Description

Technical Field

[0001] The invention relates to the technical field of road facilities, and in particular to a multifunctional road height limiting device. Background Art

[0002] Highway height limit devices refer to equipment used to mark and limit the height of vehicle passage. They are installed at the entrances of highways, bridges or other roads. The main function of these devices is to ensure that vehicles can pass safely and avoid traffic accidents caused by improper height restrictions.

[0003] Although the height limit device in the prior art ensures driving safety to a certain extent, vehicle collisions still occur because the height limit warning is not obvious. When a vehicle collides with the height limit device, it is usually necessary to replace the entire height limit device, wasting manpower and material resources.

[0004] Therefore, in view of the above problems, a multifunctional road height limiting device is proposed to solve the above problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention develops a multifunctional road height limiting device, which can give advance warning to over-height vehicles and reduce the collision damage of vehicles to the height limiting device.

[0006] The technical solution to the technical problem solved by the present invention is: a multifunctional road height limiting device, including a concrete foundation, the concrete foundations are symmetrically arranged on both sides of the road, mounting frames are arranged on the concrete foundations, the symmetrically arranged mounting frames are connected by connecting frames, the connecting frames are provided with a warning part, the concrete foundation is connected to support rods, the support rods are vertically arranged between the concrete foundations, the lower ends of the symmetrically arranged support rods are connected through the mounting foundation, the mounting foundation is buried under the road, the upper ends of the support rods are provided with a height limiting part, the height limiting part includes a height limiting rod, and the height limiting rod is lower than the connecting frame.

[0007] A connecting frame is arranged between the mounting frames, and a warning part is arranged on the connecting frame. The warning part is used to give early warning to the vehicle to attract the driver's attention and reduce the number of over-height vehicles entering the height-restricted area. When the driver does not notice the warning, the over-height vehicle is further blocked by the height-limiting pole of the height-limiting part to avoid traffic accidents caused by the over-height. The surface of the height-limiting pole is coated with reflective material to enhance nighttime recognition. The height-limiting pole is lower than the connecting frame to avoid damage to the connecting frame in the event of a collision, thereby protecting the connecting frame and the warning part on the connecting frame.

[0008] Preferably, the warning unit includes a warning sign, a flashlight, a battery, an auxiliary pole, an infrared beamer and an alarm. The warning sign and the battery are arranged on the vehicle-facing direction of the connecting frame, the flashlight is arranged on the outside of the warning sign, and auxiliary poles are symmetrically arranged on both sides of the road in front of the mounting frame. An infrared beamer is arranged on the auxiliary poles. The infrared beamer is electrically connected to the alarm, and the battery is electrically connected to the flashlight, the infrared beamer and the alarm, respectively.

[0009] The flashing lights are always on day and night, and oncoming vehicles are warned by flashing lights and warning signs. When a vehicle approaches, the infrared beamer detects an over-height vehicle and immediately triggers the alarm to sound a warning, reminding the driver to stop. The battery ensures that the system can still work normally in the event of a power outage. The auxiliary rod provides firm support, ensuring that the entire system is stable and reliable, effectively preventing traffic accidents.

[0010] Preferably, the warning unit also includes a monitoring camera and a signal transmitter. Multiple monitoring cameras are arranged on both sides of the connecting frame. The monitoring camera is electrically connected to the signal transmitter, the monitoring camera is electrically connected to the battery, and the signal transmitter is electrically connected to the battery.

[0011] The surveillance camera records the road conditions in real time, and the signal transmitter transmits the data to the monitoring center for remote monitoring and management, ensuring the efficient operation of the system and improving the road safety factor.

[0012] Preferably, a support platform is arranged on the side of the connecting frame away from the warning sign, a plurality of reinforcing ribs are arranged between the support platform and the connecting frame, a solar panel is arranged on the support platform, and the solar panel is electrically connected to the battery.

[0013] Solar panels absorb sunlight and convert it into electrical energy, which provides continuous power to the batteries, ensuring stable operation of all components and guaranteeing power supply even in rainy weather, further improving system reliability and road safety.

[0014] Preferably, the height limiting part also includes a card plate, an installation groove, a positioning hole, a mounting platform, a rotating shaft and a connecting platform. The connecting platform is arranged at the upper end of the support rod, the rotating shaft is arranged on the connecting platform, the mounting platform is rotatably arranged on the rotating shaft, the mounting platform is horizontally arranged with the installation groove, the card plate is clamped in the installation groove, and multiple positioning holes are arranged between the card plate and the mounting groove. The card plate and the mounting groove can be connected by a plug rod through the multiple positioning holes, the card plate is connected to the height limiting pole, and the symmetrically arranged height limiting poles are arranged horizontally.

