Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to an auxiliary movable guardrail for lane change. Background Art

[0002] As we all know, lanes refer to specific areas on the road for vehicles to travel, usually divided by markings, signs or other traffic control facilities. The main function of lanes is to regulate traffic flow and ensure that vehicles travel according to certain rules and directions, thereby improving road use efficiency and traffic safety. Guardrails are a type of traffic safety facility, usually set up next to or in the middle of a lane to prevent vehicles from deviating from the lane due to loss of control or erroneous driving.

[0003] In some cases, traffic flow may change, such as traffic accidents, road construction, special events or rush hours. At this time, lanes need to be quickly adjusted to adapt to changing traffic needs. However, traditional lane change auxiliary mobile guardrails usually require manual movement of guardrails that are both rigid and flexible. Manual movement of guardrails poses a high safety risk, and workers may be exposed to the risk of fast-moving vehicles. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose an auxiliary mobile guardrail for lane change. When the auxiliary mobile guardrail for lane change is used, the servo motors on both sides are started to drive the threaded rod to rotate and drive the limit blocks to move at the same time. The limit blocks slide in the sliding grooves, and then the limit blocks on both sides are limited to make them move laterally, thereby driving the guardrail to move laterally at the dotted line position. Automatically driving the guardrail to move can reduce or eliminate manual operation and improve the safety of operation. During the movement, the alarm is started to remind surrounding vehicles at all times. A plurality of yellow warning rollers are used to assist in reminding vehicles at all times of the position of the guardrail.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An auxiliary movable guardrail for lane change, comprising a road, a plurality of installation cavities are opened inside the road, the front ends of the inner walls of the installation cavities are fixedly connected to servo motors, the output ends of the servo motors are fixedly connected to threaded rods, the rear ends of the threaded rods are rotatably connected to the rear ends of the inner walls of the installation cavities, and the middle parts of the top surfaces of the installation cavities are connected through sliding grooves;

[0007] A plurality of guardrails are arranged in the middle of the upper surface of the road, and limit blocks are fixedly connected on both sides of the lower surface, mounting frames are fixedly connected on both sides of the outer walls of the front and rear ends of the guardrails, and the outer walls of the adjacent ends of the mounting frames are bolted with guardrails, and alarm lights are arranged at the four corners of the upper surface of the guardrails, a GPS receiver is fixedly connected to the outer wall on the side of the limit blocks away from the center of the road, and an infrared sensor is arranged on the lower part of the outer wall on the end of the mounting frame away from the center of the road.

[0008] Through the above technical scheme, compared with the existing auxiliary mobile guardrail for lane change, when the auxiliary mobile guardrail for lane change is used, through the GPS receiver, the receiver can receive satellite signals and determine the position of the guardrail, and then can track the position of the guardrail in real time and communicate with the central control system. When working with the infrared sensor, it will emit infrared beams. These beams form an invisible infrared line in front of the sensor. When the vehicle passes, they will block the beam, causing the light to be blocked, and then cause the sensor to detect the interruption or change of the light. Whenever the sensor detects that the light is blocked, the system will record the vehicle once. In this way, the system can record the number of times the vehicle passes in real time, and calculate the size of the traffic flow accordingly, upload the data to the system, and the artificial intelligence analysis determines whether the conditions for the sliding of the guardrail are met. Finally, the transportation bureau makes the final decision whether to control the sliding guardrail to adjust the lane, thereby starting the servo motor to drive the guardrail to move, thereby alleviating the congestion of vehicles on the highway caused by a series of situations such as traffic accidents, and has high practical performance.

[0009] Furthermore, the lower ends of the limit blocks all pass through the sliding grooves to the interior of the installation cavity and are threadedly connected to the threaded rod;

[0010] Through the above technical solution, the lower end of the limit block passes through the sliding groove to the inside of the installation cavity and is threadedly connected to the threaded rod, so that the movement of the threaded rod drives the limit block to move.

[0011] Furthermore, the limit blocks are slidably connected inside the installation cavity and the sliding groove respectively;

[0012] Through the above technical solution, the limiting block is slidably connected inside the installation cavity and the sliding groove respectively, so it is convenient to limit the limiting block so that it can move horizontally.

[0013] Furthermore, the outer wall of the adjacent side of the mounting frame is threadedly connected with a plurality of protective rods, and one side of the outer wall of the adjacent side of the protective rod is bolted with a plurality of yellow warning rollers;

[0014] Through the above technical solution, the visibility of the guardrail can be enhanced by the yellow warning roller, so that drivers and pedestrians can notice it from a distance.

[0015] Furthermore, the upper parts of the inner walls on both sides of the installation cavity are fixedly connected with reinforcing ribs, and the upper ends of the reinforcing ribs are fixedly connected to the top surface of the installation cavity;

[0016] Through the above technical solution, the strength inside the installation cavity can be easily enhanced by the reinforcing ribs.

[0017] Furthermore, the upper surface of the road is coated with a plurality of dotted lines;

[0018] Through the above technical solution, the dotted lines are used to facilitate improved coordination.

[0019] Furthermore, universal wheels are fixedly connected to the four corners of the lower surface of the guardrail;

[0020] Through the above technical solution, the universal wheels facilitate movement with the guardrail.

[0021] Furthermore, the inner walls on both sides of the sliding groove are fixedly connected with folding fence plates, and the outer walls on the adjacent sides of the folding fence plates are fixedly connected with the outer walls of the limit blocks;

[0022] Through the above technical solution, the foldable fence plate can be compressed or stretched following the movement of the limit block, thereby preventing external dust from entering and causing damage to components.

[0023] The utility model has the following beneficial effects:

[0024] 1. The utility model proposes an auxiliary movable guardrail for lane change. Compared with the existing auxiliary movable guardrail for lane change, when the auxiliary movable guardrail for lane change is used, the servo motors on both sides are started to drive the threaded rod to rotate and drive the limit block to move at the same time. The limit block slides in the sliding groove, and then the limit blocks on both sides are limited to make them move laterally, thereby driving the guardrail to move laterally at the dotted line position. Automatically driving the guardrail to move can reduce or eliminate manual operation and improve the safety of operation. During the movement, the alarm is started to remind surrounding vehicles at all times. A plurality of yellow warning rollers are used to assist in reminding vehicles at all times of the position of the guardrail.
