Description

Technical Field

[0001] This invention relates to the field of highway protection technology, and in particular to a slope rockfall protection device for mountain highways. Background Technology

[0002] Mountainous areas have complex geological structures and intricate rock layers. Some rocks may have become loosely structured due to long-term crustal movement, weathering, and water erosion, making them prone to collapse and landslides, thus triggering rockfalls. Climate change, rainfall, and temperature variations cause rocks to expand and contract, accelerating rock decomposition and weathering, thereby increasing the likelihood of rockfalls. Heavy rainfall can also cause soil erosion, further weakening slope stability and contributing to rockfall events.

[0003] Rockfalls on mountain highway slopes are typically intermittent events. This means that rockfalls are not continuous but occur at regular intervals. This intermittency can be influenced by various factors, such as geological conditions, climate change, and human activities. The intermittency of rockfalls also increases the challenges of prevention and management, as they can occur at any time and can have a sudden and adverse impact on traffic safety and road infrastructure. Specifically:

[0004] Rockfalls can suddenly roll onto highways, causing traffic accidents and threatening the lives and property of drivers. Rockfalls can also impact road surfaces, damaging road infrastructure and requiring frequent repairs, increasing maintenance costs. Furthermore, rockfalls can block highways, causing traffic disruptions and affecting the passage of local and passing vehicles.

[0005] In existing technologies, slope design and reinforcement are commonly used, employing protective measures such as slope protection nets and retaining walls to enhance slope stability. However, through long-term work and research, the inventors have discovered the following technical problems in this traditional technology that urgently need to be addressed:

[0006] (1) Limited adaptability: Traditional slope protection nets, retaining walls and other technologies are usually static structures, which are difficult to flexibly cope with slopes of different shapes and sizes as well as falling rocks at different angles, and may not be able to provide ideal protection under various complex terrain conditions.

[0007] (2) Limited protective effect: Traditional technologies may have limited protective effect when faced with large-scale, high-speed rockfalls. Especially when faced with strong impact, the slope protection net may be damaged and the retaining wall may collapse, failing to provide effective protection continuously.

[0008] (3) High maintenance and repair costs: Traditional technologies have complex structures, and once damaged, they require a lot of time and resources for repair and maintenance. Moreover, due to the complex mountain environment, maintenance difficulties may lead to the failure of protective devices during use, affecting the safety of the highway.

[0009] (4) Insufficient adjustability: Traditional technology is difficult to adjust the angle and position in real time and lacks precise control over the protective device, which may not be able to flexibly adapt to changes in the slope rockfall situation.

[0010] (5) High construction difficulty: The construction process of traditional technology may be more complicated, involving a large amount of manpower and material resources, and requires a long construction period, which may affect the normal use of the highway.

[0011] Therefore, a slope protection device for mountain roads is proposed. Summary of the Invention

[0019] In one embodiment, the support mechanism further includes at least two telescopic shafts, the cylinders of which are fixed to the frame, and the piston rods of all the telescopic shafts are hinged to the upper or lower part of the outermost protective plate.

[0020] In the above-described embodiment, in addition to the frame and the first hydraulic cylinder mentioned earlier, the support mechanism also incorporates at least two telescopic shafts. The cylinder bodies of the telescopic shafts are fixed to the frame, while the piston rods of all telescopic shafts are hinged to the upper or lower part of the outermost protective plate.

[0021] In one embodiment: the supporting mechanism includes a triangular support frame, the top of which is hinged to a sleeve, and a telescopic arm for outputting the third linear degree of freedom is slidably fitted inside the sleeve along the Z-axis or X-axis; one end of the telescopic arm is fixedly connected to the frame of the support mechanism; it also includes a second hydraulic cylinder for outputting the second linear degree of freedom, the cylinder body and piston rod of the second hydraulic cylinder being respectively hinged to the middle of the triangular support frame and the middle of the sleeve.

[0022] In the above embodiment: the supporting mechanism consists of a triangular support frame, the top of which is hinged to a sleeve. The sleeve slides along the Z-axis or X-axis and is fitted with a telescopic arm for outputting the third linear degree of freedom. One end of the telescopic arm is fixedly connected to the frame of the support mechanism. Furthermore, this embodiment also includes a second hydraulic cylinder for outputting the second linear degree of freedom. The cylinder body and piston rod of the second hydraulic cylinder are respectively hinged to the middle of the triangular support frame and the middle of the sleeve.

