[0002] Slope engineering, a construction term, refers to the transformation of natural and artificial slopes to meet engineering needs. According to the difference in the time of slope impact on the project, it can be divided into permanent slopes and temporary slopes; according to the relationship between slopes and projects, it can be divided into building foundation slopes, building adjacent slopes and extended slopes with less impact on buildings.

[0013] Preferably, an articulated block A is fixedly connected to the outer wall of the arc-shaped sleeve, a telescopic rod is hinged to the inner wall of the articulated block A, and an articulated block B is hinged to one end of the telescopic rod.

[0014] Preferably, the outer wall of the hinge block B is fixedly connected to the outer wall of the railing, and the outer wall of the telescopic rod is provided with a one-way air outlet. The outer wall of the telescopic rod is provided with a one-way air outlet.

[0015] Preferably, the interior of the telescopic rod is communicated with the interior of the one-way air outlet, and the interior of the telescopic rod is communicated with the interior of the one-way air inlet.

[0016] Preferably, the air inlet end of the one-way air outlet is communicated with the outside of the telescopic rod, and the air inlet end of the one-way air inlet is communicated with the inside of the telescopic rod.

[0017] The present invention provides a slope protection device for urban road traffic engineering construction. It has the following beneficial effects:

[0018] 1. The present invention provides a slope protection mechanism. When the baffle is hit by a stone, the arc plate B is squeezed. An internal spring is provided between the arc plate B and the arc plate A, so that the arc plate B slides on the inner wall of the arc sleeve and squeezes the internal spring to deform. At the same time, the baffle is also pushed by the stone to move toward the arc plate A together with the arc plate B. The arc plate A transfers the force received to the rotating shaft, and the rotating shaft transfers the force received to the entire fixed rod, so as to buffer the impact force of the rolling stone sliding down from a single place. The buffering force will also be evenly transmitted to each support column and the fixed seat through the fixed rod, so as to prevent the instantaneous impact on the support column and the railing caused by the rolling of the stone, and the problem of the railing and the support column being broken, and to avoid the situation that the bottom fixed seat is hit by a large stone and is uprooted.

[0019] 2. The present invention provides a slope protection mechanism to slow down the stones when they collide with the arc sleeve and the arc plate B, thereby preventing the stones from rushing to the road surface. It can also avoid the problem that all stones are blocked, resulting in the fixed seat and the support column always bearing a large pressure, which leads to their bending and fracture. It automatically blocks stones of different sizes in a targeted manner, which not only ensures that large stones are prevented from rushing into the road surface and causing road safety hazards, but also protects the stability of the fixed seat, support column and railing for long-term use, and avoids the problem of stones rolling directly into the road due to fracture.

[0020] 3. The present invention sets an auxiliary mechanism to achieve buffering of medium-sized stones by the impact of the arc sleeve and the arc plate B, and at the same time, the arc-shaped fixed plate on the other side of the rotating shaft is collided with the long connecting rod to drop, so as to complete the subsequent blocking of the medium-sized stones, which not only prevents the stones from rushing into the road surface, but also uses two layers of buffering to unload the impact of the stones on the railings in sections, thereby preventing the railings, fixing seats and supporting columns from bending and breaking. In addition, the same targeted protection measures can be given to large, medium and small stones with a simple and convenient structure, thereby maximizing the protection of the anti-fracture effect and long-term stable working effect of the fixing seats, supporting columns and railings.

[0021] 4. The present invention sets an auxiliary mechanism so that the one-way air inlet is stretched at a slower speed. Therefore, when the stone hits the arc sleeve and the arc plate B to lift up and make the arc fixed plate descend to block the stone, the arc fixed plate can maintain a descending blocking state for a long time, so that after the stone hits the arc sleeve and the arc plate B, it can still be stably blocked by the arc fixed plate at the rear, avoiding the stone from rolling down at a slow speed. After the arc sleeve, the arc plate B and the arc fixed plate return to their positions due to gravity, the arc fixed plate loses the blocking situation of the stone, further ensuring the interception stability of the arc fixed plate and the pull rod on the stone, reducing the occurrence of accidents.

