Technical Field

[0001] The utility model relates to the field of anti-climbing nets for high-speed railways, in particular to a barbed wire net for anti-climbing nets for high-speed railways. Background Art

[0002] In the security protection system of high-speed railways, razor wire mesh is an important anti-intrusion device. It shoulders the important task of preventing unauthorized personnel from climbing over the railway fence and ensuring the safety of railway operations and facilities along the line. However, the existing razor wire mesh has gradually exposed some problems that need to be solved in actual application.

[0003] At present, the barbed wires of traditional barbed wire mesh are mostly connected to the mesh frame by welding or integrated fixing. As time goes by, the barbed wires are exposed to the outside for a long time and are eroded by harsh natural environments such as wind, sun, rain, snow and frost. They are very prone to damage such as rust and breakage. When some barbed wires are damaged and need to be replaced, maintenance personnel often face huge challenges due to the limitations of their fixing methods. Moreover, on the long lines of high-speed railways, barbed wire mesh needs to be spliced ​​in multiple sections to achieve continuous protection. The existing method of connecting adjacent barbed wire meshes has many inconveniences. Common connection structures either have a cumbersome installation process and require numerous bolts and nuts to fix. Therefore, it is necessary to design a high-speed railway anti-climbing barbed wire mesh to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a high-speed railway anti-climbing barbed wire net to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a barbed wire net for anti-climbing and stabbing for high-speed railways, comprising a mounting frame, a barbed wire mesh panel being slidably connected to the right side of the mounting frame via an opening, limit plates being fixedly mounted on the front and rear sides of the top and bottom of the inner cavity of the mounting frame, a rotating column being rotatably connected to the right side of the inner cavity of the mounting frame via an opening, and a movable opening for use in conjunction with the barbed wire mesh panel being provided on the right side of the rotating column.

[0006] Preferably, support rods are fixedly installed above and below the left side of the installation frame, an insertion rod is fixedly installed on the left side of the support rod, and limiting openings for use with the support rods are opened above and below the rear part of the inner cavity of the movable port.

[0007] Preferably, a sleeve is fixedly mounted on the top of the rotating column, the top of the sleeve passes through the mounting frame and extends to the outside of the mounting frame, and a spring is welded to the bottom of the inner cavity of the sleeve.

[0008] Preferably, a square rod is welded to the top end of the spring.

[0009] Preferably, a limit bar is fixedly installed on the top end of the square rod.

[0010] Preferably, a limiting frame used in conjunction with the limiting bar is fixedly installed on the left side of the top of the installation frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The high-speed railway anti-climbing barbed wire mesh is provided with a limit plate so that the limit strip can be in close contact with the front and rear of the barbed wire mesh panel, thereby achieving the effect of limiting the barbed wire mesh panel, and then by rotating the sleeve, the sleeve drives the rotating column to rotate, and the rotation of the rotating column can achieve the effect of limiting the barbed wire mesh panel to the inner side of the installation frame.

Example

[0021] Please refer to Figure 1-5 As shown, the utility model provides a barbed wire net for anti-climbing and stabbing for high-speed railways, comprising a mounting frame 1, a barbed wire mesh panel 2 being slidably connected to the right side of the mounting frame 1 through an opening, limit plates 3 being fixedly mounted on the front and rear sides of the top and bottom of the inner cavity of the mounting frame 1, a rotating column 4 being rotatably connected to the right side of the inner cavity of the mounting frame 1 through an opening, and a movable opening 5 for use in conjunction with the barbed wire mesh panel 2 being provided on the right side of the rotating column 4.

[0022] The cam 7 is fixed on the left side of the mounting frame 1, and the left side of the mounting frame 1 is fixedly provided with a support rod 6. The upper and lower parts of the rear part of the inner cavity of the movable opening 5 are provided with a limit opening 8 used in conjunction with the support rod 6. By setting the limit plate 3, the limit plate 3 can be tightly attached to the front and rear parts of the knife barbed wire mesh plate 2 to achieve the effect of limiting the knife barbed wire mesh plate 2. Then, by rotating the sleeve 9, the sleeve 9 drives the rotating column 4 to rotate, and the rotating column 4 rotates to drive the movable opening 5 to move. After the movable opening 5 moves, the knife barbed wire mesh plate 2 can be limited to the inner side of the mounting frame 1. When it is necessary to dock the two mounting frames 1, the plugging rod 7 on the left side of the right mounting frame 1 can be inserted into the inner side of the movable opening 5, and then the sleeve 9 is rotated. The sleeve 9 rotates and drives the rotating column 4 to rotate. The rotating column 4 rotates and limits the plugging rod 7 through the limit opening 8 and the support rod 6, thereby achieving the effect of quickly fixing the two mounting frames 1.

[0023] Specifically, a sleeve 9 is fixedly installed on the top of the rotating column 4, and the top of the sleeve 9 passes through the mounting frame 1 and extends to the outside of the mounting frame 1. A spring 10 is welded to the bottom of the inner cavity of the sleeve 9, and a square rod 11 is welded to the top of the spring 10. A limit bar 12 is fixedly installed on the top of the square rod 11, and a limit frame 13 used in conjunction with the limit bar 12 is fixedly installed on the left side of the top of the mounting frame 1. By setting the limit bar 12 and the limit frame 13, the sleeve 9 can pull the limit bar 12 upward when rotating. After the limit bar 12 is rotated ninety degrees, the limit bar 12 is released, and the limit bar 12 can be pulled into the inside of the limit frame 13 by the elastic force of the spring 10, thereby achieving the effect of limiting and fixing the rotating column 4 after rotation.

[0024] Working principle: The utility model is a kind of anti-climbing barbed wire mesh for high-speed railway. By setting the limiting plate 3, the limiting plate 3 can be closely attached to the front and rear of the barbed wire mesh panel 2, so as to achieve the effect of limiting the barbed wire mesh panel 2. Then, by rotating the sleeve 9, the sleeve 9 drives the rotating column 4 to rotate, and the rotating column 4 drives the movable opening 5 to move. After the movable opening 5 moves, the barbed wire mesh panel 2 can be limited to the inner side of the installation frame 1. When the two installation frames 1 need to be docked, the insertion rod 7 on the left side of the right installation frame 1 can be inserted into the movable opening 5. The inner side of the sleeve 9 is then rotated, and the rotation of the sleeve 9 drives the rotating column 4 to rotate. The rotation of the rotating column 4 can limit the insertion rod 7 through the limit opening 8 and the support rod 6, thereby achieving the effect of quickly fixing the two installation frames 1. At the same time, by setting the limit bar 12 and the limit frame 13, the sleeve 9 can pull the limit bar 12 upward when rotating. After the limit bar 12 is rotated ninety degrees, the limit bar 12 is released, and the limit bar 12 can be pulled into the interior of the limit frame 13 by the elastic force of the spring 10, thereby achieving the effect of limiting and fixing the rotating column 4 after rotation.
