The invention relates to a gravity balanced elevator. The gravity balanced elevator comprises an elevator shaft, wherein the elevator shaft is internally provided with an elevator car, an elevator counterweight, a traction machine and a steel wire rope, the traction machine is fixedly arranged at the top of the elevator shaft, the center of the steel wire rope and the traction machine are wound,the two ends of the steel wire rope are respectively connected with the tops of the elevator car and the elevator counterweight, the elevator car is fixedly connected with a first balance water tank,the elevator counterweight is fixedly connected with a second balance water tank, the elevator shaft is fixedly connected with a balance water box, the first balance water tank communicates with a first water inlet pipe and a first water outlet pipe, the other ends of the first water inlet pipe and the first water outlet pipe communicate with the balance water box, and the second balance water tank communicates with a second water inlet pipe and a second water outlet pipe. Compared with existing elevators, at run time, the elevator and counterweight can change own weight in real time accordingto the weight relationship through the water flow transmission of the water tanks and the water box, so as to achieve the weight balance of the counterweight and the elevator car, and the traction burden of the traction machine is reduced.
本发明涉及一种重力平衡的电梯,包括电梯井道,电梯井道内设置有电梯轿厢、电梯对重、曳引机、钢丝绳,曳引机固定设置于电梯井道的顶部,钢丝绳中心与曳引机缠绕,钢丝绳的两端分别连接电梯轿厢和电梯对重的顶部,电梯轿厢固定连接有第一平衡水槽,电梯对重固定连接有第二平衡水槽,电梯井道固定连接有平衡水箱,第一平衡水槽连通有第一进水管和第一出水管,第一入水管和第一出水管的另一端均与平衡水箱连通,第二平衡水槽连通有第二进水管和第二出水管。相比于现有的电梯,本发明在运行时电梯和对重能够实时的根据重量关系、通过水槽和水箱的水流传输以改变自身重量,从而达到对重和轿厢的重量平衡,减轻曳引机的牵引负担。
