A 4G-based lifting warning device for highway middle strip

Abstract

The application belongs to the field of expressways, and particularly relates to a 4G-based expressway middle strip lifting warning device. The existing device cannot autonomously adjust the height, so workers need to manually adjust the height of the device, which is complicated, the expressway is long, the workload is large, and the device cannot adapt to double-lane problems. The following scheme is proposed, which comprises multiple groups of middle strips. Each group of middle strips comprises a main support seat and two auxiliary support seats. The two auxiliary support seats are respectively located on the two sides of the main support seat. A plurality of reinforcing railings are fixedly connected between the auxiliary support seat and the main support seat. In the application, the lifting rod drives the main warning board to vertically move upward to complete the adjustment of the height of the main warning board. The output shaft of the servo motor reverses to adjust the height of the side warning board. Meanwhile, the rubber pad is fully extruded. When the rectangular block drops to the lowest point, the braking state of the clamping block is contacted, and the two clamping blocks rebound. At this time, the rectangular block moves to the highest point, and the operation of moving the rectangular block upward can be completed.

Description

Technical Field

[0001] This invention relates to the field of highway technology, and in particular to a 4G-based lifting warning device for highway median strips. Background Technology

[0002] Transportation refers to the industry engaged in the transport of passengers and goods, as well as the transmission of language and text, encompassing both transportation and postal services. It belongs to the tertiary sector of the national economy. Transportation includes five modes: railway, highway, waterway, air, and pipeline. Postal services include postal services and telecommunications. A highway is defined as "a road capable of accommodating an average daily traffic volume of over 25,000 passenger vehicles, dedicated to high-speed, lane-separated travel for automobiles, with fully controlled access."

[0003] Highways are generally equipped with warning devices, but existing warning devices still have the following shortcomings in use:

[0004] 1. The height cannot be adjusted independently, which requires workers to manually adjust the height of the device, making the operation cumbersome, and the workload is large due to the long distance on the highway.

[0005] 2. It cannot be adapted to two-lane roads and is generally located on one side of the road, making it inconvenient to use. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to automatically adjust the height, which necessitates manual adjustment by workers, resulting in cumbersome operation, long highway routes, heavy workload, inability to adapt to dual lanes, and inconvenience due to their typical location on one side of the highway. Therefore, this invention proposes a 4G-based lifting warning device for highway median strips.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A 4G-based lifting warning device for median strips on highways includes multiple median strips, each median strip comprising a main support base and two auxiliary support bases.

[0009] The two auxiliary support seats are located on both sides of the main support seat. Multiple reinforcing railings are fixedly connected between the auxiliary support seats and the main support seat. A lifting rod slides through the top of the main support seat. A main warning plate is fixedly connected to the top of the lifting rod. A fixing plate is fixedly connected inside the main support seat. A lifting assembly for controlling the lifting of the lifting rod is installed inside the fixing plate.

[0010] Both sides of the main support base are provided with through holes, and a connecting block slides through the inside of the through holes. A side warning plate is fixedly connected to one end of the connecting block. The same sliding plate is slidably connected between the inner walls of the two sides of the main support base. A fixing component for fixing the height of the side warning plate is provided at the bottom of the sliding plate.

[0011] The sliding plate is equipped with a release component for releasing the side warning plate brake.

[0012] In one possible design, the lifting assembly includes a servo motor fixedly connected to the bottom of a fixed plate. The output shaft of the servo motor rotatably passes through the fixed plate and is fixedly connected to a second gear. A first gear is rotatably connected to the top of the fixed plate. The first gear meshes with the second gear. A screw rod passes through the internal thread of the first gear. The bottom of the screw rod passes through the fixed plate. The top of the screw rod is rotatably connected to the bottom of the lifting rod.

[0013] In one possible design, the fixing component includes a rectangular block fixedly connected to the bottom of the sliding plate. A first groove is formed on both sides of the rectangular block, and a locking block slides through the interior of each first groove. One end of the locking block is fixedly connected to the same first spring between it and one inner wall of the first groove. Rectangular plates are fixedly connected to the inner walls of both sides of the main support base. Multiple first slots are formed on one side of each rectangular plate, and these slots engage with the locking blocks. A side plate is fixedly connected to the bottom of one side of the rectangular plate, and the side plate cooperates with the locking blocks.