[0023] In one embodiment, the outer surfaces of the sleeve and the telescopic arm are provided with corresponding screw holes in a rectangular array, and the sleeve and the telescopic arm are detachably connected by bolts.

[0024] In the above implementation: a shock-absorbing spring is fitted on the sliding surface between the sleeve and the telescopic arm to reduce external impacts and vibrations.

[0025] In one embodiment, the device further includes a transport mechanism, which is installed on the bottom outer edge of the triangular support frame of the abutment mechanism. The transport mechanism is used to transport the slope rockfall protection equipment for mountain roads and abut against the ground to lock the position of the slope rockfall protection equipment for mountain roads.

[0026] In the above implementation method, in addition to the previously mentioned abutment mechanism and related components, a transport mechanism is also introduced. The main function of the transport mechanism is to carry and transport the slope protection equipment for mountain roads, and at the same time, by abutting against the ground, lock the position of the protection equipment.

[0027] In one embodiment: the transport mechanism includes a flatbed frame, the bottom of which is equipped with a plurality of lockable casters, and the flatbed frame is fixedly connected to the bottom outer edge of the triangular support frame; at least four ground-holding components for ground-holding are symmetrically installed on the outer surface of the flatbed frame.

[0028] In the above embodiment: the transport mechanism consists of a flatbed frame, the bottom of which is equipped with multiple lockable casters. These casters give the transport mechanism the ability to move flexibly on a flat surface. The flatbed frame is fixedly connected to the bottom outer edge of the triangular support frame.

In use, after the deployment, position, and angle of the support mechanism are completed, the ground-holding arm is tightly pressed against the ground by the third hydraulic cylinder, and then the expansion bolt is driven in.

[0030] In the above implementation method, by introducing ground-holding components, this method provides the transport mechanism with more robust ground support, making it more stable and reliable when transporting and positioning protective equipment. The use of ground-holding components enhances the stability of the entire protective device, enabling it to remain firmly fixed to the ground when facing external impacts and pressures, providing a higher level of protection for rockfall protection on mountain roads.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] I. Flexibility and Adaptability: The technology of this invention, through the design of the support mechanism, the jacking mechanism, and the transport mechanism, can flexibly deploy and adjust the position, angle, and shape of the protective plate according to actual conditions. This allows the protective device to adapt to slopes of different shapes and various rockfall angles, improving its overall adaptability.

[0033] II. Highly Effective Protection: Through the structure and deployment method of the protective plate, as well as the synergistic action of the support and abutment mechanisms, the technology of this invention can effectively resist and mitigate the impact of falling rocks. This design provides stronger and more durable protection, ensuring the safety of roads and vehicles. The M-shaped deployment method allows the impact force to be distributed more evenly across each fold layer, thereby reducing the risk of damage caused by excessive local stress. This helps extend the service life of the protective plate and reduce maintenance costs. The M-shaped deployment method ensures that the side with the sharp angle faces the side of the mountain slope where rocks are likely to fall, which allows for better interception and blocking of falling rocks. When a rock hits the M-shaped protective plate, its sharp angle can quickly guide the rock towards the surface of the protective plate, thereby effectively mitigating and dispersing the impact force and reducing the impact of falling rocks on the device.

[0034] III. Precise Adjustment and Control: The multi-degree-of-freedom adjustment of the jacking mechanism and the mobility of the transport mechanism allow for precise position and angle adjustments of the protective device. This precise control capability helps to better adapt to different situations and provide optimized protective effects.

[0035] Fourth, reduced maintenance costs: The design of the impact-resistant mechanism allows the protective plate to bend and twist upon impact, reducing damage to the overall structure and thus lowering maintenance costs. Furthermore, the adjustable design extends the service life of each component.

[0036] V. Convenient Construction and Maintenance: The introduction of the transport mechanism makes the transportation and positioning of the protective device more convenient, while the use of ground-mounted components simplifies the fixing and support of the device. This helps to shorten the construction cycle and improve construction efficiency.