[0015] The symmetrically arranged height limit poles are rotatably arranged on the connecting platform. When the driver of an over-height vehicle negligently drives and collides with the height limit poles, the height limit poles are rotated by force, which reduces the occurrence of the height limit poles being broken and reduces the replacement of the height limit poles. The height limit poles are installed through the clamping plate and the mounting groove, which is convenient for the subsequent replacement of the height limit poles.

[0016] Preferably, the height limiting part also includes a reset spring, a first connecting head and a second connecting head. The first connecting head is symmetrically arranged on both sides of the mounting platform, and the second connecting head is symmetrically arranged on both sides of the connecting platform. The two ends of the reset spring are respectively connected to the first connecting head and the second connecting head, and a protective structure is arranged between the connecting platform and the mounting platform.

[0017] The two ends of the return spring are connected to the first connecting head and the second connecting head. When the height limit rod is hit and rotates, the return spring absorbs part of the energy to prevent the height limit rod from rotating violently and colliding with the mounting frame, thereby protecting the mounting frame and having a certain blocking effect on the vehicle.

[0018] Preferably, the protective structure includes a limit groove, a guide hole, a guide rod, a compression spring, a retaining ring, a mounting block, a limit plate, an inclined surface and a guide groove. The mounting block is arranged on the mounting platform, and a guide groove is arranged in the mounting block. A guide hole is arranged above the guide groove, and a guide rod is slidably connected in the guide hole. A retaining ring is arranged at the upper end of the guide rod, and a limit plate is arranged at the lower end of the guide rod. The limit plate is slidably connected in the guide groove, and an inclined surface is arranged at the lower end of the limit plate, and the inclined surface faces the direction in which the height limit rod is rotated by impact. A compression spring is arranged on the guide rod, and both ends of the compression spring are respectively connected to the limit plate and the inner wall of the guide groove. A plurality of limit grooves are arranged on the connecting platform, and the lower end of the limit plate is slidably connected in the limit groove.

[0019] When the height limit rod is hit and rotates, the inclined surface guides the limit plate to slide, and the limit plate rotates accordingly. During the rotation process, the limit plate receives the elastic force of the compression spring and is inserted into different limit grooves. When the impact stops and the driver reverses, the height limit rod is reset and rotated by the reset spring. At this time, the limit plate and the limit groove cooperate with each other to prevent the height limit rod from rotating further, reducing the subsequent collision between the height limit rod and the vehicle during the reset rotation process, reducing vehicle losses, and facilitating the vehicle to reverse.

[0020] Preferably, the protective structure also includes an installation cavity, a slide groove, a connecting rod, a slider, a connecting bolt and a tension spring. The installation cavity is arranged on the support rod, and the connecting rod is slidably connected in the installation cavity. The connecting rod is connected to the connecting platform. Slide grooves are symmetrically arranged on both sides of the installation cavity, and the slider is slidably connected in the slide groove. The slider is arranged on the connecting rod through a plurality of connecting bolts. A tension spring is arranged in the installation cavity, and the two ends of the tension spring are respectively connected to the connecting rod and the support rod.

[0021] The connecting platform is inserted into the installation cavity through a connecting rod, and the connecting rod is fixed by a tension spring, so that the connecting platform and the connecting rod can move along the installation cavity when impacted, reducing the impact on the support rod. When not impacted, the tension spring makes the connecting platform fit with the top of the support rod to prevent inaccurate height limit.

[0022] Preferably, a clamp is provided on the concrete foundation, the clamp is connected to the support rod, a support plate is provided on the connecting frame, a clamp block is symmetrically provided on the side of the support plate away from the oncoming direction, the clamp block is overlapped in the clamp ring, the clamp ring is provided on the support block, and the support block is provided at a place where the height limit rod is away from the support rod.

[0023] The clamp fits the support rod to the concrete foundation to prevent the support rod from tipping over. The height limit rod is connected to the support plate of the connecting frame through the clamp ring. The height limit rod is hoisted to prevent the height limit rod from bending due to gravity during long-term use and affecting the height limit accuracy. At the same time, when the height limit rod is hit, the block and the clamp ring fall off to prevent the support plate from being impacted.