[0014] In one possible design, the release assembly includes two second grooves formed inside the sliding plate, with a limiting block sliding through the interior of the second groove. An L-shaped locking rod is fixedly connected to the bottom of the limiting block, and the same second spring is fixedly connected between the bottom of the limiting block and the bottom inner wall of the second groove. The second spring is sleeved on the L-shaped locking rod, and a second locking groove is formed at the bottom of the locking block to engage with the L-shaped locking rod.

[0015] In one possible design, both the main support and the auxiliary support are fixedly connected to a fixed base at their bottom, and the fixed base has multiple drainage grooves inside.

[0016] In one possible design, a vertical rod is fixedly connected to the bottom of the connecting block, the bottom of the vertical rod is fixedly connected to the top of the sliding plate, and a rubber pad is fixedly connected to the bottom of the connecting block, the rubber pad being located inside the through hole.

[0017] In one possible design, a rain shield is fixedly connected to the top of the auxiliary support.

[0018] In one possible design, two symmetrically arranged fixing strips are fixedly connected to the inner wall of one side of the main support base, and the fixing strips are used in conjunction with the limiting block.

[0019] In this application, when it is necessary to adjust the height of the main warning plate, the servo motor can be started. The output shaft of the servo motor drives the second gear to rotate, the second gear drives the first gear to rotate, the first gear drives the screw to move vertically upward, the screw drives the lifting rod to move vertically upward, and the lifting rod drives the main warning plate to move vertically upward, thereby completing the adjustment of the height of the main warning plate.

[0020] When it is necessary to lower the height of the side warning plate, the servo motor can be started, causing the output shaft of the servo motor to reverse, the screw to move vertically downward, the screw to drive the sliding plate to move vertically downward, the sliding plate to drive the rectangular block and the vertical rod to move vertically downward, the vertical rod to drive the connecting block to move vertically downward, the connecting block to drive the side warning plate to move vertically downward, and the height of the side warning plate can be adjusted. After the adjustment is completed, the screw can be reset.

[0021] At the same time, the locking block continuously engages with the first locking slot to prevent the rectangular block from falling. When the rectangular block needs to move upward, it can be moved vertically downward to the bottom. At this time, the locking block contacts the side plate and is completely retracted into the inside of the first groove. At this time, the L-shaped locking rod engages with the second locking slot, so that the locking block cannot pop out.

[0022] At the same time, the rubber pad is fully compressed. When the rectangular block reaches its lowest point, the rubber pad drives the rectangular block to reset. At this time, the top of the two limit blocks contacts the bottom of the fixing strip. The limit blocks retract into the interior of the second groove. The second groove drives the L-shaped locking rod to move vertically downward. The L-shaped locking rod no longer engages with the second locking groove. At this time, the braking state of the locking block is engaged, and the two locking blocks rebound. At this time, the rectangular block moves to the highest point, and the operation of moving the rectangular block upward can be completed.

[0023] In this invention, a 4G-based highway median strip lifting warning device can achieve the effect of controlling the lifting of the lifting pole through a lifting assembly;

[0024] In this invention, the lifting warning device for the median strip on highways based on 4G can achieve the effect of fixing the height of the side warning plate through a fixing component;

[0025] In this invention, the servo motor is started, and the lifting rod drives the main warning plate to move vertically upward, thus adjusting the height of the main warning plate. The output shaft of the servo motor reverses, and the connecting block drives the side warning plate to move vertically downward, adjusting the height of the side warning plate. At the same time, the rubber pad is fully compressed. When the rectangular block reaches the lowest point, the braking state of the locking block is engaged, and the two locking blocks rebound. At this time, the rectangular block moves to the highest point, thus completing the operation of moving the rectangular block upward. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Example 1

[0035] Reference Figure 1-6 A 4G-based lifting warning device for median strips on highways, used in the highway field, includes: multiple median strips, each median strip including a main support 2 and two auxiliary support 8.

