Description

Technical Field

[0001] This utility model relates to the field of road construction safety early warning technology, and in particular to a road construction safety early warning vehicle. Background Technology

[0002] Road engineering refers to the entire process of planning, designing, constructing, maintaining, and managing roads, as well as the engineering entities involved. Like any other type of civil engineering, road engineering has distinct technical, economic, and managerial characteristics. Roads arise alongside human activities and promote social progress and development; they are a symbol of historical civilization and a sign of scientific advancement. Currently, during road construction, it is necessary to use warning vehicles to alert pedestrians and vehicles to pay attention to safety.

[0003] During road construction, if vehicles do not receive advance warning of the construction, they may not be able to detect the construction ahead in time and may directly enter the work area, resulting in collisions and injuries to construction workers. The probability of accidents is doubled, especially in environments with poor visibility such as night, heavy rain, and dense fog. To address the above issues, the following solutions are proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a road construction safety early warning vehicle to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road construction safety early warning vehicle, including a main body, the main body also including an early warning mechanism, a number of movable wheels are provided at the bottom of the main body, a shell is fixedly connected to the side of the main body away from the movable wheels, and an early warning light is fixedly connected to the side of the shell away from the main body.

[0006] Preferably, an electric telescopic rod is fixedly connected to the top inner wall of the housing, a push plate is fixedly connected to the end of the electric telescopic rod away from the housing, and a fixing block is fixedly connected to the bottom inner wall of the housing.

[0007] Preferably, a push rod is fixedly connected to the side of the push plate away from the electric telescopic rod, the push rod extends into the fixed block and is slidably connected to the fixed block, and a connecting block is fixedly connected to the side wall of the fixed block.

[0008] Preferably, a connecting strip is fixedly connected to the outer wall of the push rod, and a hinged guardrail is rotatably connected to the side of the connecting strip away from the push rod. The side of the hinged guardrail away from the connecting strip is rotatably connected to the connecting block.

[0009] Preferably, the outer wall of the hinged guardrail is fixedly connected with several hazard alarm flashing lights, the outer wall of the shell is fixedly connected with a connecting rod, and a brush is fixedly connected to the end of the connecting rod away from the shell.

[0010] Preferably, the fixed block has a movable groove, and an airbag is fixedly connected to the bottom inner wall of the movable groove. The top of the airbag is fixedly connected to the push rod.

[0011] Preferably, an air supply pipe is fixedly connected to the outer wall of the airbag, and the end of the air supply pipe away from the airbag extends to the outside of the fixing block and is fixedly connected to the fixing block.

[0012] Preferably, an air guide cover is fixedly connected to the end of the air supply pipe away from the airbag.

[0013] The beneficial effects of this utility model are as follows: In this utility model: When the warning vehicle is needed, it is first placed in the designated location, and then the electric telescopic boom is activated. The electric telescopic boom moves the push plate downward, which in turn moves the push rod downward, causing the connecting strip to move downward simultaneously. This expands the articulated guardrail outward to the preset position, accurately covering the danger zone of the construction area and avoiding gaps in protection due to manual placement errors. This allows vehicles behind to clearly identify the safety boundary. When the warning vehicle needs to be moved, the electric telescopic boom can retract in the opposite direction, automatically retracting the articulated guardrail without manual disassembly. This facilitates the rapid relocation of the warning vehicle to a new construction location and adapts to the needs of multi-location operations. After the articulated guardrail is expanded, it is equipped with hazard warning flashers. These flashing lights, with their high brightness, can warn vehicles behind of the construction area from hundreds of meters away, giving drivers sufficient time to slow down and change lanes, avoiding sudden braking or failure to avoid the danger due to late detection. This solves the efficiency and error problems of manual operation and enhances the early warning effect for vehicles behind, comprehensively improving the safety protection of the construction area.

[0014] When the electric telescopic pole extends or retracts the articulated guardrail, the hazard warning lights on the guardrail come into contact with the brush. In dusty construction areas, the surface of the hazard warning lights easily accumulates dust, which can obstruct the light and reduce brightness, making it difficult for following vehicles to see them from a distance. The brush, through its linkage with the hazard warning lights, automatically wipes away the surface dust when the guardrail extends or retracts, ensuring that the hazard warning lights maintain high transparency and remain clear and bright. This allows following vehicles to detect the construction area earlier and more accurately, reducing the risk of accidents caused by dust accumulation. The lack of clear warnings can lead to accidents such as vehicles running over or rear-ending each other, indirectly protecting the safety of construction workers and equipment and reducing economic losses caused by accidents. When the electric telescopic rod moves the push rod downward, the push rod applies pressure to the airbag. After the airbag is compressed, the internal gas is blown towards the brush through the air supply pipe and air guide cover. The airbag can blow away the dust adsorbed by the brush when wiping the surface of the hazard warning flasher, preventing dust from accumulating on the brush. This allows the brush to maintain a good cleaning ability, thereby more effectively ensuring the cleanliness of the hazard warning flasher and ensuring its warning effect.

