Car door opening and closing control mechanism, landing door opening and closing control mechanism and door system

Abstract

The invention discloses a car door opening and closing control mechanism, a landing door opening and closing control mechanism, and a door system. The car door opening and closing control mechanism comprises a car door electric driving assembly, a driving belt and a driving guide assembly; the car door electric driving assembly is arranged on the car door through a car door upper guide rail and used for providing driving power for the driving belt; the driving belt is wound on the car door electric driving assembly and used for driving the driving guide assembly and a left car door to move inthe door opening direction or the door closing direction under the action of the car door electric driving assembly; and the driving guide assembly is arranged on the driving belt and used for movingin the door opening direction or the door closing direction to lock, close or open a right car door. The large door opening width can be achieved under the condition of the small shaft width, so thatthe effective utilization rate of the cross section of a shaft is increased, the purpose of reducing the cross section size of the shaft under the condition of the same lift car cross section is achieved, and meanwhile, passengers can manually open a door to complete self-rescue after the car is leveled during difficulty relieving.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a car door opening and closing control mechanism, a hall door opening and closing control mechanism and a door system. Background technique [0002] The conventional center split door leaf is an integral structure, and the left and right leaves move in a straight line. The shaft needs nearly twice the width of the door leaf, and the utilization rate of the cross-sectional width of the shaft is low. In the case of a small cross-sectional width of the shaft, a large door opening width cannot be realized. , the conventional middle split door cannot realize the self-rescue of the "trapped ladder" when the passenger manually opens the door in the car, which is not conducive to the realization of the passenger's self-rescue. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a car door opening and closing control ...
