A telescopic car door sill and telescopic control method

Abstract

The invention provides a telescopic car-door sill and a flexing control method, belonging to the technical field of elevator sills and solving the problem that a sill is fixed so as to be inconvenient to install. The telescopic car-door sill is characterized in that a driver is a stepper motor, the stepper motor is provided with an angular rotary shaft, a rotary pushing block is arranged on the angular rotary shaft, and the end of the rotary pushing block is movably connected with the bottom of a shielding plate. When a control cabinet sends an angle rotation signal to the stepper motor, the rotary pushing block rotates, and the shielding plate extends out along a pedal slideway or returns to an initial position along the pedal slideway. According to the telescopic car-door sill and the flexing control method, the interval can be largely reduced, even completely eliminated; the structure is simple, so that sundries are prevented from falling down through the interval; the running of the telescopic car-door sill is safe and reliable.

Description

technical field [0001] The invention belongs to the field of elevator sill technology, in particular to a telescopic car door sill and a telescopic control method. Background technique [0002] At present, in the elevator industry, in order to ensure the safe distance for the normal operation of the elevator, there is a gap of about 30 mm between the floor door sill and the car door sill. If the gap is too large, it is easy to cause passengers to feel unsafe when entering the car, and it is easy to get stuck. If the gap is too small, the car will inevitably shake during operation, and there will be risks such as interference and collision; when passengers enter the elevator, debris will easily fall from the gap into the well, causing equipment damage. The existence of the gap between the landing door sill and the car door sill is a hidden danger to the safe operation of the elevator or the safety of passengers. The existing technologies for reducing the gap between the landi...

Problems solved by technology

[0007] The object of the present invention is to address the above-mentioned problems existing in the existing technology, and provide a telescopic car door sill and a telescopic control method. The extension value is consistent with the measured gap distance. When the gap distance of different floors is different, only the difference in the rotation angle signal value can well fill the gap between the landing door sill and the car door sill
