Description

Technical Field

[0001] This invention relates to the field of height restriction frames, and more particularly to a road surface manual / automatic lifting height restriction frame. Background Technology

[0002] Height restriction barriers are traffic facilities used to limit the height of vehicles. They are mainly used to protect infrastructure such as bridges and tunnels and prevent oversized vehicles from passing through. Height restriction barriers are divided into two types: fixed height restriction barriers and adjustable height restriction barriers. Fixed height restriction barriers cannot be adjusted, while adjustable height restriction barriers are divided into manual and electric types. Currently, most adjustable height restriction barriers use a single adjustment method, namely manual or electric. Each of these two adjustment methods has its advantages and disadvantages. Manual adjustment is more labor-intensive, while electric adjustment relies too much on the drive device. When the device malfunctions or there is a power outage, the height restriction barrier cannot be adjusted, which cannot meet the various needs of actual use.

[0003] This invention combines mechanical transmission with electric adjustment to give the height restriction frame the advantages of both manual and electric adjustment methods, and also gives it both mechanical and electronic height restriction warning capabilities. It provides a low-cost, high-efficiency high-resistance grounding fault location solution, which is particularly suitable for emergency construction scenarios without professional equipment support. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the current height adjustment method of height restriction frame cannot meet various needs during use.

[0005] The technical solution of the present invention: A road surface manual / automatic lifting height restriction frame includes a column, a lifting warning rod slidably connected to the inner side of the column, a sensor fixing rod fixedly connected to the bottom of the lifting warning rod, the sensor fixing rod slidably connected to the inner side of the column, a first steel wire rope fixedly connected to one end of the lifting warning rod, two fixed pulleys rotatably connected inside the column, the two fixed pulleys being arranged axially symmetrically, the first steel wire rope slidably connected to the outer side of the two fixed pulleys, a drive assembly provided on one side of the column, a second steel wire rope fixedly connected to the end of the lifting warning rod away from the first steel wire rope, a pulley group provided inside the column, the second steel wire rope slidably connected to the outer side of the pulley group, a warning light provided at the top of the lifting warning rod, and a warning assembly including a horizontal column fixedly connected to the top of the lifting warning rod provided inside the column.

[0007] Optionally, a damper is provided on one side of the sensor fixing rod, the damper is sleeved on one side of the support frame, and a transmission rod is fixedly connected inside the support frame.

[0008] Optionally, an unfolding rod is rotatably connected to one side of the column. One end of the unfolding rod is slidably connected to a connecting rod, and a warning cloth is fixedly connected to the inner side of the unfolding rod, with the warning cloth fixedly connected to one side of the column.

[0009] Optionally, a limiting post is fixedly connected to one side of the column, and a transmission plate is slidably connected to the outer side of the limiting post. A first spring is provided on one side of the transmission plate, and the first spring is fixedly connected to one side of the column.

[0010] Optionally, a cross-shaped limiting member is fixedly connected to one side of the column, a second spring is fixedly connected to the inner side of the cross-shaped limiting member, a transmission plug is slidably connected to the inner side of the cross-shaped limiting member, and the second spring is fixedly connected to the top of the transmission plug.

[0011] Optionally, a diamond-shaped retractable frame is provided on one side of the transmission insert, and sliding columns are provided on both sides of the diamond-shaped retractable frame. The two sliding columns are slidably connected to both sides of the cross-shaped limiting member, and the transmission plate is inserted into one side of the diamond-shaped retractable frame.

[0012] Optionally, a drum shaft is provided on the inner side of the drive assembly, and the second wire rope and the first wire rope are both wound on the outer side of the drum shaft.

[0013] Optionally, a gear mechanism is fixedly connected to one side of the drum shaft, and a reduction hand-cranked gear assembly is meshed on the outer side of the gear mechanism. The reduction hand-cranked gear assembly is rotatably connected to the inner side of the drive assembly.

[0014] Optionally, a motor is provided inside the drive assembly, a reduction mechanism is provided on one side of the motor, and a drive control unit is provided inside the drive assembly.

[0015] In summary, this application includes at least one of the following beneficial technical effects: This invention enables height restriction frames to simultaneously possess the advantages of manual and electric adjustment while avoiding their disadvantages. It achieves convenient single-person operation through a purely mechanical structure, and can also achieve continuous and precise adjustment using electric power, providing a height restriction function without energy dependence. It is suitable for scenarios with no power supply or low-frequency adjustment, such as rural roads, mine entrances, and temporary construction sections.