[0037] VI. Enhanced Safety: The robust design of the protective plate, along with the supporting and abutment mechanisms, improves the stability and safety of the entire protective device. This design effectively prevents potential threats to roads and vehicles from falling rocks. Attached Figure Description

[0050] In existing technologies, traditional slope protection nets and retaining walls are commonly used methods for rockfall protection on mountain highway slopes, and they have been widely applied in the past. Slope protection nets are mesh structures made of metal wire or synthetic fiber materials, fixed to the slope surface to prevent rocks from rolling onto the road. Slope protection nets can intercept smaller rocks, reducing the impact of rockfalls on traffic and the surrounding environment. Their construction is relatively simple and suitable for some smaller-scale rockfall risk areas. However, the protective capacity of slope protection nets is limited; larger and high-speed rocks may penetrate the mesh, creating safety hazards for road traffic. Furthermore, slope protection nets may break upon impact, requiring regular maintenance and replacement. Retaining walls are a common structure used to stabilize slopes and protect roads, typically constructed from materials such as concrete and brick. Retaining walls form a vertical or near-vertical structure on the slope, effectively stabilizing the slope and preventing rockfalls. They can prevent larger rocks from rolling down, providing strong protection. However, retaining walls have higher construction and maintenance costs, requiring longer construction periods and significant resources. Furthermore, retaining walls may collapse under impact, severely impacting road traffic. For this information, please refer to [link / reference needed]. Figure 1-5 This specific embodiment will provide a relevant technical solution to solve the above-mentioned technical problems: a slope rockfall protection device for mountain highways, including a support mechanism 1; the support mechanism 1 includes a protective plate 101, and at least one first linear degree of freedom; at least four protective plates 101 are hinged to each other and folded together; the first linear degree of freedom simultaneously unfolds all the protective plates 101 in an M-shape or a straight line, wherein in the M-shape, the side with the acute angle faces the side of the mountain slope rockfall, and the formation of the M-shape means that its four lines correspond to at least four protective plates 101; the support mechanism 1 is equipped with a jacking mechanism 2, the jacking mechanism 2 includes a second linear degree of freedom and a third linear degree of freedom, the second linear degree of freedom and the third linear degree of freedom are respectively used to adjust the tilt angle and feed distance of the support mechanism 1; the jacking mechanism 2 is set on the ground and supports the support mechanism 1.

[0051] In this scheme: After determining the position of the jacking mechanism 2, the support mechanism 1 unfolds multiple protective plates 101 from their folded state. Two modes are available: one is an M-shaped unfolding, and the other is a straight-line unfolding. The unfolded protective plates 101 are then used for rockfall protection on mountain highways.

[0052] In this scheme: the slope rockfall protection equipment for mountain roads includes a support mechanism 1 and a jacking mechanism 2. The support mechanism 1 consists of protective plates 101 and at least one first linear degree of freedom. The protective plates 101 are hinged together and can be folded together. The first linear degree of freedom is used to deploy all the protective plates 101 in an M-shape or a straight line, wherein when deployed in an M-shape, the acute angle side faces one side of the mountain slope. The jacking mechanism 2 includes a second linear degree of freedom and a third linear degree of freedom, used to adjust the tilt angle and feed distance of the support mechanism 1. The jacking mechanism 2 is located on the ground and supports the support mechanism 1.

[0053] Specifically, the core principle of this protective equipment is to effectively prevent slope rockfalls from threatening mountain roads through the coordinated action of the support mechanism 1 and the jacking mechanism 2, as well as the deployment state of the protective plate 101. The protective plate 101 of the support mechanism 1 can be deployed when needed, forming an M-shape or a straight line to cover potential rockfall areas and prevent rocks from rolling down. Simultaneously, through the adjustment of the jacking mechanism 2, the support mechanism 1 can operate at different inclination angles and feed distances, adapting to different slope morphologies and rockfall risks.

[0054] In this design, the M-shaped deployment of the protective plate 101 has the following beneficial effects:

[0055] (1) The M-shaped deployment method allows the side with the acute angle to face the side of the mountain slope where rocks are falling. This design can better intercept and block falling rocks. When a rock hits the M-shaped protective plate 101, its acute angle can quickly guide the rock to the surface of the protective plate 101, thereby effectively slowing down and dispersing the impact force and reducing the impact of falling rocks on the device.

