This machine with advantage of slow speed, compact structure and big traction force. The prop-drawing winch is mainly used to prop drawing and caving roof in coal working face, but also can be used to relocate the equipment in fully mechanized coal face,such as uphill, downhill, and level gallery working face. Because of its low height and light weight, The prop-drawing winch is suitable for the thin coal seam and steep coal seam, and recovering the various metal pillar which Sinking into the floor or buried by gangue. The JH-14 prop-drawing winch is designed based on my Practice on graduation practice last years and consulting large numbers of information, Which also combines many of my new ideas. The design process in the speed reducer, mainly used in the worm-gear transmission, double-slip gear transmission and column gear transmission etc transmission way. slide the small double-gear with the fork-lever to achieve Speed Change. But also in the fork-lever of the design, I used the handle shake rotary table to achieve the fork-lever horizontal movement. The prop-drawing winch drum in the design, taking into account the design precision need not too high,so I put a drum axis change into connection of drum and axis with interference fitting and welding in Both ends of the drum, reduced the Materials of axis, to avoid the waste of materials. The main features of the design is to achieve speed change, it can satisfy the different working environment, but also to make the prop-drawing winch use different speeds to achieve the rapid return to prop drawing in the back rope and up rope.
