Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical industrial production, and specifically discloses an automatic identification and adjustment device for the size of a steel ingot. Background Art

[0002] As one of the main raw materials in the steel rolling production line, the steel ingot needs to be placed with the small end facing the heating furnace of the rolling mill when entering the heating furnace. However, since the products placed in the steel ingot workshop are arranged in a staggered manner with large and small ends, and the hoisting and loading equipment cannot effectively control the state of the steel ingot before loading, it is necessary to manually determine the position of the large and small ends of the steel ingot after loading, and then use a crane to lift and manually rotate the steel ingot for operation, resulting in low operating efficiency throughout the process, and there are also major safety hazards in manual operation.

[0003] The invention patent with application number 2015110303452 discloses a steel ingot turning machine, including a base, a track body, a groove wheel, a spherical roller bearing, a connecting frame, a main shaft, an active bevel gear, a driven bevel gear, a transmission shaft, a spherical seat, a thrust ball bearing, a motor, an automatic aligning sliding bearing, a tray, a roller table, a support cover and a cover. Although the steel ingot turning machine disclosed in the patent can adjust the size of the steel ingot before it enters the furnace, it still requires manual judgment of the feeding status of the steel ingot. In addition, the direction of the size of the steel ingot when loading the steel ingot cannot be accurately facing the heating furnace, and a certain deviation will occur during the rotation adjustment process. Even through a 180° rotation adjustment, it is impossible to ensure that the small end of the steel ingot is accurately facing the heating furnace, and manual fine-tuning is still required. Based on this, the present application proposes an automatic identification and adjustment device for the size of the steel ingot that can effectively solve the above-mentioned technical problems. Utility Model Content

[0004] The utility model mainly provides an automatic identification and adjustment device for the large and small heads of steel ingots, so as to solve the technical problems that the existing steel ingot turning machine needs to cooperate with manual observation and active operation during operation and cannot ensure that the small head end of the steel ingot is accurately facing the heating furnace.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A device for automatically identifying and adjusting the size of a steel ingot comprises a box seat, a rotating table and a rotating table driving motor, wherein a conveying roller is arranged at the upper end of the rotating table, and laser rangefinders arranged vertically toward the conveying direction of the conveying roller are arranged on the rotating tables located on both sides of the conveying roller, the laser rangefinder is electrically connected to a control box, and the rotating table driving motor is electrically connected to the control box.

[0007] As a further setting of the above solution, the rotating table includes an upper disc disposed in the circular opening on the upper surface of the box base and a lower disc disposed inside the box base. Symmetrically arranged connecting bars are connected between the upper disc and the lower disc. The rotating table driving motor is fixedly arranged at the bottom of the inner cavity of the box base, and the output shaft of the rotating table driving motor is connected to the center of the lower disc.

[0008] As a further setting of the above solution, an induction block is arranged on the connecting bar directly below the laser rangefinder, and a proximity switch radially aligned with the induction block is arranged in the box base.

[0009] As a further setting of the above solution, a rectangular opening is formed in the upper disc, and side plates are arranged on both sides of the rectangular opening. A row of conveying rollers is rotatably arranged between the two side plates, and a notch radially aligned with the laser rangefinder is formed in the middle position of the side plates.

[0010] As a further setting of the above solution, two groups of ingot clamping and adjusting mechanisms are symmetrically arranged on the rotating table on both sides of the notch.

[0011] As a further setting of the above solution, the ingot clamping and adjusting mechanism includes two groups of guide rods penetrating through the side plates. The end of each group of guide rods extending above the conveying rollers is connected with a clamping wheel. The other ends of each group of guide rods are commonly connected with a pushing part extending below the upper disc. The lower ends of the two pushing parts are both connected with racks, and the two racks are rotationally symmetrically arranged. An adjusting motor is arranged on the lower disc between the two racks, and a gear meshing with both racks at the same time is arranged at the end of the adjusting motor.

[0012] As a further setting of the above solution, each group of guide rods has at least two, and the connecting line of the centers of the clamping wheels at the ends of the guide rods in the same group is parallel to the side surface of the ingot.

[0013] Beneficial effects:

[0014] 1. The automatic ingot large and small end identification and adjustment device disclosed by the utility model uses the distance between the two side laser rangefinders and the side surface of the ingot to judge the direction of the large and small ends of the ingot, and cooperates with the automatic rotation and adjustment of the rotating table to automatically complete the adjustment of the direction of the large and small ends of the ingot throughout the process without manual operation. This not only improves the ingot feeding efficiency into the furnace, but also avoids the risk of dropping when the ingot is lifted by the overhead crane, and has higher safety.

[0015] 2. The utility model further sets two groups of ingot clamping and adjusting mechanisms. After the automatic rotation adjustment in the large and small head directions of the ingot is completed, a corresponding group of ingot clamping and adjusting mechanisms is started to perform centering clamping adjustment on the ingot. And since the center line connection of the clamping wheels in the same group is arranged parallel to the side surface of the ingot, it can effectively eliminate the rotational offset of the ingot after clamping the ingot, ensuring that the ingot enters the furnace in the best state.