[0056] (2) The M-shaped unfolded protective plate 101 forms multiple folded layers in shape, which can provide multiple layers of protection against falling rocks, greatly increasing the ability to intercept and disperse the impact of falling rocks. This multi-layered protection can effectively reduce the impact of falling rocks on the device.

[0057] (3) The M-shaped design allows the various parts of the protective plate 101 to adapt to the size and shape of falling rocks. Smaller rocks are intercepted by the forward folding layers, while larger rocks are intercepted and dispersed by deeper layers. This adaptability helps to improve the protective effect.

[0058] (4) The M-shaped unfolding method allows the impact force to be distributed more evenly across each fold, thereby reducing the risk of damage caused by excessive local stress. This helps to extend the service life of the protective plate 101 and reduce maintenance costs.

[0059] Therefore, the M-type protection system, with its advantages of multi-layered protection, adaptability, and balanced distribution of impact force, can play an important role in rockfall protection on mountain highway slopes, improving the effectiveness and stability of the protection device.

[0060] In this design, the linear deployment of the protective plate 101 has the following advantages:

[0061] (1) Full coverage of the slope area: The straight-line deployment can cover the slope over a wide range, and the protective plates 101 are arranged in a straight line to ensure that the entire slope area is effectively protected, thereby reducing the risk of rockfall impact.

[0062] (2) Adapting to wider slopes: For wider slopes, the straight-line deployment can better adapt and ensure that the protective plate 101 is fully covered, avoiding the omission of protected areas due to the width of the slope.

[0063] (3) Simplified construction and maintenance: In the linear deployment mode, the protective plates 101 are arranged in a straight line, which simplifies construction and maintenance, makes it easier to position and adjust, and reduces the complexity of operation and labor costs.

[0064] It is understood that this specific implementation method can flexibly adjust and switch between linear and M-shaped modes, and has the following beneficial effects:

[0065] (1) To cope with different situations: Under different slope shapes and rockfall angles, the straight or M-shaped deployment method can be flexibly selected to ensure that the protective plate 101 can play a protective role to the greatest extent under different situations.

[0066] (2) Optimize protection effect: Select the most suitable deployment mode according to the specific rockfall situation. This can optimize the dispersion and absorption of impact force, improve the protection effect, and reduce the risk of damage to the device.

[0067] (3) To cope with rocks of different sizes: The structure and position of the protective plate 101 change under different deployment modes, which can better cope with falling rocks of different sizes and speeds, and enhance adaptability and protection capabilities.

[0068] It is understood that, in this specific embodiment, this protective equipment has significant functionalities at the application level. First, by unfolding the protective plate 101, a large area of ​​falling rocks can be covered, effectively reducing the impact of falling rocks on the highway. Second, the adjustable tilt angle and feed distance of the support mechanism 1 allow the equipment to adapt to different slope conditions and falling rock threats, improving the flexibility and applicability of the protective effect. Finally, the supporting role of the jacking mechanism 2 ensures the stability and reliability of the support mechanism 1, thereby guaranteeing the long-term effective operation of the protective equipment. This slope rockfall protection equipment for mountain highways, through its innovative design and structure, provides an efficient and reliable protection solution for mountain highways, significantly reducing traffic safety hazards and facility damage risks caused by slope rockfalls.

[0069] Please refer to the following specific embodiments in this application. Figures 3-5 The support mechanism 1 includes a frame 102, which is equipped with a first hydraulic cylinder 105 for outputting the first linear degree of freedom. The first hydraulic cylinder 105 is used to drive all the protective plates 101 to unfold in an M-shape or a straight line. The abutment mechanism 2 is connected to the frame 102 of the support mechanism 1.

[0070] In this scheme: the support mechanism 1 includes a frame 102, on which a first hydraulic cylinder 105 is mounted for outputting a first linear degree of freedom. The function of the first hydraulic cylinder 105 is to drive all the protective plates 101, causing them to unfold in an M-shape or a straight line. The jacking mechanism 2 is connected to the frame 102 of the support mechanism 1, and this connection provides the necessary support and stability for the coordinated operation of the support mechanism 1 and the jacking mechanism 2.

