Design and application of belt lifting mechanism for replacing idler of belt conveyor
摘要
Abstract
Aiming at the problems of the frequent idler failure of long-haul large belt conveyor,idler replacement work leading to shutdown,and the low efficiency and single equipment of traditional manual idler replacement,a robot that can realize non-stop idler replacement is proposed to improve the idler replacement efficiency by taking the belt conveyor in the main adit of Wangjialing Coal Mine as the research object.The belt lifting mechanism is an important part of idler replacement robot.Based on the functional requirements of the robot and the characteristics of narrow space and large belt load of belt conveyors,a scissor-fork belt lifting mechanism was designed.Firstly,the three-dimensional model of the scissor-fork belt lifting mechanism was constructed by SolidWorks software.After the working load of belt lifting was calculated according to the parameters of the belt conveyor,the force analysis for belt lifting mechanism was carried out.Then,the kinematics simulation analysis for belt lifting mechanism was conducted by SolidWorks Motion module and the statics simulation analysis was carried out by ANSYS Workbench finite element software.Finally,the ground test and underground test were carried out to verify the feasibility of the designed belt lifting mechanism.The ground test results showed that under the load of 20‒60 kN,the matching accuracy between the measured and simulated vertical displacement of the belt lifting mechanism was 6%‒15%,which verified that the bearing capacity of its main structure met the design requirements.The underground test results proved the rationality and reliability of the belt lifting mechanism design.The bearing capacity and lifting height of the scissor-fork belt lifting mechanism meet the functional requirements of the idler replacement robot,which is a key technical breakthrough to realize the non-stop replacement of idlers for belt conveyors.关键词
