Multi-lane suspended warning device

Abstract

A multi-lane suspended warning device forms a box chamber through a support box and a crossbeam box, which is equipped with N groups of tracks and N sets of steel cable drive modules. Each steel cable drive module drives a suspended traffic sign to move laterally to adjust the suspension position. In this way, when there is a problem of multiple lanes being occupied, the device can suspend the sign in front of each occupied lane. The movement of the sign is located at high altitude, no longer occupying road space, and does not affect road driving. The operation and drive devices are both located on the support box on the side of the road, and people do not need to enter the middle of the road for operation, which is safe.

Description

Technical Field

[0001] The present invention relates to the technical field of highway traffic guidance and emergency handling, and in particular to a multi-lane suspended warning device. Background Art

[0002] There are thousands of roads, but safety is the most important. For highways and expressways, since there are many people and vehicles on the road and their skills vary, road safety is even more important. In the existing technology, when a vehicle breaks down and stops on the road, it is usually prompted by the placement of onboard warning signs to alert the vehicle ( Figure 9 On-vehicle warning signs should be placed a certain distance behind the vehicle, generally recommended to be around 50-100 meters. The specific distance can be adjusted based on the vehicle's speed and surrounding environment. Placing warning signs on high-speed roads or highways is also a dangerous activity, with a high risk of secondary injuries to the person placing them. To address this issue, Chinese invention patent application number 201811160881.8 discloses a device for preventing secondary accidents on roads. The device is installed on fixed roadside structures. The device includes a warning cone mechanism, a deployment mechanism connected to the cone mechanism to keep it away from roadside fixed structures, a drive mechanism for driving the deployment mechanism to expand and retract, and a control mechanism for controlling the start and stop of the drive mechanism. The device can automatically and timely deploy the cones to prevent secondary accidents. By controlling the device in a combined manner, it can divert other vehicles from the accident scene, improving safety. The device's deployment mechanism, when extended, lies on the road surface. While it can move the cones from the roadside to the middle of the road, the road surface occupied by the deployment mechanism still affects traffic efficiency, creating new problems.

[0003] In addition, as for vehicle-mounted warning signs, there is generally only one for each vehicle. When multiple lanes are occupied, multi-lane prompts cannot be provided. The device in the above-mentioned invention patent can only provide one multi-lane prompt and cannot provide multi-lane prompts. Summary of the Invention

[0004] In order to solve the problem of prompting when multiple vehicles are occupied as mentioned in the background art and to achieve prompts and warnings for multiple lanes, the present invention proposes a multi-lane suspended warning device.

[0005] The technical solution adopted by the present invention is: a multi-lane suspended warning device, including vertically arranged support boxes on both sides and a crossbeam box located above the two support boxes, which is characterized in that: the width of the support box matches the width of the crossbeam box, and the support box is connected to the inside of the crossbeam box.

[0006] N groups of tracks are provided at the lower part of the crossbeam box body, and N sets of steel cable drive modules are provided in the support box body and the crossbeam box body, which are respectively installed corresponding to the N groups of tracks; each set of steel cable drive modules includes inner and outer double-layer steel cables arranged in an N shape, and a steering wheel is provided at the turning point of the steel cable. A slide is fixedly connected to the lower layer of the transverse section of the steel cable, and the slide is installed on a group of tracks. A traffic sign is installed at the lower part of the slide through a suspension rod; in this way, the sign is located at a high altitude and does not occupy the road surface.

[0007] The vertical section of each set of cables is located within the support box. A drive mechanism is installed at the bottom of the support box to drive the cables back and forth. The cables then drive the slides back and forth on the track, with N ≥ 3. Multiple signage signs are located on different tracks, each indicating a different lane, creating a multi-lane warning effect.

[0008] Preferably, the drive device includes an axle for a steel cable steering wheel at the lower end of the vertical section. The axle is fixedly mounted to the steering wheel, with both ends of the axle extending out of the two side walls of the support box. The ends of the axle are mounted on the two side walls via bearings or sleeves. Multiple indicator signs are located on different tracks, each indicating a different lane, thereby achieving a multi-lane warning effect. A docking end is provided at the outer end of the axle; the docking end can be either square or triangular, and the foundation pit is non-circular.

[0009] The axles of each cable drive module are staggered and positioned at different heights. The device also features an operating crank that is detachably connected to the shaft's docking end. The crank has corresponding square or triangular holes that match to achieve rocking.

[0010] Preferably, the driving device further comprises a driving motor located in the crossbeam box or the support box, and the driving motor is connected to one of the steering wheels for transmission.

[0011] Preferably, the cable deflector wheel at the lower end of the vertical section is a double-grooved wheel, one groove of which is used to hang the cable, and the other groove is directly connected to the drive motor through the drive cable. When the drive motor rotates, the double-grooved wheel rotates, and then drives the cable above and the slide to move.

[0013] Preferably, each track set includes two symmetrically mounted L-shaped tracks, each track including vertical side panels and a transverse bottom panel. The width of the slide plate matches the distance between the inner surfaces of the two vertical side panels of each track set, and is used to control the slide plate from moving between the tracks and prevent it from detaching from the tracks. The movement of the steel cable drives the slide plate to slide on the upper surface of the track bottom panel, thereby driving the movement of the suspended traffic sign. The lower layer of the steel cable's transverse section is located on the upper surface of the slide plate and is fixedly connected to the slide plate via a pressure plate. The lower layer of the steel cable's transverse section is located in the middle of the track set and arranged parallel to the tracks.

