DETAILED DESCRIPTION
[0020] The present application will be described in detail below with reference to the embodiments, but the present application is not limited to these embodiments.
[0021] An elevator shaft operation platform, characterized in that, comprising:
[0022] A concrete placing machine climbing frame 2 located in the elevator shaft 1, the concrete placing machine climbing frame 2 is supported on the poured concrete 3;
[0023] A guard platform 4 installed on the side of the concrete placing machine climbing frame 2 and located on the poured concrete 3, the guard platform 4 comprises a telescopic support and a movable flap 5 hinged to the telescopic support, the movable flap 5 overlaps the floor of the poured concrete 3, the telescopic support comprises a plurality of transverse telescopic rods and a plurality of longitudinal telescopic rods, the transverse telescopic rods and the longitudinal telescopic rods are arranged in the center of the cross shape to form a channel space, the channel space is used to pass through the concrete placing machine climbing frame 2, and the transverse telescopic rods and the longitudinal telescopic rods are welded with the standard section of the concrete placing machine climbing frame 2.
[0024] Specifically, the concrete placing boom's climbing frame is located within the elevator shaft, directly supported on the poured concrete, providing a stable foundation for the entire operating platform. The climbing frame's design allows for gradual ascent as the concrete pouring height increases, ensuring the continuity of the construction process. A protective platform is installed around the perimeter of the concrete placing boom's climbing frame, forming a surrounding protective space to ensure the safety of construction personnel. The protective platform consists of telescopic supports and movable flaps, offering high flexibility and adaptability. The telescopic supports include several transverse and longitudinal telescopic bars arranged in a grid pattern, forming a robust frame. The design of the transverse and longitudinal telescopic bars allows for adjustment according to the actual dimensions of the elevator shaft, ensuring the platform's stability and adaptability. A passageway is formed at the center of the telescopic supports for the concrete placing boom's climbing frame to pass through, ensuring smooth operation of the construction equipment. The movable flaps are hinged to the telescopic supports, allowing for flexible rotation and flipping to adapt to different construction environments and needs. The movable flaps overlap the poured concrete floor slab, further enhancing the platform's stability and safety. The horizontal and vertical telescopic rods are welded together with the standard sections of the concrete placing boom climbing frame to form an integral structure, which enhances the strength and stability of the platform.
[0025] It's worth noting that the protective platform's design provides construction workers with a safe and stable working environment, reducing the risks of working at heights. The flexibility of the movable flap and telescopic support allows the platform to adapt to different construction environments and needs, further improving construction safety. The telescopic support and movable flap design also allow the platform to adapt to elevator shafts of different sizes, reducing the need to replace the platform due to size incompatibility. The platform's adaptability is further reflected in its ability to gradually rise as the construction height increases, ensuring the continuity of the construction process. The platform's stability and safety allow construction workers to focus more on the construction task, improving construction efficiency. The synchronous rise of the concrete placing boom's climbing frame and the platform reduces waiting time during construction, further improving efficiency. Simultaneously, the platform's reusability reduces long-term construction costs. The platform's flexibility and adaptability reduce the need to replace the platform due to size incompatibility, further reducing costs.
[0026] The horizontal telescopic rod / longitudinal telescopic rod includes a first connecting rod 6 and a second connecting rod 7. The first connecting rod 6 is sleeved inside the second connecting rod 7 to realize the extension and retraction of the second connecting rod 7 in the length direction of the first connecting rod 6. When the horizontal telescopic rod and the longitudinal telescopic rod are distributed in a grid pattern, the first connecting rods are connected to each other and welded to the standard section of the concrete placing boom climbing frame.
[0027] The first connecting rod 6 has an insertion channel 8 at one end near the second connecting rod 7. The second connecting rod 7 is nested in the insertion channel 8. The top of the second connecting rod 7 has a plurality of insertion slots 9 evenly distributed. The top of the first connecting rod 6 has a threaded through hole 10 communicating with the insertion channel 8. The threaded through hole 10 and the insertion slots 9 are adapted to each other, and a threaded rod 11 is inserted into the threaded through hole 10 and the insertion slots 9. A first limiting block 12 is provided on the side wall of the insertion channel 8 near the opening end. The first limiting block 12 is provided on the first connecting rod 6. The outer wall of the second connecting rod 7 is provided with a second limiting block 13 adapted to the first limiting block 12.
[0028] Specifically, both the lateral and longitudinal telescopic rods are composed of a first connecting rod and a second connecting rod. The first and second connecting rods are connected by a sleeve, allowing the second connecting rod to freely extend and retract along the length of the first connecting rod. One end of the first connecting rod has a insertion channel whose shape and size match the second connecting rod. The second connecting rod is completely nested within the insertion channel of the first connecting rod, forming a tight sleeve connection. To fix the telescopic rod at a specific length, several insertion slots are evenly distributed on the top of the second connecting rod. The top of the first connecting rod has a threaded through hole communicating with the insertion channel; the shape and size of this threaded through hole match the insertion slots. When the second connecting rod extends or retracts to the desired position, the threaded rod passes through the threaded through hole and inserts into the corresponding insertion slot, thus fixing the telescopic rod. To prevent the second connecting rod from excessively sliding or falling out within the insertion channel, a first limiting block is provided on the side wall of the insertion channel near the opening. A second limiting block, adapted to the first limiting block, is provided on the outer wall of the second connecting rod. When the second connecting rod extends to its limit position, the first and second limiting blocks will come into contact with each other and prevent it from moving further, thus ensuring the stability and safety of the telescopic rod.
