[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 Figures 1-4 , a telescopic safety isolation fence for railway operations, comprising a mounting block 1, bolts 2, a guardrail mechanism 3, a protection block 7 and a limiting mechanism 8. The bolts 2 are arranged on the mounting block 1. The guardrail mechanism 3 includes an electric push rod 4, a connecting block 5 and a cone 6. One end of the electric push rod 4 is connected to the top of the mounting block 1, the other end of the electric push rod 4 is connected to one end of the connecting block 5, the other end of the connecting block 5 is connected to the cone 6, the protection block 7 is connected to the connecting block 5 through the limiting mechanism 8. The limiting mechanism 8 includes a limiting plate 9, a through groove 10, a first telescopic rod 11, a frame 12, a slotted opening 13 and a second telescopic rod 14. One end of the limiting plate 9 is connected to the side of the connecting block 5, the other end of the limiting plate 9 abuts against the protection block 7, the through groove 10 is opened on the protection block 7, one end of the first telescopic rod 11 is connected to the inner wall of the through groove 10, the other end of the first telescopic rod 11 is connected to the frame 12, both ends of the bottom of the frame 12 abut against the front and rear sides of the connecting block 5, the slotted opening 13 is opened on the connecting block 5, one end of the second telescopic rod 14 is connected to the inner wall of the through groove 10, and the other end of the second telescopic rod 14 extends into the interior of the frame 12. There are two limiting mechanisms 8.

[0023] When in use, first, the device can be installed at a specified position by the cooperation of the bolts 2 and the mounting block 1. Then, the second telescopic rod 14 is pushed to separate the second telescopic rod 14 from the frame 12. Then, the first telescopic rod 11 in the through groove 10 is pushed to drive the frame 12 to move by the first telescopic rod 11, so that the frame 12 moves to a position matching the slotted opening 13. Then, the protection block 7 is pushed to enable the frame 12 to pass through the slotted opening 13 and separate the protection block 7 from the limiting plate 9, so that the protection block 7 can be separated from the cone 6 and the cone 6 is exposed. The cone 6 can prevent people from climbing over the device. The height of the device can be adjusted by the electric push rod 4. When the device is not in use and is disassembled, the protection frame is connected to the connecting block 5 through the limiting mechanism 8 to cover the cone 6. Here, how to control the limiting mechanism 8 can be clearly inferred by those skilled in the art through the above steps and will not be described in detail here. The sizes and shapes of all components in this structure are not specifically limited here and need to be produced according to actual situations.

[0024] The stability of the above-mentioned limiting mechanism 8 is relatively poor. To solve this problem, in this embodiment, the two limiting mechanisms 8 are symmetrically arranged.

[0025] To improve the installation effect, in this embodiment, a plurality of bolts 2 are provided, and the plurality of bolts 2 are symmetrically arranged.

[0026] The above-mentioned mounting block 1 is prone to rust after long-term use. To solve this problem, in this embodiment, the mounting block 1 is made of stainless steel.

[0027] The anti-slip effect of the outer wall of the above-mentioned connecting block 5 is relatively poor. When the staff carry the device and hold the outer wall of the connecting block 5, the hands of the staff are prone to slip. To solve this problem, in this embodiment, the outer wall of the connecting block 5 is provided with an anti-slip layer, and the anti-slip layer is fixedly connected to the outer wall of the connecting block 5.

[0028] To improve the anti-slip effect, in this embodiment, the anti-slip layer is provided with anti-slip lines, and a plurality of anti-slip lines are provided.
