A Pre-calibration Method for Concrete Distributor

In the production process of precast concrete components, to solve the problem that concrete distributor cannot automatically determine the pre-calibration point, the automatic pre-calibration method for concrete distributor is proposed based on the marking of bottom-mold-tray and the proximity switch in this paper. The above method is achieved through marking the placement position of the magnetic-side-molds at the corner on the bottom-mold-tray and using the positioning equipment of the bottom-mold-tray. Then, the pre-calibration point of the concrete distributor is indirectly determined with relevant position information. The designed automatic pre-calibration method not only reduces the pre-calibration time, improves the accuracy and efficiency of the pre-calibration point of the concrete distributor, but also has the advantages of good compatibility with the original control system of the concrete distributor, easy development and low transformation cost.
