Description

Technical Field

[0001] This utility model relates to the field of railway protection technology, specifically a railway line protection device. Background Technology

[0002] As a vital national transportation infrastructure, the safe operation of railway lines relies heavily on effective protective devices along the lines. Railway lines often traverse complex terrains such as mountains and hills, with numerous sloping sections of varying gradients on both sides. The quality of the protective devices installed in these areas directly impacts railway operational safety.

[0003] Traditional protective fences typically feature rigid, fixed connections between the horizontal bars and vertical posts, with no adjustable angle. When the support posts are adjusted to maintain verticality to adapt to sloping terrain, the connection between the horizontal bars and posts experiences torsional stress due to the angle deviation. This results in uneven fence joints, gaps, and an inability to tightly conform to the terrain for effective protection. While some protective devices offer slope adjustment, their adjustment structures are complex, and the fence itself lacks the adaptability to match the angle adjustments of the support posts. Installation requires on-site processing such as cutting and welding, which is cumbersome, inefficient, and unsuitable for rapid installation on slopes with varying gradients. Therefore, we have designed a railway line protective device that solves these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a railway line protection device to solve the problems mentioned in the background art.

[0005] By adopting the above technical solution, the railway protective fence can be synchronously adapted to the slope, eliminating the need for complex processing such as on-site cutting and welding, simplifying the installation process and ensuring the stability and sealing of railway protection on sloping sections.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a railway line protection device, including a base and a support column, wherein the support column is disposed above the base, and an inclined unit is disposed between the base and the support column. When the base is installed on a slope, the inclined unit is used to control the support column to always be in a vertical state, and an adjustable fence is disposed on one side of the support column. The adjustable fence includes vertical bars, an upper horizontal bar, a lower horizontal bar, and posts. The upper horizontal bar is rotatably connected to the upper end of the vertical bar, and the lower horizontal bar is rotatably connected to the lower end of the vertical bar. Multiple double-sphere joints arranged in a linear array are provided on the side of the upper and lower horizontal bars that are close to each other. The posts are connected to the upper and lower horizontal bars through the double-sphere joints. The double-sphere joints are used to adjust the connection angle between the posts and the upper and lower horizontal bars. When the upper and lower horizontal bars rotate, the posts can synchronously adapt to their rotation trajectory through the double-sphere joints.

[0007] Preferably, the upper and lower ends of the vertical rod are provided with arc-shaped interfaces, and a fixed shaft is fixedly connected to the inner wall of the arc-shaped interface. The upper and lower horizontal rods are rotatably connected to the fixed shaft.

[0008] Preferably, multiple ball holes arranged in a linear array are provided below the upper crossbar, above the lower crossbar, and at both ends of the column, and the two ends of the double ball joint are respectively engaged in the ball holes on the surface of the column and the upper or lower crossbar.

[0009] Preferably, a mounting bracket is fixedly connected to the side of the support column near the vertical rod, and the vertical rod is fixedly connected to the mounting bracket.

[0010] Preferably, the tilting unit includes an adjusting support, the bottom of which is fixedly connected to the base, and a rotating rod is rotatably connected to the inner wall of the adjusting support, the outer wall of which is fixedly connected to the bottom of the support column.

[0011] Preferably, the surface of the adjusting support is provided with a plurality of limiting holes arranged in an arc shape. The rotating rod passes through the adjusting support and extends to both ends. One end of the rotating rod is rotatably connected to a limiting rod. A bolt is inserted below the limiting rod. The end of the bolt away from the limiting rod passes through the limiting hole and extends outward. The bolt is used to fix the rotation angle of the support column.

[0012] Preferably, the rotating rod is located above the limiting hole, and the limiting hole is arranged in an arc with the rotating rod as the center.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This railway line protection device, through the inclined unit between the base and the support column, can quickly adjust and fix the angle of the support column to ensure that it remains vertical on the slope. Combined with the adjustable fence structure where the upper and lower horizontal bars rotate around the vertical bar and the column is connected to the horizontal bar through a double ball joint, the fence can synchronously adapt to the slope adjustment, effectively releasing the torsional stress during the adjustment process, avoiding splicing gaps and structural deformation, and eliminating the need for complex processing such as on-site cutting and welding. It not only ensures the stability of slope protection, but also simplifies the installation process, improves construction efficiency, and solves the slope adaptation problem of traditional protective fences when installed on slopes.

