Description

Technical Field

[0001] The invention belongs to the technical field of safety monitoring, in particular to a buffer protection safety monitoring system for a highway maintenance operation area. Background Art

[0002] During highway construction and maintenance, road workers often work near active lanes of vehicles. Although various methods are used to guide traffic away from the work area, such as high road piers, traffic markings, warning poles and signal lights, for various reasons, errant vehicles may enter areas that are not suitable for driving and where workers are working. Therefore, a safety monitoring system is needed in front of the highway maintenance operation area to buffer out-of-control vehicles and provide safety protection for workers. The safety monitoring system includes three units: warning, monitoring and buffering, which monitor and warn the status of vehicles passing by. In the process of highway construction, the role of anti-collision buffer vehicles is particularly prominent. The speed of vehicles on highways is fast and the traffic volume is large. Once an accident occurs, the consequences are often very serious. The anti-collision buffer vehicle can build a buffer area between the accident vehicle and the construction area ahead through its powerful anti-collision buffer energy absorption module, effectively absorbing the impact energy and reducing the damage to construction personnel and equipment caused by the accident. At the same time, its eye-catching warning lights and reflective signs can also attract the attention of passing vehicles and reduce the probability of rear-end collisions. However, in actual application, first of all, there are many types of vehicles traveling on highways, such as cars: the chassis is low, and the horizontal position of the anti-collision beam on the front of the car is low; the chassis of off-road vehicles is higher than that of cars; the chassis of trucks is higher than the former two; therefore, during monitoring and protection, if the energy absorption module is placed at a high horizontal position, the car will easily drill under the energy absorption module during a collision, reducing the buffering protection effect and affecting the working effect of the buffering protection safety monitoring system; and, the conventional energy absorption module is flipped down from the anti-collision vehicle to a horizontal position facing the rear, which has requirements for the height limit, making it unable to adapt to various road conditions.

The rangefinder uses laser to monitor the distance between the vehicle and the operation area. When the distance is more than 100 meters, the speed of the rear vehicle is not detected; when the distance is within 100 meters, the speed of the vehicle directly behind is monitored to be more than 120 yards, and a weak warning is issued; when the distance is within 50 meters, the speed of the vehicle directly behind is monitored to be more than 80 yards, and a weak warning is issued; when the distance is within 10 meters, a strong warning is issued; The electric slide rail 1 is installed in the compartment of the anti-collision vehicle, and the electric slide rail 1 is powered on to drive the buffer assembly to slide to the rear of the anti-collision vehicle; a folding plate 11 is installed on the electric slide rail 1, and a lifting plate 12 is slidably connected to the side of the folding plate 11 away from the anti-collision vehicle; a crank 13 is rotatably connected to the edge of the lifting plate 12, a pull rope 14 is provided on the top of the folding plate 11, one end of the pull rope 14 is wound around the crank 13, and the buffer assembly is installed on the side of the lifting plate 12 away from the folding plate 11; The electric slide rail 1 is a conventional sliding device, and when the folding plate 11 is moved out of the anti-collision vehicle compartment, the electric slide rail 1 can be self-locking, so as to achieve the purpose of fixing the buffer assembly; the folding plate 11 is a conventional part formed by two plates being hinged by a torsion spring, one of the folding plates 11 is installed on the electric slide rail 1, and driven by the electric slide rail 1, the other plate can swing freely; when the buffer assembly is stored, the electric slide rail 1 drives one of the folding plates 11 to move into the compartment, and the other plate is folded into a horizontal state, at which time the folding plate 11 is in an L shape, and the storage work is completed; when the buffer assembly is extended out of the compartment, one of the folding plates 11 is moved out of the compartment, and the other plate is reset by the torsion spring and flipped from a horizontal state to a vertical state, at which time the folding plate 11 is in a vertical I shape, and the removal work is completed; The buffer assembly is composed of an energy absorbing bag 2, a collision plate 21, a frame 22 and a side plate 23; assembly plates 24 are evenly arranged on both sides of the frame 22, and every two assembly plates 24 can be connected and fixed to form a whole, and one end of the frame 22 is installed on the surface of the lifting plate 12, and the collision plate 21 is installed on the other end. Side plates 23 are installed at positions close to the lifting plate 12 on both sides of the frame 22, and the energy absorbing bag 2 is installed at the center of the frame 22; one end of the side plate 23 is hinged with a side guard plate 25 through a torsion spring, and one end of the side guard plate 25 is arc-shaped; the energy absorbing bag 2 is used to absorb energy and buffer when the vehicle collides; Specific work flow: During safety monitoring, the buffer assembly extends from the compartment of