A type of positioning high-altitude work safety railing Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically to a positioning type high-altitude operation guardrail. Background Technology

[0002] There are many existing technologies for safety railings for high-altitude operations, such as:

[0003] Chinese Patent (Application No.: CN202320722266.1) discloses a safety railing for high-altitude operations, including a base plate, a first protective plate fixedly connected to the top of the base plate, a slider slidably connected to the inner wall of the first protective plate, a second protective plate fixedly connected to one end of the slider, and a handle fixedly connected to the outer wall of the second protective plate. This invention, through the provision of a first protective plate, a first sliding groove, a second protective plate, bolts, sliders, a handle, and a toolbox, facilitates workers in placing tools inside the toolbox, reducing the labor intensity of workers. By pushing the second protective plate to move inside the first protective plate, the height of the second protective plate can be adjusted to accommodate workers of different heights. Then, rotating the bolt on the first protective plate and moving it into the second protective plate secures the second protective plate, thereby improving the safety of the device and reducing the dangers of high-altitude operations.

[0004] Traditional guardrails with relatively fragmented protective structures require drilling on-site and then fixing multiple uprights and crossbars with bolts during installation. This is cumbersome and inefficient. Furthermore, it is inconvenient to quickly and repeatedly disassemble and reinstall the guardrail in different locations for different high-altitude working environments, reducing its reusability. Guardrails with more fixed protective structures occupy a large amount of space, making subsequent transportation and storage inconvenient and reducing their practicality. Summary of the Invention

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please refer to Figures 1-5. This embodiment provides a positioning-type high-altitude work safety railing, including a positioning frame 1. Considering that the installation of safety railings in traditional technology is cumbersome, has low installation accuracy, is not convenient for quick installation and disassembly, and occupies a large space, reducing the reusability and practicality of the safety railing, a protective component 2 is provided on the top of the positioning frame 1. The protective component 2 includes a first side plate 21 and a second side plate 22. The first side plate 21 and the second side plate 22 are rotatably connected to the four corners inside the positioning frame 1 by rotating rods 23 fixedly connected at both ends below, so that the first side plate 21 and the second side plate 22 can rotate above the positioning frame 1 to open or fold the safety railing. Sliding plates 27 are slidably connected inside the first side plate 21 and the second side plate 22, and the protection height can be adjusted by sliding the sliding plates 27 up and down.

[0033] In summary, the improvement of this embodiment lies in:

[0034] On the one hand, the protective component 2 is flexibly installed on the top of the positioning frame 1. In the actual installation process, it is only necessary to fix the installation position of the positioning frame 1. After the protective component 2 is unfolded, a complete protective fence can be quickly formed to cover the edge of the high-altitude platform. Compared with the traditional protective fence, it is simpler and faster to install.

[0035] On the other hand, when the guardrail needs to be disassembled and moved to other locations for protective work, the protective component 2 can be folded on top of the positioning frame 1 to reduce the space occupied by the guardrail. Compared with the traditional unfolding guardrail, it is more convenient to transport and store, and reduces transportation costs.

[0036] Based on the above, other structures also need to be disclosed in detail, such as:

[0037] Positioning feet 11 are fixedly connected to the four corners of the bottom of the positioning frame 1, and fixing plates 12 are fixedly connected to the four corners of the inner side of the positioning frame 1. Expansion bolts 13 are installed inside the fixing plates 12. A working platform 3 is installed at the bottom of the positioning frame 1, and the positioning feet 11 are engaged with the internal interface of the working platform 3. During installation, the positioning frame 1 is first initially positioned by engaging with the internal interface of the working platform 3 through the positioning feet 11 at the bottom. Then, expansion bolts 13 are added inside the fixing plates 12, and the installation position of the positioning frame 1 is fixed by threaded connection between the expansion bolts 13 and the working platform 3. This eliminates the need for repeated measurement and adjustment, shortening the installation time.

[0038] One end of the rotating rod 23 is fixedly connected to a limiting plate 24, which is locked by external bolts. After the position of the positioning frame 1 is determined, the protective component 2 is quickly unfolded to form a complete protective fence by rotating the first side plate 21 and the second side plate 22, so that the first side plate 21 and the second side plate 22 are perpendicular to the positioning frame 1. Then, the ends of the first side plate 21 and the second side plate 22 are initially locked by the external locking limiting plate 24, which can prevent the first side plate 21 and the second side plate 22 from continuing to rotate and initially fix the position of the first side plate 21 and the second side plate 22. The left and right ends of the first side plate 21 are symmetrically fixedly connected to the snap-fit ​​frame 25, and the front and rear ends of the second side plate 22 are symmetrically fixedly connected to the snap-fit ​​block 26. When the first side plate 21 and the second side plate 22 are rotated to determine the installation position, the snap-fit ​​block 26 is snapped into the snap-fit ​​frame 25 to ensure the accuracy of the relative position between the first side plate 21 and the second side plate 22, and at the same time, they restrain each other and improve the stability of the first side plate 21 and the second side plate 22.

