A grid-type highway slope protection structure

Abstract

The present invention relates to the technical field of slope protection, and discloses a grid-type highway slope protection structure, including a protection mechanism. There is a protection space outside the protection mechanism, which is used to protect passing vehicles. There is an extension mechanism located outside the protection mechanism, which is used to operate the extension mechanism to expand the protection surface. There is an auxiliary mechanism installed outside the extension mechanism, which is used to operate the auxiliary mechanism to protect the protection mechanism. When a rolling stone falls off and rolls at a highway slope, the rolling stone will first come into contact with the inclined surface of the baffle, thereby reducing the impact force of the rolling stone and preventing the device from tilting due to excessive impact force caused by the rolling of the rolling stone. When the baffle is impacted, the baffle drives the round block to move, the round block drives the sliding shell to move, and the sliding shell drives the roller frame to roll and displace along the ground. At this time, the inclined surface of the baffle gradually becomes vertical, improving the anti-impact surface of the rolling stone.

Description

Technical Field

[0001] The present invention relates to the technical field of slope protection, and particularly to a grid-type highway slope protection structure. Background Technique

[0002] The grid-type highway slope protection mechanism is mainly used in slope areas such as highways, railways, and mountain roads, especially those with a high risk of landslides or prone to soil erosion. This structure has a simple design, convenient construction, low cost, and strong adaptability and maintainability, and is widely used in mountainous areas, hilly areas, and other areas with complex geological conditions.

[0003] Existing slope protection nets usually use steel wires to stretch and reinforce the slope protection net frame. When a rolling stone impacts the slope protection net frame, the slope protection net frame may tilt, affecting the protection effect of the slope protection net frame on the rolling stone. Summary of the Invention

[0004] The purpose of the present invention is to provide a grid-type highway slope protection structure to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is a grid-type highway slope protection structure, including a protection mechanism. The protection mechanism includes a protection shell and a connecting plate. There are two protection shells and two connecting plates. A first protection net is fixedly connected between the two protection shells, and a second protection net is fixedly connected between the two connecting plates; the protection shell and the connecting plate are slidably connected; the protection mechanism further includes:

[0007] An auxiliary mechanism. The auxiliary mechanism includes a fastening member. The fastening member includes a spherical rod fixedly connected to the center of the top of the first protection net. A steel wire rope is fixedly connected to the side wall of the top end of the spherical rod, and a clamping anchor rod is fixedly connected to the end of the steel wire rope away from the spherical rod;

[0008] The auxiliary mechanism further includes a cross bar. The cross bar is arranged on the top of the connecting plate through a transmission structure, and a special-shaped roller is rotatably connected to the outer wall of the middle end of the cross bar;

[0009] The protection mechanism further includes a rolling member for blocking rolling stones. The rolling member includes a baffle plate fixedly connected to a roller frame, and the roller frame is connected to the connecting plate through an extension mechanism. When the baffle plate is impacted by a rolling stone, the roller frame drives the roller to roll along the ground, and drives the second protective net to move upward through the extension mechanism. When the second protective net moves upward, it drives the cross bar to descend through the transmission structure, and the cross bar drives the special-shaped roller to descend. When the special-shaped roller descends, it contacts the top of the steel wire rope and presses down on the steel wire rope.

[0010] Further, the extension mechanism includes:

[0011] A first rotating rod rotatably connected to the top end of the protective shell. One end of the outer wall of the first rotating rod is slidably connected to a sliding shell, and the roller frame penetrates and is rotatably connected to the bottom side wall of the sliding shell.

[0012] And a second rotating rod rotatably connected to one side of the middle end of the sliding shell. One end of the second rotating rod is rotatably connected to a slider, and the middle end of the slider is slidably connected to the inner wall of the protective shell. The end of the slider away from the second rotating rod is fixedly connected to the connecting plate.

[0013] Further, the first rotating rod is rotatably connected to the protective shell through a concave shell on one side of the top end of the protective shell, and both sides of the inner wall of the concave shell are rotatably connected to the first rotating rod.

[0014] Further, limiting holes are respectively formed on both sides of the outer wall of the protective shell, and both ends of the slider are respectively slidably connected to the inner walls of the limiting holes.

[0015] Further, a circular block is fixedly connected to one side of the outer wall of the sliding shell close to the roller frame. There are two circular blocks, and the baffle plate is fixedly connected between the two circular blocks.

[0016] Further, one end of the first rotating rod away from the protective shell is fixedly connected to a spring, and one end of the spring is fixedly connected to the bottom of the inner wall of the sliding shell.

