Technical Field

[0001] This utility model relates to the field of PCCP pipe construction technology, and more specifically, to a PCCP construction operation platform with multi-stage telescopic extension. Background Technology

[0002] During PCCP pipe fitting construction operations, such as PCCP core repair work in the vertical storage area and PCCP steel fitting vertical welding assembly work, the construction work locations are not fixed and the working space is limited. The construction platform is time-consuming, labor-intensive and extremely inconvenient.

[0003] To address the issue of increased costs associated with temporary PCCP pipe fitting installation due to factors such as unfixed work locations and limited work space, this invention provides a multi-level telescopic PCCP installation platform.

[0004] This invention can save space, increase the mobility of construction operations, and enhance the safety of construction operations. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a construction operation platform for PCCP with multi-level telescopic extension.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a construction platform for PCCP with multi-stage telescopic extension, comprising: a telescopic frame and platform panels. The telescopic frame includes: a first telescopic frame, a second telescopic frame, a third telescopic frame, and a fourth telescopic frame. The telescopic frame is a 1 / 4 semi-circular arc frame. After four extensions and retractions, the telescopic frame forms a circumferential construction platform for the PCCP pipe fitting. The second telescopic frame extends from inside the first telescopic frame, and its outward extension simultaneously drives the laying of the first platform panel. The third telescopic frame extends from inside the second telescopic frame, and its outward extension simultaneously drives the laying of the second platform panel. The fourth telescopic frame extends from inside the third telescopic frame, and its outward extension simultaneously drives the laying of the third platform panel. The fourth telescopic frame itself carries the fourth platform panel for laying.

[0007] A further preferred embodiment: After the fourth telescopic frame extends outward, it forms a circumferential construction work platform with the first telescopic frame. The platforms are connected end to end, increasing the working surface of the platform and improving the safety of construction operations.

[0008] A further preferred embodiment: The first telescopic frame includes a second telescopic frame, a third telescopic frame, and a fourth telescopic frame, and the four are integrated into one unit. Each front-positioned frame of the telescopic frame is connected to the upper, middle, and lower three sets of platform panels of the rear-positioned frame.

[0009] A further preferred embodiment: The telescopic frame also includes casters, tracks, and platform panels. Casters are installed at the bottom of each telescopic frame, and tracks are installed inside each telescopic frame. Platform panels are movably laid on the tracks. During use, the telescopic frame is extended by moving the casters. When each front telescopic frame platform panel extends forward, it pulls the rear telescopic frame platform panel. The telescopic frame controls the amount of extension and retraction by connecting the length of the platform panels and realizes the laying of the rear telescopic frame platform panels. Thus, by completing four extensions and retractions, a circumferential construction operation platform is formed for the PCCP pipe fitting.

[0010] A further preferred embodiment: The telescopic frame is also equipped with a telescopic frame guardrail, and the workers will fasten their safety belts to the telescopic frame guardrail when working on the platform.

[0012] A further preferred embodiment: the track has several keels distributed at equal intervals, with an angle of 5° between two adjacent keels.

[0013] A further preferred embodiment: an upper steel plate and a lower steel plate are respectively installed at the top and bottom ends of the keel. Both the upper steel plate and the lower steel plate are 1.5mm thick steel plates. The keel, the upper steel plate and the lower steel plate form a longitudinal flexible platform frame.

[0014] Beneficial effects:

[0015] 1. During use, the telescopic frame is moved by the casters and extends and retracts four times to form a circumferential construction platform for the PCCP pipe fitting.

