[0002] The existing Chinese patent application CN214211758U discloses "a cooling bed material transport roller". In order to solve the problem of extremely large lubricating oil consumption caused by the roller transporting steel with a temperature of nearly 900°C, the patent provides oil injection holes in the vertical rollers to continuously supply lubricating oil to the vertical rollers, effectively reducing the labor intensity of workers, increasing the service life of the vertical rollers, and avoiding the low efficiency caused by manual oil injection one by one in the past.
[0003] Based on the above-mentioned public patent, since the temperature of the steel plate transported by the loading roller of the cooling bed is very high, if the roller continues to run after the steel plate is in place, steel sticking will occur over time, and the operator needs to operate the cooling bed and grinding table area, the operation volume is large, and after the steel plate is in place, it can only be viewed by monitoring, and there are no other prompt signals. Therefore, when the operator is operating other processes, he cannot check the steel plate in time, which may easily cause the roller to run for a long time and cause steel sticking, affecting the production quality.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example
[0022] like Figure 1-2 As shown, the utility model provides an interlocking structure for the alarm of the loading roller of a cooling bed, comprising a conveying device 1 for conveying steel plates, a detection component 3 for detecting whether the steel plate is in place on the conveying device 1, an alarm component 6 for prompting a detection signal of the detection component 3, and a remote PLC host 4 for controlling the detection component 3 and the alarm component 6. The detection component 3 and the alarm component 6 are respectively communicatively connected to the remote PLC host 4, and the PLC host 4 is electrically connected to the conveying device 1, and is used to control the advancement or stop of the conveying device 1 by accessing the forward interlocking signal.
[0023] In this embodiment, the detection component 3 is a photoelectric sensor, and the signal output end of the photoelectric sensor is connected to the signal input end of the remote PLC host 4. The conveying device 1 includes a loading roller 2, and the photoelectric sensor is arranged at the end of the loading roller 2. The photoelectric sensor is located between the two single rollers in the loading roller 2, and the photoelectric sensor detects whether the steel plate is in place in the gap between the two single rollers. Specifically, the photoelectric sensor is a device that converts optical signals into electrical signals. Its application range is relatively wide, and the devices used are well known to those skilled in the art. They are not elaborated in detail in this article. When installing the photoelectric sensor, the installation position needs to be measured in advance so that the photoelectric sensor can irradiate the steel plate in the gap between the two single rollers, so as to meet the requirement that the steel plate can be detected in place after being installed at the end of the loading roller 2.
[0024] In this embodiment, an operation console 5 is provided on one side of the conveying device 1, and an alarm component 6 is installed on the surface of the operation console 5. The PLC host 4 is connected to the operation console 5 through a DP cable, and the output signal end of the PLC host 4 is connected to the input signal end of the alarm component 6. The alarm component 6 is a buzzer. Specifically, the PLC host 4 is connected to the roller forward interlock signal, and is also connected to the operation console 5 site through DP communication. The output signal is connected to the buzzer. After the steel plate is transported to the position, the photoelectric sensor detects the signal, the roller interlock cannot move forward, and the buzzer sounds at the same time, reminding the operator to load the material to the cooling bed in time to avoid the problem of steel plate sticking to the steel plate for a long time. In addition, the alarm component 6 is an alarm light, and the buzzer can be replaced with an alarm light. When the alarm light is on, it means that an alarm signal has occurred, which is also used to remind the operator.
[0025] In this embodiment, the operation console 5 is provided with a display screen, a start switch and a plurality of buttons.
[0026] The working principle and use process of the utility model are as follows: by arranging a photoelectric sensor at the end of the loading roller 2, when the steel plate is conveyed, the steel plate can block and cover the photoelectric sensor, and then the photoelectric sensor can judge whether there is an obstacle when automatically emitting and receiving the light source, so that the photoelectric sensor can detect the arrival of the steel plate, and then after detecting that the steel plate is conveyed in place, the photoelectric sensor sends a signal to make its PLC host 4 control the loading roller 2 to stop moving in time, and synchronously transmit the signal to the buzzer, so that the buzzer sounds when the photoelectric sensor has a signal, reminding the operator to load the material to the cooling bed in time to operate and process the steel plate, so as to avoid the problem of steel sticking when the steel plate is under long-term use, and the buzzer stops reminding after there is no signal from the photoelectric sensor for conveying the steel plate.
