A device for preventing a traction steel cable from falling comprises two bottom plates hinged to each other, the upper portion of each bottom plate is provided with a group of bearing seats, each group of bearing seats is rotatably connected with a roll shaft, the steel cable crosses a
coal pile under the guidance of the bearing seats and the roll shafts, a lead screw for adjusting the included angle of the two bottom plates is arranged between the two bottom plates, and a fixing rod is arranged on the outer side of each bottom plate. The two hinged bottom plates are placed at the top of a
coal pile, so that the steel cable can leave the
coal pile on the two sides of the coal pile and is prevented from falling into the coal pile, the outer contour
diameter of each bearing seat is larger than the
diameter of the roller shaft, and the steel cable can slide between the bearing seats on the two sides when bypassing the device, so that the steel cable can be prevented from being separated from the device; the rotating roll shaft can isolate the steel cable from the coal pile and prevent the steel cable from falling into the coal pile, sliding friction of the steel cable and the roll shaft is converted into rolling friction,
friction force is greatly reduced, abrasion of the steel cable is reduced, the included angle of the two bottom plate supports can be adjusted through the lead screw, and the device can adapt to inclination angles of the tops of different coal piles. Meanwhile, the distance between the steel cable and the top of the coal pile can be adjusted, the steel cable is further prevented from making contact with the coal pile, the fixing rods are inserted into the coal pile, the device and the coal pile can be better fixed, and the device is prevented from shaking when pressed.