[0024] The effects provided in the content of the invention are only the effects of the embodiments, rather than all the effects of the invention. The above technical solution has the following advantages or beneficial effects: A connecting frame is arranged between the mounting frames, and a warning part is arranged on the connecting frame. The warning part is used to give early warning to the vehicle, attract the attention of the driver, and reduce the number of over-height vehicles entering the height-restricted area. When the driver fails to notice the warning, the over-height vehicle is further blocked by the height-limiting pole of the height-limiting part to avoid traffic accidents caused by over-height. The surface of the height-limiting pole is coated with reflective material to enhance nighttime recognition. The height-limiting pole is lower than the connecting frame to avoid damage to the connecting frame in the event of a collision, thereby protecting the connecting frame and the warning part on the connecting frame. The flashing lights are always on day and night, and the flashing lights and warning signs are used to warn oncoming vehicles. When a vehicle approaches, the infrared beam detector detects the over-height vehicle and immediately triggers the alarm to sound a warning to remind the driver to stop. The battery ensures that the system can still work normally in the event of a power outage. The auxiliary rod provides a stable support to ensure that the entire system is stable and reliable, effectively preventing traffic accidents. The symmetrically arranged height limit poles are rotatably arranged on the connecting platform. When the driver of an over-height vehicle carelessly collides with the height limit pole, the height limit pole is rotated by force, which reduces the possibility of the height limit pole being broken and the replacement of the height limit pole. The height limit pole is installed through the card plate and the installation slot, which is convenient for the subsequent replacement of the height limit pole. The two ends of the return spring are connected to the first connecting head and the second connecting head. When the height limit rod is hit and rotates, the return spring absorbs part of the energy to prevent the height limit rod from rotating violently and colliding with the mounting frame, thereby protecting the mounting frame and having a certain blocking effect on the vehicle.

The flashlight 8 is always on day and night, and the flashlight 8 and the warning sign 7 are used to warn the approaching vehicles. When the vehicle approaches, the infrared radio 11 detects the over-height vehicle and immediately triggers the alarm 12 to emit a warning sound to remind the driver to stop. The battery 9 ensures that the system can still work normally in the case of power failure. The auxiliary rods 10 provide a stable support to ensure that the entire system is stable and reliable, effectively preventing traffic accidents.

[0037] The warning unit also includes a monitoring camera 13 and a signal transmitter 14. Multiple monitoring cameras 13 are arranged on both sides of the connecting frame 3. The monitoring camera 13 is electrically connected to the signal transmitter 14. The monitoring camera 13 is electrically connected to the battery 9. The signal transmitter 14 is electrically connected to the battery 9. The monitoring camera 13 records the road conditions in real time, and the signal transmitter 14 transmits the data to the monitoring center, which is convenient for remote monitoring and management, ensuring the efficient operation of the system and improving the road safety factor.

[0038] A support platform 15 is provided on the side of the connecting frame 3 away from the warning sign 7, a plurality of reinforcing ribs 16 are provided between the support platform 15 and the connecting frame 3, a solar panel 17 is provided on the support platform 15, and the solar panel 17 is electrically connected to the storage battery 9.

[0039] The height limiting part also includes a card plate 18, a mounting groove 19, a positioning hole 20, a mounting platform 21, a rotating shaft 22 and a connecting platform 23. The connecting platform 23 is arranged at the upper end of the support rod 4, the rotating shaft 22 is arranged on the connecting platform 23, the mounting platform 21 is rotatably arranged on the rotating shaft 22, the mounting platform 21 is horizontally arranged with the mounting groove 19, the card plate 18 is clamped in the mounting groove 19, the card plate 18 and the mounting groove 19 are both provided with a plurality of positioning holes 20, the card plate 18 and the mounting groove 19 can be connected by a plurality of positioning holes 20, the card plate 18 is connected to the height limiting rod 6, and the symmetrically arranged height limiting rod 6 is horizontally arranged. The symmetrically arranged height limiting rod 6 is rotatably arranged on the connecting platform 23. When the driver of the super-high vehicle negligently drives and collides with the height limiting rod 6, the height limiting rod 6 is rotated by force, which reduces the occurrence of the height limiting rod 6 being broken and reduces the replacement of the height limiting rod 6. The height limiting rod 6 is installed through the card plate 18 and the mounting groove 19, which is convenient for the subsequent replacement of the height limiting rod 6.

