Description
Technical Field
[0001] This invention relates to the field of highway bridge anti-collision technology, specifically to a highway bridge anti-collision device for transportation construction. Background Technology
[0002] During long-distance driving, drivers may become drowsy due to fatigue. Since there is no external interference to prevent this, cars traveling on highway bridges may veer off course and crash into the guardrails on either side of the bridge. However, existing highway bridge guardrails only provide basic protection and cannot neutralize the energy generated by the impact. Therefore, cars often suffer irreversible consequences after hitting the guardrails. In some cases, due to excessive speed, cars may even roll over after hitting the guardrails and fall off the highway bridge. Summary of the Invention
[0003] This invention proposes a highway bridge anti-collision device for traffic construction, which solves the problem in related technologies where, when the driver is drowsy, there is no external interference to distract the driver, causing the car to crash into the guardrails on both sides of the bridge. Furthermore, since existing guardrails only provide a simple protective measure and cannot neutralize the energy generated by the impact, the car often suffers irreversible consequences after hitting the guardrail. In some cases, due to excessive speed, the car rolls over after hitting the guardrail and falls off the highway bridge.
[0004] The technical solution of the present invention is as follows:
[0005] A collision avoidance device for highway bridges used in traffic construction includes a bottom fixing block, a slope block, a fixing post, a top fixing block, a fixing shaft, an auxiliary guiding component, a first braking component, a second braking component, and a protective component. The bottom fixing block is installed on one side of the highway bridge. The slope block is installed on the side wall of the bottom fixing block, and a deceleration groove is provided on the surface of the slope block. The fixing post is installed on the bottom fixing block, and the top fixing block is installed at the top of the fixing post. The fixing shaft is located between the bottom fixing block and the top fixing block. The auxiliary guiding component is installed on the fixing shaft and is used to assist in guiding vehicles. The first braking component is installed on the fixing shaft and is used to brake the auxiliary guiding component. The second braking component is installed on the fixing post and is used to brake the vehicle. The protective component is installed on the top fixing block.
[0006] The auxiliary guidance component includes:
[0007] A hub, which is rotatably mounted on the fixed shaft;
[0008] A pressure sensing probe is disposed on the outer side wall of the wheel hub;
[0009] A buffer pad is disposed on the outer side wall of the wheel hub and surrounds the outside of the pressure sensing probe;
[0010] Anti-skid tire, the anti-skid tire is disposed on the outer side wall of the wheel hub, and the anti-skid tire surrounds the outside of the buffer pad.
[0011] The first braking assembly includes:
[0012] A first fixing frame is mounted on the fixing shaft;
[0013] A double-headed electric cylinder, wherein the double-headed electric cylinder is mounted on the first fixed frame;
[0014] An insert block is mounted on the telescopic rod of the double-headed electric cylinder.
[0015] The second braking assembly includes:
[0016] A lifting assembly is provided on the fixed column, and the lifting assembly is disposed in the mounting slot of the fixed column;
[0017] A movable block, which is mounted on the lifting assembly;
[0018] A brake plate is disposed on the side wall of the movable block, and the top of the brake plate is provided with a plurality of protrusions.
[0019] The lifting assembly includes:
[0020] A threaded rod is rotatably disposed in the mounting slot of the fixed column, and the threaded rod is threaded through the movable block;
[0021] A first motor is disposed in the mounting slot of the fixed column, and the output shaft of the first motor is fixedly connected to the threaded rod.
[0022] The protective components include:
[0023] A steering assembly, the steering assembly being disposed on the side wall of the top fixing block;
[0024] A second mounting bracket is disposed on the steering assembly;
[0025] The first elastic pad is disposed on the side wall of one end of the second fixing frame;
[0026] The second elastic pad is disposed on the side wall at the other end of the second fixing frame.
[0027] The steering component includes:
[0028] The third fixing frame is disposed on the side wall of the top fixing block;
[0029] A fixing rod is rotatably mounted on the third fixing frame, and the second fixing frame is mounted on the fixing rod;
[0030] The second motor is mounted on the side wall of the top fixing block, and the output shaft of the second motor is fixedly connected to the fixing rod.
[0031] To fix the position of the protective component and prevent it from shifting due to excessive impact from the vehicle, the above solution further includes a first electric cylinder and a second electric cylinder. The first electric cylinder is mounted on the side wall of the fixed column, and its telescopic rod is inserted into the side wall of the second fixed frame. The second electric cylinder is mounted on the second fixed frame, and its telescopic rod passes through the side wall of the top fixed block.
