Small-sized prying trolley working arm
The invention relates to the technical field of mine roadway repair, in particular to a small-sized prying trolley working arm which comprises a prying trolley body, a working arm body and a pin shaft. The working arm body is formed by combining a breaking hammer, a first spiral swing oil cylinder, a second spiral swing oil cylinder, a telescopic inner barrel, a main arm, a telescopic inner barrel protection cover, a telescopic inner barrel circumferential limiting block, a telescopic oil cylinder, a pitching oil cylinder, a main arm rotating seat and a rotating speed reducer, and the rotating speed reducer is installed on the prying trolley body. Under the same impact load, the overall length of the working arm in a fully folded state is minimum, the structure is compact, the length, width and height of the prying trolley body are reduced, the overall influence of the roadway size on the prying trolley is small, the trafficability is good, the operation actions are minimum when the working arm works, and rapid and accurate positioning can be achieved.
本发明涉及矿山巷道修复技术领域，特别是涉及一种小型撬毛台车工作臂，包括撬毛台车本体、工作臂本体和销轴，所述工作臂本体固定安装在撬毛台车本体上，所述工作臂本体由破碎锤、第一螺旋摆动油缸、第二螺旋摆动油缸、伸缩内筒、主臂、伸缩内筒保护罩、伸缩内筒周向限位块、伸缩油缸、俯仰油缸、主臂回转座、回转减速器组合形成，所述回转减速器安装在撬毛台车本体上，本发明在相同工作范围，相同冲击载荷下，工作臂总体收回完全折叠状态长度最小，结构紧凑从而实现撬毛台车本体尺寸长度、宽度和高度的缩小，撬毛台车总体受巷道尺寸影响小通过性好，工作臂工作时操作动作最少、可以快速精准定位。