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.

[0018] This utility model provides, for example Figure 1-5The road construction safety early warning vehicle shown includes a main body 101, which also includes an early warning mechanism 1. Several movable wheels 102 are provided at the bottom of the main body 101. A housing 103 is fixedly connected to the side of the main body 101 away from the movable wheels 102. A warning light 104 is fixedly connected to the side of the housing 103 away from the main body 101. An electric telescopic rod 105 is fixedly connected to the inner top wall of the housing 103. A push plate 106 is fixedly connected to the end of the electric telescopic rod 105 away from the housing 103. A fixing block 107 is fixedly connected to the inner bottom wall of the housing 103. A push plate 106 is fixedly connected to the side of the push plate 106 away from the electric telescopic rod 105. A rod 108 extends into a fixed block 107 and is slidably connected to the fixed block 107. A connecting block 109 is fixedly connected to the side wall of the fixed block 107. A connecting strip 110 is fixedly connected to the outer wall of the push rod 108. A hinged guardrail 111 is rotatably connected to the side of the connecting strip 110 away from the push rod 108. The side of the hinged guardrail 111 away from the connecting strip 110 is rotatably connected to the connecting block 109. Several hazard alarm flashing lights 112 are fixedly connected to the outer wall of the hinged guardrail 111. A connecting rod 113 is fixedly connected to the outer wall of the housing 103. A brush 114 is fixedly connected to the end of the connecting rod 113 away from the housing 103. When the warning vehicle is needed, it is first placed in the designated location, and then the electric telescopic pole 105 is activated. The electric telescopic pole 105 drives the push plate 106 to move downwards. During the downward movement of the push plate 106, the push rod 108 moves downwards, and during the downward movement of the push rod 108, the connecting strip 110 moves downwards simultaneously, thereby causing the articulated guardrail 111 to expand outwards to the preset position. This accurately covers the dangerous area of ​​the construction zone, avoiding protective gaps caused by manual placement errors, and allowing vehicles behind to clearly identify the safety boundary. When the warning vehicle needs to be moved, the electric telescopic pole 105 can retract in the opposite direction. The articulated guardrail 111 retracts automatically without manual disassembly, facilitating the rapid relocation of the warning vehicle to a new construction location. It adapts to the needs of multi-location operations. After the articulated guardrail 111 is extended, it is equipped with hazard warning flashers 112. The hazard warning flashers 112 use high-brightness flashing lights to warn vehicles behind of the construction area ahead from hundreds of meters away, giving drivers enough time to slow down and change lanes, avoiding sudden braking or failure to avoid the situation due to late detection. This solves the efficiency and error problems of manual operation, enhances the early warning effect for vehicles behind, and comprehensively improves the safety protection of the construction area.

[0019] The fixed block 107 has a movable groove 115. An airbag 116 is fixedly connected to the bottom inner wall of the movable groove 115. The top of the airbag 116 is fixedly connected to the push rod 108. An air supply pipe 117 is fixedly connected to the outer wall of the airbag 116. One end of the air supply pipe 117 away from the airbag 116 extends to the outside of the fixed block 107 and is fixedly connected to the fixed block 107. An air guide cover 118 is fixedly connected to the other end of the air supply pipe 117 away from the airbag 116. When the electric telescopic pole 105 extends or retracts the articulated guardrail 111, the hazard warning flashers 112 on the articulated guardrail 111 will come into contact with the brush 114. In dusty construction areas, the surface of the hazard warning flashers 112 easily accumulates dust, which can obstruct the light and reduce brightness, making it difficult for following vehicles to see them from a distance. The brush 114, through its linkage with the hazard warning flashers 112, automatically wipes away surface dust when the guardrail extends or retracts, ensuring that the hazard warning flashers 112 always maintain high transparency and remain clear and bright. This allows following vehicles to detect the construction area earlier and more accurately, reducing accidents caused by unclear warnings. In case of accidents such as vehicle intrusion or rear-end collisions, the electric telescopic pole 105 indirectly protects the safety of construction personnel and equipment and reduces economic losses caused by accidents. When the electric telescopic pole 105 drives the push rod 108 to move downward, the push rod 108 applies pressure to the airbag 116. After the airbag 116 is compressed, the internal gas will be blown towards the brush 114 through the air supply pipe 117 and the air guide cover 118. The airbag 116 can blow away the dust adsorbed by the brush 114 when wiping the surface of the hazard warning flash light 112, preventing dust from accumulating on the brush 114, so that the brush 114 can maintain a good cleaning ability, thereby more effectively ensuring the cleanliness of the hazard warning flash light 112 and ensuring its warning effect.