[0032] The working principle and beneficial effects of this invention are as follows:
[0033] 1. In this invention, when a driver falls asleep while driving at low speed, the car deviates and veers towards the outside of the highway bridge. The car's tires first contact the slope of the ramp block, and then the tires contact the deceleration blocks on the ramp block, causing the car to vibrate and disturb the drowsy driver, waking him up. The driver then begins to apply the brakes to brake the car, and the deceleration blocks on the ramp block assist the driver in braking. As the car continues to move towards the outside of the highway bridge, the tires will contact the deceleration grooves on the ramp block, which further assist in braking the car.
[0034] 2. In this invention, when the driver, in conjunction with the deceleration blocks and deceleration grooves, still cannot stop the car or return it to its normal path, the car will first contact the auxiliary guidance component. The auxiliary guidance component will assist in correcting the direction of the car, and at the same time, the buffer pad will absorb part of the impact force of the car. As the car continues to move outward, it will contact the first elastic soft pad, which will further absorb the impact force of the car. Through the cooperation of the auxiliary guidance component and the first elastic soft pad, the impact force generated by the low-speed car is absorbed, and the low-speed car returns to its normal path.
[0035] 3. In this invention, when the driver falls asleep while driving at high speed, after the car hits the auxiliary guide component and the first elastic cushion, when the pressure sensing probe receives an excessive impact force from the car, the dual-head electric cylinder, the first motor, and the second motor will start simultaneously to provide comprehensive braking and protection for the car. The first braking component keeps the auxiliary guide component stationary, and the stationary anti-skid tires brake the car. At this time, the entire car is completely above the brake plate, and the brake plate begins to rise, lifting the entire car upwards and making the car suspended in the air. Furthermore, the protective component that moves to the top fixed block prevents the car from rolling over during braking and falling off the highway bridge.
[0036] Therefore, compared with existing guardrails, this device can not only distract the driver before the car hits the fixed post, helping the driver to wake up from drowsiness, but also absorb the impact force generated by the car and brake the car, reducing the damage caused by the car hitting the fixed post. At the same time, during the braking process, it can also prevent the car from crossing the top fixed block and falling off the highway bridge. Attached Figure Description

Detailed Implementation
[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0051] like Figures 1-9 As shown, a highway bridge anti-collision device for traffic construction includes a bottom fixing block 1, a slope block 2, a fixing column 3, a top fixing block 4, a fixing shaft 5, an auxiliary guiding component 100, a first braking component 200, a second braking component 300, and a protective component 500. The bottom fixing block 1 is installed on one side of the highway bridge. The slope block 2 is installed on the side wall of the bottom fixing block 1. The surface of the slope block 2 is provided with deceleration, and a deceleration groove 25 is formed on the slope block 2. The fixing column 3 is installed on the bottom fixing block 1. The top fixing block 4 is installed on the top of the fixing column 3. The fixing shaft 5 is installed between the bottom fixing block 1 and the top fixing block 4. The auxiliary guiding component 100 is installed on the fixing shaft 5 for auxiliary guidance of vehicles. The first braking component 200 is installed on the fixing shaft 5 for braking the auxiliary guiding component 100. The second braking component 300 is installed on the fixing column 3 for braking vehicles. The protective component 500 is installed on the top fixing block 4.
[0052] The auxiliary guidance assembly 100 includes a hub 6, a pressure sensing probe 7, a buffer pad 8, and an anti-skid tire 9. The hub 6 is rotatably mounted on a fixed shaft 5. The pressure sensing probe 7 is mounted on the outer side wall of the hub 6. The buffer pad 8 is mounted on the outer side wall of the hub 6 and surrounds the outside of the pressure sensing probe 7. The anti-skid tire 9 is mounted on the outer side wall of the hub 6 and surrounds the outside of the buffer pad 8.
[0053] As the car hurtles toward the sides of the highway bridge, it first comes into contact with the auxiliary guidance component 100. One corner of the car hits the outer anti-skid tire 9, causing the anti-skid tire 9 to deform. The inner buffer pad 8 absorbs part of the impact force generated by the car's collision. In conjunction with the wheel hub 6, which is rotatably mounted on the fixed axle 5, it rotates upon impact to provide auxiliary guidance for the car, helping it return to its normal track and thus reducing the impact damage. Furthermore, when the car hits the pressure sensing probe 7, the pressure sensor 7 determines whether to activate the first braking component 200, the second braking component 300, and the protective component 500.