[0071] Specifically: The frame 102 of the support mechanism 1 serves to support and drive the protective plate 101. The first hydraulic cylinder 105 acts as a power source, hydraulically driving the protective plate 101 to unfold in an M-shape or a straight line, thereby covering potential rockfall areas. The supporting mechanism 2 is connected to the frame 102 of the support mechanism 1, designed to stably support the support mechanism 1 and ensure its stability and balance during the unfolding of the protective plate 101.

[0072] It is understood that in this specific embodiment: This embodiment further emphasizes the structure and driving method of the support mechanism 1, making it more controllable and adaptable when the protective plate 101 is deployed. The use of the first hydraulic cylinder 105, through hydraulic force, can effectively realize the deployment of the protective plate 101, thereby achieving the shielding of falling rocks. The connection of the abutment mechanism 2 ensures the stability of the support mechanism 1, so that the entire protective device can always remain robust and reliable during operation, thereby providing long-lasting slope rockfall protection for highways. This embodiment further improves the protective device in terms of structure and mechanism. Through the precise control of the hydraulic system and the synergistic effect of the abutment mechanism 2, the effective deployment and stable operation of the protective plate 101 are achieved, thereby enhancing the reliability and practicality of the entire protective equipment.

[0073] Please refer to the following specific embodiments in this application. Figures 3-5 The support mechanism 1 also includes an X-shaped hinge 104, wherein the X-shaped hinge 104 is formed by several plates that are hinged to each other with their respective centerlines as hinge points to form an X shape, and each of the four ends of the multiple X-shaped components is respectively hinged to another X-shaped component. The end of the X-shaped hinge 104 furthest from the frame 102 is hinged to the middle of the outermost protective plate 101; the cylinder body and piston rod of the first hydraulic cylinder 105 are respectively hinged to the outer surfaces of the frame 102 and the X-shaped hinge 104.

[0074] In this scheme: When in use, the first hydraulic cylinder 105 outputs the first linear degree of freedom, pushing the X-shaped hinge 104. The outermost X-shaped hinge 104 drives the outermost protective plate 101 to unfold. The protective plate 101 relies on the hinge connection characteristics to pull the other protective plates 101 to unfold in an M-shape or a straight line.

[0075] In this scheme: In addition to the previously mentioned frame 102 and first hydraulic cylinder 105, the support mechanism 1 also incorporates an X-shaped hinge 104. The X-shaped hinge 104 is formed by several plates with their respective centerlines as hinge points, creating an X-shaped structure. Furthermore, each of the four ends of multiple X-shaped components is hinged to another X-shaped component. The farthest end of the X-shaped hinge 104 is hinged to the frame 102, and the middle of the outermost protective plate 101 is hinged to the other end of the X-shaped hinge 104.

[0076] Specifically, the core principle is to more precisely control the unfolding process of the protective plate 101 through the design of the X-shaped hinge 104. When the first hydraulic cylinder 105 outputs the first linear degree of freedom, it pushes the X-shaped hinge 104, and the movement of the outermost X-shaped hinge 104 will drive the outermost protective plate 101 to unfold. Due to the hinged characteristics, the unfolding of the outermost protective plate 101 will affect the other protective plates 101, causing them to unfold in an M-shape or a straight line, thereby forming effective protection against falling rocks.

[0077] It is understandable that in this specific embodiment, the functionality of the implementation emphasizes control over the deployment process of the protective plate 101. The introduction of the X-shaped hinge 104 makes the deployment of the protective plate 101 more orderly and stable, ensuring that no uncontrolled or uneven deployment occurs. The movement of the X-shaped hinge 104 can be precisely controlled through the output of the first hydraulic cylinder 105, thereby realizing the deployment of the protective plate 101. This precise control method enhances the overall protective effect of the protective device and improves the safety of highways facing slope rockfalls. The ingenious design of the X-shaped hinge 104 achieves the orderly deployment of the protective plate 101, making the protective device more reliable and precise. At the same time, this structure also increases the stability and durability of the protective device, providing stronger slope rockfall protection for mountain highways.

[0078] Please refer to the following specific embodiments in this application. Figures 3-5 The support mechanism 1 also includes at least two telescopic shafts 103, the cylinders of which are fixed to the frame 102, and the piston rods of all the telescopic shafts 103 are hinged to the upper or lower part of the outermost protective plate 101.

