Abstract
Description
Technical Field
[0001] This utility model relates to the field of mountain road facilities, and in particular to a rockfall protection shed buffer structure for mountain roads. Background Technology
[0002] For mountain roads, the sides are typically steep slopes. To prevent falling rocks from damaging the road surface, protective canopies are usually installed in sections prone to rockfalls and landslides. These canopies are located above the road surface, shielding it from direct impact by falling rocks.
[0003] Existing protective canopies primarily consist of vertical pillars erected on both sides of the road, with the canopy spanning across the road surface to intercept and guide falling rocks to either side. To further reduce the impact of falling rocks on the canopy, current solutions often include a buffer layer, such as a rubber or straw layer, on top of the canopy. This allows the falling rocks to directly contact the buffer, absorbing their kinetic energy. However, this design leads to rapid damage to the buffer structure from falling rocks, significantly increasing the frequency of replacement and maintenance costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a buffer structure for rockfall protection sheds on mountain roads that effectively improves the service life of protective sheds.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a rockfall protection canopy buffer structure for mountain roads, including a column, on which a protective canopy is set, the protective canopy including a buffer structure, the protective canopy including a top canopy and a bottom canopy, the bottom canopy being fixedly set on the column, and the top canopy and the bottom canopy being connected by the buffer structure.
[0006] Furthermore, the cushioning structure includes springs, which are evenly distributed between the top and bottom canopies.
[0007] Furthermore, a spring seat is provided on the wall of the base facing the spring, and the spring is fixedly installed on the spring seat, with the spring seat and spring being set in a one-to-one correspondence.
[0008] Furthermore, the buffer structure includes at least one limiting rod, which includes a first limiting rod and a second limiting rod. The first limiting rod and the second limiting rod are rotatably connected by a pivot. The first limiting rod is hinged to the bottom canopy, and the second limiting rod is hinged to the top canopy.
[0009] Furthermore, the limiting rods are evenly distributed along the outer perimeter of the protective shed between the top and bottom sheds.
[0010] Furthermore, the first limiting rod includes a first limiting pivot, and the bottom canopy includes a first bottom canopy limiting hole, with the first limiting pivot rotatably disposed within the first bottom canopy limiting hole.
[0011] Furthermore, the buffer structure includes a buffer rubber layer, which is disposed between the roof and the floor, with the bottom of the buffer rubber layer in close contact with the floor and the top of the buffer rubber layer in close contact with the roof.
[0012] Furthermore, it includes trusses, which are positioned between the columns and the base.
[0013] Furthermore, a first longitudinal main steel beam is installed on the outer perimeter of the base, a second longitudinal main steel beam is installed on the column, and a truss is installed between the first longitudinal main steel beam and the second longitudinal main steel beam.
[0014] Furthermore, a first transverse main steel beam is installed on the outer perimeter of the base, a second transverse main steel beam is installed on the column, and a truss is installed between the first transverse main steel beam and the second transverse main steel beam.
[0015] The beneficial effects of this utility model are as follows: 1. When a rock rolls down a steep slope onto the protective canopy, it contacts the canopy and impacts it. Under this violent impact, the canopy moves downwards along with the rock. At this time, the spring or buffer rubber layer of the buffer structure absorbs the impact on the canopy, making the base almost unaffected by the rock impact, effectively protecting the base and the columns below it. Simultaneously, because the canopy can move downwards to a certain extent immediately upon impact, it also protects the canopy well, preventing it from being damaged quickly by excessive impact force. 2. While the spring absorbs the impact on the canopy, a rotating limiting rod constrains the canopy and base, preventing the canopy from detaching from the buffer structure. When the canopy is impacted and moves downwards, the rotating limiting rod can adapt to the reduced distance between the canopy and base by rotating between the first and second limiting rods. Subsequently, it can adapt to the increased distance between the canopy and base when the canopy returns to its original position under the drive of the spring or buffer rubber layer. Third, the structural stability between the base and the columns is enhanced by using trusses, ensuring a stable connection between them. This invention is particularly suitable for rockfall protection sheds on mountain roads. Attached Figure Description

Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] like Figures 1 to 3 The image shows an embodiment of a rockfall protection canopy buffer structure for mountain roads. Figure 1 In the structure, column 1 is installed vertically, and a positioning welding plate 2 is installed on the top of column 1. The positioning welding plate 2 is fixedly connected to the second transverse main steel beam 61 and the second longitudinal main steel beam 31 to form a stable load-bearing foundation. Trusses 4 are installed on the second transverse main steel beam 61 and the second longitudinal main steel beam 31 to improve the stability of the structure. Above the trusses 4, the first transverse main steel beam 6 and the first longitudinal main steel beam 3 are installed. The first transverse main steel beam 6 and the first longitudinal main steel beam 3 are located on the outer periphery of the base 9, which is rectangular. The top 8 and the base 9 can be installed horizontally or at an angle to the horizontal plane.
[0022] Figure 2 In the design, a spring seat 91 is provided on the wall of the base 9 facing the spring 7. The spring seat 91 is cylindrical, protruding from the wall of the base 9 facing the spring 7 and arranged vertically. The spring 7 can be snapped onto the spring seat 91. The springs 7 and spring seats 91 are arranged in a one-to-one correspondence, ultimately ensuring that the springs 7 are evenly distributed between the top 8 and the base 9, forming a stable and uniform cushioning effect. Figure 1 and Figure 3 As shown, limit rods 5 are provided on the outer periphery of the roof 8 and the base 9. Among the limit rods 5, the first limit rod 51 and the second limit rod 52 are rotatably connected by a pivot 53. The free end of the first limit rod 51 is provided with a first limit pivot 55, and the free end of the second limit rod 52 is provided with a second limit pivot 54. Figure 1 and Figure 2 As shown, the base 9 is provided with a first base limiting hole 92, and the first limiting shaft 55 is rotatably disposed within the first base limiting hole 92. Similarly, the second limiting shaft 54 can also be rotatably connected to the corresponding limiting hole on the roof 8. The function of the spring 7 is mainly to allow the roof 8 to move downwards first when impacted by falling rocks, and then return to its original position. The function of the limiting rod is to ensure that the roof is always positioned above the spring 7, so that the spring 7 can continuously and reliably provide cushioning for the roof 8.
