[0022] The loader 3 is then moved to the position where the liquefied natural gas tanks are to be loaded. Then, the staff starts the loading mechanism, which drives the loading mechanism to move the loading rack 3 along the mounting rack 2 to a suitable height, that is, a height at which it is convenient for the staff standing on the vehicle to operate the liquefied natural gas tanks in the loading rack 3. Then, the staff on the vehicle takes down the multiple liquefied natural gas tanks in the loading rack 3 and places them on the vehicle, thereby completing the loading operation of the liquefied natural gas tanks. After the loading is completed, there is no need to manually lift the liquefied natural gas tanks for loading, and multiple liquefied natural gas tanks can be loaded at one time, effectively improving the loading efficiency of the liquefied natural gas tanks. The loading mechanism is started to lower the loading rack 3 and reset it, and the loading operation of the liquefied natural gas tanks can be repeated. Through the entire device, multiple liquefied natural gas tanks can be loaded at one time, with high loading efficiency and reducing the labor burden of the staff.

[0023] In a further preferred embodiment of the present utility model, the loading mechanism includes: a motor 4 fixedly mounted on the mounting frame 2; a mounting slot 5 provided on the mounting frame 2, a mounting shaft 6 rotatably mounted in the mounting slot 5, one end of the mounting shaft 6 being fixedly connected to the output shaft of the motor 4; two winches 7 fixedly sleeved on the mounting shaft 6, a pull rope 8 being wound around both winches 7; two connecting rings 9 respectively fixedly mounted on the outer walls on both sides of the placement frame 3, the two connecting rings 9 being fixedly connected to one end of the two pull ropes 8 respectively.
