Description

Technical Field

[0001] This invention belongs to the field of road construction technology, specifically referring to a protective device for construction workers used in highway construction. Background Technology

[0002] As a key component of modern transportation networks, highways play an irreplaceable role in promoting regional economic prosperity and improving transportation efficiency. During highway construction, construction workers serve as the core force in the project, and their safety and health are directly linked to the smooth progress and quality assurance of the project. Given the complexity of the construction environment and various potential risks during construction, construction workers face numerous safety threats. Therefore, providing scientific and effective protection for highway construction workers is not only crucial for safeguarding their basic rights but also an essential prerequisite for ensuring the high-quality and efficient completion of highway construction projects, making it of paramount importance.

[0003] Existing guardrails typically provide protection by simply fixing a single layer of guardrail to the road section, resulting in poor protection. Furthermore, most guardrails are assembled using a plug-in method for easy disassembly and reassembly, but guardrails assembled in this way are generally not sturdy and require improvement. Additionally, existing protective facilities in construction areas are relatively basic, mainly serving as warnings to passing vehicles. Construction workers are mostly in a passive defensive situation; if they encounter an out-of-control vehicle, they have little time to prepare for defense or avoid it. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a construction worker protection device for highway road construction, so as to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this invention is as follows: This invention provides a construction worker protection device for highway road construction, including a road barrier base, a remote warning unit, and a cavity buffer unit. The remote warning unit is located on one side of the road barrier base and is used to actively purify the air in the construction area and warn oncoming vehicles from a distance, thereby improving the safety of the construction environment and the visibility warning effect. The cavity buffer unit is located on the other side of the road barrier base and is used to absorb impact energy through a multi-stage buffering and forced deceleration mechanism when a vehicle accidentally enters the road, thereby maximizing the protection of construction workers' safety.

[0006] Furthermore, the remote warning unit includes an axial flow fan, an acceleration channel, a dust removal channel, and a water mist sprayer. The dust removal channel is located on one side of the roadblock base. The acceleration channel is connected to the side wall of the dust removal channel, using the wall-attachment effect to accelerate the airflow and form a negative pressure zone at the entrance of the dust removal channel, actively sucking up the dust-laden air in the construction area. The axial flow fan is connected to the top of the acceleration channel, and the water mist sprayer is located at the top of the dust removal channel.

[0007] Furthermore, the dust removal channel is equipped with a separation dust removal system, which consists of multiple sets of inertial baffles. By changing the airflow direction, the dust particles are separated from the airflow by their inertia. After impacting the baffles, the particles fall, thus achieving preliminary dust removal. The bottom of the dust removal channel is equipped with a dust discharge outlet.

[0008] Furthermore, the water mist sprayer is equipped with a spotlight to provide a light source. When the light passes through the water mist, it generates the Tyndall effect, forming a conspicuous beam of light for long-distance warning. The top of the water mist sprayer is equipped with a spray ring, and a water pump is fixedly connected to the outside of the water mist sprayer. The water outlet of the water pump is connected to the spray ring.

[0009] Furthermore, the cavity buffer unit includes a buffer chamber, a telescopic buffer, and a deceleration mounting system. The buffer chamber is slidably disposed on the other side of the roadblock base, serving as the main buffer body. It contains an air cushion and provides rear support during impact. The telescopic buffer is fixedly connected to the side wall of the buffer chamber, and the deceleration mounting system is disposed on the side wall of the buffer chamber.

[0010] Furthermore, the telescopic buffer consists of multiple slidingly connected buffer chambers, with a pressure cavity in the middle of each buffer chamber. The pressure cavities of adjacent buffer chambers are slidably connected, and reflective warning strips are slidably connected to the side walls of the outer buffer chambers. A front-end base is provided at the bottom of the outer buffer chambers.

[0011] Furthermore, the deceleration mounting system includes a deceleration shaft, a deceleration belt, and a storage wheel. The deceleration shaft is rotatably connected to the buffer chamber, the deceleration belt is wound around the deceleration shaft, and the storage wheel is fixedly connected to the deceleration shaft for winding and storing the deceleration belt when not in use or during recycling.