[0079] In this design: in addition to the previously mentioned frame 102 and first hydraulic cylinder 105, the support mechanism 1 also incorporates at least two telescopic shafts 103. The cylinder bodies of the telescopic shafts 103 are fixed to the frame 102, while the piston rods of all the telescopic shafts 103 are hinged to the upper or lower part of the outermost protective plate 101.

[0080] Specifically, the core principle is to apply additional reinforcement and support to the upper and lower parts of the protective plate 101 through the introduction of the telescopic shaft 103. During the unfolding of the protective plate 101, the telescopic shaft 103 extends synchronously, and their piston rods apply force to the upper or lower part of the protective plate 101, further enhancing the structural stability of the protective plate 101 and effectively distributing the external impacts and pressures on the protective plate 101.

[0081] It is understood that in this specific embodiment, the introduction of the telescopic shaft 103 is designed to improve the protective device's resistance to falling rocks. By extending the telescopic shaft 103, additional support can be provided to the upper and lower parts of the protective plate 101 during its deployment, thereby reducing possible bending or deformation and enhancing the stability of the entire protective device. This design not only helps prevent rockfall penetration but also contributes to the long-term durability and service life of the protective plate 101. By introducing the telescopic shaft 103, this embodiment further strengthens the structure of the protective device, increases support for the upper and lower parts of the protective plate 101, and improves the stability and reliability of the entire device. This reinforced design makes the protective device perform better when facing strong impacts and pressures, providing greater protection for rockfall protection on mountain roads.

[0082] Please refer to the following specific embodiments in this application. Figures 3-5 The supporting mechanism 2 includes a triangular support frame 201, with a sleeve 202 hinged to the top of the triangular support frame 201. A telescopic arm 203 for outputting the third linear degree of freedom is slidably fitted inside the sleeve 202 along the Z-axis or X-axis. One end of the telescopic arm 203 is fixedly connected to the frame 102 of the support mechanism 1. It also includes a second hydraulic cylinder 204 for outputting the second linear degree of freedom. The cylinder body and piston rod of the second hydraulic cylinder 204 are respectively hinged to the middle of the triangular support frame 201 and the middle of the sleeve 202.

[0083] In this scheme: during use, based on the second linear degree of freedom output by the second hydraulic cylinder 204, the pitch angle of the sleeve 202 and the telescopic arm 203 is adjusted so that the support mechanism 1 faces the side of the mountain road slope with a suitable angle; then, the sliding distance between the telescopic arm 203 and the sleeve 202 is adjusted to control the support mechanism 1 to face the side of the mountain road slope with a suitable distance.

[0084] In this embodiment: the supporting mechanism 2 consists of a triangular support frame 201, the top of which is hinged to a sleeve 202. The sleeve 202 slides along the Z-axis or X-axis and is fitted with a telescopic arm 203 for outputting the third linear degree of freedom. One end of the telescopic arm 203 is fixedly connected to the frame 102 of the support mechanism 1. Furthermore, this embodiment also includes a second hydraulic cylinder 204 for outputting the second linear degree of freedom. The cylinder body and piston rod of the second hydraulic cylinder 204 are respectively hinged to the middle of the triangular support frame 201 and the middle of the sleeve 202.

[0085] Specifically, the core principle is that the design of the support mechanism 2 allows the support mechanism 1 to face the side of the mountain road slope prone to rockfall at a suitable angle and spacing, achieving effective protection against the falling rocks. Through the output of the second hydraulic cylinder 204, the pitch angle of the sleeve 202 and the telescopic arm 203 is adjusted, ensuring the support mechanism 1 faces the appropriate direction. Subsequently, by adjusting the sliding distance between the telescopic arm 203 and the sleeve 202, the support mechanism 1 is controlled to face the falling rocks at an appropriate distance and angle, achieving precise protective positioning.

[0086] It is understood that in this specific embodiment, the emphasis is on the precise control of the angle and position of the support mechanism 1 by the abutment mechanism 2 in terms of functionality. Through the action of the second hydraulic cylinder 204, the orientation of the support mechanism 1 can be adjusted to face the side of the slope prone to rockfall on mountain roads. The sliding adjustment of the telescopic arm 203 can further control the distance between the support mechanism 1 and the falling rocks, ensuring that the protective plate 101 can be deployed in the most suitable position to achieve the best protective effect. This design has significant advantages in terms of the precision and adaptability of the protective device. By introducing the combination of the triangular support frame 201, the telescopic arm 203, and the hydraulic system, this embodiment further improves the operational flexibility and protective effect of the abutment mechanism 2. Through precise control, the support mechanism 1 can be adjusted in angle and position according to the actual situation, providing a higher level of safety guarantee for the protection of slopes prone to rockfall on mountain roads.