[0022] 5. The present invention provides an auxiliary mechanism. When the railing is broken by a stone, the railing will be pushed to the ground by the stone after it is broken. At this time, the stone retaining plate originally on the top of the railing will be tilted up because the railing falls to the ground. At the same time, the stone retaining plate is pulled by the fixed seat through the pull rope. When the stone continues to roll, it will be further blocked by the tilted stone retaining plate, and the stone retaining plate is fixed and pulled by the fixed seat through the pull rope. Then, even in the extreme case that the railing is broken, the protective measure can still be implemented to prevent the stone from quickly rushing into the road surface, effectively avoiding the problem of road traffic being damaged.

[0023] 6. The present invention provides an auxiliary mechanism. Even if the railing is not broken but bent, the stone retaining plate on the top of the railing can still prevent the rolling stones from hitting the inclined and curved railing and rolling onto the inclined railing and passing over the railing, thereby avoiding the problem of stones rushing into the road surface as much as possible.

DETAILED DESCRIPTION

[0038] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a slope protection device for urban road traffic engineering construction, comprising a slope 2, a road surface 1 is arranged on one side of the slope 2, a fixing seat 5 is fixedly connected to the top of the road surface 1, a support column 6 is fixedly connected to the top of the fixing seat 5, a fixing rod 7 is fixedly connected to one side of the support column 6, a handrail 8 is fixedly connected to the outer wall of the fixing rod 7, and a slope protection mechanism 3 is arranged on the outer wall of the fixing rod 7;

[0039] The slope protection mechanism 3 comprises:

[0040] The rotating shaft 301 is a circular rod-shaped structure. The outer wall of the rotating shaft 301 is rotatably connected to the bottom of the fixed rod 7. The outer wall of the rotating shaft 301 is fixedly connected to the arc plate A302. The outer wall of the arc plate A302 is slidably connected to the arc sleeve 303. The rotating shaft 301 is used to drive the arc plate A302 to rotate.

[0041] Baffle 305, baffle 305 is a square plate structure, the outer wall of baffle 305 is fixedly connected with arc plate B304, the outer wall of arc plate B304 is slidably connected with the inner wall of arc sleeve 303, the inner wall of arc sleeve 303 is provided with a built-in spring, one end of the built-in spring is fixedly connected with one side of arc plate B304, and the other end of the built-in spring is fixedly connected with one side of arc plate A302, baffle 305 plays the role of blocking and supporting stones;

[0042] When in use, once a stone slides down the side slope 2, the stone will slide down to the railing 8 along the slope of the side slope 2 and be blocked by the railing 8, thereby preventing the stone from rolling down the side slope 2 onto the road.

[0043] Example 2: Please refer to Figure 1-9 On the basis of the first embodiment, the present invention provides a technical solution: an arc-shaped connecting plate 306 is fixedly connected to the outer wall of the rotating shaft 301 , and an arc-shaped fixing plate 307 is fixedly connected to one end of the arc-shaped connecting plate 306 .

[0044] The inner wall of the arc-shaped fixed plate 307 is fixedly connected with a long connecting rod 308, and the outer wall of the arc-shaped fixed plate 307 is fixedly connected with a pull rod 309, and the pull rod 309 is a round rod-shaped structure;

