Description

Technical Field

[0001] The invention relates to the technical field of steel rolling equipment, and in particular to a hot rolling roller strip steel rapid cleaning device. Background Art

[0002] In the hot rolling production process of strip steel, strip breakage is a common accident that seriously affects production efficiency and cost. There are many reasons that may cause strip breakage during the rolling process, such as defects in the intermediate billet shape, electrical control system failure or hydraulic system failure, excessive deformation of each pass, and bursting of the working roll. When the strip breaks, a large amount of steel plates will be left on the roller table, which hinders the continuous production and needs to be cleaned up quickly. The current cleaning method is that workers use flame cutting guns to divide large steel plates into blocks, then cut out lugs on each steel plate, and then use a crane to lift it away, which takes a lot of time and reduces the output of the hot rolling line. Moreover, due to the high temperature and certain dangers of the hot rolling environment, manual cleaning is not only extremely labor-intensive, but also poses a threat to the safety of the staff. At the same time, the cleaning efficiency is low, which greatly prolongs the downtime of the production line. Summary of the invention

[0022] Reference Figure 1~Figure 5 , which is the first embodiment of the present invention, proposes a hot rolling roller strip rapid cleaning device, which is used to be arranged in a hot rolling roller 1. The hot rolling roller 1 includes a support frame 11 and a plurality of conveying rollers 12. The plurality of conveying rollers 12 are distributed on the support frame 11 in parallel and at intervals. The hot rolling roller 1 is used to convey the heated steel plate, including a support rod 2. One end of the support rod 2 is swingably arranged relative to the support frame 11. The support rod 2 has a plurality of support rods 2. A support rod 2 is arranged between two adjacent conveying rollers 12. After the support rod 2 is swung, it is used to abut or cancel the abutment with the steel plate; a first telescopic member 3 is arranged on the support frame 11, and the first telescopic member 3 is used to drive the support rod 2 to swing.

[0023] In this embodiment, a support rod 2 is installed between two adjacent conveyor rollers 12 on a support frame 11 of a hot rolling roller 1. A first telescopic member 3 is installed on the support frame 11 to ensure that it is connected to the support rod 2. When it is necessary to clean the steel plate after the strip break, the first telescopic member 3 is started to extend it, thereby driving the support rod 2 to swing around the hinge point. After the strip break occurs, the steel plate still falls on the conveyor roller 12, and the support rod 2 is swung upward by controlling the first telescopic member 3 until the support rod 2 abuts against the steel plate. At this time, the steel plate is gradually lifted up under the action of the support rod 2, so that the steel plate in the roller can be cleaned out of the roller area. When the cleaning work is completed or the support rod 2 is not needed, the first telescopic member 3 is operated again to make the support rod 2 swing in the opposite direction and return to between the conveyor rollers 12. The height of the support rod 2 is lower than the conveyor roller 12, so that the normal strip conveying operation can be restored. After the steel plate is cleaned out of the hot rolling roller 1, the operator can further collect and recycle the steel plate.

[0024] The present invention provides an effective means for cleaning steel plates after a hot rolling roller 1 breaks. By arranging a swingable support rod 2 between adjacent conveyor rollers 12 and controlling its swing using a first telescopic member 3, the steel plates scattered on the roller after the break can be accurately processed. Compared with the traditional manual cleaning method, it greatly reduces manpower input, improves cleaning efficiency, and reduces the work intensity and risk of workers in a high-temperature, dangerous hot rolling environment. The process of moving the steel plate out of the hot rolling roller 1 reduces the involvement of large-scale lifting equipment, making the operation more convenient. At the same time, the structural design is relatively simple, easy to install and maintain, and can effectively shorten the downtime of the production line due to broken belt cleaning, improve overall production efficiency, and reduce the economic losses of the enterprise caused by downtime.

[0025] Furthermore, the first telescopic member 3 is slidably arranged relative to the support frame 11, and also includes a sliding seat 4, which is slidably arranged on the support rod 2, and the telescopic end of the first telescopic member 3 is hingedly arranged on the sliding seat 4; the second telescopic member 5 is arranged on the support frame 11, and the second telescopic member 5 is used to drive the first telescopic member 3 to slide.

[0026] In this embodiment, the first telescopic member 3 is mounted on the sliding seat 4, and the sliding seat 4 can slide freely on the support rod 2. At the same time, the second telescopic member 5 is arranged on the support frame 11, and the telescopic end of the second telescopic member 5 is connected to the first telescopic member 3. First, the first telescopic member 3 is started to drive the support rod 2 to swing and abut against the steel plate for cleaning. At the same time, the second telescopic member 5 is started to push the first telescopic member 3 to slide to a suitable position along the support rod 2. Through the cooperation of the first telescopic member 3 and the second telescopic member 5, the first telescopic member 3 can swing the support rod 2 to a larger angle by extending a short distance, and the swinging stability of the support rod 2 is better. Through the arrangement of the sliding seat 4 and the second telescopic member 5, the first telescopic member 3 can be flexibly moved on the support rod 2, which helps to restore the normal operation of the hot rolling production line more quickly.

