Description

Technical Field

[0001] The utility model relates to the technical field of road reminders, in particular to a sign rack for road transportation of dangerous goods. Background Art

[0002] Dangerous goods refer to items that are prone to combustion, explosion, corrosion, poisoning, or radioactivity, and are likely to cause personal injury, death, and property damage during transportation and storage. Special protective facilities and measures are required for these items. Dangerous goods are generally divided into ten categories: explosives, oxidizers, compressed and liquefied gases, self-igniting items, items that burn when exposed to water, flammable liquids, flammable solids, poisons, corrosive items, and radioactive items. Certain flammable goods, such as cotton, linen, and coal powder, may be treated as ordinary cargo if their content, concentration, and piece weight are all below the prescribed limits. The use of sign racks is very important in the transportation of dangerous goods. They are mainly used to display the identification and warning information of dangerous goods.

[0003] In road warning technology, existing dangerous goods sign stands are easily blown down by the wind due to their light weight when in use, causing the dangerous goods sign stands to lose their purpose of warning passing vehicles and easily causing accidents. At the same time, existing dangerous goods sign stands cannot adjust their height. When encountering a road section with a steep slope in the distance, it is impossible to ensure that the sign is at the optimal height, and it cannot be observed in time by distant vehicles, posing certain safety hazards.

[0004] To this end, we propose a sign rack for road transport of dangerous goods. Utility Model Content

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a sign frame for road transportation of dangerous goods.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a sign rack for road transportation of dangerous goods, comprising a base plate body and a sign rack body; the top wall of the base plate body is provided with a lifting mechanism for lifting the sign rack body, the lifting mechanism comprising two slide cylinders and two slide rods; the top wall of the sign rack body is provided with a warning mechanism, the warning mechanism comprising a horizontal plate and a warning light; a storage bin is provided on the bottom inner wall of the base plate body, a bearing plate for stably placing the sign rack body is provided inside the storage bin, and universal wheels are fixedly connected to the bottom walls of the four corners of the base plate body.

[0007] As an optimal technical solution of the present invention, the two slides are respectively fixedly mounted on the left and right top wall surfaces of the base plate body, the bottom ends of the two slide rods are respectively slidably arranged in the two slides, the top ends of the two slide rods are respectively fixedly mounted on the bottom wall surface of the sign frame body and the outer side walls of the two slides at one end away from each other are threadedly connected with a tightening handwheel.

[0008] As an optimal technical solution of the present invention, the horizontal plate is fixedly mounted on the top wall of the sign frame body, the front end wall of the horizontal plate is provided with a light trough adapted to the warning light and the warning light is fixedly mounted in the light trough.

[0009] As a preferred technical solution of the present invention, the top wall of the base plate body is threadedly connected with a threaded handle, and the bottom end of the threaded handle passes through the base plate body and is rotatably connected to the top wall of the bearing plate.

[0010] As an optimal technical solution of the present invention, guide rods are respectively provided on the left and right sides of the threaded handle, the bottom ends of the two guide rods respectively pass through the base plate body and are fixedly connected to the top wall of the supporting plate, and the two guide rods are respectively slidably connected to the base plate body.

[0011] As a preferred technical solution of the present invention, a plurality of counterweight bins are provided on the front end wall of the bearing plate and a counterweight block is placed in each counterweight bin.

[0012] The utility model provides a sign rack for road transport of dangerous goods, which has the following beneficial effects:

[0013] 1. This is a sign stand for road transport of dangerous goods. When in use, when a user is driving a dangerous goods truck on the road and encounters a vehicle breakdown, the user places the device in a suitable position and pulls the slide bar upward, so that the slide bar drives the sign stand body to move upward, thereby adjusting the sign stand body to a suitable height. When encountering a road section with a steep slope in the distance, the sign stand body can be observed in time by distant vehicles, thereby improving the visibility of the sign stand body. The setting of the warning light can play an auxiliary reminder role.

[0014] 2. This kind of sign rack for road transport of dangerous goods, when in use, when encountering strong winds, turn the threaded handle, the threaded handle drives the bearing plate to move downward, so that the bearing plate contacts the ground, and then insert the counterweight block into each corresponding counterweight bin. Through the setting of the counterweight bin and the counterweight block, the counterweight effect is achieved, which can effectively prevent the device from being blown down by strong winds and effectively improve the stability of the device bracket.
