AI Technical Summary
During construction, the elevator wellhead lacks effective protective measures, which may cause construction personnel or heavy objects to fall into it, causing danger. The prior art uses guardrails and alarms to prevent falling parts, but the disassembly and assembly operations are complicated and inconvenient to use.
A modular maintenance-free elevator shaft protection mechanism is designed, including auxiliary frames and concrete covers. The auxiliary frame is installed in the elevator shaft entrance, and the concrete cover is mounted on the frame and is fixed by positioning columns and nuts to form a closed structure.
This design can effectively block the elevator shaft, prevent people or items from falling in, facilitate construction workers to walk, and quickly remove them when installing the elevator, simplifying the operation process.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of elevator shafts, and in particular relates to a modular maintenance-free elevator shaft protection mechanism. Background Art
[0002] Hospital buildings are generally equipped with multiple elevators. During the construction of the main structure of the building, the elevator equipment has not yet been installed. At this time, a huge hole (i.e., the elevator shaft) is left at the elevator position on each floor. As the construction process progresses, the floors are getting higher and higher, and the elevator shaft is getting deeper and deeper (up to hundreds of meters deep). If a construction worker or a heavy object accidentally falls into the shaft, the consequences will be disastrous. Therefore, the elevator shaft has become a dangerous factor that cannot be ignored during the construction process.
[0003] At present, in general, in order to prevent people or objects from falling into the elevator shaft, construction units will install temporary safety protection structures around the elevator shaft opening to prevent people or objects from accidentally falling into the hole. The previous construction method was to add various guardrails around the elevator shaft opening and set up various alarm and anti-fall components, which resulted in more disassembly and assembly procedures and was not convenient to use.
[0004] Therefore, based on the above problems, we designed a modular maintenance-free elevator shaft protection mechanism. Utility Model Content
[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a modular maintenance-free elevator shaft protection mechanism, which solves the technical problem that the existing elevator shaft construction protection is to add various guardrails around the elevator shaft opening and set various alarm and anti-fall components, resulting in more disassembly and assembly procedures and inconvenient use.
[0006] To achieve the above-mentioned object, according to an embodiment of the first aspect of the utility model, a modular maintenance-free elevator shaft protection mechanism is provided, comprising an elevator shaft, wherein a square opening is arranged in the elevator shaft;
[0007] Also includes:
[0008] An auxiliary frame is arranged in the square opening, and a trapezoidal installation notch is arranged on the auxiliary frame;
[0009] The concrete cover plate is arranged in the square opening, the bottom surface of the concrete cover plate protrudes downwards and is installed in cooperation with the trapezoidal installation notch.
[0010] A further improvement is that positioning columns are provided at the four corners of the surface of the auxiliary frame, the outer wall surface of the positioning columns is provided with threads, and nuts are threadedly connected to the positioning columns.
[0011] A further improvement is that through grooves for installing positioning columns are provided through the four corners of the concrete cover plate.
[0012] A further improvement is that the concrete cover plate is formed by pouring a steel cage and concrete, and is a prefabricated plate structure.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The utility model places the concrete cover plate on the auxiliary frame, so that the grooves at the four corners are placed on the positioning columns, the bottom surface of the concrete cover plate and the trapezoidal installation notch are installed in coordination, and then a nut is screwed on each positioning column to install the concrete cover plate in each square hole. The utility model can block the elevator shaft opening during construction through the above design, effectively preventing people or objects from accidentally falling into the hole, facilitating walking, and can be quickly removed when installing the elevator.

[0018] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] like Figure 1 As shown, a modular maintenance-free elevator shaft protection mechanism comprises an elevator shaft 1, in which a square hole 11 is arranged;
[0020] like Figure 1 As shown, the implementation also includes: an auxiliary frame 3, which is arranged in the square hole 11, and a trapezoidal installation notch 32 is arranged on the auxiliary frame 3;

It should also be noted that the actual size of each component in the application document is selected for installation before implementation according to the actual needs of the site. In addition, it should be noted that this application document is only for the existing elevator shaft construction protection, which is to add various guardrails around the elevator shaft opening, and to set various alarm and anti-fall components, resulting in more disassembly and assembly procedures and inconvenient use. Improvements are made, and other aspects are not involved; the working principle of this modular maintenance-free elevator shaft protection mechanism is introduced as follows:
