Description

Technical Field

[0001] The utility model relates to the technical field of railway protection nets, in particular to a protection fence for railway engineering design. Background Art

[0002] The protection fences in railway engineering design are mainly used to ensure railway operation safety and environmental protection. They are divided into several categories according to different uses. The protection fences mainly prevent unauthorized people from entering the railway area, usually adopting anti-climbing designs and corrosion-resistant materials. And the protection nets set therein are used in key areas such as bridges and tunnels to prevent falling rocks or falling objects from invading the track.

[0003] After retrieval, a protection fence for railway engineering design with the publication number CN219118953U includes several vertical poles and several protection nets. The several vertical poles and the several protection nets are connected in sequence, and the several vertical poles are fixedly connected to the ground; it also includes a connection component and a support component. The connection component is used to limit and fix the vertical poles and the protection nets; the support component includes several support columns, and the several support columns are arranged around the side wall of the vertical pole; one end of the support column abuts against the side wall of the vertical pole, and the other end supports on the ground. This application has the effect of reducing the possibility that the vertical pole topples when being impacted by an external force, resulting in damage and detachment of the vertical pole and the protection net.

[0004] Based on the above patent, when the connection part between the vertical pole and the protection net is impacted by the external force of an animal or a vehicle in the background art, the huge impact force easily causes the vertical pole to topple, and thus the binding strips or bolts at the connection between the protection net and the vertical pole are easily loosened and detached due to being pulled, resulting in the detachment between the protection net and the vertical pole, which affects the subsequent use of the protection fence. In view of this technical problem, this application proposes a protection fence for railway engineering design. Summary of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0030] Refer to Figures 2 - 4 , an embodiment provided by the present invention: a protective fence for railway engineering design, including a guard net frame 1. Both inner walls of the left and right sides of the bottom end of the guard net frame 1 are rotatably connected with first screws 3. Refer to Figure 1 , both the left and right sides of the bottom end of the guard net frame 1 are fixedly connected with cutting rods 2. The top end of the guard net frame 1 is fixedly connected with a protection net 4. A moving block 5 is threadedly connected to the outer wall of the first screw 3. The outer wall of the moving block 5 is slidably connected to the inner walls of the left and right ends of the guard net frame 1. Fixing blocks 7 are connected to the front, back, left, and right sides of the guard net frame 1. Support rods 6 are rotatably connected to the front and back ends of the moving block 5. The opposite ends of the support rods 6 are respectively rotatably connected to the opposite ends of the auxiliary plates 12. The bottom sides of the opposite ends of the auxiliary plates 12 are respectively rotatably connected to the front, back, left, and right sides of the guard net frame 1. Connecting plates 8 are rotatably connected to the opposite ends of the fixing blocks 7. The bottom ends of the connecting plates 8 are rotatably connected to the footrests 10. A transfer plate 14 is slidably connected to the inner wall of the connecting plate 8. Transfer plates 14 are rotatably connected to the opposite ends of the left and right auxiliary plates 12. Pulling rods 9 are rotatably connected to the opposite ends of the transfer plates 14. The bottom sides of the opposite ends of the pulling rods 9 are rotatably connected to sliders 15. The inner walls of the sliders 15 are slidably connected to the outer walls of the sliding rods 16.

[0031] Specifically: After the cutting rods 2 on the protective net frame 1 are inserted into the soil, the protective net 11 and the protection net 4 can effectively ensure the safety of the railway. After installing the cutting rods 2, by rotating the first screw rod 3, the moving block 5 can be driven to move along the support rod 6. As the moving block moves, the auxiliary plate 12 displaces with the cooperation of the transfer plate 14, thereby driving the connecting plate 8 to rotate at the support of the fixed block 7. This rotation causes the connecting plate 8 to expand outward, providing better support and stability for subsequent operations. At the same time, when the transfer plate 14 displaces, it will pull the traction rod 9, causing the traction rod 9 to drive the slider 15 to move along the slide rod 16. As the slider moves, the footrest 10 will rotate and gradually adjust to a state that fits the ground. This process enables the footrest 10 to contact the ground more firmly, thereby providing additional support force for the entire device. Through this design, the footrest 10 and the connecting plate 8 can cooperate with each other to jointly support the stability and steadiness of the device on the ground, ensuring that it can withstand external forces or vibrations. In addition, this support mechanism not only enhances the stability of the device but also greatly improves the adaptability of the device for use in different environments, ensuring that it can exert its maximum effectiveness under various complex terrain conditions.

[0032] Refer to Figures 5 - 7 , for the protective net 11, threaded tubes 17 are threadedly connected to the four corners of the outer wall of the protective net frame 1. The rear ends of the threaded tubes 17 are rotatably connected to the adjusting blocks 18. The front ends of the adjusting blocks 18 are fixedly connected to the rear ends of the second screw rods 19. The outer walls of the second screw rods 19 are threadedly connected to the moving pieces 20. The four sides of the outer walls of the moving pieces 20 are rotatably connected to the connecting rods 21. The opposite ends of the connecting rods 21 are rotatably connected to the opposite ends of the clamping plates 22. The opposite ends of the clamping plates 22 are rotatably connected to the fitting blocks 13. The rear ends of the fitting blocks 13 are fixedly connected to the front ends of the threaded tubes 17.

[0033] Specifically: When it is necessary to replace the protective net 11, first rotate the threaded tube 17 to extend it axially to provide sufficient space for subsequent operations. Then, rotate the adjusting block 18. This action drives the moving piece 20 to move inside the threaded tube 17 through the second screw rod 19. As the moving piece 20 displaces, it will drive the connecting rod 21, thereby causing the clamping plate 22 to contract. At this time, the contraction of the clamping plate 22 will cause it to close at the inner wall of the threaded tube 17, creating conditions for the disassembly of the protective net 11. When the clamping plate 22 is successfully closed, continue to rotate the threaded tube 17. As the threaded tube 17 rotates, it will gradually disconnect from the protective net frame 1 and the protective net 11. In this way, the protective net 11 can be smoothly removed from the protective net frame 1. This design makes the entire replacement process more convenient and also ensures the smoothness of the operation during maintenance and repair. Through this series of actions, the operator can easily disassemble the old protective net 11 from the device for convenient replacement.

[0034] Working principle: After the cutting rod 2 at the guard net frame 1 is inserted into the soil, the protection net 11 and the protection net 4 ensure the safety of the railway. After installing the cutting rod 2, rotate the first screw rod 3 to make the moving block 5 drive the auxiliary plate 12 through the support rod 6, and with the cooperation of the adapter plate 14, the connecting plate 8 rotates at the fixed block 7, so that the connecting plate 8 opens outwards. When the adapter plate 14 displaces, the adapter plate 14 pulls the traction rod 9 to make the traction rod 9 move the slider 15 along the slide rod 16, so that the footrest 10 rotates, so that the footrest 10 further fits on the ground, so as to facilitate the footrest 10 to cooperate with the connecting plate 8 to support on the ground to provide more supporting force. When the protection net 11 needs to be replaced, rotate the threaded pipe 17 to extend it. Then, when rotating the adjusting block 18, the adjusting block 18 drives the moving piece 20 to move in the threaded pipe 17 through the second screw rod 19, and the moving piece 20 drives the connecting rod 21 to make the clamping plate 22 contract, so that the clamping plate 22 closes at the threaded pipe 17. After continuing to rotate the threaded pipe 17, the threaded pipe 17 falls off through the guard net frame 1 and the protection net 11, so as to facilitate removing the protection net 11 from the guard net frame 1 and facilitating the device to replace the protection net 11.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