[0045] Once a stone rolls down to the railing 8, it will first contact the baffle 305. If the stone has a large diameter, it will be relatively high, and the front of the stone will directly hit the baffle 305. The baffle 305 will be squeezed by the impact of the stone and the curved plate B304 will be squeezed. There is an internal spring between the curved plate B304 and the curved plate A302, so that the curved plate B304 will slide on the inner wall of the curved sleeve 303 and squeeze the internal spring to deform. At the same time, the baffle 305 is also pushed by the stone and enters the curved plate A302 together with the curved plate B304. 02, the arc plate A302 transfers the force received to the rotating shaft 301, and the rotating shaft 301 transfers the force received to the entire fixing rod 7, so as to buffer the impact force of the rolling stone sliding down from a single place, and the buffering force will be evenly transmitted to each support column 6 and the fixing seat 5 through the fixing rod 7, so as to prevent the instantaneous impact of the stone rolling down on the support column 6 and the railing 8, and the railing 8 and the support column 6 from being broken, and to prevent the fixing seat 5 at the bottom from being uprooted by being hit by a large stone;

[0046] If the falling stone is small, the height of the stone is relatively short, and thus the height will be lower than the baffle 305. Once the height of the falling stone is lower than the baffle 305, the stone will not hit the baffle 305 when rolling down, but will hit the bottom of the arc plate B304 and the arc sleeve 303 below the baffle 305. Because the arc plate B304 and the arc sleeve 303 are arc-shaped surfaces, when hitting the bottom of the arc plate B304 and the arc sleeve 303, the arc sleeve 303 and the arc plate B304 will also be given an upward force, thereby driving the arc plate A302 and the rotating shaft 301 to rotate and lift, so that the arc plate A302, the arc sleeve 303, the arc sleeve 303 and the arc plate B304 are The curved plate B304 and the baffle plate 305 rise as a whole, and do not block the rolling stones, but slow down the stones when they collide with the curved sleeve 303 and the curved plate B304, so as to prevent the stones from rushing to the road surface. It can also prevent all the stones from being blocked, resulting in the fixed seat 5 and the support column 6 always bearing a large pressure, causing them to bend and break. It automatically blocks stones of different sizes in a targeted manner, which not only ensures that large stones are prevented from rushing into the road surface and causing road safety hazards, but also protects the stability of the fixed seat 5, the support column 6, and the railing 8 for long-term use, and avoids the problem of stones directly rolling into the road due to breakage.

[0047] Smaller stones will not touch the baffle 305, nor the bottom of the curved plate B304 and the curved sleeve 303, and will directly roll out from the bottom of the fixed rod 7. There are a large number of these small stones, which are harmless, so there is no need to block them. Blocking them for too long will increase the pressure on the fixed rod 7 and the railing 8.

[0048] When the arc plate A302, the arc sleeve 303, the arc plate B304 and the baffle plate 305 are pushed to rotate and lift together with the rotating shaft 301, the rotation and lifting of the rotating shaft 301 will also drive the arc connecting plate 306 on its outer wall to lift up, and when the arc connecting plate 306 is lifted up, it will drive the arc fixing plate 307 to extend to the other side of the rotating shaft 301 and show a trend of rotating and descending, so that the medium-sized stone will hit the arc sleeve 303 and the arc plate B304 and then collide with the descending arc fixing plate 307 again through the bottom of the fixing rod 7, and the stone will be blocked again by the arc fixing plate 307. Each arc fixing plate 307 is connected by a long connecting rod 308, and each arc fixing plate 307 is fixedly connected with a pull rod 309, so The pull rod 309 between each arc-shaped fixed plate 307 and the arc-shaped fixed plate 307 completes the automatic blocking of stones, so that the medium-sized stones will be buffered by the impact of the arc sleeve 303 and the arc plate B304, and the arc-shaped fixed plate 307 on the other side of the rotating shaft 301 will be collided and lowered with the long connecting rod 308 to complete the subsequent blocking of the medium-sized stones, which not only prevents the stones from rushing into the road surface, but also uses two layers of buffering to block and unload the impact of the stones on the railing 8 in sections, preventing the railing 8, the fixing seat 5, and the support column 6 from bending and breaking. In addition, the same targeted protection measures can be given to large, medium and small stones under the condition of simple and convenient structure, maximizing the protection of the anti-fracture effect of the fixing seat 5, the support column 6 and the railing 8 and the long-term stable working effect;

[0049] Example 3: Please refer to Figure 1-13 On the basis of the first and second embodiments, the present invention provides a technical solution: an auxiliary mechanism 4 is provided on the outer wall of the fixing seat 5, the auxiliary mechanism 4 includes a pull rope 401, one end of the pull rope 401 is fixedly connected to the outer wall of the fixing seat 5, and the other end of the fixing seat 5 is fixedly connected to the fixing rod 7 located above.

