Description

Technical Field

[0001] This utility model relates to the technical field of steel plate straightening equipment, and in particular to a special facility for monitoring the tilting of steel plates after straightening. Background Technology

[0002] In steel production, hot-rolled steel plates often exhibit a curling-up phenomenon during straightening. This is caused by factors such as improper straightener roll gap settings, uneven steel plate temperature, or material differences. When the steel plate passes the straightening rolls, its end bends upwards, forming a curled-up end. If this curled-up steel plate continues to be conveyed along the production line, it will cause severe mechanical impact and damage to subsequent equipment. Traditional straightening operations rely mainly on visual observation by operators to judge the condition of the steel plate. However, due to the harsh production environment and the high speed of steel plate movement, manual monitoring often suffers from problems such as delayed response and inaccurate judgment.

[0003] Currently, there are some steel plate warping detection devices on the market, mainly employing grating detection or contact detection methods. While grating detection devices can achieve non-contact detection, they are easily affected by environmental factors such as dust and water mist, leading to a high false alarm rate. Existing contact detection devices have relatively simple structures, typically providing only simple switching signals, unable to accurately determine the severity of warping and hindering graded control. Furthermore, these devices often only provide emergency shutdown measures upon detecting warping, lacking a gradual response mechanism, which can easily cause unnecessary production interruptions.

[0004] Existing technologies also suffer from difficulties in resetting equipment. Many detection devices require manual intervention to reset after triggering, increasing the workload and safety risks for operators. Furthermore, the mechanical structures of detection devices often lack effective buffering mechanisms, making them susceptible to mechanical impact damage during long-term use, affecting the reliability and lifespan of the equipment. Therefore, there is a need to develop a dedicated monitoring facility capable of accurately detecting the degree of steel plate warping, implementing graded response control, and possessing automatic reset functionality. Utility Model Content

[0005] The purpose of this invention is to provide a special facility for monitoring the warping of steel plates after straightening, so as to solve the technical problems in the prior art, such as low accuracy of warping detection, lack of graded response control, and difficulty in equipment reset.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A specialized facility for monitoring the warping of steel plates after straightening includes a straightening machine and a monitoring component. The straightening machine is installed on the side wall of the outlet end of the straightening machine. The monitoring component includes a base installed on the side wall of the outlet end of the straightening machine. A trigger structure is provided at the bottom of the base. The trigger structure includes brackets symmetrically arranged at the bottom of the base. The brackets are laterally rotatable and have the same rotating shaft inserted into them. Gears are sleeved at both ends of the rotating shaft. Racks are laterally meshed at the bottom of the gears. Sliding sleeves are slidably sleeved at both ends of the racks. The sliding sleeves are fixed to the bottom of the base. A common baffle is laterally arranged at the end of the rack away from the straightening machine. Mounting brackets are symmetrically arranged at both ends of the baffle. Three photoelectric sensors are arranged on the side of the mounting brackets near the baffle. A detection arm is vertically arranged at the bottom of the rotating shaft.

[0008] The above technical solution utilizes gear and rack transmission and a three-stage photoelectric sensor to achieve precise graded detection and automatic protection control of steel plate warping.

[0009] Preferably, a mounting plate is also provided vertically at the bottom of the base, and the same tension spring is provided between the side wall of the mounting plate and the side wall of the shielding rod.

[0010] The above technical solutions provide an automatic reset function, allowing the system to return to its initial monitoring state without external power, thus improving the automation level of the equipment.

[0011] Preferably, the mounting plate has dampers installed laterally at both ends on the side near the shielding bar.

[0012] The above technical solutions aim to control the reset speed, avoid shock oscillations caused by rapid reset, and improve system stability and detection accuracy.

[0013] Furthermore, the straightening machine has a steel plate inside, with a raised head at the end of the steel plate. The end of the raised head slides against the outer circumference of the detection arm.

[0014] The above technical solutions enable direct mechanical contact detection of steel plate warping, resulting in rapid response and high detection reliability.

