The second concrete embodiment:
in this embodiment, on the basis of the triangular protective frame in the first embodiment, the protective frame further includes a deformable protective assembly.
Wherein, but deformation protection component can produce deformation in certain extent.
In particular, the deformable shield assembly is an arched door-shaped structure. The arch-type structure includes a strip-shaped guard band 7 and strip-shaped guard bands 8 connected to both ends of the arc-shaped guard band, as shown in fig. 9. Because the strip mine side slope is soft rock, has the possibility of deformation, is used for the strip mine side slope with this protective structure after, the side slope inevitable still can take place certain extent deformation, and the arc protecting band can produce deformation gliding, slides to the fixed point department that supports the protecting component, and triangle-shaped's support protecting component just can produce the supporting role to the arc protecting band, prevents that the arc protecting band from further gliding.
It is worth noting that when the deformable protection assembly is of an arched door-shaped structure, due to the problem of the spacing angle between the corresponding groove and the corresponding convex column in the connecting node, the machining angle of the arc-shaped protection belt after installation needs to be matched with the connecting node. Or the spacing of the grooves and posts in the connecting nodes may be adjusted. In addition, the two strip-shaped guard bands are not necessarily straight, and may be obliquely arranged according to the problem of limiting the angle after assembly.
The connecting node of the triangular supporting and protecting component also needs to be composed of three ring bodies, convex columns are distributed below the upper ring body, a groove is formed in the upper surface of the middle ring body, the convex columns are distributed on the lower surface of the middle ring body, the depth of the groove cannot penetrate through the ring bodies, and the thickness of the groove is half or more than half of the thickness of the ring bodies; the upper surface of the ring body positioned below is distributed with a groove. Therefore, the three ring body shoes rack can meet the requirement that the node can fix and connect the three protection belts.
The third concrete example:
in this embodiment, on the basis of the triangular protective frame in the first embodiment, a variable protective assembly is further included.
Specifically, the deformable protection component is of a fold line structure; the zigzag-shaped structure is formed by connecting at least three strip-shaped protective bands 8, as shown in fig. 10. Because the strip mine side slope is soft rock, the deformation possibility exists, after the protective structure is used for the strip mine side slope, the side slope can inevitably deform within a certain range, the strip-shaped protective belt positioned in the middle can deform and slide down to the fixed point of the supporting protective assembly, and the triangular supporting protective assembly can support the strip-shaped protective belt in the middle to prevent the strip-shaped protective belt from further sliding down.
In this embodiment, the connection node located in the triangular support protection component also needs to be composed of three ring bodies, which is the same as the case of the second embodiment, so that the mutual shoe rack of the three ring bodies can meet the requirement that the node can fix and connect the three protection belts.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
