Problems solved by technology

[0002] In the process of oil and gas exploration and development, for the purpose of safe drilling, a ram blowout preventer must be installed at the wellhead. The ram blowout preventer currently used has a blowout preventer housing and side doors that are the main pressure-bearing components. , and the opening of the side door of the ram BOP generally has two structural forms: side opening and direct opening, and the connection between the side door of the ram BOP and the BOP shell is generally completely bolted; during use, Due to pressure and wear and other reasons, it is often necessary to overhaul the ram BOP and replace the ram and other parts installed in the BOP shell. In order to open the side door, under the current bolt connection method, the connecting bolts must be removed. Then after maintenance or replacement of
