[0024] Reference Figure 1 , illustrates the overall structure of an elevator shaft operating platform in some embodiments. The elevator shaft operating platform comprises a support assembly 105 and a platform member 102. Support assembly 105 includes two support arms 101, which are rotatably connected. Both ends of support assembly 105 are connected to the wall of an elevator shaft 104, specifically, to the wall of a cast wall 103 within the elevator shaft. Platform member 102 is positioned above support assembly 105, which supports it. Support arms 101 can be made of steel pipes, and platform member 102 can be made of a flat plate, such as a wooden board or steel plate.

[0025] When installing the elevator shaft operating platform in the elevator shaft 104, the support assembly 105 can be folded to a certain extent (the two support arms 101 are rotatably connected, and folding means reducing the angle between the two support arms 101) so that the distance between the two ends of the support assembly 105 is less than the width of the elevator shaft, making it easier to move the entire support assembly 105 to a preset installation height in the elevator shaft 104. The support assembly 105 is then extended, and the two ends of the support assembly 105 are connected to the wall of the elevator shaft 104 to secure the support assembly 105 to the elevator shaft. After the support assembly 105 is secured, a platform is erected above the support assembly 105, and workers can then stand on the platform member 102 to carry out construction.

[0026] By adjusting the angle between the two support arms 101, the distance between the two ends of the support assembly 105 can be adjusted, so that the support assembly 105 of the operating platform can be placed in elevator shafts 104 of different sizes. The elevator shaft operating platform provided by the embodiment of the present invention has good size adjustability and good applicability. During the construction process, there is no need to spend a lot of time to modify the existing platform or build a new platform, thereby improving construction efficiency.

[0027] It should also be noted that when the elevator shaft operating platform is transferred to a different elevator shaft 104, the size of the platform member 102 usually needs to be adjusted, but this adjustment only requires simple cutting of the panel, which takes very little time compared to modifying the structure of the entire platform or building a new platform.

[0028] Reference Figure 1 and Figure 3 In some embodiments, the elevator shaft operating platform further includes a leveling member 106, which is clamped between the support assembly 105 and the platform member 102. The leveling member 106 is used to ensure the flatness of the platform member 102 and can transfer the load on the platform member 102 to the support assembly 105. In some embodiments, there are multiple leveling members 106, and the multiple leveling members 106 are distributed along the length direction of the support arm 101 (i.e., the left / right direction in the figure). The height of the leveling member 106 gradually increases from the center of the support assembly 105 to the end of the support assembly 105, and the tops of the leveling members 106 are located at the same horizontal height. Figure 1 C-shaped steel can be used as the leveling member 106, with multiple C-shaped steel members having different sizes. In other embodiments, the leveling member 106 can also be configured as an object with a horizontal top surface and an inclined bottom surface. The gap between the platform member 102 and the support assembly 105 is typically irregular in shape. Providing multiple leveling members 106 eliminates the need for a single object with a unique shape, reducing the difficulty of constructing the entire operating platform.

[0029] Reference Figure 1In some embodiments, the elevator shaft operating platform further includes a scaffold 107, which is connected to the top of the platform member 102. The platform member 102 supports the scaffold 107, and workers can climb to different heights of the scaffold 107 to perform construction at different locations.

[0030] In some embodiments, after the support assembly 105 is installed, the horizontal height of the connection between the two support arms 101 will be greater than the horizontal height of the connection between the support assembly 105 and the wall of the elevator shaft 104. Figure 1 The support assembly 105 is in the shape of a human figure, with the middle part protruding upward. Figure 2 The weight of platform member 102 and the load on platform member 102 are transferred along support arm 101 to both ends of support assembly 105. Part of this downward load is converted into a horizontal load and transferred to the cast wall 103 of the elevator shaft. Therefore, with this arrangement of support assembly 105, the elevator shaft operating platform can bear a greater weight. In addition, with this arrangement, when installing support assembly 105, stability can be achieved by applying a downward load in the middle (such as pressing or lightly tapping). When removing, detachment can be achieved by lifting the middle position of support assembly 105 upward, making installation and removal very convenient.

[0031] The present invention also provides an elevator shaft structure, referring to Figure 1 and Figure 4 Support assembly 105 also includes a connector 108, which is connected to the end of support arm 101. Connector 108 is provided with a first connecting tooth 401, and the wall of the elevator shaft is provided with a second connecting tooth 402. First connecting tooth 401 and second connecting tooth 402 engage with each other. The friction between second connecting tooth 402 and first connecting tooth 401 can offset a portion of the horizontal and vertical loads transmitted along support arm 101, thereby balancing the forces on support assembly 105 and securing support assembly 105 to the elevator shaft. This eliminates the need for openings in the wall of elevator shaft 104, reduces damage to the wall, and improves the structural stability of elevator shaft 104.

[0032] In some embodiments, connector 108 is rotatably connected to the end of support arm 101. This arrangement allows for greater flexibility in the angle of connector 108, preventing it from getting caught on the walls of elevator shaft 104 during the vertical movement of support assembly 105. Specifically, a pin connection between connector 108 and support arm 101 facilitates quick assembly and disassembly of support arm 101 and connector 108. A pin connection can also be employed between two support arms 101 to facilitate quick assembly and disassembly of the support components.

[0033] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