[0087] Please refer to the following specific embodiments in this application. Figures 3-5 The outer surfaces of both the sleeve 202 and the telescopic arm 203 are provided with corresponding screw holes in a rectangular array, and the sleeve 202 and the telescopic arm 203 are detachably connected by bolts.

[0088] In this scheme: after adjusting the sliding distance between the telescopic boom 203 and the sleeve 202, and controlling the support mechanism 1 to face the side of the mountain road slope prone to rockfall at a suitable distance, the screw holes that fit the sleeve 202 and the telescopic boom 203 in the current state are found. Then, multiple bolts are installed in a hole-to-hole manner to eliminate the second linear degree of freedom between the sleeve 202 and the telescopic boom 203, that is, to eliminate the sliding fit relationship and increase the protection strength. When a rockfall hits the protective plate 101, the shock-absorbing spring can further eliminate the force.

[0089] In this design, a shock-absorbing spring is fitted on the sliding surface between the sleeve 202 and the telescopic arm 203 to reduce external impacts and vibrations.

[0090] Specifically, the core principle of this implementation is to eliminate the sliding fit between the sleeve 202 and the telescopic arm 203 and improve the protective strength through the synergistic effect of the screw holes, bolts, and shock-absorbing springs. After adjusting the sliding distance between the telescopic arm 203 and the sleeve 202 to adapt the support mechanism 1 to the specific situation of rockfall on mountain roads, the screw holes of the sleeve 202 and the telescopic arm 203 are aligned and connected by installing bolts, eliminating the sliding fit and thus increasing the protective strength.

[0091] It is understood that in this specific embodiment, the functionality of the support mechanism 1 is emphasized by enhancing its adaptability and protective effect. The design of the screw holes and bolts allows the sleeve 202 and the telescopic arm 203 to be fixed in a fixed position within a specific sliding distance, thereby increasing the stability and reliability of the support mechanism 1. Simultaneously, the presence of the shock-absorbing springs mitigates external impacts, further protecting the protective plate 101 from strong vibrations and impacts, thus extending the service life of the protective device. This embodiment, through the combined application of screw holes, bolts, and shock-absorbing springs, strengthens the stability and resistance of the support mechanism 1. The bolt fixing ensures the protective device remains stable under specific conditions, while the shock-absorbing springs provide additional protection, enabling the protective plate 101 to better withstand external forces when facing rolling stone impacts, improving the protective effect and the durability of the device.

[0092] Please refer to the following specific embodiments in this application. Figures 3-5 The device also includes a transport mechanism 3, which is installed on the bottom outer edge of the triangular support frame 201 of the abutment mechanism 2. The transport mechanism 3 is used to transport the slope rockfall protection equipment for mountain roads and abut against the ground to lock the position of the slope rockfall protection equipment for mountain roads.

[0093] In this solution, in addition to the previously mentioned abutment mechanism 2 and related components, a transport mechanism 3 is also introduced. The main function of the transport mechanism 3 is to carry and transport the slope protection equipment for mountain roads, and at the same time, by abutting against the ground, it locks the position of the protection equipment.

[0094] Specifically, the core principle is to ensure the stability and reliability of the protective device through the installation and transportation functions of the transport mechanism 3. The transport mechanism 3 lifts and transports the protective equipment from under the supporting mechanism 2, and then pushes it against the ground, thereby fixing the position of the protective equipment. In this way, when the protective device is deployed and in operation, its position will be effectively locked and will not move or loosen due to external factors.

[0095] It is understood that in this specific embodiment, the transport mechanism 3 emphasizes the installation and stabilization of the protective device in terms of functionality. Through the transport mechanism 3, the protective equipment can be accurately lifted and positioned to the required location, and then locked in place by pressing against the ground, ensuring that its position does not change during operation. This design increases the stability of the entire protective device, enabling it to remain robust and reliable when facing rockfall impacts. By introducing the transport mechanism 3, this embodiment further enhances the reliability and ease of operation of the entire protective device. The function of the transport mechanism 3 makes the installation and locking of the protective equipment simpler and more precise, providing a higher level of protection for rockfall protection on mountain roads.

