[0002] Construction warning monitoring devices are usually used in traffic engineering construction to warn of roads that need maintenance and prohibition. Most of the existing warning monitoring devices are warning signs hung on fences, and lighting is set on the warning signs. However, when driving at night, some drivers are not focused, which may lead to failure to find the warning signs in time or the vehicle is too fast. They start braking when approaching the warning signs and fences, which will result in insufficient braking distance for the car, causing the car to hit the warning signs and fences, and then cause traffic accidents, resulting in large economic losses and safety hazards, and unable to achieve the expected warning effect.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a movable wheel and a brake pad. When the car drives onto the fixed block 1, the wheel of the car will squeeze the force plate. At this time, the force plate will flip over and drive the connecting block and the round rod to flip over and squeeze the piston rod 2 to move to the inside of the fixed box. At the same time, since the tire of the vehicle is subjected to the resistance of the force plate and vibrates under the action of the vehicle shock absorber, it can play a role in reminding the driver of the indoor movement. At this time, the driver of the indoor will start to brake. Due to the movement of the piston rod 2, the gas inside the fixed box can be pushed into the inside of the bent pipe, and the one-way valve is opened at the same time. The gas is sent to the inside of the mounting block through the bent pipe and the connecting pipe, pushing the piston rod 1 and the brake pad to move upward, releasing the contact between the brake pad and the brake disc, and releasing the fixation of the movable wheel. At this time, the movable wheel has movable performance, and the spring 1 is compressed. Under the movable action of the movable wheel, the tire of the car can be idling on the movable wheel and slide under the action of the car's own inertia. This design can reduce the travel distance of the wheel under the rotation action, and the driver can use this time to brake until the wheel is locked.

[0014] 2. The present invention provides a piston rod three and a slide rail. When the automobile wheel squeezes the force plate, it can be determined that a vehicle has passed. At this time, the control end will start the air pump to extract external gas and transport it to the reserve tube through the round tube, so that the air pressure inside the reserve tube increases, and pushes the piston four to move outward, squeezes the spring two, and stores the gas inside the reserve tube. Under the inertia of the automobile, the rolling of the movable wheel can be used to drive it to the fixed block two, and the automobile tire squeezes the push plate to move. When the automobile passes the fixed block two, the friction between the wheel and the brake plate can be increased through the resistance of multiple steel belts, thereby further reducing the braking distance of the automobile. The movement of the connecting rod, the movable frame and the sealing plate can push the connecting rod, the movable frame and the sealing plate to move, so that the sealing plate releases the sealing of the air chamber two. At this time, the spring three is compressed, and at the same time, under the elastic recovery effect of the spring two, the air pressure inside the reserve tube is quickly pushed into the air chamber one through the air chamber two, and drives the piston rod three to move outward. The tension spring is stretched, and the piston rod three pushes the base, the fence monitoring component and the early warning board to move backward for a distance. At the same time, the scraper can scrape away the impurities in the slide rail as the base moves, so as to prevent the base from getting stuck during the movement, thereby preventing the car from hitting the fence monitoring component due to failure to brake in time, thereby ensuring the safety of personnel.

[0015] 3. The present invention provides a movable plug and a fixed rod. When the car passes through the force-bearing plate, the elastic restoring effect of the spring 1 can drive the piston rod 1 and the brake pad to reset. At this time, the piston rod 1 pushes the gas inside the mounting block into the curved pipe, and slowly sends the gas back to the inside of the fixed box through the circular hole, so that the brake pad is slowly reset and time is left for the car to pass through the movable wheel. When the brake pad is reset and abuts against the brake disc, the movable wheel can be fixed again, thereby preventing the tire from slipping when the car is backed out of the distance reduction mechanism. The reset of the brake pad can drive the mounting rod, the circular shaft, the pushing plate and the fixed plate to reset, and drive the exhaust duct and the movable plug to reset downward, so that the movable plug releases the closure of the exhaust duct and the movable hole, and allows the air cavity 1 to communicate with the outside world through the exhaust duct. Under the elastic restoring effect of the tension spring, the base, the fence monitoring assembly and the early warning board can be driven to reset, thereby ensuring that the car can safely withdraw from the distance reduction mechanism, and at the same time making the device recoverable after use.

