Problems solved by technology

[0004] 1. When the elevator is on the leveling floor, the parking position of the car depends entirely on the brake of the main engine of the elevator. When passengers enter and exit the elevator, if the brake is opened, the wire rope is pulled by the torque of the main engine. If the torque is insufficient and the car reverses, the car will will roll away, very dangerous
[0005] 2. If the fret...

Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0025] like Figure 1 ~ Figure 3 As shown, a device for aligning the car door sill with the landing door sill includes a bracket, a motor support 4, an ultrasonic motor 3, a micro-moving platform 6, a spring 7 and a position sensor 11; the bracket 2 is rigidly connected Or it is detachably connected to the top of the upper car bottom 1, and the motor support 4 is rigidly connected through the bracket 2 or is detachably connected. The cross section of the bracket 2 is C-shaped, which is used to support the motor support 4. , so that the ultrasonic motor 3 is not in contact with the upper car bottom 1 all the time, the motor support frame has 4 large holes and 16 small holes, 4 larg...

Abstract

The invention discloses a device enabling a car door sill to align at a landing door sill. A bracket is connected to the upper portion of an upper car platform in a rigid or detachable mode and connected with a motor support in a rigid or detachable mode; one or more ultrasonic motors are fixedly connected to the motor support respectively; main shafts of the ultrasonic motors are connected with a micro-positioning platform connected to a car floor through one or more springs; a position sensor is arranged on the side of the car door sill and electrically connected with the ultrasonic motors. The relative position precision of the car door sill and the landing door sill is higher; influences caused by insufficient micro-positioning platform layer precision and faults can be eliminated; through fine motion of a car, a car frame is fixed, a main machine brake does not need to be released in the platform layer, and safety when a door is opened in an elevator leveling area; a few transmission chains are provided for the device; the system response is rapid; the transmission precision is high, working efficiency is high, interference is low, and the signal attenuation rate is low.

Description

technical field [0001] The invention relates to a device for aligning a car door sill with a landing door sill. Background technique [0002] In today's elevators, with the continuous rise of the floor, the total length of the wire rope connecting the elevator traction host and the car continues to increase, and the elongation of the wire rope is proportional to its total length. When the elevator is on a leveling floor, as the number of passengers increases, the bottom of the car will move down, causing the car door sill and the landing door sill to be out of alignment, causing inconvenience to people entering the elevator, and even tripping. [0003] The realization of the existing automatic leveling function is generally: induction leveling through the magnetic isolation plate, and position detector detection. When the moving distance of the car exceeds the specified value, the control system controls the main engine to open the brake, the main engine rotates, and lifts ...
