Four-lifting-point winch hoist
The invention discloses a four-lifting-point winch hoist. The four-lifting-point winch hoist comprises a rack, four evenly-distributed lifting points are arranged at the bottom of the rack, each lifting point is dragged by a movable pulley block, a steel wire rope is wound around the bottom of the movable pulley block, one end of the steel wire rope is fixed to a balance pulley in a wound mode, the other end of the steel wire rope is fixed to a roller in a wound mode, every two of the four rollers form a group, the rollers in the same group rotate through meshing, the two rollers in each group are at least provided with a group of motor driving mechanisms, and the two rollers in the adjacent groups are at least provided with a transmission shaft for transmission connection; four large gears are divided into two sets to be meshed and rigidly connected, then the two sets of gears are connected through the transmission shaft, synchronous and same-stroke power transmission is achieved, output opening and closing force of each lifting point can be dynamically adjusted when stress on the four lifting points is not uniform, and dynamic balance of a whole opening and closing system is achieved.
本发明公开了一种四吊点卷扬启闭机，包括机架，机架的底部设有四个均匀分布的吊点，每个吊点均由一个动滑轮组牵引，钢丝绳由动滑轮组底部绕过，钢丝绳的一端缠绕固定在平衡滑轮上，钢丝绳的另一端缠绕固定在滚筒上，四个滚筒每两个构成一组，同组滚筒的转动通过啮合，每组的两个滚筒至少设有一组电机驱动机构，相邻组的两个滚筒至少提供一个传动轴传动连接；本发明通过四个大齿轮分成两组咬合硬接，再通过传动轴将两组齿轮连接，实现同步同行程的动力传递，在四个吊点受力不均匀时可以动态调整各个吊点的输出启闭力，达到整个启闭系统的动态平衡。