[0020] The above scheme is adopted: when the air pressure inside the mounting block 15 increases, the piston rod 16 and the brake pad 17 are pushed upward, the abutment of the brake pad 17 on the brake disc 14 is released, and the fixation of the movable wheel 13 is released. At this time, the movable wheel 13 has movable performance, and the spring 18 is compressed. Under the movable action of the movable wheel 13, the automobile tire can idle on the movable wheel 13 and slide under the action of the automobile's own inertia, thereby reducing the travel distance generated by the rotation of the wheel.

[0023] like Figures 2 to 6As shown, a force-bearing plate 116 is hinged on the upper part of the interior of the fixed block 11, a connecting block 117 is connected to the bottom of the force-bearing plate 116, and a round rod 118 that can be sleeved inside the pushing block 115 is connected to the inner side of the connecting block 117.

[0024] The above scheme is adopted: by setting the force plate 116, when the wheel of the car squeezes the force plate 116, the force plate 116 will flip over and drive the connecting block 117 and the round rod 118 to flip over and squeeze the piston rod 114 to move to the inside of the fixed box 113. At the same time, since the tire of the vehicle is resisted by the force plate 116 and vibrates under the action of the vehicle shock absorber, it can serve to remind the driver indoors of the movement, and the driver indoors will brake at this time.

[0025] like Figure 8 As shown, a lighting lamp 37 is installed above the interior of the warning plate 36 , and a scraper 34 located inside the mounting plate 31 is connected to the bottom of the base 33 .

At the same time, when the base 33 moves, the scraper 34 can scrape away the impurities in the slide rail 32 as the base 33 moves, thereby preventing the base 33 from getting stuck during the movement.

[0027] like Fig. 9 As shown, three air cavities 22 are opened inside the brake plate 21, and a piston rod 3 23 is sleeved inside the air cavity 22. One end of the piston rod 3 23 extends to the outside of the brake plate 21 and is connected to the mounting plate 31. A fixing ring 24 is fixedly installed inside the air cavity 22, and a tension spring 25 is connected to one side of the fixing ring 24. The other end of the tension spring 25 is connected to the piston rod 3 23.

[0028] The above scheme is adopted: by setting the piston rod three 23, when the air pressure inside the air chamber 22 increases, the piston rod three 23 can be driven to move outward, the tension spring 25 is stretched, and the piston rod three 23 pushes the base 33, the fence monitoring component 35 and the early warning plate 36 to move backward for a distance, thereby preventing the car from colliding with the fence monitoring component 35 due to failure to brake in time, thereby ensuring the safety of people.

[0029] like Fig. 9As shown, the brake plate 21 has an air cavity 26 connected to the air cavity 1 22 inside, a reserve tube 27 is connected to the outside of the brake plate 21, a section of the reserve tube 27 is connected to the air cavity 26, a piston 4 28 is sleeved inside the reserve tube 27, a spring 29 is sleeved on the outer surface of the piston 4 28, the other end of the spring 29 is connected to the reserve tube 27, the brake plate 21 has an air pump 210 located below the reserve tube 27 connected to the outside, a round tube 211 is connected to one side of the air pump 210, and the other end of the round tube 211 is connected to the reserve tube 27.

[0030] The above scheme is adopted: by setting a reserve tube 27, when the automobile wheel squeezes the force plate 116, it can be determined that a vehicle is passing. At this time, the control end will start the air pump 210, extract the external gas and transport it to the reserve tube 27 through the circular tube 211, so that the air pressure inside the reserve tube 27 increases, and pushes the piston four 28 to move outward, squeezing the spring two 29, so that the gas can be stored inside the reserve tube 27.

