Two -way material hoist

The utility model discloses a two -way material hoist. Including pressing rope mechanism, linking board, driving -disc, box, be provided with the driving -disc on the box, the driving -disc bilateralsymmetry is provided with presses rope mechanism, press the rope interagency through even board connection, press rope mechanism swingingly to set up on the box, when one side wire rope has the heavyobject, press wire rope in the driving -disc through the pressure rope mechanism that links board pulling opposite side. The utility model discloses a pressure of two sets of symmetries rope mechanismcan two -way heavy lift, improves work efficiency. Transmission when using compression spring to pass through lever principle realization empty load in the two casing pressures rope mechanism. 本实用新型公开了种双向物料提升机。包括压绳机构、连板、驱动盘、箱体；所述箱体上设置有驱动盘，所述驱动盘两侧对称设置有压绳机构，所述压绳机构间通过连板连接，所述压绳机构可摆动地设置在箱体上；当侧钢丝绳有重物时，通过连板拉动另侧的压绳机构将钢丝绳压在驱动盘内。本实用新型采用二套对称的压绳机构，可以双向提升重物，提高工作效率。二套压绳机构上使用压缩弹簧通过杠杆原理实现空载时的传动。
