It should be noted that, springs are fixedly installed at the upper ends of the two sides of the probe sensor support plate 12, mounting seats are installed at the two ends of the measuring machine body 11 through fixing screws and threads, a connecting spring is movably installed on the mounting seats, the two ends of the extending and retracting crank arm 2 are movably installed on the mounting seats at the two ends of the measuring machine body 11 through the connecting spring, and a measuring probe is movably installed at the bottom of the measuring machine body 11.
The working principle is as follows: when the measuring machine body runs from the socket to the socket for thickness measurement:
firstly, the PLC system controls the axial guide wheel to move towards the socket at a medium speed at a constant speed. When the first laser range finder detects the cast tube, the axial guide wheel reduces the speed to low speed movement. Meanwhile, the PLC end calculates the current outer diameter and caliber specification of the cast pipe in real time according to the data measured by the first laser distance meter, and drives the extension and retraction crank arm 2 to start to descend to the designated height. When the first laser switch and the second laser switch sequentially sense the cast pipe and the third laser switch and the fourth laser switch do not sense the cast pipe, the PLC end stops moving horizontally and detects whether the vertical descending height reaches. And if the vertical height is reached, the cylinder is driven to extend the measuring machine body, and when the fifth laser switch senses the backward movement of the measuring machine body, the measuring probe is determined to reach the surface of the casting pipe and be attached. At this time, the PLC end drives the axial guide wheel to start moving toward the socket at a medium-high speed, and starts the thickness measuring operation. When the measuring machine body quickly reaches the socket, the outer diameter of the socket is enlarged to form a slope, so that the distance detected by the first laser range finder is gradually smaller than the distance detected by the second laser range finder. At the same time, the third laser switch also detects the slope of the socket. At the moment, the PLC rapidly drives the cylinder and the stretching and retracting crank arm, retracts the measuring probe and raises the stretching and retracting crank arm. And the PLC end decelerates to a standby interval in the direction of the socket and stops. In the process, the maximum range of the dead zone of the socket position does not exceed the distance between the second laser switch and the fourth laser switch; the maximum range of the socket blind area is not more than the distance between the third laser switch and the first laser switch.
When the measuring probe runs from the socket to the socket for thickness measurement: firstly, the PLC end system controls the axial guide wheel to move towards the socket at a medium speed at a constant speed. When the second laser range finder detects the cast tube, the axial guide wheel reduces the speed to low speed movement. When the first laser range finder also detects the cast pipe, the PLC compares the data measured by the first laser range finder and the data measured by the second laser range finder, and if the distance data of the first laser range finder is smaller than that of the second laser range finder, the PLC determines that the measuring probe is still in the slope area of the socket; if the distance data of the first laser range finder and the second laser range finder are basically consistent, the measuring probe is considered to reach the horizontal detection area; the PLC end calculates the current specification of the outer diameter and the caliber of the cast pipe in real time and drives the stretching and retracting crank arm 2 to start to descend to the designated height. When the first laser switch, the second laser switch and the fourth laser switch sense the cast pipe, the PLC end drives the air cylinder to extend the measuring machine body, and when the fifth laser switch senses the backward movement of the measuring machine body, the measuring probe is determined to reach the surface of the cast pipe and be attached. At this time, the PLC end drives the axial guide wheel to start moving in the direction of the socket at a medium-high speed, and starts the thickness measuring operation. When the measuring machine body quickly reaches the socket, firstly the second laser range finder cannot detect the cast pipe, secondly the fourth laser switch cannot detect the cast pipe, and then when the second laser switch cannot detect the cast pipe, the PLC end rapidly drives the cylinder and the stretching and retracting arm, the measuring probe is folded, and the stretching and retracting arm is lifted. And the PLC terminal decelerates to run to the standby interval in the socket direction and stops. In the process, the maximum range of the dead zone of the socket position is the distance between the second laser switch and the probe, and the dead zone can be calculated as no dead zone because the second laser switch and the measuring probe are at the same position; the largest range of the socket blind area is the distance between the first laser range finder and the fifth laser switch.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
