Description

Technical Field

[0001] The utility model relates to the technical field of highway maintenance safety supervision, in particular to an unmanned vehicle for highway maintenance safety supervision. Background Art

[0002] At present, the safety supervision of construction sites on the front line of highway maintenance mainly relies on on-site supervision by maintenance, road management centers and other units during inspections, and dynamic full-process tracking cannot be achieved.

[0003] There are also methods of remotely monitoring construction sites by calling road monitoring probes, installing small surveillance cameras on construction sites, and adding on-board monitoring to construction vehicles. These methods have the following problems: 1. The field of view of road cameras and on-board monitoring is limited, the clarity is low, and they cannot effectively cover maintenance sites with a large area; 2. Small surveillance cameras cannot move independently and need to be frequently moved by construction workers, making on-site supervision relatively passive.

[0004] There are also improvements to existing technologies. A Chinese invention patent with authorization publication number CN112780895B discloses an unmanned patrol security monitoring vehicle for construction sites. This invention's structural design not only solves the aforementioned problems but also effectively protects the camera. To damage the camera, the transparent cover must be pre-destroyed. Once damaged, it triggers a series of control transmissions on the vehicle, forcing the protective cover to fall over the camera, protecting it and making the unmanned monitoring vehicle safer. However, when applying the disclosures in this patent document to frontline highway maintenance construction sites, the following problems arise: There is no warning function, posing a significant safety hazard to fast-moving vehicles on the highway.

[0035] The utility model provides an unmanned vehicle for highway maintenance and safety supervision, comprising a movable platform 1, a camera 11 being installed at the upper end of the movable platform 1, and a warning unit 2, the warning unit 2 comprising: a road cone fixing member 22, the road cone fixing member 22 comprising a conical cylinder 221, the conical cylinder 221 having openings at opposite ends along its central axis, the central axis of the conical cylinder 221 being arranged in a vertical direction, the large-diameter end of the conical cylinder 221 being located below its small-diameter end, the large-diameter end of the conical cylinder 221 being provided with a base 222, the end of the base 222 away from the conical cylinder 221 being provided with a plurality of rollers 223 in contact with the road surface; a connecting member 21, the base 222 being detachably connected to the movable platform 1 via the connecting member 21.

[0036] The present invention uses the camera 11 on the movable platform 1 to carry out mobile monitoring of the maintenance construction site. When the present invention is needed to serve as a warning, the road cone fixing member 22 is connected to the movable platform 1 through the connecting member 21, and the road cone is placed on the conical cylinder 221. After the present invention moves to the upstream of the maintenance area, it can protect the construction workers and patrol personnel in the maintenance area. When it is necessary to place a road cone in an emergency, the road cone can be placed through the movable platform 1 without manual placement, which has a higher safety factor.

[0037] As we all know, road cones (also known as traffic cones, warning cones, or cone-shaped markers) are common traffic safety devices used to direct traffic flow, indicate road construction areas or dangerous areas, and temporarily redirect traffic flow. Road cones can be divided into two types based on whether they have an opening on the top: open-top cones and closed-top cones.

[0038] When the top of the traffic cone has an opening, to ensure a secure connection between the traffic cone and the cone 221, a preferred embodiment of the present invention further improves the traffic cone fixing member 22 by including an elastic cord 224, one end of which is connected to the base 222, the connection between which is located inside the cone 221; and a limiting rod 225, the other end of which is connected to the limiting rod 225, the length of which is greater than the length of the opening at the small-diameter end of the cone 221. After the traffic cone is mounted on the cone 221, the limiting rod 225 is pulled out from the inside of the cone 221 and positioned horizontally. Under the tension of the elastic cord 224, the opposite ends of the limiting rod 225 contact the opposite ends of the cone in the radial direction, ensuring a secure connection between the traffic cone and the cone 221.