[0020] The working principle of the road construction safety early warning vehicle provided by this utility model is as follows: When the early warning vehicle is needed, it is first placed in a designated position, and then the electric telescopic pole 105 is activated. The electric telescopic pole 105 drives the push plate 106 to move downward. During the downward movement of the push plate 106, the push rod 108 moves downward. During the downward movement of the push rod 108, the connecting strip 110 moves downward simultaneously, thereby causing the articulated guardrail 111 to expand outward to the preset position. This can accurately cover the dangerous area of ​​the construction area, avoid protective gaps caused by manual placement deviations, and allow vehicles behind to clearly identify the safety boundary. When the early warning vehicle needs to be moved, the electric telescopic pole 105 is activated. The telescopic pole 105 can retract in the opposite direction, causing the articulated guardrail 111 to automatically retract without manual disassembly. This allows the warning vehicle to quickly move to a new construction location, adapting to the needs of multi-location operations. After the articulated guardrail 111 is extended, it is equipped with a hazard warning flashing light 112. The hazard warning flashing light 112 can warn vehicles behind of the construction area from hundreds of meters away, giving drivers enough time to slow down and change lanes, avoiding sudden braking or failure to avoid due to late detection. This solves the efficiency and error problems of manual operation, and enhances the early warning effect for vehicles behind, comprehensively improving the safety protection of the construction area. When the electric telescopic pole 105 extends or retracts the articulated guardrail 111, the hazard warning flashers 112 on the articulated guardrail 111 will come into contact with the brush 114. In dusty construction areas, the surface of the hazard warning flashers 112 easily accumulates dust, which can obstruct the light and reduce brightness, making it difficult for following vehicles to see them from a distance. The brush 114, through its linkage with the hazard warning flashers 112, automatically wipes away surface dust when the guardrail extends or retracts, ensuring that the hazard warning flashers 112 always maintain high transparency and remain clear and bright. This allows following vehicles to detect the construction area earlier and more accurately, reducing accidents caused by unclear warnings. In case of accidents such as vehicle intrusion or rear-end collisions, the electric telescopic pole 105 indirectly protects the safety of construction personnel and equipment and reduces economic losses caused by accidents. When the electric telescopic pole 105 drives the push rod 108 to move downward, the push rod 108 applies pressure to the airbag 116. After the airbag 116 is compressed, the internal gas will be blown towards the brush 114 through the air supply pipe 117 and the air guide cover 118. The airbag 116 can blow away the dust adsorbed by the brush 114 when wiping the surface of the hazard warning flash light 112, preventing dust from accumulating on the brush 114, so that the brush 114 can maintain a good cleaning ability, thereby more effectively ensuring the cleanliness of the hazard warning flash light 112 and ensuring its warning effect.

[0021] Compared with related technologies, the road construction safety early warning vehicle provided by this utility model has the following beneficial effects: This utility model provides a road construction safety early warning vehicle. When the vehicle is needed, it is first placed in a designated location, and then the electric telescopic pole 105 is activated.

This accurately covers the dangerous area of ​​the construction zone, avoiding protective gaps caused by manual placement errors, and allowing vehicles behind to clearly identify the safety boundary. When the early warning vehicle needs to be moved, the electric telescopic pole... 105 can be retracted in the opposite direction, causing the articulated guardrail 111 to retract automatically without manual disassembly, facilitating the rapid transfer of the warning vehicle to a new construction location and adapting to the needs of multi-location operations. After the articulated guardrail 111 is extended, it is equipped with a hazard warning flashing light 112. The hazard warning flashing light 112 can warn vehicles behind of the construction area from hundreds of meters away with its high-brightness flashing light, giving drivers enough time to slow down and change lanes, avoiding sudden braking or failure to avoid due to late detection. This solves the efficiency and deviation problems of manual operation, and enhances the early warning effect for vehicles behind, comprehensively improving the safety protection of the construction area. When the electric telescopic pole 105 extends or retracts the articulated guardrail 111, the hazard warning flashers 112 on the articulated guardrail 111 will come into contact with the brush 114. In dusty construction areas, the surface of the hazard warning flashers 112 easily accumulates dust, which can obstruct the light and reduce brightness, making it difficult for following vehicles to see them from a distance. The brush 114, through its linkage with the hazard warning flashers 112, automatically wipes away surface dust when the guardrail extends or retracts, ensuring that the hazard warning flashers 112 always maintain high transparency and remain clear and bright. This allows following vehicles to detect the construction area earlier and more accurately, reducing accidents caused by unclear warnings.
