Description

Technical Field

[0001] This application relates to the field of rebar production technology, and in particular to a steel stacking detection hammer device. Background Technology

[0002] In the production process of rebar, it is usually necessary to continuously roll through multiple stands of rolling mills to gradually process the raw materials into finished rebar that meets the standards. This production process involves multiple stages, including roughing, intermediate rolling, pre-finishing rolling and finishing rolling. Each stage is equipped with corresponding rolling mill equipment to ensure that the steel can gradually reach the required size and shape. Because the production process of rebar is complex and has high precision requirements, the rolling mill equipment on the entire production line needs to work together to ensure production efficiency and product quality.

[0003] In the production of rebar, the finishing rolling area often presents technical challenges due to the high speed and harsh working environment of the rolling mill. Particularly inside the protective shield, the confined space and extremely high temperatures make it difficult for operators to detect abnormalities such as steel blockage or scrap accumulation immediately. This not only leads to severe scrap buildup inside the protective shield and prolonged processing time, but also damages critical components such as the finishing mill rolls, increasing equipment maintenance and production costs, resulting in low production efficiency and affecting the stable operation of the entire production line. Therefore, improvements are needed. Utility Model Content

[0004] To address the difficulty in detecting steel buildup inside a finishing mill, this application provides a steel buildup detection hammer device.

[0005] The steel stacking detection hammer device provided in this application adopts the following technical solution:

[0006] A steel stacking detection hammer device includes a detection mechanism arranged on one side of a protective cover. The detection mechanism includes a detection fishing line, a hammer, and a support steel pipe. The support steel pipe is arranged outside the protective cover. The hammer is slidably connected inside the support steel pipe. One end of the detection fishing line is connected to the hammer, and the other end of the detection fishing line is connected inside the protective cover. A detection switch for detecting the position of the hammer is provided outside the support steel pipe. A detection port for detection by the detection switch is opened through the support steel pipe.

[0007] Due to the confined space and extremely high temperature, operators often struggle to detect abnormalities such as steel blockage or scrap accumulation in a timely manner. This not only leads to severe scrap buildup inside the protective cover and prolonged processing time, but also damages critical components such as the rollers of the finishing mill, increasing equipment maintenance and production costs, resulting in low production efficiency and affecting the stable operation of the entire production line. The aforementioned technical solution, including a detection mechanism composed of a detection line, a counterweight, and a support steel pipe, addresses this issue. Initially, the counterweight is suspended within the support steel pipe by the detection line and maintained in a fixed initial position. The other end of the detection line is connected inside the protective cover. The system ensures that the fishing line can transmit force and monitor the position of the counterweight. The detection switch is in an untriggered state, waiting for the position of the counterweight to change. If steel piles up inside the finishing mill, the piled-up steel will burn and break the detection fishing line. Once the detection fishing line breaks, the counterweight will no longer be pulled by the fishing line and will begin to fall freely inside the support steel pipe. During the fall, the counterweight will change its position relative to its initial position. As the counterweight falls, it will pass through the detection port opened on the support steel pipe, which will trigger the corresponding detection switch. After the detection switch is triggered, it will send a signal to the control system or alarm device, so that the operator can detect the problem in time and take appropriate measures.

[0008] By setting up a detection mechanism, the steel accumulation inside the finishing mill can be monitored in real time, ensuring that operators can detect abnormalities immediately. This effectively reduces the further deterioration of equipment failures, reduces maintenance time and costs, improves the overall service life of the equipment, avoids production interruptions and equipment damage caused by steel accumulation, and effectively improves production efficiency. At the same time, the device has a relatively simple structure, high reliability and stability, reduces the possibility of failures, lowers maintenance costs, and ensures the stable operation of the production line.

[0009] Optionally, a connection hole for the fishing line to extend through is provided on the side wall of the protective cover.

[0010] By adopting the above technical solution, the connection hole is opened through the protective cover; the connection hole provides a clear channel for the detection fishing line, allowing it to extend smoothly from inside the protective cover and connect with external components such as the counterweight, simplifying the arrangement process of the detection fishing line and reducing the installation difficulty.

[0011] Optionally, an outlet guide tube is provided on one side of the support steel pipe, and a fishing line positioning ring for detecting the positioning of the fishing line is provided on the outlet guide tube. The fishing line positioning ring is located above the support steel pipe, and the detection fishing line passes through the fishing line positioning ring.

[0012] By adopting the above technical solution, the outlet guide tube is located on one side of the support steel pipe, and the fishing line positioning ring is installed on the outlet guide tube. The setting of the fishing line positioning ring helps to position the detection fishing line and can prevent the detection fishing line from shaking or shifting in the device to a certain extent, thus ensuring the accuracy and reliability of the detection results.

[0013] Optionally, the protective cover is provided with a fishing line fixing ring inside, and one end of the detection fishing line is wrapped and fixed on the fishing line fixing ring.