[0039] Regarding how to place the limit rod 225, as a preferred embodiment, the further improvement of the present invention is that the road cone fixing member 22 also includes a limit rod fixing member 226, and the limit rod fixing member 226 includes: a connecting rod 2261, the connecting rod 2261 is arranged on the inner side of the conical cylinder 221, and one end of the connecting rod 2261 is fixedly connected to the inner side surface of the conical cylinder 221; an insert tube 2262, the insert tube 2262 is arranged on the inner side of the conical cylinder 221, and the insert tube 2262 is fixedly connected to the inner side surface of the conical cylinder 221 through the connecting rod 2261, and the upper end surface of the insert tube 2262 is provided with a socket, and the socket is arranged in the vertical direction. The limit rod 225 is plugged into the socket. When the limit rod 225 is plugged into the socket, one end of the limit rod 225 extends from the inner side of the conical cylinder 221. Specifically, an annular limiting block 22511 protrudes from the outer peripheral surface of the limiting rod 225 , and the limiting block 22511 is limitedly matched with the upper end surface of the insert 2262 .

[0040] Before the traffic cone is put on the conical tube 221, the limiting rod 225 is inserted into the insertion hole and is limited by the limiting block 22511. At this time, the limiting rod 225 is arranged in the vertical direction. The limiting rod 225 arranged along the vertical square will not interfere with the traffic cone being put on the conical tube 221. After the traffic cone is put on the conical tube 221, one end of the limiting rod 225 extends from the inner side of the conical tube 221, which facilitates the removal of the limiting rod 225 from the inner side of the conical tube 221 when the traffic cone is limited by the limiting rod 225.

[0041] When the top of the road cone is not open, in order to ensure the firmness of the connection between the road cone and the cone tube 221, as a preferred embodiment, the further improvement of the present invention is that the road cone fixing member 22 also includes a limiting cone tube 227, which is outermostly arranged on the bottom of the cone tube 221, and a preset gap is provided between the side wall of the limiting cone tube 227 and the side wall of the cone tube 221, and the central axis of the limiting cone tube 227 and the cone tube 221 coincide with each other. A limiting ring 2271 is provided at the bottom of the outer side surface of the limiting cone tube 227, and the limiting ring 2271 is detachably connected to the base 222; the limiting rod 225 is a telescopic rod. Specifically, the limiting rod 225 includes a first part 2251 and a second part 2252. A limiting hole is provided on one end face of the first part 2251. The second part 2252 is plugged into the limiting hole. A spring 2253 is provided in the limiting hole. One end of the spring 2253 is fixedly connected to the bottom of the limiting hole, and the other end of the spring 2253 is fixedly connected to the second part 2252.

[0042] When the road cone is placed on the conical cylinder 221, the second portion 2252 of the limiting rod 225 is compressed downward under the action of the road cone's gravity. After the road cone falls into place, the limiting cone cylinder 227 is placed on the road cone, and the limiting ring 2271 and the base 222 are locked by the bolt 228. The support ring at the bottom of the road cone is clamped by the limiting ring 2271 and the base 222, and the road cone is stably placed on the conical cylinder 221.

[0043] Therefore, the utility model is not only applicable to traffic cones with an opening at the top, but also applicable to traffic cones with no opening at the top, and has strong versatility.

[0044] Furthermore, the camera 11 includes a first camera 111 and a second camera 11211. The first camera 111 is located at the front end of the movable platform 1. The first camera 111 is powered by the movable platform 1, while the second camera 11211 is powered by a separate backup power supply. Specifically, the first camera 111 is a traveling probe, while the second camera 11211 is a 4G network model and serves as the primary monitoring probe. The use of a 4G network model for the second camera 11211 effectively ensures network stability.

[0045] Furthermore, the connecting member 21 is a multifunctional traction rope, one end of which is connected to the base 222, and the other end of which is connected to the movable platform 1. When the utility model is required to have a warning function, the multifunctional traction rope is used to connect the traffic cone fixing member 22 and the movable platform 1. When the utility model is moved in a relatively narrow area and the warning function is not required, the multifunctional traction rope and the traffic cone fixing member 22 are separated and the multifunctional traction rope is wrapped around the movable platform 1.

[0046] Furthermore, the movable platform 1 is a tracked steel remote control (RC) vehicle. A tracked steel RC vehicle is a remote-controlled model vehicle primarily made of metal and driven by tracks. This type of RC vehicle is often used in complex terrain, such as mud, snow, sand, or rocky areas, because the tracks provide better grip and maneuverability.

[0047] Furthermore, the movable platform is equipped with an RGB flashing light set (not shown). The RGB flashing light set is a lighting device that can produce multiple colors and flash rapidly. The setting of the RGB flashing light set enhances the warning function of the utility model.

[0048] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
