Integrated lifting and pivoting device
A tank having a sealing plate and a tank body and lifting mechanism for separating the sealing plate from the tank body of a tank are provided. The lifting mechanism includes a pin inserted into a flange of the tank body extending through the sealing plate, and a threaded device coupled to the sealing plate and selectively contacting the pin to apply a pushing force in response to the threaded device being inserted into the sealing plate.
1. A lifting mechanism for separating a sealing plate from a tank body of a tank, the lifting mechanism comprising:
a pin inserted into a flange of the tank body extending through the sealing plate;
a threaded device coupled to the sealing plate and selectively contacting the pin to apply a pushing force in response to the threaded device being inserted into the sealing plate; and
a base flange extending upward from the sealing plate, wherein the threaded device engages the base flange; and
wherein the pin extends entirely through the sealing plate and at least partially into the base flange.
2. The lifting mechanism of claim 1 , wherein the base flange includes a threaded surface that engages the threaded device to translate rotation of the threaded device into vertical movement of the threaded device; and
wherein the vertical movement of the threaded device selectively increases and decreases insertion of the threaded device into the base flange.
3. The lifting mechanism of claim 2 , wherein the threaded device includes a tool head configured to engage a tool to facilitate rotation of the threaded device.
4. The lifting mechanism of claim 2 , wherein the pin has a length shorter than a height of the base flange and does not contact the base flange when inserted into the base flange.
5. The lifting mechanism of claim 2 , wherein the pin is positioned at a diameter from a centerline of the tank body that is less than an outer diameter from the centerline of the tank body.
6. The lifting mechanism of claim 2 , wherein the pin has a cylindrical shape and provides a pivot point for the sealing plate to rotate relative to the pin.
7. A tank comprising:
a tank body comprising a bolt flange;
a sealing plate coupled to the tank body to selectively seal the tank body adjacent the bolt flange;
a pin inserted into the bolt flange of the tank body and extending through the sealing plate;
a threaded device coupled to the sealing plate and selectively contacting the pin to apply a pushing force in response to the threaded device being inserted into the sealing plate;
wherein the sealing plate further comprises a base flange extending upward from the sealing plate;
wherein the threaded device engages the base flange; and
wherein the pin extends entirely through the sealing plate and at least partially into the base flange.
8. The tank of claim 7 , wherein the base flange includes a threaded surface that engages the threaded device to translate rotation of the threaded device into vertical movement of the threaded device; and
wherein the vertical movement of the threaded device selectively increases and decreases insertion of the threaded device into the base flange.
9. The tank of claim 8 , wherein the threaded device includes a tool head configured to engage a tool to facilitate rotation of the threaded device.
10. The tank of claim 8 , wherein the pin has a length shorter than a height of the base flange and does not contact the base flange when inserted into the base flange.
11. The tank of claim 8 , wherein the pin is positioned at a diameter from a centerline of the tank body that is less than an outer diameter from the centerline of the tank body.
12. The tank of claim 8 , wherein the pin has a cylindrical shape and provides a pivot point for the sealing plate to rotate relative to the pin.
