Description

Technical Field

[0001] This utility model relates to the technical field of road construction protection equipment, specifically to temporary protective barriers for road repair. Background Technology

[0002] During road repair construction, temporary guardrails are typically installed to ensure safety in the construction area and guide vehicles and pedestrians to pass in an orderly manner. Currently, most temporary guardrails used for road repair are fixed structures, which have the following shortcomings: First, they are inconvenient to transport. Fixed guardrails occupy a large amount of space, and the number transported at one time is limited, increasing transportation costs and difficulties. Second, installation and dismantling are inefficient. Multiple people are needed to assemble and dismantle them using tools, consuming a lot of manpower and time, making it difficult to meet the needs of frequently moving protected areas during road repair construction. Third, the warning effect is poor. Some guardrails rely solely on their color for warning, which results in short warning distances and low visibility at night or in severe weather conditions (such as heavy rain or fog), easily leading to traffic accidents. To address the problems existing in the prior art, this utility model proposes a temporary guardrail for road repair, which improves transportation convenience, installation and dismantling efficiency, and warning effect.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4The present invention provides a technical solution: a temporary guardrail for road repair, comprising a guardrail body 1, a folding mechanism 2, a warning mechanism 3 and a stabilizing mechanism 4. The guardrail body 1 is composed of multiple sets of protective units 11 spliced ​​together. Adjacent sets of protective units 11 are connected by the folding mechanism 2. The warning mechanism 3 is installed on the top of the guardrail body 1, and the stabilizing mechanism 4 is set at the bottom of the guardrail body 1.

[0020] The protective unit 11 includes horizontal bars and vertical bars. The horizontal bars are divided into upper and lower sets, and several vertical bars are evenly distributed between the two sets of horizontal bars. The two ends of the vertical bars are welded and fixed to the upper and lower sets of horizontal bars respectively. Both the horizontal bars and vertical bars are made of 6061 aluminum alloy, which has the characteristics of high strength and lightweight. It can not only ensure the protective strength of the guardrail, but also reduce the overall weight, making it easy to transport and handle.

[0021] The folding mechanism 2 includes a hinge 21, a pin hole 22, and a locking pin. The two flaps of the hinge 21 are respectively bolted to the crossbars of two adjacent sets of protective units 11, allowing the two sets of protective units 11 to rotate around the hinge 21. Pin holes 22 are provided at the ends of the crossbars. When the guardrail is unfolded to the working state, the locking pin is inserted into the pin holes 22 of the crossbars of the two adjacent sets of protective units 11, thus securing the adjacent protective units 11. During transportation, the locking pin is pulled out, and the protective units 11 are rotated around the hinge 21 to fold the adjacent protective units 11 together, reducing space occupation. Upon arrival at the construction site, the protective units 11 are unfolded, and the locking pin is inserted to complete assembly; the operation is simple and quick.

[0022] The warning mechanism 3 includes a warning light 31, a solar panel 32, a locking bolt 33, and a battery 34. The warning light 31 is evenly installed on the top horizontal bar of the guardrail body 1. The warning light 31 is an LED flashing light, and its color is red. The flashing frequency can be adjusted by a controller, with an adjustment range of 1-5 times / second. The solar panel 32 is movably mounted on the top horizontal bar of the guardrail body 1. The solar panel 32 is positioned on the top horizontal bar of the guardrail body 1 by the locking bolt 33, which enables the solar panel 32 to be angled. The angle of the solar panel 32 is adjustable to facilitate solar power generation at a suitable angle, and also to facilitate the storage of the solar panel 32 when the guardrail is folded up. The battery 34 is installed on the crossbar at the bottom of the guardrail body 1. The solar panel 32 is a 18V / 10W model; the battery 34 is a 12V / 20Ah lead-acid battery. The solar panel 32 and the battery 34 are electrically connected by wires, and the wires are covered with protective tubes to prevent damage during construction. The battery 34 is electrically connected to the warning light 31 by wires, providing power to the warning light 31. During the day, the solar panel 32 converts solar energy into electrical energy and stores it in the battery 34. At night or when there is insufficient light, the battery 34 powers the warning light 31, causing the warning light 31 to flash, serving as a warning.

[0023] The stabilizing mechanism 4 includes a counterweight 41, a fixed insert rod 42, a connector 43, and a second locking bolt 44. The counterweight 41 is made of concrete. Depending on the wind conditions and ground conditions at the construction site, different numbers of counterweights 41 can be installed. The fixed insert rod 42 is fixed on the counterweight 41. The connector 43 is fixed to the bottom of the guardrail body 1. The fixed insert rod 42 is inserted through the connector 43. The lower end of the connector 43 is threaded with a second locking bolt 44. The front end of the second locking bolt 44 abuts against the fixed insert rod 42. This allows the counterweight 41 to be fixedly connected to the connector 43 on different ground elevations through the fixed insert rod 42. This facilitates the horizontal support and fixation of the guardrail body 1 on different ground elevations, ensuring the stability of the protective work. The counterweight 41 weighs 5kg and has mounting holes. It is connected to the fixing rod 42 via bolts, allowing for quick assembly and disassembly of the counterweight 41 and fixing rod 42, facilitating the replacement of the fixing rod 42. During installation, the guardrail is first placed in the designated location. Then, the fixing rod 42 is inserted into the connector 43, and the connection between the connector 43 and the fixing rod 42 is secured using locking bolts 44, thus fixing the guardrail in place.

[0024] The surface of the guardrail body 1 is coated with a reflective coating, which is a high refractive index glass microsphere reflective paint with a coating thickness of 0.1-0.2mm. This reflective coating can produce a strong reflective effect under light, and can provide clear warning signs for passing vehicles and pedestrians even when the warning light 31 is not turned on.

[0025] Specifically, when using this temporary road repair guardrail, the guardrail in its folded state is first transported to the road repair construction site. Then, the guardrail unit 11 is unfolded around the hinge 21, and the adjacent guardrail units 11 are fixed by inserting locking pins into the pin holes 22. Next, according to the construction site conditions, the counterweight block 41 is installed and placed at the corresponding position of the plug-in seat 43 on the guardrail body 1, so that the fixing rod 42 is inserted into the plug-in seat 43, and the locking bolt 44 is rotated to fix the fixing rod 42 to the plug-in seat 43. If the ground is uneven, after the counterweight block 41 is placed stably on the ground, the fixing rod 42 can slide up and down in the plug-in seat 43 to ensure that the guardrail body 1 is level, thus completing the fixed installation of the guardrail. Finally, the switch of the warning light 31 is turned on, and the warning light 31 begins to flash. At the same time, the reflective coating on the surface of the guardrail reflects light under the illumination, which together serve as a warning. When the protected area needs to be moved, simply pull out the locking pin, remove the counterweight 41, and fold the guardrail for transport. It is easy to operate and highly practical.

[0026] Although the present invention 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
