Automatic balance weight energy-saving control system for elevator

Abstract

The invention relates to an automatic balance weight energy-saving control system for an elevator. A control mechanism is connected with a pressure sensor. The pressure sensor is located at the lower portion of a bottom plate of an elevator car. When an elevator door is closed, the elevator is electrified to enter a working state. Pressure data signals of the pressure sensor are transmitted to the control mechanism. The control mechanism receives the data of the pressure sensor. Balance weight assemblies are matched with an eight-claw hook so that a give balance weight value given by the control mechanism is selected; and the elevator car is connected with a motor and a clutch through a traction steel rope, and the motor, the clutch and a fixed balance weight are connected with the eight-claw hook through a traction steel rope. An electric storing device is connected with the control mechanism. The control system selects the balance weight assembly with the matched weight through cooperation of an automatic balance weight device and the control mechanism, the mass difference between the elevator car and the balance weight is reduced, and the variable balance weight is effectively achieved; and the balance weight assembly is used for achieving mutual conversion of gravitational potential energy in the elevator running process, and electric energy consumption is reduced on the basis that stable operation of the elevator is guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevator control and application, in particular to an elevator automatic counterweight energy-saving control system. Background technique [0002] With the development of construction technology and the acceleration of urbanization, elevators in high-rise buildings have become an indispensable means of transportation in people's daily life. At present, during the operation of the elevator, the motor is powered by the grid to convert the electric energy into kinetic energy to drive the elevator car to run. When the elevator car goes up with no load or goes down with a full load, the elevator system converts the potential energy into electric energy through the motor, but Some energy is wasted in the process. [0003] In the patent CN103787160A, "an environmental protection and energy-saving elevator control device and its method" are disclosed. The control device and its method determine whether the eleva...

Although this "shared ride concept" and "energy-saving method" are suitable for commuting time, that is, full load up or full load down, they cannot meet the needs of passengers' lives and work efficiency in an emergency

In real life, the number of floors of office buildings or high-rise apartments in big cities is usually higher than 15 floors. Most people, especially the elderly, are inconvenient to climb the stairs. The starting value of the number of people, this energy-saving method undoubtedly delays the use of demanders, reduces work efficiency, and the experience is not good, thus affecting the market demand and application prospects of this energy-saving elevator