[0036] Two auxiliary support bases 8 are located on both sides of the main support base 2. Multiple reinforcing railings 6 are fixedly connected between the auxiliary support bases 8 and the main support base 2. A lifting rod 4 slides through the top of the main support base 2. A main warning plate 5 is fixedly connected to the top of the lifting rod 4. A fixing plate 10 is fixedly connected inside the main support base 2. The fixing plate 10 contains a lifting assembly for controlling the lifting of the lifting rod 4. The lifting assembly includes a servo motor 15 fixedly connected to the bottom of the fixing plate 10, and a 4G DTU module (Yinerda Air724) powered by DC power. This switch can be remotely controlled to turn on and off, driving the motor control module (the Air724 is connected to the drive motor control module, which in turn is connected to the servo motor 15), achieving remote control. The purpose of controlling the servo motor 15 for lifting is that the output shaft of the servo motor 15 rotates through the fixed plate 10 and is fixedly connected to the second gear 14. The top of the fixed plate 10 is rotatably connected to the first gear 13, which meshes with the second gear 14. The internal thread of the first gear 13 passes through the screw 9, the bottom of the screw 9 passes through the fixed plate 10, and the top of the screw 9 is rotatably connected to the bottom of the lifting rod 4. When it is necessary to adjust the height of the main warning plate 5, the servo motor 15 can be started. The output shaft of the servo motor 15 drives the second gear 14 to rotate, the second gear 14 drives the first gear 13 to rotate, the first gear 13 drives the screw 9 to move vertically upward, the screw 9 drives the lifting rod 4 to move vertically upward, and the lifting rod 4 drives the main warning plate 5 to move vertically upward, thus completing the adjustment of the height of the main warning plate 5.

[0037] Both sides of the main support base 2 are provided with through holes 32, through which a connecting block 16 slides. One end of the connecting block 16 is fixedly connected to a side warning plate 3. The inner walls of both sides of the main support base 2 are slidably connected to the same sliding plate 11. The bottom of the sliding plate 11 is provided with a fixing component for fixing the height of the side warning plate 3. The fixing component includes a rectangular block 12 fixedly connected to the bottom of the sliding plate 11. Both sides of the rectangular block 12 are provided with first grooves 25. A locking block 23 slides through the inside of the first groove 25. One end of the locking block 23 is fixedly connected to the same first spring 24 between one side of the inner wall of the first groove 25. Both sides of the inner walls of the main support base 2 are fixedly connected to rectangular plates 21. One side of the rectangular plate 21 is provided with multiple first slots 20. The first slots 20 engage with the locking blocks 23. A side plate 19 is fixedly connected to the bottom of one side of the rectangular plate 21. When used in conjunction with the locking block 23, the servo motor 15 can be activated to reverse the output shaft of the servo motor 15 when the height of the side warning plate 3 needs to be lowered. The screw 9 moves vertically downward, which in turn drives the sliding plate 11 to move vertically downward. The sliding plate 11 drives the rectangular block 12 and the vertical rod 17 to move vertically downward. The vertical rod 17 drives the connecting block 16 to move vertically downward. The connecting block 16 drives the side warning plate 3 to move vertically downward, thus adjusting the height of the side warning plate 3. After the adjustment is completed, the screw 9 can be reset. At the same time, the locking block 23 continuously engages with the first slot 20 to prevent the rectangular block 12 from falling. When the rectangular block 12 needs to be moved upward, it can be moved vertically downward to the bottom. At this time, the locking block 23 contacts the side plate 19 and is completely retracted into the first groove 25. At this time, the L-shaped locking rod 26 engages with the second slot 30, preventing the locking block 23 from popping out.

[0038] The sliding plate 11 is internally equipped with a release assembly for releasing the brake on the side warning plate 3. The release assembly includes two second grooves 27 formed inside the sliding plate 11. A limiting block 29 slides through the interior of each second groove 27. An L-shaped locking rod 26 is fixedly connected to the bottom of the limiting block 29. A second spring 28 is fixedly connected between the bottom of the limiting block 29 and the inner bottom wall of the second groove 27. The second spring 28 is sleeved on the L-shaped locking rod 26. A second slot 30 is formed at the bottom of the locking block 23 to engage with the L-shaped locking rod 26. When the rubber pad 31 is fully compressed, when the rectangular block 12 reaches its lowest point, the rubber pad 31 drives the rectangular block 12 to reset. At this time, the tops of the two limiting blocks 29 contact the bottom of the fixing strip 18, and the limiting blocks 29 retract into the interior of the second groove 27. The second groove 27 drives the L-shaped locking rod 26 to move vertically downward. The L-shaped locking rod 26 no longer engages with the second locking groove 30. At this time, the braking state of the locking block 23 is engaged, and the two locking blocks 23 rebound. At this time, the rectangular block 12 moves to the highest point, and the operation of moving the rectangular block 12 upward can be completed.