[0012] Furthermore, the end of the speed bump is connected to a speed reduction groove, and the bottom of the front base is provided with a bottom bracket, which engages with the speed reduction groove.

[0013] Furthermore, the buffer chamber is equipped with an air cushion, which expands upon inflation to provide a soft impact buffer layer, absorbing residual impact energy and protecting construction personnel. The air cushion is connected to a pressure cavity, so that when the telescopic buffer is compressed by impact, the high-pressure gas generated in the pressure cavity can quickly replenish the air cushion, enhancing its cushioning capacity. A small air compressor is installed above the roadblock base, and the outlet of the small air compressor is connected to the air inlet of the air cushion. When the telescopic buffer is compressed by impact, the high-pressure gas generated in the pressure cavity can quickly replenish the air cushion, enhancing its cushioning capacity.

[0014] As a further preferred embodiment of the present invention, the speed bump is filled with a non-Newtonian fluid, which makes the speed bump relatively soft (low resistance) when the vehicle runs over it at low speed, and hardens instantly (high resistance) when impacted at high speed, generating huge resistance to force the high-speed vehicle to decelerate quickly, thus significantly improving the interception effect.

[0015] The beneficial effects of the construction worker protection device for highway road construction provided in this solution are as follows: (1) Through the synergistic effect of axial flow fan, acceleration channel and dust removal channel (built-in inertial baffle separation dust removal system), it can actively suck up dust-laden air in the construction area and perform inertial separation dust removal, effectively reducing the dust concentration in the construction area and protecting the respiratory health of construction personnel; (2) The water mist sprayer sprays water mist, which, combined with the spotlight source, forms a clear and bright beam of light using the Tyndall effect. Especially at night or in low visibility conditions such as fog and haze, it can warn oncoming vehicles from a distance and attract the driver's attention in advance. (3) A cavity buffer unit is set up. The telescopic buffer, which is composed of multiple sliding buffer chambers, can effectively absorb the impact kinetic energy by gradually contracting and sliding when hit by a vehicle. At the same time, the air cushion in the buffer chamber is connected to the pressure cavity. The air cushion can be inflated and expanded to provide an additional collision buffer layer. The speed bump filled with non-Newtonian fluid is soft when the vehicle runs over it at low speed and hardens when it impacts at high speed, generating huge resistance, effectively consuming the vehicle's kinetic energy and forcing it to slow down and stop.

[0021] like Figures 1-9 As shown, the present invention provides a construction worker protection device for highway road construction, including a road barrier base 1, a remote warning unit 2 and a cavity buffer unit 3. The remote warning unit 2 is located on one side of the road barrier base 1, and the cavity buffer unit 3 is located on the other side of the road barrier base 1.

[0022] The remote warning unit 2 includes an axial flow fan 201, an acceleration channel 202, a dust removal channel 203, and a water mist sprayer 204. The dust removal channel 203 is located on one side of the roadblock base 1. The acceleration channel 202 is connected to the side wall of the dust removal channel 203. The axial flow fan 201 is connected to the top of the acceleration channel 202. The water mist sprayer 204 is located at the top of the dust removal channel 203. The dust removal channel 203 is equipped with a separation dust removal system 205, which consists of multiple sets of inertial baffles 209. The bottom of the dust removal channel 203 is equipped with a dust discharge outlet 210. The water mist sprayer 204 is equipped with a spotlight 207. The top of the water mist sprayer 204 is equipped with a spray ring 208. A water pump 206 is fixed to the outside of the water mist sprayer 204. The water outlet of the water pump 206 is connected to the spray ring 208.

