Embodiment Construction

[0033] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0034] Such as figure 1As shown, a control device for the leveling position of an elevator, the elevator includes a shaft 10 and a car 20 positioned in the shaft 10, a driving device (not marked in the drawings) that drives the car 20 to move, the control device for the leveling position of the elevator It includes at least one distance measuring sensor 30 located at the top or bottom of the hoistway 10, a baffle 40 opposite to the distance measuring sensor 30, and a control system (not marked) electrically connected to the distance measuring sensor 30. The baffle is fixed on the car On the compartment 20, the control system is electrically connected with the driving device.

[0035] The ranging sensor 30 is fixed on the top or bottom of the hoistway 10, and cooperates with the baffle plate fixed on the car 20, so the installation and debugging are convenient...

Abstract

The invention relates to a control device and method of the elevator flat floor position. An elevator comprises a shaft, an elevator car, and a drive device driving the elevator car to move, and the elevator car and the drive device are arranged in the shaft. The control device of the elevator flat floor position comprises at least one ranging sensor arranged on the top or bottom of the shaft, baffles opposite to the ranging sensors, and a control system electrically connected with the ranging sensors. The baffles are fixed to the elevator car. The control system is electrically connected with the drive device. The ranging sensors are fixed to the shaft and matched with the baffles fixed to the elevator car. Thus, installing and adjusting are convenient, the installing convenience is improved, the production efficiency is high, and the installing progress of the elevator project is guaranteed. The real-time and accurate measurement is carried out on the position distance of the elevator car through the ranging sensors, the running of the elevator car is controlled through the control system, and the problem that the longer running time of the elevator is, the larger the generated flat floor error becomes is solved. The running of the elevator is safer, and the accuracy of the elevator flat floor position is guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a control device and method for elevator leveling positions. Background technique [0002] With the continuous increase of urban population and the rapid development of urban construction, high-rise buildings have become the main body of contemporary urban buildings, and the application of elevators is becoming more and more extensive. At present, each floor of the elevator leveling floor is equipped with a magnetic isolation board. When the position detector installed on the car frame passes through the magnetic isolation board, it will issue an instruction to reduce the speed of the elevator and stop it, so as to achieve the effect of leveling. The elevator needs to operate according to the speed and distance feedback of the encoder on the motor side, combined with the position information of the position detector in the hoistway and the magnetic isolation plate. When the ele...