[0027] Furthermore, it also includes a baffle 6, which is swingably set at one end of the support rod 2. After the baffle 6 is swung, it is parallel or perpendicular to the support rod 2. The baffle 6 and the second telescopic member 5 are respectively located at both ends of the support rod 2.

[0028] In this embodiment, a baffle 6 is installed at one end of the support rod 2 so that the baffle 6 can swing around the connection point with the support rod 2. Under normal conditions, the baffle 6 is perpendicular to the support rod 2 to prevent the support rod 2 from swinging too far and causing the steel plate on the support rod 2 to be unable to slide to one side of the hot rolling roller 1. After the support rod 2 is swung into place, the baffle 6 swings to a position parallel to the support rod 2 so that the steel plate can slide smoothly. The design of the baffle 6 reduces the need for additional cleaning tools and improves the integration and practicality of the equipment. When dealing with complex cleaning tasks after a broken belt, the cleaning work can be completed more efficiently, further shortening the cleaning time and increasing the recovery speed of the production line. It also reduces the risk of subsequent equipment operation failures due to incomplete cleaning.

[0029] Furthermore, one end of the baffle plate 6 is parallel to the support rod 2 and extends out of the support frame 11 .

[0030] In this embodiment, when the baffle plate 6 is parallel to the support rod 2, ensure that one end of the baffle plate 6 extends out of the support frame 11. In the actual cleaning process, as the support rod 2 swings into place, the baffle plate 6 extending out of the support frame 11 can smoothly guide the steel plate to one side of the hot rolling roller table 1, and a collection device can be set on the extension line of the support rod 2 after it swings into place, so that the steel plate can smoothly slide into the collection device, which is convenient for the staff to recycle and reuse the steel plate, and improves the integrity of the overall cleaning.

[0031] Furthermore, the support frame 11 has a lifting frame 13 , the lifting frame 13 is located below the conveying roller 12 , the support rod 2 is swingably disposed on the lifting frame 13 , and the first telescopic member 3 and the second telescopic member 5 are both located on the lifting frame 13 .

[0032] In this embodiment, a lifting frame 13 is arranged inside the support frame 11, and the swing shaft of the support rod 2 is installed on the lifting frame 13, and the first telescopic member 3 and the second telescopic member 5 are also fixed on the lifting frame 13. The setting of the lifting frame 13 facilitates the height adjustment of the support rod 2 to avoid affecting the normal conveying of the steel plate by the hot rolling roller 1. When the steel plates are piled up on the hot rolling roller 1 after the strip is broken, the lifting device of the lifting frame 13 is started to make the lifting frame 13 rise, thereby driving the support rod 2, the first telescopic member 3 and the second telescopic member 5 to rise as a whole. In this way, the support rod 2 can better contact with the accumulated steel plates and perform cleaning operations when swinging. After the cleaning is completed, the lifting frame 13 is lowered to the initial position to perform normal strip conveying or other cleaning operations. The adaptability and cleaning efficiency of the equipment are improved, ensuring that the cleaning work can be carried out quickly and comprehensively in various strip breaking situations, reducing the downtime extended due to cleaning difficulties, and improving the overall operation efficiency of the production line.

[0033] Furthermore, it also includes a slide rail, which is arranged on the lifting frame 13; the translation seat 7 is slidably arranged on the slide rail, the first telescopic member 3 is arranged on the translation seat 7, and the telescopic end of the second telescopic member 5 is arranged on the translation seat 7.

[0034] In this embodiment, a slide rail is installed on the lifting frame 13, and the translation seat 7 is installed on the slide rail so that the translation seat 7 can slide freely on the slide rail. The first telescopic member 3 is fixed on the translation seat 7, and the telescopic end of the second telescopic member 5 is connected to the translation seat 7. When cleaning the broken steel plate, the second telescopic member 5 is started to push the translation seat 7 to slide on the slide rail, thereby driving the first telescopic member 3 to move. Then, the first telescopic member 3 controls the support rod 2 to swing and abut against the steel plate for cleaning. The cleaning flexibility of the cleaning equipment in the transverse direction of the roller is improved. In the process of cleaning the broken strip, the distribution of the steel plate in the transverse direction is often uneven. This design enables the support rod 2 to be adjusted in the transverse position to better adapt to this uneven distribution. Through the cooperation of the translation seat 7 and the slide rail, the first telescopic member 3 can be quickly moved to the area where the steel plate needs to be accumulated, the support of the support rod 2 to the steel plate is improved, and the stability of the entire cleaning equipment is better, which helps to quickly restore the normal operation of the hot rolling production line, and also improves the adaptability and versatility of the equipment to different broken strip situations.

[0035] Furthermore, it also includes a limit seat 8, which is arranged on the lifting frame 13 and is located near one end of the baffle 6; one end of the limit rod 9 is arranged on the baffle 6, and the other end is used to abut against the end of the limit seat 8 near the baffle 6. After the limit rod 9 extends out of the limit seat 8, the baffle 6 swings and becomes parallel to the support rod 2.

