The application discloses a kind of vertical assembly construction methods of steel bifurcated pipe, comprising the following steps: one, the tile of steel bifurcated pipe and crescent rib plate are made;Two, pre-assembled platform is set and steel bifurcated pipe lofting is carried out;Three, pre-assembled steel bifurcated pipe;Four, steel bifurcated pipe inner support is set;Five, steel bifurcated pipe disassembly;Six, steel bifurcated pipe transportation after disassembly;Seven, steel bifurcated pipe is assembled again.The application is welded positioning block on the tile of steel bifurcated pipe by pre-assembled segment of steel bifurcated pipe, and vertical assembly method is used to assemble steel bifurcated pipe, so that steel bifurcated pipe assembly difficulty is reduced, crescent rib plate and each tile assembly positioning, adjustment is simple;Tile assembly process is single, and deformation is small, and assembly quality is higher, after assembly, high-difficulty welding such as a lot of vertical welding and overhead welding is reduced, effectively improve the steel bifurcated pipe weld quality and efficiency;Positioning is accurate and stable using positioning block, greatly reduce the bifurcated pipe assembly difficulty again.

The utility model relates to the technical field of laser solder ball welding machine nozzles, in particular to a laser solder ball spraying soldering machine nozzle which comprises a nozzle pipeline body, and the bottom end of the nozzle pipeline body penetrates through and is fixedly connected with a first screwing connecting piece. When the nozzle needs to be overhauled and maintained after being used for a period of time, the locking state is relieved by removing the locking piece, inserted into the locking insertion hole, between the first extending locking plate and the second extending locking plate, then the second screwing connecting piece is screwed out to take down the nozzle, and the old nozzle is reserved for standby application or directly restored after being overhauled and maintained. And a new nozzle can be directly replaced without delaying the production work, so that the maintenance efficiency of equipment is effectively improved.

The ultrasonic welding equipment comprises a base, an ultrasonic generator is arranged in the base, a supporting frame is arranged on the base in a rotating fit mode, a pressing frame is arranged on the supporting frame in a sliding fit mode, a protective cover is fixed to the supporting frame, a water pumping structure is arranged on the protective cover, and the water pumping structure communicates with the protective cover; an elastic sealing plate is clamped and fixed at the bottom of the protective cover; the welding structure comprises an energy converter, an amplitude-change pole and a welding head, and the energy converter is fixedly connected with the welding head through the amplitude-change pole. According to the ultrasonic welding equipment for ship maintenance, the supporting frame is installed on the base, the protective cover is installed on the supporting frame, firstly, the position and angle of the welding head can be adjusted through rotation of the supporting frame, and therefore flexible adjustment can be conducted according to different welding machine objects on a ship, and the application range of the equipment is widened; and the welding head can be protected through the protective cover, so that the service life of the welding head is prolonged.
