Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0024] First embodiment:

[0025] like Figures 1-4 As shown, the highway construction safety guardrail provided by this utility model includes: a guard frame 100, which includes two protective beams 101. The bottom of the two protective beams 101 is open, and a base 102 is also provided at the bottom of the two protective beams 101. The protective beams 101 also have limiting cavities 103. One side of the limiting cavity 103 has an opening. A protective component 300 is engaged in the limiting cavity 103. The protective component 300 includes two positioning beams 301. Multiple positioning grooves 303 are arrayed on one side of the two positioning beams 301. One end of the positioning groove 303 has a groove. Each of the multiple positioning grooves 303 is equipped with a pre-tightening bolt 304. The positioning grooves symmetrically arranged on the two positioning beams 301 are... The crossbeam 400 is engaged by a common locking mechanism 303. Both ends of the crossbeam 400 are provided with positioning holes. The crossbeam 400 is fixedly installed by the pre-tightening bolts 304 installed in the positioning grooves 303. In actual use, the operator places the positioning rod 201 vertically, and then puts the protective beam 101 around the positioning rod 201. After it is in place, the operator puts the positioning beam 301 inside the positioning rod 201. At this time, the limiting cavity 103 of the protective beam 101, the positioning rod 201, and the positioning beam 301 fit tightly together. After the positioning beam 301 is installed, the operator aligns the multiple crossbeams 400 into the positioning grooves 303 at both ends of the positioning beam 301, and then fixes them with the pre-tightening bolts 304.

[0026] By using the protective beam 101, the limiting component 200, and the crossbeam 400 together, and through the use of the positioning beam 301 and positioning groove 303 in the limiting component 200, the crossbeam 400 can be quickly assembled. At the same time, the pre-tightening bolt 304 on the positioning groove 303 can ensure the stable installation of the crossbeam 400. The guardrail, which can be assembled by quick disassembly, can be quickly erected or dismantled according to the construction progress and needs, which greatly shortens the preparation time and improves the construction efficiency.

[0027] Second embodiment:

[0028] like Figure 3 As shown, the groove at one end of the positioning groove 303 is the same size as the diameter of the crossbeam 400, and the crossbeam 400 is fitted into the groove of the positioning groove 303.

[0029] The groove at one end of the positioning slot 303 has the same diameter as the crossbeam 400, and the crossbeam 400 fits into the groove of the positioning slot 303. This makes the assembly process faster and reduces the time required for precise adjustment of the component position. Operators only need to align the crossbeam 400 with the groove to achieve quick assembly, which reduces the requirements for operating skills. At the same time, the tight fit between the crossbeam 400 and the groove reduces the relative movement between them, thereby improving the overall stability of the guardrail.

[0030] Third embodiment:

[0031] like Figures 2-4 As shown, a limiting component 200 is also sleeved in the limiting cavity 103 of the protective beam 101. The limiting component 200 includes a positioning rod 201. A limiting plate 202 is symmetrically arranged at the bottom of the positioning rod 201. The positioning rod 201 is sleeved in the limiting cavity 103 of the protective beam 101.

[0032] By using multiple parts within the limiting assembly 200, the positioning rod 201 is fitted into the limiting cavity 103 of the protective beam 101. In conjunction with the positioning beam 301 and the crossbeam 400, in actual use, the positioning beam 301 is simply fitted into the positioning rod 201. The tight fit between the positioning rod 201 and the positioning beam 301 ensures the stability of the positioning beam 301 and the overall weight of the positioning beam 301 and the protective beam 101.

[0033] Fourth embodiment:

[0034] like Figures 2-4 As shown, the base 102 at the bottom of the protective beam 101 has slots 104 on both sides, and the positioning rod 201 is sleeved inside the protective beam 101, and the limiting plate 202 of the positioning rod 201 is engaged with the slots 104 at the bottom of the protective beam 101.

[0035] The base 102 has slots 104 on both sides that cooperate with the positioning rod 201 and the limiting plate 202. The slots 104 and the limiting plate 202 of the positioning rod 201 are fitted together, so that the positioning rod 201 is fixedly limited within the limiting cavity 103 of the protective beam 101, ensuring the tightness of the overall installation.

[0036] Fifth embodiment:

[0037] like Figures 3-4 As shown, the positioning beam 301 has a through groove 302, which is adapted to the positioning rod 201, and the positioning beam 301 is fitted into the positioning rod 201 inside the limiting cavity 103.

[0038] The positioning beam 301 has a through groove 302 that is adapted to the positioning rod 201. When the positioning beam 301 is fitted onto the positioning rod 201, the positioning beam 301 is simultaneously fitted with the limiting cavity 103 of the protective beam 101. The cooperation between the positioning beam 301 and the positioning rod 201 can ensure the stability of the structure and prevent displacement or deformation under the influence of force or other external factors.

[0039] Sixth embodiment:

[0040] like Figure 3 As shown, a rubber ring 500 is also fitted on the crossbeam 400, and the rubber ring 500 wraps around the crossbeam 400.

[0041] The rubber ring 500 has good elasticity and can absorb and buffer the vibration of the crossbeam 400 caused by external forces, thereby protecting the stability of the entire guardrail.

[0042] Working principle: In actual use, the operator places the positioning rod 201 vertically, then places the protective beam 101 around the positioning rod 201. After placement, the operator places the positioning beam 301 inside the positioning rod 201. At this time, the limiting cavity 103 of the protective beam 101, the positioning rod 201, and the positioning beam 301 fit tightly together. After the positioning beam 301 is installed, the operator aligns the multiple crossbeams 400 with the positioning grooves 303 at both ends of the positioning beam 301, and then fixes it with the pre-tightening bolts 304.

[0043] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
