Description

Technical Field

[0001] This utility model relates to the technical field of horizontal steel coil feeding equipment, and in particular to a device for real-time monitoring of horizontal coil alignment and feeding. Background Technology

[0002] In the process of overhead crane hoisting horizontal steel coils onto the production line, the steel coils are usually transported using walking beam equipment. However, the current method of loading steel coils onto the walking beam by overhead crane using a walking beam hoisting system makes it difficult to achieve proper centering. When steel coils are required to be placed parallel to the walking beam, this placement method suffers from several drawbacks. The static saddle design lacks centering identification and is susceptible to human visual error. Specifically, the center of the manually hoisted steel coil deviates from the center of the static saddle. If this deviation is too large, the steel coil's center of gravity shifts to one side when the moving beam of the walking beam lifts, causing the coil to slip and resulting in an accident. Even after the coil slips, the walking beam can still operate normally, pushing the horizontal steel coil forward, potentially colliding with other coils or equipment ahead. This affects the quality of the coil and damages the walking beam equipment. Handling such accidents is time-consuming, disrupting the continuity of walking beam transport and impacting the overall production efficiency of the unit. Even if the initial center deviation doesn't cause the coil to fall, this deviation persists on each subsequent fixed saddle during walking beam transport until the next flipping process, where the coil needs to be flipped 90 degrees. Due to the significant initial center deviation, the flipping equipment may fail to prevent a coil falling. Therefore, a real-time monitoring device for coil centering and feeding is needed to monitor the center deviation of the steel coil during feeding in real time, so as to avoid operational accidents caused by inaccurate positioning.

It has a timely safety interlock shutdown function when an abnormal state of misalignment occurs after the coil is hoisted and fed, which improves the safety and feeding efficiency of the walking beam transportation process and avoids accidents caused by steel coils rolling off due to inaccurate positioning.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0026] Reference Figures 1 to 5As shown, a real-time monitoring device for horizontal roll alignment and feeding includes a stepping beam and a hoisting trolley spanning above the stepping beam. The stepping beam includes a moving beam 1 and a stationary beam 2. The moving beam 1 is equipped with a lifting mechanism, a traversing mechanism, and a PLC control system. The PLC control system controls the lifting mechanism and the traversing mechanism to drive the moving beam 1 to perform periodic stepping movements of rising, advancing, falling, and retreating. The stationary beams 2 are distributed on both sides of the moving beam 1, and each side of the stationary beam 2 is provided with a number of fixed saddles 3 arranged at equal intervals from front to back along the advancing direction of the moving beam 1. The above-mentioned stepping beam has been disclosed in the prior art, and this utility model can improve upon the existing stepping beam.

[0027] The key point of this application is that the stepping beam also includes a centering monitoring mechanism and a joint control alarm mechanism; the centering monitoring mechanism includes several sets of laser ranging sensors 4 electrically connected to the PLC control system, each set of laser ranging sensors 4 is distributed on both sides of a fixed saddle 3, the moving beam 1 and the stationary beam 2 of the stepping beam are set below the ground, so that the outer side of the stationary beam 2 forms a ground platform 5; each set of laser ranging sensors 4 has two sensors, and each laser ranging sensor 4 is connected to the ground platform via a mounting bracket 6. 5. Fixed connection: Two laser rangefinders 4 in the same group are symmetrically distributed around the centerline of the moving beam 1 of the stepping beam, and their detection ends are positioned opposite each other. The laser rangefinders 4 in the same group monitor the distance from the two end faces of a steel coil 7 to the corresponding laser rangefinder 4. For example, the measured values ​​from the two laser rangefinders 4 to the corresponding end faces of the steel coil are left d and right d, and the distances from the two laser rangefinders 4 to the centerline of the moving beam 1 are left L and right L. These two values, left L and right L, are based on the initial installation position and are considered constant values. Therefore, the center distance of the steel coil 7... D is taken as an absolute value; the PLC control system analyzes and calculates the data left d and right d collected by the laser rangefinder 4, as well as the constant values ​​left L and right L, and calculates the difference D between the steel coil 7 and the center of the static beam saddle through the above calculation method. It compares the result with the preset value of the system's interlock alarm. If the difference does not exceed the preset value range, it means that the center deviation detection is qualified and the moving beam 1 of the stepping beam can be conveyed normally. If the difference exceeds the preset value range, the PLC control system issues an interlock command to stop the stepping beam from running.

