Abstract

This utility model discloses a slope anti-slide device for highways, belonging to the field of geotechnical engineering technology. Its key technical features include a slope support column, with a protective adjustment integrated mechanism movably connected to the bottom of the column. An elastic connection mechanism is movably connected to the outer side of the slope support column, and a hanging ring is fixedly connected to the outer side of the elastic connection mechanism. A protective net is hinged to the outer side of the hanging ring. The device can be configured by setting a fixed base in a long strip shape, with the slope support column rotatably connected to one end of the fixed base. A sliding rail on the rear half of the fixed base and a sliding block with a threaded sleeve are used. The distance between the sliding block and the column is adjusted using an adjusting screw. Combined with a self-resetting bidirectional telescopic damper with a rotating component between the sliding block and the slope support column, a triangular-like stable structure is formed. This allows for fine-tuning of the slope support column's angle from 0 to 40 degrees towards the slope to adapt to the slope, thus solving the problem of repeated adjustments and installations required under the original fixed connection where the column angle did not match the slope.

Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering technology, and in particular to a device for preventing landslides on highway slopes. Background Technology

[0002] Highway slopes are prone to landslides due to factors such as topography, rainfall, and geological structure, threatening traffic safety and surrounding infrastructure. Traditional anti-slip measures such as retaining walls and anchors have limited adaptability and insufficient long-term stability. Therefore, there is an urgent need to develop efficient and reliable anti-slip devices.

[0003] In existing technologies, a section of the landslide prevention structure is typically constructed by two slope pillars with their inclined sides facing the non-slope side and a resilient protective net. However, during installation, because the slope pillars and the fixed base are in a fixed connection state, in order to ensure that the slope of the slope pillars in their normal state matches the slope gradient, there is a problem of needing to repeatedly adjust the angle and reinstall. In addition, although the existing protective net has the ability to resist deformation and toughness, it is usually installed by hinged connection between the net and the outside of the slope pillar through hanging rings. However, the hanging rings of the slope pillars are usually rigidly connected to the outer wall of the slope pillars. Therefore, when the protective net is impacted, the hanging rings on the outside of the slope pillars are very likely to collapse.

[0004] Therefore, a landslide prevention device for highway slopes is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a highway slope anti-slip device that can solve the problems of low installation and commissioning efficiency and weak impact resistance of existing hanging rings and protective nets.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highway slope anti-slip device, comprising a slope column, a protective adjustment integrated mechanism movably connected to the bottom of the slope column, an elastic connection mechanism movably connected to the outer side of the slope column, a hanging ring fixedly connected to the outer side of the elastic connection mechanism, a protective net hinged to the outer side of the hanging ring, the protective adjustment integrated mechanism comprising a fixed base, the slope column rotatably connected to the top of the fixed base, a sliding rail fixedly connected to the rear side of the fixed base, a sliding block slidably connected to the inner side of the sliding rail, rotating parts fixedly connected to the sliding block and the opposite side of the slope column, a self-resetting bidirectional telescopic damper rotatably connected to the inner side of the rotating part, and the two ends of the self-resetting bidirectional telescopic damper rotatably connected to the inner sides of the two rotating parts respectively, and an adjustment component movably connected to the outer side of the sliding block.

[0007] Preferably, the elastic connection mechanism includes a hollow fixing block, which is fixedly connected to both sides of the slope column, and a hollow movable block is slidably connected to the inner side of the hollow fixing block.

[0008] Preferably, a guide slide rod is fixedly connected to the inner side of the hollow fixing block, and the guide slide rod is set on the inner wall of the hollow fixing block near the slope column. Pull blocks are slidably connected to both sides of the guide slide rod, and compression springs are fixedly connected to the opposite side of the two pull blocks.

[0009] Preferably, a linkage pressure rod is rotatably connected to the inner side of the hollow movable block, and the linkage pressure rod is set on the inner wall of the hollow movable block on the side away from the slope column, and the other end of the linkage pressure rod is rotatably connected to the outer side of the tension block.

[0010] Preferably, the adjustment component includes a support block fixedly connected to the right side of the sliding block, the support block being slidably connected to the right side of the sliding rail, and a threaded sleeve being fixedly connected to the inner side of the sliding block.

[0011] Preferably, an adjusting screw is movably connected to the right side of the sliding rail, and the threaded sleeve is threadedly connected to the outside of the adjusting screw.

[0012] Preferably, a contact plate is fixedly connected to the outer side of the slope column.

[0013] Preferably, an extension block is fixedly connected to the outer side of the sliding rail, a telescopic column is fixedly connected to the top of the extension block, a buffer spring is fixedly connected to the outer side of the telescopic column, and the telescopic column is located at the bottom of the contact plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, by setting up a protective adjustment integrated mechanism, allows the fixed base to be elongated, with the slope column rotatably connected to one end of the fixed base. This is combined with a sliding rail and a threaded sliding block on the rear half of the fixed base. The distance between the sliding block and the column is adjusted using an adjusting screw. Combined with a self-resetting bidirectional telescopic damper with a rotating component between the sliding block and the slope column, a triangular-like stable structure is formed. This achieves fine-tuning of the slope column's angle towards the slope from 0-40 degrees to adapt to the slope, avoiding repeated adjustments and installations. Furthermore, the damper allows for slight rotation under impact, enhancing resilience and protective effect. This solves the problem of repeated adjustments and installations required due to the mismatch between the column angle and the slope under the original fixed connection.

