The invention discloses a car counterweight with the weight capable of being adjusted in a stepless mode. The car counterweight comprises a box body, wherein a water inlet groove is formed in the upper end of the box body; a first water outlet pipeline is arranged at the lower end of the box body; a groove is formed in the inner wall of an elevator shaft; a water inlet pipe is arranged at the position, corresponding to the water inlet groove, in the groove; the water inlet pipe is connected with a water source through a hose; and a second water outlet pipeline is arranged at the position, corresponding to the first water outlet pipeline, in the groove. When people enter a car, the weight in the car is increased, water enters the box body through the water inlet pipe and the water inlet groove, and the weight of the counterweight is increased; and when people leave the car, the weight in the car is reduced, the water inlet groove in the upper end of the box body rotates anticlockwise, the water in the box body enters a recycling box through the first water outlet pipeline and the second water outlet pipeline, and the weight of the counterweight is reduced. Stepless adjustment of the weight of the car is achieved, the counterweight balances the weight of the car, the car can ascend and descend through a small traction machine, and the power of the traction machine is reduced.
本发明公开的一种重量可无极调节的轿厢配重,包括箱体,所述箱体上端设有进水槽,箱体下端设有第一出水管道,电梯井内壁上设有凹槽,凹槽内与进水槽对应的位置设有进水管,进水管通过软管连接水源,凹槽内与第一出水管道对应的位置设有第二出水管道。当轿厢中进入人时,轿厢内重量增加,水经过进水管、进水槽进入到箱体中,配重重量增加;当轿厢中走出人时,轿厢内重量减少,箱体上端的进水槽逆时针转动,箱体内的水经过第一出水管道和第二出水管道进入到回收箱中,配重重量降低。实现了轿厢重量的无级调节,并且能够保证配重平衡轿厢的重量,很小的曳引机即可实现轿厢的升降,降低曳引机的功率。
