[0027] like Figure 1 and Figure 2 As shown, a vertical groove 7 is provided on the side of the limiting plate 5 near the hot-rolled strip steel, and a cylinder 8 is rotatably connected to the vertical groove 7. The width of the groove opening of the vertical groove 7 is smaller than the diameter of the cylinder 8.

[0028] Specifically, the cylinder 8 can rotate in the vertical groove 7. The rotating connection of the cylinder 8 can reduce friction with the hot-rolled strip and reduce wear. Compared with the fixed limiting method, this design can extend the service life of the limiting plate 5 and the hot-rolled strip. The groove width of the vertical groove 7 is set to be smaller than the diameter of the cylinder 8, so that the cylinder 8 cannot come out of the groove when rotating in the vertical groove 7, making the limiting of the hot-rolled strip more stable.

[0029] like Figure 1 and Figure 2 As shown, the limiting plate 5 consists of two parts, left and right. The left part is located on the left side of the axis of the cylinder 8, and the right part is located on the right side of the axis of the cylinder 8. The left and right parts of the limiting plate 5 are connected by bolts 9.

[0030] Specifically, the limiting plate 5 is composed of two parts, left and right. The left part is located on the left side of the axis of the cylinder 8, and the right part is located on the right side of the axis of the cylinder 8. The left and right parts of the limiting plate 5 are connected by bolts 9, so that when the cylinder 8 is damaged, the cylinder 8 can be easily removed from the limiting plate 5 by removing the bolts 9. Similarly, this setting also facilitates the installation of the cylinder 8.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, the guardrail 6 includes a first guardrail tube 10 fixedly connected to the mounting bracket 2 and a second guardrail 11 inserted into the first guardrail tube 10. The first guardrail tube 10 has a through hole 12, and the second guardrail 11 has a matching groove 13. A spring 14 is fixedly connected to the bottom of the groove 13, and a limiting rod 15 that can slide in the groove 13 and the through hole 12 is fixedly connected to the other end of the spring 14.

[0032] Specifically, the guardrail 6 is composed of a first guardrail tube 10 fixedly connected to the mounting frame 2 and a second guardrail 11 inserted into the first guardrail tube 10, so that the length of the guardrail 6 is adjustable, thus adapting to different working scenarios. The guardrail 6 is equipped with through holes 12, grooves 13, springs 14 and limiting rods 15, so that the length of the guardrail 6 can be easily adjusted, thereby improving work efficiency.

[0033] like Figure 1 As shown, guardrail 6 is an arc shape facing the inward bend of the hot-rolled strip steel.

[0034] Specifically, by setting the guardrail 6 to be an arc shape facing the inward bend of the hot-rolled strip, in the event of equipment failure or operational error, the guardrail 6 can continuously apply force in the opposite direction to the hot-rolled strip that has deviated from the guide roller 3, thereby avoiding excessive deviation that could cause damage to the workers.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
