The invention provides a connecting system and a railway tanker. The connecting system comprises a tank body, a bottom frame, connecting devices and a pressing plate; a base is arranged at the bottom of the tank body, a floor is arranged at the top of the bottom frame and located below the base, and supports the base; a first penetrating hole is formed in the floor, and the first penetrating hole extends in the height direction of the tank body; each connecting device comprises a connecting rod and an elastic piece, the connecting rods are slidably arranged in the first penetrating hole and extend in the height direction of the tank body, the top ends of the connecting rods are located above the floor, and the elastic pieces are connected between the connecting rods and the floor; and the pressing plate is arranged at the top ends of the connecting rods, the elastic pieces can apply elastic force on the connecting rods, so that the pressing plate elastically presses the base. The connecting system and the railway tanker can improve the safety.
Description
technical field [0001] The invention relates to railway vehicle equipment technology, in particular to a connection system and a railway tank car. Background technique [0002] The railway aluminum tank car is a railway tank car used to transport strong corrosive substances such as concentrated nitric acid. [0003] Existing railway aluminum tank cars include an underframe and a tank body, and the base of the tank body is bolted to the floor of the underframe. [0004] Since the base of the tank body is made of aluminum alloy and the bottom frame is made of steel, when the temperature changes, there will be a difference in deformation between the base of the tank body and the floor of the bottom frame, which will cause the base of the tank body and the bottom frame The relative longitudinal displacement between the floors has potential safety hazards. Contents of the invention [0005] The invention provides a connection system and a railway tank car to improve safety. ...
