The invention provides a traction device for assisting in fan hoisting, and belongs to the technical field of cranes. Fixing piles in two traction units directly face a boom of a crane, and a certaindistance exists between the fixing piles and the boom of the crane. A traction sliding frame arranged on a tensioning rope in a sleeving mode moves along the tensioning rope to adjust the position ofa heavy object traction rope connected to the traction sliding frame so as to adjust the position of a blade which is lifted by the crane and connected with the second end of the heavy object tractionrope. The position of the traction sliding frame relative to the tensioning rope is adjusted through a steel wire rope of a lifting winch arranged at the first ends of the fixed piles. In the processthat the blade is lifted by the crane, the heavy object traction ropes in the two traction units and a steel wire rope of the crane for lifting the blade form a herringbone shape, and blade shaking is reduced. And the heavy object traction rope applies acting force for away from the crane boom to the blade, so that the possibility that the blade impacts the crane boom is reduced, and the safety of the blade in a hoisting process is improved.

    本公开提供了一种辅助风机起吊的牵引装置,属于起重机技术领域。两个牵引单元中的固定桩均正对起重机的臂架并与起重机的臂架之间存在一定的距离。套设在张紧绳上的牵引滑动架沿张紧绳移动,调整牵引滑动架上连接的重物牵引绳的位置,对被起重机提升且与重物牵引绳的第二端连接的叶片的位置。牵引滑动架相对张紧绳的位置的调整通过设置在固定桩的第一端上的提升绞车的钢丝绳实现。在叶片被起重机提升的过程中,两个牵引单元中的重物牵引绳与提升叶片的起重机的钢丝绳构成人字形,减小叶片晃动。且重物牵引绳为叶片施加远离起重机臂架的作用力,减小叶片撞击起重机的臂架的可能,提高叶片在起吊过程中的安全性。