[0022] To facilitate the understanding of the utility model, the following will describe the utility model more comprehensively with reference to the relevant drawings. Several embodiments of the utility model are given in the drawings, but the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0023] Embodiment 1

[0024] Embodiment 1 discloses an automatic identification and adjustment device for the large and small heads of an ingot. Refer to the attached Figures 1 - 3 , its main structure includes a box seat 1, a rotating table 2 and a rotating table drive motor 3. Specifically, the rotating table 2 includes an upper disk 201 arranged in the circular opening on the upper surface of the box seat 1 and a lower disk 202 arranged inside the box seat 1. Then, symmetrically arranged connecting bars 203 are connected between the upper disk 201 and the lower disk 202. At the same time, the rotating table drive motor 3 is fixedly arranged at the bottom of the inner cavity of the box seat 1, and the output shaft of the rotating table drive motor 3 is connected to the center of the lower disk 202.

[0025] Refer to the attached Figure 3 and the attachedFigure 6 , a rectangular opening is formed in the upper disc 201, and side plates 205 are arranged on both sides of the rectangular opening. Then, a row of conveying rollers 4 is rotatably installed between the two side plates 205. In addition, corresponding driving components are arranged at the side ends of the conveying rollers 4, so that the conveying rollers 4 can rotate forward or backward actively for conveying the ingot 9. Two laser rangefinders 5 are arranged on the rotating platforms 2 on both sides of the conveying rollers 4, and each laser rangefinder 5 is vertically arranged towards the conveying direction of the conveying rollers 4. In addition, a notch 2051 radially aligned with the laser rangefinder 5 is formed at the middle position of the side plate 205, so that the laser rangefinder 5 can directly act on the side surface of the ingot 9 on the conveying roller 4 through the notch 2051.

[0026] In addition, the laser rangefinder 5 is electrically connected to a control box 6, so that the data measured by the laser rangefinder 5 in real time can be processed by the processing module inside the control box 6 to judge whether the large end or the small end of the ingot 9 is facing the heating furnace.

[0027] Finally, an induction block 204 is arranged on the connecting bar 203 directly below the laser rangefinder 5, and a proximity switch 7 radially aligned with the induction block 204 is arranged in the box seat 1. When the rotating platform 2 rotates and adjusts the ingot 9 by 180° under the action of the rotating platform driving motor 3, the rotating platform driving motor 3 can be timely controlled to stop by the action of the proximity switch 7 on the induction block 204, realizing precise rotation control.

[0028] During the operation of the ingot large and small end automatic identification and adjustment device disclosed in Embodiment 1, the conveying roller 4 conveys the ingot 9 above, and the laser rangefinder 5 detects the change in the distance between the side surface of the ingot and the laser rangefinder 5 in real time during the conveying process. When the ranging value continuously increases, it means that the small end of the ingot is facing the rolling mill heating furnace direction, so no adjustment action is required; while when the measured value continuously decreases, it means that the large end of the ingot is facing the rolling mill heating furnace direction, and then the control box 6 issues corresponding instructions to make the rotating platform driving motor 3. Under the driving action of the rotating platform driving motor 3, the rotating platform 2 rotates and adjusts the ingot 9 together by 180°. And it immediately stops rotating after the proximity switch 7 detects the induction block 204, realizing the precise 180° rotation and turning around of the ingot. After the turning around is completed, the ingot can be normally sent out through the conveying roller 4.

[0029] Embodiment 2

[0030] Embodiment 2 discloses an ingot large and small end automatic identification and adjustment device which is optimized and improved based on the technical solution in Embodiment 1, and the same parts as those in Embodiment 1 will not be described again.

[0031] Refer to Appendix Figure 3 、Appendix Figure 4 and Appendix Figure 5, in this Embodiment 2, two sets of ingot clamping and adjusting mechanisms 8 are also symmetrically arranged on the rotating table 2 on both sides of the notch 2051 in a mirror image manner. Specifically, each ingot clamping and adjusting mechanism 8 includes two sets of guide rods 801 penetrating through the side plate 205, and a clamping wheel 802 is connected to the end of each set of guide rods 801 extending above the conveying roller 4. Specifically, when designing, each set of guide rods 801 has at least two, and the center line connecting the clamping wheels 802 at the ends of the same set of guide rods 801 is arranged parallel to the side surface of the ingot 9.

[0032] At the other end of each set of guide rods 801, a pushing part 803 extending below the upper disc 201 is commonly connected. A rack 804 is connected to the lower end of each of the two pushing parts 803, and the two racks 804 are rotationally symmetrically arranged. Finally, an adjusting motor 805 is arranged on the lower disc 202 between the two racks 804, and a gear 806 that meshes with both of the two racks 804 is arranged at the end of the adjusting motor 805.

[0033] When the ingot size head automatic recognition and adjusting device disclosed in this Embodiment 2 detects that the small head end of the ingot 9 faces the direction of the rolling mill heating furnace, it directly starts the ingot clamping and adjusting mechanism 8 on the side close to the rolling mill heating furnace direction. Under the meshing transmission of the gear 806 with both of the two racks 804 at the same time, the clamping wheels 802 on both sides simultaneously approach the side surface of the ingot 9, and the ingot 9 is clamped in the middle. And because the center line connecting the clamping wheels 802 of the same set is arranged parallel to the side surface of the ingot 9, the offset state of the ingot 9 can be finely adjusted.

[0034] When it is found that the large head section of the ingot 9 faces the direction of the rolling mill heating furnace, first, the 180° rotation adjustment of the ingot 9 is completed through the rotating table 2, and then the other set of ingot clamping and adjusting mechanisms 8 is controlled to operate, and the offset state of the ingot 9 is also finely adjusted to ensure that the furnace charging state of the ingot 9 is in the best state.

[0035] The above has made an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
