The specific dimensions adopted in this embodiment are only for illustrating the technical solution and do not limit the protection scope of the present utility model.

[0028] Such as Figures 1-5As shown in the figure, a safety protection device for a heavy plate finishing line includes a mounting plate 1, which is installed on a roller conveyor 3 used for transporting a steel plate body 2. Specifically, the mounting plate 1 is located between two adjacent groups of roller conveyors 3, and the upper surface of the mounting plate 1 is flush with the top of the conveyor rollers of the roller conveyor 3. Moreover, the two adjacent groups of roller conveyors 3 are respectively driven by a first driving motor 11 and a second driving motor 12. At least two through holes 4 are provided on the mounting plate 1. A bracket 5 is fixedly connected to the bottom of the mounting plate 1, and a hydraulic cylinder 6 is fixedly connected to the bracket 5. The output end of the hydraulic cylinder 6 is drivingly connected to a blocking column 7. A hydraulic mechanism 8 for providing kinetic energy is also provided at the connecting end of the hydraulic cylinder 6. The blocking column 7 is coaxially distributed with the through hole 4, and the blocking column 7 vertically moves up and down in the through hole 4. When the blocking column 7 rises, it can block the steel plate body 2 to prevent it from moving forward or rushing forward due to inertia after stopping. After the blocking column 7 descends, it is flush with the upper surface of the mounting plate 1, enabling the steel plate body 2 to pass through easily.

[0029] The blocking column 7 is arranged in a frustum shape with a downward resistance while blocking the steel plate body 2, thus avoiding problems such as jumping or edge lifting of the steel plate body 2 under the impact, and improving the stability and safety of the transportation of the steel plate body 2. A buffer layer 9 is sleeved outside the blocking column 7. Specifically, the blocking column 7 is made of solid metal material, and the buffer layer 9 is made of rubber material. A number of uniformly distributed anti-slip lines 10 are provided on the outside of the buffer layer 9. The buffer layer 9 and the anti-slip lines 10 cooperate to have a buffering and protective effect on the blocking column 7, further improving the stability of the transportation of the steel plate body 2.

[0030] Specifically, the blocking column 7 is detachably installed at the top of the output end of the hydraulic cylinder 6 through screws and nuts, facilitating the replacement and maintenance of the blocking column 7. Moreover, the blocking column 7 is rotatably connected to the output end of the hydraulic cylinder 6 through a bearing. By rotating the blocking column 7, the contact position between the blocking column 7 and the steel plate body 2 can be changed, thereby prolonging the service life of the device and reducing production costs.

[0031] Specifically, a buffer spring 13 is sleeved at the output end of the blocking column 7, and the buffer spring 13 is located between the bottom of the blocking column 7 and the outer cylinder of the hydraulic cylinder 6, facilitating the buffering during the lifting and lowering of the blocking column 7 and reducing the impact loss during the lifting and lowering adjustment process.

[0032] Specifically, multiple hydraulic cylinders 6 are connected. Through the hydraulic mechanism 8, the output ends of the multiple hydraulic cylinders 6 can be synchronously telescoped. The contact points between the steel plate body 2 and the multiple blocking columns 7 are basically the same, ensuring the stability of the steel plate body 2. An electromagnetic valve 14 is provided on the connecting oil path between the hydraulic cylinder 6 and the hydraulic mechanism 8. Through the electromagnetic valve 14, the size of the connecting oil path between the hydraulic cylinder 6 and the hydraulic mechanism 8 can be controlled, thereby controlling the lifting efficiency of the blocking column 7 to improve the reaction ability and avoid the problem that the output end of the hydraulic cylinder 6 fails to extend in time under sudden conditions, resulting in the failure to support the steel plate body 2 at the bottom of the steel plate body 2.

[0033] Specifically, a suspension beam plate 15 is hoisted directly above the mounting plate 1. A camera 16 and a proximity sensor 17 are installed at the bottom of the suspension beam plate 15. The camera 16 is used to observe the distribution of the steel plate body 2 at the mounting plate 1 part, and the proximity sensor 17 is used to sense the distance between the end of the steel plate body 2 from the front end of the mounting plate 1 and the steel plate body 2.

[0034] The protection device further includes a processor 18. An A / D converter and a D / A converter are respectively provided at the input end and the output end of the processor 18. The camera 16 and the proximity sensor 17 are both electrically connected to the A / D converter. The hydraulic mechanism 8, the electromagnetic valve 14, the first drive motor 11, and the second drive motor 12 are all electrically connected to the D / A converter. The first drive motor 11 and the second drive motor 12 are interlocked and controlled through the processor 18. Specifically, in the finished product inspection area, before personnel perform roller grinding or dimension rechecking in the working area, first control the second drive motor 12 to turn off. At this time, the first drive motor 11 interlocked with the second drive motor 12 also triggers a shutdown command. And in order to achieve precise control of the subsequent position of the steel plate body 2, after the first drive motor 11 triggers the shutdown command, according to the sensing signals and feedback of the camera 16 and the proximity sensor 17, the signals are fed back to the processor 18 and compared with the set value. First, decelerate until the end of the steel plate body 2 abuts against the blocking column 7 and then the first drive motor 11 stops. At this time, the steel plate body 2 is accurately positioned at one side of the blocking column 7.

[0035] The protection device further includes an indicating mechanism composed of an indicating red light 19 and an indicating green light 20. The indicating red light 19 and the indicating green light 20 are both electrically connected to the D / A converter. When the whole machine is shut down for maintenance, after the first drive motor 11 and the second drive motor 12 stop, the indicating red light 19 lights up to give a prompt. At this time, a buzzer warning can be cooperated. After maintenance, and when the first drive motor 11 and the second drive motor 12 start, the whole machine enters the working state, and the indicating green light 20 lights up for indication.

[0036] Working principle:

[0037] The steel plate body 2 is continuously transported by multiple roller conveyors 3, and there is a gap between adjacent steel plate bodies 2. After the steel plate body 2 after sizing trimming enters the finished product inspection area, the second drive motor 12 is controlled to shut down. At the same time, the hydraulic mechanism 8 is controlled to supply oil and boost pressure to the hydraulic cylinder 6, so that when the blocking column 7 rises, a blocking wall can be formed on the advancing route of the subsequent steel plate body 2. At this time, the first drive motor 11 interlocked with the second drive motor 12 also triggers a shutdown command. After the first drive motor 11 triggers the shutdown command, according to the sensing signals and feedback of the camera 16 and the proximity sensor 17, the signals are fed back to the processor 18 and compared with the set value. First, deceleration is performed until the first drive motor 11 stops after the end of the steel plate body 2 abuts against the blocking column 7. At this time, the steel plate body 2 is accurately positioned on one side of the blocking column 7. After the first drive motor 11 and the second drive motor 12 stop, the indicating red light 19 lights up to prompt. The finished product inspection personnel enter the working area to perform roller grinding or dimension recheck, improvement; after the previous steel plate body 2 or equipment maintenance is completed, the blocking column 7 descends, and the upper surface of the mounting plate 1 is flush, so that the steel plate body 2 can pass through easily. The first drive motor 11 and the second drive motor 12 are started, and the whole machine enters the working state, and the indicating green light 20 lights up for indication.

[0038] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
