A first door 12 is hinged to one end of the transport vehicle body 1, and a second door 13 is hinged to one side of the transport vehicle body 1. The top covers 2 are closed by closing one first and then the other.

[0024] Please refer to it again. Figure 1 and Figure 5 The transport vehicle body 1 is equipped with a top-opening mechanism that flips open the top cover 2. The top-opening mechanism includes a hydraulic rod 4. The fixed end of the hydraulic rod 4 is hinged to the inner wall of the transport vehicle body 1 by a pin, and the telescopic end of the hydraulic rod 4 is hinged to the top cover 2 by a pin. By activating the hydraulic rod 4, the telescopic end of the hydraulic rod 4 retracts or extends, thereby pushing the top cover 2 to flip open or close. A protective cover 41 is fixedly connected inside the transport vehicle body 1. The oil pipe of the hydraulic rod 4 is placed inside the protective cover 41. The hydraulic station that controls the operation of the hydraulic rod 4 is installed at the bottom of the frame. The protective cover 41 is used to store and protect the oil pipe connecting the hydraulic rod 4 and the hydraulic station.

[0025] Please refer to it again. Figure 1 and Figure 5 Each of the two top covers 2 is fixedly connected to a first sealing strip 22 at one end close to each other, and a second sealing strip 23 is fixedly connected to one side of the top cover 2. The first sealing strip 22 is used to seal the gap when the two top covers 2 are closed, and the second sealing strip 23 is used to seal the gap between the top cover 2 and the transport vehicle box 1 when they are closed.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The transport vehicle 1 is equipped with a fixing mechanism for fixing the shell rack at the front and rear. The shell rack is a rectangular cage structure formed by welding steel pipes, which is existing technology and will not be described in detail in this application. The fixing mechanism includes two fixing slides 5 fixed to the bottom wall of the transport vehicle 1. Right-angle teeth 51 are fixedly connected inside the fixing slides 5. Two sliding baffles 6 are slidably connected on the two fixing slides 5. Connecting sliders 61 are fixedly connected to the bottom of both ends of the sliding baffles 6. The connecting sliders 61 are slidably connected to the outer side of the fixing slides 5. By pushing the two sliding baffles 6 to slide the shell rack placed between the two fixing slides 5 and the two sliding baffles 6, the two sliding baffles 6 clamp and fix the shell rack.

[0027] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4Both ends of the sliding baffle 6 are slidably connected to sliding stop rods 7. The inclined surface at the bottom of the sliding stop rod 7 is parallel to the inclined surface of the right-angle tooth 51. Both ends of the sliding baffle 6 are provided with connecting cavities. A connecting plate 71 is fixedly connected to the sliding stop rod 7. The connecting plate 71 slides inside the connecting cavity. A spring 72 is fixedly connected to the top of the connecting plate 71. When the sliding baffle 6 slides toward the shell rack, the inclined surface of the right-angle tooth 51 presses against the inclined surface at the bottom of the sliding stop rod 7, thereby pushing the sliding stop rod 7 to rise. Then, the spring 72 rebounds and drives the sliding stop rod 7 to quickly descend and slide back to its original position. The plane on the side of the sliding stop rod 7 and the plane of the right-angle tooth 51 form a blocking effect to limit the sliding baffle 6 from sliding away from the shell rack, thereby clamping the shell rack between the two sliding baffles 6.

[0028] Working principle: The transport box 1 is installed on the transport vehicle frame. The top cover 2 is flipped open by activating the hydraulic rod 4. The shell rack is hoisted into the transport box 1 using hoisting equipment, placing the shell rack between two fixed slide rails 5 and two sliding baffles 6. The sliding baffles 6 are then pushed to slide towards the shell rack. The inclined surface of the right-angle teeth 51 presses against the inclined surface at the bottom of the sliding baffle 7, pushing the sliding baffle 7 upward. Then, the spring 72 returns and drives the sliding baffle 7 to quickly slide and return to its original position. The plane on the side of the sliding baffle 7 and the plane of the right-angle teeth 51 form a blocking effect, restricting the sliding baffle 6 from sliding away from the shell rack, thus clamping the shell rack between the two sliding baffles 6. After fixing, the two top covers 2 are flipped and closed by activating the hydraulic rod 4. The two first sealing strips 22 are used to seal the joint between the two top covers 2, and the sealing area is covered by the shielding strip 8.