[0016] 2. This application, by setting up an elastic connection mechanism, can replace the original rigid connection hanging ring by setting up a nested contraction structure composed of a hollow fixed block and a hollow movable block at the connection point between the protective net and the slope column. When the protective net is impacted, the hollow movable block is pulled, causing the linkage pressure rod to flip inward and the tension block to slide inward and press the pressure spring to form a buffer. This not only avoids the hanging ring from breaking but also ensures the stability of the connection, thus solving the problem that the hanging ring under the original rigid connection is prone to breakage when the protective net is impacted.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 The present invention provides the following technical solution:

[0024] A slope anti-slip device for highways includes a slope column 1. A protective adjustment integrated mechanism 2 is movably connected to the bottom of the slope column 1. An elastic connection mechanism 3 is movably connected to the outside of the slope column 1. A hanging ring 4 is fixedly connected to the outside of the elastic connection mechanism 3. A protective net 5 is hinged to the outside of the hanging ring 4. The protective adjustment integrated mechanism 2 includes a fixed base 21. The slope column 1 is rotatably connected to the top of the fixed base 21. A sliding rail 22 is fixedly connected to the rear side of the fixed base 21. A sliding block 23 is slidably connected to the inner side of the sliding rail 22. Rotating components 24 are fixedly connected to the opposite side of the sliding block 23 and the slope column 1. A self-resetting bidirectional telescopic damper 25 is rotatably connected to the inner side of the rotating component 24. The two ends of the self-resetting bidirectional telescopic damper 25 are rotatably connected to the inner sides of the two rotating components 24 respectively. An adjustment component 26 is movably connected to the outside of the sliding block 23.

[0025] In this embodiment: the slope support column 1 is not directly connected to the ground fixed base 21 at a fixed angle, but is rotatably connected to one end of the long strip fixed base 21. The rear half of the fixed base 21 has a sliding rail 22 and a sliding block 23 on the inner side. The distance between the sliding block 23 and the slope support column 1 can be adjusted by adjusting the component 26. The sliding block 23 and the rotating part 24 on the corresponding side of the slope support column 1 are connected to the two ends of the self-resetting bidirectional telescopic damper 25, forming a triangular structure to enhance stability. The slope support column 1 can also be finely adjusted from 0 to 40 degrees towards the slope side by adjusting the screw 2603 to adapt to the slope and avoid repeated installation and adjustment. The self-resetting bidirectional telescopic damper 25 allows small-amplitude rotation when subjected to large impacts, enhancing the resistance and protection effect.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the elastic connection mechanism 3 includes a hollow fixing block 31, which is fixedly connected to both sides of the slope column 1, and a hollow movable block 32 is slidably connected to the inner side of the hollow fixing block 31.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a guide slide rod 33 is fixedly connected to the inner side of the hollow fixing block 31, and the guide slide rod 33 is set on the inner wall of the hollow fixing block 31 near the slope column 1. Pull blocks 34 are slidably connected to both sides of the guide slide rod 33, and compression springs 35 are fixedly connected to the opposite side of the two pull blocks 34.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a linkage pressure rod 36 is rotatably connected to the inner side of the hollow movable block 32, and the linkage pressure rod 36 is set on the inner wall of the hollow movable block 32 away from the slope column 1. The other end of the linkage pressure rod 36 is rotatably connected to the outer side of the tension block 34.

[0029] In this embodiment: When the existing protective net 5 is hinged to the outer hanging ring 4 of the slope column 1, the hanging ring 4 is often rigidly connected to the outer wall of the slope column 1 and is prone to collapse. After improvement, a nested contraction structure composed of a hollow fixed block 31 and a hollow movable block 32 is set at the connection point. When impacted, the hanging ring 4 will pull the hollow movable block 32, causing the linkage pressure rod 36 to flip inward and the tension block 34 to slide inward along the guide slide rod 33 and press the compression spring 35, which is like a hand gripper to offset the impact, making the hanging ring 4 dynamically adjustable and elastically buffered, and preventing the protective net 5 from detaching and the hanging ring 4 from collapsing.

[0030] Specifically, such as Figure 3As shown, the adjustment component 26 includes a support block 2601 fixedly connected to the right side of the sliding block 23, the support block 2601 being slidably connected to the right side of the sliding rail 22, and a threaded sleeve 2602 being fixedly connected to the inner side of the sliding block 23.

[0031] Specifically, such as Figure 3 As shown, an adjusting screw 2603 is movably connected to the right side of the sliding rail 22, and a threaded sleeve 2602 is threadedly connected to the outside of the adjusting screw 2603.