[0050] The outer wall of the arc sleeve 303 is fixedly connected with a hinge block A402, the inner wall of the hinge block A402 is hinged with a telescopic rod 403, and one end of the telescopic rod 403 is hinged with a hinge block B404.

[0051] The outer wall of the hinge block B404 is fixedly connected to the outer wall of the railing 8, and the outer wall of the telescopic rod 403 is provided with a one-way air outlet 405. The outer wall of the telescopic rod 403 is provided with a one-way air outlet 405.

[0052] The interior of the telescopic rod 403 is communicated with the interior of the one-way air outlet 405 , and the interior of the telescopic rod 403 is communicated with the interior of the one-way air inlet 406 .

[0053] The air inlet end of the one-way air outlet 405 is communicated with the outside of the telescopic rod 403, and the air inlet end of the one-way air inlet 406 is communicated with the inside of the telescopic rod 403;

[0054] When the arc sleeve 303 and the arc plate B304 are bumped and lifted, the arc fixed plate 307 will be driven to drop on the other side through the rotating shaft 301, and when the arc sleeve 303 is lifted, the hinge block A402 will be pushed to the telescopic rod 403 to shrink, and when the telescopic rod 403 shrinks, the air inside is discharged through the one-way air outlet 405, and when the stone rolls toward the arc fixed plate 307 through the arc sleeve 303 and the bottom of the arc plate B304, the arc sleeve 303 and the arc plate B304 will be resisted by the stretching of the telescopic rod 403 when they fall due to gravity. When the telescopic rod 403 is stretched, air enters through the one-way air inlet 406, and the one-way air inlet 406 has a small diameter, so the one-way air inlet 406 is small. The air port 406 is stretched at a slow speed, so when the stone hits the arc sleeve 303 and the arc plate B304 to lift up and the arc fixed plate 307 is lowered to block the stone, the arc fixed plate 307 can maintain a long-term descending blocking state, so that after the stone hits the arc sleeve 303 and the arc plate B304, it can still be stably blocked by the arc fixed plate 307 at the rear, avoiding the slow rolling speed of the stone. After the arc sleeve 303, the arc plate B304 and the arc fixed plate 307 return to their original positions due to gravity, the arc fixed plate 307 loses the blocking of the stone, further ensuring the stability of the arc fixed plate 307 and the pull rod 309 in intercepting the stone, reducing accidents;

[0055] However, if a stone is too large and has too great an impact force, and directly hits the baffle plate 305, and fails to unload the force and continues to rush towards the railing 8, thereby breaking the railing 8, the railing 8 will be pushed to the ground by the stone after breaking. At this time, the stone baffle plate 407 originally on the top of the railing 8 will be tilted up because the railing 8 has fallen to the ground. At the same time, the stone baffle plate 407 is pulled by the fixing seat 5 through the pull rope 401. Therefore, when the stone continues to roll, it will be further blocked by the tilted stone baffle plate 407, and the stone baffle plate 407 is fixed and pulled by the fixing seat 5 through the pull rope 401, thereby achieving a protective measure to prevent stones from quickly rushing into the road surface even in the extreme case that the railing 8 is broken, thereby effectively avoiding the problem of road traffic being damaged.

[0056] Even if the railing 8 is not broken but bent, the stone retaining plate 407 on the top of the railing 8 can still prevent the rolling stone from hitting the inclined and curved railing 8 and rolling onto the inclined railing 8 and passing over the railing 8, thereby avoiding the problem of stones rushing into the road surface as much as possible.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