[0017] Further, the transmission structure includes a concave block and a hollow rotating bar; the concave block is fixedly connected to one side of the top end of the connecting plate; both sides of one end of the hollow rotating bar are rotatably connected to both sides of the inner wall of the concave block;

[0018] A clamping block is fixedly connected to one side of the outer wall of the concave shell, and one end of the outer wall of the clamping block is slidably connected to the inner wall of the hollow rotating bar, and the cross bar is fixedly connected between the two hollow rotating bars.

[0019] Further, one side of the hollow rotating bar is hollowed out.

[0020] Further, a positioning mechanism is further included. The positioning mechanism includes a semicircular extrusion strip in contact with one side of the outer wall of the first protective net. A strip-shaped concave shell is fixedly connected to the side of the semicircular extrusion strip away from the first protective net. Two ends of one side of the inner wall of the strip-shaped concave shell are respectively rotatably connected to a first rotating plate. One end of the first rotating plate away from the strip-shaped concave shell is rotatably connected to a vertical plate. The inner wall of the top end of the vertical plate is rotatably connected to the outer wall of one end of the cross bar.

[0021] Further, the positioning mechanism further includes second rotating plates rotatably connected to two ends of the strip-shaped concave shell close to the first rotating plate. One end of the second rotating plate away from the strip-shaped concave shell is rotatably connected to a cross plate. Three special-shaped anchor rods are fixedly connected to the bottom of the cross plate.

[0022] (2) In the present invention, since the spherical rod, the steel wire rope, and the positioning anchor rod are fixedly arranged, at this time, the positioning anchor rod is inserted into the ground, making the steel wire rope in a taut state, thereby firmly fixing the first protective net connected to the spherical rod, preventing the device from tilting to the side away from the highway slope after being impacted by rolling stones. When the connecting plate moves upward, the connecting plate drives the concave block to move upward. Since the concave shell and the clamping block are fixedly arranged, at this time, the clamping block is in a stationary state. Limited by the clamping block, the concave block drives the hollow rotating bar to slide along the outer wall of the clamping block, making the hollow rotating bar in a descending motion. The hollow rotating bar drives the cross bar to descend, and the cross bar drives the special-shaped roller to descend. When the special-shaped roller descends, it will come into contact with the top of the steel wire rope, pressing down on the steel wire rope, making the steel wire rope in a taut state. As the tension of the steel wire rope increases, the whole of the first protective net will shift towards the highway slope, further improving the firmness of the first protective net.

[0023] (3) In the present invention, when the cross bar descends, the cross bar drives the vertical plate to descend, and the vertical plate drives the first rotating plate to descend. At this time, the vertical plate and the second rotating plate gradually approach, so that the first rotating plate and the second rotating plate will drive the strip-shaped concave shell to approach the first protective net. The strip-shaped concave shell drives the semicircular extrusion strip to move. During the movement of the semicircular extrusion strip, it will squeeze the middle side wall of the first protective net, thereby preventing the steel wire rope from indirectly driving the first protective net to tilt excessively, slightly resisting the first protective net, and improving the stability of the first protective net. And when the semicircular extrusion strip no longer exerts too much squeezing force on the first protective net, the vertical plate, the first rotating plate, the strip-shaped concave shell, the semicircular extrusion strip, and the second rotating plate will overall exert a downward pressure on the top of the cross plate. The cross plate is slightly pressed downward, and the cross plate drives the special-shaped anchor rod to fall, making the special-shaped anchor rod insert deeper into the ground, thereby improving the stability of the first protective net against the sliding of rolling stones, reducing the phenomenon that the whole device shakes and tilts, and improving the quality of protection.

[0024] Of course, it is not necessary for any product implementing the present invention to achieve all of the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The protection mechanism 1 includes a protection shell 11 and a connecting plate 24. There are two protection shells 11 and two connecting plates 24. A first protection net 12 is fixedly connected between the two protection shells 11, and a second protection net 25 is fixedly connected between the two connecting plates 24; the protection shell 11 and the connecting plate 24 are slidably connected; the protection mechanism 1 includes:

[0043] A sliding member, which is fixedly arranged with the protection shell 11;

[0044] A rolling member, which is rotatably arranged outside the sliding member and is used to block rolling stones;

[0045] The sliding member includes a first protection net 12 fixedly connected between the two protection shells 11. One side of the top of the protection shell 11 is fixedly connected with a concave shell 19. Both sides of the inner wall of the concave shell 19 are rotatably connected with a first rotating rod 13, and the outer wall of one end of the first rotating rod 13 is slidably connected with a sliding shell 14;

[0046] Among them, through the setting of the rolling member, rolling stones can be blocked.

