AI Technical Summary

Technical Problem

In the current coal transportation process, the formation of clumps on the inner walls of coal transport vehicles leads to a decrease in loading volume, reduced unloading efficiency, and high operational risks and inefficiency. Furthermore, there is a lack of automated solutions for accurately locating the clumps.

Method used

By employing automated positioning and 3D scanning technology to accurately identify the spatial distribution of clumps, combined with high-pressure water jet directional removal, and by acquiring coordinate data of the inner wall of the carriage through 3D laser scanning to identify differential coordinate sets, the optimal path of the robotic arm is planned, and the parameters of the high-pressure water gun are monitored and dynamically adjusted in real time to achieve efficient removal of clumps.

Benefits of technology

It significantly improves operational safety, avoids damage to the carriages, increases the efficiency and economy of coal transportation, and reduces energy and water consumption.

Abstract

The invention discloses a method for eliminating caking on the inner wall of a carriage of a coal carrier, which comprises the following steps of: positioning the coal carrier to a preset station, and keeping the carriage to be cleaned in a standard pose; scanning the inner wall of the carriage in the standard pose, and obtaining a first space coordinate set for calibrating the actual space position; the first space coordinate set is compared with a pre-stored reference space coordinate set, a difference coordinate set is recognized, the reference space coordinate set calibrates the space position of the inner wall of the compartment in the standard pose in the non-caking state, and the difference coordinate set calibrates the actual space position of the caking; and according to the difference coordinate set, positioning and disposing inner wall caking of the carriage. The device can be matched with railway vehicles and road transport vehicles, and the coal transport efficiency and economy are greatly improved.
