钻机短距离快速移动装置能够提高煤矿全液压坑道钻机的移动速度,针对钻机在有轨道巷道短距离移动的情况,设计了一种轨道卡紧机构即卡轨。在使用过程中,偏心连杆尾部的偏心圆推动夹板夹紧轨道,使卡轨作为钻机移动的支点。此外,为使偏心圆具有自锁功能,通过计算选择了合适的偏心距及回转轴半径。
The short distance fast moving device of drilling rig can improve the moving speed of full hydraulic tunnel drilling rig. Aiming at the situation that the drilling rig moves in the short distance of the track, the design of a track clamping mechanism, ie, the track, is designed. During use, the eccentric circle at the tail of the eccentric rod pushes the clamp clamping rail to make the rail as the fulcrum of the drill moving. In addition, in order to make the eccentric circle has the self-locking function, the proper eccentricity and the radius of the rotary shaft are selected by calculation.
