Description
技术领域technical field
本发明涉及一种可自行发电的升降电梯。The invention relates to an elevator that can generate electricity by itself.
背景技术Background technique
现在大多数升降电梯的驱动原理如图1所示，为电机拽引驱动。其驱动原理如下：钢丝绳2悬挂在拽引轮3的绳槽中，一端与轿厢1连接，另一端与配重4连接。拽引轮3利用其与钢丝绳2之间的摩擦力，带动钢丝绳2继而驱动轿厢1升降。但是在两边重量相差较大的时候，拽引轮3就要给钢丝绳2较大的摩擦力，以克服重力差，电梯才可以升降。配重4本身的重量是固定不变的，而电梯轿厢这头的重量在电梯空载和满载时变化比较大，为了折中，大部分电梯会将配重的重量设置为电梯半载时的重量。电梯只要不是在平衡状态下升降耗电量都比较大。The driving principle of most elevators is shown in Figure 1, which is driven by motor traction. Its driving principle is as follows: the wire rope 2 is suspended in the rope groove of the traction sheave 3, one end is connected with the car 1, and the other end is connected with the counterweight 4. The traction sheave 3 utilizes the frictional force between it and the wire rope 2 to drive the wire rope 2 and then drive the car 1 to go up and down. But when there is a big difference in the weights on both sides, the traction sheave 3 will give the steel rope 2 a larger frictional force to overcome the gravity difference, so that the elevator can go up and down. The weight of the counterweight 4 itself is fixed, but the weight of the elevator car changes greatly when the elevator is empty and full. In order to compromise, most elevators will set the weight of the counterweight to the half-load the weight of. As long as the elevator is not in a balanced state, the power consumption for lifting and lowering is relatively large.