[0036] In this embodiment, a limit seat 8 is installed on one end of the lifting frame 13 close to the baffle 6, and a limit rod 9 is installed on the baffle 6. When the support rod 2 is not swung into place, the limit rod 9 abuts against the limit seat 8, and the baffle 6 cannot swing at this time. When the support rod 2 is swung into place, the limit rod 9 slides out of the end of the limit seat 8, and the baffle 6 swings under the action of the steel plate, so that the steel plate can slide smoothly along the support rod 2. Through the cooperation of the limit rod 9 and the limit seat 8, the swing of the baffle 6 can be quickly controlled without additional control, and the accuracy and consistency of the baffle 6 swinging to the parallel position each time are guaranteed. Accurate control of the swing of the baffle 6 to the parallel position is achieved. It avoids the situation where the steel plate cannot slide or damage to the equipment due to the inaccurate position of the baffle 6. The reliability and stability of the cleaning operation are improved, so that the equipment can operate more efficiently and safely when handling cleaning tasks, which helps to improve the overall cleaning quality and the service life of the equipment.

[0037] Furthermore, a return spring is included, and two ends of the return spring act on the support rod 2 and the baffle 6 respectively, so as to provide a force parallel to the support rod 2 after the baffle 6 swings.

[0038] In this embodiment, a reset spring is installed between the support rod 2 and the baffle 6. When the baffle 6 swings to a state parallel to the support rod 2 under the action of the steel plate, the reset spring will play a role after the steel plate slides down. For example, after completing the cleaning task, the external force of the steel plate on the swing of the baffle 6 is released. At this time, due to its own elastic restoring force, the reset spring will pull the baffle 6 to swing in the opposite direction around the connection point until the baffle 6 returns to the initial state perpendicular to the support rod 2. In this way, without the need for additional complex control devices, it can be ensured that the baffle 6 automatically returns to the normal position when special cleaning is not required, so as to carry out normal steel plate conveying and other cleaning operations. The reset operation of the baffle 6 is simplified and the degree of automation of the equipment is improved. During the use of the cleaning equipment, the setting of the reset spring enables the baffle 6 to automatically return to the initial position, reducing manual intervention and complex control procedures. This not only improves the convenience of operation of the equipment, but also reduces the failure rate and maintenance cost of the equipment, and improves the overall cleaning efficiency and the operation efficiency of the production line.

[0039] Furthermore, the limiting seat 8 has a limiting slope 81 at one end close to the limiting rod 9, and the limiting slope 81 is arc-shaped. The limiting rod 9 has an arc-shaped abutting portion 91 at one end close to the limiting seat 8, and the arc-shaped abutting portion 91 has the same arc as the limiting slope 81.

[0040] In this embodiment, the limiting inclined surface 81 of the limiting seat 8 near the limiting rod 9 is designed to be arc-shaped, and the arc-shaped abutting portion 91 of the limiting rod 9 near the limiting seat 8 is processed into a shape with the same arc as the limiting inclined surface 81. When the baffle 6 swings, the limiting rod 9 swings and gradually approaches the limiting seat 8. Due to the good matching of the arc-shaped abutting portion 91 and the limiting inclined surface 81, during the abutment process, the limiting rod 9 can slide smoothly along the limiting inclined surface 81, so that the baffle 6 can be smoothly swung to a position parallel to the support rod 2. The arc-shaped contact between the limiting rod 9 and the limiting inclined surface 81 can reduce collision and jamming, so that the support rod 2 can be smoothly swung into place. After the support rod 2 is in place, the limiting rod 9 slides out of the limiting inclined surface 81. At this time, the baffle 6 swings under the action of the steel plate, ensuring that the baffle 6 smoothly reaches a position parallel to the support rod 2, thereby improving the smoothness and reliability of the cleaning operation. The stability and reliability of the baffle 6 during the swinging process are improved. The matching design of the arc-shaped limiting inclined surface 81 and the arc-shaped abutting portion 91 optimizes the movement process of the baffle 6 when it swings to the parallel position, avoiding collision, jamming and other problems caused by right-angle or other shaped limiting structures. It reduces the wear and failure risk of the equipment, improves the accuracy and efficiency of the cleaning operation, helps to extend the service life of the equipment and ensure the stability of the cleaning quality.

By setting a swingable support rod 2 between adjacent conveyor rollers 12 and controlling its swing using a first telescopic member 3, the steel plates scattered on the roller after the strip is broken can be accurately processed. Compared with the traditional manual cleaning method, it greatly reduces the manpower input, improves the cleaning efficiency, and reduces the work intensity and risk of workers in a high-temperature and dangerous hot rolling environment. The process of moving the steel plate out of the hot-rolled roller 1 reduces the involvement of large-scale lifting equipment, making the operation more convenient. At the same time, the structural design is relatively simple, easy to install and maintain, and can effectively shorten the downtime of the production line due to broken strip cleaning, improve overall production efficiency, and reduce the economic losses of the enterprise caused by downtime.
