Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Specific embodiments are described below in conjunction with the drawings of the specification:
please refer to fig. 1 and 2, the pressure vessel self-sealing manhole door dismounting tool of the present invention includes an operation rod 1 and a connection member 2, the operation rod 1 includes a short rod 3 and a long rod 4, the short rod 3 and the long rod 4 are vertically fixed and connected, the right end of the long rod 4 is provided with a plug connection end 5, the plug connection end 5 is provided with a first through hole 6, the connection member 2 includes a connection plate 7 and two connection lugs 8 symmetrically arranged, the connection lugs 8 are coaxially provided with a second through hole 9, and two sides of the connection plate 7 are provided with fixing holes 10. The operating rod 1 and the connecting piece 2 are connected through the first through hole 6 and the second through hole 9, and can rotate by 90 degrees left and right, namely, the two are hinged.
When the oval manhole door is installed, the connecting piece 2 is installed at an auxiliary connecting position on the outer side of the manhole door, and the auxiliary connecting position is provided with a connecting structure, such as a threaded hole, and is connected with the fixing hole 10 of the connecting piece 2 through a bolt; then, the inserting connection end 5 of the long rod 4 is inserted between the two parallel connection lugs 8 of the connecting piece 2, the first through hole 6 and the second through hole 9 are aligned, and then the bolt and the nut are inserted for connection, if a stud bolt and a nut are adopted, the connection lug 8 is hinged with the inserting connection end 5 of the long rod 4, so that the position and the angle of the manhole door can be adjusted conveniently in the installation process.
After accomplishing above-mentioned operation, with chain block's lifting hook fixed connection action bars 1's stock middle section, oval manhole door needs turned angle and position just can push oval manhole downthehole, then control action bars 1's quarter butt 3. The ellipse has a major axis and a minor axis, and the position of the ellipse is described below in the major axis direction and the minor axis direction. If oval manhole is the vertical setting of major axis direction, then should make the minor axis direction of oval manhole door keep vertical this moment, and the major axis direction keeps the level, promotes connecting piece 2 and drives oval manhole door removal after that, and then penetrates oval manhole door downthehole, and rotatory manhole door again adjusts suitable position and carries out fixed mounting.
