[0029] To facilitate understanding of the protective cage provided by the embodiments of the present application, first, the application scenario thereof is described. The protective cage provided by the embodiments of the present application is applied to the field of high-altitude operation, such as tower crane, wind power and the like, for equipment with a climbing ladder. When a worker uses the climbing ladder, there is a high risk of climbing due to the high equipment, so a protective cage is arranged on the climbing ladder to protect the worker through the protective cage. However, the current protective cage is of a fixed structure, and the whole occupies a large space, especially during transportation, a large transportation space is required. Therefore, the embodiments of the present application provide a protective cage to reduce the space occupied by the protective cage during transportation. The specific drawings and embodiments are combined below to describe it in detail.

[0030] Reference Figures 1-5 , wherein, Figures 1-3 The schematic views of the protective cage at different angles when unfolded are shown; Figure 4 and Figure 5The schematic views of the guard cage in different angles in the folded state are shown. Referring to Figure 1 and Figure 4 It can be seen that the guard cage provided by the embodiment of the present application has two different states. When the guard cage is unfolded, the guard cage can be fixed on the climbing ladder and provide protection. When the guard cage is folded, the guard cage occupies a smaller space. The specific structure of the guard cage will be described in detail below with reference to the drawings.

[0031] Continuing to refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 the front view of the guard cage when unfolded is shown, Figure 2 the side view of the guard cage when unfolded is shown, Figure 3 the top view of the guard cage when unfolded is shown. The guard cage provided by the embodiment of the present application mainly comprises a plurality of arc-shaped plates 10 arranged at intervals and a plurality of support plates 20 arranged at intervals. Among them, the plurality of arc-shaped plates 10 are arranged at intervals along the height, and the plurality of support plates 20 are arranged at intervals along the axial direction of the arc-shaped plates 10. In the specific connection, the length direction of each support plate 20 is along the arrangement direction of the plurality of arc-shaped plates 10, and each support plate 20 is rotationally connected with each arc-shaped plate in the plurality of arc-shaped plates 10. That is, the plurality of arc-shaped plates 10 are connected through the plurality of support plates 20, and the plurality of arc-shaped plates 10 and the plurality of support plates 20 form a cage-shaped space after being connected, which is used as a space for the staff to climb.

[0032] In the specific arrangement, each arc-shaped plate 10 has an opening, and the openings of the plurality of arc-shaped plates 10 are arranged along the height direction. The opening is used to accommodate the climbing ladder. When the guard cage is connected with the climbing ladder, the end portions on both sides of the opening of the arc-shaped plate 10 are connection ends, which can be fixedly connected with the climbing ladder or the support member of the climbing ladder, so as to fix the guard cage and the climbing ladder. When the staff climbs the climbing ladder, the guard cage can provide stable protection. The support member of the climbing ladder mentioned above can be the equipment on which the climbing ladder is arranged or other components supporting the climbing ladder.

[0033] The guard cage provided by the embodiment of the present application has two different states. One is the unfolded state, as shown in Figure 1 , and the other is the folded state, as shown in Figure 5 . When the plurality of arc-shaped plates 10 are rotated to the first set position, the plurality of arc-shaped plates 10 are coaxially arranged, and the state is as shown in Figure 1 . In this state, the plurality of arc-shaped plates 10 are arranged at intervals along the vertical direction, and the plurality of arc-shaped plates 10 are parallel to each other, so that the guard cage forms a cage-shaped space. It can also be understood that in the state shown in Figure 1 , the arc-shaped plate 10 is perpendicular or approximately perpendicular to the support plate 20. When the plurality of arc-shaped plates 10 are rotated to the second set position, the plurality of arc-shaped plates 10 are stacked, and the state is as shown inFigure 5 In this state, the plurality of arc plates 10 are stacked together, and the arc plates 10 and the support plates 20 are stacked together, and the arc plates 10 and the support plates 20 are approximately parallel or form an acute angle.

[0034] As can be seen from the above description, the protective cage provided by the embodiments of the present application comprises a plurality of support plates 20 and a plurality of arc plates 10 to form a cylindrical structure to achieve the protection function. In addition, the support plates 20 and the arc plates 10 are rotatably connected, so that the protective cage can be folded, thereby facilitating the transportation of the protective cage. Therefore, the protective cage provided by the embodiments of the present application can provide reliable protection while being folded for transportation and storage, thereby occupying a small space.

[0035] In addition, when the support plates 20 and the arc plates 10 are rotatably connected, at least part of the support plates 20 and the arc plates 10 are rotatably connected and can be locked at least in the first set position. That is, when the protective cage is unfolded, the support plates 20 and the arc plates 10 can be locked to keep the protective cage in the unfolded state, so that the protective cage can provide stable protection function.

