Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, in this embodiment, a detection device for prolonging the service life of a cable drum of a buggy ladle, including buggy ladle 1 and the cable drum that set up ladle 2, the cable drum is located on buggy ladle 1, set up detection plate 4 on support seat 6 of cable drum, 3 top fixed detection plates 4 on the drum dish of cable drum, drive detection plate 4 synchronous rotations when the cable drum rotates, detection plate 4 is opposite to detection switch 5, detection plate 4 triggers detection switch 5, detection switch 5 transmits signals to a counter, the counter counts the number of turns of cable drum operation. The bottom of the buggy ladle 1 is provided with a return-to-zero switch 7, the return-to-zero switch 7 is in signal connection with the counter, the return-to-zero plate 8 is arranged on the ground, when the buggy ladle 1 runs through the return-to-zero plate 8, the return-to-zero switch 7 is opposite to the return-to-zero plate 8, and the return-to-zero plate 8 triggers the return-to-zero switch 7 to realize the return-to-zero of the counter.
The distance between the detection switch 5 and the detection plate 4 is less than or equal to 15 mm; the distance between the return-to-zero switch 7 and the return-to-zero plate 8 is less than or equal to 20mm, so that accurate triggering between the detection switch 5 and the detection plate 4 and between the return-to-zero switch 7 and the return-to-zero plate 8 is ensured.
And finding out spare switching value points in the hardware configuration of the Siemens PLC, and connecting detection signals of the detection switch and the return-to-zero switch to the PLC through a cable. The signals are judged by simple logic operation by using STEP 7. Programming through Siemens STEP7, self-defining the running direction of the buggy ladle, and opening to the ladle position as + and tapping to the tapping position as-; when the buggy ladle is opened to the ladle position, the detection switch detects once, the cable drum is considered to run for 1 circle, and the counting is increased from 0 to + N (MW 1); otherwise the count is decremented. By testing the cable drum, it follows that the internal spring will exhibit a different sound when the drum is run 15 turns in the same direction. Therefore, the value of MW1 in the program is set to 10 as alarm and 13 as the stop of the buggy ladle. When the number of running turns is more than 10 or less than-10, the operation picture displays the alarm information of high tension of the spring of the cable drum; when the number of running turns is more than 13 or less than-13, the PLC system directly controls the buggy ladle to stop running. In order to improve the accuracy of the number of turns of the cable drum, a return-to-zero switch is arranged at the bottom of the buggy ladle, a return-to-zero plate is arranged on the ground, and when the return-to-zero plate triggers the return-to-zero switch, the counter is cleared.
The device is simple in structure, convenient and fast to detect, and capable of avoiding overload use of the winding drum; and the frequency of damaging the cable drum caused by misoperation of operators is reduced, and the service life of the drum is prolonged.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