[0039] Each of the first side plate 21, the second side plate 22, and the sliding plate 27 has through holes 28 at both ends, with U-shaped pins 29 installed inside the through holes 28. Different high-altitude work environments may require different protective heights. Therefore, by installing sliding plates 27 inside both the first and second side plates 21 and 22, the sliding plates 27 slide up and down within these plates, allowing the first and second side plates 21 and 22 to engage with each other, thus increasing the protective height of the guardrail in multiple ways. Multiple through holes 28 are located at different heights inside the first and second side plates 21 and 22. By aligning the through holes 28 at the bottom of the sliding plate 27 with the through holes 28 in the first and second side plates 21 and 22, and then inserting the U-shaped pins 29 into the through holes 28, the height position of the sliding plate 27 is locked, improving the convenience of manual adjustment and enabling flexible adjustment of the guardrail to meet different height protection requirements, thereby expanding the applicability of the guardrail.

[0040] Both the first side plate 21 and the second side plate 22 are slidably connected to a connecting plate 210. Several fixing rods 211 are fixedly connected to the bottom of the connecting plate 210. The rods 211 pass through the first side plate 21 and the second side plate 22 and engage with the inside of the positioning frame 1, thus fixing the vertical position of the first side plate 21 and the second side plate 22. The fixing rods 211 are also engaged with the inside of the working platform 3. After the positions of the first side plate 21 and the second side plate 22 are determined, pressing down on the connecting plate 210 connected to the first side plate 21 and the second side plate 22 simultaneously engages the multiple fixing rods 211 at the bottom of the connecting plate 210 into the positioning frame 1 and the working platform 3, increasing the stability of the bottom connection of the guardrail. This method is simple and convenient, effectively reducing the number of bolts used, ensuring the stability of the guardrail while improving installation efficiency, facilitating repeated disassembly and reuse of the guardrail, and enhancing its reusability.

[0041] In summary, the working principle of this solution is as follows:

[0042] When moving the guardrail, the protective component 2 folds and retracts to the top of the positioning frame 1, reducing the space occupied by the guardrail and facilitating its transportation and storage. When installation is required, the guardrail is moved to the top of the work platform 3. The positioning frame 1 first engages with the internal interface of the work platform 3 via the positioning feet 11 at the bottom to initially position the positioning frame 1. Then, expansion bolts 13 are added inside the fixing plate 12, and the installation position of the positioning frame 1 is fixed by threaded connection between the expansion bolts 13 and the work platform 3, eliminating the need for repeated measurements. After adjusting and shortening the installation time, once the position of the positioning frame 1 is determined, the protective component 2 is quickly unfolded to form a complete protective fence by rotating the first side plate 21 and the second side plate 22, making the first side plate 21 and the second side plate 22 perpendicular to the positioning frame 1. Then, the ends of the first side plate 21 and the second side plate 22 are initially locked by the external locking limit plate 24, which can prevent the first side plate 21 and the second side plate 22 from continuing to rotate, and the position of the first side plate 21 and the second side plate 22 is initially positioned and fixed. At the same time, the snap-fit ​​block 26 is engaged and connected. Inside the snap-fit ​​frame 25, the relative positions of the first side plate 21 and the second side plate 22 are ensured to be accurate, while also mutually constraining each other to improve the stability of the first side plate 21 and the second side plate 22. Different high-altitude working environments may require different protective heights. According to the protective requirements, the sliding plate 27 is slid up and down inside the first side plate 21 and the second side plate 22 to adjust the height of the sliding plate 27. Then, the through hole 28 at the bottom of the sliding plate 27 is aligned with the through holes 28 in the first side plate 21 and the second side plate 22. Finally, the U-shaped pin 29 is inserted into the through hole 28. In step 8, the height position of the sliding plate 27 is locked to allow for flexible adjustment of the guardrail to meet different height protection requirements, thereby improving the applicability of the guardrail. Finally, by pressing down on the connecting plate 210 connected to the first side plate 21 and the second side plate 22 respectively, the multiple fixing rods 211 at the bottom of the connecting plate 210 are simultaneously engaged into the positioning frame 1 and the working platform 3, increasing the stability of the bottom connection of the guardrail. This effectively ensures the stability of the guardrail while improving the installation efficiency of the guardrail, facilitating repeated disassembly and reuse of the guardrail, and improving the reusability of the guardrail.