the anti-collision vehicle, and the folding plate 11 is in a vertical I shape, so that the lifting plate 12 can be lifted and slid on the side of the folding plate 11 away from the anti-collision vehicle; according to the lane position of the actual working area, the buffer assembly is placed in the following manner: When the work area is in the fast lane or other lanes, the vehicles traveling in the lane are all cars or off-road vehicles, whose chassis are at a lower horizontal position than that of truck chassis, and the anti-collision beam at the front of the vehicle is also at a lower position; therefore, the staff releases the pull rope 14 wrapped around the crank 13 by turning the crank 13; as the pull rope 14 is released, the crank 13, the lifting plate 12 and the buffer assembly descend until the buffer assembly descends to the specified position, so that the buffer assembly can cover the moving area of ​​the vehicle's anti-collision beam, achieve good contact between the buffer assembly and the vehicle's anti-collision beam, improve the vehicle's buffering effect, and avoid the vehicle from drilling under the buffer assembly due to collision buffering contact errors, thereby reducing the buffering effect, and at the same time, metal parts such as the collision plate 21 in the buffer assembly invade the cab, causing harm to the driver and passengers, and reducing the protection effect; When the work area is in the slow lane or other lanes, the vehicles traveling in the lane are all trucks or heavy trucks, and their chassis and anti-collision beams are at a higher position; therefore, the staff continues to wind the pull rope 14 around the crank 13 by turning the crank 13; as the winding of the pull rope 14 shortens, the crank 13, the lifting plate 12 and the buffer assembly rise to the specified position, so that the buffer assembly can cover the moving area of ​​the vehicle's anti-collision beam, and achieve a good contact effect between the buffer assembly and the vehicle's anti-collision beam; Through the above-mentioned multiple adjustment methods, the buffer assembly can take targeted adjustment measures according to different lanes and corresponding vehicle models, thereby improving the convenience of using the buffer assembly and expanding the scope of application; and the buffer assembly is moved out of the car body of the anti-collision vehicle by horizontal sliding. Compared with the conventional flip construction, it has a lower requirement for the height limit of the highway, further expanding the scope of application of the anti-collision vehicle on special highways, thereby improving the adaptability of the safety monitoring system; Furthermore, if the area of ​​the working area is large and a single buffer assembly cannot meet the requirements, the staff can install additional components on the left and right sides of the single buffer assembly as needed. The installation method is as follows: the uninstalled buffer assembly includes the energy absorption pack 2, the collision plate 21 and the frame 22; first, the installed side panels 23 and the side guard plates 25 are removed; then, the assembly plate 24 on the uninstalled frame 22 is aligned with the assembly plate 24 on the installed frame 22 and connected and fixed to each other. The connection and fixing method is a conventional connection structure, such as an L-shaped plate and an inverted L-shaped plate plugged and connected to each other; finally, the removed side panels 23 and side guard plates 25 are installed on both sides of the combined buffer assembly, and the installation of the buffer assembly is then completed; this method is like building blocks. You only need to plug and assemble to increase the buffer shielding area, which is convenient for the staff to assemble flexibly, while improving the convenience of building the safety monitoring system and improving practicality; When the vehicles collide, there will also be an offset collision. After the offset collision, the vehicle will pass over the anti-collision vehicle and hit the rear working area or guardrail, causing a secondary collision. Therefore, when the vehicle collides with an offset, the anti-collision beam of the vehicle contacts the arc-shaped parts of the collision plate 21 and the side guard plate 25 at the same time; after the collision, the collision plate 21 squeezes the frame 22 and the energy absorbing bag 2 inward, so that the collision plate 21 moves closer to the lifting plate 12, and the side guard plate 25 is hinged on the side plate 23, and the side plate 23 is fixedly installed on the lifting plate 12, so that the side plate 23 and the side guard plate 25 are The rigidity of the guard plate 25 is higher than that of the frame 22 and the energy absorbing bag 2; when the collision plate 21 moves backward, the arc-shaped part of the side guard plate 25 is squeezed to deflect, so that the side of the side guard plate 25 is directed toward the vehicle, and the side of the side guard plate 25 and the front of the collision plate 21 wrap the vehicle, increase the area of ​​the vehicle contacting the buffer assembly, wrap the vehicle therein, and intercept the trend of the vehicle passing over the buffer assembly through the side guard plate 25, avoid the vehicle passing over the anti-collision vehicle and causing a secondary collision, thereby improving the buffer protection effect, and further improving the practicality of the safety monitoring system; Furthermore, by providing the assembly plate 24, the components connected by the assembly plate 24, such as the frame 22 and the collision plate 21, can be simply disassembled and replaced, thereby improving the convenience of use and thus improving the practicality of the safety monitoring system.