[0023] The cavity buffer unit 3 includes a buffer chamber 301, a telescopic buffer 302, and a deceleration mounting system 303. The buffer chamber 301 is slidably disposed on the other side of the road barrier base 1. The telescopic buffer 302 is fixedly connected to the side wall of the buffer chamber 301. The deceleration mounting system 303 is disposed on the side wall of the buffer chamber 301. The telescopic buffer 302 is composed of multiple slidably connected buffer sleeves 304. A pressure cavity 307 is provided in the middle of the buffer sleeve 304. The pressure cavities 307 of adjacent buffer sleeves 304 are slidably connected. A reflective warning strip 305 is slidably connected to the side wall of the outer buffer sleeve 304. A front end base 306 is provided at the bottom of the outer buffer sleeve 304. The carrying system 303 includes a reduction shaft 308, a reduction belt 309, and a receiving wheel 310. The reduction shaft 308 is rotatably connected to the buffer chamber 301. The reduction belt 309 is wound around the reduction shaft 308. The receiving wheel 310 is fixedly connected to the reduction shaft 308. The end of the reduction belt 309 is connected to a reduction groove 311. The bottom of the front base 306 is provided with a bottom seat 312, which is engaged with the reduction groove 311. An air cushion 313 is provided inside the buffer chamber 301. The air cushion 313 is connected to the pressure cavity 307. A small air compressor 314 is provided above the roadblock base 1. The air outlet of the small air compressor 314 is connected to the air inlet of the air cushion 313.

[0024] In practical use, the device is installed in front of the lane corresponding to the construction area. The axial flow fan 201 is started, drawing air in from above and sending it into the acceleration channel 202. Guided by the inner wall of the acceleration channel 202, the air exits from the inner outlet. The inner wall of the acceleration channel 202 forms a wall-attached airflow that blows into the dust removal channel 203. Due to the increased airflow velocity and decreased pressure within the acceleration channel 202, air is drawn in from the outside at the outer end of the acceleration channel 202. At this time, dust-laden air in the construction area is drawn into the dust removal channel 203 through the acceleration channel 202. After entering the dust removal channel 203, the dust-laden air undergoes dust removal by the separation and dust removal system 205, and then enters the water mist sprayer 204. The water pump 206 and spotlight 207 in the water mist sprayer 204 are activated. The water pump 206 pumps water from the water truck into the spray ring 208. When the airflow passes through the water mist sprayer 204, it blows the water sprayed from the spray ring 208 into a water mist. Due to the Tyndall effect (when a beam of light passes through a colloid, a bright path can be observed in the colloid), the light from the spotlight 207 forms a beam of light when it passes through the water mist. Activating this beam of light can alert oncoming vehicles. For the perimeter of the construction area, a cavity buffer unit 3 is installed. By traction, the buffer chambers 304 slide sequentially. The front end of the outermost buffer chamber 304 is equipped with a reflective warning strip 305, which provides a warning to oncoming vehicles. The reflective warning strip 305 clearly marks the boundary of the construction area, providing a warning to oncoming vehicles and helping to guide vehicles to change lanes in advance. During the stretching of the buffer housing 304, the bottom bracket 312 stretches the deceleration groove 311, pulling the speed bump 309 to the ground. Simultaneously, the speed bump 309 pulls the deceleration shaft 308 and the storage wheel 310 to rotate together. When storage is needed, simply rotate the storage wheel 310. The rotation of the storage wheel 310 drives the deceleration shaft 308 to rotate, which in turn causes the speed bump 309 to wind around. The speed bump 309 pulls the bottom bracket 312 through the deceleration groove 311, causing the bottom bracket 312 to be pulled by the tension. The buffer chamber 304 slides towards the buffer chamber 301; when the buffer chamber 304 is deployed, the small air compressor 314 inflates the air cushion 313, which expands and grows larger; when a vehicle fails to change direction in time, the front of the vehicle will collide with the outer buffer chamber 304 first, the buffer chamber 304 is squeezed and contracts with each other, and the deceleration slot 311 separates from the bottom slot 312. The vehicle wheel runs over the speed bump 309, and the kinetic energy is consumed through friction and material deformation, which can force the vehicle to stop. The air cushion 313 plays a buffering role when the vehicle hits the buffer chamber; the separation dust removal system 205 has multiple inertial baffles 209 to block the airflow from moving in a straight line. When the airflow turns rapidly, the dust particles are separated from the airflow under the action of inertial force.

[0025] The above is the specific workflow of this invention. This step can be repeated next time it is used.
