Description

Technical Field

[0001] The utility model relates to the technical field of tank trucks, in particular to an automatic opening and closing device for a tank truck upper cover. Background Art

[0002] Tank trucks, specialized vehicles designed for transporting liquids, gases, or bulk solids, play a vital role in modern logistics and industrial transportation. These vehicles typically consist of a body, tank, chassis, and ancillary equipment. Their core feature lies in their loading portion—the tank. Depending on the transported medium, the tank can be constructed of stainless steel, aluminum alloy, or other specialized materials to ensure corrosion resistance, pressure resistance, and superior sealing properties. Tank trucks are widely used in a variety of fields, including petrochemicals, food and beverages, medicine, and agriculture, enabling the safe and efficient transportation of various materials such as fuel, liquefied gas, milk, alcohol, and fertilizers. With technological advancements, modern tank trucks have also incorporated intelligent management systems, such as GPS positioning, remote monitoring, and liquid level detection. These not only improve transportation efficiency but also greatly enhance the safety and traceability of the transportation process.

[0003] The design of a tank truck's roof is a crucial component of its structure, directly impacting the tightness, safety, and loading and unloading efficiency of the cargo. Traditional tank truck roofs often utilize bolt fastening or hydraulic locking mechanisms to prevent accidental opening due to jolts or external forces during transportation, potentially causing leaks. In recent years, advancements in materials science and mechanical automation have led to increasingly diverse and intelligent designs for tank truck roofs. For example, roofs constructed from lightweight, high-strength composite materials not only reduce vehicle weight and improve fuel efficiency, but also enhance corrosion resistance.

[0004] Under the current technical framework of tank trucks, the problem that the tank truck cover cannot be opened and closed automatically is particularly prominent. This not only greatly increases the complexity and time cost of the operation, but also due to the heavy weight of the cover itself, there are many disadvantages in the manual opening and closing process. On the one hand, the lack of special protective devices makes the cover vulnerable to damage in harsh environments. On the other hand, manual operation of the heavy cover is not only labor-intensive, but also poses safety hazards. Once improperly operated, it may cause personal injury or damage to the cover. These design deficiencies not only increase the maintenance burden, but also significantly increase the operational risk. Therefore, it is particularly urgent and important to develop a cover protection system that can automatically and efficiently open and close, effectively resist the invasion of harsh environments, and reduce the burden of manual operation.

The limit frame 6 will drop to the wedge-shaped surface 16 and contact the tank cover 14, ensuring that the tank cover 14 is tightly closed, and can achieve further fixation of the tank cover 14, and the setting of the wedge-shaped surface 16 enables the limit frame 6 to slide up and down freely without getting stuck.

[0026] As a preferred technical solution of this embodiment, a groove 15 is provided on one side of the protective frame 4; when the tank cover 14 is opened to a certain angle, the groove 15 is provided to prevent the tank cover 14 and the protective frame 4 from blocking each other.

[0027] As a preferred technical solution of this embodiment, an electric slider 3 is installed inside one of the chutes 2 and is fixedly connected to the protective frame 4. The electric slider 3 is a conventional technology. When the electric slider 3 moves within the chute 2, it drives the protective frame 4 to move with it, thereby controlling the opening and closing of the tank lid 14 through the transmission assembly. By controlling the movement direction and speed of the electric slider 3, the degree and speed of opening and closing of the tank lid 14 can be precisely controlled.

[0028] As a preferred technical solution of this embodiment, a sealing ring 17 is fixedly mounted on the bottom end of the tank lid 14, which is sealed with the connecting pipe 10. The design of the sealing ring 17 ensures a tight connection and a tight seal between the tank lid 14 and the connecting pipe 10. When the tank lid 14 is closed, the sealing ring 17 fits tightly against the top of the connecting pipe 10, preventing leakage of the tank contents and the ingress of external impurities.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