[0014] By adopting the above technical solution, the fishing line fixing ring is installed and fixed inside the protective cover, and the detection fishing line is wound and fixed on the fishing line fixing ring. The setting of the fishing line fixing ring simplifies the installation process of the detection fishing line, facilitates subsequent maintenance, and can effectively reduce the shaking and deviation of the detection fishing line during the operation of the device, ensuring that the fishing line can accurately and reliably transmit force, and improving the sensitivity and accuracy of the entire detection device.

[0015] Optionally, the protective cover may also be provided with a number of fishing line connecting rings, which are arranged sequentially inside the protective cover, and the detection fishing line passes through the number of fishing line connecting rings in sequence.

[0016] By adopting the above technical solution, several fishing line connecting rings are installed sequentially inside the protective cover. The setting of several fishing line connecting rings can guide the detection fishing line to be arranged in an orderly manner according to a predetermined path inside the protective cover, effectively reducing the crossing and confusion of the detection fishing line, making the layout of the fishing line clearer and more standardized, while reducing the contact and friction between the detection fishing line and other components inside the protective cover, thereby reducing the risk of the fishing line being damaged by external factors.

[0017] Optionally, the top of the weight is provided with a fishing line anchor ring for connecting the detection fishing line, and the end of the detection fishing line away from the fishing line fixing ring is wrapped around and fixed on the fishing line anchor ring.

[0018] By adopting the above technical solution, the fishing line anchor ring is installed and fixed on the counterweight, and the counterweight is connected to the detection fishing line through the fishing line anchor ring. With the setting of the fishing line anchor ring, as a key component connecting the counterweight and the detection fishing line, the connection between the counterweight and the detection fishing line is ensured to be more firm and stable, reducing the possibility of detection errors or equipment failures caused by loose or broken connections, simplifying the connection process between the counterweight and the detection fishing line, and making the connection convenient.

[0019] Optionally, the bottom of the fishing line anchor ring is provided with a threaded part, and the top of the counterweight is provided with a threaded hole for engaging with the threaded part.

[0020] By adopting the above technical solution, the threaded part is integrally formed on the fishing line anchor ring, and the fishing line anchor ring is installed on the threaded hole of the counterweight through the threaded part; through the setting of the threaded part and the threaded hole, and the cooperation between the threaded part and the threaded hole, a tight and stable connection can be formed between the fishing line anchor ring and the counterweight, which can withstand large tensile and shear forces, ensuring that the fishing line anchor ring will not easily fall off or loosen during the steel stacking inspection process.

[0021] Optionally, the support steel pipe is provided with a channel steel for installing the detection switch.

[0022] By adopting the above technical solution, the channel steel is welded and fixed to the outside of the support steel pipe, and the detection switch is located on the channel steel. Through the setting of the channel steel, as a high-strength and high-rigidity steel, the stability of the entire support structure can be significantly enhanced, ensuring the stability and safety of the detection switch during long-term use.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] By setting up a detection mechanism, the steel accumulation inside the finishing mill can be monitored in real time, ensuring that operators can detect abnormalities at the first time, effectively reducing the further deterioration of equipment failures, reducing maintenance time and costs, improving the overall service life of the equipment, avoiding production interruptions and equipment damage caused by steel accumulation, effectively improving production efficiency. At the same time, the device has a relatively simple structure, high reliability and stability, reduces the possibility of failure, lowers maintenance costs, and ensures the stable operation of the production line.

[0025] The installation process of the detection fishing line is simplified by setting the fishing line fixing ring, which facilitates subsequent maintenance. At the same time, it can effectively reduce the shaking and deviation of the detection fishing line during the operation of the device, ensuring that the fishing line can accurately and reliably transmit force, and improving the sensitivity and accuracy of the entire detection device.

[0026] By using the fishing line anchor ring, which is a key component connecting the weight and the testing fishing line, the connection between the weight and the testing fishing line is made more secure and stable. This reduces the possibility of testing errors or equipment failures caused by loose or broken connections, simplifies the connection process between the weight and the testing fishing line, and makes the connection convenient.

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses a steel stacking detection hammer device. (Refer to...) Figure 1 The steel stacking detection hammer device includes a detection mechanism 2. In this embodiment, the detection mechanism 2 is located on one side of the protective cover 1 of the finishing mill. The detection mechanism 2 includes a detection fishing line 21, a hammer 22 and a support steel pipe 23.