Each steel cable drive module drives a suspended traffic sign to move laterally to adjust the suspension position. In this way, when there is a problem of multiple lanes being occupied, the device can suspend the sign in front of each occupied lane. The movement of the sign is located at high altitude, no longer occupying road space, and does not affect road driving. The operation and drive devices are both located on the support box on the side of the road, and people do not need to enter the middle of the road for operation, which is safe.

[0031] Example 1: See Figure 1-8The figure shows a multi-lane suspended warning device, comprising two vertically arranged support boxes and a crossbeam box located above the two support boxes. The device is characterized in that the width of the support boxes matches the width of the crossbeam box, and the support boxes are internally connected to the crossbeam box. N sets of tracks are located below the crossbeam box, and N sets of steel cable drive modules are installed within the support and crossbeam boxes, corresponding to the N sets of tracks. Each set of steel cable drive modules includes inner and outer double-layer steel cables arranged in an N-shape. Steering wheels are installed at the bends of the cables. A slide is fixedly connected to the lower layer of the transverse section of the cables, which is mounted on a set of tracks. A traffic sign is mounted on the lower portion of the slide via a suspension rod. The sign is thus located high in the air, not occupying the road surface. The vertical section of each set of steel cables is located within the support box. A drive device is installed below the support box to drive the cables back and forth, and the cables drive the slide back and forth on the tracks. N ≥ 3. Multiple signboards are located on different tracks, each indicating a different lane, thus achieving a multi-lane warning effect.

[0032] The drive device includes an axle of a steel cable steering wheel at the lower end of the vertical section. The axle is fixedly mounted to the steering wheel, with both ends of the axle extending out of the two side walls of the support box. Both ends of the axle are mounted on the two side walls via bearings or bushings. A docking end is provided at the outer end of the axle. The docking end can be a square head or a triangular head, or a non-circular head. The height of the axle of each set of steel cable drive modules is different and staggered. The device is also provided with an operating crank, which is detachably connected to the docking end of the rotating shaft. The operating crank is provided with a corresponding square hole or triangular hole, and the two can be matched to achieve shaking. The drive device also includes a drive motor located in the crossbeam box or the support box, and the drive motor is connected to one of the steering wheels for transmission.

[0033] The cable-turning wheel at the lower end of the vertical section is a double-grooved wheel, one of which is used to hang the cable, and the other is directly connected to the drive motor through the drive cable. When the drive motor rotates, it drives the double-grooved wheel to rotate, and then drives the cable above and the slide to move.

[0034] The other steering wheels of each set of steel cable drive modules are all mounted on the supporting box through a rotating shaft, and the steering wheels at corresponding positions of each set can share one rotating shaft.

[0035] Each track set consists of two symmetrically mounted L-shaped tracks, each comprised of vertical side panels and a horizontal base. The width of the slide matches the distance between the inner sides of each track set's two vertical side panels, preventing the slide from moving between the rails and detaching from them. The movement of the steel cables drives the slides along the upper surfaces of the track bases, thereby driving the movement of the suspended traffic signs. The lower layer of the horizontal cable section is located on the upper surface of the slide and is fixedly connected to it via a pressure plate. The lower layer of the horizontal cable section is located in the center of the track set, parallel to the tracks.

[0036] The suspension rod is a retractable structure, which is used to adjust the height of the sign during installation. The lower end of the suspension rod and the sign are detachably connected, and the sign can be replaced with different shapes and patterns as needed.

[0037] The inner side of the supporting box is provided with a recessed hidden groove, the lateral width of which is not less than the lateral width of the traffic sign. When there is no problem with the road surface, all the signboards are retracted into the hidden groove.

[0038] An operation panel is installed on the side of the support box. Inside the support box, a control module is connected to the operation panel. The control module is connected to N motor drive modules, a communication module for networking, and a Bluetooth module. A QR code is also installed on the side of the support box. The communication module is used for remote control by traffic management personnel, and the Bluetooth module allows for interactive control with the mobile phones of on-site personnel. After the QR code is scanned by the mobile phone, on-site personnel can control the device via the network. On-site personnel can directly control the device through the operation panel.

[0039] The lower ends of the two supporting boxes are fixedly connected to the ground through fasteners.

[0040] The working process of the device:

[0041] The device is installed astride a highway or road. When an accident occurs on the road or road maintenance is required, multiple lanes will be occupied. At this time, by controlling the multi-lane suspended warning device, its drive motor drives the slide and suspension rod to move, and moves the indicator sign above the designated lane to prompt oncoming vehicles to avoid these lanes. After the road surface returns to normal, the device is controlled to move all the suspension rods into the hidden groove.

[0042] Example 2: See Figure 9 The second embodiment is essentially the same as the first embodiment, and the similarities are not repeated here. The difference is that the lower ends of the two support boxes in the second embodiment are equipped with a plurality of running wheels. When an accident occurs on the road or road maintenance requires multiple lanes, and the device is not available on site, a multi-lane suspended warning device closer to the scene can be remotely controlled through its running wheels to move along the inner edge of the highway and road guardrail toward the scene. Upon arrival, the various signposts are moved to the tops of the corresponding lanes, referring to the process of the first embodiment.

[0043] For the edge of a highway or road, a groove track matching the width of the running wheel can be provided, and the lower half of the running wheel is inserted into the groove track for running, so that the running direction is more stable.

[0044] In Examples 1 and 2, to address the issue of manual sign positioning accuracy, markings corresponding to lane centers are provided on the surface of the crossbar box. Adjusting the sign to the corresponding markings ensures it aligns with the lane centerline. In this example, the markings are digital. To further reduce wind resistance, the non-patterned areas within the sign can be hollow or porous.