[0054] The first braking assembly 200 includes a first fixing frame 10, a double-headed electric cylinder 11, and a plug 12. The first fixing frame 10 is mounted on a fixing shaft 5, the double-headed electric cylinder 11 is mounted on the first fixing frame 10, and the plug 12 is mounted on the telescopic rod of the double-headed electric cylinder 11.
[0055] When the car hits the auxiliary guide assembly 100, the pressure sensing probe 7 is subjected to excessive impact force. The first braking assembly 200 begins to brake the auxiliary guide assembly 100. The dual-head electric cylinder 11 is activated. The extension rod of the dual-head electric cylinder 11 drives the insert 12 to move towards the connecting rod of the wheel hub 6. The insert 12 is inserted into the connecting rod of the wheel hub 6, preventing the wheel hub 6 from rotating. Then, the stationary anti-skid tire 9 provides auxiliary braking for the car.
[0056] The second braking assembly 300 includes a lifting assembly 400, a moving block 13, and a brake plate 14. The fixed column 3 is provided with an installation through groove. The lifting assembly 400 is disposed in the installation through groove of the fixed column 3. The moving block 13 is disposed on the lifting assembly 400. The brake plate 14 is disposed on the side wall of the moving block 13, and the top of the brake plate 14 is provided with multiple protrusions.
[0057] The lifting assembly 400 includes a threaded rod 15 and a first motor 16. The threaded rod 15 is rotatably disposed in the mounting slot of the fixed column 3 and the threaded rod 15 is threaded through the moving block 13. The first motor 16 is disposed in the mounting slot of the fixed column 3 and the output shaft of the first motor 16 is fixedly connected to the threaded rod 15.
[0058] Simultaneously, when the pressure sensing probe 7 is subjected to excessive impact force, the second braking assembly 300 begins to perform the main braking operation on the car. The first motor 16 starts and drives the threaded rod 15 to rotate, causing the moving block 13 to move the brake plate 14 upward in the mounting slot of the fixed column 3, thereby lifting the car off the ramp block 2. The distance between each brake plate 14 is greater than the diameter of the car tire, and the brake plate 14 hooks onto the car chassis through multiple protrusions.
[0059] The protective assembly 500 includes a steering assembly 600, a second fixing frame 17, a first elastic pad 18, and a second elastic pad 19. The steering assembly 600 is disposed on the side wall of the top fixing block 4, the second fixing frame 17 is disposed on the steering assembly 600, the first elastic pad 18 is disposed on the side wall of one end of the second fixing frame 17, and the second elastic pad 19 is disposed on the side wall of the other end of the second fixing frame 17.
[0060] The steering assembly 600 includes a third fixed frame 20, a fixed rod 21, and a second motor 22. The third fixed frame 20 is disposed on the side wall of the top fixed block 4, the fixed rod 21 is rotatably disposed on the third fixed frame 20, the second fixed frame 17 is disposed on the fixed rod 21, the second motor 22 is disposed on the side wall of the top fixed block 4, and the output shaft of the second motor 22 is fixedly connected to the fixed rod 21.
[0061] When the car hits the pressure sensor 7, and the pressure sensor 7 is not subjected to excessive impact force, the protective component 500 is in a vertical downward state. When the car hits the anti-skid tire 9, the first elastic soft pad 18 assists the buffer pad 8 to absorb part of the impact force generated by the car impact, further reducing the impact damage to the car.
[0062] When a car crashes into the pressure sensor 7, and the pressure sensor 7 experiences excessive impact, the protective component 500 activates to prevent the car from rolling over during the impact and falling off the highway bridge over the top fixing block 4, resulting in a fatal accident. The second motor 22 starts, driving the fixing rod 21 to rotate on the third fixing frame 20. This causes the second fixing frame 17, mounted on the third fixing frame 20, to rotate along with the fixing rod 21, moving the second elastic pad 19 above the top fixing block 4. Even if the car rolls over during the impact, it can be protected by the second elastic pad 19 and the third fixing frame 20. The second elastic pad 19 absorbs part of the impact force, preventing the car from falling off the highway bridge over the top fixing block 4.
