Problems solved by technology

Therefore, most of the elevator systems currently on the market do not have corresponding protective measures to prevent the car from slipping. Even if a small number of elevator systems involve protective measures to prevent the car from slipping, the measures are basically passed It is realized by pure electrical control, such as installing a travel switch at each floor of the elevator shaft, or by adding an encoder to convert the linear displacement of the car into an electrical signal and send it to the electrical control system of the elevator. The electrical control system is used to judge whether the car is slipping, so as to drive the elevator car emergency braking device such as the rope clamp or / and safety gear to forcibly brake the running car
However, the pure electrical control method for preventing car slippage mentioned above has technical defects of poor application stability.

Abstract

The invention discloses a method for safe operation of a car elevator, in particular to a method for leveling and anti-slipping of a car elevator. Car emergency braking device, in which the sheave and / or sheave lead-out device operates synchronously with the elevator car, when the elevator car enters the leveling floor and stops, the elevator car is monitored in real time through the sheave and / or sheave lead-out device When the elevator car slips, the above-mentioned sheave and / or the pull-out device of the sheave will rotate synchronously, and the emergency braking device of the elevator car will be controlled to perform emergency braking by the amount of rotation displacement, thereby It solves the technical problem of preventing the elevator car from slipping when it is parked on the level floor, improves the operation stability of the car-elevator system, reduces the possibility of potential safety hazards during the operation of the car-elevator, and ensures the life and property of the passengers Safety.

Description

technical field [0001] The invention relates to a method for safe operation of an elevator, in particular to a method for preventing slippage on a leveling floor of an elevator. At the same time, the present invention also provides a device used in the above-mentioned elevator leveling anti-slip method. Background technique [0002] The principle of the elevator is a pulley block, and the two ends of the pulley are hung with the car and the counterweight by steel wire ropes. The use of the elevator relies on the motor to drive the traction sheave to rotate, which drives the wire rope to move, thereby driving the position of the car and the counterweight to change. [0003] Among them, the movement of the above-mentioned steel wire rope is transmitted by the frictional force between the traction sheave and the steel wire rope. This frictional force is the traction force, and its magnitude is affected by factors such as the shape of the traction sheave groove and the thicknes...
