The invention discloses dust falling equipment for mining and tunneling of a steeply inclined coal seam, and relates to the technical field of coal seam mining, according to the technical scheme, the dust falling equipment comprises an equipment base, four damping wheels are arranged at the bottom of the equipment base, the equipment can be cushioned through the damping wheels in the moving process, and speed limiting mechanisms are further arranged in the damping wheels; resistance can be provided for the moving wheels when the moving wheels move too fast through the speed limiting mechanisms, the steeply inclined coal seam is generally large in inclination angle, the speed is difficult to control in the equipment moving process, and when a speed sensor arranged on one side of each moving wheel monitors that the rotating speed of the moving wheels is too high, the speed limiting mechanisms arranged at the upper ends of the cushioning shells can be controlled to start, so that the moving wheels move too fast. The two speed limiting pieces arranged at the bottom are driven by the speed limiting mechanism to be closed inwards, so that pressure is applied to the two sides of the moving wheel, the friction force borne by the moving wheel during rotation is increased, the rotating speed of the moving wheel is reduced, and the using effect of the equipment in the steeply inclined coal seam is effectively improved.
本发明公开了一种急倾斜煤层开采掘进用降尘设备,涉及煤层开采技术领域,其技术方案包括设备底座,设备底座底部设置有四个减震轮,通过减震轮可在移动过程中为设备通过缓震,缓震轮内部还设置有限速机构,通过限速机构可在移动轮移动过快时向移动轮提供阻力,本发明中,急倾斜煤层一般倾角较大,设备移动过程中速度难以控制,当设置在移动轮一侧的速度传感器监测到移动轮的转速过快时,可控制缓震壳体上端设置的限速机构启动,通过限速机构带动底部设置的两个限速件向内闭合,从而给予移动轮两侧压力,提高移动轮转动时受到的摩擦力,进而降低移动轮的转速,有效提高了设备在急倾斜煤层内的使用效果。