[0036] In a specific embodiment, when the support plates 20 and the arc plates 10 are rotatably connected, at least part of the support plates 20 and each arc plate 10 are rotatably connected through a rotating corner plate 40. When the rotating corner plate 40 is used to connect the support plates 20 and the arc plates 10, the rotating corner plate 40 can be rotated to adjust the difference in position change caused by the rotation of the support plates 20 and the arc plates 10, thereby improving the smoothness of the protective cage when unfolded and folded, and reducing the requirement for assembly accuracy. In a specific arrangement, one end of the rotating corner plate 40 is rotatably connected to the corresponding support plate 20, and the other end of the rotating corner plate 40 is rotatably connected to the corresponding arc plate 10. That is, the support plate 20, the rotating corner plate 40 and the arc plate 10 form a linkage assembly, thereby improving the flexibility of the part of the support plates 20 and the arc plates 10 when rotating. In an example, the rotating corner plate 40 can be a long strip plate, an L-shaped plate or other shaped plate, as long as it improves the flexibility of the connection between the support plates 20 and the arc plates 10.

[0037] As shown in FIGS. 1, 2 and 3, the protective cage provided by the embodiments of the present application comprises a plurality of arc plates 10 and a plurality of support plates 20. The plurality of arc plates 10 are arranged in a cylindrical shape, and the plurality of support plates 20 are arranged in a cylindrical shape and are arranged between the plurality of arc plates 10. The plurality of arc plates 10 and the plurality of support plates 20 are rotatably connected. Figure 1 As shown in FIGS. 1, 2 and 3, the protective cage provided by the embodiments of the present application comprises a plurality of arc plates 10 and a plurality of support plates 20. The plurality of arc plates 10 are arranged in a cylindrical shape, and the plurality of support plates 20 are arranged in a cylindrical shape and are arranged between the plurality of arc plates 10.

Figure 2 As shown in FIGS. 1, 2 and 3, the protective cage provided by the embodiments of the present application comprises a plurality of arc plates 10 and a plurality of support plates 20. The plurality of arc plates 10 are arranged in a cylindrical shape, and the plurality of support plates 20 are arranged in a cylindrical shape and are arranged between the plurality of arc plates 10. The plurality of arc plates 10 and the plurality of support plates 20 are rotatably connected.

[0038] When the support plate 20 is connected with the arc plate 10, the second support plate 22 and the third support plate 23 are respectively connected with the corresponding arc plate 10 through the rotating angle plate 40. The second support plate 22 and the third support plate 23 are connected with the arc plate 10 through the rotating angle plate 40, so that the smoothness of the protective cage when being unfolded and folded can be improved.

[0039] In addition, when the first support plate 21, the fourth support plate 24 and the fifth support plate 25 are connected with the arc plate 10, the first support plate 21, the fourth support plate 24 and the fifth support plate 25 are respectively connected with each arc plate 10 through the first bolt assembly 60 and can be locked. The position of the support plate 20 and the arc plate 10 can be locked through the locking of the first bolt assembly 60, so that the protective cage can be kept in an unfolded state, and of course, the protective cage can also be kept in a folded state.

[0040] In a specific arrangement, the fourth support plate 24 and the fifth support plate 25 are arranged at a distance from the opening of the arc plate 10. Since the two ends of the opening of the arc plate 10 are fixedly connected with the climbing ladder or the support of the climbing ladder during use, the fourth support plate 24 and the fifth support plate 25 are arranged at a distance from the opening of the arc plate 10, so that the part of the arc plate 10 suspended in the air can be better supported, and the support effect of the arc plate 10 can be improved.

[0041] With reference to Figure 2 and Figure 3 , the connecting end of the arc plate 10 provided by the embodiment of the present application is provided with a limiting support plate 50, and the limiting support plate 50 is a U-shaped plate. When the U-shaped plate is used as the connecting structure, the structural strength of the connecting end can be improved, so that stable support can be provided for the protective cage when the protective cage is connected with the climbing ladder or the support of the climbing ladder. In a specific implementable scheme, the limiting support plate 50 is an integral structure with the arc plate 10.

[0042] In an implementable scheme, the protective cage further comprises a second bolt assembly 30, and the second bolt assembly 30 is connected with the arc plate 10 in a one-to-one manner; each second bolt assembly 30 comprises a screw rod penetrating through two limiting support plates 50 opposite to each other, and two nuts threadedly connected with the screw rod; and the two nuts are located on the outer side of the two limiting support plates 50. When the above-mentioned second bolt assembly 30 is used, the two limiting support plates 50 can be locked on the climbing ladder through the second bolt assembly 30, so as to provide stable support for the protective cage.

[0043] The embodiment of the present application further provides a device, which comprises a device body and a climbing ladder fixed on the device body; further comprises the protective cage of any one of the above; wherein the climbing ladder is located in the protective cage; and the connecting end is fixedly connected with the climbing ladder or the device body.

[0044] In the technical scheme, the plurality of support plates 20 and the plurality of arc plates 10 are combined to form a cylindrical structure to achieve the protection function. In addition, the rotation connection between the support plate 20 and the arc plate 10 enables the protection cage to be foldable, thereby facilitating the transportation of the protection cage. Therefore, the protection cage provided by the embodiment of the present application takes into account the reliability and protection of the protection cage, and can be folded for transportation and storage, thereby occupying a small space.