[0016] Furthermore, the warning components provide mechanical warnings to oncoming vehicles. When the height restriction barrier is powered off, the warning lights cannot provide timely warnings of exceeding the height limit. As the vehicle continues to approach, the excessive height portion of the vehicle will contact the rubber posts, causing the warning cloths on both sides to unfold to remind the driver that the vehicle exceeds the height limit. This can meet the various needs of the height restriction barrier in actual use.

[0017] In summary, this invention combines the advantages of manual and electric adjustment, enabling the height restriction frame to be easily operated by a single person through a purely mechanical structure, and also to be continuously and precisely adjusted electrically. Furthermore, it incorporates both electronic and mechanical over-height warnings, ensuring that the height restriction frame retains its functionality even after a power outage, thus meeting the needs of practical use.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Example 1: As Figures 1-8As shown, a road-mounted manual / automatic lifting height restriction frame includes a column 1. A lifting warning rod 2 is slidably connected to the inner side of the column 1. Both ends of the lifting warning rod 2 are rotatably connected to pulleys, and both pulleys are in contact with the column 1. A sensor fixing rod 3 is fixedly connected to the bottom of the lifting warning rod 2. A laser ranging module is installed at the top of the sensor fixing rod 3. The sensor fixing rod 3 is slidably connected to the inner side of the column 1. A first steel wire rope 4 is fixedly connected to one end of the lifting warning rod 2. Two fixed pulleys 5 are rotatably connected inside the column 1. The two fixed pulleys 5 are arranged axially symmetrically. The first steel wire rope 4 is slidably connected to the outside of the two fixed pulleys 5. A drive assembly 6 is installed on one side of the column 1. A second steel wire rope 7 is fixedly connected to the end of the lifting warning rod 2 away from the first steel wire rope 4. A pulley group 8 is installed inside the column 1. The second steel wire rope 7 is slidably connected to the outside of the pulley group 8. The top of the lifting warning rod 2... The unit is equipped with a warning light 9. A drum shaft 28 is provided inside the drive assembly 6. The second steel wire rope 7 and the first steel wire rope 4 are both wound around the outside of the drum shaft 28. A gear mechanism 29 is fixedly connected to one side of the drum shaft 28. A ratchet and pawl mechanism is provided on one side of the drum shaft 28 to limit the drum shaft 28 and prevent it from running away and reversing. A reduction hand-cranked gear assembly 30 is meshed on the outside of the gear mechanism 29. The reduction hand-cranked gear assembly 30 is rotatably connected to the inside of the drive assembly 6. A motor 31 is provided inside the drive assembly 6. A reduction mechanism 32 is provided on one side of the motor 31. A drive control unit 33 is provided inside the drive assembly 6. The drive control unit 33 is electrically connected to the laser ranging module, warning light 9, and motor 31 at the top of the sensor fixing rod 3. A warning assembly, including a horizontal column 12 fixedly connected to the top of the lifting warning rod 2, is provided inside the column 1.

[0026] In this embodiment, by engaging the gear at one end of the reduction mechanism 32 with the reduction hand-crank gear assembly 30, the power supply to the drive assembly 6 is turned on, and the target height limit is set by the drive control unit 33. After startup, the system automatically detects the laser ranging module and motor status. When there is no fault, the motor 31 rotates the drum shaft 28 through the gear transmission in the drive assembly 6 to wind up the first wire rope 4 and the second wire rope 7, thereby raising the lifting warning bar 2 to the correct height and automatically stopping and locking it. If the vehicle is detected to be too high, the warning light flashes, and the system pauses lifting. When the reduction mechanism 32 rotates the drum shaft 28 through the size transmission, the drum shaft 28 winds up the first wire rope 4 and the second wire rope 7. The first wire rope 4 and the second wire rope 7 are guided by the fixed pulley 5 and the pulley block 8, respectively, thereby enabling... The system can raise the lifting warning pole 2. After the power is disconnected, the drum shaft 28 can be rotated synchronously by manually turning the reduction hand-crank gear assembly 30, thereby winding up the first steel wire rope 4 and the second steel wire rope 7 and raising the lifting warning pole 2. At the same time, the ratchet and pawl mechanism on one side of the drum shaft 28 can prevent the drum shaft 28 from reversing and causing the lifting warning pole 2 to fall. It can also limit the drum shaft 28 to keep the lifting warning pole 2 at the current set height. This allows the height restriction frame to have the advantages of both manual and electric adjustment while avoiding their disadvantages. It can be operated by a single person through a purely mechanical structure, and can also be continuously and accurately adjusted by electric means. It is a height restriction function without energy dependence and is suitable for scenarios with no power supply or low frequency adjustment, such as rural roads, mine entrances, and temporary construction sections.

