[0002] Road signs are an important part of traffic safety infrastructure. They play a key role in road traffic management, helping drivers and pedestrians to drive and pass safely by providing various traffic information and instructions. The existence of road signs can enhance traffic participants' cognition and understanding of the road environment, guide them to abide by traffic rules, reduce the incidence of traffic accidents, and improve road safety. Therefore, road signs are regarded as one of the important parts of traffic safety infrastructure.
[0003] Traffic information on road signs plays an important role in guiding drivers and pedestrians, such as indicating routes, warning of dangers, and indicating speed limits. However, long-term exposure to the natural environment and external factors, such as sun, rain, wind, snow, etc., may cause the text on road signs to be blurred, the color to fade, and the signs to be deformed, affecting the accurate communication of information. Therefore, regular inspection and maintenance of road signs can ensure the clarity of information, avoid misleading and confusion, and ensure the safety of traffic participants.
[0004] The existing inspection and maintenance technology lacks a structure for adjusting the height of road signs, and the height of road signs cannot be adjusted reasonably. In addition, the road signs have a large force-bearing area, so they are easily damaged once encountering strong winds.
[0005] Therefore, in view of the above problems, a traffic safety infrastructure inspection and maintenance device is proposed. Utility Model Content
[0006] In order to make up for the shortcomings of the existing technology, the problem of lack of structure for adjusting the height of road signs, inability to reasonably adjust the height of road signs, and the large force-bearing area of road signs themselves, so they are easily damaged once encountering strong winds.
[0007] The technical solution adopted by the utility model to solve its technical problems is: a traffic safety infrastructure inspection and maintenance device described in the utility model comprises a support module, a rebound module, a loading and unloading module and an indicating module, the support module comprises a threaded tube, a forward thread and a reverse thread are provided on the threaded tube, one side of the forward thread is rotatably connected with a forward moving block, one side of the reverse thread is rotatably connected with a reverse moving block, the forward moving block and the reverse moving block are both fixedly installed with a first bearing, the middle of the first bearing is rotatably connected with a connecting arm, and the ends of the two connecting arms are rotatably connected with a second bearing, both ends of the threaded tube are penetrated with support blocks, the left end of the threaded tube is fixedly installed with a knob, the bottom of the support block is fixedly installed with a bottom plate, the upper part of the second bearing is fixedly connected with a support seat, the support seat is fixedly connected with a support rod, the support rod is sleeved with a spring, the support rod is fixedly sleeved with a rotating shaft, the rotating shaft is fixedly sleeved with a mounting sleeve, and the two ends of the spring are fixedly connected with the mounting sleeve.
[0008] Preferably, a mounting plate is fixedly mounted on the side of the mounting sleeve, and screw holes are formed on the mounting plate.
[0009] Preferably, the number of the screw holes is two, fixing screws are passed through the two screw holes, and the ends of the fixing screws are threadedly connected with hexagonal nuts.
[0010] Preferably, a road sign is slidably connected between the two mounting card plates, and a mounting hole is provided on the road sign.
[0011] Preferably, the diameter of the mounting hole is the same as that of the screw hole.
[0012] Preferably, a signboard is fixedly connected to the side of the road sign.
[0013] The utility model is beneficial in that:
[0014] 1. By turning the knob, the threaded tube is driven to rotate. When the threaded tube rotates, the forward thread will rotate, and the reverse thread will also rotate, so that the forward moving block on the forward thread and the reverse moving block on the reverse thread will move in opposite directions, thereby driving the movement of the two first bearings, and further driving the movement of the two connecting arms, so as to adjust the angle between the two connecting arms, and thus adjust the height of the support seat, and thus adjust the height of the support rod, so as to adjust the height of the entire device, thereby solving the problem of requiring different heights to obtain better indication effects.
[0015] 2. When the wind blows, due to the large area of the road sign, the wind will exert force on the road sign. The road sign is fixed between two mounting plates, which also exerts force on the mounting plates, and then exerts force on the mounting sleeve. The mounting sleeve will rotate on the two shafts, driving the spring torque until it rotates to the same angle as the wind direction. After the wind stops, the spring will rebound and rebound the road sign to its original position, which is conducive to strengthening the protection of the road sign.
