Technical Field

[0001] This utility model relates to the field of artillery shell transport vehicle top cover technology, specifically a top cover sealing mechanism for an artillery shell transport vehicle. Background Technology

[0002] Artillery shells are munitions with a caliber of 20mm or more that are fired from artillery to achieve killing, blasting, penetration, or other tactical purposes. Transport vehicles are vehicles that can carry goods and are used to quickly deliver objects to designated locations. Transport vehicles are usually used to transport large artillery shells.

[0003] Chinese Patent Publication No. CN214689796U discloses a top-panel swing-open carriage, including a box body with an upper opening. Two symmetrical swing doors are installed at the upper opening of the box body. A hydraulic cylinder is installed within the box body to drive the swing doors laterally and to close or open the upper opening of the box body. This utility model has a reasonable design, simple structure, and convenient use. The carriage with an openable top and two relatively arranged, movable swing doors are driven by hydraulic cylinders installed on the front and rear pillars, making control convenient and movement smooth, facilitating the loading and unloading of large items by workers.

[0004] However, the inventor of the above device believes that there are certain defects. The top cover of the device requires a large amount of space on the left and right sides to move along its trajectory. Moreover, the sealing strip on the side of the top cover is prone to aging and local cracking due to sun and rain exposure over time. This directly affects the sealing performance of the entire vehicle. Therefore, this utility model provides a top cover sealing mechanism for an artillery shell transport vehicle. Utility Model Content

The protective cover 91 protects and stores the oil pipe of the hydraulic rod 9. The hydraulic station that controls the operation of the hydraulic rod 9 is installed at the bottom of the frame supporting the transport vehicle body 1.

[0025] Please refer to Figures 1 and 3 again. One end of the transport vehicle box 1 is fixedly connected to a refrigeration component 11, and the other end of the transport vehicle box 1 is hinged to a first door 12. A guide channel 21 is provided on the top surface of the top cover 2. The refrigeration component 11 is used to refrigerate the inside of the transport vehicle box 1, and the guide channel 21 is used to guide the rainwater falling on the top of the top cover 2. One end of the guide channel 21 is open, so that the rainwater can be discharged from the top of the top cover 2.

[0026] Please refer again to Figures 1, 2, 3, and 4. The top cover 2 is equipped with a sealing mechanism to seal the gap between the two top covers 2. The sealing mechanism includes a sealing strip 4, and both ends of one top cover 2...

[0027] A connecting piece 3 is fixedly connected, and a sealing strip 4 is rotatably connected between the two connecting pieces 3. The longitudinal section of the sealing strip 4 is pentagonal. Both ends of the sealing strip 4 are fixedly connected to connecting blocks 41. Both ends of the other top cover 2 are rotatably connected to a swing pressure rod 5 and a fixed box 6 is fixedly connected. One end of the swing pressure rod 5 presses against the outer surface of the connecting block 41. When the two top covers 2 are closed together, the swing pressure rod 5 is flipped so that the hook end of the swing pressure rod 5 presses against the outer surface of the connecting block 41, which has a pressing effect on the sealing strip 4. The sealing strip 4 is used to guide the rainwater falling on the top of the top cover 2 to the guide groove 21 on the top cover 2.

[0028] Please refer to Figures 1, 3, and 4 again. A first sealing strip 22 is fixedly connected to the ends of the two top covers 2 that are close to each other. The first sealing strip 22 improves the sealing between the two top covers 2. A third sealing strip 42 is embedded at the bottom of the sealing baffle 4.

One end of the swinging rod 5 is fixedly connected to a tension spring 8, and the other end of the tension spring 8 is fixedly connected to the fixed box 6. When the electromagnet 7 is de-energized, its magnetic force, under the action of the tension spring 8, pulls one end of the swinging rod 5 to flip, so that the hook end of the swinging rod 5 moves away from the connecting block 41, releasing the pressing effect on the connecting block 41, so that the two top covers 2 can be flipped open.

[0030] Working principle: The transport vehicle body 1 is installed on the frame. A sealing strip 4 is used to block the gap at the closure of the two top covers 2. The sealing strip 4 guides rainwater falling on the top of the top cover 2 to the inside of the guide channel 21, and finally discharges through the opening of the guide channel 21. When the top cover 2 needs to be flipped open, the electromagnet 7 is de-energized, and its magnetic force, under the rebound of the tension spring 8, pulls one end of the swing rod 5 to flip, causing the hook end of the swing rod 5 to move away from the connecting block 41, releasing the pressing effect on the connecting block 41. The hydraulic rod 9 is then activated to push the top cover 2 to flip open the top of the transport vehicle body 1, facilitating the loading and unloading of large goods. After the two top covers 2 are closed, the electromagnet 7 is re-energized, causing it to generate magnetic force to attract the iron sheet on the swing rod 5. The hook end of the swing rod 5 presses against the outer surface of the connecting block 41, causing the sealing strip 4 to... It is pressed between the two top covers 2 to form a seal.
