Abstract

The invention relates to a lifting device which is suitable for being used for lifting of a traveling crane, a gantry crane, a hoist and the like. The lifting device comprises a winding drum which is driven by a motor, a fixed pulley assembly close to the winding drum on the upper portion of the lifting device and a movable pulley assembly on the lower portion of the lifting device. The fixed pulley assembly is composed of two fixed pulley groups, and the axial directions of the fixed pulley groups are perpendicular to the axial direction of the winding drum. The movable pulley assembly is composed of two movable pulley groups, and the axial directions of the two movable pulley groups are in a V shape. The lifting device is further provided with a lifting rope. After the lifting rope crosses the two fixed pulleys on the two fixed pulley groups, two ends of the lifting rope are respectively downward wound sequentially between the movable pulley groups and the fixed pulley groups, and then, the lifting rope is wound evenly on the winding drum upward on the movable pulley groups and eventually fixedly arranged at the left end and the right end of the winding drum. The lifting device is small in appearance and size, simple in structure and light in weight.

Description

technical field

[0001] The invention relates to a hoisting device suitable for driving, gantry cranes, hoists and the like. Background technique

[0002] The existing lifting device generally adopts a plurality of fixed pulleys distributed in a single row, and the axial direction of each fixed pulley is parallel to the axial direction of the reel. This kind of lifting device has large dimensions, complex structure, and high manufacturing cost. Heavy. At the same time, the lifting device generally adopts multiple moving pulleys distributed in a single row. The axial direction of each moving pulley is parallel to the axial direction of the reel, and the radial thickness of the moving pulley is greater than the thickness of the gate, so the shape of the entire lifting device The size is large, the structure is heavy and complicated, and the appearance is not beautiful. Contents of the invention

[0003] The technical problem to be solved by the present invention is: in orde...
