Remote intelligent monitoring method for clamping force of narrow lap welding machine clamp

Abstract

The invention discloses a remote intelligent monitoring method for the clamping force of a narrow lap welding machine clamp, and the method comprises the steps: arranging a force sensor in a clamping bolt of the narrow lap welding machine clamp, so as to monitor the clamping force of the clamp for clamping strip steel; collecting and transmitting force sensor monitoring signals to an upper computer after passing through a signal conditioning module and an analog-to-digital conversion module; enabling the upper computer to analyze and calculate the clamping state of the clamp according to the monitoring signal, set a safety threshold value of the clamping force of the clamp, compare the clamping force value of the clamp with the safety threshold value, and give an early warning signal if the clamping force value of the clamp is smaller than the safety threshold value; transmitting the early warning signal remotely to the monitoring terminal through a network, and enabling the monitoring terminal to broadcast the early warning signal and adjust the production operation state of the cold rolling galvanizing unit. According to the method, the actual clamping force of the clamp can be accurately, rapidly and effortlessly monitored, potential safety hazards cannot be caused to field maintenance personnel, the detection precision of the clamping force can be greatly improved, and the production quality of strip steel products is effectively guaranteed and improved.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to a remote intelligent monitoring method for the clamping force of a clamp of a narrow lap welding machine. Background technique [0002] Most cold-rolled galvanizing units in iron and steel production enterprises use narrow lap welding machines to lap steel strips. Action, after a long working time, the clamp that has been repeatedly pulled by the strip is prone to loosening. [0003] In view of the above problems, it is necessary to detect the actual clamping force of the clamp on-line during the movement of the clamp. The existing solution is to detect manually, that is, the on-site maintenance personnel pull the strip steel for detection by hand to perform the clamping action. Pull to judge the actual clamping force of the clamp. However, the edge of the thin steel strip is as sharp as a blade, and the thick steel strip cannot meet the needs of detection, and a la...

AI Technical Summary

Problems solved by technology

However, the edge of the thin strip is as sharp as a blade, and the thick strip cannot meet the needs of detection, and a large pulling force needs to be maintained during detection.

Therefore, the existing detection method has a very large potential safety hazard. At the same time, this detection method is related to the operating experience of on-site inspection and maintenance personnel. The pulling force is uncontrollable, unstable, and unquantified. The detection accuracy is poor, which seriously affects Subsequent strip production quality
