[0026] The present invention will be further described in detail below through specific embodiments:
[0027] In the embodiments of this utility model, such as Figures 1-3As shown, the protective structure includes: two cover plates 1; the two cover plates 1 are spliced together by detachable components 4 to form a protective body and can cover the pile hole; the cover plate 1 includes: an upper frame 101 and a lower frame 102, both of which are arc-shaped and connected by multiple supporting ribs 103; the upper frame 101 forms a protective area 105 and a hoisting area 106; the protective area 105 is provided with a first protective net; the hoisting area 106 is an open structure and is provided with a movable second protective net 2 to open or cover the hoisting area 106.
[0028] Specifically, in this embodiment of the invention, a 50cm high flange (i.e., a locking flange) is provided at the pile hole opening to prevent stones, mud, sand, tools, implements, short steel bars, and other objects on the ground from falling into the hole and injuring people. Of course, the work site must be cleaned up promptly, and excavated mud, sand, and stones must be removed immediately to ensure the area around the hole opening is clean, with no debris piled up within 3 meters of it. Furthermore, workers inside the pile hole must wear safety helmets before construction, and tools needed at the bottom of the hole must be delivered using lifting equipment; throwing tools into the pile hole is strictly prohibited.
[0029] In this embodiment of the invention, for pile holes under construction, workers need to enter the holes for construction. To facilitate worker access, two cover plates 1 are provided. The two cover plates 1 are detachably connected, so that when the two cover plates 1 form a protective body, they are used to cover the pile hole for protection; conversely, when the two cover plates 1 are separated, they are used to expose the pile hole for personnel access. Of course, to improve construction efficiency, when dismantling the cover plates 1, one cover plate 1 can be removed, leaving the other cover plate 1 at the pile hole for preparation for the next construction.
[0030] In this embodiment of the invention, during construction, it is necessary to hoist construction tools or materials such as mud and sand. To ensure the safety of workers inside the hole and improve hoisting efficiency, a protective area 105 and a hoisting area 106 are provided at each cover plate 1. The protective area 105 is equipped with a first protective net for protection. The hoisting area 106 is an open structure that allows for delivery by lifting equipment. During hoisting, personnel stand below the first protective net without removing the cover plate 1, and the pile hole is allowed to be partially opened, achieving partial opening and closing during hoisting operations to balance hoisting efficiency and safety. In addition, a movable second protective net 2 is provided in the hoisting area 106 to open or cover the hoisting area 106, achieving full coverage when not in operation to prevent falls from height. Meanwhile, in order to reduce the damage and interference of the hoisting area 106 to the structural strength of each cover plate 1, and to increase the hoisting area 106, each cover plate 1 has an opening in the hoisting area 106. The openings of the two hoisting areas 106 are arranged opposite to each other and can be spliced together to form a closed hoisting area.
[0031] Furthermore, the cover plate 1 includes an upper frame 101 and a lower frame 102, which are spaced apart in the vertical direction and connected by multiple support ribs 103. Thus, the cover plate 1 adopts a double-layer frame structure, which can further improve the structural strength of the cover plate 1 itself.
[0032] This embodiment uses a detachable connection between two cover plates 1 to facilitate quick opening or covering of the pile hole, thereby making it easier for workers to enter and exit the pile hole. Furthermore, each cover plate 1 is divided into two sections: a protection area 105 and a hoisting area 106. This ensures that the first protective net always covers the protection area 105, while the second protective net 2 is movably set in the hoisting area 106. During hoisting operations, the second protective net 2 can be used to open the hoisting area 106, achieving partial opening of the pile hole, thus balancing worker safety and hoisting efficiency. In non-operational states, the second protective net 2 can completely cover the hoisting area 106, effectively preventing falls from heights.
