Description

Technical Field

[0001] The utility model relates to the technical field of railway engineering construction, in particular to a protective net structure used for railway engineering construction. Background Art

[0002] During railway construction, protective nets need to be set up on both sides of the railway to isolate pedestrians and livestock from entering the railway line, thereby affecting the passage of trains. At the same time, falling rocks and objects on the high slopes on both sides of the railway cause damage to the railway line and trains, while also improving slope stability.

[0003] The existing patent announcement number CN213869267U discloses a combined railway protection net, which includes a T-pin and a fixed sleeve. When in use, when herders need to cross the railway track for grazing, the T-pin is manually moved out of the fixed sleeve, and the protection net doors on both sides of the railway track are all opened inward to 90 degrees, and then the T-pins on both sides are manually moved into the corresponding fixed sleeves to form a horizontal railway track protection net; when the herd successfully passes the railway track, the T-pin is moved out of the fixed sleeve, the protection net doors on both sides of the railway track are all closed, and finally the T-pins on both sides are manually moved into the fixed sleeves again.

[0004] When assembling the above device, screws are used to fix the installation between the protective net door and the doorpost. It is troublesome to fix groups of protective net doors, and the installation efficiency still needs to be improved. In view of the above problems, a protective net structure for railway engineering construction is proposed. Utility Model Content

[0024] Please refer to Figures 1 - 3 , in this embodiment, a protective net structure for railway engineering construction includes several groups of vertical columns 11 and protective net plates 12. Both ends of the top of the protective net plate 12 are fixedly connected with installation blocks 15. An installation groove 13 for fitting the installation blocks 15 to be inserted is opened at the top of the vertical column 11. A groove 14 is opened at the bottom of the inner wall of the installation groove 13. A fixing block 16 is fixedly connected to the bottom of the inner wall of the groove 14. Positioning blocks 17 are rotatably connected to both sides of the fixing block 16. A positioning groove 20 for fitting the positioning blocks 17 to be inserted is opened on one side of the installation block 15. A pushing assembly for pushing the positioning blocks 17 to be inserted into the positioning groove 20 is arranged on one side of the vertical column 11;

[0025] A limiting assembly for limiting the protective net plate 12 is arranged on one side of the vertical column 11. The protective net plate 12 slides downward in the two installation grooves 13, so that the installation blocks 15 are inserted into the installation grooves 13. The limiting assembly limits the protective net plate 12, and the pushing assembly makes the positioning blocks 17 inserted into the positioning grooves 20 to fix the two installation blocks 15, which can facilitate the installation and fixation of the protective net plate 12 and is also convenient for disassembly and replacement.

[0026] The pushing assembly includes a moving block 19 and a threaded rod 18. The moving block 19 is slidably connected between the two groups of positioning blocks 17. One side of the moving block 19 is rotatably connected to the threaded rod 18. The threaded rod 18 is threadedly connected to one side of the column 11. The threaded rod 18 is rotated inward, and the threaded rod 18 drives the moving block 19 to slide between the two groups of positioning blocks 17, so that the positioning block 17 is stuck in the positioning groove 20, and the two groups of mounting blocks 15 can be fixed.

[0027] The limiting assembly includes two groups of fixing bars 21, and the two groups of fixing bars 21 are respectively fixedly connected to the two sides of the protective mesh plate 12. Both sides of the column 11 are provided with columns 11 for sliding with the fixing bars 21, which can limit the protective mesh plate 12, facilitate the installation and fixation of the protective mesh plate 12, and reduce the shaking or falling off of the protective mesh plate 12.

[0028] Two sets of limit plates 23 are fixedly connected to both sides of the column 11, and the adjacent sides of the two sets of limit plates 23 are slidably matched with the two sides of the protective mesh plate 12. By setting the limit plates 23, the protective mesh plate 12 can be fixed to reduce the movement of the protective mesh plate 12.

[0029] An extension block 25 is fixedly connected to the bottom of the column 11, and mounting plates 26 are fixedly connected to both sides of the column 11 away from the protective mesh plate 12. By providing the extension block 25 and the mounting plate 26, the column 11 can be easily installed and fixed.

[0030] A top cover 24 is clamped on the top of the column 11 . By providing the top cover 24 , the threaded rod 18 can be limited and dust and rainwater can be prevented from entering the installation groove 13 .

[0031] The working principle of the utility model is as follows: when installing, first use external tools to insert two groups of columns 11 into the ground through the extension block 25, then use screws to fix the mounting plate 26, and insert a group of protective mesh panels 12 into the fixing grooves 22 through the fixing strips 21 on both sides, and the protective mesh panels 12 slide downward in the two groups of mounting grooves 13, so that the mounting block 15 is stuck in the mounting groove 13, and the threaded rod 18 is rotated inward, and the threaded rod 18 drives the moving block 19 to slide between the two groups of positioning blocks 17, so that The positioning blocks 17 are inserted into the positioning grooves 20 to fix the two sets of mounting blocks 15, and then the top cover 24 is stuck on the column 11. When disassembling, the top cover 24 is pulled out upwards and the threaded rod 18 is rotated. The threaded rod 18 drives the moving block 19 to slide to one side, so that the two sets of positioning blocks 17 are not restricted by the moving block 19. The staff rotates the two sets of positioning blocks 17 to disengage the positioning blocks 17 from the positioning grooves 20, and then pulls the protective mesh plate 12 upwards to disengage the fixing strip 21 from the fixing groove 22 to complete the disassembly.

[0032] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
