[0024] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0025] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0026] See Figures 1-6 As shown, the elevator shaft construction platform provided in this application includes a frame 10 and a cantilever mechanism 20.

[0027] The frame 10 is placed on a predetermined floor 100 in the elevator shaft, which is the floor where the masonry work will be carried out. The inner bottom surface of the frame 10 is a working surface 11, which is used to support personnel and / or materials. Construction personnel and construction materials can be supported on the working surface 11 so that construction personnel can carry out masonry work on the walls of the predetermined floor of the elevator shaft.

[0028] The cantilever mechanism 20 is connected to the top of the frame 10. The cantilever mechanism 20 is used to erect the frame 10 on the top of the preset floor 100 of the elevator shaft, wherein the top of the preset floor 100 of the elevator shaft is the bottom of the upper floor.

[0029] In this embodiment, the frame 10 is positioned on the preset floor 100 of the elevator shaft by means of a cantilever mechanism 20 erected on top of the preset floor 100. The inner bottom surface of the frame 10, which serves as the working surface 11, can support construction personnel and materials, facilitating masonry work on the preset floor. Compared to the method of erecting a steel pipe operating platform on each preset floor in related technologies, this significantly improves construction efficiency and safety. Furthermore, the frame 10 has a gap between itself and the side wall of the elevator shaft, eliminating the risk of wall instability. The elevator shaft construction platform provided in this embodiment is detachable and reusable, facilitating reuse and reducing reuse costs.

[0030] In some embodiments, when it is necessary to move this elevator shaft construction platform to another preset floor 100, it can be raised and lowered using a lifting device. See also Figure 1 As shown, the elevator shaft construction platform provided in this application also includes a lifting device 30. The lifting device 30 is installed on the top floor 101 of the elevator shaft. The frame 10 is provided with a lifting device 12. The lifting device 30 is connected to the lifting device 12. The lifting device 30 is used to lift the frame 10 to the corresponding building floor, which is a different preset floor 100, so as to carry out masonry work on the inner wall of the elevator shaft of the preset floor 100.

[0031] The lifting device 20 can be an electric hoist, capable of bearing a lifting weight of 3t to support the weight of this construction platform.

[0032] To improve the stability of frame 10 when it is lifted, see Figure 1 As shown, the elevator shaft construction platform provided in this embodiment also includes a safety rope 40. One end of the safety rope 40 is connected to the frame 10. The safety rope 40 is used to keep the frame 10 stable when the lifting device 30 lifts the frame 10, and can prevent the frame 10 from swaying in the radial direction of the elevator shaft.

[0033] See Figure 1 and Figure 2 As shown, the working surface 11 of the frame 10 is also connected to the walkway 13. The walkway 13 is rotatably connected to the working surface 11 so that after the walkway 13 is rotatably unfolded, it can be erected on the preset floor 100 of the elevator shaft, which facilitates the entry of construction personnel into the interior of the frame 10 and improves safety.

[0034] In some embodiments, the frame 10 is also provided with an opening (not shown in the figure) facing a preset floor 100 of the elevator shaft, and the walkway 13 is installed in a flipped manner on the side where the opening is provided, so that after the walkway 13 is erected to the preset floor 100, construction workers can enter the interior of the frame 10 through the opening via the walkway 13.

[0035] See Figures 1-4 As shown, the frame 10 also includes an intermediate layer 14 located between the top and bottom of the frame 10. This intermediate layer 14 allows construction workers to enter and perform masonry work on the upper part of the elevator shaft inner wall corresponding to the preset floor 100. The intermediate layer 14 divides the interior of the frame 10 into an upper working layer and a lower working layer, allowing construction workers to perform corresponding construction work on both layers to masonry the entire inner wall of the elevator shaft corresponding to the preset floor 100. The aforementioned opening is located on the side of the lower working layer facing the preset floor 100 of the elevator shaft, facilitating access for construction workers.

[0036] To protect construction workers, the frame 10 also includes an upper fence 15 and a lower fence 16. The upper fence 15 is installed around the upper working layer, and the lower fence 16 is installed around the lower fence, which can prevent objects or people from falling from height and improve safety.

[0037] To facilitate access for construction workers to the upper working level, a ladder 17 is provided on the lower working level, and an entrance / exit (not shown in the figure) is provided on the middle level 14. The ladder 17 connects the lower working level with the entrance / exit, and construction workers can enter and exit the upper working level through the entrance / exit via the ladder.

[0038] See Figure 2 , Figures 4-6 As shown, the support mechanism 20 includes two sets of support components 21, which are respectively arranged on opposite sides of the top of the frame 10 and are detachably connected to the top of the frame 10.

[0039] Specifically, the cantilever component 21 is connected to the top of the frame 10 in a cantilevered and detachable manner. After it forms a cantilever relative to the frame 10, it can be erected on the top of the preset floor 100 to support the frame 10.

[0040] In this embodiment, the cantilever assembly 21 includes at least two cantilever plugs 211. At least two socket holes are provided on opposite sides of the top of the frame 10. The at least two cantilever plugs 211 are telescopically connected to the at least two socket holes respectively, and can be erected on the top of the preset floor 100 of the elevator shaft after the cantilever plugs 211 extend to the outside of the socket holes.

[0041] It should be noted that the top of the frame 10 can be made of square steel, and the two ends of the inner cavity of the square steel can be formed into two socket holes. The socket 211 can be made with a radial dimension smaller than the inner diameter of the square steel forming the top of the frame 10, so that it can be connected to the inner cavity of the square steel by plugging in, which is convenient for assembly.

[0042] In summary, the suspended elevator shaft construction platform provided in this application positions the frame at a predetermined floor by using a cantilever mechanism erected on top of the floor. The inner bottom surface of the frame, serving as the working surface, can support construction personnel and materials, facilitating masonry work on the predetermined floor. Compared to related technologies that use steel pipe platforms erected on each predetermined floor, this significantly improves construction efficiency and safety. Furthermore, the gap between the frame and the side walls of the elevator shaft eliminates the risk of wall instability. The elevator shaft construction platform provided in this embodiment is disassembled and reusable, facilitating secondary use and reducing reuse costs.

[0043] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
