[0039] The following will describe the specific implementation manners of the present utility model in conjunction with the accompanying drawings.

[0040] As Figures 1 - 3 shown, an embodiment of the present application provides an aerial protection fence, which includes a first protection fence 1, a second protection fence 2, a third protection fence 3, and a fourth protection fence 4 placed on a reference plane.

[0041] The first protection fence 1, the second protection fence 2, the third protection fence 3, and the fourth protection fence 4 are detachably and fixedly connected in sequence to form a ring, and the protection surfaces of the first protection fence 1, the second protection fence 2, the third protection fence 3, and the fourth protection fence 4 enclose a protection structure around an operation platform 7 located above the reference plane.

[0042] Among them, the head end of the first protection fence 1 is connected to the protection surface of the fourth protection fence 4; the head end of the second protection fence 2 is connected to the protection surface of the first protection fence 1; the head end of the third protection fence 3 is connected to the protection surface of the second protection fence 2; the head end of the fourth protection fence 4 is connected to the protection surface of the third protection fence 3, as Figure 1 shown.

[0043] Specifically, the reference plane can be the ground around the lower part of the operation platform 7. When the operation platform 7 is the roof of a large vehicle, as Figure 1 shown, the first protection fence 1, the second protection fence 2, the third protection fence 3, and the fourth protection fence 4 are placed on the ground around the vehicle; the protection structure is as Figure 1 shown, and is a protection fence configuration around the roof; the placement trends of the first protection fence 1, the second protection fence 2, the third protection fence 3, and the fourth protection fence 4 are the same, and a part of the protection surface of each protection fence is located outside the protection structure. By adjusting the relative distances between the multiple protection fences, the size of each protection fence located outside the protection structure is changed, and then the size of the protection structure is changed to adapt to the size of the operation platform 7; the adjacent protection surfaces are perpendicular to each other.

[0044] By placing multiple protection fences on the reference plane below the operation platform 7, a protection structure is formed around the operation platform 7 after the multiple protection fences are connected to each other. By adjusting the contact positions of the head end of each protection fence with the protection surfaces of the adjacent protection fences, the size of the protection structure is changed, so as to facilitate adaptation to operation platforms 7 of different scales, and the positioning and installation of the protection fence are realized without depending on the operation platform, reducing the manufacturing cost of the protection equipment and improving the operation efficiency.

[0045] As Figures 2 - 3 shown, in one embodiment, the structures of the first protection fence 1, the second protection fence 2, the third protection fence 3, and the fourth protection fence 4 are the same;

[0046] The structure of the first protective fence 1 is as follows: It includes an upper frame 11, a protective surface is located on the upper frame 11, a first lower support 14 is provided below the end of the upper frame 11, a second lower support 15 is provided below the head end of the upper frame 11, a locking device 5 is provided on the upper frame 11, and two adjacent upper frames 11 are detachably connected through the locking device 5. The lower ends of the first lower support 14 and the second lower support 15 are in contact with the reference plane.

[0047] Specifically, the upper frame 11 is of a rectangular structure and includes at least two horizontally arranged cross bars 111 and two vertically arranged longitudinal bars 112. The cross bars 111 and the longitudinal bars 112 are connected to form a rectangular structure. Multiple connecting bars can be arranged between the longitudinal bars 112 to connect the two longitudinal bars 112 and enhance the stability of the structure of the upper frame 11.

[0048] Furthermore, universal wheels 17 are provided at the lower ends of both the first lower support 14 and the second lower support 15. The setting of the universal wheels 17 facilitates the relative movement after the connection between the protective fences is released. The universal wheels 17 have a locking function.

[0049] Furthermore, a protective net 13 is provided on the upper frame 11, which improves the protective effect and at the same time reduces the overall weight of the protective fence.

[0050] When the high-altitude protective fence is not in use, after the first protective fence 1, the second protective fence 2, the third protective fence 3, and the fourth protective fence 4 are disconnected, they can be placed separately, reducing the floor area during storage.

[0051] In order to enable the protective fence not to require additional support when placed separately, as Figures 1 - 5 shown, in another embodiment, the structure of the second lower support 15 includes a vertical support 151 fixedly connected to the head end of the upper frame 11. A horizontal support 153 is provided at the lower end of the vertical support 151. The horizontal support 153 is perpendicular to the vertical support 151, and the horizontal support 153 faces the outside of the protective structure.

[0052] The plane where the horizontal support 153 and the vertical support 151 are located is perpendicular to the protective surface of the upper frame 11, as Figure 5 shown.

[0053] The horizontal support 153 and the adjacent first lower support 14 are detachably connected through the locking device 5.

[0054] Specifically, the vertical support 151 is a rod-shaped structure with the same structure as the longitudinal bar 112 or is directly formed by the downward extension of the longitudinal bar 112. The horizontal support 153 is also a rod-shaped structure and is arranged in the horizontal direction; as Figure 2 shown, when the relative position between the first protective fence 1 and the third protective fence 3 needs to be changed, it is adjusted by changing the relative position between the locking device 5 on the first lower support 14 and the adjacent horizontal support 153.

