Description
Technical field
The utility model relates to the elevator technology field, relates in particular to the elevator car position that a kind of locating speed is fast, simple in structure, cost is low and confirms device.
Background technology
Normal operation has very important meaning to elevator car position for elevator.At present, using is to utilize rotary encoder to realize the affirmation of elevator car position more widely.When elevator owing to when anxious stopping, taking place between system cut-off or hoist ropes and the traction sheave situation such as slippage and causing elevator position to be lost, elevator is carried out the position be confirmed to be necessary again, otherwise elevator can't normally move.
At present, more common car position confirmation method again is to make elevator run to the end station location, with the key horizon of end station location as elevator.
It is the Chinese patent application of CN1491878A for the Chinese utility model patent of CN202046769U, Granted publication number for the Chinese invention patent of CN201062178Y, publication number that some patents such as Granted publication number are also arranged, these patents have proposed each floor of elevator hoistways is encoded, confirm the position of lift car then by the coded message that detects respective storey, but each floor of elevator hoistways is carried out Methods for Coding need increase a large amount of detected materials or detector, increase the work capacity of elevator Installation and Debugging, also increased the cost of elevator simultaneously.
Also having some patents in addition, is the Chinese patent application of CN102344063A as publication number, has proposed at velocity limiter the absolute type encoder system to be installed, and that utilizes speed limiter wire rope and car captives joint to confirm elevator car position.But the method that the absolute type encoder system is installed at velocity limiter need increase an absolute type encoder on the basis of existing elevator device, and its cost is higher relatively; And when elevator cuts off the power supply, the function of coder will lose efficacy.
Summary of the invention
