Abstract
A manhole protecting device is arranged in a manhole of a deck and comprises a cylindrical web, a face plate and a protective barrier. The outside surface of the web is matched with the inner wall of the manhole, a first through hole in the middle of the web allows a user to pass through conveniently, the face plate is fixed at the top of the web, a second through hole matched with the first through hole is formed in the middle of the face plate, the area of the face plate is larger than that of the manhole, and the face plate is provided with the protective barrier. By the arrangement of the protective barrier, the user can be effectively prevented from missing steps, and integral security is improved; in addition, by the application of a rubber gasket, water in the deck is effectively isolated and prevented from flowing into a cabin; the manhole protecting device is simple in overall structure, convenient to maintain and light in weight.
Description
Technical field

Utility model content
The purpose of this utility model is to provide a kind of manhole protective device that can effectively prevent that personnel from falling.
For solving the problems of the technologies described above, the utility model provides a kind of manhole protective device, be arranged on the manhole on deck, comprise web, panel and protection railing, described web is cylindric, the adaptive manhole inwall of web outside face, first through hole at web middle part is convenient to user and is passed through, and described panel is fixed on web top, and second through hole suitable with the first through hole offered at panel middle part, the area of panel is greater than people's hole area, on described panel, is provided with protection railing.
For ease of user, facilitate access manhole, the utility model improves to be had, and described the first through hole and the second through hole are waist-shaped hole.
The utility model further improves and has, and described protection railing comprises montant and circular arc bar, three vertical being fixed on panel of montant, and montant upper end connects as one by circular arc bar.
For strengthening the waterproof effect of whole manhole protective device, the utility model improves to be had, and panel below is provided with rubber sheet gasket, and rubber sheet gasket is set on web.
For guaranteeing to alleviate on the basis of protection railing intensity the weight of protection railing, the utility model improves to be had again, and described protection railing is made by steel pipe.
The beneficial effects of the utility model are: by the setting of railing, effectively prevent that user from stepping on sky, improve overall security, in addition by the setting of rubber sheet gasket, actv. has been isolated the water on deck, prevent that water from flowing in cabin, whole manhole protective device structure is simple, easy to maintenance, and lightweight.
