Description

Technical Field

[0001] This invention belongs to the field of elevator shaft construction safety protection technology, and more specifically, relates to an integrated elevator shaft protection system and method. Background Technology

[0002] During building construction, elevator openings and shafts require protection to ensure safety and ease of construction. Elevator opening protection typically uses traditional fence-style or steel pipe railings anchored to the wall. Elevator shaft protection usually employs ground-mounted scaffolding, erected sequentially from bottom to top. The independent protection of horizontal and vertical elevator shaft openings is unsatisfactory in terms of construction time, cost, and safety, and subsequent dismantling is relatively troublesome. This is especially true for tall buildings, where elevator shaft protection requires extensive scaffolding erection, which is not only time-consuming and labor-intensive but also prone to instability.

[0003] While existing elevator shaft safety devices can be stably fixed to the wall, they lack horizontal opening protection, posing a risk of falling objects from height. Furthermore, the longitudinal members of existing elevator shaft safety devices are fixed and cannot be adjusted according to the size of the opening, and horizontal protection requires construction work within the elevator shaft, creating a risk of working at height.

[0004] Although some existing elevator shaft protection devices are movable, the protrusions on the top of the movable elevator shaft protection devices can easily cause secondary injuries in an accident, and the movable elevator shaft protection devices are also inconvenient to dismantle later. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides an integrated elevator shaft protection system and method. This system integrates protective doors and panels, effectively preventing construction personnel and equipment from accidentally entering the elevator shaft and significantly reducing the risk of safety accidents. The invention features a simple structure, modular design, and ease of installation and disassembly, improving construction efficiency. It solves the problems of low construction efficiency, instability, and inadequate early warning systems for high-altitude operations associated with existing protection methods. Furthermore, this invention is low-cost, has a long service life, and is easy to maintain and manage.

[0088] After all installations are completed, a comprehensive inspection is conducted to ensure that all components are installed correctly and securely; the motor 6 and rack telescopic mechanism 9 are tested to ensure that the protective plate can be smoothly extended and retracted; the gravity sensor is tested to ensure that it can accurately monitor the safety status of the elevator shaft.

[0089] This invention provides an integrated elevator shaft protection system and method. A protective door 2 is installed at the vertical opening 1 of the elevator shaft using a strong magnetic clamp 8. A retractable horizontal protective device 3 is connected to the bottom of the protective door 2 via a first hinge 5 and a hydraulic strut 4, forming a single unit with the protective door 2, thus achieving safety protection at the elevator shaft opening. A motor 6 controls the hydraulic strut 4 and the first hinge 5 to push the retractable horizontal protective device 3 into the elevator shaft, causing it to cantilever within the shaft. The motor 6 drives the outer horizontal protective component 31 and the inner horizontal protective component 33 to slide back-to-back at the front and rear ends of the intermediate horizontal protective component 32, achieving the connection between the outer horizontal protective component 31 and the intermediate horizontal protective component 32. 2. The inner horizontal protective component 33 is laid longitudinally within the horizontal opening of the elevator shaft; the hinges on the outer horizontal protective component 31, the middle horizontal protective component 32, and the inner horizontal protective component 33 are opened by the motor 6, realizing the lateral laying of the outer horizontal protective component 31, the middle horizontal protective component 32, and the inner horizontal protective component 33 within the horizontal opening of the elevator shaft; through the omnidirectional laying of the outer horizontal protective component 31, the middle horizontal protective component 32, and the inner horizontal protective component 33 within the horizontal opening of the elevator shaft in both lateral and longitudinal directions, the safety protection of the horizontal opening of the elevator shaft is achieved; the protection of the horizontal and vertical openings of the elevator shaft is independent of each other, which can improve the overall safety of elevator shaft construction, while also reducing construction difficulty and workload. This invention can ensure safety during elevator shaft construction and cleaning efficiency after construction; every step is crucial, ensuring the safety protection of the elevator shaft and the safety of construction personnel.