[0031] like Fig.16 As shown, one side of the bottom of the brake plate 21 is connected to a fixed block 220, and the internal movable sleeve of the fixed block 220 is connected to a push plate 221, the inner side of the push plate 221 is connected to a connecting rod 222, the other end of the connecting rod 222 extends to the interior of the brake plate 21 and is connected to a movable frame 223, the movable frame 223 is slidably installed in the interior of the brake plate 21, one side of the movable frame 223 is connected to a sealing plate 225 that can be snapped into the interior of the air cavity 26, the inner side of the movable frame 223 is connected to a spring 3 224, and the other end of the spring 3 224 is connected to the brake plate 21.

[0032] The above scheme is adopted: by setting the sealing plate 225, due to the movement of the push plate 221, the connecting rod 222, the movable frame 223 and the sealing plate 225 can be pushed to move, so that the sealing plate 225 releases the sealing of the air cavity 26. At this time, the spring 3 224 is compressed, and at the same time, under the elastic recovery action of the spring 2 29, the air pressure inside the reserve tube 27 can be quickly pushed into the interior of the air cavity 1 22 through the air cavity 26.

[0033] like Figures 12 to 15 As shown, the brake plate 21 has a movable hole 212 below the second air cavity 26, and the movable hole 212 can communicate with the second air cavity 26. The brake plate 21 has exhaust passages 213 located on both sides of the movable hole 212 and connected thereto. A movable plug 214 is sleeved inside the movable hole 212, and a fixed rod 215 located inside the exhaust passage 213 is connected to the outer side of the movable plug 214. The other end of the fixed rod 215 extends to the outside of the exhaust passage 213 and is fixedly sleeved with a fixed plate 216.

[0034] The above scheme is adopted: by setting the movable hole 212, when the brake pad 17 moves upward, it can drive the mounting rod 219, the round shaft 218, the push plate 217 and the fixed plate 216 to move upward, and drive the exhaust duct 213 and the movable plug 214 to move upward, so that the movable plug 214 can seal the exhaust duct 213 and the movable hole 212. When the car passes the push plate 221, due to the elastic recovery effect of the spring three 224, the connecting rod 222, the push plate 221, the movable frame 223 and the sealing plate 225 can be driven to reset, and the air cavity two 26 can be closed.

[0035] like Figures 12 to 15 As shown, the other end of the fixed plate 216 is connected to a push plate 217, and a circular shaft 218 is movably sleeved inside the push plate 217. One end of the circular shaft 218 extends to the outside of the push plate 217 and is fixedly sleeved with a mounting rod 219, which is connected to the brake pad 17.

[0036] The above scheme is adopted: by setting the mounting rod 219, the reset of the brake pad 17 can drive the mounting rod 219, the round shaft 218, the push plate 217 and the fixed plate 216 to reset, and drive the exhaust duct 213 and the movable plug 214 to reset downward, so that the movable plug 214 releases the closure of the exhaust duct 213 and the movable hole 212, and allows the air cavity 22 to communicate with the outside world through the exhaust duct 213. Under the elastic recovery action of the tension spring 25, the base 33, the fence monitoring component 35 and the early warning plate 36 can be driven to reset.

[0037] The working principle and use process of the present invention: During arrangement, the distance reduction mechanism 1 , the braking mechanism 2 and the early warning monitoring mechanism 3 are fixed on the road surface before construction by expansion screws, and the lighting lamp 37 is turned on to illuminate the surface of the early warning board 36 .

