针对回采巷道超前支护中单体液压支柱回收搬运困难的现状,设计了伸缩式单体柱运输车,告别了回采巷道搬运单体柱依靠工人肩扛的历史。该设计通过伸缩式车体,可以运输各种型号单体柱。在车体底梁两端设计有弧形限位梁,能有效防止单体柱在运输途中来回滚动以致滚落而发生安全事故。该设计结构简单,功能强大,解决了回采巷道运输单体柱难的问题,并消除了工人肩扛存在的安全隐患。通过工程实践证明,该设计成果显著,值得推广。 In view of the current situation of recovery and transportation of single hydraulic props in advance support of mining roadways, a retractable single-column truck was designed and bid farewell to the historical history of single-column propping on roadway carrying workers. The design through the telescopic body, you can transport all types of single column. At both ends of the car body beam designed arc limit beam, can effectively prevent the monolithic column from rolling back and forth during transport so as to roll over and cause a safety accident. The design is simple in structure and powerful in function, which solves the difficult problem of transporting single columns in the mining roadway and eliminates the potential safety hazard of workers shouldering the shoulder. Proved through engineering practice, the design results are significant and worth promoting.
