Abstract

The invention provides an elevator re-leveling method and an elevator re-leveling system. The elevator re-leveling system comprises an elevator main control module, a leveling position detection device, a motor, a screw rod and a slide rod; the screw rod is in threaded connection with the slide rod; the top of the slide rod jacks the bottom of an elevator car; the elevator leveling position detection device is used for detecting a distance between the elevator car and a landing door sill; when an elevator is leveled and the distance between the elevator car and the landing door sill is detected to be changed, a distance change signal is sent to the elevator main control module; after receiving the distance change signal, the elevator main control module sends a starting signal to the motor; and the motor is started, drives the screw rod to rotate, and the slide rod is lifted or lowered. According to the elevator re-leveling method and the elevator re-leveling system, the elevator car re-leveling is accurate and safe.

Description

Elevator re-flatting method and system
Technical field
The present invention relates to the again method and system of flat bed of a kind of elevator.
Background technology
Along with the lasting intensification of urbanization process, increasing skyscraper begins to rise sheer from level ground in the city, and the space in city constantly extends to vertical direction, and floor is more and more higher.Yet floor is higher, and the steel rope total length that main frame links to each other with car in the elevator is just longer.Steel rope has stroke, and the steel rope stroke of unit length is certain, and steel rope is longer, and final total deformation quantity is just larger.Like this, when elevator is in flat bed, increase along with the patronage that enters car, lift car will move down, the car bottom of this moment and lading door dill be not at same plane, the passenger who advanced again afterwards car obviously feels to step on empty sense, the safety problems such as serious meeting causes falling, tumble injury when entering elevator.Automatic again story-leveling function after lift car moves down becomes the method that addresses this problem.
Existing automatically again the realization of story-leveling function generally be: after car moved down distance and exceeds specified value, the control system main control system was opened band-type brake, and main frame rotates, and car is promoted, and makes car reach again the purpose of flat bed.But, there is very large potential safety hazard in this scheme, elevator is when flat bed, and by the band-type brake of elevator main, the passenger is passing in and out the off-position of car entirely, if this moment, band-type brake was opened, complete in main frame torque pulling steel rope, just in case moment is inadequate, the situations such as reversing appear, car can glide suddenly, and danger is very large.
Summary of the invention
The purpose of this invention is to provide a kind of elevator re-flatting method and system, lift car is leveling accuracy, safety again.
In order to solve the problems of the technologies described above, elevator re-flatting method provided by the invention and system are achieved in that
A kind of elevator is the flat bed system again, comprising: elevator main control module, level position detecting device, motor, screw rod and slide bar; Described screw rod is connected with described slide bar silk, and the lift car bottom is withstood at described slide bar top; Described level position of elevator detecting device is for detection of the distance of lift car and lading door dill, when Elevator landing, when detection lift car and lading door dill distance change, to elevator main control module transmission range variable signal; Described elevator main control module after receiving described variable in distance signal, sends the signal that starts to described motor; Described electric motor starting drives described bolt rotary, and described slide bar raises or reduces.
Optionally, described motor is connected with described screw rod tooth.
Optionally, described level position detecting device is installed between car and the guide rail or between car and the lading door dill.
Optionally, described level position detecting device is magnetic induction or photoelectric induction device.
Optionally, described elevator again flat bed system also comprises: screw bolt support, described screw rod is connected by bearing with described screw bolt support.
The present invention also provides a kind of elevator re-flatting method, comprising: when the distance of detection lift car and lading door dill changes, to elevator main control board transmission range variable signal; Described elevator main control board sends actuation signal to motor, and electric motor starting drives bolt rotary, and two point of connection on the bolt rotary band moving slide-bar are along described screw rod sway.
Optionally, described motor is connected with described screw gear.
The present invention also provides again leveling device of a kind of elevator, comprising: screw rod, slide bar and motor; Described motor be connected screw gear and connect, described screw rod be connected the slide bar silk and connect.
Optionally, also comprise: screw bolt support, described screw rod is connected by bearing with described screw bolt support.
Elevator provided by the invention is the flat bed system again, when Elevator landing, when detection lift car and lading door dill distance change, to elevator main control module transmission range variable signal; Described elevator main control module after receiving described variable in distance signal, sends the signal that starts to described motor; Described electric motor starting drives described bolt rotary, and described slide bar raises or reduces.Is connected by silk between screw rod and the slide bar, with respect to the elevator of prior art flat bed again, elevator of the present invention again flat bed is safe, accurately and reliably.
