Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of road engineering, and in particular to a falling rock protection device for mountain roads. Background Art

[0002] Road engineering refers to the whole process of planning, designing, constructing, maintaining and managing work taking roads as objects and the engineering entities engaged in. Like any other category of civil engineering, road engineering has obvious characteristics in terms of technology, economy and management.

[0003] However, there is a existing falling rock protection device for mountain roads. The angles of protection and support required in different positions and environments are different, so adjustment is needed to achieve the best stability. When falling rocks act directly on the protection, the impact points will be too concentrated, reducing the protection effect. Utility Model Content

[0004] In view of the above problems, the embodiments of the present application provide a falling rock protection device for mountain roads to solve the problems of a existing falling rock protection device for mountain roads, where the angles of protection and support required in different positions and environments are different, so adjustment is needed to achieve the best stability. When falling rocks act directly on the protection, the impact points will be too concentrated, reducing the protection effect, etc.

[0005] The embodiments of the present application provide a falling rock protection device for mountain roads. It includes: a first protection plate, a cross plate is fixedly embedded and connected to one side of the first protection plate, a first support rod is hingedly installed on one side of the cross plate, a threaded rod is threadedly connected to the bottom end of the first support rod, a first bevel gear is fixedly installed on the outer wall of the threaded rod, a second bevel gear is meshed and connected to the surface of the first bevel gear, a rotating rod is fixedly installed on one side of the second bevel gear, the rotating rod is movably sleeved on one side of the second support rod, the threaded rod is movably sleeved inside the limiting groove, and the bottom of the first support rod is movably sleeved inside the limiting groove.

[0006] Through the above solution, by turning the rotating rod, the second bevel gear is driven to rotate, and the first bevel gear is driven to rotate through the meshing of the second bevel gear. Then, the threaded rod is driven to rotate inside the second support rod, so that the first support rod moves in a threaded manner on the surface of the threaded rod and slides upward from inside the second support rod to adjust the overall length, thereby adjusting the angle with the cross plate to increase the stability of the first protection plate and the second protection plate.

[0007] In some embodiments, first sliding grooves are symmetrically opened inside the limiting groove, first sliders are movably sleeved inside the first sliding grooves, and the first sliders are fixedly installed on the outer wall of the first support rod.

[0008] Through the above solution, when the first support rod is turned and moves upward inside the second support rod, the first slider slides in the first chute. The first slider and the first chute provide stability for the sliding of the first support rod, and at the same time, the first slider and the first chute also limit the sliding distance.

[0009] In some embodiments, a support base is fixedly installed at the bottom end of the second support rod, and a ground nail is fixedly embedded at the top end of the support base.

[0010] Through the above solution, after the first support rod and the second support rod are used for support, the support base is movably embedded into the soil, and then the ground nail is movably embedded into the soil. The contact area at the bottom end of the second support rod is increased through the support base and the ground nail to provide stability for the support.

[0011] In some embodiments, clamping grooves are symmetrically formed on both sides of the first protection plate, and limit blocks are movably sleeved inside the clamping grooves. The limit blocks are fixedly installed on one side of the second protection plate.

[0012] Through the above solution, the limit blocks are movably embedded into the clamping grooves, so that the second protection plate is movably embedded into one side of the first protection plate, playing a good role in embedded connection. The butt joint installation is made more fitting through the limit blocks and the clamping grooves.

[0013] In some embodiments, both the first protection plate and the second protection plate are arranged in a U shape.

[0014] Through the above solution, since both the first protection plate and the second protection plate are in a U shape, when a falling rock impacts on the first protection plate and the second protection plate, the impact force can be dispersed, avoiding the impact force acting point being too concentrated, resulting in the first protection plate and the second protection plate being unable to play a protective role.

[0015] In some embodiments, a groove is formed on one side of the second protection plate, and a movable rod is movably sleeved inside the groove. A buffer plate is fixedly installed on one side of the movable rod. Second sliders are symmetrically and fixedly installed on both sides of the buffer plate. The second sliders are movably sleeved inside second chutes. The second chutes are symmetrically formed inside the groove. A telescopic spring is fixedly installed at the bottom end of the buffer plate. The telescopic spring is movably sleeved on the outer wall of the movable rod.

[0016] Through the above solution, when a falling rock rolls and impacts on the second protection plate, the impact force pushes the buffer plate, causing the buffer plate to slide inward inside the groove, and also causing the second sliders to slide in the second chutes. The second sliders and the second chutes balance the sliding of the buffer plate, avoiding the impact force being too concentrated and causing the buffer plate to be unable to slide inward. When the buffer plate drives the movable rod to slide inside the groove, the telescopic spring contracts, and then through the telescopic acting force of the telescopic spring, the buffer plate is pushed to slide outward inside the groove to offset a certain impact force.

[0017] In some embodiments, magnets are installed on one side of both the groove and the buffer plate.

[0018] Through the above solution, when the buffer plate is pushed by an impact force to slide into the groove, the two magnets come into contact. Through the repulsive force between the magnets, the buffer plate is pushed to slide outwards, enabling the buffer plate to play a good reset role to offset a certain impact force.

[0019] The beneficial effects of the present utility model are as follows:

[0020] 1. By turning the rotating rod, the first bevel gear is driven to rotate through the meshing of the second bevel gear, causing the first support rod to move in a threaded manner on the surface of the threaded rod and slide upwards from inside the second support rod to adjust the overall length, thereby adjusting the angle with the cross plate, increasing the stability of the first protection plate and the second protection plate. Different support angles result in different stabilities of the first protection plate and the second protection plate. Therefore, the support can be adjusted according to the position and environment to achieve the best stability, improving the protection effect of the first protection plate and the second protection plate.

