Description

Technical Field

[0001] The utility model relates to a manhole cover plate on a roof, in particular to a manhole cover plate mechanism on a roof adjacent to a parapet wall with a drainage function. Background Art

[0002] The manhole on the roof is a hole that can be used to access the roof surface for maintenance, inspection and cleaning of the roof; some manholes on the roof are closely attached to the parapet and the elevator shaft wall. The cover plate on the manhole on the roof installed at this position is affected by rain and the pressure from the parapet, as well as the rain on the elevator shaft roof, and the rain will leak into the manhole on the roof; the traditional manhole cover on the roof is a flip-up cover. Since the cover is relatively heavy and the opening and closing are not easy to control, the operator operates in mid-air, which is very dangerous and may hit the head when closing, posing a safety hazard; therefore, it is necessary to improve the structure of the traditional manhole cover on the roof, and design a portable manhole cover on the roof that is simple in structure, easy to process, flexible to open, safe and reliable to use, and meets the drainage function. Summary of the invention

[0003] The utility model provides a manhole cover plate mechanism on a roof adjacent to a parapet wall with a drainage function, which overcomes the above-mentioned problems existing in the existing cover plates.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A manhole cover plate mechanism on a roof adjacent to a parapet with a drainage function comprises a roof surface, an upper manhole is arranged on the roof surface, a parapet is arranged on the rear side of the upper manhole, an elevator shaft wall is arranged on the right side of the upper manhole, a roof surface transverse partition is arranged between the upper manhole and the parapet, a roof surface longitudinal partition is arranged between the upper manhole and the elevator shaft wall, a rear guide rail is arranged on the roof surface transverse partition, a front guide rail is arranged on the roof surface in front of the upper manhole, a transverse U-shaped drainage groove is arranged on the roof surface transverse partition on the rear side of the rear guide rail, a longitudinal U-shaped drainage groove is arranged on the roof surface longitudinal partition, and a movable cover is arranged between the front guide rail and the rear guide rail.

[0006] The front guide rail and the rear guide rail are both channel steel guide rails, a four-wheel trolley is movably arranged in the channel steel guide rail, a vehicle frame bolt is arranged on the four-wheel trolley, a lower clamping nut and an upper clamping nut are respectively arranged on the vehicle frame bolt, and a movable cover plate is arranged between the lower clamping nut and the upper clamping nut.

[0007] The movable cover is made of plywood, rock wool board, wooden board and aluminum board stacked in sequence.

[0008] The utility model transforms a traditional flip-type cover into a sliding cover, which effectively solves the problem that the cover is heavy, difficult to operate when the flip cover is opened, and there is a safety hazard; the U-shaped gutter of the utility model has the effect of effectively draining rainwater flowing down from the parapet adjacent to the upper manhole. BRIEF DESCRIPTION OF THE DRAWINGS