[0055] Both the upper and lower parts of the guardrail are detachably connected by a locking device 5 to improve the stability of the overall structure of the high-altitude guardrail.

[0056] The second lower support 15 further includes a diagonal brace 152 in the shape of a rod structure, and the diagonal brace 152 is used to connect the end of the horizontal support 153 and the upper frame 11 to improve the overall strength of the second lower support 15.

[0057] The three-dimensional structure of the second lower support 15 not only facilitates the separate storage of the guardrail, but also increases the overall support area and support strength of the high-altitude fence.

[0058] Furthermore, an exit 12 is provided on the upper frame 11, and a climbing ladder 16 is provided on the second lower support 15, and the climbing ladder 16 corresponds to the exit 12. Specifically, the lower end of the climbing ladder 16 is connected to the end of both the diagonal brace 152 and the horizontal support 153 at the same time. An exit 12 can be provided on each of the first guardrail 1, the second guardrail 2, the third guardrail 3, and the fourth guardrail 4, or an exit 12 can be provided on the upper frame 11 of only one of them.

[0059] The provision of the climbing ladder 16 eliminates the need for separate climbing equipment, facilitates construction, and reduces operating costs.

[0060] As Figures 4 - 8 shown, in one embodiment, the locking device 5 is provided at the first end of the upper frame 11;

[0061] The structure of the locking device 5 includes a guiding portion 51 slidably mounted on the upper frame 11 and an extending portion 52 fixedly provided on the guiding portion 51. A limiting portion 53 is fixedly provided at the end of the extending portion 52, and the limiting portion 53 cooperates with the adjacent upper frame 11 to connect the first end of the upper frame 11 to the protective surface of the adjacent upper frame 11.

[0062] Specifically, the guiding portion 51 is a sleeve structure adapted to the longitudinal rod 112 and the vertical support 151, so that the locking device 5 can move up and down relative to the upper frame 11, thereby facilitating the connection and disconnection with the adjacent upper frame 11. As Figure 4 shown, in the figure, (a) is the disconnected state when adjusting the relative position of adjacent guardrails, and (b) is the connected state of the adjacent upper frame 11 after the adjustment is completed.

[0063] As Figures 4 - 8 shown, in another embodiment, the limiting portion 53 is plate-shaped, and a guiding channel adapted to the end face of the adjacent upper frame 11 is formed between the limiting portion 53 and the first end of the upper frame 11.

[0064] The locking device 5 and its installation position form a guiding channel that can move relative to the adjacent upper frame 11, and the orientations of the locking devices 5 between different guardrails are different, so as to adjust the contact position between the head end of the guardrail and the protective surface of the adjacent guardrail, and at the same time ensure that the distance between the head end of the guardrail and the protective surface remains unchanged. Through a simple connection structure, the size change of the protective structure after unlocking between the guardrails and the stability of the protective structure after locking between the guardrails are realized.

[0065] Two locking devices 5 can be arranged at the connection position of adjacent guardrails. As Figure 4 shown, the adjacent upper frames 11 are connected simultaneously from two positions above and below the upper frame 11.

[0066] In order to position the locking device 5, a locking structure can be arranged on the locking device 5 to prevent the locking device 5 from moving up and down.

[0067] As Figures 4 - 6 shown, in another embodiment, a blocking structure 6 is installed on the upper frame 11, and the blocking structure 6 is used to block the limiting part 53 from disengaging from the adjacent upper frame 11. Specifically, the blocking structure 6 is a blocking block detachably installed on the upper frame 11 by bolts, or it can be just a bolt.

[0068] When the high-altitude protective fence of this embodiment is installed:

[0069] All guardrails are placed on the reference plane in the unlocked state;

[0070] The second guardrail 2 and the fourth guardrail 4 are moved relative to each other to adjust the relative position, as Figure 3 shown;

[0071] The third guardrail 3 is moved to one side of the second guardrail 2 and the fourth guardrail 4, and then the three are fixedly connected through the locking device 5, and the blocking structure 6 is installed on the guardrail;

[0072] The first guardrail 1 is moved to the other side of the second guardrail 2 and the fourth guardrail 4, and then the three are fixedly connected through the locking device 5, and the blocking structure 6 is installed on the guardrail.

[0073] The disassembly process of the high-altitude protective fence is the reverse process of the above process.

[0074] The high-altitude protective fence in the embodiment of the present application provides a movable high-altitude protection structure, which can provide a high-altitude operation environment without hanging a safety rope and without installing a fixed protection net on the operation platform, can play a protective role and protect personal safety. At the same time, after the high-altitude protective fence is equipped with a climbing ladder 16, it also has a climbing function, replacing traditional climbing equipment, combining practical and protective functions, being convenient to assemble, and reducing the manufacturing cost and construction period.

[0075] The above description is an explanation of the present utility model, rather than a limitation thereof. For the scope defined by the present utility model, refer to the claims. Any form of modification may be made within the protection scope of the present utility model.
