[0026] A rocket is a vehicle that is propelled forward by the reaction force generated by the working medium ejected by the rocket engine. Usually, the launch of a rocket requires the assistance of a rocket rack, which can support the rocket and adjust the launch angle. In the meteorological field, some rockets or artillery shells are needed to bring rain or provide other meteorological assistance effects to facilitate agricultural production, etc.

[0027] The rocket rack is heavy and difficult to move. The commonly used method of moving it is to use some lifting tools to transport the rocket rack to the vehicle compartment and then transport it by vehicle. However, the lifting tools have great restrictions on the site and are inconvenient to operate.

[0028] To do this, please refer to Figure 1 The present application provides a loading and unloading device for a mobile rocket rack 1, comprising a mobile rocket rack 1, wherein a plurality of transport wheels 11 and grounding wheels 12 are arranged at the bottom of the mobile rocket rack 1, wherein the transport wheels 11 are located on one side of the grounding wheels 12, and the lowest height of the transport wheels 11 is higher than the lowest height of the grounding wheels 12.

[0040] Please refer to Figure 1 In some examples, the bottom plate 52, the middle vertical plate 53 and the top bearing plate 54 can be made of the same material as the bearing platform 4, and can be made of cast iron, so that they have good strength. The top surface of the top bearing plate 54 can be set to a certain degree of roughness to reduce the friction when the transport wheel 11 slides, thereby protecting the transport wheel 11.

[0041] Please refer to Figure 1 In some examples, the bottom side plate 52, the middle vertical plate 53 and the top bearing plate 54 can form an I-shaped structure, which can have higher strength and avoid deformation during use.

The middle vertical plate 53 is arranged vertically so that the cross section of the slide rail 5 forms an axisymmetric structure along the vertical direction, and a groove space 51 is formed on both sides of the middle vertical plate 53. This method can make the slide rail 5 more beautiful as a whole, and the load-bearing force of the slide rail 5 is more uniform when carrying the mobile rocket rack 1, which is helpful for the stable support of the rocket rack. The groove space 51 can be used to accommodate the grounding wheel 12 to prevent the mobile rocket rack 1 from shaking or detaching due to the conflict between the grounding wheel 12 and other parts when sliding on the slide rail 5.
