An online monitoring device for steel wire tension on a wire winding machine

Abstract

The invention relates to an online steel wire tension monitoring device on a wire winder, in particular relating to a tension measurement mechanism of a wire winder for producing pre-tension concrete pipes. The online steel wire tension monitoring device can ensure accurate data output for long term without stopping. The wire winder comprises a controller and a tension generating motor. The online monitoring device comprises a fixed cradle, a force sensing device and a steel wire suspension wheel, wherein the fixed cradle is arranged on a steel wire walking path; the force sensing device is used for connecting the steel wire suspension wheel and the fixed cradle; the steel wire suspension wheel is used for suspending the steel wire above the steel wire walking path; the force sensing device is connected with the controller; and the tension generating motor is connected with the controller. The online steel wire tension monitoring device is different from the prior art in the working mode that only a single measurement device is adopted to collect the tension data; and the force sensing device consisting of a plurality of sensors integrated together is adopted, therefore the possibility that a fault occurs on the plurality of sensors at the same time is extremely small, so that the disabled sensor can be repaired and replaced after an apparatus is ensured to complete the continuous processing of a workpiece. Therefore, the online steel wire tension monitoring device can be used for greatly improving the product quality and the processing efficiency.

Description

technical field [0001] The invention relates to a tension measuring mechanism of a wire wrapping machine used in the production of pre-tensioned concrete pipes, especially a tension measuring mechanism in the production of pressure pipes such as PCCP (Prestressed Concrete Cylinder Pipe) and three-stage pipes . Background technique [0002] In order to ensure that the tension generated by the high-strength steel wire wound on the outer wall of the pre-tensioned concrete pipe is a constant value, there is a set of devices in the wire winding machine specially used to detect the magnitude of the tension and a tension measuring mechanism. The tension measuring mechanism is mainly composed of a tension wheel, and a frame. Connected shaft, pressure sensor, connecting bearing housing, bearing and so on. The actual tension value measured by the pressure sensor is transmitted to the PLC, and then the corresponding processing is performed. In the entire winding system, if the measure...

Problems solved by technology

[0004] 1. The workload of calibrating the scale is relatively large;

[0005] 2. In order to calibrate the scale, the production must be stopped, which affects the production efficiency;

[0006] 3. It takes a long time to calibrate the scale once a week. When the scale is damaged, it can only be found when the scale is calibrated;

[0007] In other words, if there is a tension change and the scale cannot correctly reflect the tension value, then during this period of time, the processed products are all out of control products; it is easy to cause heavy losses to production and bring great losses to users. harm