[0096] Please refer to the following specific embodiments in this application. Figures 3-5 The transport mechanism 3 includes a flatbed frame 301, which has multiple lockable casters installed at the bottom of the frame. The flatbed frame 301 is fixedly connected to the bottom outer edge of the triangular support frame 201. At least four ground-holding components for ground-holding are symmetrically installed on the outer surface of the flatbed frame 301.

[0097] In this design: the transport mechanism 3 consists of a flatbed frame 301, the bottom of which is equipped with multiple lockable casters. These casters enable the transport mechanism 3 to move flexibly on a stable surface. The flatbed frame 301 is fixedly connected to the bottom outer edge of the triangular support frame 201. Furthermore, at least four ground-holding components are symmetrically mounted on the outer surface of the flatbed frame 301 for securely supporting it against the ground.

[0098] Specifically, the core principle is to accurately transport and position the protective equipment through the pallet frame 301 and the transport mechanism 3 on it. The casters on the pallet frame 301 allow the transport mechanism 3 to move flexibly on a stable surface, facilitating the transport of the protective equipment to the required location. By fixing the pallet frame 301 to the bottom outer edge of the triangular support frame 201, a stable connection is achieved between the transport mechanism 3 and the ground-holding mechanism 2. The design of the ground-holding component ensures that the pallet frame 301 firmly rests against the ground, increasing the stability of the entire device.

[0099] Understandably, in this specific embodiment, the transport mechanism 3 can easily move on the ground via the casters on the pallet frame 301, thus achieving precise transport of the protective equipment. Connecting the pallet frame 301 to the triangular support frame 201 ensures the stability of the transport mechanism 3 during transport and positioning. The presence of the ground-holding component further increases the contact area between the transport mechanism 3 and the ground, improving the stability and support capacity of the entire protective device. By introducing the pallet frame 301 and its corresponding design, this embodiment increases the mobility and stability of the transport mechanism 3, making it more convenient and reliable for transporting and positioning protective equipment. Integrating these elements, the device can provide more efficient and precise protection against rockfalls on mountain roads.

[0100] Please refer to the following specific embodiments in this application. Figures 3-5 The ground-supporting component includes a third hydraulic cylinder 302 and a ground-supporting arm 303. One end of the ground-supporting arm 303 is hinged to the flatbed frame 301, and the other end rests against the ground. The cylinder body and piston rod of the third hydraulic cylinder 302 are respectively hinged to the middle of the flatbed frame 301 and the ground-supporting arm 303. A through groove for mates with expansion bolts is provided on the ground-facing end of the ground-supporting arm 303. The expansion bolts mate with the ground-supporting arm 303 and are inserted into the ground. In use, after the deployment, position, and angle of the support mechanism 1 are completed, the ground-supporting arm 303 is tightly pressed against the ground by the third hydraulic cylinder 302, and then the expansion bolts are driven in.

[0101] In this solution, by introducing ground-holding components, this implementation provides the transport mechanism 3 with more robust ground support, making it more stable and reliable when transporting and positioning protective equipment. The use of ground-holding components enhances the stability of the entire protective device, enabling it to remain firmly fixed to the ground when facing external impacts and pressures, providing a higher level of protection for rockfall protection on mountain roads.

[0102] Specifically: The design of the ground-supporting component further enhances the stability and ground support function of the transport mechanism 3. The output of the third hydraulic cylinder 302 controls the contact between the ground-supporting arm 303 and the ground, achieving a secure anchoring effect. The use of expansion bolts further strengthens the connection between the ground-supporting arm 303 and the ground, ensuring stability during the operation of the protective device.

[0103] Understandably, in this specific embodiment, the ground-holding arm 303 is tightly pressed against the ground by the action of the third hydraulic cylinder 302, thereby increasing the contact area and stability between the transport mechanism 3 and the ground. The insertion of the expansion bolts further strengthens the connection between the ground-holding arm 303 and the ground, ensuring the robustness of the entire device. This design has significant advantages in terms of the stability and reliability of the protective device.
