A safe and energy-saving intelligent elevator

Abstract

The invention discloses a safe energy-saving intelligent elevator, comprising a lift car, a door system, a guide rail, a balance system, an overload limit device and a control system which are located in a shaftway; the lift car comprises a car body and a lift car frame, and the door system comprises a lift car door and a layer door; door stop devices are arranged on both upper and lower ends of the two sides of the lift car door, each door stop device comprises a fixing component and a door stop component, the balance system comprises a counterweight and placing grooves arranged in two sides of the guide rail, and the counterweight is connected on the top of the lift car by a dragging steel rope and can move up and down along the guide rail. The door stop devices are arranged on the upper and lower ends of two sides of the lift car door, when the lift car door is opened, a spring drives an inner rod to extend to a direction vertical to the lift car door so as to block the lift car door, such that entering and exiting safety of taking personnel is ensured; a total weight of the counterweight is changed by second electric push rods and a bidirectional push rod, such that the elevator lift car and the counterweight are kept balanced all the time, and further the up and down operation safety of the elevator is ensured.

Description

Technical field [0001] The invention relates to the field of elevators, in particular to a safe and energy-saving intelligent elevator. Background technique [0002] Elevator refers to a permanent transportation equipment that serves several specific floors in a building, and its car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or whose inclination angle to the plumb line is less than 15°. There is also a stepped type, the stepper is installed on the track to run continuously, commonly known as an escalator or moving walk. Fixed lifting equipment serving the specified floors. The vertical elevator has a car that runs between at least two rows of vertical or rigid guide rails with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload cargo. It is customary to regard elevators as the general term for vertical transportation vehicles in buildings regard...

AI Technical Summary

Problems solved by technology

In order to prevent the elevator from trapping people when closing the door, there is a door closing safety device on the car door. Common anti-pinch safety devices include safety touch panels, infrared light curtains and ultrasonic monitoring devices. Infrared and ultrasonic signals are easily affected by external signals. Interference can easily lead to the loss of control of the anti-pinch safety device, and it still cannot effectively prevent people from being trapped by the elevator door; moreover, the counterweight of the existing elevator is fixed, and the counterweight is balanced with the maximum weight carried by the elevator car, resulting in a serious waste of power consumption
