Description
Technical field
The utility model relates to a kind of oil tank car bonnet, is specifically related to a kind of center pressure formula fuel tank truck manhole.
Background technology
Manhole cover is divided into tri-kinds of A, B, C according to its purposes again, and the manhole cover of every kind of model has the position that it need to use, generally according to ship design and classification society rule's number of sizing.The standard size of manhole cover is 420X380 simultaneously, and this holds people's turnover, and also having large size is for someone meets accident below, and rescue personnel can transport safely next size the wounded.
Also have a class manhole cover to be used on storage tank, manhole cover is also called normal pressure manhole lid, quick opening manhole, and the fuel tank truck manhole that my company produces mostly is double-screw bolt manhole cover.This manhole cover is mounted in oil tank car body top, be for people pass in and out tank railway carriage or compartment passage, check the porthole of natural situation in goods and tank.
Because manhole cover area is larger, under using for a long time, manhole cover is distortion easily, makes lid reach identically with hole, causes truck tanker cannot reach sealing effectiveness.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of center pressure formula fuel tank truck manhole, and this manhole cover structure is easy, opens and closes more conveniently, can avoid the distortion of lid center, the service life of having improved lid simultaneously.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of center pressure formula fuel tank truck manhole, it comprises lid, on lid, be provided with manhole cover, describedly on lid, be provided with a mount pad, on this mount pad, by bearing pin, be provided with a depression bar, the termination of described depression bar is provided with a screw rod, in the bottom of screw rod, be connected with a lock dog, on the screw rod above depression bar, be also provided with a flange, fix a hanger on described manhole cover, described hanger is connected with depression bar by adapter shaft.
Described depression bar and mount pad connecting place adopt arcuate structure.
Described manhole cover edge extends to surrounding, and forms a draw-in groove.
Described lock dog and draw-in groove are used in conjunction with.
The beneficial effects of the utility model are:
1) by add a hanger being connected with depression bar at manhole cover top, by after manhole cover closure, by depression bar, to manhole cover top, apply a pressure, make manhole cover keep form;
2) by screw rod bottom, a lock dog being set, and drive screw rod by flange, lock dog is locked in draw-in groove, thereby reaches a locking action.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
