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

Abstract

The embodiment of 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 and first driving guide assemblies. The car door electric driving assembly is arranged at the top of a lift car body and used for providing driving power for the first driving guide assemblies. The two sets of first driving guide assemblies are arranged, a left car door and a right car door are arranged on the lift car body through the corresponding first driving guide assemblies, and the first driving guide assemblies on the two sides of the car door electric driving assembly are connected and used for driving the left car door and the right car door to rotate in the door opening direction or the door closing direction. The car door opening and closing control mechanism, the landing door opening and closing control mechanism and the door system, the large door opening width can be achieved under the condition that the well width is small, the effective utilization rate of the cross section of a well is increased, therefore the purpose that the cross section size of the well is reduced under the condition that the cross section of a lift car is the same is achieved, and meanwhile passengers can open a door manually to complete self rescue after the lift car is leveled during rescue.

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. [0003] In addition, the traditional split door cannot realize multi-directional simultaneous door opening. Contents of the invention [0004] In...

Problems solved by technology

[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 door leaf width, and the utilization rate of the cross-sectional width of the shaft is low. When the cross-sectional width of the shaft is small, a large door opening width cannot be realized. , the conventional split door can not realize the self-rescue of the "stuck ladder" when the passenger manually opens the door in the car, which is not conducive to the realization of the passenger's self-rescue

[0003] In addition, the traditional split door cannot realize multi-directional simultaneous door opening
