Description

Technical Field

[0001] The utility model belongs to the technical field of dangerous goods transportation, and particularly relates to a protective device for dangerous goods transportation. Background Art

[0002] There are many types of dangerous goods, and dangerous chemicals are one of them. Dangerous chemicals refer to highly toxic chemicals and other chemicals that are harmful to human body, facilities and environment, which have properties such as poisoning, corrosiveness, explosion, combustion and combustion-supporting. Since dangerous chemicals have oxidizing, reducing and bleaching properties, etc., chemical industry is needed in industrial production. Therefore, chemical production plants need to transport them to processing plants through transportation equipment to complete the processing tasks of the processing plants.

[0003] A Chinese patent with the announcement number "CN220483998U" discloses a chemical hazardous goods transportation protection device, which relates to the field of devices. The chemical hazardous goods transportation protection device comprises a first load plate and a second load plate, both sides of which are fixedly mounted with side plates, and the outer sides of the two sets of side plates are provided with a protection mechanism for protecting the hazardous goods transportation box, and the protection mechanism comprises a first buffer plate arranged at the outermost side; and two sets of dampers are arranged between the first buffer plate and the side plates.

[0004] However, this device still has some shortcomings. Although it is feasible to complete the anti-vibration buffering function only by means of dampers and springs, the safety protection performance is low. When the entire device is shaken, the dangerous goods placed inside it will still shake back and forth, thereby reducing the protection for the transportation of dangerous goods. Placing the dangerous goods at the bottom inner side of the device also makes it inconvenient for users to take them out later. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a protective device for transporting dangerous goods to solve the problems mentioned in the background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

The dangerous goods are placed on the support plate, and the clamp is slid by the sliding principle. The dangerous goods can be clamped and fixed by the clamp. Finally, the user tightens the bolt and pushes the bolt against the first rubber pad to fix the position of the clamp. The sponge pad can protect both sides of the dangerous goods while preventing the dangerous goods from colliding with the clamp. At the same time, it is convenient to adjust the position of the clamp, which is also convenient for users to clamp and fix dangerous goods of different sizes. Limiting the position of the dangerous goods can effectively prevent the dangerous goods from shaking, thereby effectively improving the protection of the transportation of dangerous goods. When the dangerous goods need to be taken out, the user can start the telescopic cylinder, which can push the support plate upward, so that the dangerous goods can be pushed to the top of the protective box, thereby achieving the purpose of facilitating the removal of dangerous goods.
