Abstract
Description
Technical Field
[0001] This utility model relates to the field of guardrail technology, and in particular to a guardrail for road and bridge construction. Background Technology
[0002] In the field of road and bridge construction, guardrails are key facilities for ensuring construction safety and demarcating areas. However, traditional road and bridge guardrails have significant shortcomings in terms of their telescopic function.
[0003] Most existing guardrails are designed with fixed lengths and widths. During construction, due to the complexity and diversity of road and bridge construction sites, the required isolation range varies from section to section. When construction areas are adjusted, such as road widening or temporary increases or decreases in construction area, fixed-size guardrails cannot flexibly adapt to new boundary requirements. For some large-scale, phased road and bridge projects, it may be necessary to repeatedly dismantle and reinstall guardrails to meet the isolation needs of different construction stages. This not only consumes a lot of manpower, resources, and time, but frequent dismantling and reinstallation can also damage guardrail components, reducing their service life. Furthermore, traditional guardrails lack effective telescopic structures, making it difficult to easily adjust length and width, limiting their application in various complex road and bridge construction scenarios, increasing construction costs and management difficulty, and negatively impacting construction progress and safety. Therefore, improvements are needed to address these issues. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example: See Figure 1 This utility model discloses a road and bridge construction guardrail, comprising a main post 1 and an auxiliary post 4. The main post 1 and the auxiliary post 4 have fixing holes around their bottom edges for ground mounting. Multiple sets of scissor braces 5 are installed between the main post 1 and the auxiliary post 4, and a retractable guardrail is installed between them. A nighttime lighting system is installed on the main post 1, and a water-proof hook 11 is installed on the auxiliary post 4. The guardrail is easily fixed to the ground through the fixing holes at the bottom of the main post 1 and the auxiliary post 4. The retractable guardrail includes an upper fixing rod 2 fixed to the upper part of the main post 1 and a lower fixing rod 7 installed at the lower part of the main post 1. A storage groove is provided at the other end of both the upper fixing rod 2 and the lower fixing rod 7, and a connecting component is installed in the storage groove. Both the upper fixing rod 2 and the lower fixing rod 7 are bolted to one side of the main post 1. The bottom surface of the upper fixed rod 2 and the top surface of the lower fixed rod 7 are both provided with grooves for fixing the scissor brace 5. The upper fixed rod 2 and the lower fixed rod 7 are installed on the main column 1, and the grooves and bolts are provided to facilitate cooperation with the telescopic rod to realize the telescopic function. The connecting component includes an upper telescopic rod 3 installed at one end of the upper fixed rod 2 and a lower telescopic rod 6 installed at one end of the lower fixed rod 7. The front end face of the upper telescopic rod 3 and the lower telescopic rod 6 are provided with a sliding groove in the middle. The upper telescopic rod 3 and the lower telescopic rod 6 can be retracted inside the upper fixed rod 2 and the lower fixed rod 7. The other end of the upper telescopic rod 3 and the lower telescopic rod 6 are fixed to the auxiliary column 4 by bolts. The through grooves on the upper telescopic rod 3 and the lower telescopic rod 6 cooperate with the bolts on the fixed rod and are connected to the main column 1 and the auxiliary column 4 to facilitate the telescopic function of the railing and change the width of the isolation fence.
[0020] In this invention, both the upper fixed rod 2 and the lower fixed rod 7 have positioning bolts installed at one end in a sliding groove. One end of the positioning bolt is movably inserted into the sliding groove, allowing for lateral movement through the engagement of the groove on the telescopic rod with the fixing bolt. This facilitates flexible adjustment of the telescopic rod's position, thereby adjusting the width of the barrier. The bottom of the upper telescopic rod 3 and the top of the lower telescopic rod 6 are both provided with limiting slots for fixing the scissor brace 5. By installing the scissor brace 5 between the upper and lower telescopic railings and bolting it to the main post 1 and auxiliary post 4, the size of the barrier can be easily adjusted in the length direction. Nighttime lighting... The system includes an LED light 9 mounted on a main column 1. The lower front end of the main column 1 has a mounting cavity containing a battery 12. A protective plate 8 is bolted into the front opening of the mounting cavity. The LED light 9 is electrically connected to the battery 12 via wires. An inclined solar panel 10 is mounted on the upper rear end of the main column 1. The solar panel 10 is electrically connected to the battery 12 via wires. Through the cooperation of the LED light 9, the battery 12, and the solar panel 10, it is easy to use solar energy to power the lighting system and achieve nighttime lighting.
[0021] Working Principle: In use, the telescopic guardrail consists of an upper fixed rod 2, a lower fixed rod 7, an upper telescopic rod 3, and a lower telescopic rod 6. The upper fixed rod 2 and the lower fixed rod 7 are installed on one side of the main post 1, and both have grooves and bolts. The upper telescopic rod 3 and the lower telescopic rod 6 have transverse through grooves, through which they are installed on the bolts of the upper fixed rod 2 and the lower fixed rod 7. The other side of the upper telescopic rod 3 and the lower telescopic rod 6 are installed on the auxiliary post 4. When the width of the guardrail needs to be adjusted, the upper telescopic rod 3 and the lower telescopic rod 6 can move within the range of the transverse through grooves along the bolts on the upper fixed rod 2 and the lower fixed rod 7. This design allows the width of the guardrail to be flexibly changed according to actual needs to adapt to different construction site width requirements. The scissor brace 5 is installed between the upper and lower telescopic guardrails, and its two ends are bolted to the main post 1 and the auxiliary post 4. The structural characteristics of the scissor brace 5 allow it to be stretched or adjusted. The length of the guardrail changes when compressed. When the length of the guardrail needs to be adjusted, the extension or retraction of the scissor brace 5 is adjusted to change the length of the guardrail, thereby meeting the length requirements of different construction areas. A solar panel 10 is installed at the rear end of the main column 1. Under daylight conditions, the solar panel 10 converts solar energy into electrical energy and stores the electrical energy in the battery 12 installed at the bottom of the main column 1. The battery 12 powers the LED light 9 installed on the main column 1. When the LED light 9 is lit, it provides lighting for the road and bridge construction site, ensuring that construction workers can see the guardrails set up around them at night, ensuring construction safety and normal progress. The auxiliary column 4 is equipped with a water-proof protective gear hook 11. Construction workers can hang water-proof protective gear such as lifebuoys on the hook. In the process of road and bridge construction near water, in case of an accident, construction workers can quickly obtain water-proof protective gear to reduce the danger of falling into the water.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