[0024] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0025] Please see Figure 1-5In this embodiment of the utility model, a construction platform for PCCP with multi-stage telescopic extension includes: a telescopic frame and a platform frame 11. The telescopic frame includes: a first telescopic frame 1, a second telescopic frame 2, a third telescopic frame 3, and a fourth telescopic frame 4. The telescopic frame is a four-stage nested 1 / 4 semi-circular arc frame. This unique shape design is to better adapt to the arc-shaped outer contour of the PCCP pipe fitting. After the telescopic frame extends in four stages, it fully covers the PCCP pipe fitting 16 to form a circumferential construction platform. The second telescopic frame 2 extends from inside the first telescopic frame 1, and the extension of the second telescopic frame 2 simultaneously drives the first platform frame 5 to be laid. The third telescopic frame 3 extends from inside the second telescopic frame 2, and the extension of the third telescopic frame 3 simultaneously drives the second platform frame 6 to be laid. The fourth telescopic frame 4 extends from inside the third telescopic frame 3, and the extension of the fourth telescopic frame 4... Simultaneously, the third platform frame 7 is laid, and the fourth telescopic frame 4, with its own fourth platform frame 8, is laid. The first frame section serves as the base to bear the overall load, while the last frame section, with its own fixed platform frame 11, completes the circumferential closure. Each extension triggers the corresponding platform frame 11 to automatically unfold via mechanical linkage. The four levels work together to form a continuous working surface. The key function is to realize the transformation of the platform from a retracted state to a full-circumferential working surface, reducing the construction time compared to traditional scaffolding. This design allows the platform frame 11 to be laid synchronously as the telescopic frame extends during the platform construction process, greatly improving construction efficiency and ensuring the continuity and stability of the platform construction. Each extension of the telescopic frame drives the corresponding platform frame 11 to be laid, gradually expanding the working platform area. This multi-level linkage design makes the entire platform construction process orderly and efficient, and can quickly form a complete circumferential working platform.

[0026] In this embodiment of the invention, the fourth telescopic frame 4 extends outward to form a circumferential construction platform with the first telescopic frame 1. The platforms are connected end to end, increasing the working surface and enhancing the safety of construction operations. This closed-loop platform structure significantly increases the working surface, providing workers with more space to perform their tasks, while also increasing safety. The closed-loop structure provides more stable support, reducing safety hazards such as edge falls.

[0027] In this embodiment of the utility model, the first telescopic frame 1 includes a second telescopic frame 2, a third telescopic frame 3, and a fourth telescopic frame 4, all of which are integrated into one unit. This compact integrated design saves storage space, and when not in use, each telescopic frame can be nested and stored. Each front-positioned frame of the telescopic frame is connected to the upper, middle, and lower three sets of platform panels 11 of the rear-positioned frame. Through this connection method, it can be ensured that during the telescopic process, each level of platform panel can stably follow the telescopic frame and complete the laying, ensuring the accuracy and stability of the platform construction.

[0028] In this embodiment of the utility model, the telescopic frame also includes casters 9, rails 10, and platform panels 11. Casters 9 are installed at the bottom of the telescopic frame. The function of the casters 9 is to enable the telescopic frame to move flexibly on the construction site and to easily adjust the position of the working platform to adapt to the construction needs of PCCP pipe fittings in different positions. Rails 10 are installed inside the telescopic frame. The rails 10 provide guidance for the laying and movement of the platform panels 11, ensuring that the platform panels move along a predetermined direction during the telescopic process. Platform panels 11 are movably laid on the rails 10. During use, the telescopic frame is extended by moving the casters 9. When each front telescopic frame platform panel 11 extends forward, it pulls the rear telescopic frame platform panel 11. The telescopic frame controls the amount of extension and retraction by connecting the length of the platform panels 11 and realizes the laying of the rear telescopic frame platform panels 11. Thus, by completing four extensions, a circumferential construction working platform is formed for the PCCP pipe fitting 16. After the construction work is completed, the telescopic frame can be moved and retracted by the casters, which greatly saves the space and increases the mobility of the construction work.

[0029] In this embodiment of the utility model, the telescopic frame is also equipped with a telescopic frame guardrail 15. When workers are working on the platform, they fasten their safety belts to the telescopic frame guardrail 15. The telescopic frame guardrail 15 plays a crucial protective role, preventing workers from accidentally falling off the platform and providing a reliable safety barrier for workers, thus ensuring the safety of construction workers' lives.

