Abstract

The invention discloses an automatic balance weight adjusting type energy-saving elevator which comprises an elevator shaft, an elevator car and a traction machine, the elevator car and the traction machine are arranged in the elevator shaft, the traction machine is arranged at the top of the elevator shaft, a traction rope is installed on the traction machine, one end of the traction rope is connected with the top of the elevator car, and the other end of the traction rope is connected with the elevator car. The other end of the hoisting rope is connected with an elevator balance weight, the elevator balance weight comprises a balance weight shell, a containing cavity is formed in the balance weight shell, the containing cavity is connected with an automatic liquid filling and taking system, and the elevator further comprises a controller and a weighing sensor. Total mass data signals of the elevator car are fed back to the controller through the weighing sensor, the controller controls the hydraulic pump to input or extract fluid out of the balance weight according to the balance principle, the weight of the balance weight and the weight of the car are made to be consistent, and therefore the power consumption of the traction machine is reduced, and the energy-saving purpose is achieved.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to an energy-saving elevator with automatic counterweight adjustment. Background technique [0002] The elevator has a car and a counterweight, which are connected by a traction rope (wire rope), and the traction rope (wire rope) is driven by the traction of the drive device (traction machine) to make the elevator car and the counterweight in the hoistway Do up and down motion on the guide rail. The operation of the elevator mainly depends on the friction between the traction wheel groove and the traction rope. In order to make the car and the counterweight reach a relative balance when the elevator is running, the weight of the counterweight is usually equal to the weight of the car + (40% to 50%, usually The value is 45%). When the weight of the elevator car and the elevator counterweight are the same, the traction machine does the least work and consumes the least power. When ...
