Elevator driving system based on electric chassis

Abstract

The invention relates to the field of elevator control, and provides an elevator driving system based on an electric chassis. The system comprises an electric chassis, a lift car and a guide wheel. The electric chassis and the lift car are connected through a traction rope wound around the guide wheel 3. The guide wheel is arranged at the top of an elevator shaft; the electric chassis and the lift car are arranged in the shaft; and electromechanical equipment arranged in the electric chassis, the guide wheel, a diversion sheave arranged on the lift car and the traction rope form an elevator traction output system to output and transmit power, and when the electromechanical equipment arranged in the electric chassis runs, the lift car and the electric chassis run up and down in the shaft. A traction machine and an energy storage battery are arranged on the counterweight side of a traditional elevator, so that the elevator runs away from a power grid, potential energy recovery is achieved, meanwhile, the peak load shifting function of the power grid is achieved, and the elevator has the advantages of energy conservation, emission reduction, safety and reliability.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to an elevator driving system based on an electric chassis. Background technique [0002] At present, elevators have become an indispensable means of transportation in people's daily life. There are many types of elevators, but their composition and operating principles are similar, such as figure 1 as shown, figure 1 Structural diagram of elevator traction principle. figure 1 In the elevator traction principle shown, the elevator includes a traction machine, a guide wheel, a car and a counterweight, and the car and the counterweight are connected by a wire rope passing through the traction machine runner and guide wheels, and the traction machine Driven by the drive to drive the operation of the wire rope to control the operation of the elevator car. [0003] The existing elevator basically adopts a traction structure. In order to reduce the power of the motor, a count...

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the huge energy consumption of the elevator existing in the operation of the existing elevator, the elevator needs to drag the heavy object to move vertically, and a lot of energy is converted into the potential energy of the heavy object, which consumes a lot of energy, and, The recyclable energy of the elevator is wasted when it runs up and down; most elevators run during the day, and there is no peak period of electricity consumption during the operation period, and the electricity price is high, so the power consumption in the valley cannot be well utilized; the control box for controlling the operation of the elevator needs to be set separately. The problem of taking up space
