In addition, the outer side of the first folding railing is connected to the flip cover by a slide rail, a slider and a universal hinge seat. When the hanging opening needs to be opened, the telescopic rod of the hydraulic cylinder is extended to drive the flip cover to stand up and open. In the process of flipping and opening the flip cover, the sliding cover will slide downward under the guidance of the guide chain mechanism and the sliding mechanism by gravity to overcome the elastic force of the gas spring. At the same time, the first folding railing is driven by the universal hinge seat on the flip cover to flip and open. When the first folding railing is unfolded upward, the second folding railing is also unfolded and erected upward.

In the process of sliding the slider, it will drive the first folding railing to flip and fold downward. When the first folding railing flips, it will drive the second folding railing to flip. When the flip cover is flipped to a horizontal position, the first folding railing and the second folding railing are folded together and are located under the flip cover. At this time, the flip cover and the sliding cover completely close the hanging opening, thereby realizing the closure of the hanging opening.

[0016] Therefore, when the hydraulic cylinder drives the flip cover to open or close, it can also drive the first folding railing, the second folding railing and the sliding cover to open or close at the same time. There are few driving structures, and multiple structures form a chain mechanism. The flip cover, the first folding railing, the second folding railing and the sliding cover are operated synchronously. The structure is simple, and the whole process is completed automatically without manual participation, saving manpower, realizing the fully automatic opening and closing of the hanging port cover device, and improving the opening and closing efficiency of the hanging port.

[0017] 2. By setting the guide chain structure as a structure of a support slide, a support slide, a smooth wheel and a gas spring, when the flip cover is flipped, it will drive the support slide to flip and rotate. After the support slide flips and rotates, it will drive the smooth wheel to rotate, and then drive the sliding cover to slide.

[0018] 3. By connecting the two hydraulic cylinder supports on the same side through a connecting rod, the connection degree of the two hydraulic cylinder supports is improved, thereby improving the stability of the hydraulic cylinder supports.

[0019] 4. An inspection port is provided on the flip cover near the hydraulic cylinder to facilitate the inspection of the hydraulic cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