[0015] Furthermore, the photoelectric sensor is divided into a receiver and a transmitter, and the receiver and transmitter form a group for use together. It is divided into three groups and is equally spaced.

[0016] Through the above technical solution, three sets of equidistant through-beam photoelectric sensors achieve precise quantitative classification of the degree of tilting, avoiding false detection.

[0017] Preferably, an audible and visual alarm is provided on the top of the base.

[0018] The above technical solutions provide operators with intuitive audible and visual early warning information, facilitating timely detection of problems and the implementation of countermeasures.

[0019] Preferably, the base sidewall is equipped with a controller, which is electrically connected to the straightening machine, photoelectric sensor and audible and visual alarm.

[0020] The above technical solutions enable closed-loop control with the straightening machine, automatically executing corresponding protective actions based on the degree of head tilt, thereby improving production safety.

[0021] The beneficial effects of this utility model are as follows:

[0022] The rotational motion of the detection arm is converted into the linear motion of the blocking rod through a gear and rack transmission mechanism, achieving motion amplification and precise transmission. Combined with three sets of equidistantly distributed photoelectric sensors, it can accurately detect steel plate warping of varying degrees, enabling graded monitoring and control. A tension spring provides continuous reset force, allowing the system to automatically reset to its initial monitoring state after the warping disappears, eliminating the need for manual intervention and improving automation and efficiency. A damper acts as a buffer during system reset, preventing shock oscillations caused by rapid reset, protecting mechanical components from damage, extending equipment lifespan, and improving detection accuracy and system stability. The mechanical contact detection method, with the detection arm in direct contact with the warped steel plate, provides a fast response time, is unaffected by environmental factors such as dust and water mist, and offers high reliability. The controller implements graded response control based on different levels of photoelectric sensor signals, avoiding unnecessary shutdowns due to minor warping while ensuring emergency protection in cases of severe warping, improving production efficiency and equipment safety. An audible and visual alarm provides operators with intuitive warning information, facilitating timely problem detection and appropriate measures, enhancing the user-friendliness and safety of human-machine interaction.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

Detailed Implementation

[0029] 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.

[0030] Example 1

[0031] Reference Figures 1 to 4 This utility model provides a special facility for monitoring the tilting of steel plates after straightening, including a straightening machine 1 and a monitoring component 2 installed on the side wall of the outlet end of the straightening machine 1.

[0032] The base 201 is fixed to the outlet side wall of the straightener 1 by bolts, and the bottom of the base 201 is provided with a trigger structure. The trigger structure includes a bracket 202 symmetrically arranged at the bottom of the base 201. The bracket 202 has bearing mounting holes, and the bearing is installed in the bracket 202 to provide support for the rotating shaft 203.

[0033] A rotating shaft 203 is laterally rotatable and inserted into a bracket 202. Gears 204 are fitted at both ends of the rotating shaft 203. The gears 204 are involute spur gears and are fixed to the rotating shaft 203 by a key connection. A rack 205 is laterally meshed at the bottom of each gear 204. The rack 205 and the gear 204 form a rack and pinion transmission pair, converting rotational motion into linear motion.

[0034] Both ends of the rack 205 are slidably fitted with sliding sleeves 206, which provide guidance and support for the rack 205. The sliding sleeves 206 are fixed to the bottom of the base 201. The end of the rack 205 away from the straightener 1 is provided with the same blocking rod 207, which is fixedly connected to the rack 205 and moves with the linear movement of the rack 205.

[0035] The shielding rod 207 has symmetrical mounting brackets 208 at both ends, and each mounting bracket 208 has three photoelectric sensors 209 on the side near the shielding rod 207. The photoelectric sensors 209 are divided into a receiving end and a transmitting end, and the receiving end and the transmitting end form a group for use together. They are divided into three groups and are evenly distributed.

