Pit-free elevator energy-saving management system

Abstract

The invention discloses an energy-saving management system for a pit-free elevator, relates to the technical field of automatic control of elevators, and solves the technical problems of energy consumption and intelligent management of the pit-free elevator, a pit of the elevator refers to a hoistway part below the ground of a bottom layer of the elevator, and the pit-free elevator can be directly mounted on a ground finishing surface, so that the energy consumption of the pit-free elevator is reduced. No civil engineering pit needs to be reserved, the strong-drive elevator can be used as a pit-free elevator, the principle of the strong-drive elevator is forced upward pulling type lifting, and therefore in the elevator running process, as long as an internal box does not make contact with the ground, the whole elevator box can be in the stress and energy consumption state all the time, and the whole elevator needs buffering treatment; the invention provides a pit-free type elevator energy-saving management system, and the pit-free type elevator energy-saving management system adjusts an elevator to be in an unmanned state and to be always located at the bottom of an elevator room. The minimum energy consumption of the whole elevator and the minimum abrasion of the whole elevator when the elevator does not run are ensured.

Description

Technical field [0001] The present invention belongs to the field of elevator automatic control technology, involving intelligent energy saving technology, specifically a bottomless pit elevator energy saving management system. Background [0002] The bottom pit of the elevator refers to the shaft part below the ground floor of the elevator, which is used to place buffers, guide rail seats, limiter tension wheels, safety switches, limit switches and other safety devices and other supporting devices such as lighting, intercom and drainage, etc. The bottomless pit elevator can be directly installed on the ground completion surface, without reserving any earthen bottom pit, it is very convenient and very space-saving elevator, suitable for the home environment with limited space, high-rise duplex building installation, the current elevator structure on the market, hydraulic elevator, traction elevator need to reserve the bottom pit, The strong drive elevator can be a pitless elevato...

AI Technical Summary

Problems solved by technology

[0003] The principle of the strong drive elevator is forced upward pull-type lifting, so as long as the inner box does not touch the ground during the operation of the elevator, the entire elevator box will always be in a state of stress and energy consumption, and because of the buffering effect of the bottomless pit , the entire elevator needs to be decelerated and protected when it rises to the top or descends to the bottom during operation. Otherwise, long-term impact and wear will lead to consumption of the box and drag cables, resulting in waste of traction energy.
