Description

Technical Field

[0001] The utility model belongs to the technical field of railway protection fences, and more specifically, particularly relates to an impact-resistant railway protection fence. Background Art

[0002] Railway protective fence is a fence system used to protect railway lines and prevent people, animals or objects from accidentally entering the railway tracks. It is usually made of metal materials (such as steel, aluminum alloy, etc.) and has a certain height and strength. Railway protective fence plays an important role in ensuring railway safety, preventing accidents, protecting railway facilities and the surrounding environment. It is an indispensable part of the railway transportation system.

[0003] Some of the current railway protective fences are usually fixed. When hit by people, animals or objects, they directly bear all the impact forces. The protective fences are prone to deformation, which will affect the normal use of the protective fences.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and an impact-resistant railway protective fence is provided to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an impact-resistant railway protective fence, which is achieved by the following specific technical means:

[0006] A shock-resistant railway protective fence comprises a support column and a protective net, wherein a pair of connecting grooves are provided on both sides of the support column, a connecting block is installed in the connecting groove, a mounting block is installed on one side of the connecting block, a slide groove 1 is provided on one side of the mounting block, a "T"-shaped block is slidably connected in the slide groove 1, a slide groove 2 is provided at the lower end of the support column, a screw rod is rotatably connected in the slide groove 2, a slider is penetrated and connected to the periphery of the screw rod, a pair of diagonal bracing rods are installed on both sides of the slider, a chamber is provided above the slide groove 2 in the support column, a driven bevel gear is installed on the bottom of the chamber at the top of the screw rod, a rotating shaft is rotatably connected to one side of the chamber, an active bevel gear is installed on one end of the rotating shaft, a pair of support blocks are installed on both sides of the protective net, and one end of the support block is connected to one side of the "T"-shaped block.

[0007] Furthermore, a pair of springs are installed on both sides of the slide slot 1, and opposite ends of the pair of springs are connected to both sides of the "T"-shaped block.

[0008] Furthermore, a fixing nail is installed on one side of the bottom end surface of the diagonal support rod.

[0009] Furthermore, a rotating block is installed on one side of one end of the rotating shaft that passes through the chamber.

[0010] Furthermore, a support seat is installed at the bottom end of the support column.

[0011] Furthermore, the driving bevel gear and the driven bevel gear are meshed with each other.

[0012] Furthermore, the screw rod is threadably connected to the slider.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the coordinated use of springs and "T"-shaped blocks, when the protective net is hit, the protective net moves forward under the impact force, and the protective net drives a pair of support blocks on both sides to move forward, and the support blocks drive the "T"-shaped blocks to move forward. When the "T"-shaped blocks move forward, the impact force acts on the spring, and the spring can play a certain buffering role on the impact force, thereby effectively reducing the possibility of deformation of the protective fence when it is hit, thereby improving the use effect of the protective fence.

[0015] By using a rotating block, a rotating shaft, an active bevel gear, a driven bevel gear, a screw rod, a slider, an oblique support rod and a fixing nail in coordination, when the support seat at the bottom end of the support column is installed on the base, the rotating block is rotated with the help of a tool, the rotating block drives the rotating shaft to rotate, and the rotating shaft drives the active bevel gear to rotate. Since the active bevel gear and the driven bevel gear are meshed with each other, the active bevel gear drives the driven bevel gear to rotate when it rotates, and the driven bevel gear drives the screw rod to rotate. Since the screw rod is threadedly connected to the slider, the slider is driven to move downward when the screw rod rotates, and the slider drives a pair of oblique support rods to move downward, and the oblique support rods drive the fixing nails to move downward and insert into the ground, thereby improving the stability of the protective fence, and further improving the impact resistance of the protective fence.

[0029] Among them, a pair of springs 401 are installed on both sides of the slide groove 302, and the opposite ends of the pair of springs 401 are connected to the two sides of the "T"-shaped block 4. When the "T"-shaped block 4 moves forward, the impact force acts on the spring 401. The spring 401 can play a certain buffering role on the impact force, thereby reducing the degree of damage to the protective net 2 when it is hit.

[0030] Among them, a fixing nail 701 is installed on one side of the bottom end surface of the diagonal support rod 7, and the diagonal support rod 7 drives the fixing nail 701 to move downward and insert into the ground, thereby improving the stability of the protective fence.

When the "T" block 4 moves forward, the impact force acts on the spring 401, and the spring 401 can play a certain buffering role on the impact force, thereby effectively reducing the possibility of deformation of the protective fence when it is hit, thereby improving the use effect of the protective fence. By using the rotating block 902, the rotating shaft 9, the active bevel gear 901, the driven bevel gear 602, the screw rod 6, the slider 601, the diagonal support rod 7 and the fixing nail 701 in coordination, when the support When the support seat 102 at the bottom end of the column 1 is installed on the base, the rotating block 902 is rotated with the help of a tool, and the rotating block 902 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the active bevel gear 901 to rotate. Since the active bevel gear 901 and the driven bevel gear 602 are meshed with each other, the active bevel gear 901 drives the driven bevel gear 602 to rotate when it rotates, and the driven bevel gear 602 drives the screw rod 6 to rotate. Since the screw rod 6 is threadedly connected to the slider 601, the slider 601 is driven to move downward when the screw rod 6 rotates, and the slider 601 drives a pair of diagonal support rods 7 to move downward, and the diagonal support rods 7 drive the fixing nails 701 to move downward and insert into the ground, thereby improving the stability of the protective fence, and then improving the impact resistance of the protective fence.