[0063] In order to fix the position of the protective component 500 and prevent the protective component 500 from shifting due to excessive impact from the car, the above solution further includes a first electric cylinder 23 and a second electric cylinder 24. The first electric cylinder 23 is set on the side wall of the fixed column 3 and the telescopic rod of the first electric cylinder 23 is inserted into the side wall of the second fixed frame 17. The second electric cylinder 24 is set on the second fixed frame 17 and the telescopic rod of the second electric cylinder 24 passes through the side wall of the top fixed block 4.
[0064] When the protective component 500 is in a vertically downward position, the first electric cylinder 23 is activated, and the telescopic rod of the first electric cylinder 23 is inserted into the side wall of the second fixing frame 17, so that the protective component 500 is fixed on the fixing post 3, preventing the third fixing frame 20 from being displaced when the car hits the first elastic soft pad 18. When the protective component 500 moves above the top fixing block 4, the second electric cylinder 24 is activated, and the telescopic rod of the second electric cylinder 24 is inserted into the side wall of the top fixing block 4, so that the protective component 500 is fixed on the top fixing block 4, preventing the third fixing frame 20 from being displaced when the car hits the second elastic soft pad 19.
[0065] In summary, the working principle of this highway bridge anti-collision device for transportation construction is as follows:
[0066] When a driver falls asleep while driving at low speed on a highway bridge, the car slowly shifts to either side of the bridge. The car's tires first contact the slope of ramp block 2, and then the speed bumps on ramp block 2, causing the car to vibrate and disturb the drowsy driver, waking him up. The driver then applies the brakes, and the speed bumps on ramp block 2 assist in braking. As the car continues to move towards the outside of the bridge, the tires will contact the speed bump grooves 25 on ramp block 2, which further assist in braking the car.
[0067] When the driver, with the help of the speed bumps and speed grooves 25, still cannot stop the car or return it to its normal path, the car will first come into contact with the auxiliary guidance component 100. One corner of the car will hit the outer anti-skid tire 9, causing the anti-skid tire 9 to deform. The inner buffer pad 8 will absorb part of the impact force generated by the car impact. In conjunction with the wheel hub 6, which is rotatably mounted on the fixed axle 5, it will rotate when impacted to assist in guiding the car back to its normal track. If the car continues to travel outward, it will come into contact with the first elastic soft pad 18. The first elastic soft pad 18 will further absorb the impact force of the car. Through the cooperation of the auxiliary guidance component 100 and the first elastic soft pad 18, the impact force generated by the low-speed car is absorbed, and the low-speed car returns to its normal path.
[0068] When a driver falls asleep while driving at high speed, and the car crashes into the auxiliary guidance component 100, the pressure sensing probe 7 will be subjected to excessive impact force, and the first braking component 200, the second braking component 300, and the protective component 500 will start to operate simultaneously.
[0069] The first braking assembly 200 begins to brake the auxiliary guiding assembly 100. The dual-head electric cylinder 11 is activated, and the extension rod of the dual-head electric cylinder 11 drives the insert 12 to move towards the connecting rod of the wheel hub 6. The insert 12 is inserted into the connecting rod of the wheel hub 6, so that the wheel hub 6 cannot rotate. Then, the stationary anti-skid tire 9 assists in braking the car.
[0070] The second braking assembly 300 begins to perform the main braking operation on the car. The first motor 16 starts and drives the threaded rod 15 to rotate, causing the moving block 13 to move the brake plate 14 upward in the mounting slot of the fixed column 3, thereby lifting the car off the ramp block 2. The distance between each brake plate 14 is greater than the diameter of the car tire, and the brake plate 14 hooks onto the car chassis through multiple protrusions.
[0071] The protective component 500 starts operating to prevent the car from rolling over during a collision, falling over the top fixing block 4 from the highway bridge, and causing fatalities. The second motor 22 starts, driving the fixing rod 21 to rotate on the third fixing frame 20. This causes the second fixing frame 17, which is mounted on the third fixing frame 20, to rotate along with the fixing rod 21, moving the second elastic pad 19 above the top fixing block 4. Even if the car rolls over during a collision, it can be protected by the second elastic pad 19 and the third fixing frame 20. The second elastic pad 19 absorbs part of the impact force generated by the car collision, preventing the car from falling over the top fixing block 4 from the highway bridge.
[0072] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
