The device has the advantages that faults such as corrosion, blockage and the like can occur to various instrument gates due to changes of natural environment, properties of media in the pipe network flow and pressure and temperature, and therefore, facilities on the pipe network flow can be frequently disassembled, maintained or verified and maintained. Because various instruments, gates and pipe network flow are connected by various facility technical requirements or different distribution proportions of field equipment, after disassembly is completed, pipe network flow flanges before and after the site are staggered, after maintenance, verification and other work is completed, when reinstallation is carried out, butt joint installation difficulty is high, and due to the fact that no standard operating tool exists, a crow bar or a pipe fitting is often used for rough skid mounting, construction time consumption is long, labor intensity of workers is high, equipment damage or personnel injury can be caused carelessly, and normal production management work is affected. In order to change the above situation, a field needs an installation operation device to realize safe and standardized operation.
In the current production management process, when a gate or other equipment facilities break down, the gate or other equipment facilities are disassembled for maintenance and are updated for installation, the connecting flange is dislocated due to gravity sinking of a pipe network flow or the connecting tension of other equipment in the front and at the back, the operation is required to be crossed by multiple persons and is not standardized, the installation task can not be completed safely on time, and the damage or the injury of the personnel of newly-installed equipment facilities can be caused in the carelessness.
Through search, the same technical scheme as the disclosed technical scheme of the application is not found.
