Abstract:
Considering that existing pipeline installation robots are unable to achieve common pipeline lifting and installation on excavation faces, this paper studies a pipeline installation robot specifically designed for excavation faces. Taking the working conditions of the excavation face in Lijiahao Coal Mine as the project background, the overall scheme design of the pipeline installation vehicle is carried out. In order to reduce the repeated grasping and lifting of pipelines by personnel control equipment, the overall scheme of the pipeline installation robot control system is formulated, and the motion analysis of the pipeline installation robot is carried out. The D-H method is used to establish its kinematic model, and the kinematics is solved to analyze the working space of the robotic arm. To verify the kinematic characteristics of the installation robot designed in this paper and the accuracy of the established kinematic model, a kinematic forward and inverse solution program is written using MATLAB software. A 3D model of the robot is established using SolidWorks and imported into MATLAB software to observe the motion state of the robot during pipeline grasping and installation, and to verify that the designed robotic arm meets the requirements of pipeline installation. Experimental research is conducted on the installation robot of coal mine excavation face pipelines on the ground. The test results show that the pipeline installation robot designed in this study can grasp pipelines with a diameter of φ108-φ500 mm and lift them to a height of over 5 000 mm. It can replace manual labor to complete pipeline grasping and lifting functions underground, reducing the labor intensity of workers.
