The manhole cover is composed of a hinge, a movable door body, a sealing piece, a manhole inner sealing head, a pressure tank body, a manhole barrel, a screw rod mounting seat, a manhole outer sealing head, a connecting screw rod, a connecting support, a locking washer and a nut. The utility model discloses an adopt interior open people's door structural style, satisfying under the large-scale overhead tank service function condition, can prevent that large-scale pressure from pouring into people's door and overhauls and cause personnel's injury when opening the operation.
Description
Technical Field
The utility model relates to an open door of entering people in large-scale overhead tank.
Background
The large-scale overhead tank needs to be provided with the access door for the maintenance operation of the tank body, the traditional access door is outward-opening, and the movable door is positioned on the outer side of the tank body. In engineering practice, when the entrance door is detached, the entrance door is opened due to residual pressure in the pressure tank body, so that personnel injury accidents are caused.
Disclosure of Invention
The utility model aims at providing a can prevent that the staff from overhauing open into people's door in the large-scale overhead tank who causes personnel's injury when opening the operation. The technical scheme of the utility model is that: the hinge (1) is connected with the movable door body (2) and the manhole inner end cover (4), the sealing element (3) is pressed in the middle of the movable door body (2) and the manhole inner end cover (4), the manhole inner end cover (4) is connected with the manhole cylinder body (6) in a welding mode, the manhole cylinder body (6) is connected with the tank body (5) in a welding mode, the screw mounting seat (7) is installed on the outer surface of the movable door body (2) in a welding mode, the manhole outer end cover (8) is connected with the manhole cylinder body (6) in a welding mode, the connecting support (10) is in lap joint with the manhole outer end cover (8) in the longitudinal direction, one end of the connecting screw (9) is connected with the screw mounting seat (7), the other end of the connecting support passes through the connecting support (10), penetrates through the locking washer (11) and is connected.
Principle of operation
The utility model discloses to advance manhole inner cover (4), advance manhole barrel (6), jar body (5), advance manhole outer cover (8) and connect through the welding mode and become into the manhole passageway, install the movable door body (2) inside the overhead tank through hinge (1), make movable door body (2) inwards open only, can not cause the injury to overhead tank outside operating personnel. The locking and sealing of the entrance door are completed through the sealing element (3), the screw mounting seat (7), the connecting screw (9), the connecting bracket (10), the locking washer (11) and the nut (12).
Technical effects
The utility model discloses an adopt interior open people's door structural style, satisfying under the large-scale overhead tank service function condition, can prevent that large-scale pressure from pouring into people's door and overhauls and cause personnel's injury when opening the operation.

Detailed Description
As shown in fig. 1, the large-sized pressure tank internal open type manhole door comprises a hinge 1, a movable door body 2, a sealing element 3, a manhole inner end enclosure 4, a tank body 5, a manhole cylinder 6, a screw rod mounting seat 7, a manhole outer end enclosure 8, a connecting screw rod 9, a connecting support 10, a locking washer 11 and a nut 12.
The hinge 1 is used for connecting the movable door body 2 with the inner end socket 4 of the manhole, and the movable door body 2 can rotate inwards through the hinge 1 to be opened to realize the function of entering the manhole when other external connecting pieces are opened.
The sealing element 3 plays a sealing role when the movable door body 2 and the inner end socket 4 of the manhole are tightly installed.
The manhole inner end socket 4 and the manhole cylinder 6 are connected into a whole in a welding mode.
The manhole cylinder 6 is oval and is connected with the tank body 5 in a circumferential welding mode.
The screw mounting seat 7 is mounted on the outer surface of the movable door body 2 in a welding mode, the screw mounting seat 7 is cylindrical, and a threaded hole is machined in the center of the screw mounting seat.
The manhole outer end socket 8 and the manhole cylinder 6 are connected into a whole in a welding mode.
The connection bracket 10 is a bar-shaped metal rod with certain strength, two ends of the connection bracket are lapped with the manhole outer end socket 8, and a circular hole with certain size is processed at the center of the connection bracket.
Both ends of the connecting screw rod 9 are processed with standard threads, the connecting screw rod 9 is rotated to enable one end of the connecting screw rod to be connected with the screw rod mounting seat 7, and the other end of the connecting screw rod penetrates through a locking washer 11 and a screw nut 12 after penetrating through a round hole of the connecting support 10.
The nut 12 is screwed through a tool, so that the connecting screw rod 9 drives the movable door body 2 to move towards the direction close to the inner end socket 4 of the manhole, the sealing element 3 is evenly compressed, and when a certain pretightening force is reached, the nut 12 is locked and fixed by the locking washer 11, and the installation operation of the open manhole in the pressure tank is completed.