[0020] Embodiment 2: On the basis of the first embodiment, the energy absorbing package 2 is divided into a first buffer zone 26, a second buffer zone 27 and a third buffer zone 28 according to the regions. The energy absorbing pad 3 is installed in the first buffer zone 26, and the first extrusion box 31 and the second extrusion box 32 are installed in the second buffer zone 27 and the third buffer zone 28 respectively. The first extrusion box 31 stores a foaming agent; the first extrusion box 31 and the second extrusion box 32 are respectively slidably connected with a first extrusion plate 33 and a second extrusion plate 34, and the top and bottom of the second extrusion box 32 are slidably connected with an expansion plate 35 through a spring, and the side of the expansion plates 35 at the upper and lower positions close to each other is an inclined surface, and one end of the second extrusion plate 34 contacts the inclined surfaces of the two expansion plates 35;‌ Nozzles 36 are evenly arranged on the side guard plate 25, and the nozzles 36 are connected to the first extrusion box 31 through a pipeline, and the nozzles 36 point to the middle position of the collision plate 21; The energy absorbing pad 3 is a component used for energy absorption and buffering on a conventional working vehicle; the foaming agent is a substance that solidifies after conventional spraying, such as polyurethane foam, and the solidification process is to add gas to the polyurethane prepolymer, and after spraying, a curing reaction occurs with moisture in the air to form a hard foam; this reaction usually starts within a few seconds after spraying and cures quickly; it also has strong adhesion and can be firmly bonded to various substrates; Pressure plates 37 are evenly arranged in the energy absorbing pack 2, and the pressure plates 37 are located between the energy absorbing pad 3, the first extrusion box 31 and the second extrusion box 32, respectively, and the edges of the pressure plates 37 are connected to the inner surface of the frame 22; the two sides of one of the pressure plates 37 are in contact with the energy absorbing pad 3 and the first extrusion plate 33, respectively, and the two sides of the other pressure plate are in contact with the first extrusion box 31 and the second extrusion plate 34, respectively; Specific working process: when the collision plate 21 moves backward, the collision plate 21 squeezes the energy absorbing pad 3, and the energy absorbing pad 3 absorbs and buffers the collision process; When the collision force is large, the collision plate 21 drives the first extrusion plate 33 to move through the energy absorbing pad 3. After the first extrusion plate 33 enters the first extrusion box 31, the foaming agent inside is squeezed out and sprayed onto the vehicle surface through the pipeline from the nozzle 36 on the side guard plate 25 to cover the vehicle surface. A layer of hard foam is quickly formed on the vehicle surface to improve the impact resistance of the vehicle. In addition, with the strong adhesion of the foaming agent, the integrity of the vehicle is maintained to prevent the internal parts of the vehicle cabin from being thrown out due to the collision, causing injuries to personnel, thereby improving the buffering and protection effects. When the collision force is too great, the collision plate 21 drives the energy absorbing pad 3, the first extrusion plate 33 and the first extrusion box 31 to contact the second extrusion plate 34, and the second extrusion plate 34 enters the second extrusion box 32 to contact the inclined surface of the expansion plate 35, pushing the expansion plate 35 out of the second extrusion box 32; the expansion plate 35 located at the top blocks the front of the vehicle, increasing the contact area when the vehicle continues to collide, avoiding the angle deviation or the tilting of the front of the vehicle during the collision process, thereby stabilizing the vehicle at the rear of the anti-collision vehicle and improving the buffering and protection effect of the safety monitoring system; the expansion plate 35 located at the bottom drops and contacts the ground, and as the second extrusion box 32 is impacted and moves backward, the second extrusion box 32 drives the expansion plate 35 contacting the ground below to move backward, so that the expansion plate 35 is in close contact with the ground while dragging on the ground, and a braking effect is generated by increasing the friction force, thereby reducing the displacement distance of the buffer assembly after being impacted, and reducing the moving distance of the anti-collision vehicle when it is impacted, thereby improving the buffering and protection effects; Through the cooperation of the first buffer zone 26, the second buffer zone 27 and the third buffer zone 28, the