[0047] The extension mechanism 2 includes:

[0048] A rotating member, which is rotatably arranged with the sliding shell 14;

[0049] A protective member, which is fixedly arranged on the outer wall of the rotating member and is used to expand the protective surface;

[0050] The rotating member includes a second rotating rod 21 rotatably connected to one side of the middle end of the sliding shell 14. One end of the second rotating rod 21 is rotatably connected with a slider 23. Limiting holes 22 are respectively opened on both sides of the outer wall of the protective shell 11. The middle end of the slider 23 is slidably connected to the inner wall of the protective shell 11, and both ends of the slider 23 are slidably connected to the inner walls of the limiting holes 22;

[0051] Among them, through the setting of the protective member, the expansion of the protective surface is realized.

[0052] The auxiliary mechanism 3 includes:

[0053] A fastening member, which is fixedly arranged with the first protective net 12;

[0054] The fastening member includes a spherical rod 36 fixedly connected to the center of the top of the first protective net 12. A steel wire rope 37 is fixedly connected to the side wall of the top end of the spherical rod 36. One end of the steel wire rope 37 far from the spherical rod 36 is fixedly connected with a clamping anchor rod 38. The bottom end of the clamping anchor rod 38 is inserted deep into the ground to anchor the device; The auxiliary mechanism 3 further includes a cross bar 34, which is arranged on the top of the connecting plate 24 through a transmission structure. An irregular roller 35 is rotatably connected to the outer wall of the middle end of the cross bar 34; In some embodiments, the transmission structure includes a concave block 31 and a hollow rotating bar 33; The concave block 31 is fixedly connected to one side of the top end of the connecting plate 24; Both sides of one end of the hollow rotating bar 33 are rotatably connected to both sides of the inner wall of the concave block 31; A clamping block 32 is fixedly connected to one side of the outer wall of the concave shell 19. One end of the outer wall of the clamping block 32 is slidably connected to the inner wall of the hollow rotating bar 33. A cross bar 34 is fixedly connected between the two hollow rotating bars 33. One side of the hollow rotating bar 33 is hollowed out. In this structure, the cross bar 34 drives the irregular roller 35 to descend. When the irregular roller 35 descends, it will contact the top of the steel wire rope 37 and press down on the steel wire rope 37 to make the steel wire rope 37 in a taut state. The tension of the steel wire rope 37 becomes larger, which will cause the whole of the first protective net 12 to shift towards the highway slope, further improving the firmness of the first protective net 12.

[0055] Among them, through the setting of the extrusion member, the stability of the fastening member is realized.

[0056] During the movement of the extrusion semi-circular strip 44, it will extrude the middle side wall of the first protective net 12, thereby preventing the steel wire rope 37 from indirectly driving the first protective net 12 to tilt excessively, slightly resisting the first protective net 12, improving the stability of the first protective net 12. The positioning mechanism 4 includes:

[0057] An auxiliary part and a positioning part. The positioning part is rotatably arranged on the side wall of the auxiliary part and is used for strengthening the ground.

[0058] The auxiliary part includes an extrusion semi-circular strip 44 that is in contact with one side of the outer wall of the first protective net 12. One side of the extrusion semi-circular strip 44 away from the first protective net 12 is fixedly connected to a strip-shaped concave shell 43. At both ends of one side of the inner wall of the strip-shaped concave shell 43, a first rotating plate 42 is respectively rotatably connected. One end of the first rotating plate 42 away from the strip-shaped concave shell 43 is rotatably connected to a vertical plate 41. The inner wall of the top end of the vertical plate 41 is rotatably connected to the outer wall of one end of the cross bar 34.

[0059] Among them, through the setting of the positioning part, the ground can be firmly fixed.

[0060] The rolling part includes a roller frame 16 that penetrates and is rotatably connected to the bottom side wall of the sliding shell 14. On one side of the outer wall of the sliding shell 14 close to the roller frame 16, a round block 17 is fixedly connected. There are two round blocks 17. A baffle 18 is fixedly connected between the two round blocks 17. When the rolling stones on the highway slope fall off and roll, the rolling stones will first come into contact with the inclined surface of the baffle 18, thereby reducing the impact force of the rolling stones and preventing the device from tilting due to the excessive impact force caused by the rolling of the rolling stones. One end of the first rotating rod 13 away from the concave shell 19 is fixedly connected to a spring 15. One end of the spring 15 is fixedly connected to the bottom of the inner wall of the sliding shell 14. The sliding shell 14 drives the roller frame 16 to roll and displace along the ground. At this time, the inclined surface of the baffle 18 gradually becomes vertical, expanding the anti-impact surface of the rolling stones.

[0061] The protective part includes a connecting plate 24 fixedly connected to the end of the slider 23 away from the second rotating rod 21. A second protective net 25 is fixedly connected between the two connecting plates 24. There is one second protective net 25. The connecting plate 24 drives the second protective net 25 to move upward. During the upward movement of the second protective net 25, it can expand the protective surface of the first protective net 12 and improve the blocking effect on the rolling stones.

