The problem of edge safety protection of an elevator shaft is a non-negligible important point. High-rise buildings are typically provided with multiple elevator cars, and during construction of the building main structure, the elevator equipment is not installed, at which time the elevator locations of each floor leave a large opening (i.e., elevator hoistway). As the construction process advances, the floors become higher and the elevator shaft becomes deeper (which may be hundreds of meters deep). If constructors or heavy objects fall into the wellhead carelessly, the consequences cannot be assumed. Therefore, the elevator shaft mouth becomes a non-negligible risk factor in the construction process.
In general, in order to prevent personnel or objects from falling into an elevator shaft, a construction unit installs temporary balustrades around the elevator shaft. However, due to the complexity and unpredictability of the construction environment, it is still difficult to completely prevent personnel or objects from accidentally falling from the edge of the opening. Therefore, a temporary safety protection structure needs to be erected above the elevator shaft opening of each floor to prevent people or articles from carelessly falling into the opening.

Detailed Description
The technical scheme of the utility model is clearly and completely described below with reference to the accompanying drawings.
Example 1
Referring to fig. 1 to 4, an elevator shaft anti-falling protection structure comprises a floor slab 1, wherein an elevator shaft opening 2 is formed in the floor slab 1, and a wall body 3 is arranged on one side, located at the elevator shaft opening 2, of the floor slab 1.
The elevator shaft anti-falling protection device capable of shielding or opening the elevator shaft opening 2 is arranged on the floor slab 1, and the elevator shaft anti-falling protection device is provided with 2 groups of elevator shaft anti-falling protection components. The elevator shaft anti-falling protection assembly comprises a fixed seat 5, a connecting hinge 6 and a protection plate 8, wherein the fixed seat 5 is of a longitudinal strip-shaped structure, the fixed seat 5 is fixed on one side, close to an elevator shaft opening 2, of a floor slab 1, far away from a wall body 3, the protection plate 8 is of a rectangular net-shaped structure, one end of the protection plate 8 is rotatably connected with the fixed seat 5 through the connecting hinge 6, the protection plate 8 can rotate around the connecting hinge 6 to the other end of the protection plate 8 to be lapped on the wall body 3 above the elevator shaft opening 2, shielding of the elevator shaft opening 2 is achieved, the distance between one end, close to the wall body 3, of the protection plate 8 and the floor slab 1 is D, in the embodiment, the D is 10cm, and 2 groups of elevator shaft anti-falling protection assemblies are sequentially arranged along the longitudinal direction, and the upper part of the elevator shaft opening 2 is fully shielded through 2 protection plates 8 which are in close to alignment.
In the above structure, rotating the protection plate 8 leans the protection plate 8 against the wall body 3, and finally, 2 protection plates 8 are covered above the elevator shaft 2, and the protection plate 8 can effectively shield the elevator shaft 2. In this embodiment, the protection plate 8 with a rectangular mesh structure is specifically manufactured by welding 20×40 square tubes (in mm) in a crisscross manner, which can provide sufficient support for constructors and general weights, the manufacturing and installation processes are very simple, and steel plates (not shown in the figure) can be paved on the 20×40 square tubes in a crisscross manner by welding or other connection modes to strengthen the supporting capacity, and the fixing seat 5 is manufactured by adopting 60×60 square tubes (in mm) in a longitudinal arrangement manner, so that the end part of the protection plate 8 is firmly supported. The single protection plate 8 is relatively light in carrying due to the small width, and the protection plate 8 is flexibly folded or unfolded by being movably hinged by the connecting hinge 6, so that the protection plate 8 can be turned over to be lapped on the floor slab 1 when articles and the like need to be transported from the elevator shaft 2.
As shown in fig. 2, a buffer portion 19 is disposed on an end surface of the protection plate 8 near the wall 3, and the buffer portion 19 is made of an elastic wear-resistant material. In this embodiment, the buffer portion 19 specifically adopts a sheet or strip abrasion-resistant rubber, which fully covers an end surface of the protection board 8 near the wall body 3, and is used for buffering the impact force of the protection board 8 on the wall surface when the protection board 8 is covered, and avoiding noise or scratches while buffering and protecting the stress of the protection board 8.
The elevator shaft anti-falling protection assembly further comprises an auxiliary mechanism, the auxiliary mechanism comprises a fixed ring 10 and a pull rope 12, the fixed ring 10 is fixedly arranged on the protection plate 8 at one end close to the wall body 3, one end of the pull rope 12 is connected to the fixed ring 10, and the other end of the pull rope 12 can extend to one end, close to the connecting hinge 6, of the protection plate 8.
When the length of the protection board 8 is long and 3 or more protection boards 8 are distributed, the protection board 8 is difficult to turn over by applying force to the wall end of the protection board 8 by hand and the protection board 8 positioned inside is inconvenient to apply force, so that the technical problems are solved by the auxiliary mechanism in the structure, and the protection board 8 is turned over by pulling the pull rope 12 of the auxiliary mechanism, so that the convenience of turning over the protection board 8 is effectively improved.
Further, a connecting ring 13 is fixedly arranged at one end, close to the connecting hinge 6, of the protection plate 8, a hook 11 is connected to one end, close to the connecting hinge 6, of the pull rope 12, and the hook 11 can be hooked on the connecting ring 13.