[0030] In this embodiment of the utility model, the platform frame 11 includes: a keel 12, an upper steel plate 13, and a lower steel plate 14. The platform frame 11 is a longitudinally flexible platform frame. The platform frame 11 is laid at the location where the track 10 of the telescopic platform frame 11 is laid. The keel 12 serves as the supporting structure of the platform frame 11 and can bear the weight of the workers and construction equipment, ensuring the load-bearing capacity of the platform. The upper steel plate 13 and the lower steel plate 14 are located at the top and bottom ends of the keel 12, respectively. They can not only enhance the overall strength of the platform frame 11, but also provide a relatively smooth working surface, which is convenient for workers to walk on and place construction tools.

[0031] In this embodiment of the utility model, a number of keels 12 are evenly distributed around the track 10, and the angle between two adjacent keels 12 is 5°. This evenly distributed design ensures the uniformity of the support of the platform frame 11 on the track 10, so that the platform is more evenly stressed when carrying heavy objects, and avoids the situation where the platform is damaged or deformed due to excessive local stress.

[0032] In this embodiment of the utility model, an upper steel plate 13 and a lower steel plate 14 are respectively installed at the top and bottom ends of the keel 12. Both the upper steel plate 13 and the lower steel plate 14 are 1.5mm thick steel plates. The thinner steel plate design reduces the overall weight of the platform frame 11 while ensuring a certain strength. The keel 12, the upper steel plate 13 and the lower steel plate 14 form a longitudinally flexible platform frame 11. The longitudinally flexible design allows the platform frame 11 to adapt to the curved surface of the PCCP pipe fitting to a certain extent, providing better fit and stability, and providing a good foundation for construction operations.

[0033] Working Principle: First, near the PCCP pipe fitting construction location, the construction platform, currently in its retracted state, is moved to a suitable position using the casters 9 mounted at the bottom of the telescopic frame. At this time, the second telescopic frame 2, the third telescopic frame 3, and the fourth telescopic frame 4 are housed inside the first telescopic frame 1, and all platform plates 11 are also retracted, resulting in a compact overall structure with minimal space occupation. Next, the telescopic frame begins to extend. The second telescopic frame 2 extends outward from inside the first telescopic frame 1, and simultaneously, a mechanical linkage triggers the automatic unfolding of the first platform plate 5, which is then laid on the corresponding track 10. Next, the third telescopic frame 3 extends outward from inside the second telescopic frame 2, simultaneously driving the second platform plate 6 to be laid. Then, the fourth telescopic frame 4 extends outward from inside the third telescopic frame 3, driving the third platform plate 7 to be laid, and the fourth platform plate 8 attached to the fourth telescopic frame 4 is also laid. With each stage of the telescopic frame extending, the platform plate 11 of the front telescopic frame pulls the platform plate 11 of the rear telescopic frame as it extends and retracts forward. The retractable platform frame 11 is used to control the extension and retraction of the platform frame 11 and to lay the platform frame 11 in a rear position. Finally, the fourth section of the retractable frame 4 extends outward and forms a circumferential construction platform with the first section of the retractable frame 1. The platforms are connected end to end to form a closed loop structure, which increases the working surface of the platform. Workers climb onto the built platform and fasten their safety belts to the retractable frame guardrail 15 to ensure their safety. Because the keel 12, upper steel plate 13 and lower steel plate 14 of the platform frame 11 form a longitudinally flexible platform frame, it can better adapt to the curved surface of the PCCP pipe fittings and provide a stable working foundation. Workers can place construction equipment and tools on the platform to carry out relevant construction work on the PCCP pipe fittings. During the construction process, if it is necessary to adjust the position of the working platform to adapt to the construction needs of PCCP pipe fittings in different positions, the retractable frame can be flexibly moved by the casters 9 to adjust the platform to a suitable position. After the construction work is completed, the retractable frame can be moved by the casters to retract the retractable frame. Each telescopic frame retracts sequentially into the previous telescopic frame, and at the same time, each platform shelf is also retracted, eventually returning to its initial storage state, greatly saving usable space.
