Rainproof removable skylight cover

Abstract

The invention discloses a rainproof removable skylight cover. The rainproof removable skylight cover is characterized in that the rainproof removable skylight cover comprises a door frame crossbeam and a skylight cover plate (2), the door frame crossbeam is provided with a crossbeam main panel (1), the lower surface of the skylight cover plate (2) is provided with a ring of lining board (3), the upper surface of the crossbeam main panel (1) is provided with a ring of baseboard (4), a sealing gasket (5) is arranged between the lining board (3) and the baseboard (4), corresponding position of the skylight cover plate (2), the lining board (3), the sealing gasket (5) and the baseboard (4) are provided with bolt holes for bolts (6) to traverse through, and an elastic pad (7) used for sealing and rain proofing is arranged between the bolt caps of the bolts (6) and the skylight cover plate (2). The rainproof removable skylight cover integrates rain proofing, removability, bearing and firm connection, and can be widely popularized and applied.

Description

technical field [0001] The invention relates to a rainproof and detachable skylight cover, in particular to a rainproof and detachable skylight cover applied to a portal crane. Background technique [0002] With the continuous development of the port logistics industry, the lifting capacity of portal cranes for loading and unloading bulk or general cargo is increasing, and the installed capacity of the whole machine is increasing. Therefore, more and more terminal power supply is changed from low-voltage power supply to high-voltage power supply. The power supply is converted to low voltage through the transformer on the machine, and the transformer is generally placed in the beam of the portal frame in the design of the portal crane, but in general, the high-voltage transformer or high-voltage cabinet is hoisted into the beam after the assembly and welding of the beam structural parts is completed. Therefore, it is required that the upper panel of the beam needs to open hoi...

Problems solved by technology

[0004] Figure 1~2 The designed skylight cover, because the cover is larger than the retaining ring hole, rainwater cannot penetrate, so it can prevent rain, and the two lifting lugs are welded on the cover, so that the skylight cover can be opened and the transformer can be lifted out of the beam for repair. The circle is large and can shake, so it can neither carry nor be fixed. When a typhoon strikes, it is easy to be blown away by the wind

[0005] Figure 3~4 The design is a flat cover, the base retainer has a flash edge at 90 degrees, and the flash edge is drilled and connected to the cover with bolts. The cover can choose a plate with the same thickness as the beam panel. After the bolts are tightened, it can bear the load and will not be blown by the wind. Walk, and the bolts are detachable, which can be used for maintenance and hoisting of transformers, but the disadvantage is that water seeps easily from the bolts and is not rainproof