[0032] Reference Figure 1 Inside the protective cover 1, fishing line fixing rings 7 and fishing line connecting rings 8 are installed and fixed. Several fishing line connecting rings 8 are distributed sequentially along the exit direction of the finishing mill. A connecting hole 5 is opened through the side wall of the protective cover 1 at the exit position of the finishing mill. One end of the detection fishing line 21 is wrapped and fixed on the fishing line fixing ring 7. At the same time, the detection fishing line 21 passes through the corresponding fishing line connecting ring 8 in sequence, and passes through the inner wall of the connecting hole 5, extending out of the outside of the protective cover 1. The fishing line fixing ring 7 simplifies the installation process of the detection fishing line 21 and facilitates subsequent maintenance. The connecting hole 5 provides a clear channel for the detection fishing line 21, allowing it to extend smoothly from inside the protective cover 1 and connect with external components such as the counterweight 22. This simplifies the arrangement process of the detection fishing line 21 and reduces the installation difficulty.

[0033] Reference Figure 1 An outlet guide pipe frame 6 is installed on one side of the support steel pipe 23. In this embodiment, the finishing mill is equipped with an outlet guide pipe. The outlet guide pipe is usually installed at the outlet position of the finishing mill, corresponding to the rolling line of the finishing mill. Its function is to guide the rolled rebar or other steel materials to be discharged smoothly, while ensuring the safety of the operators. The outlet guide pipe is arranged on the outlet guide pipe frame 6.

[0034] Reference Figure 1 A fishing line positioning ring 61 is installed and fixed on the outlet guide tube 6. The fishing line positioning ring 61 is located above the support steel pipe 23, which helps to position the detection fishing line 21 and can prevent the detection fishing line 21 from shaking or shifting in the device to a certain extent, thus ensuring the accuracy and reliability of the detection results.

[0035] Reference Figure 1 and Figure 2The support steel pipe 23 is installed on the ground, and the counterweight 22 is slidably connected inside the support steel pipe 23. In this embodiment, the diameter of the counterweight 22 is smaller than the inner diameter of the support steel pipe 23. A fishing line anchor ring 9 is installed on the top of the counterweight 22. The end of the fishing line anchor ring 9 is integrally formed with a threaded part 91. A threaded hole 10 is opened on the top of the counterweight 22, and the threaded part 91 is threadedly connected to the threaded hole 10. With the cooperation of the threaded part 91 and the threaded hole 10, a tight and stable connection can be formed between the fishing line anchor ring 9 and the counterweight 22, which can withstand a large tensile force and shear force, ensuring that the fishing line anchor ring 9 will not easily fall off or loosen during the steel stacking inspection process.

[0036] Reference Figure 1 and Figure 2 The detection fishing line 21 extends from inside the protective cover 1, passes through the fishing line positioning ring 61, and is fixed around the fishing line anchor ring 9. The fishing line anchor ring 9 is a key component connecting the weight 22 and the detection fishing line 21, ensuring a more secure and stable connection between the weight 22 and the detection fishing line 21. This reduces the possibility of detection errors or equipment failures caused by loose or broken connections, simplifies the connection process between the weight 22 and the detection fishing line 21, and makes the connection convenient.

[0037] Reference Figure 1 and Figure 2 A channel steel 11 is installed on the outside of the support steel pipe 23. A detection switch 3 is equipped on the channel steel 11. At the same time, a detection port 4 is opened through the support steel pipe 23 to cooperate with the detection switch 3. In this embodiment, the detection switch 3 is used to detect the position of the hammer 22. When the hammer 22 falls through the detection port 4 opened on the support steel pipe 23, it will trigger the detection switch 3. After the detection switch 3 is triggered, it will send a signal to the control system or alarm device.

[0038] The implementation principle of the steel stacking detection hammer device in this application embodiment is as follows: In the initial state, the hammer 22 is suspended in the support steel pipe 23 by the detection fishing line 21 and is kept in a fixed initial position. The other end of the detection fishing line 21 is connected to the inside of the protective cover 1 to ensure that the fishing line can transmit force and monitor the position of the hammer 22. The detection switch 3 is in the untriggered state, waiting for the position of the detection hammer 22 to change.

[0039] If steel piles up inside the finishing mill, the piled-up steel will burn and break the detection fishing line 21. Once the detection fishing line 21 breaks, the weight 22 will no longer be pulled by the fishing line and will begin to fall freely inside the support steel pipe 23. During the fall, the weight 22 will change its position relative to its initial position. As the weight 22 falls, it will pass through the detection port 4 opened on the support steel pipe 23, which will trigger the detection switch 3 that works with it. After the detection switch 3 is triggered, it will send a signal to the control system or alarm device, so that the operator can detect the problem in time and take corresponding measures.

[0040] By setting up detection mechanism 2, the steel accumulation inside the finishing mill can be monitored in real time, ensuring that operators can detect abnormalities at the first time, effectively reducing the further deterioration of equipment failures, reducing maintenance time and costs, improving the overall service life of the equipment, avoiding production interruptions and equipment damage caused by steel accumulation, effectively improving production efficiency. At the same time, the device has a relatively simple structure, high reliability and stability, reduces the possibility of failure, lowers maintenance costs, and ensures the stable operation of the production line.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
