Rope winding device for pulley in Shower room pulley
Pulley block
Pulley block: a pulley device composed of fixed pulley and Shower room pulley movable pulley. It can save labor and change the direction of force But you can't save work, because the pulley block saves labor, but it takes a long distance. In order to save energy and change the direction of power, the fixed pulley and moving pulley can be combined into a pulley block.
Rope winding method
Deformed pulley block
The pulley block is formed by matching several fixed pulleys and moving pulleys, which can save labor and change the direction of force action. In use, the amount of labor saved and the winding method of the rope depend on the use effect of the pulley block. The principle of rope winding is: when the number of fixed pulley and movable pulley is equal, the free end of the rope can come out from the driven pulley or from the fixed pulley, and when coming out from the fixed pulley, the fixed end of the rope is hung on the fixed pulley; When the driven pulley comes out, the fixed end of the rope is hung on the movable pulley. The number difference between fixed pulley and movable pulley shall not exceed 1. When their numbers are not equal, the free end of the rope comes out from the more side and the fixed end of the rope hangs on the less side. When the movable pulley is fixed, when the fixed end of the rope is hung on the movable pulley, the pulley block saves labor than when the fixed end of the rope is hung on the fixed pulley (because there Shower room pulley are more sections of rope to bear the weight).