[0027] Example 2: A support frame 13 is rotatably connected to the outer side of the cross column 12. A rubber column 14 is fixedly connected to one side of the support frame 13. The rubber material of the rubber column 14 can prevent damage to the vehicle in the event of a collision. A damper 15 is provided on one side of the sensor fixing rod 3. The damper 15 reduces the rotation speed of the support frame 13 to prevent damage to the support frame 13 due to excessive movement. The damper 15 is sleeved on one side of the support frame 13. A transmission rod 16 is fixedly connected inside the support frame 13. An unfolding rod 17 is rotatably connected to one side of the column 1. A connecting rod 18 is slidably connected to one end of the unfolding rod 17. A warning cloth 19 is fixedly connected to the inner side of the unfolding rod 17. The warning cloth 19 is made of soft fabric and is fixedly connected to one side of the column 1. A limit post 20 is fixedly connected to one side of the column 1. A transmission plate is slidably connected to the outer side of the limit post 20. 21. A first spring 22 is provided on one side of the transmission plate 21. The first spring 22 is fixedly connected to one side of the column 1. A cross-shaped limiting member 23 is fixedly connected to one side of the column 1. A cross groove is provided on one side of the cross-shaped limiting member 23. A second spring 24 is fixedly connected to the inner side of the cross-shaped limiting member 23. A transmission plug 25 is slidably connected to the inner side of the cross-shaped limiting member 23. A pulley is provided at the bottom end of the transmission plug 25 to reduce friction when in contact with the connecting rod 18. The second spring 24 is fixedly connected to the top of the transmission plug 25. A diamond-shaped retractable frame 26 is provided on one side of the transmission plug 25. All nodes of the diamond-shaped retractable frame 26 are movably connected, so that the diamond-shaped retractable frame 26 can be extended and retracted. Sliding columns 27 are provided on both sides of the diamond-shaped retractable frame 26. The two sliding columns 27 are slidably connected to both sides of the cross-shaped limiting member 23. The transmission plate 21 is inserted into one side of the diamond-shaped retractable frame 26.

[0028] In this embodiment, the device can not only provide over-height warnings via the laser ranging module and warning light 9, but also provide mechanical warnings in the event of a power outage. When the driver of a tall vehicle, such as a truck carrying cargo, cannot determine whether it can pass, the vehicle will pass the pillar 1. It should be noted that the vehicle must proceed slowly at this time. The part of the vehicle exceeding the height limit will come into contact with the rubber pillar 14. The rubber material of the rubber pillar 14 can prevent damage to the vehicle upon collision. If the vehicle continues to move, it will push the support frame 13 to rotate. Since the rubber pillar 14 protrudes far from the lifting warning bar 2, it can prevent the vehicle from colliding with the lifting warning bar 2 or the sensor fixing rod 3, thereby achieving the purpose of early warning. When the support frame 13 rotates, it will drive the transmission rod 16 to move synchronously, and also affect the transmission plates on both sides. When 21 is pushed, the transmission plate 21 moves to one side, and the first spring 22 is stretched. The displacement of the transmission plate 21 will cause the diamond-shaped retractable frame 26 to retract. At the same time, the sliding columns 27 on both sides slide and move closer to each other inside the cross limit member 23, so that the transmission plug 25 rises and disengages from the inside of the connecting rod 18. At this time, the unfolding rod 17 flips outward under its own weight, and one end of the connecting rod 18 slides inside the unfolding rod 17. When one end of the connecting rod 18 slides to one end of the unfolding rod 17, it stops. At this time, the warning cloth 19 unfolds to reveal the warning sign, thereby warning the driver of the vehicle. In this way, the height restriction frame can provide a warning to passing vehicles in a purely mechanical way, so that the height restriction frame can still have a warning function when the power is off, in order to meet various needs in actual use.

[0029] The above specific embodiments are merely optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
