The invention belongs to the technical field of transportation, and particularly relates to a cold chain transportation device. The device comprises a box body and a cab, the box body is fixedly connected with the cab, an air cylinder, an air bag and an air pipe are fixedly arranged in the box body, an opening matched with the air pipe is formed in a buffer plate, and the buffer plate and the boxbody are sealed in a sliding mode. When the vehicle is braked, goods collide with the buffer plate, the buffer plate is fixedly connected with the air cylinder, the air cylinder is airtight, and the good goods buffer effect can be achieved. The air cylinder can generate heat in the air compressing process to supply heat to the cab. In the braking process of the vehicle, the piston moves towards the box body to compress air into the air bag through the air pipe, so that cold air is prevented from entering the air cylinder to influence a cab. When the air bag is inflated all the time and the airpressure is large, the one-way valve at the opening can be opened for deflation, and the air bag is prevented from being damaged due to the too large air pressure.
本方案属于运输技术领域,具体涉及一种冷链运输装置,包括箱体和驾驶室,所述箱体和驾驶室固定连接,所述箱体内固定设有气缸、气囊和气管,所述缓冲板上开有与气管相配合的开口,所述缓冲板与箱体滑动密封。车辆刹车时,货物撞上缓冲板,缓冲板和气缸固定连接,气缸是密闭的,能够起到很好的给货物缓冲的作用。气缸在压缩空气的过程中能够产生热量,给驾驶室供暖。在车辆刹车过程中,活塞向箱体方向移动,把气体通过气管压缩到气囊中,以免使冷气进入气缸从而影响到驾驶室。气囊开口处的单向阀只出气不进气,当气囊一直被充气,气压比较大需要放气时,可打开开口处的单向阀放气,防止气囊由于气压过大损坏。