[0038] When the car drives onto the fixed block 11, the wheels of the car will press the force plate 116. At this time, the force plate 116 will flip over and drive the connecting block 117 and the round rod 118 to flip over and squeeze the piston rod 114 to move to the inside of the fixed box 113. At the same time, since the tire of the vehicle is resisted by the force plate 116 and vibrates under the action of the vehicle shock absorber, it can serve to remind the driver of the movement. At this time, the driver will start to brake. Due to the movement of the piston rod 114, the gas inside the fixed box 113 can be pushed into the inside of the bent pipe 110. When the one-way valve 111 is opened, the gas is sent into the interior of the mounting block 15 through the bend pipe 110 and the connecting pipe 19, pushing the piston rod 16 and the brake pad 17 to move upward, releasing the abutment of the brake pad 17 on the brake disc 14, and releasing the fixation of the movable wheel 13. At this time, the movable wheel 13 has movable performance, and the spring 18 is compressed. Under the movable action of the movable wheel 13, the automobile tire can idle on the movable wheel 13 and slide under the action of the automobile's own inertia, thereby reducing the travel distance of the wheel under the rotation. At the same time, the driver can use this time to brake until the wheel locks.

[0039] When the car wheel squeezes the force plate 116, it can be determined that a vehicle is passing by. At this time, the control end will start the air pump 210, extract the external gas and transport it to the reserve tube 27 through the round tube 211, so that the air pressure inside the reserve tube 27 increases, and pushes the piston 28 to move outward, squeezing the spring 29, and storing the gas in the reserve tube 27. Under the inertia of the car, the rolling of the movable wheel 13 can be used to drive it to the fixed block 220, and the car tire squeezes the push plate 221 to move. When the car passes the fixed block 220, the friction between the wheel and the brake plate 21 can be increased through the resistance of multiple steel belts 226, further reducing the braking distance of the car. Due to the movement of the push plate 221, the continuous The rod 222, the movable frame 223 and the sealing plate 225 move, so that the sealing plate 225 releases the seal of the air chamber 26. At this time, the spring 3 224 is compressed. At the same time, under the elastic recovery action of the spring 29, the air pressure inside the reserve tube 27 is quickly pushed into the interior of the air chamber 1 22 through the air chamber 26, and drives the piston rod 3 23 to move outward. The tension spring 25 is stretched, and the piston rod 3 23 pushes the base 33, the fence monitoring component 35 and the early warning plate 36 to move backward for a distance. At the same time, the scraper 34 can scrape away the impurities in the slide rail 32 as the base 33 moves, so as to prevent the base 33 from getting stuck during the movement, thereby preventing the car from hitting the fence monitoring component 35 due to failure to brake in time.

[0040] When the brake pad 17 moves upward, it can drive the mounting rod 219, the circular shaft 218, the pushing plate 217 and the fixed plate 216 to move upward, and drive the exhaust duct 213 and the movable plug 214 to move upward, so that the movable plug 214 can seal the exhaust duct 213 and the movable hole 212. When the car passes the push plate 221, due to the elastic recovery effect of the spring three 224, the connecting rod 222, the push plate 221, the movable frame 223 and the sealing plate 225 can be driven to reset, and the air cavity 226 can be closed. When the car passes the force plate 116, due to the elastic recovery effect of the spring one 18, the piston rod one 16 and the brake pad 17 can be driven to reset. At this time, the piston rod one 16 pushes the gas inside the mounting block 15 into the bent pipe 110, and slowly sends the gas back to the fixed box 113 through the circular hole 112. When the brake pad 17 is reset and abuts against the brake disc 14, the movable wheel 13 can be fixed again, thereby preventing the tire from slipping when the car is backed out of the distance reduction mechanism 1. The reset of the brake pad 17 can drive the mounting rod 219, the circular shaft 218, the push plate 217 and the fixing plate 216 to reset, and drive the exhaust duct 213 and the movable plug 214 to reset downward, so that the movable plug 214 releases the closure of the exhaust duct 213 and the movable hole 212, and allows the air cavity 22 to communicate with the outside through the exhaust duct 213. Under the elastic recovery action of the tension spring 25, the base 33, the fence monitoring component 35 and the warning plate 36 can be driven to reset, thereby ensuring that the car can safely exit from the distance reduction mechanism 1.
