The utility model pressure container vertically hangs the built-in manhole of lid, comprises the manhole adapter and the manhole cover that are welded on the wall of container; Two double-screw bolts of welding on the one side of manhole cover, welding fixation steel plate II and fixing steel pipe II on the manhole cover another side, pivoted arm one end are inserted in fixedly in the steel pipe II, are connected as a single entity with manhole cover and keep the manhole cover arm that rotates to carry out freely rotating.The pivoted arm other end be placed on the wall of container fixation steel plate I and fixedly in the steel pipe I, fixation steel plate I and fixedly steel pipe I be welded on the container inner wall, manhole cover is connected on the cylindrical shell through pivoted arm; Two double-screw bolts respectively connect a channel-section steel formula pretension pressing plate outside stretching out the manhole adapter on the manhole cover, and channel-section steel formula pretension pressure board by nut screwing clamping, makes manhole cover take over closed with a predetermincd tension and manhole outside manhole is taken over.
The advantage of the utility model is:
1, pivoted arm inserts fixation steel plate on the cylinder inboard wall, fixedly is connected with cylindrical shell in the steel pipe, make pivoted arm can be in cylindrical shell the certain limit left-right rotation, connection mode is simple, and moment of flexure is less relatively to the normal stress of this welding line structure generation, welded structure is reliable.
2, pivoted arm inserts fixation steel plate on the manhole cover, fixedly is connected with manhole cover in the steel pipe weldment, manhole cover can freely be rotated along pivoted arm, and connection mode is simple, and moment of flexure is less relatively to the normal stress of this welding line structure generation, and welded structure is reliable.
3, change on the wall and weld set collar, be stuck on the steel pipe on the cylinder inboard wall fixedly pivoted arm position, can freely take out pivoted arm, manhole cover, make things convenient for the maintenance of manhole cover and pivoted arm.
4, manhole is taken over and is adopted oval structure, can side direction take out manhole cover during maintenance.
5, channel-section steel is as manhole cover pretension pressing plate, good rigidly, make simple, to get material convenient, practical.
6, pressure container vertically hangs the built-in manhole structure of lid, can be used for the Pressure container manhole structure not allowing manhole to stretch out under the situation of tank wall.The not only simple operation of above structure, safe and reliable, manufacture difficulty is lower, and is with low cost.
