It is only for the convenience of describing the present invention rather than requiring the present invention to be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be directly connected or indirectly connected through an intermediate component. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0028] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0029] As Figures 1 to 4 shown, an elevator shaft protection construction platform includes a support 1, a foot 2 fixed on one side of the lower part of the support 1, and a protective platform 3 fixed on the top of the support 1. At least three spaced-apart columns 4 are vertically fixed on the protective platform 3. The columns 4 extend beyond the lower surface of the protective platform 3. A longitudinal pipe 5 and a transverse pipe 6 are connected to the columns 4 through fasteners 8. The longitudinal pipe 5 and the transverse pipe 6 are parallel to the protective platform 3 and perpendicular to each other. One end of the longitudinal pipe 5 and the transverse pipe 6 can extend out of the protective platform 3. When there are three columns 4, they are arranged in an equilateral triangle. However, considering the convenience of subsequent scaffolding construction, preferably, as Figures 1 to 4 shown, there are four columns 4 and they are arranged in a rectangle. The extending ends of the longitudinal pipe 5 and the transverse pipe 6 are preferably perpendicular to the side line of the current protective platform.

[0030] Further, as Figures 1 to 4As shown, a longitudinal tube 5 is connected to at least two columns 4 by fasteners 8, and a transverse tube 6 is connected to at least two columns 4 by fasteners 8 to ensure a firm connection and ensure that no slippage occurs when the ends of the longitudinal tube 5 and the transverse tube 6 are against the elevator shaft wall; the columns 4, the longitudinal tube 5 and the transverse tube 6 are all made of scaffolding steel pipes, and the three have the same diameter. This material is very common on construction sites, and the fasteners 8 are scaffolding fasteners 8, U-shaped clips, etc.

[0031] Further, such as Figures 1 to 4 As shown, the elevator shaft protection construction platform includes at least two longitudinal pipes 5 and two transverse pipes 6, and the two longitudinal pipes 5 and the transverse pipes 6 are roughly evenly distributed on the side of the protection platform 3; in one embodiment, the transverse pipes 6 are arranged in the left-right direction, and the longitudinal pipes 5 are arranged in the front-back direction, and the side of the transverse pipe 6 away from the support leg 2 is extended out of the protection platform 3, that is, the transverse pipe 6 is extended toward Figure 1 When in use, the length of the horizontal pipe 6 is adjusted according to the size of the elevator shaft to match it, so that when the elevator shaft protection construction platform is against the wall through the left end of the horizontal pipe 6, the protection platform 3 is in a state as horizontal as possible; the longitudinal pipe 5 can be extended from the front or rear side of the protection platform 3; scaffolding boards, formwork and other plates can also be covered on the exposed longitudinal pipes 5 and horizontal pipes 6 to prevent people or objects from falling from the gap between the protection platform 3 and the elevator shaft.

[0032] Further, such as Figure 1 , Figure 3 , Figure 4 As shown, a top sheet 7 is fixed to one end of the longitudinal tube 5 and the transverse tube 6, and the size of the top sheet 7 is larger than the diameter of the longitudinal tube 5 and the transverse tube 6 to increase the contact area with the elevator shaft wall.

[0033] like Figure 2 As shown, the protection platform 3 includes a platform frame 11 and a platform plate fixed on the top surface of the platform frame 11. The platform frame 11 includes a rectangular outer frame and a grid-shaped inner frame fixed inside the outer frame. The fixed position of the column 4 is close to the intersection of the grid-shaped inner frame. When the column 4 only extends downward beyond the protection platform 3, a cylindrical mounting seat can be fixed on the upper end of the column 4, and then the cylindrical mounting seat can be welded or bolted to the protection platform 3. The upper end of the column 4 can also be directly welded to the platform plate and the platform frame 11 of the protection platform 3. Figure 1 , Figure 4 As shown, the column 4 may also extend beyond the upper surface of the protective platform 3; in this case, it is preferred to make holes on the platform plate at intervals from the platform frame 11, and then pass the column 4 through the platform plate, and then weld the column 4 to the platform plate and the platform frame 11 or fix them by means of U-shaped clips or the like.

[0034] Further, such as Figure 2As shown in the figure, an installation piece 10 is fixed at the position where the platform frame 11 is connected to the support 1. The installation piece 10 is fixed at the junction of the grid-shaped inner frame and the outer frame, and installation holes are provided on the installation piece 10. A lower installation piece and lower installation holes corresponding to the installation piece 10 are provided at the top of the support 1, and then the support 1 and the platform frame 11 are connected and fixed by bolts and nuts.

[0035] Furthermore, a lifting ring 9 for hoisting is provided on the upper surface of the protection platform 3.

[0036] Furthermore, as Figure 4 shown in the figure, the elevator shaft protection construction platform further includes a scaffolding built by using columns 4. The columns 4 are used as vertical supports, and the scaffold pipes are connected by fasteners as horizontal connections and diagonal connections, and an upper platform 12 is provided on the scaffold pipes of the upper horizontal connection. Since the height of the protection platform may be lower than the elevator shaft wellhead, a scaffolding and an upper platform 12 are built on the protection platform as a protection against falling from a height.

[0037] The utility model can be self-processed on the basis of commercially available elevator shaft protection construction platforms of the same type. By adjusting the extended lengths of the longitudinal pipes 5 and the transverse pipes 6, it can be adapted to elevator shafts of different sizes, and has good practicability.

[0038] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model are within the scope of protection of the pending claims of the utility model.
