DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] See also Figure 1-3A guardrail for highway maintenance includes a protective structure for highway maintenance, the protective structure includes a base 1, a column 2 fixedly mounted on the upper surface of the base 1, a first connecting rod 3 and a second connecting rod 4 arranged outside the column 2 and rotatably connected, and a connecting piece fixedly mounted on one side of the column 2 and connected to the second connecting rod 4, a caster 19 is rotatably mounted on the lower surface of the base 1, the connecting piece includes a connecting block 5 welded to one side of the column 2 and a sliding rod 6 fixedly mounted on the bottom end of the second connecting rod 4, and a sliding opening 7 adapted to the sliding rod 6 is opened inside the connecting block 5.

[0028] In this embodiment, the number of the base 1, the column 2 and the connecting parts are all two, the number of the first connecting rod 3 and the second connecting rod 4 is multiple, and the multiple first connecting rods 3 and the second connecting rod 4 are crossed in a diamond shape, and the leftmost and rightmost first connecting rods 3 are hinged to the two columns 2.

[0029] It should be noted that there are eight casters 19 , and the eight casters 19 are equidistant and rectangularly mounted on the lower surfaces of the two bases 1 , and brake pads are disposed on the outside of the casters 19 .

[0030] When this embodiment is in use, the installation of casters 19 facilitates the displacement of the protective structure, so that it can be better transported, and at the same time facilitates the relative movement of the two columns 2, which not only facilitates the deployment of multiple diamond-shaped and crossed first connecting rods 3 and second connecting rods 4 to achieve a protective effect, but also allows for storage.

[0031] The two connecting members are symmetrically installed between the two columns 2, and the leftmost and rightmost second connecting rods 4 are respectively connected to the two connecting members.

[0032] In this embodiment, a warning structure is provided on the column 2; the warning structure includes a reflective strip 8 fixedly mounted on the outer wall of the column 2 and a warning light 9 mounted on the upper surface of the column 2 by bolts. The reflective strip 8 and the warning light 9 can play a warning role and are more convenient for the protection of the protective structure.

[0033] In this embodiment, the two bases 1 are provided with connection components for connecting with other protective structures, and the connection components are composed of a splicing block 10 and a splicing groove 11. The splicing block 10 is fixedly mounted on the side wall of one of the bases 1, and the splicing groove 11 is opened inside the other base 1 and away from the splicing block 10. Through the splicing block 10 and the splicing groove 11, two adjacent protective structures can be spliced ​​to increase the protection range.

[0034] Embodiment 2:

[0035] See also Figure 4On the basis of the first embodiment, a shielding mechanism is provided on the two columns 2, and the shielding mechanism includes a winding roller 12 rotatably installed inside the right column 2, a servo motor 13 fixedly installed on the inner top wall of the right column 2, a protective net 14 wound around the outer surface of the winding roller 12 and extending to the outside of the right column 2, a baffle 15 welded to the other side of the protective net 14, and an insert 16 fixedly installed on the side of the baffle 15 away from the protective net 14 and plugged into the left column 2.

[0036] The right column 2 has a movable opening inside, and the protective net 14 extends to the outside of the right column 2 through the movable opening. The left column 2 has a slot and a through hole inside, and the insert block 16 has a positioning hole 17 inside, and a positioning rod 18 extending into the slot and matching the positioning hole 17 is inserted into the through hole. The winding roller 12 is provided with a stopper for fixing one end of the protective net 14.

[0037] It should be noted that the blocking bar 15 is larger than the movable opening, so as to prevent the protective net 14 from extending as a whole into the interior of the column 2 .

[0038] By adopting the above technical solution, the servo motor 13 drives the winding roller 12 to rotate and unwind the protective net 14, so that the protective net 14 can be pulled out for shielding work. After the protective net 14 is unfolded, the insert block 16 is inserted into the left column 2 and fixed by the positioning rod 18 to strengthen the protection of the protective net 14.

[0039] The working principle of the above embodiment is:

[0040] When in use, the installation of casters 19 facilitates the displacement of the protective structure, so that it can be better transported, and at the same time facilitates the relative movement of the two columns 2, which not only facilitates the deployment of multiple diamond-shaped and crossed first connecting rods 3 and second connecting rods 4 to achieve a protective effect, but also allows for storage.

[0041] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
