The socket-spigot interface can improve fastening reliability, extend structure service life, decrease pipeline maintenance costs, and enable easy optimization simulation of an interface structure, increasing pipeline transport capability.

The invention discloses a ship manufacturing method for pre-mounting a steering engine base in a segmentation step. The ship manufacturing method comprises the following steps of: carrying out segmentation on a deck of a steering engine room; drawing a gantry arrangement and reinforcement picture of an upper gantry of the deck of the steering engine room at a positive segmentation state; incorporating the gantry arrangement and reinforcement picture with a segmental fitting-out tray management list so as to ensure that the pre-mounting of the steering engine base is completed in a segmental manufacturing step, and the requirement on installation precision can be met; and conveying the deck of the steering engine room in a segmental manner to a next process in a positive state of the upper gantry. The steering engine base is welded before being coated in a segmental manner, so that the segmental fitting-out integrality can be improved. Therefore, the damage area of a coating layer of a ship stern ballast cabin is reduced, the risk of sand wash on the entire ship stern ballast cabin can be effectively reduced, a coating construction period is shortened, and a PSPC (Performance Standard for Protective Coatings) can be met.

The invention discloses a penetration piece doubling plate pre-tightness manufacture and check method in ship section outfitting, which comprises the following steps that: a penetration piece doubling plate with the screw hole specification of M10 is manufactured and classified into an outfitting bill of material management list, and is preassembled in a section manufacturing stage; a doubling plate manufacturer processes tightness screw holes according to a tightness screw hole standard, a marine pipe fitting factory manufacture a penetration piece, and a section manufacturer performs section preassembly; and two screw holes on the doubling plate are respectively provided with a pressure gage and a compressed air pipe through a special connecting piece, the welding line tightness state is checked, and the two M10 screw holes are subjected to repair welding and are detected by a dye penetrant inspection method to meet the tightness requirement so as to achieve the penetration piece doubling plate welding line pre-tightness. The welding line of the doubling plate of the penetration piece is subjected to a tightness test before section coating, so that the completeness of the section coating is improved; therefore, a coating damage area of a ship space is reduced, the coating construction period is shortened, and the new performance standard for protective coatings (PSPC) is met.

The invention discloses a mounting method for templates of a box-type steel skeleton inclined column, which comprises the following steps that 1) a steel reinforcement cage of a steel skeleton is bound by steel reinforcements; 2) a column foot template and a column body template of the inclined column are subjected to lofting; a variable cross-section wire is put at the steel skeleton; 3) a template support is welded at a variable cross section; 4) templates are assembled and reinforced; double-groove steel is adopted as template reinforcing main ribs; and 5) a supporting frame is erected by the templates. The mounting method for the templates of the box-type steel skeleton inclined column has the benefits that 1) as the double-groove steel is adopted as the template reinforcing main ribs, welding of an anchor bolt on an inclined column body, subsequent cutoff and surface repair of concrete are avoided effectively; and 2) the steel reinforcement support is welded at the variable cross section of the column for bearing the pressure of the column body template, the probability of instability of the column foot template due to the pressure is reduced, and the probability of repeated position adjusting processes of the column foot template and the column body template is avoided.

The invention provides an automatic yarn hooking and shearing device for repairing an artificial lawn. The automatic yarn hooking and shearing device is characterized by comprising a pair of hooking and shearing dual-use scissors, which is connected with a scissors connecting rod piece, a scissors driving device can drive the hooking and shearing dual-use scissors to shear off yarns through the scissors connecting rod piece, the pair of hooking and shearing dual-use scissors comprises a first part and a second part, the middle parts of the first part and the second part are connected by adopting a relative rotating manner, the upper part of the first part is shaped like a hook which can hook the yarns, the lower end of the first part is fixed on a base, and the upper part of the second part is connected with the scissors driving device through the scissors connecting rod piece. The repairing of the lawn completed by workers through a series of yarn hooking and shearing operations can be avoided through adopting automatic yarn hooking and shearing task, a great amount of manpower can be saved and the working efficiency can also be improved, and the current blank of lack of technology of automatically repairing the artificial lawn can be filled up.

The invention provides a safety protection tool in a shipbuilding flat section production line. The safety production tool solves the problems that in an existing section production line, due to the fact that space between every two adjacent steel plates is difficult to keep, a person can be hurt through clamping or the steel plates can be damaged through crash.
