Technical Field

The utility model relates to the technical field of traffic safety warning signs, in particular to a retractable triangular warning board.

Background

In the highway engineering industry standard "highway maintenance safety operation code (JTG H30-2015)" issued by the transportation department, various maintenance operations with fixed-point operation time of more than 30 minutes and less than or equal to 4 hours are specified as temporary maintenance operations, and dynamic maintenance operations with continuous movement or residence time of not more than 30 minutes are specified as movable maintenance operations. Wherein the movable maintenance operation is divided into mechanical movable maintenance operation and manual movable maintenance operation. In the regulations, when the manual mobile maintenance operation is performed on the expressway or the primary road while occupying the road surface, it is preferable to seal a certain range of maintenance operation area and execute the maintenance operation according to the regulations related to the temporary maintenance operation. For manual movable maintenance operations such as road shoulder cleaning, a movable sign or a traffic cone is preferably arranged, and the distance from the start point of the manual movable maintenance operation is not preferably less than 150 meters. The manual mobile maintenance operation should avoid peak hours.

The mobile sign includes a manner of suspending the construction sign from the rear of the working vehicle and the machine, and a mobile sign trolley with a power unit or a movable unit (trailer). At present, in the manual moving maintenance operation of a road shoulder, an engineering vehicle with a construction sign hung at the tail is generally arranged as a movable sign of an operation area, and when the movable sign is in place, another manned vehicle sequentially drops maintenance personnel to each working position in the operation area in front of the movable sign, and then the manned vehicle is parked at the front end of the operation area to wait. When the working area is longer (for example, greater than 300 meters), a small number of traffic cones are usually arranged in the working area for personnel safety to perform identification, after maintenance work is completed, maintenance personnel also need to walk to the traffic cone arrangement position to pick up the traffic cones, and then walk or ride on engineering vehicles with construction marks suspended to the front manned vehicle. In the existing maintenance operation, a part of time is wasted on the temporary marks such as traffic cones picked up by the maintenance personnel by walking, and if the portable and easily-recovered temporary marks are provided, the time required by the maintenance operation can be saved, and the working efficiency of the maintenance operation can be improved.

The triangle warning board is used as a conventional traffic sign, can play the same marking effect with a traffic cone, is small in size, has the technical scheme of more increasing the mobility of the triangle warning board in the prior art, for example, in Chinese patent CN106740451A, a remote control self-propelled buzzing flashing triangle warning board is provided, a folding triangle board is arranged on the side face of a traveling vehicle, a motor wheel is arranged at the front end below the traveling vehicle, two traveling wheels are arranged at the rear end of the traveling vehicle, a driving motor, a power supply and a remote control receiver are arranged on the traveling vehicle, a buzzer is arranged at the vertex angle of the folding triangle board, flashing lamps are arranged on three edges, two waist edges are elastic folding hinges, and the triangle flashing light can automatically walk and continuously send buzzing sounds under the remote control of operators.

In chinese patent CN108407712a, a triangle warning sign of automatic walking is provided, including triangle warning sign body, base, power, motor, drive mechanism, bracing piece, walking wheel and follow driving wheel, triangle warning sign body installs in the base top, the base below is equipped with the recess, power, motor are installed in the recess, the base below is equipped with the telescopic link subassembly, the end at the telescopic link subassembly is installed to the walking wheel, the one end of bracing piece is rotated with the top at the back of triangle warning sign body and is connected, and the other end is equipped with the connecting axle, from driving wheel and connecting axle rotation connection, the power is the motor power supply, the motor is connected with the walking wheel through drive mechanism and is used for driving the walking wheel to rotate. The triangular warning sign has a stable structure, can automatically walk and lift, and can also be remotely controlled.

In chinese patent CN115027357a, a self-propelled triangular warning board for expressway is provided, comprising: the mounting rack is fixedly arranged at the bottom of the automobile; the baffle is arranged at the front side of the bottom of the mounting frame; the mounting plates are two in number and are respectively arranged at the left side and the right side of the rear end of the bottom of the mounting frame; the PLC is fixedly arranged on the inner walls of the two mounting plates; and the release mechanism is fixedly arranged on the outer walls of the two mounting plates and is electrically connected with the PLC.