[0032] In this embodiment: the rear half of the fixed base 21 has a sliding rail 22, the inner side of the sliding rail 22 has a sliding block 23, and the outer side of the sliding block 23 has a support block 2601 with a built-in threaded sleeve 2602. The distance between the sliding block 23 and the slope column 1 can be adjusted by adjusting the screw 2603.

[0033] Specifically, such as Figure 1 , Figure 2 As shown, a contact plate 6 is fixedly connected to the outer side of the slope column 1.

[0034] Specifically, such as Figure 2 As shown, an extension block 7 is fixedly connected to the outer side of the sliding rail 22, a telescopic column 8 is fixedly connected to the top of the extension block 7, a buffer spring 9 is fixedly connected to the outer side of the telescopic column 8, and the telescopic column 8 is located at the bottom of the contact plate 6.

[0035] In this embodiment: the external buffer spring 9 supported by the contact plate 6 made of elastic material on the outside of the slope column 1 and the extension block 7 on the outside of the sliding rail 22 can protect and support the rapid overturning impact of the contact plate 6 under special circumstances where the impact force is too large and the damper contracts uncontrollably, thus avoiding the overall collapse.

[0036] Working Principle: In high-risk sections of highway slopes, a section of anti-slope structure is typically constructed, consisting of two slope support columns 1 with their inclined sides facing the non-slope side and a resilient protective net 5. During installation, the fixed base 21 of the slope support column 1 is usually first firmly anchored to the ground before installation. However, because the slope support column 1 and the fixed base 21 are fixedly connected, repeated angle adjustments and reinstallation are often necessary to ensure that the slope of the slope support column 1 matches the slope gradient in its normal state. To avoid this, the slope support column 1 is no longer directly connected to the fixed base 21 at a fixed angle. Instead, the fixed base 21 is designed as a long strip, and the slope support column 1 is rotatably connected to one end of the fixed base 21. The rear half of the fixed base 21 is fixedly connected to a sliding rail 22, and a sliding block 23 is provided on the inner side of the sliding rail 22. A support block 2601 with an internal threaded sleeve 2602 is provided on the outside of the sliding block 23. The distance between the sliding block 23 and the slope column 1 can be adjusted by adjusting the screw 2603. Rotating components 24 are provided on the corresponding sides of the sliding block 23 and the slope column 1. Self-resetting bidirectional telescopic dampers 25 are rotatably connected to both ends of the rotating components 24, thus forming a triangular-like structure consisting of the fixed base 21 and the sliding rail 22, the slope column 1, and the rotating components 24 and the self-resetting bidirectional telescopic dampers 25, thereby enhancing stability. This method also allows for adjustment of the slope column 1 by adjusting the screw 2603 during installation. The angle of column 1 is finely adjusted, rotating it from 0 to 40 degrees towards the slope side, avoiding repeated installation and adjustments to meet the slope requirements. Furthermore, the self-resetting bidirectional telescopic damper 25 allows for slight rotation after a large impact, further enhancing the resistance and protective effect of the slope column 1 and the protective netting 5. Secondly, although the existing protective netting 5 possesses impact-resistant deformation capacity and toughness, it is usually installed by hinged connection to the outside of the slope column 1 via hanging rings 4. However, the hanging rings 4 of the slope column 1 are usually rigidly connected to the outer wall of the slope column 1. Therefore, when the protective netting 5 is impacted, the hanging rings 4 on the outside of the slope column 1 are highly likely to break. Therefore, instead of directly connecting the hanging rings 4 to the outside of the slope column 1, a perforated fixing block 3 is installed at the connection point. The nested contraction structure formed by the 1 and the hollow movable block 32 allows the protective netting 5 to be impacted. When the protective netting 5 is impacted, the outer hanging ring 4 of the slope column 1 pulls the hollow movable block 32 towards the outside of the hollow fixed block 31. At the same time, the two sets of linkage pressure rods 36 on the inner wall of the hollow movable block 32 will flip inward, reducing the angle between the two linkage pressure rods 36. Consequently, the tension block 34, which is rotatably connected to its bottom and limited by the guide slide rod 33, will slide inward simultaneously and press the compression spring 35 between the two tension blocks 34, thus achieving a gripper-like effect to offset and protect against the impact force. This ensures that the hanging ring 4 is in a dynamically adjustable and elastically buffered state, preventing the protective netting 5 from detaching from the hanging ring 4 and collapsing. Additionally, an elastic contact plate 6 is provided on the outer side of the slope column 1.A telescopic column 8, supported by an external buffer spring 9 and extended by an extension block 7, is installed on the outside of the sliding rail 22. This telescopic column 8 provides protection in special circumstances. When the impact force is too large and the damper contracts uncontrollably, the telescopic column 8 protects and supports the contact plate 6 from rapid overturning impact, preventing overall collapse. In summary, this optimizes the anti-slip device for highway slopes.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
