Problems solved by technology

When the generator motor is in the power generation state, the power generation of the generator motor is proportional to the rotation speed. However, when the elevator is running, the running speed of the car is low and the speed of the generator motor is low. Therefore, the power generation of the generator motor is relatively low. Less, can not make good use of the gravity potential energy of the elevator

Abstract

The invention belongs to the field of elevators, and particularly discloses an elevator electric generating device. The elevator electric generating device comprises a car hoistway, a support frame, a pulling force sensor, a single-chip microcomputer and an electric generating part, wherein the support frame is fixed above the car hoistway; the pulling force sensor is arranged between a car and a steel rope; the single-chip microcomputer and the electric generating part are electrically connected with the pulling force sensor; a step motor electrically connected with the single-chip microcomputer is arranged on the support frame, and a first gear is arranged on the step motor; a connecting rod in sliding connection with the support frame is arranged on the support frame, and a first rack meshed with the first gear is arranged on the connecting rod; the electric generating part comprises a gear rack positioned on the right side of the car hoistway, a generator fixed on the right side of the car, and an accumulator electrically connected with the generator; the top end of the gear rack is fixedly connected with the connecting rod, and a sliding block is arranged at the lower end of the gear rack; a sliding chute matched with the sliding block is formed in the bottom of the car hoistway. The invention aims to provide the elevator electric generating device which can enable the electric generating efficiency of an elevator under an electricity generation state to be improved.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator self-generating device. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. Elevators are now widely used in high-rise buildings in cities to provide people with a more convenient life. [0003] The elevator generally includes a car, a counterweight, a steel wire rope and a traction wheel. The car and the counterweight are respectively located on both sides of the traction wheel. The height of the car and the counterweight is changed by the traction of the traction wheel, which not only changes the gravitational potential energy of the car and the counterweight, but also realizes the normal operation of the elevator. The weight of the counterweight is generally equal to half of the full load weight of the car, so the motor po...
