In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0028] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] In this embodiment, if Figure 1 and Figure 5As shown, a wind barrier comprises a column 2, the lower end of the column 2 is mounted on a base 6 by embedded bolts 1, a bottom windshield 3 is arranged between the lower ends of the two columns 2, and a plurality of windshields 4 are arranged above the bottom windshield 3. Preferably, the bottom windshield 3 is in an inverted L shape. Specifically, the bottom windshield 3 is in an inverted L shape so that the outer bolts can be placed on the inner side of the track, which is convenient for subsequent maintenance and overhaul. The end of the windshield 4 is snap-fitted with a head 11, and a buffer rubber tube 8 is arranged on the outer side of the head 11, and the buffer rubber tube 8 is located between the head 11 and the column 2. By snap-fitting the head 11 on the end of the windshield 4 to make it flexibly connected, and then inserting the two ends of the bottom windshield 3 and the windshield 4 into the column 2, and arranging a buffer rubber tube 8 on the outer side of the head 11 so that it is located between the head 11 and the column 2, compared with the traditional bolt connection, it can effectively avoid stress concentration at the node, reduce the risk of fatigue damage, and thus improve the overall fatigue resistance. In this embodiment, a plurality of ventilation holes 18 are provided on the surfaces of the bottom windshield 3 and the windshield 4 .
[0030] Further, such as Figure 6 As shown, the cross section of the windshield 4 is M-shaped, and the upper and lower ends of the windshield 4 are provided with a snap interface 13, and the head 11 is snap-fitted into the snap interface 13. Specifically, the head 11 is snap-fitted to the end of the windshield 4 to make it a flexible connection. Compared with the traditional bolt connection, it can effectively avoid stress concentration at the node, thereby improving the overall fatigue resistance. Further, as Figure 7 As shown, the upper and lower ends of the head 11 are provided with a clamping plate 14, and the clamping plate 14 is provided with a clamping block 15. The clamping block 15 is buckled and installed in the clamping interface 13. Preferably, the clamping block 15 is U-shaped. The left and right ends of the head 11 are provided with a baffle 16, and a plurality of fixing holes 17 are opened on the baffle 16. Specifically, since the windshield 4 is a thin plate shell structure, its rigidity is weak. When it is subjected to horizontal wind load, in addition to horizontal deformation, the plate body will also produce a large deformation in the vertical direction due to the lack of upper and lower constraints. Therefore, the windshield 4 is constrained by the clamping plate 14 and the baffle 16, thereby improving the overall rigidity and strength of the windshield 4; at the same time, the buffer rubber tube 8 is installed on the head 11 by rivets. In this embodiment, the cross-section of the windshield 4 is M-shaped, that is, the upper and lower surfaces of the windshield 4 are flanged, so that the support surface between the column 2 can be increased, the deformation can be reduced, and the rigidity can be improved.
[0031] In this embodiment, if Figure 4 As shown, the column 2 includes a bottom plate and an H-shaped steel 10. The bottom plate is mounted on the base 6 by embedded bolts 1. The H-shaped steel 10 is welded on the bottom plate. A slot is provided on the inner side of the H-shaped steel 10. The bottom windshield 3 and the two ends of the windshield 4 are inserted into the slot. Preferably, an anti-drop beam locking bolt 12 is installed on the H-shaped steel 10. The anti-drop beam locking bolt 12 is used to fix the windshield 4. Further, as Figure 3 As shown, a mounting hole 19 is provided on the column 2, and an anti-falling locking bolt 9 is installed in the mounting hole 19.
[0032] In this embodiment, if Figure 2 As shown, a cover plate 5 is installed on the top of the column 2 through a locking bolt 7.
[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