first buffer zone 26 plays a buffering role, the second buffer zone 27 plays a role in protecting the vehicle and the driver and passengers, and the third buffer zone 28 plays a role in reducing the movement of the anti-collision vehicle and protecting the workers in the work area. The above roles cooperate with each other to further improve the buffering protection effect of the safety monitoring system; Furthermore, since a pressure plate 37 is provided between the first buffer zone 26, the second buffer zone 27 and the third buffer zone 28, the second buffer zone 27 is enabled only after the first buffer zone 26 fails due to collapse, until the third buffer zone 28 is enabled, so as to achieve the purpose of using them one by one, so that when the second buffer zone 27 is not enabled, the replacement of the buffer assembly can be completed by replacing the components of the first buffer zone 26, thereby reducing the cost of use and improving practicality; and, in order to ensure that the purpose of using the buffer zone is paid attention to, the staff can adapt the hardness of the frame 22 in each area, for example, the hardness of the frame 22 in the first buffer zone 26, the second buffer zone 27 and the third buffer zone 28 is gradually increased, so that after the frame 22 of the first buffer zone 26 collapses, the frame 22 of the second buffer zone 27 will begin to collapse, thereby effectively improving the effect of graded buffering.

[0021] Embodiment three: On the basis of the second embodiment, a support plate 4 is hinged on the expansion plate 35 through a torsion spring, and the support plates 4 on adjacent expansion plates 35 are arranged alternately up and down, the support plate 4 located at the top is located on the side of the expansion plate 35 away from the energy absorbing pad 3, and the support plate 4 located at the bottom is located on the side of the expansion plate 35 close to the energy absorbing pad 3; when the expansion plate 35 is squeezed and extends out of the second squeezing box 32, the support plate 4 is driven to swing by the spring reset, and one side of the support plate 4 contacts the upper and lower surfaces of the second squeezing box 32; A flip plate 41 is hinged at the bottom of the expansion plate 35 through a torsion spring, and the flip plate 41 is located below the second extrusion box 32; when the expansion plate 35 located below the second extrusion box 32 is stationary, one end of the flip plate 41 contacts the bottom of the second extrusion box 32 and flips to a nearly horizontal state; when the expansion plate 35 located below the second extrusion box 32 descends, the flip plate 41 is driven by the torsion spring to flip to a nearly vertical state, and the end of the flip plate 41 away from the second extrusion box 32 contacts the ground; The end of the flip plate 41 away from the second extrusion box 32 is evenly provided with spikes 42; Specific working process: when the expansion plate 35 extends out of the second extrusion box 32, the support plate 4 rotates out from the expansion plate 35 with the hinged part as the center of the circle, and the surfaces of the two support plates 4 close to each other contact the top and bottom of the second extrusion box 32; the expansion plate 35 located at the top tilts backward when subjected to impact, and the support plate 4 located at the top supports it at the back; the expansion plate 35 located at the bottom is dragged on the ground and tilted forward, and the support plate 4 located at the bottom supports it at the front. The two support plates 4 staggered up and down support the two expansion plates 35, thereby improving the stability of the expansion plates 35 and thus improving the buffering and protection effect; Furthermore, when the anti-collision vehicle is in the slow lane, the second squeeze box 32 is lifted away from the ground. When the expansion plate 35 located below is lowered, the expansion plate 35 drives the flip plate 41 to descend. After the flip plate 41 is away from the bottom of the second squeeze box 32, it is reset by the torsion spring and flipped to a nearly vertical state. The end of the flip plate 41 away from the second squeeze box 32 contacts the ground, so that when the expansion plate 35 is in the slow lane, it can still contact and rub the ground through the flip plate 41 to provide sufficient braking force. Moreover, by providing the spikes 42, when the flip plate 41 contacts the ground, the spikes 42 are driven to contact the ground; when the flip plate 41 is dragged, since the flip plate 41 contacts the ground through the spikes 42 in an inclined state, the flip plate 41 gradually penetrates into the ground through the spikes 42 as it is dragged, thereby maintaining a sufficient braking effect, thereby improving the buffering and protection effect.

