Description

Rubber seal ring mounting tool Technical Field The invention belongs to the technical field of maintenance of petroleum logging coring equipment, and particularly relates to a rubber seal ring mounting tool. Background The development of the marine oil and gas resources has become a hot spot and a focus of the world marine economic development, the marine oil and gas resources have not only large reserve, but also the modern scientific technology has great capability for the development of the marine oil and gas resources, and the marine oil and gas industry has developed into an emerging dominant industry with high yield value in the marine economy. Oil logging and coring are two most core technical means for acquiring underground geological information in oil and gas exploration and development, and the logging and coring equipment generally utilizes rubber sealing rings to realize sealing between two adjacent parts. When the staff performs equipment maintenance, the staff deforms the rubber sealing ring through the rope and then the rubber sealing ring is sleeved on the connecting column of the logging and coring equipment. The following problems occur in the maintenance process due to the fact that no proper installation tool and personnel operation modes are different: 1. when in installation, the deformation amount of the sealing ring cannot be accurately controlled due to different using force of personnel, so that the installation is inconvenient; 2. the whole sealing ring cannot be uniformly deformed in the wire rope stretching process, so that the sealing ring is extremely easy to break; 3. The installation process requires the axial rotation and stretching of the thread rope, and the risk of damage to the inner sealing surface of the sealing ring is easy to occur; 4. the probability of fracture and damage of the rubber sealing ring is extremely high, and the resource is extremely wasted (about 50 percent of damage rate); 5. the maintenance staff strength is increased due to the difficulty and the large number of the installation; 6.
