Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a slope protection mechanism. Background Art

[0002] When mining on some ore slopes, there will be various slopes. Among these slopes, many are exposed slopes and are very likely to cause landslides due to slope collapse. In order to prevent construction landslides or some objects rolling down the slope and causing injuries to people, protective nets are usually set up on the slopes to reinforce the slopes. However, this method can only prevent the surface soil of the slope from sliding off, and cannot reinforce the slope, so more people will choose to install slope protection frames.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment: A slope protection mechanism, such as Figure 1-Figure 6 As shown, it includes a mounting base 1, a mounting shaft 2, a slope protection net 3, positioning pins 4 and a telescopic net 5. There are annular sleeves on both ends of the top of the mounting base 1. The mounting shaft 2 is installed between the two annular sleeves of the mounting base 1. The slope protection net 3 is rotatably mounted on both ends of the mounting shaft 2 through the annular sleeves on both sides. The slope protection net 3 is slidably connected to the telescopic net 5. Positioning pins 4 are respectively provided at the two diagonals on the rear side of the slope protection net 3 and below the four diagonals of the telescopic net 5. When workers are working in mines, there are often gravels on the slope surface, which are easy to slide down, affecting not only the workers' work but also their life, health and safety. The slope protection mechanism is placed on the slope surface, and the mounting base 1 is reinforced by two pairs of circular through holes on the left and right sides of the mounting base 1 in combination with long screws. According to the different slope inclinations, the angles between the slope protection net 3 and the telescopic net 5 and the mounting base 1 are adjusted through the mounting shaft 2, so that the slope protection net 3 and the telescopic net 5 are parallel to the slope surface, and are fixed by six positioning nails 4 under the corners of the slope protection net 3 and the telescopic net 5. A slide groove is provided in the telescopic net 5, and the slope protection net 3 slides in the slide groove of the telescopic net 5. According to the different slope areas, the telescopic net 5 is adjusted by sliding up and down, thereby adjusting the coverage area to achieve the best coverage and protection effect.

[0023] like Figure 2-Figure 6As shown, it also includes a first blocking plate 6. When the first blocking plates 6 are respectively arranged above the rear cross bar of the slope protection net 3 and above the rear cross bar of the telescopic net 5, the debris sliding down from the top of the slope can be blocked. When the debris sliding down from the top of the slope is large, it also includes a second blocking plate 7 and a limit block 12. The second blocking plate 7 is arranged on the mounting shaft 2 and is rotatably connected to the mounting shaft 2. Limit blocks 12 are arranged on both sides of the top of the mounting base 1. The limit blocks 12 are closely close to the second blocking plate 7 and are blocked by the second blocking plate 7 with a larger area. In order to prevent the second blocking plate 7 from rotating at any angle, the second blocking plate 7 is fixed on the left and right sides of the mounting base 1. The two upper limit blocks 12 limit the rotation angle of the second blocking plate 7. The bottom of the limit block 12 is fixed to the mounting base 1 by screws. The triangle has stability. The limit block 12 is in the shape of a triangular prism as a whole, and also includes an elastic member 13 and a buffer plate 14. Elastic members 13 are evenly arranged on the back of the second blocking plate 7. The elastic members 13 are springs. There are twelve of them and they are evenly spaced. The other end of the spring is connected to the buffer plate 14. When larger gravel slides down, the instantaneous impact force on the second blocking plate 7 is effectively reduced. When the falling gravel is larger and the gravel in different directions also slides toward the second blocking plate 7, it also includes a guide The guide rod 8 and the telescopic plate 9, the second blocking plate 7 are provided with guide rods 8 on the upper and lower sides, and the telescopic plates 9 are slidably connected to the upper and lower guide rods 8 on the same side. The telescopic plate 9 is located in front of the second blocking plate 7. The left front of the left telescopic plate 9 is partially cut off, and the right rear of the right telescopic plate 9 is partially cut off. The punching positions of the two telescopic plates 9 are aligned up and down, and the cut parts are symmetrical and complementary. The telescopic plate 9 is moved along the guide rod 8 to expand the blocking area. A warning sign 10 is provided in the middle of the front of the telescopic plate 9 to warn people at a distance. When the slope area to be protected is large, multiple slope protection mechanisms of this invention can be placed. The right side of the telescopic plate 9 of one slope protection mechanism is interlocked with the left side of the telescopic plate 9 of another slope protection mechanism, and fixed at the through hole by screws and nuts. For further reinforcement, a connecting block 11 is also included. Four through holes are punched on the connecting block 11. A connecting block 11 is provided on each of the left and right sides of the mounting base 1. The bottom surface of the left connecting block 11 is coplanar with the bottom surface of the mounting base 1, and the upper surface of the right connecting block 11 is coplanar with the upper surface of the mounting base 1. The connecting blocks 11 installed on the mounting base 1 are also interlocked and fixed, so that multiple slope protection mechanisms can be fixed together to achieve a protection effect in a larger slope range.

[0024] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
