Abstract
Description
Technical Field
[0001] The utility model relates to an anti-collision structure, in particular to a flip anti-collision structure for a manhole valve protection cover on a tank top. Background Art
[0002] As a multimodal transport container for transporting bulk liquids and dust, tank containers usually have manholes, air ball valves, safety valves, inlets and outlets and other loading and unloading and safety accessories concentrated on the top, and are protected by installing protective covers.
[0003] The protective cover usually consists of a box base, a box cover and a rotating mechanism for opening and closing the box cover; a handle is usually provided on the box cover; a small hole is usually opened at the lowest point of the box base or a discharge pipe is connected to discharge the liquid overflowing during cleaning or loading and unloading.
[0004] For ease of use, the opening direction of the protective cover box lid is along the longitudinal direction of the tank container. For the protective cover box lid that opens longitudinally, the box lid will collide violently with the tank body or the walkway during its falling process. The paint on the surface of the tank body and the rotating mechanism at the root of the box lid are easily damaged at the moment of the collision, and a large noise is generated during the collision.
[0005] To solve the above problems, Figure 1 As shown, the existing protective cover usually adds a chain 03 between the box cover 02 and the box seat 01 to prevent the box cover 02 from colliding with the tank body 001 or the walkway during the falling process. However, with this structure, on the one hand, the flip angle of the box cover 02 is usually around 150°, which is not on the same horizontal plane as the walkway. When the operator walks on the walkway, it is easy to trip, affecting the safety of loading and unloading operations; on the other hand, the top chain plate 04 used to connect the chain 03 and the box cover 02 in this structure is usually connected to the box cover 02 by welding, and it is easy to break at the weld during use. If the breakage damage occurs, on-site welding is required when replacing the chain 03 or the top chain plate 04, which is inconvenient to operate, and will cause the box cover 02 to deform during long-term use.
