Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 5 A quickly foldable and deployable isolation guardrail for tunnel maintenance provided by the present utility model includes a first guardrail 1 and a second guardrail 2.

[0026] Referring to Figures 1 - 5 As shown, a second guardrail 2 is provided on one side of the first guardrail 1. A folding structure 3 is hinged on one side of the first guardrail 1. The folding structure 3 includes a hinge rod 301, a positioning plate 302, a clamping hole 303, a limiting hole 304 and a clamping rod 305. The hinge rod 301 is hinged to one side of the first guardrail 1. Positioning plates 302 are hinged on both sides of the first guardrail 1. A clamping hole 303 is opened on the side of the positioning plate 302 away from the first guardrail 1. Limiting holes 304 are opened on both sides of the second guardrail 2. Clamping rods 305 are arranged inside the clamping holes 303. The side of the hinge rod 301 away from the first guardrail 1 is hinged to the side of the second guardrail 2. The first guardrail 1 and the second guardrail 2 are connected to each other through the hinge rod 301. The positioning plates 302 are symmetrically distributed on both sides of the first guardrail 1. The limiting holes 304 are symmetrically distributed on both sides of the second guardrail 2. One side of the clamping rod 305 extends into the limiting hole 304. The clamping hole 303 and the limiting hole 304 form a clamping structure through the clamping rod 305.

[0027] During the process of tunnel maintenance, in order to prevent people from entering, etc., it is necessary to use guardrails to play a warning role. In the actual use process, through the setting of a folding structure 3, the first guardrail rod 1 and the second guardrail rod 2 of the device are connected by a hinge rod 301, so as to facilitate stretching and change the distance between the first guardrail rod 1 and the second guardrail rod 2. And during the storage process, in order to prevent it from loosening, the positioning plate 302 is rotated, so that the clamping rod 305 extends into the limiting hole 304 through the clamping hole 303 for clamping and positioning, thus facilitating storage and greatly increasing the practicability of the device.

[0028] Refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, anti-slip blocks 4 are installed on both sides of the bottoms of the first guardrail rod 1 and the second guardrail rod 2, and support structures 5 are provided on both sides of the first guardrail rod 1 and the second guardrail rod 2. The support structure 5 includes a storage groove 501, a support plate 502, a through hole 503, a positioning bolt 504 and a threaded hole 505. The storage grooves 501 are opened on both sides of the first guardrail rod 1 and the second guardrail rod 2. The support plates 502 are hinged inside the storage grooves 501. Through holes 503 are opened on one side of the support plates 502. The positioning bolts 504 are arranged inside the through holes 503. The threaded holes 505 are opened on both sides inside the storage grooves 501. The storage grooves 501 are symmetrically distributed on both sides of the first guardrail rod 1 and the second guardrail rod 2. The bottom ends of the support plates 502 are at the same horizontal height as the bottom ends of the anti-slip blocks 4. One side of the positioning bolt 504 extends into the threaded hole 505. The through hole 503 and the threaded hole 505 are threadedly connected by the positioning bolt 504.

[0029] During the process of using the guardrail, it may tilt, etc., thus affecting its overall use effect. Therefore, by setting a support structure 5 at its bottom, the support plate 502 is turned out during use, so as to play an auxiliary supporting role for the guardrail. And multiple groups of support plates 502 are provided, thus effectively preventing tilting and greatly increasing the functionality of the device.

[0030] During the process of using the device, the clamping rod 305 is pulled out to release the limit between the first guardrail rod 1 and the second guardrail rod 2, so as to facilitate adjusting the distance between the first guardrail rod 1 and the second guardrail rod 2 through the hinge rod 301. And after placing, the positioning bolts 504 inside the support plates 502 in the storage grooves 501 at the bottoms of the first guardrail rod 1 and the second guardrail rod 2 are removed to release the positioning, so as to facilitate turning them out to play an auxiliary supporting role, and thus facilitate the folding and unfolding use.

[0031] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described 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 utility model shall be included within the protection scope of the present utility model.