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.

[0017] Please see Figure 1-5 This utility model discloses a railway line protection device, including a base 1 and a support column 2. The support column 2 is disposed above the base 1. An inclined unit 3 is disposed between the base 1 and the support column 2. When the base 1 is installed on a slope, the inclined unit 3 is used to control the support column 2 to always be in a vertical state. An adjustable fence 4 is disposed on one side of the support column 2. The adjustable fence 4 includes a vertical bar 41, an upper horizontal bar 42, a lower horizontal bar 43, and a column 44. The upper horizontal bar 42 is rotatably connected to the upper end of the vertical bar 41. The lower horizontal bar 43 is rotatably connected to the lower end of the vertical bar 41. Multiple double-sphere joints 45 arranged in a linear array are provided on the side of the upper horizontal bar 42 and the lower horizontal bar 43 that are close to each other. The column 44 is connected to the upper horizontal bar 42 and the lower horizontal bar 43 through the double-sphere joints 45. The double-sphere joints 45 are used to adjust the connection angle between the column 44 and the upper horizontal bar 42 and the lower horizontal bar 43. When the upper horizontal bar 42 and the lower horizontal bar 43 rotate, the column 44 can synchronously adapt to their rotation trajectory through the double-sphere joints 45.

[0018] Furthermore, a mounting bracket 5 is fixedly connected to the side of the support column 2 near the vertical rod 41, and the vertical rod 41 is fixedly connected to the mounting bracket 5.

[0019] Furthermore, the tilting unit 3 includes an adjusting support 31, the bottom of which is fixedly connected to the base 1, and a rotating rod 32 is rotatably connected to the inner wall of the adjusting support 31. The outer wall of the rotating rod 32 is fixedly connected to the bottom of the support column 2.

[0020] Specifically disclosed, the surface of the adjusting support 31 is provided with multiple limiting holes 33 arranged in an arc shape. The rotating rod 32 passes through the adjusting support 31 and extends to both ends. One end of the rotating rod 32 is rotatably connected to a limiting rod 34. A bolt 35 is inserted below the limiting rod 34. The end of the bolt 35 away from the limiting rod 34 passes through the limiting hole 33 and extends outward. The bolt 35 is used to fix the angle of the support column 2. This structure is used to adjust the angle of the support column 2 on the slope to keep it in a vertical state.

[0021] It is particularly important to emphasize that the upper and lower ends of the vertical rod 41 are provided with arc-shaped interfaces 46, and the inner wall of the arc-shaped interfaces 46 is fixedly connected to a fixed shaft 47. The upper horizontal rod 42 and the lower horizontal rod 43 are rotatably connected to the fixed shaft 47. Multiple ball holes arranged in a linear array are provided below the upper horizontal rod 42, above the lower horizontal rod 43, and at both ends of the column 44. The two ends of the double ball joint 45 are respectively engaged in the ball holes on the surface of the column 44 and the upper horizontal rod 42 or the lower horizontal rod 43. This structure allows the column 44 to synchronously adapt to its rotation angle when the upper horizontal rod 42 and the lower horizontal rod 43 rotate, effectively releasing the torsional stress during the adjustment process.

[0022] It is important to emphasize that the rotating rod 32 is located above the limiting hole 33, which is an arc formed with the rotating rod 32 as the center. This structure ensures that the bolt 35 can be accurately inserted into the limiting hole 33.

[0023] Working principle: First, fix the base 1 at the preset position on the slope. Then, rotate the tilting unit 3 to make the bottom of the support column 2 rotate around the rotating rod 32 and adjust its angle to a vertical state. Then, use bolts 35 to pass through the limiting rod 34 and insert them into the corresponding arc-shaped limiting hole 33 on the surface of the adjusting support 31 and tighten them to fix it, thus completing the slope adaptation and fixing of the support column 2. Next, fix the vertical bar 41 of the adjustable fence 4 to the mounting support 5 on the support column 2. The upper horizontal bar 42 and the lower horizontal bar 43 rotate around the fixed shaft 47 in the arc interface 46 at both ends of the vertical bar 41. The column 44 flexibly adjusts the connection angle with the horizontal bar through the double ball joint 45 to adapt to the rotation trajectory synchronously, and finally completes the installation and slope adaptation of the slope protection device.
