Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator technology, and in particular to an elevator landing door buffer anti-collision device. Background Technology
[0002] Elevator landing doors are a crucial safety barrier in elevator systems, primarily fulfilling three core functions: 1) Safety isolation: As the only physical barrier between floors in the elevator shaft, landing doors completely separate the shaft from the waiting hall when closed, effectively preventing people or objects from accidentally falling into the shaft and avoiding falls from heights. 2) Operational interlocking control: Landing doors achieve double interlocking through mechanical door locks and electrical safety devices. Only when the landing door is fully closed and the mechanical lock hook is engaged will the electrical contacts connect the elevator control circuit, allowing the elevator to start running; if not fully locked, the elevator will automatically stop. 3) Dynamic coordinated operation: Landing doors have no power system of their own; their opening and closing are driven by the car door through a linkage mechanism. When the elevator stops, the precise movement of the car door triggers the landing door to open synchronously, forming a continuous entry and exit passage; when closing, both doors reset in tandem, ensuring passage efficiency and shaft sealing. In addition, landing doors also function as fire compartments in buildings and are equipped with sensors such as light curtains and safety touch panels. Therefore, the landing doors are not only the "gatekeepers" of elevator safety, but also the core dividing interface between the elevator riding environment and the dangerous areas of the shaft.
[0003] Existing elevator landing door buffer and anti-collision devices have shortcomings in use. First, they cannot provide buffer and anti-collision when two landing doors are joined together; second, their function is limited and cannot improve the displacement stability of the landing doors. Therefore, it is necessary to optimize and improve the existing elevator landing door buffer and anti-collision devices. Summary of the Invention
[0004] The purpose of this utility model is to overcome the above-mentioned problems existing in the traditional technology and to provide an elevator landing door buffer anti-collision device.
[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: An elevator landing door buffer and anti-collision device is provided, which is installed between the inner side of the frame and the inner side of the landing door. The device includes a fixed rail frame, a movable rail frame, a scissor-lift telescopic frame, a buffer anti-collision pad, and an anti-detachment rod. The fixed rail frame is fixed to the inner side of the frame, the movable rail frame is fixed to the inner side of the landing door, the scissor-lift telescopic frame is installed between the fixed rail frame and the movable rail frame, a buffer anti-collision pad is installed on the outer side of the movable rail frame, an anti-detachment rod is installed in the middle of the scissor-lift telescopic frame, and an anti-detachment groove parallel to the displacement direction of the landing door is formed on the inner side of the frame. The outer end of the anti-detachment rod slides and is restricted within the anti-detachment groove.
[0006] Furthermore, in the aforementioned elevator landing door buffer and anti-collision device, a horizontal slide rail is installed on the inner top of the frame, and a suspension member that slides and is restricted on the horizontal slide rail is installed on the inner top of the landing door.
[0007] Furthermore, in the aforementioned elevator landing door buffer anti-collision device, a protrusion is provided at the bottom inner side of the frame, a horizontal rolling groove is provided on the upper side of the protrusion, and a support roller capable of rolling along the horizontal rolling groove is installed at the bottom of the landing door.
[0008] Furthermore, in the aforementioned elevator landing door buffer anti-collision device, both the fixed rail frame and the movable rail frame are vertical rail frames, and each of the fixed rail frame and the movable rail frame is symmetrically provided with vertical sliding grooves to facilitate the displacement of the ends of the scissor lift telescopic frame.
[0009] Furthermore, in the aforementioned elevator landing door buffer anti-collision device, the outer end faces of the fixed rail frame and the movable rail frame are flush with each other.
[0010] Furthermore, in the aforementioned elevator landing door buffer anti-collision device, when two landing doors approach each other, the two opposing buffer anti-collision pads can abut against each other before the landing doors come into contact.
[0011] The beneficial effects of this utility model are: 1. Features double-door docking buffer and anti-collision function: This solves the problem that existing devices cannot provide buffer and anti-collision when two doors dock.
[0012] 2. Improve the stability of door displacement: Overcome the shortcomings of existing devices that are single-function and cannot improve the stability of door displacement.
[0013] 3. Reasonable structure and reliable operation: Through the coordinated action of multiple components, the stability and safety of the elevator landing doors are ensured during operation.

An anti-detachment rod 12 is installed in the middle of the scissor lift frame 10, and an anti-detachment groove 13 parallel to the displacement direction of the landing door 2 is opened on the inner side of the frame 1. The outer end of the anti-detachment rod 12 is limited to sliding within the anti-detachment groove 13.
[0019] In this embodiment, a horizontal slide rail 3 is installed on the inner top of the frame 1, and a suspension piece 4 that slides and is restricted on the horizontal slide rail 3 is installed on the inner top of the door 2.
[0020] In this embodiment, a protrusion 5 is provided at the bottom inner side of the frame 1, and a horizontal rolling groove 6 is provided on the upper side of the protrusion 5. A support roller 7 capable of rolling along the horizontal rolling groove 6 is installed at the bottom of the door 2.

[0022] In this embodiment, the outer end faces of the fixed rail frame 8 and the movable rail frame 9 are flush with each other.
[0023] In this embodiment, the outer end of the anti-detachment rod 12 is a T-shaped head, and the vertical cross-section of the anti-detachment groove 13 is a T-shaped groove that is narrow on the outside and wide on the inside.
[0024] In this embodiment, when the two floor doors 2 approach each other, the two opposing buffer anti-collision pads 11 can abut against each other before the floor doors 2 come into contact with each other.
[0025] The working principle of this embodiment is as follows: Overall structural layout: The elevator landing door buffer anti-collision device is set between the inner side of the frame 1 and the inner side of the landing door 2, and consists of components such as fixed rail frame 8, movable rail frame 9, scissor telescopic frame 10, buffer anti-collision pad 11 and anti-detachment bar 12.
[0026] Top guidance and support for the landing door: A horizontal slide rail 3 is installed on the inner top of the frame 1, and a hanging part 4 is installed on the inner top of the landing door 2. The sliding of the hanging part 4 is restricted on the horizontal slide rail 3, providing guidance and support for the top of the landing door 2, so that the landing door 2 can move smoothly in the horizontal direction.