[0021] 2. When a falling rock rolls and hits the second protection plate, the impact force pushes the buffer plate, causing the buffer plate to slide inwards inside the groove and also causing the second slider to slide in the second chute. The second slider and the second chute balance the sliding of the buffer plate to prevent the impact force from being too concentrated and the buffer plate from being unable to slide inwards. When the buffer plate drives the movable rod to slide inside the groove, the telescopic spring contracts, and then through the telescopic force of the telescopic spring, the buffer plate is pushed to slide outwards inside the groove to offset a certain impact force, effectively alleviating the impact force on the first protection plate and the second protection plate and improving the protection effect of the first protection plate and the second protection plate.

[0035] To facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0036] The embodiments of the present application provide a falling rock protection device for mountain roads. As Figures 1 - 5 shown, it includes: a first protection plate 1, a cross plate 2 is fixedly embedded and connected to one side of the first protection plate 1, a first support rod 3 is hingedly installed on one side of the cross plate 2, a threaded rod 4 is threadedly connected to the bottom end of the first support rod 3, a first bevel gear 5 is fixedly installed on the outer wall of the threaded rod 4, a second bevel gear 6 is meshed and connected to the surface of the first bevel gear 5, a rotating rod 7 is fixedly installed on one side of the second bevel gear 6, the rotating rod 7 is movably sleeved on one side of the second support rod 8, the threaded rod 4 is movably sleeved inside the limiting groove 9, and the bottom of the first support rod 3 is movably sleeved inside the limiting groove 9.

[0037] By turning the rotating rod 7, the second bevel gear 6 is driven to rotate, and through the meshing of the second bevel gear 6, the first bevel gear 5 is driven to rotate, driving the threaded rod 4 to rotate inside the second support rod 8, so that the first support rod 3 moves in a threaded manner on the surface of the threaded rod 4 and slides upward from inside the second support rod 8 to adjust the overall length, thereby adjusting the angle with the cross plate 2 to increase the stabilizing effect of the first protection plate 1 and the second protection plate 16.

[0038] In the technical solution of the embodiment of the present application, first sliding grooves 10 are symmetrically formed inside the limit groove 9, and first sliders 11 are movably sleeved inside the first sliding grooves 10. The first sliders 11 are fixedly installed on the outer wall of the first support rod 3.

[0039] When the first support rod 3 is rotated and moves upward inside the second support rod 8, the first sliders 11 slide in the first sliding grooves 10. The first sliders 11 and the first sliding grooves 10 provide stability for the sliding of the first support rod 3. At the same time, the first sliders 11 and the first sliding grooves 10 also limit the sliding distance.

[0040] In the technical solution of the embodiment of the present application, a support base 12 is fixedly installed at the bottom end of the second support rod 8, and a ground nail 13 is fixedly embedded at the top end of the support base 12.

[0041] After the first support rod 3 and the second support rod 8 are used for support, the support base 12 is movably embedded into the soil, and then the ground nail 13 is movably embedded into the soil. The support base 12 and the ground nail 13 are used to increase the contact area at the bottom end of the second support rod 8 and provide stability for the support.

[0042] In the technical solution of the embodiment of the present application, clamping grooves 14 are symmetrically formed on both sides of the first protection plate 1, and limit blocks 15 are movably sleeved inside the clamping grooves 14. The limit blocks 15 are fixedly installed on one side of the second protection plate 16.

[0043] The limit blocks 15 are movably embedded into the clamping grooves 14, so that the second protection plate 16 is movably embedded into one side of the first protection plate 1, playing a good role in embedded connection. The docking installation is made more fitting through the limit blocks 15 and the clamping grooves 14.

[0044] In the technical solution of the embodiment of the present application, both the first protection plate 1 and the second protection plate 16 are arranged in a U shape.

[0045] Since both the first protection plate 1 and the second protection plate 16 are in a U shape, when a falling rock impacts on the first protection plate 1 and the second protection plate 16, the impact force can be dispersed, avoiding the impact force acting point being too concentrated, resulting in the first protection plate 1 and the second protection plate 16 being unable to play a protective role.

[0046] In the technical solution of the embodiment of the present application, a groove 17 is formed on one side of the second protection plate 16, an activity rod 18 is movably sleeved inside the groove 17, a buffer plate 19 is fixedly installed on one side of the activity rod 18, second sliders 21 are symmetrically and fixedly installed on both sides of the buffer plate 19, the second sliders 21 are movably sleeved inside second sliding grooves 22, the second sliding grooves 22 are symmetrically formed inside the groove 17, a telescopic spring 23 is fixedly installed at the bottom end of the buffer plate 19, and the telescopic spring 23 is movably sleeved on the outer wall of the activity rod 18.

[0047] After the falling rock rolls and impacts the second protection plate 16, the impact force pushes the buffer plate 19, causing the buffer plate 19 to slide inward within the groove 17, and also causing the second slider 21 to slide within the second chute 22. The second slider 21 and the second chute 22 balance the sliding of the buffer plate 19 to prevent the impact force from being too concentrated and causing the buffer plate 19 to be unable to slide inward. When the buffer plate 19 drives the movable rod 18 to slide within the groove 17, the telescopic spring 23 contracts. Then, through the telescopic force of the telescopic spring 23, the buffer plate 19 is pushed to slide outward within the groove 17 to offset a certain amount of impact force.

[0048] In the technical solution of the embodiment of the present application, magnets 20 are installed on one side of both the groove 17 and the buffer plate 19.

[0049] When the buffer plate 19 is pushed by the impact force to slide inward into the groove 17, the two magnets 20 come into contact. Through the repulsive force between the magnets, the buffer plate 19 is pushed to slide outward, enabling the buffer plate 19 to play a good reset role to offset a certain amount of impact force.
