Problems solved by technology

[0003] Due to the lack of the key technology of pre-calibration for concrete placing machines in the industry, the control system of the placing machine cannot automatically determine the position of the placing machine relative to the magnetic side form, which also affects the development and implementation of the subsequent automatic placing control function, resulting in the current concrete placing. The machine can only produce fabrics in manual operation mode, and at the same time, it needs to be equipped with a number of production assistants to assist in the uniform distribution with shovels, which not only causes problems such as low production efficiency and unstable product quality, but also poses safety hazards

Abstract

The invention provides a concrete distributor automatic pre-calibration method based on laser ranging, and relates to the field of automatic control of prefabricated component concrete distributors inbuilding industrialization. The method comprises the steps that a laser distance sensor is mounted, and meanwhile the axis X and the axis Y are determined; the distance between the laser distance sensor and a bottom mold tray and the distance between the laser distance sensor and a magnetic side mold are measured, and the permissible error range is set; the initial position that a distributor arrives at the position outside a distribution area is controlled, and a controller is utilized for recording the pre-calibration point of the laser distance sensor of the distributor; the pre-calibration point of the distributor is calculated by the controller; and the relative position of the distributor is calculated, the distributor is controlled by the controller to move to the pre-calibration point, and distribution production is prepared. According to the method, modification to existing equipment and detection systems is small, the modification cost is low, compatibility with existing distribution systems is good, and operation is easy to implement; and meanwhile, pre-calibration of the distributor can be completed automatically, and the accuracy that the concrete distributor determines the pre-calibration point and the pre-calibration efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of automatic control of prefabricated component concrete distribution machines in building industrialization, in particular to an automatic pre-calibration method for concrete distribution machines based on laser distance measurement. Background technique [0002] The concrete placing machine is the key equipment for the factory production of concrete prefabricated components. The higher the level of automation, the shorter the production time of the concrete placing machine, which is more helpful to improve the production efficiency of prefabricated components and reduce and save human resource investment. The pre-calibration technology of the concrete placing machine mainly adopts an automatic method, by finding the position of the magnetic side formwork on the bottom mold tray to determine the starting point of the placing machine to start laying, and then enabling the placing machine control system to con...