[0036] A detection arm 6 is vertically mounted at the bottom of the rotating shaft 203, and the detection arm 6 is bolted to the rotating shaft 203. A steel plate 3 is provided inside the straightening machine 1, and the end of the steel plate 3 is a raised head 31, the end of which slides against the outer circumferential surface of the detection arm 6.

[0037] The base 201 is equipped with an audible and visual alarm 8 at the top and a controller 7 on the side wall of the base 201. The controller 7 is electrically connected to the straightening machine 1, the photoelectric sensor 209 and the audible and visual alarm 8.

[0038] Work process

[0039] When the steel plate 3 tilts upwards after passing through the straightening machine 1, the tilted head 31 will contact and push the detection arm 6. After being subjected to force, the detection arm 6 drives the rotating shaft 203 to rotate, and the gears 204 at both ends of the rotating shaft 203 rotate synchronously. The gears 204 drive the rack 205 to make linear motion, and the rack 205 pushes the stop bar 207 to move.

[0040] As the blocking bar 207 moves, it sequentially blocks three sets of photoelectric sensors 209. When the first set of photoelectric sensors is blocked, the controller 7 receives a signal and activates the audible and visual alarm 8 to issue a warning; when the second set of photoelectric sensors is blocked, the controller 7 sends a control signal to adjust the straightening machine 1; when the third set of photoelectric sensors is blocked, the controller 7 immediately sends a stop signal, and the straightening machine 1 and related equipment stop operating immediately.

[0041] Once the raised edge of the steel plate disappears, the detection arm 6 loses its thrust, and the entire system returns to its initial position under the influence of gravity. The photoelectric sensor 209 resumes normal light transmission, and the system re-enters the monitoring state.

[0042] Example 2

[0043] Based on Embodiment 1, a mounting plate 9 is also vertically provided at the bottom of the base 201, and the mounting plate 9 is fixed to the bottom of the base 201 by bolts. The same tension spring 4 is provided between the side wall of the mounting plate 9 and the side wall of the baffle rod 207, one end of the tension spring 4 is connected to the mounting plate 9, and the other end is connected to the baffle rod 207.

[0044] The tension spring 4 serves as a reset mechanism in the system. When the detection arm 6 is subjected to the pushing force of the steel plate's upward tilt, the stop rod 207 moves the tension spring, which stores elastic potential energy. When the tilt disappears, the tension spring 4 contracts, generating tension that drives the stop rod 207 back to its initial position, thus achieving automatic system reset.

[0045] Example 3

[0046] Based on Embodiment 2, dampers 5 are laterally provided at both ends of the mounting plate 9 near the baffle rod 207. One end of the damper 5 is connected to the mounting plate 9, and the other end is connected to the baffle rod 207.

[0047] The damper 5 acts as a buffer during the system reset process. When the tilting motion disappears and the stop bar 207 begins to reset under the force of the tension spring 4, the damper 5 reduces the impact force during the reset process, allowing the detection arm 6 to slowly reset to its initial position. This avoids oscillations and impacts caused by excessively rapid system reset, improving system stability and detection accuracy, and extending the equipment's service life.

[0048] Installation and usage instructions

[0049] During installation, first fix the base 201 at a suitable position on the side wall of the outlet end of the straightener 1, ensuring that the detection arm 6 can make normal contact with the steel plate warp head 31. Then, install each component in sequence according to the assembly drawing requirements, and adjust the position of the photoelectric sensor 209 to ensure that its optical axis is correctly aligned.

[0050] After powering on, debug the system, checking whether the movement of each component is normal, whether the photoelectric sensor signals are accurate, and whether the control system responds promptly. Once debugging is complete, the system can be put into normal use.

[0051] During use, the system automatically monitors for steel plate warping without requiring manual intervention. Regular inspection and maintenance of the equipment ensures long-term stable operation of the system.

[0052] Through the above specific implementation methods, this utility model can effectively monitor the warping of steel plates after straightening, take timely protective measures, avoid equipment damage, and ensure production safety.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
