Elevator double-side folding car door

Abstract

The invention provides an elevator double-side folding car door, and relates to the field of elevators, the elevator double-side folding car door comprises two groups of folding door bodies in bilateral symmetry and an electric driving system, one sides of the two groups of folding door bodies are hinged to a vertical frame of an elevator car, and when the car door is opened, the electric driving system drives the two groups of folding door bodies to be folded towards the two sides of the elevator car; the width of a portal crane is not larger than that of the elevator car, so that the limited hoistway space can be fully utilized; the folding car door comprises the two groups of folding door bodies which are bilaterally symmetrical, so that the width of one single group of folding door bodies is relatively small, when the folding car door is opened, the two groups of folding door bodies are driven by the electric driving system, a passenger does not need to manually open and close the car door, the extension range of the single group of folding door bodies is located in two side areas in the elevator car, the extension range is small, and therefore, the riding comfort is effectively improved.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator double-side folding car door. Background technique [0002] Most of the existing elevator car door opening methods are side-opening automatic doors and center-opening automatic doors. However, the traditional elevator car doors occupy the space of the well, and the width of the door machine is greater than the width of the car. The size of the hoistway of the elevator is required to be smaller and smaller, resulting in a smaller car volume, which makes it difficult to make full use of the hoistway space. [0003] In order to partially solve this technical problem, the patent publication number CN205099170U, the patent name is a double-leaf manual folding car door device for an elevator, the invention patent discloses a double-leaf manual folding car door device for an elevator, including a car door, a car door It consists of side-by-side hanging wheel doors and hinged hinged...

[0002] Most of the existing elevator car door opening methods are side-opening automatic doors and center-opening automatic doors. However, the traditional elevator car doors occupy the space of the well, and the width of the door machine is greater than the width of the car. The size of the hoistway of the elevator is required to be smaller and smaller, resulting in a smaller car volume and it is difficult to make full use of the hoistway space

[0003] In order to partially solve this technical problem, the patent publication number CN205099170U, the patent name is a double-leaf manual folding car door device for an elevator, the invention patent discloses a double-leaf manual folding car door device for an elevator, including a car door, a car door It consists of side-by-side hanging wheel doors and hinged hinged doors. There is a door hanging rail at the upper end of the car entrance and exit. The upper end of the outer side of the rotating shaft door is rotatably connected with the door hanging rail through the upper door shaft. The lower end of the outer side of the rotating shaft door is connected with the lower door shaft The sill chute is rotationally connected, the upper end of the outer side of the hanging wheel door is fixed with a door hanging wheel, the lower end of the outer side of the hanging wheel door is fixed with a guide shaft, the bottom end of the front side of the door head beam is installed with an electromagnetic lock and a door close verification switch, and the upper end of the rotating shaft door is An electromagnetic lock suction plate is installed on the front side. After the door is fully closed, the door close verification switch is turned on, the electromagnetic lock and the electromagnetic lock suction plate are attracted, and the safety circuit of the elevator is connected. Manually opening and closing the car door, and only being able to fold the car door on one side, is not only unsafe, but also the car door needs to be folded and extended to a large area in the car during the folding process, which makes the car with limited space more crowded and the experience is poor
