摘　　要：为解决传统井下密闭墙浇筑效率低,施工难度大的难题,研发了新型井下双动力防爆混凝土泵送车。由于井下有限空间整车不能满足巷道上料高度要求,泵送车臂架采用回转伸缩式,能够承受混凝土及输送管重量强度,井下双动力混凝土泵送车拥有创新的尺寸外形与臂架设计室。混凝土泵送车的控制方式采用无线遥控电比例的负载敏感多路阀,通过电气控制系统实现双动力之间的切换,将外部电源和底盘电源融合,从而保证行车状态时泵送及臂架锁止。煤矿井下混凝土密闭墙等工程采用混凝土泵送技术,能够显著节约人力与物力,提高生产效率,增强安全性,为提升井下复杂环境密闭墙浇筑作业效率提供了有价值的技术参考。To address the challenges of low efficiency and high construction difficulty in traditional underground mine seal wall pouring,a new type underground dual-power explosion-proof concrete pump truck is developed.Due to the limited underground space of the whole vehicle can not meet the loading height of the roadway,the pump truck boom adopts rotary retractable type,which can withstand the weight strength of concrete and conveying pipe.The control mode adopts wireless remote control electric proportional load sensitive multi-way valve.The switch between the dual power is realized through the electrical control system,and the external power supply and chassis power supply are integrated to ensure the pumping and boom locking in the running state.The unique dimension and shape as well as the innovative boom design of the underground dual-power concrete pumping truck room greatly saves manpower and material resources,improves production efficiency and increases safety for sealing wall pouring operation in complicated environment of underground coal mine.