[0022] Embodiment 4: On the basis of the third embodiment, a guide plate 5 is installed at the bottom of the collision plate 21, and the guide plate 5 is tilted toward the ground; the top of the collision plate 21 is arc-shaped, and the top of the collision plate 21 is bent toward the anti-collision vehicle; An extension plate 51 is slidably connected to the bottom of the guide plate 5, and one end of the extension plate 51 contacts the ground; A high-pressure tank 52 containing a solenoid valve is provided in the expansion plate 35, and fire extinguishing materials are stored in the high-pressure tank 52; nozzles 53 are evenly provided on the guide plate 5, and the nozzles 53 are connected to the high-pressure tank 52 through a pipeline; a sensor 54 is provided at a portion of the expansion plate 35 close to the support plate 4, and the sensor 54 is connected to the solenoid valve; the sensor 54 is a conventional pressure sensor 54, the high-pressure tank 52 is a conventional high-pressure fire extinguishing tank with a solenoid valve, and the fire extinguishing material is a material used for extinguishing a fire on a car; A bending plate 55 is installed between the side guard plate 25 and the frame 22. One end of the bending plate 55 is hinged to the side guard plate 25 through a torsion spring, and the other end is connected to the assembly plate 24 through a torsion spring, and the assembly plate 24 close to the bending plate 55 is connected to the frame 22. The bending plate 55 is a conventional part formed by two plates being hinged by a torsion spring, which is the same as the folding plate 11. Specific working process: by setting the guide plate 5, if encountering a vehicle with a low horizontal position of the anti-collision beam, such as a sports car, the vehicle first contacts the guide plate 5 before contacting the collision plate 21, and goes uphill with the guidance of the guide plate 5, so that the front of the vehicle is tilted to the part of the collision plate 21 close to the arc, so as to achieve the purpose of wrapping the vehicle and fix the upper and lower positions of the front of the vehicle, and cooperate with the above-mentioned collision plate 21 and the side guard plate 25 to wrap and fix the left and right positions of the front of the vehicle, so as to further ensure the effect of fixing the front of the collision vehicle, avoid the situation of passing by due to offset collision, and thus improve the buffer protection effect; By providing the extension plate 51, when the anti-collision vehicle is located in the slow lane, the collision plate 21 rises. If a vehicle with a bottom anti-collision beam is traveling in this lane and collides, the vehicle can still contact the guide plate 5 through the transition and guidance of the extension plate 51, and is guided by the guide plate 5 to contact the arc-shaped portion of the collision plate 21, so as to achieve the purpose of wrapping the vehicle, increase the practicality of the guide plate 5, and further improve the buffer protection effect; When the expansion plate 35 extends out of the second extrusion box 32, the support plate 4 extends out of the expansion plate 35. After the sensor 54 is no longer squeezed, the solenoid valve in the high-pressure tank 52 is controlled to open, and the high-pressure tank 52 sprays the fire extinguishing material through the nozzle 53. Since the guide plate 5 faces the bottom of the vehicle, the nozzle 53 sprays the fire extinguishing material to the bottom of the vehicle, so as to prevent the occurrence of fire in vehicles such as trams due to collision in the first place, and improve the buffer protection effect by adding fire extinguishing measures; When the side guard plate 25 is stationary, the bending plate 55 is in a bent and overlapping state, and is stored between the side guard plate 25 and the frame 22; when the side guard plate 25 is deflected to intercept a vehicle, the side guard plate 25 pulls the bending plate 55 to stretch it from the overlapping state to the unfolded state; on the one hand, in order to cooperate with the side guard plate 25 to intercept the vehicle and improve the interception effect, thereby improving the buffering and protection effect; on the other hand, it is connected between the side guard plate 25 and the frame 22 to avoid excessive collision force, which causes the side guard plate 25 to be bent and causes the vehicle to pass by, thereby increasing the support of the side guard plate 25 and further improving the buffering and protection effect.
