DETAILED DESCRIPTION

[0020] To clearly illustrate the technical features of the scheme, the utility model is described in detail below through a specific implementation manner and in combination with the drawings.

[0021] In addition, in the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0022] As shown in Figures 1-4 A gate well plugging cover structure, including an upper plugging plate 1, a lower grid plate 2 and a lifting wheel component 3, the upper plugging plate 1 is designed to be adapted to the shape of the gate well mouth, generally rectangular, this application takes a rectangular as an example for description, the lower grid plate 2 is also rectangular, one edge of the lower grid plate 2 is hinged to one edge of the upper plugging plate 1, including the left edge, right edge, front edge or back edge in the drawing, so that the lower grid plate 2 can rotate relative to the upper plugging plate 1, the maximum limit position of the lower grid plate 2 rotating upward is that the lower grid plate 2 and the upper plugging plate 1 are in the same plane, the maximum limit position of the lower grid plate 2 rotating downward is that the lower grid plate 2 is parallel to the upper plugging plate 1 and fits the lower surface of the upper plugging plate 1, so that two plugging is formed when plugging the gate well mouth, improving the safety of plugging, and when opening the gate well mouth, the upper plugging plate 1 and the lower grid plate 2 are opened in turn, especially the upper plugging plate 1 can be opened, and the lower grid plate 2 can be opened alone, so that the staff can safely pass through the lower grid plate 2 to observe the situation inside the gate well mouth.

[0023] In addition to the above structure, the lifting wheel component 3 is also included, the lifting wheel component 3 is provided in multiple, including three or four, the number of lifting wheel components 3 can be set according to the size of the upper plugging plate 1, the multiple lifting wheel components 3 are uniformly distributed on the upper plugging plate 1, the lifting wheel component 3 of the present application is provided in four, the four lifting wheel components 3 are correspondingly provided at the four corners of the upper plugging plate 1. Each lifting wheel component 3 includes a lifting component and a traveling wheel 303, the diameter of the traveling wheel 303 is smaller than the height of the lower grid plate 2, so that the traveling wheel 303 can be completely lifted into the lower grid plate 2, at the same time, the radial width of the traveling wheel 303 is smaller than the width of a single grid slot 11 of the lower grid plate 2, so that the traveling wheel 303 can pass through the upper grid plate and be located above it or in the grid slot 11. The lifting component driving the traveling wheel 303 to lift or retract is movably arranged on the upper plugging plate 1, the movably arranged here means rotatingly arranged, for example, connected through a bearing 4, the lifting component drives the traveling wheel 303 to extend to the bottom surface of the lower grid plate 2 or retract above the bottom surface of the lower grid plate 2.

[0024] When the cover plate needs to be moved to the manhole opening, the walking wheel 303 is lowered below the lower grating plate 2 by operating the lifting component, and a single person can push or pull the cover plate to the manhole opening, and then seal the cover plate in the manhole opening. When the cover plate needs to be stored or transported, the walking wheel 303 is raised above the lower grating plate 2 by operating the lifting component, that is, the walking wheel 303 is retracted into the lower grating plate 2, thereby reducing the space occupied during storage or transportation.

[0025] Further, the specific structure of the lifting component includes a screw sleeve 301 rotatably arranged on the upper surface of the upper sealing plate 1, and a screw rod 302 threadedly connected in the screw sleeve 301. The upper sealing plate 1 is vertically provided with a through hole 5 corresponding to the position of the screw sleeve 301, and the screw rod 302 is connected with the walking wheel 303 through the through hole 5. When the height of the walking wheel 303 needs to be adjusted, one hand holds the top end of the screw rod 302 to prevent the screw rod 302 from rotating with the screw sleeve 301, and the other hand twists the screw sleeve 301, which is very convenient to adjust.

[0026] Further, in order to improve the sealing performance of the upper sealing plate 1, a flexible sealing gasket 7 is arranged around the side surface of the upper sealing plate 1.

[0027] Further, in order to facilitate the handling and moving of the cover plate and avoid the instability of the moving process caused by the rotation of the lower grating plate 2 around the hinge, a magnet 10 is arranged on the lower surface of the upper sealing plate 1, and the magnet 10 is arranged away from the edge of the lower grating plate 2. When the cover plate is sealed or handled and moved, the lower grating plate 2 is attracted to the lower surface of the upper sealing plate 1 through the magnet 10. When the upper sealing plate 1 needs to be opened to view the manhole opening, the upper sealing plate 1 is pulled away from the edge of the hinge, and an external force forcibly separates the upper sealing plate 1 from the lower grating plate 2. In this way, only the upper sealing plate 1 can be opened to view the gate opening through the lower grating plate 2.

[0028] Further, in order to facilitate the manual disassembly of the cover plate from the manhole opening and facilitate the upward pulling of the upper sealing plate 1 when viewing the gate opening, a mounting groove 8 is further arranged on the upper surface of the upper sealing plate 1, and a handle 9 is arranged in the mounting groove 8. The upper surface of the handle 9 is flush with the upper surface of the upper sealing plate 1.

[0029] Further, a recess 6 is arranged on the lower surface of the upper sealing plate 1, and the recess 6 is located directly above the walking wheel 303. This is to ensure that when the left and right lengths of each grating groove 11 of the lower grating plate 2 are insufficient to allow the walking wheel 303 to rotate with the upper sealing plate 1, the existence of the recess 6 can increase the height of the walking wheel 303, thereby realizing the rotation of the walking wheel 303 out of the grating groove 11 with the upper sealing plate 1.

[0030] The specific embodiments above cannot be used as a limitation to the protection scope of the utility model, and any alternative improvement or transformation made by the skilled in the art to the utility model embodiments falls within the protection scope of the utility model.

[0031] The parts not described in the utility model are the common technology of the skilled in the art.
