Variable counterweight elevator and variable counterweight hydraulic elevator

Abstract

The invention discloses a variable counterweight elevator and a variable counterweight hydraulic elevator and is designed for solving the problems of counterweight balance, high energy consumption and the like of the conventional elevator. The variable counterweight elevator comprises a traction electromotor, an elevator box arranged in an elevator well, a pulley block, a counterweight and a traction rope which connects the elevator box and the counterweight and passes through the pulley block, wherein the counterweight consists of at least two counter weight blocks; at least one group of counter weight adjusting manipulators are fixedly arranged in the elevator well; and control instrument input ends of the counter weight adjusting manipulators are connected with a control device which controls the counter weight adjusting manipulators to be clamped with the counter weight blocks. The variable counterweight elevator and the variable counterweight hydraulic elevator can correspondingly change the weight of the counterweight according to the weight of passengers and goods in the elevator box and have low electric power consumption.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator and a hydraulic elevator capable of realizing variable counterweight during use. Background technique [0002] Traditional elevators are equipped with a constant mass balance counterweight. But in the actual operation process, the sum of the weight of the car and the mass of passengers and goods is not constant. Since the weight of the car and the mass of the passengers and cargo are constantly changing, when the motor operates the car, the motor consumes a large amount of power to correspond to the variable weight. For example: when the car rises from a low position to a high position, if the total weight of the car and the passengers and goods inside is greater than the counterweight, the excess weight will consume electric energy; if the total weight of the car and the passengers and goods inside When it is less than the counterweight, the high potential energy of the ex...

Problems solved by technology

For example: when the car rises from a low position to a high position, if the total weight of the car and the passengers and goods inside is greater than the counterweight, the excess weight will consume electric energy; if the total weight of the car and the passengers and goods inside When it is less than the counterweight, the high potential energy of the excess weight of the counterweight will be wasted
