The invention discloses a coal mine conveying vehicle, and relates to the technical field of coal mine electromechanical equipment. The vehicle comprises a frame, the frame comprises a bottom plate and vertical plates, the vertical plates are arranged at the two opposite side edges of the bottom plate, half-kidney-shaped holes are formed in the tops of the vertical plates, two mounting bases are symmetrically arranged on the bottom faces of the vertical plates, sliding grooves are formed in the mounting bases, and cavities communicating with the half-kidney-shaped holes and the sliding grooves are formed in one side faces of the vertical plates; a hopper is rotationally installed between the two vertical plates, and a shaft body of the hopper is installed in the clamping part in a matched mode and is fixed through a fixing part fixedly installed at the top end of the half-kidney-shaped hole. Rollers are rotationally mounted at the bottoms of the sliding grooves, friction parts making contact with roller shaft bodies are further mounted in the sliding grooves, and the tops of the friction parts make contact with the elastic pieces. The hopper filled with a coal mine pushes the corresponding sliding rods on the transverse rod to slide downwards under the action of gravity, the first V-shaped rod is pushed to rotate, the friction blocks are pushed to be tightly attached to the rotating shafts of the rolling wheels, and the speed reducing and braking effects are achieved.
本发明公开了一种煤矿输送车,涉及煤矿机电设备技术领域。本发明包括框架,框架包括底板和立板,底板的相对两侧边上均设置设有立板,立板的顶部开有半腰型孔,立板的底面对称设有两安装座,安装座上开有滑动槽,立板的一侧面上设有与半腰型孔和滑动槽连通的腔体;两立板之间转动安装有料斗,料斗的轴体配合安装在卡接部内,并通过半腰型孔顶端固定安装有固定部进行固定;滑动槽的底部转动安装有滚轮,滑动槽内还安装有与滚轮轴体接触的摩擦部,摩擦部的顶部与弹性件接触。本发明通过装有煤矿的料斗在重力的作用下推动横杆上对应的滑动杆向下滑动,实现推动V型杆一转动,并推动摩擦块贴紧滚轮的转轴,达到减速制动的效果。
