An implementation method of a forced parking type safety warning device for highway construction comprises the following steps:

s1: the vehicle is reminded and decelerated through the deceleration strip 11 and the deceleration mechanism 1;

s3: the vehicle is further buffered, supported and decelerated by the impact of the second buffer mechanism 3;

s4: the third buffer mechanism 4 is used for buffering and absorbing the residual stress of vehicle impact, and forcibly braking the vehicle.

This highway construction is with forcing parking formula safety warning device's theory of operation:

firstly, the whole device is arranged in front of a construction area, in daily use, the light of the audible and visual alarm 212 reminds the coming and going vehicles to pay attention to the construction area, when the attention of the drivers is dispersed or the vehicles have brake faults, the vehicles firstly drive through the speed reducing belts 11, early warning is realized on the drivers through strong jolt of the speed reducing belts 11, the drivers can conveniently brake in time, when the drivers are difficult to control due to drunk driving or the vehicles have brake faults, the vehicles continuously start towards the direction of the first buffer mechanism 2 until front wheels of the vehicles are contacted with the arc-shaped speed reducing plates 12, because the tops of the arc-shaped speed reducing plates 12 are in arc-shaped design, the vehicles can be subjected to inclined design through the arc-shaped speed reducing plates 12 when driving, consumption is realized on the whole advancing stress of the vehicles through the ascending climbing force of the vehicles, the effect of reducing the vehicle speed is achieved, and when the vehicles pass through the arc-shaped speed reducing plates 12, the arc-shaped speed reducing plates 12 are stressed, the arc-shaped speed reducing plates 12 sink under pressure and are contacted with the pressure switch 132, the sound module of the audible and visual alarm 212 can give an alarm to the drivers and remind the drivers and the drivers to give out warning, thereby reminding the drivers and simultaneously to avoid early warning on the surrounding of the construction personnel;

when the vehicle cannot be braked continuously, the vehicle collides with the buffer cushion 211 on the surface of the first buffer plate 21 and further collides with the first buffer plate 21, and at the moment, the vehicle can be buffered and decelerated primarily effectively through the compression of the buffer springs 231 arranged on the side surfaces of the multiple groups of second buffer plates 23;

when the third buffer plate 24 pushes the sealing piston 333 to further compress the air inside the first air path pipe 311 through the transmission link 332, the air pressure inside the first air path pipe 311 is increased, the sealing slider 343 can be pushed to move to a pipeline on the side wall of the sealing slider 343 to be contacted with the inside of the circular groove 342, at this time, the pressure air inside the first air path pipe 311 can enter the inside of the buffer air bag 341 through the sealing slider 343 to inflate and expand the buffer air bag 341, when the third buffer plate 24 moves towards the fourth buffer plate 31, the third buffer plate 24 is supported and buffered, along with the movement of the third buffer plate 24, the compression degree of the first air path pipe 311 is gradually increased, the inflation and expansion volume of the buffer air bag 341 is larger, the primary buffering is realized through the compression of the second compression spring 331, the second compression spring 331 can further support and buffer the buffer effect on the third buffer plate 24 through the expansion of the 5 buffer air bag 341 in the buffering process, the multistage buffering is realized, the high-efficiency stress relief of the third buffer plate 24 and the high-efficiency buffer damping of the vehicle is realized;

while the increase in the pressure inside the first air passage pipe 311 may push the buffering blade 351 to be extended,

the edging part through the buffering blade 351 can enable the buffering blade 351 to be inserted into soil and be tightly abutted with the soil 0 inside, the passivation design of one side of the third buffer plate 24 is kept away from through the buffering blade 351, when the vehicle stress pushes the fourth buffer plate 31 to move, one part of the stress for pushing the fourth buffer plate 31 to move by the vehicle is converted into the pressure to the soil of one side of the third buffer plate 24 in the vertical downward and horizontal directions, and the reaction force of the soil is used for rushing the vehicle

The impact stress is reduced by the friction force and the stress of the soil to the buffer blade 351, so that the impact of the fourth buffer plate 31 is reduced by improving the stress between the soil and the fourth buffer plate 31 when the impact occurs 5, and the buffering and braking effects are realized;

and when the residual stress of the fourth cushion plate 31, which is subjected to the impact, acts on the fifth cushion plate 41 through the third cushion chamber 43, the residual stress is compressed by the cushion mechanism inside the third cushion chamber 43,

when making the inside compressed air of second air path pipe 411 by further compression, the inside compressed air of second air path pipe 4110 can promote both sides system blade group 441 and stretch out, and then can show the area of contact who promotes fixed awl 44 and soil, improve soil to the holistic resistance of fixed awl 44, prevent that fifth buffer board 41 is not hard up, the support frame that cooperation fifth buffer board 41 side set up can realize absorbing stress, and prevent fifth buffer board 41 from continuing to move, realize the elimination to vehicle striking residual stress, realize the compulsory braking to the vehicle.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