[0040] The height limiting part also includes a return spring 24, a first connector 25 and a second connector 26. The first connector 25 is symmetrically arranged on both sides of the mounting platform 21, and the second connector 26 is symmetrically arranged on both sides of the connecting platform 23. The two ends of the return spring 24 are respectively connected to the first connector 25 and the second connector 26, and a protective structure is arranged between the connecting platform 23 and the mounting platform 21. The two ends of the return spring 24 are connected to the first connector 25 and the second connector 26. When the height limiting rod 6 is hit and rotates, the return spring 24 absorbs part of the energy to prevent the height limiting rod 6 from being hit and violently rotating to collide with the mounting frame 2, thereby protecting the mounting frame 2 and having a certain blocking effect on the vehicle.

[0041] The protection structure includes a limit groove 27, a guide hole 28, a guide rod 29, a compression spring 30, a retaining ring, a mounting block 32, a limit plate 33, an inclined surface 34 and a guide groove 35.

The limit plate 33 is slidably connected in the guide groove 35, and an inclined surface 34 is arranged at the lower end of the guide rod 29. The inclined surface 34 faces the direction in which the height limit rod 6 is hit and rotated. The guide rod 29 is sleeved with a compression spring 30, and the two ends of the compression spring 30 are respectively connected to the limit plate 33 and the inner wall of the guide groove 35. A plurality of limit grooves 27 are arranged on the connecting platform 23, and the lower end of the limit plate 33 is slidably connected in the limit groove 27. When the height limit rod 6 is hit and rotates, the inclined surface 34 guides the limiting plate 33 to slide, and the limiting plate 33 rotates accordingly. During the rotation, the limiting plate 33 receives the elastic force of the compression spring 30 and is inserted into different limiting grooves 27. When the impact stops and the driver reverses, the height limit rod 6 is reset and rotated by the reset spring 24. At this time, the limiting plate 33 and the limiting groove 27 cooperate with each other to prevent the height limit rod 6 from rotating further, thereby reducing the subsequent collision between the height limit rod 6 and the vehicle during the reset and rotation process, reducing vehicle losses, and facilitating the vehicle to reverse.

[0042] The protection structure also includes an installation cavity 36, a slide groove 37, a connecting rod 38, a slider 39, a connecting bolt 40 and a tension spring 41.

The connecting rod 38 is connected to the connecting platform 23. The slide grooves 37 are symmetrically arranged on both sides of the installation cavity 36, and the slider 39 is slidably connected in the slide groove 37. The slider 39 is arranged on the connecting rod 38 through a plurality of connecting bolts 40. A tension spring 41 is arranged in the installation cavity 36, and the two ends of the tension spring 41 are respectively connected to the connecting rod 38 and the support rod 4. The connecting platform 23 is inserted into the installation cavity 36 through the connecting rod 38, and the connecting rod 38 is fixed by the tension spring 41, so that the connecting platform 23 and the connecting rod 38 can move along the installation cavity 36 when impacted, reducing the impact on the support rod 4. When not impacted, the tension spring 41 makes the connecting platform 23 fit the top of the support rod 4 to prevent inaccurate height limit.

[0043] The concrete foundation 1 is provided with a clamp 42, which is connected to the support rod 4. The connecting frame 3 is provided with a support plate 43. A clamp block 44 is symmetrically provided on one side of the support plate 43 away from the vehicle oncoming direction. The clamp block 44 is overlapped in the clamp ring 45. The clamp ring 45 is provided on the support block 46. The support block 46 is provided at the place where the height limit rod 6 is away from the support rod 4. The clamp 42 fits the support rod 4 with the concrete foundation 1 to prevent the support rod 4 from tipping over. The height limit rod 6 is connected to the support plate 43 of the connecting frame 3 through the clamp ring 45. The height limit rod 6 is hoisted to prevent the height limit rod 6 from being bent by gravity due to long-term use and affecting the height limit accuracy. At the same time, when the height limit rod 6 is hit, the clamp block 44 and the clamp ring 45 fall off to prevent the support plate 43 from being hit.

[0044] Working principle: When the car is driving, it first passes through the infrared radiometer 11 to detect the height. When it exceeds the height limit, the alarm 12 sounds an alarm to remind the driver. At the same time, the monitoring camera 13 continues to shoot the car image and transmit it. When the driver ignores the alarm, the vehicle continues to move forward and collides with the height limit pole 6. The height limit pole 6 rotates due to the impact, and the return spring 24 twists to absorb part of the impact energy. After the vehicle collides, the driver reverses, and the protective structure prevents the height limit pole 6 from rebounding, making it convenient for the vehicle to reverse and break away from the height limit pole 6.

[0045] Although the above describes the specific implementation mode of the invention in conjunction with the drawings, it is not intended to limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