[0062] The positioning member includes second rotating plates 45 rotatably connected to both ends of the strip-shaped concave housing 43 near one side of the first rotating plate 42. One end of the second rotating plate 45 away from the strip-shaped concave housing 43 is rotatably connected to a cross plate 46. Three special-shaped anchor rods 47 are fixedly connected to the bottom of the cross plate 46. The vertical plate 41, the first rotating plate 42, the strip-shaped concave housing 43, the extrusion semi-circular strip 44, and the second rotating plate 45 will apply a downward pressure on the top of the cross plate 46 as a whole. The cross plate 46 is slightly pressed downward, and the cross plate 46 drives the special-shaped anchor rods 47 to fall, so that the special-shaped anchor rods 47 are inserted deeper into the ground, thereby improving the stability of the first protective net 12 against the rolling of rolling stones, reducing the phenomenon of the overall device shaking and tilting, and improving the quality of protection.

[0063] During use, when the rolling stones at the highway slope fall off and roll, the rolling stones will first come into contact with the inclined surface of the baffle 18, thereby reducing the impact force of the rolling stones and preventing the impact force caused by the rolling of the rolling stones from being too large and causing the device to tilt. When the baffle 18 is impacted, the baffle 18 drives the round block 17 to move, the round block 17 drives the sliding housing 14 to move, and the sliding housing 14 drives the roller frame 16 to roll and displace along the ground. At this time, the inclined surface of the baffle 18 gradually becomes vertical, expanding the anti-impact surface of the rolling stones. And due to the setting of the concave housing 19, the sliding housing 14 drives the first rotating rod 13 to rotate around the concave housing 19. At this time, the first rotating rod 13 gradually slides into the interior of the sliding housing 14. At the same time, limited by the protective housing 11, the sliding housing 14 will drive the second rotating rod 21 to move, the second rotating rod 21 drives the slider 23 to move upward along the inner wall of the protective housing 11, the slider 23 drives the connecting plate 24 to move upward, and the connecting plate 24 drives the second protective net 25 to move upward. During the upward movement of the second protective net 25, it can expand the protective surface of the first protective net 12 and improve the blocking effect on the rolling stones.

[0064] Since the spherical rod 36, the steel wire rope 37, and the positioning anchor rod 38 are fixedly arranged, at this time, the positioning anchor rod 38 is inserted into the ground, making the steel wire rope 37 in a taut state, thereby fixing the first protective net 12 connected to the spherical rod 36, preventing the device from tilting away from the highway slope after being impacted by rolling stones. When the connecting plate 24 moves upward, the connecting plate 24 drives the concave block 31 to move upward. Since the concave shell 19 and the clamping block 32 are fixedly arranged, at this time, the clamping block 32 is in a stationary state. Limited by the clamping block 32, the concave block 31 drives the hollow rotating bar 33 to slide along the outer wall of the clamping block 32, making the hollow rotating bar 33 in a descending motion. The hollow rotating bar 33 drives the cross bar 34 to descend, and the cross bar 34 drives the special-shaped roller 35 to descend. When the special-shaped roller 35 descends, it will contact the top of the steel wire rope 37, pressing down on the steel wire rope 37, making the steel wire rope 37 in a taut state. As the tension of the steel wire rope 37 increases, the entire first protective net 12 will shift towards the highway slope, further improving the firmness of the first protective net 12.

[0065] When the cross bar 34 descends, the cross bar 34 drives the vertical plate 41 to descend, and the vertical plate 41 drives the first rotating plate 42 to descend. At this time, the vertical plate 41 and the second rotating plate 45 gradually approach, causing the first rotating plate 42 and the second rotating plate 45 to drive the strip-shaped concave shell 43 to approach the first protective net 12. The strip-shaped concave shell 43 drives the extrusion semi-circular strip 44 to move. During the movement of the extrusion semi-circular strip 44, it will squeeze the middle side wall of the first protective net 12, thereby preventing the steel wire rope 37 from indirectly driving the first protective net 12 to tilt excessively, slightly resisting the first protective net 12, and improving the stability of the first protective net 12. And when the extrusion semi-circular strip 44 no longer exerts too much squeezing force on the first protective net 12, the vertical plate 41, the first rotating plate 42, the strip-shaped concave shell 43, the extrusion semi-circular strip 44, and the second rotating plate 45 will collectively exert a downward pressure on the top of the cross plate 46. The cross plate 46 is slightly pressed downward, and the cross plate 46 drives the special-shaped anchor rod 47 to fall, making the special-shaped anchor rod 47 penetrate deeper into the ground, thereby improving the stability of the first protective net 12 against the sliding of rolling stones, reducing the phenomenon of the overall device shaking and tilting, and improving the quality of protection.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification.
