The invention discloses a device for increasing motor torque by pulling a heavy object by upper limb pulleys. The device comprises springs, movable pulleys, fixed pulleys, supports, rubber latex rings and silk threads. The supports are close to the load end, the silk threads are connected with the heavy object, and bypass grooves of the movable pulleys, and the other ends are fixedly connected with the supports. The silk threads connected to movable pulley shafts penetrate through support silk thread passing side holes to bypass the next pulley groove, the silk threads are led out of the movable pulley shafts to be connected with the lifted heavy object or the next pulley groove, the movable pulleys can slide in the supports, and the springs which are wrapped and fixed by a soft material are arranged at the ends of the supports where the pulleys are located. The pre-tightened rubber latex rings are fixedly connected in a sliding way where the movable pulley shafts is located, the soft material wrapping objects at the ends of the springs and compression springs or other linear springs can relieve collision with the end portions of the supports due to the fact that the heavy object pulls the silk threads, and meanwhile the effect can be further relieved through the stretched rubber latex rings. The motor torque can be increased when a motor pulls the heavy object by increasing or decreasing the number of the pulley blocks.
本发明公开了一种上肢滑轮牵拉重物电机扭矩提升装置,包括弹簧、动滑轮、定滑轮、支架、胶乳胶圈、和丝线。支架接近负载端丝线接重物,绕过动滑轮的槽,另一端与支架固接。动滑轮轴上所接丝线穿过支架丝线通过侧孔绕过下一个滑轮槽,动滑轮轴引出丝线与所提重物或者下一级滑轮槽相连,所述动滑轮可在支架中滑动,在滑轮所在支架端部有被软性材料包覆且固定的弹簧,以及在动滑轮轴部所在滑道内固接有预紧的胶乳胶圈,弹簧端部软性材料包覆物及压缩弹簧或者其他直线形式弹簧可以减轻由于重物拉动丝线而导致的与支架端部碰撞,同时被拉伸的胶乳胶圈也可进一步减轻该效果,并可进行增减滑轮组数目来达到电机牵拉重物时提升电机扭矩的作用。