[0029] The overall height of the telescopic rod can be flexibly adjusted by changing the extension length of the second connecting rod within the first connecting rod to accommodate elevator shafts of different sizes. The sleeve and threaded fixing method ensures a stable connection during extension and retraction, preventing loosening or detachment. The extension and fixing operations are relatively simple, requiring only the rotation of the threaded rod for both fixing and releasing, improving construction efficiency. The limit block design ensures the safety and stability of the telescopic rod during extension and retraction, preventing accidents caused by over-extension.
[0030] The second connecting rod 7 is connected to the movable flap 5 by a combined hinge;
[0031] The combined hinge includes a hinge fixing cylinder 14 and a hinge rotating shaft 15. The hinge rotating shaft 15 is welded to the end of the second connecting rod 7, and the hinge fixing cylinder 14 is welded to the movable flap 5. The hinge fixing cylinder 14 is mounted on the hinge rotating shaft 15 to achieve a rotatable connection.
[0032] Specifically, the modular hinge consists of two parts: a hinge fixing cylinder and a hinge rotation shaft. The hinge rotation shaft is welded to the end of the second connecting rod to form a single integral structure. The hinge fixing cylinder is also welded to the movable flap, forming a single integral structure as well. The hinge fixing cylinder is designed as a hollow cylindrical structure, with its inner diameter matching the outer diameter of the hinge rotation shaft. When the hinge fixing cylinder is placed on the hinge rotation shaft, a tight rotational connection is formed between the two. This rotational connection allows the movable flap to rotate and flip within a certain range relative to the second connecting rod, thus adapting to different construction environments and requirements.
[0033] It is worth noting that the rotational connection between the hinge fixing cylinder and the hinge rotation axis offers high flexibility and stability. This allows the movable flap to easily open and close while maintaining structural stability. The hinge rotation axis is typically made of wear-resistant and corrosion-resistant materials to ensure long-term reliability and durability. Through the combined hinge connection, the movable flap can rotate and flip flexibly to adapt to different construction environments and needs. This flexibility enhances the platform's adaptability and practicality, making operations more convenient for workers. The tight rotational connection between the hinge fixing cylinder and the hinge rotation axis ensures structural stability. Even when working at heights or under heavy loads, the movable flap remains stable and is less prone to swaying or falling off. The combined hinge design makes installation and maintenance relatively simple and convenient. The welded connections between the various hinge components reduce the risk of loosening and falling off, while also facilitating later maintenance and replacement.
[0034] In order to match the size of different shafts, the movable flaps can also be replaced accordingly.
[0035] An extension plate 16 is provided on one side of the movable flap 5, and the extension plate 16 is rotatably connected to the movable flap 5.
[0036] The extension plate 16 on each of the movable flaps 5 is located on the same side of the corresponding movable flap 5.
[0037] Specifically, an extension plate is a plate-like structure attached to one side of the movable flap to expand its area or provide additional support. The extension plate is connected to the movable flap via a swivel connection, allowing the extension plate to rotate relative to the movable flap within a certain range. This swivel connection is typically achieved through hinges, latches, or other similar connectors. In this design, the extension plate is connected to one side of the movable flap via a set of hinges or latches, enabling the extension plate to rotate about a central axis. This connection method allows the extension plate to be extended or retracted as needed to adapt to different construction environments and requirements.
[0038] The extension plates on each movable flap are positioned on the same side of the corresponding flap, which helps maintain the balance and stability of the entire platform. When all the extension plates are deployed simultaneously, they form a continuous support surface, providing construction workers with a more spacious and safer working space.
[0039] It is worth noting that the extension plate also overlaps the already poured concrete.
[0040] The protective platform 4 is also fixed with a galvanized steel wire layer 17.
[0041] Specifically, the galvanized steel wire layer is woven from galvanized steel wire, possessing good strength and corrosion resistance. The galvanizing treatment enhances the wire's rust resistance and extends its service life. The galvanized steel wire layer is securely fixed to the surface of the protective platform, forming a continuous mesh structure. Fixing is achieved through welding, bolting, or other reliable methods to ensure the wire layer does not detach or shift. The primary function of the galvanized steel wire layer is to provide additional safety protection. It prevents workers or tools from accidentally falling from the platform, increasing safety during construction. Simultaneously, the wire layer also possesses a certain load-bearing capacity, capable of withstanding a certain degree of impact and load.

Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any changes or modifications made by those skilled in the art without departing from the scope of the technical solution of this application using the disclosed technical content are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
