摘要
针对现有开槽机的不足,基于井下开槽作业需求,设计开发了大折展比开槽机械臂构型,并建立了其运动学分析模型,分析得出所开发的机械臂最大作业高度为4280 mm,最大作业深度为2706 mm,最大作业宽度为4212.5 mm。将其应用于开槽机,在一次定位开全槽的要求下,适应最小巷道高度为3000 mm;适应最小巷道宽度为4200 mm,此时可适应最大巷道高度为5039 mm;适应最大巷道宽度为5400 mm,此时可适应最大巷道高度为4500 mm,可覆盖70%以上的巷道断面尺寸。
Aiming at the technical deficiency of existing slotting machine,based on the requirements of slotting operations,a large span ratio manipulator configuration was proposed,and the kinematic analysis model was established.The analysis results show the maximum working height is 4280 mm,the maximum operating depth is 2706 mm,the maximum operating width is 4212.5 mm.It was applied to slotting machine.Under the require of once location full slotting,it can adapt to the construction requirements of minimum roadway height of 3000 mm.The minimum roadway width is 4200 mm,and the maximum roadway height can be 5039 mm.The maximum roadway width is 5400 mm,and the maximum roadway height is 4500 mm.It can cover more than 70%of the roadway section size.
