A device for preventing a traction steel cable from falling comprises a supporting frame, gears are rotationally connected to the two sides of the supporting frame respectively, a rack frame is arranged on the upper portion of the supporting frame, racks on the two sides of the rack frame are meshed with the gears on the two sides, release blocks are slidably connected to the two sides of the supporting frame respectively, a shaft is arranged between the two release blocks, and a pulley is fixedly connected to the outer side of the shaft. The steel cable is rotationally connected with the pulley, a swash plate is arranged on the side, connected with the canvas, of the steel cable, the inclined face of the swash plate makes contact with the inclined face of a wedge block in the middle of the rack frame to drive the rack frame to rise, and the release block, the gear and the rack frame are matched to position the shaft in the release block or release the shaft from the release block. The shaft is positioned at a high position by the supporting frames, the releasing blocks and the gears on the two sides, the steel cable is lifted when bypassing the pulleys on the shaft, the steel cable and the slope of the coal pile form a certain dip angle, the steel cable and canvas cannot sink into the coal pile, the slope of the swash plate makes contact with the slope of the rack frame, the swash plate pushes the rack frame upwards, and when the rack frame moves upwards, the racks on the two sides drive the gears to rotate. When the gear rotates, the half shaft rotates into the shaft hole in the opposite side of the semicircular hole from one side of the semicircular hole, the release block and the shaft roll down from the release groove under the action of gravity, and at the moment, the steel cable pulls the canvas to penetrate through the bottom of the supporting frame without obstacles.
一种防止牵引钢索陷落的装置,包括支撑架,所述支撑架两侧分别转动连接齿轮,支撑架上部设有齿条架,齿条架两侧的齿条和两侧的齿轮相互啮合,支撑架两侧分别滑动连接释放块,两个释放块中间设有轴,轴外侧固定连接滑轮,钢索转动连接滑轮,钢索连接帆布一侧设有斜盘,斜盘的斜面和齿条架中间的楔块斜面接触时带动齿条架升起,释放块、齿轮、齿条架相互配合将轴定位在释放块中或者从释放块中释放,卷扬机工作时,轴被两侧的支撑架、释放块和齿轮定位在高处,钢索绕过轴上的滑轮时被抬高,钢索和煤堆斜面具有一定的倾角,钢索和帆布不会陷入煤堆中,斜盘斜面和齿条架斜面接触,斜盘将齿条架往上推动,齿条架往上移动时,两侧的齿条带动齿轮转动,齿轮转动时,半轴从半圆孔一侧转动到半圆孔相对一侧的轴孔中,释放块和轴在重力作用下从释放槽中滚落,此时钢索拉动帆布从支撑架底部无障碍的穿过。