[0028] The joint control alarm mechanism includes several sets of audible and visual alarms 8 electrically connected to the PLC control system. These alarms 8 are arranged side-by-side on one side of the stepping beam static beam 2 via an alarm bracket 9. The alarm bracket 9 has an inverted L-shaped structure. The ground platform 5 is equipped with railings 10 on both outer sides corresponding to the stepping beam static beam 2. The vertical L-shaped end of the alarm bracket 9 is fixedly connected to one side of the railing 10. Several sets of audible and visual alarms 8 are fixedly connected side-by-side at intervals to the upper surface of the horizontal L-shaped end of the alarm bracket 9. The PLC control system triggers one of the audible and visual alarms 8 according to the detection results of a set of laser ranging sensors 4. A manual emergency stop button 11 is also provided in the middle of the vertical L-shaped end of the alarm bracket 9, and the manual emergency stop button 11 is electrically connected to the PLC control system. The audible and visual alarms 8 are arranged side by side, corresponding sequentially to the positions of the fixed saddles 3 on the walking beam. When the center deviation value detected by a certain group of laser rangefinders 4 exceeds the preset value range, the corresponding group of audible and visual alarms 8 is triggered, which can quickly identify which position of the steel coil 7 has an excessive center deviation, facilitating timely handling by staff. The manual emergency stop button 11 is connected to the PLC control system and can trigger an emergency stop signal to stop the walking beam in an emergency.

[0029] The mounting bracket 6 includes a base plate 61, a support tube 62, a side baffle 63, and a cover plate 64. The bottom of the support tube 62 is welded and fixed to the base plate 61. A notch is cut at the top of the support tube 62, and the laser rangefinder sensor is installed inside the top of the support tube. The side baffle 63 has an L-shaped structure and is fixedly connected to the notch to cover it. A through hole is opened on its vertical end wall, and the detection end of the laser rangefinder sensor 4 protrudes from the through hole. The cover plate 64 is fixedly connected to the top of the support tube 62 to cover it. Each of the four corners of the base plate 61 has a bolt connection hole, and the four bolt connection holes of the base plate 61 are fixedly connected to the ground platform 5 by expansion screws. By mounting the laser rangefinder sensor 4 at a certain height using the mounting bracket 6, the detection end of the laser rangefinder sensor can be better aligned with the end face of the steel coil 7, improving measurement accuracy. The mounting bracket 6 also encloses the laser rangefinder sensor 4 internally, providing better protection and extending its service life.

[0030] A pair of anti-rolling baffles 12 are provided behind each fixed saddle 3 corresponding to the stationary beam 2 of the stepping beam. Each anti-rolling baffle 12 includes an inclined baffle 121 and several right-angled triangular support plates 122. These right-angled triangular support plates 122 are arranged parallel and spaced apart, with the right angle of each right-angled support plate 122 located at its bottom. One side of the inclined baffle 121 is welded and fixed to the hypotenuse of each right-angled support plate 122, forming an inclined surface. The hypotenuse of each anti-rolling baffle 12 faces the fixed saddle 3 in front. The right-angled side of the right-angled support plate 122 is welded and fixed to the stationary beam 2 of the stepping beam. The anti-rolling baffles 12 prevent the steel coil from accidentally rolling down and impacting the steel coil 7 in front due to operational errors or inaccurate hoisting positioning during material loading, thus preventing a series of impact accidents.

[0031] In this embodiment, both the laser rangefinder 4 and the audible and visual alarm 8 are configured in two sets. The two sets of laser rangefinder 4 are respectively installed on both sides of the two fixed saddles 3 in front of the stepping beam to monitor the first two positions in real time. Please refer to... Figure 6 As shown, the control method for the linkage control of the laser ranging sensor and the PLC control system in this utility model is as follows:

[0032] 1) After the machine hoists the steel coil onto the first fixed saddle 3 of the walking beam, the first set of laser rangefinders 4 automatically identifies and detects the distance between the end face of the first steel coil 7 and transmits the data to the PLC control system for analysis and calculation of the center deviation. The system determines whether the position of the steel coil 7 deviates from the center of the fixed saddle 3. If the result is that the position deviates from the center, the machine stops in time and the corresponding audible and visual alarm 8 is triggered. If the result is within the preset range, the system continues to control the walking beam to perform the next action and transport the steel coil 7 to the second fixed saddle 3.

[0033] 2) The laser rangefinder 4 corresponding to the second fixed saddle 3 continues to automatically detect the end face distance of the steel coil 7 using the method in step 1). If the data detected by either of the two sets of laser rangefinders 4 is unqualified, the walking beam will stop and trigger the signal of the corresponding audible and visual alarm 8 to achieve linkage control.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