[0033] like Figure 2 As shown, in one embodiment, the cross-sectional area of the protective area 105 is larger than the cross-sectional area of the hoisting area 106. Specifically, to improve the protective safety of the protective area 105, this embodiment defines the cross-sectional area of the protective area 105 as larger than the cross-sectional area of the hoisting area 106, thereby achieving the purpose of partially opening the pile hole, increasing the protective area inside the hole, providing a larger standing area for workers, and balancing hoisting efficiency and worker safety. Preferably, the protective area 105 is arranged around the hoisting area 106. When workers are standing below the protective area 105, delivery is performed through the hoisting area 106 located in the middle, which improves the safety of workers inside the hole.
[0034] like Figures 1-3 As shown, in one embodiment, the upper frame 101 is provided with a plurality of protective ribs 104 spaced apart along a first direction and / or a second direction to form the protective area 105. Specifically, in order to further improve the structural strength of the cover plate 1, this embodiment provides a plurality of protective ribs 104 at the upper frame 101, with the protective ribs 104 spaced apart along the first and second directions, which can avoid stress concentration in the upper frame 101. Preferably, the first direction and the second direction are arranged at an angle. In this embodiment, the first direction and the second direction are perpendicular to each other, and the plurality of protective ribs 104 form a mesh structure, which can not only improve the structural strength of the cover plate 1, but also serve as a first protective net (the spacing between adjacent protective ribs 104 can be reasonably controlled).
[0035] like Figures 1-3As shown, in one embodiment, the second protective net 2 is rotatably connected to one of the two cover plates 1's protective areas 105 via a hinge 3, and can overlap to the other protective area 105. Specifically, to enable the protective area 105 to be opened or covered, this embodiment uses a hinge 3 to connect the protective area 105 and the second protective net 2. Simultaneously, to improve operational efficiency, a second protective net 2 can be provided for both protective areas 105; that is, a hinge 3 is provided at one protective area 105, and after connecting the second protective net 2 using the hinge 3, the second protective net 2 can open the protective area 105 or overlap to the other protective area 105 to cover both protective areas 105. Furthermore, to facilitate the manipulation of the second protective net 2, a traction rope (not shown) can be provided at the second protective net 2, extending to the upper frame 101, so that the second protective net 2 can be pulled to rotate accordingly. Alternatively, the traction rope can be replaced with a traction rod, increasing its rigidity and making it easier to manipulate.
[0036] like Figure 1 As shown, in one embodiment, the upper frame 101 and the lower frame 102 are arranged with the same center. Specifically, since the cross-section of the pile hole is circular, in order to adapt to it, both the upper frame 101 and the lower frame 102 in this embodiment are arc-shaped and arranged with the same center; the centers of the two can coincide with the center of the pile hole.
[0037] like Figure 2 , Figure 3 As shown, in one embodiment, the detachable component 4 includes: a plurality of first connecting ribs 401 and a plurality of second connecting ribs 402, wherein the plurality of first connecting ribs 401 are inserted one-to-one into the plurality of second connecting ribs 402. Specifically, in order to achieve a detachable connection between the two cover plates 1, this embodiment provides a plurality of first connecting ribs 401 and a plurality of second connecting ribs 402 on the opposite end faces of the two cover plates 1 respectively. The first connecting ribs 401 can be inserted into the second connecting ribs 402, and the two cover plates 1 are connected by a pull-out installation method. At the same time, in order to improve the protection and safety of the cover plates 1, their material is mostly heavy steel, so that the first connecting ribs 401 can be kept in the second connecting ribs 402 without much external force. Of course, the distance between the two cover plates 1 is determined by the length of the two connecting ribs, such as the exposed length of the first connecting ribs 401 and the installation length of the second connecting ribs 402.
[0038] Furthermore, such as Figures 2-4As shown, in one embodiment, the detachable component 4 further includes a cooperating pin 403 and a socket 404. The pin 403 is located in one of the protective areas 105 of the two cover plates 1, and the socket 404 is located in the other protective area 105. Specifically, in order to promptly determine the connection depth between the first connecting rib 401 and the second connecting rib 402, this embodiment provides a pin 403 at the protective rib 104 in one protective area 105 and a socket 404 at the protective rib 104 in the other protective area 105. Figure 4 As shown, the pin 403 in this embodiment is operated by a combination of rotation and pull-out.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
